在未来通信***中,非授权频段(unlicensed band)可以作为授权频段(licensed band)的补充帮助运营商对服务进行扩容。为了与新空口(New Radio,NR)部署保持一致并尽可能的最大化基于NR的非授权接入,非授权频段可以工作在5GHz、37GHz和60GHz频段。非授权频段的大带宽(80MHz或者100MHz)能够减小基站和终端(User Equipment,UE)的实施复杂度。由于非授权频段由多种无线接入技术(Radio Access Technology,RAT)共用,例如WiFi、雷达、长期演进(Long Term Evolution,LTE)授权频谱辅助接入(Licensed-Assisted Access,LAA)等,因此在某些国家或者区域,非授权频段在使用时必须符合法规(regulation)以保证所有设备可以公平的使用该资源,例如,先听后说(listen before talk,LBT)、最大信道占用时间(maximum channel occupancy time,MCOT)等规则。当传输节点需要发送信息是,需要先做LBT时,对周围的节点进行功率检测(energy detection,ED),当检测到的功率低于一个门限时,认为信道为空(idle),传输节点可以进行发送。反之,则认为信道为忙,传输节点不能进行发送。传输节点可以是基站,UE,WiFi AP等等。传输节点开始传输后,占用的信道时间COT不能超过MCOT。此外,根据occupied channel bandwidth(OCB)regulation,在非授权频段上,传输节点在每次传输时要占用整个频带的至少70%(60GHz)或者80%(5GHz)的带宽。
其中,常用的LBT的类型(type)可以分为类型1(Type1)、类型2(Type2)。Type2还包含了Type2A、Type2B和Type2C。Type1LBT是基于回退(back-off)的信道侦听机制,当传输节点侦听到信道为忙时,进行回退,继续做侦听,直到侦听到信道为空。Type2C是发送节点不做LBT,即no LBT或者立即传输(immediate transmission)。Type2、Type2A和Type2B LBT是一次性的(one-shot)LBT,即节点在传输前做一次LBT,信道为空则进行传输,信道为忙则不传输。
在相关技术中,基站(例如,演进型B节点(evolved Node B,eNB)/下一代基站(the next Generation Node B,gNB))可以根据节点自身下行链路信道接入,或UE的上行链
路信道接入发起信道占用(Channel Occupancy)。eNB/gNB/UE可以通过信道接入优先级等级(Channel access priority class,CAPC)确定一个最大的信道占用时间(Channel Occupancy Time,COT)。当eNB/gNB通过Type1信道接入方式接入信道获得CO后,可以指示UE与自己共享这段信道占用(Channel Occupancy,CO)称之为COT共享(sharing)。另外,当UE通过Type1信道接入方式接入信道获得CO后,可以指示eNB/gNB与自己共享这段CO,也称之为COT sharing。
在旁链路(sidelink,SL,也可以称为副链路、侧链路或边链路等)传输中引入非授权频段时,UE可以通过信道接入进程接入信道获得信道占用,然而,在UE进程中的信道接入进程进行旁链路传输时,可能会接收到其它设备(例如,基站或对端UE)发送的旁链路资源信息,例如,基站或对端UE共享抢占到的信道占用等,在这种情况下,UE如何处理进行中的信道接入进程是相关技术中需要解决的技术问题。

下面结合附图,通过一些实施例及其应用场景对本申请实施例提供的信道接入进程的处理方案进行详细地说明。
图2示出本申请实施例中的信道接入进程的处理方法的一种流程示意图,该方法200可以由第一终端执行。换言之,所述方法可以由安装在第一终端上的软件或硬件来执行。如图2所示,该方法可以包括以下步骤。
S210,第一终端在执行第一类型的第一信道接入进程的过程中,获取SL资源信息,其中,所述第一信道接入进程用于进行与第二终端之间的SL传输。
在本申请实施例中,第一类型的第一信道接入进程可以为类型1(Type1),即第一信道接入进程为Type1LBT进程,也就是说,第一终端针对与第二终端之间的SL传输,侦听信道,以获取SL传输的资源。因此,本申请实施例中的第一终端可以为一个在非授权频谱中以type 1LBT方式接入信道的终端,可以称之为发起UE(initiator UE)。
S220,基于所述SL资源信息,所述第一终端执行目标操作。
其中,所述目标操作包括以下之一:
保持(maintain)所述第一信道接入进程;例如,第一终端使用所述第一信道接入进程传输部分或全部SL传输信息。
