Detailed Description

In the prior art, the SSB transmission period is typically 20ms, and the receiving position of the SSB is typically located at the end of the SSB transmission period. According to the existing processing mode, after the terminal equipment is awakened, the synchronous signal block is received first, and the time frequency offset information carried in the synchronous signal block is obtained. Based on the time-frequency offset information, time-frequency synchronization is completed. After synchronization is completed, a paging message is received.

As shown in fig. 2, a schematic diagram of a wake-up time of a terminal device is given.

In fig. 2, the terminal device receives the synchronization signal block immediately after being awakened, and sets the transmission period of the synchronization signal block to 20ms. The terminal equipment analyzes the received synchronous signal block, and the required duration is Tssb. After the analysis of the synchronous signal block is completed, the paging message is monitored and received. Then, the duration interval from the completion of receiving the synchronization signal block to the completion of receiving the paging message by the terminal device is (Tssb, tssb+20) ms.

It can be seen that after the terminal device is awakened, from receiving the synchronization signal block to receiving the paging message, an average duration of more than 10ms is required, resulting in higher power consumption of the terminal device.

In the embodiment of the invention, when the paging occasion corresponding to the paging message is at least partially overlapped with the transmission period of the synchronous signal block, the paging message can be received and stored. And acquiring time frequency offset information from a synchronous signal block transmitted in a synchronous signal transmission period, and analyzing the paging message based on the time frequency offset information. Therefore, the time that the terminal equipment is in the wake-up state can be greatly reduced, and the power consumption of the terminal equipment is reduced.

The chip system may include a chip and may also include other discrete devices.

The embodiment of the invention provides an information acquisition method, and the detailed description is given below through specific steps with reference to fig. 1.

Step 101, receiving and saving paging message.

In the embodiment of the invention, the terminal equipment can acquire the paging occasion for receiving the paging message. If the paging occasion at least partially overlaps with the synchronization signal block transmission period, a paging message may be received at the paging occasion.

In an implementation, if the paging occasion is before the reception position of the synchronization signal block, the terminal device may receive the paging message at the paging occasion. The terminal device may save the received paging message.

In the embodiment of the invention, if the terminal equipment detects that the following conditions are met, the paging message can be received and stored: the k0 corresponding to the paging message satisfies the first condition, and the beam satisfies the second condition. The beams described above may be used to transmit synchronization signal blocks.

Specifically, the satisfaction of k0 corresponding to the paging message to the first condition may mean that: the value range of k0 only contains a fixed value, or the value range of k0 is 0 or 1, where k0 may refer to the number of time slots between the physical downlink control channel (Physical Downlink Control Channel, PDCCH) and the physical downlink shared channel (Physical Downlink shared Channel, PDSCH) corresponding to the paging message.

As known from the existing protocol, when the PDSCH time domain resource (time domain resource) adopts Default (Default) a, default B or Default C, the value of k0 is 0.

When the time domain allocation list (time domain allocation list) is configured in the system message block 1 (SIB 1), the value of k0 corresponding to the paging message includes all values in the time domain allocation list. In the existing protocol, the value range of k0 corresponding to the paging message has a large probability of one value.

It will be appreciated that as the communication protocol evolves further, the first condition described above may also be updated to: the value of k0 is smaller than or equal to N, and N is a positive integer.

In a specific implementation, the terminal device may measure each beam configured by the serving cell, to obtain a measurement result corresponding to each beam. The serving cell is a cell in which the terminal device currently resides, and may configure one or more beams for the terminal device.

In the embodiment of the invention, the terminal equipment detects that the wave beam meets the second condition, which means that the signal quality of the wireless environment where the terminal equipment is currently located is better, and/or the wave beam measurement result has smaller fluctuation in a period of time.

In implementations, the synchronization signal blocks may be in a one-to-one correspondence with the beams. For example, the serving cell in which the terminal device currently resides has 4 synchronization signal blocks, SSB1 to SSB4, respectively. Accordingly, there are 4 beams, respectively beam 1-beam 4, in the serving cell. SSB1 corresponds to beam1, SSB2 corresponds to beam2, SSB3 corresponds to beam3, and SSB4 corresponds to beam4.

In a specific implementation, the terminal device may obtain a sliding average value of signal-to-noise ratios of beams corresponding to all synchronization signal blocks in a first period of time before the current paging occasion. If the moving average value of the signal to noise ratios of the beams corresponding to all the synchronous signal blocks in the first time period is larger than the preset threshold THsnr, it can be determined that the signal quality of the wireless environment where the terminal equipment is currently located is better, and therefore it can be determined that the beams meet the second condition.

