When the distributed resource scheduling mode is adopted in the relevant technology, the terminal autonomously selects the time and frequency resources used in the direct link communication between it and other terminals. However, in the current network deployment, when the direct link communication is carried out between terminals supporting different communication standards, the terminal that only supports 5G cannot perceive the time and frequency resource occupation of the direct link communication belonging to the 4th generation mobile communication (4G) or Long Term Evolution (LTE) communication standard, which will cause the resources occupied by the 4G direct link and the 5G direct link to collide and cause mutual interference.

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

In order to help understand the scheme of the embodiment of the present invention, the following will briefly introduce the relevant concepts that the present invention may belong to: In the 5G V2X system, the terminals communicate directly with each other on the sidelink. Before transmitting business data, it is necessary to first determine the time-frequency resources used for the sidelink data transmission. The main criterion for determining the time-frequency resources is to avoid collisions between the time-frequency resources used by different terminals to avoid mutual interference. In the New Radio (NR) V2X (Vehicle to everything), there are two resource scheduling modes. The first is the Mode 1 resource configuration mode, in which the base station uniformly schedules the time and frequency resources used in the direct link communication between terminals. The second is the Mode 2 resource configuration mode, in which the terminal autonomously selects the time and frequency resources used in the direct link communication between terminals without the participation of the base station.

The Mode 2 resource configuration mode in 5G V2X adopts distributed resource scheduling. Since there is no unified scheduling of the base station, the terminal (User Equipment, UE) needs to determine the resource occupancy of other UEs through the resource sensing mechanism and select resources based on the resource sensing results. Compared with the completely random resource selection mechanism, the resource sensing mechanism can improve resource utilization, reduce the probability of collision, and improve system performance.

In the relevant technology, in the distributed resource scheduling mode, the terminal will exclude resources according to the results of its own resource perception, that is, exclude the conflicting resources it perceives. However, in the current network deployment, 4G terminals and 5G terminals exist at the same time. In this way, when 4G terminals communicate with each other through a direct link, and 5G terminals communicate with each other through a direct link, since these two direct link communications belong to different communication standards, they cannot perceive each other, and the resources occupied by the 4G direct link and the 5G direct link will collide and cause mutual interference.

Specifically, the above communication standards refer to the 4G V2X data packet format and the 5G V2X data packet format. The two data packet formats are different, and 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.

When calculating the reference signal receiving power (RSRP) and received signal strength indication (RSSI) of the received signal, the V2X terminal that only supports the 5G communication standard cannot exclude the corresponding signal of the 4G V2X terminal. The reason is that when the V2X terminal that only supports the 5G communication standard perceives, it first needs to decode the V2X data packet and obtain the resource reservation information in the data packet to know the interference resources used by the other party. However, due to the different formats, the V2X terminal that only supports the 5G communication standard cannot decode the V2X data packet in the 4G network, so it cannot perceive the other party. 5G V2X is also called NR V2X.

When the 5G V2X direct link adopts Mode 2 for resource configuration, the specific steps include: (1) Resource perception: Resource perception means that the terminal determines whether the resource is used by other terminals based on the RSRP strength of a resource. In the resource perception process, it is necessary to consider the different characteristics of periodic services and non-periodic services in the hybrid service scenarios in NR V2X applications, as well as the impact of service types on resource perception results. At the same time, it is also necessary to perform appropriate resource perception configuration based on information such as the time-frequency resource details in the physical channel and resource pool settings. Resource perception window refers to the time window in which the terminal performs resource perception; (2) Resource exclusion: The main purpose of resource exclusion is to exclude resources that are not available for resource selection in the resource selection window based on the perception results, such as excluding the time-frequency resources required for the terminal to receive data (NR V2X terminals transmit and receive data in half-duplex mode, and half-duplex means that the terminal cannot transmit and receive data at the same time), forming a candidate resource set, reducing the probability of resource collision, and improving reliability; (3) Resource selection: The resource selection mechanism is to select appropriate transmission time-frequency resources for the transport block (TB) of the service packet to be sent from the candidate resource set. Resource selection needs to consider the service priority, latency, service packet size, and transmission reliability requirements. The resource selection window refers to the time window during which the terminal performs resource selection.

The 5G V2X direct link uses Mode2 for resource allocation, which specifically adopts a distributed resource scheduling mechanism. Since there is no unified scheduling of base stations, the terminal UE needs to determine the resource occupancy of other UEs through the resource perception mechanism and select resources based on the resource perception results. Compared with the completely random resource selection mechanism, the resource perception mechanism can improve resource utilization, reduce the probability of collision, 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 a service arrives, the terminal receives data packets within the resource perception 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 value need to be excluded. The remaining resources are candidate resources, which are then sorted by received signal strength indication RSSI. The resources required for the direct link transmission are randomly selected from the 20% of candidate resources with the smallest RSSI in the sorting results, or directly randomly selected 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 senses resources 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 the perceived conflicting resources.

Due to the problems existing in the above-mentioned related technologies, the present invention proposes an indication information for transmitting respective resource occupancy information between a 4G terminal and a 5G terminal, thereby effectively assisting resource coordination between a 4G direct link and a 5G direct link.

