Description

Technical Field

[0001] The present application relates to the field of communications, and in particular to a resource configuration method and device. Background Art

[0002] Currently, a terminal device can sense the resource occupancy in a resource pool to determine candidate resources for sidelink (SL) communication of the terminal device. Specifically, the terminal device can determine the candidate resources based on the power measurement results of each resource in the resource pool. For example, if the reference signal receiving power (RSRP) measured by the terminal device on a certain resource is greater than the power threshold, the terminal device needs to exclude the current resource, the retransmission reserved resource indicated in the sidelink control information (SCI), and the periodic reserved resource.

[0003] However, the above-mentioned resource perception is all performed by the terminal device itself. There may be situations where the terminal device fails to perceive that certain resources have been occupied by another terminal device due to environmental factors such as obstruction. In this case, the terminal device may occupy the occupied resources, resulting in a resource conflict, that is, the terminal device and the other terminal device occupy the same resource at the same time. In this way, the terminal device's peer device may receive the signals sent by the terminal device and the other terminal device at the same time on the same resource, thereby causing mutual interference, such as the near-far effect. For example, if the distance between the peer device and the other terminal device and the distance between the peer device and the terminal device are significantly different, the peer device may not receive signals with a longer transmission distance, resulting in low communication reliability.

[0004] Furthermore, an assisted terminal sensing solution has been introduced. This solution allows a terminal device to combine its own sensing results with those of an assisted terminal to determine candidate resources, reducing the probability of resource conflicts and interference levels. However, this assisted terminal sensing solution remains at the conceptual level, with no detailed technical solution yet. Summary of the Invention

[0005] The embodiments of the present application provide a resource configuration method and apparatus, which are used to enable an auxiliary terminal to assist higher priority side transmission services as much as possible and reduce the interference of the auxiliary terminal to normal side transmission.

[0006] To achieve the above objectives, this application adopts the following technical solutions:

[0007] In a first aspect, a resource configuration method is provided. The resource configuration method includes: a first terminal obtains first information and second information. The first information includes a first service priority and / or a first auxiliary priority; wherein the first service priority is the physical layer priority of the first terminal, and the first auxiliary priority is the priority of the first terminal to assist the third terminal in selecting side transmission resources. The second information includes a second service priority and / or a second auxiliary priority; wherein the second service priority is the physical layer priority of the second terminal; and the second auxiliary information is the priority of the second terminal to assist the fourth terminal in selecting side transmission resources. The first terminal determines the candidate resources of the first terminal based on the first information and the second information. wherein the candidate resources of the first terminal are used for the side transmission of the first terminal, and / or for the side transmission of the first terminal to assist the third terminal.

[0008] Based on the resource configuration method provided in the first aspect, the first terminal determines, based on the first service priority and / or the first auxiliary priority, and the second service priority and / or the second auxiliary priority, candidate resources for sideline transmission by the first terminal, and / or candidate resources for sideline transmission by the first terminal in assistance of a third terminal. Thus, when the first terminal assists a third terminal with a higher-priority sideline transmission, the first terminal can obtain more candidate resources when transmitting assistant information (ASI); or, when the second terminal assists a fourth terminal with a higher-priority sideline transmission, the second terminal can obtain more candidate resources when transmitting assistant information; and interference caused by the assisting terminal to normal sideline transmission is reduced.

[0009] In one possible design, the first terminal determines candidate resources for the first terminal based on the first and second information, including: excluding resources corresponding to the second service priority or the second auxiliary priority from the candidate resources of the first terminal based on the first and second information; and / or preempting resources corresponding to the second service priority or the second auxiliary priority based on the first and second information. That is, the first terminal determines candidate resources for the first terminal based on the first and second information, including the following two aspects: first, excluding resources corresponding to the second service priority or the second auxiliary priority from the candidate resources of the first terminal if the following first, second, or third conditions are met. Second, preempting resources corresponding to the second service priority or the second auxiliary priority if the following fourth, fifth, or sixth conditions are met, i.e., adding resources corresponding to the second service priority or the second auxiliary priority perceived by the first terminal to the candidate resources of the first terminal. By excluding or preempting, the resources corresponding to the second terminal can be excluded from the candidate resources of the first terminal when the physical layer priority or auxiliary resource selection priority of the second terminal is higher; and the resources corresponding to the second terminal can be occupied by the first terminal when the physical layer priority or auxiliary resource selection priority of the second terminal is lower. This enables the first terminal to assist the third terminal in side transmission, and the first terminal can obtain more candidate resources when sending auxiliary information, or when the second terminal assists the fourth terminal in side transmission, the second terminal can obtain more candidate resources by sending auxiliary information, so that resources can be effectively utilized and interference with normal side transmission can be reduced.

[0010] Optionally, the first terminal further obtains one or more of a first reference signal received power, a first power threshold, a first priority threshold, and a second priority threshold. The first priority threshold and the second priority threshold can both be indicated by upper-layer parameters of the first terminal or configured by radio resource control (RRC) signaling. The first priority threshold is used to assist in determining whether the resources corresponding to the second auxiliary priority meet the exclusion condition. The second priority threshold is used to assist in determining whether the conditions for preempting the resources corresponding to the second service priority are met. The first priority threshold can be equal to the second priority threshold. That is, the first priority threshold and the second priority threshold can be indicated by the same upper-layer parameter, or configured by the same RRC signaling. It should be noted that the first reference signal received power is measured by the first terminal. The first power threshold is associated with the priority of the service, that is, the first power threshold is a threshold in a threshold list determined by the upper-layer parameters of the first terminal, which corresponds to two priorities, one priority determined by the upper-layer parameters of the first terminal, and the other priority obtained by SCI demodulation. In this way, the first reference signal received power obtained by the first terminal can be compared with the first power threshold. By comparing these two parameters, it can also be determined whether the first terminal needs to exclude or seize the resources reserved by the second terminal, so that when the first terminal assists the third terminal in side transmission, the first terminal has more candidate resources for sending auxiliary information.

[0011] It should be noted that when an auxiliary terminal assists a normal terminal in sideline transmission, resource sensing by the auxiliary terminal can be divided into three scenarios, as follows:

[0012] Scenario 1: A first terminal functions as a normal terminal in sideline transmission with a fifth terminal, and a second terminal functions as an auxiliary terminal to assist a fourth terminal in sideline transmission with a sixth terminal. The first information acquired by the first terminal may include a first service priority. The second information acquired by the first terminal may include a second service priority and a second auxiliary priority.

[0013] Scenario 2: The first terminal acts as an auxiliary terminal to assist the third terminal in sideline transmission with the fifth terminal, while the second terminal acts as a normal terminal in sideline transmission with the sixth terminal. The first information acquired by the first terminal may include the first service priority and the first auxiliary priority. The second information acquired by the first terminal may include the second service priority.

[0014] Scenario 3: The first terminal acts as an auxiliary terminal to assist the third terminal and the fifth terminal in sideline transmission, and the second terminal acts as an auxiliary terminal to assist the fourth terminal and the sixth terminal in sideline transmission. The first information acquired by the first terminal may include a first service priority and a first auxiliary priority. The second information acquired by the first terminal may include a second service priority and a second auxiliary priority.

[0015] For scenario 1, the first terminal excludes resources corresponding to the second service priority or the second auxiliary priority from candidate resources of the first terminal based on the first information and the second information, which may include: if the first condition is met, the first terminal excludes resources corresponding to the second service priority or the second auxiliary priority from candidate resources of the first terminal. The first condition may include one or more of the following: the second service priority is higher than the first service priority; or the second service priority is equal to the first service priority and the second auxiliary priority is higher than the first priority threshold; or the first reference signal received power is greater than the first power threshold; or the first reference signal received power is equal to the first power threshold and the second auxiliary priority is higher than the first priority threshold; or the second service priority is higher than the first service priority and the second auxiliary priority is higher than the first priority threshold; or the first reference signal received power is greater than the first power threshold and the second auxiliary priority is higher than the first priority threshold; or the lowest priority of the second service priority and the second auxiliary priority is higher than the first service priority; or the first reference signal received power is greater than the first power threshold and the second auxiliary priority is higher than the first priority threshold; or the highest priority of the second service priority and the second auxiliary priority is higher than the first service priority; or the second auxiliary priority is higher than the first service priority.

[0016] In the first condition described above, during the resource perception and resource selection process, the first terminal may exclude resources used for sideline transmission services corresponding to a higher-level second service priority, or exclude resources used for auxiliary sideline transmission services corresponding to a higher-level second auxiliary priority. The first terminal may also avoid excluding resources used for sideline transmission services corresponding to a lower-level second service priority, or avoid excluding resources used for auxiliary sideline transmission services corresponding to a lower-level second auxiliary priority. This allows the second terminal, acting as an auxiliary terminal, to use the corresponding resources to assist the fourth terminal's sideline transmission, or prevents the second terminal from using the corresponding resources to assist the fourth terminal's sideline transmission.

