在SL通信中可以支持UE间协作(inter-UE coordination)功能，例如，两个或更多个UE之间在资源分配和/或预留和/或指示上进行协作，以提高资源分配和/或预留和/或指示的效率，和/或减少资源分配和/或预留和/或指示的冲突，等等。具体地，例如，一个UE(例如，称为UE-A)可以向一个或多个其他UE(例如，统一称为UE-B；又如，分别称为UE-B1，UE-B2，……)分别传输一个“协作信息指示”(coordination information indication)，其中包含的协作信息可以显式或隐式地指示(或对应，或关联)一个或多个资源集合(例如称为“协作资源集合”)。一个协作信息 指示(或者一个协作资源集合)可以对应一个协作类型(或者称为“协作方式”，或者称为“协作方案”)。一个资源集合中的资源可以是UE-A检测到冲突的资源(相应地，所述协作信息指示可以称为“资源冲突指示”)，或者是UE-A希望UE-B优先使用的资源(相应地，所述协作信息指示可以称为“优先资源指示”)，或者是UE-A希望UE-B不要使用的资源(相应地，所述协作信息指示可以称为“非优先资源指示”)。协作信息可以包含在控制信息中。其中，所述控制信息可以是物理层控制信息，或者高层控制信息。例如，协作信息可以包含在第一阶段SCI中。又如，协作信息可以包含在第二阶段SCI中。又如，协作信息可以包含在SFCI(sidelink feedback control information，侧行反馈控制信息)中。又如，协作信息可以包含在其他控制信息(例如称为SCCI，sidelink coordination control information，侧行协作控制信息)中。
协作信息可以包含在一个高层(例如MAC层，又如RRC层)消息中。例如，协作信息可以包含在一个MAC CE(MAC Control Element，MAC控制元素)中。又如，协作信息可以包含在一个RRC消息中。
一个协作信息指示可以由一个物理层信道(或者一个所述物理层信道的传输)携带，或者由一个物理层信号(或者一个所述物理层信号的传输)携带。为方便起见，可以称所述物理层信道/信号为“物理侧行协作信息信道/信号”(Physical Sidelink Coordination Information Channel/Signal，PSCICHS)。
一个PSCICHS(或者一个PSCICHS传输)所占用的资源(例如一个时域和/或频域和/或码域和/或空域资源)可以称为一个“PSCICHS资源” (PSCICHS resource)。可选地，一个PSCICHS资源可以称为一个“PSCICHS时机”(PSCICHS occasion)，或者“PSCICHS时机资源”(PSCICHS occasion resource)，或者“PSCICHS资源时机”(PSCICHS resource occasion)；对于一个传输PSCICHS的UE，一个PSCICHS资源可以称为一个“PSCICHS传输资源”(PSCICHS transmission resource)，或者“PSCICHS传输时机”(PSCICHS transmission occasion)，或者“PSCICHS传输时机资源”(PSCICHS transmission occasion resource)，或者“PSCICHS传输资源时机”(PSCICHS transmission resource occasion)；对于一个接收PSCICHS的UE，一个PSCICHS资源可以称为一个“PSCICHS接收资源”(PSCICHS reception resource)，或者“PSCICHS接收时机”(PSCICHS reception occasion)，或者“PSCICHS接收时机资源”(PSCICHS reception occasion resource)，或者“PSCICHS接收资源时机”(PSCICHS reception resource occasion)。
PSCICHS资源可以在一个SL载波中配置(例如在信息元素SL-FreqConfigCommon中配置，又如在信息元素SL-FreqConfig中配置)。一个SL载波中可以存在零个或一个或多个“PSCICHS配置”(PSCICHS configuration)。
PSCICHS资源可以在一个SL BWP中配置(例如在信息元素SL-BWP-Config中配置，又如在信息元素SL-BWP-Generic中配置)。一个SL BWP中可以存在零个或一个或多个PSCICHS配置，其中，对每一个PSCICHS配置，PSCICHS资源可以占用所述SL BWP中一个或多个资源池中配置的一个或多个子信道(或者，一个或多个资源块)，或者不占 用所述SL BWP中任何资源池中配置的任何一个子信道(或者，任何一个资源块)。

