边链路中的发送设备可以基于感知(sensing)结果，自主地对用于信息发送的时频资源进行选择。其中，感知包括监听(monitor)SCI、测量参考信号接收功率(RSRP，Reference Signal Received Power)和测量接收信号强度指示(RSSI，Received Signal Strength Indicator)等。通过感知，可以在资源选择时避开已经被其他设备预留的资源，因此可以避免与其他设备的边链路传输发生碰撞，从而避免干扰。
应该注意，上面对技术背景的介绍只是为了方便对本申请的技术方案进行清楚、完整的说明，并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本申请的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
发明内容
在当前的NR V2X中，可能会由于终端设备(UE)的感知范围受限导致资源碰撞的出现，降低了可靠性，因此，对可靠性需求较大的业务的性能会有影响。目前，提出了一种增强的机制来减少碰撞的概率，增大可靠性。
图1是上述增强机制应用场景示意图，如图1所示，UE B要发送数据给UE A，UE A附近还有另一个UE B无法感知到的UE C，换句话说对于UE B来说，UE C是一个“隐藏终端”，如果UE B和UE C都需要发送数据，因为互相之间无法感知(sensing)到，那么可能会导致UE B选择的资源与UE C选择的资源重合，这样UE B和UE C发送给UE A的数据之间会产生干扰，因此，目前的增加机制是，UE A通过感知过程获知UE C的资源使用情况，将UE C的资源使用情况添加到辅助信息中发送给UE  B，UE B则能够在资源选择过程中将这些被UE C或UE C检测到的其周围的UE占用的资源集合排除，降低了发生碰撞的概率，增加了可靠性。但目前还没有提出如何确定辅助信息内感知的资源集合的方法以及如何发送上述辅助信息的方法。
针对上述问题的至少之一，本申请实施例提供一种信息发送方法及装置。
根据本申请实施例的一个方面，提供一种信息发送方法，包括：
第二UE根据第一发送优先级确定第二资源集合；
该第二UE将辅助信息发送给第一UE，该辅助信息包括该第二资源集合中资源的时频域信息，该第二资源集合用于该第一UE确定发送的第一边链路数据的第一候选资源集合，其中，该第一发送优先级根据该第一UE发送该第一边链路数据的优先级确定。

根据本申请实施例的一个方面，提供一种资源确定方法，包括：
第一UE接收第二UE发送的辅助信息；其中，该辅助信息包括第二资源集合中资源的时频域信息，该第二资源集合是该第二UE根据第一发送优先级确定的，该第一发送优先级根据该第一UE发送第一边链路数据的优先级确定；
该第一UE根据该第二资源集合确定发送该第一边链路数据的第一候选资源集合。
根据本申请实施例的另一个方面，提供一种资源确定装置，应用于第一UE，包括：

该第二UE根据处理结果向该第一UE发送该辅助信息，或者不发送该辅助信息，或者对该辅助信息的发送进行功率缩减。
根据本申请实施例的另一个方面，提供一种信息发送装置，应用于第二UE，包括：
第一处理单元，其用于根据第一发送优先级执行与向第一UE发送辅助信息相关的处理；其中，该辅助信息用于该第一UE确定发送的第一边链路数据的第一候选资源集合，该第一发送优先级根据该第一UE发送该第一边链路数据的优先级确定；
第二处理单元，其用于根据处理结果向该第一UE发送该辅助信息，或者不发送该辅助信息，或者对该辅助信息的发送进行功率缩减。
本申请实施例的有益效果之一在于：终端设备不是根据该终端设备自身待发数据的优先级确定辅助信息内感知的资源集合或执行向对端终端设备发送辅助信息的处理，而是根据使用辅助信息确定发送数据资源的对端终端设备发送该数据的优先级来确定辅助信息内感知的资源集合或执行向对端终端设备发送辅助信息的处理，由此，能够考虑对端终端设备发送的业务来确定辅助信息内感知的资源集合以及发送上述辅助信息，以便该辅助信息能够更有效的辅助对端终端设备发送业务。

以下通过示例对本申请实施例的场景进行说明，但本申请不限于此。
图2是本申请实施例的通信系统的示意图，示意性说明了以终端设备和网络设备为例的情况，如图2所示，通信系统100可以包括网络设备101和终端设备102、103、104。为简单起见，图2仅以三个终端设备和一个网络设备为例进行说明，但本申请实施例不限于此。
