detailed description

The terms used in the implementation part of the present application are only used to explain specific examples of the present application, and are not intended to limit the present application.

The embodiments of the present application can be applied to various types of communication systems. FIG. 1 is a schematic diagram of an application scenario provided by an embodiment of the present application. The communication system shown in FIG. 1 mainly includes a network device 11 and a terminal 12.

Among them, 1) The network device 11 may be a network-side device, for example, an access point (Access Point, AP) of a wireless local area network (Wireless Local Area Network, WLAN), an evolved base station (Evolved Node B, eNB, or eNodeB) of 4G , The next-generation communication base station, such as 5G's new radio access technology (New Radio Access Technology, NR) base station (next generation Node B, gNB) or small station, micro station, can also be a relay station, access point, transmission and Reception point (Transmission and Reception Point, TRP), roadside unit (Road Side Unit, RSU), etc. In this embodiment, base stations in communication systems of different communication standards are different. For the sake of distinction, the base station of the 4G communication system is called LTE eNB, the base station of the 5G communication system is called NR gNB, and the base station that supports both the 4G communication system and the 5G communication system is called Evolutionary Long Term Evolution (evolution, long term evolution, eLTE) ) eNB, these names are for convenience only and do not have a limiting meaning.

2) Terminal 12 is also called user equipment (User Equipment, UE), and is a device that provides voice and / or data connectivity to users, for example, handheld devices with wireless connection functions, vehicle-mounted devices, and V2V communication Capable vehicles, etc. Common terminals include, for example, mobile phones, tablet computers, notebook computers, PDAs, mobile Internet devices (MID), and wearable devices, such as smart watches, smart bracelets, and pedometers.

3) "Multiple" means two or more, and other quantifiers are similar. "And / or" describes the corresponding relationship of the related objects, indicating that there can be three relationships, for example, A and / or B, which can indicate: there are three conditions: A exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the related object is a "or" relationship.

It should be noted that the number and types of terminals 12 included in the communication system shown in FIG. 1 are only an example, and the embodiments of the present application are not limited thereto. For example, more terminals 12 that communicate with the network device 11 may also be included, which are not described one by one in the drawings for concise description. In addition, in the communication system shown in FIG. 1, although the network device 11 and the terminal 12 are shown, the communication system may not be limited to include the network device 11 and the terminal 12, for example, may also include a core network node or Devices and the like that carry virtualized network functions are obvious to those skilled in the art and will not be repeated here.

In addition, the embodiments of the present application can be applied not only to 4G wireless communication systems represented by Long Term Evolution (LTE), vehicle-to-everything (V2X) communication systems, and device-to-device , D2D) communication system, the subsequent evolution of LTE, etc., can also be applied to the next generation wireless communication system, that is, 5G communication system, and other systems that may appear in the future, such as the next-generation wifi network, 5G Internet of Vehicles, etc.

In the embodiment of the present application, taking 5G Internet of Vehicles as an example, as shown in FIG. 2, V2V communication can be directly performed between vehicles, and vehicles and vehicles can perform V2V communication within the coverage of network devices (eg, base stations). V2V communication can be performed outside the coverage of the base station. When the vehicle and the vehicle are performing V2V communication within the coverage of the base station, the base station can be used as a network device to schedule the time-frequency resources of the vehicle and the vehicle's V2V communication. The V2V sender uses the base station's scheduling information to schedule Send V2V communication control messages and data to the V2V receiver. As shown in FIG. 3, the vehicle 31, the vehicle 32, and the vehicle 33 perform V2V communication within the coverage of the base station, and the vehicle 34 and the vehicle 35 perform V2V communication outside the coverage of the base station. For example, the base station may schedule time-frequency resources for V2V communication between the vehicle 31 and the vehicle 32, and the vehicle 31 sends control messages and data of V2V communication to the vehicle 32 on the scheduled time-frequency resources according to the scheduling information of the base station.

The current V2V communication based on the Long Term Evolution (LTE) system includes two communication modes: the first communication mode is based on the V2V communication scheduled by the base station, and the V2V sender uses the scheduled information of the base station on the scheduled time-frequency resources Send V2V communication control messages and data to the V2V receiving end; the second communication mode is that the V2V sending end selects the time-frequency resources used for communication among the available time-frequency resources included in the resource set for V2V communication, and selects Send control messages and data on your resources. Among them, the resource set used for V2V communication can be regarded as a set of time resources and frequency resources used for V2V communication. The base station needs to send instruction information to the terminal to instruct the terminal: a set of time resources for V2V communication and a set of frequency domain resources for V2V communication in all time-frequency resources in the communication system.