FIG2 is one of the flow charts of the information processing method provided by the embodiment of the present invention. The method can be applied to the first terminal. As shown in FIG2, the method includes: Step 201, sending first indication information to the second terminal; Wherein, the first indication information is used to indicate the resource occupation information of the first direct link and/or the second direct link; The first terminal supports the first direct link and the second direct link, and the second terminal at least supports the second direct link.

Specifically, the first terminal is a terminal that supports a first direct link and a second direct link, wherein the first direct link and the second direct link respectively represent direct links under different communication standards, and the second direct link is a higher level than the communication standard corresponding to the first direct link. The advanced here means that according to the development of communication technology, the later the communication technology appears, the higher the level. 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 direct link to be supported, such as a 5G direct link, or a direct link under a new generation of communication standards. Here, the first direct link is mainly explained by taking the example of a 4G direct link and a 5G direct link.

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

By obtaining the occupancy of the resources of the above-mentioned 4G direct link and the resources of the 5G direct link, and sending it to the second terminal supporting the 5G direct link, the second terminal can determine the available resources of its own 5G direct link.

The information processing method provided by the embodiment of the present invention sends the resource occupation information of the first direct link and/or the second direct link to the second terminal supporting the second direct link, so that the second terminal can determine the time and frequency resources available for its second direct link, thereby reducing the probability of data packet transmission failure caused by the collision of the corresponding time and frequency resources of the first direct link and the second direct link, and improving the direct link data packet transmission success rate.

Optionally, the first indication information includes at least one of the following: Resource perception information; Indication information of time-frequency resources occupied by the first direct link; Indication information of time-frequency resources not occupied by the first direct link; Indication information of time-frequency resource conflicts between the first direct link and the second direct link.

Specifically, when the first terminal sends the occupation of the resources of the above-mentioned 4G direct link and the resources of the 5G direct link, it can specifically indicate the resource perception information directly perceived by the first terminal, or the resource information occupied by the 4G direct link determined by the first 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-mentioned resources usually refer to time-frequency resources in the network. Of course, according to the development of the network, it may also refer to resources corresponding to the time domain, frequency domain and air domain (space domain). The first indication information is determined based on the one or more indication information mentioned above and sent to the second terminal, so as to more flexibly indicate the time-frequency resources occupied or unoccupied by the terminal, so that the second terminal can determine the time-frequency resources available for its 5G direct link from the above indication information.

The resource perception information directly perceived by the first terminal is mainly information directly obtained without any calculation or processing.

The resource information occupied by the 4G direct link determined by the first terminal, or the resource information not occupied, 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 can be perceived by other terminals. The resource information not occupied by 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 conflict determined by the first terminal after sensing the occupancy of the 4G direct link and the occupancy of the 5G direct link and integrating the two information.

The information processing method provided by the embodiment of the present invention sends first indication information composed of one or more of resource perception information, time-frequency resources occupied by the first direct link, and related information that there is a conflict between the time-frequency resources occupied by the first direct link and the second direct link to a second terminal supporting a second direct link, so that the second terminal can determine the time-frequency resources available for its second direct link. More flexible indication of the resource occupied by the first direct link and the resource occupied by the second direct link is beneficial for the second terminal to determine the available resources of its second direct link in multiple ways, thereby reducing the probability of data packet transmission failure caused by the collision of the corresponding time and frequency resources of the first direct link and the second direct link, and improving the direct link data packet transmission success rate.

Optionally, the indication information of the time-frequency resources occupied by the first direct link, or the indication information of the time-frequency resources not occupied by the first direct link, is used to indicate at least one of the following information: Whether the time-frequency resources come from the first direct link; The time-frequency resources are the time-frequency resources occupied by the first direct link; The time-frequency resources are the time-frequency resources not occupied by the first direct link; The time-frequency resources occupied by the first direct link; The time-frequency resources not occupied by the first direct link.

Specifically, the indication information of the time-frequency resources occupied by the first direct link included in the first indication information, or the indication information of the time-frequency resources not occupied by the first direct link included in the first indication information, may further indicate one or more of the following: Indicates whether the occupied time-frequency resources or the unoccupied time-frequency resources come from the first direct link (4G direct link), and the indication information is represented by 1 bit, for example, when the value of 1 bit is 0, it indicates that the time-frequency resources come from the 4G direct link, and when the value of 1 bit is 1, it indicates that the time-frequency resources are not occupied by the 4G direct link, and vice versa; The indicated frequency resource information is the frequency resource information occupied by the 4G direct link or the 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 indicates that the frequency resource is the frequency resource information not occupied by the 4G direct link. When the value of 1 bit is 1, it indicates that the frequency resource is the frequency resource information occupied by the 4G direct link, and vice versa. Indicates the specific time-frequency resources occupied by the 4G direct link, or the specific time-frequency resources not occupied by the 4G direct link. The indication information is represented by N bits. The value of N can be set according to the maximum value of the corresponding resources of the 4G direct link, or according to actual needs.

