Description

Technical Field

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

[0002] At present, in vehicle to vehicle (V2V) and vehicle to everything (V2X) communication scenarios using sidelink (SL) transmission (or side transmission) technology, considering the power consumption problem, user equipment (UE) performing SL communication often adopts different resource acquisition methods. For example, some UEs can actively select the resources used for side transmission, while some UEs cannot actively select the resources used for side transmission.

[0003] In order to meet the requirements of different types of UEs for side-line transmission, it is necessary to refine and improve the method of UEs to determine the resources used for side-line transmission. Summary of the invention

[0004] The present application provides a resource determination method and device to meet the requirements of different types of UEs for side-line transmission.

[0005] In a first aspect, an embodiment of the present application provides a resource determination method, which can be executed by a first communication device or by a component of the first communication device (such as a processor, a chip or a chip system, etc.). The first communication device can be a UE supporting sideline transmission.

[0006] The following description is made by taking the execution subject as the first communication device as an example. According to the method, the first communication device can obtain the first resource information and determine the transmission resource according to the type of the first communication device and the first resource information. The first communication device transmits the side transmission data through the transmission resource transmission. Among them, the first resource information can be used to indicate the first category of resources and / or the second category of resources. The first category of resources refers to resources whose signal strength is not less than (or greater than) the first threshold or whose occupancy rate is not less than (or greater than) the second threshold. The second category of resources refers to resources whose signal strength is not greater than (or less than) the third threshold or whose occupancy rate is not greater than (or less than) the fourth threshold.

[0007] By adopting the above method, the first communication device can determine the transmission resource according to the type of the first communication device and the resource indicated by the first resource information, and perform side transmission through the transmission resource. Since the first resource information can indicate high-interference or high-occupancy resources (that is, not recommended resources), the first communication device can consider avoiding these resources to select transmission resources, and the first resource information can also indicate low-interference or low-occupancy resources (that is, recommended resources), the first communication device can consider selecting these resources, so that the first communication device can select low-interference resources for side transmission according to its own type, thereby improving the side transmission performance.

[0008] In one possible design, the first communication device may receive the first resource information from the third communication device. The third communication device may be a network device (such as a base station) or a user device (such as a head UE, a roadside processing unit, etc.). The first resource information may be sent to the first communication device during the process of the first communication device initially accessing the third communication device. The access here may be the process of UE accessing a network device, the process of a member UE accessing a head UE, or the process of UE accessing a roadside processing unit. With this design, the third communication device may obtain the first resource information from the third communication device, implement the configuration and management of the resource information by the third communication device, avoid resource conflicts caused by the UE's self-selection of resources, and further reduce the interference to the first communication device in side transmission.

[0009] Among them, the first resource information is related to the position of the first communication device. Specifically, the first resource information is determined based on the location information of the first communication device.

[0010] In one possible design, the type of the first communication device is an unaware type, a partially aware type, or a fully aware type. For example, an unaware type UE does not perceive data transmitted by surrounding UEs, and a partially aware type UE can perceive data transmitted by some surrounding UEs. Such UEs can reduce resource conflicts for data transmission and further improve transmission performance by receiving the first resource information sent by the base station. Therefore, different methods can be used to determine transmission resources for different types of UEs to reduce interference to different types of UEs performing side transmissions.

[0011] In one possible design, the first resource information may come from the second communication device. The first communication device may determine the transmission resource based on the first resource information, and send the side transmission data to the second communication device based on the transmission resource. With this design, the interference received when the first communication device sends the side transmission data to the second communication device can be further reduced, thereby improving the transmission performance.

[0012] In one possible design, if the first communication device determines that its type is an unaware type, the first communication device may select transmission resources based on resources other than the first type of resources or the second type of resources. For example, resources other than the first type of resources or the second type of resources are used as transmission resources. In this way, even if the type of the first communication device is an unaware type, or in other words, the first communication device is not required to have perception capabilities, the first communication device obtains recommended resources from a third communication device (such as a network device) to avoid resource congestion.

[0013] In a possible design, if the first communication device determines that its type is a partially perceived type or a fully perceived type, the first communication device may determine a resource pool and select transmission resources from resources other than the first type of resources or the second type of resources in the resource pool. The resources in the resource pool are used for side transmission by the first communication device. For example, resources other than the first type of resources or the second type of resources in the resource pool are used as transmission resources. In this way, the partially perceived UE can obtain recommended resources from the network device, thereby avoiding the resource congestion problem of the partially perceived UE within the time range outside the perception window. At the same time, the resource information indicated by the third communication device (such as the network device) can also enable the partially perceived UE to better select the transmission resource, which can further reduce the interference to the side transmission of the first communication device. In addition, in this scheme, the resource information is indicated by the third communication device (such as the network device), so that the first communication device of the fully perceived type can better select the transmission resource, or the first communication device of the fully perceived type can appropriately reduce the perception of resources, and determine the transmission resource according to the resource information indicated by the third communication device, thereby saving power consumption while avoiding the resource congestion problem.

[0014] In one possible design, if the first communication device determines that its own type is a partial perception type or a full perception type, and the first resource information indicates a second type of resource, the first communication device can perceive the second type of resource, obtain the signal strength or occupancy rate of the second type of resource, and determine the transmission resource from the second type of resource based on the perception result. For example, based on the signal strength or occupancy rate of each second type of resource among multiple second type resources, select the resource with the smallest signal strength or the lowest occupancy rate as the transmission resource. In this way, the first communication device can select a transmission resource from the second type of resource based on the first resource information and the perception result obtained by itself, further reducing the interference received when the selected transmission resource sends data on the side.

[0015] In one possible design, if the first communication device determines that its own type is a partial perception type or a full perception type, and the first resource information indicates a first category of resources, the first communication device can perceive the signal strength or occupancy rate of resources other than the first resource, and determine the transmission resource from the resources other than the first resource based on the perception result. The resources other than the first resource may be resources other than the first resource in the resource pool. For example, based on the signal strength or occupancy rate of each resource among multiple resources other than the first category of resources, the resource with the smallest signal strength or the lowest occupancy rate is selected as the transmission resource. In this way, the first communication device can select a transmission resource from resources other than the first category of resources based on the first resource information and the perception results obtained by itself, further reducing the interference received when the selected transmission resource sends data on the side. In addition, this method does not require the perception of the first category of resources, thereby reducing power consumption.

[0016] In a possible design, if the first communication device determines that its own type is a partially sensed type or a fully sensed type, and the first resource information indicates a first type of resource, the first communication device may obtain resources in the resource pool of the first communication device, and the resources in the resource pool of the first communication device include the first type of resources. The first communication device may also sense the signal strength of the resources in the resource pool of the first communication device and the priority of the data transmitted by the resources. Thereafter, the first communication device may determine the first signal strength threshold of the first type of resources according to the priority of the side transmission data and the priority of the data transmitted by the first type of resources. The first communication device also determines the second signal strength threshold of the first type of resources according to the first resource information, and the second signal strength threshold is less than the first signal strength threshold of the first type of resources. The first communication device may further determine whether to use the first type of resource as a candidate resource according to the second signal strength threshold and the signal strength of the first type of resource, and the candidate resource is used to determine the transmission resource. The first communication device may subsequently determine the transmission resource from the candidate resources. With this design, the first communication device can select a transmission resource based on the perception result, wherein the non-recommended resource indicated by the first resource information is more difficult to be determined as a transmission resource, so as to reduce the interference received by the first communication device during the side transmission process. In addition, with this method, the transmission resource finally selected can still be the first type of resource indicated by the first resource information, so the possibility of side transmission of data through the first type of resource is not excluded, so as to improve the transmission success rate. In addition, the first communication device no longer perceives the first type of resource, which can reduce power consumption.

[0017] In a possible design, if the first communication device determines that its type is a partially sensed type or a fully sensed type, and the first resource information indicates a second type of resource, the first communication device may obtain resources in the resource pool of the first communication device, and the resources in the resource pool of the first communication device include the second type of resource. Thereafter, the first communication device may sense the signal strength of the resources in the resource pool of the first communication device and the priority of the data transmitted by the resources, and determine the first signal strength threshold of the second type of resource according to the priority of the side transmission data and the priority of the data transmitted by the perceived second type of resource. Thereafter, the first communication device determines the second signal strength threshold of the second type of resource according to the first resource information, and the second signal strength threshold is less than the first signal strength threshold of the second type of resource. Further, the first communication device may determine whether to use the second type of resource as a candidate resource according to the second signal strength threshold and the signal strength of the second type of resource, and the candidate resource is used to determine the transmission resource. The first communication device may subsequently determine the transmission resource from the candidate resources. In this way, the first communication device can select transmission resources based on the perception results of each resource in the resource pool and the recommended resources indicated by the first resource information, wherein the conditions for the recommended resources indicated by the first resource information to be selected as transmission resources are relaxed. In other words, the recommended resources indicated by the first resource information are more likely to be selected as resources to reduce interference received by the first communication device during side transmission.

