Description

An adaptive waveform transmission method, device and system

technical field

The present invention relates to the technical field of wireless communication, in particular to an adaptive waveform transmission method, device and system.

Background technique

In order to meet people's increasing demand for high-speed data service transmission, and considering that the intersymbol interference suppression algorithm introduced by multi-path channels in single-carrier equalization technology is relatively complex, multi-carrier technology is widely used in high-speed broadband multimedia services in transit. Existing multi-carrier technologies may include OFDM (Orthogonal Frequency Division Multiplexing, Orthogonal Frequency Division Multiplexing), GFDM (Generalized Frequency Division Multiplexing, Generalized Frequency Division Multiplexing), F-OFDM (Filtered OFDM, filtered Orthogonal Frequency Division Multiplexing) technology), UFMC (Univeral Filtered Multi-Carrier, universal filter multi-carrier) and FBMC (Filter Bankbased Multi-Carrier, multi-carrier based on filter bank), among them, since OFDM uses a set of orthogonal subcarrier multi-carrier Parallel transmission of business data, and can be realized by using fast FFT (Fast Fourier Transformation, Fast Fourier Transformation)/IFFT (Inverse FFT Transformation) algorithm, so it is widely used in broadband wireless communication systems, such as LTE (LongTerm Evolution, long-term evolution) Both the system and WIFI (Wireless-Fidelity, wireless fidelity) use OFDM as a key technology of the physical layer.

In the fifth-generation mobile communication system in the future, in addition to continuing to enhance the performance of mobile broadband services, it is also necessary to meet the diverse scenarios of the Internet of Things in the future, such as ultra-large capacity, ultra-low latency, ultra-high-speed mobility, and ultra-large connections. . However, in the existing LTE system, if the OFDM waveform transmission method is used for signaling transmission, the corresponding configuration is that the subcarrier spacing is uniformly 15KHz, and the transmission time interval is 1ms, so the OFDM waveform transmission method configured in the LTE system is not suitable for ultra-low latency. Transmission of business. In addition, because the system using the OFDM waveform transmission method is susceptible to the influence of frequency offset and has high requirements for signal synchronization, the system performance will suffer a large loss in high-speed mobile and other scenarios with large frequency offset. Other waveform transmission methods suitable for ultra-low-latency services or high-speed mobile scenarios should be selected, but the applicant found that the waveform transmission method designed by the existing LTE system cannot adaptively configure the waveform transmission method according to the current transmission scenario of the terminal.

For example, in the existing LTE/LTE-A (LTE-Advanced, evolution of LTE) system, if OFDM is used as the waveform transmission scheme, the terminal returns to the RRC (Radio Resource Control, radio resource control) idle state from power-on to the end The process is roughly as follows: when the terminal is turned on, it will perform frequency point scanning, cell search and synchronization, system information acquisition, PLMN selection, cell selection and reselection, and finally reside in a certain cell. After a series of operations, enter RRC idle state. Furthermore, the process of the terminal returning to the RRC idle state from the RRC connection state is roughly as follows: when there is a terminal service on the network side or the terminal itself needs to initiate a service, the terminal will initiate the RRC connection establishment process, and the terminal will initiate a random access establishment process. After the RRC connection and radio bearer, when it is necessary to send data, if there are resources allocated by the base station, the allocated resources can be directly used for data transmission; if there are no resources available for transmission, the resources need to be allocated through the scheduling request process After the application, the resources obtained by the application are used to finally complete the data transmission. After that, when the terminal needs to release the connection due to some reasons, such as transmission completion or load balancing, the terminal will return from the RRC connection state to the RRC idle state. .

The applicant found in the process of researching the above-mentioned process (from powering on the terminal to returning to the RRC idle state and from establishing the RRC connection to disconnecting the RRC connection) that in the above-mentioned process, the terminal can only transmit the waveform according to the current default configuration For signaling transmission, it is impossible to adaptively configure related waveform transmission schemes according to different transmission scenarios required by the terminal. Therefore, the waveform transmission mode configured in the existing LTE system cannot meet the needs of diversified extreme scenarios of the fifth-generation mobile communication technology in the future.

