The base station is not limited to specific technical terms. It should be noted that in the embodiments of this application, only the base station in the NR system is used as an example, but the specific type of base station is not limited.

[0035] To better understand the solution provided in this application, the following will be described first:

[0036] sidelink transmission

[0037] Sidelink terminals can communicate with other terminals on the sidelink, which are typically vehicles, roadside units (RSUs), mobile phones, etc. that support Ssidelink technology.

[0038] The resource allocation modes for Vehicle-to-X (V2X) terminals are divided into:

[0039] First mode: The base station can schedule or control the terminal's transmission on the sidelink through the Uu interface and allocate corresponding resources to the terminal.

[0040] The second mode: the terminal acquires its own transmission resources on the sidelink, and some terminals may also be able to schedule transmissions of other V2X terminals on the sidelink.

[0041] Hybrid Automatic Repeat Request feedback (HARQfeedback) and reporting

[0042] To improve the reliability and resource utilization of data transmission on the sidelink, a HARQ feedback mechanism is introduced into sidelink technology. When a sidelink receiving user receives sidelink data (transmitted on the 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 the Physical Sidelink Control Channel (PSCCH) and / or PSSCH), it can indicate whether the sidelink transmission was successful or failed by sending a sidelink HARQ-ACK message. This sidelink HARQ-ACK is transmitted on the PSFCH resource. Upon receiving the sidelink HARQ-ACK message, the sidelink sending user can then determine whether the previous transmission was successful or failed. It is important to note that a single sidelink user can perform both receiving and transmitting operations at different times or in different frequency domains.

[0043] The transmission of sidelink packets may occur between the control node and the user (in which case the control node is operating on the sidelink), or it may occur on the sidelink between users. In the latter case, the control node may not be able to directly know whether the transmission of the sidelink packet was successful. The user needs to send the sidelink HARQACK information (such as sidelink ACK / NACK) to the control node via PUCCH or PUSCH so that the control node can further determine whether the transmission on the sidelink was successful.

[0044] The user who sends the sidelink HARQ-ACK information corresponding to a certain sidelink transmission to the base station is the sending user who sends this sidelink transmission. See [link to relevant documentation]. Figure 1 The figure shows an example of a sending user sending a sidelink HARQ-ACK message = NACK to the control node and an example of a receiving user responding with a sidelink HARQ-ACK message = NACK.

[0045] When the control node is a base station, the base station needs to allocate PUCCH or PUSCH resources for reporting sidelink HARQ-ACK information. The allocation of PUCCH or PUSCH resources is achieved by indicating the slot interval between PSFCH and PUCCH, PSFCH-PUCCH offset, in the Radio Resource Control (RRC) or Downlink Control Information (DCI) message.

[0046] sidelink physical channel priority

[0047] Different packets and services within a sidelink have different priorities, represented by values ​​from 1 to 8, with lower values ​​indicating higher priority. Specifically, the priority of sidelink data is indicated by the SCI (Service Control Interface), and the priority of the corresponding feedback resource PSFCH (Power Request Controller) is the same as the data's priority. A single PSFCH time-domain location may have multiple PSFCH resources, each potentially corresponding to different data. The priority of that PSFCH time-domain location is determined by the highest-priority PSFCH resource among these resources. The priority value of the S-SSB (Service-Side Block) can also be from 1 to 8, and its specific priority value can be configured or pre-configured.

[0048] Priority of PUCCH / PUSCH used for reporting sidelink HARQ-ACK

[0049] The base station can instruct PUCCH / PUSCH resources to report sidelink HARQ-ACKs to users. A PUCCH / PUSCH resource may be associated with one or more PSFCH time-domain locations. Before reporting sidelink HARQ-ACK information, the PUCCH / PUSCH resource will first sort and concatenate the sidelink HARQ-ACKs carried by at least some of the PSFCH resources in the associated PSFCH time-domain locations according to a certain order, and then send the sorted and concatenated sidelink HARQ-ACKs to the base station. That is, a PUCCH / PUSCH resource can correspond to one or more data sidelink HARQ-ACKs. In this case, the priority of the PUCCH / PUSCH resource is determined by the highest priority among the corresponding sidelink HARQ-ACKs.

[0050] Uu transmission and Uu HARQ-ACK priority

[0051] For downlink transmission, users will also provide HARQ-ACK feedback. Uu data is divided into two types: Enhanced Mobile Broadband (embb) and Ultra-reliable and Low Latency Communication (URLLC). Users will also support low-priority transmissions, such as priority low or priorityindex=0, and high-priority transmissions, such as priority high or priorityindex 1. The corresponding HARQ-ACK and data priorities are the same, 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.

[0052] PUCCH / PUSCH are used for HARQ-ACK transmission.

[0053] PUCCH can be used to transmit HARQ-ACK information. When PUCCH and PUSCH carrying HARQ-ACK information overlap, the user will not transmit PUCCH, but will multiplex the HARQ-ACK information that was originally to be transmitted on PUCCH onto PUSCH and transmit it together with the data part on PUSCH.

[0054] For Uu, in order to ensure the performance of high-priority transmission, in the existing technology, high-priority HARQ-ACK cannot be multiplexed on low-priority PUSCH; similarly, low-priority HARQ-ACK cannot be multiplexed on high-priority PUSCH.

[0055] If a PUSCH carrying low-priority or high-priority data overlaps with a PUCCH / PUSCH carrying sidelink HARQ-ACK, it is unclear whether and how the PUSCH can reuse the sidelink HARQ-ACK.

[0056] This is because the priority definitions for SL HARQ-ACK and the PUCCH / PUSCH carrying SL HARQ-ACK are different from those for DL ​​HARQ-ACK and the PUCCH / PUSCH carrying DL HARQ-ACK. They cannot be directly compared. For example, in SL priority, lower priority values ​​indicate higher priority, while in Uu priority, higher priority values ​​indicate higher priority. If sidelink HARQ-ACK is reused in a high-priority PUSCH such as URLLC, it may lead to decreased PUSCH reliability or increased latency. Conversely, if sidelink HARQ-ACK is not reused in a high-priority PUSCH such as URLLC, it may result in the loss of sidelink feedback.

[0057] To solve the above problems, see [link to relevant documentation]. Figure 2 This application provides a transmission method applied to a communication device, which may be a terminal or a network-side device. The method includes:

[0058] Step 201: When the target resource and the first resource have at least partial overlap, or meet the conflict condition or the reuse condition, determine the target transmission;

[0059] Among them, the target resource is related to SL, the target resource has or does not have the first Uu priority, and the first resource has or does not have the second Uu priority;

[0060] 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 first SL priority of the target resource includes: the SL priority of the target resource, and / or, the SL priority of at least some information corresponding to the target resource.

[0061] First, the following explanation is provided:

[0062] Uu priority refers to the priority system related to Uu, that is, the priority system related to Uu (priorityindex0, priorityindex1, etc.) is defined as Uu priority; SL priority refers to the priority system related to SL, that is, the priority system related to SL (such as priority values ​​1-8, etc.) is defined as SL priority.

[0063] In this invention, the first SL priority of the target resource can be the highest or lowest SL priority among at least some information corresponding to the target resource, such as the highest or lowest SL priority in the HARQ-ACK corresponding to the target resource; in this invention, the first SL priority value of the target resource can be the highest or lowest SL priority value among at least some information corresponding to the target resource, such as the highest or lowest SL priority value in the HARQ-ACK corresponding to the target resource.

