Description

Technical Field

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

[0002] In the communication transmission process, a terminal device can communicate with the network device through an uplink channel (UL) and with other terminal devices through a sidelink channel (SL). Figure 1 In the communication scenario within the coverage of the network device in the New Radio (NR) vehicle-to-everything (V2X) shown in the figure, in the same time slot, the terminal device 1 can communicate with the network device through the uplink channel, i.e., UL communication, and can also communicate with the terminal device 2 through the side channel, i.e., SL communication. However, when the terminal device determines that the uplink information and the side channel overlap in time, since the terminal device's own transmission power is limited, the terminal device needs to consider the power allocation between the uplink channel communication and the side channel communication. Even in extreme cases, when the terminal device cannot support both the uplink channel communication and the side channel communication at the same time, it needs to abandon one of the communication channels and communicate only on one channel. Therefore, the terminal device needs to determine how to perform channel communication.

[0003] The solution currently provided for the case where the uplink channel and the side channel of the terminal device overlap in time is that when the priority value of the data carried by the uplink channel is not greater than the set first priority threshold, the uplink channel communication is given priority; when the priority value of the data carried by the uplink channel is greater than the first priority threshold, and the priority value of the data carried by the side channel is not greater than the second priority threshold, the side channel communication is given priority; when the priority value of the data carried by the uplink channel is greater than the first priority threshold, and the priority value of the data carried by the side channel is greater than the second priority threshold, the uplink channel transmission is given priority. Among them, the lower the priority value of the data, the higher the priority.

[0004] As NR V2X technology continues to improve, existing solutions to channel conflicts may not be applicable to more complex scenarios. Summary of the invention

[0005] The present application provides a communication method and device for providing a transmission scheme when an uplink channel and a side channel overlap in time and the uplink channel contains side reporting information, more comprehensively considering the priority between the information carried by the uplink channel and the side channel, and improving communication reliability.

[0006] In a first aspect, an embodiment of the present application provides a communication method, including:

[0007] Determine that an uplink channel and a side channel overlap in time, the uplink channel being used to carry side reporting information and / or uplink information, and the side channel being used to carry side information; compare the priority of the side information with the priority of the side reporting information; and send the uplink channel and / or the side channel according to the priority of the side information and the priority of the side reporting information.

[0008] Based on this scheme, when the embodiment of the present invention determines that the uplink channel and the side channel overlap in time, and the uplink channel is used to carry side reporting information and / or uplink information, and the side channel is used to carry side information, a more reasonable and effective communication method is provided by comparing the priority of the side information with the side reporting information, thereby more comprehensively considering the priority between the information carried by the uplink channel and the side channel, and improving communication reliability.

[0009] In a possible implementation manner, the priorities of the sidelink information and the uplink information are compared.

[0010] Based on this solution, when comparing the priorities of the side information and the side reporting information, the embodiment of the present invention also compares the priorities of the side information and the uplink information, thereby making the solution more complete and effective.

[0011] In one possible implementation, when the priority of the uplink information is lower than the priority of the sidelink information, the priority of the sidelink information is compared with the priority of the sidelink reporting information; or when the priority of the sidelink reporting information is lower than the priority of the sidelink information, the priority of the uplink information is compared with the priority of the sidelink information.

[0012] Based on this scheme, the comparison method of the embodiment of the present invention is flexible and changeable during the communication transmission process. For example, the priority of the uplink information and the priority of the sidelink information can be compared first, or the priority of the sidelink reporting information and the priority of the sidelink information can be compared first, which is more adaptable.

[0013] In a possible implementation, a channel whose transmission power needs to be reduced is determined according to the priority of the side information and the side reporting information; or a channel whose communication needs to be prioritized is determined according to the priority of the side information and the side reporting information.

[0014] Based on this solution, the embodiments of the present invention provide how to determine a channel for priority communication when the terminal device does not support simultaneous transmission of uplink channels and side channels, and provide how to determine a channel for reducing transmission power when the terminal device supports simultaneous transmission of uplink channels and side channels.

[0015] In one possible implementation, the transmission power of the uplink channel or the sidelink channel is reduced according to the priority of the sidelink information and the sidelink reporting information; or the uplink channel or the sidelink channel is sent preferentially according to the priority of the sidelink information and the sidelink reporting information.

[0016] In a possible implementation, the side channel carries at least one side information, and each side information corresponds to a priority value; wherein the priority value of the side information is the maximum value or minimum value of at least one priority value corresponding to the side information; the uplink channel carries at least one side reporting information, and each side reporting information corresponds to a priority value; wherein the priority value of the side reporting information is the maximum value or minimum value of at least one priority value corresponding to the side reporting information; the uplink channel carries at least one uplink information, and each uplink information corresponds to a priority value; wherein the priority value of the uplink information is the maximum value or minimum value of at least one priority value corresponding to the uplink information.

[0017] Based on this solution, an embodiment of the present invention provides how to determine the priority value of the sidelink reporting information; how to determine the priority value of the sidelink information; and how to determine the priority value of the uplink information.

[0018] In a possible implementation, the larger the priority value of the sidelink reporting information is, the lower the priority of the sidelink reporting information is; the larger the priority value of the sidelink information is, the lower the priority of the sidelink information is; the larger the priority value of the uplink information is, the lower the priority of the uplink information is.

[0019] Based on this scheme, an embodiment of the present invention provides a method for determining the priority of the information according to the priority value corresponding to the information. For example, the larger the priority value of the sidelink reporting information, the lower the priority of the sidelink reporting information; the larger the priority value of the sidelink information, the lower the priority of the sidelink information; the larger the priority value of the uplink information, the lower the priority of the uplink information.

