为便于理解本申请实施例的技术方案，以下通过具体实施例详述本申请的技术方案。以下相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合，其均属于本申请实施例的保护范围。本申请实施例包括以下内容中的至少部分内容。
图1是本申请实施例适用的一种通信系统的示意图。车载终端(车载终端121和车载终端122)的传输资源是由基站110分配的，车载终端根据基站110分配的资源在侧行链路上进行数据的发送。具体地，基站110可以为终端分配单次传输的资源，也可以为终端分配半静态传输的资源。
图2是本申请实施例适用的另一种通信系统的示意图。车载终端(车载终端131和车载终端132)在侧行链路的资源上自主选取传输资源进行数据传输。可选地，车载终端可以随机选取传输资源，或者通过侦听的方式选取传输资源。
需要说明的是，在侧行通信中，根据进行通信的终端所处的网络覆盖情况，可以分为网络覆盖内侧行通信，如图3所示；部分网络覆盖侧行通信，如图4所示；及网络覆盖外侧行通信，如图5所示。
图3：在网络覆盖内侧行通信中，所有进行侧行通信的终端均处于基站的覆盖范围内，从而，上述终端均可以通过接收基站的配置信令，基于相同的侧行配置进行侧行通信。
图4：在部分网络覆盖侧行通信情况下，部分进行侧行通信的终端位于基站的覆盖范围内，这部分终端能够接收到基站的配置信令，而且根据基站的配置进行侧行通信。而位于网络覆盖范围外的终端，无法接收基站的配置信令，在这种情况下，网络覆盖范围外的终端将根据预配置(pre-configuration) 信息及位于网络覆盖范围内的终端发送的物理侧行广播信道(Physical Sidelink Broadcast Channel，PSBCH)中携带的信息确定侧行配置，进行侧行通信。
图5：对于网络覆盖外侧行通信，所有进行侧行通信的终端均位于网络覆盖范围外，所有终端均根据预配置(pre-configuration)信息确定侧行配置进行侧行通信。
图6：对于有中央控制节点的侧行通信，多个终端构成一个通信组，该通信组内具有中央控制节点，又可以称为组头终端(Cluster Header，CH)，该中央控制节点具有以下功能之一：负责通信组的建立；组成员的加入、离开；进行资源协调，为其他终端分配侧行传输资源，接收其他终端的侧行反馈信息；与其他通信组进行资源协调等功能。
需要说明的是，设备到设备通信是基于终端到终端(Device to Device，D2D)的一种侧行链路(Sidelink，SL)传输技术，与传统的蜂窝系统中通信数据通过基站接收或者发送的方式不同，车联网系统采用终端到终端直接通信的方式，因此具有更高的频谱效率以及更低的传输时延。在3GPP定义了两种传输模式，分别记为：第一模式(sidelink resource allocation mode 1)和第二模式(sidelink resource allocation mode 2)。
第一模式：终端的传输资源是由基站分配的，终端根据基站分配的资源在侧行链路上进行数据的发送；基站可以为终端分配单次传输的资源，也可以为终端分配半静态传输的资源。如图3所示，终端位于网络覆盖范围内，网络为终端分配侧行传输使用的传输资源。
第二模式：终端在资源池中选取一个资源进行数据的传输。如图5所示，终端位于小区覆盖范围外，终端在预配置的资源池中自主选取传输资源进行侧行传输；或者，如图3所示，终端在网络配置的资源池中自主选取传输资源进行侧行传输。
在新无线-车辆到其他设备(New Radio-Vehicle to Everything，NR-V2X)中，支持自动驾驶，因此对车辆之间数据交互提出了更高的要求，如更高的吞吐量、更低的时延、更高的可靠性、更大的覆盖范围、更灵活的资源分配等。
在LTE-V2X中，支持广播传输方式，在NR-V2X中，引入了单播和组播的传输方式。对于单播传输，其接收端终端只有一个终端，如图7所示，UE1、UE2之间进行单播传输；对于组播传输，其接收端是一个通信组内的所有终端，或者是在一定传输距离内的所有终端，如图8所示，UE1、UE2、UE3和UE4构成一个通信组，其中UE1发送数据，该组内的其他终端设备都是接收端终端；对于广播传输方式，其接收端是发送端终端周围的任意一个终端，如图9所示，UE1是发送端终端，其周围的其他终端，UE2-UE6都是接收端终端。
为便于更好的理解本申请实施例，对本申请相关的NR-V2X系统帧结构进行说明。
NR-V2X中的时隙结构图10所示，图10中的(a)表示时隙中不包括物理侧行反馈信道(Physical Sidelink Feedback Channel，PSFCH)的时隙结构；图10中的图(b)表示包括PSFCH的时隙结构。
NR-V2X中物理侧行控制信道(Physical Sidelink Control Channel，PSCCH)在时域上从该时隙的第二个侧行符号开始，占用2个或3个正交频分复用(Orthogonal frequency-division multiplexing，OFDM)符号，在频域上可以占用{10,12 15,20,25}个物理资源块(physical resource block，PRB)。为了降低UE对PSCCH的盲检测的复杂度，在一个资源池内只允许配置一个PSCCH符号个数和PRB个数。另外，因为子信道为NR-V2X中物理侧行共享信道(Physical Sidelink Shared Channel，PSSCH)资源分配的最小粒度，PSCCH占用的PRB个数必须小于或等于资源池内一个子信道中包含的PRB个数，以免对PSSCH资源选择或分配造成额外的限制。PSSCH在时域上也是从该时隙的第二个侧行符号开始，该时隙中的最后一个时域符号为保护间隔(Guard Period，GP)符号，其余符号映射PSSCH。该时隙中的第一个侧行符号是第二个侧行符号的重复，通常接收端终端将第一个侧行符号用作自动增益控制(Auto gain control，AGC)符号，该符号上的数据通常不用于数据解调。PSSCH在频域上占据M个子信道，每个子信道包括N个连续的PRB。如图10中的(a)所示。
当时隙中包含PSFCH信道时，该时隙中倒数第二个符号和倒数第三个符号用作PSFCH信道传输，并且倒数第三个符号上的数据是倒数第二个符号上数据的重复，在PSFCH信道之前的一个时域符号用作GP符号，如图10中的(b)所示。
为便于更好的理解本申请实施例，对本申请相关的非授权频谱进行说明。