Optionally, the first indication information includes indication information of a conflict between the time-frequency resources of the first direct link and the second direct link, which is used to indicate at least one of the following information: Whether there is a conflict between the time-frequency resources of the second direct link used by the second terminal and the time-frequency resources of the first direct link used by the third terminal supporting the first direct link; There is a potential resource conflict between the time-frequency resources of the first direct link and the second direct link; There is a detected resource conflict between the time-frequency resources of the first direct link and the second direct link; When there is a potential resource conflict between the first direct link and the second direct link, the location of the corresponding time-frequency resources; When a resource conflict is detected between the first direct link and the second direct link, the location of the corresponding time-frequency resource.

Specifically, the indication information of the conflict between the time-frequency resources of the first direct link and the second direct link included in the first indication information sent by the first terminal to the second terminal may further indicate one or more of the following: Indicates whether there is a resource conflict between the time-frequency resources of the 5G direct link used by the second terminal and the time-frequency resources of the 4G direct link used by the third terminal. The third terminal here mainly refers to other terminals that support 4G direct links, which are different from the first terminal and the second terminal; Indicates whether the conflict between the 4G direct link and the 5G direct link is a potential resource conflict or a detected resource conflict, wherein the potential resource conflict generally means that the time when the resource conflict is determined to exist is before the resource conflict occurs, that is, when the first terminal sends the first indication information, the time and frequency resources of the 5G direct link used by the second terminal and the third terminal are different. The detected resource conflict usually means that the detected time is after the resource conflict occurs, that is, the time when the first terminal sends the first indication information, and after the time and frequency resources of the 5G direct link used by the second terminal and the time and frequency resources of the 4G direct link used by the third terminal conflict. The indication information is usually represented by 1 bit, for example, when the value of 1 bit is 0, it means that the resource conflict is a potential resource conflict, and when the value of 1 bit is 1, it means that the resource conflict is a detected resource conflict, and vice versa; When indicating that there is a potential resource conflict between the 4G direct link and the 5G direct link, the location of the corresponding time-frequency resource, or when indicating that there is a detected resource conflict between the 4G direct link and the 5G direct link, the location of the corresponding time-frequency resource; this seventh indication information is associated with the sixth indication information. When the sixth indication information indicates that there is a potential resource conflict between the 4G direct link and the 5G direct link, the seventh indication information corresponds to the location of the time-frequency resource corresponding to the potential resource conflict. When the sixth indication information indicates that there is a detected resource conflict between the 4G direct link and the 5G direct link, the seventh indication information corresponds to the location of the time-frequency resource corresponding to the detected resource conflict.

Optionally, the resource perception information is used to indicate at least one of the following information: Perception information of the time-frequency resources occupied by the first direct link and/or perception information of the time-frequency resources occupied by the second direct link; In the case where there is a conflict between the time-frequency resources of the first direct link and the second direct link, the resource perception information is the perception information of the time-frequency resources of the first direct link and/or the perception information of the time-frequency resources of the second direct link; The perception information of the time-frequency resources of the first direct link is periodic or aperiodic; The perception information of the time-frequency resources of the second direct link is periodic or aperiodic; The third terminal supporting the first direct link and the fourth terminal supporting the second direct link belong to different resource pools, or belong to the same resource pool.

Specifically, the resource perception information included in the first indication information sent by the first terminal to the second terminal may further indicate one or more of the following: Indicating that the resource perception information includes resource perception information of a 4G direct link, resource perception information of a 5G direct link, or resource perception information of a 4G direct link and resource perception information of a 5G direct link; Indicating that there is a resource conflict between the 4G direct link and the 5G direct link, the resource perception information is the perception information of the time-frequency resources of the 4G direct link, or the perception information of the time-frequency resources of the 5G direct link, or the perception information of the time-frequency resources of both the 4G direct link and the 5G direct link. The indication information is represented by 2 bits, for example, the 2 bits correspond to When the value of is 1, it indicates that the resource perception information is the perception information of the time-frequency resources of the 4G direct link. When the corresponding value of the two bits is 2, it indicates that the resource perception information is the perception information of the time-frequency resources of the 5G direct link. When the corresponding value of the two bits is 3, it indicates that the resource perception information contains both the perception information of the time-frequency resources of the 4G direct link and the perception information of the time-frequency resources of the 5G direct link. Of course, it can also be based on the case where the high bit of the two bits is 1 and the low bit is 0, indicating that the resource perception information is the perception information of the time-frequency resources of the 4G direct link, and the case where the high bit of the two bits is 0 and the low bit is 1, indicating that the resource perception information is the perception information of the time-frequency resources of the 5G direct link.

Indicates whether the perception information of the time-frequency resources of the 4G direct link is periodic or non-periodic. In the case of periodicity, the value of the period can be set to 1 second, which is equivalent to full perception, that is, the occupancy of the time-frequency resources of the 4G direct link is perceived every second. The value of the period is set to a duration less than 24 hours, such as 5 hours, 30 minutes, 45 seconds, which corresponds to periodic partial perception; and for non-periodic situations, the corresponding occupancy of the time-frequency resources of the 4G direct link can be continuously perceived in a certain period of time; Indicates whether the perception information of the time-frequency resources of the 5G direct link is periodic or non-periodic. The specific indication method is the same as the periodic or non-periodic implementation of the perception information of the time-frequency resources for indicating the 4G direct link, and will not be repeated here; Indicating that the third terminal and the fourth terminal belong to different resource pools, or belong to the same resource pool; The third terminal is a terminal different from the first terminal and the second terminal, and the third terminal only supports the 4G direct link, and the fourth terminal includes the first terminal and the second terminal and supports the 5G direct link.