[0017] For scenario 2, the first terminal excludes resources corresponding to the second service priority or the second auxiliary priority from the candidate resources of the first terminal based on the first information and the second information, and may also include: if the second condition is met, the first terminal excludes resources corresponding to the second service priority from the candidate resources of the first terminal. The second condition may include one or more of the following: the second service priority is higher than the first service priority; or the second service priority is equal to the first service priority and the first auxiliary priority is lower than the first priority threshold; or the first reference signal received power is greater than the first power threshold; or the first reference signal received power is equal to the first power threshold and the first auxiliary priority is lower than the first priority threshold; or the second service priority is higher than the first service priority and the first auxiliary priority is lower than the first priority threshold; or the first reference signal received power is greater than the first power threshold and the first auxiliary priority is lower than the first priority threshold; or the second service priority is higher than the highest priority of the first service priority and the first auxiliary priority; or the first reference signal received power is greater than the first power threshold and the second service priority is higher than the first auxiliary priority; or the second service priority is higher than the lowest priority of the first service priority and the first auxiliary priority; or the second service priority is higher than the first auxiliary priority.

[0018] In the second condition described above, during the resource sensing and resource selection process, the first terminal may exclude resources used for sideline transmission services corresponding to a higher-level second service priority, or avoid excluding resources used for sideline transmission services corresponding to a lower-level second service priority. This prevents the first terminal from assisting sideline transmissions of a third terminal with a lower priority, or encourages the first terminal to assist sideline transmissions of a third terminal with a higher priority.

[0019] For scenario three, the above-mentioned first terminal excludes the resources corresponding to the second business priority or the second auxiliary priority from the candidate resources of the first terminal based on the first information and the second information, and may also include: if the third condition is met, the first terminal excludes the resources corresponding to the second business priority or the second auxiliary priority from the candidate resources of the first terminal. Among them, the third condition may include one or more of the following: the second service priority is higher than the first service priority; or, the second service priority is equal to the first service priority and the first auxiliary priority is lower than the first priority threshold; or, the first reference signal receiving power is greater than the first power threshold; or, the first reference signal receiving power is equal to the first power threshold and the first auxiliary priority is lower than the first priority threshold; or, the second service priority is higher than the first service priority and the first auxiliary priority is lower than the first priority threshold; or, the first reference signal receiving power is greater than the first power threshold and the first auxiliary priority is lower than the first priority threshold; or, the second service priority is equal to the first service priority and the first auxiliary priority is lower than the second auxiliary priority; or, the first reference signal receiving power is equal to the first power threshold and the first auxiliary priority is lower than the second auxiliary priority; or, the second service priority is higher than the highest level of priority between the first service priority and the first auxiliary priority; or, the first reference signal receiving power is greater than the first power threshold and the second service priority is higher than the first auxiliary priority; or, the second service priority is higher than the lowest level of priority between the first service priority and the first auxiliary priority; or higher than the first auxiliary priority; or, the highest level of priority among the second business priority and the second auxiliary priority is higher than the highest level of priority among the first business priority and the first auxiliary priority; or, the first reference signal received power is greater than the first power threshold, and the highest level of priority among the second business priority and the second auxiliary priority is higher than the first auxiliary priority; or, the highest level of priority among the second business priority and the second auxiliary priority is higher than the lowest level of priority among the first business priority and the first auxiliary priority; or, the highest level of priority among the second business priority and the second auxiliary priority is higher than the first auxiliary priority; or, the lowest level of priority among the second business priority and the second auxiliary priority is higher than the highest level of priority among the first business priority and the first auxiliary priority; or, the first reference signal received power is greater than the first power threshold, and the lowest level of priority among the second business priority and the second auxiliary priority is higher than the first auxiliary priority; or, the lowest level of priority among the second business priority and the second auxiliary priority is higher than the first auxiliary priority.

[0020] In the third condition above, during the process of resource perception and resource selection, the first terminal may exclude resources for the side transmission service corresponding to the second service priority of a higher level, or exclude resources for the auxiliary side transmission service corresponding to the second auxiliary priority of a higher level, so that the second terminal can use the resources corresponding to the second service priority or the second auxiliary priority to assist the side transmission of the fourth terminal. The first terminal may also avoid excluding resources for the side transmission service corresponding to the second service priority of a lower level, or avoid excluding resources for the auxiliary side transmission service corresponding to the second auxiliary priority of a lower level, so that the second terminal cannot use the resources corresponding to the second service priority or the second auxiliary priority to assist the side transmission of the fourth terminal. Accordingly, the first terminal may also be prevented from using the corresponding resources to assist the side transmission of the third terminal, or the first terminal may be encouraged to use the corresponding resources to assist the side transmission of the third terminal.

[0021] For scenario one, the first terminal seizes the resources corresponding to the second service priority or the second auxiliary priority according to the first information and the second information, and may also include: if the fourth condition is met, the first terminal seizes the resources corresponding to the second service priority or the second auxiliary priority. Among them, the fourth condition may include one or more of the following: the second service priority is lower than the second priority threshold and lower than the first service priority; it should be noted that the second priority threshold is preset to assist in determining whether the second service priority meets the preemption conditions; or, the second service priority is lower than the second priority threshold and the second service priority is equal to the first service priority and the second auxiliary priority is lower than the first priority threshold; or, the second service priority is lower than the second priority threshold and lower than the first service priority, and the second auxiliary priority is lower than the first priority threshold; or, the second service priority is lower than the second priority threshold and the first service priority, and the second auxiliary priority is lower than the first priority threshold; or, the second service priority is lower than the second priority threshold, and the first service priority is higher than the lowest priority of the second service priority and the second auxiliary priority; or, the second service priority is lower above the second priority threshold, and the first business priority is higher than the highest priority of the second business priority and the second auxiliary priority; or, the second priority threshold and the lowest priority of the first business priority are higher than the highest priority of the second business priority and the second auxiliary priority; or, the second priority threshold and the highest priority of the first business priority are higher than the highest priority of the second business priority and the second auxiliary priority; or, the second priority threshold and the lowest priority of the first business priority are higher than the lowest priority of the second business priority and the second auxiliary priority; or, the second priority threshold and the highest priority of the first business priority are higher than the lowest priority of the second business priority and the second auxiliary priority.

[0022] In the fourth condition described above, during the resource perception and resource selection process, the first terminal may avoid preempting resources for sideline transmission services corresponding to a higher-level second service priority, or avoid preempting resources for auxiliary sideline transmission services corresponding to a higher-level second auxiliary priority. The first terminal may preempt resources for sideline transmission services corresponding to a lower-level second service priority, or preempt resources for auxiliary sideline transmission services corresponding to a lower-level second auxiliary priority. This allows the second terminal, acting as an auxiliary terminal, to use the corresponding resources to assist the fourth terminal's sideline transmission, or to avoid using the corresponding resources to assist the fourth terminal's sideline transmission.

[0023] For scenario 2, the first terminal preempting resources corresponding to the second service priority or the second auxiliary priority based on the first information and the second information may further include: if a fifth condition is met, the first terminal preempting resources corresponding to the second service priority. The fifth condition may include one or more of the following: the second service priority is lower than the second priority threshold and lower than the first service priority; or the second service priority is lower than the second priority threshold and the second service priority is equal to the first service priority and the first auxiliary priority is higher than the first priority threshold; or the second service priority is lower than the second priority threshold and the first auxiliary priority is higher than the first priority threshold; or the second service priority is lower than the second priority threshold and lower than the first service priority, and the first auxiliary priority is higher than the first priority threshold; or the second service priority is lower than the second priority threshold and the highest priority of the first service priority and the first auxiliary priority is higher than the second service priority; or the second service priority is lower than the second priority threshold and the lowest priority of the first service priority and the first auxiliary priority is higher than the second service priority; or the highest priority of the second priority threshold, the first service priority, and the first auxiliary priority is higher than the second service priority; or the lowest priority of the second priority threshold, the first service priority, and the first auxiliary priority is higher than the second service priority.

[0024] In the fifth condition described above, during the resource sensing and resource selection process, the first terminal may avoid preempting resources for sideline transmission services corresponding to higher-level second service priorities, and may preempt resources for sideline transmission services corresponding to lower-level second service priorities. This prevents the first terminal from assisting sideline transmissions of lower-priority third terminals, or encourages the first terminal to assist sideline transmissions of higher-priority third terminals.

[0025] For scenario three, the first terminal preempts the resources corresponding to the second business priority or the second auxiliary priority according to the first information and the second information, and may also include: if the sixth condition is met, the first terminal preempts the resources corresponding to the second business priority or the second auxiliary priority; wherein the sixth condition may include one or more of the following: the second business priority is lower than the second priority threshold and lower than the first business priority; or, the second business priority is lower than the second priority threshold and the second business priority is equal to the first business priority and the first auxiliary priority is higher than the first priority threshold; or, the second business priority is lower than the second priority threshold and the first auxiliary priority is higher than the first priority threshold; or, the second business priority is lower than the second priority threshold and the first business priority is higher than the second business priority and the first auxiliary priority is higher than the first priority threshold; or, the second business priority is lower than the second priority threshold and the second business priority is equal to the first business priority and the first auxiliary priority is higher than the second auxiliary priority; or, the second business priority is lower than the second priority threshold and and the lowest priority of the first business priority and the first auxiliary priority is higher than the second business priority; or, the highest priority of the second priority threshold, the first business priority and the first auxiliary priority is higher than the second business priority; or, the lowest priority of the second priority threshold, the first business priority and the first auxiliary priority is higher than the second business priority; or, the second business priority is lower than the second priority threshold, and the highest priority of the first business priority and the first auxiliary priority is higher than the highest priority of the second business priority and the second auxiliary priority; or, the second business priority is lower than the second priority threshold, and the lowest priority of the first business priority and the first auxiliary priority is higher than the highest priority of the second business priority and the second auxiliary priority; or, the second business priority is lower than the second priority threshold, and the highest priority of the first business priority and the first auxiliary priority is higher than the lowest priority of the second business priority and the second auxiliary priority; or, the second business priority is lower than the second priority threshold, and the highest priority of the first business priority and the first auxiliary priority is higher than the lowest priority of the second business priority and the second auxiliary priority.

