The character "/" generally indicates that the related objects are in an "or" relationship.

In the embodiment of this disclosure, the term "plurality" refers to two or more than two, and other quantifiers are similar to it.

The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only some of the embodiments of the present disclosure, not all of them. Based on the embodiments in this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of this disclosure.

When the distributed resource scheduling mode is adopted in the related art, the terminal independently selects the time-frequency resources used in direct link communication between it and other terminals. However, in the current network deployment, when terminals supporting different communication standards carry out direct link communication, terminals that only support 5G cannot sense that the direct link communication belongs to the 4th generation mobile communication (4G). Or the time-frequency resource occupancy of the direct link of the Long Term Evolution (LTE) communication standard, there will be a problem of collision between the resources occupied by the 4G direct link and the 5G direct link, resulting in mutual interference.

Therefore, how to effectively coordinate resources between 4G direct links and 5G direct links is an urgent technical issue in this field that needs to be solved.

In order to help understand the solutions of the embodiments of the present disclosure, the following will briefly introduce related concepts that may be involved in the present disclosure:

In the 5G V2X system, direct communication occurs between terminals on the sidelink. Before business data transmission, it is first necessary to determine the time-frequency resources used for direct link data transmission. The main criterion for determining time-frequency resources is to avoid collisions between time-frequency resources used by different terminals to avoid mutual interference. . In New Radio (NR) V2X, there are two resource scheduling modes. The first is the Mode1 resource allocation mode. The base station uniformly schedules the time-frequency resources used in direct link communication between terminals. The second mode is Mode2 resource allocation mode, in which the terminal independently selects the time-frequency resources used in direct link communication between terminals without the participation of the base station.

The Mode2 resource allocation mode in 5G V2X adopts distributed resource scheduling. Since there is no unified scheduling by the base station, the terminal (User Equipment, UE) needs to determine the resource occupancy of other UEs through the resource sensing mechanism, and make resource selections based on the resource sensing results. Compared with a completely random resource selection mechanism, the resource awareness mechanism can improve resource utilization, reduce collision probability, and improve system performance.

In related technologies, in the distributed resource scheduling mode, the terminal will exclude resources based on the results of its own resource sensing, that is, it will eliminate the conflicting resources it perceives. However, in current network deployment, 4G terminals and 5G terminals will exist at the same time. In this way, when there is direct link communication between 4G terminals and 4G terminals, and there is also direct link communication between 5G terminals and 5G terminals, due to These two direct link communications belong to different communication standards, so they cannot sense each other, and the resources occupied by the 4G direct link and the 5G direct link collide, causing mutual interference.

Specifically, the above communication format refers to the 4G V2X data packet format and the 5G V2X data packet format. The two data packet formats are different. The terminal needs to decode the V2X data packet when sensing. Due to the different formats, the V2X terminal that only supports the 5G communication standard cannot decode the 4G V2X data packet, so it cannot sense the other party.

V2X terminals that only support the 5G communication standard cannot correspond to 4G V2X terminals when calculating the Reference Signal Receiving Power (RSRP) and the Received Signal Strength Indication (RSSI) of the received signal. The signal is excluded because the V2X terminal that only supports the 5G communication standard needs to first decode the V2X data packet and obtain the resource reservation information in the data packet before it can learn the interference resources used by the other party. However, due to different formats, V2X terminals that only support 5G communication standards cannot decode V2X data packets in the 4G network, so they cannot sense the other party. 5G V2X is also called NR V2X.

When using Mode2 for resource allocation on 5G V2X direct links, the specific steps include:

(1) Resource awareness: Resource awareness means that the terminal determines whether the resource is used by other terminals based on the RSRP strength of the resource. In the resource sensing process, it is necessary to consider the different characteristics of periodic services and non-periodic services in mixed service scenarios in NR V2X applications, as well as the impact of service types on resource sensing results. At the same time, appropriate resource-aware configuration needs to be performed based on the time-frequency resource granularity in the physical channel, resource pool settings and other information. The resource sensing window refers to the time window for the terminal to sense resources.

(2) Resource exclusion: The main purpose of resource exclusion is to exclude resources that are not available for resource selection within the resource selection window based on the sensing results, such as excluding the time-frequency resources required by the terminal to receive data (NR V2X terminal uses half-duplex method to send and receive data, half-duplex means that the terminal cannot simultaneously Send and receive data) to form a candidate resource set, reduce the probability of resource collision, and improve reliability.