[0020] In one possible implementation, when the priority of the sidelink reporting information and the priority of the uplink information are lower than the priority of the sidelink information, it is determined that the transmission power of the uplink channel needs to be reduced; or when the priority of the sidelink reporting information and / or the priority of the uplink information are higher than the priority of the sidelink information, it is determined that the transmission power of the sidelink channel needs to be reduced.

[0021] Based on this solution, when the terminal device supports simultaneous transmission of an uplink channel and a side channel, an embodiment of the present application provides a method for determining how to reduce the transmission power of a certain channel according to the priority of the two channels.

[0022] In one possible implementation, when the priority of the sidelink reporting information and the priority of the uplink information are lower than the priority of the sidelink information, it is determined that the sidelink channel communication needs to be given priority; or when the priority of the sidelink reporting information and / or the priority of the uplink information are higher than the priority of the sidelink information, it is determined that the uplink channel communication needs to be given priority.

[0023] Based on this solution, when the terminal device does not support simultaneous transmission of the uplink channel and the side channel, the embodiment of the present application provides a method for determining how to give priority to communication on a certain channel based on the priorities of the two channels.

[0024] In a possible implementation, when the priority value of the uplink information is greater than a first priority threshold and the priority value of the sidelink information is not greater than a second priority threshold, it is determined that the priority of the uplink information is lower than the priority of the sidelink information.

[0025] Based on this scheme, an embodiment of the present invention provides a method for determining the priority of the uplink information and the priority of the sidelink information. For example, when the priority value of the uplink information is greater than the first priority threshold and the priority value of the sidelink information is not greater than the second priority threshold, it is determined that the priority of the uplink information is lower than the priority of the sidelink information.

[0026] In one possible implementation, when the priority value of the side reporting information is not greater than the priority value of the side information, and / or the priority value of the side reporting information is not greater than a second priority threshold, it is determined that the priority of the side reporting information is higher than the priority of the side information; or when the priority value of the side reporting information is less than the priority value of the side information, and / or the priority value of the side reporting information is less than a second priority threshold, it is determined that the priority of the side reporting information is higher than the priority of the side information.

[0027] Based on this scheme, an embodiment of the present invention provides a method for determining the priority of the side reporting information and the priority of the side reporting information. For example, when the priority value of the side reporting information is not greater than the priority value of the side reporting information, it is determined that the priority of the side reporting information is higher than the priority of the side reporting information; or when the priority value of the side reporting information is not greater than the second priority threshold, it is determined that the priority of the side reporting information is higher than the priority of the side reporting information; or again, when the priority value of the side reporting information is not greater than the priority value of the side reporting information and the priority value of the side reporting information is not greater than the second priority threshold, it is determined that the priority of the side reporting information is higher than the priority of the side reporting information.

[0028] In one possible implementation, the first priority threshold is indicated by a network device; or the first priority threshold is determined by a high-level terminal device; or the first priority threshold is preconfigured; the second priority threshold is indicated by a network device; or the second priority threshold is determined by a high-level terminal device; or the second priority threshold is preconfigured.

[0029] Based on this solution, the embodiment of the present invention provides several ways to determine the first priority threshold and the second priority threshold.

[0030] In a second aspect, an embodiment of the present application further provides a communication method, including:

[0031] Determining that the uplink channel does not support simultaneously sending the generated sidelink reporting information and the uplink information; and sending one of the sidelink reporting information and the uplink information on the uplink channel.

[0032] Based on this scheme, in an embodiment of the present invention, when an uplink channel carries sidelink reporting information and uplink information, and the uplink channel does not support simultaneous transmission of the sidelink reporting information and the uplink information, one report is selected from the sidelink reporting information and the uplink information, thereby providing a more reasonable and more effective communication method and solving the communication transmission problem in this scenario.

[0033] In a possible implementation manner, the priority of the sidelink reporting information is compared with the priority of the uplink information; and according to the comparison result, one of the sidelink reporting information and the uplink information is sent on the uplink channel.

[0034] Based on this solution, an embodiment of the present invention provides a method for selecting reporting information, for example, comparing the priority of the side reporting information and the reporting information, and selecting a report from the side reporting information according to the comparison result, thereby making the solution more complete, effective and adaptable.

[0035] In one possible implementation, when the priority value of the sidelink reporting information is less than the second priority threshold and the priority value of the uplink information is greater than the first priority threshold, the sidelink reporting information is sent on the uplink channel; or when the priority value of the sidelink reporting information is less than the second priority threshold, the sidelink reporting information is sent on the uplink channel.

[0036] Based on this solution, the embodiment of the present invention specifically introduces how to compare the priorities of two information and a method for determining the reported information according to the priorities of the two information.

[0037] In one possible implementation, the uplink channel carries at least one sidelink reporting information, and each sidelink reporting information corresponds to a priority value; wherein the priority value of the sidelink reporting information is the maximum value or minimum value of at least one priority value corresponding to the sidelink reporting information; the uplink channel carries at least one uplink information, and each uplink information corresponds to a priority value; wherein the priority value of the uplink information is the maximum value or minimum value of at least one priority value corresponding to the uplink information.

[0038] Based on this solution, an embodiment of the present invention provides how to determine the priority value of the sidelink reporting information and how to determine the priority value of the uplink information.

[0039] In one possible implementation, the first priority threshold is indicated by a network device; or the first priority threshold is determined by a high-level terminal device; or the first priority threshold is preconfigured; the second priority threshold is indicated by a network device; or the second priority threshold is determined by a high-level terminal device; or the second priority threshold is preconfigured.

