可选地，在SL资源分配模式2中，当UE需要为其将要传输的一个或多个传输块选择(或重选)用于初传和/或重传的资源时，可以先通过第一资源子集确定过程(或者称为“第一资源集合确定过程”)确定一个资源子集(例如记为资源子集S A，或者称为资源集合S A)，然后基于所述资源子集S A执行资源选择或资源重选。例如，可以为一个传输块(或者分别为多个传输块中的每一个)从所述资源子集S A中选择一个或多个资源用于所述传输块的初传或重传，其中，每一个初传或重传可以是一个PSSCH/PSCCH传输(例如PSSCH传输，又如PSCCH传输，又如复用在同一个资源中的PSSCH传输和PSCCH传输)。可选地，在从所述资源子集S A中选择资源时，可以使用“随机选择”的方式，例如，按等概率的方式从所述资源子集S A中随机选择一个资源。 Optionally, in SL resource allocation mode 2, when the UE needs to select (or reselect) resources for initial transmission and/or retransmission for one or more transport blocks to be transmitted, the first The resource subset determination process (or called "the first resource set determination process") determines a resource subset (for example, denoted as resource subset S A , or resource set S A ), and then based on the resource subset S A performs resource selection or resource reselection. For example, one or more resources may be selected from the resource subset SA for a transport block (or each of a plurality of transport blocks) for initial transmission or retransmission of the transport block, wherein, Each initial transmission or retransmission may be a PSSCH/PSCCH transmission (such as PSSCH transmission, or PSCCH transmission, or PSSCH transmission and PSCCH transmission multiplexed in the same resource). Optionally, when selecting resources from the resource subset SA , a "random selection" manner may be used, for example, a resource is randomly selected from the resource subset SA in an equal-probability manner.
可选地，一个特定的触发所述第一资源子集确定过程的方式(例如选择的参数、触发所述第一资源子集确定过程的目的等)和/或所述第一资源子集确定过程的具体执行步骤和/或从所述资源子集S A中选择资源的方式的组合对应一种“资源选择机制”。可选地，若UE在SL资源分配模式2中使用某个资源选择机制，则可以说UE基于该资源选择机制执行SL资源分配模式2。 Optionally, a specific way of triggering the process of determining the first subset of resources (such as selected parameters, the purpose of triggering the process of determining the first subset of resources, etc.) and/or determining the process of the first subset of resources The combination of the specific execution steps of the process and/or the manner of selecting resources from the resource subset SA corresponds to a "resource selection mechanism".

Specifically, for example, if the process of determining the first resource subset is triggered by a high-level entity, the high-level entity may request the physical layer entity to determine a resource subset from which resources can be selected (that is, the resource subset S A ), and the corresponding Specifically, the physical layer entity may report it to the high-level entity after determining the resource subset S A.
可选地，所述第一资源子集确定过程与一个参数集合(例如记为P A)中的参数有关。例如，所述第一资源子集确定过程中的某个步骤使用所述参数集合P A中的一个或多个参数的值。可选地，所述参数集合P A中的部分或全部参数中的每一个可以由所述UE的高层实体确定，或者由所述UE的物理层实体确定，或者是预定义或配置或预配置的值，或者根据一个或多个预定义或配置或预配置的参数确定，或者在触发所述第一资源子集确定过程时提供。 Optionally, the process of determining the first resource subset is related to parameters in a parameter set (for example, denoted as PA ). For example, a certain step in the process of determining the first resource subset uses values of one or more parameters in the parameter set PA . Optionally, each of some or all parameters in the parameter set PA may be determined by a high-level entity of the UE, or determined by a physical layer entity of the UE, or be predefined or configured or pre-configured or determined according to one or more predefined or configured or preconfigured parameters, or provided when the process of determining the first resource subset is triggered.