(3) Resource selection: The resource selection mechanism is to select the appropriate transmission time and frequency resources for the transport block (TB) of the business packet to be sent from the candidate resource set. It needs to consider the priority, delay, business packet size, and transmission reliability requirements for resource selection. The resource selection window refers to the time window for the terminal to select resources.

The 5G V2X direct link uses Mode2 for resource allocation, which specifically uses a distributed resource scheduling mechanism. Since there is no unified scheduling by the base station, the terminal UE needs to determine the resource occupancy of other UEs through the resource sensing mechanism, and make resource selections based on the resource sensing results. Compared with a completely random resource selection mechanism, the resource awareness mechanism can improve resource utilization, reduce collision probability, and improve system performance. The Mode4 resource scheduling mode of the direct link in the 4G network also adopts the distributed resource scheduling mechanism described above.

When the service arrives, the terminal receives the data packet within the resource awareness window and decodes the sidelink control information (SCI). Resources that fall within the resource selection window and whose reference signal received power RSRP is greater than the RSRP threshold need to be excluded. , the remaining resources are candidate resources, and then sorted according to the received signal strength indicator RSSI, and randomly selected from the 20% candidate resources with the smallest RSSI in the sorting results, or directly randomly select the resources required for direct link transmission from all candidate resources . The length of the resource selection window can be configured as the maximum period of the service.

Before sending data on the direct link, the terminal first performs resource sensing and selects resources based on the results of resource sensing. This mechanism can avoid collisions to a certain extent. Figure 1 is a schematic diagram of resource sensing and resource selection in related technologies. As shown in Figure 1, when the terminal selects resources, it will exclude perceived conflicting resources.

Because of the problems existing in the above related technologies, the present disclosure proposes a method of transmitting indication information of respective resource occupation information between 4G terminals and 5G terminals, thereby effectively assisting resource coordination between 4G direct links and 5G direct links.

Figure 2 is one of the flow diagrams of an information processing method provided by an embodiment of the present disclosure. The method can be applied to the first terminal. As shown in Figure 2, the method includes:

Step 201: Send the first instruction information to the second terminal;

Wherein, the first indication information is used to indicate the resources of the first through link and/or the second through link. Source occupancy information;

Specifically, the first terminal is a terminal that supports a first direct link and a second direct link, where the first direct link and the second direct link respectively represent direct links under different communication standards, and the second direct link The direct link is a higher-level communication standard than the first direct link. Advanced here means that according to the development of communication technology, the later the communication technology appears, the more advanced it is. The first direct link can be a currently supported direct link, such as a 4G direct link, or a 5G direct link, and the second direct link can be a future supported direct link, such as a 5G direct link, or a new generation Direct link under communication format. This is mainly explained by taking the first direct link as a 4G direct link and the second direct link as a 5G direct link as an example.

The first terminal supports both 4G direct link and 5G direct link. It can learn the resources of the 4G direct link occupied by itself, and can also obtain the resources of the 4G direct link occupied by other terminals. In the same way, the first terminal can also learn the resources occupied by itself. 5G direct link resources, and can also obtain the 5G direct link resources occupied by other terminals.

By knowing the resource occupancy of the above-mentioned 4G direct link and the 5G direct link and sending it to the second terminal that supports the 5G direct link, the second terminal can determine the resources available for its own 5G direct link.

The information processing method provided by the embodiment of the present disclosure sends the resource occupation information of the first direct link and/or the second direct link to the second terminal that supports the second direct link, so that the second terminal can determine its The time and frequency resources available for the second direct link. This reduces the probability of data packet transmission failure due to collision of time-frequency resources corresponding to the first direct link and the second direct link, and improves the success rate of direct link data packet transmission.

Resource aware information;

Specifically, when the first terminal sends the occupancy status of the resources of the above-mentioned 4G direct link and the resource of the 5G direct link, it may specifically use different indication information to represent the resource sensing information directly sensed by the first terminal, or the first terminal The resource information occupied by the 4G direct link determined by the terminal, or the resource information not occupied by the 4G direct link determined by the first terminal, or the conflict between the resources occupied by the 4G direct link and the 5G direct link determined by the first terminal , or any combination of the above information. The above resources usually refer to time-frequency resources in the network. Of course, depending on the development of the network, they may also refer to resources corresponding to the time domain, frequency domain and air domain (space domain). The first indication information is determined according to the above one or more indication information and sent to the second terminal to more flexibly indicate the time-frequency resources occupied by the terminal or the unoccupied time-frequency resources so that the second terminal can obtain the information from the above indication. The information determines the time and frequency resources available for its 5G direct link.