[0077] The present application will be described in detail below with reference to the accompanying drawings.

[0078] In the process of communication transmission, it is often involved that a terminal device can communicate with network devices through an uplink channel, i.e., uplink channel communication, and can also communicate with other terminal devices through a side channel, i.e., side channel communication. For example, the device-to-device (D2D) application scenario and the vehicle-to-everything (V2X) application scenario often require the application of the Sidelink technology. Among them, the V2X refers to the technology for establishing communication between high-speed devices represented by vehicles and anything in the outside world, such as Figure 2 As shown, it includes vehicle-to-vehicle communication (Vehicle to Vehicle, V2V), vehicle-to-pedestrian communication (Vehicle to Pedestrian, V2P), vehicle-to-infrastructure communication (Vehicle to Infrastructure, V2I), and vehicle-to-network communication (Vehicle to Network, V2N).

[0079] For example, as mentioned above Figure 1 In the communication scenario within the coverage of the network device under the New Radio (NR) V2X shown, in the same time slot, the terminal device 1 can communicate with the network device on the uplink channel and on the side channel with the terminal device 2. However, when the uplink channel and the side channel of the terminal device overlap in time, since the transmission power of the terminal device itself is limited, the terminal device needs to consider the power allocation between the uplink channel and the side channel communication. Even in extreme cases, when the terminal device cannot support both the uplink channel and the side channel communication at the same time, it is necessary to abandon one of the transmission channels and transmit on only one channel. Therefore, the terminal device needs to determine how to perform channel transmission.

[0080] The following solutions are currently provided for the case where the uplink channel and the side channel of the terminal device overlap in time:

[0081] like Figure 3As shown, the existing uplink channel and side channel use different priority thresholds to distinguish between emergency services and non-emergency services. When the priority value of the data carried by the uplink channel is greater than the first priority threshold, the data carried by the uplink channel is considered to be UL non-emergency services; when the priority value of the data carried by the uplink channel is not greater than the first priority threshold, the data carried by the uplink channel is considered to be UL emergency services; when the priority value of the data carried by the side channel is greater than the second priority threshold, the data carried by the side channel is considered to be UL non-emergency services; when the priority value of the data carried by the side channel is not greater than the second priority threshold, the data carried by the side channel is considered to be SL emergency services. Among them, the lower the priority value of the data, the higher the priority.

[0082] Furthermore, when the priority value of the data carried by the uplink channel is lower than the set first priority threshold, the priority of the uplink channel is higher than the side channel, and the uplink channel communication is given priority; when the priority value of the data carried by the uplink channel is greater than the first priority threshold, and the priority value of the data carried by the side channel is not higher than the second priority threshold, the priority of the side channel is higher than the uplink channel, and the side channel communication is given priority; when the priority of the data carried by the uplink channel is not lower than the first priority threshold, and the priority value of the data carried by the side channel is higher than the second priority threshold, the priority of the uplink channel is higher than the priority of the side channel, and the uplink channel communication is given priority. In other words, it can be understood that the sending order is UL emergency services>SL emergency services>UL non-emergency services>SL non-emergency services.

[0083] However, with the continuous improvement of NR V2X technology, the terminal device can carry a part of the SL-related data during uplink channel communication, that is, the side reporting information, such as the uplink control information (Uplink Control Information, UCI) may include the SL scheduling request (Scheduling Request, SR), SL hybrid automatic repeat request (Hybrid Automatic Repeat reQuest, HARQ) feedback information and SL channel state information (Channel State Information, CSI) part or all. For another example, the terminal device can also report the SL buffer status report (Buffer Status Report, BSR) information through UL data.

[0084] However, currently there is no transmission solution for the case where the uplink channel and the side channel overlap in time and the uplink channel contains the side channel reporting information.

[0085] For example, in some scenarios, assume that the uplink channel of the terminal device carries UL non-emergency services and SL emergency services (for example, SL1), and the side channel carries SL emergency services (for example, SL2), but the priority of the SL services carried in the side channel is not as high as the priority of the SL services carried in the uplink channel (that is, the priority of SL1 is higher than the priority of SL2). At this time, if the SL services in the UL transmission are not considered (that is, SL1 is not considered), according to the existing communication transmission criteria, the priority of the side channel is higher than the priority of the uplink channel. However, the uplink channel actually carries a higher priority SL service, and the uplink channel should be given a higher priority. Therefore, the existing communication transmission criteria are not applicable to the above scenarios.

[0086] To solve the above problems, an embodiment of the present application provides a communication method. The technical solution of the embodiment of the present application can be applied to various communication systems, such as: long term evolution (LTE) system, worldwide interoperability for microwave access (WiMAX) communication system, future fifth generation (5G) system, such as new generation wireless access technology (NR), and future communication systems, such as 6G system.

[0087] Taking the 5G system (also called the New Radio system) as an example, specifically, the embodiments of the present application provide a corresponding transmission design to address the problem that the uplink channel and the side channel overlap in time and the uplink channel contains side reporting information, which is currently not taken into account. It further improves the transmission method when the uplink channel and the side channel overlap in time.

[0088] To facilitate understanding of the embodiments of the present application, first Figure 4 The communication system shown in FIG. 1 is used as an example to describe in detail the communication system to which the present application embodiment is applicable. Figure 4 As shown, the communication system includes a network side device 400, a sending terminal device 410 and a receiving terminal device 420.

