Although the following description describes a New Radio (NR) system for illustrative purposes, and NR technical terminology is used in much of the following description, these technologies may be used in other systems and wireless technologies, such as 6th Generation (6G) and 7th Generation (7G) systems. th The present invention can be applied to applications other than NR system applications, such as 6G (Generation, 6G) communication systems.

[0019] In the embodiment of the present application, the communication device may be a terminal or a network side device. The terminal may be called a terminal device or a user terminal (User Equipment, UE), and the terminal may be a terminal side device such as a mobile phone, a tablet personal computer, a laptop computer also called a notebook computer, a personal digital assistant (PDA), a personal digital assistant, a netbook, an ultra-mobile personal computer (UMPC), a mobile Internet device (MID), a wearable device, a vehicle-mounted device (VUE), a pedestrian terminal (PUE), etc., and the wearable device includes a wristband, an earphone, glasses, etc. It should be noted that the specific type of the terminal is not limited in the embodiment of the present application.

Here, the base station may be referred to as a Node B, an evolved Node B, an access point, a base station transceiver station (BTS), a radio base station, a radio receiver / transmitter, a basic service set (BSS), an extended service set (ESS), a B node, an evolved B node (eNB), a home B node, a home evolved B node, a WLAN access point, a WiFi node, a transmitting receiving point (TRP), or any other suitable term in the field, and as long as the same technical effect can be achieved, the base station is not limited to a specific technical term. It should be noted that in the embodiments of the present application, a base station in an NR system is simply taken as an example, but the specific type of the base station is not limited.

[0020] In order to better understand the solution provided by this application, the following will be first described.

[0021] About sidelink transmission A sidelink terminal can communicate with other terminals over the sidelink, and these terminals are usually cars, road side units (RSUs), mobile phones, etc. that support sidelink technology.

[0022] The resource allocation mode of a Vehicle to X (V2X) terminal can be divided into the following two modes:

[0023] In the first mode, the base station can schedule or control the terminal's transmission on the sidelink over the Uu interface and allocate corresponding resources to the terminal.

[0024] In the second mode, the terminal obtains its own transmission resources on the sidelink and may also be able to schedule transmissions on the sidelink of other V2X terminals.

[0025] SL Hybrid Automatic Repeat Request feedback (HARQ feedback) and reporting In order to improve the reliability and resource utilization of data transmission on the sidelink, a HARQ feedback mechanism is also introduced into the sidelink technology. That is, when a sidelink receiving user receives sidelink data (sidelink data is transmitted on a physical sidelink feedback channel (PSFCH), where the physical sidelink shared channel (PSSCH) is scheduled by system control information (SCI), and the SCI is transmitted on a physical sidelink control channel (PSCCH) and / or PSSCH), the sidelink receiving user can indicate whether the sidelink transmission is successful or unsuccessful by feeding back sidelink HARQ-ACK information, which is transmitted on the PSFCH resource. When a sidelink transmitting user receives the sidelink HARQ-ACK information on the sidelink, the user can know whether the previous transmission is successful or unsuccessful. It should be noted that one sidelink user can receive or transmit in different time or frequency domains, respectively.

[0026] The transmission of sidelink packets may be between the control node and the user (in which case the control node operates on the sidelink) or between users on the sidelink. For the latter case, the control node may not directly know whether the transmission of the sidelink packets is successful or not, and the user needs to send sidelink HARQ-ACK information (e.g., sidelink Acknowledgement (ACK) / Negative Acknowledgement (NACK)) to the control node via PUCCH or PUSCH, so that the control node can further determine whether the transmission on the sidelink is successful or not.

[0027] A user who transmits sidelink HARQ-ACK information corresponding to a certain sidelink transmission to the base station is a transmitting user who transmits this sidelink transmission. Figure 1 shows an example in which one transmitting user transmits sidelink HARQ-ACK information=NACK to the control node and an example in which one receiving user feeds back sidelink HARQ-ACK information=NACK.

[0028] If the control node is a base station, the base station needs to allocate PUCCH or PUSCH resources for reporting sidelink HARQ-ACK information, and the allocation of the PUCCH or PUSCH resources is realized by indicating a slot interval PSFCH-PUCCH offset between PSFCH and PUCCH in Radio Resource Control (RRC) or Downlink Control Information (DCI).

[0029] Sidelink physical channel priority In sidelink, different packets and services have different priorities, and the priority values ​​are expressed by 1 to 8, and the lower the priority value, the higher the priority. Specifically, the priority of data in sidelink is indicated by SCI, and the priority of feedback resource PSFCH corresponding to data is the same as the priority of data. There may be multiple PSFCH resources in one PSFCH time domain position, and these resources may correspond to different data, in which case the priority of the PSFCH time domain position is determined by the PSFCH resource with the highest priority among these PSFCH resources. The priority value of sidelink synchronization signal block (SL Synchronization Signal and PBCH block, S-SSB) may also be 1 to 8, and the specific priority value may be configured or pre-configured.

[0030] On the priority of PUCCH / PUSCH for reporting sidelink HARQ-ACK The base station can indicate PUCCH / PUSCH resources for a user to report sidelink HARQ-ACK, where one PUCCH / PUSCH resource may be associated with one or more PSFCH time domain positions, and before reporting sidelink HARQ-ACK information, the PUCCH / PUSCH resource orders and serially connects the sidelink HARQ-ACKs carried in at least some PSFCH resources in the previously associated PSFCH time domain positions in a certain order, and transmits the ordered and serially connected sidelink HARQ-ACKs to the base station. That is, one PUCCH / PUSCH resource can be associated with one or more sidelink HARQ-ACKs of data. In this case, the PUCCH / PUSCH resource is determined by the highest priority in the corresponding sidelink HARQ-ACK.

[0031] Uu transmission and Uu HARQ-ACK priority Corresponding to downlink transmission, the user may also feed back HARQ-ACK. The data of Uu is divided into two types: Enhanced Mobile Broadband (eMBB) and Ultra-reliable and Low Latency Communication (URLLC). The user may also support low priority, e.g., low priority (priority low) or priority index (priority index=0), and high priority, e.g., high priority (priority high) or priority index 1, and the corresponding HARQ-ACK has the same priority as the data, and the priority of the PUCCH / PUSCH carrying the HARQ-ACK is also the same as the priority of the data corresponding to the HARQ-ACK.

[0032] Using PUCCH / PUSCH for HARQ-ACK transmission The PUCCH can be used to transmit HARQ-ACK information. When the PUCCH and PUSCH carrying the HARQ-ACK information overlap, the user does not transmit the PUCCH, but instead multiplexes the HARQ-ACK information that was originally intended to be transmitted on the PUCCH into the PUSCH and transmits it together with the data portion in the PUSCH. In order to guarantee the performance of high-priority transmission for Uu, the conventional technology cannot multiplex a high-priority HARQ-ACK in a low-priority PUSCH for transmission, and similarly, it is not possible to multiplex a low-priority HARQ-ACK in a high-priority PUSCH for transmission. and transmit It is not possible.

[0033] In the case where the PUSCH carrying low or high priority data overlaps with the PUCCH / PUSCH carrying the sidelink HARQ-ACK, it is unclear whether and how the PUSCH can multiplex the sidelink HARQ-ACK.

[0034] This is because the priority definition of the SL HARQ-ACK and the PUCCH / PUSCH carrying the SL HARQ-ACK and the priority definition of the PUCCH / PUSCH carrying the visible downlink (DL) HARQ-ACK and the DL HARQ-ACK are two different definitions and cannot be directly compared. For example, in the SL priority, the lower the priority value, the higher the priority, whereas in the Uu priority, the higher the priority value, the higher the priority. If the sidelink HARQ-ACK is multiplexed in the PUSCH of high priority, for example, URLLC, the PUSCH reliability may decrease or the delay may increase, and if the sidelink HARQ-ACK is not multiplexed in the PUSCH of high priority, for example, URLLC, the sidelink feedback may be lost.

[0035] Referring to FIG. 2, in order to solve the above problem, an embodiment of the present application provides a transmission method applied to a communication device, which may be a terminal or a network side device, and the method includes the following step 201.

[0036] In step 201, a target transmission is determined if the target resource and the first resource at least partially overlap, or meet a collision condition, or meet a multiplexing condition.

[0037] Here, the target resource is associated with a SL, the target resource may or may not have a first Uu priority, and the first resource may or may not have a second Uu priority.

[0038] The first Uu priority of the target resource includes the Uu priority of the target resource and / or the Uu priority of at least some of the information corresponding to the target resource, and the first SL priority of the target resource includes the SL priority of the target resource and / or the SL priority of at least some of the information corresponding to the target resource.