The resource sensing information directly sensed by the first terminal is mainly directly obtained information without calculation and processing.

The resource information occupied by the 4G direct link determined by the first terminal, or the unoccupied resource information, mainly refers to the resources occupied by the 4G direct link that the first terminal perceives itself to occupy, as well as the 4G direct link that can be perceived by other terminals. The resources occupied by the link. The unoccupied resource information of the 4G direct link determined by the first terminal is similar to the resource information occupied by the 4G direct link.

The conflict between the resources occupied by the 4G direct link and the 5G direct link determined by the first terminal mainly refers to the fact that the first terminal senses the occupancy of the 4G direct link and the occupancy of the 5G direct link, and combines the two The information is certain.

The information processing method provided by the embodiment of the present disclosure uses resource sensing information, time-frequency resources occupied by the first direct link, and relevant information about conflicts in the time-frequency resources occupied by the first direct link and the second direct link. The first indication information composed of one or more of the above is sent to the second terminal supporting the second direct link, so that the second terminal can determine the time-frequency resources available for its second direct link. A more flexible indication of the resource information occupied by the first direct link and the resource information occupied by the second direct link is conducive to the second terminal to determine the available resources of its second direct link through various methods, thereby reducing the cost of the first direct link. The time-frequency resources corresponding to the direct link and the second direct link collide, resulting in the probability of data packet transmission failure and improving the success rate of data packet transmission on the direct link.

Indicates whether the occupied time-frequency resource or the occupied time-frequency resource comes from the first direct link (4G direct link). This indication information is represented by 1 bit. For example, when the value of 1 bit is 0, it means that the time-frequency resource is From the 4G direct link, when the value of 1 bit is 1, it means that the time-frequency resource is not occupied by the 4G direct link, and vice versa;

The indicated time-frequency resource information is the time-frequency resource information occupied by the 4G direct link or the time-frequency resource information not occupied by the 4G direct link. The indication information is represented by 1 bit. For example, when the value of 1 bit is 0, it means that this time The frequency resource is the time-frequency resource information not occupied by the 4G direct link. When the value of 1 bit is 1, it means that the time-frequency resource is the time-frequency resource information occupied by the 4G direct link, and vice versa;

The indication information is expressed in N bits.

For example, when the corresponding value of the 2 bits is 1, it means that the resource sensing information is 4G Sensing information of the time-frequency resources of the direct link. When the corresponding value of the 2 bits is 2, it indicates that the resource sensing information is the sensing information of the time-frequency resources of the 5G direct link. When the corresponding value of the 2 bits is 3, it indicates that the resource is The sensing information includes both the sensing information of the time-frequency resources of the 4G direct link and the sensing information of the time-frequency resources of the 5G direct link. Of course, it can also be based on the case where the high-order bit of the 2 bits is 1 and the low-order bit is 0, which means that the resource sensing information is the sensing information of the time-frequency resource of the 4G direct link. The high-order bit of the 2 bits is 0 and the low-order bit is 1. Below, it indicates that the resource sensing information is the sensing information of the time-frequency resources of the 5G direct link.

The sensing information indicating the time-frequency resources of the 4G direct link is periodic or aperiodic. In the case of periodicity, the value of the period can be set to 1 second, which is equivalent to full sensing, that is, the occupancy of the time-frequency resources of the 4G direct link is sensed every second. The value of the period is set to set to For durations less than 24 hours, such as 5 hours, 30 minutes, and 45 seconds, it corresponds to periodic partial sensing; for non-periodic situations, it corresponds to continuous sensing of the 4G direct link for a certain period of time.

Optionally, the resource is determined based on whether the third terminal supporting the first direct link and the fourth terminal supporting the second direct link belong to the same resource pool and the resource awareness information. Pool instructions, including:

If they belong to different resource pools, determine based on the sensing information indicating the time-frequency resources occupied by the second direct link indicated by the resource sensing information and the resource pool to which the fourth terminal belongs. The resource pool indication information;

If they belong to the same resource pool, based on the sensing information indicating the time-frequency resources occupied by the first direct link and/or the sensing information of the time-frequency resources occupied by the second direct link indicated by the resource sensing information information to determine the resource pool indication information.