[0089] The network side device 400, for example, includes access network (AN) equipment and radio access network (RAN) equipment. The access network equipment, such as a base station (e.g., an access point), may refer to a device in the access network that communicates with a wireless terminal device through one or more cells at an air interface. The base station may be used to convert received air frames to and from Internet Protocol (IP) packets, and serve as a router between the terminal device and the rest of the access network, wherein the rest of the access network may include an IP network. The network side device may also coordinate the attribute management of the air interface. For example, the network side device may include an evolved base station (NodeB or eNB or e-NodeB, evolved Node B) in a long term evolution (LTE) system or an advanced long term evolution (LTE-A), or may also include a next generation node B (next generation node B, gNB) or a next generation evolved node B (next generation evolved nodeB, ng-eNB), en-gNB (enhanced next generation node B, gNB) in a fifth generation mobile communication technology (the 5th generation, 5G) new radio (new radio, NR) system: an enhanced next generation base station; it may also include a centralized unit (CU) and a distributed unit (DU) in a cloud radio access network (CloudRAN) system, or it may also include a relay device, which is not limited in the embodiments of the present application.

[0090] The sending terminal device 410 and the receiving terminal device 420 are devices that provide voice and / or data connectivity to users, and may also be referred to as user equipment (UE), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent or user device. The terminal in the embodiment of the present application may be a mobile phone, a tablet computer (Pad), a computer with wireless transceiver function, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in self driving, a wireless terminal in remote medical, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, etc.

[0091] Among them, Figure 5 As shown, the sending terminal device 410 and the receiving terminal device 420 mainly include a sending module, a processing module and a receiving module. Among them, in an optional manner in the embodiment of the present application, the sending module is used to send data to the network device and other terminal devices, the processing module is used to process the received data and determine the data to be sent, and the receiving module is used to receive data from the network device and other terminal devices.

[0103] It should be noted that the above introduction to the channels or signals carried by the uplink channel and the side channel is for illustrative purposes only and is not intended to be a limitation of the embodiments of the present application. Any carrying conditions of the uplink channel and the side channel are applicable to the embodiments of the present application and fall within the scope of protection of the embodiments of the present application.

[0104] In addition, for the sake of simplicity in the embodiments of the present application, the UL service carried in the uplink channel is represented by uplink information, the SL service carried in the uplink channel is represented by sidelink reporting information, and the SL service carried in the sidelink channel is represented by sidelink information.

[0105] Through the above application scenarios and the introduction of uplink channels and side channels, the present application embodiment provides a communication method, which can be specifically referred to in Figure 7 The steps described.

[0106] S700, determining that an uplink channel and a sidelink channel overlap in time, the uplink channel is used to carry sidelink reporting information and / or uplink information, and the sidelink channel is used to carry sidelink information;

[0107] S701, comparing the priority of the sidewalk information with the priority of the sidewalk reporting information;

[0108] S700: Send the uplink channel and / or the sidelink channel according to the priority of the sidelink information and the priority of the sidelink reporting information.

[0109] The following is for the above Figure 7 The process of the communication method in the embodiment of the present application is specifically introduced, wherein the execution subject of the communication method can be a terminal device, or a component with terminal device functions, or a chip or chip system that implements the communication function in the terminal device, etc. The following description only takes the sending terminal device as an example and is not limited to this.

[0110] In the embodiment of the present application, when the terminal device transmits the uplink channel and the side channel concurrently, the communication transmission process can be specifically referred to in Figure 8 The steps described.

[0111] S800: The sending terminal device determines that the uplink channel and the sidelink channel overlap in time.

[0112] Among them, an optional method in the embodiment of the present application is that after the sending terminal device receives an uplink channel communication request from the network device, it receives a side channel communication request sent by the receiving terminal device within a preset time; or after the sending terminal device receives a side channel communication request from the receiving terminal device, it receives an uplink channel communication request sent by the network device within a preset time, then the sending terminal device determines that the uplink channel and the side channel overlap in time, that is, the uplink channel and the side channel are concurrent.

[0113] S801, the terminal device determines that the uplink channel carries the sidelink reporting information.

[0114] Specifically, the uplink channel carries the sidelink reporting information and the uplink information; or the uplink channel carries the sidelink reporting information.

[0115] In an optional manner in an embodiment of the present application, the terminal device determines whether the uplink channel carries the side reporting information based on an uplink channel communication request sent by the network device; or the terminal device determines whether the uplink channel carries the side reporting information based on its own business needs.

[0116] Exemplarily, for example, in the uplink channel communication request sent by the network device, it is indicated that the terminal device needs to send SL related information to the network device, then the terminal device determines that the uplink channel carries the side reporting information. For another example, the terminal device needs to send SL related information to the network device according to its own business needs, then the terminal device determines that the uplink channel carries the side reporting information.

[0117] In addition, in an embodiment of the present application, if the terminal device determines that the uplink channel does not carry the sidelink reporting information, the terminal device continues to execute according to the existing method of determining the priority of communication transmission.

[0118] S802, the terminal device determines whether the priority of the sidewalk reporting information is higher than the priority of the sidewalk information, if so, execute S803, if not, execute S804.

[0119] In the embodiment of the present application, there are multiple ways to determine whether the priority of the sideline reporting information is higher than the priority of the sideline information, which are not limited to the following ways:

[0120] Determination method 1: when the priority value of the side reporting information is not greater than the priority value of the side information, it is determined that the priority of the side reporting information is higher than the priority of the side information; or when the priority value of the side reporting information is less than the priority value of the side information, it is determined that the priority of the side reporting information is higher than the priority of the side information.