在时域，PSCICHS资源可以周期性地出现。一个有PSCICHS资源的时隙可以称为“PSCICHS资源时隙”(或者称为“PSCICHS时隙”)。对一个PSCICHS配置，在一个预定义的周期(例如一个SFN周期，又如一个DFN周期；例如持续时间为10240毫秒；例如从SFN＝0到SFN＝1023，又如从DFN＝0到DFN＝1023)内，PSCICHS时隙的集合可以记为

在频域，一个PSCICHS资源的大小(例如记为
例如表示
个子载波，或者
个资源块，或者
个资源块组，或者
个子信道)可以是一个预定义或配置或预配置的值，或者由一个或多个预定义或配置或预配置的值确定。例如，
个资源块。一个PSCICHS资源可以占用
个连续的子载波，或者
个连续的资源块，或者
个连续的资源块组，或者
个连续 的子信道。
在频域，一个PSCICHS配置可以包含
个PSCICHS资源，其中

个PSCICHS资源可以占用
个连续的子载波，或者
个连续的资源块，或者
个连续的资源块组，或者
个连续的子信道。
在码域，一个PSCICHS资源可以对应一个循环移位(cyclic shift)值，或者所述循环移位值的索引。其中，所述循环移位值可以用于确定一个在所述PSCICHS资源上的PSCICHS传输所对应的序列(sequence)，例如，所述序列可以是对一个预定义或配置或预配置的基序列(base sequence)进行相应的循环移位后得到，用于表示所述PSCICHS传输携带的协作信息中指示的一个值。可选地，一个“循环移位值”又可以称为一个“循环移位”。
在码域，一个PSCICHS资源可以对应一个循环移位对(cyclic shift pair)值，或者所述循环移位对值的索引。其中，所述循环移位对值可以对应两个循环移位值(例如0和6)，其中每个循环移位值可以用于确定一个在所述PSCICHS资源上的PSCICHS传输所对应的序列，例如，每个序列可以是对一个预定义或配置或预配置的基序列进行相应的循环移位后得到，用于表示所述PSCICHS传输携带的协作信息中指示的一个值。可选地，一个“循环移位对值”又可以称为一个“循环移位对”。

一个PSCICHS传输可以关联一个优先级。所述优先级可以用一个优先级值表示。
一个协作信息指示可以由传输所述协作信息的UE自主触发。例如，若UE-A检测到UE-B1和UE-B2分别通过SCI指示(或者预留，或者分配)的资源存在冲突，则所述UE-A可以通过一个或多个携带协作信息的SL传输指示所述冲突。
一个协作信息指示可以由一个“协作请求指示”(coordination request indication)触发。例如，UE-B向UE-A传输一个协作请求指示(例如，其中可以包含一个协作类型指示，例如“资源冲突”)，作为回应，UE-A可以检测UE-B和其他UE(例如包括UE-A，又如不包括UE-A)是否存在资源冲突，并且将检测的结果包含在协作信息指示中向UE-B传输。
可选地，协作请求可以认为是一种使能(enable)UE间协作功能的方式。在这个意义上，协作请求可以称为“协作使能”。例如，一个不支持UE间协作功能的UE不会传输协作请求指示，而一个支持UE间协作功能的UE可以传输协作请求指示，或者不传输协作请求指示。可选地，为避免传输不必要的协作信息指示，可以只向涉及到一次资源冲突的部分UE传输协作信息指示。例如，若UE-A检测到SCI
1预留的资源R
1与SCI
2预留的资源R
2之间存在资源冲突，且SCI
1中指示了“协作使能”，SCI
2中未指示“协作使能”(或者SCI
2中指示了“协作去使能”)，则UE-A可以传输SCI
1(或者R
1)关联的协作信息指示，而不传输SCI
2(或者R
2)关联的协作信息指示。
协作请求可以包含在控制信息中。其中，所述控制信息可以是物理层控制信息，或者高层控制信息。例如，协作请求可以包含在第一阶段SCI中。又如，协作请求可以包含在第二阶段SCI中。又如，协作请求可以包含在SFCI中。又如，协作请求可以包含在其他控制信息(例如SCCI中。
协作请求可以包含在一个高层(例如MAC层，又如RRC层)消息中。例如，协作请求可以包含在一个MAC CE中。又如，协作请求可以包含在一个RRC消息中。
一个协作请求指示可以由一个物理层信道(或者一个所述物理层信道的传输)携带，或者由一个物理层信号(或者一个所述物理层信号的传输)携带。为方便起见，可以称所述物理层信道/信号为“物理侧行协作请求信道/信号”(Physical Sidelink Coordination Request Channel/Signal，PSCRCHS)。可选地，根据协作类型的不同，PSCRCHS可以是不同的物理层信道或信号，例如，对于优先资源指示和/或非优先资源指示，PSCRCHS可以是PSCCH，或者PSSCH，或者PSCCH+PSSCH，或者一个其他的物理层信道，或者一个物理层信号；对于资源冲突指示，PSCRCHS可以是PSFCH，或者一个其他的物理层信道，或者一个物理层信号。
