Description

Pilot frequency information transmission method, network equipment and terminal

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a pilot information transmission method, a network device, and a terminal.

Background

MulteFire is a radio access technology that extends LTE to unlicensed bands, in which unlicensed band carriers can independently provide services without the help of licensed band carriers. Mf (multe fire) physical layer introduces Listen Before Talk (LBT) mechanism of carrier sense technology like WiFi. When the base station or the terminal monitors that the unlicensed frequency band channel is occupied, namely LBT fails, the signal is stopped being sent, and when the channel is monitored to be idle, namely LBT succeeds, the signal is sent.

In order to improve the transmission efficiency of downlink common control signals of a base station under an LBT mechanism, MulteFire introduces a Discovery Reference Signal (DRS), and the DRS includes main downlink common control signals including system broadcast, Primary Synchronization Signal (PSS), Secondary Synchronization Signal (SSS), enhanced Primary synchronization Signal (ePSS), enhanced Secondary synchronization Signal (eSSS), Cell Reference Signal (CRS), main system Information Block (MIB) and enhanced system Information Block (SIB-MF). Wherein, the DRS occupies 12 or 14 symbols (symbols) in one downlink subframe.

In order to better support the Internet of Things service in the unlicensed frequency Band, the multefer organization has researched the technology of narrowband Internet of Things (NB-IoT) in the unlicensed frequency Band, that is, NB-IoT-U, and the 3GPP NB-IoT technology is introduced into the sub 1GHz unlicensed frequency Band. The unlicensed Frequency band of sub 1GHz specified by the Federal Communications Commission (FCC) in the united states is 902MHz-928MHz, when the system transmission bandwidth is less than 250KHz, the base station performs Frequency-Hopping Spread Spectrum (FHSS) certification, when the system bandwidth is greater than 500KHz, the base station may perform Digital Modulation (DM) certification, and the maximum system bandwidth of the unlicensed Frequency band of sub 1GHz recommended by the European Telecommunications Standardization Institute (ETSI) is 200 KHz.

Neither FCC nor ETSI requires LBT before devices transmit data in the sub 1GHz unlicensed band. In order to randomize the mutual interference of the unlicensed band systems, a narrowband system is generally required to perform frequency hopping in the unlicensed band, FCC stipulates that the bandwidth of the sub 1GHz unlicensed band system is less than that of the frequency hopping channel of the 250KHz system and is not less than 50, ETSI stipulates that the operating time of the sub 1G unlicensed band system in each channel does not exceed 10% of the total time, that is, at least 10 frequency hopping channels are required under the condition that the operating time of each channel is the same.

In an NB-IoT-U system, if FHSS authentication is adopted, the system bandwidth is set to 200KHz, and both a pilot channel and a data channel occupy 1 Physical Resource Block (PRB), i.e., 200 KHz. If the pilot channel is located at a random frequency hopping point of the system, the period of the pilot channel may not be fixed. And when the system frequency jumps to the frequency hopping frequency point of the pilot channel, the pilot channel is sent, and the period of the pilot channel is increased along with the increase of the total number of the frequency hopping frequency points of the system, so that the time for the terminal to initially access the base station and the time for the terminal to resynchronize are increased.

Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

As shown in fig. 1, an embodiment of the present invention provides a method for transmitting pilot information, where the method is applied to a network device in a frequency hopping communication system, where the frequency hopping communication system is configured with an initial pilot channel and an auxiliary pilot channel, and frequency hopping points of the initial pilot channel are different from frequency hopping points of the auxiliary pilot channel, and the method includes:

step 101: initial pilot information is transmitted to the terminal through an initial pilot channel.

In this step, specifically, the network device may send initial pilot information to the terminal through the initial pilot channel, where the initial pilot information includes a synchronization signal. Therefore, the initial pilot information comprises the synchronization signal, so that the terminal can perform initial synchronization or resynchronization according to the synchronization signal.

The network device may be a base station.

The synchronization signals include Primary Synchronization Signals (PSS) and Secondary Synchronization Signals (SSS).

Of course, specifically, the initial pilot information may further include initial access information, so that the terminal can perform initial access according to the initial access information.

In addition, specifically, when the initial pilot information is transmitted to the terminal through the initial pilot channel, the synchronization signal may be repeatedly transmitted multiple times in each initial pilot channel period, so that the synchronization signal may be repeatedly transmitted multiple times in each initial pilot channel period according to the requirements of the transmission power, the Maximum Coupling Loss (MCL), the Maximum Path Loss (MPL), and the like, and the quality of the synchronization signal may be ensured.

In addition, specifically, the frequency hopping frequency points of the initial pilot channel frequency domain are pre-configured in the sub 1GHz unlicensed frequency band, so that the network device can be fixed in an NB-IoT-U system to preset at least one pilot channel frequency point, and then each cell can randomly select one frequency hopping frequency point from the pre-configured pilot channel frequency points as the frequency hopping frequency point used by the cell to send the initial pilot channel; or, according to the physical cell identity (PCI for short) of the cell, one frequency hopping frequency point is selected from the pre-configured frequency hopping frequency points of the pilot channels as the frequency hopping frequency point used by the cell to send the initial pilot channel, so that the frequency hopping frequency points of the initial pilot channels selected by the adjacent cells are different, and the interference among the initial pilot channels of different cells is randomized. For example, as shown in fig. 2, a schematic diagram of setting a pilot channel frequency point every X MHz in 902MHz to 928MHz of FCC for a network device is shown. The network device may send the initial pilot channel in at least one pilot channel frequency point preconfigured in fig. 2, and at this time, the terminal may first detect the initial pilot channel in the pilot channel frequency point preconfigured in fig. 2 during initial access.