[0018] In a possible design, if the first communication device determines that its type is a partial perception type or a full perception type, and the first resource information indicates a first type of resource and a second type of resource, the first communication device can obtain resources in the resource pool of the first communication device, and the resources in the resource pool of the first communication device include the first type of resource and the second type of resource. The first communication device can also perceive the signal strength of the resources in the resource pool of the first communication device and the priority of the data transmitted by the resources, and determine the first signal strength threshold of the first type of resources according to the priority of the side transmission data and the priority of the data transmitted by the first type of resources, and determine the first signal strength threshold of the second type of resources according to the priority of the side transmission data and the priority of the data transmitted by the second type of resources. Thereafter, according to the first resource information, the first communication device can determine the second signal strength threshold of the first type of resources and the second signal strength threshold of the second type of resources, wherein the second signal strength threshold of the first type of resources is less than the first signal strength threshold of the first type of resources, and the second signal strength threshold of the second type of resources is less than the second signal strength threshold of the second type of resources. Further, the first communication device may determine whether to use the first type of resource as a candidate resource based on the second signal strength threshold of the first type of resource and the signal strength of the first type of resource, and determine whether to use the second type of resource as a candidate resource based on the second signal strength threshold of the second type of resource and the signal strength of the second type of resource, and the candidate resource is used to determine the transmission resource. Thereafter, the first communication device may determine the transmission resource from all band selections.

[0019] In this way, the transmission resource can be selected according to the perception result of each resource in the resource pool in combination with the recommended resource and the non-recommended resource indicated by the first resource information, wherein the condition for the recommended resource indicated by the first resource information to be selected as the transmission resource is relaxed, and the condition for the non-recommended resource to be selected as the transmission resource is narrowed, so as to reduce the interference received by the first communication device during the side transmission process. In addition, in this way, the transmission resource finally selected can still be the first type of resource indicated by the first resource information.

[0020] In a possible design, if the first communication device determines that its type is a partial perception type or a full perception type, and the first resource information indicates the first type of resources and the second type of resources, the first communication device can obtain resources other than the first type of resources in the resource pool of the first communication device, and the resources other than the first type of resources in the resource pool include the second type of resources. The first communication device can perceive the signal strength of resources other than the first type of resources and the priority of data transmitted by the resources in the resource pool, and determine the first signal strength threshold of the second type of resources according to the priority of the side transmission data and the priority of the data transmitted by the second type of resources. Thereafter, the first communication device can determine the second signal strength threshold of the second type of resources according to the first resource information, and the second signal strength threshold is less than the first signal strength threshold of the second type of resources. The first communication device can also determine whether to use the second type of resources as a candidate resource based on the second signal strength threshold and the signal strength of the second type of resources, and the candidate resource is used to determine the transmission resource. Thereafter, the first communication device can determine the transmission resource from the candidate resources.

[0021] In this way, according to the first resource information, the perception result of each resource other than the first resource in the resource pool can be combined with the recommended resource indicated by the first resource information, and the transmission resource can be selected from the resources other than the first resource in the resource pool, wherein the condition for the recommended resource indicated by the first resource information to be selected as the transmission resource is relaxed, and the non-recommended resource will not be selected as the transmission resource, so as to reduce the interference received by the first communication device during the side transmission process. In addition, in this way, the first communication device no longer needs to perceive the first type of resources, so as to save power consumption.

[0022] In a second aspect, the present application provides a resource determination method. The method may be performed by a third communication device, or may be performed by a component of the third communication device (such as a processor, a chip, or a chip system, etc.). The third communication device may be a base station, such as a gNB.

[0023] The following description is made by taking the execution subject as the third communication device as an example. According to the method, the third communication device can determine the first category of resources and / or the second category of resources based on the location information of the first communication device. Furthermore, the third communication device can send first resource information to the first communication device, and the first resource information is used to indicate the first category of resources and / or the second category of resources. Among them, the signal strength of the first category of resources is not less than (or greater than) the first threshold, and / or the occupancy rate of the first category of resources is not less than (or greater than) the second threshold. The signal strength of the second category of resources is not greater than (or less than) the third threshold, and / or the occupancy rate of the second category of resources is not greater than (or less than) the fourth threshold.

[0024] By using the above method, the third communication device can indicate the first resource information to the first communication device, so that the first communication device can avoid the first type of resources and select transmission resources or select transmission resources from the second type of resources according to the first resource information to improve the performance of the first communication device in side transmission.

[0025] In one possible design, the third communication device may obtain the first correspondence, and determine the first type of resources and / or the second type of resources corresponding to the location information of the first communication device based on the first correspondence and the location information of the first communication device, wherein the first correspondence includes the correspondence between the location information and the first type of resources or the second type of resources. The third communication device obtaining the first correspondence may include the third communication device obtaining the first correspondence stored in the memory, or the third communication device receiving the first correspondence from other communication devices (such as other base stations other than the third communication device). With this design, the efficiency of determining the resources related to the first communication device can be improved.

[0026] In one possible design, the third communication device may obtain the first information from the fourth communication device, and obtain the location information of the fourth communication device. The fourth communication device may be a user equipment of a partial perception type or a full perception type within the coverage of the third communication device. The first information is used to indicate the first category of resources and / or the second category of resources determined by the fourth communication device. The third communication device may determine a first corresponding relationship based on the first category of resources or the second category of resources determined by the fourth communication device and the location information of the fourth communication device, so as to provide a more accurate resource indication.

[0027] In one possible design, the above first information may be sent during the process of the fourth communication device initially accessing the third communication device, or may be sent according to the first cycle, or the third communication device may send the second information to the fourth communication device to request the first information to improve the timeliness of the first resource information.

[0028] In one possible design, the above first resource information may be sent during the process of the first communication device initially accessing the third communication device, or may be sent according to the second period, or may be sent after the third communication device determines that the location information of the first communication device has changed, or the third communication device may send the first resource information in response to third information from the first communication device, wherein the third information can be used to request the first resource information to improve the timeliness of the first resource information.

[0045] In order to make the purpose, technical solution and advantages of the present application more clear, the present application will be further described in detail below in conjunction with the accompanying drawings. The specific operation method in the method embodiment can also be applied to the device embodiment or the system embodiment.

[0046] The resource determination method provided by the embodiments of the present application can be applied to Figure 1 Communication scenario shown. Figure 1 The communication device in the side-line transmission scenario is shown. Specifically, the communication device may include user equipment and network equipment, for example, Figure 1 The first communication device and / or the second communication device shown may be a user equipment and the third communication device may be a network equipment.

[0047] like Figure 1As shown, the wireless communication system 100 provided in the embodiment of the present application includes a first communication device, a second communication device and a third communication device. The application scenarios of the wireless communication system 100 include but are not limited to the long-term evolution (LTE) system, the future fifth generation (5G) system, the new radio (NR) communication system, the NR vehicle networking system or the future vehicle networking system based on mobile communication. It should be understood that the wireless communication system 100 provided in the embodiment of the present application can be applied to both low-frequency scenarios (sub 6G) and high-frequency scenarios (above 6G).

[0048] Exemplarily, the first communication device and / or the second communication device may be a terminal, a mobile station (MS), a mobile terminal, or a chip, a chip system, or other devices. The first communication device and / or the second communication device can communicate with one or more network devices of one or more communication systems, and accept network services provided by the network devices, where the network devices include but are not limited to the third communication device shown in the figure. For example, the first communication device and / or the second communication device in the embodiment of the present application may be a mobile phone (or a "cellular" phone), a computer with a mobile terminal, an intelligent vehicle, a vehicle-related intelligent device (such as an intelligent street lamp, etc.), a wearable device, etc. The first communication device and / or the second communication device may also be a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device. The first communication device and the second communication device may also be a communication chip with a communication module. It should be understood that the first communication device and / or the second communication device may be configured to support communication with network devices including the third communication device through a universal user to network interface (Uu air interface) of the network. In addition, the first communication device and the second communication device may be configured to support sidelink transmission, for example, the first communication device and the second communication device may perform sidelink communication via a direct communication (PC5) air interface. The first communication device and / or the second communication device may be a chip having a communication module or connectable to a communication module, such as a chip in a vehicle-mounted device.

[0049] The third communication device may include a network device. The network device may include a base station (BS), or a base station and a wireless resource management device for controlling the base station. The base station here may be an evolutionary node B (eNB or eNodeB), a small base station (micro / picoeNB) or a transmission / reception point (TRP) in an LTE system, or a wireless controller in a cloud radio access network (CRAN) scenario. Alternatively, the third communication device may be a relay station, an access point, a wearable device, a base station in a future 5G network, or a base station in a future evolved PLMN network, for example, a new generation node B (generated node B, gNB), which is not limited in the embodiments of the present application. The third communication device may also be a chip having a communication module or connectable to a communication module, such as a chip in a base station.

[0050] It should be understood that in the present application, the third communication device may support Uu interface communication, for example, to support access of the first communication device through the Uu interface.

[0051] In addition, the third communication device may also include a user equipment. For example, the third communication device may include a head UE (or platform UE) in a group communication scenario, and the head UE can be used to manage one or more member UEs (such as the first communication device) accessing the head UE. The head UE and one or more member UEs can perform group communication. For example, the head UE can send road information and group management information to the member UE. In addition, the third communication device may also be a roadside processing unit (or roadside processing UE), such as a user equipment in the form of a smart street light, an intersection management unit, and the like. The roadside processing unit can manage the UE (such as the first communication device) accessing the roadside processing unit, for example, by sending some road information and management information to these UEs. In this example, the third communication device can perform SL communication with the first communication device.

[0052] based on Figure 1 In the architecture shown, the third communication device can be used to configure SL data transmission between the first communication device and the second communication device. For example, the third communication device can perform SL authorization (SL grant) to the first communication device and the second communication device via the Uu air interface, and configure a resource pool to the first communication device and the second communication device respectively, for SL data transmission between the first communication device and the second communication device using resources in the resource pool.