Optionally, the first indication information further includes resource pool indication information, and the resource pool indication information is used to indicate the resource pool available for the second direct link of the second terminal.

Specifically, the first indication information sent by the first terminal to the second terminal also includes resource pool indication information, and the resource pool indication information is used to indicate an available resource pool, which can be used as an available time and frequency resource for the 5G direct link of the second terminal in its entirety or in part.

Optionally, the method for determining the resource pool indication information includes: Determining the resource pool indication information 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 perception information.

Specifically, the first indication information determined by the first terminal also includes resource pool indication information, which is determined by the first terminal through resource perception information directly obtained, and whether the third terminal supporting the first direct link and the fourth terminal supporting the second direct link belong to the same resource pool. The resource perception information may include resource perception information of the 4G direct link, resource perception information of the 5G direct link, and whether the third terminal and the fourth terminal belong to the same resource pool.

Optionally, the resource pool indication information 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 perception information, including: If they belong to different resource pools, the resource pool indication information is determined based on the perception information of the time-frequency resources occupied by the second direct link indicated by the resource perception information and the resource pool to which the fourth terminal belongs; If they belong to the same resource pool, the resource pool indication information is determined based on the perception information of the time-frequency resources occupied by the first direct link indicated by the resource perception information and/or the perception information of the time-frequency resources occupied by the second direct link.

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 perception information of the time-frequency resources occupied by the 5G direct link indicated by the resource perception 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, i.e., the resource pool indication information, is determined and 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 resource pool indication information included in the first indication information based on at least one of the resource perception information of the 4G direct link and the resource perception information of the 5G direct link.

The specific method for determining the resource pool indication information is as follows: 1. When the third terminal and the fourth terminal belong to different resource pools: Determine that the resource pool to which the fourth terminal belongs is resource pool B; According to the perception information of the time-frequency resources occupied by the 5G direct link, determine the first time-frequency resources, that is, the time-frequency resources occupied by the 5G direct link; Determine all or part of the time-frequency resources in the resource pool B except the first time-frequency resource as the time-frequency resources available for the second direct link of the second terminal, that is, the resource pool of time-frequency resources available for the 5G direct link of the second terminal. Then, the resource pool indication information is a set of indication information corresponding to all or part of the time-frequency resources in the resource pool B except the first time-frequency resource.

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 as the basic resource pool.

When only the resource perception information of the 4G direct link is perceived, the time and frequency resources occupied by the 4G direct link are determined, and further, all or part of the resources in the above-mentioned basic resource pool except the time and frequency resources occupied by the 4G direct link can be determined as the resource pool of time and frequency resources available for the 5G direct link of the second terminal. Then, the above-mentioned resource pool indication information is a collection of indication information corresponding to all or part of the resources in the basic resource pool except the time and frequency resources occupied by the 4G direct link.

When the resource perception information of the 4G direct link and the resource perception information of the 5G direct link are perceived, the time-frequency resources occupied by the 4G direct link and the time-frequency resources occupied by the 5G direct link can be determined respectively, and the sum of the time-frequency resources occupied by the 4G direct link and the time-frequency resources occupied by the 5G direct link can be determined as the joint perception resource; further, all or part of the resources in the above-mentioned basic resource pool except the joint perception resource are determined as the resource pool of the time-frequency resources available for the 5G direct link of the second terminal. Then, the above-mentioned 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 perception resource.

Optionally, the sending of the first indication information to the second terminal for determining the time-frequency resources available for the second direct link of the second terminal includes: Determining whether the first terminal and the second terminal are within the coverage range of the same base station; If they are within the coverage range of the same base station, the first terminal sends the first indication information to the second terminal through the same base station; If they are not within the coverage range of the same base station, the first terminal sends the first indication information to the second terminal through the second direct link.

Specifically, the first terminal sends the first indication information to the second terminal, which can be sent directly through the 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, the first terminal forwards the first indication information to the second terminal through the base station to which the two are 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 4G modules and 5G modules. The 4G module is mainly used to support 4G direct links, or to sense the time and frequency resources occupied by 4G direct links; the 5G module is mainly used to support 5G direct links, or to sense the time and frequency resources occupied by 5G direct links.

The second terminal includes at least a 5G module; the third terminal includes a 4G module, and the fourth terminal includes a 5G module, corresponding to the first terminal, the second terminal and other terminals including 5G modules.

When the first terminal and the second terminal are within the coverage of the same base station, the first terminal senses the time-frequency resource information occupied by the 4G direct link through the 4G module, and sends other indication information included in the first indication information to the same base station, which is then forwarded 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 5G module of the first terminal, and the 5G module of the first terminal also senses the time-frequency resource information occupied by the 5G direct link. Finally, the time-frequency resource information occupied by the 4G direct link and the time-frequency resource information occupied by the 5G direct link, as well as other indication information included in the first indication information, are sent to the 5G module of the second terminal through the 5G module of the first terminal.

