● 若所述通信模式是广播，则所述“目标层二标识符”可以是为所述SL传输对应的广播业务配置的。● If the communication mode is broadcast, the "target layer 2 identifier" may be configured for the broadcast service corresponding to the SL transmission.
取决于上下文，可以用“源标识符”指代“源层一标识符”，或者“源层二标识符”；可以用“目标标识符”指代“目标层一标识符”，或者“目标层二标识符”。例如，在物理层信令中，“源标识符”指的是“源层一标识符”，“目标标识符”指的是“目标层一标识符”。Depending on the context, "source identifier" may be used to refer to "source layer one identifier", or "source layer two identifier"; "target identifier" may be used to refer to "target layer one identifier", or "target Layer 2 identifier". For example, in physical layer signaling, "source identifier" refers to "source layer-identifier", and "destination identifier" refers to "destination layer-identifier".
为方便起见，可以将一个特定的通信模式、“源标识符”以及“目标标识符”的组合称为一个“SL连接”(sidelink connection)；或者，在通信模式明确的情况下，将一个特定的“源标识符”以及“目标标识符”的组合称为一个“SL连接”；或者，对于组播模式，将一个特定的“目标标识符”(例如对应一种业务类型)称为一个“SL连接”；或者，对于广播模式，将一个特定的“目标标识符”(例如对应一种业务类型)称为一个“SL连接”。一个SL连接上可以传输一个或多个TB，每个TB可以对应一个或多个SL传输。For convenience, the combination of a specific communication mode, "source identifier" and "destination identifier" can be called a "sidelink connection" (sidelink connection); or, when the communication mode is clear, a specific The combination of the "source identifier" and "target identifier" is called an "SL connection"; or, for multicast mode, a specific "target identifier" (for example, corresponding to a service type) is called an "SL connection" SL connection"; or, for the broadcast mode, a specific "object identifier" (for example, corresponding to a service type) is called an "SL connection". One or more TBs can be transmitted on one SL connection, and each TB can correspond to one or more SL transmissions.
UE可以通过SCI调度数据的传输。SL操作可以支持“两阶段SCI”(two-stage SCI)，其中第一阶段SCI(1 st-stage SCI)可以包含资源预留和/或资源分配等信息，以便于所有正在监测(monitor)SL链路的UE对于资源预留和/或资源分配情况进行感测(sensing)；第二阶段SCI(2 nd-stage SCI)可以包含其他信息，例如和HARQ反馈相关的信息等。下文中如未 特别说明，在单独提到“SCI”时，在适用的情况下，可以指第一阶段SCI，或者第二阶段SCI，或者第一阶段SCI以及第二阶段SCI。 The UE can schedule data transmission through the SCI. SL operation can support "two-stage SCI" (two-stage SCI), where the first stage SCI (1 st -stage SCI) can contain information such as resource reservation and/or resource allocation, so that all monitoring (monitor) SL The UE on the link senses resource reservation and/or resource allocation; the second-stage SCI (2 nd -stage SCI) may contain other information, such as information related to HARQ feedback. Unless otherwise specified below, when "SCI" is mentioned alone, it may refer to the first-stage SCI, or the second-stage SCI, or the first-stage SCI and the second-stage SCI, where applicable.
第一阶段SCI的格式可以是SCI格式1-A(或者写成“SCI格式1_A”)。下面是SCI格式1-A中可以包含的信息的一些例子：The format of the Phase 1 SCI may be SCI Format 1-A (or written as "SCI Format 1_A"). The following are some examples of information that can be included in SCI Form 1-A:
● 优先级(Priority)。● Priority.
● 频率资源分配(Frequency resource assignment)。● Frequency resource assignment.
● 时间资源分配(Time resource assignment)。● Time resource assignment.
● 资源预留周期(Resource reservation period)。● Resource reservation period.
● DMRS模式(DMRS pattern)。● DMRS pattern (DMRS pattern).
● 第二阶段SCI格式(2 nd-stage SCI format)。 ● The second stage SCI format (2 nd -stage SCI format).
每个第一阶段SCI格式中分配和/或预留和/或指示的资源(例如PSCCH/PSSCH资源)的个数的最大值(例如记为
Figure PCTCN2022090937-appb-000077
)可以是一个高层协议配置或预配置的值(例如通过参数sl-MaxNumPerReserve进行配置或预配置)。其中，所述“分配和/或预留和/或指示的资源”可以包括所述第一阶段SCI格式所对应的PSCCH和/或相应的PSSCH所对应的资源。例如，若所述“频率资源分配”和/或“时间资源分配”对应3个资源，则其中第一个资源可以是所述第一阶段SCI格式所对应的PSCCH和/或相应的PSSCH所对应的资源(例如称为“当前SL传输所对应的资源”)，其余两个资源可以是所述第一阶段SCI格式预留和/或分配的两个可以用于其他SL传输的资源(例如用于同一个传输块在将来的时隙中进行重传时使用的资源)。所述“频率资源分配”字段的大小可以和
Figure PCTCN2022090937-appb-000078
有关。例如，当
Figure PCTCN2022090937-appb-000079
时，所述“频率资源分配”字段的大小是

时，所述“时间资源分配”字段的大小是5比特。又如，当
Figure PCTCN2022090937-appb-000085
时，所述“时间资源分配”字段的大小是9比特。 The maximum number of resources (such as PSCCH/PSSCH resources) allocated and/or reserved and/or indicated in each first-stage SCI format (for example, marked as
Figure PCTCN2022090937-appb-000077
) may be a high-level protocol configuration or preconfigured value (eg, configured or preconfigured through the parameter sl-MaxNumPerReserve). Wherein, the "allocated and/or reserved and/or indicated resources" may include the PSCCH corresponding to the SCI format of the first stage and/or the resources corresponding to the corresponding PSSCH. For example, if the "frequency resource allocation" and/or "time resource allocation" correspond to 3 resources, the first resource may be the PSCCH corresponding to the first-stage SCI format and/or the corresponding PSSCH resources (such as "resources corresponding to the current SL transmission"), and the remaining two resources may be two resources reserved and/or allocated by the SCI format of the first stage and can be used for other SL transmissions (such as using resources used for retransmissions of the same transport block in future slots). The size of the "frequency resource allocation" field can be the same as

, the size of the "time resource allocation" field is 9 bits.
一个第一阶段SCI格式分配和/或预留和/或指示的资源可以是非周期性的。另外，在一定条件下(例如，若参数sl-MultiReserveResource已配置或预配置)，所述第一阶段SCI格式可以通过“资源预留周期”字段指示高层协议参数(例如，sl-ResourceReservePeriodList)配置或预配置的若干个“资源预留周期”(或者说，“资源预留间隔”)中的一个(例如，记所指示的资源预留周期的值为
Figure PCTCN2022090937-appb-000086
)。此时，所述第一阶段SCI可以分配和/或预留和/或指示周期性出现的资源。例如，若所述第一阶段SCI中的“频率资源分配”和/或“时间资源分配”指示的资源中包括时隙
Figure PCTCN2022090937-appb-000087
上的一个资源，则所述第一阶段SCI格式分配和/或预留和/或指示的资源集合中不但包括所述时隙
Figure PCTCN2022090937-appb-000088
上的资源，还包括在时隙

……等上面的对应同样的子信道集合的资源。间隔为
Figure PCTCN2022090937-appb-000091
的两个资源可以用于传输两个不同的TB。 The resources allocated and/or reserved and/or indicated by a first-stage SCI format may be aperiodic. In addition, under certain conditions (for example, if the parameter sl-MultiReserveResource has been configured or pre-configured), the first-stage SCI format can indicate the configuration or One of several pre-configured "resource reservation periods" (or "resource reservation intervals") (for example, note that the value of the resource reservation period indicated is
Figure PCTCN2022090937-appb-000086
). At this time, the first-stage SCI may allocate and/or reserve and/or indicate periodically occurring resources. For example, if the resources indicated by the "frequency resource allocation" and/or "time resource allocation" in the SCI of the first stage include time slots
Figure PCTCN2022090937-appb-000087
A resource on the above, then the resource set allocated and/or reserved and/or indicated by the SCI format in the first stage not only includes the time slot

resources on, also included in the slot

...and the above resources corresponding to the same set of sub-channels. The interval is
Figure PCTCN2022090937-appb-000091
The two resources of can be used to transfer two different TBs.