[0053] Taking the third communication device as a network device (such as gNB) as an example, an application scenario of the wireless communication system 100 provided by the embodiment of the present application is as follows: Figure 2shown.

[0054] Figure 2 The dotted ellipse line is a schematic coverage range of the network device. For example, if the third communication device is a network device, the dotted line may represent the range of one or more cells of the network device. It can be seen that in the V2X scenario, there may be multiple types of user devices within the coverage range of a network device, and these user devices include but are not limited to the first communication device and the second communication device. Exemplarily, these user devices are types such as vehicle terminals (vehicle user / vehicle UE, VUE) and vulnerable roadside equipment (vulnerable road user / unit, VRU), among which VRU may include person terminals (person user / person UE, PUE) and road side units (road side unit, RSU), smart street lights, etc. These UEs can be divided into full-sensing type, partial-sensing type or no-sensing type according to the different power sustainability and real-time communication requirements.

[0055] Among them, the unaware UE does not perceive the data sent by other UEs, that is, the unaware UE cannot obtain the channel used by other UEs for transmission based on the data sent by other UEs. The unaware UE can randomly select resources from the configured resource pool for transmission, which may conflict with the transmission resources used by other UEs for transmission, interfering with the transmission of other UEs and also interfering with its own transmission.

[0056] Partial perception type means that the UE can perceive in a shorter time window (which can be called a perception window), that is, receive data transmitted by other UEs in a shorter time window, and obtain the priority of other UE transmission data and resource information used for data transmission based on the data. Therefore, within the perception window, the UE of partial perception type can know the resources used by nearby UEs, avoid data transmission on resources where data transmission is perceived, and reduce transmission interference to a certain extent. However, in the time period outside the perception window, transmission interference cannot be reduced, so the UE can only achieve low-interference transmission in a shorter window, and the transmission performance is limited.

[0057] The full perception type means that the UE can continuously receive data transmitted by other UEs, and the time window for receiving data covers the entire range of the service cycle. Therefore, the UE can more accurately know the resources used by nearby UEs based on the received data, and can avoid data transmission on resources where data transmission is perceived.

[0058] Exemplarily, vehicle to infrastructure (V2I) communication can be realized between RSU and VUE or PUE. For example, RSU can be used to notify VUE and PUE of traffic conditions and the like. V2V communication can be realized between VUE (or PUE) and VUE (or PUE). Among them, VUE is generally deployed on a vehicle, for example, it can be a vehicle-mounted device or other terminal device deployed in a vehicle. PUE can be a UE carried by pedestrians, such as a mobile device such as a mobile phone. RSU is generally deployed on one side or both sides of the road.

[0059] At present, in order to save the cost of receiving circuits, PUE and VRU may adopt the non-perception type. In addition, for PUE and VRU that cannot obtain electricity continuously due to solar power or battery power, they are not like VUE that can obtain electricity continuously from vehicles, so they need to use partial perception schemes to save energy and extend the service life of the equipment. For fully-perception type UEs, such as VUEs, it is necessary to receive data transmitted by surrounding UEs on all subframes or all resources. These data can be used by UEs to know the locations of other UEs and the resources used by other UEs for data transmission. For partially-perception type UEs, they only need to receive data transmitted by surrounding UEs on some subframes or some resources to know the locations of other UEs and the resources used by other UEs for data transmission. For non-perception type UEs, they do not receive data transmitted by surrounding UEs.

[0060] also, Figure 2 The VUE shown is generally an on-board device such as an on-board communication unit. It can be considered that the VUE can obtain power from the vehicle and does not need to adopt the perception capability of non-perception or partial perception to reduce power consumption. Therefore, the VUE is generally a perception type, that is, it continuously receives data transmitted by surrounding terminals during the service cycle. In addition, the VRU connected to the power supply can also adopt full perception. Compared with the non-perception type or partial perception type UE, the full perception type UE can obtain all data sent by other surrounding UEs during the service cycle, so it can know the interference of surrounding resources and the location of nearby UEs.

[0061] Since the current V2X service is a periodic service, UEs of partial perception type or full perception type can obtain the complete interference situation of resources in the service cycle based on the perception results in the previous service cycle, and find resources with lower interference in the service cycle (such as finding resources with interference not greater than or less than a certain threshold), so as to select these resources in the next service cycle, and transmit through resources with lower interference. Specifically, the perception result can be reflected in the signal strength of the received signal of other UEs on the resource perceived by the UE (hereinafter referred to as the signal strength of the resource) or in information such as the occupancy rate of the resource. For example, when the UE perceives that the signal strength of resource X is relatively large, it means that other UEs are transmitting data on resource X. If the UE still uses resource X for side transmission, it will be subject to greater signal interference.

[0062] For example Figure 3 As shown in the figure, compared with the full-sensing type UE, the partial-sensing type UE only senses in a smaller sensing window to obtain the resources used by other UEs to transmit data. Therefore, compared with the full-sensing type UE, the partial-sensing type UE can only select low-interference transmission resources in a smaller time period; if data is transmitted in other time periods outside the sensing window, the partial-sensing type UE cannot select low-interference transmission resources. In addition, the non-sensing type UE does not sense resources, so it cannot select low-interference transmission resources for side transmission.

[0063] Based on the above content, it can be known that there are differences in the way different types of UEs currently select resources for sidelink transmission. In some cases, UEs will still select high-interference or high-occupancy resources for transmission, resulting in low quality of sidelink transmission. Therefore, the current process of determining sidelink transmission resources still needs to be optimized. In order to optimize the resource selection process of the sidelink so that the performance of the sidelink transmission meets the transmission requirements of different types of UEs, an embodiment of the present application provides a resource determination method.

[0064] This method can be Figure 1 The first communication device and the third communication device shown are implemented. Exemplarily, the first communication device and the second communication device can be UE or a chip in the UE, and side transmission can be performed between the first communication device and the second communication device. The first communication device accesses the third communication device. The third communication device can be a network device such as a base station, or a UE such as a head UE or a roadside processing unit in a group communication scenario, or a chip in a network device or UE. In addition, the method can also be executed by the second communication device. Specifically, the first communication device is located within the coverage range of the third communication device, and the second communication device can be a user equipment within or outside the coverage range of the third communication device.

[0065] The method can be specifically applied to a scenario where a first communication device performs side transmission to a second communication device (or other communication devices). For example, in a scenario where a first communication device sends traffic information, location information, or other data to a second communication device via side transmission, the first communication device can determine the transmission resources used for the side transmission according to the resource determination method provided in the embodiment of the present application.

[0066] like Figure 4 As shown, the resource determination method provided by the embodiment of the present application may include the following steps:

[0067] S101: The first communication device acquires the first resource information.

[0068] The first resource information is used to indicate resources related to the first communication device. The resources related to the first communication device may include first-category resources and / or second-category resources. Among them, the first-category resources may include one or more resources, each of which satisfies: the signal strength (in decibels (dB)) is not less than (or greater than) the first threshold, the occupancy rate is not less than (or greater than) the second threshold, or the signal strength is not less than (or greater than) the first threshold and the occupancy rate is not less than (or greater than) the second threshold. In other words, the above first-category resources may include high-interference resources and / or high-occupancy resources. Therefore, if the first communication device performs data transmission on the first-category resources, it will be subject to greater transmission interference.

[0069] The second type of resources may include one or more resources, each of which satisfies: the signal strength is not greater than (or less than) the third threshold, the occupancy rate is not greater than (or less than) the fourth threshold, or the signal strength is not greater than (or less than) the third threshold and the occupancy rate is not greater than (or less than) the fourth threshold. The above second type of resources may include low interference resources and / or low occupancy resources, so if the first communication device transmits data on the second type of resources, the transmission interference is small.

[0070] In addition, the first type of resources may also be called a non-recommended resource, and the second type of resources may also be called a recommended resource.

[0071] The signal strength of the above-mentioned first and second category resources may refer to the signal strength of the received signal on the resource obtained by a UE with perception capability (including a partial perception type or a full perception type UE) sensing the resource. The greater the signal strength, the stronger the interference to the first communication device when performing side transmission on the resource.

[0072] Exemplary, the above first type of resources and / or second type of resources may be included in a resource pool for the first communication device. The resource pool may be configured by a network device (such as a third communication device).

[0073] The first resource information may carry information about the first category of resources, including the index, time domain and frequency domain location information of the first category of resources; the first resource information may carry information about the second category of resources, including the index, time domain and frequency domain location information of the second category of resources; or, the first resource information may also carry relevant information about the first category of resources and the second resources at the same time.

[0074] S102: The first communication device determines the transmission resource based on its own type and the first resource information.

[0075] The type of the first communication device is an unaware type, a partially aware type, or a fully aware type. Alternatively, the type of the first communication device is determined according to the awareness capability configuration of the first communication device.

[0076] Specifically, if the first resource information indicates non-recommended resources such as the aforementioned first category of resources (i.e., high-interference resources or high-occupancy resources), the first communication device will choose not to use the first category of resources and select other resources for side transmission; if the first resource information indicates recommended resources such as the aforementioned second category of resources (i.e., high-interference resources or high-occupancy resources), the first communication device will select resources from the second category of resources for side transmission.

