技术领域
本申请涉及通信技术领域，尤其涉及一种资源确定方法及装置。
背景技术
目前的移动通信技术，例如侧行链路通信(sidelink)场景，支持终端设备(UE)对周边其他终端设备进行感知。进行感知的UE能够接收附近的其他UE传输的数据，以便根据接收的数据获知附近的UE所采用的资源，能够避免在感知到有数据传输的资源上进行侧链路(sidelink，SL)数据传输(或称侧行传输)传输，以降低进行SL传输时说道的干扰。其中，感知的目的之一，是获知周边其他UE对于传输资源的预约情况，以便合理选择自身通过SL传输数据所采用的传输资源。
当传输资源由多个业务预约时，UE无法合理判断是否在该传输资源上进行数据的传输，需要优化。
发明内容
本申请提供一种资源确定方法及装置，以满足不同类型的UE对于侧行传输的要求。
第一方面，本申请实施例提供一种资源确定方法，该方法可以由支持侧行传输的终端设备或终端设备中的部件(比如处理器、芯片或芯片***等)执行。
下面以执行主体为终端设备为例进行描述。根据该方法，终端设备可获取多个第二终端设备的至少N个业务的资源信息。其中，该资源信息可包括第一资源的信息，第一资源为N个业务共同预约的资源，N大于或等于2。终端设备还可根据第一资源的信息确定N个业务分别的信号强度门限，以及根据接收N个业务分别的资源信息的信号强度确定N个业务分别的信号强度。当N个业务分别的信号强度门限以及N个业务分别的信号强度满足第一条件时，终端设备可确定待选资源集合包括第一资源。
采用以上方法，可由终端设备根据N个业务分别的信号强度门限以及N个业务分别的信号强度合理确定是否将N个业务沟通预约的第一资源作为待选资源，供终端设备考虑选择待选资源作为侧行传输资源，从而终端设备能够根据待选资源选择干扰较低的资源进行侧行传输，降低侧行传输中受到的干扰，因此提高了侧行传输性能。
在一种可能的设计中，第一资源的信息包括N个业务的优先级信息、第一资源的索引、第一资源的时频位置信息、N个业务的类型信息中的至少一个。其中，N个业务的优先级信息可用于终端设备确定N个业务分别的信号强度门限。第一资源的索引以及第一资源的 时频位置信息用于终端设备通过第一资源进行数据传输。N个业务的类型信息可用于终端设备确定N个业务分别的类型，以识别N各业务是否为周期性业务或非周期性业务。
在一种可能的设计中，第一资源的信息包括N个业务的优先级信息，终端设备可根据N个业务的优先级信息确定N个业务分别的信号强度门限，以提高信号强度门限的确定效率。
在一种可能的设计中，终端设备可根据N个业务分别的信号强度门限确定第一信号强度门限，其中，第一信号强度门限包括N个业务中优先级最高的业务的信号强度门限、N个业务中业务的信号强度门限与信号强度的差值最小的业务的信号强度门限，或者m个业务分别的信号强度门限中最小的信号强度门限，其中，m个业务为N个业务中的部分或全部业务，m为正整数，且m小于等于N。采用该设计，可实现更为灵活的第一信号强度门限的确定方式。

在一种可能的设计中，该第一信号强度根据该N个业务中优先级最高的业务的信号强度确定；或者，该第一信号强度根据该N个业务中信号强度门限最小的业务的信号强度确定；或者，该第一信号强度根据该m个业务中信号强度门限与信号强度的差值最小的业务的信号强度确定，该m个业务为该N个业务中的部分或全部业务，m为正整数，且m小于等于N；或者，该第一信号强度根据m个业务分别的信号强度中最大的信号强度确定；或者，该第一信号强度为该m个业务分别的信号强度的总和。采用该设计，可实现更为灵活的第一信号强度的确定方式。
在一种可能的设计中，第一条件包括第一信号强度门限大于或等于第一信号强度。因此，根据第一信号门限强度和第一信号强度灵活确定是否将第一资源作为待选资源。
在一种可能的设计中，终端设备还可根据该N个业务中优先级最高的周期性业务的优先级和优先级最高的非周期性业务的优先级，从该优先级最高的周期性业务与该优先级最高的非周期性业务中确定该优先级最高的业务。采用该设计，可根据优先级最高的周期性业务和/或优先级最高的非周期性业务实现更为合理的资源确定方式。
在一种可能的设计中，该m个业务包括该N个业务中优先级最高的周期性业务和/或该N个业务中优先级最高的非周期性业务。采用该设计，可根据优先级最高的周期性业务和/或优先级最高的非周期性业务实现更为合理的资源确定方式。

具体实施方式
本申请提供一种资源确定方法以优化传输资源确定方式。下面将结合附图对本申请作进一步地详细描述。应理解，下面所介绍的方法实施例中的具体操作方法也可以应用于装置实施例或***实施例中。