Taking the base station instructing the terminal to indicate the time resource set used for V2V communication among all time resources in the communication system, for example, in the LTE communication system, the time resource specifically refers to a time slot, and the base station sends a bit map (bit map) to the terminal. The map is used to indicate the set of time slots used for V2V communication among all time slots in the communication system. The bit map may specifically be a bit sequence. This embodiment does not limit the length of the bit sequence. Each of the bit sequences The bit is used to identify whether a time slot in the communication system can be used for V2V communication. Optional, if the bit is 1, it means the time slot corresponding to the bit can be used for V2V communication, if the bit is 0, it means the The time slot corresponding to the bit cannot be used for V2V communication. For example, the bit sequence includes 8 bits, and the 8 bits are 10010001. The 8 bits correspond to 8 time slots. For example, the first bit 1 corresponds to time slot 0, and the second bit 0 corresponds to time slot 1. By analogy, the 8th bit 1 corresponds to time slot 7, indicating that time slot 0, time slot 3, time slot 7 can be used for V2V communication, time slot 1, time slot 2, time slot 4, time slot 5, time slot 6 cannot Used for V2V communication. Since there are many time slots in the communication system, after receiving the 8-bit bit map, the terminal can not only determine the time slots for V2V communication among the 8 time slots 0-7, but also The bit map is periodically repeated. The so-called periodic repetition can be specifically shown in FIG. 4. Assuming that time slots 0-N represent all time slots in the communication system, the terminal is using the bit map 10010001 and time slots 0-7. After one-to-one correspondence, the bit map 10010001 can also be mapped to the eight time slots after time slots 0-7, ie time slots 8-15, to determine the time slots used for V2V communication in time slots 8-15 , Further, one-to-one correspondence between the bit map 10010001 and the 8 time slots after time slots 8-15, ie, time slots 16-23, and so on, until the bit map 10010001 and the last 8 time slots in the communication system One-to-one correspondence, so as to determine the set of time slots for V2V communication among all time slots in the communication system.

For frequency resources in the resource set used for V2V communication, the base station divides the frequency band used for V2V communication into several sub-channels, each sub-channel includes a certain number of resource blocks (Resource, Block, RB), and one RB is occupied in the time domain A time slot occupies 12 subcarriers in the frequency domain, and the length of a subchannel and a resource block in the time domain may be the same. Among them, the resource set used for V2V communication can be regarded as a set of time resources and frequency resources used for V2V communication, and the resource set used for V2V communication is a part of all time-frequency resources in the communication system, that is, communication Some of the time-frequency resources in the system can be used for V2V communication.

As shown in FIG. 5, sub-channel 1, sub-channel 2, ... sub-channel N is a schematic diagram of frequency resources in the resource set for V2V communication, and the base station may use the first frequency resource in the resource set for V2V communication. The sequence number of a resource block, such as the sequence number of the first resource block in subchannel 1, the total number of subchannels N included in the resource set for V2V communication, the number of resource blocks included in each subchannel n _{CH is} sent to The terminal can determine the frequency resources available for V2V communication among all the spectrum resources in the communication system according to the foregoing information sent by the base station. Optionally, V2V communication occupies one or more sub-channels in the frequency domain and occupies a time slot in the time domain. In this embodiment, the time slot used for V2V communication is referred to as a V2V time slot or a V2X time slot.

In the LTE system, a V2X time slot includes 14 orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) symbols, as shown in Figure 6, the first OFDM symbol is generally used as a terminal for automatic gain control (Automatic Gain) Control, AGC), the last symbol is used as a guard interval (gap), which is mainly used for terminal to send and receive conversion and time advance (TA) adjustment. In addition, in the LTE system, the subcarrier spacing is fixed at 15Khz, the duration of the first OFDM symbol is 71.9 microseconds, and the duration of the last OFDM symbol is 66.7 microseconds.