[0121] Exemplarily, in an embodiment of the present application, the terminal device determines the priority value of the side reporting information and the priority value of the side information, and then compares the priority values ​​of the side reporting information and the side information to determine the priority of the side reporting information and the side information.

[0122] For example, when the priority value of the sidewalk reporting information is not greater than the priority value of the sidewalk information, the terminal device determines that the priority of the sidewalk reporting information is higher than the priority of the sidewalk information.

[0123] That is, when the priority value of the sidewalk reporting information is less than or equal to the priority value of the sidewalk information, it is regarded that the priority of the sidewalk reporting information is higher than the priority of the sidewalk information.

[0124] For another example, when the priority value of the sidewalk reporting information is smaller than the priority value of the sidewalk information, the terminal device determines that the priority of the sidewalk reporting information is higher than the priority of the sidewalk information.

[0125] That is to say, only when the priority value of the side reporting information is smaller than the priority value of the side information, the priority of the side reporting information is regarded as higher than the priority of the side information; when the priority value of the side reporting information is equal to the priority value of the side information, the priority of the side reporting information is regarded as lower than the priority of the side information.

[0126] Furthermore, in an embodiment of the present application, the terminal device can determine the priority corresponding to the information through information related to the priority value pre-specified by the network device.

[0127] In addition, the terminal device can also determine the priority corresponding to the information through its own pre-specified priority value related information. Several examples are briefly listed below. It should be noted that the following examples are not intended to limit the embodiments of the present application.

[0128] Example 1: The configuration information of the downlink control information (DCI) or the radio resource control (RRC) for scheduling the uplink channel includes priority indication information, such as the priority indicator field in the DCI, which indicates a priority value, such as a priority index value. The larger the priority value, the higher the priority. The priority indicator can be 1 bit, indicating 2 priority index values: "1" indicates a higher priority, and "0" indicates a lower priority. The priority of the uplink information can be determined according to the priority index value.

[0129] Example 2: When the sidelink reporting information includes SL HARQ-ACK, the priority of SL HARQ-ACK is determined by the priority of the corresponding sidelink physical feedback channel (Physical Sidelink Feedback Channel, PSFCH).

[0130] When multiple PSFCHs are multiplexed in one SL HARQ-ACK, the terminal device may determine the maximum value or the minimum value of all PSFCH priority values ​​as the priority of the SL HARQ-ACK.

[0131] Example 3: The network device or the terminal device pre-specifies a priority value for at least one uplink information, and the larger the priority value, the lower the priority of the uplink information. Similarly, the network device or the terminal device pre-specifies a priority value for at least one sidelink reporting information and / or sidelink information, and the larger the priority value, the lower the priority of the information.

[0132] For example, if the network device or the terminal device pre-specifies the priority of all sidelink reporting information contained in the uplink channel, the terminal device can determine the maximum or minimum value of the priority values ​​of all sidelink reporting information contained in the uplink channel as the priority corresponding to the sidelink reporting information.

[0133] Similarly, if the network device or the terminal device pre-specifies the priority of all side information contained in the side channel, the terminal device determines the maximum or minimum value of the priority values ​​of all side information contained in the side channel as the second priority corresponding to the side information.

[0134] In addition, if the network device or the terminal device has pre-specified the priority of only part of the sidelink reporting information contained in the uplink channel, the terminal device can determine the maximum or minimum value of the priority value of the part of the sidelink reporting information contained in the uplink information as the first priority corresponding to the sidelink reporting information.

[0135] Similarly, if the network device or the terminal device has pre-specified the priority of only part of the side information contained in the side channel, the terminal device will determine the maximum or minimum value of the priority value of the part of the side information contained in the side channel as the second priority corresponding to the side information.

[0136] Determination method 2: when the priority value of the side reporting information is not greater than the second priority threshold, determine that the priority of the side reporting information is higher than the priority of the side information; or when the priority value of the side reporting information is less than the second priority threshold, determine that the priority of the side reporting information is higher than the priority of the side information.

[0137] Exemplarily, in an embodiment of the present application, the terminal device determines the priority value of the side reporting information, and then compares the priority value of the side reporting information with the second priority threshold, thereby determining the priority of the side reporting information and the side information.

[0138] For example, when the priority value of the sidewalk reporting information is not greater than the second priority threshold, the terminal device determines that the priority of the sidewalk reporting information is higher than the priority of the sidewalk information.

[0139] That is, when the priority value of the sidewalk reporting information is less than or equal to the second priority threshold, it is regarded that the priority of the sidewalk reporting information is higher than the priority of the sidewalk information.

[0140] For another example, when the priority value of the sidewalk reporting information is less than the second priority threshold, the terminal device determines that the priority of the sidewalk reporting information is higher than the priority of the sidewalk information.

[0141] That is to say, only when the priority value of the side reporting information is less than the second priority threshold, the priority of the side reporting information is regarded as higher than the priority of the side information; when the priority value of the side reporting information is equal to the second priority threshold, the priority of the side reporting information is regarded as lower than the priority of the side information.

[0142] Among them, the priority value of the side reporting information and the method for determining the priority value of the side information refer to the introduction of the above-mentioned determination method 1, and for the sake of concise description, they are not repeated here.

[0143] Determination method 3: When the priority value of the side reporting information is not greater than the priority value of the side reporting information, and / or the priority value of the side reporting information is not greater than the second priority threshold, it is determined that the priority of the side reporting information is higher than the priority of the side reporting information; or when the priority value of the side reporting information is less than the priority value of the side reporting information, and / or the priority value of the side reporting information is less than the second priority threshold, it is determined that the priority of the side reporting information is higher than the priority of the side reporting information.