Specifically, when the first terminal determines that the third terminal and the fourth terminal belong to different resource pools, it means that the fourth terminal can only use resources in the resource pool belonging to the fourth terminal. Then, according to the sensing information indicating the time-frequency resources occupied by the 5G direct link indicated by the resource sensing information, and the resource pool to which the fourth terminal belongs, the indication information of the resource pool of the available time-frequency resources of the 5G direct link of the second terminal is determined. , that is, the resource pool indication information, and is sent to the second terminal through the first indication information.

When it is determined that the third terminal and the fourth terminal belong to the same resource pool, the first terminal needs to determine the first indication based on at least one of the resource awareness information of the 4G direct link and the resource awareness information of the 5G direct link.

Collection of information.

2. When the third terminal and the fourth terminal belong to the same resource pool:

The third terminal and the fourth terminal belong to the same resource pool and are regarded as the basic resource pool.

When only the resource sensing information of the 4G direct link is sensed, the time-frequency resources occupied by the 4G direct link are determined, and further the time-frequency resources in the above basic resource pool other than the time-frequency resources occupied by the 4G direct link can be determined. All resources or part of the resources are used as the resource pool of time-frequency resources available for the 5G direct link of the second terminal. Then, the above resource pool indication information includes the basic resource pool except 4G.

Then, the above resource pool indication information is a set of indication information corresponding to all or part of the resources in the basic resource pool except the joint sensing resources.

Specifically, when the first terminal sends the first indication information to the second terminal, it may be sent directly through a direct link between the two terminals, or forwarded to the second terminal through the base station.

If the first terminal and the second terminal are within the coverage of the same base station, then the first terminal forwards the first indication information to the second terminal through the base station to which they are both connected;

If the first terminal and the second terminal are not within the coverage of the same base station, the first terminal sends the first indication information to the second terminal through the direct link between the two.

The first terminal here includes a 4G module and a 5G module. The 4G module is mainly used to support 4G direct links, or sense the time and frequency resources occupied by 4G direct links; the 5G module is mainly used to support 5G direct links, or sense 5G direct links.

When the first terminal and the second terminal are within the coverage of the same base station, the first terminal uses 4G The module senses the time-frequency resource information occupied by the 4G direct link and sends other indication information included in the first indication information to the same base station, and forwards it to the second terminal through the base station.

When the first terminal and the second terminal are not within the coverage of the same base station and the second terminal only includes a 5G module, the 4G module of the first terminal senses the time-frequency resource information occupied by the 4G direct link and sends it to the third terminal. The 5G module of a terminal, and the 5G module of the first terminal will also sense the time-frequency resource information occupied by the 5G direct link, and finally use the 5G module of the first terminal to combine the time-frequency resource information occupied by the 4G direct link and the 5G direct link. The time-frequency resource information occupied by the channel and other indication information included in the first indication information are sent to the 5G module of the second terminal.

In addition, there are cases where the first terminal includes a 5G module and a 4G module. Due to the hidden node problem, the first terminal fails to perceive the time-frequency resource information occupied by the 4G direct link. Therefore, the first terminal perceives the time-frequency resource information occupied by the 4G module and the 5G module respectively. The time-frequency resource information occupied by the 5G direct link and other indication information included in the first indication information are sent to the 5G module of the second terminal.

Based on the resource awareness window, obtain the first signal sent by the third terminal; the first signal is used to determine the time-frequency resource occupied by the first direct link;

And/or, based on the resource awareness window, obtain the second signal sent by the second terminal; the second signal is used to determine the time-frequency resource occupied by the second direct link;

Specifically, all terminals can obtain the first signal sent by the third terminal within the resource awareness window through the 4G module to determine the time-frequency resource information occupied by the 4G direct link. The first signal is usually scheduling allocation information (Scheduling information). Assignment, SA).

Similarly, the 5G module can be used to obtain the second signal sent by the fourth terminal within the resource sensing window to determine the time-frequency resource information occupied by the 5G direct link. The second signal is usually the direct link control information SCI.

A first terminal including a 4G module and a 5G module, where information of the 4G module and the 5G module can be communicated with each other. However, the second terminal including only the 5G module cannot obtain the information corresponding to the 4G module, or due to the hidden node, the second terminal including the 4G module and the 5G module cannot obtain the information corresponding to the 4G module.

In this disclosure, the acquisition of resource sensing information mainly includes the sensing information of the time-frequency resources occupied by the 4G direct link. The time-frequency resources occupied by the 4G direct link are determined by obtaining the SA signal sent by the third terminal.

It also includes the sensing information of the time-frequency resources occupied by the 5G direct link, which is determined through the SCI signal sent by the fourth terminal to determine the time-frequency resources occupied by the 5G direct link.