[0026] In the sixth condition described above, during the resource perception and resource selection process, the first terminal may avoid preempting resources for the side transmission service corresponding to the second service priority of a higher level, or avoid preempting resources for the auxiliary side transmission service corresponding to the second auxiliary priority of a higher level, so that the second terminal may use the resources corresponding to the second service priority or the second auxiliary priority to assist the side transmission of the fourth terminal. The first terminal may preempt resources for the side transmission service corresponding to the second service priority of a lower level, or preempt resources for the auxiliary side transmission service corresponding to the second auxiliary priority of a lower level, so that the first terminal may use the resources corresponding to the second service priority or the second auxiliary priority to assist the side transmission of the third terminal. Accordingly, the first terminal may be prevented from using the corresponding resources to assist the side transmission of the third terminal, or the first terminal may be encouraged to use the corresponding resources to assist the side transmission of the third terminal.

[0027] In a second aspect, a resource configuration method is provided. The method includes: a fourth terminal obtaining a fourth service priority and a second auxiliary priority. The fourth service priority is the physical layer priority of the fourth terminal, and the second auxiliary priority is the priority that the second terminal uses to assist the fourth terminal in selecting sidelink transmission resources. The fourth terminal determines candidate resources for sidelink transmission based on the fourth service priority and the second auxiliary priority.

[0028] Optionally, the above-mentioned fourth terminal determines the candidate resources for side transmission of the fourth terminal based on the fourth service priority and the second auxiliary priority, which may include: if the fourth service priority is higher than or equal to the second auxiliary priority, the fourth terminal uses the resources corresponding to the second auxiliary priority as the candidate resources for side transmission of the fourth terminal.

[0029] It should be noted that in the resource configuration method provided in the second aspect, the third terminal may also obtain the third service priority and the first auxiliary priority. The third service priority is the physical layer priority of the third terminal, and the first auxiliary priority is the priority that the first terminal uses to assist the third terminal in selecting sidelink transmission resources. The third terminal determines candidate resources for sidelink transmission based on the third service priority and the first auxiliary priority. For the specific determination method, please refer to the candidate resource determination method for the fourth terminal described above and will not be repeated here.

[0030] Based on the resource configuration method provided in the second aspect, the fourth terminal determines the candidate resources for side transmission of the fourth terminal based on the obtained fourth service priority and the second auxiliary priority, or the third terminal determines the candidate resources for side transmission of the third terminal based on the obtained third service priority and the first auxiliary priority, and clarifies which terminals can use the auxiliary resources provided by the auxiliary terminal. Taking the second terminal assisting the fourth terminal as an example, when the fourth terminal's fourth service priority is low, the second terminal will provide fewer candidate resources to the fourth terminal, and even the candidate resources cannot be used by the fourth terminal. On the contrary, when the fourth terminal's fourth service priority is high, the second terminal will provide more candidate resources to the fourth terminal, so that the fourth terminal can obtain more candidate resources.

[0072] The network architecture and business scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided in the embodiments of the present application. Ordinary technicians in this field will know that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0073] In order to facilitate understanding of the embodiments of the present application, first Figure 1 Taking the schematic diagram of the architecture of a communication system as an example, the process of a first terminal assisting a third terminal in performing sidelink transmission is described.

[0074] For example, Figure 1 A schematic diagram of the architecture of a communication system applicable to a resource configuration method provided in an embodiment of the present application.

[0075] like Figure 1 As shown, the communication system includes multiple terminal devices, such as a first terminal, a third terminal and a fifth terminal.

[0076] A terminal device, also known as user equipment (UE), mobile station (MS), or mobile terminal (MT), provides voice and / or data connectivity to users. The terminal device can communicate with the core network via the radio access network (RAN), exchanging voice and / or data with the RAN. For example, a terminal device can be a handheld device, in-vehicle device, or vehicle user equipment with wireless connectivity. Currently, some examples of terminal devices include: mobile phones, tablets, laptops, PDAs, mobile internet devices (MIDs), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, wireless terminal devices in industrial control, wireless terminal devices in self-driving, wireless terminal devices in remote medical surgery, wireless terminal devices in smart grids, wireless terminal devices in transportation safety, wireless terminal devices in smart cities, and wireless terminal devices in smart homes. Terminal devices can communicate directly with each other via the PC5 interface. The direct communication link between terminal devices is called a sidelink (SL). Communication based on the sidelink may use at least one of the following channels: a physical sidelink shared channel (PSSCH), used to carry data; and a physical sidelink control channel (PSCCH), used to carry sidelink control information (SCI).

[0077] Optionally, the communication system further includes a network device for providing timing synchronization and resource scheduling for the terminal device. The network device can communicate with at least one terminal device (such as the first terminal) via a Uu interface. The network device is a device in the network used to access the terminal device to the wireless network. The network device can be a node in a wireless access network, which can also be called a base station, or a radio access network (RAN) node (or device). The network device can be used to convert received air frames into and from Internet Protocol (IP) packets, and act as a router between the terminal device and the rest of the access network, where the rest of the access network may include an IP network. The network device can also coordinate attribute management of the air interface. For example, the network device may include an evolved base station (NodeB or eNB or e-NodeB, evolutionaryNode B) in a long term evolution (LTE) system or an evolved LTE system (LTE-Advanced, LTE-A), such as a traditional macro base station eNB and a micro base station eNB in ​​a heterogeneous network scenario, or may also include a next generation node B (gNB) in a fifth generation mobile communication technology (5th generation, 5G) new radio (NR) system, or may also include a transmission reception point (TRP), a home base station (for example, a home evolved NodeB, or a home Node B, HNB), a baseband unit (BBU), a baseband pool BBU pool, or a WiFi access point (AP), etc., or may also include a centralized unit (CU) and a distributed unit (DU) in a cloud radio access network (CloudRAN) system, which is not limited in the embodiments of the present application.

[0078] exist Figure 1 In the communication system, the third terminal and the fifth terminal perform sidelink (SL) communication. Before the third terminal and the fifth terminal perform SL communication, the first terminal can assist the third terminal in resource perception and resource selection, and send the results of resource perception and resource selection to the third terminal. The third terminal can use the results of resource perception and resource selection of the first terminal as candidate resources to perform SL communication with the fifth terminal.

[0079] It should be understood that the first terminal assists the third terminal in resource perception and resource selection, which means that the first terminal can suggest or instruct the third terminal to use certain resources, and the third terminal can determine whether to use the above resources based on the suggestion or instruction of the first terminal.

[0080] Figure 2 Schematic diagram of the communication method provided in this embodiment Figure 1 .like Figure 2 As shown, taking the case where the first terminal assists the third terminal based on a trigger mechanism as an example, the specific process of the communication method can be expressed as follows:

[0081] S201: The third terminal sends assistance request information to the first terminal. The assistance request information includes a priority for assisting the third terminal in selecting resources for SL communication transmission.

[0082] S202: When the first terminal receives the assistance request information from the third terminal, the first terminal sends a request reply to the third terminal.

[0083] S203: The first terminal performs resource perception.

[0084] S204: The first terminal sends a result of resource sensing, ie, assistant information (ASI), to the third terminal.

[0085] S205: The third terminal performs resource perception and resource selection, and combines the received auxiliary information ASI with the result of its own resource perception and resource selection as candidate resources for SL communication with the fifth terminal.

[0086] S206: The third terminal selects time-frequency resources from the candidate resources to perform SL communication with the fifth terminal.

[0087] S207: The fifth terminal sends a hybrid automatic repeat request to the sixth terminal.

[0088] S208: The third terminal reselects time-frequency resources to perform SL communication with the fifth terminal.

[0089] S209: The third terminal sends a resource reselection request to the first terminal, and re-executes the above steps S202 to S208.

[0090] It should be noted that, in the above steps S207 and S208 can be repeated multiple times.

[0091] Furthermore, after introducing the aforementioned assistance process, the assisting terminal, i.e., the first terminal, can perform resource awareness from a wider range of perspectives. For example, it can detect that certain resources are occupied by another terminal and transmit this information to the assisted terminal, i.e., the third terminal, via assistance information, thereby reducing the possibility of resource conflicts and interference. However, when the first terminal assists the third terminal, the process of the third terminal sending an assistance request to the first terminal and the first terminal sending assistance information to the third terminal consumes a significant amount of time-frequency resources during the entire communication process. In other words, the entire process of the first terminal assisting the third terminal increases resource utilization, i.e., increases the channel busy ratio (CBR) in the communication system. Therefore, in order to ensure that the assistance provided by a terminal to another terminal is of higher value after introducing a resource awareness scheme in which an assisting terminal assists other terminals, the assistance provided by a terminal to another terminal must be of higher value, i.e., the assistance must be targeted at sideline transmissions with higher service priority. Furthermore, when a terminal assists another terminal, the assistance information sent must minimize interference with normal sideline transmissions.