[0039] First, the following will be explained.

[0040] Uu priority refers to a priority system associated with Uu, i.e., the priority system associated with Uu (priority index 0 and priority index 1, etc.) is defined as Uu priority. SL priority refers to a priority system associated with SL, i.e., the priority system associated with SL (e.g., priority values ​​1 to 8, etc.) is defined as SL priority.

[0041] In the present invention, the first SL priority of the target resource may be the highest or lowest SL priority in at least a part of information corresponding to the target resource, for example, the highest or lowest SL priority in the HARQ-ACK corresponding to the target resource. In the present invention, the first SL priority value of the target resource may be the highest or lowest SL priority value in at least a part of information corresponding to the target resource, for example, the highest or lowest SL priority value in the HARQ-ACK corresponding to the target resource.

[0042] In an embodiment of the present application, if the target resource and the first resource associated with the SL at least partially overlap, or satisfy a collision condition, or satisfy a multiplexing condition, it is determined whether to perform transmission, where the multiplexing condition may be understood as at least a part of the conditions that must be satisfied in order for one of the target resource and the first resource to be able to multiplex and transmit at least a part of information of the other resource.

[0043] In some embodiments, the target transmission is determined based on whether the target resource has a first Uu priority, whether the first resource has a second Uu priority, the first Uu priority of the target resource and / or the second Uu priority of the first resource.

[0044] For example, the conditions for multiplexing are that the time domains overlap and that the priority requirements are satisfied. Regarding this, if the time domains of the first resource and the target resource overlap, whether multiplexing is possible is finally determined based on whether the first Uu priority, the second Uu priority and / or the first SL priority satisfy the priority requirements.

[0045] In the embodiment of the present application, the target resource and the first resource may or may not have Uu priority. Therefore, the target transmission is determined based on whether the target resource and the first resource have Uu priority and / or on the Uu priority of both of them. That is, the target transmission is determined based on at least one of whether the target resource has a first Uu priority, whether the first resource has a second Uu priority, the first Uu priority of the target resource, and the second Uu priority of the first resource.

[0046] In some embodiments, the Uu priority is at least one of a priority indicated by physical layer signaling, a priority set at a higher layer, a service priority, and a logical channel priority.

[0047] In some embodiments, the targeted transmission is a targeted uplink transmission.

[0048] The target resource is associated with SL, which means that the target resource may be a SL resource or a Uu resource for transmitting SL information. Specifically, in one implementation, the target resource is a Uu resource for transmitting SL HARQ-ACK, such as a PUCCH for transmitting SL HARQ-ACK.

[0049] The target resource is a PUCCH that transmits SL information, and the first resource is a PUSCH or a PUCCH. If the target resource and the first resource at least partially overlap, or satisfy a collision condition, or satisfy a multiplexing condition, the following four cases can be divided:

[0050] Case 1: One of them has a corresponding DCI, and various target resources and the first resource at least partially overlap, or satisfy a collision condition, or satisfy a multiplexing condition, as shown in Table 1.

[0051] [Table 1] JPEG0007597923000002.jpg247153 JPEG0007597923000003.jpg192153

[0052] Case 2: One of them has a corresponding DCI, and various target resources and the first resource at least partially overlap, or satisfy a collision condition, or satisfy a multiplexing condition, as shown in Table 2.

[0053] [Table 2] JPEG0007597923000005.jpg242153 JPEG0007597923000006.jpg118153

[0054] Case 3: Both have corresponding DCIs, and various target resources and the first resource at least partially overlap, or satisfy a collision condition, or satisfy a multiplexing condition, as shown in Table 3.

[0055] [Table 3] JPEG0007597923000008.jpg145154

[0056] Case 4: There is no DCI in either case, and various target resources and the first resource at least partially overlap, or satisfy a collision condition, or satisfy a multiplexing condition, as shown in Table 4.

[0057] [Table 4] JPEG0007597923000010.jpg243152 JPEG0007597923000011.jpg243152 JPEG0007597923000012.jpg244153 JPEG0007597923000013.jpg102153

[0058] The SL DCI in the present invention is a DCI for scheduling or activating or deactivating SL resources, for example, DCI format (format 3-0) or DCI format 3-1, and for example, a DCI scrambled with SL-Configured Scheduling (CS)-RNTI or SL-RNTI. The SL PUCCH may be understood as a PUCCH for transmitting SL information, for example, SL HARQ-ACK. The UL DCI is a DCI for scheduling PUSCH, and the DL DCI is a DCI for scheduling PDSCH.

[0059] For at least one of the three cases with corresponding DCIs, namely case 1, case 2, and case 3, described above, the following applies:

[0060] The interval between the target resource and its corresponding DCI is T proc,2 +delta and / or the interval between the first resource and its corresponding DCI is greater than or equal to T proc,2 +delta or greater, as guaranteed by the base station and / or desired by the user.

[0061] Delta may or may not be zero and may be positive or negative.

[0062] N2 is the processing time, which may correspond to the user's capabilities.

[0063] T is the processing time or preparation time, and T may include N2. For example, the value of T is T=(N 2 +d 2,1)(2048+144)·κ2 -μ Tc, or T=max(((N 2 +d 2,1 +d 2 )(2048+144)·κ2 -μ Tc+T ext +T switch ,d 2,2 ) It is also possible to use the following.

[0064] N2 corresponds to a first particular subcarrier spacing (SCS) and / or T corresponds to a second particular SCS.

[0065] Wherein, the first specific SCS is the minimum or maximum SCS among at least some SCSs among the SCS of the first resource, the SCS of the control signaling (e.g., DCI or RRC) corresponding to the first resource, the SCS of the target resource, the SCS of the first control signaling (e.g., SL DCI indicating the target resource) corresponding to the target resource, and the SCS of the SL resource (e.g., the SL resource scheduled, activated, or deactivated by the SL DCI) corresponding to the target resource. Specifically, for example, the first specific SCS is the minimum or maximum SCS among the SCS of the first resource, the SCS of the target resource, and the SCS of the SL resource corresponding to the target resource, and also, for example, the first specific SCS is the minimum or maximum SCS among the SCS of the first resource, the SCS of the control signaling corresponding to the first resource, the SCS of the target resource, the SCS of the first control signaling corresponding to the target resource, and the SCS of the SL resource corresponding to the target resource.

[0066] Or, the first specific SCS is an SCS that maximizes or minimizes N2 among the set SCSs.

[0067] Or, the first specific SCS is the SCS that maximizes or minimizes N2.

[0068] Wherein, the second specific SCS is the minimum or maximum SCS among at least some SCSs among the SCS of the first resource, the SCS of the control signaling corresponding to the first resource, the SCS of the target resource, the SCS of the first control signaling corresponding to the target resource, and the SCS of the SL resource corresponding to the target resource. Specifically, for example, the second specific SCS is the minimum or maximum SCS among the SCS of the first resource, the SCS of the target resource, and the SCS of the SL resource corresponding to the target resource, and for example, the second specific SCS is the minimum or maximum SCS among the SCS of the first resource, the SCS of the control signaling corresponding to the first resource, the SCS of the target resource, the SCS of the first control signaling corresponding to the target resource, and the SCS of the SL resource corresponding to the target resource.

[0069] Or, the second specific SCS is an SCS that maximizes or minimizes T among the set SCSs.

[0070] Or, the second specified SCS is the SCS that maximizes or minimizes T.

[0071] The control signaling corresponding to the first resource is a control signaling (eg, DCI or RRC) that schedules, indicates, or activates the first resource.

[0072] The first control signaling corresponding to the target resource may be a SL DCI or higher layer signaling that schedules or configures or indicates the target resource.

[0073] The SL resource corresponding to the target resource may be an SL resource that is configured or scheduled or activated or deactivated by the above SL DCI or higher layer signaling.

[0074] For example, if the target resource is a PUCCH for transmitting a SL HARQ-ACK, the first control signaling corresponding to the target resource is a SL DCI or higher layer signaling that configures or indicates the target resource.

[0075] In the present invention, ultimately not transmitting at least a portion of the information of the target resource may be achieved by the base station ensuring that the target resource and the first resource do not overlap or collide, or the interval between them is greater than or equal to a predetermined value, and / or the user not wanting the target resource and the first resource to overlap or collide, or the interval between them to be smaller than a predetermined value.

[0076] The above first resource having the second Uu priority may be specifically interpreted as at least one of the following (1) and (2).

[0077] (1) The network side schedules, sets or indicates the second Uu priority of the first resource.