However, in the next generation wireless communication system, that is, 5G communication system, the subcarrier spacing is not fixed, for example, it can be 15kHz, 30kHz, 60kHz, 120kHz, 240kHz, and the greater the subcarrier spacing, the shorter the OFDM symbol in the time domain . When the terminal works in the frequency range 1 that is less than 6 GHz, the time for sending and receiving conversion is 13 microseconds, and the time required for the AGC is 15 microseconds; when the terminal works in the frequency range 2 that is greater than 6 GHz, the time for sending and receiving conversion is 7 microseconds. The time required for AGC is 10 microseconds; therefore, in a 5G communication system, when the subcarrier interval becomes larger, one OFDM symbol becomes shorter in the time domain. If the OFDM symbol corresponding to the AGC or guard interval is still fixed to 1 OFDM Symbol, it may not meet the needs of the terminal. In order to solve this problem, the present application provides a method for configuring communication resources, which can flexibly configure the number of OFDM symbols corresponding to a guard interval in a time slot in a 5G communication system, and / or OFDM corresponding to AGC The number of symbols. The method is described below in conjunction with specific embodiments.

7 is a schematic diagram of a method for configuring communication resources provided by the present application. As shown in FIG. 7, the communication resource configuration method described in this embodiment includes the following steps:

Step S701: The network device sends control signaling to the first terminal, where the control signaling includes configuration information.

In this embodiment, the network device may specifically be a base station, and the first terminal, the second terminal, and the third terminal may perform sidelink communication (sidelink), and the sidelink communication may specifically be vehicle-to-outside information exchange (vehicle) to everything (V2X) communication, in which V2V communication is performed between any two of the first terminal, the second terminal, and the third terminal, and the side link may specifically be a V2X communication link or a V2V communication link. In the 5G communication system, the time resource specifically refers to a time slot, which is equivalent to the time slot in the LTE system. In this embodiment, the time slot for side communication is recorded as the time slot for the side link, for example, it will be used for V2X The time slot for communication is denoted as V2X time slot. Optionally, the time slot of a side link includes 14 OFDM symbols, and the time slot of a side link here may refer to a side link The time slot is not limited to a specific time slot of a specific side link. For example, a time slot of a side link may specifically be a time slot of a side link when side communication is performed between any two terminals, or any one of the resource sets used for V2V communication may be used for the side line Time slot for communication.

In this embodiment, the number of OFDM symbols corresponding to the guard interval in the time slot of one side link can have multiple configuration methods, and / or, the OFDM corresponding to the automatic gain control AGC in the time slot of one side link The number of symbols can be configured in multiple ways.

Taking the number of OFDM symbols corresponding to the guard interval as an example, as shown in FIG. 8, the number of OFDM symbols corresponding to the guard interval in the time slot of a side link can have the following optional configurations:

One configuration method is: the number of OFDM symbols corresponding to the guard interval in the time slot of a side link is 0, that is, the guard interval is not included in the time slot. Since the guard interval does not carry information, when the number of OFDM symbols corresponding to the guard interval in a time slot of a side link is 0, a time slot of a side link can transmit more information, thereby increasing the time Frequency resource utilization.

Another configuration method is: the number of OFDM symbols corresponding to the guard interval in the time slot of a side link is 1, that is, the guard interval occupies one OFDM symbol in the time slot, for example, the last OFDM in the time slot The symbol serves as a guard interval. In this case, it means that configuring an OFDM symbol for the guard interval does not affect normal communication. That is, without affecting normal communication, it is sufficient to configure an OFDM symbol for the guard interval. Multiple OFDM symbols may result in low resource utilization.

Another configuration method is: the number of OFDM symbols corresponding to the guard interval in a time slot of a side link is 2, that is, the guard interval occupies two OFDM symbols in the time slot, for example, the 13th of the time slot OFDM symbols and the 14th OFDM symbol are used as guard intervals. In this case, it means that configuring the guard interval with two OFDM symbols does not affect normal communication, that is, without affecting normal communication, it is sufficient to configure the guard interval with two OFDM symbols. Configuring more OFDM symbols may result in low resource utilization.

Another configuration method is: the number of OFDM symbols corresponding to the guard interval in a time slot of a side link is 3, that is, the guard interval occupies 3 OFDM symbols in the time slot, for example, the 12th of the time slot OFDM symbols, the 13th OFDM symbol and the 14th OFDM symbol are used as guard intervals. In this case, it means that allocating 3 OFDM symbols to the guard interval does not affect normal communication, that is, without affecting normal communication, it is sufficient to configure 3 OFDM symbols to the guard interval. Configuring more OFDM symbols may result in low resource utilization.