[0092] In order to solve the above problems, the embodiment of the present application provides a technical solution for assisting resource configuration for side transmission. Figures 3 to 8 , describe the technical solution provided in this application.

[0093] Figure 3 This is a schematic diagram of the inter-terminal SL communication scenario provided in this embodiment. Please refer to Figure 3 , the first, second, third, fourth, fifth, and sixth terminals can use resources from the same resource pool. The first terminal can function as a normal terminal for sideline transmission with the fifth terminal, or as an auxiliary terminal, assisting the third and fifth terminals in sideline transmission. The second terminal can function as a normal terminal for sideline transmission with the sixth terminal, or as an auxiliary terminal, assisting the fourth and sixth terminals in sideline transmission.

[0094] Figure 4 For this embodiment Figure 3 Schematic diagram of the process applicable to the communication scenario shown Figure 2 Specifically, in the resource pool corresponding to the communication diagram, no matter whether the first terminal is a normal terminal or an auxiliary terminal, and the second terminal is a normal terminal or an auxiliary terminal, the first terminal can perceive the resources used by the second terminal for side transmission or the resources used by the second terminal to assist the fourth terminal in side transmission during the resource perception process. Therefore, by determining the candidate resources of the first terminal, that is, excluding or preempting them, the second terminal can perceive whether the required resources are occupied, thereby avoiding the auxiliary terminal from assisting lower priority side transmissions, and encouraging the auxiliary terminal to assist higher priority side transmissions.

[0095] It should be noted that the reference Figure 4 In the communication flow diagram, if the first terminal is an ordinary terminal, the ordinary terminal described in this application is a terminal that does not assist other terminals in side transmission, relative to the auxiliary terminal. In this case, the time nodes involved in the method in this embodiment can be the following three situations: ① When the ordinary terminal sends an auxiliary request to the auxiliary terminal, for example, when the fourth terminal sends an auxiliary request to the second terminal; ② When the auxiliary terminal sends auxiliary information to the ordinary terminal, for example, when the second terminal sends auxiliary information to the fourth terminal; ③ When the ordinary terminal sends a resource reselection request to the auxiliary terminal, for example, when the fourth terminal sends a resource reselection request to the second terminal.

[0096] If the first terminal acts as an auxiliary terminal, the time nodes involved in the method in this embodiment may be the following cases in addition to the three cases when the first terminal acts as an auxiliary terminal: ④ When side transmission data is sent between terminals, for example, when the fourth terminal sends side transmission data to the sixth terminal.

[0097] The following describes a method for performing resource configuration using the first terminal as the execution subject. Figure 5 A schematic diagram of the flow of the resource configuration method of this embodiment is shown.

[0098] like Figure 5 As shown, the resource configuration method includes S501 and S502:

[0099] S501: A first terminal obtains first information and second information.

[0100] Among them, the first information includes a first service priority and / or a first auxiliary priority. The first service priority is the physical layer priority of the first terminal, that is, the priority corresponding to the first terminal sending PSSCH to the third terminal and / or the fifth terminal. The first auxiliary priority is the priority for the first terminal to assist the third terminal in selecting side transmission resources. It should be noted that the first auxiliary priority can be the priority for the first terminal to send auxiliary information to the third terminal for the third terminal to select auxiliary resources. The first auxiliary priority can also be the priority carried by the third terminal when sending an auxiliary request to the first terminal for assisting the third terminal in selecting resources for side transmission. The first auxiliary priority can be the physical layer priority for the side transmission from the third terminal to the fifth terminal.

[0101] Among them, the second information includes a second service priority and / or a second auxiliary priority. The second service priority is the physical layer priority of the second terminal, that is, the priority corresponding to the second terminal sending PSSCH to the fourth terminal / or the sixth terminal. The second auxiliary priority is the priority for the second terminal to assist the fourth terminal in selecting side transmission resources. It should be noted that the second auxiliary priority can be the priority for the second terminal to send auxiliary information to the fourth terminal for the third terminal to select auxiliary resources. The second auxiliary priority can also be the priority carried by the fourth terminal when sending an auxiliary request to the second terminal for assisting the third terminal in selecting resources for side transmission. The second auxiliary priority can be the physical layer priority of the side transmission from the fourth terminal to the sixth terminal.

[0102] It should be understood that the above-mentioned service priority can also be called L1 priority (L1priority), physical layer priority, priority carried in SCI, priority corresponding to PSSCH carried in SCI, priority of sending PSSCH, priority of logical channel, and the highest level priority of logical channel.

[0103] It should be noted that the first service priority, the first auxiliary priority, the second service priority and the second auxiliary priority are all carried by sidelink control information (SCI).

[0104] In addition, it should be noted that the first information is determined by the first terminal. The first service priority is determined based on the physical layer parameters of the first terminal itself. The first auxiliary priority can be determined based on the upper layer parameters of the first terminal, or based on the auxiliary request sent by the third terminal received by the first terminal. The second information is received from the second terminal. During the resource perception process, the first terminal can perceive the auxiliary information data transmission packet sent by the second terminal to the fourth terminal. The data transmission packet will carry relevant priority information, including the second service priority and the second auxiliary priority. In addition, the first terminal can also perceive the data transmission packet for side transmission between the second terminal and the sixth terminal. The data transmission packet will carry information about the second service priority. Therefore, the first terminal can receive the second service priority and the second auxiliary priority sent by the second terminal during the resource perception process.

[0105] For example, according to Figure 3 As shown in the communication diagram, when the auxiliary terminal assists other terminals in resource perception, the specific scheme of resource configuration can be divided into the following three scenarios for description.

[0106] Figure 6 Shown Figure 3 Example 1 of the communication scenario shown, such as Figure 6As shown, the first terminal acts as a normal terminal to perform SL communication with the fifth terminal, and the second terminal acts as an auxiliary terminal to assist the fourth terminal in performing SL communication with the sixth terminal. Therefore, the first information includes the first service priority; the second information includes the second service priority and the second auxiliary priority.

[0107] Figure 7 Shown Figure 3 Example 2 of the communication scenario shown, such as Figure 7 As shown, the first terminal acts as an auxiliary terminal to assist the third terminal and the fifth terminal in sideline transmission, and the second terminal acts as a normal terminal to perform SL communication with the sixth terminal. Therefore, the first information includes the first service priority and the first auxiliary priority; the second information includes the second service priority.

[0108] Figure 8 Shown Figure 3 Example 3 of the communication scenario shown, such as Figure 8 As shown, the first terminal acts as an auxiliary terminal to assist the third terminal in SL communication with the fifth terminal, and the second terminal acts as an auxiliary terminal to assist the fourth terminal in SL communication with the sixth terminal. Therefore, the first information includes the first service priority and the first auxiliary priority; the second information includes the second service priority and the second auxiliary priority.

[0109] S502: The first terminal determines a candidate resource of the first terminal according to the first information and the second information.

[0110] It should be noted that the purpose of the candidate resources of the first terminal determined in this step varies depending on the role of the first terminal. That is, when the first terminal is a normal terminal, the candidate resources of the first terminal are used for the sideline transmission service of the first terminal as candidate resources for sideline transmission of the first terminal; when the first terminal is an auxiliary terminal, the candidate resources of the first terminal are used for the sideline transmission service of the first terminal and / or the sideline transmission service of a third terminal assisted by the first terminal.

[0111] Optionally, in step S502, the first terminal determining the candidate resource of the first terminal according to the first information and the second information may include two sub-steps:

[0112] Step 1: The first terminal excludes resources corresponding to the second service priority or the second auxiliary priority from candidate resources of the first terminal according to the first information and the second information.

[0113] Step 2: The first terminal seizes resources corresponding to the second service priority or the second auxiliary priority according to the first information and the second information.

[0114] It is worth noting that the corresponding resources described in this application include one or more of currently perceived resources, retransmission reserved resources indicated in the sidelink control information, and periodically reserved resources.

[0115] Of course, the first terminal also obtains the first reference signal receiving power and the first power threshold; wherein the first power threshold is associated with the priority of the service. It should be noted that the first reference signal receiving power is measured by the first terminal. The first power threshold is a threshold in a threshold list determined by the upper layer parameters of the first terminal, which corresponds to two priorities, one priority is determined by the upper layer parameters of the first terminal, and the other priority is the priority obtained by SCI demodulation. In this way, the first reference signal receiving power reached by the first terminal can be compared with the first power threshold. By comparing these two parameters, it can be determined whether the first terminal needs to exclude or seize the resources used or reserved by the second terminal, so that when the first terminal assists the third terminal in side transmission, the first terminal has more resources to transmit auxiliary information.