In specific implementation, when initial pilot frequency information is sent to a terminal through an initial pilot frequency channel, a first target frequency hopping frequency point of the initial pilot frequency channel can be determined from first pre-configured frequency hopping frequency points, wherein the first frequency hopping frequency point is a pre-configured pilot frequency channel frequency point; and sending the initial pilot frequency information to the terminal through the first target frequency hopping frequency point of the initial pilot frequency channel.

When the first target frequency hopping frequency point of the initial pilot channel is determined from the preconfigured first frequency hopping frequency points, the first target frequency hopping frequency point of the initial pilot channel can be determined from the preconfigured first frequency hopping frequency points according to the PCI of the serving cell of the terminal. Therefore, the frequency hopping points of the initial pilot channels of the adjacent cells are different, and the interference among the initial pilot channels of different cells is randomized.

Step 102: and transmitting the auxiliary pilot information to the terminal through the auxiliary pilot channel.

In this step, specifically, the network device may send auxiliary pilot information to the terminal through an auxiliary pilot channel, where the auxiliary pilot information includes terminal initial access information and/or resynchronization information.

Specifically, the resynchronization information is used for resynchronization of the terminal, including a synchronization signal.

The initial access information includes at least one of: system broadcast information; a main system information block (MIB); scheduling information of a system message SIB1-NB for indicating a transport block size and a number of repeated transmissions of the system message SIB 1-NB; the system information change label is used for indicating a change serial number of the system information; a paging indicator for indicating whether the network device transmits a page in a next pilot channel period; the configuration information of the uplink subframe and the downlink subframe is used for indicating the configuration of the uplink subframe and the configuration of the downlink subframe of a data channel; the frequency hopping frequency point list is used for indicating a frequency hopping frequency point set adopted by a service cell of the terminal; the system frame number is used for indicating the sequence number of the current wireless frame, wherein the range of the sequence number of the wireless frame is 0 to 1023; and the system hyper frame number is used for indicating the hyper frame sequence number of the current wireless frame, wherein the hyper frame number range is 0 to 1023.

Therefore, the initial access information and/or the resynchronization information are sent to the terminal through the auxiliary pilot channel, so that the initial access terminal can perform initial access according to the initial access information, the initial access time delay is reduced, and the terminal needing resynchronization can perform resynchronization through the resynchronization information, so that the terminal resynchronization time delay is reduced, and the problems that the pilot channel period in an NB-IoT-U system is too long, and the initial access time of the terminal and the terminal synchronization time are increased are solved.

Of course, it should be noted herein that the frequency hopping points of the initial pilot channel are different from the frequency hopping points of the auxiliary pilot channel.

Thus, the embodiment of the invention sends the initial pilot frequency information comprising the synchronous signal to the terminal through the initial pilot frequency channel, and sends the auxiliary pilot frequency information comprising the terminal initial access information and/or the resynchronization information to the terminal through the auxiliary pilot frequency channel, so that the initial access terminal can carry out initial synchronization according to the received initial pilot frequency information and carry out initial access according to the initial access information in the auxiliary pilot frequency information, thereby reducing the initial access time delay of the initial access terminal; in addition, the resynchronization terminal can perform resynchronization through the initial pilot channel or the auxiliary pilot channel, and the resynchronization time delay of the resynchronization terminal is reduced.

Further, in the embodiment of the present invention, the auxiliary pilot channel may have multiple transmission modes, and the initial pilot information transmitted to the terminal through the initial pilot channel may be different in accordance with different transmission modes. This is described in detail below.

Specifically, the transmission method of the auxiliary pilot channel may include the following two methods:

the first mode is as follows: the sending frequency point of the auxiliary pilot channel is a pre-configured frequency hopping frequency point, that is, the frequency hopping frequency point selectable by the auxiliary pilot channel is fixed, as shown in fig. 3, which is a schematic diagram when the sending frequency point of the auxiliary pilot channel is pre-configured. In fig. 3, the dotted line indicates the pre-configured hopping frequency point of the auxiliary pilot channel, and it can be seen from fig. 3 that the hopping frequency point of the auxiliary pilot channel is fixed. Because the system randomly hops to the frequency hopping point of the auxiliary pilot channel within the time of completing one frequency hopping pattern, the period of the auxiliary pilot channel may not be fixed.

The second mode is as follows: the transmission period of the auxiliary pilot channel is a pre-configured period, that is, the transmission period of the auxiliary pilot channel is fixed. Fig. 4 is a schematic diagram of the periodic transmission of the auxiliary pilot channel. In fig. 4, T represents a pre-configured period of the secondary pilot channel, and it can be seen from fig. 4 that the transmission period of the secondary pilot channel is a fixed period T. Because the system randomly hops to the frequency hopping point of the auxiliary pilot channel within the time of completing one frequency hopping pattern, the frequency hopping point appearing in the auxiliary pilot channel may not be fixed.