非授权频谱是国家和地区划分的可用于无线电设备通信的频谱，该频谱通常被认为是共享频谱，即不同通信系统中的通信设备只要满足国家或地区在该频谱上设置的要求，就可以使用该频谱，不需要向政府申请专有的频谱授权。
为了让使用非授权频谱进行无线通信的各个通信系统在该频谱上能够友好共存，一些国家或地区规定了使用非授权频谱必须满足的要求。例如，通信设备遵循“LBT”原则，即通信设备在非授权频谱的信道上进行信号发送前，需要先进行信道侦听，只有当信道侦听结果为信道空闲时，该通信设备 才能进行信号发送；如果通信设备在非授权频谱的信道上的信道侦听结果为信道忙，该通信设备不能进行信号发送。为了保证公平性，在一次传输中，通信设备使用非授权频谱的信道进行信号传输的时长不能超过最大信道占用时间(Maximum Channel Occupancy Time，MCOT)。
在非授权频谱上的信号传输包括以下基本概念：
最大信道占用时间(MCOT)：指LBT成功后允许使用非授权频谱的信道进行信号传输的最大时间长度，不同信道接入优先级下有不同的MCOT。当前MCOT的最大取值为10ms。应理解，该MCOT为信号传输占用的时间。
信道占用时间(COT)：指LBT成功后使用非授权频谱的信道进行信号传输的时间长度，该时间长度内信号占用信道可以是不连续的。其中，一次COT最长不能超过20ms，并且，该COT内的信号传输占用的时间长度不超过MCOT。
网络设备(即基站)的信道占用时间(gNB-initiated COT)：也称为网络设备发起的COT，指网络设备LBT成功后获得的一次信道占用时间。网络设备的信道占用时间内除了可以用于下行传输，也可以在满足一定条件下用于UE进行上行传输。
当基站发起COT后，除了可以将该COT内的资源用于下行传输，还可以将该COT内的资源共享给终端进行上行传输。COT内的资源共享给终端进行上行传输时，终端可以使用的信道接入方式为Type2A信道接入、Type2B信道接入或Type2C信道接入，其中，Type2A信道接入、Type2B信道接入和Type2C信道接入均为基于固定长度的监听时隙的信道接入方式。
终端的信道占用时间(UE-initiated COT)：也称为终端发起的COT，指终端LBT成功后获得的一次信道占用时间。
在NR-U中，有以下几种信道接入方式：Type1的信道接入方式、Type2A信道接入、Type2B信道接入和Type2C信道接入。
Type1的信道接入方式(又称为类型1信道接入方式)：基于竞争窗口大小调整的随机回退的多时隙的信道检测，根据信道接入优先级p，可以发起长度为T mcot的信道占用，基站使用type1的信道接入方式，除了发送自己的数据，还可以将COT共享给UE，UE使用type1的信道接入方式，除了发送自己的数据，还可以将COT共享给基站。下表1给出了终端进行Type-1信道接入时的信道接入优先级及其对应的参数，p取值越小，信道接入优先级越高。
表1 不同信道优先级对应的信道接入参数
信道接入优先级(p) m p CW min,p CW max,p T mcot,p 允许的CW p取值
1 2 3 7 2ms {3,7}
2 2 7 15 4ms {7,15}
3 3 15 1023 6或10ms {15,31,63,127,255,511,1023}
4 7 15 1023 6或10ms {15,31,63,127,255,511,1023}
需要说明的是，在上述表1中，m p是指信道接入优先级p对应的回退时隙个数，CW p是指信道接入优先级p对应的竞争窗口大小，CW min,p是指信道接入优先级p对应的CW p取值的最小值，CW max,p是指信道接入优先级p对应的CW p取值的最大值，T mcot,p是指信道接入优先级p对应的信道最大占用时间长度。
NR-U中的Type1的4种信道接入优先级，p＝1为最高优先级。
Type2的信道接入方式是基于固定长度的信道监听时隙的信道接入方式。
Type2A的信道接入方式(又称为类型2A信道接入方式)，25us的信道的单时隙的检测，数据开始发送前25us开始信道检测。1个16us的检测和1个9us的检测，如果信道都是空闲，则认为信道空闲的，可以进行信道接入。
Type2B的信道接入方式(又称为类型2B信道接入方式)，固定长度为16us的单时隙的信道检测，检测在最后的9us的时间内，有4us以上空闲就认为信道是空闲的。
Type2C的信道接入方式(又称为类型2C信道接入方式)，不进行信道检测，直接传输，因为本次传输距离上一次传输之间时间差小于16us，则可以认为是同一次的传输，但传输长度不超过584us。
为便于更好的理解本申请实施例，对本申请所解决的技术问题进行说明。
当侧行传输系统工作在非授权频谱上(可称为SL-U系统)时，终端在进行侧行传输前需要通过LBT判断信道是否空闲，如果空闲可以使用信道进行侧行传输，否则不能进行侧行传输。当终端使用 Type1的信道接入方式判断信道空闲时，终端可以抢占信道进行侧行传输，并且将信道占用时间(COT)共享给其他终端，以辅助其他终端进行信道接入。若终端接收到其他终端共享的COT信息，在该COT对应的时间内可以使用Type2类型的信道接入方式，如使用Type2A、Type2B或Type2C的信道接入方式，从而提高接入信道的成功率。若终端没有接收到其他终端发送的共享COT信息，通常只能使用Type1信道接入方式。但是，在SL-U系统中，哪些终端可以使用其他终端共享的COT信息进行信道接入，或者当终端接收到多个共享的COT信息时，如何使用接收到的COT信息接入信道，上述问题是SL-U系统中需要解决的问题。
基于上述问题，本申请提出了一种侧行传输的方案，当终端设备获取N个COT共享信息时，可以从N个COT共享信息中确定目标COT共享信息，以及基于目标COT共享信息对应的参数进行信道接入，从而优化非授权频谱上的侧行传输。
以下通过具体实施例详述本申请的技术方案。
图11是根据本申请实施例的无线通信的方法200的示意性流程图，如图11所示，该无线通信的方法200可以包括如下内容中的至少部分内容：
S210，终端设备获取N个COT共享信息，N为正整数；
S220，该终端设备从该N个COT共享信息中确定目标COT共享信息；
S230，该终端设备根据该目标COT共享信息对应的参数进行信道接入。
在一些实施例中，该N个COT共享信息由其他终端提供。