[0144] Exemplarily, in an embodiment of the present application, the terminal device determines the priority value of the side reporting information and the priority value of the side information, and then compares the priority value of the side reporting information with the second priority threshold, and compares the priority value of the side reporting information with the priority value of the side information.

[0145] For example, when the priority value of the side reporting information is not greater than the second priority threshold, and the priority value of the side reporting information is not greater than the priority value of the side information, the terminal device determines that the priority of the side reporting information is higher than the priority of the side information.

[0146] For another example, when the priority value of the side reporting information is less than the second priority threshold, and the priority value of the side reporting information is less than the priority value of the side information, the terminal device determines that the priority of the side reporting information is higher than the priority of the side information.

[0147] Among them, the priority value of the side reporting information and the method for determining the priority value of the side information refer to the introduction of the above-mentioned determination method 1, and for the sake of concise description, they are not repeated here.

[0148] S803, the terminal device performs communication on the uplink channel.

[0149] Among them, if the terminal device supports both the uplink channel and the side channel, the terminal device reduces the power of the side channel or determines that the power of the side channel needs to be reduced to ensure normal communication of the uplink channel.

[0150] If the terminal device cannot support communication of the uplink channel and the side channel at the same time, the terminal device discards the side channel and gives priority to sending the uplink channel; or determines that the uplink channel needs to be sent preferentially.

[0151] S804, the terminal device determines whether the priority of the uplink information is higher than the priority of the sidelink information, and if so, executes S803, and if not, executes S805.

[0152] Among them, in the embodiment of the present application, there are many situations for determining whether the priority of the uplink information is higher than the priority of the sidelink information, which are not limited to the following situations.

[0153] Case 1: When the downlink control information or RRC configuration information that schedules the uplink channel includes priority indication information, if the priority indication information indicates that the uplink information has a lower priority and the priority value of the sidelink information is less than the second priority threshold, then it is determined that the priority of the sidelink information is higher than the priority of the uplink information; otherwise, it is determined that the priority of the sidelink information is lower than the priority of the uplink information.

[0154] Exemplarily, when the downlink control information or RRC configuration information that schedules the uplink channel includes priority indication information, such as a priority indicator field, the field indicates a priority value, such as a priorityindex value, and the larger the priority value is, the higher the priority is, wherein the priority indicator can be 1 bit, indicating 2 priority index values: "1" indicates a higher priority, and "0" indicates a lower priority. When the priorityindex field is "0" and the priority value of the sidelink information is less than the second priority threshold, it is determined that the priority of the sidelink information is higher than the priority of the uplink information, otherwise it is determined that the priority of the sidelink information is lower than the priority of the uplink information.

[0155] If the downlink control information does not include priority indication information, the priority of the uplink information is assumed to be lower, that is, the priority index value is 0. In one possible case, the RRC configuration information may be used to provide a configured grant to the UE.

[0156] Case 2: The terminal device determines the priority value corresponding to the uplink information, wherein the larger the priority value of the uplink information is, the lower the priority of the uplink information is. For example, the priority value of the uplink information is U1, and it is determined whether U1 is greater than the first priority threshold.

[0157] If not greater than, it is determined that the priority of the uplink information is higher than the priority of the side information; if greater than, the terminal device continues to determine the priority value corresponding to the side information, wherein the larger the priority value of the side information is, the lower the priority of the side information is. For example, the priority value of the side information is S1. Then, the terminal device continues to determine whether S1 is greater than the second priority threshold. If not greater than, it is determined that the priority of the side information is higher than the priority of the uplink information; if greater than, it is determined that the priority of the uplink information is higher than the priority of the side information.

[0158] In the embodiment of the present application, the first priority threshold is indicated by the network device; or the first priority threshold is determined by the terminal device upper layer; or the first priority threshold is pre-configured. The second priority threshold is indicated by the network device; or the second priority threshold is determined by the terminal device upper layer; or the second priority threshold is pre-configured.

[0159] Furthermore, in an embodiment of the present application, if the network device or terminal device pre-specifies the priority of all uplink information contained in the uplink channel, the terminal device may determine the maximum or minimum value of the priority values ​​of all uplink information contained in the uplink channel as the priority corresponding to the uplink information.

[0160] Similarly, if the network device or terminal device pre-specifies the priority of all side information contained in the side channel, the terminal device determines the maximum or minimum value of the priority values ​​of all side information contained in the side channel as the priority corresponding to the side information.

[0161] In addition, if the network device or terminal device pre-specifies the priority of only part of the uplink information contained in the uplink channel, the terminal device can determine the maximum or minimum value of the priority value of the part of the uplink information contained in the uplink channel as the priority corresponding to the uplink information.

[0162] Similarly, if the network device or terminal device has pre-specified the priority of only part of the side information contained in the side channel, the terminal device will determine the maximum or minimum value of the priority value of the part of the side information contained in the side channel as the priority corresponding to the side information.

[0163] It should be noted that, in the embodiment of the present application, if the uplink channel only carries the side reporting information, then S804 does not need to be executed. After the terminal device determines in S802 that the priority of the side reporting information is not higher than the priority of the side information, it directly executes the following S805.

[0164] S805: The terminal device performs communication on the side channel.

[0165] Among them, if the terminal device supports both the uplink channel and the side channel, the terminal device reduces the communication power of the uplink channel to ensure the normal operation of the side channel.