In addition, in the frequency hopping system, when the number of all frequency hopping points preconfigured by the system is larger than that of actually used frequency hopping points, the system generally informs the terminal of a specifically used frequency hopping point list. Specifically, the terminal may be notified in the initial pilot information through the initial pilot channel. In addition, since the initial pilot channel frequency point belongs to the frequency hopping frequency point, the initial pilot channel frequency point must belong to the system frequency hopping frequency point list. In the case that the network device indicates the frequency hopping set used by the system in the channel group mode, for example, if the frequency band from 902MHz to 928MHz of the FCC is divided into 128 200KHz frequency points and 128 channels are divided into 32 channel groups, the network device may send a frequency point list with 32 bit values, where each bit represents whether the corresponding channel group belongs to the system frequency hopping set (for example, 1 represents that the corresponding channel group belongs to the frequency hopping set and 0 represents that the corresponding channel group does not belong to the frequency hopping set), and if the number of frequency hopping frequencies of the system is required to be 64, the frequency point list needs to include 16 channel groups. The channel group to which the initial pilot channel bin belongs must be included in the channel group informed by the bin list.

It should be noted that, when the transmission frequency point of the auxiliary pilot channel is a pre-configured frequency hopping frequency point, the transmission period of the auxiliary pilot channel may be a pre-configured period at the same time; or, when the transmission frequency point of the auxiliary pilot channel is a pre-configured frequency hopping frequency point, the transmission period of the auxiliary pilot channel is not limited and can be a pre-configured period; alternatively, when the transmission period of the auxiliary pilot channel is a pre-configured period, the transmission frequency point of the auxiliary pilot channel is not limited to be a pre-configured frequency hopping frequency point. This is not particularly limited.

The following describes the transmission procedure of the secondary pilot channel and the initial pilot information in detail for different transmission modes of the secondary pilot channel.

For the first transmission mode, that is, when the transmission frequency point of the auxiliary pilot channel is a pre-configured frequency hopping frequency point, the specific content of the initial pilot information may be determined by determining whether the frequency hopping frequency point of the auxiliary pilot channel is selected from the frequency hopping frequency points in the pre-configured frequency hopping frequency points. The following is introduced for the selection of the hopping frequency point of the secondary pilot channel.

Firstly, the system can fixedly preset one or more pilot frequency channel frequency points, and each cell randomly selects one frequency hopping frequency point from the pre-configured pilot frequency channel frequency points as the frequency hopping frequency point used by the cell to send the auxiliary pilot frequency channel; or, according to the PCI of the cell, one frequency hopping frequency point is selected from the pre-configured frequency hopping frequency points of the pilot channels as the frequency hopping frequency point used by the cell to send the auxiliary pilot channel, so that the frequency hopping frequency points of the auxiliary pilot channels selected by the adjacent cells are different, and the interference among the auxiliary pilot channels of different cells is randomized.

In specific implementation, when the auxiliary pilot information is sent to the terminal through the auxiliary pilot channel, a second target frequency hopping frequency point of the auxiliary pilot channel can be determined from second pre-configured frequency hopping frequency points, wherein the second frequency hopping frequency point is a pre-configured pilot channel frequency point; and sending the auxiliary pilot frequency information to the terminal through a second target frequency hopping point of the auxiliary pilot frequency channel.

Specifically, when the second target frequency hopping frequency point of the auxiliary pilot channel is determined from the preconfigured second frequency hopping frequency points, the second target frequency hopping frequency point of the auxiliary pilot channel can be determined from the preconfigured second frequency hopping frequency points according to the PCI of the serving cell of the terminal, so that the frequency hopping frequency points of the auxiliary pilot channel selected by adjacent cells are different, and thus the interference between the auxiliary pilot channels of different cells is randomized. Meanwhile, the terminal can directly search the second target frequency hopping frequency point of the auxiliary pilot channel in the second frequency hopping frequency points which are configured in advance according to the PCI of the service cell of the terminal.

It should be noted that the preconfigured second frequency hopping frequency point and the preconfigured first frequency hopping frequency point may be the same or different, and are not limited herein.

In addition, specifically, when the second target frequency hopping point of the auxiliary pilot channel is determined from the second frequency hopping points configured in advance, the initial pilot information further includes first configuration information used for indicating the second target frequency hopping point of the auxiliary pilot channel, and the first configuration information includes at least one of the following:

1) the index value of a second target frequency hopping frequency point of the auxiliary pilot channel in the second frequency hopping frequency point; the first configuration information comprises the index value of the second target frequency hopping point of the auxiliary pilot channel in the second frequency hopping point, so that the terminal can determine the frequency hopping point of the auxiliary pilot channel when receiving the initial pilot information.

2) The offset value of a second target frequency hopping frequency point of the auxiliary pilot frequency channel relative to a first target frequency hopping frequency point of the initial pilot frequency channel; the first configuration information comprises an offset value of a second target frequency hopping point of the auxiliary pilot channel relative to a first target frequency hopping point of the initial pilot channel, so that the terminal can determine the frequency hopping points of the auxiliary pilot channel when receiving the initial pilot information.

3) The index values of a second target frequency hopping frequency point of the auxiliary pilot frequency channel in all frequency hopping frequency points; the index values of the second target frequency hopping point of the auxiliary pilot channel in all frequency hopping points are included in the first configuration information, so that the terminal can determine the frequency hopping points of the auxiliary pilot channel when receiving the initial pilot information.