本申请实施例提供的资源确定方法可应用于图1A所示无线通信***100。应理解，无线通信***100可包括至少一个终端设备，图1A中以手机为例示出终端设备可能的形态，但不应理解为终端设备仅以手机为限。
终端设备可以是固定位置的，也可以是可移动的。应理解，图1A只是一种无线通信***架构的示意图，本申请提供的通信***中还可以包括图1A中未示出的其它网络设备，如还可以包括接入网设备、无线中继设备和无线回传设备等。本申请的实施例对该移动通信***中包括的核心网设备、无线接入网设备和终端设备的数量不做限定。
其中，终端设备具体可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字处理(personal digital assistant，PDA)设备、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、无人驾驶车辆、可穿戴设备、未来5G网络中的终端装置或者未来演进的PLMN网络中的终端装置等。终端设备可以部署在陆地上，包括部署于室内或室外、由用户手持或由车载；终端设备也可以部署在水面上(如轮船等)；终端设备还可以部署在空中(例如飞机、气球和卫星上等)。
示例性的，终端设备可以是终端(terminal)、移动台(mobile station，MS)、移动终端(mobile terminal)等设备，或芯片、芯片***等装置。终端设备能够与一个或多个通信***的一个或多个网络设备进行通信，并接受网络设备提供的网络服务，这里的网络设备包 括但不限于图示第三通信装置。举例来说，本申请实施例中的终端设备可以是手机(mobile phone)、平板电脑(pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端、增强现实(augmented reality，AR)终端、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等，终端设备还可以是便携式、袖珍式、手持式、计算机内置的或者车载上的移动装置。终端设备也可以是具有通信模块的通信芯片。
应理解，以上无线通信***100既可适用于低频场景(sub 6G)，也可适用于高频场景(above6G)。无线通信***100的应用场景包括但不限于通用移动通信***(universal mobile telecommunications system，UMTS)长期演进(long term evolution，LTE)***第五代(5th generation，5G)移动通信***中的新无线(new radio，NR)***以及未来的移动通信***等。
此外，该无线通信***100所包括的至少一个终端设备可以是车载设备或其他车联网通讯设备。例如图1B所示，车载设备UE-A可位于UE-B以及UE-C的覆盖范围内，因此UE-A可接收来自于UE-B以及UE-C的数据。另外，本申请并不限制UE-A可位于UE-B以及UE-C以外的其他UE的覆盖范围内。
应理解，图1A和图1B所示的终端设备可被配置为支持与包括基站在内的网络设备通过通用用户和网络的空口(universal user to network interface，Uu空口)进行通信。以上终端设备还可被配置为支持侧行传输，例如，图1A所示的UE-A可与UE-B和/或UE-C通过直接通信(PC5)空口进行SL通信。应理解，终端设备可以是具有通信模块或可连接至通信模块的芯片，如车载设备中的芯片或模块。或者其他嵌入式模块。示例性的，终端设备例如车终端(vehicle user/vehicle UE，VUE)以及易受伤路边设备(vulnerable road user/unit，VRU)等类型，其中，VRU可包括人终端(person user/person UE，PUE)以及路侧单元(road side unit，RSU)、智能路灯等等。
应理解，基于图1A或图1B所示通信***100，可应用于不同时延要求和可靠性要求的业务场景，比如，可应用于UE-A通过侧行传输发送服务或业务数据的场景：低时延要求和高可靠性要求的自动驾驶服务、地理位置服务、地图服务等场景，或应用于低时延要求和低可靠性要求的语音服务，或应用于低可靠行要求的在线游戏服务，或高可靠性要求的数据共享服务等业务。
下面以图1A或图1B所示的UA-A向UE-B、UE-C或UE-B和UE-C以外的其他UE发送业务数据为例，对本申请进行说明。其中，UE-A为车辆A的车载设备，或者，UE-A也可以是用户的手机等智能终端，对此不予具体限定。