[0064] In this embodiment of the application, when the target resource related to SL and the first resource at least partially overlap, or meet a conflict condition, or meet a reuse condition, it is determined whether to perform transmission. The reuse condition can be understood as at least some of the conditions required to reuse at least some of the information of the other resource on one of the target resource and the first resource for transmission.

[0065] In some implementations, 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.

[0066] For example, if the conditions for reuse are time-domain overlap and meeting priority requirements, then in the case of time-domain overlap between the first resource and the target resource, the final determination of whether reuse is possible is further based on whether the priority requirements are met by the first Uu priority, the second Uu priority, and / or the first SL priority.

[0067] In this embodiment of the application, the target resource and the first resource may or may not have Uu priority. Therefore, the target transmission is determined by using whether the target resource and the first resource have Uu priority, and / or the Uu priority of both, as a condition. That is, the target transmission is determined by at least one of the following:

[0068] Does the target resource have first Uu priority?

[0069] Does the first resource have a second Uu priority?

[0070] The target resource has the highest priority (Uu).

[0071] The second priority of the first resource (Uu).

[0072] In some implementations, the priority of Uu is at least one of the following:

[0073] The priority of physical layer signaling indication;

[0074] Priority of high-level configurations;

[0075] Business priorities;

[0076] Logical channel priority.

[0077] In some implementations, the target transmission is a target uplink transmission.

[0078] The aforementioned target resource and SL-related information refer to the fact that the target resource can be an SL resource or a Uu resource used to transmit SL information. Specifically, in one implementation, the target resource is a Uu resource used to transmit SL HARQ-ACK, such as a PUCCH used to transmit SL HARQ-ACK.

[0079] The target resource is a PUCCH for transmitting SL information, and the first resource is a PUSCH or PUCCH. When the target resource and the first resource have at least partial overlap, or meet the conflict condition or the multiplexing condition, the following four cases can be identified:

[0080] Case 1: One of them has a corresponding DCI; Table 1 shows the cases where there is at least partial overlap between various target resources and the first resource, or the conflict condition or the reuse condition is met:

[0081] Table 1

[0082]

[0083]

[0084] Case 2: One of them has a corresponding DCI; Table 2 shows the cases where there is at least partial overlap between various target resources and the first resource, or where the conflict condition or reuse condition is met:

[0085] Table 2

[0086]

[0087]

[0088] Case 3: All have corresponding DCIs; Table 3 shows the cases where there is at least partial overlap, conflict conditions, or reuse conditions between various target resources and the first resource:

[0089] Table 3

[0090]

[0091]

[0092] Case 4: No DCI; Table 4 shows the cases where there is at least partial overlap between various target resources and the primary resource, or where conflict conditions or reuse conditions are met:

[0093] Table 4

[0094]

[0095]

[0096]

[0097] In this invention, SL DCI is the DCI for scheduling, activating, or deactivating SL resources, such as DCI format 3-0 or DCI format 3-1, or SL-CS-RNTI or SL-RNTI scrambled DCI. SL PUCCH can be understood as a PUCCH used to transmit SL information, such as SL HARQ-ACK. UL DCI is the DCI for scheduling PUSCH, and DL DCI is the DCI for scheduling PDSCH.

[0098] For at least one of the three cases (case 1, case 2, and case 3) that have a corresponding DCI:

[0099] Base station guarantees and / or user expectations: The interval between the target resource and its corresponding DCI is not less than T. proc,2 +delta, and / or, the interval between the first resource and its corresponding DCI is not less than T. proc,2 +delta;

[0100] delta may be 0 or not 0, and may be positive or negative.

[0101] N2 represents the processing time, which may correspond to the user's capabilities.

[0102] T represents the processing time or preparation time, and T may contain N². For example, T can take the following values: T = (N² + d) 2,1 (2048+144)·κ2 -μ ·T C Or T = max((N2+d) 2,1 +d2)(2048+144)·κ2 -μ ·T C +T ext +T switch ,d 2,2 );

[0103] N2 corresponds to the first specific subcarrier spacing (SCS), and T corresponds to the second specific SCS;

[0104] Wherein: the first specific SCS is the minimum or maximum SCS among at least a subset of 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 corresponding to the target resource (e.g., the SL resource scheduled, activated, or deactivated by the aforementioned SL DCI); 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; or 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.

[0105] Alternatively, the first specific SCS is the SCS in the configured SCS that maximizes or minimizes N2;

[0106] Alternatively, the first specific SCS is the SCS that maximizes or minimizes N2;

[0107] Wherein: the second specific SCS is the minimum or maximum SCS among at least a subset of 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; or 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.

[0108] Alternatively, the second specific SCS is the SCS among the configured SCSs that maximizes or minimizes T;

[0109] Alternatively, the second specific SCS is the SCS that maximizes or minimizes T;

[0110] The control signaling corresponding to the first resource mentioned above is the control signaling for scheduling, indicating or activating the first resource (e.g., DCI or RRC);

[0111] The first control signaling corresponding to the target resource can be SL DCI or higher-level signaling that schedules, configures, or instructs the target resource.

[0112] The SL resource corresponding to the target resource can be the SL resource configured, scheduled, activated, or deactivated by the aforementioned SL DCI or higher-level signaling.

[0113] For example, if the target resource is a PUCCH used to transmit SL HARQ-ACK, then the first control signaling corresponding to the target resource is an SL DCI or higher-layer signaling that configures or indicates the target resource.

[0114] In the present invention, for cases where at least some information of the target resource is not ultimately transmitted, the base station can ensure that there is no overlap or conflict between the target resource and the first resource, or that the interval is not less than a preset value, and or that the user does not expect there to be overlap or conflict between the target resource and the first resource, or that the interval is less than a preset value.

[0115] The aforementioned first resource having a second Uu priority can be specifically interpreted as at least one of the following:

[0116] (1) Network side scheduling, configuring or indicating the second Uu priority of the first resource;

[0117] Specifically, in some implementations, the control signaling (e.g., DCI, MACCE, and / or RRC) that schedules, configures, or indicates the first resource carries priority indication information (e.g., priority indicator and / or phy-PriorityIndex);

[0118] (2) Predefine or preconfigure the second Uu priority of the first resource;

[0119] The predefined second Uu priority of the first resource can be protocol predefined. For example, if the control signaling (e.g., DCI, MAC CE, and / or RRC) that schedules, configures, or indicates the first resource does not carry priority indication information (e.g., priorityindicator and / or phy-PriorityIndex), the predefined second Uu priority of the first resource is low priority or priority low or priority index 0.

[0120] The fact that the first resource mentioned above does not have the second Uu priority can be interpreted as at least one of the following:

[0121] (1) The network side does not schedule, configure, or indicate the second Uu priority of the first resource;

[0122] Specifically, in some implementations, the control signaling (e.g., DCI, MACCE, and / or RRC) that schedules, configures, or indicates the first resource does not carry priority indication information (e.g., priority indicator and / or phy-PriorityIndex);

[0123] (2) The second Uu priority is not predefined or preconfigured for the first resource;

[0124] In some implementations, the first resource is used for at least one of the following:

[0125] (1) URLLC transmission;

[0126] (2) Transmissions above the priority threshold, i.e., high-priority transmissions;

[0127] (3) Transmission that exceeds reliability requirements, i.e., high-reliability transmission;

[0128] (4) Transmissions with latency below the latency threshold, packet delay budget (PDB) less than the PDB threshold, or remaining PDB less than the remaining PDB threshold, i.e., low latency, small PDB, or small remaining PDB.