In addition, there is a situation 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 sends the time-frequency resource information occupied by the 5G direct link perceived by the 4G module and the 5G module respectively, as well as other indication information included in the first indication information, to the 5G module of the second terminal.

Optionally, the method for obtaining the resource perception information includes: Based on the resource perception window, obtaining a first signal sent by the third terminal; the first signal is used to determine the time-frequency resources occupied by the first direct link; and/or, based on the resource perception window, obtaining a second signal sent by the second terminal; the second signal is used to determine the time-frequency resources occupied by the second direct link; The resource perception window is a time window for the first terminal to perform resource perception.

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

Similarly, the 5G module can obtain a 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 direct link control information SCI.

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

In the present invention, the acquisition of resource perception information mainly includes the perception information of the time-frequency resources occupied by the 4G direct link, which is determined by obtaining the SA signal sent by the third terminal to determine the time-frequency resources occupied by the 4G direct link.

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

The information processing method provided by the embodiment of the present invention sends resource perception information, the time and frequency resources occupied by the first direct link, and the relevant information that the time and frequency resources occupied by the first direct link and the second direct link conflict to the second terminal supporting the second direct link, so that the second terminal can determine the time and frequency resources available for its second direct link. This reduces the probability of data packet transmission failure caused by the collision of the corresponding time and frequency resources of the first direct link and the second direct link, and improves the direct link data packet transmission success rate.

FIG3 is a second flow chart of the information processing method provided by the embodiment of the present invention. The method can be applied to the second terminal. As shown in FIG3, the method includes: Step 301, based on the received first indication information, determine the time and frequency resources available for the second direct link of the second terminal; The first indication information is sent by the first terminal and is used to indicate the resource occupancy information of the first direct link and/or the second direct link; The first terminal supports the first direct link and the second direct link, and the second terminal supports at least the second direct link.

Specifically, the first terminal is a terminal that supports a first direct link and a second direct link, wherein the first direct link and the second direct link respectively represent direct links under different communication standards, and the second direct link is a higher level than the communication standard corresponding to the first direct link. The advanced here means that according to the development of communication technology, the later the communication technology appears, the higher the level. 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 direct link to be supported, such as a 5G direct link, or a direct link under a new generation of communication standards. Here, the first direct link is mainly explained by taking the example of a 4G direct link and a 5G direct link.

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

The first terminal obtains the occupancy of the resources of the above-mentioned 4G direct link and the resources of the 5G direct link, and sends it to the second terminal supporting the 5G direct link, so that the second terminal can determine the available resources of its own 5G direct link.

The information processing method provided by the embodiment of the present invention sends the resource occupation information of the first direct link and/or the second direct link to the second terminal supporting the second direct link, so that the second terminal can determine the time and frequency resources available for its second direct link, thereby reducing the probability of data packet transmission failure caused by the collision of the corresponding time and frequency resources of the first direct link and the second direct link, and improving the direct link data packet transmission success rate.

Optionally, the first indication information includes at least one of the following: Resource perception information; Indication information of time-frequency resources occupied by the first direct link; Indication information of time-frequency resources not occupied by the first direct link; Indication information of time-frequency resource conflicts between the first direct link and the second direct link.

Specifically, when the first terminal sends the occupation of the resources of the above-mentioned 4G direct link and the resources of the 5G direct link, it can specifically indicate the resource perception information directly perceived by the first terminal, or the resource information occupied by the 4G direct link determined by the first 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-mentioned resources usually refer to time-frequency resources in the network. Of course, according to the development of the network, it may also refer to resources corresponding to the time domain, frequency domain and air domain (space domain). The first indication information is determined based on the one or more indication information mentioned above and sent to the second terminal, so as to more flexibly indicate the time-frequency resources occupied or unoccupied by the terminal, so that the second terminal can determine the time-frequency resources available for its 5G direct link from the above indication information.

The resource perception information directly perceived by the first terminal is mainly information directly obtained without any calculation or processing.

The resource information occupied by the 4G direct link determined by the first terminal, or the resource information not occupied, 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 can be perceived by other terminals. The resource information not occupied by 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 conflict determined by the first terminal after sensing the occupancy of the 4G direct link and the occupancy of the 5G direct link and integrating the two information.

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

The information processing method provided by the embodiment of the present invention sends first indication information composed of one or more of resource perception information, time-frequency resources occupied by the first direct link, and related information that there is a conflict between the time-frequency resources occupied by the first direct link and the second direct link to a second terminal supporting a second direct link, so that the second terminal can determine the time-frequency resources available for its second direct link. More flexible indication of the resource occupied by the first direct link and the resource occupied by the second direct link is beneficial for the second terminal to determine the available resources of its second direct link in multiple ways, thereby reducing the probability of data packet transmission failure caused by the collision of the corresponding time and frequency resources of the first direct link and the second direct link, and improving the direct link data packet transmission success rate.