[0116] In addition, the first terminal also obtains a first priority threshold and / or a second priority threshold, wherein both the first priority threshold and the second priority threshold can be indicated by upper-layer parameters or configured through Radio Resource Control (RRC) signaling. The first priority threshold is used to assist in determining whether the conditions for excluding the resources corresponding to the second auxiliary priority are met. The second priority threshold is used to assist in determining whether the conditions for preempting the resources corresponding to the second service priority are met. Among them, the first priority threshold can be equal to the second priority threshold. That is to say, the first priority threshold and the second priority threshold can be indicated by the same upper-layer parameter, or configured by the same RRC signaling. It should be understood that the first priority threshold and the second priority threshold can be activated or deactivated on the resource pool, and the first priority threshold and the second priority threshold can be integers from 1 to 8, or integers from 0 to 7. If the smallest value represents the highest priority level, then 1 or 0 represents the highest priority level.

[0117] For example, Figures 6 to 8 Taking the illustrated scenario as an example, how the first terminal determines the candidate resources of the first terminal according to the first information and the second information is described in detail.

[0118] First, assume that the first service priority is P j , the first auxiliary priority is P D , the second service priority is P i , the second auxiliary priority is P A , the first reference signal received power is RSRP i , the first power threshold is Th(P Rx ), the first priority threshold is P AS , the second priority threshold is P p .

[0119] It should be understood that in the following priority comparison, what is compared is the priority level. The priority level and the priority value have a certain correspondence, for example, the higher the priority level, the lower the corresponding priority value, and vice versa. Taking the higher the priority level, the lower the corresponding priority value as an example, the priority value range can be an integer from 1 to 8 or an integer from 0 to 7. If the priority value range is 1 to 8, then a priority value of 1 represents the highest level of priority.

[0120] In step 1, corresponding to Figure 6 In the example scenario shown, if the first condition is met, the first terminal excludes the resource corresponding to the second service priority from the candidate resources of the first terminal. The first condition may be:

[0121] Option 1: The second service priority is higher than the first service priority, or the second service priority is equal to the first service priority and the second auxiliary priority is higher than the first priority threshold, that is, this option can be expressed as: P i >P j or (P i =P j And P A >P AS ). In this option, the second service priority is compared with the first service priority. When the second service priority is higher than the first service priority, the first terminal excludes the resources corresponding to the second service priority. Moreover, when the first service priority is equal to the second service priority, if the second auxiliary priority is higher than the first priority threshold, the first terminal excludes the resources corresponding to the second auxiliary priority. Since the first terminal excludes the corresponding resources, the second terminal can use the resources to provide assistance to the side transmission service of the fourth terminal with a higher priority, that is, the second terminal sends auxiliary information to the fourth terminal with more candidate resources.

[0122] Option 2: The first reference signal received power is greater than the first power threshold, or the first reference signal received power is equal to the first power threshold and the second auxiliary priority is higher than the first priority threshold; that is, this option can be expressed as: RSRP i >Th(P Rx ) or (RSRP i =Th(P Rx ) and P A >P AS). In this option, the first reference signal received power is compared with the first power threshold. When the first reference signal received power is greater than the first power threshold, the first terminal excludes the resources corresponding to the second service priority. And when the first reference signal received power is equal to the first power threshold, if the second auxiliary priority is higher than the first priority threshold, the first terminal excludes the resources corresponding to the second auxiliary priority. Since the first terminal excludes the corresponding resources, the second terminal can use the resources to provide assistance for the side transmission service of the fourth terminal with a higher priority, that is, the second terminal sends auxiliary information to the fourth terminal with more candidate resources.

[0123] Option 3: The second service priority is higher than the first service priority and the second auxiliary priority is higher than the first priority threshold; that is, this option can be expressed as: P i >P j And P A >P AS For this option, please refer to the analysis of option 1 and will not be repeated here.

[0124] Option 4: The first reference signal received power is greater than the first power threshold and the second auxiliary priority is higher than the first priority threshold; that is, this option can be expressed as: RSRP i >Th(P Rx ) and P A >P AS For this option, please refer to the analysis of option 2 and will not be repeated here.

[0125] Option 5: The first level of priority among the second service priority and the second auxiliary priority is higher than the first service priority; that is, this option can be expressed as: min{P i ,P A}>P j . Please refer to option five in Table 1. In this option, the judgment of the second auxiliary priority and the first business priority is added on the basis of option one, that is, when the second business priority and the second auxiliary priority are both higher than the first business priority, the first terminal excludes the resources corresponding to the second business priority. According to the judgment of option one, as long as the second business priority is higher than the first business priority, the first terminal directly excludes the resources corresponding to the second business priority. After adding this condition, under the condition that the second business priority is higher than the first business priority, if the second auxiliary priority is lower than the first business priority, the first terminal does not exclude the resources corresponding to the second auxiliary priority. Therefore, the second terminal cannot use the resources corresponding to the second auxiliary priority to provide assistance to the side transmission service of the fourth terminal with a lower priority.

[0126] Option 6: The first reference signal received power is greater than the first power threshold and the second auxiliary priority is higher than the first service priority; that is, this option can be expressed as: RSRP i >Th(P Rx ) and P A >P j For this option, please refer to the analysis of option 5 and will not be repeated here.

[0127] Table 1

[0128]

[0129]

[0130] Option 7: The highest priority of the second service priority and the second auxiliary priority is higher than the first service priority; that is, this option can be expressed as: max{P i ,P A}>P j . In this option, as long as there is a situation where the second service priority or the second auxiliary priority is higher than the first service priority, the first terminal excludes the resources corresponding to the second service priority. Please refer to option seven in Table 1. Compared with option one, it adds that as long as there is a situation where the second auxiliary priority is higher than the first service priority, the first terminal excludes the resources corresponding to the second auxiliary priority. Therefore, when the priority of the second auxiliary priority is higher, the first terminal excludes the corresponding resources, and the second terminal can use the corresponding resources to provide assistance to the side transmission service of the fourth terminal with a higher priority.

[0131] Option 8: The first reference signal received power is greater than the first power threshold or the second auxiliary priority is higher than the first service priority. That is, this option can be expressed as: RSRP i >Th(P Rx ) or P A >P j For this option, please refer to the analysis of option seven and will not be repeated here.

[0132] In step 1, corresponding to Figure 7 In the scenario shown, if the second condition is met, the first terminal excludes the resource corresponding to the second service priority from the candidate resources of the first terminal. The second condition may be:

[0133] Option 1: The second service priority is higher than the first service priority, or the second service priority is equal to the first service priority and the first auxiliary priority is lower than the first priority threshold; that is, this option can be expressed as P i >P j or (P i =P j And P D <PAS In this option, the second service priority is compared with the first service priority. If the second service priority is higher than the first service priority, the first terminal excludes the resources corresponding to the second service priority. Furthermore, if the first service priority is equal to the second service priority, but the first auxiliary priority is lower than the first priority threshold, the first terminal excludes the resources corresponding to the second service priority. Because the first auxiliary priority is lower, the first terminal excludes the corresponding resources, thereby preventing the first terminal from using these resources to provide assistance to the sideline transmission service of a third terminal with a lower priority level.

[0134] Option 2: The first reference signal received power is greater than the first power threshold, or the first reference signal received power is equal to the first power threshold and the first auxiliary priority is lower than the first priority threshold; that is, this option can be expressed as RSRP i >Th(P Rx ) or (RSRP i =Th(P Rx ) and P D <P AS ). Please refer to the analysis of Option 1 for this option and will not be repeated here.

[0135] Option 3: The second service priority is higher than the first service priority and the first auxiliary priority is lower than the first priority threshold; that is, this option can be expressed as P i >P j And P D <P AS For this option, please refer to the analysis of option 1 and will not be repeated here.

[0136] Option 4: The first reference signal received power is greater than the first power threshold and the first auxiliary priority is lower than the first priority threshold; that is, this option can be expressed as RSRP i >Th(P Rx ) and P D <P AS For this option, please refer to the analysis of option 1 and will not be repeated here.

[0137] Option 5: The second service priority is higher than the highest priority among the first service priority and the first auxiliary priority; that is, this option can be expressed as P i >max{P j ,P D}. Please refer to option five in Table 2. In this option, the judgment of the first auxiliary priority and the second business priority is added on the basis of option one, that is, when the second business priority is higher than the first business priority and the first auxiliary priority at the same time, the first terminal excludes the resources corresponding to the second business priority. According to the judgment of option one, as long as the second business priority is higher than the first business priority, the first terminal directly excludes the resources corresponding to the second business priority. Under the condition that the second business priority is higher than the first business priority, if the second business priority is lower than the first auxiliary priority, the first terminal does not exclude the resources corresponding to the second business priority. At this time, the first auxiliary priority is relatively high. Therefore, the first terminal can use the resources corresponding to the second business priority to provide assistance to the side transmission service of the third terminal with a higher priority, that is, the first terminal has more candidate resources when sending auxiliary information to the third terminal.

[0138] Option 6: The first reference signal received power is greater than the first power threshold and the second service priority is higher than the first auxiliary priority; that is, this option can be expressed as RSRP i >Th(P Rx ) and P i >P D For this option, please refer to the analysis of option 5 and will not be repeated here.