In this embodiment, the base station may configure the number of OFDM symbols corresponding to the guard interval in the time slot of a side link according to the actual situation of the network or the terminal. For example, the first terminal is a V2X transmitting terminal, and the third terminal is a V2X receiving terminal. Specifically, the first terminal may be an on-board device in a vehicle 31 as shown in FIG. 3, and the third terminal may be as shown in FIG. The on-board equipment in the vehicle 32, the first terminal and the third terminal are within the coverage of the base station. The side link between the first terminal and the third terminal is a V2X unicast link. If the V2X receiver does not have V2X data or uplink data needs to be sent in the next time slot of the current time slot, the base station can configure the current time The number of OFDM symbols corresponding to the guard interval in the slot is 0. If the V2X receiving end performs V2X transmission in the next time slot, and the guard interval is mainly used for the V2X receiving end to perform transceiver conversion, the base station can configure the number of OFDM symbols corresponding to the guard interval in the current time slot to be 1. If the V2X receiving end performs uplink transmission in the next time slot, and the guard interval is used for V2X receiving end to perform transceiver conversion and TA, the base station can configure the number of OFDM symbols corresponding to the guard interval in the current time slot to be 2 or 3. It can be understood that this is only a schematic description, and does not limit the specific number of OFDM symbols corresponding to the guard interval in a time slot of a side link. In other embodiments, a time slot of a side link may also be used. More OFDM symbols are used as guard intervals.

As shown in FIG. 9, the number of OFDM symbols corresponding to AGC in the time slot of a side link can have the following optional configurations:

One configuration method is: the number of OFDM symbols corresponding to AGC in a time slot of a side link is 0, that is, AGC is not included in the time slot. In this case, the time slot of a side link can transmit more information, thereby improving the utilization rate of time-frequency resources.

Another configuration method is: the number of OFDM symbols corresponding to AGC in a time slot of a side link is 1, that is, AGC occupies one OFDM symbol in the time slot, for example, the first OFDM symbol of the time slot Used for AGC. In this case, it means that allocating an OFDM symbol to AGC does not affect normal communication. That is, without affecting normal communication, it is sufficient to configure an OFDM symbol to AGC. If more OFDM is configured to AGC Symbol may cause low resource utilization.

Another configuration method is: the number of OFDM symbols corresponding to AGC in a time slot of a side link is 2, that is, in this time slot, AGC occupies two OFDM symbols, for example, the first OFDM of the time slot The symbol and the second OFDM symbol are used for AGC. In this case, it means that configuring AGC with two OFDM symbols does not affect normal communication. That is, without affecting normal communication, it is sufficient to configure AGC with two OFDM symbols. If AGC is configured with more OFDM symbols may result in low resource utilization.

Another configuration mode is: the number of OFDM symbols corresponding to AGC in a time slot of a side link is 3, that is, in this time slot, AGC occupies 3 OFDM symbols, for example, the first OFDM of the time slot The symbol, the second OFDM symbol, and the third OFDM symbol are used for AGC. In this case, it means that configuring AGC with 3 OFDM symbols does not affect normal communication. That is to say, without affecting normal communication, it is enough to configure AGC with 3 OFDM symbols. If AGC is configured with more OFDM symbols may result in low resource utilization.

It can be understood that this is only a schematic description, and does not limit the specific number of OFDM symbols corresponding to AGC in a time slot of a side link. In other embodiments, a time slot of a side link may also be used. More OFDM symbols are used for AGC.

In addition, the base station can also reasonably configure the number of OFDM symbols corresponding to AGC in the time slot of a side link according to the actual situation of the network or terminal. The specific process and the base station are based on the data transmission status of the V2X receiver in the V2X unicast link The number of OFDM symbols corresponding to the guard interval in the time slot configuring a side link is similar, and will not be repeated here.

In this embodiment, the base station may indicate the number of OFDM symbols corresponding to the guard interval in the time slot of one side link by sending control signaling to the first terminal, and / or the time of one side link The number of OFDM symbols corresponding to AGC in the slot.