在本申请实施例中，网络设备101和终端设备102、103之间可以进行现有的业务或者未来可实施的业务发送。例如，这些业务可以包括但不限于：增强的移动宽带(eMBB，enhanced Mobile Broadband)、大规模机器类型通信(mMTC，massive Machine Type Communication)和高可靠低时延通信(URLLC，Ultra-Reliable and Low-Latency Communication)，等等。
值得注意的是，图2示出了三个终端设备102、103、104均处于网络设备101的覆盖范围内，但本申请不限于此。三个终端设备102、103、104可以均不在网络设备101的覆盖范围内，或者一个终端设备102在网络设备101的覆盖范围之内而另外终 端设备103、104在网络设备101的覆盖范围之外。
在本申请实施例中，终端设备102、103、104之间可以进行边链路发送。例如，终端设备102、103、104可以都在网络设备101的覆盖范围之内进行边链路发送以实现V2X通信，也可以都在网络设备101的覆盖范围之外进行边链路发送以实现V2X通信，还可以一个终端设备102在网络设备101的覆盖范围之内而另外终端设备103、104在网络设备101的覆盖范围之外进行边链路发送以实现V2X通信。
在本申请实施例中，终端设备102和/或103和/或104可以自主选择边链路资源(即采用Mode 2)，在这种情况下边链路发送可以与网络设备101无关，即网络设备101是可选的。当然，本申请实施例也可以将自主选择边链路资源(即采用Mode 2)和由网络设备分配边链路资源(即采用Mode 1)结合起来；本申请实施例不对此进行限制。
在本申请实施例中，时间单元可以是子帧、时隙或者包含至少一个时域符号的集合。至少一个时域符号的集合也可以称为mini-slot或non-slot。例如，本申请实施例中的子帧和时隙可以互换使用，“时隙”也可以替换为“子帧”，本申请不限于此，还可以替换为其他的时间单元。此外，术语“时频资源”和“资源”可以互换使用。
在本申请实施例中，以“V2X”或“P2X”为例对边链路进行说明，但本申请不限于此，还可以适用于“V2X”或“P2X”以外的边链路场景。
在以下的说明中，在不引起混淆的情况下，术语“边链路”和“V2X”或“P2X”可以互换，术语“PSFCH”和“边链路反馈信道”可以互换，术语“PSCCH”和“边链路控制信道”或“边链路控制信息”可以互换，术语“PSSCH”和“边链路数据信道”或“边链路数据”也可以互换。
另外，发送(transmitting)或接收(receiving)PSSCH可以理解为发送或接收由PSSCH承载的边链路数据；发送或接收PSFCH可以理解为发送或接收由PSFCH承载的边链路反馈信息。
目前，终端设备能够通过感知检测+资源选择的过程来获得边链路发送资源，其中可以持续不断地进行感知(sensing)来获得资源池内资源的占用情况。例如，终端设备可以根据前一段时间内(称为感知窗)的资源占用情况来估计后一段时间内(称为选择窗)的资源占用情况。
终端设备例如通过第(n-1000)至第(n-1)个子帧或时隙(即感知窗，sensing window) 内的边链路控制信息(SCI，Sidelink Control Information)和对不同位置时频资源参考信号的检测，可以获得该感知窗的资源占用情况，进而可以估计出第(n+T1)至第(n+T2)个子帧或时隙(即选择窗，selection window)的资源占用情况。上述感知包括监听SCI、测量参考信号接收功率RSRP等。在某一时间单元内监听SCI有多种等价的表述，例如监听某一时间单元、在某一时间单元内接收SCI、在某一时间单元检测SCI、在某一时间单元内盲检SCI，等等。SCI可以是LTE V2X中的SCI，也可以是NR V2X中的1st stage SCI(SCI format 1A)，本申请不限于此。该感知检测+资源选择的过程包括：
例如，步骤1-物理层获得候选资源集合：
当有待发送的边链路数据时，终端设备的物理层从高层(例如介质访问控制(MAC，Media Access Control)层)获得资源选择的粒度R x,y；该粒度可以表示一个子帧内的一系列连续的子信道，每个子信道包括多于一个的连续物理资源块(PRB，Physical Resource Block)，PRB个数可以由资源池决定，资源池由网络设备(例如基站)配置或预配置；整个选择窗中的所有子帧内R x,y大小的资源(以下简称为R x,y候选资源)的集合被初始化定义为Set A。