Therefore, it is urgent to provide a new waveform transmission method to solve the problem that in the existing LTE system, the terminal can only perform signaling transmission according to the current default waveform transmission mode, and cannot adaptively configure related waveforms according to different transmission scenarios. The transmission scheme leads to the problem that it cannot meet the diversified scene requirements of the fifth-generation mobile communication technology in the future.

Detailed ways

In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Embodiment one:

Embodiment 1 of the present invention provides an adaptive waveform transmission method, which is applicable to a filter bank multi-carrier system, as shown in FIG. 1 , which is the flow of the adaptive waveform transmission method described in Embodiment 1 of the present invention Schematically, the method may include the following steps:

Step 101: the base station determines the transmission scene information where the terminal is currently located, where the transmission scene information refers to information indicating network performance status.

It should be noted that the network performance status can be represented by high latency, slow movement, small capacity, low latency, high speed mobility, or large capacity. Therefore, different network performance states can be represented by different transmission scene information. The embodiment of the invention does not repeat this.

Step 102: According to the determined transmission scene information where the terminal is currently located, configure terminal frame structure configuration information corresponding to the current transmission scene information of the terminal and representing a waveform transmission mode.

Step 103: Send a waveform type indication parameter carrying the terminal frame structure configuration information to the terminal, so as to be represented by the terminal frame structure configuration information in the waveform type indication parameter received by the terminal Waveform transmission mode for signaling transmission.

That is to say, in the technical solutions described in the embodiments of the present invention, the base station can adaptively configure a waveform transmission scheme that is suitable for the current transmission scenario of the terminal according to the current transmission scenario of the terminal, so as to meet the needs of future fifth-generation mobile Diversified scene requirements of communication technology improve user experience.

Optionally, in step 101, the base station may, according to the channel environment where the terminal is located, the service type of the terminal, the communication type of the terminal, the processing capability of the terminal, QoS (Quality of Service, quality of service), QoE (Quality of Experience, quality of experience) or terminal One or more of the functions and other information determines the current transmission scene information of the terminal, which is not limited in this embodiment of the present invention.

Further, an example is used to illustrate that in step 102, according to the determined current transmission scene information of the terminal, terminal frame structure configuration information corresponding to the current transmission scene information of the terminal and representing a waveform transmission mode is configured.

For example, when the terminal works in the current LTE frequency band, the communication type is TDD (Time Division Duplexing, time division duplex)/FDD (Frequency Division Dual, frequency division duplex) duplex mode, the processing capacity meets the current LTE definition index, and the service type is For typical mobile Internet services, and the channel environment is a typical urban microcell, the base station can determine that the current network performance status required by the terminal is a high-capacity transmission state, that is, the base station can determine that the current transmission scenario of the terminal is high-capacity based on the above information of the terminal In the transmission scenario, at this time, the terminal frame structure configuration information may be configured as the terminal frame structure configuration information representing the OFDM waveform transmission mode.

For another example, when the terminal works in the current LTE frequency band, the communication type is TDD/FDD/multi-mode duplex, the processing capacity is higher than the current LTE definition index, and the service type is future Internet of Things services (for example: with massive connections, small data, etc. characteristics), and the channel environment is quasi-stationary, the base station can determine that the current network performance state required by the terminal is a slow mobile transmission state, that is, the base station can determine that the current transmission scene of the terminal is a slow mobile transmission scene according to the above information of the terminal , at this time, the configurable terminal frame structure configuration information is terminal frame structure configuration information representing a Filtered-OFDM (F-OFDM) waveform transmission mode. Furthermore, if other factors are considered comprehensively, such as high frequency band, cost, implementation complexity, and performance requirements, etc., in this example, the terminal frame structure configuration information can also be configured as the terminal frame structure configuration information representing the GFDM or UFMC waveform transmission mode. The embodiment of the invention does not repeat this.

In addition, the terminal frame structure configuration information may at least include: the number of subcarriers, the number of symbols, the number of sampling points for each symbol, the number of subsymbols, and the number of sampling points for each subsymbol, etc., that is, through these terminal frame structure configurations The information can know the waveform transmission mode it represents, and then the terminal can transmit related signaling according to the corresponding waveform transmission mode.