例如，该N个COT共享信息分别由N个其他终端提供。
又例如，该N个COT共享信息由组头终端(也可以称之为中央控制节点)提供。其中，该N个COT共享信息由该组头终端从其所处的通信组内的N个终端处获取。
在一些实施例中，该N个COT共享信息中的一个COT共享信息由网络设备提供，以及该N个COT共享信息中的其他N-1个COT共享信息由其他终端提供。
例如，该N个COT共享信息中的其他N-1个COT共享信息分别由N-1个其他终端提供。
又例如，该N个COT共享信息中的其他N-1个COT共享信息由组头终端(也可以称之为中央控制节点)提供。其中，该N个COT共享信息中的其他N-1个COT共享信息由该组头终端从其所处的通信组内的N-1个终端处获取。
在一些实施例中，COT共享信息承载在侧行控制信息(Sidelink Control Information，SCI)或媒体接入控制控制元素(Media Access Control Control Element，MAC CE)中，其中SCI包括第一阶SCI或第二阶SCI。
在一些实施例中，该N个COT共享信息中的COT共享信息中携带以下信息中的至少一种：
资源块集合信息、COT的时长信息、COT的起始时隙位置、优先级信息、信道接入类型信息、目标标识信息。
在一些实施例中，资源块集合信息可以根据与COT共享信息一起发送的PSCCH或PSSCH的传输资源对应的资源块集合确定，即根据与COT共享信息一起发送的PSCCH或PSSCH占据的资源块集合确定该资源块集合信息。应理解，本申请中的实施例以COT共享信息中携带资源块集合信息为例进行说明，本申请的实施例同样适用于资源块集合信息是根据与COT共享信息一起发送的PSCCH或PSSCH的传输资源对应的资源块集合确定的情况。
具体例如，UE-A发送COT共享信息，在COT共享信息中包括资源块集合信息，UE-B接收到UE-A发送的COT共享信息，根据COT共享信息中携带的资源块集合信息确定是否可以利用该COT共享信息进行信道接入。
具体例如，UE-A发送COT共享信息，并且与该COT共享信息一起发送PSSCH，该PSSCH的传输资源对应N个资源块集合，N为正整数，UE-B接收到UE-A发送的COT共享信息，并且根据与该COT共享信息一起发送的PSSCH的传输资源确定其对应的N个资源块集合，UE-B根据该N个资源块集合确定是否可以利用该COT共享信息进行信道接入。
在一些实施例中，目标标识信息可以根据SCI中的目标标识信息域确定。应理解，本申请中的实施例以COT共享信息中携带目标标识信息为例进行说明，本申请的实施例同样适用于目标标识信息是根据与COT共享信息一起发送的SCI中的目标标识信息域确定的情况。
具体例如，UE-A发送COT共享信息，在COT共享信息中包括目标标识信息，UE-B接收到UE-A发送的COT共享信息，根据COT共享信息中携带的目标标识信息确定是否可以利用该COT共享信息进行信道接入。
具体例如，UE-A发送COT共享信息，并且与该COT共享信息一起发送SCI，在SCI中携带目标标识信息，UE-B接收到UE-A发送的COT共享信息，并且根据与该COT共享信息一起发送的SCI 确定目标标识信息，UE-B根据该目标标识信息确定是否可以利用该COT共享信息进行信道接入。
在一些实施例中，目标标识信息还可以包括区域标识(Zone ID)，即位于该Zone ID对应的区域内的终端可以使用该COT共享信息。在一些实施例中，该区域标识(Zone ID)承载在COT共享信息，或者，该区域标识(Zone ID)承载在与COT共享信息一起发送的SCI或MAC CE中。
具体例如，UE-A发送COT共享信息，并且与该COT共享信息一起发送SCI，在SCI中携带Zone ID信息，UE-B接收到UE-A发送的COT共享信息，并且根据与该COT共享信息一起发送的SCI确定Zone ID信息，UE-B确定是否属于该Zone ID对应的区域，进而确定是否可以利用该COT共享信息进行信道接入。例如，若终端属于该Zone ID对应的区域，则可以利用该COT共享信息进行信道接入，否则不能利用该COT共享信息进行信道接入。
具体例如，UE-A发送COT共享信息，并且在COT共享信息中携带Zone ID信息，UE-B接收到UE-A发送的COT共享信息，并且根据COT共享信息中的Zone ID信息确定是否属于该Zone ID对应的区域，进而确定是否可以利用该COT共享信息进行信道接入。例如，若终端属于该Zone ID对应的区域，则可以利用该COT共享信息进行信道接入，否则不能利用该COT共享信息进行信道接入。
在一些实施例中，第一终端发送COT共享信息时，在COT共享信息中(或与COT共享信息同时发送的SCI或MAC CE中)携带第一Zone ID信息，只有位于该第一Zone ID信息对应的区域内的终端可以使用该COT共享信息；另外，在COT共享信息中(或与COT共享信息同时发送的SCI或MAC CE中)携带第二Zone ID信息，该第二Zone ID信息用于指示第一终端所在的区域。第二终端接收到该COT共享信息时，确定是否是与第一终端所在的区域最近的并且对应于所述第一Zone ID的区域。例如，若第二终端属于该第一Zone ID对应的区域，并且是与第一终端所在的区域最近的对应于该第一Zone ID的区域，则可以利用该COT共享信息进行信道接入，否则不能利用该COT共享信息进行信道接入。

应理解，信道接入类型信息用于指示其他终端在共享COT时长内接入信道时使用的信道接入类型。
在一些实施例中，终端设备可以根据预配置信息或网络配置信息确定在共享COT时长内的信道接入类型。例如，在资源池配置信息或侧行带宽部分(Band Width Part，BWP)配置信息中包括指示信息，该指示信息指示终端在使用共享的COT进行信道接入时的信道接入类型。此时，在COT共享信息中不需要指示信道接入类型(也即，在COT共享信息中可以不携带信道接入类型信息)。
具体例如，对于N个COT共享信息中的第i个COT共享信息，第i个COT共享信息中包括的目标标识信息用于确定可以使用第i个COT共享信息的终端。例如，该目标标识信息包括终端标识信息，只有该终端标识信息对应的终端可以使用该第i个COT共享信息接入信道。又例如，该目标标识信息包括组标识信息，只有属于该组标识信息对应的组的终端可以使用该第i个COT共享信息接入信道。又例如，该目标标识信息包括业务类型信息，只有传输该业务类型信息对应的业务类型的终端可以使用该第i个COT共享信息接入信道。应理解，目标标识信息可以包括终端标识信息的部分信息、或组标识信息的部分信息、或业务类型信息的部分信息。例如，终端标识信息为24比特长，而COT共享信息中包括的目标标识信息为16比特，即包括部分终端标识信息。