终端设备可以根据在待发送数据到达之前在该感知窗内进行检测的结果，排除Set A中的部分候选资源。例如，以下的R x,y候选资源需要被排除：
——终端设备在感知窗内的发送子帧所对应的在选择窗中可能被进行资源预留的子帧内的所有R x,y候选资源；
——终端设备在感知窗内进行检测的子帧中的某个R x,y候选资源，其中在该R x,y候选资源上检测到SCI预留了当前选择窗内对应的子帧，且指示的时频域资源与这个R x,y候选资源在时频域上有重合，且该SCI对应的物理边链路共享信道(PSSCH，Physical Sidelink Shared Channel)的参考信号接收功率(RSRP，Reference Signal Receiving Power)的检测结果大于一个门限值(以下称为RSRP门限值)；或者，该SCI预留了选择窗之后的子帧，且该子帧与当前选择窗内子帧可能预留的后续子帧中的一个子帧在时域是同一个子帧，且频域资源与该R x,y候选资源在频域上有重合，且该SCI对应的PSSCH的RSRP的检测结果大于RSRP门限值Th(p t,p r)。
其中，RSRP门限值Th(p t,p r)中p t是终端设备要进行的边链路发送的优先级。p r是终端设备接收到的SCI指示的优先级，(p t,p r)与一个门限值Th(p t,p r)相关联。
步骤2-MAC层在候选资源集合中选择资源：
即终端设备的物理层可以将Set B上报给MAC层，MAC层在Set B中进行随机选择，选择一个候选资源进行数据发送。此外，选择一个解调和编码方案(MCS，Modulation and Coding Scheme)在选择的资源上进行数据发送。
在不产生歧义的条件下，本申请实施例可以不加区分地使用“排除”、“不选择”、“不包括”和“避开”。
正如前述发明内容部分所述，目前还没有提出如何确定辅助信息内感知的资源集合的方法，针对上述技术问题，本申请实施例提供相应的解决方案。即本申请实施例提供一种信息发送方案，即终端设备在确定辅助信息内的资源集合时，可以参考前述感知过程中排除Set A中的部分候选资源的方法，即通过sensing的方式确定该资源集合，与前述方法不同的是，不使用终端设备待发送数据的优先级，而根据使用辅助信息确定发送数据资源的对端终端设备发送该数据的优先级来确定辅助信息内感知的资源集合，由此，能够考虑对端终端设备发送的业务来确定辅助信息内感知的资源集合，以便该辅助信息能够更有效的辅助对端终端设备发送业务，以下结合第一方面的实施例进行说明。
第一方面的实施例
本申请实施例提供一种信息发送方法，从第二终端设备(以下为方面说明，简称为第二UE)侧进行说明；例如可以由该第二终端设备的物理层执行该信息发送方法，以下不再赘述。
图3是本申请实施例的信息发送方法的一示意图，如图3所示，该方法包括：
301，该第二UE根据第一发送优先级确定第二资源集合；
302，该第二UE将辅助信息发送给第一UE，该辅助信息包括该第二资源集合中资源的时频域信息，该第二资源集合用于该第一UE确定发送的第一边链路(SL)数据的第一候选资源集合，该第一发送优先级根据该第一UE发送该第一SL数据的优先级确定；
值得注意的是，以上附图3仅对本申请实施例进行了示意性说明，但本申请不限于此。例如可以适当地调整各个操作之间的执行顺序，此外还可以增加其他的一些操作或者减少其中的某些操作。本领域的技术人员可以根据上述内容进行适当地变型， 而不仅限于上述附图3的记载。
在一些实施例中，该第一SL数据是指第一SL数据包，上述该第一UE发送该第一SL数据包中的发送包括初传或重传，第一UE发送第一SL数据的优先级即表示发送该第一SL数据的PSSCH的优先级，该优先级由与该PSSCH相关的PSCCH上的SCI指示，优先级的值越高表示优先级越低反之亦可，例如，该优先级的值可以用0,1,2等表示，优先级是0表示优先级最高，但本实施例并不以此作为限制。
在一些实施例中，该第一SL数据可以是该第一UE发送给第二UE，也可以发送给其他UE，本实施例并不以此作为限制。
在一些实施例中，该第一发送优先级根据该第一UE发送该第一SL数据的优先级确定表示该第一发送优先级至少根据该第一UE发送该第一SL数据的优先级确定，即可以仅根据该第一UE发送该第一SL数据的优先级确定，也可以根据该第一UE发送该第一SL数据的优先级以及接收并使用该辅助信息的其他UE发送SL数据的优先级确定。