[0077] Exemplarily, if the type of the first communication device is an unaware type, and the first resource information is used to indicate a first type of resource, the first communication device may perform side transmission from other resources other than the first type of resource (the other resources are, for example, transmission resources other than the first resource in the resource pool). If the type of the first communication device is an unaware type, and the first resource information is used to indicate a second type of resource, the first communication device may select a resource from the second type of resource for side transmission.

[0078] In addition, if the type of the first communication device is a partial perception type or a full perception type, and the first resource information is used to indicate the first type of resources, the first communication device may select resources for side transmission based on the perception results of all resources in the resource pool or the perception results of transmission resources other than the first type of resources in the resource pool. If the type of the first communication device is a partial perception type or a full perception type, and the first resource information is used to indicate the second type of resources, the first communication device may select resources for side transmission based on the perception results of all resources in the resource pool or the perception results of the second type of resources. If the type of the first communication device is a partial perception type or a full perception type, and the first resource information is used to indicate the first type of resources and the second type of resources, the first communication device may select resources for side transmission based on the perception results of all resources in the resource pool, the perception results of resources other than the first type of resources in the resource pool, or the perception results of the second type of resources.

[0079] S103: The first communication device transmits side-line transmission data through the transmission resource.

[0080] Exemplary, the first communication device may transmit data side-line transmission data through the transmission resource. For example, the first communication device Figure 1 The second communication device shown transmits side-line transmission data.

[0081] By adopting the above method, the first communication device can determine the transmission resource according to its own type and the first resource information. Since the first resource information can indicate the recommended resource or the non-recommended resource, the first communication device can avoid the non-recommended resource to select the transmission resource, and / or the first communication device can select the recommended resource as the transmission resource. Therefore, the first communication device can select the resource with lower interference for the side transmission, so as to reduce the interference of the side transmission and improve the transmission performance.

[0082] In one implementation mode of S101, the first communication device may Figure 1 The third communication device shown acquires the first resource information.

[0083] Exemplarily, the third communication device may determine resources related to the first communication device according to the location information of the first communication device, and send first resource information to the first communication device to indicate the resources related to the first communication device.

[0084] The location information of the first communication device may specifically be information such as latitude and longitude information or a zone ID of the first communication device. The zone ID may be used to indicate the area where the first communication device is currently located. The zone ID is associated with the latitude and longitude information. For example, the latitude and longitude information within a certain range (such as 100 square meters or other ranges) corresponds to the same zone ID.

[0085] Exemplarily, before S101, the first communication device may send the location information of the first communication device to the third communication device. The location information is related to the first resource information, and can be specifically embodied as the third communication device determining the first resource information based on the location information. Specifically, the first communication device may report its own location information during the initial access to the third communication device, and the third communication device may store its location information. For another example, the first communication device may send a request message to the third communication device to request the above recommended resources or the above non-recommended resources, and the first communication device may carry its own location information in the request message. For another example, the third communication device may request the location information from the first communication device, and the first communication device may report its location information based on the request from the third communication device. For another example, the first communication device may also periodically report its own location information to the third communication device after accessing the third communication device.

[0086] In addition, the third communication device can also monitor the signaling, data or messages sent by the first communication device at the Uu air interface, based on information such as the direction of arrival, antenna tilt angle and / or antenna height of the signaling, data or messages of the first communication device at the Uu air interface.

[0087] For example, the third communication device determines the location information of the first communication device according to the beam of the signaling sent by the first communication device during the initial access process. For another example, the first communication device may send a request message to the third communication device to request the above recommended resources or the above non-recommended resources, and the third communication device may determine the location information of the first communication device according to the beam information carrying the request message.

[0088] The third communication device may obtain the first corresponding relationship, and determine the first category of resources and / or the second category of resources corresponding to the location information of the first communication device according to the first corresponding relationship. Among them, the first corresponding relationship may be a corresponding relationship between the location information and the first category of resources and / or the second category of resources. Specifically, the first corresponding relationship may include a corresponding relationship between the location information and the first category of resources, a corresponding relationship between the location information and the second category of resources, and / or a corresponding relationship between the location information and the first category of resources and the second category of resources. An example of the first corresponding relationship is shown in Table 1.

[0089]

[0090] Table 1

[0091] As shown in Table 1, the first correspondence relationship may reflect the correspondence between one or more location information and the first category of resources and the second category of resources. When it is necessary to determine the resources related to the first communication device, the third communication device may query the first correspondence relationship shown in Table 1 according to the location information of the first communication device to determine the first resource and the second resource corresponding to the location information of the first communication device. For example, the location information of the first communication device is used to indicate that the location of the first communication device is location 4, then the third communication device may determine that the resources related to the first communication device include resource 5, resource 6, resource 7 and resource 8, wherein resource 5 and resource 6 are first category resources, and resource 7 and resource 8 are second category resources.

[0092] It should be understood that the third communication device may also store information of the first type of resources and the second type of resources for indicating the first type of resources or the second type of resources to the first communication device. For example, the third communication device may store at least one of the time domain or frequency domain location information, reference signal receiving power (RSRP), channel state information (CSI), quality of service (QoS), or feedback report of the first type of resources and the second type of resources.

[0093] In a possible example, information about the first type of resources and the second type of resources in the first corresponding relationship may be obtained by the third communication device from one or more fourth communication devices, wherein the fourth communication device may be a partially-aware UE or a fully-aware UE within the coverage of the third communication device, or a component in a partially-aware UE or a fully-aware UE within the coverage of the third communication device, such as a chip, a processing circuit, or an interface circuit. Exemplarily, the fourth communication device may include the second communication device or other UE, specifically, may be obtained from Figure 2 VUE1, VUE2, PUE or RSU etc. shown.

[0094] Below Figure 2 The VUE1, VUE2 and the third communication device are shown to specifically describe the ways to obtain information of the first type of resources and / or the second type of resources.

[0095] Exemplarily, taking VUE1 as an example, after VUE1 senses the resources near it, it can learn about the interference and occupancy of the resources near it, and VUE1 can send the first information to the third communication device. The first information may include information about resources with high interference, high occupancy, low interference or low interference, or the first information may be used to indicate the first type of resources and / or the second type of resources determined by VUE1. In addition, the first information may also include the location information of VUE1, because the location information of VUE1 is notified to the third communication device. The third communication device can also obtain the location information of VUE1 through the beam information sent by VUE1. The third communication device can store the correspondence between the location information of VUE1 and the first type of resources and / or the second type of resources based on the acquired first information and the location information of VUE1, and the correspondence may be the first correspondence or a part of the first correspondence.

[0096] For example, if the current position of VUE1 is position 1, and the resources currently determined by VUE1 through perception include resource 1 with high interference, VUE1 can send the position information corresponding to position 1 and the resource information corresponding to resource 1 (such as at least one of the time domain or frequency domain position information RSRP, CSI, QoS or feedback report) to the third communication device, so that the third communication device can store the information of resource 1 and store the correspondence between position 1 and resource 1 in the first correspondence shown in Table 1.

[0097] Specifically, VUE1 may report the above first information during the initial access to the third communication device. Alternatively, VUE1 may send the above first information to the third communication device every reporting period (hereinafter referred to as the first period, such as 1 second (s) or 10s, etc.). In addition, the third communication device may send the second information to VUE1, and trigger VUE1 to send the first information through the second information.

[0098] In addition, VUE1 may also send the first information after the reporting period arrives or the second information is received when it senses that the interference or occupancy of the nearby resources has changed; otherwise, if there is no change in the interference or occupancy of the resources, the first information may not be sent even if the reporting period arrives or the second information from the third communication device is received. For example, assuming that VUE1 sends the first information to the third communication device to indicate that resource 0 is a high-interference resource, if VUE1 detects that resource 0 becomes a low-interference resource (for example, the signal strength of resource 0 is not greater than or less than the third threshold), new first information is sent to the third communication device, and resource 0 is a low-interference resource in the new first information; if VUE1 detects that the signal strength of resource 0 is less than or less than the first threshold, that is, resource 0 is no longer a high-interference resource, new first information is sent to the third communication device, and resource 0 is not a high-interference resource in the new first information; in addition, if VUE1 detects that resource 0 is still a high-interference resource, VUE1 does not need to send new first information to save signaling and processing overhead.

[0099] In addition, the interference change amplitude threshold and / or the occupancy change amplitude threshold may be stored in VUE1 or indicated to VUE1 by the third communication device. When VUE1 determines that the interference change amplitude of a certain resource is greater than (or not less than) the signal strength change amplitude threshold, or the occupancy amplitude is greater than (or not less than) the occupancy change amplitude threshold, the sending of the first information is triggered. The interference change amplitude or the occupancy change amplitude may be an absolute value (e.g., the signal strength change amplitude, the occupancy change amplitude), wherein the interference change amplitude threshold and the occupancy change amplitude threshold may be absolute values; or may be relative values ​​(e.g., the signal strength change amplitude accounts for a percentage of the interference amplitude detected previously or this time, such as 50%).

[0100] In addition, when there are other first communication devices in the scene, such as VUE2, the third communication device can also use the above method to obtain the information of the first type of resources and / or the second type of resources determined by VUE2. Among them, VUE2 is a UE of partial perception type or full perception type. VUE2 can also send location information to the third communication device to indicate the location of VUE2 when sending the first information (or determining the first information or determining the first type of resources and / or the second type of resources), or the third communication device can determine the location information of VUE2 when sending the first information through the beam information sent by VUE2. Therefore, the third communication device can collect multiple first type resources and / or second type resources from multiple UEs within its coverage area, and store the corresponding relationship between each UE and the first type of resources and / or the second type of resources.