切换(switch)到第二类型的第二信道接入进程;例如,第一终端切换到类型2LBT
信道接入。
终止(terminate)所述第一信道接入进程。例如,第一终端终止第一信道接入进程,切换到第二信道接入进程。
通过本申请实施例提供的技术方案,第一终端在执行用于进行与第二终端之间的SL传输的第一类型的第一信道接入进程的过程中,获取旁链路资源信息,根据该旁链路资源信息,保持第一信道接入、切换到第二类型的第二信道接入进程或终止所述第一信道接入进程,从而可以解决在旁链路传输中UE如何处理进行中的信道接入进程的问题。
在本申请实施例的一个可能的实现方式中,所述SL资源信息可以用于指示SL传输的SL资源。例如,SL资源信息可以为基站发送的动态授权或配置授权,或者,SL资源信息可以为第一终端创建选定副链路授权(Selected sidelink Grant,SG),获取所述SL资源信息,或者,SL资源信息还可以是第三终端发送的COT共享信息,即SL资源信息用于指示第三终端共享的COT的第一时频资源。下面分别针对这几种情况进行说明。
在一个可能的实现方式中,所述第一终端获取所述SL资源信息可以包括:所述第一终端接收基站发送的动态授权或配置授权,所述动态授权或配置授权指示所述SL资源。也就是说,所述SL资源信息包括来自基站的新的旁链路授权(SL grant),其中,该SL授权可以动态授权(dynamic grant,DG)或配置授权(configured grant,CG)。
其中,旁链路终端(SL UE)包括两种资源分配方式,模式1(mode1)和模式2(mode2)。其中mode1是基站调度资源,mode2是UE自己决定使用什么资源进行传输。SL资源信息可能来自基站的广播消息或者预配置的信息。UE如果工作在基站范围内并且与基站有无线资源控制(Radio Resource Control,RRC)连接,可以是mode1和/或mode2;UE如果工作在基站范围内,但与基站没有RRC连接,只能工作在mode2。如果UE在基站范围外,那么只能工作在mode2,且根据预配置的信息来进行SL传输。
对于mode 2,具体的工作方式如下:1)发送(transmit,TX)UE在资源选择被触发后,首先确定资源选择窗口,资源选择窗口的下边界在资源选择触发后的T1时间,资源选择的上边界在触发后的T2时间,其中T2是UE实现的方式在其传输块(Transport Block,TB)传输的包延时预算(packet delay budget,PDB)内选择的值,T2不早于T1。2)UE在资源选择之前,需要确定资源选择的候选资源结合(candidate resource set),根据资源选择窗口内的资源上测量的参考信号接收功率(Reference Signal Received Power,RSRP)与相应的RSRP阈值(threshold)做对比,如果RSRP低于RSRP threhold,那么该资源可以纳入候选资源集合。3)资源集合确定后,UE随机在候选资源集合中选择传输资源。另外,UE在本次传输可以为接下来的传输预留传输资源。
另外,SL UE有三种对资源的授权的方式,动态授权(DG,dynamic grant)、配置授权(CG,configured grant)及授权、选定副链路授权(selected sidelink grant,SG)。
其中,动态授权和配置授权是用于使用mode1资源分配方式的UE,动态授权的资源是由基站动态调度的,而配置授权的资源是由基站半静态调度的。配置授权分为两种类型,
即配置授权类型1(configured grant type1)和配置授权类型1(configured grant type2),前者是由RRC信令配置的,后者由RRC信令配置之后,由下行控制信息(Downlink Control Information,DCI)来激活/去激活该configured grant。
而选定副链路授权则是用于使用mode2资源分配方式的UE。UE自己选择用于传输的资源,并把这些资源作为选定副链路授权。
因此,在一个可能的实现方式中,可以是mode1UE在执行正在进行的type1LBT(ongoing type1LBT)进程,接收到来自基站的新的SL授权,UE需要处理来自基站的新的SL grant,判断保持还是终止ongoing type1LBT进程。
在一个可能的实现方式中,所述第一终端获取所述SL资源信息可以包括:所述第一终端创建选定副链路授权,所述选定副链路授权指示所述SL资源。例如,mode2UE创建一个新的SL授权,则UE需要处理自己创建的新的SL grant,判断维持还是终止ongoing type1LBT进程。