4) A first frequency point list, wherein the first frequency point list comprises a second target frequency hopping frequency point; specifically, the first frequency point list is a frequency hopping frequency point adopted by a serving cell of the terminal. The frequency point list is a frequency hopping frequency point set of the system, and can include frequency hopping frequency points of one or more auxiliary pilot channels in the frequency point list. At this time, the network device may select a second target frequency hopping point for transmitting the auxiliary pilot channel from second frequency hopping points of the preconfigured pilot channel, then include the second target frequency hopping point in the first frequency point list, and transmit the first frequency point list to the terminal. Because the terminal has acquired the second frequency hopping frequency point of the pre-configured pilot channel in advance, the terminal can regard the second target frequency hopping frequency point contained in the first frequency point list as the frequency hopping frequency point of the auxiliary pilot channel configured by the network device.

5) The index value of a target frequency channel group containing a second target frequency hopping point in a pre-configured frequency channel group;

6) index values of a target frequency channel group containing a second target frequency hopping point in all frequency channel groups; the following description is made with respect to two kinds of first configuration information, 5) and 6). For example, the FCC 902MHz to 928MHz band is divided into 128 200KHz frequency bins, and the 128 frequency bins are divided into 32 channel groups. Assuming that the pilot channels are uniformly distributed in all frequency points, one pilot channel is preset in the 2 n-th channel group, or one pilot channel is preset in each channel group. Therefore, the network device may notify the frequency hopping point where the auxiliary pilot channel is located by using the index of the frequency channel group of the auxiliary pilot channel in the frequency channel groups of all the preconfigured pilot channels, or notify the frequency hopping point where the auxiliary pilot channel is located by using the index value of the frequency channel group of the auxiliary pilot channel in all the frequency channel groups.

7) And a second frequency point list, wherein the second frequency point list contains a frequency channel group of a second target frequency hopping frequency point. Specifically, the second frequency point list is a frequency hopping frequency point adopted by a serving cell of the terminal. The frequency point list is a frequency hopping frequency point set of the system, and can include frequency hopping frequency points of one or more auxiliary pilot channels in the frequency point list. When the network device selects a second target frequency hopping point from second frequency hopping points of the preconfigured pilot channel to send the auxiliary pilot information, the network device may include a frequency channel group of the second target frequency hopping point in a second frequency point list, and send the second frequency point list to the terminal. Because the terminal has previously acquired all the channel groups of the pilot channel, the terminal can identify the second target frequency hopping frequency point in the channel group contained in the second frequency point list as the frequency hopping frequency point of the auxiliary pilot channel configured by the network device, thereby determining the frequency hopping frequency point of the auxiliary pilot channel.

Specifically, if there are N frequency hopping points of the pilot channels (including the frequency hopping points of the initial pilot channel and the auxiliary pilot channel) in the system, N frequency channel groups including the frequency hopping points of the pilot channels and (M-N) frequency channel groups not including the frequency hopping points of the pilot channels are required in the frequency point list, where M is the total number of frequency channel groups selected by the network device for use in all frequency channel groups in the NB-IoT-U frequency band, and M is greater than or equal to N.

Therefore, when the second target frequency point of the auxiliary pilot channel is selected from the second frequency hopping frequency points which are configured in advance and belong to the pilot channel frequency points, at least one item of the second target frequency points is used as the first configuration information to be sent to the terminal, so that the terminal can accurately receive the auxiliary pilot channel according to the first configuration information, initial access information and/or resynchronization information of the terminal in the auxiliary pilot channel are obtained, and time delay of initial access and resynchronization of the terminal is reduced.

Secondly, when the sending frequency point of the auxiliary pilot channel is a pre-configured frequency hopping frequency point, when the auxiliary pilot information is sent to the terminal through the auxiliary pilot channel, determining a second target frequency hopping frequency point of the auxiliary pilot channel from all pre-configured frequency hopping frequency points, wherein all frequency hopping frequency points comprise a data channel frequency point and a pre-configured pilot channel frequency point; and sending the auxiliary pilot frequency information to the terminal through a second target frequency hopping point of the auxiliary pilot frequency channel. That is, at this time, the sending frequency point of the auxiliary pilot channel may be a pre-configured pilot channel frequency point, or may also be a data channel frequency point in a pre-configured frequency hopping frequency point.

Specifically, when the second target frequency hopping point of the auxiliary pilot channel is determined from all the pre-configured frequency hopping points, the second target frequency hopping point of the auxiliary pilot channel may be determined from all the pre-configured frequency hopping points according to the PCI of the serving cell of the terminal. Therefore, the frequency hopping points of the auxiliary pilot channels selected by the adjacent cells are different, and the interference among the auxiliary pilot channels of different cells is randomized.

In addition, specifically, when the second target frequency hopping point of the auxiliary pilot channel is determined from all the pre-configured frequency hopping points, the initial pilot information further includes second configuration information for indicating the second target frequency hopping point of the auxiliary pilot channel, and the second configuration information includes at least one of the following:

A) the index values of the second target frequency hopping frequency point where the auxiliary pilot frequency channel is located in all frequency hopping channels; for example, if the 902MHz to 928MHz frequency band of the FCC is divided into 128 200KHz frequency points, the network device notifies the terminal of the index of the second target frequency hopping frequency point of the auxiliary pilot channel in the 128 frequency points in the initial pilot channel.

B) The offset value of a second target frequency hopping frequency point of the auxiliary pilot frequency channel relative to a first target frequency hopping frequency point of the initial pilot frequency channel; for example, the frequency point number of the first target frequency hopping frequency point of the initial pilot frequency channel is N, the offset value of the second target frequency hopping frequency point of the auxiliary pilot frequency channel relative to the first target frequency hopping frequency point of the initial pilot frequency channel is k, and the channel number of the second target frequency hopping frequency point of the auxiliary pilot frequency channel is (N + k) mod N, where N is the total number of the system frequency hopping frequency points.