[0139] Option 7: The second service priority is higher than the lowest priority of the first service priority and the first auxiliary priority; that is, this option can be expressed as P i >min{P j ,P D}. In this option, as long as there is a situation where the second service priority is higher than the first auxiliary priority or higher than the first service priority, the first terminal excludes the resources corresponding to the second service priority. Please refer to option seven in Table 2. Compared with option one, it adds that as long as there is a situation where the first auxiliary priority is lower than the second service priority, the first terminal excludes the resources corresponding to the second service priority. That is, corresponding to option one, there is a situation in option five where the second service priority is lower than the first service priority. If the second service priority is higher than the first auxiliary priority, the first terminal excludes the resources corresponding to the second service priority. Therefore, the first terminal cannot use the resources corresponding to the second service priority to provide assistance to the side transmission service of the third terminal with a lower priority.

[0140] Option 8: The first reference signal received power is greater than the first power threshold, or the second service priority is higher than the first auxiliary priority; that is, this option can be expressed as RSRP i >Th(P Rx ) or P i >P D; Please refer to the analysis of option five for this option and will not be repeated here.

[0143] In step 1, corresponding to Figure 8 In the scenario shown, if the third condition is met, the first terminal excludes the resource corresponding to the second service priority from the candidate resources of the first terminal. The third condition may be:

[0144] Option 1: The second service priority is higher than the first service priority, or the second service priority is equal to the first service priority and the first auxiliary priority is lower than the first priority threshold; that is, this option can be expressed as P i >P j or (P i =P j And P D <P AS ). For this option, please refer to Figure 7 Option 1 in Scenario 2 is shown and will not be described again here.

[0148] Option 5: The second service priority is equal to the first service priority and the first auxiliary priority is lower than the second auxiliary priority; that is, this option can be expressed as P i >P j or (P i =P j And P D <P A ). In this option, based on Option 1, it is added that when the second service priority is equal to the first service priority, if the first auxiliary priority is lower than the second auxiliary priority, the condition that the first terminal excludes the resources corresponding to the second service priority is met. Since in this scenario, the first terminal and the second terminal are both auxiliary terminals, respectively assisting the third terminal and the fourth terminal in performing side transmission services. Therefore, when the second auxiliary priority is higher than the first auxiliary priority, the first terminal should exclude the resources corresponding to the second auxiliary priority. Thereby, the second terminal can use the resources to provide assistance to the side transmission service of the fourth terminal with a higher priority, that is, to satisfy the condition that the auxiliary terminal assists the side transmission service with a higher priority as much as possible.

[0149] Option 6: The first reference signal received power is equal to the first power threshold and the first auxiliary priority is lower than the second auxiliary priority; that is, this option can be expressed as RSRP i >Th(P Rx ) or (RSRP i =Th(P Rx ) and P D <P A ). This option is similar to option 5 and will not be described here.

[0150] Option 7: The second service priority is higher than the highest priority among the first service priority and the first auxiliary priority; that is, this option can be expressed as P i >max{P j ,P D}. For this option, please refer to Figure 7 Option 5 in Scenario 2 is shown and will not be described again here.

[0151] Option 8: The first reference signal received power is greater than the first power threshold and the second service priority is higher than the first auxiliary priority; that is, this option can be expressed as RSRP i >Th(P Rx ) and P i >P D For this option, please refer to Figure 7 Option 5 in Scenario 2 is shown and will not be described again here.

[0152] Option 9: The second service priority is higher than the lowest priority of the first service priority and the first auxiliary priority; that is, this option can be expressed as P i >min{P j ,P D}. For this option, please refer to Figure 7 Option 7 in Scenario 2 is shown and will not be described again here.

[0153] Option 10: The second service priority is higher than the first auxiliary priority; that is, this option can be expressed as RSRP i >Th(P Rx ) or P i >P D For this option, please refer to Figure 7 Option 7 in Scenario 2 is shown and will not be described again here.

[0154] Option 11: The highest priority among the second service priority and the second auxiliary priority is higher than the highest priority among the first service priority and the first auxiliary priority; that is, this option can be expressed as max{P i ,P A}>max{P j ,P D Please refer to Option 11 in Table 3. Compared to Option 1, this option adds the following: if the second service priority is higher than the first service priority, but the second service priority is lower than the first auxiliary service priority, the first terminal will not exclude the resources corresponding to the second service priority. In other words, the first terminal can use the resources corresponding to the second service priority to assist the sidelink transmission service of the third terminal, thereby providing the first terminal with more candidate resources when sending auxiliary information to the third terminal.

[0155] Option 12: The first reference signal received power is greater than the first power threshold, and the highest priority of the second service priority and the second auxiliary priority is higher than the first auxiliary priority; that is, this option can be expressed as RSRP i >Th(P Rx ) and max{P i ,P A}>P D For this option, please refer to Option 11 and will not be described in detail here.

[0156] Option 13: The highest priority among the second service priority and the second auxiliary priority is higher than the lowest priority among the first service priority and the first auxiliary priority; that is, this option can be expressed as max{P i ,P A}>min{P j ,P DPlease refer to Option 13 in Table 3. Compared to Option 1, this option adds the following: If the second service priority is lower than the first service priority, but the second service priority is higher than the first auxiliary priority, the first terminal excludes the resources corresponding to the second service priority. Therefore, the first terminal cannot use the resources corresponding to the second service priority to assist the sidelink transmission service of the third terminal.

[0157] Option 14: The highest priority of the second service priority and the second auxiliary priority is higher than the first auxiliary priority; that is, this option can be expressed as RSRP i >Th(P Rx ) or max{P i ,P A}>P D For this option, please refer to the analysis of option 13 and will not be repeated here.

[0159]

[0160] Option 15: The lowest priority level among the second service priority level and the second auxiliary priority level is higher than the highest priority level among the first service priority level and the first auxiliary priority level; that is, this option can be expressed as min{P i ,P A}>max{P j ,P D Please refer to Option 15 in Table 3. Compared to Option 1, this option adds the following: If the second service priority is higher than the first service priority, but the second service priority is lower than the first auxiliary service priority, the first terminal does not exclude the resources corresponding to the second service priority. In other words, the first terminal can use the resources corresponding to the second service priority to assist the sidelink transmission service of the third terminal, thereby providing the first terminal with more candidate resources when sending auxiliary information to the third terminal.

[0161] Option 16: The first reference signal received power is greater than the first power threshold, and the lowest priority of the second service priority and the second auxiliary priority is higher than the first auxiliary priority; that is, this option can be expressed as RSRP i >Th(P Rx ) and min{P i ,P A}>P D For this option, please refer to the analysis of option 15 and will not be repeated here.

[0162] Option 17: The lowest priority level among the second service priority level and the second auxiliary priority level is higher than the lowest priority level among the first service priority level and the first auxiliary priority level; that is, this option can be expressed as min{Pi ,P A}>min{P j ,P D Please refer to Option 17 in Table 3. Compared to Option 1, this option adds the following: If the second service priority is lower than the first service priority, but the second service priority is higher than the first auxiliary priority, the first terminal excludes the resources corresponding to the second service priority. Therefore, the first terminal cannot use the resources corresponding to the second service priority to assist the sidelink transmission service of the third terminal.

[0163] Option 18: The first reference signal received power is greater than the first power threshold, or the lowest priority of the second service priority and the second auxiliary priority is higher than the first auxiliary priority; that is, this option can be expressed as RSRP i >Th(P Rx ) or min{P i ,P A}>P D For this option, please refer to the analysis of option 17 and will not be repeated here.

[0164] In step 2, corresponding to Figure 6 In the scenario shown, if the fourth condition is met, the first terminal preempts the resources corresponding to the second service priority. The fourth condition may be:

[0165] Option 1: The second service priority is lower than the second priority threshold and lower than the first service priority, or the second service priority is lower than the second priority threshold and the second service priority is equal to the first service priority and the second auxiliary priority is lower than the first priority threshold; that is, this option can be expressed as (P i <P p And P j >P i ) or (P i <P p And P i =P j And P A <P AS). In this option, the second service priority is compared with the second priority threshold and the first service priority. If the second service priority is lower than the second priority threshold and the first service priority at the same time, the resources corresponding to the second service priority are seized. If the second service priority is lower than the second priority threshold and the second service priority is equal to the first service priority, the relationship between the second auxiliary priority and the first priority threshold is compared. If the second auxiliary priority is lower, the resources corresponding to the second service priority and the second auxiliary priority are seized. Therefore, when the level of the second auxiliary priority is low, the second terminal is prevented from using the resources corresponding to the second auxiliary priority to provide assistance to the side transmission service of the fourth terminal.

[0166] Option 2: The second service priority is lower than the second priority threshold and lower than the first service priority, and the second auxiliary priority is lower than the first priority threshold; that is, this option can be expressed as P i <P p And P j >P i And P A <P AS For this option, please refer to the analysis of Option 1 and will not be repeated here.

[0167] Table 4

[0168]

[0169]

[0170] Option 3: The second service priority is lower than the second priority threshold, and the first service priority is higher than the lowest priority of the second service priority and the second auxiliary priority; that is, this option can be expressed as P i <P p And P j >min{P i ,P A Please refer to Option 3 in Table 4. This option, based on Option 1, adds that if the first service priority is lower than the second service priority, but the first service priority is higher than the second auxiliary priority, the first terminal will preempt the resources corresponding to the second auxiliary priority. Therefore, if the second auxiliary priority level is lower, the second terminal is prevented from using the resources corresponding to the second auxiliary priority to assist the sidelink transmission service of the fourth terminal.