第二阶段SCI的格式可以是SCI格式2-A(或者写成“SCI格式2_A”)，或者SCI格式2-B(或者写成“SCI格式2_B”)，或者其他SCI格式。下面是SCI格式2-A和/或SCI格式2-B中可以包含的信息的一些例子：The format of the second-stage SCI may be SCI format 2-A (or written as "SCI format 2_A"), or SCI format 2-B (or written as "SCI format 2_B"), or other SCI formats. The following are some examples of information that may be included in SCI Form 2-A and/or SCI Form 2-B:
● 源层一标识符。● Source layer-identifier.
● 目标层一标识符。● Target layer one identifier.
● HARQ进程标识(HARQ Process ID)，或者说HARQ进程号(HARQ Process Number)。● HARQ Process ID (HARQ Process ID), or HARQ Process Number (HARQ Process Number).
● 新数据标识(New Data Indicator，NDI)。● New Data Indicator (NDI).
● 冗余版本(Redundancy Version，RV)。● Redundancy Version (Redundancy Version, RV).
第一阶段SCI可以携带在PSCCH上。第二阶段SCI可以和要传输的数据一起复用在PSCCH关联的(或者说调度的)PSSCH上。PSCCH及其所关联的PSSCH可以通过一定的方式复用在为SL传输分配的时域和/或频域资源上(例如，PSCCH的起始资源块所在的子信道可以是其所关联的PSSCH的起始子信道。又如，PSCCH的起始资源块可以是其所关联的PSSCH的起始子信道的起始资源块)。另外，可以认为第一阶段SCI和/或相应的第二阶段SCI调度了相应的PSSCH(或者说调度了PSSCH的传输，或者说调度了PSSCH中携带的TB的传输)。The first stage SCI can be carried on the PSCCH. In the second stage, the SCI can be multiplexed with the data to be transmitted on the PSSCH associated with the PSCCH (or scheduled). The PSCCH and its associated PSSCH can be multiplexed on the time domain and/or frequency domain resources allocated for SL transmission in a certain way (for example, the subchannel where the starting resource block of the PSCCH is located can be the subchannel of the associated PSSCH The start subchannel. In another example, the start resource block of the PSCCH may be the start resource block of the start subchannel of the associated PSSCH). In addition, it can be considered that the first-stage SCI and/or the corresponding second-stage SCI schedule the corresponding PSSCH (or schedule the transmission of the PSSCH, or schedule the transmission of the TB carried in the PSSCH).
若HARQ反馈已启用，则RX UE可以通过PSFCH反馈与PSCCH和/或PSSCH接收有关的信息(例如称为“HARQ-ACK信息”)。例如，当RX UE在一个资源池中接收一个PSSCH，且相应的SCI中的“HARQ反馈使能/去使能指示符(HARQ feedback enabled/disabled indicator)”字段的值为1时，所述RX UE在所述资源池中通过PSFCH传输提供HARQ-ACK信息。这种HARQ-ACK信息可以称为“在SL上报告的与SL传输有关的HARQ-ACK信息”。在一些配置下，在SL上报告的与SL传输有关的HARQ-ACK信息可以指示肯定应答(ACK，Acknowledgement，或者Positive Acknowledgement)，例如表示可以正确解码相应的PSCCH和/或PSSCH所携带的数据，或者指示否定应答(NACK，或者NAK， Negative Acknowledgement)，例如表示无法正确解码相应的PSCCH和/或PSSCH所携带的数据；在另一些配置下，在SL上报告的与SL传输有关的HARQ-ACK信息可以只指示NACK(例如在可以正确解码相应的PSCCH和/或PSSCH所携带的数据时，不发送任何HARQ反馈；在无法正确解码相应的PSCCH和/或PSSCH所携带的数据时，发送NACK)。“ACK”和“NACK”可以称为HARQ-ACK值(HARQ-ACK value)。If HARQ feedback is enabled, the RX UE may feed back information related to PSCCH and/or PSSCH reception (e.g. called "HARQ-ACK information") via PSFCH. For example, when the RX UE receives a PSSCH in a resource pool, and the value of the "HARQ feedback enabled/disabled indicator (HARQ feedback enabled/disabled indicator)" field in the corresponding SCI is 1, the RX The UE provides HARQ-ACK information through PSFCH transmission in the resource pool. Such HARQ-ACK information may be referred to as "HARQ-ACK information related to SL transmission reported on SL". Under some configurations, the HARQ-ACK information related to SL transmission reported on SL may indicate a positive acknowledgment (ACK, Acknowledgment, or Positive Acknowledgment), for example, indicating that the corresponding PSCCH and/or PSSCH carried data can be correctly decoded, Or indicate a negative acknowledgment (NACK, or NAK, Negative Acknowledgment), for example, indicating that the data carried by the corresponding PSCCH and/or PSSCH cannot be correctly decoded; under other configurations, the HARQ-ACK related to SL transmission reported on SL The information may only indicate NACK (for example, when the data carried by the corresponding PSCCH and/or PSSCH can be correctly decoded, no HARQ feedback is sent; when the data carried by the corresponding PSCCH and/or PSSCH cannot be correctly decoded, NACK is sent) . "ACK" and "NACK" may be referred to as a HARQ-ACK value (HARQ-ACK value).
一个RX UE在进行SL接收时，可以只接收满足SL接收条件的PSCCH和/或PSSCH传输。其中，所述SL接收条件可以包括下面中的一项或多项：When a RX UE is performing SL reception, it can only receive PSCCH and/or PSSCH transmissions that meet the SL reception conditions. Wherein, the SL reception conditions may include one or more of the following:
● 根据SCI确定的源层一标识符和/或目标层一标识符和/或通信模式(例如单播，又如多播，又如广播)的组合与所述RX UE中允许用于接收的源层一标识符和/或目标层一标识符和/或通信模式的一个组合(例如，一个或多个组合中的一个)一致。● Combination of the source layer-identifier and/or target layer-identifier and/or communication mode (such as unicast, multicast, and broadcast) determined according to the SCI and the RX UE allowed for reception A combination (eg, one of one or more combinations) of the source layer-identifier and/or target layer-identifier and/or communication mode agrees.
● 根据SCI和/或相应的MAC PDU子头(subheader)确定的源层二标识符和/或目标层二标识符和/或通信模式与所述RX UE中允许用于接收的源层二标识符和/或目标层二标识符和/或通信模式的一个组合(例如，一个或多个组合中的一个)一致。● The source layer 2 identifier and/or target layer 2 identifier and/or communication mode determined according to the SCI and/or the corresponding MAC PDU subheader (subheader) and the source layer 2 identifier allowed for reception in the RX UE identifier and/or a target layer 2 identifier and/or a communication mode (eg, one of one or more combinations).
在时域(time domain)，PSFCH资源可以在一个资源池中周期性地出现，例如相应的周期(例如称为“PSFCH周期”或者“PSFCH资源周期”，例如记为
Figure PCTCN2022090937-appb-000092
例如单位为时隙个数)可以通过参数periodPSFCHresource(或者参数sl-PSFCH-Period)进行配置，例如配置为
Figure PCTCN2022090937-appb-000093
或者
Figure PCTCN2022090937-appb-000094
或者
Figure PCTCN2022090937-appb-000095
或者
Figure PCTCN2022090937-appb-000096
)。其 中，
Figure PCTCN2022090937-appb-000097
可以用于指示相应的资源池中没有配置PSFCH资源。例如，若一个资源池未配置PSFCH相关的参数(例如参数sl-PSFCH-Config，或者所述参数sl-PSFCH-Config中的一个或多个参数)，或者所述参数sl-PSFCH-Config中配置的PSFCH周期为0，则表示所述资源池未配置PSFCH资源。又如，若一个资源池已配置所述参数sl-PSFCH-Config且所述参数sl-PSFCH-Config中配置的PSFCH周期的值不是0，则表示所述资源池已配置PSFCH资源。 In the time domain (time domain), PSFCH resources may appear periodically in a resource pool, such as a corresponding period (for example, called "PSFCH period" or "PSFCH resource period", for example, denoted as
Figure PCTCN2022090937-appb-000092
For example, the unit is the number of time slots) can be configured through the parameter periodPSFCHresource (or parameter sl-PSFCH-Period), for example, configured as
Figure PCTCN2022090937-appb-000093
or
Figure PCTCN2022090937-appb-000094
or
Figure PCTCN2022090937-appb-000095
or
Figure PCTCN2022090937-appb-000096
). in,
Figure PCTCN2022090937-appb-000097
It can be used to indicate that no PSFCH resource is configured in the corresponding resource pool. For example, if a resource pool is not configured with PSFCH-related parameters (such as the parameter sl-PSFCH-Config, or one or more parameters in the parameter sl-PSFCH-Config), or the parameters configured in the parameter sl-PSFCH-Config If the PSFCH period is 0, it means that the resource pool is not configured with PSFCH resources. As another example, if a resource pool has been configured with the parameter sl-PSFCH-Config and the value of the PSFCH period configured in the parameter sl-PSFCH-Config is not 0, it means that the resource pool has been configured with PSFCH resources.