[0166] If the terminal device cannot support communication on both the uplink channel and the side channel at the same time, the terminal device discards the uplink channel and gives priority to communication on the side channel.

[0167] It should be noted that the embodiments of the present application Figure 8 The sequence of the steps in the embodiment does not constitute a limitation on the embodiments of the present application. In actual application, those skilled in the art can determine the execution sequence according to actual conditions. For example, the execution sequence of S802 and S804 can be swapped.

[0168] Below, in order to better understand the communication method described in the embodiment of the present application, the embodiment of the present application provides examples for the carrying conditions of the uplink channel.

[0169] Carrying condition 1: the uplink channel only carries the sidelink reporting information.

[0170] Among them, in an optional manner in the embodiment of the present application, the priority of the sidelink reporting information is determined according to the maximum or minimum value of the priority value of the sidelink reporting information carried in the uplink channel.

[0171] Exemplarily, it is assumed that the sidelink reporting information includes SL HARQ and / or SL-triggered SR. For example, when PUCCH is transmitted, the sidelink reporting information only includes SL HARQ and / or SL-triggered SR, or when PUSCH is transmitted, the sidelink reporting information only includes SL HARQ and / or SL-triggered SR. Therefore, the priority of the sidelink reporting information is determined by the maximum or minimum value of the SL HARQ and / or SL-triggered SR service priority values.

[0172] Furthermore, in the embodiment of the present application, based on the bearer condition 1, there are multiple ways to determine communication transmission, which are not limited to the following ways.

[0173] (1) The first method of determination:

[0174] Since the uplink channel does not carry uplink information, when the priority value of the sidelink reporting information is not greater than the priority value of the sidelink information carried by the sidelink channel, the priority of the uplink channel is determined to be higher; otherwise, the priority of the sidelink channel is determined to be higher; or when the priority value of the sidelink reporting information is less than the priority value of the sidelink information carried by the sidelink channel, the priority of the uplink channel is determined to be higher; otherwise, the priority of the sidelink channel is determined to be higher.

[0175] (2) The second method of determination:

[0176] Since the uplink channel does not carry uplink information, when the priority value of the sidelink reporting information is not greater than the second priority threshold, the uplink channel is determined to have a higher priority; otherwise, the sidelink channel is determined to have a higher priority; or when the priority value of the sidelink reporting information is less than the second priority threshold, the uplink channel is determined to have a higher priority; otherwise, the sidelink channel is determined to have a higher priority.

[0177] (3) The third method of determination:

[0178] Since the uplink channel does not carry uplink information, when the priority value of the sidelink reporting information is not greater than the priority value of the sidelink information, and / or the priority value of the sidelink reporting information is not greater than the second priority threshold, it is determined that the priority of the sidelink reporting information is higher than the priority of the sidelink information; or when the priority value of the sidelink reporting information is less than the priority value of the sidelink information, and / or the priority value of the sidelink reporting information is less than the second priority threshold, it is determined that the priority of the sidelink reporting information is higher than the priority of the sidelink information.

[0179] It should be noted that, in the embodiment of the present application, if the sidelink reporting information includes not only SL HARQ and / or SL-triggered SR, but also SL CSI, since SL CSI is not a SL emergency service, SL CSI can be ignored when making a priority determination, or the default priority value of SL CSI is greater than the second priority threshold. At this time, the priority value of the sidelink reporting information is still determined by the maximum or minimum value of the priority values ​​of SL HARQ and / or SL-triggered SR services (i.e., some SL services in the sidelink reporting information).

[0180] Carrying situation 2: The uplink channel carries only the uplink information, wherein the uplink information includes DL HARQ, for example, when PUCCH is transmitted, only DL HARQ is included, or when PUSCH is transmitted, only UL-SCH and / or DL ​​HARQ is included.

[0181] Among them, in an optional manner in the embodiment of the present application, the priority value of the uplink information is determined according to the maximum value or the minimum value of the priority value of the uplink information carried in the uplink channel.

[0182] Exemplarily, the uplink information includes DL HARQ, for example, when PUCCH transmission includes only DL HARQ, or when PUSCH transmission includes only UL-SCH and DL HARQ. Wherein, for PUCCH transmission including only DL HARQ, the priority value of the uplink information is the priority value of DL HARQ. For transmission including uplink-shared channel (UL-SCH) and DL HARQ, the priority value of the uplink information is determined by the maximum or minimum value of the UL-SCH and DL HARQ service priority values.

[0183] Since the uplink channel does not contain the side reporting information, there is no need to consider the priority of the side reporting information. At this time, if the priority value of the uplink information is greater than the first priority threshold, and the priority value of the side information is not greater than the second priority threshold, the terminal device determines that the priority of the side channel is higher; otherwise, the terminal device determines that the priority of the uplink channel is higher.

[0184] It should be noted that if the reported information also includes UL CSI and / or LRR, since UL CSI and / or LRR are not UL emergency services, UL CSI and / or LRR may be ignored when making priority decisions, or the default priority value of UL CSI and / or LRR is greater than the first priority threshold. In this case, the priority value of the reported information is still determined by the maximum or minimum value of the priority values ​​of UL-SCH and DLHARQ services (i.e., some UL services in the uplink information).

[0185] Carrying situation 3: the uplink channel carries the uplink information and the sidelink reporting information.

[0186] Among them, in an optional manner in an embodiment of the present application, the priority value of the sidelink reporting information is determined according to the maximum or minimum value of the priority value of the sidelink reporting information carried in the uplink channel, and the priority value of the uplink information is determined according to the maximum or minimum value of the priority value of the uplink information carried in the uplink channel.