[0129] At least one of (1)-(4) above can be considered to correspond to the first priority;

[0130] (5) eMBB transmission;

[0131] (6) Transmissions below the priority threshold, i.e., low-priority transmissions;

[0132] (7) Transmission below the reliability requirements, i.e., low-reliability transmission;

[0133] (8) Transmissions with latency exceeding the time threshold, PDB greater than the PDB threshold, or remaining PDB greater than the remaining PDB threshold, i.e., high latency, large PDB, or large remaining PDB.

[0134] At least one of (6)-(8) above can be considered to correspond to the second priority;

[0135] In some embodiments, the method further includes:

[0136] According to the mapping relationship, the first Uu priority of the target resource is determined based on the first SL priority; this mapping relationship can be understood as the correspondence between the first SL priority and the first Uu priority.

[0137] In this embodiment of the 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. According to the predefined mapping relationship, the first Uu priority of the target resource can be determined through the first SL priority of the target.

[0138] Furthermore, the first Uu priority of the target resource is a specific priority; or, when the first SL priority of the target resource meets a specific condition, the first Uu priority of the target resource is a specific priority.

[0139] In the embodiments of this application, when determining the first Uu priority based on the first SL priority, a uniform specific priority may be adopted for all types of first SL priorities, or the first Uu priority may be determined as a specific priority corresponding to a specific condition satisfied by the first SL priority.

[0140] The aforementioned specific priority may include one or more priorities, such as: high, medium, and low priorities, or priority 1, 2, 3, 4, and 5. This application embodiment does not specifically limit the types of priorities included in the specific priority.

[0141] Accordingly, the above-mentioned specific conditions also include one or more conditions. Optionally, different specific conditions may correspond to different specific priorities, or they may correspond to the same specific priority.

[0142] The following description uses a scenario with a specific priority level that includes two priority categories as an example:

[0143] Specifically, a particular priority includes at least one of the first priority and the second priority.

[0144] The aforementioned first priority can be interpreted as high priority, or priority high, or priority index 1, or URLLC. If the first Uu priority of the target resource and / or at least some of its corresponding information is the first priority, it can be understood that the target resource and / or at least some of its corresponding information has high priority, or priority high, or priority index 1, or URLLC. For example, the first priority may correspond to URLLC services. In this case, optionally, the target resource and / or its corresponding information are treated as URLLC, and the first Uu priority of the target resource is considered equivalent to the priority of the URLLC.

[0145] The aforementioned second priority can be interpreted as low priority, or priority index 0, or eMBB. If the first Uu priority of the target resource and / or at least some of its corresponding information is the second priority, it can be understood that the target resource and / or at least some of its corresponding information is of low priority, or priority index 0, or eMBB. For example, the second priority may correspond to eMBB services. In this case, optionally, the target resource and / or its corresponding information are considered eMBB, and the first Uu priority of the target resource is considered equivalent to the priority of eMBB.

[0146] Determining the first Uu priority of the target resource based on its first SL priority can include:

[0147] Case 1: Determine the first priority of the target resource as the first priority;

[0148] Case 2: Determine the first Uu priority of the target resource as the second priority;

[0149] Specifically, the specific conditions include at least one of the first condition and the second condition;

[0150] Determining the first Uu priority of the target resource based on its first SL priority may also include:

[0151] Case 3: When the first SL priority of the target resource meets the first condition, the first Uu priority of the target resource is the first priority; and or, when the first SL priority of the target resource meets the second condition, the first Uu priority of the target resource is the second priority.

[0152] Furthermore, the first condition includes one or more of the following:

[0153] The first priority level (SL) of the target resource is higher than or equal to the first preset priority.

[0154] The first priority value of the target resource is lower than or equal to the first preset priority value;

[0155] The condition that the second preset priority and / or second preset priority value is not configured or obtained needs to be clarified. Specifically, if the communication device of the executing entity is a network-side device (e.g., a base station), then this condition means the second preset priority and / or second preset priority value is not configured. In one optional embodiment, the second priority is the aforementioned first priority; in another optional embodiment, the second priority value is the aforementioned first priority value. If the communication device of the executing entity is a terminal, then this condition means the second preset priority and / or second preset priority value is not obtained; for example, the base station may not be configured, or the protocol may not be predefined.

[0156] The second condition is not met.

[0157] The second condition includes one or more of the following:

[0158] The first priority level (SL) of the target resource is higher than or equal to the third preset priority level;

[0159] The first priority value of the target resource is lower than or equal to the third preset priority value;

[0160] If a fourth preset priority and / or a fourth preset priority value is not configured or obtained, in one optional embodiment, the fourth priority is the first priority, the second priority and / or the third priority mentioned above; in another optional embodiment, the fourth priority value is the first priority value, the second priority value and / or the third priority value mentioned above.

[0161] The first priority level (SL) of the target resource is lower than or equal to the fifth preset priority level;

[0162] The first SL priority value of the target resource is higher than or equal to the fifth preset priority value. In one optional embodiment, the fifth priority is the first priority mentioned above. In another optional embodiment, the fifth priority value is the first priority value mentioned above.

[0163] The first condition is not met.

[0164] It should be noted that at least some of the first to fifth preset priorities mentioned above can correspond to the priorities corresponding to sl-PriorityThresholdULURLLC and / or sl-PriorityThreshold, and at least some of the first to fifth preset priority values ​​mentioned above can correspond to the priority values ​​corresponding to sl-PriorityThresholdULURLLC and / or sl-PriorityThreshold.

[0165] For example:

[0166] When the first SL priority of the target resource meets the first condition, the first Uu priority of the target resource is the first priority. One embodiment is that when the first SL priority value of the target resource is equal to or lower than sl-PriorityThreshold or sl-PriorityThresholdULURLLC, the target resource is the first priority.

[0167] When the first SL priority of the target resource meets the second condition, the first Uu priority of the target resource is the second priority. One embodiment is that when the first SL priority value of the target resource is equal to or higher than sl-PriorityThreshold or sl-PriorityThresholdULURLLC, the target resource is the second priority.

[0168] In this embodiment, the first SL priority of the target resource can be the lowest priority value in the SL HARQ-ACK corresponding to the target resource.

[0169] It should be noted that the first to fifth preset priorities (values) mentioned above may be the same or different, and this application embodiment does not specifically limit this.

[0170] Based on the same principle, if a specific priority includes three priorities: high, medium, and low, then determining the first Uu priority based on the first SL priority can include:

[0171] (1) The first Uu priority is high priority;

[0172] (2) The first Uu priority is medium priority;

[0173] (3) The first Uu priority is low priority;

[0174] (4) When the first SL priority satisfies the first condition, the first Uu priority is the higher priority;

[0175] (5) When the first SL priority satisfies the second condition, the first Uu priority is a medium priority;

[0176] (6) When the first SL priority satisfies the third condition (the specific content of the third condition can be set with reference to the first and second conditions), the first Uu priority is low priority;

[0177] For other priority types and quantities of specific priorities, the method of determining the first Uu priority based on the first SL priority can be set based on the same principle, and will not be elaborated further.

[0178] In some implementations, the first Uu priority of the target resource includes one or more of the following:

[0179] (1) The first specific Uu priority in the Uu priority of at least some information corresponding to the target resource;

[0180] The aforementioned first specific Uu priority can be the highest or lowest Uu priority among the Uu priorities of the information corresponding to the target resource;

[0181] Preferably, at least part of the information corresponding to the target resource is all the information corresponding to the target resource, such as all HARQ-ACK bits corresponding to the target resource;

[0182] For example: if the target resource corresponds to 3 HARQ-ACK bits, and the corresponding Uu priorities are high, low, and high respectively, then the Uu priority of the target resource is high or low.