Specifically, when the base station selects different waveform transmission modes to configure the corresponding terminal frame structure configuration information, it can be configured according to the following design principles:

1. According to the terminal processing capability (that is, the implementation complexity) from large to small, the sequence of waveform transmission methods can be arranged as FBMC>GFDM>Filtered-OFDM>UFMC>OFDM.

2. According to the type of terminal service, for example, when low latency is required, the symbol length in the terminal frame structure configuration information can be configured to be longer; when high latency is required, the symbol length in the terminal frame structure configuration information can be configured to be short.

3. According to the channel environment of the terminal, if the channel environment is quasi-stationary, the subcarrier width in the terminal frame structure configuration information can be configured to be narrow; when the channel environment is high-speed transmission, the subcarriers in the terminal frame structure configuration information can be configured Wider width.

Of course, the design principles of the terminal frame structure configuration information are not limited to the above three points, and may also be designed according to the actual conditions of the terminal and the channel, etc., which will not be described in this embodiment of the present invention.

Further, before sending the waveform type indication parameter carrying the terminal frame structure configuration information to the terminal, the method may further include:

According to the current transmission scene information of the terminal, the terminal is divided into a set corresponding to the current transmission scene information of the terminal.

The advantage of this is that the waveform transmission modes of multiple terminals can be configured at the same time, which reduces signaling overhead. It should be noted that the division of each terminal set here is a virtual division, not necessarily divided according to the physical terminal type, and the terminals divided in each set will be changed according to the current transmission scene information of each terminal itself. , which will not be described in detail in this embodiment of the present invention.

Correspondingly, after the terminal is divided into a set corresponding to the current transmission scene information of the terminal, step 103 sends to the terminal a waveform type indication parameter carrying the configuration information of the terminal frame structure, which may be The specific implementation is:

Sending the waveform type indication parameter carrying the terminal frame structure configuration information to all the terminals in the set to which the terminal belongs.

Further, when sending the waveform type indication parameter carrying the terminal frame structure configuration information to the terminal, different signaling transmission procedures may be selected to transmit the waveform type indication parameter according to the current transmission scene information of the terminal, Specifically, the following five methods can be included:

Way 1: Carry the waveform type indication parameter in system information reconfiguration signaling and send it to the terminal.

Specifically, the waveform type indication parameter may be carried in the system information reconfiguration signaling and sent to the terminal by initiating the system information reconfiguration signaling. It should be noted that the configuration period of this signaling transmission process is relatively long, generally at the level of hundreds of milliseconds. For example, when the transmission scene information of the terminal does not require high delay and the required signaling overhead is small, this method can be selected. The transmit waveform type indicates the parameter.

Mode 2: Carry the waveform type indication parameter in the RRC reconfiguration signaling and send it to the terminal.

Mode 3: Carry the waveform type indication parameter in the MAC layer control unit signaling in the MAC header and send it to the terminal.

It should be noted that the configuration period of the signaling transmission process is generally tens of milliseconds.

Way 4: Carry the waveform type indication parameter in the control signaling of the physical layer channel and send it to the terminal.

It should be noted that the configuration period of this signaling transmission process is relatively short, generally at the level of several milliseconds, and has good adaptability. When the transmission scene information of the terminal has high requirements on delay, this method can be selected to transmit the waveform type indication parameter.

Method 5. This method is the signaling transmission process applicable when the terminal needs to use a waveform transmission method different from the current default configuration according to its current transmission scene information, and actively applies to the base station to modify the waveform transmission method. Specifically, it can be implemented as follows:

receiving the RRC reconfiguration signaling sent by the terminal, where the RRC reconfiguration signaling carries a waveform transmission mode identifier corresponding to the current transmission scene information of the terminal;

According to the waveform transmission mode identifier, configure terminal frame structure configuration information corresponding to the waveform transmission mode identifier and representing the waveform transmission mode.

Afterwards, the base station sends the waveform type indication parameter carrying the configuration information of the terminal frame structure to the terminal.