例如，所述子集

Optionally, in the process of determining the first resource subset, the way to determine the resource subset SA may be to first initialize it as a candidate resource set (for example, the first candidate single-slot resource set) , and then perform zero or one or more exclusion operations on it to obtain the final resource subset S A , wherein, in each exclusion operation, zero or one or more resources are excluded from the current resource subset S A Resources that meet certain conditions. Wherein, the first candidate single-slot resource set may be a set of resources corresponding to L subCH consecutive subchannels in a certain time slot in the resource selection window in the resource pool u (e.g. written as

可选地，所述对集合S A执行的排除操作可以包括下面中的一项或多项： Optionally, the exclusion operation performed on the set SA may include one or more of the following:
●由于所述UE的传输能力限制而无法在其上进行SL传输的资源。例如，由于所述UE支持的同时进行的传输的个数的限制，导致当所述UE在其他载波上进行传输时无法在所述集合S A对应的SL载波上进行SL传输。又如，由于所述UE支持的载波组合的限制导致当所述UE在其他载波上进行传输时无法在所述集合S A对应的SL载波上进行SL传输。又如，由于调谐到所述集合S A中的某个资源所需要的时间的要求超出了所述UE的能力而导致所述UE无法在所述资源进行SL传输。 • Resources on which SL transmission is not possible due to transmission capability limitations of the UE. For example, due to the limitation of the number of simultaneous transmissions supported by the UE, when the UE transmits on other carriers, it cannot perform SL transmission on the SL carrier corresponding to the set SA . For another example, due to the limitation of the combination of carriers supported by the UE, when the UE performs transmission on other carriers, SL transmission cannot be performed on the SL carrier corresponding to the set SA . In another example, because the time required for tuning to a certain resource in the set SA exceeds the capability of the UE, the UE cannot perform SL transmission on the resource.
●所述UE通过感测(sensing)和/或其他操作识别出的满足一定条件的资源(例如，已被其他UE预留的资源)。具体地，例如，通过监听(monitor)或检测(detect)或接收(receive)SL链路上发送的(例如其他UE发送的)资源预留信息(例如SCI中的资源预留信息)，进而确定的已被预留的资源集合和/或无法确定是否已被预留的资源集合和/或可能产生冲突的资源集合和/或已被分配的资源集合和/或不可用于分配的资源集合，等等。可选地，所述“已被其他UE预留的资源”包括SCI中的“资源预留间隔”字段等指示的周期性预留的资源。● Resources that meet certain conditions (for example, resources that have been reserved by other UEs) identified by the UE through sensing and/or other operations. Specifically, for example, by monitoring (monitoring) or detecting (detecting) or receiving (receiving) resource reservation information sent on the SL link (for example, sent by other UEs) (for example, resource reservation information in SCI), and then determine The set of resources that have been reserved and/or the set of resources that cannot be determined to be reserved and/or the set of resources that may cause conflicts and/or the set of resources that have been allocated and/or the set of resources that are not available for allocation, etc. Optionally, the "resources reserved by other UEs" include periodically reserved resources indicated by the "resource reservation interval" field in the SCI.
可选地，在所述第一资源子集确定过程中，确定所述资源子集S A的方 式可以是，先将其初始化为一个空集，然后对其执行零次或一次或多次添加操作后得到最终的资源子集S A，其中，在每一次添加操作中，在当前的资源子集S A中添加零个或一个或多个满足一定条件的资源。 Optionally, in the process of determining the first resource subset, the manner of determining the resource subset S A may be to first initialize it as an empty set, and then perform zero or one or more additions to it After the operation, the final resource subset S A is obtained, wherein, in each adding operation, zero or one or more resources satisfying certain conditions are added to the current resource subset S A .