Specifically, the duration of the first period may be set according to an actual application scenario, an application requirement, and the like.

In some embodiments, the terminal device may obtain a running average of the signal-to-noise ratios of all beams obtained for the first K measurement periods. If the signal-to-noise ratio sliding average value of all beams obtained in the first K measuring periods is larger than a preset threshold THsnr, the terminal equipment receives and stores the paging message. K is a positive integer.

For example, the terminal device may obtain a sliding average of the signal-to-noise ratios of all beams obtained in the previous measurement period. If the signal-to-noise ratio sliding average value of all beams obtained in the last measurement period is larger than the preset threshold THsnr, the terminal equipment receives and stores the paging message.

In a specific implementation, the terminal device may acquire the number of the beams obtained by measurement in a second period of time before the current paging occasion. If only one beam is detected within a second time period prior to the current paging occasion, it may be determined that the beam satisfies a second condition. The duration of the second period of time may be set according to an actual application scenario, an application requirement, and the like.

In a specific implementation, the terminal device may acquire the number of beams obtained by measurement in a third period of time before the paging occasion. In a third time period before the paging occasion, detecting that N wave beams exist, wherein the signal-to-noise ratio change degree of the first M wave beams with the largest signal-to-noise ratio in the N wave beams is smaller than a preset change degree threshold, and the signal-to-noise ratio of the first wave beam and the second wave beam in the N wave beams is larger than the preset threshold, and determining that the paging message can be received and stored. M and N are positive integers.

In the embodiment of the invention, the signal-to-noise ratio variation degree can be represented by a signal-to-noise ratio variation amount or a signal-to-noise ratio variation rate. The degree of signal-to-noise ratio variation may reflect fluctuations in the signal-to-noise ratio of a certain beam over a period of time. When the signal-to-noise ratio variation degree is smaller than a preset variation degree threshold, the wireless environment where the terminal equipment is located can be represented to be stable.

In some embodiments, for a certain beam, the corresponding signal-to-noise ratio variation is characterized by a signal-to-noise ratio variation, where the signal-to-noise ratio variation is: the difference between the maximum signal-to-noise ratio and the minimum signal-to-noise ratio of the beam during the third time period.

If the signal-to-noise ratio variation is represented by the signal-to-noise ratio variation, the signal-to-noise ratio variation being smaller than the preset variation threshold may mean that: and in the third time period, the difference between the maximum signal-to-noise ratio and the minimum signal-to-noise ratio of the beam is not greater than a preset difference threshold.

The difference threshold may be set according to a specific application scenario. For example, in one embodiment, the difference threshold may be 2dBm. In another embodiment, the difference threshold may be 4dBm.

In other embodiments, for a certain beam, the corresponding signal-to-noise ratio change degree is represented by a signal-to-noise ratio change rate, where the signal-to-noise ratio change rate is: the difference between the maximum signal-to-noise ratio and the minimum signal-to-noise ratio of the beam over the third time period is divided by the running average of the signal-to-noise ratios of the beam over the third time period.

If the signal-to-noise ratio variation is represented by a signal-to-noise ratio variation rate, the signal-to-noise ratio variation being smaller than the preset variation threshold may mean that: and in the third time period, the signal-to-noise ratio change rate of the beam is larger than a preset change rate threshold.

The change rate threshold may also be set according to a specific application scenario. For example, in one embodiment, the rate of change threshold is 20%. In another embodiment, the rate of change threshold is 30%.

In an implementation, the first beam may be a beam with the greatest signal-to-noise ratio of the N beams. The second beam may be the beam with the greatest signal-to-noise ratio before the maximum signal-to-noise ratio changes.

In some embodiments, the wireless environment in which the terminal device is located may change over a period of time, resulting in a change in the beam with the greatest signal-to-noise ratio. For example, during a period of time, the terminal device is in a low-speed moving state, and the beam with the maximum signal-to-noise ratio is changed from beam2 to beam 1. In this scenario, beam2 is the beam with the greatest signal-to-noise ratio (i.e., the second beam) before the beam with the greatest signal-to-noise ratio changes, and beam1 is the beam with the greatest current signal-to-noise ratio (i.e., the first beam).

In an implementation, if 1 < N < 4, the value of M may be 1.