[0101] The third communication device can determine the correspondence between each UE's respective location information and the first and / or second category resources based on the respective location information of each UE and the correspondence between each UE and the first and / or second category resources, that is, obtain the first correspondence shown in Table 1, or obtain part of the correspondence shown in Table 1.

[0102] When determining the first resource information, the third communication device may query Table 1 according to the location information of the first communication device to obtain the first category resources corresponding to the location information or the second category resources corresponding to the location information, or obtain the first category resources and the second category resources corresponding to the location information.

[0103] It should be understood that the third communication device can store the correspondence between the location information of the first communication device and the first communication device, and is used to obtain the location of the first communication device according to the correspondence. As shown in Table 2, the third communication device can store the location information of the first communication devices such as UE1 to UE5. It should be understood that in addition to being stored in the table shown in Table 2, the correspondence can also be stored in other forms such as mapping pointers. In addition, it should be understood that the correspondence between the first communication device and the location information shown in Table 2 is not necessary for the execution of the steps shown in S101. For example, after receiving the location information of the first communication device from the first communication device, the third communication device can determine the first resource information according to the location information of the first communication device, without storing the correspondence between the first communication device and the location information of the first communication device.

[0104] First communication device Location Information UE1 Position 1 UE2 Position 1 UE3 Position 2 UE4 Location 3 UE5 Position 4 …… ……

[0105] Table 2

[0106] Thereafter, the third communication device may query the first corresponding relationship shown in Table 1 according to the location information of the first communication device shown in Table 2, obtain the first type of resources and / or the second type of resources corresponding to the first communication device, indicate the first type of resources and / or the second type of resources corresponding to the first communication device to the first communication device, and store the corresponding relationship between the first communication device and the first type of resources and / or the second type of resources. For example, as shown in Table 3, the third communication device may store the first type of resources and / or the second type of resources indicated by it for multiple first communication devices such as UE1 to UE5.

[0107]

[0108] Table 3

[0109] As shown in Table 2, the location information of UE1 is all location 1, then the third communication device can determine the resource 1 and / or resource 2 corresponding to the location 1 according to Table 1, and store the correspondence between UE1 and resource 1 and resource 2 in Table 3. Taking UE1 as an example, the first communication device can determine a first resource information to indicate that resource 1 is a first type of resource corresponding to UE1, and determine a first resource information to indicate that resource 2 is a first type of resource corresponding to UE1; or, the third communication device can determine a first resource information to indicate that resource 1 and resource 2 are the first type of resources corresponding to UE1. In other words, the third communication device can determine and store multiple first resource information, wherein each resource information corresponds to a first communication device (such as UE1, UE2, etc.), and the first resource information sent by the third communication device to one of the first communication devices is at least one of the multiple first resource information.

[0110] In another example, the third communication device may also determine the corresponding relationship shown in Table 1 or Table 3 based on the resources and corresponding location information previously allocated to other communication devices. For example, the third communication device allocates resource 3 shown in Table 1 to UE3 whose location information is location 1, and the third communication device may update Table 1 so as to set resource 3 in the updated Table 1 as a high-occupancy resource. Thereafter, if the third communication device indicates a resource to UE3 or other first communication devices again, it will indicate that resource 3 is a first-class resource.

[0111] Based on the above description, the third communication device may determine the first corresponding relationship shown in Table 1 based on information reported by multiple UEs such as VUE1 and VUE2, or in combination with information based on resources previously allocated to other communication devices.

[0112] Accordingly, the third communication device may send the first resource information to the first communication device according to the first corresponding relationship shown in Table 1 and the location information of the first communication device, so as to assist the first communication device in determining the transmission resource.

[0113] Among them, the first resource information can be sent to the first communication device during the process of the first communication device initially accessing the third communication device, or the first resource information can be sent based on the third information from the first communication device, or the third communication device can send the first resource information according to a certain period (such as the second period), and the third information is used to request the third communication device to send the first resource information.

[0114] Alternatively, the third communication device may send the first resource information after determining that the location information of the first communication device has changed. The third communication device may determine that the location information of the first communication device has changed when any of the following situations occurs: determining that the distance moved by the first communication device within a specific time period exceeds a specific distance length, such as 100 meters, based on the latitude and longitude information of the first communication device; or determining that the area of ​​the first communication device has changed based on the area identifier where the first communication device is located; or receiving indication information indicating a location information change from the first communication device.

[0115] The first communication device may also inform the third communication device of its type, and the third communication device may decide whether and how to send the first resource information to the first communication device according to the type of the first communication device. For example, the third communication device sends the first resource information to the first communication devices of the unaware type or partially aware type by default, so as to assist these first communication devices in determining the transmission resources, without the need for the first communication device to send the third information.

[0116] In addition, after each transmission of the first resource information, the third communication device may update the first resource information according to the newly reported information of the VUE and the information of the resources allocated to the first communication device and one or more of the other communication devices, and send the updated first resource information when the first resource information needs to be sent next time. For example, in the updated first resource information, the resources allocated to the first communication device and the other communication devices may be used as the first category of resources.

[0117] Alternatively, the third communication device may also update the first correspondence according to the newly reported information of the VUE and / or the information of the resources allocated to the first communication device and other communication devices, and determine the new first resource information according to the updated first correspondence when the first resource information needs to be sent next time. For example, in the updated first correspondence, the resources allocated to the first communication device and other communication devices may be used as the first category of resources.

[0118] In another implementation of S101 , the first communication device may acquire the first resource information from other surrounding UEs. For example Figure 2As shown, if the first communication device is a PUE, other UEs may include VUE1, VUE2 or RSU, etc. The first resource information sent by each UE may be used to indicate the first type of resources and / or the second type of resources perceived by the UE sending the first resource information.

[0119] Specifically, the first communication device may determine the transmission resource according to the first resource information from the second communication device, and perform side transmission to the second communication device according to the transmission resource. The second communication device is a partially sensing type or a fully sensing type UE, or a component in a partially sensing type or a fully sensing type UE.

[0120] The following is an example of PUE obtaining the second resource information from VUE1. VUE1 can sense the resources and determine the first category of resources and / or the second category of resources based on the sensed results. VUE1 can periodically send (such as sending according to the third period) the first resource information to indicate the first category of resources and / or the second category of resources modified by VUE1. The specific method of periodic sending can refer to the description when VUE1 periodically sends the first information. Alternatively, VUE1 can send the first resource information to PUE based on the fourth information sent by PUE, and the fourth information can be used to request the first resource information. The fourth information can be sent periodically. The fourth information can also be used to request VUE1 to send one first resource information or request VUE1 to send multiple first resource information according to the period. In addition, VUE1 can also send the first resource information after sensing that the interference or occupancy of nearby resources has changed, and after the reporting period arrives or the fourth information is received.

[0121] Exemplary, VUE1 may carry the location information of VUE1 and the first resource information in the same message or signaling. Alternatively, the location information of VUE1 can be obtained by the PUE through perception.

[0122] The PUE may determine whether to adopt the first resource information based on the first resource information from VUE1, the location information of VUE1, and the location information of the PUE. For example, if the location information of VUE1 is inconsistent with the location information of the PUE, such as the distance between the location of VUE1 determined according to the location information and the location of the PUE exceeds a distance threshold (such as 50 meters), the PUE may discard the first information; or, if the location information of VUE1 is consistent with the location information of the PUE, such as the distance between the location of VUE1 determined according to the location information and the location of the PUE does not exceed the distance threshold, the PUE may retain the first resource information, because the transmission resource is subsequently determined based on the first resource information.

[0123] If the PUE receives the first resource information sent by multiple UEs, the PUE can also obtain the location information of the UE as shown in Table 4, and the corresponding relationship between the first type of resources and / or the second type of resources corresponding to the UE. Among them, positions 5 to 9 shown in Table 4 are the location information of multiple UEs, and the multiple UEs include but are not limited to Figure 2 VUE1, VUE2 and RSU shown. The manner of determining the correspondence shown in Table 3 may refer to the manner in which the third communication device determines the correspondence shown in Table 1. It should be understood that each row in Table 4 may represent the correspondence between the location information of the UE and the first resource information sent by the UE. Then, according to Table 4, the location information of the UE and the first type of resources and / or the second type of resources indicated by the UE may be determined. For example, the first row in Table 4 may represent the first resource information sent by the UE at position 5 to indicate that resource 9 is a first type of resource.

[0124]

[0125] Table 4

[0126] When the PUE needs to perform side transmission, the PUE can determine the information of the first type of resources and / or the second type of resources corresponding to its own location information based on Table 4 and its own location information, and further determine the transmission resources based on the first type of resources and / or the second type of resources. For example, if the current location of the PUE is location 7, the PUE can determine that the corresponding second type of resource is resource 11, and subsequently determine the transmission resources based on the second type of resources.

[0127] In addition, in the implementation of S101, the first resource information may include the first corresponding relationship shown in Table 1. The first corresponding relationship may be broadcast by the third communication device, and the first corresponding relationship may be determined by the third communication device according to the first type of resources and / or the second type of resources reported by at least one UE. After receiving the first corresponding relationship broadcast by the third communication device, the first communication device may determine the first type of resources and / or the second type of resources corresponding to the location information of the first communication device according to the location information of the first communication device and the first corresponding relationship, and subsequently determine the transmission resources according to the first type of resources and / or the second type of resources.

