Description

Straight-through link configuration method, device, terminal and network equipment

Technical Field

The present application relates to the field of communications technologies, and in particular, to a method, an apparatus, a terminal, and a network device for configuring a through link.

Background

In a 5G NR (new radio access technology) V2X (internet of things) system, direct communication is performed between terminals on a direct link (sidlink). Before the service data transmission, the time-frequency resource used by the through link data transmission needs to be determined first, and the main criterion for determining the time-frequency resource is to avoid collision between the time-frequency resources used by different terminals so as to avoid mutual interference. In NR V2X, there are two resource scheduling modes, the first is a Mode (Mode) 1 resource allocation Mode, in which the base station uniformly schedules time-frequency resources used by each terminal in the through link communication, and the second is a Mode2 resource allocation Mode, in which the terminal autonomously selects the time-frequency resources used in the through link communication without participation of the base station.

The 5G NR-V2X Mode2 adopts distributed resource scheduling, and because the base station does not have unified scheduling, the UE (terminal) needs to determine the resource occupation condition of other UEs through a resource sensing mechanism, and performs resource selection according to a resource sensing result. Compared with a completely random resource selection mechanism, the resource utilization rate can be improved through a resource sensing mechanism, the collision probability is reduced, and the system performance is improved.

Specifically, in the prior art, in the distributed resource scheduling mode, the terminal performs resource elimination according to the result of its own resource awareness, that is, eliminates the conflict resource perceived by itself. However, in the current network deployment, the 4G terminal and the 5G terminal exist simultaneously, so when the 4G terminal and the 4G terminal perform direct link communication, and meanwhile, the 5G terminal and the 5G terminal also perform direct link communication, the two direct link communication are in different communication systems, so that the opposite party cannot be perceived, and the problem that the resources occupied by the 4G direct link and the 5G direct link collide to cause mutual interference occurs.

Therefore, the problem that the scheduling resources of different communication systems cannot be supported to avoid collision in the prior art can not be solved.

In the resource sensing process, different characteristics of periodic service and aperiodic service in a mixed service scene in NR V2X application and influence of service types on a resource sensing result need to be considered. Meanwhile, proper resource sensing configuration is required to be carried out according to the time-frequency resource granularity, the resource pool setting and other information in the physical channel. The resource sensing window refers to a time window for sensing resources by the terminal.

(2) And (3) resource elimination: the main purpose of the resource elimination is to eliminate resources which are not used for resource selection in a resource selection window according to a perceived result, such as eliminating time-frequency resources which are occupied by a terminal for receiving data (NR V2X terminal carries out data receiving and transmitting in a half duplex mode, and half duplex means that the terminal cannot receive and transmit data at the same time), so as to form a candidate resource set, reduce the probability of resource collision and improve the reliability.

(3) And (3) resource selection: the resource selection mechanism is to select a suitable transmission time-frequency resource for a service packet TB (transport block) to be transmitted in a candidate resource set, and needs to consider the priority, time delay, service packet size and transmission reliability requirements of the service to perform resource selection. The resource selection window refers to a time window in which the terminal performs resource selection.

The 5G NR-V2X Mode 2 adopts a distributed resource scheduling mechanism, and because the base station does not have unified scheduling, the UE needs to determine the resource occupation condition of other UEs through a resource sensing mechanism, and performs resource selection according to a resource sensing result. Compared with a completely random resource selection mechanism, the resource utilization rate can be improved through a resource sensing mechanism, the collision probability is reduced, and the system performance is improved. And 4g LTE Mode4 also employs the distributed resource scheduling mechanism described above.

When the traffic arrives, the terminal receives the data packet in the resource aware window and decodes SCI (through link control information), the resources falling in the resource selection window and having RSRP greater than the RSRP threshold value need to be excluded, the remaining resources are candidate resources, and then the resources required for through link transmission are randomly selected from the candidate resources with the minimum 20% of RSSI (received signal strength indication) or directly selected from all the candidate resources. Wherein the length of the resource selection window may be configured as the maximum period of traffic.

Before data transmission on the direct link, the terminal firstly carries out resource sensing and carries out resource selection according to the result of the resource sensing, and the mechanism can avoid collision to a certain extent. As shown in fig. 2, the terminal may exclude the perceived conflicting resources when performing the resource selection.

And configuring all or part of the occupied period of the first sub-channel set as the SL DRX inactive period of the second terminal, and configuring all or part of the occupied period of the second sub-channel set as the SL DRX active period of the second terminal according to the resource pool configuration information.