一个配置了PSFCH资源的时隙可以称为“PSFCH时隙”。在一个PSFCH时隙内，与PSFCH传输有关的符号可以是所述时隙的最后一个或多个SL符号，例如对于PSFCH格式0，符号
Figure PCTCN2022090937-appb-000098
可以用作间隔(GAP)符号，或者保护(GUARD)符号；符号

Figure PCTCN2022090937-appb-000104
可以用于自动增益控制(Automatic Gain Control，AGC)。一个PSFCH时隙的其他SL符号可以用于发送其他SL信号/信道，如PSCCH、PSSCH等。 A time slot configured with PSFCH resources may be called a "PSFCH time slot". Within a PSFCH slot, the symbols related to PSFCH transmission can be the last one or more SL symbols of the slot, for example, for PSFCH format 0, the symbols
Figure PCTCN2022090937-appb-000098
Can be used as a gap (GAP) symbol, or a protection (GUARD) symbol; symbol

Can be used for automatic gain control (Automatic Gain Control, AGC). Other SL symbols in one PSFCH slot can be used to transmit other SL signals/channels, such as PSCCH, PSSCH, etc.
在SL资源分配模式2中，可以使用一种或多种方式确定所分配的SL资源。例如，可以使用不同的方式确定“可用资源”(或者“空闲资源”)的集合，然后从所述“可用资源”(或者“空闲资源”)的集合中选择(例如随机选择)一个或多个SL资源用于SL传输。在本发明的实施例和实施方式中，将确定“可用资源”的集合的方式可以称为“资源选择机制” (resource selection mechanism)，或者“资源选择方法”(resource selection method)，或者“资源选择方案”(resource selection scheme)，或者“资源确定机制”(resource determination mechanism)，或者“资源确定方法”(resource determination method)，或者“资源确定方案”(resource determination scheme)，或者“资源分配机制”(resource allocation mechanism)，或者“资源分配方法”(resource allocation method)，或者“资源分配方案”(resource allocation scheme)，或者为上述名称加上前缀“SL”(例如，“SL资源选择机制”)，等等。或者，将确定所分配的SL资源的所有操作的集合称为“资源选择机制”。或者，将确定所分配的SL资源的部分操作的集合称为“资源选择机制”。In SL resource allocation mode 2, one or more ways may be used to determine the allocated SL resources. For example, different ways can be used to determine the set of "available resources" (or "idle resources"), and then select (for example, randomly select) one or more SL resources are used for SL transmission. In the examples and implementations of the present invention, the way of determining the set of "available resources" can be called "resource selection mechanism", or "resource selection method", or "resource selection method". Selection scheme" (resource selection scheme), or "resource determination mechanism", or "resource determination method", or "resource determination scheme", or "resource allocation mechanism" " (resource allocation mechanism), or "resource allocation method", or "resource allocation scheme", or prefix the above names with "SL" (for example, "SL resource selection mechanism" ),and many more. Alternatively, the set of all operations that determine the allocated SL resources is referred to as a "resource selection mechanism". Alternatively, the set of partial operations that determine the allocated SL resources is referred to as a "resource selection mechanism".
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。If the UE uses a certain resource selection mechanism in the SL resource allocation mode 2, it can be said that the UE executes the SL resource allocation mode 2 based on the resource selection mechanism.
SL资源分配模式2所对应的操作可以包括，由高层协议实体(例如MAC层协议实体)在时隙n向物理层协议实体请求根据一个输入参数集合(例如记为P A)确定一个可以从中选择资源的资源子集(例如记为S A)，并由物理层协议实体向高层协议实体(例如MAC层协议实体)报告所述资源子集S A。 The operation corresponding to the SL resource allocation mode 2 may include that the high-level protocol entity (for example, the MAC layer protocol entity) requests the physical layer protocol entity to determine a set of input parameters (for example, denoted as PA ) from which one can be selected from at time slot n. A resource subset of resources (for example, denoted as SA ), and the physical layer protocol entity reports the resource subset SA to a higher layer protocol entity (for example, the MAC layer protocol entity).
所述输入参数集合P A可以包含下面中的一项或多项： The input parameter set PA may include one or more of the following:
● 用于进行资源选择的资源池(例如记为u sel)。例如，所述资源子集S A可以是所述资源池u sel中的一个候选资源集合的一个子集。 ● A resource pool for resource selection (for example, denoted as u sel ). For example, the resource subset SA may be a subset of a candidate resource set in the resource pool u sel .
● 优先级(例如层一优先级，或者说物理层优先级，例如记为prio TX)。 ● Priority (such as layer one priority, or physical layer priority, such as denoted as prio TX ).
● 剩余分组延迟预算(remaining packet delay budget)。● remaining packet delay budget (remaining packet delay budget).
● 资源的大小。例如，所述“资源的大小”可以包括每一个资源所占用的子信道个数(例如连续的子信道个数)，例如记为L subCH。又如，所述“资源的大小”可以包括每一个资源所占用的时隙个数(例如连续的时隙个数)，例如记为L slot。可选地，L subCH和/或L slot可以是预定义或配置或预配置的值，例如L slot＝1(此时可以称所述资源为单时隙资源，single-slot resource)。 ● The size of the resource. For example, the "resource size" may include the number of sub-channels (eg, the number of consecutive sub-channels) occupied by each resource, for example, denoted as L subCH . As another example, the "resource size" may include the number of time slots (for example, the number of consecutive time slots) occupied by each resource, for example, denoted as L slot . Optionally, L subCH and/or L slot may be predefined or configured or pre-configured values, for example, L slot =1 (in this case, the resource may be called a single-slot resource, single-slot resource).
● 资源预留间隔(resource reservation interval)，例如记为P rsvp_TX。 ● Resource reservation interval (resource reservation interval), for example, it is marked as P rsvp_TX .
● 一个用于重评估(re-evaluation)操作的资源集合，例如记为(r 0，r 1，r 2，...)。 ● A set of resources for re-evaluation operations, eg denoted as (r 0 , r 1 , r 2 , . . . ).
● 一个用于抢占(pre-emption)操作的资源集合，例如记为(r′ 0，r′ 1，r′ 2，...)。 ● A set of resources for pre-emption operations, eg denoted as (r′ 0 , r′ 1 , r′ 2 , . . . ).
为确定所述资源子集S A，可以将集合S A初始化为所有的候选资源组成的集合(例如记为S all)，然后从集合S A中去掉不可用的资源(例如已被其他UE预留的资源)，最后得到的集合S A即为所请求的资源子集。 In order to determine the resource subset SA, the set SA can be initialized as a set composed of all candidate resources (for example, denoted as S all ), and then unavailable resources (for example, reserved by other UEs ) are removed from the set SA. reserved resources), and the finally obtained set S A is the requested resource subset.