在一些实施例中，当终端设备利用目标COT共享信息对应的参数进行信道接入，且在发送自己的COT共享信息时，该终端设备可以根据该目标COT共享信息确定该终端设备发送的COT共享信 息中携带的参数。
例如，该终端设备发送的COT共享信息中携带的资源块集合信息可以与目标COT共享信息中携带的资源块集合信息一致，或者，该终端设备发送的COT共享信息中携带的资源块集合信息可以基于目标COT共享信息中携带的资源块集合信息确定。

再例如，该终端设备发送的COT共享信息中携带的目标标识信息可以与目标COT共享信息中携带的目标标识信息一致，或者，该终端设备发送的COT共享信息中携带的目标标识信息可以基于目标COT共享信息中携带的目标标识信息确定。
再例如，该终端设备发送的COT共享信息中携带的COT时长可以根据该终端发送COT信息所在的时隙确定的剩余COT时长确定。
在一些实施例中，终端设备可以根据优先级信息、目标标识信息、资源块集合信息等确定是否可以利用COT共享信息进行信道接入。
在一些实施例中，上述S220具体可以包括：

在一些实施例中，该待传输侧行数据对应的信道接入优先级信息基于第一对应关系确定；
其中，该第一对应关系表示以下信息中的一种与信道接入优先级之间的对应关系：侧行优先级、侧行业务对应的时延信息、侧行业务对应的可靠性信息、侧行业务对应的服务质量(Quality of Service，QoS)信息。
具体例如，侧行业务对应的QoS信息为PC5 5G QoS标识(PC5 5G QoS Identifier，PQI)。
在一些实施例中，终端设备根据预配置信息(如资源池配置信息或侧行BWP配置信息)或网络配置信息(如资源池配置信息或侧行BWP配置信息)获取该第一对应关系。
在一些实施例中，在该第一信息至少包括该待传输侧行数据对应的优先级信息的情况下，该终端设备将该N个COT共享信息中的第一COT共享信息确定为该目标COT共享信息；其中，该待传输侧行数据对应的优先级高于或等于第一优先级信息对应的优先级，该第一优先级信息对应的优先级基于该第一COT共享信息确定。
在一些实施例中，该第一优先级信息对应的优先级包括优先级门限值或优先级取值。
在一些实施例中，N个COT共享信息中的每一个COT共享信息均对应一个第一优先级信息。对于第i个COT共享信息，在待传输侧行数据对应的优先级高于或等于第i个COT共享信息对应的第一优先级信息对应的优先级的情况下，终端设备可以使用第i个COT共享信息接入信道，否则，无法使用第i个COT共享信息接入信道。
在一些实施例中，该第一优先级信息为该终端设备基于该第一COT共享信息获取的。例如，该第一COT共享信息包括该第一优先级信息。
在一些实施例中，该第一优先级信息为该终端设备基于提供该第一COT共享信息的设备的侧行控制信息(Sidelink Control Information，SCI)中的优先级信息域确定的。例如，终端设备将提供第一COT共享信息的设备的SCI中的优先级信息域携带的优先级作为第一优先级信息。又例如，终端设备根据提供第一COT共享信息的设备的SCI中的优先级信息域确定信道接入优先级，进一步的，根据信道接入优先级确定第一优先级信息对应的优先级，如，将信道接入优先级作为第一优先级信息对应的优先级。
在一些实施例中，该第一优先级信息对应的优先级也可以基于预配置信息(如资源池配置信息或侧行BWP配置信息)或网络配置信息(如资源池配置信息或侧行BWP配置信息)确定，或者，该 第一优先级信息对应的优先级也可以从预配置信息(如资源池配置信息或侧行BWP配置信息)或网络配置信息(如资源池配置信息或侧行BWP配置信息)中获取。
在一些实施例中，该第一优先级信息对应于侧行优先级信息，或者，该第一优先级信息对应于信道接入优先级信息。
在一些实施例中，在该第一优先级信息对应于侧行优先级信息的情况下，该待传输侧行数据对应的优先级信息为该待传输侧行数据对应的侧行优先级信息。
在一些实施例中，在该第一优先级信息对应于信道接入优先级信息的情况下，该待传输侧行数据对应的优先级信息为该待传输侧行数据对应的信道接入优先级信息。

具体例如，如图12所示，UE-A在时隙n之前通过Type 1的信道接入方式接入信道，如果信道接入成功，UE-A在时隙n进行侧行传输，并且在SCI中携带COT共享信息，COT共享时长的起始位置为时隙n的下一个时隙，即时隙n+1，COT共享的剩余COT时长为4个时隙，即表示从时隙n+1开始的4个时隙，即共享的COT时长包括时隙n+1至时隙n+4。可选的，若COT共享信息中指示COT共享的起始位置为时隙n+2，COT时长为2个时隙，即表示共享的COT范围为时隙n+2开始的2个时隙，即对应于时隙n+2和时隙n+3。可选地，在COT共享信息中还包括优先级信息，若优先级信息表示侧行优先级，如该优先级信息指示优先级取值为3，即只有优先级高于或等于该优先级的其他终端才能使用该COT共享信息接入信道，如在时隙n+1至时隙n+4中使用Type2A、Type2B或Type2C的信道接入类型接入信道。如图12中所示，UE-B、UE-C、UE-D和UE-E的侧行优先级的值都高于COT共享信息中指示的优先级，则UE-B、UE-C、UE-D和UE-E在COT时长范围内使用Type2A信道接入方式接入信道。若其他终端的优先级低于COT共享信息中指示的优先级，则不能使用该COT共享信息接入信道，只能使用Type1的信道接入类型接入信道。如图13中所示，若UE-A发送的COT共享信息中包括的优先级信息的取值为3，UE-E的优先级取值为5，表示UE-E的优先级低于COT共享信息中指示的优先级(优先级的值越低表示优先等级越高)，则UE-E不能在COT时长范围内使用Type2A的信道接入类型接入信道，或者，UE-E不能使用UE-A发送的COT共享信息进行信道接入，UE-E只能通过Type1信道接入方式接入信道。可选地，若UE-A发送的COT共享信息中包括的优先级表示为信道接入优先级，如表1所示，并且p＝2，则只有当其他终端待传输的侧行数据对应的信道接入优先级高于或等于2时(即信道接入优先级等于1或2)，才能使用该COT共享信息接入信道，否则不能。