[0171] Option 4: The second service priority is lower than the second priority threshold, and the first service priority is higher than the highest priority of the second service priority and the second auxiliary priority; that is, this option can be expressed as P i <P p And Pj >max{P i ,P A Please refer to Option 4 in Table 4. This option, based on Option 1, adds that if the first service priority is higher than the second service priority, and the second auxiliary priority is higher than the first service priority, the first terminal will not preempt the resources corresponding to the second auxiliary priority. Therefore, the second terminal can use the resources corresponding to the second auxiliary priority to provide assistance to the sidelink transmission of the fourth terminal. In other words, the second terminal has more candidate resources for sending auxiliary information to the fourth terminal.

[0172] Option 5: The lowest priority level among the second priority threshold and the first service priority level is higher than the highest priority level among the second service priority level and the second auxiliary priority level; that is, this option can be expressed as min{P p ,P j}>max{P i ,P A Please refer to option 5 in Table 5. In this option, P is added compared to option 1. j >P A >P p >P i , P A >P j >P p >P i , P A >P p >P j >P i , P p >P A >P j >P i These four situations do not preempt the resources corresponding to the second auxiliary priority. That is, under the condition that the second priority threshold is higher than the second service priority, even if the priority level of the second service priority is very low, as long as there is a second auxiliary priority higher than the second priority threshold, or the second auxiliary priority is higher than the first service priority, the first terminal will not preempt the resources corresponding to the second auxiliary priority. Therefore, the second terminal can use the resources corresponding to the second auxiliary priority to provide assistance to the side transmission of the fourth terminal, that is, the second terminal has more candidate resources for sending auxiliary information to the fourth terminal.

[0173] Option 6: The highest priority among the second priority threshold and the first service priority is higher than the highest priority among the second service priority and the second auxiliary priority; that is, this option can be expressed as max{P p ,P j}>max{P i ,P APlease refer to option 6 in Table 5. In this option, compared with option 1, Pj>Pi>PA>Pp, P j >P i >P p >P A 、P j >P A >P i >P p 、P j <P i <P A <P p 、P j <P A <P i <P p 、P A <P j <P i <P p Six preemption situations. In these six preemption situations, if the second auxiliary priority P A If the second service priority is lower than the second priority threshold, the preemption condition is met; or if the first service priority is higher than both the second service priority and the second auxiliary priority, the preemption condition is also met. This prevents the second terminal from providing assistance to the side transmission service of the fourth terminal with a lower priority. At the same time, P A >P j >P p >P i 、P A >P p >P j >P i In these two non-preemptive situations, if the second auxiliary priority is higher than the second priority threshold, that is, P A Higher than P p Therefore, the second terminal can use the resources corresponding to the second auxiliary priority to assist the sideline transmission of the fourth terminal, that is, the second terminal has more candidate resources for sending auxiliary information to the fourth terminal.

[0174] Option 7: The lowest priority level among the second priority threshold and the first service priority level is higher than the lowest priority level among the second service priority level and the second auxiliary priority level; that is, this option can be expressed as min{P p ,P j}>min{P i , P A Please refer to option 7 in Table 5. In this option, P is added compared to option 1. A <P p <P i <Pj , P A <P j <P i <P p , P A <P j <P p <P i , P A <P p <P j <P i These four situations of preempting resources corresponding to the second auxiliary priority. i <P p And P i <P j Under the condition that the second auxiliary priority is the lowest compared with other priorities, the resources corresponding to the second auxiliary priority are preempted, thereby preventing the second terminal from providing assistance to the side transmission service of the fourth terminal with a lower priority.

[0175] Option 8: The highest priority among the second priority threshold and the first service priority is higher than the lowest priority among the second service priority and the second auxiliary priority; that is, this option can be expressed as max{P p ,P j}>min{P i ,P A The analysis of this option is similar to that of option seven and will not be repeated here.

[0176] Table 5

[0177]

[0178]

[0179] In step 2, corresponding to Figure 7 In the scenario shown, if the fifth condition is met, the first terminal preempts the resources corresponding to the second service priority. The fifth condition may be:

[0180] Option 1: The second service priority is lower than the second priority threshold and lower than the first service priority, or the second service priority is lower than the second priority threshold and the second service priority is equal to the first service priority and the first auxiliary priority is higher than the first priority threshold; that is, this option can be expressed as (P i <P p And P j >P i ) or (P i <P p And P i =P j And P D >PAS ). In this option, the second service priority is compared with the second priority threshold and the first service priority. If the second service priority is lower than the second priority threshold and the first service priority at the same time, the resources corresponding to the second service priority are seized. If the second service priority is lower than the second priority threshold and the second service priority is equal to the first service priority, the relationship between the first auxiliary priority and the first priority threshold is compared. If the first auxiliary priority is higher, the resources corresponding to the second service priority are seized. Therefore, the first terminal can use the resources corresponding to the second service priority to provide assistance to the side transmission service of the third terminal, that is, the first terminal has more candidate resources when sending auxiliary information to the third terminal.

[0181] Option 2: The second service priority is lower than the second priority threshold, and the first auxiliary priority is higher than the first priority threshold; that is, this option can be expressed as P i <P p And (P j >P i or P D >P AS For this option, please refer to the analysis of Option 1 and will not be repeated here.

[0182] Option 3: The second service priority is lower than the second priority threshold, and the first service priority is higher than the second service priority and the first auxiliary priority is higher than the first priority threshold; that is, this option can be expressed as P i <P p And (P j >P i And P D >P AS For this option, please refer to the analysis of Option 1 and will not be repeated here.

Compared to Option 1, this option adds the following: if the first service priority is lower than the second service priority, but the first auxiliary priority is higher than the second service priority, the resources corresponding to the second service priority will be preempted. Therefore, the first terminal can use the resources corresponding to the second service priority to assist the sidelink transmission service of the third terminal, that is, the first terminal has more candidate resources when sending auxiliary information to the third terminal.

[0184] Option 5: The second service priority is lower than the second priority threshold, and the lowest priority of the first service priority and the first auxiliary priority is higher than the second service priority; that is, this option can be expressed as P i <P p And min{P j ,P D}>P i Please refer to Option 5 in Table 6. Compared to Option 1, this option adds the following: if the first service priority is higher than the second service priority, but the first auxiliary priority is lower than the second service priority, the first terminal will not preempt the resources corresponding to the second service priority. Therefore, if the first auxiliary priority is lower, the first terminal will not provide assistance to the sidelink transmission service of the third terminal.

[0185] Table 6

[0186]

[0187]

[0188] Option 6: The highest priority among the second priority threshold, the first service priority and the first auxiliary priority is higher than the second service priority; that is, this option can be expressed as max{P p ,P j ,P D}>P i Please refer to Option 6 in Table 7. In this option, compared to Option 1, if the second priority threshold exists, or the first service priority or the first auxiliary priority is higher than the second service priority, the first terminal preempts the resources corresponding to the second service priority. Therefore, the first terminal can use the resources corresponding to the second service priority to assist the sidelink transmission service of the third terminal, that is, the first terminal has more candidate resources when sending auxiliary information to the third terminal.

[0189] Table 7

[0190]

[0191]

[0192] Option 7: The lowest priority among the second priority threshold, the first service priority, and the first auxiliary priority is higher than the second service priority; that is, this option can be expressed as min{P,P j ,P D}>P iPlease refer to Option 7 in Table 7. In this option, compared to Option 1, if the second service priority in Option 1 is lower than both the first service priority and the second preemption priority, and if the first auxiliary priority is lower than the second service priority, the first terminal does not preempt the resources corresponding to the second service priority. Therefore, if the first auxiliary priority is lower, the first terminal is prevented from providing assistance to the sidelink transmission service of the third terminal.

[0193] In step 2, corresponding to Figure 8 In the scenario shown, if the sixth condition is met, the first terminal preempts the resources corresponding to the second service priority. The sixth condition may be:

[0194] Option 1: The second service priority is lower than the second priority threshold and lower than the first service priority, or the second service priority is lower than the second priority threshold and the second service priority is equal to the first service priority and the first auxiliary priority is higher than the first priority threshold; that is, this option can be expressed as (P i <P p And P j >P i ) or (P i <P p And P i =P j And P D >P AS ). For this option, please refer to Figure 7 Option 1 in the scenario shown is not described here in detail.

[0195] Option 2: The second service priority is lower than the second priority threshold, and the first auxiliary priority is higher than the first priority threshold; that is, this option can be expressed as P i <P p And (P j >P i or P D >P AS ). For this option, please refer to Figure 7 Option 2 in the scenario shown is not described here in detail.

[0196] Option 3: The second service priority is lower than the second priority threshold, and the first service priority is higher than the second service priority and the first auxiliary priority is higher than the first priority threshold; that is, this option can be expressed as P i <P p And (P j >P i And P D >P AS ). For this option, please refer to Figure 7 Option 3 in the scenario shown is not described here in detail.

[0197] Option 4: The second service priority is lower than the second priority threshold and lower than the first service priority, or the second service priority is lower than the second priority threshold and the second service priority is equal to the first service priority and the first auxiliary priority is higher than the second auxiliary priority; that is, this option can be expressed as (P i <P p and P j >P i ) or (P i <P p and P i =P j and P D >P A ). Compared with Option 1 in this scenario, this option adds that if the first auxiliary priority is higher than the second auxiliary priority, the resources corresponding to the second auxiliary priority are preempted. Thus, it encourages the first terminal to provide assistance for the sidelink transmission service of the third terminal with a higher priority, that is, the third terminal can obtain more candidate resources.