C) The index values of the second target frequency hopping frequency point of the auxiliary pilot channel in the third frequency point list;

D) and the offset value of the second target frequency hopping frequency point of the auxiliary pilot channel and the third frequency point list relative to the first target frequency hopping frequency point of the initial pilot channel is in the third frequency point list. Specifically, the network device may further send the third frequency point list in a channel group manner, which is not limited herein. In addition, if the network device only selects the data channel frequency points except the pre-configured pilot frequency channel frequency point as the frequency hopping frequency points of the cell auxiliary pilot frequency channel, the third frequency point list only includes the frequency channel group of the first target frequency hopping frequency point of the initial pilot frequency channel, and the other (M-1) frequency channel groups do not include the frequency channel group of the pilot frequency channel frequency point, where M is the total number of the frequency channel groups selected and used in all the frequency channel groups set in the NB-IoT-U frequency band by the network.

Therefore, when the second target frequency point of the auxiliary pilot channel is selected from all the pre-configured frequency hopping frequency points, at least one item of the second target frequency points is used as second configuration information to be sent to the terminal, so that the terminal can accurately receive the auxiliary pilot channel according to the second configuration information, thereby acquiring the initial access information and/or the resynchronization information of the terminal in the auxiliary pilot channel, and reducing the time delay of the initial access and resynchronization of the terminal.

In the first transmission method (corresponding to the contents of one or two of the above-mentioned methods), when transmitting the auxiliary pilot information to the terminal through the auxiliary pilot channel, the first transmission frequency point and the first transmission time of the auxiliary pilot channel may be determined according to a frequency hopping frequency point for transmitting the auxiliary pilot channel and frequency hopping information of a serving cell of the terminal, which are configured in advance; the frequency hopping information is used for indicating frequency hopping points adopted in different times of a service cell of the terminal, and the frequency hopping information comprises: at least one of a system frame number and a system hyper frame number and a frequency hopping point list; and then, the auxiliary pilot frequency information is sent to the terminal at the first sending frequency point and the first sending time. In addition, the network device can also send the frequency hopping information to the terminal through the initial pilot frequency channel, and thus, the terminal can determine the first sending time and the first sending frequency point of the auxiliary pilot frequency channel through the frequency hopping information and the frequency hopping frequency point of the auxiliary pilot frequency channel, and receive the auxiliary pilot frequency information at the first sending time and the first sending frequency point, so that the terminal only needs to monitor the frequency hopping frequency point of the auxiliary pilot frequency channel when the network device uses the frequency hopping frequency point of the auxiliary pilot frequency channel, and the other times are in a power saving mode, thereby avoiding the situation that the terminal needs to continuously monitor the frequency hopping frequency point of the auxiliary pilot frequency channel, realizing that after the initial pilot frequency channel is detected, no frequency hopping frequency point needs to be monitored before the determined sending time of the auxiliary pilot frequency channel.

Specifically, a frequency hopping point list belongs to frequency hopping point information, and the frequency hopping point list is used for indicating a frequency hopping channel set of a system; the system frame number and the system superframe number belong to the frequency hopping time information, and specifically, when the repetition period of the frequency hopping pattern exceeds one superframe, the system superframe number can be included, and one superframe is 1024 radio frames. The system frame number is used to indicate the current radio frame number (0-1023), and the system superframe number (0-1023) is used to indicate that the current frame is located in a specific superframe of the frequency hopping pattern.

For the second transmission mode, that is, when the transmission period of the auxiliary pilot channel is a pre-configured period, the network device needs to transmit the frequency hopping information of the serving cell to the terminal in the initial pilot channel, so that the terminal determines the frequency hopping point used by the auxiliary pilot channel in each transmission period of the auxiliary pilot channel, thereby successfully receiving the auxiliary pilot information. The terminal can determine the specific sending process of the auxiliary pilot information through two specific carrying information of the initial pilot information. This is explained here.

The method comprises the steps that firstly, initial pilot frequency information comprises frequency hopping information of a service cell of a terminal, and the frequency hopping information is used for indicating frequency hopping frequency points adopted by the service cell of the terminal at different times; wherein the frequency hopping information includes: at least one of a system frame number and a system hyper frame number, and a list of hopping frequency points.

At this time, the auxiliary pilot channel and the data channel perform frequency hopping uniformly, so that a frequency hopping frequency point list in frequency hopping information carried by the initial pilot channel includes frequency point information of the pilot channel and the data channel, and when the network device sends the auxiliary pilot information to the terminal through the auxiliary pilot channel, the network device determines second sending time and a second frequency hopping frequency point of the auxiliary pilot channel according to the sending period of the auxiliary pilot channel and the uniform frequency hopping information of the service cell of the terminal; and transmitting the auxiliary pilot frequency information to the terminal at a second transmission time and a second frequency hopping frequency point.

In this way, the terminal determines a second sending frequency point and a second sending time of the auxiliary pilot channel through the unified frequency hopping information of the serving cell and the sending period of the auxiliary pilot channel, and receives the auxiliary pilot information at the second sending frequency point and the second sending time.

Secondly, the initial pilot frequency information comprises auxiliary pilot frequency channel frequency hopping information of a service cell of the terminal, and the auxiliary pilot frequency channel frequency hopping information is used for indicating frequency hopping frequency points adopted by the auxiliary pilot frequency channel of the service cell of the terminal at different times; wherein the auxiliary pilot channel hopping information includes: at least one of a system frame number and a system hyper frame number, and an auxiliary pilot channel frequency hopping frequency point list.