所述“所有的候选资源组成的集合S all”可以是资源选择窗口(例如，时间间隔[n+T 1，n+T 2]对应的时间窗口)内的、在所述资源池u sel中的、所有对应L subCH个子信道和L slot个时隙的资源的集合，或者该集合的一个子集(例如，只包含可用于传输PSCCH和/或PSSCH的时隙中的资源。例如，若所述资源池u sel中的某个时隙中配置的SL符号集合中，可以用于传输PSCCH和/或PSSCH的SL符号的个数没有对应的PSSCH DMRS模式，则所述时隙无法用于传输PSCCH和/或PSSCH，从而所述时隙中的资源可以不属于所述集合S all)。其中，T 1和T 2可以是由UE确定的、满 足一定条件的两个数值，例如，T 1可以与UE的处理能力有关，T 2可以与剩余分组延迟预算有关。 The "set S all composed of all candidate resources" may be within the resource selection window (for example, the time window corresponding to the time interval [n+T 1 , n+T 2 ]), in the resource pool u sel A set of resources corresponding to L subCH subchannels and L slot time slots, or a subset of the set (for example, only including resources in time slots that can be used to transmit PSCCH and/or PSSCH. For example, if In the SL symbol set configured in a certain time slot in the resource pool u sel , if the number of SL symbols that can be used to transmit PSCCH and/or PSSCH does not have a corresponding PSSCH DMRS mode, the time slot cannot be used for transmission PSCCH and/or PSSCH, thus resources in the slot may not belong to the set S all ). Wherein, T 1 and T 2 may be two values determined by the UE and satisfy certain conditions, for example, T 1 may be related to the processing capability of the UE, and T 2 may be related to the remaining packet delay budget.
对于一个应用SL资源分配模式2的UE，所述从集合S A中去掉的“不可用的资源”可以包括下面中的一项或多项： For a UE applying SL resource allocation mode 2, the "unavailable resources" removed from 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 cannot be performed due to transmission capability limitations of said 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)操作识别出的不可用的资源。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。● Unavailable resources identified by the UE through a sensing operation. For example, by monitoring (monitoring) or detecting (detecting) or receiving (receiving) resource reservation information sent on the SL link (such as sent by other UEs) (such as resource reservation information in SCI), and then determined to have been A set of reserved resources and/or a set of resources that cannot be determined to be reserved and/or a set of resources that may cause conflicts and/or a set of resources that have been allocated and/or a set of resources that are not available for allocation, etc.
● 其他UE或基站指示的不可用的资源。例如，其他UE通过监听或检测或接收SL链路上发送的资源预留信息(例如SCI中的资源预留信息)，从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和/或非优先分配的资源集合，等等。其他UE可以通过SL传输中携带的信令向所述UE指示与这些资源有关的信息。● Unavailable resources indicated by other UEs or base stations. For example, other UEs monitor or detect or receive the resource reservation information sent on the SL link (for example, the resource reservation information in the SCI), so as to determine the resource set that has been reserved and/or cannot determine whether it has been reserved Reserved resource sets and/or resource sets that may cause conflicts and/or allocated resource sets and/or unavailable resource sets for allocation and/or non-priority allocated resource sets, and so on. Other UEs may indicate information related to these resources to the UE through the signaling carried in the SL transmission.
SL资源分配模式2所对应的操作可以包括，从所述资源子集S A中选择用于一个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)的资源。 The operation corresponding to the SL resource allocation mode 2 may include selecting a PSSCH /PSCCH transmission from the resource subset SA (such as PSSCH transmission, or PSCCH transmission, or PSSCH multiplexed in the same resource) transmission and PSCCH transmission) resources.
SL资源分配模式2所对应的操作可以包括，从所述资源子集S A中选择用于多个PSSCH/PSCCH传输的资源。 The operation corresponding to the SL resource allocation mode 2 may include selecting resources for multiple PSSCH /PSCCH transmissions from the resource subset SA.
SL资源分配模式2所对应的操作可以包括，从所述资源子集S A中选择用于一个传输块的传输资源，例如从所述资源子集S A中选择用于所述传输块的初始传输以及每一次重传所需的资源。 The operation corresponding to the SL resource allocation mode 2 may include selecting a transmission resource used for a transport block from the resource subset SA , for example, selecting an initial resource used for the transport block from the resource subset SA The resources required for transmission and each retransmission.
SL资源分配模式2所对应的操作可以包括，从所述资源子集S A中选择用于多个传输块的传输资源，例如从所述资源子集S A中选择用于所述多个传输块中的每一个传输块的初始传输以及每一次重传所需的资源。 The operation corresponding to the SL resource allocation mode 2 may include selecting transmission resources used for multiple transmission blocks from the resource subset SA , for example, selecting transmission resources used for the multiple transmission blocks from the resource subset SA The resources required for the initial transmission of each transport block in the block and for each retransmission.
在SL资源分配模式2中，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中选择一个资源。 In SL resource allocation mode 2, when selecting resources from the resource subset S A , the "random selection" method can be used, for example, selecting a resource from the resource subset S A in an equal probability manner .
若一个资源选择机制通过感测操作识别出不可用的资源，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 PCTCN2022090937-appb-000105
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 sel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 PCTCN2022090937-appb-000106
可以与UE的处理能力有关。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”，或者简称为“全感测”，或者在不引起混淆的情况下简称为“基于感测的资源选择机制”，或者“基于感测的资源选择”，或者简称为“感测”。 If a resource selection mechanism identifies unavailable resources 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

corresponding time window, and/or time window defined in other ways) belonging to (or, can belong to) said resource pool u sel , except those time slots that cannot be monitored because of 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 PCTCN2022090937-appb-000106
It may be related to the processing capability of the UE. The corresponding resource selection mechanism may be referred to as "full-sensing-based resource selection mechanism", or "full-sensing-based resource selection", or simply "full-sensing", or simply "full-sensing" without causing confusion. Sensing-based resource selection mechanism", or "sensing-based resource selection", or "sensing" for short.
在SL传输(或者“SL通信传输”，sidelink communication transmission)流程中，当需要执行SL传输时，UE先从一个传输资源池集合(例如记为U TX)中确定一个资源池(例如记为

)，然后从所述资源池
Figure PCTCN2022090937-appb-000108
中确定一个SL传输对应的资源。所述传输资源池集合U TX可以与所述UE使用的SL资源分配模式有关；另外，在不同的条件下，同一个SL资源分配模式可以按不同的方式执行，相应地，所述传输资源池集合UTX可以不同。具体地， In the SL transmission (or "SL communication transmission", sidelink communication transmission) process, when SL transmission needs to be performed, the UE first determines a resource pool (for example, denoted as U TX ) from a set of transmission resource pools (denoted as U TX ).

A resource corresponding to an SL transmission is determined in . The transmission resource pool set U TX may be related to the SL resource allocation mode used by the UE; in addition, under different conditions, the same SL resource allocation mode may be executed in different ways, and correspondingly, the transmission resource pool Set UTX can be different. specifically,

SL DRX can be used in various SL scenarios (such as coverage scenarios, partial coverage scenarios, and no coverage scenarios) and various communication modes (such as broadcast, multicast, and unicast).
在SL DRX中，UE(例如当作为RX UE时)在一部分时间(例如称为“激活时间”，active time)内可以执行一项或多项SL接收操作(例如监听或检测或接收第一阶段SCI，又如监听或检测或接收第二阶段SCI，和/或监听或检测或接收PSCCH，又如监听或检测或接收PSSCH，又如监听或检测或接收PSFCH，又如监听或检测或接收S-SSB，又如在一个或多个传输资源池上进行“感测”操作)，其余的时间(例如称为“非激活时间”，inactive time)内可以不执行所述SL接收操作。例如在非激活时间，UE可以在一定条件下(例如在不需要作为TX UE执行SL传输操作时)，进入省电模式，或者进入休眠状态，或者额外地，在一个或多个传输资源池上执行“感测”操作。In SL DRX, UE (for example, when acting as RX UE) can perform one or more SL reception operations (such as listening or detecting or receiving the first phase SCI, another example is to monitor or detect or receive the second stage SCI, and/or monitor or detect or receive PSCCH, another example is to monitor or detect or receive PSSCH, another example is to monitor or detect or receive PSFCH, another example is to monitor or detect or receive S - SSB, such as performing a "sensing" operation on one or more transmission resource pools), the SL receiving operation may not be performed during the rest of the time (for example, called "inactive time", inactive time). For example, during non-activation time, under certain conditions (for example, when it does not need to perform SL transmission operation as a TX UE), the UE enters the power saving mode, or enters the dormant state, or additionally, executes on one or more transmission resource pools "Sensing" operation.