[0183] (2) The Uu priority corresponding to a specific SL priority in the SL priority of at least some information corresponding to the target resource;

[0184] The specific SL priority mentioned above can be the Uu priority corresponding to the highest or lowest SL priority among the SL priorities of the information corresponding to the target resource;

[0185] Preferably, at least part of the information corresponding to the target resource is all the information corresponding to the target resource, such as all HARQ-ACK bits corresponding to the target resource;

[0186] For example: the target resource corresponds to 3 HARQ-ACK bits, and the corresponding SL priorities are priority values ​​1, 1, and 8 respectively. The SL priority value 1 corresponds to a high Uu priority, so the Uu priority of the target resource is high.

[0187] (3) The Uu priority of at least some information corresponding to the target resource.

[0188] Preferably, at least part of the information corresponding to the target resource is all the information corresponding to the target resource, such as all HARQ-ACK bits corresponding to the target resource;

[0189] For example: if the target resource corresponds to 3 HARQ-ACK bits, and the corresponding Uu priorities are high / low / high respectively, then the Uu priority of the target resource includes both high and low.

[0190] Similarly, the first Uu priority value of the target resource includes one or more of the following:

[0191] (1) The first specific Uu priority value in the Uu priority values ​​of at least some information corresponding to the target resource;

[0192] The aforementioned first specific Uu priority value can be the highest or lowest Uu priority value among the Uu priority values ​​of the information corresponding to the target resource;

[0193] Preferably, at least some of the information corresponding to the target resource is all the information corresponding to the target resource;

[0194] For example: if the target resource corresponds to 3 HARQ-ACK bits, and the corresponding Uu priority values ​​are 1, 1, 0, then the Uu priority value of the target resource is 1 or 0.

[0195] (2) The Uu priority value corresponding to a specific SL priority value in at least some of the information corresponding to the target resource;

[0196] The specific SL priority value mentioned above can be the 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;

[0197] Preferably, at least some of the information corresponding to the target resource is all the information corresponding to the target resource;

[0198] For example: if the target resource corresponds to 3 HARQ-ACK bits, with corresponding SL priority values ​​of 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.

[0199] (3) The Uu priority value of at least some information corresponding to the target resource.

[0200] Preferably, at least some of the information corresponding to the target resource is all the information corresponding to the target resource;

[0201] For example: if the target resource corresponds to 3 HARQ-ACK bits, and the corresponding Uu priority values ​​are 1, 1, and 0 respectively, then the Uu priority value of the target resource includes 1 and 0.

[0202] It should be noted that in the embodiments of this application, the correspondence between priority values ​​and priorities can be either ascending or descending order. Ascending order means that the larger the priority value, the higher the priority; descending order means that the larger the priority value, the lower the priority. The above examples are described in the descending order, but it is understood that the same applies to the ascending order. When corresponding to the ascending order, if a priority value in the description of this invention is higher than another priority value, it is correspondingly replaced with a priority value lower than another priority value, and / or, if it is written that a priority value is lower than another priority value, it is correspondingly replaced with another priority value.

[0203] In some implementations, the target resource includes one or more of the following:

[0204] (1) The resource where the target object is located, such as an SL resource or a Uu resource, the target object includes SL channels, SL signals, SL signaling, SL information and / or SL messages;

[0205] For example: SL information is SL HARQ-ACK.

[0206] (2) Uu channels, signals and / or resources used to transmit or indicate target content, the target content including SL signals, SL signaling, SL information and / or SL messages;

[0207] The aforementioned transmissions include: forwarding, carrying, transmitting, and reporting;

[0208] For example: PUCCH and / or PUSCH carrying SL HARQ-ACK; or PUCCH carrying SL SR; or PUCCH and / or PUSCH carrying SL Channel-State Information (CSI);

[0209] (3)SL HARQ-ACK;

[0210] (4) Uplink resources (PUCCH and / or PUSCH) carrying SL HARQ-ACK.

[0211] In some implementations, the information corresponding to the target resource can be at least one of the following:

[0212] (1) Information that the target resources intend, expect, or may forward, carry, and / or report;

[0213] (2) Information related to the target resources.

[0214] In some implementations, the target resource does not have a first Uu priority, which can be interpreted as at least one of the following:

[0215] (1) The network side does not schedule, configure or indicate the first Uu priority of the target resource;

[0216] Specifically, in some implementations, the control signaling (e.g., DCI, MACCE, and / or RRC) that schedules, configures, or indicates the first resource does not carry priority indication information (e.g., priority indicator and / or phy-PriorityIndex);

[0217] (2) The first Uu priority is not predefined or preconfigured for the target resource.

[0218] The following describes the methods for determining the target transmission under various conditions. In some embodiments, after determining the target transmission, the target transmission is performed on the first resource. The following description will take the target transmission performed on the first resource as an example:

[0219] 1. The target resource has a first Uu priority, and the first resource has a second Uu priority. Determining the target transmission includes at least one of the following:

[0220] (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 is less than the first preset difference, at least part of the information corresponding to the target resource is transmitted on the first resource, that is, multiplexing transmission is only possible when the Uu priorities are the same.

[0221] Specifically, when the first Uu priority of the target resource and the second Uu priority of the first resource are the same and are of the first priority, at least some information corresponding to the target resource is transmitted on the first resource;

[0222] Optionally, this situation can be combined with Case 1 in the aforementioned determination of the first Uu priority based on the first SL priority. Alternatively, it can be combined with Case 2 and Case 3 in the determination of the first Uu priority based on the first SL priority.

[0223] Specifically, when the first Uu priority of the target resource and the second Uu priority of the first resource are the same and the second priority is the second priority, at least some information corresponding to the target resource is transmitted on the first resource.

[0224] Optionally, this situation can be combined with Case 2 in the aforementioned determination of the first Uu priority based on the first SL priority. Alternatively, Case 1 and Case 3 in the determination of the first Uu priority based on the first SL priority can also be combined.

[0225] (2) When the first Uu priority of the target resource and the second Uu priority of the first resource are different or the difference is greater than the second preset difference, at least part of the information corresponding to the target resource is not transmitted on the first resource, that is, transmission cannot be reused when the Uu priorities are different.

[0226] 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 some information corresponding to the target resource is not transmitted on the first resource;

[0227] This situation can be combined with Case 1 in the aforementioned determination of the first Uu priority based on the first SL priority. It can also be combined with Case 2 and Case 3 in the determination of the first Uu priority based on the first SL priority.

[0228] 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 some information corresponding to the target resource is not transmitted on the first resource.

[0229] This situation can be combined with Case 2 in the aforementioned determination of the first Uu priority based on the first SL priority. It can also be combined with Case 1 and Case 3 in the determination of the first Uu priority based on the first SL priority.

[0230] Furthermore, when the first Uu priority of the target resource and the second Uu priority of the first resource are different, the target resource or the first resource is transmitted according to the Uu priority.

[0231] Specifically, when the first Uu priority of the target resource and the second Uu priority of the first resource are different, the one with the higher Uu priority is transmitted. For example, when the Uu priority corresponding to the target resource is high, or priority high, or priority index 1, and the Uu priority corresponding to the first resource is low, or priority low, or priority index 0, the target resource is transmitted.

[0232] When the priority of the target resource is low (or priority low or priority index 0), and the priority of the first resource is high (or priority high or priority index 1), the first resource is transmitted.

[0233] It should be noted that while transmitting the Uu with higher priority, the Uu with lower priority is discarded.