3. The indication information is priority related information (which may be used based on resource pool (pre) configuration information or directly alone):

(12) The 4G through link communication of terminal a is configured to use a first resource pool and the 5G through link communication of terminal B is configured to use a second resource pool. When the first resource pool and the second resource pool are overlapped on the time domain or the frequency domain, the terminal with higher priority uses the overlapped part of the resource pools, and the terminal with lower priority does not use the overlapped part of the resource pools according to the priority related information. Corresponding to the situation that the priority information indicates that the priority of the first terminal is higher than the priority of the second terminal, when the first resource pool and the second resource pool are overlapped in the time domain and/or the frequency domain, the first terminal uses the overlapped part of resource pools, and the second terminal does not use the overlapped part of resource pools; or when the priority information indicates that the priority of the first terminal is lower than the priority of the second terminal, the first terminal does not use the overlapped partial resource pool when the first resource pool and the second resource pool are overlapped in the time domain and/or the frequency domain, and the second terminal uses the overlapped partial resource pool. (13) The 4G through link communication of terminal a is configured to use a first set of subchannels of the third resource pool and the 5G through link communication of terminal B is configured to use a second set of subchannels of the third resource pool. When the first sub-channel set and the second sub-channel set overlap in the time domain or the frequency domain, the terminal with higher priority uses the overlapping sub-channels and the terminal with lower priority does not use the overlapping sub-channels according to the priority related information. Corresponding to the situation that the priority information indicates that the priority of the first terminal is higher than the priority of the second terminal, when the first sub-channel set of the third resource pool and the second sub-channel set of the third resource pool overlap in the time domain and/or the frequency domain, the first terminal uses the overlapped sub-channels, and the second terminal does not use the overlapped sub-channels; or when the priority information indicates that the priority of the first terminal is lower than the priority of the second terminal, the first terminal does not use the overlapped sub-channels when the first sub-channel set of the third resource pool and the second sub-channel set of the third resource pool overlap in the time domain and/or the frequency domain, and the second terminal uses the overlapped sub-channels.

(14) The priority information is a system priority (corresponding to the above-described through link priority), that is: 4G through link communication priority, or 5G through link communication priority. The priority information may be represented in 1 bit, such as: 0 indicates 4G through link communication priority, and 1 indicates 5G link communication priority. The first bit is used for representing the priority of the corresponding through link; when the value of the first bit is a first value, the priority of the first communication system direct link is higher than the priority of the second communication system direct link; and under the condition that the value of the first bit is a second value, the priority of the first communication system direct link is lower than that of the second communication system direct link.

(15) The priority information is the terminal priority, namely: the through link communication of terminal a takes precedence, or the through link communication of terminal B takes precedence. The priority information may be represented in N1 bits (N1. Gtoreq.1), for example: when n1=2, 00 indicates that the through link communication priority of terminal a is 0, 11 indicates that the through link communication priority of terminal B is 3, and the smaller the priority value, the higher the priority. The second bit is used for representing the priority of the terminal; when the value of the second bit is a third value, the priority of the first terminal is higher than the priority of the second terminal; and under the condition that the value of the second bit is a fourth value, the priority of the first terminal is lower than that of the second terminal.

(16) The priority information is traffic priority, i.e.: the current traffic through link communication of terminal a takes precedence, or the current traffic through link communication of terminal B takes precedence. The priority information may be represented in N2 bits (N2. Gtoreq.1), for example: when n2=3, 101 indicates that the current traffic through link communication priority of terminal a is 5, 010 indicates that the current traffic through link communication priority of terminal B is 2, and the smaller the priority value, the higher the priority. A third bit is adopted to represent the service priority; when the value of the third bit is a fifth value, the priority of the first service is higher than that of the second service; and under the condition that the value of the third bit is a sixth value, the priority of the first service is lower than that of the second service.

(17) If the priority of terminal a is the same as that of terminal B, then either terminal a or terminal B may change the time-frequency resources that the direct link communication is configured to use in accordance with the system (pre) configuration. Corresponding to the case that the priority information indicates that the priority of the first terminal is equal to the priority of the second terminal, when the time-frequency resource used by the first communication-mode direct link of the first terminal is overlapped with the time-frequency resource used by the second communication-mode direct link of the second terminal, the first terminal replaces the time-frequency resource used by the first communication-mode direct link, or the second terminal replaces the time-frequency resource used by the second communication-mode direct link.