UE(例如当作为RX UE时)可以关联零个或一个或多个SL DRX配置(SL DRX configuration)。其中，每个SL DRX配置可以和一个或多个单播(或组播，或广播)SL连接有关。例如，一个单播SL连接可以去使能SL DRX，或者可以关联(或对应)一个SL DRX配置。又如，一个组播SL连接可以去使能SL DRX。又如，一个广播SL连接可以去使能SL DRX。又如，一个或多个对应同一个服务质量标识符(例如，PQI)的组播SL连接可以去使能SL DRX，或者可以关联一个SL DRX配置。又如，一个或多个对应同一个服务质量标识符的广播SL连接可以去使能SL DRX，或者可以关联一个SL DRX配置。又如，一个或多个对应同一个服务质量标识符的组播或广播SL连接可以去使能SL DRX，或者可以关联一个SL DRX配置。A UE (for example, when acting as a RX UE) can be associated with zero or one or more SL DRX configurations (SL DRX configuration). Wherein, each SL DRX configuration may be related to one or more unicast (or multicast, or broadcast) SL connections. For example, a unicast SL connection may disable SL DRX, or may be associated with (or correspond to) an SL DRX configuration. As another example, SL DRX can be disabled for a multicast SL connection. As another example, a broadcast SL connection can disable SL DRX. As another example, one or more multicast SL connections corresponding to the same quality of service identifier (for example, PQI) may disable SL DRX, or may be associated with an SL DRX configuration. For another example, one or more broadcast SL connections corresponding to the same QoS identifier may disable SL DRX, or may be associated with an SL DRX configuration. As another example, one or more multicast or broadcast SL connections corresponding to the same QoS identifier may disable SL DRX, or may be associated with an SL DRX configuration.
在SL DRX中，RX UE在非激活时间内的省电操作能带来实际好处的前提是相应的TX UE在此期间不执行相应的SL传输操作。所以，对于一个单播(或组播，或广播)SL连接，RX UE和相应的TX UE需要对是否使能SL DRX以及相应的SL DRX配置(若使能SL DRX的话)达成一致。例如，对于一个单播SL连接，RX UE和相应的TX UE可以使用缺省的(或预定义的，或配置的，或预配置的)SL DRX配置，或者通过高层信令协商一个SL DRX配置(例如多个预定义或配置或预配置的SL DRX配置中的一个)，或者通过高层信令协商一个SL DRX配置对应的一个或多个参数。又如，对于一个组播SL连接，TX UE和(一个或多个)RX UE可以分别根据相应的服务质量标识符的值确定同一个SL DRX配置(例如多个预定义或配置或预配置的SL DRX配置中的一个)。 又如，对于一个广播SL连接，TX UE和(一个或多个)RX UE分别根据相应的服务质量标识符的值确定同一个SL DRX配置(例如多个预定义或配置或预配置的SL DRX配置中的一个)。相应地，可以认为TX UE关联了零个或一个或多个SL DRX配置，其中，对于每一个SL DRX配置，TX UE可以限制相应的单播(或组播，或广播)SL连接中的SL传输的时间(例如，只在所述SL DRX配置对应的激活时间内执行相应的SL传输)。In SL DRX, the premise that the power-saving operation of the RX UE during the inactive time can bring practical benefits is that the corresponding TX UE does not perform the corresponding SL transmission operation during this period. Therefore, for a unicast (or multicast, or broadcast) SL connection, the RX UE and the corresponding TX UE need to agree on whether to enable SL DRX and the corresponding SL DRX configuration (if SL DRX is enabled). For example, for a unicast SL connection, the RX UE and the corresponding TX UE can use the default (or predefined, or configured, or pre-configured) SL DRX configuration, or negotiate an SL DRX configuration through high-layer signaling (for example, one of multiple predefined or configured or pre-configured SL DRX configurations), or negotiate one or more parameters corresponding to an SL DRX configuration through high-layer signaling. As another example, for a multicast SL connection, the TX UE and (one or more) RX UEs can respectively determine the same SL DRX configuration (such as multiple predefined or configured or pre-configured one of the SL DRX configurations). As another example, for a broadcast SL connection, the TX UE and (one or more) RX UEs respectively determine the same SL DRX configuration (such as multiple predefined or configured or pre-configured SL DRX configurations) according to the value of the corresponding service quality identifier one of the configurations). Correspondingly, the TX UE can be considered to be associated with zero or one or more SL DRX configurations, where, for each SL DRX configuration, the TX UE can restrict the SL in the corresponding unicast (or multicast, or broadcast) SL connection The time of transmission (for example, the corresponding SL transmission is only performed during the activation time corresponding to the SL DRX configuration).
一个单播SL连接建立后，在TX UE和RX UE成功协商或确定一个SL DRX配置前，所述单播SL连接是否使能SL DRX，或者使用哪个SL DRX配置，也需要TX UE和RX UE达成一致。例如，所述单播SL连接可以处于去使能SL DRX状态(例如，对于所述单播SL连接，所述RX UE一直处于“激活时间”)。又如，所述单播SL连接可以使用一个预定义(或预配置，或配置)的SL DRX配置，例如用于建立所述单播SL连接的广播传输对应的服务质量标识符关联的SL DRX配置，或者，若所述广播传输对应的服务质量标识符未关联SL DRX配置，则所述单播SL连接可以处于去使能SL DRX状态)；又如，所述单播SL连接可以使用其对应的服务质量标识符关联的SL DRX配置，或者，若所述单播SL连接对应的服务质量标识符未关联SL DRX配置，则所述单播SL连接可以处于去使能SL DRX状态。After a unicast SL connection is established, before TX UE and RX UE successfully negotiate or determine an SL DRX configuration, whether the unicast SL connection enables SL DRX, or which SL DRX configuration is used, also requires TX UE and RX UE agree. For example, the unicast SL connection may be in the state of disabling SL DRX (for example, for the unicast SL connection, the RX UE is always in "active time"). As another example, the unicast SL connection may use a predefined (or pre-configured, or configured) SL DRX configuration, for example, the SL DRX associated with the quality of service identifier used to establish the broadcast transmission of the unicast SL connection configuration, or, if the quality of service identifier corresponding to the broadcast transmission is not associated with SL DRX configuration, then the unicast SL connection may be in the state of disabling the SL DRX); for another example, the unicast SL connection may use its The SL DRX configuration associated with the corresponding QoS identifier, or, if the QoS identifier corresponding to the unicast SL connection is not associated with the SL DRX configuration, the unicast SL connection may be in a state of disabling SL DRX.
一个SL DRX配置对应的参数可以包括下面中的一项或多项：The parameters corresponding to an SL DRX configuration can include one or more of the following:
● SL DRX周期(SL DRX cycle)相关的参数，例如SL DRX长周期(例如用参数sl-drx-LongCycle配置)，又如SL DRX短周 期(例如用参数sl-drx-ShortCycle配置)，又如一个SL DRX周期的起始位置(例如用参数sl-drx-StartOffset配置)。对所述SL DRX配置，一段长度为SL DRX周期的时间可以周期性地出现，其中部分时间内RX UE处于激活时间，其余时间内RXUE处于非激活时间。SL DRX可以只支持SL DRX长周期，或者只支持SL DRX短周期，或者支持SL DRX长周期和SL DRX短周期。● SL DRX cycle (SL DRX cycle) related parameters, such as SL DRX long cycle (for example, configure with parameter sl-drx-LongCycle), and SL DRX short cycle (for example, configure with parameter sl-drx-ShortCycle), and for example The starting position of an SL DRX cycle (for example, configured with the parameter sl-drx-StartOffset). For the SL DRX configuration, a period of time whose length is the SL DRX cycle may appear periodically, wherein the RX UE is in the active time for part of the time, and the RX UE is in the inactive time for the rest of the time. SL DRX can only support SL DRX long cycle, or only support SL DRX short cycle, or support SL DRX long cycle and SL DRX short cycle.