Optionally, the determining the time-frequency resources available for the second direct link of the second terminal based on the received first indication information includes: Based on the resource perception information included in the first indication information, determining whether the third terminal supporting the first direct link and the fourth terminal supporting the second direct link indicated by the resource perception information belong to different resource pools or the same resource pool; If they belong to different resource pools, then based on the perception information of the time-frequency resources occupied by the second direct link indicated by the resource perception information and the resource pool to which the fourth terminal belongs, determining the time-frequency resources available for the second direct link of the second terminal; If they belong to the same resource pool, based on the perception information of the time-frequency resources occupied by the first direct link and/or the perception information of the time-frequency resources occupied by the second direct link indicated by the resource perception information, the time-frequency resources available for the second direct link of the second terminal are determined.

Specifically, the second terminal receives the first indication information sent by the first terminal, determines whether the first indication information includes resource perception information, and if it includes resource perception information, further determines whether the third terminal and the fourth terminal belong to the same resource pool based on the indication of the resource perception information; that is, determines 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 the resources in the resource pool belonging to the fourth terminal. Then, according to the perception information of the time-frequency resources occupied by the 5G direct link indicated by the resource perception information and the resource pool to which the fourth terminal belongs, the resource pool of the 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 resource pool of the time-frequency resources available for the 5G direct link of the second terminal is determined based on at least one of the resource perception information of the 4G direct link and the resource perception information of the 5G direct link indicated by the first indication information; that is, the resource pool of the time-frequency resources available for the 5G direct link of the second terminal is determined through the perception information of the time-frequency resources occupied by the first direct link and the perception information of the time-frequency resources occupied by the second direct link.

Optionally, the determining the time-frequency resources available for the second direct link of the second terminal based on the perception information of the time-frequency resources occupied by the second direct link indicated by the resource perception information and the resource pool to which the fourth terminal belongs includes: Determining the first time-frequency resources based on the perception information of the time-frequency resources occupied by the second direct link; Determining all or part of the time-frequency resources in the resource pool to which the fourth terminal belongs except the first time-frequency resources as the time-frequency resources available for the second 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 that the resource pool to which the fourth terminal belongs is resource pool B; Determine the first time-frequency resources, i.e., the time-frequency resources occupied by the 5G direct link, based on the perception information of the time-frequency resources occupied by the 5G direct link; Determine all or part of the time-frequency resources in resource pool B except the first time-frequency resources as the time-frequency resources available for the second direct link of the second terminal, i.e., the resource pool of the time-frequency resources available for the 5G direct link of the second terminal.

Optionally, the sensing information of 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 determines the time-frequency resources available for the second direct link of the second terminal, including: If the resource sensing information only indicates the sensing information of the time-frequency resources occupied by the first direct link, then all or part of the time-frequency resources in the basic resource pool except the time-frequency resources occupied by the first direct link are determined as the time-frequency resources available for the second direct link of the second terminal; If the resource perception information indicates the perception information of the time-frequency resources occupied by the first direct link and the perception information of the time-frequency resources occupied by the second direct link, all or part of the time-frequency resources in the basic resource pool except the joint perception resources are determined as the time-frequency resources available for the second direct link of the second terminal; Wherein, the basic resource pool is the same resource pool to which the third terminal and the fourth terminal belong; the joint perception resources are the time-frequency resources occupied by the first direct link and the time-frequency resources occupied by the second direct link.

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 determines the time-frequency resources available for the second direct link of the second terminal based on the perception information of the time-frequency resources occupied by the first direct link and/or the perception information of the time-frequency resources occupied by the second direct link. 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. When it is determined that only the resource perception information indicating the 4G direct link is included, the time and frequency resources occupied by the 4G direct link are determined, and further, all or part of the resources in the above basic resource pool except the time and frequency resources occupied by the 4G direct link can be determined as the resource pool of time and frequency resources available for the 5G direct link of the second terminal.

When it is determined that the indication includes both resource perception information of the 4G direct link and resource perception information of the 5G direct link, the time-frequency resources occupied by the 4G direct link and the time-frequency resources occupied by the 5G direct link are determined as joint perception resources; and all or part of the resources in the above-mentioned basic resource pool except the joint perception resources are further determined as the resource pool of time-frequency resources available for the 5G direct link of the second terminal.

Optionally, the determining the time-frequency resources available for the second direct link of the second terminal based on the received first indication information further includes: If the first indication information includes resource pool indication information, then determining the time-frequency resources available for the second direct link of the second terminal according to the resource pool indication information.

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 are the available time-frequency resources according to the resource pool indication information, and select part or all of them as the resource pool of the available time-frequency resources of the 5G direct link of the second terminal. 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 multiple indication information, or directly through one of the indication information.

The information processing method provided by the embodiment of the present invention sends resource perception information, the time and frequency resources occupied by the first direct link, and the relevant information that the time and frequency resources occupied by the first direct link and the second direct link conflict to the second terminal supporting the second direct link, so that the second terminal can determine the time and frequency resources available for its second direct link. This reduces the probability of data packet transmission failure caused by the collision of the corresponding time and frequency resources of the first direct link and the second direct link, and improves the direct link data packet transmission success rate.