当UE-A需要向其他UE通过侧行传输发送数据时，UE-A可从资源池中选择传输资源(或称资源)，其中，资源池可由UE-A接入的网络设备配置，例如，网络设备可以是(base station，BS)，或包括基站以及用于控制基站的无线资源管理设备等。这里的基站，可以是UMTS/LTE***中的演进型基站(evolutional nodeB，eNB或eNodeB)、异构网络(heterogeneous network，HetNet)场景下的微基站B，分布式基站场景下的基带处理单元(base band unit，BBU)和/或射频单元(remote radio unit,RRU)，也可以是小基站(micro/picoeNB)或传输接收节点(transmission/reception point，TRP)还可以是云无线接 入网络(cloud radio access network，CRAN)场景下的无线控制器、基带池(BBU pool)和/或RRU。或者该第三通信装置可以为中继站、接入点、可穿戴设备以及未来5G网络中的基站或者未来演进的PLMN网络中的基站等，例如，新一代节点B(generated node B，gNB)，本申请实施例并不限定。第三通信装置也可以是具有通信模块或可连接至通信模块的芯片，如基站中的芯片。
以网络设备为gNB为例，应理解，图1A或图1B所示的UE-A可位于gNB的覆盖范围内，且UE-B和/或UE-C可位于gNB的覆盖范围内。当UE-A通过侧行传输向其他UE传输数据时，该其他UE可位于gNB的覆盖范围内，也可位于该gNB的覆盖范围外。
按照目前已有的资源确定方法，UE-A可根据以下方法选择侧行传输采用的资源：
步骤1，UE-A接收周边一个或多个其他UE(包括但不限于图1A或图1B所示UE-B及UE-C)发送的数据，该数据可用于确定预约某个传输资源的业务和/或业务的优先级信息。
应理解，本申请中，当UE-A通过某个资源接收到正在传输的业务数据时，可称业务占用该传输资源(如传输资源B)，对于周期性业务，业务数据还会预约该传输资源之后的与该传输资源之间时域间隔为传输周期(gap)的传输资源(如传输资源A，传输资源A与传输资源B之间的时域间隔为gap)。或者，来自于其他UE的数据可包括资源信息，当UE-A获取资源信息，表示业务数据在将来的某传输资源(如传输资源A)上传输，则可称业务预约该传输资源，此时也可称该业务预约(reservation)该传输资源。
步骤2，UE-A根据传输资源A上预约的业务的优先级信息(以下称为第一优先级信息)以及UE-A需要发送的业务的优先级信息(以下称为第二优先级信息)，确定该传输资源A对应的信号强度门限，其中，该信号强度门限与第一优先级信息以及第二优先级信息三者之间存在对应关系。
示例性的，传输资源对应的信号强度门限可表示为SL-ThresRSRP_pi_pj，其中，pi是预约该传输资源的业务的优先级信息，pj是UE-A需要发送的业务的优先级信息。
如表1所示，为SL-ThresRSRP_pi_pj、pi和pj三者之间的对应关系表。其中，可认为pi取值越高，表示UE-A需要发送的业务的优先级越高，同理，pj取值越高，表示预约该传输资源的业务的优先级越高。这里以pi和pj的取值与业务的优先级成正比为例进行说明，也不排除pi和pj的取值与业务的优先级成反比，比如，pi取值越高，表示UE-A需要发送的业务的优先级越低，同理，pj取值越高，表示预约该传输资源的业务的优先级越低。
SL-ThresRSRP_pi_pj(/dBm) pi pj
门限1 1 1
门限2 1 2
门限3 2 1
表1
表1中，若pi不变，pj取值越大，则pi以及pj对应的SL-ThresRSRP_pi_pj取值越小。比如，表1中门限1与门限2对应的pi取值均为1，但门限1对应的pj取值小于门限2对应的pj取值，则门限1的取值大于门限2的取值，例如，门限1的取值为15分贝毫瓦(dBm)，门限2的取值为10dBm。若pj不变，pi取值越大，则对应的SL-ThresRSRP_pi_pj取值越大。比如，表1中门限1与门限3对应的pj取值均为1，但门限3对应的pi取值大于门限1对应的pi取值，则门限3的取值大于门限1的取值，例如，门限1的取值为15dBm，门 限3的取值为20dBm。
应理解，表1所示的对应关系表可预先存储在UE-A中，或者可由基站等网络设备发送至UE-A。此外，对于不同的传输资源，SL-ThresRSRP_pi_pj、pi、以及pj之间的对应关系可以相同，例如均如表1所示。
同理，UE-A还可基于以上方式确定其他传输资源对应的SL-ThresRSRP_pi_pj。