● “ON持续时间”(ON duration)相关的参数，例如ON持续时间定时器的长度(例如用参数sl-drx-onDurationTimer配置)，又如。其中，ON持续时间可以是从一个SL DRX周期的起始位置偏移一段时间(例如将相应的偏移的长度称为“时隙偏移”，例如用参数sl-drx-SlotOffset配置)后开始的一段可以用于进行一项或多项SL接收操作的时间。● Parameters related to "ON duration", such as the length of the ON duration timer (for example, configured with the parameter sl-drx-onDurationTimer), and for example. Among them, the ON duration can be offset from the starting position of an SL DRX cycle for a period of time (for example, the length of the corresponding offset is called "slot offset", for example configured with the parameter sl-drx-SlotOffset) A period of time that can be used for one or more SL receive operations.
● 非激活时间相关的参数，例如非激活时间定时器的长度(例如用参数sl-drx-InactivityTimer配置)。所述非激活时间定时器可以在满足一定的条件时启动，例如，在接收到一个满足一定条件的SCI(例如，SCI中指示的“源标识符”和/或“目标标识符”和/或“通信模式”所对应的单播或组播或广播SL连接匹配相应的SL DRX配置；又如，SCI指示一个新的TB的传输)后启动。● Parameters related to the inactivity time, such as the length of the inactivity time timer (for example, configured with the parameter sl-drx-InactivityTimer). The inactive time timer may be started when a certain condition is met, for example, upon receiving an SCI that meets a certain condition (for example, the "source identifier" and/or "target identifier" indicated in the SCI and/or The unicast or multicast or broadcast SL connection corresponding to the "communication mode" matches the corresponding SL DRX configuration; for another example, the SCI indicates the transmission of a new TB) and then starts.
UE(例如当作为RX UE时)的激活时间可以包括其关联的每个SL DRX配置(或者，每个已使能的SL DRX配置)对应的激活时间。The activation time of the UE (for example, when acting as a RX UE) may include an activation time corresponding to each SL DRX configuration associated with it (or, each enabled SL DRX configuration).
UE可以配置为“使能SL DRX”，或者配置为“去使能SL DRX”。若UE未配置为“使能SL DRX”，可以认为UE已去使能SL DRX。其中，“使能SL DRX”可以对应下面中的一项：The UE can be configured to "enable SL DRX" or "disable SL DRX". If the UE is not configured to "enable SL DRX", it can be considered that the UE has disabled SL DRX. Among them, "Enable SL DRX" can correspond to one of the following:
● 只使能SL DRX对应的与TX UE有关的操作(例如，对一个给定的SL DRX配置，只在相应的RX UE的激活时间执行SL传输)。此时，所述UE作为TX UE时，可以支持相应的RX UE在SL链路上实现“不连续接收”；但是所述UE作为RX UE时，无法在SL链路上实现“不连续接收”。● Only enable TX UE-related operations corresponding to SL DRX (for example, for a given SL DRX configuration, only perform SL transmission during the activation time of the corresponding RX UE). At this time, when the UE is a TX UE, it can support the corresponding RX UE to implement "discontinuous reception" on the SL link; but when the UE is a RX UE, it cannot implement "discontinuous reception" on the SL link .
● 只使能SL DRX对应的与RX UE有关的操作(例如，对一个给定的SL DRX配置，在激活时间内执行一项或多项SL接收操作；又如，对一个给定的SL DRX配置，在非激活时间内不执行所述一项或多项SL接收操作)。此时，所述UE作为RX UE时，可以在SL链路上实现“不连续接收”；但是所述UE作为TX UE时，无法支持相应的RX UE在SL链路上实现“不连续接收”。● Only enable the RX UE-related operations corresponding to SL DRX (for example, for a given SL DRX configuration, perform one or more SL reception operations within the activation time; another example, for a given SL DRX configuration, the one or more SL receiving operations are not performed during the inactive time). At this time, when the UE acts as a RX UE, it can implement "discontinuous reception" on the SL link; but when the UE acts as a TX UE, it cannot support the corresponding RX UE to implement "discontinuous reception" on the SL link .
● 同时使能SL DRX对应的与TX UE有关的操作(例如，对一个给定的SL DRX配置，只在相应的RX UE的激活时间执行SL传输)和与RX UE有关的操作(例如，对一个给定的SL DRX配置，在激活时间内执行一项或多项SL接收操作；又如，对一个给定的SL DRX配置，在非激活时间内不执行所述一项或多项SL接收操作)。此时，所述UE作为RX UE时，可以在SL链路上实现“不连续接收”；所述UE作为TX UE时，可以支 持相应的RX UE在SL链路上实现“不连续接收”。● Simultaneously enable TX UE-related operations corresponding to SL DRX (for example, for a given SL DRX configuration, perform SL transmission only during the activation time of the corresponding RX UE) and RX UE-related operations (for example, For a given SL DRX configuration, one or more SL reception operations are performed during the activation time; for another example, for a given SL DRX configuration, the one or more SL reception operations are not performed during the inactive time operate). At this time, when the UE is used as a RX UE, it can implement "discontinuous reception" on the SL link; when the UE is used as a TX UE, it can support the corresponding RX UE to implement "discontinuous reception" on the SL link.
相应地，“去使能SL DRX”可以只去使能SL DRX对应的与TX UE有关的操作，或者只去使能SL DRX对应的与RX UE有关的操作，或者同时去使能SL DRX对应的与TX UE有关的操作和与RX UE有关的操作。Correspondingly, "Disable SL DRX" can only enable SL DRX corresponding to TX UE-related operations, or only enable SL DRX corresponding to RX UE-related operations, or simultaneously disable SL DRX corresponding to Operations related to TX UE and operations related to RX UE.
一个单播SL连接对应的两个UE可以查询对方的UE能力，例如通过SL UE能力传输(Sidelink UE capability transfer)流程实现，其中一个UE(例如称为UE A)可以向另一个UE(例如称为UE B)传输UECapabilityEnquirySidelink消息，其中可以包含所述UE A的UE能力；所述UE B可以回应UECapabilityInformationSidelink消息，其中包含所述UE B的UE能力。其中，所述UECapabilityEnquirySidelink消息中包含的UE能力或者UECapabilityInformationSidelink消息中包含的关于SL DRX的UE能力可以包含下面中的一项，或者是下面中多项的组合(在适用的情况下)：Two UEs corresponding to a unicast SL connection can query each other's UE capabilities, for example, through the SL UE capability transfer (Sidelink UE capability transfer) process, where one UE (for example, UE A) can send another UE (for example, UE A) For UE B), transmit a UECapabilityEnquirySidelink message, which may include the UE capability of the UE A; the UE B may respond to a UECapabilityInformationSidelink message, which includes the UE capability of the UE B. Wherein, the UE capability included in the UECapabilityEnquirySidelink message or the UE capability about SL DRX included in the UECapabilityInformationSidelink message may include one of the following, or a combination of multiple items below (where applicable):
● 不支持(或者，不使能)SL DRX对应的与TX UE有关的操作。● Do not support (or not enable) TX UE-related operations corresponding to SL DRX.
● 支持(或者，使能)SL DRX对应的与TX UE有关的操作。● Support (or enable) TX UE-related operations corresponding to SL DRX.
● 不支持(或者，不使能)SL DRX对应的与RX UE有关的操作。● Do not support (or not enable) the operations related to RX UE corresponding to SL DRX.

For example, this indicates that the operation related to the TX UE corresponding to the SL DRX is not supported (or not enabled), and the operation related to the RX UE corresponding to the SL DRX is not supported (or not enabled).
● 支持(或者，使能)SL DRX。例如，这表示支持(或者，使能)SL DRX对应的与TX UE有关的操作，并且支持(或者，使能) SL DRX对应的与RX UE有关的操作。● Support (or enable) SL DRX. For example, this means supporting (or enabling) TX UE-related operations corresponding to SL DRX, and supporting (or enabling) SL DRX-corresponding RX UE-related operations.