[0128] Exemplary, after the first communication device determines the resources associated with the first communication device, the first communication device may store a correspondence relationship between the first communication device, the first type of resources, or the second type of resources.

[0129]

[0130] Table 5

[0131] As shown in Table 5, after determining that resource 1 is a high-interference resource related to itself, UE1 can store the corresponding relationship shown in Table 5 for subsequent determination of transmission resources according to the first type of resources or the second type of resources in the corresponding relationship.

[0132] In the implementation of S102, a possible example is that if the first communication device determines that its type is an unaware type, the first communication device may select transmission resources based on resources other than the first type of resources or based on the second type of resources. For example, resources other than the first type of resources or the second type of resources are used as transmission resources. Since the resources do not include the first type of resources, that is, do not include non-recommended resources, the first communication device is less interfered with when performing side transmission on the transmission resource. Therefore, in this implementation, the first communication device is not required to perceive the resources, or the first communication device is not required to have perception capabilities, and the first communication device obtains recommended resources from a third communication device (such as a network device) to avoid resource congestion. In this way, even if the type of the first communication device is an unaware type, the interference to the first communication device in side transmission can be reduced.

[0133] Specifically, the resources other than the first category of resources may be resources other than the first category of resources in the resource pool. For example, if the resource pool configured for UE1 includes resource 1, resource 17 and resource 18, where, as shown in Table 5, resource 1 is a first category of resources, UE1 may select a transmission resource from resource 17 and resource 18. Wherein, the method of selecting a transmission resource may include random selection or polling selection. If the random selection method is adopted, UE1 randomly selects the transmission resource from resource 17 or resource 18 each time it sends side transmission data. If the polling selection method is adopted, UE1 uses resource 17 (or resource 18) as the transmission resource when it sends side transmission data for the first time, uses resource 18 (or resource 17) as the transmission resource when it sends side transmission data next time, and uses resource 17 (or resource 18) as the transmission resource when it sends side transmission data next time, and uses resource 17 (or resource 18) as the transmission resource when it sends side transmission data next time, and so on.

[0134] In addition, the first communication device may select a transmission resource from the second type of resources indicated by the first resource information. For example, as shown in Table 4, if the current location of the first communication device is location 7, and the first resource information corresponding to location 7 indicates that resource 11 is a second type of resource, the first communication device may determine resource 11 indicated by the first resource information as a transmission resource. In addition, if there are multiple second type resources, the transmission resource may be selected by random selection or polling selection.

[0135] In another possible example, if the first communication device determines that its perception type is a partial perception type, the first communication device can determine a resource other than the first resource or a second resource as a transmission resource from the resources in the resource pool of the first communication device. In this way, the partially perceived UE can obtain recommended resources from the network device, thereby avoiding the resource congestion problem of the partially perceived UE within the time range outside the perception window. At the same time, the resource information indicated by the third communication device (such as the network device) can also enable the partially perceived UE to better select the transmission resource, which can further reduce the interference to the side transmission of the first communication device.

[0136] In addition, for the purpose of saving power consumption, when the first communication device determines that its own type is a fully-perceived type, the present solution can indicate resource information through a third communication device (such as a network device) so that the first communication device can better select transmission resources. Alternatively, the first communication device can appropriately reduce its perception of resources and determine the transmission resources based on the resource information indicated by the third communication device, thereby saving power consumption while avoiding resource congestion problems.

[0137] For example, as shown in Table 3, if UE5 determines that its perception type is a partial perception type or a full perception type, and the first resource information indicates that resources 5 and 6 are the first type of resources corresponding to UE2, and resources 7 and 8 are the second type of resources corresponding to UE5, then UE5 can randomly select or poll to select transmission resources from resources 7 and 8 for sending side transmission data through the transmission resources.

[0138] In another possible example, if the first communication device determines that its type is a partial perception type or a full perception type, and the first resource information is used to indicate the first type of resources, then in the implementation of S102, the first communication device can perceive the signal strength or occupancy rate of resources other than the first resource, and determine the transmission resource from the resources other than the first resource based on the perception result and the first resource information. In this way, the first communication device can select resources other than the first type of resources as transmission resources based on the first resource information and the perception result obtained by itself, further reducing the interference received when the selected transmission resource sends data on the side. In addition, the first communication device no longer needs to perceive the first type of resources, which can reduce power consumption.

[0139] For example, as shown in Table 3, if UE2 determines that its perception type is a partial perception type or a full perception type, and the first resource information indicates that resource 1 and resource 2 are the first type of resources corresponding to UE2, then UE2 can perceive resources other than resource 1 and resource 2 to obtain the perception results of signal strength or occupancy, and further select transmission resources from resources other than resource 1 and resource 2 based on the signal strength or occupancy, such as selecting the resource with the smallest signal strength or the lowest occupancy as the transmission resource.

[0140] In another possible example, if the first communication device determines that its type is a partial perception type or a full perception type, and the first resource information is used to indicate the first type of resources, then in the implementation of S102, the first communication device can determine the resources in the resource pool of the first communication device, and perceive all the resources in the resource pool to obtain the signal strength of these resources and the priority of the data transmitted by the resources, wherein the resources in the resource pool include the first type of resources. The priority of the data transmitted by the resource refers to the priority of the data transmitted through a certain resource perceived by the first communication device, for example, the priority of the service to which the data belongs, and the priority can be obtained based on the data transmitted on the resource received by the first communication device during the perception process.

[0141] Further, the first communication device may determine the first signal strength threshold (in decibels (dB)) of the first category of resources according to the priority of the data transmitted by the first category of resources and the priority of the side transmission data sent by the first communication device, and determine the second signal strength threshold of the first category of resources according to the first signal strength threshold, wherein the second signal strength threshold of the first category of resources is less than the first signal strength threshold of the first category of resources. Thereafter, the first communication device determines whether to use the second category of resources as a candidate resource according to the second signal strength threshold of the first category of resources and the perceived signal strength of the first category of resources. After determining whether each resource in the resource pool is a candidate resource, a transmission resource may be selected from the candidate resources, and the side transmission data may be sent through the transmission resource.

[0142] As shown in Table 6, the first communication device may store a correspondence between a signal strength threshold, a priority of the side transmission data to be sent by the first communication device, and a priority of the data transmitted by the resource perceived by the first communication device. In Table 6, pi represents the priority of the side transmission data to be sent by the first communication device, and pj represents the priority of the data transmitted by the resource perceived by the first communication device, wherein the number 1 represents a priority of 1, 2 represents a priority of 2, and so on, the higher the priority of the data, the higher the priority of the data transmission. SL-ThresRSRP_pi_pj represents the signal strength threshold corresponding to pi and pj.

[0143] SL-ThresRSRP_pi_pj( / dB) pi pj 15 1 1 10 1 2 20 2 1 …… …… ……

[0144] Table 6

[0145] After determining that there is side transmission data to be transmitted, the first communication device may determine the first signal strength threshold of the first category resource according to the corresponding relationship shown in Table 6, the priority of the side transmission data (i.e., pi), and the priority of the data transmitted by a certain first category resource (i.e., pj). For example, if pi=1, pj=1, the first signal strength threshold of the first category resource is 15dB, then according to the above method, the first communication device may determine the second signal strength threshold of the first category resource to be 10 (or other values ​​less than 15) dB. It should be understood that the corresponding relationship shown in Table 6 may be pre-stored in the first communication device, or may be sent to the first communication device by the third communication device.

[0146] Thereafter, if the first communication device determines that the signal strength of the first type of resource is less than (or not greater than) the second signal strength threshold of the first type of resource, the first communication device may use the first type of resource as a candidate resource. The first communication device may also use the resource as a candidate resource when the signal strength of the resource is less than (or not greater than) the signal strength threshold of the resource based on the perceived signal strength threshold and signal strength of other resources. The first communication device may further determine the transmission resource from all band selections, for example, based on the perceived signal strength of all candidate resources, select the smallest candidate resource in the signal as the transmission resource.

[0147] By adopting this method, the first communication device can select a transmission resource based on the perception result of each resource in the resource pool in combination with the non-recommended resource indicated by the first resource information, wherein the condition for the non-recommended resource indicated by the first resource information to be selected as a transmission resource is stricter than when the resource is not indicated as a non-recommended resource, or in other words, the condition for the non-recommended resource to be selected as a transmission resource is narrowed, so that the non-recommended resource is more difficult to be determined as a transmission resource, so as to reduce the interference received by the first communication device during the side transmission process. In addition, by adopting this method, the transmission resource finally selected can still be the first type of resource indicated by the first resource information, so the possibility of side transmission of data through the first type of resource is not ruled out, so as to improve the transmission success rate. In addition, the first communication device no longer perceives the first type of resource, which can reduce power consumption.

[0148] In another possible example, if the first communication device determines that its type is a partial sensing type or a full sensing type, and the first resource information is used to indicate the second type of resources, then in the implementation of S102, the first communication device can sense the signal strength or occupancy rate of the second type of resources, and determine the transmission resource from the second type of resources based on the sensed result and the first resource information. In this way, the first communication device can select a transmission resource from the second type of resources based on the first resource information and the sensed result obtained by itself, further reducing the interference received when the selected transmission resource sends data on the side.