在一个可能的实现方式中,在UE接收来自基站的新的SL授权以及UE创建的选定副链路授权的情况下,例如,当UE收到基站(通过DCI)指示一个SL grant(如DG、CG),或当UE创建了新的SL grant(如selected sidelink grant,SG),该SL grant调度用type1LBT或type2LBT接入的SL传输,并且在SL传输的位置前有一个进行中的type1信道接入进程,则S220可以包括以下至少之一:
(1)在第一CAPC值大于等于第二CAPC值的情况下,所述第一终端通过所述第一信道接入进程传输所述SL资源对应的第一SL传输信息;也就是说,在第一CAPC值大于等于第二CAPC值的情况下,第一终端保持第一信道接入进程,通过第一信道接入进程传输所述SL资源信息指示的SL资源对应的第一SL传输信息,例如,接收到来自基站的新的SL授权用于调度某SL资源传输第一SL传输信息,则在第一CAPC值大于等于第二CAPC值的情况下,第一终端通过第一信道接入进程传输第一SL传输信息。
(2)在所述第一CAPC值小于第二CAPC值的情况下,所述第一终端终止所述第一信道接入进程;
(3)所述第一终端通过所述第一信道接入进程传输所述SL资源对应的第二SL传输信息;例如,第一终端保持所述第一信道接入进程,并通过所述第一信道接入进程传输所述SL资源对应的第二SL传输信息。
(4)在所述第一信道接入进程用于发送物理副链路反馈信道(Physical SideLink Feedback Channel,PSFCH)且所述第二CAPC值大于或等于第一阈值的情况下,所述第一终端保持所述第一信道接入进程;例如,CAPC值包括1~4,则第一阈值可以为1~4中的任一个正整数,具体值可以根据实际应用确定。
(5)在所述第一信道接入进程用于发送PSFCH,且所述第二CAPC值小于或等于第二阈值的情况下,所述第一终端终止所述第一信道接入进程;例如,CAPC值包括1~4,则第二阈值可以为1~4中的任一个正整数,具体值可以根据实际应用确定。在本申请实施
例中,第一阈值与第二阈值可以相同,也可以不同,具体本申请实施例不作限定。
在上述可能的实现方式中,所述第一CAPC值为所述第一信道接入进程所用的CAPC值,所述第二CAPC值为所述SL资源信息指示的CAPC值。
在上述各个可能的实现方式中,可选地,所述第一SL传输信息或第二SL传输信息包含以下至少之一:
·物理副链路共享信道(Physical SideLink Shared Channel,PSSCH);
·物理副链路控制信道(Physical SideLink Control Channel,PSCCH);
·物理副链路广播信道(Physical SideLink Broadcast Channel,PSBCH);
·PSFCH;
·副链路同步信号块(SideLink Synchronization Signal Block,S-SSB)。
在一个可能的实现方式中,在S210中,第一终端获取所述SL资源信息可以包括:所述第一终端接收第三终端发送的所述SL资源信息,其中,所述SL资源信息用于指示所述第三终端共享的信道占用时间的第一时频资源,所述第三终端包括所述第二终端或除所述第二终端之外的终端。在该可能的实现方式中,第三终端可以通过SL资源信息向第一终端指示共享COT的第一时频资源,在该可能的实现方式中,所述SL资源信息可以称之为COT共享信息(COT sharing information),该COT共享信息指示SL授权(即SL资源)。
在本申请实施例中,向其它终端共享(sharing)COT的终端可以称之为COT共享UE(COT-sharing UE,例如,上述的第三终端),该UE在一段SL-U COT sharing关系中,指示对端UE或其它UE可以使用自己共享出去的COT。在此,COT-sharing UE可能是initiator UE,也可能不是。COT-sharing UE不等价于initiator UE有两方面的原因:1.initiator UE抢占了信道之后获得一段COT,但并不一定要做COT sharing;2.不排除COT-sharing UE不是initiator UE的可能,例如,UE1为initiator UE,向UE2share COT。UE2使用了这段COT之后,还可能向UE3share COT。
而接收其它终端共享COT的终端可以称之为COT被共享UE(COT-shared UE),即在一段未授权频段的边链路(sidelink on Unlicensed band,SL-U)COT sharing关系中,接收到COT-sharing UE发送的COT sharing information的UE,所述COT共享信息指示COT-shared UE可以根据COT共享信息中的COT sharing信息,使用一段被共享出来的COT。