在一些实施例中，在该第一信息至少包括该终端设备的标识信息的情况下，该终端设备将该N个COT共享信息中的第二COT共享信息确定为该目标COT共享信息；其中，该第二COT共享信息包括目标标识信息或与所述第二COT共享信息同时发送的SCI中包括目标标识信息，且该目标标识信息对应的标识包括该终端设备的标识，或该目标标识信息对应的业务类型是该终端设备待传输侧行数据对应的业务类型，或该终端所在的区域属于该目标标识信息中携带的Zone ID信息对应的区域。
具体例如，第二COT共享信息中包括的目标标识信息用于确定可以使用该第二COT共享信息的终端。又例如，与所述第二COT共享信息同时发送的SCI中包括目标标识信息，该目标标识信息用于确定可以使用该第二COT共享信息的终端。
可选的，目标标识信息包括终端标识信息，只有该终端标识信息对应的终端可以使用该第二COT共享信息接入信道；或者，该目标标识信息包括组标识信息，只有属于该组标识信息对应的组的终端可以使用该第二COT共享信息接入信道；或者，该目标标识信息包括业务类型信息，只有传输该业务类型信息对应的业务类型的终端可以使用该第二COT共享信息接入信道；或者，目标标识信息包括Zone ID信息，只有位于该Zone ID信息对应的区域内的终端可以使用该第二COT共享信息接入信道。应理解，目标标识信息所包括的终端标识信息可以是终端标识信息的部分信息，或者，目标标识信息所包括的组标识信息可以是组标识信息的部分信息，或者，目标标识信息所包括的业务类型信息可以是业务类型信息的部分信息，或者，目标标识信息所包括的Zone ID信息可以是Zone ID信息的部分信息。
在一些实施例中，该目标标识信息包括允许使用该第二COT共享信息的终端标识信息；或者，
该目标标识信息包括允许使用该第二COT共享信息的终端组的标识信息；或者，该目标标识信 息包括允许使用该第二COT共享信息的终端所在的区域对应的区域标识信息。
例如，N个COT共享信息中的第i个COT共享信息中包括终端标识信息，如，该终端标识信息用于指示UE-C，则只有UE-C才可以在第i个COT共享信息对应的COT时长范围内使用Type2A、Type2B或Type2C的信道接入类型接入信道，其他终端不能在第i个COT共享信息对应的COT时长内使用Type2A、Type2B或Type2C的信道接入类型接入信道。
又例如，UE-A、UE-B、UE-C、UE-D属于第一通信组，UE-E不属于该第一通信组，在UE-A发送的COT共享信息中包括组标识信息，该组标识信息用于指示第一通信组，则该第一通信组内的终端，如UE-B、UE-C、UE-D，可以在UE-A发送的COT共享信息对应的COT时长范围内使用Type2A、Type2B或Type2C的信道接入类型接入信道，而该第一通信组之外的终端，如UE-E，不能在UE-A发送的COT共享信息对应的COT时长范围内使用Type2A、Type2B或Type2C的信道接入类型接入信道，如图13所示。
又例如，在UE-A发送的COT共享信息中包括业务类型信息，该业务类型信息用于指示业务类型A，其中，UE-B的待传输侧行数据对应的业务类型为业务类型A，UE-C的待传输侧行数据对应的业务类型为业务类型A，UE-D的待传输侧行数据对应的业务类型为业务类型A，UE-E的待传输侧行数据对应的业务类型为业务类型B，则UE-B、UE-C和UE-D可以在UE-A发送的COT共享信息对应的COT时长范围内使用Type2A、Type2B或Type2C的信道接入类型接入信道，而UE-E不能在UE-A发送的COT共享信息对应的COT时长范围内使用Type2A、Type2B或Type2C的信道接入类型接入信道，如图13所示。
在一些实施例中，在该第一信息至少包括资源块集合信息的情况下，该终端设备将该N个COT共享信息中的第三COT共享信息确定为该目标COT共享信息；其中，该第三COT共享信息包括目标资源块集合信息，且该终端设备确定使用的资源块集合属于该目标资源块集合信息对应的资源块集合；或者，与该第三COT共享信息同时发送的PSCCH或PSSCH的传输资源对应的资源块集合包括所述终端设备确定使用的资源块集合。
具体例如，COT共享信息承载在SCI或MAC CE中，当UE-A发送COT共享信息时，会同时发送PSSCH，根据该PSSCH的传输资源对应的资源块集合信息可以确定目标资源块集合。UE-A发送COT共享信息时同时发送PSSCH，因此，UE-A使用PSSCH传输资源对应的资源块集合发送PSSCH即表示UE-A在该资源块集合上LBT成功。UE-B获取UE-A发送的COT共享信息，根据与该COT共享信息同时发送的PSSCH的传输资源可以确定目标资源块集合，当该目标资源块集合信息所指示的资源块集合中包括UE-B待发送的侧行传输资源对应的资源块集合时，UE-B才能使用该COT共享信息进行信道接入。
具体例如，UE-A在COT共享信息中携带目标资源块集合信息，该目标资源块集合信息用于指示该UE-A在该目标资源块集合信息对应的资源块集合上执行LBT或信道接入成功。UE-B获取UE-A发送的COT共享信息，根据该COT共享信息中携带的目标资源块集合信息确定是否可以利用该COT共享信息进行信道接入。
在一些实施例中，当终端设备确定使用第一资源块集合进行侧行传输时，只有当终端设备获取的COT共享信息中的目标资源块集合信息所指示的资源块集合中包括该第一资源块集合时，终端设备才能使用该COT共享信息进行信道接入。
例如，资源池中包括3个资源块集合，分别对应资源块集合0、资源块集合1和资源块集合2；第一终端确定将要在资源块集合1中进行侧行传输。第一终端接收到第二终端发送的COT共享信息a，该COT共享信息a中包括的目标资源块集合信息指示资源块集合0和资源块集合1；第一终端接收到第三终端发送的COT共享信息b，该COT共享信息b中包括的目标资源块集合信息指示资源块集合0；第一终端接收到第四终端发送的COT共享信息c，该COT共享信息c中包括的目标资源块集合信息指示资源块集合1和资源块集合2；则第一终端使用第二终端发送的COT共享信息(即COT共享信息a)进行信道接入，或者，第一终端使用第四终端发送的COT共享信息(即COT共享信息c)进行信道接入，不能使用第三终端发送的COT共享信息(即COT共享信息b)进行信道接入。