[0078] Specifically, in some embodiments, priority indication information (e.g., a priority indicator and / or a physical priority index (phy-PriorityIndex)) is carried in control signaling (e.g., DCI, MAC CE and / or RRC) that schedules, configures or indicates the first resource.

[0079] (2) A second Uu priority of the first resource is predefined or preconfigured.

[0080] The second Uu priority of the first resource may be predefined by a protocol. For example, if the control signaling (e.g., DCI, MAC CE, and / or RRC) that schedules, configures, or indicates the first resource does not include priority indication information (e.g., priority indicator and / or phy-PriorityIndex), the second Uu priority of the first resource is predefined as low priority or priority low or priority index 0.

[0081] The above first resource not having the second Uu priority may be specifically interpreted as at least one of the following (1) and (2).

[0082] (1) The network side does not schedule, set or indicate the second Uu priority of the first resource.

[0083] Specifically, in some embodiments, the control signaling (e.g., DCI, MAC CE and / or RRC) that schedules, configures or indicates the first resource does not include priority indication information (e.g., priority indicator and / or phy-PriorityIndex).

[0084] (2) The second Uu priority of the first resource is not predefined or preconfigured.

[0085] In some embodiments, the first resource is used for at least one of the following (1) to (8).

[0086] (1)URLLC transmission. (2) Transmissions above a priority threshold, i.e., high priority transmissions. (3) Transmission that exceeds the reliability requirement, i.e., highly reliable transmission. (4) A transmission that is lower than the delay threshold and has a packet delay budget (PDB) that is smaller than the PDB threshold or a remaining PDB that is smaller than the remaining PDB threshold, i.e., a transmission with low delay, small PDB, or small remaining PDB. At least one of the above (1) to (4) may be considered to correspond to the first priority. (5)eMBB transmission. (6) Transmissions below the priority threshold, i.e., low priority transmissions. (7) Transmission that is lower than the reliability requirement, i.e., unreliable transmission. (8) A transmission with a delay higher than the delay threshold and a PDB larger than the PDB threshold or a redundant PDB larger than the redundant PDB threshold, i.e., a transmission with a high delay, a large PDB or a large redundant PDB. At least one of the above (6) to (8) may be considered to correspond to the second priority.

[0087] In some embodiments, the method further includes determining a first Uu priority of the target resource based on the first SL priority of the target resource in accordance with a mapping relationship, which may be understood as a correspondence relationship between the first SL priority and the first Uu priority.

[0088] In an embodiment of the present application, a Uu priority corresponding to or equivalent to the SL priority is predefined for the target resource, that is, a mapping relationship is established between the first Uu priority and the first SL priority of the target resource, and the target resource is determined based on the predefined mapping relationship. resource The first SL priority of the target resource can be determined by the first SL priority of the target resource.

[0089] Furthermore, if the first Uu priority of the target resource is a specific priority, or the first SL priority of the target resource meets a specific condition, the first Uu priority of the target resource is a specific priority.

[0090] In an embodiment of the present application, when determining the first Uu priority based on the first SL priority, a unified specific priority may be adopted for all various first SL priorities, or the first Uu priority may be determined to be a specific priority corresponding to a specific condition that the first SL priority satisfies.

[0091] The above specific priority may include one or more priorities, such as, for example, high, medium, and low priority, or, for example, priorities 1, 2, 3, 4, and 5, and the embodiments of the present application do not specifically limit the types of priorities included in the specific priority.

[0092] Accordingly, the specific condition also includes one or more conditions, and selectively, different specific conditions may correspond to different specific priorities or may correspond to the same specific priority.

[0093] The following describes an example of a scene in which the specific priority level includes two types of priority levels.

[0094] Specifically, the specific priority includes at least one of a first priority and a second priority.

[0095] The above first priority may be interpreted as high priority, or priority high, or priority index 1, or URLLC, and when the first Uu priority of the target resource and / or at least some information corresponding thereto is the first priority, the target resource and / or at least some information corresponding thereto can be understood as high priority, or priority high, or priority index 1, or URLLC. For example, the first priority may correspond to a URLLC service, in which case, selectively, the target resource and / or the information corresponding thereto is considered to be URLLC, and the first Uu priority of the target resource corresponds to the priority of URLLC.

[0096] The second priority may be interpreted as low priority, or priority low, or priority index 0, or eMBB, and when the first Uu priority of the target resource and / or at least some information corresponding thereto is the second priority, the target resource and / or at least some information corresponding thereto may be understood as low priority, or priority low, or priority index 0, or eMBB. For example, the second priority may correspond to an eMBB service, in which case, selectively, the target resource and / or the information corresponding thereto is eMBB, and the first Uu priority of the target resource is considered to correspond to the priority of eMBB.

[0097] Determining a first Uu priority of the target resource based on the first SL priority of the target resource may include:

[0098] Case 1: The first Uu priority of the target resource is determined as the first priority.

[0099] Case 2: The first Uu priority of the target resource is determined as the second priority. Specifically, the specific condition includes at least one of a first condition and a second condition. The step of determining a first Uu priority of the target resource based on the first SL priority of the target resource may further include:

[0100] Case 3: If the first SL priority of the target resource satisfies a first condition, the first Uu priority of the target resource is set as the first priority, and / or, if the first SL priority of the target resource satisfies a second condition, the first Uu priority of the target resource is set as the second priority.

[0101] Furthermore, the first condition includes one or more of the following:

[0102] The first SL priority of the target resource is equal to or greater than the first predetermined priority. The first SL priority value of the target resource is less than or equal to a first predetermined priority value. The second predetermined priority and / or the second predetermined priority value is not set or obtained. It should be noted that, when the executing communication device is a network side device (e.g., a base station), the condition is that the second predetermined priority and / or the second predetermined priority value is not set, in one selectable embodiment, the second priority is the first priority, and in one selectable embodiment, the second priority value is the first priority value, and, when the executing communication device is a terminal, the condition is that the second predetermined priority and / or the second predetermined priority value is not obtained, for example, a base station is not set or a protocol is not predefined. The second condition is not met.

[0103] The second condition includes one or more of the following: The first SL priority of the target resource is equal to or greater than the third predetermined priority. The first SL priority value of the target resource is less than or equal to a third predetermined priority value. A fourth predetermined priority and / or a fourth predetermined priority value is not set or obtained. In one alternative embodiment, the fourth priority is the first priority, the second priority and / or the third priority, and in one alternative embodiment, the fourth priority value is the first priority value, the second priority value and / or the third priority value. The first SL priority of the target resource is less than or equal to the fifth predetermined priority. The first SL priority value of the target resource is greater than or equal to a fifth predetermined priority value. In one alternative embodiment, the fifth priority value is the first priority value, and in one alternative embodiment, the fifth priority value is the first priority value. The first condition is not met.

[0104] It should be noted that at least some of the first to fifth predetermined priorities may correspond to priorities corresponding to sl-priority threshold (PriorityThreshold) ULURLLC and / or sl-PriorityThreshold, and at least some of the first to fifth predetermined priority values ​​may correspond to priority values ​​corresponding to SL priority thresholds sl-PriorityThresholdULURLLC and / or sl-PriorityThreshold of UL URLLC.

[0105] For example, as an example of an embodiment in which the first Uu priority of a target resource is the first priority when the first SL priority of the target resource satisfies a first condition, if the first SL priority value of the target resource is less than or equal to sl-PriorityThreshold or sl-PriorityThresholdULURLLC, the target resource is the first priority.

[0106] As an example of an example where the first Uu priority of the target resource is the second priority when the first SL priority of the target resource satisfies the second condition, if the first SL priority value of the target resource is greater than or equal to sl-PriorityThreshold or sl-PriorityThresholdULURLLC, the target resource is the second priority.

[0107] In this embodiment, the first SL priority of the target resource may be the lowest priority value in the SL HARQ-ACK corresponding to the target resource.

[0108] It should be noted that the first to fifth predetermined priorities (values) may be the same or different, and the embodiment of the present application does not specifically limit it.

[0109] Based on the same principle, when a specific priority includes three types of priorities, high, medium, and low, determining the first Uu priority based on the first SL priority may include: (1) setting the first Uu priority as a high priority; (2) setting the first Uu priority as a medium priority; (3) setting the first Uu priority as a low priority; (4) setting the first Uu priority as a high priority if the first SL priority satisfies a first condition; (5) setting the first Uu priority as a medium priority if the first SL priority satisfies a second condition; and (6) setting the first Uu priority as a low priority if the first SL priority satisfies a third condition (the specific content of the third condition may be set by referring to the first and second conditions); and the method of determining the first Uu priority based on the first SL priority for specific priorities of other priority types may be set based on the same principle, and detailed explanation will be omitted.