4. The indication information is SL DRX information:

(18) The 4G through link communication of the terminal a is configured to use a first resource pool, the 5G through link communication of the terminal B is configured to use a second resource pool, the first resource pool and the second resource pool are configured according to the SL DRX information of the terminal B (corresponding to the first terminal configuring through link communication related resources according to the first indication information, the second terminal configuring through link communication related resources according to the second indication information):

all or part of the SL DRX inactivity period of the terminal B is configured as the occupied period of the first resource pool, and all or part of the SL DRX inactivity period of the terminal B is configured as the occupied period of the second resource pool. And corresponding to the determination that the whole period or part of the SL DRX inactive period of the second terminal is configured as the occupied period of the first resource pool according to the SL DRX information, and the whole period or part of the SL DRX active period of the second terminal is configured as the occupied period of the second resource pool. The first terminal configures related resources of the direct link communication according to the occupation period of the first resource pool; and the second terminal configures related resources of the direct link communication according to the occupied time period of the second resource pool.

(19) The 4G through link communication of the terminal A is configured to use a first subchannel set of a third resource pool, the 5G through link communication of the terminal B is configured to use a second subchannel set of the third resource pool, the first subchannel set and the second subchannel set are configured according to SL DRX information of the terminal B (corresponding to the first terminal configuring through link communication related resources according to the first indication information; the second terminal configuring through link communication related resources according to the second indication information):

all or part of the SL DRX inactive period of terminal B is configured as the occupied period of the first subchannel set, and all or part of the SL DRX active period of terminal B is configured as the occupied period of the second subchannel set. And corresponding to the determination that the whole period or part of the SL DRX inactive period of the second terminal is configured as the occupied period of the first sub-channel set according to the SL DRX information, and the whole period or part of the SL DRX active period of the second terminal is configured as the occupied period of the second sub-channel set. The first terminal configures related resources of the direct link communication according to the occupied time period of the first sub-channel set; and the second terminal configures related resources of the direct link communication according to the occupied time period of the second sub-channel set.

5. Other:

(20) The first resource pool, the second resource pool, the first sub-channel set, and the time slots or subframes occupied by the second sub-channel set are configured in the form of a bitmap (bitmap). The corresponding target slots or target subframes are configured in a bitmap manner. The configuration of the third resource pool is also applicable, and is not limited herein.

The following specifically illustrates the scheme provided by the embodiment of the present application.

Example 1 (base station, terminal B or terminal C sends indication information);

this example relates to the following:

terminal a and terminal B configure a resource pool or SL DRX according to indication information (pre) including at least one of resource pool (pre) configuration information, priority related information, SL DRX information, and the like. The indication information is sent by the base station, the terminal B or the terminal C, and in this scheme, the indication information may also be preconfigured. Terminal a supports only 4G through links, while terminals B and C support both 4G through links and 5G through links.

Terminal a is a terminal supporting only 4G through links; terminal B and terminal C are terminals supporting both the 4G through link and the 5G through link.

The indication information is sent by the base station, the terminal B or the terminal C, and in this scheme, the indication information may also be preconfigured.

When terminal a or terminal B is within coverage, the base station transmits indication information to terminal a or terminal B.

When the terminal a or the terminal B is out of coverage, the terminal B transmits the indication information to the terminal a using the 4G through link, so that the terminal a obtains the indication information.

When the terminal a or the terminal B is out of coverage, the terminal C transmits the indication information to the terminal a using the 4G through link, and the terminal C transmits the indication information to the terminal B using the 5G through link, so that the terminal a and the terminal B obtain the indication information.

When the terminal a or the terminal B is out of coverage, the terminal a and the terminal B may obtain the indication information based on the preconfigured information.

The coverage may be coverage of a downlink signal transmitted by a base station, and when the terminal a and the terminal B are located in the coverage, a base station signal may be received, so that the 4G base station or the 5G base station may send indication information to the terminal a or the terminal B. Outside the coverage of the base station, the terminal A and the terminal B cannot receive the signals of the base station, so that the terminal B or the terminal C can send the indication information to the terminal A or the terminal B (specifically, the terminal B or the terminal C can be sent to the terminal A or the terminal C can be sent to the terminal B); in this scheme, the terminal a and the terminal B may obtain the indication information based on the preconfigured information, which is not limited herein.