需说明的是,COT-shared UE这一概念在一些场景中,只是指代收到COT sharing information的UE,并不等同于“使用shared COT的UE”;而在另一些场景中,COT-shared UE则指代“使用shared COT的UE”,此时COT-shared UE也可称为响应(response)UE。COT-share UE具体指代的含义需根据各实施例结合理解。
在一个可能的实现方式中,在第一终端从第三终端接收到指示所述第三终端共享的信道占用时间COT的第一时频资源的情况下,在S220中,基于所述SL资源信息,所述第
一终端执行目标操作,包括:所述第一终端获取所述SL资源信息指示的第一时频资源,在所述第一时频资源中的一个或多个时频位置上从所述第一信道接入进程切换到所述第二信道接入进程。
例如,当COT shared UE收到COT sharing information指示的SL grant(如COT sharing grant),确定COT sharing UE发起的CO里的剩下的(remaining)CO的时频位置,则UE可以在这些位置上从type1信道接入进程切换到type 2或type 2A信道接入进程。
可选地,所述SL资源信息还用于指示以下至少之一:
(1)所述第三终端的设备类型,其中,所述设备类型包括:模式1终端或模式2终端;其中,模式1(mode 1)终端是指该终端的资源由基站或其它终端设备的,模式2(mode2)终端是指该终端的资源是由该终端自己决定的;
(2)资源类型,所述资源类型包括:模式1(mode 1)资源或模式2(mode 2)资源;其中,该资源类型可以指示共享的COT对应的资源类型,也可以是指示第三终端使用的资源类型。例如,mode 1资源是指共享的COT的资源是由基站调度的资源或其它终端调度的资源,mode 2资源是指共享的COT的资源是由第三终端选择的资源。
(3)授权类型,所述授权类型包括以下之一:动态授权、配置授权、选定副链路授权。其中,该授权类型可以指示共享的COT对应的资源类型,也可以是指示第三终端使用的授权类型。
可选的,在所述SL资源信息调度的SL传输是在所述共享的COT对应的第一时频资源上的PSSCH和/或PSCCH传输,且满足以下至少之一的情况下,所述第一终端能够将所述共享的COT对应的第一时频资源认为是(assume)任意优先级:
所述授权类型为动态授权;
所述授权类型为配置授权;
所述资源类型为模式1资源;
所述第二终端的设备类型为模式1终端;
所述第一终端的设备类型为模式1终端。
例如,如果shared COT的授权类型为CG或DG,或shared COT的资源类型为mode1资源,或UE的COT sharing UE的UE类型为mode1UE,且SL传输是在shared COT指示的资源上的PSSCH和/或PSCCH传输,则UE可以假设(assume)该shared COT为任意的优先级类型。
在上述可能的实现方式中,可选的,所述第三终端为模式1终端或模式2终端。例如,COT sharing UE为mode1UE或mode2UE。
可选的,所述第一终端为模式1终端或模式2终端。例如,COT shared UE为mode1UE或mode2UE。
可选的,所述第一终端接收所述第三终端发送的所述SL资源信息,包括:所述第一终端在模式1终端或模式2终端专用的资源上接收所述SL资源信息。例如,COT shared UE
在mode1UE或mode2UE专用的资源上接收COT sharing information。
在上述可能的实现方式中,可选的,在接收到第三终端发送的所述SL资源信息后,第一终端可以对所述SL资源信息指示的第一时频资源进行重评估(re-evaluation)或优先权抢占(pre-emption)检查。
可选的,在使用所述SL资源信息指示的第一时频资源前,所述第一终端评估该第一时频资源可用。也就是说道,第一终端对第一时频资源进行重评估或优先权抢占检查后,确定所述第一时频资源没有被其它终端抢占或预留。
在本申请实施例中,还可以根据指示第三终端共享的COT的第一时频资源的SL资源信息指示的CAPC值与第一信道接入进程所使用的CAPC值,确定对第一信道接入进程的处理方式。其中,SL资源信息指示的CAPC值可以是第三终端在抢占信道之前,确定的CAPC值,第三终端可以通过该CAPC值抢占信道获取所述共享的COT。
因此,在一个可能的实现方式中,S220中,基于所述SL资源信息,所述第一终端执行目标操作可以包括:在第二CAPC值大于或等于第一CAPC值,且所述SL资源信息所指示的所述第一时频资源满足所述第一信道接入进程的传输需求(也就是说,第一时频资源足够传输第一信道接入进程关联的所有TB)的情况下,所述第一终端执行以下至少之一:
(1)终止所述第一信道接入进程;
(2)在所述SL资源信息指示的所述第一时频资源的时频位置,从所述第一信道接入进程切换到所述第二信道接入进程;