步骤3，UE-A可根据传输资源A上的接收信号的信号强度和该传输资源A对应的信号强度门限确定是否将该传输资源A作为待选资源。其中，该传输资源A上的接收信号的信号强度可由UE-A对该传输资源A进行感知获得，该信号强度越大，表示UE-A在该传输资源A上进行侧行传输时受到的干扰越强。
示例性的，UE-A可对传输资源A进行感知，获得参考信号接收功率(reference signal receiving power，RSRP)，RSRP即该传输资源A上的接收信号的信号强度。此后，UE-A可比较RSRP与该传输资源A对应的信号强度门限的大小。例如，UE-A根据pi以及pj确定该传输资源A对应的信号强度门限为表1所示的门限1，则UE-A可根据该RSRP与门限A进行比较，若RSRP不大于(或小于)门限1，则UE-A确定该传输资源A属于待选资源；若RSRP不小于(或大于)门限1，则UE-A确定该传输资源A不属于待选资源。
同理，UE-A还可基于以上方式确定其他传输资源是否属于待选资源。
步骤4，当UE-A确定了至少一个待选资源(该至少一个待选资源的集合可称为待选资源集合)时，UE-A可从至少一个待选资源中，根据待选资源的信号强度等因素确定用于发送业务数据的传输资源，该传输资源可用于UE-A发送业务数据，如用于UE-A通过SL通信向其他UE发送业务数据。其中，接收UE-A发送的业务数据的UE可以不同于发送资源信息的任何一个UE，或者，也可以是发送资源信息的一个或多个UE，例如，包括但不限于图1A或图1B所示UE-B及UE-C。
示例性的，UE-A可根据待选资源分别的RSRP的大小，选择RSRP最小的待选资源用于发送业务数据，以降低业务数据的发送过程受到的传输干扰。
基于以上资源确定方式，如果UE-A发现预约传输某个资源的业务的数量为多个，且多个业务分别的优先级不同，那么UE-A在根据表1所示对应关系确定该传输资源的SL-ThresRSRP_pi_pj时将会出现困难，因为pi的取值会有多个，UE-A很有可能无法合理确定SL-ThresRSRP_pi_pj，也就不能准确判断该传输资源是否属于待选资源。此外，如果存在多个业务均预约该传输资源的情况，即便多个业务的优先级相同，也就是多个业务的SL-ThresRSRP_pi_pj均相同，但UE-A感知的每个业务数据的RSRP极大可能是不同的，因此UE-A很有可能无法合理选择一个RSRP，用于比较RSRP与SL-ThresRSRP_pi_pj的大小，仍然无法合理判断该传输资源是否属于待选资源。因此，有需要对现有SL通信中的资源确定方式进行优化。
本申请实施例提供的一种资源确定方法，可以用于图1A或图1B所示通信***，以提高UE-A在发送侧行传输数据时资源确定的合理性，提高传输性能。示例性的，该方法可包括图2所示的以下步骤：
S101：UE-A获取多个第二UE的至少N个业务的资源信息。
该资源信息包括第一资源的信息，该第一资源为N个业务共同预约的资源，N大于或等于2。其中，该第一资源为多个UE预约的资源，因此多个第二UE可通过该第一资源发送相应业务的数据或接收相应业务的数据。
应理解，这里的业务可以是第二UE进行的侧行传输业务。具体的，侧行传输业务可包括周期性业务或非周期性业务。该多个第二UE可包括图1A或图1B所示的UE-B、UE-C或者图1A及图1B中未示出的其他UE中的至少一个UE。
在一种可能的实现方式中，该资源信息可包括来自于多个第二UE的业务以及该业务预约的资源的信息之间的对应关系。UE-A可通过感知接收来自于第二UE的以上对应关系。
其中，业务预约的资源的信息可包括预约该资源的业务的优先级信息、该资源的索引、该资源的时频位置信息或该业务的业务类型信息中的至少一个。该预约该资源的业务的优先级信息可用于UE-A确定该业务的信号强度门限。UE-A在确定该资源作为待选资源后，可根据该资源的索引以及该资源的时频位置信息通过该资源进行侧行传输。该业务的业务类型信息可用于确定该业务的类型，比如，类型信息可指示业务为自动驾驶服务、地理位置服务、地图服务、语音服务等业务类型的业务，因此UE-A可根据业务类型确定该业务是周期性业务还是非周期性业务。此外，业务预约的资源的信息还可包括第二UE的通信标识，用于标识业务所属的第二UE和发送该业务的资源信息的第二UE。
当UE-A接收来自于多个第二UE的资源信息后，可获取业务及业务的优先级信息与业务预约的资源的信息之间的对应关系表，用于确定该对应关系表中的传输资源是否作为待选资源。
示例性的，UE-A接收的来自于UE-B的多个业务的资源信息例如表2所示，其中，UE-B的业务1、业务3以及业务5分别预约资源A、资源B以及资源C。应理解，表2中以业务预约的资源的信息包括业务的优先级信息以及传输资源的索引为例进行说明，不能以资源信息为表2优先级信息以及传输资源的索引为限。