By adopting the method for sending the indication information, the terminal A and the terminal B can obtain the indication information, so that the 4G direct link communication of the terminal A and the 5G direct link communication of the terminal B can coexist, the probability of data packet transmission failure caused by resource collision is reduced, and the direct link data packet transmission success rate is improved.

Example 2 (example 1 where the indication information is resource pool (pre) configuration information);

this example relates to the following:

and the terminal A and the terminal B configure a resource pool according to the indication information. The indication information is resource pool (pre) configuration information. The indication information is transmitted by the base station, terminal B or terminal C, or the indication information is preconfigured. Terminal a supports only 4G through links, while terminals B and C support both 4G through links and 5G through links.

According to the resource pool pre-configuration or the resource pool configuration information, the 4G through link communication of the terminal A is configured to use a first resource pool, the 5G through link communication of the terminal B is configured to use a second resource pool, and the first resource pool and the second resource pool are not overlapped in the time domain or the frequency domain;

according to the resource pool pre-configuration or the resource pool configuration information, the 4G through link communication of the terminal A is configured to use a first subchannel set of a third resource pool, the 5G through link communication of the terminal B is configured to use a second subchannel set of the third resource pool, and the first subchannel set and the second subchannel set are not overlapped in the time domain or the frequency domain;

The resource pool pre-configuration or resource pool configuration information indicates a time-frequency configuration of the first resource pool or the second resource pool within one SFN or DFN period.

The resource pool pre-configuration or resource pool configuration information is sent to the terminal a or the terminal B by the base station in the coverage, and the terminal a or the terminal B is sent by other terminals (such as the terminal C) outside the coverage.

As shown in fig. 6, each of the tiles in the figure represents one sub-channel, which is composed of a plurality of consecutive PRBs (physical resource blocks), and a plurality of consecutive sub-channels form one resource pool, and one SFN is assumed to be 10ms. According to the resource pool pre-configuration or the resource pool configuration information, (determining:) the 4G through link communication of the terminal A is configured to use a first resource pool (the resource pool which is not filled by a solid line frame in the corresponding diagram), the 5G through link communication of the terminal B is configured to use a second resource pool (the resource pool which is filled by oblique lines in the corresponding diagram), and the first resource pool and the second resource pool are not overlapped in the frequency domain, namely: the two sub-channels occupy different sub-channels. The configuration information indicates a time-frequency configuration of the first resource pool or the second resource pool within one SFN or DFN period.

As shown in fig. 7, each of the tiles represents a sub-channel, which is composed of a plurality of consecutive PRBs, and a plurality of consecutive sub-channels form a resource pool, and an SFN is assumed to be 10ms. Terminal a and terminal B configure (determine:) the 4G through link communication of terminal a is configured to use a first set of subchannels of a third resource pool (corresponding to the unfilled subchannel set in the solid line box in the figure) and the 5G through link communication of terminal B is configured to use a second set of subchannels of the third resource pool (corresponding to the diagonally filled subchannel set in the solid line box in the figure), the first and second sets of subchannels do not overlap in time domain, i.e.: the two sub-channels occupy different sub-frames. The configuration information indicates a time-frequency configuration of the first resource pool or the second resource pool within one SFN or DFN period.

By adopting the indication method of the (pre) configuration information of the resource pool, the terminal A and the terminal B can configure the resource pool according to the (pre) configuration information of the resource pool, so that the 4G direct link communication of the terminal A and the 5G direct link communication of the terminal B can coexist, the probability of data packet transmission failure caused by resource collision is reduced, the direct link data packet transmission success rate is improved, and the signaling is simple.

Example 3 (indicating information is priority related information);

this example relates to the following:

and the terminal A and the terminal B configure a resource pool according to the indication information. The indication information is priority related information. The indication information is transmitted by the base station, terminal B or terminal C, or the indication information is preconfigured. Terminal a supports only 4G through links, while terminals B and C support both 4G through links and 5G through links.

The 4G through link communication of terminal a is configured to use a first resource pool and the 5G through link communication of terminal B is configured to use a second resource pool. When the first resource pool and the second resource pool are overlapped on the time domain or the frequency domain, the terminal with higher priority uses the overlapped part of the resource pools, and the terminal with lower priority does not use the overlapped part of the resource pools according to the priority related information.