[0149] For example, as shown in Table 3, if UE5 determines that its perception type is a partial perception type or a full perception type, and the first resource information indicates that resources 7 and 8 are the second type of resources corresponding to UE5, then UE5 can perceive resources 7 and 8 to obtain the perception results of signal strength or occupancy, and further select transmission resources from resources 7 and 8 based on the signal strength or occupancy, such as selecting the resource with the smallest signal strength or the lowest occupancy as the transmission resource.

[0150] In another possible example, if the first communication device determines that its own type is a partial perception type or a full perception type, and the first resource information is used to indicate the second type of resources, then in the implementation of S102, the first communication device can determine the resources in the resource pool of the first communication device, and sense all the resources in the resource pool to obtain the signal strength of these resources and the priority of the data transmitted by the resources, wherein the resources in the resource pool include the second type of resources.

[0151] Further, the first communication device may determine the first signal strength threshold of the second category resources according to the priority of the data transmitted by the second category resources and the priority of the side transmission data to be sent by the first communication device, and determine the second signal strength threshold of the second category resources according to the first signal strength threshold, wherein the second signal strength threshold of the second category resources is less than the first signal strength threshold of the second category resources. Thereafter, the first communication device determines whether to use the second category resources as a candidate resource according to the second signal strength threshold of the second category resources and the perceived signal strength of the second category resources. After determining whether each resource in the resource pool is a candidate resource, a transmission resource may be selected from the candidate resources, and the side transmission data may be sent through the transmission resource.

[0152] Among them, the method of determining the second signal strength threshold of the second type of resources can be referred to as the introduction of the aforementioned first communication device when determining the second signal strength threshold of the first type of resources.

[0153] After determining the second signal strength threshold of a second-category resource, the first communication device may determine whether to use the second-category resource as a candidate resource based on the perceived signal strength of the second-category resource and the second signal strength threshold of the second-category resource. For example, if the first communication device determines that the signal strength of the second-category resource is less than (or not greater than) the second signal strength threshold of the second-category resource, the first communication device may use the second-category resource as a candidate resource. The first communication device may also use the resource as a candidate resource based on the perceived signal strength threshold and signal strength of other resources when the signal strength of the resource is less than (or not greater than) the signal strength threshold of the resource. The first communication device may further determine a transmission resource from all the candidate resources, for example, based on the perceived signal strength of all the candidate resources, select the smallest candidate resource in the signal as the transmission resource.

[0154] In this way, the first communication device can select transmission resources based on the perception results of each resource in the resource pool and the recommended resources indicated by the first resource information, wherein the conditions for the recommended resources indicated by the first resource information to be selected as transmission resources are relaxed. In other words, the recommended resources indicated by the first resource information are more likely to be selected as resources to reduce interference received by the first communication device during side transmission.

[0155] In another possible example, if the first communication device determines that its own type is a partial perception type or a full perception type, and the first resource information is used to indicate first-category resources and second-category resources, then in the implementation of S102, the first communication device can determine the resources in the resource pool of the first communication device, and sense all the resources in the resource pool to obtain the signal strength of these resources and the priority of the data transmitted by the resources, wherein the resources in the resource pool include first-category resources and second-category resources.

[0156] Further, the first communication device may determine the first signal strength threshold of the first category resources according to the priority of the data transmitted by the first category resources and the priority of the side transmission data sent by the first communication device, and determine the second signal strength threshold of the first category resources according to the first signal strength threshold, wherein the second signal strength threshold of the first category resources is less than the first signal strength threshold of the first category resources; and the first communication device may determine the first signal strength threshold of the second category resources according to the priority of the data transmitted by the second category resources and the priority of the side transmission data sent by the first communication device, and determine the second signal strength threshold of the second category resources according to the first signal strength threshold, wherein the second signal strength threshold of the second category resources is less than the first signal strength threshold of the second category resources. The method of determining the second signal strength threshold of the first category resources and determining the second signal strength threshold of the second category resources can be referred to the above introduction and will not be repeated here.

[0157] Thereafter, the first communication device may determine whether to use the first-category resource as a candidate resource based on the second signal strength threshold of the first-category resource and the perceived signal strength of the first-category resource; and the first communication device may determine whether to use the second-category resource as a candidate resource based on the second signal strength threshold of the second-category resource and the perceived signal strength of the second-category resource. After determining whether each resource in the resource pool is a candidate resource, a transmission resource may be selected from the candidate resources, and the sideline transmission data may be sent through the transmission resource.

[0158] In this way, the transmission resource can be selected according to the perception result of each resource in the resource pool in combination with the recommended resource and the non-recommended resource indicated by the first resource information, wherein the condition for the recommended resource indicated by the first resource information to be selected as the transmission resource is relaxed, and the condition for the non-recommended resource to be selected as the transmission resource is narrowed, so as to reduce the interference received by the first communication device during the side transmission process. In addition, in this way, the transmission resource finally selected can still be the first type of resource indicated by the first resource information.

[0159] In another possible example, if the first communication device determines that its type is a partial perception type or a full perception type, and the first resource information is used to indicate first-category resources and second-category resources, then in the implementation of S102, the first communication device can determine the resources in the resource pool of the first communication device, further determine the resources other than the first-category resources in the resource pool, and sense the resources other than the first-category resources in the resource pool to obtain the signal strength of these resources and the priority of the data transmitted by the resources, wherein the resources other than the first-category resources in the resource pool include second-category resources.

[0160] Further, the first communication device may determine the first signal strength threshold of the second type of resources according to the priority of the data transmitted by the second type of resources and the priority of the side transmission data sent by the first communication device, and determine the second signal strength threshold of the second type of resources according to the first signal strength threshold, wherein the second signal strength threshold of the second type of resources is less than the first signal strength threshold of the second type of resources. The method for determining the second signal strength threshold of the second type of resources can be referred to the above introduction and will not be repeated here.

[0161] Afterwards, the first communication device may determine whether to use the second type of resource as a candidate resource based on the second signal strength threshold of the second type of resource and the perceived signal strength of the second type of resource. After determining whether each resource other than the first type of resource in the resource pool is a candidate resource, a transmission resource may be selected from the candidate resources, and the sideline transmission data may be sent through the transmission resource.

[0162] In this way, according to the first resource information, the perception result of each resource other than the first resource in the resource pool can be combined with the recommended resource indicated by the first resource information, and the transmission resource can be selected from the resources other than the first resource in the resource pool, wherein the condition for the recommended resource indicated by the first resource information to be selected as the transmission resource is relaxed, and the non-recommended resource will not be selected as the transmission resource, so as to reduce the interference received by the first communication device during the side transmission process. In addition, in this way, the first communication device no longer needs to perceive the first type of resources, so as to save power consumption.

[0163] Below through Figure 5 , describing the implementation process of a communication method provided in an embodiment of the present application. It should be understood that the method can be implemented by a first communication device, a second communication device, a third communication device, and a fourth communication device. Among them, the third communication device is a base station, the first communication device is connected to the third communication device, and the fourth communication device is located within the signal range of the third communication device. The method can be used for the first communication device to obtain a transmission resource for side transmission with the second communication device through the transmission resource.

[0164] like Figure 5 As shown, a communication method provided by the embodiment of the present application may include the following steps:

[0165] S201: At least one fourth communication device transmits the first information to the third communication device.

[0166] Among them, each fourth communication device is a UE of a partially perceptual type or a fully perceptual type within the coverage range of the third communication device.

[0167] Each first information may include the perception result of the fourth communication device sending the first information on the resource (e.g., the index of the perceived resource and the signal strength or occupancy rate of the resource), or include the information of the first category of resources and / or the information of the second category of resources perceived by the fourth communication device sending the first information. The first information may also include the location information of the fourth communication device sending the first information.

[0168] It should be understood that the first information can be sent by the fourth communication device to the third communication device according to a set period, or the fourth communication device can send the first information when it senses that the interference or occupancy of nearby resources has changed. Specifically, the method of reporting the first information according to the change of resources can refer to the aforementioned description of the method of sending the first information. In addition, the first information can also be sent by the fourth communication device after receiving the second information from the third communication device, and the second information can be used to request the fourth communication device to send the first information. Among them, the second information can be sent by the third communication device according to the set period, or it can be sent by the third communication device after receiving the request of the first communication device, or it can be sent after the first communication device accesses the third communication device (or requests access to the third communication device).

[0169] Accordingly, the third communication device receives the first information.

[0170] S202: The third communication device receives the position information of the first communication device.

[0171] Among them, the first communication device is a UE of an unaware type, a partially sense type, or a fully sense type.

[0172] Exemplarily, the first communication device may report its own location information during the initial access to the third communication device, and the third communication device stores the location information of the first communication device. In addition, the first communication device may also periodically report its own location information to obtain updated first resource information.

[0173] In addition, the first communication device may also send a third message to the third communication device to request the first resource information, and carry the location information in the third message. Alternatively, the first communication device may inform the third communication device of its own location information and type so that the third communication device decides whether to send the first resource information to the first communication device. Among them, for a first communication device of an unaware type or a partially aware type, the third communication device may send the first resource information to the first communication device by default, so as to assist the first communication device in determining the transmission resources. The third information may be sent when the first communication device initially accesses the third communication device, or may be sent periodically by the first communication device.

[0174] S203: The third communication device determines first resource information according to the first information from at least one fourth communication device and the location information from the first communication device. The first resource information is used to indicate the first type of resources and / or the second type of resources corresponding to the location information of the first communication device.