在一些实施例中，在该第二UE将辅助信息发送给第一UE，该第一UE使用或参考该辅助信息中的第二资源集合确定发送该第一SL数据的第一候选资源集合时，该第一发送优先级等于该第一SL数据的发送优先级。
在一些实施例中，该第二UE可以不仅向第一UE发送辅助信息，还可以向其他UE发送辅助信息，且其他UE也使用或参考该辅助信息中的第二资源集合确定发送其各自SL数据的候选资源集合(以下简称为UE使用/参考该辅助信息)，即使用或参考该辅助信息的UE多于一个，该第一发送优先级根据该第一SL数据的发送优先级和其他UE各自的SL数据的发送优先级确定，例如该第一发送优先级等于该第一SL数据的发送优先级和其他UE各自的SL数据的发送优先级中的最高优先级。
在一些实施例中，该方法还包括：(未图示，可选)
该第二UE将该辅助信息发送给第三UE，该第二资源集合还用于该第三UE确定发送的第三SL数据的第三候选资源集合；该第一发送优先级等于该第一SL数据的发送优先级和该第三SL数据的发送优先级中的最高优先级。例如，UE1发送第一SL数据的优先级是2，UE3发送第三SL数据的优先级是3，那么该第一发送优先级为2。
在一些实施例中，该方法还可以包括：该第二UE将该辅助信息发送给第四UE， 第五UE等，以此类推，该第一发送优先级等于接收并使用/参考该辅助信息的UE各自的SL数据的发送优先级中的最高优先级，本实施例不再一一赘述。
在一些实施例中，该方法还可以包括：(可选，未图示)
该第二UE接收该第一UE发送的第一SCI，该第一SCI用于指示该第一UE发送该第一SL数据的优先级。
在一些实施例中，第一UE发送该第一SL数据的优先级可以在第一SL数据的首次发送(初传)之前通过第一SCI进行指示，也可以在第一SL数据的首次发送(初传)之后通过第一SCI进行指示。
例如，该第一SCI可以是现有的格式也可以是新定义的格式，例如通过该第一SCI中的优先级指示域(信息元表示为priority)来指示该第一UE发送该第一SL数据的优先级。
在一些实施例中，该第一SCI还可以用于触发该辅助信息的发送，例如通过该第一SCI中的一个触发域来触发该辅助信息的发送。
在一些实施例中，该第二UE通过感知检测确定该第二资源集合，例如在感知检测的过程中根据第一发送优先级和第三接收优先级确定第二资源集合，具体的，第二UE根据第一发送优先级和第三接收优先级确定指示该第三接收优先级的第二SCI指示的全部或部分PSSCH资源是否包含在该第二资源集合中，第二UE会检测到一个或多个第二SCI，针对该一个或多个第二SCI，根据第一发送优先级和各个第二SCI指示的第三接收优先级分别确定各个第二SCI指示的全部或部分PSSCH资源是否包含在该第二资源集合中。
图4是该操作301实施一示意图，如图4所示，操作301包括：
401，该第二UE检测第二SCI，并对该第二SCI对应的PSCCH或PSSCH对应的参考信号进行测量，得到RSRP测量结果；
在一些实施例中，该第二UE在第一时间段内进行盲检(或监听)，以检测第二SCI，该第一时间段相当于感知窗，例如，可以检测到(接收到)一个或多个第二SCI，该第二UE可以对接收到的全部或者部分第二SCI对应的PSCCH或PSSCH对应的参考信号进行RSRP测量，在一些实施例中，RSRP可以通过对PSCCH(第二SCI)的解调参考信号(DM-RS)的测量获得，也可以通过对第二SCI调度的PSSCH的DM-RS的测量获得。该关于具体如何进行监听和测量，可以参考相关技术。
在一些实施例中，该第二SCI可以是上述第一UE发送的SCI(例如上述第一SCI)，和/或其他UE发送的SCI，本实施例并不以此作为限制。
402，该第二UE确定RSRP门限，其中，根据该第一发送优先级和检测到的第二SCI中指示的第三接收优先级确定该RSRP门限；
在一些实施例中，例如，每个测量的RSRP对应一个RSRP门限值Th(p t,p r)。p t是该第一发送优先级，而不是高层指示的第二UE自身待发边链路数据的发送优先级。p r是终端设备接收到的第二SCI指示的第三接收优先级。(p t,p r)与一个门限值Th(p t,p r)相对应，该对应关系可以由网络侧配置或预配置或预定义，具体可以参考相关技术。