The 4G through link communication of terminal a is configured to use a first set of subchannels of the third resource pool and the 5G through link communication of terminal B is configured to use a second set of subchannels of the third resource pool. When the first sub-channel set and the second sub-channel set overlap in the time domain or the frequency domain, the terminal with higher priority uses the overlapping sub-channels and the terminal with lower priority does not use the overlapping sub-channels according to the priority related information.

As shown in fig. 8, the vertical filled sub-channels of the solid line frame indicate overlapping portions (the solid line frame is filled with oblique lines) of the first resource pool (the solid line frame is not filled in the corresponding drawing) and the second resource pool (the solid line frame is filled in the corresponding drawing), and at this time, the terminals a and B use the overlapping portions of the resource pools according to the priority related information, and the terminals with higher priority do not use the overlapping portions of the resource pools.

As shown in fig. 9, the vertical-line boxes indicate overlapping portions of the first subchannel set (the non-filled subchannel set corresponding to the solid-line boxes in the figure) and the second subchannel set (the diagonally-filled subchannel set corresponding to the solid-line boxes in the figure), and at this time, the terminals a and B use overlapping subchannels according to the priority-related information, and the terminals with higher priority use overlapping subchannels, and the terminals with lower priority do not use overlapping subchannels.

The priority information may include system priority, terminal priority, service priority, etc.; the specific method comprises the following steps:

the priority information is the system priority, namely: 4G through link communication priority, or 5G through link communication priority. The priority information may be represented in 1 bit, such as: 0 indicates 4G through link communication priority, and 1 indicates 5G link communication priority.

The priority information is the terminal priority, namely: the through link communication of terminal a takes precedence, or the through link communication of terminal B takes precedence. The priority information may be represented in N1 bits (N1. Gtoreq.1), for example: when n1=2, 00 indicates that the through link communication priority of terminal a is 0, 11 indicates that the through link communication priority of terminal B is 3, and the smaller the priority value, the higher the priority.

The priority information is traffic priority, i.e.: the current traffic through link communication of terminal a takes precedence, or the current traffic through link communication of terminal B takes precedence. The priority information is represented by N2 bits (N2. Gtoreq.1), for example: when n2=3, 101 indicates that the current traffic through link communication priority of terminal a is 5, 010 indicates that the current traffic through link communication priority of terminal B is 2, and the smaller the priority value, the higher the priority.

If the priority of terminal a is the same as that of terminal B, then either terminal a or terminal B may change the time-frequency resources that the direct link communication is configured to use in accordance with the system (pre) configuration. For example, if the system is preconfigured with a high priority of terminal B, then when the priorities are the same, terminal a replaces the transmission resource (i.e., the configured time-frequency resource).

By adopting the indication method of the priority related information, the terminal A and the terminal B can configure the resource pool according to the priority related information, so that the 4G direct link communication of the terminal A and the 5G direct link communication of the terminal B can coexist, the probability of data packet transmission failure caused by resource collision is reduced, and the direct link data packet transmission success rate is improved.

Example 4 (example of indication information being SL DRX information);

this example relates to the following:

and the terminal A and the terminal B configure a resource pool according to the indication information. The indication information is SL DRX information; the terminal a and the terminal B specifically configure related resource information of the first resource pool, the second resource pool or the third resource pool according to the SL DRX information. The indication information is transmitted by the base station, terminal B or terminal C, or the indication information is preconfigured. Terminal a supports only 4G through links, while terminals B and C support both 4G through links and 5G through links. Specific:

1. When the 4G through link communication of the terminal a is configured to use the first resource pool and the 5G through link communication of the terminal B is configured to use the second resource pool, the first resource pool and the second resource pool are configured according to SL DRX information of the terminal B:

as shown in fig. 10, in a portion where the frequency domains of the first resource pool and the second resource pool overlap, all periods of the SL DRX inactivity period of the terminal B are configured as occupied periods of the first resource pool (corresponding to the solid line boxes with vertical line filled subchannels in the drawing), and all periods of the SL DRX inactivity period of the terminal B are configured as occupied periods of the second resource pool (corresponding to the solid line boxes with horizontal line filled subchannels in the drawing).

2. When the 4G through link communication of the terminal a is configured to use the first subchannel set of the third resource pool and the 5G through link communication of the terminal B is configured to use the second subchannel set of the third resource pool, the first subchannel set and the second subchannel set are configured according to the SL DRX information of the terminal B:

as shown in fig. 11, the entire period of the SL DRX inactivity period of the terminal B is configured as the occupied period of the first subchannel set (corresponding to the subchannel with no filling in the solid line box in the figure), and the entire period of the SL DRX inactivity period of the terminal B is configured as the occupied period of the second subchannel set (corresponding to the subchannel with diagonal filling in the solid line box in the figure).