[0175] Among them, after receiving the first information from at least one fourth communication device, the third communication device can update the correspondence between the location information of the fourth communication device and the first category of resources and / or the second category of resources to the first correspondence. The first correspondence may include the correspondence between the location information of multiple fourth communication devices and the first category of resources and / or the second category of resources. In addition, if the first information includes the perception result of the resource perceived by the fourth communication device, the third communication device can determine the first category of resources and / or the second category of resources based on the perception result to obtain the correspondence between the location information of the fourth communication device and the first category of resources and / or the second category of resources. The first correspondence may be as shown in Table 1.

[0176] After receiving the location information from the first communication device, the third communication device can determine the first category resources and / or second category resources corresponding to the location information of the first communication device according to the first corresponding relationship, and determine the first resource information to indicate the first category resources and / or second category resources.

[0177] S204: The third communication device transmits the first resource information to the first communication device.

[0178] Specifically, the first resource information may be carried in a link establishment message, a resource allocation message, a downlink control signaling and its message, an initial access radio resource control (radio resource control) configuration message, etc. It should be understood that the first resource information may be sent alone or together with other information.

[0179] Accordingly, the first communication device receives the first resource information.

[0180] S205: The first communication device determines the transmission resource based on the first resource information according to its own type.

[0181] Among them, the first communication device determines the method of transmitting resources based on the first resource information according to its own type, and may include any implementation mode of the steps shown in S102 above.

[0182] S206: The first communication device transmits side-line transmission data to the second communication device according to the transmission resource.

[0183] Based on the above method, the first communication device can refer to the first resource information from the third communication device to select resources, and perform side transmission according to the selected resources. Since the first resource information can be determined based on recommended resources and / or non-recommended resources and the location information of the first communication device, the first communication device can determine the transmission resources used for transmitting side transmission data based on the recommended resources and / or non-recommended resources, which can reduce the transmission interference suffered by the side transmission.

[0184] Corresponding to the method provided in the above method embodiment, the present application embodiment also provides a corresponding device, including a module for executing the corresponding module of the above embodiment. The module can be software, hardware, or a combination of software and hardware.

[0185] Figure 6 A schematic diagram of the structure of a device is given. The device 600 may be a terminal device, or a chip, a chip system, or a processor that supports the terminal device to implement the above method. The device 600 may be used to implement the method described in the above method embodiment, and the details may refer to the description in the above method embodiment.

[0186] like Figure 6 As shown, a communication device provided in an embodiment of the present application may include a communication module 601 and a processing module 602, and the communication module 601 and the processing module 602 are coupled to each other. The communication device 600 may be used to perform the above Figure 4 or Figure 5 The steps performed by the first communication device or the third communication device shown in . The communication module 601 can be used to support the communication device 600 to communicate, and the communication module 601 can also be called a communication unit, a communication interface, a transceiver module or a transceiver unit. The communication module 601 can have a wireless communication function, for example, it can communicate with other communication devices through wireless communication. The processing module 602 can also be called a processing unit, which can be used to support the communication device 600 to perform the processing actions performed by the first communication device or the third communication device in the above method embodiment, including but not limited to: generating information and messages sent by the communication module 601, and / or, demodulating and decoding the signal received by the communication module 601, etc.

[0187] In one possible design, in an embodiment of the above-mentioned method, Figure 4 or Figure 5 When the first communication device in the steps is executed, the above processing module 602 can be used to obtain the first resource information. The setting method of the first resource information can refer to the description of the first resource information in the above method embodiment. The processing module 602 can also determine the transmission resource according to the type of the first communication device and the first resource information. The communication module 601 can be used to transmit the side transmission data through the transmission resource, for example, to send the side transmission data to the second communication device through the transmission resource.

[0188] Specifically, the processing module 602 obtains the first resource information, which may mean that the processing module 602 receives the first resource information from the communication module 601, and the first resource information may come from a third communication device, wherein the third communication device is a user device such as a network device or a head UE, a roadside processing unit, etc. In addition, the first resource information may come from a second communication device, and the second communication device may include a UE of a partial sensing type or a full sensing type, and the communication module 601 may also be used to send side transmission data to the second communication device through the transmission resource.

[0189] In one possible design, the processing module 602 may be used to determine that the type of the first communication device is an unaware type, and select a transmission resource based on resources other than the first type of resources or the second type of resources.

[0190] In one possible design, the processing module 602 may be used to determine whether the type of the first communication device is a partial sensing type or a full sensing type, and to determine a resource pool and select transmission resources from resources other than the first type of resources or the second type of resources in the resource pool.

[0191] In one possible design, if the first resource information indicates a second type of resource, the processing module 602 can be used for the type of the first communication device to be a partial sensing type or a full sensing type, and sense the second type of resource, obtain the signal strength or occupancy rate of the second type of resource, and determine the transmission resource from the second type of resource according to the sensing result. The processing module 602 senses the resource, which may include the processing module 602 receiving data sent by other UEs on the resource through the communication module 601, and the processing module 602 parsing the received data to obtain information such as the signal strength of the data transmitted on the resource, the occupancy rate of the resource, or the priority of the data sent on the resource.

[0192] In one possible design, if the first resource information indicates a first type of resource, the processing module 602 may determine whether the type of the first communication device is a partial perception type or a full perception type, and sense resources other than the first resource, obtain the signal strength or occupancy rate of the resource, and determine the transmission resource from the resources other than the first resource based on the perception result.

[0193] In one possible design, if the first resource information indicates a first type of resource, the processing module 602 may determine whether the type of the first communication device is a partial perception type or a full perception type, and sense resources other than the first resource, obtain the signal strength or occupancy rate of the resource, and determine the transmission resource from the resources other than the first resource based on the perception result.

[0194] In a possible design, if the first resource information indicates a first type of resource, the processing module 602 may determine that the type of the first communication device is a partial perception type or a full perception type, and obtain resources in a resource pool of the first communication device, where the resources in the resource pool of the first communication device include the first type of resources. The processing module 602 may also perceive the signal strength of the resources in the resource pool of the first communication device and the priority of the data transmitted by the resources. Thereafter, the processing module 602 may determine a first signal strength threshold of the first type of resource according to the priority of the sideline transmission data and the priority of the data transmitted by the first type of resource. The processing module 602 may also determine a second signal strength threshold of the first type of resource according to the first resource information, where the second signal strength threshold is less than the first signal strength threshold of the first type of resource. The processing module 602 may further determine whether to use the first type of resource as a candidate resource according to the second signal strength threshold and the signal strength of the first type of resource, where the candidate resource is used to determine the transmission resource. The processing module 602 may also determine the transmission resource from the candidate resources.

[0195] In a possible design, if the first resource information indicates the second type of resources, the processing module 602 may determine that the type of the first communication device is a partial perception type or a full perception type, and obtain the resources in the resource pool of the first communication device, and the resources in the resource pool of the first communication device include the first type of resources. The processing module 602 may also perceive the signal strength of the resources in the resource pool of the first communication device and the priority of the data transmitted by the resources, and determine the first signal strength threshold of the second type of resources according to the priority of the side transmission data and the priority of the data transmitted by the perceived second type of resources. The processing module 602 may also determine the second signal strength threshold of the second type of resources according to the first resource information, and the second signal strength threshold is less than the first signal strength threshold of the second type of resources. Further, the processing module 602 may also determine whether to use the second type of resources as a candidate resource according to the second signal strength threshold and the signal strength of the second type of resources, and the candidate resource is used to determine the transmission resource. The subsequent processing module 602 may also determine the transmission resource from the candidate resources.

[0196] In a possible design, if the first resource information indicates the first type of resources and the second type of resources, the processing module 602 may determine that the type of the first communication device is a partial perception type or a full perception type, and obtain the resources in the resource pool of the first communication device. The resources in the resource pool of the first communication device include the first type of resources and the second type of resources. The processing module 602 may also perceive the signal strength of the resources in the resource pool of the first communication device and the priority of the data transmitted by the resources, and determine the first signal strength threshold of the first type of resources according to the priority of the side transmission data and the priority of the data transmitted by the first type of resources, and determine the first signal strength threshold of the second type of resources according to the priority of the side transmission data and the priority of the data transmitted by the second type of resources. Thereafter, the processing module 602 may also determine the second signal strength threshold of the first type of resources and the second signal strength threshold of the second type of resources according to the first resource information, wherein the second signal strength threshold of the first type of resources is less than the first signal strength threshold of the first type of resources, and the second signal strength threshold of the second type of resources is less than the second signal strength threshold of the second type of resources. Further, the processing module 602 may also determine whether to use the first type of resource as a candidate resource according to the second signal strength threshold of the first type of resource and the signal strength of the first type of resource, and determine whether to use the second type of resource as a candidate resource according to the second signal strength threshold of the second type of resource and the signal strength of the second type of resource, and the candidate resource is used to determine the transmission resource. Thereafter, the processing module 602 may also determine the transmission resource from all band selections.

[0197] In a possible design, if the first resource information indicates the first type of resources and the second type of resources, the processing module 602 may determine that the type of the first communication device is a partial perception type or a full perception type, and obtain the resources in the resource pool of the first communication device.

[0200] In a possible example, the communication module 601 may receive first information from a fourth communication device, and the first information is used to indicate the first type of resources and / or the second type of resources determined by the fourth communication device.

[0201] In a possible example, the communication module 601 may receive the first information during the process of the fourth communication device initially accessing the third communication device.