The information processing method provided by the embodiment of the present disclosure uses resource sensing information, time-frequency resources occupied by the first direct link, and relevant information about conflicts in the time-frequency resources occupied by the first direct link and the second direct link. Sent to the second terminal supporting the second direct link, so that the second terminal can determine the time-frequency resources available for its second direct link. This reduces the probability of data packet transmission failure due to collision of time-frequency resources corresponding to the first direct link and the second direct link, and improves the success rate of direct link data packet transmission.

The first terminal supports both 4G direct link and 5G direct link. It can learn the resources of the 4G direct link occupied by itself, and can also obtain the resources of the 4G direct link occupied by other terminals; similarly, the first terminal The terminal can also learn the resources of the 5G direct link occupied by itself, and can also obtain the resources of the 5G direct link occupied by other terminals.

The first terminal learns the occupancy status of the resources of the above-mentioned 4G direct link and the 5G direct link and sends it to the second terminal that supports the 5G direct link. Then the second terminal can determine that its own 5G direct link is available. resource.

Resource aware information;

The resource information occupied by the 4G direct link determined by the first terminal, or the unoccupied resource information, It mainly refers to the resources occupied by the 4G direct link that the first terminal perceives itself to occupy, and the resources occupied by the 4G direct link that other terminals can perceive. The unoccupied resource information of the 4G direct link determined by the first terminal is similar to the resource information occupied by the 4G direct link.

After the second terminal receives the first indication information sent by the first terminal, the second terminal determines the resource awareness information included in the first indication information, the indication information of the time-frequency resource occupied by the first direct link, and the first direct communication link. Determine which time-frequency resource information is based on one or more of the indication information of the time-frequency resources not occupied by the link and the indication information of the time-frequency resource conflict between the first direct link and the second direct link. It can be used as available time-frequency resources for its own 5G direct link.

Based on the resource awareness information included in the first indication information, it is determined that the third terminal supporting the first direct link indicated by the resource awareness information and the fourth terminal supporting the second direct link belong to different resource pool, or belong to the same resource pool;

If it belongs to the same resource pool, it belongs to the first direct link based on the resource awareness information indication. The sensing information of the time-frequency resources occupied by the second direct link and/or the sensing information of the time-frequency resources occupied by the second direct link determines the time-frequency resources available for the second direct link of the second terminal.

Specifically, the second terminal receives the first indication information sent by the first terminal, determines whether the first indication information includes resource awareness information, and if it includes resource awareness information, further determines whether the third terminal indicated by the resource awareness information Whether the third terminal and the fourth terminal belong to the same resource pool; that is, determine whether the third terminal and the fourth terminal belong to the same resource pool.

When the third terminal and the fourth terminal belong to different resource pools, it means that the fourth terminal can only use resources in the resource pool belonging to the fourth terminal. Then, according to the sensing information indicating the time-frequency resources occupied by the 5G direct link indicated by the resource sensing information, and the resource pool to which the fourth terminal belongs, the resource pool of time-frequency resources available for the 5G direct link of the second terminal is determined;

When the third terminal and the fourth terminal belong to the same resource pool, the second terminal is determined based on at least one of the resource awareness information of the 4G direct link and the resource awareness information of the 5G direct link indicated by the first indication information. The resource pool of time-frequency resources available for the 5G direct link; that is, through the sensing information of the time-frequency resources occupied by the first direct link and the sensing information of the time-frequency resources occupied by the second direct link, the third direct-through link is determined. A resource pool of time-frequency resources available for the 5G direct link of the second terminal.

Specifically, when the received first indication information indicates that the third terminal and the fourth terminal belong to different resource pools:

Determine all or part of the time-frequency resources in the resource pool B except the first time-frequency resource. The time-frequency resources are time-frequency resources available for the second direct link of the second terminal, that is, a resource pool of time-frequency resources available for the 5G direct link of the second terminal.

Specifically, when the received first indication information determines that the third terminal and the fourth terminal belong to the same resource pool, the second terminal is based on the sensing information of the time-frequency resources occupied by the first direct link and/or belongs to The sensing information of the time-frequency resources occupied by the second direct link determines the time-frequency resources available for the second direct link of the second terminal. The corresponding method is as follows:

The same resource pool to which the third terminal and the fourth terminal belong is used as the basic resource pool.