一个PSCRCHS(或者一个PSCRCHS传输)所占用的资源(例如一个时域和/或频域和/或码域和/或空域资源)可以称为一个“PSCRCHS资源”(PSCRCHS resource)。可选地，一个PSCRCHS资源可以称为一个“PSCRCHS时机”(PSCRCHS occasion)，或者“PSCRCHS时机资源”(PSCRCHS occasion resource)，或者“PSCRCHS资源时机”(PSCRCHS resource occasion)；对于一个传输PSCRCHS的UE，一个PSCRCHS资源可以称为一个“PSCRCHS传输资源”(PSCRCHS transmission resource)，或者“PSCRCHS传输时机”(PSCRCHS transmission occasion)，或者“PSCRCHS传输时机资源”(PSCRCHS transmission occasion resource)，或者“PSCRCHS传输资源时机”(PSCRCHS transmission resource occasion)；对于一个接收PSCRCHS的UE，一个PSCRCHS资源可以称为一个“PSCRCHS接收资源”(PSCRCHS reception resource)，或者 “PSCRCHS接收时机”(PSCRCHS reception occasion)，或者“PSCRCHS接收时机资源”(PSCRCHS reception occasion resource)，或者“PSCRCHS接收资源时机”(PSCRCHS reception resource occasion)。
PSCRCHS资源可以在一个SL载波中配置(例如在信息元素SL-FreqConfigCommon中配置，又如在信息元素SL-FreqConfig中配置)。一个SL载波中可以存在零个或一个或多个“PSCRCHS配置”(PSCRCHS configuration)。
PSCRCHS资源可以在一个SL BWP中配置(例如在信息元素SL-BWP-Config中配置，又如在信息元素SL-BWP-Generic中配置)。一个SL BWP中可以存在零个或一个或多个PSCRCHS配置，其中，对每一个PSCRCHS配置，PSCRCHS资源可以占用所述SL BWP中一个或多个资源池中配置的一个或多个子信道(或者，一个或多个资源块)，或者不占用所述SL BWP中任何资源池中配置的任何一个子信道(或者，任何一个资源块)。
PSCRCHS资源可以在一个资源池中配置(例如在信息元素SL-ResourcePool中配置)。一个资源池中可以存在零个或一个PSCRCHS配置，其中，PSCRCHS资源可以占用所述资源池中配置的一个或多个子信道(或者，一个或多个资源块)，或者不占用所述资源池中配置的任何一个子信道(或者，任何一个资源块)。
可以通过一个高层协议参数(例如称为sl-ueCoordConfig)打开(或者“使能”，或者“配置”)或关闭(或者去使能)UE间的协作功能。例如，若所述参数sl-ueCoordConfig不存在(或者未配置)，则表示UE 间的协作功能未打开。又如，若所述参数sl-ueCoordConfig存在(或者已配置)，则表示UE间的协作功能已打开。又如，若所述参数sl-ueCoordConfig(或所述参数sl-ueCoordConfig对应的信息元素中的某个参数)的取值为一个预定义的值(例如，“disabled”，“false”等)，则表示UE间的协作功能未打开。又如，若所述参数sl-ueCoordConfig(或所述参数sl-ueCoordConfig对应的信息元素中的某个参数)的取值为一个预定义的值(例如，“enabled”，“true”等)，则表示UE间的协作功能已打开。

可选地，在本发明的实施例一中，所述第二协议层实体是物理层协议实体，或者MAC层协议实体，或者RLC层协议实体，或者PDCP层协议实体，或者RRC层协议实体，或者PC5-RRC层协议实体，或者PC5-S层协议实体。
可选地，在本发明的实施例一中，所述步骤S101、所述步骤S103和所述步骤S105(在适用的情况下)由所述UE的第二协议层实体执行。
这样，根据实施例一所述，本发明提供了一种方法，通过利用两个或者多个发生冲突的资源的特定参数(例如起始子信道等)确定用于传输协作信息指示的一个或多个资源，有效地减小了需要传输的协作信息指示的个数以及相应的资源的使用，提高了UE间协作的效率。
在本发明中，“UE间协作”以及其他相关的术语(例如“协作信息指示”、“协作请求指示”、“优先资源指示”、“非优先资源指示”、 “资源冲突指示”、“侧行协作控制信息”、“物理侧行协作信息信道/信号”、“物理侧行协作请求信道/信号”等)可以由其在系统中的功能和/或相应的流程和/或相应的信令进行定义。这些术语在应用到具体的系统中时，可以替换为其他的名称。