By adopting the indication method of SL DRX information of the example, the terminal A and the terminal B can configure the resource pool according to the SL DRX information, so that 4G direct link communication of the terminal A and 5G direct link communication of the terminal B can coexist, the probability of failure of data packet transmission caused by resource collision is reduced, and the success rate of direct link data packet transmission is improved.

Example 5 (example 2 where the indication information is resource pool (pre) configuration information);

this example relates to the following:

terminal B configures SL DRX of terminal B according to the indication information. The indication information is resource pool (pre) configuration information. The indication information is transmitted by the base station, terminal B or terminal C, or the indication information is preconfigured. Terminal a supports only 4G through links, while terminals B and C support both 4G through links and 5G through links. Specific:

1. the 4G through link communication of terminal a is configured to use a first resource pool, the 5G through link communication of terminal B is configured to use a second resource pool, and SL DRX information of terminal B is configured according to the first resource pool and the second resource pool:

as shown in fig. 12, the first resource pool and the second resource pool are completely overlapped in the frequency domain, but occupy different subframes in the time domain. The whole period of the occupied period of the first resource pool is configured as the SL DRX inactive period of the terminal B (corresponding to the unfilled subchannel in the solid line box in the figure), and the whole period of the occupied period of the second resource pool is configured as the SL DRX active period of the terminal B (corresponding to the diagonally filled subchannel in the solid line box in the figure).

2. The 4G through link communication of terminal a is configured to use a first set of subchannels of a third resource pool, the 5G through link communication of terminal B is configured to use a second set of subchannels of the third resource pool, and SL DRX information of terminal B is configured according to the first set of subchannels and the second set of subchannels:

as shown in fig. 13, all of the occupied periods of the first sub-channel set are configured as SL DRX inactive periods of terminal B (corresponding to the solid line boxes in the figure without the padded sub-channels), and all of the occupied periods of the second sub-channel set are configured as SL DRX active periods of terminal B (corresponding to the solid line boxes in the figure with the diagonally padded sub-channels).

By adopting the indication method of the resource pool configuration information, the terminal B can configure SL DRX according to the resource pool (pre) configuration information, so that 4G through link communication of the terminal A and 5G through link communication of the terminal B can coexist, thereby reducing the probability of data packet transmission failure caused by resource collision and improving the success rate of through link data packet transmission.

Example 6 (others);

this example relates to the following:

terminal a and terminal B (pre) configure a resource pool or SL DRX according to the indication information. The indication information includes at least one item of information such as resource pool (pre) configuration information, priority related information, SL DRX information, etc. The indication information is transmitted by the base station, terminal B or terminal C, or the indication information is preconfigured. Terminal a supports only 4G through links, while terminals B and C support both 4G through links and 5G through links.

When the resource pool is configured, the first resource pool, the second resource pool, the first sub-channel set and/or the time slot or the subframe occupied by the second sub-channel set are configured in the form of a bitmap (bitmap). The specific examples are:

as shown in fig. 14, the first resource pool and the second resource pool are completely overlapped in the frequency domain, but occupy different subframes in the time domain; then the subframes occupied by the first resource pool in the time domain (corresponding to the unfilled subchannels in the solid line box in the figure) may be represented by bitmap 1, and the subframes occupied by the second resource pool in the time domain (corresponding to the diagonally filled subchannels in the solid line box in the figure) may be represented by bitmap 2, as follows:

bitmap 1: {1 10 0 0 1 10 0 0};

bitmap 2: {0 0 1 1 10 0 1 1 1};

the length of the bitmap is 10 bits, each bit corresponds to 1 subframe in one system frame period, when the bit is 1, the resource pool occupies the subframe, and when the bit is 0, the resource pool does not occupy the subframe. Other subframes may be repeated with the bitmap in the system frame period, but are not limited thereto.

By adopting the indication method of bitmap information, the terminal A and the terminal B can configure the resource pool according to the bitmap information, so that the 4G direct link communication of the terminal A and the 5G direct link communication of the terminal B can coexist, the probability of data packet transmission failure caused by resource collision is reduced, and the direct link data packet transmission success rate is improved.