[0110] In some embodiments, the first Uu priority of the target resource includes one or more of the following (1) to (3).

[0111] (1) A first specific Uu priority among Uu priorities of at least a portion of information corresponding to the target resource. The first specific Uu priority may be the highest or lowest Uu priority among the Uu priorities of the information corresponding to the target resource.

[0112] Preferably, the at least some information corresponding to the target resource is all information corresponding to the target resource, for example all HARQ-ACK bits corresponding to the target resource.

[0113] For example, if a target resource corresponds to three HARQ-ACK bits and the corresponding Uu priorities are high, low, and high respectively, the Uu priority of the target resource is high or low.

[0114] (2) A Uu priority corresponding to a specific SL priority among the SL priorities of at least a portion of information corresponding to the target resource. The specific SL priority may be a Uu priority corresponding to the highest or lowest SL priority among the SL priorities of the information corresponding to the target resource.

[0115] Preferably, the at least some information corresponding to the target resource is all information corresponding to the target resource, for example all HARQ-ACK bits corresponding to the target resource.

[0116] For example, if a target resource corresponds to three HARQ-ACK bits, and the corresponding SL priorities are SL priorities corresponding to priority values ​​1, 1, and 8 respectively, and the Uu priority corresponding to the SL priority value 1 is high, then the Uu priority of the target resource is high.

[0117] (3) Uu priority of at least some of the information corresponding to the target resource. Preferably, the at least some information corresponding to the target resource is all information corresponding to the target resource, for example all HARQ-ACK bits corresponding to the target resource.

[0118] For example, if a target resource corresponds to three HARQ-ACK bits and the corresponding Uu priorities are high / low / high respectively, the Uu priorities of the target resource include high and low.

[0119] Similarly, the first Uu priority value of the target resource includes one or more of the following (1) to (3):

[0120] (1) A first specific Uu priority value among the Uu priority values ​​of at least a portion of the information corresponding to the target resource. The first specific Uu priority value may be the highest or lowest Uu priority value among the Uu priority values ​​of information corresponding to the target resource.

[0121] Preferably, the at least a portion of the information corresponding to the target resource is all of the information corresponding to the target resource.

[0122] For example, if a target resource corresponds to three HARQ-ACK bits and the corresponding Uu priority values ​​are 1, 1, and 0 respectively, then the Uu priority value of the target resource is 1 or 0.

[0123] (2) A Uu priority value corresponding to a specific SL priority value among the SL priority values ​​of at least a portion of the information corresponding to the target resource. The specific SL priority value may be a Uu priority value corresponding to the highest or lowest SL priority value among the SL priority values ​​of the information corresponding to the target resource.

[0124] Preferably, the at least a portion of the information corresponding to the target resource is all of the information corresponding to the target resource.

[0125] For example, if a target resource corresponds to three HARQ-ACK bits, and the corresponding SL priority values ​​are 1, 1, and 8, and the Uu priority value corresponding to 1 is 1, then the Uu priority value of the target resource is 1.

[0126] (3) A Uu priority value of at least a portion of the information corresponding to the target resource. Preferably, the at least a portion of the information corresponding to the target resource is all of the information corresponding to the target resource.

[0127] For example, if a target resource corresponds to three HARQ-ACK bits and the corresponding Uu priority values ​​are 1, 1, and 0 respectively, then the Uu priority values ​​of the target resource include 1 and 0.

[0128] It should be noted that in the embodiment of the present application, the correspondence between the priority value and the priority may be in a forward order or in a reverse order, where the forward order means that the higher the priority value, the higher the priority, and the reverse order means that the higher the priority value, the lower the priority. The above example is described in terms of the reverse order, and it can be understood that the same applies to the forward order. When corresponding to the forward order, a priority value higher than another priority value described in the present invention is replaced by a priority value lower than another priority value accordingly, and / or a priority value lower than another priority value is described, and the other priority value is replaced by a priority value lower than another priority value accordingly. Higher than can be replaced by.

[0129] In some embodiments, the target resource includes one or more of the following (1) to (4):

[0130] (1) A resource on which a target object resides, which may be, for example, an SL resource or a Uu resource, and which includes an SL channel, an SL signal, SL signaling, SL information, and / or an SL message. For example, the SL information is a SL HARQ-ACK.

[0131] (2) Uu channels, signals, and / or resources for transmitting or indicating targeted content, where the targeted content includes SL signals, SL signaling, SL information, and / or SL messages. The above transmission includes forwarding, conveying, transporting, reporting, and the like. For example, a PUCCH and / or a PUSCH carrying a SL HARQ-ACK, or a PUCCH carrying a SL SR, or a PUCCH and / or a PUSCH carrying SL channel state information (CSI).

[0132] (3)SL HARQ-ACK.

[0133] (4) Uplink resources (PUCCH and / or PUSCH) on which SL HARQ-ACK is carried.

[0134] In some embodiments, information corresponding to a target resource may be at least one of: (1) information that is to be, will be, or may be transferred, conveyed, transported, and / or reported at the target resource; and (2) information associated with the target resource.

[0135] In some embodiments, the target resource not having the first Uu priority may be specifically interpreted as at least one of the following (1) and (2).

[0136] (1) The network side does not schedule, set or indicate the first Uu priority of the target resource. Specifically, in some embodiments, the control signaling (e.g., DCI, MAC CE and / or RRC) that schedules, configures or indicates the first resource does not include priority indication information (e.g., priority indicator and / or phy-PriorityIndex).

[0137] (2) The first Uu priority of the target resource is not predefined or preconfigured. The following describes the manner of determining target transmission under various conditions, and in some embodiments, after determining the target transmission, the target transmission is performed in the first resource. In the following, the target transmission is performed in the first resource as an example.

[0138] 1. The target resource has a first Uu priority and the first resource has a second Uu priority, and determining the target transmission includes at least one of the following (1) and (2): (1) determining a first Uu priority;

[0139] (1) When the first Uu priority of the target resource and the second Uu priority of the first resource are the same or the difference value is smaller than a first predetermined difference value, at least a portion of the information corresponding to the target resource can be transmitted in the first resource, that is, multiplexed and transmitted only when the Uu priorities are the same.

[0140] Specifically, when the first Uu priority of the target resource and the second Uu priority of the first resource are the same and have the first priority, transmit at least a part of the information corresponding to the target resource in the first resource.

[0141] Optionally, this case may be combined with the above-mentioned Case 1 in which the first Uu priority is determined based on the first SL priority, or may be combined with Case 2 and Case 3 in which the first Uu priority is determined based on the first SL priority.

[0142] Specifically, when the first Uu priority of the target resource and the second Uu priority of the first resource are the same and have the second priority, transmit at least a part of the information corresponding to the target resource in the first resource.

[0143] Optionally, this case may be combined with the above-mentioned Case 2 in which the first Uu priority is determined based on the first SL priority, or may be combined with Case 1 and Case 3 in which the first Uu priority is determined based on the first SL priority.

[0144] (2) When the first Uu priority of the target resource and the second Uu priority of the first resource are different, or the difference value is greater than a second predetermined difference value, at least some of the information corresponding to the target resource is not transmitted in the first resource, that is, when the Uu priorities are different, multiplexing and transmission is not possible.

[0145] Specifically, when the first Uu priority of the target resource is the first priority and the second Uu priority of the first resource is the second priority, at least a part of the information corresponding to the target resource is not transmitted in the first resource.

[0146] This case may be combined with the above-mentioned Case 1 in which the first Uu priority is determined based on the first SL priority, or with Case 2 and Case 3 in which the first Uu priority is determined based on the first SL priority.

[0147] Specifically, when the first Uu priority of the target resource is the second priority and the second Uu priority of the first resource is the first priority, at least a part of the information corresponding to the target resource is not transmitted in the first resource.

[0148] This case may be combined with the above-mentioned Case 2 in which the first Uu priority is determined based on the first SL priority, or may be combined with Case 1 and Case 3 in which the first Uu priority is determined based on the first SL priority.

[0149] Furthermore, when the first Uu priority of the target resource is different from the second Uu priority of the first resource, the target resource or the first resource is transmitted according to the Uu priority.

[0150] Specifically, when the first Uu priority of the target resource is different from the second Uu priority of the first resource, the one with the higher Uu priority is transmitted. For example, when the Uu priority corresponding to the target resource is high priority, or priority high, or priority index 1, and the Uu priority corresponding to the first resource is low priority, or priority low, or priority index 0, the target resource is transmitted.