That is, in the third period before the paging occasion, if the terminal device detects 2 beams or 3 beams, and the moving average of the change rate of the beam with the largest signal-to-noise ratio is smaller than the preset change rate threshold, and the signal-to-noise ratio of the first beam and the signal-to-noise ratio of the second beam are both larger than the preset threshold, it may be determined that the beams satisfy the second condition.

For example, in a third time period before the paging occasion, the terminal device detects that there are 2 beams, beam1 and beam2 in sequence, and before the first time in the third time period, the signal-to-noise ratio of beam1 is greater than the signal-to-noise ratio of beam 2. After a first time in the third time period, the signal-to-noise ratio of beam2 is greater than the signal-to-noise ratio of beam 1. In the last measurement, the signal-to-noise ratio of the beam1 and the signal-to-noise ratio of the beam2 are both greater than a preset threshold, and the moving average of the change rate of the beam2 is smaller than the preset change rate threshold. Thus, it is determined that the beam measurement of the terminal device fluctuates less over a period of time, i.e. the beam is in a more stable state.

In the specific implementation, if N is more than or equal to 4 and less than or equal to 8, the value of M can be 1 or 2.

For example, in a third time period before the paging occasion, the terminal device detects that there are 4 beams, in turn, beam1 to beam4, and before the first time in the third time period, the signal-to-noise ratio of beam1 is maximum. After the first time in the third time period, the signal-to-noise ratios of the four beams are sequentially as follows: beam2, beam1, beam3, beam4. In the last measurement, the signal to noise ratio of the beam1 and the beam2 are both larger than a preset threshold, and the moving average of the change rates of the beam1 and the beam2 is smaller than the preset change rate threshold. Thus, it is determined that the beam measurement of the terminal device fluctuates less over a period of time, i.e. the beam is in a more stable state.

In the embodiment of the invention, the terminal equipment can save all paging messages of which the paging occasions at least partially overlap with the transmission period of the synchronous signal block. Or, the terminal device may only store the paging message corresponding to the first synchronization signal block, where the first synchronization signal block is the synchronization signal block corresponding to the beam with the largest signal-to-noise ratio obtained by the last measurement.

Specifically, the number of paging messages in which the paging occasion and the transmission period of the synchronization signal block at least partially overlap may be multiple, and each of the paging messages corresponds to a different beam, that is, each of the synchronization signal blocks. In this scenario, the terminal device may compare the signal-to-noise ratios corresponding to the different beams, and only save the paging message corresponding to the beam with the largest signal-to-noise ratio.

For example, there is an overlap of the paging occasion of paging message 1 with synchronization signal block transmission period 1, and the paging occasion of paging message 2 with synchronization signal block transmission period 2. The synchronization signal block transmission period 1 transmits the synchronization signal block 1, and the synchronization signal block transmission period 2 transmits the synchronization signal block 2. Synchronization signal block 1 corresponds to beam1 and synchronization signal block 2 corresponds to beam 2. The signal-to-noise ratio of beam1 is greater than the signal-to-noise ratio of beam2, paging message 2 is received and stored.

Step 102, receiving the synchronization signal block transmitted in the synchronization signal block transmission period.

In a specific implementation, after the terminal device is awakened, the synchronization signal block sent by the network device may be received in a synchronization signal block transmission period. The terminal equipment can analyze the synchronous signal block and acquire the time frequency offset information from the synchronous signal block.

Specifically, the specific process of the terminal device obtaining the synchronization signal block and the process of the terminal device analyzing the synchronization signal block may refer to the prior art, which will not be described herein.

And 103, analyzing the paging message based on the time-frequency offset information carried in the synchronous signal block.

And acquiring time frequency offset information from a synchronous signal block transmitted in a synchronous signal transmission period, and analyzing the paging message based on the time frequency offset information. Therefore, the time that the terminal equipment is in the wake-up state can be greatly reduced, and the power consumption of the terminal equipment is reduced.

In the embodiment of the invention, because the time-frequency synchronization is not performed when the paging message is received, the corresponding redundant time can be added to the paging frame corresponding to the paging message, thereby ensuring that the boundary of the paging frame can be accurately acquired after the time-frequency offset information is acquired.

In a specific implementation, a first redundancy time may be set before the PDCCH corresponding to the paging message, and a second redundancy time may be set after the PDSCH corresponding to the paging message, where a time domain end position of the first redundancy time may be a time domain start position of the PDCCH, and a time domain start position of the second redundancy time may be a time domain end position of the PDSCH.