(3)使用所述共享的COT发送所述第一信道接入进程关联的TB;在该可能的实现方式中,第一终端可以终止第一信道接入进程,使用所述共享的COT发送所述第一信道接入进程关联的所有TB。
其中,所述第二CAPC值为所述SL资源信息所指示的CAPC值,所述第一CAPC值为所述第一信道接入进程所用的CAPC值。
通过上述可能的实现方式,第一CAPC值大于或等于第一CAPC值,则第三终端抢占信道的最大可占据的COT长度大于或等于第一信道接入进程抢占的最大可占据的COT长度,而共享的COT对应的第一时频资源又满足第二信道接入进程的传输需求,则可以终端第一信道接入进程,使用共享的COT,以节约资源。
在上述可能的实现方式,可选的,所述SL资源信息指示的所第一述时频资源的时域位置不晚于所述第一信道关联的TB的传输位置。
例如,UE有一个进行中的type1信道接入进程。UE收到COT sharing information指示的SL grant(如COT sharing grant),确定COT sharing information指示资源的时频位置。若COT sharing information指示的CAPC大于或等于进行中的type1信道接入进程所用的CAPC,且COT sharing information指示的资源可以满足进行中的type1信道接入进程,或可以满足进行中的type1信道接入进程关联的所有TB(可以是1个或者多个TB),则
UE执行以下至少之一:
·UE停止进行中的type1信道接入进程;
·UE在COT sharing information指示资源的时频位置从type1信道接入进程切换到type 2或type 2A信道接入进程;
·UE使用该shared COT发送所述进行中的type1信道接入进程关联的1个或者多个TB;
可选的,所述资源的时域位置不晚于进行中的type1信道接入进程所关联的SL传输位置。
可选的,COT shared UE评估COT sharing information指示的资源可用,或COT sharing grant为有效的SL grant。
在上述可能的实现方式中,可选的所述SL资源信息所指示的所述第一时频资源满足所述第一信道接入进程的传输需求,包括以下至少之一:
(1)在所述第一终端有需要给所述第三终端发送的第一数据的情况下,所述第一时频资源中除去第二时频资源剩下的时频资源满足所述第一信道接入进程的传输需求,所述第二时频资源为发送所述第一数据使用的时频资源,其中,所述第三终端为除所述第二终端之外的终端;例如,UE1有给UE2的至少一个TB待发(进行中的信道接入进程关联的TB),接收到UE3的COT share信息,此时,如果UE1需要给UE3发数据的情况下,UE1使用UE3共享的COT资源给UE3发数据,若发完了共享的COT资源还有剩余,则UE1可以用剩下的COT发送给UE2的待发送数据。也就是说,在该可能的实现方式中,UE1使用UE3共享的COT,给UE2发送进行中的信道接入进程关联的数据。
(2)在所述第一终端需要给所述第二终端发送除了第一信道接入进程关联的TB以外的第二数据的情况下,所述第一时频资源中除去第三时频资源剩下的时频资源满足所述第一信道接入进程的传输需求,所述第三时频资源为发送所述第二数据使用的时频资源,其中,所述第二数据的优先级高于或等于所述第一信道接入进程关联的TB的优先级。也就是说,在该可能的实现方式中,第一终端使用第二终端共享的COT给第二终端发送进行中的信道接入进程关联的数据以及除该进行中的信道接入进程关联的数据之外的数据。例如,UE1有给UE2的至少一个TB(与进行中的信道接入进程关联)待发,接收到UE2的COT share信息,而UE1除了有与进行中的信道接入进程关联的数据需要发送给UE2,还有第二数据需要向UE2发送,则UE1使用UE2共享的COT资源给UE2发第二数据,若发完了共享的COT资源还有剩余,则UE1可以用剩下的COT发送给UE2进行中的信道接入进程关联的数据。
其中,上述的优先级可以是CAPC,也可以是层1优先级(L1priority,也可以称为物理层优先级),或者,还可以是逻辑信道优先级。
例如,UE有一个进行中的type1信道接入进程。UE收到COT sharing information指示的SL grant(如COT sharing grant),确定COT sharing information指示资源的时频位置。
若UE有需要给COT sharing UE发送的数据,且COT sharing information指示的CAPC大于或等于进行中的type1信道接入进程所用的CAPC,且COT sharing information指示的资源中除去给COT sharing UE发送的数据所剩下的资源可以满足进行中的type1信道接入进程,或可以满足进行中的type1信道接入进程关联的所有TB(可能为1个或者多个TB),则UE执行以下至少之一:
·UE停止进行中的type1信道接入进程;
·UE在COT sharing information指示资源的时频位置从type1信道接入进程切换到type 2或type 2A信道接入进程;
·UE使用该shared COT发送所述进行中的type1信道接入进程关联的1个或者多个TB;
可选的,所述资源的时域位置不晚于进行中的type1信道接入进程所关联的SL传输位置。
可选的,COT shared UE评估COT sharing information指示的资源可用,或COT sharing grant为有效的SL grant。
在另一个可能的实现方式中,第一终端可以使用第三终端共享的COT,但不使用其发送第一信道接入进程关联的数据,例如,第一终端的缓存中有发送给第二终端的比第一信道接入进程关联的数据更高优先级的数据,则第一终端可以从缓存中取该优先级更高的数据发给第二终端。又例如,共享的COT是由第三终端共享的,第一终端需要给第三终端发送数据,此时,第一终端不发送给UE2的TB。因此,在该可能的实现方式中,第一终端在接收第三终端发送的SL资源信息后,在S220中,基于所述SL资源信息,所述第一终端执行目标操作,包括:在所述SL资源信息指示的所述第一时频资源的时频位置与所述第一信道接入进程关联的SL传输的时频位置有部分重叠或全部重叠、所述第一终端使用所述第一时频资源,但不使用所述第一时频资源发送所述第一信道接入进程关联的至少一个TB的情况下,所述第一终端执行以下至少之一:
(1)终止所述第一信道接入进程;
(2)在所述SL资源信息指示的所述第一时频资源的时频位置,从所述第一信道接入进程切换到所述第二信道接入进程;例如,UE可以在COT sharing information指示资源的时频位置从type1信道接入进程切换到type 2或type 2A信道接入进程。
(3)为所述第一信道接入进程关联的至少一个TB执行资源重选;例如,UE为进行中的type1信道接入进程关联的1个或者多个TB执行资源重选,重新选择进行中的type1信道接入进程关联的1个或者多个TB的资源。
(4)将所述第一信道接入进程关联的至少一个反馈进程挂起;例如,UE将进行中的type1信道接入进程关联的1个或者多个混合自动重传请求(Hybrid automatic repeat request,HARQ)进程(process)挂起。
(5)触发所述第一信道接入进程关联的传输资源进行重评估或优先权抢占检查。通
过重评估或优先权抢占检查,判决第一信道接入进程关联的传输资源是否可用。
在上述可能的实现方式中,可选的,所述第一终端缓存有给所述第三终端的待发送数据,也就是说,第一终端的缓存中有给第三终端的待发送数据。或者,所述第一终端需要向所述第三终端回复PSFCH数据,即第一终端需要向第三终端回复反馈信息。
可选的,第一优先级高于或等于第二优先级,所述第一优先级为缓存的所述待发送数据中的最高逻辑信道优先级,所述第二优先级为所述第一信道接入进程关联的至少一个TB中的最高逻辑信道优先级。
例如,UE的缓存中数据的最高优先级逻辑信道的优先级高于进行中的type1信道接入进程关联的1个或者多个TB中最高优先级逻辑信道的优先级,或该数据的逻辑信道关联的CAPC优先级高于进行中的type1信道接入进程所使用的CAPC优先级。
可选的,所述第一终端使用所述第一时频资源发送目标优先级最高的以下之一:媒体接入控制层(Medium Access Control,MAC)控制单元(Control Element,CE);逻辑信道;物理信道;物理信号;其中,所述目标优先级包括以下之一:层1优先级、逻辑信道优先级(logical channel priority)、CAPC对应的优先级。例如,UE使用所述COT sharing information指示资源发送任意L1priority或logical channel priority或CAPC对应的优先级为最高优先级的MAC CE或逻辑信道或物理信道或物理信号,如PSFCH/S-SSB,又如与sidelink相关的MAC CE。
可选地,在第一终端接收所述第三终端发送的所述SL资源信息之后,所述方法还可以包括:所述第一终端评估所述SL资源信息指示的所述时频资源可用,或者,评估所述SL资源信息指示的所述时频资源有效。例如,COT shared UE收到COT sharing information,对COT sharing information指示的资源进行重评估或优先权抢占检查。COT shared UE评估COT sharing information指示的资源可用,可选的,可以理解为COT shared UE对COT sharing information指示的资源进行重评估或优先权抢占检查后,判断COT sharing information指示的资源没有被其它UE抢占或预留。