又例如，资源池中包括3个资源块集合，分别对应资源块集合0、资源块集合1和资源块集合2；第一终端确定将要在资源块集合1和资源块集合2中进行侧行传输。第一终端接收到第二终端发送的COT共享信息A，该COT共享信息A中包括的目标资源块集合信息指示资源块集合0和资源块集合1；第一终端接收到第三终端发送的COT共享信息B，该COT共享信息B中包括的目标资源块集合信息指示资源块集合0；第一终端接收到第四终端发送的COT共享信息C，该COT共享信息C中包括的目标资源块集合信息指示资源块集合1和资源块集合2；则第一终端只能使用第四终端发送的COT共享信息(即COT共享信息C)进行信道接入，不能使用第二终端发送的COT共享信息(即 COT共享信息A)和第三终端发送的COT共享信息(即COT共享信息B)进行信道接入。
在一些实施例中，N个COT共享信息中的第i个COT共享信息中携带第一优先级信息、目标资源块集合信息和目标标识信息，当终端设备接收到第i个COT共享信息时，只有第i个COT共享信息中的目标标识信息包括该终端设备的标识信息，并且该终端设备的优先级高于或等于第i个COT共享信息中的第一优先级信息指示的优先级，并且第i个COT共享信息中的目标资源块集合信息指示的资源块集合包括该终端设备将要进行侧行发送所使用的资源块集合时，终端设备才能使用第i个COT共享信息对应的参数进行信道接入，如在第i个COT共享信息对应的COT时长内使用Type2A的信道接入方式进行信道接入。
在一些实施例中，N个COT共享信息中的第i个COT共享信息中携带第一优先级信息、目标资源块集合信息和目标标识信息，当终端设备接收到第i个COT共享信息时，第i个COT共享信息中的目标标识信息包括该终端设备的标识信息，或者，该终端设备的优先级高于或等于第i个COT共享信息中的第一优先级信息指示的优先级，或者，第i个COT共享信息中的目标资源块集合信息指示的资源块集合包括该终端设备将要进行侧行发送所使用的资源块集合时，终端设备才能使用第i个COT共享信息对应的参数进行信道接入，如在第i个COT共享信息对应的COT时长内使用Type2A的信道接入方式进行信道接入。
在一些实施例中，该终端设备从资源池配置信息或侧行BWP配置信息中获取第一指示信息；其中，该第一指示信息用于指示该终端设备根据该第一信息从该N个COT共享信息中确定该目标COT共享信息。也即，在获知该第一指示信息所指示的内容之后，该终端设备根据该第一信息从该N个COT共享信息中确定该目标COT共享信息。
具体例如，该第一指示信息可以是资源池配置信息或侧行BWP配置信息中的一个或多个信息元素(Information element，IE)，其中，该信息元素可以是字段或元素或域，本申请对此并不限定。
具体例如，该第一指示信息指示终端设备的待传输侧行数据对应的优先级信息，则终端设备根据待传输侧行数据对应的优先级信息从该N个COT共享信息中确定该目标COT共享信息。
具体例如，该第一指示信息指示终端设备的标识信息，则终端设备根据该终端设备的标识信息从该N个COT共享信息中确定该目标COT共享信息。
具体例如，该第一指示信息指示终端设备确定使用的资源块集合信息，则终端设备根据该终端设备确定使用的资源块集合信息从该N个COT共享信息中确定该目标COT共享信息。
具体例如，该第一指示信息指示优先级信息，则终端设备根据优先级信息从该N个COT共享信息中确定该目标COT共享信息。
具体例如，该第一指示信息指示资源块集合信息，则终端设备根据资源块集合信息从该N个COT共享信息中确定该目标COT共享信息。
具体例如，该第一指示信息指示目标标识信息，则终端设备根据目标标识信息从该N个COT共享信息中确定该目标COT共享信息。
在一些实施例中，上述S220具体可以包括：
该终端设备根据第二信息从该N个COT共享信息中确定该目标COT共享信息；其中，该第二信息包括但不限于以下至少之一：剩余COT时长，COT共享信息对应的优先级信息，最大剩余COT时长，最高优先级，最低优先级，提供COT共享信息的设备。
在一些实施例中，该第二信息可以是资源池配置信息或侧行BWP配置信息中指示的。
在一些实施例中，该COT共享信息对应的优先级信息为侧行优先级信息，或者，该COT共享信息对应的优先级信息为信道接入优先级信息。
具体例如，最高优先级可以是最高的侧行优先级，或者，最高优先级可以是最高的信道优先级。
具体例如，最低优先级可以是最低的侧行优先级，或者，最低优先级可以是最低的信道优先级。
在一些实施例中，该剩余COT时长是基于该终端设备的待传输侧行数据所在的时域资源确定的。
具体例如，终端设备根据N个COT共享信息中携带的第一剩余COT时长，确定N个第一剩余COT时长在该终端设备的待传输侧行数据所在的时隙位置所对应的N个第二剩余COT时长，终端设备根据该N个第二剩余COT时长中的最大值确定目标COT共享信息。
在一些实施例中，在第二信息至少包括剩余COT时长的情况下，即终端设备根据剩余COT时长确定目标COT共享信息。缺省的，或，根据协议规定，终端设备选取具有最大剩余时长的COT共享信息作为目标COT共享信息。
在一些实施例中，在该第二信息至少包括剩余COT时长的情况下，该终端设备将该N个COT共享信息中的第四COT共享信息确定为该目标COT共享信息。可选地，该第四COT共享信息为该N个COT共享信息中对应的剩余COT时长最长的COT共享信息。可选地，该第四COT共享信息为 该N个COT共享信息中对应的剩余COT时长大于或者等于第一门限值的COT共享信息。
在一些实施例中，该第四COT共享信息对应的剩余COT时长大于或者等于第一门限值，或者，该N个COT共享信息中的每个COT共享信息对应的剩余COT时长大于或者等于第一门限值。
在一些实施例中，在该N个COT共享信息中不包括剩余COT时长大于或者等于第一门限值的COT信息的情况下，该终端设备使用该第四COT共享信息对应的参数接入信道时不发送COT共享信息。也即，在终端设备检测到的COT共享信息中不包括满足第一门限值的COT共享信息，则终端设备使用COT共享信息接入信道时，不发送COT共享信息。
在一些实施例中，该第一门限值为基于预配置信息或网络设备配置信息获取的。例如，在资源池配置信息或侧行BWP配置信息中指示该第一门限值。