Specifically, the base station sends control signaling to the first terminal, where the control signaling includes configuration information, and the configuration information includes a first identifier and / or a second identifier, and the first identifier is used to indicate the time of a side link The number of OFDM symbols corresponding to the guard interval in the slot. The first identification may be one or more bits in the configuration information. For example, the first identifier may be two bits in the configuration information. If the two bits are 00, it means that the number of OFDM symbols corresponding to the guard interval in the time slot of a side link is 0; If the two bits are 01, it means that the number of OFDM symbols corresponding to the guard interval in the time slot of a side link is 1; if the two bits are 10, it means the time of a side link The number of OFDM symbols corresponding to the guard interval in the slot is two; if the two bits are 11, it means that the number of OFDM symbols corresponding to the guard interval in the time slot of a side link is three. This is only a schematic illustration. If the number of OFDM symbols corresponding to the guard interval in the time slot of a side link is greater than 3, you can also use more bits in the configuration information to identify the time of a side link The number of OFDM symbols corresponding to the guard interval in the slot.

Similarly, the second identifier is used to indicate the number of OFDM symbols corresponding to AGC in the time slot of a side link, and the second identifier may also be one or more bits in the configuration information. For example, the second identifier may be two bits in the configuration information. It can be understood that the two bits here and the two bits corresponding to the first identifier are bits at different positions in the configuration information. The two bits corresponding to the second identification indicate the number of OFDM symbols corresponding to the AGC in the time slot of a side link and the two bits corresponding to the first identification indicate the protection in the time slot of a side link The method of the number of OFDM symbols corresponding to the interval is consistent, and the specific process will not be repeated here.

In another possible implementation, the configuration information included in the control signaling may include an identifier, which is used to simultaneously indicate the number of OFDM symbols corresponding to the guard interval in the time slot of a side link and the corresponding AGC The number of OFDM symbols. The identification may be one or more bits in the configuration information. For example, the identifier is two bits in the configuration information. If the two bits are 00, it indicates the number of OFDM symbols corresponding to the guard interval in the time slot of a side link and the OFDM symbols corresponding to AGC The number of both is 0; if the two bits are 01, it means that the number of OFDM symbols corresponding to the guard interval and the number of OFDM symbols corresponding to AGC in the slot of a side link are both 1; If the two bits are 10, it means that the number of OFDM symbols corresponding to the guard interval and the number of OFDM symbols corresponding to AGC in the time slot of a side link are 2; if the two bits are 11 , It means that the number of OFDM symbols corresponding to the guard interval and the number of OFDM symbols corresponding to AGC in a time slot of a side link are both 3. This is only a schematic illustration. If the number of OFDM symbols corresponding to the guard interval and the number of OFDM symbols corresponding to AGC in a time slot of a side link are both greater than 3, more of the configuration information can also be used. Bits identify the number of OFDM symbols corresponding to the guard interval and the number of OFDM symbols corresponding to AGC in the time slot of a side link.

In addition, the control signaling sent by the base station to the first terminal may have the following possible situations:

One possible situation is that the control signaling is Downlink Control Information (DCI). That is, the downlink control information DCI includes the configuration information, and the base station may indicate the number of OFDM symbols corresponding to the guard interval in the time slot of a side link currently scheduled by the base station by sending DCI to the first terminal, and / Or, the number of OFDM symbols corresponding to AGC in a time slot of a side link currently scheduled by the base station. Optionally, the first terminal and the third terminal perform V2X communication, the first terminal is a V2X transmitter, and the third terminal is a V2X receiver, and the base station can schedule the time-frequency resources for the V2X communication between the first terminal and the third terminal , And through DCI to dynamically indicate the number of OFDM symbols corresponding to the guard interval in the currently scheduled V2X time slot, and / or the number of OFDM symbols corresponding to the AGC in the currently scheduled V2X time slot. For example, at the current moment, the base station indicates the number of OFDM symbols corresponding to the guard interval in the currently scheduled V2X time slot by DCI, and the next time the base station indicates the guard interval in the scheduled V2X time slot at the next time by DCI. The number of OFDM symbols is 2.