业务 业务的优先级信息 资源的索引
业务1 1 资源A
业务3 2 资源B
业务5 3 资源C
…… …… ……
表2
此外，UE-A接收的来自于UE-C的多个业务的资源信息例如表3所示，其中，UE-C的业务2、业务4以及业务6分别预约资源A、资源B以及资源C。
业务 业务的优先级信息 资源的索引
业务2 2 资源A
业务4 3 资源B
业务6 3 资源C
…… …… ……
表3
在接收如表2和表3所示的资源信息后，UE-A可确定表4所示的多个业务预约的资源的信息与业务之间的对应关系，根据表4所示的对应关系可识别N个业务预约的第一资源。其中，与表2及表3相比，在表4中每个资源的信息对应于多个业务。
资源的索引 业务
资源A 业务1，业务2
资源B 业务3，业务4
资源C 业务5，业务6
…… ……
表4
表4中以资源的信息为资源的索引为例进行说明，基于表4，UE-A可确定资源A、资源B以及资源C分别由多个业务预约，因此可确定第一资源包括资源A、资源B以及资源C，UE-A可根据本申请提供的方法分别识别资源A、资源B以及资源C是否作为待选资源。第一资源的信息可包括预约第一资源的N个业务的优先级信息、第一资源的索引、第一资源的时频位置信息或该N个业务的业务类型信息。此外，第一资源的信息还可包括第二UE的通信标识，用于标识预约第一资源的业务所属的第二UE和发送该业务的资源信息的第二UE。
以第一资源为资源A为例，第一资源的信息可包括业务1以及业务2的优先级信息及业务类型信息，以及包括资源A的索引和资源A的时频位置信息。
应理解，表4以资源的索引为例进行说明资源的信息与业务之间的对应关系，资源的信息还可包括预约该资源的业务的优先级信息、该资源的索引、该资源的时频位置信息或该业务的业务类型信息中的至少一个。
S102：UE-A根据该资源信息的信息确定预约第一资源的N个业务分别的信号强度门限。
示例性的，预约该第一资源的业务的信号强度门限可根据UE-A需要发送的业务的优先级pj、该业务的优先级pi以及pi、pj和信号强度门限SL-ThresRSRP_pi_pj之间的对应关系确定该业务的信号强度门限，其中，该业务的优先级可携带在第一资源的信息中，UE-A需要发送的业务的优先级由UE-A根据该业务确定，pi、pj和信号强度门限SL-ThresRSRP_pi_pj之间的对应关系例如表1所示。
具体的，若N个业务包括业务1，且业务1的优先级为1(即pj＝1)，若UE-A将要进行的SL业务的优先级为1(即pi＝1)，则根据表1，UE-A可确定业务1的信号强度门限为门限1。
S103：UE-A根据接收N个业务分别的资源信息的信号强度，确定N个业务分别的信号强度。
比如，若N个业务包括业务1以及业务2，其中，业务1为UE-B的业务，业务2为UE-C的业务，UE接收来自于UE-B的包含业务1的资源信息时获得的RSRP为RSRP1，UE接收来自于UE-B的包含业务2的资源信息时获得的RSRP为RSRP2，则UE-A可将RSRP1作为该业务1的信号强度，或根据现有方法对RSRP1进行处理以获得业务1的信号强度，以及，可根据将RSRP2作为该业务2的信号强度，或根据现有方法对RSRP2进行处理以获得业务2的信号强度。
示例性的，根据S102和S103所示步骤，UE-A可针对预约该第一资源的N个业务，确定每个业务的信号强度门限和信号强度。其中，预约该第一资源的业务的信号强度门限可根据UE-A需要发送的业务的优先级pj、该业务的优先级pi以及pi、pj和信号强度门限SL-ThresRSRP_pi_pj之间的对应关系确定该业务的信号强度门限。具体的，pi、pj和信号强度门限SL-ThresRSRP_pi_pj之间的对应关系例如表1所示。预约该第一资源的业务的信 号强度可由UE-A根据接收N个业务分别的资源信息的信号强度确定。
例如表5所示，UE-A可根据S102以及S103，存储预约第一资源的N个业务分别的信号强度门限和信号强度之间的对应关系。
业务 业务的优先级信息 信号强度
业务A 门限_A RSRP_A
业务B 门限_B RSRP_B
业务C 门限_C RSRP_C
业务D 门限_D RSRP_D
表5
或者如表6所示，UE-A可存储预约第一资源的N个业务分别的业务类型、信号强度门限和信号强度之间的对应关系。
业务 业务类型 业务的优先级信息 信号强度
业务A 周期性业务 门限_A RSRP_A
业务B 非周期性业务 门限_B RSRP_B
业务C 非周期性业务 门限_C RSRP_C