具体例如，如图14所示，UE-C(即本申请中的终端设备)根据资源选取或网络调度信息确定将要在时隙n+2发送侧行数据，侧行优先级的取值为2；UE-C在时隙n接收到UE-A发送的COT共享信息A，该COT共享信息A中包括的目标标识信息包括UE-C的标识，并且COT共享信息A中携带的优先级取值为4，因此UE-C可以使用UE-A发送的COT共享信息A进行信道接入，COT共享信息A对应的剩余COT时长(即图14中的第一剩余COT时长)为3个时隙，即从时隙n开始的3个时隙，包括时隙n至时隙n+2；进一步的，UE-C在时隙n+1接收到UE-B发送的COT共享信息B，该COT共享信息B中包括的目标标识信息包括UE-C的标识，并且COT共享信息B中携带的优先级取值为3，因此，UE-C可以使用UE-B发送的COT共享信息B进行信道接入，COT共享信息B对应的剩余COT时长(即图14中的第二剩余COT时长)为4个时隙，即从时隙n+1开始的4个时隙，包括时隙n+1至时隙n+4。由于时隙n+2位于共享COT对应的时长范围内，因此，UE-C在时隙n+2之前使用Type2A的信道接入类型接入信道，由于UE-C在时隙n+2进行信道接入，因此，UE-C根据COT共享信息A确定在时隙n+2时的剩余COT时长为1个时隙，根据COT共享信息B确定在时隙n+2时剩余COT时长为3个时隙，因此，UE-C选取对应剩余COT时长最大的COT共享信息对应的参数进行信道接入，即UE-C根据COT共享信息B对应的参数进行信道接入。
如图14所示，由于UE-C是根据UE-B发送的COT信息B对应的参数进行接入信道的，因此，在UE-C接入信道成功后，在发送侧行数据时，在侧行SCI中携带的COT共享信息是根据COT共享信息B确定的。例如，UE-C发送的COT共享信息中的优先级信息根据COT共享信息B中的优先级确定，即优先级值为3；UE-C发送的COT共享信息中的剩余COT时长根据COT共享信息B中的剩余COT时长确定，即剩余COT时长为3个时隙，包括时隙n+2至时隙n+4。
如图14所示，UE-C接收到UE-A发送的COT共享信息A，确定在时隙n+2时的第一剩余COT时长为1个时隙，UE-C接收到UE-B发送的COT共享信息B，确定在时隙n+2时的第二剩余COT时长为3个时隙。若UE-C使用UE-A发送的COT共享信息A进行信道接入，此时UE-C也无法发送COT共享信息，因为时隙n+2之后的剩余COT时长为0；而如果UE-C使用UE-B发送的COT共享信息B进行信道接入，则UE-C可以发送COT共享信息，并且指示剩余COT时长为3个时隙，包括时隙n+2后面的时隙n+3和时隙n+4，因此，其他终端仍然可以使用UE-C发送的COT共享信息接入信道。此时，可以通过配置第一门限值为2个时隙，只有确定的剩余COT时长大于或等于2个时隙的COT共享信息才是可用的COT共享信息，因此，本示例中，可用的COT共享信息即COT共享信息B，不包括COT共享信息A。
在一些实施例中，在资源池配置信息包括的一个信息元素指示剩余COT时长或COT时长，即终端设备根据剩余COT时长或COT时长确定使用的COT共享信息，缺省的，或根据协议规定，终端设备选取具有最大剩余时长的COT共享信息作为使用的COT共享信息。
在一些实施例中，在该第二信息至少包括最大剩余COT时长的情况下，该终端设备将该N个COT共享信息中对应的剩余COT时长最大的COT共享信息确定为该目标COT共享信息。
在一些实施例中，在资源池配置信息包括的一个信息元素指示最大剩余时长，终端设备选取具有最大剩余COT时长的COT共享信息作为使用的COT共享信息。
在一些实施例中，在第二信息至少包括COT共享信息对应的优先级信息的情况下，即终端设备根据COT共享信息对应的优先级信息确定目标COT共享信息。缺省的，或，根据协议规定，终端设备选取具有最低优先级的COT共享信息作为目标COT共享信息，或者，终端设备选取具有最高优先级的COT共享信息作为目标COT共享信息。
在一些实施例中，在资源池配置信息包括的一个信息元素指示优先级，该优先级例如表示侧行优先级，即终端设备根据侧行优先级确定使用的COT共享信息，缺省的，或根据协议规定，终端设备选取最低侧行优先级或最高侧行优先级对应的COT共享信息作为使用的COT共享信息。
在一些实施例中，在资源池配置信息包括的一个信息元素指示优先级，该优先级例如表示信道接 入优先级，即终端设备根据信道接入优先级确定使用的COT共享信息，缺省的，或根据协议规定，终端设备选取最低信道接入优先级或最高信道接入优先级对应的COT共享信息作为使用的COT共享信息。
在一些实施例中，在该第二信息至少包括COT共享信息对应的优先级信息的情况下，该终端设备将该N个COT共享信息中的第五COT共享信息确定为该目标COT共享信息；其中，该第五COT共享信息为该N个COT共享信息中对应的优先级最低的COT共享信息，或者，该第五COT共享信息为该N个COT共享信息中对应的优先级最高的COT共享信息。
具体例如，该五COT共享信息为该N个COT共享信息中对应的侧行优先级最低的COT共享信息，或者，该五COT共享信息为该N个COT共享信息中对应的信道优先级最低的COT共享信息。
具体例如，该五COT共享信息为该N个COT共享信息中对应的侧行优先级最高的COT共享信息，或者，该五COT共享信息为该N个COT共享信息中对应的信道优先级最高的COT共享信息。
应理解，侧行系统中，优先级的取值越高表示对应的优先级越低；对于信道接入等级，信道接入等级的取值越高表示对应的信道接入等级越低。
例如，当终端设备确定COT共享信息时，根据最低优先级确定使用的COT共享信息，使得该终端设备在发送COT共享信息时，其COT共享信息中携带的优先级信息也对应于该最低优先级，从而使得更多的终端可以使用该COT共享信息。从而可以提高其他终端成功接入信道的概率。
又例如，当终端设备确定COT共享信息时，根据最高优先级确定使用的COT共享信息，使得该终端设备在发送COT共享信息时，其COT共享信息中携带的优先级信息也对应于该最高优先级，只有优先级高于该最高优先级的终端设备可以使用该COT共享信息，从而降低其他终端接入信道的数量或成功概率，可以降低系统的拥塞等级，保证高优先级的终端的传输性能。
在一些实施例中，在该第二信息至少包括最高优先级的情况下，该终端设备将该N个COT共享信息中对应的侧行优先级最高的COT共享信息确定为该目标COT共享信息；或者，该终端设备将该N个COT共享信息中对应的信道优先级最高的COT共享信息确定为该目标COT共享信息。