在一个可能的实现方式中,第一终端也可以使用共享的COT发送第一信道接入进程关联的部分TB,第一终端有给第二终端的多个TB待发,第一终端收到任意一个终端(可以是第二终端,也可以是第二终端之外的终端)发送的COT share信息,使用该COT资源发多个TB中的一部分。例如,共享的COT虽然不能满足第一信道接入进程的需要,例如,不够传输第一信道接入进程关联的所有TB,但可以传输第一信道接入进程关联的部分TB,则第一终端可以使用共享的COT发送第一信道接入进程关联的部分TB,当然,并不限于此,在其它情况下,第一终端也可以使用共享的COT发送第一信道接入进程关联的部分TB,具体本申请实施例中不作限定。例如,UE有一个进行中的type1信道接入进程,其关联了M个TB或者N个process的传输。UE收到COT sharing information指示的SL grant(如COT sharing grant),确定COT sharing information指示资源的时频位置,UE可以使用COT sharing information指示的资源传输进行中的type1信道接入进程关联的
部分TB或部分进程。因此,在该可能的实现方式中,在接收第三终端发送的SL资源信息的情况下,在S220中,基于所述SL资源信息,所述第一终端执行目标操作可以包括:在第一情况下,所述第一终端执行以下至少之一:
(1)所述第一终端使用所述SL资源信息指示的第一时频资源,发送所述第一信道接入进程关联的m个TB或n个进程,m和n为大于0的整数;例如,UE使用COT sharing information指示的资源发送所述资源能满足的m个TB或n个进程。
(2)所述第一终端对所述第一信道接入进程关联的p个TB进行资源重选,所述p个TB为所述第一信道接入进程关联的至少一个TB中除所述m个TB之外的TB,p为大于0的整数;例如,UE对p个TB进行资源重选,P=M-m;所述P个TB是不使用该COT sharing information指示的资源发送的TB。
(3)所述第一终端将所述第一信道接入进程关联的q个进程挂起,所述q个TB为所述第一信道接入进程关联的至少一个进程中除所述n个进程之外的进程,q为大于0的整数;例如,UE将q个process挂起,q=N-n;所述q个process是不使用该COT sharing information指示的资源发送的process。
其中,m小于M,n小于N,M为所述第一信道接入进程关联的TB的数量,N为所述第一信道接入进程关联的进程的数量。
例如,第一终端在第一信道接入进程前收到第三终端共享的COT,该共享的COT的第一时频资源与第一信道接入进程关联的资源没有重叠,则第一终端可以在共享的COT的第一时频资源的时域位置前从type1转到type2发送第一信道接入进程关联的部分TB,此时第一信道接入进程可能是一种挂起的状态。UE使用共享的COT发送所述部分TB之后恢复挂起的第一信道接入进程。
又例如,第一终端在第一信道接入进程前收到第三终端共享的COT,该共享的COT的第一时频资源与第一信道接入进程关联的资源有重叠的情况下,如果使用该共享的COT传输第一信道接入进程关联的部分TB,则第一终端终止第一信道接入进程。
在上述可能的实现方式中,可选的,所述m个TB不大于所述第一时频资源能够传输的TB数量。
可选的,所述m个TB中的任一个TB的CAPC值不大于所述SL资源信息指示的CAPC值。
可选的,所述n个进程中的任一个进程的CAPC值不大于所述SL资源信息指示的CAPC值。
可选的,所述第一情况包括以下至少之一:
(1)所述第一信道接入进程关联的M个TB中任一个TB的CAPC值不大于所述SL资源信息指示的CAPC值;例如,M个TB中任意一个TB的CAPC值不大于COT sharing information指示的CAPC值;
(2)所述第一信道接入进程关联的M个TB中至少一个TB的CAPC值不大于所述
SL资源信息指示的CAPC值;例如,M个TB中存在至少一个TB的CAPC值不大于COT sharing information指示的CAPC值。
(3)所述第一信道接入进程关联的N个进程中任一个进程的CAPC值不大于所述SL资源信息指示的CAPC值;例如,N个process中任意一个process的CAPC值不大于COT sharing information指示的CAPC值。
(4)所述第一信道接入进程关联的N个进程中至少一个进程的CAPC值不大于所述SL资源信息指示的CAPC值;例如,N个process中存在至少一个process的CAPC值不大于COT sharing information指示的CAPC值。