The information processing method provided by the present invention is further described below with several specific examples. 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 to the second terminal (terminal A) via a direct link or via a commonly connected base station.

Terminal A determines its available 5G direct link time and frequency resource candidate set according to the first indication information, wherein the first indication information includes at least one of 4G direct link resource indication information, time and frequency resource information occupied by 4G direct link, time and frequency resource information not occupied by 4G direct link, 4G and 5G direct link resource conflict indication information, priority related information, resource perception information, Semi-Persistent Scheduling (SPS) information, Channel Busy Ratio (CBR) information, and 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 supports both 4G direct link and 5G direct link.

Specifically, when the 4G direct link and the 5G direct link share frequency resources or are located in the same resource pool, in order to avoid resource collision between the 4G direct link and the 5G direct link, the resources used by the 4G direct link need to be sent to the 5G terminal so that the 5G terminal can exclude the frequency resources occupied by these 4G direct links when determining its available 5G direct link frequency resource candidate set.

Terminal A and Terminal B are both 5G terminals, and both 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 pass-through link; Terminal A may or may not support a 4G pass-through link. Terminal B is a terminal that has both a 4G module and a 5G module, and supports both a 4G pass-through link and a 5G pass-through link.

Terminal B obtains the information of the time and frequency resources occupied by the 4G direct link, the time and frequency resources not occupied by the 4G direct link, and the information indicating the conflict between the 4G and 5G direct link resources through its 4G direct link module, and then forwards it to its 5G direct link module within Terminal B. Then, Terminal B sends the obtained information about the 4G direct link resources to Terminal A through the 5G direct link module.

FIG4 is one of the schematic diagrams of the implementation process of the first terminal sending the first indication information provided by the embodiment of the present invention. As shown in FIG4 , 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 consisting 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 a second schematic diagram of the implementation process of the first terminal sending the first indication information provided by the embodiment of the present invention. As shown in Figure 5, terminal A and terminal B are not within the coverage range of the same base station, and terminal A only includes a 5G module. Since terminal A does not have a 4G module, it cannot perceive the time-frequency resource information occupied by the 4G direct link. Therefore, terminal B uses the 5G direct link to send the first indication information consisting of these 4G direct link resource-related information and other indication information to terminal A, so that terminal A obtains the first indication information.

Figure 6 is a third schematic diagram of the implementation process of the first terminal sending the first indication information provided by the embodiment of the present invention. As shown in Figure 6, terminal A and terminal B are not within the coverage range of the same base station, and terminal A includes a 4G module and a 5G module. Although terminal A has a 4G module, due to the hidden node problem, terminal A cannot perceive the time-frequency resource information occupied by the 4G direct link. Therefore, terminal B uses the 5G direct link to send the first indication information consisting of these 4G direct link resource-related information and other indication information to terminal A, so that terminal A obtains the first indication information.

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

Terminal A determines its available 5G direct link time and frequency resource candidate set according to the first indication information, and the first indication information includes at least one of 4G direct link resource indication information and time and frequency resource information occupied by 4G direct link. 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 indication information indicating whether it belongs to 4G direct link resources, and 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 is represented by 1 bit; The first indication information includes indication information indicating occupied or unoccupied 4G direct link resources, and the indication information is used to indicate whether the time-frequency resource information indicated in the first indication 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; The first indication information includes the time-frequency resource information occupied by the 4G direct link, indicating the specific time-frequency resource occupied by the 4G direct link.

A subchannel is a frequency domain unit for direct link resource configuration. A subchannel consists of one or more continuous physical resource blocks (PRBs) in the frequency domain. 4G terminals indicate the direct link time and frequency resources they occupy by sending scheduling allocation information SA, and 5G terminals indicate the direct link time and frequency resources they occupy by sending direct link control information SCI.

FIG7 is a schematic diagram of the first indication information provided by an embodiment of the present invention including the time-frequency resource information occupied by the 4G direct link. As shown in FIG7 , the 4G terminal sends SA on the time slot 3 of the sub-channel 3, and the SA indicates that the resources on the time slot 7 of the 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 5 and obtains the 4G direct link resource occupancy information. Terminal B then sends the 4G resource occupancy information to terminal A in time slot 5. When terminal A selects time-frequency resources in time slot 6, it selects sub-channel 1 to avoid sub-channel 2 occupied by the 4G terminal, thereby avoiding 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 4G direct link resource occupancy information through other means and then indicate it to Terminal A. For example, Terminal B receives indication information from a base station or other terminals to obtain 4G direct link resource occupancy information.

When the first indication information includes information indicating whether the time-frequency resources come 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 is 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, the resources on the 7th time slot of the 2nd subchannel shown in Figure 7.

By adopting this method of sending the first indication information, terminal A can obtain the resource occupancy of the 4G direct link, so that terminal A can determine its available 5G direct link time and frequency resource candidate set according to the first indication information, so that 4G direct link communication and 5G direct link communication can coexist, thereby reducing the probability of data packet transmission failure caused by the collision of 4G and 5G direct link resources and improving the direct link data packet transmission success rate. Since the specific time and frequency resource information is indicated, it may bring higher signaling consumption.