[0151] If the Uu priority corresponding to the target resource is low priority, or priority low, or priority index 0, and the Uu priority corresponding to the first resource is high priority, or priority high, or priority index 1, then transmit the first resource.

[0152] What should be noted is that the higher Uu priority is transmitted while the lower Uu priority is discarded.

[0153] 2. The target resource has a first Uu priority, and the first resource has or does not have a second Uu priority, i.e., in this case, regardless of whether the first resource has the second Uu priority, determining the target transmission includes at least one of the following (1) and (2).

[0154] (1) If a first Uu priority of the target resource is equal to or greater than a first specific priority and / or equal to or less than a second specific priority, transmit at least a portion of information corresponding to the target resource in the first resource.

[0155] (2) When the first Uu priority of the target resource is equal to or higher than the third specific priority and / or equal to or lower than the fourth specific priority, at least a part of information corresponding to the target resource is not transmitted in the first resource.

[0156] That is, if the Uu priority of the target resource does not meet the requirement, multiplexing and transmission is not possible.

[0157] Optionally, at least some of the first specific priority, the second specific priority, the third specific priority, and the fourth specific priority may be priorities corresponding to sl-PriorityThresholdULURLLC and / or sl-PriorityThreshold, for example Uu priorities corresponding to sl-PriorityThresholdULURLLC and / or sl-PriorityThreshold.

[0158] In the present invention, the priority corresponding to sl-PriorityThresholdULURLLC and / or sl-PriorityThreshold is the Uu priority or SL priority corresponding to sl-PriorityThresholdULURLLC and / or sl-PriorityThreshold. In one embodiment, sl-PriorityThresholdULURLLC and / or sl-PriorityThreshold is a priority value, and the SL priority corresponding to sl-PriorityThresholdULURLLC and / or sl-PriorityThreshold is the SL priority corresponding to said value. In one embodiment, the Uu priority corresponding to sl-PriorityThresholdULURLLC and / or sl-PriorityThreshold may be interpreted as the Uu priority corresponding to the SL priority corresponding to sl-PriorityThresholdULURLLC and / or sl-PriorityThreshold.

[0159] 3. The target resource has or does not have a first Uu priority, and the first resource has a second Uu priority, i.e., in this case, it does not matter whether the target resource has the first Uu priority, and it does not matter whether the Uu priority of the target resource is defined, where this may be combined with case 1 / 2 / 3 of determining the first Uu priority based on the first SL priority, or it may operate without the Uu priority of the target resource being defined, and determining the target transmission includes at least one of the following (1) and (2).

[0160] (1) When the second Uu priority of the first resource is the first priority, at least a part of the information corresponding to the target resource is not transmitted in the first resource.

[0161] (2) When the second Uu priority of the first resource is the second priority, transmit at least a portion of the information corresponding to the target resource in the first resource.

[0162] Here, the first priority is higher than the second priority.

[0163] That is, 1R The sources and / or their corresponding information can only be multiplexed and transmitted when they have low priority or priority low or priority index 0 or eMBB.

[0164] 4. The target resource has or does not have a first Uu priority, and the first resource has a second Uu priority, i.e., in this case, it does not matter whether the target resource has the first Uu priority, and it does not matter whether the Uu priority of the target resource is defined. Here, it may be combined with the above case 1 / 2 / 3 of determining the first Uu priority based on the first SL priority, and may operate without defining the Uu priority of the target resource, and determining the target transmission includes at least one of the following (1) and (2).

[0165] (1) When the second Uu priority of the first resource is the first priority, transmit at least a portion of the information corresponding to the target resource in the first resource.

[0166] (2) When the second Uu priority of the first resource is the second priority, at least a part of the information corresponding to the target resource is not transmitted in the first resource.

[0167] Here, the first priority is higher than the second priority.

[0168] That is, the first Uu resource and / or its corresponding information can be multiplexed and transmitted only when it has high priority or priority high or priority index 1 or URLLC.

[0169] 5. Determining the target transmission includes at least one of: (1) transmitting at least a portion of information corresponding to the target resource on a first resource; (2) transmitting at least a portion of information corresponding to the target resource on the first resource if a first SL priority of the target resource is equal to or greater than a fifth specific priority and / or equal to or less than a sixth specific priority; and (3) transmitting at least a portion of information corresponding to the target resource on the first resource if a first SL priority of the target resource is equal to or greater than a seventh specific priority and / or equal to or less than an eighth specific priority.

[0170] Optionally, at least a portion of the fifth to eighth specific priorities may be SL priorities corresponding to sl-PriorityThresholdULURLLC and / or sl-PriorityThreshold.

[0171] For example, if the first SL priority of the target resource is greater than or equal to the SL priority corresponding to sl-PriorityThresholdURLLC or sl-PriorityThreshold, then at least a portion of the information corresponding to the target resource may be transmitted.

[0172] Furthermore, if the first resource has a first priority, at least a portion of the information corresponding to the target resource may be transmitted if the first SL priority of the target resource is equal to or greater than the SL priority corresponding to sl-PriorityThresholdULURLLC or sl-PriorityThreshold.

[0173] For example, if the first SL priority of the target resource is less than or equal to the SL priority corresponding to sl-PriorityThreshold or sl-PriorityThresholdURLLC, at least a portion of the information corresponding to the target resource may be transmitted.

[0174] Furthermore, if the first resource has a second priority, at least a portion of the information corresponding to the target resource may be transmitted if the first SL priority of the target resource is less than or equal to the SL priority corresponding to sl-PriorityThreshold or sl-PriorityThresholdURLLC.

[0175] Example 1. The target resource is a PUCCH for transmitting a SL HARQ-ACK, and the first resource is a PUSCH, in which case includes at least one of the following i and ii:

[0176] i. The SL HARQ-ACK is multiplexed into the PUSCH only when the SL priority value of the SL HARQ-ACK is equal to or greater than the priority value corresponding to sl-PriorityThreshold or sl-PriorityThresholdULURLLC, or the SL HARQ-ACK is multiplexed into the PUSCH only when the SL priority of the SL HARQ-ACK is equal to or less than the priority value corresponding to sl-PriorityThreshold or sl-PriorityThresholdULURLLC.

[0177] ii. The SL HARQ-ACK is multiplexed onto the PUSCH only if its SL priority value is less than or equal to the priority value corresponding to sl-PriorityThresholdULURLLC or sl-PriorityThreshold, or the SL HARQ-ACK is multiplexed onto the PUSCH only if its SL priority is greater than or equal to the priority value corresponding to sl-PriorityThresholdULURLLC or sl-PriorityThreshold.

[0178] Example 2. i. The SL HARQ-ACK is multiplexed onto the PUSCH only when the first resource is low priority, or priority low, or priority index 0, or eMBB, and the SL priority value of the SL HARQ-ACK is equal to or greater than the priority value corresponding to the sl-PriorityThreshold, or the SL HARQ-ACK is multiplexed onto the PUSCH only when the SL priority of the SL HARQ-ACK is equal to or less than the priority value corresponding to the sl-PriorityThreshold.

[0179] ii. The SL HARQ-ACK is multiplexed onto the PUSCH only when the first resource is low priority, or priority low, or priority index 0, or eMBB, and the SL priority value of the SL HARQ-ACK is equal to or greater than the priority value corresponding to sl-PriorityThresholdULURLLC, or the SL HARQ-ACK is multiplexed onto the PUSCH only when the SL priority of the SL HARQ-ACK is equal to or less than the priority value corresponding to sl-PriorityThresholdULURLLC.

[0180] iii. If the priority of the first resource is high priority, or priority high, or priority index 1, or URLLC, the SL HARQ-ACK is multiplexed into the PUSCH only when the SL priority value of the SL HARQ-ACK is equal to or less than the priority value corresponding to sl-PriorityThresholdULURLLC, or the SL HARQ-ACK is multiplexed into the PUSCH only when the SL priority of the SL HARQ-ACK is equal to or greater than the priority value corresponding to sl-PriorityThresholdULURLLC.

[0181] v. If the priority of the first resource is high priority, or priority high, or priority index 1, or URLLC, the SL HARQ-ACK is multiplexed into the PUSCH only when the SL priority value of the SL HARQ-ACK is equal to or less than the priority value corresponding to the sl-PriorityThreshold, or the SL HARQ-ACK is multiplexed into the PUSCH only when the SL priority of the SL HARQ-ACK is equal to or greater than the priority value corresponding to the sl-PriorityThreshold.

[0182] It should be noted that at least some of the information herein and at least some of the information mentioned in determining the target transmission based on the associated priority described above may be different objects or may be the same object.