403，将该RSRP测量结果与该RSRP门限进行比较，在检测到第二SCI，且检测到的第二SCI对应的PSCCH或PSSCH对应的参考信号的测量结果大于该门限时，将检测到的第二SCI指示的全部或部分PSSCH资源包含在第二资源集合中，或者在检测到第二SCI，且检测到的第二SCI对应的PSCCH或PSSCH对应的参考信号的测量结果小于该门限时，将检测到的第二SCI指示的全部或部分PSSCH资源包含在第二资源集合中。
例如，该第二UE对检测到的一个第二SCI对应的PSCCH或PSSCH对应的参考信号进行测量，得到RSRP测量结果1，根据该第一发送优先级和该一个第二SCI指示的第三接收优先级确定该RSRP门限1，将该RSRP测量结果1与该RSRP门限1进行比较，在测量1结果大于该门限1时，将该一个第二SCI_1指示的全部或部分PSSCH资源包含在第二资源集合中；该第二UE对检测到的另一个第二SCI对应的PSCCH或PSSCH对应的参考信号进行测量，得到RSRP测量结果2，根据该第一发送优先级和该另一个第二SCI指示的第三接收优先级确定该RSRP门限2，将该RSRP测量结果2与该RSRP门限2进行比较，在测量2结果大于该门限2时，将该另一个第二SCI指示的全部或部分PSSCH资源包含在第二资源集合中，以上以两个第二SCI举例说明，针对一个或者两个以上的情况处理方式类似，此处不再一一赘述。
在一些实施例中，如果测量结果小于门限，表示指示第三接收优先级的第二SCI指示的全部或部分PSSCH资源是推荐的资源，即第一UE在确定第一候选资源集合时可以考虑的资源，该第二资源集合为推荐资源集合，如果测量结果大于门限，表示指示第三接收优先级的第二SCI指示的全部或部分PSSCH资源是不推荐的资源(可 能是被占用的资源)，即第一UE在确定第一候选资源集合时需要排除的资源，该第二资源集合为排除资源集合。
在一些实施例中，该第二SCI指示的资源包括与当前SCI所在时间单元相同的PSSCH资源，和/或预留的重传对应的PSSCH资源和/或预留的用于发送下一个周期的PSSCH资源(应用于周期发送的场景)。
在一些实施例中，该辅助信息可以是周期发送或半持续发送或非周期发送，该第二UE接收到该第一SCI后，根据该第一SCI中的指示信息确定发送该辅助信息的资源，时延需求以及该辅助信息的发送优先级等参数，根据该参数发送该辅助信息。
在一些实施例中，该辅助信息的发送优先级可以是该第一发送优先级，该第一发送优先级可以由上述第一SCI指示，在获知该第一发送优先级后，即确定了该辅助信息的发送优先级，例如该第二UE可以发送辅助信息，其相关的PSCCH上的SCI中可以指示该辅助信息的发送优先级。
在一些实施例中，该方法还可以包括(可选，未图示)，该第二UE将该辅助信息发送给第四UE，由该第四UE将该辅助信息转发给该第一UE，具体在后述第七方面的实施例说明。
以上各个实施例仅对本申请实施例进行了示例性说明，但本申请不限于此，还可以在以上各个实施例的基础上进行适当的变型。例如，可以单独使用上述各个实施例，也可以将以上各个实施例中的一种或多种结合起来。
由上述实施例可知，终端设备不是根据该终端设备自身待发数据的优先级确定辅助信息内感知的资源集合，而是根据使用辅助信息确定发送数据资源的对端终端设备发送该数据的优先级来确定辅助信息内感知的资源集合，由此，能够考虑对端终端设备发送的业务来确定辅助信息内感知的资源集合，以便该辅助信息能够更有效的辅助对端终端设备发送业务。
第二方面的实施例
本申请实施例提供一种资源确定方法，从第一终端设备(以下为方便说明，简称为第一UE)侧进行说明，其中，与第一方面的实施例的重复部分不再赘述。
图5是本申请实施例的资源确定方法的一示意图，如图5所示，该方法包括：
501，该第一UE接收第二UE发送的辅助信息；其中，该辅助信息包括第二资源 集合中资源的时频域信息，该第二资源集合是该第二UE根据第一发送优先级确定的，该第一发送优先级根据该第一UE发送第一边链路数据的优先级确定；
502，该第一UE根据该第二资源集合确定发送该第一边链路数据的第一候选资源集合。
在一些实施例中，该辅助信息、该第二资源集合、该第一发送优先级、该第一SL数据的发送优先级具体实施方式可以参考第一方面的实施例，501与第一方面的实施例中301-302对应，重复之处不再赘述。