若一个资源选择机制通过感测操作识别出需要排除的资源，则可以认为该资源选择机制是一种“基于感测的资源选择机制”。其中，感测操作可以是“全感测”(full sensing，或者简称为“感测”，sensing)，例如，UE必须监听感测窗口(例如，时间间隔
Figure PCTCN2022129502-appb-000043
)对应的时间窗口，和/或按其他方式定义的时间窗口)内的属于(或者，可以属于)所述资源池u的、除了因为一些例外情况而无法监听的那些时隙(例如，由于半双工限制而无法在执行SL传输时监听的那些时隙)和/或一些特殊时隙(例如，无法用于传输PSCCH和/或PSSCH的时隙)以外的所有时隙；其中，T 0可以通过高层参数(例如参数sl-SensingWindow)进行配置，
Figure PCTCN2022129502-appb-000044
可以是一个与相应的SL BWP配置的子载波间隔有关的预定义的参数。相应的资源选择机制可以称为“基于全感测的资源选择机制”，或者“基于全感测的资源选择”。 If a resource selection mechanism identifies resources that need to be excluded through a sensing operation, the resource selection mechanism can be considered as a "sensing-based resource selection mechanism". Wherein, the sensing operation may be "full sensing" (full sensing, or simply referred to as "sensing", sensing), for example, the UE must monitor the sensing window (for example, time interval
Figure PCTCN2022129502-appb-000043
) corresponding to the time window, and/or time slots defined in other ways) that belong to (or may belong to) said resource pool u, except for those time slots that cannot be listened to due to some exceptions (for example, due to half Duplex restrictions prevent those time slots that cannot be listened to when performing SL transmissions) and/or all time slots except some special time slots (e.g., time slots that cannot be used to transmit PSCCH and/or PSSCH); where T 0 can be Configured through high-level parameters (such as the parameter sl-SensingWindow),
Figure PCTCN2022129502-appb-000044
May be a predefined parameter related to the subcarrier spacing of the corresponding SL BWP configuration. The corresponding resource selection mechanism may be referred to as a "full-sensing-based resource selection mechanism", or "full-sensing-based resource selection".
感测操作也可以是“部分感测”(partial sensing)，例如，UE只需要监听所述感测窗口内的属于(或者，可以属于)所述资源池u的部分时隙(例如，周期性出现的部分时隙)。相应的资源选择机制可以称为“基于部分感测的资源选择机制”，或者“基于部分感测的资源选择”，或者简称为“部分感测”。The sensing operation may also be "partial sensing", for example, the UE only needs to monitor part of the time slots belonging to (or may belong to) the resource pool u within the sensing window (for example, periodically part of the time slot that occurs). The corresponding resource selection mechanism may be called "resource selection mechanism based on partial sensing", or "resource selection based on partial sensing", or "partial sensing" for short.
若一个资源选择机制不涉及(或者不执行)感测操作，则可以认为该资源选择机制是一种“不基于感测的资源选择机制”。例如，所述资源子 集S A可以等于所述第一候选单时隙资源全集，或者等于在所述第一候选单时隙资源全集中排除一些特殊的资源(例如，无法用于传输PSCCH/PSSCH的时隙中的资源；又如，由于所述UE的传输能力限制而无法在其上进行SL传输的资源)而得到的集合。 If a resource selection mechanism does not involve (or does not perform) a sensing operation, then the resource selection mechanism can be considered as a "non-sensing-based resource selection mechanism". For example, the resource subset S A may be equal to the full set of first candidate single-slot resources, or equal to exclude some special resources (for example, cannot be used to transmit PSCCH/ resources in the time slots of the PSSCH; another example, resources on which SL transmission cannot be performed due to the transmission capability limitation of the UE).
可选地，在不基于感测的资源选择机制中，若UE使用“随机选择”的方式从所述资源子集S A中选择资源(例如，按等概率的方式从所述资源子集S A中随机选择一个资源)，则相应的资源选择机制可以称为“随机资源选择”(random resource selection)，或者简称为“随机选择”(random selection)。 Optionally, in the non-sensing-based resource selection mechanism, if the UE uses a "random selection" method to select resources from the resource subset S A (for example, select resources from the resource subset S A in an equal probability manner Random selection of a resource in A ), the corresponding resource selection mechanism may be called "random resource selection" (random resource selection), or simply "random selection".
在SL通信中(例如在SL资源分配模式2下)可以支持UE间协作(inter-UE coordination)功能，例如，两个或更多个UE之间在资源分配和/或预留和/或指示上进行协作，以提高资源分配和/或预留和/或指示的效率，和/或减少资源分配和/或预留和/或指示的冲突，和/或缓解和/或消除干扰等等。具体地，例如，一个UE(例如，称为UE-A)可以向一个或多个其他UE(例如，若只有一个其他UE，可以称为UE-B；又如，若有多于一个其他UE，可以分别称为UE-B1，UE-B2，......)分别传输“UE间协作信息”(inter-UE coordination information)或“协作信息”(coordination information)，其中，所述协作信息可以显式或隐式地指示(或对应，或关联)一个或多个资源集合(例如称每一个这样的资源集合为一个“协作资源集合”，以及相应地，称一个协作资源集合中的每一个资源为一个“协作资源”)。Inter-UE coordination (inter-UE coordination) functions can be supported in SL communication (e.g. in SL resource allocation mode 2), e.g. resource allocation and/or reservation and/or indication between two or more UEs Collaborate on resources to improve resource allocation and/or reservation and/or indication efficiency, and/or reduce resource allocation and/or reservation and/or indication conflicts, and/or mitigate and/or eliminate interference, and so on. Specifically, for example, a UE (for example, called UE-A) may send a message to one or more other UEs (for example, if there is only one other UE, it may be called UE-B; for another example, if there are more than one other UE , which can be referred to as UE-B1, UE-B2, ...) respectively transmit "inter-UE coordination information" (inter-UE coordination information) or "coordination information" (coordination information), wherein the coordination Information may explicitly or implicitly indicate (or correspond to, or relate to) one or more resource sets (for example, each such resource set is referred to as a "collaborative resource set", and correspondingly, a collaborative resource set is called Each resource is a "collaboration resource").