[0234] 2. The target resource has a first Uu priority, and the first resource may or may not have a second Uu priority; that is, it does not matter whether the first resource has a second Uu priority at this time. Determining the target transmission includes at least one of the following:

[0235] (1) When the first Uu priority of the target resource is higher than or equal to the first specific priority and / or lower than or equal to the second specific priority, at least part of the information corresponding to the target resource is transmitted on the first resource;

[0236] (2) When the first Uu priority of the target resource is higher than or equal to the third specific priority, and / or lower than or equal to the fourth specific priority, at least part of the information corresponding to the target resource shall not be transmitted on the first resource;

[0237] That is, transmissions cannot be reused when the Uu priorities of the target resources are different and the requirements are met.

[0238] Optionally, at least some of the aforementioned first specific priority, second specific priority, third specific priority, and fourth specific priority may be priorities corresponding to sl-PriorityThresholdULURLLC and / or sl-PriorityThreshold, such as the Uu priority corresponding to sl-PriorityThresholdULURLLC and / or sl-PriorityThreshold.

[0239] In this invention, the priorities corresponding to sl-PriorityThresholdULURLLC and / or sl-PriorityThreshold are the Uu priority or SL priority corresponding to sl-PriorityThresholdULURLLC and / or sl-PriorityThreshold. In one embodiment, sl-PriorityThresholdULURLLC and / or sl-PriorityThreshold are priority values, and the SL priority corresponding to sl-PriorityThresholdULURLLC and / or sl-PriorityThreshold is the SL priority corresponding to that value. In one embodiment, the Uu priority corresponding to sl-PriorityThresholdULURLLC and / or sl-PriorityThreshold can be interpreted as the Uu priority corresponding to the SL priority corresponding to sl-PriorityThresholdULURLLC and / or sl-PriorityThreshold.

[0240] 3. The target resource may or may not have a first Uu priority, and the first resource has a second Uu priority. That is, at this time, it does not matter whether the target resource has a first Uu priority or whether the Uu priority of the target resource is defined. It can be determined by the combination of case 1 / 2 / 3 in the above-mentioned determination of the first Uu priority based on the first SL priority, or it can work when the Uu priority of the target resource is not defined, determining the target transmission, including at least one of the following:

[0241] (1) When the second Uu priority of the first resource is the first priority, at least part of the information corresponding to the target resource is not transmitted on the first resource;

[0242] (2) When the second Uu priority of the first resource is the second priority, at least part of the information corresponding to the target resource is transmitted on the first resource;

[0243] The first priority is higher than the second priority.

[0244] That is, transmission can be reused only when the first Uu resource and / or its corresponding information is of low priority or priority low or priorityindex 0 or embb.

[0245] 4. The target resource may or may not have a first Uu priority, and the first resource has a second Uu priority. That is, at this time, it does not matter whether the target resource has a first Uu priority or whether the Uu priority of the target resource is defined. It can be determined by the combination of case 1 / 2 / 3 in the above-mentioned determination of the first Uu priority based on the first SL priority, or it can work when the Uu priority of the target resource is not defined, determining the target transmission, including at least one of the following:

[0246] (1) When the second Uu priority of the first resource is the first priority, at least part of the information corresponding to the target resource is transmitted on the first resource;

[0247] (2) When the second Uu priority of the first resource is the second priority, at least part of the information corresponding to the target resource is not transmitted on the first resource;

[0248] The first priority is higher than the second priority.

[0249] That is, transmission can be reused only when the first Uu resource and / or its corresponding information is of high priority or priority high or priorityindex 1 or URLLC.

[0250] 5. Determine the target transmission, including at least one of the following:

[0251] (1) Transmit at least some information corresponding to the target resource on the first resource;

[0252] (2) When the first SL priority of the target resource is higher than or equal to the fifth specific priority, and / or lower than or equal to the sixth specific priority, at least part of the information corresponding to the target resource is transmitted on the first resource;

[0253] (3) When the first SL priority of the target resource is higher than or equal to the seventh specific priority and / or lower than or equal to the eighth specific priority, at least part of the information corresponding to the target resource is transmitted on the first resource.

[0254] Optionally, at least some of the aforementioned fifth to eighth specific priorities may be sl-PriorityThresholdULURLLC and / or the SL priority corresponding to sl-PriorityThreshold.

[0255] For example: if the first SL priority of the target resource is equal to or higher than sl-PriorityThresholdURLLC or the SL priority corresponding to sl-PriorityThreshold, then at least part of the information corresponding to the target resource can be transmitted;

[0256] Furthermore, when the first resource is the first priority, if the first SL priority of the target resource is equal to or higher than the SL priority corresponding to sl-PriorityThresholdULURLLC or sl-PriorityThreshold, then at least part of the information corresponding to the target resource can be transmitted.

[0257] For example, if the first SL priority of the target resource is equal to or lower than the SL priority corresponding to sl-PriorityThreshold or sl-PriorityThresholdURLLC, then at least some information corresponding to the target resource can be transmitted.

[0258] Furthermore, when the first resource is the second priority, if the first SL priority of the target resource is equal to or lower than the SL priority corresponding to sl-PriorityThreshold or sl-PriorityThresholdURLLC, then at least some information corresponding to the target resource can be transmitted.

[0259] Example 1. The target resource is a PUCCH used for transmitting SL HARQ-ACK, and the first resource is a PUSCH; it includes at least one of the following:

[0260] i. SL HARQ-ACK will only be multiplexed to PUSCH if its SL priority value is greater than or equal to the priority value corresponding to sl-PriorityThreshold or sl-PriorityThresholdULURLLC. Alternatively, SL HARQ-ACK will only be multiplexed to PUSCH if its SL priority is equal to or lower than the priority corresponding to sl-PriorityThreshold or sl-PriorityThresholdULURLLC.

[0261] ii. SL HARQ-ACK will only be reused in PUSCH if its SL priority value is less than or equal to sl-PriorityThresholdULURLLC or the priority value corresponding to sl-PriorityThreshold. Alternatively, SL HARQ-ACK will only be reused in PUSCH if its SL priority is equal to or higher than the priority value corresponding to sl-PriorityThresholdULURLLC or sl-PriorityThreshold.

[0262] Example 2.

[0263] i. If the first resource is of low priority (either priority low, priority index 0, or embb), SL HARQ-ACK will only be multiplexed to PUSCH if its SL priority value is greater than or equal to sl-PriorityThreshold. Alternatively, SL HARQ-ACK will only be multiplexed to PUSCH if its SL priority is equal to or lower than the priority corresponding to sl-PriorityThreshold.

[0264] ii. If the first resource is of low priority (either priority low, priority index 0, or embb), SL HARQ-ACK will only be multiplexed to PUSCH if the SL priority value of SL HARQ-ACK is greater than or equal to sl-PriorityThresholdULURLLC. Alternatively, SL HARQ-ACK will only be multiplexed to PUSCH if the SL priority of SL HARQ-ACK is equal to or lower than the priority corresponding to sl-PriorityThresholdULURLLC.

[0265] iii. When the first resource has a high priority (or priority high, priorityindex 1, or URLLC), SL HARQ-ACK will only be reused in PUSCH if its SL priority value is less than or equal to sl-PriorityThresholdULURLLC. Alternatively, SL HARQ-ACK will only be reused in PUSCH if its SL priority is equal to or higher than the priority corresponding to sl-PriorityThresholdULURLLC.