在一些实施例中，在该第二资源集合包含的是推荐资源时，该第一UE在确定第一候选资源集合可以考虑该第二资源集合中的资源，即第二资源集合中的资源可以作为第一候选资源，在该第二资源集合包含的是排除资源时，该第一UE在确定第一候选资源集合时不考虑该第二资源集合，即第二资源集合中的资源不会被作为第一候选资源。
在一些实施例中，该方法还可以包括：(可选，未图示)该第一UE从该第一候选资源集合中选择第一资源，并在该第一资源上发送该第一SL数据，具体可以参考相关技术，此处不再赘述。
在一些实施例中，该第一UE可以广播发送该第一SL数据，也可以组播发送该第一SL数据，也可以单播发送该第一SL数据，可以向第二UE发送该第一SL数据，也可以向其他UE发送该第一SL数据，本实施例并不以此作为限制。
由上述实施例可知，终端设备不是根据该终端设备自身待发数据的优先级确定辅助信息内感知的资源集合，而是根据使用辅助信息确定发送数据资源的对端终端设备发送该数据的优先级来确定辅助信息内感知的资源集合，由此，能够考虑对端终端设备发送的业务来确定辅助信息内感知的资源集合，以便该辅助信息能够更有效的辅助对端终端设备发送业务。
在LTE V2X以及NR V2X中，除了前述的资源感知检测过程中需要考虑当前UE自身待发数据优先级，在发送数据/信息的过程中也有一些处理需要考虑当前UE自身待发数据优先级，该处理包括但不限于确定发送数据/信息的资源，拥塞控制，功率控制以及确定该发送数据/信息的优先级等，本申请实施例还提供一种信息发送方案，即执行向对端终端设备发送辅助信息的处理时，不使用终端设备待发送的边链路的优 先级，而根据使用辅助信息确定发送数据资源的对端终端设备发送该数据的优先级来确定执行向对端终端设备发送辅助信息的处理，由此，能够考虑对端终端设备发送的业务来执行向对端终端设备发送辅助信息的处理，以便该辅助信息能够更有效的辅助对端终端设备发送业务，以下结合第三方面的实施例进行说明。
第三方面的实施例
本申请实施例提供一种信息发送方法，从第二终端设备(以下为方便说明，简称为第二UE)侧进行说明。
图6是本申请实施例的信息发送方法的一示意图，如图6所示，该方法包括：
601，该第二UE根据第一发送优先级执行与向该第一UE发送辅助信息相关的处理；其中，该辅助信息用于该第一UE确定发送的第一边链路数据的第一候选资源集合，该第一发送优先级根据该第一UE发送该第一边链路数据的优先级确定；
602，该第二UE根据处理结果向该第一UE发送该辅助信息，或者不发送该辅助信息，或者对该辅助信息的发送进行功率缩减。
值得注意的是，以上附图6仅对本申请实施例进行了示意性说明，但本申请不限于此。例如可以适当地调整各个操作之间的执行顺序，此外还可以增加其他的一些操作或者减少其中的某些操作。本领域的技术人员可以根据上述内容进行适当地变型，而不仅限于上述附图6的记载。
在一些实施例中，该辅助信息、该第一发送优先级、该第一SL数据的发送优先级具体实施方式可以参考第一方面的实施例，重复之处不再赘述。
在一些实施例中，该与发送辅助信息相关的处理包括但不限于确定发送该辅助信息的资源，发送该辅助信息时的拥塞控制，发送该辅助信息时的功率缩减以及确定发送该辅助信息的优先级，以下分别说明。
在一些实施例中，该处理是确定该辅助信息的发送优先级，在601-602中，根据该第一发送优先级确定该辅助信息的发送优先级，例如，确定该辅助信息的发送优先级是该第一发送优先级；并且，该第二UE按照该第一发送优先级向该第一UE发送该辅助信息。
在一些实施例中，该处理是确定发送该辅助信息的资源，包括确定第四候选资源集合以及从该第四候选资源集合中选择的发送该辅助信息的资源。其中，确定该资源 的过程可以参考感知检测+资源选择的过程，图7是确定资源方法示意图，如图7所示，该方法包括：
701，该第二UE检测第三SCI，并对该第三SCI对应的PSCCH或PSSCH对应的参考信号进行测量，得到RSRP测量结果；其处理可以参考第一方面的实施例中操作401，该第三SCI的含义与该第二SCI相同，此处不再赘述。
702，该第二UE确定RSRP门限，其中，根据该第一发送优先级或第二发送优先级和检测到的第三SCI中指示的第三接收优先级确定该RSRP门限；该第二发送优先级等于该第一发送优先级和该辅助信息的发送优先级中的最高优先级；
在一些实施例中，例如，每个测量的RSRP对应一个RSRP门限值Th(p t,p r)。p t是该第一发送优先级或第二发送优先级，而不是高层指示的第二UE自身待发边链路数据的发送优先级。p r是终端设备接收到的第三SCI指示的第四接收优先级。(p t,p r)与一个门限值Th(p t,p r)相对应，该对应关系可以由网络侧配置或预配置或预定义，具体可以参考相关技术。