[变形例]
下面，利用图2来说明作为一种变形例的可执行本发明上面所详细描述的用户设备执行的方法的用户设备。
图2是表示本发明所涉及的用户设备UE的框图。
如图2所示，该用户设备UE20包括处理器201和存储器202。处理器201例如可以包括微处理器、微控制器、嵌入式处理器等。存储器202例如可以包括易失性存储器(如随机存取存储器RAM)、硬盘驱动器(HDD)、非易失性存储器(如闪速存储器)、或其他存储器等。存储器202上存储有程序指令。该指令在由处理器201运行时，可以执行本发明详细描述的由用户设备执行的上述方法。
上文已经结合优选实施例对本发明的方法和涉及的设备进行了描述。本领域技术人员可以理解，上面示出的方法仅是示例性的，而且以上说明的各实施例在不发生矛盾的情况下能够相互组合。本发明的方法并不局限于上面示出的步骤和顺序。上面示出的网络节点和用户设备可以包括更多的模块，例如还可以包括可以开发的或者将来开发的可用于基站、AMF(Access and Mobility Management Function，接入和移动性管理功能)、 UPF(User Plane Function，用户面功能)、MME(Mobility Management Entity，移动管理实体)、S-GW(Serving Gateway，服务网关)或UE的模块等等。上文中示出的各种标识仅是示例性的而不是限制性的，本发明并不局限于作为这些标识的示例的具体信元。本领域技术人员根据所示实施例的教导可以进行许多变化和修改。本领域技术人员应该理解，数学表达式或数学等式或数学不等式的部分或全部可以进行一定程度的简化或者变换或者重写，例如合并常数项，又如交换两个加法项，又如交换两个乘法项，又如将一个项改变正负号后从等式或不等式的左边移动到右边，又如将一个项改变正负号后从等式或不等式的右边移动到左边，等等；简化或者变换或者重写前后的数学表达式或数学等式或数学不等式可以认为是等同的。本领域技术人员应该理解，一个集合的子集可以是该集合本身，例如，A＝{a
1，a
2}的子集可以是{a
1，a
2}，或者{a
1}，或者{a
2}，或者空集。
应该理解，本发明的上述实施例可以通过软件、硬件或者软件和硬件两者的结合来实现。例如，上述实施例中的基站和用户设备内部的各种组件可以通过多种器件来实现，这些器件包括但不限于：模拟电路器件、数字电路器件、数字信号处理(DSP)电路、可编程处理器、专用集成电路(ASIC)、现场可编程门阵列(FPGA)、可编程逻辑器件(CPLD)，等等。
在本发明中，“基站”可以指具有一定发射功率和一定覆盖面积的移动通信数据和/或控制交换中心，例如包括资源分配调度、数据接收发送等功能。“用户设备”可以指用户移动终端，例如包括移动电话、笔记本 等可以与基站或者微基站进行无线通信的终端设备。
此外，这里所公开的本发明的实施例可以在计算机程序产品上实现。更具体地，该计算机程序产品是如下的一种产品：具有计算机可读介质，计算机可读介质上编码有计算机程序逻辑，当在计算设备上执行时，该计算机程序逻辑提供相关的操作以实现本发明的上述技术方案。当在计算系统的至少一个处理器上执行时，计算机程序逻辑使得处理器执行本发明实施例所述的操作(方法)。本发明的这种设置典型地提供为设置或编码在例如光介质(例如CD-ROM)、软盘或硬盘等的计算机可读介质上的软件、代码和/或其他数据结构、或者诸如一个或多个ROM或RAM或PROM芯片上的固件或微代码的其他介质、或一个或多个模块中的可下载的软件图像、共享数据库等。软件或固件或这种配置可安装在计算设备上，以使得计算设备中的一个或多个处理器执行本发明实施例所描述的技术方案。
此外，上述每个实施例中所使用的基站设备和终端设备的每个功能模块或各个特征可以由电路实现或执行，所述电路通常为一个或多个集成电路。设计用于执行本说明书中所描述的各个功能的电路可以包括通用处理器、数字信号处理器(DSP)、专用集成电路(ASIC)或通用集成电路、现场可编程门阵列(FPGA)或其他可编程逻辑器件、分立的门或晶体管逻辑、或分立的硬件组件、或以上器件的任意组合。通用处理器可以是微处理器，或者所述处理器可以是现有的处理器、控制器、微控制器或状态机。上述通用处理器或每个电路可以由数字电路配置，或者可以由逻辑电路配置。此外，当由于半导体技术的进步，出现了能够替代目前的集成电路的先进技术时，本发明也可以使用利用该先进技术得到的集成电路。
尽管以上已经结合本发明的优选实施例示出了本发明，但是本领域的技术人员将会理解，在不脱离本发明的精神和范围的情况下，可以对本发明进行各种修改、替换和改变。因此，本发明不应由上述实施例来限定，而应由所附权利要求及其等价物来限定。