可选地，一个UE可以支持一个或多个协作方案(coordination scheme)， 其中，在不同的协作方案中，确定协作信息的方式和/或协作信息的内容(特别是协作资源集合的内容)和/或触发协作信息传输的条件和/或传输协作信息的方式等可以不同。Optionally, a UE may support one or more coordination schemes (coordination schemes), wherein, in different coordination schemes, the manner of determining the coordination information and/or the content of the coordination information (especially the content of the coordination resource set) and The condition for triggering the transmission of the cooperation information and/or the manner of transmitting the cooperation information may be different.
可选地，在一个协作方案(例如称为第一协作方案)中，一个协作资源集合中的资源可以是“优先资源”(preferred resources)，相应地，所述协作资源集合可以称为“优先资源集合”，携带一个“优先资源集合”的协作信息可以称为“优先协作信息”(preferred co-ordination information，或者称为“优先UE间协作信息”，preferred inter-UE co-ordination information)。其中，一个由UE-A向UE-B指示的优先资源可以是所述UE-A希望所述UE-B使用(或优先使用)的资源，例如当所述资源用于所述UE-B到所述UE-A(或其他UE)的PSCCH和/或PSSCH传输时，所述UE-A希望所述UE-B优先使用所述资源。所述UE-B在接收到所述优先资源集合后，可以基于一个或多个资源集合执行资源选择或资源重选，例如，所述一个或多个资源集合可以包括所述协作资源集合(例如称为集合
Figure PCTCN2022129502-appb-000045
)，和/或所述UE-B基于自己的感测结果识别出来的资源集合(例如称为集合S SNS)；具体地，例如，若所述集合
Figure PCTCN2022129502-appb-000046
和所述集合S SNS的交集中的资源的个数大于(或者，大于或等于)某个阈值，则所述UE-B基于所述集合
Figure PCTCN2022129502-appb-000047
和所述集合S SNS的交集执行资源选择或资源重选。 Optionally, in a cooperation scheme (for example, called the first cooperation scheme), the resources in a cooperation resource set may be "preferred resources", and correspondingly, the cooperation resource set may be called "preferred resources". Resource set", the cooperation information carrying a "preferred resource set" may be called "preferred co-ordination information" (preferred co-ordination information, or "preferred inter-UE co-ordination information", preferred inter-UE co-ordination information). Wherein, a priority resource indicated by UE-A to UE-B may be a resource that UE-A wants UE-B to use (or preferentially use), for example, when the resource is used for UE-B to When the UE-A (or other UE) transmits the PSCCH and/or PSSCH, the UE-A hopes that the UE-B will use the resource preferentially. After receiving the priority resource set, the UE-B may perform resource selection or resource reselection based on one or more resource sets, for example, the one or more resource sets may include the cooperative resource set (eg called collection
Figure PCTCN2022129502-appb-000045
), and/or the resource set identified by the UE-B based on its own sensing results (for example, called the set S SNS ); specifically, for example, if the set
Figure PCTCN2022129502-appb-000046
The number of resources in the intersection with the set S SNS is greater than (or greater than or equal to) a certain threshold, then the UE-B is based on the set
Figure PCTCN2022129502-appb-000047
The intersection with said set S SNS performs resource selection or resource reselection.