703，将该RSRP测量结果与该RSRP门限进行比较，根据比较结果确定该第四候选资源集合；
在一些实施例中，该第二UE的物理层从高层(例如介质访问控制(MAC，Media Access Control)层)获得资源选择的粒度R x,y；该粒度含义可以参考现有技术；整个选择窗中的所有时间单元内R x,y大小的资源(以下简称为R x,y候选资源)的集合被初始化定义为Set A。该第二UE可以根据在发送该辅助信息之前在该感知窗内进行检测，排除Set A中的部分候选资源后得到该第四候选资源集合。例如，以下的R x,y候选资源需要被排除：终端设备在感知窗内进行检测的时间单元中的某个R x,y候选资源，其中在该R x,y候选资源上检测到指示该第三接收优先级的第三SCI预留了当前选择窗内对应的时间单元，且指示的频域资源与这个R x,y候选资源在频域上有重合，且RSRP测量结果大于RSRP门限，或者，该指示该第三接收优先级的第三SCI预留了选择窗之后的时间单元，且该时间单元与当前选择窗内时间单眼可能预留的后续时间单元中的一个时间单元在时域是同一个时间单元，且频域资源与该R x,y候选资源在频域上有重合，且该RSRP测量结果大于RSRP门限Th(p t,p r)。
704，终端设备的物理层可以将第四候选资源集合上报给MAC层，MAC层在第四候选资源集合中进行随机选择，选择一个候选资源进行该辅助信息的发送。
在一些实施例中，该基于终端设备的能力，确定发送该辅助信息的资源的时间为参数Tproc,1'，该参数值大于确定发送非辅助信息的资源的时间参数值Tproc,1，例如可以进行补偿，如Tproc,1'＝Tproc,1+X，X可以为1,2…，单位为时间单元，对于不同子载波间隔，X的取值可以不同，例如，子载波间隔越大，X越大。
在一些实施例中，该处理是发送该辅助信息时的拥塞控制，在601-602中，根据该第一发送优先级或第二发送优先级，以及当前测量得到的信道忙率值进行拥塞控制；其中，该第二发送优先级等于该第一发送优先级和该辅助信息的发送优先级中的最高优先级；并且，该第二UE根据拥塞控制的结果确定向该第一UE发送该辅助信息，或者不发送该辅助信息。图8是拥塞控制方法一示意图，如图8所示，该方法包括：
801，确定与该第一发送优先级或该第二发送优先级，以及当前测量得到的信道忙率值对应的信道占用率阈值；
在一些实施例中，该信道占用率阈值CR Limit(k)是查表获得的，例如预定义或预配置优先级与至少一个第一表的对应关系，从至少一个第一表中确定与该第一发送优先级或该第二发送优先级k对应的第一映射表；根据当前测量得到的信道忙率值CBR和该第一映射表确定信道占用率阈值。该第一映射表包括优先级，CBR以及信道占用率阈值的对应关系，根据该第一/第二发送优先级以及计算得到的CBR，确定信道占用率阈值，该CBR是预定时间段内检测到的子信道中接收信号强度指示大于RSRP阈值(高层配置或预配置的)的子信道占所有子信道的比值。
802，根据该信道占用率阈值进行拥塞控制；
在一些实施例中，该第二UE在发送该辅助信息时，考虑该辅助信息的发送优先级需要保证该辅助信息的发送能够满足信道占用率的限制，即满足如下公式(1)：
Figure PCTCN2020107551-appb-000001
其中，该CR(i)表示预定时间段内对应优先级i的业务占用的子信道的数量与配置的子信道数量的比值。如果满足该公式(1)，那么可以发送该辅助信息，如果不满足该公式(1)，在当前时间单元，可以将该辅助信息对应的数据包丢弃而不发送。
在一些实施例中，该方法还可以包括：
803(可选)，该第二UE接收资源池配置信息，该资源池配置信息包括第二指示信息，该第二指示信息用于指示是否发送辅助信息；
并且，在602中，该第二UE根据该拥塞控制的结果和该第二指示信息确定向该第一UE发送该辅助信息，或者不发送该辅助信息。在拥塞控制和第二指示信息均确定发送该辅助信息时，发送该辅助信息，在该拥塞控制和该第二指示信息中至少一个确定不发送该辅助信息时，不发送该辅助信息。
图9是拥塞控制方法一示意图，如图9所示，该方法包括：
901，从至少一个第二表中确定与该第一发送优先级或该第二发送优先级对应的第二映射表；