[0183] 6. If the first resource has a second Uu priority and / or the first control signaling is equipped with priority indication information (e.g., priority indicator and / or phy-PriorityIndex), transmit at least some information corresponding to the target resource in the first resource, where the first control signaling is for scheduling, configuring or indicating the first resource, e.g., DCI, MAC CE and / or RRC.

[0184] 7. If the first resource does not have a second Uu priority and / or the first control signaling does not carry priority indication information (e.g., priority indicator and / or phy-PriorityIndex), transmit at least some information corresponding to the target resource in the first resource, where the first control signaling is for scheduling, configuring or indicating the first resource, e.g., DCI, MAC CE and / or RRC.

[0185] Furthermore, when transmitting at least a portion of the information corresponding to the target resource in the first resource, the at least a portion of the information includes at least one of the following (a) to (l):

[0186] (a) All information corresponding to the target resource, that is, all information corresponding to the target resource can be transmitted in the first resource.

[0187] (b) Information of the same priority as the second Uu priority of the first resource. In other words, it is possible to transmit information of the same priority as the Uu priority corresponding to the first resource among the information corresponding to the target resource in the first resource. For example, if the first resource is high priority or priority high or priority index 1 or URLLC, information corresponding to high priority or priority high or priority index 1 or URLLC among information corresponding to the target resource can be transmitted. Also, for example, when the first resource is low priority or priority low or priority index 0 or eMBB, information corresponding to low priority or priority low or priority index 0 or eMBB among information corresponding to the target resource can be transmitted.

[0188] (c) Information of second Uu priority or higher for the first resource. For example, if the first resource is high priority or priority high or priority index 1 or URLLC, information corresponding to high priority or priority high or priority index 1 or URLLC among information corresponding to the target resource can be transmitted. For example, when the first resource is low priority or priority low or priority index 0 or eMBB, among the information corresponding to the target resource, information corresponding to low priority or priority low or priority index 0 or eMBB and information corresponding to high priority or priority high or priority index 1 or URLLC can be transmitted.

[0189] (d) Information of the first resource below the second Uu priority. For example, when the first resource is high priority or priority high or priority index 1 or URLLC, among information corresponding to the target resource, information corresponding to low priority or priority low or priority index 0 or eMBB and information corresponding to high priority or priority high or priority index 1 or URLLC can be transmitted. Also, for example, when the first resource is low priority or priority low or priority index 0 or eMBB, information corresponding to low priority or priority low or priority index 0 or eMBB among information corresponding to the target resource can be transmitted.

[0190] (e) The corresponding first SL priority is higher than the sixth predetermined priority.

[0191] (f) Information whose corresponding first SL priority value is lower than a sixth predetermined priority value.

[0192] (g) The corresponding first Uu priority is higher than the seventh predetermined priority.

[0193] (h) Information whose corresponding first Uu priority value is lower than the seventh predetermined priority value.

[0194] (i) The corresponding first SL priority is lower than the eighth predetermined priority.

[0195] (j) Information whose corresponding first SL priority value is higher than an eighth predetermined priority value.

[0196] (k) The corresponding first Uu priority is lower than the ninth predetermined priority.

[0197] (l) Information whose corresponding first Uu priority value is higher than the ninth predetermined priority value.

[0198] The sixth to ninth predetermined priorities (values) may be the same or different. Optionally, at least some of the sixth to ninth predetermined priorities may correspond to a priority corresponding to sl-PriorityThresholdULURLLC and / or a priority corresponding to sl-PriorityThreshold. For example, at least some of the sixth to ninth predetermined priorities may correspond to an SL priority corresponding to sl-PriorityThresholdULURLLC, an SL priority corresponding to sl-PriorityThreshold, a Uu priority corresponding to sl-PriorityThresholdULURLLC and / or a Uu priority corresponding to sl-PriorityThreshold.

[0199] Furthermore, when at least a portion of the information corresponding to the target resource is not transmitted in the first resource, the at least a portion of the information includes at least one of the following (a) to (l):

[0200] (a) It is not possible to transmit all the information corresponding to the target resource, that is, all the information corresponding to the target resource in the first resource.

[0201] (b) It is not possible to transmit information of a priority different from the second Uu priority of the first resource, i.e., information corresponding to the target resource in the first resource that has a priority different from the Uu priority corresponding to the first Uu resource. For example, if the first resource is high priority or priority high or priority index 1 or URLLC, information corresponding to the target resource that is low priority or priority low or priority index 0 or eMBB cannot be transmitted. Also, for example, when the first resource is low priority or priority low or priority index 0 or eMBB, information corresponding to high priority or priority high or priority index 1 or URLLC among information corresponding to the target resource cannot be transmitted.

[0202] (c) Information of second Uu priority or higher for the first resource. For example, if the first Uu resource is high priority or priority high or priority index 1 or URLLC, information corresponding to the target resource, among information corresponding to high priority or priority high or priority index 1 or URLLC, cannot be transmitted. Also, for example, if the first Uu resource is low priority or priority low or priority index 0 or eMBB, among the information corresponding to the target resource, information corresponding to low priority or priority low or priority index 0 or eMBB and information corresponding to high priority or priority high or priority index 1 or URLLC cannot be transmitted.

[0203] (d) Information of the first resource below the second Uu priority. For example, if the first Uu resource is high priority or priority high or priority index 1 or URLLC, among the information corresponding to the target resource, information corresponding to low priority or priority low or priority index 0 or eMBB and information corresponding to high priority or priority high or priority index 1 or URLLC cannot be transmitted. Also, for example, when the first Uu resource is low priority or priority low or priority index 0 or eMBB, information corresponding to the target resource that corresponds to low priority or priority low or priority index 0 or eMBB cannot be transmitted.

[0204] (e) The corresponding first SL priority is lower than the tenth predetermined priority.

[0205] (f) Information whose corresponding first SL priority value is higher than a tenth predetermined priority value.

[0206] (g) The corresponding first Uu priority is lower than the eleventh predetermined priority.

[0207] (h) Information in which the corresponding first Uu priority value is higher than an eleventh predetermined priority value.

[0208] (i) The corresponding first SL priority is higher than the twelfth predetermined priority.

[0209] (j) Information whose corresponding first SL priority value is lower than a twelfth predetermined priority value.

[0210] (k) The corresponding first Uu priority is higher than the thirteenth predetermined priority.

[0211] (l) Information whose corresponding first Uu priority value is lower than a thirteenth predetermined priority value.

[0212] The tenth to thirteenth predetermined priorities (values) may be the same or different. Optionally, at least some of the tenth to thirteenth predetermined priorities may correspond to a priority corresponding to sl-PriorityThresholdULURLLC and / or a priority corresponding to sl-PriorityThreshold. Optionally, at least some of the tenth to thirteenth predetermined priorities may correspond to an SL priority corresponding to sl-PriorityThresholdULURLLC, an SL priority corresponding to sl-PriorityThreshold, a Uu priority corresponding to sl-PriorityThresholdULURLLC and / or a Uu priority corresponding to sl-PriorityThreshold.

[0213] It can be understood that if the transmitted information is a portion of all the information corresponding to the target resource, or is not all the information corresponding to the target resource, information other than at least a portion of the information is dropped.

[0214] In some embodiments, the target resource includes multiple Uu priorities, and / or the information corresponding to the target resource corresponds to different Uu priorities, and when multiple first resources overlap with the target resource or meet a collision condition or meet a multiplexing condition, the method further includes determining a target transmission based on a second Uu priority of each first resource.

[0215] Specifically, according to the method for each case described above, each first resource is considered and a target transmission is determined.

[0216] For example, information corresponding to a certain Uu priority is multiplexed into a first Uu resource corresponding to the same Uu priority.

[0217] Specifically, for example, when a target resource PUCCH corresponds to two sidelink HARQ-ACK bits, the corresponding Uu priorities are high and low, respectively, and the target resource overlaps with two PUSCHs with Uu priorities high and low, the corresponding sidelink HARQ-ACK bit with high Uu priority is multiplexed onto the PUSCH with high Uu priority, and the corresponding sidelink HARQ-ACK bit with low Uu priority is multiplexed onto the PUSCH with low Uu priority.

[0218] In some embodiments, when a plurality of first resources overlap with the target resource, or meet a collision condition, or meet a multiplexing condition, the method further includes the following (1) and (2).

[0219] (1) Determine a target transmission based on the second Uu priority of each first resource according to a predetermined order, where the predetermined order includes a time domain order of the plurality of first resources, such as a time domain resource before-and-after order, which may be specifically before-and-after a time domain start point or before-and-after an end point, a frequency domain order of the plurality of first resources, an identifier order of the plurality of first resources, and / or a second Uu priority order of the plurality of first resources.