一个资源池可以配置为“使能SL DRX”，或者配置为“去使能SL DRX”。例如，在所述资源池的配置信息(例如，信息元素SL-ResourcePool-r16；又如，信息元素SL-ResourcePool-r17)中，通过一个参数(例如sl-DRX-enabled-in-pool，又如sl-DRX-disabled-in-pool)指示相应的资源池是否已使能SL DRX(例如，所述参数sl-DRX-enabled-in-pool的一个取值表示相应的资源池已使能SL DRX；又如，所述参数sl-DRX-enabled-in-pool的一个取值表示相应的资源池未使能SL DRX；又如，所述参数sl-DRX-disabled-in-pool的一个取值表示相应的资源池未使能SL DRX；又如，所述参数sl-DRX-disabled-in-pool的一个取值表示相应的资源池已使能SL DRX)。可选地，若所述参数sl-DRX-enabled-in-pool不存在，则表示相应的资源池未使能SL DRX。可选地，若所述参数sl-DRX-disabled-in-pool不存在，则表示相应的资源池已使能SL DRX。可选地，不支持SL DRX的UE和/或未配置SL DRX的UE可以忽略所述参数sl-DRX-enabled-in-pool(或所述参数sl-DRX-disabled-in-pool)。可选地，不支持SL DRX的UE和/或未配置SL DRX的UE可以忽略所述信息元素SL-ResourcePool-r17配置的资源池。可选地，不支持SL DRX的UE和/或未配置SL DRX的UE可以将所述信息元素SL-ResourcePool-r16配置的传输资源池作为自己的传输资源池。可选地，已配置SL DRX的UE可以将所述信息元素SL-ResourcePool-r16配置的传输资源池和所述信息元素SL-ResourcePool-r17配置的传输资源池都作为自己的传输资源池。A resource pool can be configured as "enable SL DRX" or "disable SL DRX". For example, in the configuration information of the resource pool (for example, information element SL-ResourcePool-r16; another example, information element SL-ResourcePool-r17), a parameter (for example, sl-DRX-enabled-in-pool, and Such as sl-DRX-disabled-in-pool) indicates whether the corresponding resource pool has enabled SL DRX (for example, a value of the parameter sl-DRX-enabled-in-pool indicates that the corresponding resource pool has enabled SL DRX; as another example, a value of the parameter sl-DRX-enabled-in-pool indicates that the corresponding resource pool does not enable SL DRX; as another example, a value of the parameter sl-DRX-disabled-in-pool The value indicates that the corresponding resource pool has not enabled SL DRX; for another example, a value of the parameter sl-DRX-disabled-in-pool indicates that the corresponding resource pool has enabled SL DRX). Optionally, if the parameter sl-DRX-enabled-in-pool does not exist, it means that the corresponding resource pool is not enabled with SL DRX. Optionally, if the parameter sl-DRX-disabled-in-pool does not exist, it means that the corresponding resource pool has enabled SL DRX. Optionally, the UE that does not support SL DRX and/or the UE that is not configured with SL DRX may ignore the parameter sl-DRX-enabled-in-pool (or the parameter sl-DRX-disabled-in-pool). Optionally, a UE that does not support SL DRX and/or a UE that is not configured with SL DRX may ignore the resource pool configured by the information element SL-ResourcePool-r17. Optionally, a UE that does not support SL DRX and/or a UE that is not configured with SL DRX may use the transmission resource pool configured by the information element SL-ResourcePool-r16 as its own transmission resource pool. Optionally, the UE configured with SL DRX may use both the transmission resource pool configured by the information element SL-ResourcePool-r16 and the transmission resource pool configured by the information element SL-ResourcePool-r17 as its own transmission resource pool.
一个资源池集合可以配置为使能SL DRX(即所述资源池集合中的所有资源池都使能SL DRX)，或者配置为去使能SL DRX(即所述资源池集合中的所有资源池都去使能SL DRX)。例如，在与所述资源池集合有关的配置信息中，通过一个参数(例如sl-DRX-enabled-in-poolset，又如sl-DRX-disabled-in-poolset)指示相应的资源池集合是否已使能SL DRX(例如，所述参数sl-DRX-enabled-in-poolset的一个取值表示相应的资源池集合中的所有资源池已使能SL DRX；又如，所述参数sl-DRX-enabled-in-poolset的一个取值表示相应的资源池集合中的所有资源池未使能SL DRX；又如，所述参数sl-DRX-disabled-in-poolset的一个取值表示相应的资源池集合中的所有资源池未使能SL DRX；又如，所述参数sl-DRX-disabled-in-poolset的一个取值表示相应的资源池集合中的所有资源池已使能SL DRX)。可选地，若所述参数sl-DRX-enabled-in-poolset不存在，则表示相应的资源池集合中的所有资源池未使能SL DRX。可选地，若所述参数sl-DRX-disabled-in-poolset不存在，则表示相应的资源池集合中的所有资源池已使能SL DRX。可选地，不支持SL DRX的UE可以忽略所述参数sl-DRX-enabled-in-poolset(或所述参数sl-DRX-disabled-in-poolset)。A resource pool set can be configured to enable SL DRX (that is, all resource pools in the resource pool set enable SL DRX), or configured to disable SL DRX (that is, all resource pools in the resource pool set both to enable SL DRX). For example, in the configuration information related to the resource pool set, a parameter (such as sl-DRX-enabled-in-poolset, or sl-DRX-disabled-in-poolset) is used to indicate whether the corresponding resource pool set has Enable SL DRX (for example, a value of the parameter sl-DRX-enabled-in-poolset indicates that all resource pools in the corresponding resource pool set have enabled SL DRX; another example, the parameter sl-DRX- A value of enabled-in-poolset indicates that all resource pools in the corresponding resource pool set do not enable SL DRX; as another example, a value of the parameter sl-DRX-disabled-in-poolset indicates that the corresponding resource pool All resource pools in the set are not enabled with SL DRX; for another example, a value of the parameter sl-DRX-disabled-in-poolset indicates that all resource pools in the corresponding resource pool set have enabled SL DRX). Optionally, if the parameter sl-DRX-enabled-in-poolset does not exist, it means that all resource pools in the corresponding resource pool set are not enabled with SL DRX. Optionally, if the parameter sl-DRX-disabled-in-poolset does not exist, it means that all resource pools in the corresponding resource pool set have enabled SL DRX. Optionally, the UE that does not support SL DRX may ignore the parameter sl-DRX-enabled-in-poolset (or the parameter sl-DRX-disabled-in-poolset).
SL链路(或者SL载波，或者SL BWP)可以配置为“使能SL DRX”，或者配置为“去使能SL DRX”。若SL链路(或者SL载波，或者SL BWP)未配置为“使能SL DRX”，可以认为所述SL链路(或者SL载波，或者SL BWP)已去使能SL DRX。若SL链路(或者SL载波，或者SL BWP)已去使能SL DRX，则可以认为基于所述SL链路(或者SL载波，或者 SL BWP)的所有SL通信以及相关的实体(例如所有相关的UE，又如所有相关的传输资源池，又如所有相关的接收资源池，又如所有相关的单播SL连接和/或组播SL连接和/或广播SL连接)都已去使能SL DRX。The SL link (or SL carrier, or SL BWP) can be configured as "enable SL DRX" or "disable SL DRX". If the SL link (or SL carrier, or SL BWP) is not configured to "enable SL DRX", it can be considered that the SL link (or SL carrier, or SL BWP) has been disabled to enable SL DRX. If the SL link (or SL carrier, or SL BWP) has disabled SL DRX, it can be considered that all SL communications based on the SL link (or SL carrier, or SL BWP) and related entities (such as all related UEs, such as all relevant transmission resource pools, such as all relevant receiving resource pools, such as all relevant unicast SL connections and/or multicast SL connections and/or broadcast SL connections) have disabled SL DRX.
SL DRX功能需要解决的一个问题是不支持(或未配置)SL DRX的UE如何与支持(或已配置)SL DRX的UE之间进行SL通信。对于单播SL连接，已配置SL DRX的UE可以查询另一个UE是否已配置SL DRX，若对方未配置SL DRX则可以对相应的SL连接去使能SL DRX。问题是，这种方法只适用于单播SL连接，而且，对于一个RX UE，“去使能”其关联的一个SL连接的SL DRX可能意味着对于所述SL连接，所述RX UE需要一直处于激活时间，这使得在所述SL连接终止前，所述RX UE一直处于激活时间(即使所述RX UE的其他SL连接都使能了SL DRX)，即在此期间所述UE完全失去了“不连续接收”带来的省电增益。One problem that the SL DRX function needs to solve is how to perform SL communication between a UE that does not support (or is not configured) SL DRX and a UE that supports (or is configured) SL DRX. For a unicast SL connection, a UE configured with SL DRX can query whether another UE has configured SL DRX. If the other UE has not configured SL DRX, it can disable SL DRX for the corresponding SL connection. The problem is that this approach only works for unicast SL connections, and, for an RX UE, "disabling" SL DRX for one of its associated SL connections may mean that for that SL connection, the RX UE needs to always In the active time, this makes the RX UE always in the active time before the SL connection is terminated (even if the other SL connections of the RX UE are enabled with SL DRX), that is, the UE completely loses DRX during this period The power saving gain brought by "discontinuous reception".