At this time, the auxiliary pilot channel and other channels (such as data channels) perform frequency hopping independently, so that the initial pilot channel only needs to carry frequency hopping information of the auxiliary pilot channel, and when the auxiliary pilot channel is sent to the terminal through the auxiliary pilot channel, the third sending time and the third frequency hopping point of the auxiliary pilot channel are determined according to the sending period of the auxiliary pilot channel and the independent frequency hopping information of the auxiliary pilot channel of the serving cell of the terminal relative to other channels; and transmitting the auxiliary pilot frequency information to the terminal at a third transmitting time and a third frequency hopping point.

In this way, the terminal determines the third sending frequency point and the third sending time of the auxiliary pilot channel according to the frequency hopping information of the auxiliary pilot channel and the sending period of the auxiliary pilot channel, and receives the auxiliary pilot information at the third sending frequency point and the third sending time.

It should be noted that the transmission period of the auxiliary pilot channel frequency point may be less than the duration of the frequency hopping frequency point. For example, the time occupied by each frequency hopping point is 80ms, the period of the auxiliary pilot channel frequency point is 20ms, the auxiliary pilot channel frequency point can be sent on each frequency hopping point 4 times, and a plurality of subframes can be repeated in each transmission.

In addition, specifically, a frequency hopping system usually employs a pseudo-random frequency hopping sequence, and repeats the frequency hopping sequence every k frequency hopping points, that is, repeats the former k frequency hopping points every k frequency hopping points, and the system repeats frequency hopping with the k frequency hopping points as a cycle, and the frequency hopping points of the k frequency hopping are frequency hopping patterns. A frequency hopping frequency point list in the frequency hopping information belongs to the frequency hopping frequency point information, and the frequency hopping frequency point list is used for indicating a frequency hopping channel set of the system; the system frame number and the system superframe number belong to the frequency hopping time information, and specifically, when the repetition period of the frequency hopping pattern exceeds one superframe, the system superframe number can be included, and one superframe is 1024 radio frames. The system frame number is used to indicate the current radio frame number (0-1023), and the system superframe number (0-1023) is used to indicate that the current frame is located in a specific superframe of the frequency hopping pattern.

It is noted that the network device determines according to the duration of the frequency point of the initial pilot channel and the repetition period of the frequency hopping pattern respectivelyThe number of bits used to signal the frame number and hyper-frame number. For example, if the duration of the initial pilot channel bin is 40ms, since the radio frame number occurring at the initial pilot channel bin must be a multiple of 4, only the upper 8 bits of the frame number need to be notified. The number of bits used to signal the frame number is: 10-log₂(DT), wherein DT is the duration of the initial channel frequency point in the unit of wireless frame. For example, if the repetition period of the system frequency hopping pattern is 8 superframes, since the terminal only needs to be notified of the offset position of the current frequency hopping point in the frequency hopping pattern, only the lower 3 bits of the superframe number need to be notified, and the other bits (i.e., the upper 7 bits) are transmitted in the auxiliary pilot channel or the data channel. Number of bits used to signal hyper frame number: log (log)₂(hopping _ pattern _ T), wherein hopping _ pattern _ T is a frequency hopping pattern repetition period in units of superframes.

In addition, specifically, the offset of the start time of the auxiliary pilot channel frequency point relative to the start time of the initial pilot channel frequency point is fixed. For example, assuming that the time offset of the auxiliary pilot channel frequency point relative to the initial position of the initial pilot channel frequency point is k (taking the radio frame as a unit), if the initial radio frame number of the initial pilot channel frequency point is n, the radio frame number of the position where the auxiliary pilot channel frequency point appears is (n + k) mod 1024, and the auxiliary pilot channel frequency point appears with t as a cycle. Specifically, the auxiliary pilot channel bin starts to transmit in the next radio frame after the duration of the initial pilot channel bin ends.

Of course, it should be noted herein that when the auxiliary pilot channel and the initial pilot channel appear at the same time in a preconfigured period, and the second target frequency hopping frequency point of the auxiliary pilot channel is the same as the first target frequency hopping frequency point of the initial pilot channel, the network device sends the initial pilot channel (does not send the auxiliary pilot channel), or sends the auxiliary pilot channel after sending the initial pilot channel.

The initial pilot frequency information comprising the synchronous signal is sent to the terminal through the initial pilot frequency channel, and the auxiliary pilot frequency information comprising the terminal initial access information and/or the resynchronization information is sent to the terminal through the auxiliary pilot frequency channel, so that the initial access terminal can perform initial synchronization according to the received initial pilot frequency information and perform initial access according to the initial access information in the auxiliary pilot frequency information, and the initial access time delay of the initial access terminal is reduced; in addition, the resynchronization terminal can perform resynchronization through the initial pilot channel or the auxiliary pilot channel, and the resynchronization time delay of the resynchronization terminal is reduced.

As shown in fig. 5, an embodiment of the present invention provides a method for transmitting pilot information, which is applied to a terminal in a frequency hopping communication system, where the frequency hopping communication system is configured with an initial pilot channel and an auxiliary pilot channel, and frequency hopping points of the initial pilot channel are different from frequency hopping points of the auxiliary pilot channel, and the method includes:

step 501: initial pilot information is received over an initial pilot channel.