[0266] v. When the first resource has a high priority (or priority high, priority index 1, or URLLC), SLHARQ-ACK will only be reused in PUSCH if its SL priority value is less than or equal to sl-PriorityThreshold. Alternatively, SLHARQ-ACK will only be reused in PUSCH if its SL priority is equal to or higher than the priority corresponding to sl-PriorityThreshold.

[0267] It should be noted that the "at least part of the information" mentioned here and the "at least part of the information" mentioned earlier in determining the target transmission based on relevant priorities may refer to different objects or the same objects.

[0268] 6. When the first resource has a second Uu priority, and / or the first control signaling carries priority indication information (e.g., priority indicator and / or phy-PriorityIndex), at least some information corresponding to the target resource is transmitted on the first resource; wherein the first control signaling is used to schedule, configure or indicate the first resource, such as DCI, MAC CE and / or RRC.

[0269] 7. When 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), at least some information corresponding to the target resource is transmitted on the first resource; wherein, the first control signaling is used to schedule, configure or indicate the first resource, such as DCI, MAC CE and / or RRC.

[0270] Furthermore, when transmitting at least a portion of the information corresponding to the target resource on the first resource, the at least a portion of the information includes at least one of the following:

[0271] (a) All information corresponding to the target resource, that is, all information corresponding to the target resource can be transmitted on the first resource;

[0272] (b) Information that has the same Uu priority as the first resource;

[0273] That is, information with the same priority as the Uu corresponding to the first resource can be transmitted on the first resource from the information corresponding to the target resource:

[0274] For example, if the first resource is of high priority, priority high, priority index 1, or URLLC, then the information corresponding to the high priority, priority high, priority index 1, or URLLC in the target resource information can be transmitted.

[0275] For example, if the first resource is of low priority, priority low, priority index 0, or embb, then the information corresponding to the low priority, priority low, priority index 0, or embb in the target resource information can be transmitted.

[0276] (c) Information with a second Uu priority not lower than that of the first resource;

[0277] For example, if the first resource is of high priority, priority high, priority index 1, or URLLC, then the information corresponding to the high priority, priority high, priority index 1, or URLLC in the target resource information can be transmitted.

[0278] For example, if the first resource is of low priority or priority index 0 or embb, then the information corresponding to the target resource, which is of low priority or priority index 0 or embb, and the information corresponding to high priority or priority index 1 or URLLC, can be transmitted.

[0279] (d) Information with a priority no higher than that of the first resource's second Uu priority;

[0280] For example, if the first resource is of high priority or priority high or priority index 1 or URLLC, then the information corresponding to the target resource, which corresponds to low priority or priority low or priority index 0 or embb, and the information corresponding to high priority or priority high or priority index 1 or URLLC, can be transmitted.

[0281] For example, if the first resource is of low priority, priority low, priority index 0, or embb, then the information corresponding to the low priority, priority low, priority index 0, or embb in the target resource information can be transmitted.

[0282] (e) corresponds to a first SL priority that is higher than the sixth preset priority;

[0283] (f) Information that the first SL priority value is lower than the sixth preset priority value;

[0284] (g) corresponds to a first Uu priority that is higher than the seventh preset priority;

[0285] (h) indicates that the first Uu priority value is lower than the seventh preset priority value;

[0286] (i) The corresponding first SL priority is lower than the eighth preset priority;

[0287] (j) Information whose first SL priority value is higher than the eighth preset priority value;

[0288] (k) corresponds to a first Uu priority that is lower than the ninth preset priority;

[0289] (l) The information that the first Uu priority value is higher than the ninth preset priority value.

[0290] The aforementioned sixth to ninth preset priorities (values) may be the same or different. Optionally, at least a portion of the aforementioned sixth to ninth preset priorities may correspond to the priority corresponding to sl-PriorityThresholdULURLLC, and / or the priority corresponding to sl-PriorityThreshold. For example, at least a portion of the aforementioned sixth to ninth preset priorities may correspond to the SL priority corresponding to sl-PriorityThresholdULURLLC, the SL priority corresponding to sl-PriorityThreshold, the Uu priority corresponding to sl-PriorityThresholdULURLLC, and / or the Uu priority corresponding to sl-PriorityThreshold.

[0291] Furthermore, when at least some information corresponding to the target resource is not transmitted on the first resource, the at least some information includes at least one of the following:

[0292] (a) All information corresponding to the target resource, i.e., all information corresponding to the target resource cannot be transmitted on the first resource;

[0293] (b) Information with a different Uu priority from the first resource, i.e., information with a different Uu priority from the information corresponding to the target resource and the Uu priority corresponding to the first Uu resource cannot be transmitted on the first resource;

[0294] For example, if the first resource has high priority, priority index 1, or URLLC, then information corresponding to low priority, priority index 0, or eMBB in the target resource's information cannot be transmitted.

[0295] For example, if the first resource has a low priority, priority low, priority index 0, or embb, then the information corresponding to the target resource with a high priority, priority high, priority index 1, or URLLC cannot be transmitted.

[0296] (c) Information with a second Uu priority not lower than that of the first resource;

[0297] For example, if the first Uu resource is of high priority or priority high or priority index 1 or URLLC, then the information corresponding to the high priority or priority high or priority index 1 or URLLC in the target resource cannot be transmitted.

[0298] For example, if the first Uu resource is of low priority or priority low or priority index 0 or embb, then the information corresponding to the low priority or priority low or priority index 0 or embb and the information corresponding to the high priority or priority high or priority index 1 or URLLC in the target resource cannot be transmitted.

[0299] (d) Information with a priority no higher than that of the first resource's second Uu priority;

[0300] For example, if the first Uu resource is of high priority or priority high or priority index 1 or URLLC, then the information corresponding to the target resource that corresponds to low priority or priority low or priority index 0 or embb, and the information corresponding to high priority or priority high or priority index 1 or URLLC, cannot be transmitted.

[0301] For example, if the first Uu resource is of low priority or priority low or priority index 0 or embb, then the information corresponding to the low priority or priority low or priority index 0 or embb in the target resource's information cannot be transmitted.

[0302] (e) The first SL priority is lower than the tenth preset priority;

[0303] (f) Information that the first SL priority value is higher than the tenth preset priority value;

[0304] (g) corresponds to a first Uu priority that is lower than the eleventh preset priority;

[0305] (h) indicates that the first Uu priority value is higher than the eleventh preset priority value;

[0306] (i) The first SL priority is higher than the twelfth preset priority;

[0307] (j) Information that the first SL priority value is lower than the twelve preset priority values;

[0308] (k) corresponds to a first Uu priority that is higher than the thirteenth preset priority;

[0309] (l) The information that the first Uu priority value is lower than the thirteenth preset priority value.

[0310] The aforementioned tenth to thirteenth preset priorities (values) may be the same or different. Optionally, at least a portion of the aforementioned tenth to thirteenth preset priorities may correspond to the priority corresponding to sl-PriorityThresholdULURLLC, and / or the priority corresponding to sl-PriorityThreshold. Optionally, at least a portion of the aforementioned tenth to thirteenth preset priorities may correspond to the SL priority corresponding to sl-PriorityThresholdULURLLC, the SL priority corresponding to sl-PriorityThreshold, the Uu priority corresponding to sl-PriorityThresholdULURLLC, and / or the Uu priority corresponding to sl-PriorityThreshold.

[0311] If the transmitted information is part of all the information corresponding to the target resource, or not part of all the information corresponding to the target resource, it can be understood that at least part of the information is discarded.

[0312] In some implementations, the target resource includes multiple Uu priorities, and / or the information corresponding to the target resource corresponds to different Uu priorities. Furthermore, when multiple first resources overlap with the target resource, meet conflict conditions, or meet reuse conditions, this method further includes:

[0313] The target transmission is determined based on the second Uu priority of each first resource.