Example 3: The first indication information is information about the frequency resources that are not occupied by the 4G direct link.

Terminal A determines its available 5G direct link time and frequency resource candidate set according to the first indication information, and the first indication information includes at least one of 4G direct link resource indication information and time and frequency resource information not occupied by the 4G direct link. 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 4G terminal indicates the direct link time-frequency resources it occupies by sending SA, and the 5G terminal indicates the direct link time-frequency resources it occupies by sending SCI.

FIG8 is a schematic diagram of the first indication information provided by an embodiment of the present invention including the time-frequency resource information not occupied by the 4G direct link. As shown in FIG8 , the 4G terminal sends SA on the time slot 3 of the sub-channel 3, and the SA indicates that the resources on the time slot 7 of the 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 5 and obtains the 4G direct link resource occupancy information. Terminal B then sends the 4G resource occupancy information to terminal A in time slot 5. When terminal A selects time-frequency resources in time slot 6, it selects sub-channel 1 to avoid sub-channel 2 occupied by the 4G terminal, thereby avoiding 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 4G direct link resource occupancy information through other means and then indicate it to Terminal A. For example, Terminal B receives indication information from a base station or other terminals to obtain 4G direct link resource occupancy information.

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

By adopting this method of sending the first indication information, terminal A can obtain the situation that the resources of the 4G direct link are not occupied, so that terminal A can determine its available 5G direct link time and frequency resource candidate set according to the first indication information, so that 4G direct link communication and 5G direct link communication can coexist, thereby reducing the probability of data packet transmission failure caused by the collision of 4G and 5G direct link resources and improving the direct link data packet transmission success rate. Since the specific time and frequency resource information is indicated, it may bring higher signaling consumption.

Example 4: The first indication information is the indication information of potential resource conflict between the 4G and 5G direct links.

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

Figure 9 is one of the schematic diagrams of the first indication information provided by an embodiment of the present invention, including the indication information of potential resource conflict between 4G and 5G direct links. As shown in Figure 9, the 5G module of terminal A sends SCI on time slot 2 of sub-channel 1, and the 4G terminal sends SA on time slot 3 of sub-channel 3. Both the SCI and SA indicate that the resources on time slot 6 of sub-channel 2 will be used by terminal A and the 4G terminal to send data respectively, thus causing a resource conflict. Terminal B monitors the SCI sent by Terminal A and the SA sent by the 4G terminal in time slot 5, and learns of the resource conflict information. Terminal B then sends the resource conflict information to Terminal A in time slot 5, and Terminal A changes its transmission resources to avoid the resource conflict. 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 indication information sent directly by other terminals or sent by other terminals through base stations, thereby obtaining the 4G and 5G direct link resource conflict indication information.

By adopting this method of sending the first indication information, terminal A can obtain the potential conflict of 4G and 5G direct link resources, so that terminal A can determine its available 5G direct link time and frequency resource candidate set or retransmit data according to the first indication information, so that 4G direct link communication and 5G direct link communication can coexist, thereby reducing the probability of data packet transmission failure caused by the collision of 4G and 5G direct link resources and improving the success rate of direct link data packet transmission. In addition, since only whether there is a resource conflict is indicated, the signaling consumption is small, but since no specific time and frequency resource information is indicated, the amount of information that can be brought is small.

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

Terminal A determines its available 5G direct link 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.

A 4G terminal indicates the direct link time-frequency resources it occupies by sending SA, and a 5G terminal indicates the direct link time-frequency resources it occupies by sending SCI.

FIG10 is a second schematic diagram of the first indication information provided by an embodiment of the present invention including the indication information of potential resource conflict between 4G and 5G direct links. As shown in FIG10 , terminal B monitors the SCI sent by the 5G module of terminal A and the SA sent by the 4G terminal at time slot 7, and obtains the resource conflict information. In this way, the 5G module of terminal B sends the resource conflict information to terminal A at time slot 7, and the 5G module and 4G module of terminal A will switch transmission resources and then retransmit 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 a base station or other terminals, thereby obtaining the 4G and 5G direct link resource conflict indication information.

As shown in Figure 11, the 4G terminal sends SA on time slot 3 of sub-channel 3, and the SA indicates that the resources on time slot 6 of sub-channel 2 will be used by the 4G terminal to send data. In this way, terminal B perceives the SA sent by the 4G terminal in time slot 5 and obtains the resource occupancy information. In this way, terminal B sends the resource perception information to terminal A in time slot 5, and terminal A will change the transmission resources to avoid the occurrence of resource conflicts.

As shown in Figure 12, the 5G terminal sends SCI on time slot 2 of sub-channel 1, and the 4G terminal sends SA on time slot 3 of sub-channel 3. The SCI and SA respectively indicate that the resources on time slot 6 of sub-channel 1 and time slot 6 of sub-channel 2 will be used by the 5G terminal and the 4G terminal to send data, respectively. In this way, terminal B perceives the SCI and SA sent by the 5G terminal and the 4G terminal respectively in time slot 5, and obtains the resource occupancy information. In this way, terminal B sends these resource perception information to terminal A in time slot 5, and terminal A will change the transmission resources to avoid the occurrence of resource conflicts.