In this step, specifically, the terminal receives the initial pilot information through the initial pilot channel. Wherein, the initial pilot frequency information includes a synchronous signal. Therefore, the initial pilot information comprises the synchronization signal, so that the terminal can perform initial synchronization or resynchronization according to the synchronization signal.

In addition, specifically, when the initial pilot information is received through the initial pilot channel, the initial pilot information may be received through a first target frequency hopping point of the initial pilot channel; the first target frequency hopping frequency point is determined from first frequency hopping frequency points configured in advance; or the first target frequency hopping frequency point is determined from the pre-configured first frequency hopping frequency points according to the Physical Cell Identifier (PCI) of the service cell of the terminal; the first frequency hopping frequency point is a pre-configured pilot frequency channel frequency point.

Step 502: the secondary pilot information is received over a secondary pilot channel.

In this step, specifically, the terminal receives the auxiliary pilot information through the auxiliary pilot channel. The auxiliary pilot information includes terminal initial access information and/or resynchronization information.

Therefore, the initial access information and/or the resynchronization information are received through the auxiliary pilot frequency channel, so that the initial access terminal can perform initial access according to the initial access information, the initial access time delay is reduced, and the terminal needing resynchronization can perform resynchronization through the resynchronization information, so that the terminal resynchronization time delay is reduced, and the problems that the pilot frequency channel period in an NB-IoT-U system is too long, and the initial access time of the terminal and the terminal synchronization time are increased are solved.

Therefore, the embodiment of the invention receives the initial pilot frequency information through the initial pilot frequency channel, the initial pilot frequency information comprises the synchronous signal, and receives the auxiliary pilot frequency information through the auxiliary pilot frequency information, the auxiliary pilot frequency information comprises the terminal initial access information and/or the resynchronization information, so that in an NB-IoT-U system, the initial access terminal can realize the initial synchronization of the terminal through the synchronous signal in the initial pilot frequency information, and the initial access information is obtained through the auxiliary pilot frequency information, thereby reducing the initial access time delay of the terminal; in addition, the terminal needing resynchronization can perform resynchronization through the initial pilot channel or the auxiliary pilot channel, thereby reducing the resynchronization delay of the terminal.

Further, in the embodiment of the present invention, the auxiliary pilot channel may have multiple transmission modes, and the initial pilot information received through the initial pilot channel may be different in accordance with different transmission modes. This is described in detail below.

the first mode is as follows: the sending frequency point of the auxiliary pilot channel is a pre-configured frequency hopping frequency point, that is, the frequency hopping frequency point selectable by the auxiliary pilot channel is fixed, as shown in fig. 3, which is a schematic diagram when the sending frequency point of the auxiliary pilot channel is pre-configured. In fig. 3, since the system randomly hops to the hopping frequency point of the secondary pilot channel within the time of completing one hopping pattern, the period of occurrence of the secondary pilot channel may not be fixed.

The second mode is as follows: the transmission period of the auxiliary pilot channel is a pre-configured period, that is, the transmission period of the auxiliary pilot channel is fixed. Fig. 4 is a schematic diagram of the periodic transmission of the auxiliary pilot channel. In fig. 4, since the system randomly hops to the hopping frequency point of the auxiliary pilot channel within the time of completing one hopping pattern, the hopping frequency point occurring in the auxiliary pilot channel may not be fixed.

In the frequency hopping system, when the number of all frequency hopping points preconfigured by the system is more than that of actually adopted frequency hopping points, the terminal is generally informed of a frequency hopping point list specifically adopted by the system. Specifically, the terminal obtains the frequency hopping frequency point list adopted by the system by receiving initial pilot frequency information in an initial pilot frequency channel. In addition, specifically, since the initial pilot channel frequency point belongs to a frequency hopping frequency point, the initial pilot channel frequency point must belong to a system frequency hopping frequency point list. In the case that the network device indicates the frequency hopping set used by the system in the channel group mode, for example, if the frequency band from 902MHz to 928MHz of the FCC is divided into 128 200KHz frequency points and 128 channels are divided into 32 channel groups, the network device may send a frequency point list with 32 bit values, where each bit represents whether the corresponding channel group belongs to the system frequency hopping set (for example, 1 represents that the corresponding channel group belongs to the frequency hopping set and 0 represents that the corresponding channel group does not belong to the frequency hopping set), and if the number of frequency hopping frequencies of the system is required to be 64, the frequency point list needs to include 16 channel groups. The channel group to which the initial pilot channel bin belongs must be included in the channel group informed by the bin list.

The following describes the receiving procedure of the secondary pilot channel and the initial pilot information in detail for different transmission modes of the secondary pilot channel.

Firstly, when auxiliary pilot frequency information is received through an auxiliary pilot frequency channel, the auxiliary pilot frequency information is received through a second target frequency hopping point of the auxiliary pilot frequency channel; the second target frequency hopping frequency point is determined from the second frequency hopping frequency points which are configured in advance; or the second target frequency hopping frequency point is determined from the second frequency hopping frequency points which are configured in advance according to the PCI of the service cell of the terminal; or the second target frequency hopping frequency point is determined from all the pre-configured frequency hopping frequency points; or the second target frequency hopping frequency point is determined from all the pre-configured frequency hopping frequency points according to the PCI of the service cell of the terminal; the second frequency hopping frequency point is a pre-configured pilot frequency channel frequency point; all frequency hopping frequency points comprise data channel frequency points and pre-configured pilot frequency channel frequency points.