为解决上述问题中的至少一部分，对已使能SL DRX的UE，一些与SL有关的配置(例如资源池配置)和/或一部分SL传输行为和/或一部分SL接收行为需要视SL DRX相关的配置和/或UE状态等的不同而有所不同，例如，如下面中的一项或多项所描述：In order to solve at least part of the above problems, for UEs that have enabled SL DRX, some SL-related configurations (such as resource pool configurations) and/or some SL transmission behaviors and/or some SL reception behaviors need to be SL DRX-related Varies depending on configuration and/or UE state, etc., e.g., as described by one or more of the following:
● 在发送端，未使能SL DRX的SL连接中的SL传输可以限制在一个“未使能SL DRX”的传输资源池子集内。其中，导致一个SL连接未使能SL DRX的原因可以包括，相应的SL链路(或者SL载波，或者SL BWP)未使能SL DRX，和/或所述SL连接未使能SL DRX，和/或相应的TX UE未使能SL DRX(例如，未使能SL DRX中与TX UE有关的操作)，和/或相应的RX UE 未使能SL DRX(例如，未使能SL DRX中与RX UE有关的操作)，和/或(对单播SL连接)相应的TX UE和RX UE未成功协商一个SL DRX配置，和/或(对组播连接)相应的服务质量标识符未对应任何SL DRX配置，和/或(对广播连接)相应的服务质量标识符未对应任何SL DRX配置。● At the sending end, the SL transmission in the SL connection without SL DRX can be limited to a subset of transmission resource pool "without SL DRX". Wherein, the reason causing an SL connection not enabling SL DRX may include that the corresponding SL link (or SL carrier, or SL BWP) is not enabling SL DRX, and/or the SL connection is not enabling SL DRX, and /or the corresponding TX UE is not enabled with SL DRX (for example, the operation related to TX UE in SL DRX is not enabled), and/or the corresponding RX UE is not enabled for SL DRX (for example, the operation related to SL DRX is not enabled in SL DRX RX UE-related operations), and/or (for unicast SL connections) the corresponding TX UE and RX UE did not successfully negotiate an SL DRX configuration, and/or (for multicast connections) the corresponding QoS identifier does not correspond to any SL DRX configuration, and/or (for broadcast connections) the corresponding QoS identifier does not correspond to any SL DRX configuration.
● 在发送端，已使能SL DRX的SL连接中的SL传输可以配置“已使能SL DRX”的传输资源池子集和/或“未使能SL DRX”的传输资源池子集。其中，前者可以用于已使能SL DRX的SL连接对应的SL传输，后者可以用于未使能SL DRX的SL连接对应的SL传输。● At the sending end, the SL transmission in the SL connection with SL DRX enabled can be configured with the "SL DRX enabled" transmission resource pool subset and/or the "SL DRX not enabled" transmission resource pool subset. Among them, the former can be used for SL transmission corresponding to the SL connection with SL DRX enabled, and the latter can be used for SL transmission corresponding to the SL connection without SL DRX enabled.
● 在接收端，对“未使能SL DRX”的接收资源池子集不应用“不连续接收”，即，在激活时间和非激活时间都监听“未使能SLDRX”的接收资源池子集中的资源池，或者，若一个时隙属于“未使能SL DRX”的接收资源池子集中的任意一个(或多个)资源池，则监听所述时隙，或者将所述时隙加入到激活时间中。● At the receiving end, "discontinuous reception" is not applied to the subset of the receiving resource pool "without SLDRX enabled", that is, the resources in the subset of the receiving resource pool "without SLDRX enabled" are monitored at both the activation time and the inactive time pool, or, if a time slot belongs to any one (or more) resource pools in the receiving resource pool subset of "not enabled SL DRX", monitor the time slot, or add the time slot to the activation time .
● 在接收端，对“已使能SL DRX”的接收资源池子集应用“不连续接收”，即，在激活时间监听“已使能SL DRX”的接收资源池子集中的资源池，在非激活时间不监听“已使能SL DRX”的接收资源池子集中的资源池。● At the receiving end, apply “discontinuous reception” to the subset of receiving resource pools of “SL DRX enabled”, that is, monitor the resource pools in the subset of receiving resource pools of “SL DRX enabled” at the activation time, and Time does not listen to resource pools in the "SL DRX enabled" receive resource pool subset.
图1示出了未配置SL DRX的UE与已配置SL DRX的UE之间可以进行SL通信的一个例子。其中，Figure 1 shows an example of SL communication between a UE not configured with SL DRX and a UE configured with SL DRX. in,
● 传输资源池TX#1、TX#2、TX#3和TX#4分别与接收资源池 RX#1、RX#2、RX#3、RX#4对应相同的时间和/或频率资源。● The transmission resource pools TX#1, TX#2, TX#3, and TX#4 correspond to the same time and/or frequency resources as the reception resource pools RX#1, RX#2, RX#3, and RX#4 respectively.
● 已使能SL DRX的UE(例如作为TX UE时)配置了传输资源池TX#1，TX#2，TX#3和TX#4。其中，传输资源池TX#1和TX#2配置为使能SL DRX，用于已使能SL DRX的SL连接对应的SL传输，传输资源池TX#3和TX#4配置为不使能SL DRX，用于未使能SL DRX的SL连接对应的SL传输。● UEs that have enabled SL DRX (for example, as TX UEs) are configured with transmission resource pools TX#1, TX#2, TX#3, and TX#4. Among them, the transmission resource pools TX#1 and TX#2 are configured to enable SL DRX for SL transmission corresponding to the SL connection that has enabled SL DRX, and the transmission resource pools TX#3 and TX#4 are configured to disable SL DRX, used for SL transmission corresponding to the SL connection without SL DRX enabled.
● 未使能SL DRX的UE(例如作为TX UE时)配置了传输资源池TX#3和TX#4。未使能SL DRX的UE可以忽略关于一个传输资源池是否使能SL DRX的配置(若存在的话)。● UEs without SL DRX enabled (for example, as TX UEs) are configured with transmission resource pools TX#3 and TX#4. A UE not enabled with SL DRX may ignore the configuration of whether SL DRX is enabled for a transmission resource pool (if it exists).
● 所有的UE都配置了接收资源池RX#1，RX#2，RX#3和RX#4。其中，RX#1和RX#2配置为使能SL DRX，RX#3和RX#4配置为不使能SL DRX。未使能SL DRX的UE可以忽略关于一个接收资源池是否使能SL DRX的配置。● All UEs are configured with receiving resource pools RX#1, RX#2, RX#3 and RX#4. Among them, RX#1 and RX#2 are configured to enable SL DRX, and RX#3 and RX#4 are configured to disable SL DRX. UEs that do not enable SL DRX can ignore the configuration of whether SL DRX is enabled for a receiving resource pool.
● 未使能SL DRX的UE(例如作为RX UE时)监听属于RX#1或RX#2或RX#3或RX#4的任意一个时隙。● A UE that does not enable SL DRX (for example, when it is a RX UE) monitors any time slot belonging to RX#1 or RX#2 or RX#3 or RX#4.
● 已使能SL DRX的UE(例如作为RX UE时)在激活时间监听属于RX#1或RX#2或RX#3或RX#4的任意一个时隙，在非激活时间监听属于RX#3或RX#4的任意一个时隙。● A UE with SL DRX enabled (for example, as a RX UE) listens to any time slot belonging to RX#1 or RX#2 or RX#3 or RX#4 during the active time, and listens to any time slot belonging to RX#3 during the inactive time Or any time slot of RX#4.