In the case where it is determined that only the resource sensing information including the 4G direct link is indicated, the time-frequency resources occupied by the 4G direct link are determined, and further, in addition to the time-frequency resources occupied by the 4G direct link in the above basic resource pool, All or part of the resources are used as a resource pool of time-frequency resources available for the 5G direct link of the second terminal.

When it is determined that the indication includes both the resource sensing information of the 4G direct link and the resource sensing information of the 5G direct link, determine the time-frequency resources occupied by the 4G direct link and the time-frequency resources occupied by the 5G direct link, as Joint sensing resources; further determine that among the above basic resource pools, in addition to joint All or part of the resources other than the sensing resources serve as a resource pool of time-frequency resources available for the 5G direct link of the second terminal.

Optionally, determining the time-frequency resources available for the second direct link of the second terminal based on the received first indication information further includes:

Specifically, when the second terminal receives the resource pool indication information in the first indication information sent by the first terminal, it can directly determine which time-frequency resources are available based on the resource pool indication information, and select some or all of them.

Through the multiple indication information included in the first indication information, the second terminal can determine the available time-frequency resources of the 5G direct link of the second terminal through a combination of the multiple indication information, or directly through one of the indication information.

The information processing method provided by the present disclosure is further introduced below with several specific examples. Among them, the third terminal is also called a 4G terminal, and the fourth terminal is also called a 5G terminal.

Example 1: The first terminal (Terminal B) directly sends the first indication information through the direct link or sends the first indication information to the second terminal (Terminal A) through a commonly connected base station.

Terminal A determines its available 5G direct link time-frequency resource candidate set according to the first indication information. The first indication information includes 4G direct link resource indication information, 4G direct link resource occupied time-frequency resource information, 4G direct link Unoccupied time-frequency resource information, 4G and 5G direct link resource conflict indication information, priority-related information, resource awareness information, Semi-Persistent Scheduling (SPS) information, Channel Busy Ratio (CBR) ) information and channel occupancy ratio (Channel Occupancy Ratio, CR) information. The first indication information is sent by terminal B. Terminal A supports at least 5G direct link, and terminal B also supports 4G. Direct link and 5G direct link.

Specifically, when the 4G direct link and the 5G direct link share time-frequency resources or are in the same resource pool, in order to avoid resource collision between the 4G direct link and the 5G direct link, the 4G direct link needs to be The resources are sent to the 5G terminal, so that when the 5G terminal determines its available 5G direct link time-frequency resource candidate set, the time-frequency resources occupied by these 4G direct links are excluded.

Terminal A and terminal B are both 5G terminals and have 5G modules (4G module refers to 4G V2X module, 5G module refers to 5G V2X module). Terminal A is a terminal that has at least a 5G module and supports at least a 5G direct link; terminal A may or may not support a 4G direct link. Terminal B is a terminal that has both a 4G module and a 5G module and supports both a 4G direct link and a 5G direct link.

Terminal B obtains the time-frequency resource information occupied by the 4G direct link, the time-frequency resource information not occupied by the 4G direct link, and the resource conflict indication information of 4G and 5G direct links through its 4G direct link module, and then forwards it internally to terminal B Give it a 5G pass-through link module. Then, terminal B sends the obtained information related to the 4G direct link resources to terminal A through the 5G direct link module.

Figure 4 is one of the implementation flow diagrams for the first terminal to send the first indication information provided by the embodiment of the present disclosure. As shown in Figure 4, terminal A and terminal B are within the coverage of the same base station. When terminal A is within the coverage , terminal B sends the first indication information composed of the 4G direct link resource related information obtained through its 4G direct link module and other indication information to base station 1, and base station 1 then sends the first indication information to terminal A.

Figure 5 is the second schematic flow diagram of the implementation of the first terminal sending the first instruction information provided by the embodiment of the present disclosure. As shown in Figure 5, terminal A and terminal B are not within the coverage of the same base station, and terminal A only includes a 5G module. Since terminal A does not have a 4G module, it cannot sense the time-frequency resource information occupied by the 4G direct link. Therefore, terminal B uses the 5G direct link to combine these 4G direct link resource related information and other indication information into the first indication information. Send the terminal A, so that the terminal A obtains the first indication information.

Figure 6 is a third schematic flowchart of the implementation of the first terminal sending the first instruction information provided by the embodiment of the present disclosure. As shown in Figure 6, terminal A and terminal B are not within the coverage of the same base station, and terminal A includes a 4G module and 5G module, although terminal A has a 4G module, due to the hidden node problem, Terminal A fails to sense the time-frequency resource information occupied by the 4G direct link, so terminal B uses the 5G direct link to send the first indication information composed of these 4G direct link resource related information and other indication information to terminal A, so that the terminal A obtains the first instruction information.