Another possible situation is that the control signaling is high-level signaling, and the high-level signaling is radio resource control (Radio Resource Control, RRC) signaling. The base station may indicate the number of OFDM symbols corresponding to the guard interval in each time slot in the resource set for V2V communication by sending RRC signaling to the first terminal, and / or the resource set for V2V communication The number of OFDM symbols corresponding to AGC in each time slot in. For example, the RRC signaling includes configuration information including the first identifier and / or the second identifier as described above, if the first identifier indicates the OFDM symbol corresponding to the guard interval in the time slot of a side link If the number is m, it means that the number of OFDM symbols corresponding to the guard interval in each V2X slot in the resource set for V2V communication is m. Similarly, if the second identifier indicates that the number of OFDM symbols corresponding to AGC in a time slot of a side link is n, it means that the OFDM symbols corresponding to AGC in each V2X time slot in the resource set used for V2V communication The number of is n.

In addition, the base station may indicate that the number of OFDM symbols corresponding to the guard interval in each time slot in the resource set for V2V communication has been updated by sending RRC signaling to the first terminal again, and / or The number of OFDM symbols corresponding to AGC in each time slot in the resource set of V2V communication is updated.

For example, the base station sends RRC signaling to the first terminal again. The RRC signaling includes configuration information including the first identifier and / or the second identifier as described above, if the first identifier indicates a side link The number of OFDM symbols corresponding to the guard interval in the timeslot is j, indicating that the number of OFDM symbols corresponding to the guard interval in each V2X time slot in the resource set used for V2V communication is updated to j. Similarly, if the second identifier indicates that the number of OFDM symbols corresponding to AGC in a time slot of a side link is h, it means that the OFDM symbols corresponding to AGC in each V2X time slot in the resource set used for V2V communication The number of is updated to h.

And data. Optionally, the side control information may further include the configuration information to indicate the number of OFDM symbols corresponding to the guard interval in the time slot of a side link of the V2X receiving end, and / or, the The number of OFDM symbols corresponding to AGC in the time slot.

If the control signaling received by the V2X sending end from the base station is DCI, the V2X sending end may include the configuration information in the side control information sent to the V2X receiving end to indicate the V2X receiving end: the currently scheduled V2X time slot The number of OFDM symbols corresponding to the guard interval in the middle, and / or the number of OFDM symbols corresponding to AGC in the currently scheduled V2X time slot. The base station can dynamically indicate the number of OFDM symbols corresponding to the guard interval in the currently scheduled V2X time slot by sending DCI to the V2X sending end, and / or the OFDM symbol corresponding to the AGC in the currently scheduled V2X time slot Number. If the control signaling received by the V2X sending end from the base station is high-level signaling such as RRC signaling, the V2X sending end may include the configuration information in the side control information sent to the V2X receiving end to indicate to the V2X receiving end: The number of OFDM symbols corresponding to the guard interval in each V2X slot in the resource set for V2V communication, and / or the number of OFDM symbols corresponding to AGC in each V2X slot in the resource set for V2V communication. The base station may indicate the number of OFDM symbols corresponding to the guard interval in each time slot in the resource set used for V2V communication by sending high-level signaling such as RRC signaling to the V2X sending end, and / or The number of OFDM symbols corresponding to AGC in each time slot in the resource set of V2V communication.

In addition, when the V2X transmitter and / or V2X receiver are not within the coverage of the base station, the system will pre-configure the resource set for V2V communication, for example, for each V2X time slot in the resource set for V2V communication Pre-configure the number of OFDM symbols corresponding to the guard interval in the middle, and / or pre-configure the number of OFDM symbols corresponding to the AGC in each V2X slot in the resource set used for V2V communication.

In addition, the method described in this embodiment is also applicable to a mini-slot. Compared with a time slot, the mini-slot may include a smaller number of OFDM symbols. For example, the mini-slot includes 8 OFDM symbols.

In this embodiment, control signaling is sent to the terminal through the network device, and the control signaling includes configuration information used to indicate the number of OFDM symbols corresponding to the guard interval in the time slot of a side link, and / or The configuration information is used to indicate the number of OFDM symbols corresponding to the AGC in the time slot of a side link, to achieve flexible configuration of the number of OFDM symbols corresponding to the guard interval in the time slot of a side link, and / or, The flexible configuration of the number of OFDM symbols corresponding to AGC in the time slot of a side link makes the OFDM symbol corresponding to the AGC or guard interval not fixed to 1 OFDM symbol, thereby meeting the needs of terminals in different communication systems.