可选地，在所述第一协作方案中，一个协作资源集合中的资源可以是“非优先资源”(non-preferred resources)，相应地，所述协作资源集合可以称为“非优先资源集合”，携带一个“非优先资源集合”的协作信息可以称为“非优先协作信息”(non-preferred co-ordination information， 或者称为“非优先UE间协作信息”，non-preferred inter-UE co-ordination information)。其中，一个由UE-A向UE-B指示的非优先资源可以是所述UE-A希望所述UE-B不要使用(或最好不要使用，或优先排除)的资源，例如当所述资源用于所述UE-B到所述UE-A(或其他UE)的PSCCH和/或PSSCH传输时，所述UE-A希望所述UE-B优先排除所述资源。所述UE-B在接收到所述协作资源集合后，可以基于一个或多个资源集合执行资源选择或资源重选。例如，所述一个或多个资源集合可以包括所述非优先资源集合(例如称为集合
Figure PCTCN2022129502-appb-000048
)，和/或所述UE-B基于自己的感测结果识别出来的资源集合S SNS；具体地，例如，所述UE-B在执行资源选择或资源重选(例如，当基于所述集合S SNS执行资源选择或资源重选)时，可以排除与所述集合

中的资源重叠的资源。 Optionally, in the first cooperation scheme, the resources in a cooperative resource set may be "non-preferred resources", and accordingly, the cooperative resource set may be called a "non-preferred resource set". ", the cooperation information carrying a "non-preferred resource set" can be called "non-preferred co-ordination information" (non-preferred co-ordination information, or "non-preferred inter-UE co-ordination information", non-preferred inter-UE co -ordination information). Wherein, a non-priority resource indicated by UE-A to UE-B may be a resource that UE-A wishes UE-B not to use (or preferably not to use, or preferentially excluded), for example, when the resource When used for PSCCH and/or PSSCH transmission from the UE-B to the UE-A (or other UE), the UE-A hopes that the UE-B will preferentially exclude the resource. After receiving the coordinated resource set, the UE-B may perform resource selection or resource reselection based on one or more resource sets. For example, the one or more sets of resources may include the set of non-preferred resources (eg, referred to as set
Figure PCTCN2022129502-appb-000048
), and/or the resource set S SNS identified by the UE-B based on its own sensing results; specifically, for example, the UE-B is performing resource selection or resource reselection (for example, when based on the set When SNS performs resource selection or resource reselection), it can exclude the set

Resources that overlap resources in .
可选地，所述第一协作方案可以配置或预配置为使能或去使能。当所述第一协作方案配置或预配置为使能时，所述UE-A和/或UE-B启用所述第一协作方案。Optionally, the first cooperation scheme may be configured or preconfigured to be enabled or disabled. When the first cooperation scheme is configured or preconfigured to be enabled, the UE-A and/or UE-B enables the first cooperation scheme.
可选地，协作信息的传输可以由传输所述协作信息的UE根据一个或多个预定义或配置或预配置的条件触发。例如，当UE-A完成向UE-B传输的一个传输块的资源选择或资源重选后，UE-A可以触发向UE-B的协作信息传输。Optionally, the transmission of the cooperation information may be triggered by the UE transmitting the cooperation information according to one or more predefined or configured or preconfigured conditions. For example, after UE-A completes resource selection or resource reselection for a transport block transmitted to UE-B, UE-A may trigger the transmission of cooperation information to UE-B.
可选地，协作信息可以是对“协作请求”(coordination request，或者称为“显式协作请求”，explicit coordination request，或者称为“显式请求”，explicit request)的响应，或者说由所述“协作请求”触发。例如，UE-B向UE-A传输一个协作请求，用于请求一个协作资源集合(例 如，请求一个优先资源集合；又如，请求一个非优先资源集合)；作为对所述协作请求的响应，所述UE-A可以确定一个相应的协作资源集合，并将其包含在协作信息中向所述UE-B传输。Optionally, the coordination information may be a response to a "coordination request" (coordination request, or "explicit coordination request", explicit coordination request, or "explicit request", explicit request), or by the The "Collaboration Request" trigger described above. For example, UE-B transmits a cooperation request to UE-A, which is used to request a set of cooperative resources (for example, requesting a set of priority resources; another example, requesting a set of non-priority resources); as a response to the cooperation request, The UE-A may determine a corresponding set of coordination resources, and include it in the coordination information and transmit it to the UE-B.