Example 2: The first indication information sent by the first terminal (Terminal B) includes the time-frequency resource information occupied by the 4G direct link

As shown in Figure 7, the 4G terminal sends an SA on the No. 3 time slot of the No. 3 sub-channel. The SA Indicates that the resources on time slot No. 7 of sub-channel 2 will be used by the 4G terminal to send data. Terminal B monitors the SA sent by the 4G terminal in time slot No. 5 and learns the 4G direct link resource occupancy information. In this way, terminal B sends the 4G resource occupancy information to terminal A in time slot No. 5. Terminal A will When selecting time-frequency resources for time slot No. 1, sub-channel No. 1 is selected to avoid sub-channel No. 2 occupied by 4G terminals. The number sub-channel avoids resource conflicts between the time-frequency resources used by terminal A and the time-frequency resources used by the 4G terminal.

Note: Terminal B may also obtain the 4G direct link resource occupation information through other methods, and then indicate it to Terminal A. For example, terminal B receives indication information from the base station or other terminals, thereby obtaining 4G direct link resource occupation information.

When the first indication information includes information indicating whether the time-frequency resource comes from the 4G direct link, the indication information is used to indicate whether the time-frequency resource information indicated in the first indication information comes from the 4G direct link; the indication information Represented by 1 bit;

When the first indication information includes information indicating the time-frequency resources occupied by the first direct link, the indication information indicates the specific time-frequency resources occupied by the 4G direct link, that is, sub-number 2 shown in Figure 7 Resources on channel 7 time slot.

Using this method of sending first indication information, terminal A can obtain the resource occupancy status of the 4G direct link, so that terminal A can determine its available 5G direct link time-frequency resource candidate set based on the first indication information, so that 4G direct link Link communication and 5G direct link communication can coexist, thereby reducing the probability of data packet transmission failure caused by collision of 4G and 5G direct link resources and improving the success rate of direct link data packet transmission. Since specific time-frequency resource information is indicated, higher signaling overhead may be incurred.

As shown in Figure 8, the 4G terminal sends an SA on the No. 3 time slot of the No. 3 sub-channel. The SA indicates that the resources on time slot No. 7 of sub-channel 2 will be used by the 4G terminal to send data. Terminal B monitors the SA sent by the 4G terminal in time slot No. 5 and learns the 4G direct link resource occupancy information. In this way, terminal B sends the 4G resource occupancy information to terminal A in time slot No. 5. Terminal A will When selecting time-frequency resources for time slot No. 1, sub-channel No. 1 is selected to avoid sub-channel No. 2 occupied by 4G terminals, thus avoiding the conflict between the time-frequency resources used by terminal A and the time-frequency resources used by 4G terminals. Resource conflicts occur.

When the first indication information is time-frequency resource information that is not occupied by the 4G direct link, it indicates the specific time-frequency resources that are not occupied by the 4G direct link, that is, No. 1, No. 3, and No. 4 as shown in Figure 8 The resources of the channel in time slot No. 7.

Figure 9 is one of the schematic diagrams in which the first indication information provided by an embodiment of the present disclosure includes potential resource conflict indication information for 4G and 5G direct links. As shown in Figure 9, when the 5G module of terminal A is on sub-channel No. 1 and No. 2 The SCI is sent on time slot No. 3 of sub-channel 3, and the 4G terminal sends SA on time slot No. 3 of sub-channel 3. Both the SCI and SA indicate that the resources on time slot No. 6 of sub-channel 2 will be used by terminal A and the 4G terminal to send data respectively. , so a resource conflict occurs. Terminal B monitors the SCI sent by terminal A and the SA sent by the 4G terminal in time slot No. 5, and learns the resource conflict information. In this way, terminal B sends the resource conflict information to terminal A in time slot No. 5. Terminal A Transmission resources will be replaced to avoid resource conflicts. Since terminal B sends the resource conflict information to terminal A before the resource conflict occurs, this is a potential resource conflict.

Note: Terminal B may also obtain the 4G and 5G direct link resource conflict indication information through other methods, and then indicate it to Terminal A. For example, terminal B receives the indication information sent directly by other terminals or the indication information sent by other terminals forwarded by the base station, thereby obtaining the 4G and 5G direct link resource conflict indication information.