[0314] Specifically, the target transmission is determined by considering each first resource according to the methods described above.

[0315] For example, information corresponding to a certain Uu priority can be reused on the first Uu resource with the same Uu priority;

[0316] For example: if the target resource PUCCH corresponds to two sidelink HARQ-ACK bits with high and low Uu priorities respectively, and the target resource and two PUSCHs with high and low Uu priorities overlap, then the sidelink HARQ-ACK bit with the high Uu priority will be multiplexed on the PUSCH with the high Uu priority, and the sidelink HARQ-ACK bit with the low Uu priority will be multiplexed on the PUSCH with the low Uu priority.

[0317] In some implementations, when multiple first resources overlap with the target resource, or meet conflict conditions, or meet reuse conditions, the method further includes:

[0318] (1) Determine the target transmission according to the second Uu priority of each first resource in a preset order; wherein, the preset order includes: the time domain order of multiple first resources, the frequency domain order of multiple first resources, the identification order of multiple first resources, and / or the second Uu priority order of multiple first resources; for example, the order of time domain resources, specifically the order of time domain start points, the order of time domain end points; the order of frequency domain position, etc.

[0319] (2) Determine the target transmission based on the second specific Uu priority in the second Uu priority.

[0320] For example: Consider the first resource with the highest priority, lowest priority, higher than threshold 1, or lower than threshold 2 among multiple first resources to determine the target transmission.

[0321] In some implementations, the priority of the target transmission is any one of the following:

[0322] The second Uu priority of the first resource;

[0323] The target resource has the highest priority (Uu).

[0324] The first SL priority of the target resource.

[0325] Furthermore, when 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;

[0326] Alternatively, 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.

[0327] Similarly, in some implementations, the priority value of the target transmission is any one of the following:

[0328] The second Uu priority value of the first resource;

[0329] The first Uu priority value of the target resource;

[0330] The first priority value of the target resource.

[0331] 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;

[0332] Alternatively, 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.

[0333] In some implementations, the first resource is a PUCCH and / or PUSCH resource, such as a PUCCH and / or PUSCH with Uu priority. For example, it can be a PUCCH and / or PUSCH corresponding to information with corresponding Uu priority, or it can be other uplink signals, such as uplink reference signals. Specifically, there are SRS and Positioning RS.

[0334] See Figure 3 This application provides a priority definition method applied to a communication device, which may be a terminal or a network-side device. The method includes:

[0335] Step 301: Configure or obtain the mapping relationship between the first Uu priority and the first SL priority of the target resource;

[0336] It should be noted that if the communication device of the executing entity is a network-side device (such as a base station), then this step is to configure the mapping relationship between the first Uu priority and the first SL priority of the target resource; if the communication device of the executing entity is a terminal, then this step is to obtain the mapping relationship between the first Uu priority and the first SL priority of the target resource; for example, it can be base station configuration, protocol predefined, preconfigured, user-defined, etc.

[0337] Step 302: Determine the first Uu priority of the target resource based on the mapping relationship;

[0338] The above mapping relationship can be understood as the correspondence between the first SL priority and the first Uu priority.

[0339] It should be noted that the above mapping relationship can include cases where different first SL priorities correspond to different first Uu priorities, or cases where the first Uu priority is defined as the same priority regardless of the first SL priority of the target resource, such as defining them as the first priority or the second priority.

[0340] In this embodiment of the application, the target resource is related to SL. Being related to SL means that the target resource can be an SL resource or a Uu resource used to transmit SL-related information.

[0341] 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 first SL priority of the target resource includes: the SL priority of the target resource, and / or the SL priority of at least some information corresponding to the target resource.

[0342] In some implementations, the mapping relationship satisfies:

[0343] The first Uu priority of the target resource is a specific priority;

[0344] or,

[0345] When the first SL priority of the target resource meets a specific condition, the first Uu priority of the target resource is the specific priority corresponding to the specific condition.

[0346] In this embodiment of the 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. According to the predefined mapping relationship, the first Uu priority of the target resource can be determined through the first SL priority of the target.

[0347] Furthermore, the first Uu priority of the target resource is a specific priority; or, when the first SL priority of the target resource meets a specific condition, the first Uu priority of the target resource is a specific priority.

[0348] In the embodiments of this application, when determining the first Uu priority based on the first SL priority, a uniform specific priority may be adopted for all types of first SL priorities, or the first Uu priority may be determined as a specific priority corresponding to a specific condition satisfied by the first SL priority.

[0349] The aforementioned specific priority may include one or more priorities, such as: high, medium, and low priorities, or priority 1, 2, 3, 4, and 5. This application embodiment does not specifically limit the types of priorities included in the specific priority.

[0350] Accordingly, the aforementioned specific conditions also include one or more conditions, that is, different specific conditions correspond to different specific priorities.

[0351] The following description uses a scenario with a specific priority level that includes two priority categories as an example:

[0352] Specifically, a particular priority includes at least one of the first priority and the second priority.

[0353] The aforementioned "first priority" can be interpreted as high priority, or priority high, or priority index 1, or URLLC. If the first Uu priority of the target resource and / or at least some of its corresponding information is the first priority, it can be understood that the target resource and / or its corresponding at least some information has high priority, or priority high, or priority index 1, or URLLC. For example, the first priority may correspond to URLLC services. In this case, optionally, the target resource and / or its corresponding information can be considered as URLLC, and the first Uu priority of the target resource is considered equivalent to the priority of the URLLC.

[0354] The aforementioned second priority can be interpreted as low priority, or priority index 0, or eMBB. If the first Uu priority of the target resource and / or at least some of its corresponding information is the second priority, it can be understood that the target resource and / or at least some of its corresponding information is of low priority, or priority index 0, or eMBB. For example, the second priority may correspond to eMBB services. In this case, optionally, the target resource and / or its corresponding information can be considered as eMBB, and the first Uu priority of the target resource is considered equivalent to the priority of eMBB.

[0355] Determining the first Uu priority of the target resource based on its first SL priority can include:

[0356] Case 1: Determine the first priority of the target resource as the first priority;

[0357] Case 2: Determine the first Uu priority of the target resource as the second priority;

[0358] Specifically, the specific conditions include at least one of the first condition and the second condition;

[0359] Determining the first Uu priority of the target resource based on its first SL priority may also include:

[0360] Case 3: When the first SL priority of the target resource meets the first condition, the first Uu priority of the target resource is the first priority; and or, when the first SL priority of the target resource meets the second condition, the first Uu priority of the target resource is the second priority.

[0361] Furthermore, the first condition includes one or more of the following:

[0362] The first priority level (SL) of the target resource is higher than or equal to the first preset priority.

[0363] The first priority value of the target resource is lower than or equal to the first preset priority value;

[0364] The second preset priority and / or the second preset priority value has not been configured or obtained.

[0365] The second condition is not met.

[0366] The second condition includes one or more of the following:

[0367] The first priority level (SL) of the target resource is higher than or equal to the third preset priority level;

[0368] The first priority value of the target resource is lower than or equal to the third preset priority value;

[0369] The fourth preset priority and / or the fourth preset priority value have not been configured or obtained.

[0370] The first priority level (SL) of the target resource is lower than or equal to the fifth preset priority level;

[0371] The first SL priority value of the target resource is higher than or equal to the fifth preset priority value. In an optional embodiment, the fifth priority is the first priority mentioned above.

[0372] The first condition is not met.