[0220] (2) Determine a target transmission based on a second specific Uu priority among the second Uu priorities.

[0221] For example, among the multiple first resources, the first resource with the highest Uu priority, the lowest Uu priority, a priority higher than threshold 1, or a priority lower than threshold 2 is considered to determine the target transmission.

[0222] In some embodiments, the priority of the target transmission is any one of the second Uu priority of the first resource, the first Uu priority of the target resource, and the first SL priority of the target resource.

[0223] Furthermore, if the priority of the target transmission is the second Uu priority of the first resource, the second Uu priority of the first resource is higher than the first Uu priority or the first SL priority of the target resource.

[0224] Or, when the priority of the target transmission is the first Uu priority or the first SL priority of the target resource, the first Uu priority or the first SL priority of the target resource is higher than the second Uu priority of the first resource.

[0225] Similarly, in some embodiments, the priority value of the target transmission is any one of the second Uu priority value of the first resource, the first Uu priority value of the target resource, and the first SL priority value of the target resource.

[0226] Furthermore, when the priority value of the target transmission is the second Uu priority value of the first resource, the second Uu priority value of the first resource is lower than the first Uu priority value or the first SL priority value of the target resource.

[0227] Or, when the priority value of the target transmission is the first Uu priority value or the first SL priority value of the target resource, the first Uu priority value or the first SL priority value of the target resource is lower than the second Uu priority value of the first resource.

[0228] In some embodiments, the first resource is a PUCCH and / or PUSCH resource, for example, a PUCCH and / or PUSCH having Uu priority. For example, the first resource may be a PUCCH and / or PUSCH corresponding to information having Uu priority, and may also be other uplink signals, for example, uplink reference signals. Specifically, SRS and Positioning RS are included.

[0229] 3, an embodiment of the present application provides a priority definition method applied to a communication device, which can be a terminal or a network side device, and the method includes the following steps 301 and 302:

[0230] In step 301, a mapping relationship between a first Uu priority and a first SL priority of a target resource is set or obtained.

[0231] It should be noted that when the executing communication device is a network side device (e.g., a base station), this step is to set a mapping relationship between the first Uu priority and the first SL priority of the target resource, and when the executing communication device is a terminal, this step is to obtain a mapping relationship between the first Uu priority and the first SL priority of the target resource, which may be done, for example, by base station setting, protocol pre-definition, pre-setting, user customization, etc.

[0232] In step 302, a first Uu priority of the target resource is determined based on the mapping relationship.

[0233] The above mapping relationship may be understood as a correspondence relationship between the first SL priority and the first Uu priority.

[0234] It should be noted that the above mapping relationship may include cases where different first SL priorities correspond to different first Uu priorities, and may also include cases where the first Uu priorities are defined as the same priority regardless of the first SL priority of the target resource, for example, all are defined as first priority or second priority.

[0235] In the embodiment of the present application, the target resource is associated with SL, and being associated with SL means that the target resource may be an SL resource, or may be a Uu resource for transmitting SL-related information.

[0236] The first Uu priority of the target resource includes a Uu priority of the target resource and / or a Uu priority of at least some information corresponding to the target resource, and the first SL priority of the target resource includes a SL priority of the target resource and / or a SL priority of at least some information corresponding to the target resource.

[0237] In some embodiments, the mapping relationship satisfies that the first Uu priority of the target resource is a specific priority, or when the first SL priority of the target resource satisfies a specific condition, the first Uu priority of the target resource is a specific priority corresponding to the specific condition.

[0238] In an embodiment of the present application, a Uu priority corresponding to or equivalent to the SL priority is predefined for the target resource, that is, a mapping relationship between the first Uu priority and the first SL priority of the target resource is established, and the first Uu priority of the target resource can be determined according to the predefined mapping relationship by the first SL priority of the target.

[0239] Furthermore, the first Uu priority of the target resource is a specific priority, or if the first SL priority of the target resource meets a specific condition, the first Uu priority of the target resource is a specific priority.

[0240] In an embodiment of the present application, when determining the first Uu priority based on the first SL priority, a unified specific priority may be adopted for all various first SL priorities, or the first Uu priority may be determined to be a specific priority corresponding to a specific condition that the first SL priority satisfies.

[0241] The above specific priority may include one or more priorities, such as, for example, high, medium, and low priority, or, for example, priorities 1, 2, 3, 4, and 5, and the embodiments of the present application do not specifically limit the types of priorities included in the specific priority.

[0242] Accordingly, the specific condition also includes one or more conditions, that is, different specific conditions correspond to different specific priorities.

[0243] Below, a scene in which a specific priority includes two types of priority will be described as an example.

[0244] Specifically, the specific priority includes at least one of a first priority and a second priority.

[0245] The above first priority may be interpreted as high priority, or priority high, or priority index 1, or URLLC, and when the first Uu priority of the target resource and / or at least some information corresponding thereto is the first priority, the target resource and / or at least some information corresponding thereto may be understood to be high priority, or priority high, or priority index 1, or URLLC. For example, the first priority may correspond to a URLLC service, in which case, selectively, the target resource and / or the information corresponding thereto is considered to be URLLC, and the first Uu priority of the target resource corresponds to the priority of URLLC.

[0246] The second priority may be interpreted as low priority, or priority low, or priority index 0, or eMBB, and when the first Uu priority of the target resource and / or at least some information corresponding thereto is the second priority, the target resource and / or at least some information corresponding thereto may be understood as low priority, or priority low, or priority index 0, or eMBB. For example, the second priority may correspond to an eMBB service, in which case, selectively, the target resource and / or the information corresponding thereto is eMBB, and the first Uu priority of the target resource is considered to correspond to the priority of eMBB.

[0247] Determining the first Uu priority of the target resource based on the first SL priority of the target resource may include the following Case 1 and Case 2.

[0248] In Case 1, the first Uu priority of the target resource is determined as the first priority.

[0249] In Case 2, the first Uu priority of the target resource is determined as the second priority.

[0250] Specifically, the specific condition includes at least one of a first condition and a second condition.

[0251] Determining the first Uu priority of the target resource based on the first SL priority of the target resource may further include the following Case 3.

[0252] In Case 3, if the first SL priority of the target resource satisfies the first condition, the first Uu priority of the target resource is set as the first priority, and / or, if the first SL priority of the target resource satisfies the second condition, the first Uu priority of the target resource is set as the second priority.

[0253] Further, the first condition includes one or more of: the first SL priority of the target resource is greater than or equal to the first predetermined priority; the first SL priority value of the target resource is less than or equal to the first predetermined priority value; the second predetermined priority and / or the second predetermined priority value has not been set or obtained; and the second condition is not satisfied.

[0254] The second condition includes one or more of: the first SL priority of the target resource is equal to or greater than a third predetermined priority; the first SL priority value of the target resource is equal to or less than the third predetermined priority value; the fourth predetermined priority and / or the fourth predetermined priority value has not been set or obtained; the first SL priority of the target resource is equal to or less than a fifth predetermined priority; and the first SL priority value of the target resource is equal to or greater than a fifth predetermined priority value, and in one selectable embodiment, the fifth priority is the first priority; and the first condition is not satisfied.

[0255] What should be noted is that at least some of the first to fifth predetermined priorities may correspond to priorities corresponding to sl-PriorityThresholdULURLLC and / or sl-PriorityThreshold, and at least some of the first to fifth predetermined priority values ​​may correspond to priority values ​​corresponding to sl-PriorityThresholdULURLLC and / or sl-PriorityThreshold.

[0256] It should be noted that the first to fifth predetermined priorities (values) may be the same or different, and the embodiments of the present application are not specifically limited thereto.

[0257] Based on the same principle, when a specific priority includes three types of priorities, namely, high, medium, and low, determining the first Uu priority based on the first SL priority may include: (1) setting the first Uu priority as a high priority; (2) setting the first Uu priority as a medium priority; (3) setting the first Uu priority as a low priority; (4) setting the first Uu priority as a high priority if the first SL priority satisfies a first condition; (5) setting the first Uu priority as a medium priority if the first SL priority satisfies a second condition; and (6) setting the first Uu priority as a low priority if the first SL priority satisfies a third condition (the specific content of the third condition may be set by referring to the first and second conditions). For specific priorities of other priority types, a method of determining the first Uu priority based on the first SL priority may be set based on the same principle, and detailed explanation will be omitted.

[0258] In some embodiments, the first Uu priority of the target resource includes one or more of the following (1) to (3):

[0259] (1) A first specific Uu priority among Uu priorities of at least a portion of information corresponding to the target resource. The first specific Uu priority may be the highest or lowest Uu priority among the Uu priorities of the information corresponding to the target resource.