业务D 周期性业务 门限_D RSRP_D
表6
S104：当第一资源的N个业务分别的信号强度门限以及N个业务分别的信号强度满足第一条件时，UE-A确定待选资源集合包括所述第一资源。
采用以上流程，UE-A可在预约第一资源的业务数量为多个时，综合考虑预约第一资源的N个业务分别的信号强度门限和信号强度，合理判断是否将第一资源作为待选资源，进一步跟待选资源确定传输资源以降低通过传输资源发送业务数据时收到的干扰，能够提高传输性能。
应理解，本申请实施例中，预约该第一资源的N个业务，可包括周期性业务和/或非周期性业务。其中，周期性业务是指，SL业务数据的传输根据固定的周期进行，因此UE-A根据上一个周期范围内感知的周期性业务预约的资源，能够确定该业务在下一个周期范围内预约哪些资源，因此UE-A在下一个周期范围内进行业务数据的发送时，就可以根据该周期性业务对于资源的预约情况合理地选择资源，以降低其他业务数据对于自身发送的业务数据的干扰。非周期性业务是指，SL业务数据的发送不具备固定的发送周期，因此UE-A不能根据上一个周期内非周期业务数据所预约的资源，合理选择下一个周期内自身发送业务所采用的资源。对于非周期性业务，UE-A需要根据来自于发送该非周期业务数据的UE的资源信息获知该非周期业务数据的发送时间，即获知非周期性业务所占用资源的时域位置。
示例性的，UE-A可根据调度业务数据的控制信号，识别该业务是否为周期性业务。具体的，控制信号可携带指示信息(例如，长度为1比特(bit))，该指示信息可指示该业务为周期性业务，或者，指示该业务为非周期性业务。该指示信息可以是SL控制信息(sidelink control information，SCI)。
如图3A所示，UE-A可在感知窗口内感知其他UE发送的业务数据预约的资源。
具体的，对于周期性业务，UE-A可接收来自于其他UE的资源信息。该资源信息可携带在其他UE发送的周期性业务中，用于指示发送业务数据的周期(gap)等信息，则UE-A可获知在与接收该资源信息的资源间隔gap的资源上，会进行下一个周期的业务数据的发 送。
例如图3A所示，UE-A在感知窗口内的资源1’接收到业务1的数据，并获知业务1为周期性业务，则UE-A可获知该业务1预约图3A所示的资源1，资源1与资源1’之间间隔为gap。同理，UE-A在感知窗口内的资源2’接收到业务2的数据，并获知业务2为周期性业务，则UE-A可获知该业务2预约图3A所示的资源2，资源2与资源2’之间间隔为gap。UE-A在感知窗口内的资源3’接收到业务3的数据，并获知业务3为周期性业务，则UE-A可获知该业务3预约图3A所示的资源3，资源3与资源3’之间间隔为gap。
对于非周期性资源，UE-A可接收来自于其他UE发送的资源信息，获知非周期业务预约的资源。其中，资源信息由UE-A在感知窗口内接收，资源信息所指示的非周期性业务预约的资源，与资源信息所占用资源的时域间隔不超过W个时隙(slot)，例如，W为32时隙。
例如图3A所示，UE-A在感知窗口内的资源1”接收到非周期性的业务4的资源信息，指示业务4的数据将在资源1发送，则UE-A可获知该业务4预约图3A所示的资源1，资源1与资源1”之间间隔为不超过W个时隙。同理，UE-A在感知窗口内的资源2”接收到业务5的资源信息，指示业务5的数据将在资源2发送，则UE-A可获知该业务5预约图3A所示的资源2，资源2与资源2”之间间隔不超过W个时隙。此外，业务6的资源信息在图3A所示的资源3”发送，由于资源3”不属于UE-A的感知窗口，UE-A无法接收该资源信息，则UE-A无法获知该业务6的数据将在资源3发送。
应理解，如果gap和W的取值不同，UE-A需要针对gap和W分别设置两个感知窗口，并由UE-A分别在两个感知窗口进行感知，才能感知全部业务预约的资源，保证不出现遗漏。
示例性的，针对存在周期性业务和非周期性业务两种业务类型的场景，可由基站通过信令配置全部UE的周期性业务的周期小于或等于W，或者，也可由协议定义UE的周期性业务的周期小于或等于W。W例如设置为32个时隙。采用该设置，UE-A不需要分别针对周期性业务和非周期性业务单独设置感知窗口，只需要根据W设置感知窗口就能满足对于周期性业务和非周期性业务的感知需求，减少感知次数和降低感知功耗。
此外，如图3B所示，在处于不连续接收(discontinuous reception，DRX)模式时，UE-A在DRX期间不进行数据接收，因此无法确定预约图3B所示资源1的周期性业务和非周期性业务，并且无法感知预约资源2的周期性业务。在这种情况下，UE-A无法获知有业务预约资源1，但是由于UE-A处于DRX期间资源1的感知结果不确定，所以UE-A不将资源1作为待选资源。仅在特殊情况下，比如待选资源占资源池中全部资源的比例过低或者没有足够的待选资源(比如，待选资源的数量小于或小于等于阈值)的情况下，UE-A可以将资源1才能作为待选资源。