[0198] Option 5: The second service priority is lower than the second priority threshold, and the highest priority among the first service priority and the first auxiliary priority is higher than the second service priority; that is, this option can be expressed as P<0, i <P p and max{P j ,P D}>P i . For this option, please refer to Option 4 in the scenario shown in Figure 7 , which will not be elaborated here.

[0199] Option 6: The second service priority is lower than the second priority threshold, and the lowest priority among the first service priority and the first auxiliary priority is higher than the second service priority; that is, this option can be expressed as P i <Pp and min{P j ,P D}>P i . For this option, please refer to Option 5 in the scenario shown in Figure 7 , which will not be elaborated here.

[0200] Option 7: The highest priority among the second priority threshold, the first service priority and the first auxiliary priority is higher than the second service priority; that is, this option can be expressed as max{P p ,P j ,P D}>P i . For this option, please refer to Option 6 in the scenario shown in Figure 7 , which will not be elaborated here.

[0201] Option 8: The lowest priority among the second priority threshold, the first service priority and the first auxiliary priority is higher than the second service priority; that is, this option can be expressed as min{P p ,P j ,P D}>P i For this option, please refer to Figure 7 Option 7 in the scenario shown is not described here in detail.

[0202] Option 9: The second service priority is lower than the second priority threshold, and the highest priority of the first service priority and the first auxiliary priority is higher than the highest priority of the second service priority and the second auxiliary priority; that is, this option can be expressed as P i <P p And max{P j ,P D}>max{P i ,P A In this option, relative to option 1 of this scenario, if P in option 1 is satisfied i <P p And P i <P j Under the condition that the first auxiliary priority is higher than both the second service priority and the second auxiliary priority, the first terminal preempts the resources corresponding to the second service priority or the second auxiliary service priority. Therefore, the first terminal can use the resources corresponding to the second service priority to assist the sidelink transmission service of the third terminal, that is, the first terminal has more candidate resources when sending auxiliary information to the third terminal.

[0203] Option 10: The second service priority is lower than the second priority threshold, and the lowest priority of the first service priority and the first auxiliary priority is higher than the highest priority of the second service priority and the second auxiliary priority; that is, this option can be expressed as P i <P p And min{P j ,P D}>max{P i ,P A The analysis of this option is similar to that of option 9 and will not be repeated here.

[0204] Option 11: The second service priority is lower than the second priority threshold, and the highest priority of the first service priority and the first auxiliary priority is higher than the lowest priority of the second service priority and the second auxiliary priority; that is, this option can be expressed as P i <P p And max{P j ,P D}>min{P i,P A The analysis of this option is similar to that of option 9 and will not be repeated here.

[0205] Option 12: The second service priority is lower than the second priority threshold, and the lowest priority of the first service priority and the first auxiliary priority is higher than the lowest priority of the second service priority and the second auxiliary priority; that is, this option can be expressed as P i <P p And min{P j ,P D}>min{P i ,P A The analysis of this option is similar to that of option 9 and will not be repeated here.

[0206] It is worth noting that in scenario two or scenario three, the process in which the first terminal assists the third terminal based on the first information and the second information to determine the candidate resources for the side transmission of the third terminal can be based on the first condition and / or the fourth condition for the first terminal to determine the candidate resources for side transmission in scenario one. If the first condition is met, the first terminal excludes the resources corresponding to the second business priority or the second auxiliary priority from the candidate resources of the first terminal. If the fourth condition is met, the first terminal seizes the resources corresponding to the second business priority or the second auxiliary priority. Thus, the third terminal can exclude the resources corresponding to the second auxiliary priority or the second business priority of a higher level; or, the third terminal can occupy the resources corresponding to the second auxiliary priority or the second business priority of a lower level. Thus, the third terminal is prevented from excluding the resources corresponding to the second auxiliary priority or the second business priority of a lower level; or, the third terminal is prevented from occupying the resources corresponding to the second auxiliary priority or the second business priority of a higher level.

[0207] based on Figure 3-Figure 8 In the resource configuration method shown in any one of the items, the first terminal determines, based on the first service priority and / or the first auxiliary priority, and the second service priority and / or the second auxiliary priority, the candidate resources for sideline transmission by the first terminal, and / or the candidate resources for sideline transmission by the first terminal assisting a third terminal. Thus, when the first terminal assists the third terminal with a higher-priority sideline transmission, the first terminal can obtain more candidate resources when sending assistant information (ASI); or, when the second terminal assists the fourth terminal with a higher-priority sideline transmission, the second terminal can obtain more candidate resources when sending assistant information; and the interference of the assistant terminal on normal sideline transmission is reduced.

[0208] Figure 9A communication diagram of another resource configuration method provided in an embodiment of the present application, in which the second terminal can provide assistance to multiple fourth terminals, and the method flow for determining the candidate resources for side transmission for the fourth terminal is as follows: Figure 10 As shown, the specific steps are as follows:

[0209] S1001, the fourth terminal obtains the fourth service priority and the second auxiliary priority. Among them, the fourth service priority is the physical layer priority of the fourth terminal, that is, the priority corresponding to the PSSCH when the fourth terminal sends a data transmission packet. The second auxiliary priority is the priority that the second terminal assists the fourth terminal in selecting side transmission resources. The fourth terminal determines the candidate resources for side transmission of the fourth terminal based on the fourth service priority and the second auxiliary priority. It should be noted that the second auxiliary priority can be the priority of the second terminal to assist the fourth terminal in selecting candidate resources for side transmission, or it can be the priority carried by the fourth terminal when sending an auxiliary request to the second terminal for assisting the second terminal in selecting resources for SL communication transmission.

[0210] It should be noted that the fourth service priority and the second auxiliary priority are both carried by sidelink control information (SCI).

[0211] S1002: The fourth terminal determines candidate resources for sidelink transmission of the fourth terminal according to the fourth service priority and the second auxiliary priority.

[0212] In step S1002, an optional approach is that if the fourth service priority is higher than or equal to the second auxiliary priority, the fourth terminal uses the resources corresponding to the second auxiliary priority as candidate resources for sidelink transmission by the fourth terminal.

[0213] It should be understood that Figure 9 、 Figure 10 In the resource configuration method shown in , the third terminal may also obtain a third service priority and a first auxiliary priority. The third service priority is the physical layer priority of the third terminal, and the first auxiliary priority is the priority that the first terminal uses to assist the third terminal in selecting sidelink transmission resources. The third terminal determines candidate resources for sidelink transmission based on the third service priority and the first auxiliary priority. The specific determination method is described in step S1002 and will not be further described here.

[0214] based on Figure 9-10In the resource configuration method shown in any one of the items, the fourth terminal determines the candidate resources for side transmission of the fourth terminal based on the obtained fourth service priority and the second auxiliary priority, or the third terminal determines the candidate resources for side transmission of the third terminal based on the obtained third service priority and the first auxiliary priority, and clarifies which terminals can use the auxiliary resources provided by the auxiliary terminal. Taking the second terminal assisting the fourth terminal as an example, when the fourth terminal has a lower level of service priority, that is, the fourth service priority is low, the second terminal will provide fewer candidate resources to the fourth terminal, and even the candidate resources cannot be used by the fourth terminal; on the contrary, when the fourth terminal has a higher level of service priority, that is, the fourth service priority is high, the second terminal will provide more candidate resources to the fourth terminal, so that the fourth terminal can obtain more candidate resources.

[0215] Of course, in the above Figure 9-10 In the provided resource configuration method, the second terminal may provide assistance to one or more fourth terminals, and the fourth terminal may also be assisted by one or more second terminals.

[0216] This application embodiment provides a resource configuration device, please refer to Figure 11 , is a structural diagram of a resource configuration device provided in an embodiment of the present application, wherein the resource configuration device includes an acquisition module 1101 and a determination module 1102.

[0217] In some embodiments, the resource configuration device 1100 may be applicable to Figure 1 In the communication system shown in FIG, execution Figure 5 The function of the first terminal in the resource configuration method shown in .

[0218] Among them, the acquisition module 1101 is used to obtain first information and second information; the first information includes a first service priority and / or a first auxiliary priority; the first service priority is the physical layer priority of the device 1100, and the first auxiliary priority is the priority of the device 1100 to assist the third terminal in selecting side transmission resources; the second information includes a second service priority and / or a second auxiliary priority; the second service priority is the physical layer priority of the second terminal; the second auxiliary information is the priority of the second terminal to assist the fourth terminal in selecting side transmission resources.

[0219] The determination module 1102 is configured to determine candidate resources of the apparatus 1100 based on the first information and the second information; wherein the candidate resources of the apparatus 1100 are used for sideline transmission of the apparatus 1100 or for sideline transmission of the apparatus 1100 to assist a third terminal.

[0220] In one possible design, the determination module includes an exclusion module and / or a preemption module. The exclusion module is configured to exclude resources corresponding to the second service priority from candidate resources of apparatus 1100 based on the first information and the second information.