[0373] It should be noted that at least some of the first to fifth preset priorities mentioned above can correspond to the priorities corresponding to sl-PriorityThresholdULURLLC and / or sl-PriorityThreshold, and at least some of the first to fifth preset priority values ​​mentioned above can correspond to the priority values ​​corresponding to sl-PriorityThresholdULURLLC and / or sl-PriorityThreshold.

[0374] It should be noted that the first to fifth preset priorities (values) mentioned above may be the same or different, and this application embodiment does not specifically limit this.

[0375] Based on the same principle, if a specific priority includes three priorities: high, medium, and low, then determining the first Uu priority based on the first SL priority can include:

[0376] (1) The first Uu priority is high priority;

[0377] (2) The first Uu priority is medium priority;

[0378] (3) The first Uu priority is low priority;

[0379] (4) When the first SL priority satisfies the first condition, the first Uu priority is the higher priority;

[0380] (5) When the first SL priority satisfies the second condition, the first Uu priority is a medium priority;

[0381] (6) When the first SL priority satisfies the third condition (the specific content of the third condition can be set with reference to the first and second conditions), the first Uu priority is low priority;

[0382] For other priority types and quantities of specific priorities, the method of determining the first Uu priority based on the first SL priority can be set based on the same principle, and will not be elaborated further.

[0383] In some implementations, the first Uu priority of the target resource includes one or more of the following:

[0384] (1) The first specific Uu priority in the Uu priority of at least some information corresponding to the target resource;

[0385] The aforementioned first specific Uu priority can be the highest or lowest Uu priority among the Uu priorities of the information corresponding to the target resource;

[0386] Preferably, at least some of the information corresponding to the target resource is all the information corresponding to the target resource;

[0387] For example: if the target resource corresponds to 3 HARQ-ACK bits, and the corresponding Uu priorities are high, low, and high respectively, then the Uu priority of the target resource is high or low.

[0388] (2) The Uu priority corresponding to a specific SL priority in the SL priority of at least some information corresponding to the target resource;

[0389] The specific SL priority mentioned above can be the Uu priority corresponding to the highest or lowest SL priority among the SL priorities of the information corresponding to the target resource;

[0390] Preferably, at least some of the information corresponding to the target resource is all the information corresponding to the target resource;

[0391] For example: the target resource corresponds to 3 HARQ-ACK bits, and the corresponding SL priorities are priority values ​​1, 1, and 8 respectively. The SL priority value 1 corresponds to a high Uu priority, so the Uu priority of the target resource is high.

[0392] (3) The Uu priority of at least some information corresponding to the target resource.

[0393] For example: if the target resource corresponds to 3 HARQ-ACK bits, and the corresponding Uu priorities are high / low / high respectively, then the Uu priority of the target resource includes both high and low.

[0394] Similarly, the first Uu priority value of the target resource includes one or more of the following:

[0395] (1) The first specific Uu priority value in the Uu priority values ​​of at least some information corresponding to the target resource;

[0396] The aforementioned first specific Uu priority value can be the highest or lowest Uu priority value among the Uu priority values ​​of the information corresponding to the target resource;

[0397] Preferably, at least some of the information corresponding to the target resource is all the information corresponding to the target resource;

[0398] For example: if the target resource corresponds to 3 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.

[0399] (2) The Uu priority value corresponding to a specific SL priority value in at least some of the information corresponding to the target resource;

[0400] The specific SL priority value mentioned above can be the 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;

[0401] Preferably, at least some of the information corresponding to the target resource is all the information corresponding to the target resource;

[0402] For example: if the target resource corresponds to 3 HARQ-ACK bits, with corresponding SL priority values ​​of 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.

[0403] (3) The Uu priority value of at least some information corresponding to the target resource.

[0404] Preferably, at least some of the information corresponding to the target resource is all the information corresponding to the target resource;

[0405] For example: if the target resource corresponds to 3 HARQ-ACK bits, and the corresponding Uu priority values ​​are 1, 1, and 0 respectively, then the Uu priority value of the target resource includes 1 and 0.

[0406] It should be noted that in the embodiments of this application, the correspondence between priority value and priority can be either ascending or descending order. Ascending order means that the larger the priority value, the higher the priority; descending order means that the larger the priority value, the lower the priority. The above example is described in the case of descending order, but it can be understood that the same applies to the case of ascending order.

[0407] In some implementations, the target resource includes one or more of the following:

[0408] (1) The resource where the target object is located, such as an SL resource, which includes SL channels, SL signals, SL signaling, SL information and / or SL messages;

[0409] For example: SL information is SL HARQ-ACK.

[0410] (2) Uu channels, signals and / or resources used to transmit or indicate target content, the target content including SL signals, SL signaling, SL information and / or SL messages;

[0411] The aforementioned transmissions include: forwarding, carrying, transmitting, and reporting;

[0412] For example: a PUCCH and / or PUSCH carrying SL HARQ-ACK; or a PUCCH carrying SL SR; or a PUCCH and / or PUSCH carrying SLCSI;

[0413] (3)SL HARQ-ACK;

[0414] (4) Uplink resources (PUCCH and / or PUSCH) carrying SL HARQ-ACK.

[0415] In some implementations, the information corresponding to the target resource can be at least one of the following:

[0416] (1) Information that the target resources intend, expect, or may forward, carry, and / or report;

[0417] (2) Information related to the target resources.

[0419] In the following embodiment, SL PUCCH is a PUCCH that carries SL-related information (e.g., SL HARQ-ACK).

[0420] Example 1: Different priorities cannot be reused;

[0421] Optionally, if a Uu PUSCH with a low priority, or a priority index of 0 or an embb, overlaps with an SL PUCCH with a high priority, or a priority index of 1 or a URLLC, or if the SL PUCCH meets the conflict condition or the reuse condition, the SL HARQ-ACK on the SL PUCCH cannot be reused on the PUSCH.

[0422] Optionally, if a Uu PUSCH with a high priority, priority high, priority index 1 or URLLC overlaps with an SL PUCCH with a low priority, priority low, priority index 0 or embb, or meets the conflict condition or the reuse condition, the SL HARQ-ACK on the SL PUCCH cannot be reused on the PUSCH.

[0423] Example 2: Items with the same priority can be reused;

[0425] Optionally, when a Uu PUSCH with a low priority, or a priority index of 0 or an embb overlaps with a SLPUCCH with a low priority, or a priority index of 0 or an embb, or meets the conflict condition or the reuse condition, the SL HARQ-ACK on the SL PUCCH can be reused on the PUSCH.

[0426] Example 3: Can only be reused on PUSCHs that have not been indicated with priority or low priority, or with priority low, priority index 0, or embb;

[0427] Optionally, when a Uu PUSCH with no indicated priority or low priority, or with priority low or priority index 0 or embb overlaps with an SL PUCCH, or meets the conflict condition or the reuse condition, the SL HARQ-ACK on the SL PUCCH can be reused on a PUSCH with priority embb.

[0428] Optionally, if a Uu PUSCH with a priority of indicated priority or high priority, or priority high, or priority index 1 or URLLC overlaps with an SL PUCCH or meets a conflict condition or a reuse condition, the SL HARQ-ACK on the SL PUCCH cannot be reused on a PUSCH with a priority of indicated priority or high priority, or priority high, or priority index 1 or URLLC.

[0429] Example 4: SL HARQ-ACK can only be multiplexed on low-priority PUSCHs, or PUSCHs with priority low, priorityindex 0, or embb, or PUSCHs without priority (e.g., PUSCHs scheduled by DCI format that do not have a priority indicator field).
