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，若只有一个其他UE，可以称为UE-B；又如，若有多于一个其他UE，可以分别称为UE-B1，UE-B2，……)分别传输一个“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”)。
可选地，一个协作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”(resource conflict  indication，或者称为“冲突指示”，conflict indication)。一个资源冲突(或者称为“冲突”)可以与一个或多个资源有关，UE-A检测到所述资源冲突后可以传输一个或多个资源冲突指示，其中每个资源冲突指示对应的协作资源集合中可以包含一个或多个与所述资源冲突有关的资源。
例如，对于UE-A检测到的UE-B1预留的资源R 1、UE-B 2预留的资源R 2、……、UE-B n预留的资源R n，当下面中的一项或多项成立时，所述UE-A可以认为所述资源R 1、所述资源R 2、……、所述资源R n出现了资源冲突：
●所述资源R 1、所述资源R 2、……、所述资源R n中的任意一个资源和所述资源R 1、所述资源R 2、……、所述资源R n中的其他一个或多个资源在时域和/或频域重叠。
●所述资源R 1、所述资源R 2、……、所述资源R n中的任意一个资源和所述资源R 1、所述资源R 2、……、所述资源R n中的其他所有资源在时域和/或频域重叠。
●UE-A是所述资源R 1、所述资源R 2、……、所述资源R n中的一个或多个资源分别要携带的传输块的目标UE。例如，UE-A可以根据预留一个资源的SCI中指示的目标ID和/或源ID确定自己是否所述资源要携带的传输块的目标UE。
●UE-A是所述资源R 1、所述资源R 2、……、所述资源R n中的所有资源分别要携带的传输块的目标UE。
又如，若UE-A检测到UE-B 1预留了资源R 1，当下面中的一项或多项成立时，所述UE-A可以认为所述资源R 1出现了资源冲突：
●UE-A是所述资源R 1要携带的传输块的目标UE。
●UE-A需要在与所述资源R 1重叠的时间资源上执行UL传输，而且，所述UL传输的优先级高于在所述资源R 1上的SL接收的优先级。
●由于UE能力限制，UE-A无法同时执行UL传输和SL接收。
●所述UE-A需要在与所述资源R 1重叠的时间资源上执行SL传输，而且，所述SL传输的优先级高于在所述资源R 1上的SL接收的优先级。
●由于UE能力限制，UE-A无法同时执行SL传输和SL接收。
可选地，当UE-A检测到UE-B 1所预留的资源R 1、UE-B 2所预留的资源R 2、……、UE-B n所预留的资源R n出现了资源冲突时，所述UE-A可以向所述UE-B 1、所述UE-B 2、……、所述UE-B n中的一个或多个传输资源冲突指示。可选地，所述UE-A在所述资源R 1关联的一个“资源冲突指示资源”上向所述UE-B 1传输资源冲突指示，在所述资源R 2关联的一个“资源冲突指示资源”上向所述UE-B 2传输资源冲突指示，……，在所述资源R n关联的一个“资源冲突指示资源”上向所述UE-B n传输资源冲突指示。由于UE传输能力和/或优先级等原因，UE-A可以丢弃一个或多个资源冲突指示。
可选地，一个资源冲突可以是一个已经过去的时隙上的资源冲突，相应的资源冲突检测可以称为“冲突后检测”(post-conflict detection)。
可选地，一个资源冲突可以是一个将来的时隙上的冲突(或者称为“潜在的冲突”，或者称为“预期的冲突”)，相应的资源冲突检测可以称为 “冲突前检测”(pre-conflict detection)。
可选地，一个资源冲突可以是在同一个资源池上的资源冲突，或者是在不同资源池(例如一个SL载波或SL BWP上的两个不同资源池)上的资源冲突，或者是在两个不同的载波(例如一个SL载波和一个UL载波)上的资源冲突。
可选地，一个协作资源集合中的资源可以是UE-A希望UE-B优先使用的资源(“preferred resource”。相应地，所述协作信息指示可以称为“优先资源指示”)。例如，所述UE-A希望所述UE-B在进行资源选择(例如，为所述UE-B到所述UE-A的SL传输进行资源选择)时选择(或优先选择)所述资源。
可选地，一个协作资源集合中的资源可以是UE-A希望UE-B不要使用(或最好不要使用)的资源(“non-preferred resource”。相应地，所述协作信息指示可以称为“非优先资源指示”)。例如，所述UE-A希望所述UE-B在进行资源选择(例如，为所述UE-B到所述UE-A的SL传输进行资源选择)时排除(或优先排除)所述资源。
可选地，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。
可选地，协作信息可以包含在高层(例如MAC层，又如RRC层) 信令中。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。