[0187] Exemplarily, for example, when PUCCH is transmitted, the uplink information included is DL HARQ, and the sidelink reporting information is SL-triggered SR; when PUSCH is transmitted, the uplink information included is UL-SCH, and the sidelink reporting information is SL HARQ and / or SL-triggered SR. Therefore, for PUCCH transmission, the priority value of the uplink information is the priority value of DL HARQ, and the priority value of the sidelink reporting information is the priority value of SL-triggered SR. For PUSCH transmission, the priority value of the uplink information is the priority value of UL-SCH, and the priority value of the sidelink reporting information is determined by the maximum or minimum value of the SL HARQ and / or SL-triggered SR service priority values.

[0188] Since the uplink channel contains both uplink information and sidelink reporting information, the sidelink information in the sidelink channel needs to be compared with the uplink information and the sidelink reporting information. It should be noted that the order of comparison is not limited in the embodiments of the present application.

[0189] Further, when the priority of the side information is higher than both the priority of the uplink information and the priority of the side reporting information, the terminal device determines that the priority of the side channel is higher; otherwise, the terminal device determines that the priority of the uplink channel is higher; or when the priority of the side information is higher than both the priority of the uplink information and not lower than the priority of the side reporting information, the terminal device determines that the priority of the side channel is higher; otherwise, the terminal device determines that the priority of the uplink channel is higher.

[0190] It should be noted that if the uplink information also includes UL CSI and / or link recovery request (Linkrecovery request, LRR), and / or the sidelink reporting information also includes SL CSI, since UL CSI and / or LRR are not UL emergency services and SL CSI is not SL emergency services, UL CSI and / or LRR, as well as SL CSI may be ignored when making priority determinations, or the priority values ​​of UL CSI and / or LRR, as well as SL CSI may be assumed to be higher than the corresponding priority thresholds.

[0191] In addition, in the scenario of the bearer mode 3, that is, during the uplink transmission process in which the uplink channel includes both uplink information and sidelink reporting information, there is often a situation in which the uplink information and the sidelink reporting information are not supported to be transmitted simultaneously.

[0192] Exemplarily, when the uplink information is DL HARQ and the sidelink reporting information is SL HARQ, the terminal device does not support simultaneous transmission of DL HARQ and SL HARQ. At this time, the terminal device needs to select one of the DL HARQ and SLHARQ for reporting.

[0193] To this end, the present application embodiment provides another communication transmission method, which can be specifically referred to in Fig. 9 The steps described.

[0194] S900, determining that the uplink channel does not support simultaneous transmission of the generated sidelink reporting information and the uplink information;

[0195] S901: Send one of the sidelink reporting information and the uplink information on the uplink channel.

[0196] The following is for the above Fig. 9 The process of the communication method in the embodiment of the present application is specifically introduced, wherein the execution subject of the communication method in the embodiment of the present application may be a terminal device, or a component with terminal device functions, or a chip or chip system that implements the communication function in the terminal device, etc. The following description only takes the sending terminal device as an example and is not limited to this. In the embodiment of the present application, when the terminal device determines that the uplink channel does not support the simultaneous sending of the generated side report information and the uplink information, the communication transmission process, which can be specifically referred to in Fig.10 The steps described.

[0197] S1000, the sending terminal device determines that the uplink channel carries the sidelink reporting information and the uplink information, and does not support the simultaneous transmission of the sidelink reporting information and the uplink information.

[0198] S1001, the terminal device determines whether the priority of the sidelink reporting information is higher than the priority of the uplink information, if so, execute S1002, if not, execute S1003.

[0199] In the embodiment of the present application, there are multiple ways to determine whether the priority of the sidelink reporting information is higher than the priority of the uplink information, which are not limited to the following:

[0200] Determination method 1: When the priority value of the sidelink reporting information is less than the second priority threshold, and the priority value of the uplink information is greater than the first priority threshold, determine that the priority of the sidelink reporting information is higher than the priority of the uplink information.

[0201] Exemplarily, assuming that the sidelink reporting information is SL HARQ and the uplink information is DL HARQ, when the priority value of SL HARQ is less than the second priority threshold and the priority value of DL HARQ is greater than the first priority threshold, it is determined that the priority of SL HARQ is higher than the priority of DL HARQ.

[0202] Determination method 2: When the priority value of the sidelink reporting information is less than the second priority threshold, determine that the priority of the sidelink reporting information is higher than the priority of the uplink information.

[0203] Exemplarily, assuming that the sidelink reporting information is SL HARQ and the uplink information is DL HARQ, when the priority value of SLHARQ is less than the second priority threshold, it is determined that the priority of SL HARQ is higher than the priority of DL HARQ; otherwise, it is determined that the priority of SL HARQ is lower than the priority of DL HARQ.

[0204] Determination method 3: when the sidelink reporting information exists in the uplink channel, determining that the priority of the sidelink reporting information is higher than the priority of the uplink information.

[0205] Exemplarily, assuming that the sidelink reporting information is SL HARQ and the uplink information is DL HARQ, the terminal device directly determines that the priority of the SL HARQ is higher than the priority of the DL HARQ.

[0206] Determination method 4: when the uplink information exists in the uplink channel, determining that the priority of the uplink information is higher than the priority of the reporting information.

[0209] Exemplarily, when the downlink control information or RRC configuration information for scheduling the uplink channel includes priority indication information, such as a priority indicator field, which indicates a priority value, such as a priority index value.

In a possible case, the RRC configuration information can be used to provide a configured grant to the UE.