For example, assume that the current default waveform transmission mode of the terminal is OFDM waveform transmission mode, but the terminal needs to change the current default configuration of OFDM waveform transmission mode to GFDM waveform transmission mode according to the current transmission scene information of the terminal, such as the current service type of the terminal, etc. , to meet the resources required by the current service of the terminal. At this time, the terminal can send the RRC reconfiguration signaling carrying the GFDM waveform transmission mode identifier to the base station, and the base station receives the RRC reconfiguration signaling, and according to the RRC reconfiguration signaling The GFDM waveform transmission mode identifier in , configure the terminal frame structure configuration information corresponding to the GFDM waveform transmission mode identifier and represent the GFDM waveform transmission mode, and then send the waveform carrying the terminal frame structure configuration information to the terminal The type indicates the parameter.

It should be noted that the waveform type indication parameter may be carried in the RRC reconfiguration signaling and sent to the terminal. In addition, the configuration cycle of the signaling transmission process is generally hundreds of milliseconds.

Of course, it should be noted that, in addition to the above five methods, the signaling transmission process for transmitting the waveform type indication parameter can also use other signaling transmission processes to transmit the waveform type indication parameter. This is not limited.

Embodiment 1 of the present invention provides an adaptive waveform transmission method. In this method, the base station can determine the current transmission scene information of the terminal, wherein the transmission scene information refers to information indicating the network performance status, and according to the determined information about the current transmission scenario of the terminal, configure the terminal frame structure configuration information corresponding to the current transmission scenario information of the terminal and represent the waveform transmission mode, and send a frame carrying the terminal to the terminal The waveform type indication parameter of the structure configuration information. That is to say, in the technical solution described in the embodiment of the present invention, the base station can adaptively configure a waveform transmission scheme that is suitable for the current transmission scenario information of the terminal according to the current transmission scenario information of the terminal, so as to meet the future fifth It meets the diversified scene requirements of the modern mobile communication technology, thereby improving the user experience.

Embodiment two

Embodiment 2 of the present invention takes the action executing party as a terminal as an example to further describe the adaptive waveform transmission method described in Embodiment 1 of the present invention. This method is applicable to a filter bank multi-carrier system, as shown in FIG. 2 , where It is a schematic flowchart of the adaptive waveform transmission method described in Embodiment 2 of the present invention, and the method may include the following steps:

Step 201: The terminal receives the waveform type indication parameter sent by the base station, the waveform type indication parameter carries the terminal frame structure configuration information corresponding to the current transmission scene information of the terminal and indicating the waveform transmission mode, wherein the The above transmission scenario information refers to information representing a network performance status.

It should be noted that the network performance status can be expressed as high latency, slow movement, small capacity, low latency, high speed mobility or large capacity, etc. Therefore, different network performance status can be represented by different transmission scene information, This embodiment of the present invention does not describe it in detail.

Step 202: Perform signaling transmission according to the waveform transmission mode corresponding to the terminal frame structure configuration information in the waveform type indication parameter.

That is to say, in the technical solution described in the embodiment of the present invention, the terminal can indicate the terminal frame corresponding to the current transmission scene information of the terminal and indicating the waveform transmission mode carried in the parameter according to the waveform type sent by the base station. The waveform transmission mode represented by the structure configuration information is used for signaling transmission, so as to realize the adaptive configuration according to the current transmission scene information of the terminal and the waveform transmission scheme suitable for the current transmission scene information of the terminal, so as to meet the needs of the future fifth generation The diverse scene requirements of mobile communication technology improve user experience.

It should be noted that the transmission scenario may include the channel environment where the terminal is located, the service type of the terminal, the communication type of the terminal, QoS, QoE, or terminal functions, etc., which are not limited in this embodiment of the present invention.

Optionally, the transmission scenario information may be provided by the base station or the terminal itself according to the channel environment where the terminal is located, the service type of the terminal, the communication type of the terminal, the processing capability of the terminal, QoS (Quality of Service, quality of service), QoE (Quality of Experience , quality of experience) or terminal functions and other information, which is not limited in this embodiment of the present invention.