Using this method of sending first indication information, terminal A can obtain potential 4G and 5G direct link resource conflicts, so that terminal A can determine its available 5G direct link time-frequency resource candidate set based on the first indication information or Data is retransmitted so that 4G direct link communication and 5G direct link communication can coexist, thereby reducing the probability of data packet transmission failure caused by 4G and 5G direct link resource collisions and improving the success rate of direct link data packet transmission. And since it only indicates whether there is In resource conflicts, the signaling overhead is small, but because no specific time-frequency resource information is indicated, the amount of information it can bring is small.

Example 5: The first indication information is the resource conflict indication information detected on the 4G and 5G direct link.

Terminal A determines its available 5G direct link time-frequency resource candidate set according to the first indication information, and the first indication information includes the detected 4G and 5G direct link resource conflict indication information. The first indication information is sent by the base station or terminal B. Terminal A supports at least 5G direct link, and terminal B supports both 4G direct link and 5G direct link.

The first indication information includes 4G and 5G direct link resource conflict indication information, indicating that there is a resource conflict between the 5G direct link resources currently used by terminal A and the 4G direct link resources used by other terminals.

The first indication information includes detected 4G and 5G direct link resource conflict information, indicating a resource conflict that has occurred between the 4G direct link and the 5G direct link.

Figure 10 is a second schematic diagram in which the first indication information provided by an embodiment of the present disclosure includes potential resource conflict indication information for 4G and 5G direct links. As shown in Figure 10, terminal B monitors terminal A in time slot No. 7. The SCI sent by the 5G module and the SA sent by the 4G terminal learn the resource conflict information. In this way, the 5G module of terminal B sends the resource conflict information to terminal A in time slot No. 7. The 5G module and 4G module of terminal A will replace the transmission resources and then retransmit the data respectively. Since the 5G module of terminal B sends the resource conflict information to terminal A after the resource conflict occurs, this is a detected resource conflict.

Note: Terminal B may also obtain the 4G and 5G direct link resource conflict indication information through other methods, and then indicate it to Terminal A. For example, terminal B receives indication information from the base station or other terminals, thereby obtaining 4G and 5G direct link resource conflict indication information.

Example 6: The first indication information is resource awareness information

Terminal A determines its available 5G direct link time-frequency resource candidate set according to the first indication information, and the first indication information includes resource awareness information.

Configure all or part of the resources in the resource pool to which the 5G terminal belongs, except for the resources occupied by the perceived 5G direct link, as occupied resources of the first resource pool;

When the 4G terminal and the 5G terminal are in the same resource pool, the 5G direct link communication of terminal A occupies the indication information of the first resource pool. According to the resource sensing information of the 4G direct link and the 5G direct link in the first indication information, At least one piece of information in the resource awareness information determines the first resource pool, including at least one of the following:

When the first indication information includes the resource sensing information of the 4G direct link and the resource sensing information of the 5G direct link, the resources occupied by the perceived 4G direct link and the 5G direct link are added to the basic resource pool. All or part of the resources outside the first resource pool are configured as occupied resources of the first resource pool.

Figure 11 is one of the schematic diagrams in which the first indication information includes resource awareness information provided by an embodiment of the present disclosure. As shown in Figure 11, as shown, the 4G terminal sends an SA on the No. 3 time slot of the No. 3 sub-channel, and the SA indicates The resources on time slot No. 6 of sub-channel 2 will be used by the 4G terminal to send data. In this way, terminal B senses the SA sent by the 4G terminal in time slot No. 5 and learns the resource occupation information. This For example, terminal B sends the resource awareness information to terminal A in time slot No. 5, and terminal A will change the transmission resources to avoid resource conflicts.

Figure 12 is a second schematic diagram in which the first indication information provided by an embodiment of the present disclosure includes resource awareness information. As shown in Figure 12, the 5G terminal sends SCI on sub-channel No. 1 and time slot No. 2, and the 4G terminal transmits SCI on sub-channel No. 3. SA is sent on time slot No. 3. The SCI and SA respectively indicate that the resources on time slot No. 6 of sub-channel 1 and time slot No. 2 of sub-channel will be used by 5G terminals and 4G terminals respectively to send data. In this way, the terminal B senses the SCI and SA sent by the 5G terminal and the 4G terminal respectively in time slot No. 5, and learns the resource occupation information. In this way, terminal B sends this resource sensing information to terminal A in time slot No. 5, and terminal A will change the transmission resources. , to avoid resource conflicts.