在一实施例中，在资源池配置信息包括的一个信息元素指示最低优先级，优先级例如表示侧行优先级或信道接入优先级，即终端设备选取最低优先级对应的COT共享信息作为使用的COT共享信息。
在一些实施例中，在该第二信息至少包括提供COT共享信息的设备的情况下，该终端设备将该N个COT共享信息中由网络设备提供的COT共享信息确定为该目标COT共享信息。
具体例如，当网络设备发起COT共享时，网络设备可以通过下行控制信息(Downlink Control Information，DCI)或无线资源控制(Radio Resource Control，RRC)信令为各个终端发送相应的COT共享信息，由于网络设备可以为所有的终端指示相同的COT共享信息，即保证小区内的终端可以基于相同的COT共享信息进行信道接入，因此，当终端接收到多个COT共享信息时，如果其中包括网络设备发送的COT共享信息，终端可以基于网络设备发送的COT共享信息进行信道接入。
在一些实施例中，该终端设备从资源池配置信息或侧行BWP配置信息中获取第二指示信息；其中，该第二指示信息用于指示该终端设备根据该第二信息从该N个COT共享信息中确定该目标COT共享信息。也即，在获知该第二指示信息所指示的内容之后，该终端设备根据该第二信息从该N个COT共享信息中确定该目标COT共享信息。
具体例如，该第二指示信息可以是资源池配置信息或侧行BWP配置信息中的一个或多个信息元素(IE)，其中，该信息元素可以是字段或元素或域，本申请对此并不限定。
具体例如，该第二指示信息指示剩余COT时长，则终端设备根据剩余COT时长从该N个COT共享信息中确定该目标COT共享信息。
具体例如，该第二指示信息指示COT共享信息对应的优先级信息，则终端设备根据COT共享信息对应的优先级信息从该N个COT共享信息中确定该目标COT共享信息。
具体例如，该第二指示信息指示最大剩余COT时长，则终端设备根据最大剩余COT时长从该N个COT共享信息中确定该目标COT共享信息。
具体例如，该第二指示信息指示最高优先级，则终端设备根据最高优先级从该N个COT共享信息中确定该目标COT共享信息。
具体例如，该第二指示信息指示最低优先级，则终端设备根据最低优先级从该N个COT共享信 息中确定该目标COT共享信息。

在一些实施例中，该M个COT共享信息中的每个COT共享信息对应一个第二优先级信息。
在一些实施例中，该M个COT共享信息对应的第二优先级信息也可以是基于资源池配置信息或侧行BWP配置信息确定的，或者，该M个COT共享信息对应的第二优先级信息也可以是从资源池配置信息或侧行BWP配置信息中获取的。
具体例如，对于该M个COT共享信息中的第m个COT共享信息，根据该第m个COT共享信息中携带的优先级确定第二优先级信息，若终端设备的待传输侧行数据对应的优先级高于或等于该第二优先级信息对应的优先级，则将该第m个COT共享信息作为N个COT共享信息中的一个COT共享信息；否则不能将该第m个COT共享信息作为N个COT共享信息中的一个COT共享信息。

在一些实施例中，与所述M个COT共享信息中的每个COT共享信息同时发送的SCI中包括目标标识信息；在所述第三信息至少包括所述终端设备的标识信息的情况下，与所述N个COT共享信息中的每个COT共享信息同时发送的SCI中所包括的所述目标标识信息对应的标识包括所述终端设备的标识。应理解，目标标识信息所包括的终端标识信息可以是终端标识信息的部分信息，或者，目标标识信息所包括的组标识信息可以是组标识信息的部分信息，或者，目标标识信息所包括的业务类型信息可以是业务类型信息的部分信息，或者，目标标识信息所包括的Zone ID信息可以是Zone ID信息的部分信息。
在一些实施例中，该M个COT共享信息中的每个COT共享信息包括目标标识信息；在该第三信息至少包括该终端设备的标识信息的情况下，该N个COT共享信息所包括的该目标标识信息对应的标识包括该终端设备的标识。具体例如，该目标标识信息包括允许使用对应的COT共享信息的终端标识信息；或者，该目标标识信息包括允许使用对应的COT共享信息的终端组的标识信息。
具体例如，对于该M个COT共享信息中的第m个COT共享信息，根据该第m个COT共享信息中携带的目标标识信息确定是否可以将该第m个COT共享信息作为N个COT共享信息中的一个COT共享信息。例如，该第m个COT共享信息中携带的目标标识信息包括终端标识信息，只有该终 端标识信息对应的终端为该终端设备的情况下，可以将该第m个COT共享信息作为N个COT共享信息中的一个COT共享信息。又例如，该第m个COT共享信息中携带的目标标识信息包括组标识信息，只有该终端设备属于该组标识信息对应的通信组的情况下，可以将该第m个COT共享信息作为N个COT共享信息中的一个COT共享信息。又例如，该第m个COT共享信息中携带的目标标识信息包括业务类型信息，只有该终端设备传输该业务类型信息对应的业务类型的业务的情况下，可以将该第m个COT共享信息作为N个COT共享信息中的一个COT共享信息。又例如，该第m个COT共享信息中携带的目标标识信息包括Zone ID信息，只有该终端设备位于该Zone ID信息对应的区域内的情况下，可以将该第m个COT共享信息作为N个COT共享信息中的一个COT共享信息。应理解，目标标识信息所包括的终端标识信息可以是终端标识信息的部分信息，或者，目标标识信息所包括的组标识信息可以是组标识信息的部分信息，或者，目标标识信息所包括的业务类型信息可以是业务类型信息的部分信息，或者，目标标识信息所包括的Zone ID信息可以是Zone ID信息的部分信息。
例如，终端设备的终端标识为a，且该终端设备获取了4个COT共享信息(即M＝4)，分别记为COT共享信息A、COT共享信息B、COT共享信息C、COT共享信息D，以及，COT共享信息A中携带的目标标识信息包括终端标识a，COT共享信息B中携带的目标标识信息包括终端标识a，COT共享信息C中携带的目标标识信息包括终端标识c，COT共享信息D中携带的目标标识信息包括终端标识d。则将COT共享信息A和COT共享信息B分别作为N个COT共享信息中的一个COT共享信息，且不能将COT共享信息C和COT共享信息D作为N个COT共享信息中的COT共享信息。
在一些实施例中，与所述N个COT共享信息中的每个COT共享信息同时发送的PSCCH或PSSCH的传输资源对应的资源块集合包括所述终端设备确定使用的资源块集合。因此，可以从M个COT共享信息中确定N个COT共享信息。