下面对S104可能的实现方式进行具体说明。
在S104的一种可能的实现方式中，UE-A可根据N个业务分别的信号强度门限确定第一信号强度门限，以及根据N个业务分别的信号强度确定第一信号强度，当第一信号强度门限大于或等于第一信号强度时，确定满足第一条件，即确定第一资源作为待选资源集合中的资源。或者说，第一条件包括第一信号强度门限大于或等于第一信号强度。
反之，若第一信号强度门限小于第一信号强度，则不满足第一条件，UE-A确定第一资源不作为待选资源集合中的资源。
下面，结合表5或表6所示对应关系表，对UE-A根据N个业务分别的信号强度门限确定第一信号强度门限的方式进行举例说明。
在确定第一信号强度门限时，一种可能的实现方式是，UE-A可将N个业务中，优先级最高的业务的信号强度门限作为第一信号强度门限。
举例来说，优先级最高的业务可以是UE-A感知的预约第一资源的N个业务中优先级最高的周期性业务，或者是N个业务中优先级最高的非周期性业务。具体的，UE-A可从N个业务中的周期性业务中，确定优先级最高的周期性业务，以及从N个业务中的非周期性业务中，确定优先级最高的非周期性业务，之后UE-A可从优先级最高的周期性业务和优先级最高的非周期性业务中，将优先级最高的业务作为优先级最高的业务。例如，N个业务包括表5或表6所示的业务A、业务B以及业务C，若业务A为的优先级最高的周期性业务，业务B为优先级最高的非周期性业务，并且业务A的优先级高于业务B的优先级，即业务A为优先级最高的业务，则UE-A可将业务A对应的门限_A作为第一信号强度门限。
另一种确定第一信号强度门限的方式中，UE-A可将N个业务中，业务的信号强度门限与信号强度的差值最小的业务的信号强度门限作为第一信号强度门限。例如，根据表5或表6，若门限_A-RSRP_A＝a，门限_B-RSRP_B＝b，门限_C-RSRP_C＝c，其中，a＞b＞c，即业务C为信号强度门限与信号强度的差值最小的业务，则UE-A可将业务C对应的门限_C作为第一信号强度门限。
另一种确定第一信号强度门限的方式中，UE-A可将m个业务分别的信号强度门限中最小的信号强度门限，作为第一信号强度门限，其中，m个业务为预约第一资源的N个业务中的部分或全部业务。例如，在表5或表6中，若门限_A＞门限_B＞门限_C，即门限_C为m个业务分别的信号强度门限中小的信号强度门限，则UE-A可将门限_C作为第一信号强度门限。
示例性的，m个业务包括N个业务中，优先级最高的周期性业务和/或优先级最高的非周期性业务。比如，m个业务包括N个业务中，优先级最高的m个业务。
在确定第一信号强度门限时，另一种可能的实现方式是，UE-A可将N个业务中，优先级最高的业务的信号强度门限，或者，N个业务中，业务的信号强度门限与信号强度的差值最小的业务的信号强度门限，或者m个业务分别的信号强度门限中最小的信号强度门限，作为第二信号强度门限，并根据第二信号强度门限与数值M确定第一信号强度门限。其中，M为常数，如5dB。或者，M与N对应。其中，M与N之间的对应关系可如表7所示；或者，M与N之间满足函数关系，比如M＝10*log10(N)(dB)。
N M
2≤N≤3 3dB
4≤N≤7 6dB
8≤N 9dB
表7
示例性的，第一信号强度门限的取值为第二信号强度门限的取值与M的差。
例如，N个业务包括表5或表6所示的业务A、业务B以及业务C，其中，业务A为优先级最高的业务，则UE-A可将(门限_A-M)作为第一信号强度门限。
再比如，表5或表6所示的业务C为信号强度门限与信号强度的差值最小的业务，则UE-A可将(门限_C-M)作为第一信号强度门限。
再比如，表5或表6所示的业务C为信号强度门限最小的业务，则UE-A可将(门限_C-M)作为第一信号强度门限。
在确定第一信号强度时，一种可能的示例中，第一信号强度可根据N个业务中，优先级最高的业务的信号强度确定。例如，若表5或表6所示的业务A为优先级最高的业务，则UE-A可将RSRP_A作为第一信号强度，或者，根据RSRP_A与数值M确定第一信号强度，比如，第一信号确定为RSRP_A与数值M的和，其中，M为常数，如5dB，或者，M与N对应。其中，M与N之间的对应关系可如表7所示；或者，M与N之间满足函数关系，比如M＝10*log10(N)(dB)。