在一些实施例中，预定义或预配置至少一个第二表和优先级的对应关系，根据该第一/二发送优先级确定该第二映射表，该第二映射表中包括不同CBR与第一指示信息的对应关系，例如针对第一CBR范围，其指示发送该辅助信息ON，针对第二CBR范围，其指示不发送辅助信息OFF。
902，根据当前测量得到的信道忙率值和该第二映射表确定指示是否发送该辅助信息的第一指示信息。
在一些实施例中，可以根据当前测量得到的CBR查找第二映射表确定是否发送辅助信息，如果对应的第一指示信息是ON，则发送该辅助信息，否则不发送该辅助信息，可选的，如果对应的第一指示信息是OFF，该第二UE可以忽略该第一UE发送的第一SCI。
在一些实施例中，该处理是丢弃该辅助信息或发送该辅助信息时的功率缩减，在步骤601-602中，在该辅助信息的发送或与该辅助信息相关的信息的发送与其他信息的发送或接收在时间上重叠时，根据该第一发送优先级或该第二发送优先级与该其他信息的发送或接收优先级的比较结果确定是否丢弃该辅助信息和/或与该辅助信息相关的信息，或确定是否对该辅助信息和/或与该辅助信息相关的信息的发送进行功率缩减，其中，该第二发送优先级等于该第一发送优先级和该辅助信息的发送优先级中的最高优先级。例如，在该第一/第二发送优先级低于其他信息的发送优先级时，丢弃该辅助信息，或者缩减该辅助信息的发送功率。在一些实施例中，该辅助信息的发送或与该辅助信息相关的信息的发送包括：该辅助信息的PSSCH的发送，承载对应该辅助信息的反馈信息的PSFCH的发送，以及承载对应该辅助信息的所馈信息的PUCCH的发送中的至少一个；该其他信息的发送或接收包括：使用LTE无线接入的SL发送或接收，上行数据的发送，承载其他反馈信息的PSFCH的发送或接收中的至 少一个。
例如，在使用NR无线接入的该辅助信息的发送或与该辅助信息相关的信息的发送与在使用LTE无线接入的SL发送或接收在时间上重叠时，发送或接收优先级高的。例如，在该第一/第二发送优先级高于使用LTE无线接入的SL的发送或接收优先级时，进行辅助信息的发送或与该辅助信息相关的信息的发送。
例如，该辅助信息的PSSCH的发送与其他上行数据的发送重叠，则发送优先级高的，丢弃另一个(支持同时发送上行UL和SL)，或者发送优先级高的，并减少优先级低的发送功率(不支持同时发送上行UL和SL)，使得总发送功率不超过最大功率要求，具体是丢弃还是功率缩减可以根据UE的能力而定，本申请并不以此作为限制。
例如，承载对应该辅助信息的反馈信息的PSFCH的发送与其他上行数据的发送重叠时，还需要判断对应的PUCCH或PUSCH是否配置的优先级1，以及PSFCH中对应的优先级最高的PSSCH的对应优先级是否高于阈值，根据判断结果确定发送该PSFCH还是发送其他上行数据。
例如，承载对应该辅助信息的反馈信息的PSFCH的发送与其他PSFCH的接收重叠，则选择优先级高的PSFCH发送或接收。例如，在该第一/第二发送优先级高于其他PSFCH的优先级时，发送该PSFCH。
例如，承载对应该辅助信息的反馈信息的PSFCH的发送与其他PSFCH的发送重叠，则在功率受限(即所有PSFCH的发送功率和大于终端设备的最大发送功率)时，选择优先级高的N(大于等于2)个PSFCH发送。例如，在该第一/第二发送优先级高于其他PSFCH的优先级时，发送该辅助信息，在该第一/第二发送优先级低于其他N个PCFCH的发送优先级时，丢弃该辅助信息。
例如，承载对应该辅助信息的反馈信息的PUCCH的发送与其他边链路数据的发送重叠，发送优先级高的，丢弃另一个。
上述重叠的场景不再一一举例，具体可以参考3GPP标准TS38.2.1.3章节16.2.4。
由上述实施例可知，执行向对端终端设备发送辅助信息的处理时，不使用终端设备待发送的边链路的优先级，而根据使用辅助信息确定发送数据资源的对端终端设备发送该数据的优先级来确定执行向对端终端设备发送辅助信息的处理，由此，能够考虑对端终端设备发送的业务来执行向对端终端设备发送辅助信息的处理，以便该辅助 信息能够更有效的辅助对端终端设备发送业务。

第七方面的实施例
本申请实施例提供一种信息发送方法，从第四终端设备(以下为方便说明，简称为第四UE)侧进行说明。由于链路信道状况不好，或第一UE正在发送(由于边链路UE是半双工的，产生了发送和和接收冲突)的原因，第一UE没有接收到第二UE发送的辅助信息，因此，为了提高可靠性，可以借助第四UE转发该辅助信息，即该第二UE还可以将该辅助信息发送给第四UE，由第四UE将该辅助信息转发给第一UE。