In addition, it should be noted that the terminal frame structure configuration information may at least include: the number of subcarriers, the number of symbols, the number of sampling points for each symbol, the number of subsymbols, and the number of sampling points for each subsymbol, etc., that is, through The waveform transmission mode represented by the terminal frame structure configuration information can be known, and then the terminal can transmit related signaling according to the corresponding waveform transmission mode.

Furthermore, the terminal can also apply to the base station to modify the current default configuration of the waveform transmission mode according to the current transmission scene information of the terminal, which can be specifically implemented as follows:

sending to the base station RRC reconfiguration signaling carrying a waveform transmission mode identifier corresponding to the current transmission scene information of the base station, so that the base station can use the waveform transmission mode identifier carried in the RRC reconfiguration signaling, Configuring terminal frame structure configuration information corresponding to the waveform transmission mode identifier and representing a waveform transmission mode, and sending a waveform type indication parameter carrying the terminal frame structure configuration information to the terminal.

For example, assume that the current default waveform transmission mode of the terminal is OFDM waveform transmission mode, but the terminal needs to modify the current default configuration of OFDM waveform transmission mode to GFDM waveform according to the current transmission scenario information, such as the current channel quality of the terminal. The transmission mode is to meet the resources required by the channel quality of the terminal. At this time, the terminal can send the RRC reconfiguration signaling carrying the GFDM waveform transmission mode identification to the base station, and the base station will transmit the RRC reconfiguration signaling according to the information carried in the received RRC reconfiguration signaling. GFDM waveform transmission mode identification, configuring terminal frame structure configuration information corresponding to the GFDM waveform transmission mode identification and indicating the GFDM waveform transmission mode, and sending the waveform type indication parameter carrying the terminal frame structure configuration information to the terminal , and then the terminal can perform signaling transmission according to the GFDM waveform transmission mode represented by the terminal frame structure configuration information in the received waveform type indication parameter.

It should be noted that when the terminal performs signaling transmission according to the currently configured waveform transmission method, it will perform downlink channel estimation by detecting reference signals such as pilots in the frame structure, but since there are no different resources in the same cell in the LTE system Interference between units (REs). Therefore, for example, when using GFDM waveform transmission mode, without considering the multipath channel and noise, the signal obtained by channel estimation at the receiving end (such as the terminal) can be expressed as the following form,

Wherein: represents the kth subcarrier, the original signal on the _mth subsymbol; Represents the _mth subsymbol, the filter coefficient on the _nth sampling point; Indicates the estimate for _{sk, m} ; M indicates how many subsymbols there are; K indicates how many subcarriers there are; N indicates the number of sampling points for each subsymbol; "*" indicates a conjugate operator; ISI (Inter Symbol Interference); ICI (Inter Carrier Interference).

However, in the multi-carrier system based on the filter bank, there may be inter-block, inter-symbol or inter-sub-symbol interference depending on the specific implementation of the waveform transmission method. Therefore, if the reference signal in the LTE system is used to filter-based In the multi-carrier system of the multi-carrier system, the channel estimation on some resources in the waveform transmission mode configured by the receiving end (such as the terminal) will make the accuracy of the channel estimation low and affect the information of the receiving end (such as the terminal) Transmission quality, therefore, in order to improve the accuracy of channel estimation, some resources in the waveform transmission mode configured by the receiving end (such as terminal) in the filter bank-based multi-carrier system using the reference signal in the LTE system After estimating the channel of , it is necessary to further compensate the result signal obtained by channel estimation. Specifically, it can be implemented as:

According to the waveform transmission mode represented by the terminal frame structure configuration information in the waveform type indication parameter, select the waveform transmission mode represented by the terminal frame structure configuration information from the pre-stored N sets of prototype filter coefficients A matched set of prototype filter coefficients compensates a result signal obtained by performing channel estimation itself, where N is a positive integer.

It should be noted that, in addition to implementing CQI (Channel Quality Indication, Channel Quality Indication) compensation using a filter compensation method, other compensation methods may also be used to implement CQI compensation, which will not be described in detail in this embodiment of the present invention.