[0260] Preferably, the at least a portion of the information corresponding to the target resource is all of the information corresponding to the target resource.

[0261] For example, if a target resource corresponds to three HARQ-ACK bits and the corresponding Uu priorities are high, low, and high respectively, the Uu priority of the target resource is high or low.

[0262] (2) A Uu priority corresponding to a specific SL priority among the SL priorities of at least a portion of information corresponding to the target resource. The specific SL priority may be a Uu priority corresponding to the highest or lowest SL priority among the SL priorities of the information corresponding to the target resource.

[0263] Preferably, the at least a portion of the information corresponding to the target resource is all of the information corresponding to the target resource.

[0264] For example, if a target resource corresponds to three HARQ-ACK bits, and the corresponding SL priorities are SL priorities corresponding to priority values ​​1, 1, and 8 respectively, and the Uu priority corresponding to the SL priority value 1 is high, then the Uu priority of the target resource is high.

[0265] (3) Uu priority of at least some of the information corresponding to the target resource. For example, if a target resource corresponds to three HARQ-ACK bits and the corresponding Uu priorities are high / low / high respectively, the Uu priorities of the target resource include high and low.

[0266] Similarly, the first Uu priority value of the target resource includes one or more of the following (1) to (3):

[0267] (1) A first specific Uu priority value among the Uu priority values ​​of at least a portion of the information corresponding to the target resource. The first specific Uu priority value may be the highest or lowest Uu priority value among the Uu priority values ​​of information corresponding to the target resource.

[0268] Preferably, the at least a portion of the information corresponding to the target resource is all of the information corresponding to the target resource.

[0269] For example, if a target resource corresponds to three HARQ-ACK bits and the corresponding Uu priority values ​​are 1, 1, and 0 respectively, then the Uu priority value of the target resource is 1 or 0.

[0270] (2) A Uu priority value corresponding to a specific SL priority value among the SL priority values ​​of at least a portion of the information corresponding to the target resource. The specific SL priority value may be a Uu priority value corresponding to the highest or lowest SL priority value among the SL priority values ​​of the information corresponding to the target resource.

[0271] Preferably, the at least a portion of the information corresponding to the target resource is all of the information corresponding to the target resource.

[0272] For example, if a target resource corresponds to three HARQ-ACK bits, and the corresponding SL priority values ​​are 1, 1, and 8, and the Uu priority value corresponding to 1 is 1, then the Uu priority value of the target resource is 1.

[0273] (3) A Uu priority value of at least a portion of the information corresponding to the target resource. Preferably, the at least a portion of the information corresponding to the target resource is all of the information corresponding to the target resource.

[0274] For example, if a target resource corresponds to three HARQ-ACK bits and the corresponding Uu priority values ​​are 1, 1, and 0 respectively, then the Uu priority values ​​of the target resource include 1 and 0.

[0275] It should be noted that in the embodiment of the present application, the correspondence between the priority value and the priority may be in a forward order or in a reverse order. The forward order means that the higher the priority value, the higher the priority, and the reverse order means that the higher the priority value, the lower the priority. The above example is described in terms of the reverse order, and it can be understood that the same applies to the forward order.

[0276] In some embodiments, the target resource includes one or more of the following (1) to (4):

[0277] (1) A resource on which a target object resides, which may be, for example, an SL resource, including an SL channel, an SL signal, SL signaling, SL information, and / or an SL message. For example, the SL information is a SL HARQ-ACK.

[0278] (2) Uu channels, signals, and / or resources for transmitting or indicating targeted content, where the targeted content includes SL signals, SL signaling, SL information, and / or SL messages. The above transmission includes forwarding, conveying, transporting, reporting, and the like. For example, PUCCH and / or PUSCH equipped with SL HARQ-ACK, or PUCCH equipped with SL SR, or PUCCH and / or PUSCH equipped with SL CSI.

[0279] (3)SL HARQ-ACK.

[0280] (4) Uplink resources (PUCCH and / or PUSCH) on which SL HARQ-ACK is carried.

[0281] In some embodiments, information corresponding to the target resource may be at least one of: (1) information that is scheduled or may be transferred, conveyed, carried, and / or reported at the target resource; and (2) information associated with the target resource.

[0282] The methods provided in the present application are described below in conjunction with specific examples.

[0283] In the following examples, the SL PUCCH is the PUCCH on which SL related information (eg, SL HARQ-ACK) is carried.

[0284] Example 1 It is not possible to multiplex with different priorities. Alternatively, if a UuPUSCH having a low priority, or priority low, or priority index 0, or eMBB, and a SL PUCCH having a high priority, or priority high, or priority index 1, or URLLC, overlap, or meets a collision condition, or meets a multiplexing condition, the SL HARQ-ACK on the SL PUCCH cannot be multiplexed onto the PUSCH.

[0285] Alternatively, if a UuPUSCH having a high priority, or priority high, or priority index 1, or URLLC, and a SL PUCCH having a low priority, or priority low, or priority index 0, or eMBB, overlap, or meet a collision condition, or meet a multiplexing condition, the SL HARQ-ACK on the SL PUCCH cannot be multiplexed onto the PUSCH.

[0286] Second embodiment Multiplexing with the same priority is possible. Alternatively, if a UuPUSCH having a high priority, or priority high, or priority index 1, or URLLC, and a SL PUCCH having a high priority, or priority high, or priority index 1, or URLLC, overlap, or satisfy a collision condition, or satisfy a multiplexing condition, the SL HARQ-ACK on the SL PUCCH can be multiplexed into the PUSCH.

[0287] Alternatively, if a UuPUSCH having a low priority, or priority low, or priority index 0, or eMBB, and a SL PUCCH having a low priority, or priority low, or priority index 0, or eMBB overlap, or satisfy a collision condition, or satisfy a multiplexing condition, the SL HARQ-ACK on the SL PUCCH can be multiplexed into the PUSCH.

[0288] Third Embodiment A PUSCH with no priority specified, low priority, priority low, priority index 0, or eMBB can be multiplexed only in the PUSCH. Alternatively, if a UuPUSCH with a priority of no priority indicated or low priority, or priority low, or priority index 0, or eMBB overlaps with a SL PUCCH, or satisfies a collision condition, or satisfies a multiplexing condition, the SL HARQ-ACK on the SL PUCCH can be multiplexed onto a PUSCH with a priority of eMBB.

[0289] Alternatively, if a UuPUSCH with priority indicated or high priority, or priority high, or priority index 1, or URLLC overlaps with a SL PUCCH, or satisfies a collision condition, or satisfies a multiplexing condition, the SL HARQ-ACK on the SL PUCCH cannot be multiplexed into a PUSCH with priority indicated or high priority, or priority high, or priority index 1, or URLLC.

[0290] Example 4 SL HARQ-ACK can only be multiplexed onto low priority or priority low or priority index 0 or eMBB PUSCH, or PUSCH without priority (eg, PUSCH scheduled in DCI format and without a priority indicator field).

[0291] 4, an embodiment of the present application provides a transmission device 400 applied to a communication device, which may be a terminal or a network side device, and the transmission device 400 includes a first determination module 401 for determining a target transmission when a target resource and a first resource at least partially overlap, or meet a collision condition, or meet a multiplexing condition, where the target resource is associated with a sidelink SL, the target resource has or does not have a first Uu priority, the first resource has or does not have a second Uu priority, the first Uu priority of the target resource includes the Uu priority of the target resource and / or the Uu priority of at least some information corresponding to the target resource, the target resource has a first SL priority, and the first SL priority of the target resource includes the SL priority of the target resource and / or the sidelink SL priority of at least some information corresponding to the target resource.

[0292] In some embodiments, the first resource having the second Uu priority specifically means at least one of the following: the network side schedules, sets or indicates the second Uu priority of the first resource; and the second Uu priority of the first resource is predefined or pre-set.

[0293] In some embodiments, the first resource not having a second Uu priority specifically means at least one of the following: the network side has not scheduled, set or indicated the second Uu priority of the first resource; and the second Uu priority of the first resource has not been predefined or preconfigured.

[0294] In some embodiments, the first resource is used for at least one of URLLC transmissions, transmissions above a priority threshold, transmissions above a reliability requirement, transmissions below a delay threshold and where the packet delay budget PDB is less than a PDB threshold or the excess PDB is less than a excess PDB threshold, eMBB transmissions, transmissions below a priority threshold, transmissions below a reliability requirement, and transmissions above a delay threshold and where the PDB is greater than a PDB threshold or the excess PDB is greater than a excess PDB threshold.