(5)所述SL资源信息指示的所述第一时频资源的时域位置不晚于所述第一信道接入进程关联的SL传输的位置。例如,COT sharing information指示资源的时域位置不晚于进行中的type1信道接入进程所关联的SL传输位置。
通过上述可能的实现方式,可以充分利用第三终端共享的COT,实现资源的有效利用,提高资源的利用率。
在一个可能的实现方式中,在某些情况下,第一终端可能需要保持第一信道接入进程,以保证第一终端与第二终端之间的SL传输顺利进行。因此,在一个可能的实现方式中,在接收到第三终端发送的SL资源信息的情况下,在S220中,基于所述SL资源信息,所述第一终端执行目标操作可以包括:在第二情况下,所述终端保持所述第一信道接入进程;
其中,所述第二情况包括以下至少之一:
所述第一终端评估所述第一时频资源不可用;
所述SL资源信息指示的CAPC值小于或等于所述第一信道接入进程所用的CAPC值;
所述第一时频资源不能满足所述第一信道接入进程关联的SL传输;
所述第一时频资源不能满足所述第一信道接入进程关联的至少一个TB的传输需求;
所述第一时频资源的时域位置晚于所述第一信道接入进程关联的SL的传输位置。
例如,UE有一个进行中的type1信道接入进程。UE收到COT sharing information指示的SL grant(如COT sharing grant),确定COT sharing information指示资源的时频位置。若满足以下至少之一的条件,UE保持进行中的type1信道接入进程:
·UE评估该COT sharing information指示的资源不可用;
·COT sharing information指示的CAPC值小于或等于进行中的type1信道接入进程所用的CAPC值;
·COT sharing information指示的资源不能满足进行中的type1信道接入进程,或不能满足进行中的type1信道接入进程关联的1个或者多个TB;
·COT sharing information指示资源的时域位置晚于进行中的type1信道接入进程所关联的SL传输位置。
在一个可能的实现方式中,所述SL资源信息还可能是第二终端发送的终端间协作(Inter-UE Coordination,IUC)消息中携带的用于指示所述第二终端不推荐的资源集信息。
该资源集信息所指示的资源可能与第一信道接入进程关联的资源有重叠,在这种情况下,第一终端也需要对第一信道接入进程进行处理。例如,UE有一个进行中的type1信道接入进程,UE收到一个对端UE发送的IUC消息,若IUC消息指示的non-preferred resource set资源与进行中的type1信道接入进程关联的资源有重叠,则UE需要对进行中的type1信道接入进程进行处理。
在上述可能的实现方式中,S220中,基于所述SL资源信息,所述第一终端执行目标操作可以包括:在所述不推荐的资源集信息对应的资源集中资源与所述第一信道接入进程关联的资源有重叠的情况下,所述第一终端执行以下至少之一:
终止所述第一信道接入进程;
为所述第一信道接入进程关联的至少一个TB执行资源重选;
将所述第一信道接入进程关联的至少一个反馈进程挂起;
触发对所述第一信道接入进程关联的传输资源进行重评估或优先权抢占检查;
在不推荐的所述资源集中资源的位置对先听后说LBT或净信道评估CCA执行目标动作,所述目标动作包括以下之一:不执行、停止、终止、暂停;
在不推荐的所述资源集中资源的位置保持LBT所用的计数器的数值不变,所述计数器为基于感知时隙内的信道感知调整的计数器。
例如,UE有一个进行中的type1信道接入进程。UE收到一个对端UE发送的IUC消息。若IUC消息指示的non-preferred resource set资源与进行中的type1信道接入进程关联的资源有重叠,则UE执行以下至少之一:
·UE停止进行中的type1信道接入进程;
·UE为进行中的type1信道接入进程关联的1个或者多个TB执行资源重选;
·UE将进行中的type1信道接入进程关联的1个或者多个HARQ process挂起;
·UE触发进行中的type1信道接入进程关联的传输资源重评估或优先权抢占检查;
·UE在non-preferred resource set资源的位置对LBT或CCA(Clear Channel Assessment,净信道评估)执行目标动作,所述目标动作为“不执行、停止、终止”或“暂停”;
·UE在non-preferred resource set资源的位置保持LBT所用的计数器N数值不变,所述计数器N为基于感知时隙(sensing slot)内的信道感知调整的计数器。
通过上述可能的实现方式,可以在IUC消息指示的non-preferred resource set资源与进行中的type1信道接入进程关联的资源有重叠时,进行相应的处理,以保证SL传输的可靠性。