At this time, in one aspect, the initial pilot information further includes first configuration information used for indicating a second target frequency hopping point of the auxiliary pilot channel, and if the second target frequency hopping point is determined from second frequency hopping points configured in advance, the first configuration information includes at least one of the following:

Therefore, when the second target frequency point of the auxiliary pilot channel is selected from the second frequency hopping frequency points which are configured in advance and belong to the pilot channel frequency points, the terminal can accurately receive the auxiliary pilot channel according to the first configuration information by receiving the first configuration information comprising at least one item, so that the initial access information and/or the resynchronization information of the terminal in the auxiliary pilot channel are obtained, and the time delay of the initial access and resynchronization of the terminal is reduced.

Secondly, the initial pilot frequency information further includes second configuration information for indicating a second target frequency hopping point of the auxiliary pilot frequency channel, and when the second target frequency hopping point is determined from all the pre-configured frequency hopping points, the second configuration information includes at least one of the following:

Therefore, when the second target frequency point of the auxiliary pilot channel is selected from all the pre-configured frequency hopping frequency points, the terminal can accurately receive the auxiliary pilot channel according to the second configuration information by receiving the second configuration information comprising at least one item, so that the initial access information and/or the resynchronization information of the terminal in the auxiliary pilot channel are obtained, and the time delay of the initial access and the resynchronization of the terminal is reduced.

In the first transmission scheme (corresponding to the first and second transmission schemes), when the terminal receives the frequency hopping information of the serving cell from the initial pilot channel and receives the auxiliary pilot information through the auxiliary pilot channel, the terminal may receive the auxiliary pilot information at the first transmission frequency point and the first transmission time of the auxiliary pilot channel; the first sending frequency point and the first sending time are determined according to a pre-configured frequency hopping frequency point for sending an auxiliary pilot channel and frequency hopping information of a service cell of the terminal; the frequency hopping information is used for indicating frequency hopping points adopted in different times in a service cell of the terminal, and the frequency hopping information comprises: at least one of a system frame number and a system hyper frame number, and a list of hopping frequency points. Therefore, the auxiliary pilot frequency information is received at the determined first sending frequency point and the first sending time, so that the terminal only needs to monitor the frequency hopping frequency point of the auxiliary pilot frequency channel when the network equipment uses the frequency hopping frequency point of the auxiliary pilot frequency channel, and the terminal is in a power-saving mode at other times, thereby avoiding the situation that the terminal needs to continuously monitor the frequency hopping frequency point of the auxiliary pilot frequency channel, realizing that after the initial pilot frequency channel is detected, no frequency hopping frequency point needs to be monitored before the sending time of the determined auxiliary pilot frequency channel, and saving the power consumption of the terminal.

For the second transmission mode, that is, when the transmission period of the auxiliary pilot channel is a pre-configured period, the specific transmission process of the auxiliary pilot information may be determined by distinguishing the specific carried information of the initial pilot information. This is explained here.

The initial pilot frequency information also comprises frequency hopping information of a service cell of the terminal, and the frequency hopping information is used for indicating frequency hopping frequency points adopted by the service cell of the terminal at different times; wherein the frequency hopping information includes: at least one of a system frame number and a system hyper frame number, and a list of hopping frequency points.

At this time, the auxiliary pilot channel and the data channel perform frequency hopping uniformly, so that a frequency hopping frequency point list in frequency hopping information contained in the initial pilot channel includes frequency point information of the pilot channel and the data channel, and when the terminal receives the auxiliary pilot information through the auxiliary pilot channel, the terminal receives the auxiliary pilot information at a second sending time and a second frequency hopping frequency point of the auxiliary pilot channel; and the second sending time and the second frequency hopping frequency point of the auxiliary pilot channel are determined according to the sending period of the auxiliary pilot channel and the frequency hopping information of the service cell of the terminal.

At this time, the auxiliary pilot channel and other channels (such as data channels) perform frequency hopping independently, so that the initial pilot channel only needs to carry frequency hopping information of the auxiliary pilot channel, and when the auxiliary pilot channel receives the auxiliary pilot information, the auxiliary pilot information can be received at a third sending time and a third frequency hopping frequency point of the auxiliary pilot channel; and the third sending time and the third frequency hopping point of the auxiliary pilot channel are determined according to the sending period of the auxiliary pilot channel and independent frequency hopping information of the auxiliary pilot channel of the service cell of the terminal relative to other channels.

The embodiment of the invention receives initial pilot frequency information through an initial pilot frequency channel, the initial pilot frequency information comprises a synchronous signal, and receives auxiliary pilot frequency information through the auxiliary pilot frequency information, the auxiliary pilot frequency information comprises terminal initial access information and/or resynchronization information, so that in an NB-IoT-U system, the initial access terminal can realize the initial synchronization of the terminal through the synchronous signal in the initial pilot frequency information, and the initial access information is obtained through the auxiliary pilot frequency information, thereby reducing the initial access time delay of the terminal; in addition, the terminal needing resynchronization can perform resynchronization through the initial pilot channel or the auxiliary pilot channel, thereby reducing the resynchronization delay of the terminal.

The terminal in the embodiment of the present invention may be a mobile phone (or a mobile phone), or other devices capable of sending or receiving wireless signals, including a user equipment (terminal), a Personal Digital Assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a Wireless Local Loop (WLL) station, a CPE or Mifi capable of converting a mobile signal into a wifi signal, an intelligent appliance, or other devices capable of autonomously communicating with a mobile communication network without human operation, and the like.