可选地，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)。可选地，根据协作类型的不同，PSCICHS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，PSCICHS可以是PSCCH，或者PSSCH，或者PSCCH+PSSCH，或者PSFCH，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，PSCICHS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。
可选地，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(或者所述PSCICHS资源所对应的时域资源，例如所述PSCICHS资源所在的时隙，又如所述PSCICHS资源所在的一个或多个符号)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(或者所述PSCICHS资源所对应的时域资源，例如所述PSCICHS资源所在的时隙，又如所述PSCICHS资源所在的一个或多个符号)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(或者所述PSCICHS资源所对应的时域资源，例如所述PSCICHS资源所在的时隙，又如所述PSCICHS资源所在的一个或多个符号)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)。
可选地，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)。
可选地，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)。
可选地，PSCICHS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PSCICHS配置，其中，PSCICHS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)。
可选地，可以按预定义或配置或预配置的方式确定一个PSCICHS传输和/或相应的PSCICHS资源所对应的PSCICHS配置。例如，资源池u 1中不存在任何PSCICHS配置，而资源池u 2中存在一个PSCICHS配置，相应地，所述资源池u 1不支持协作信息指示(例如，无法指示所述资源池u 1中的资源冲突)，而所述资源池u 2支持协作信息指示(例如，所述资源池u 2中检测到的一个资源冲突可以通过所述资源池u 2中的一个或多个PSCICHS传输指示)。又如，资源池u 1中不存在任何PSCICHS配置，而资源池u 2和资源池u 3中分别存在一个PSCICHS配置，相应地，与所述资源池u 1有关的协作信息(例如，所述资源池u 1中检测到的一个资源冲突所对应的资源冲突指示)可以预定义或配置或预配置为通过所述资源池u 2中的一个或多个PSCICHS传输指示；与所述资源池u 2有关的协作信息(例如，所述资源池u 2中检测到的一个资源冲突所对应的资源冲突指示)可以(缺省地)通过所述资源池u 2中的一个或多个PSCICHS传输指示，或者预定义或配置或预配置为通过所述资源池u 3中的一个或多个PSCICHS传输指示。又如，资源池u 1中不存在任何PSCICHS配置，而所述资源池u 1所在的SL BWP中存在一个PSCICHS配置，相应地，与所述资源池u 1有关的协作信息(例如，所述资源池u 1中检测到的一个资源冲突所对应的资源冲突指示)可以预定义或配置或预配置为通过所述SL  BWP中的一个或多个PSCICHS传输指示。又如，协作信息可以在一个SL BWP内定义(例如，跨资源池定义，具体地，例如，一个资源冲突可以对应在所述SL BWP内的资源池u 1中的一个资源与在所述SL BWP内的资源池u 2中的一个资源的冲突，例如所述两个资源在时间上重叠)，相应地，协作信息(例如，一个资源冲突所对应的资源冲突指示)可以预定义或配置或预配置为通过所述SL BWP中的一个或多个PSCICHS传输指示。
可选地，PSCICHS资源可以通过感测(sensing)和/或资源选择机制确定。例如，一个PSCICHS可以是一个PSCCH和/或一个PSSCH。
可选地，在时域，PSCICHS资源可以周期性地出现。一个配置了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

例如，一个PSCICHS配置可以包含一个PSCICHS时隙周期(例如记为

可选地，在本发明的实施例一中，对于集合A和集合B，“B-A”可以表示属于所述集合B、但不属于所述集合A的所有元素组成的集合。
这样，根据实施例一所述，本发明提供了一种方法，通过为每一个资源冲突确定一个优先级，进而以所述优先级为依据确定是否传输所述资源冲突触发的一个或多个资源冲突指示，有效地解决了在重叠的时域资源上要传输多个资源冲突触发的资源冲突指示时的优先次序问题。
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。
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。