在另一种确定第一信号强度的方式中，第一信号强度可根据m个业务中，信号强度门限最小的业务的信号强度确定，其中，m个业务为N个业务中的部分或全部业务。例如，若表5或表6所示的业务C为信号强度门限最小的业务，则UE-A可将RSRP_C作为第一信号强度。或者，UE-A可根据RSRP_C与数值M确定第一信号强度，确定第一信号强度的具体方法可参照前述对于根据RSRP_A与数值M确定第一信号强度时的说明。
在另一种确定第一信号强度的方式中，第一信号强度可根据N个业务中信号强度门限与信号强度的差值最小的业务的信号强度确定。例如，若表5或表6所示的业务C为信号强度门限与信号强度的差值最小的业务，则UE-A可将RSRP_C作为第一信号强度。或者，UE-A可根据RSRP_C与数值M确定第一信号强度，确定第一信号强度的具体方法可参照前述对于根据RSRP_A与数值M确定第一信号强度时的说明。
在另一种确定第一信号强度的方式中，第一信号强度可根据m个业务分别的信号强度中最大的信号强度确定，其中，m个业务为N个业务中的部分或全部业务。例如，若表5或表6所示的业务B为信号强度最大的业务，则UE-A可将RSRP_B作为第一信号强度。或者，UE-A可根据RSRP_B与数值M确定第一信号强度，确定第一信号强度的具体方法可参照前述对于根据RSRP_A与数值M确定第一信号强度时的说明。
在采用以上所示方式中任意一种确定第一信号强度门限以及第一信号强度后，UE-A可比较第一信号强度门限的取值以及第一信号强度的取值，根据比较结果确定是否满足第一条件，如果满足第一条件则UE-A可执行S103，如果不满足第一条件则UE-A可执行S104，以确定待选资源集合是否包括第一资源。
在一种具体的示例中，若UE-A根据预约第一资源的N个业务中，优先级最高的业务的信号强度门限和信号强度确定是否将第一资源作为待选资源，则本申请实施例提供的资源确定方法可包括如图4所示的以下步骤：
S201：UE-A确定预约第一资源的业务包括表5或表6所示的业务A以及业务B。
S202：UE-A比较业务A的优先级p1与业务B的优先级p2的高低。
若业务A的优先级p1高于(或不低于)业务B的优先级p2，则执行S203-S204。若p2高于(或不低于)p1，则执行S205-S206。若p1优先级与p2相同，则执行S207-S208。
S203：UE-A根据p1以及UE-A需要发送的业务的优先级pj确定门限_A。
其中，门限_A对应于pj以及p1，pj为UE-A需要发送的业务的优先级。
S204：UE-A比较门限_A与RSRP_A的大小。
其中，RSRP_A为UE-A感知的业务A的接收信号的信号强度。
若RSRP_A大于(或不小于)门限_A，则UE-A确定该第一资源不作为待选资源。否则，若RSRP_A小于(或不大于)门限_A，则UE-A确定该第一资源作为待选资源。
S205：UE-A根据p2以及UE-A需要发送的业务的优先级pj确定门限_B。
其中，门限_B对应于pj以及p2，pj为UE-A需要发送的业务的优先级。
S206：UE-A比较门限_B与RSRP_B的大小。
若RSRP_B大于(或不小于)门限_B，则UE-A确定该第一资源不作为待选资源；否则，若RSRP_B小于(或不大于)门限_B，则UE-A确定该第一资源作为待选资源。
S207：UE-A确定RSRP_A和RSRP_B中较大的信号强度值(记为RSRP_max)。
S208：UE-A比较RSRP_max与门限_A(或门限_B)的大小。若RSRP_max大于(或不小于)门限_A，则UE-A确定该第一资源不作为待选资源。否则，若RSRP_max小于(或不大于)门限_A，则UE-A确定该第一资源作为待选资源。
在上例中，如果预约第一资源的业务还包括业务C，例如业务B以及业务C均为非周期性业务，则UE-A在执行S202之前，还可以比较业务B的优先级和业务C的优先级，在业务B的优先级高于(或不低于)业务C的优先级的情况下，再执行S202。
若UE-A根据预约第一资源的N个业务中，信号强度门限与信号强度的差值最小的业务的信号强度门限以及信号强度确定是否将第一资源作为待选资源，则本申请实施例提供的资源确定方法可包括如图5所示的以下步骤：
S301：UE-A确定预约第一资源的业务包括表5或表6所示的业务A以及业务B。
其中，UE-A可根据来自于至少一个UE的资源信息确定表5或表6所示的第一对应关系。示例性的，UE-A可接收来自于UE-B的资源信息，根据该资源信息确定UE-B的业务A预约第一资源；此外，UE-A可接收来自于UE-C的资源信息，根据该资源信息确定UE-C的业务A预约第一资源。或者，UE-A可接收来自于UE-B的资源信息，根据该资源信息获知业务A以及业务B预约第一资源，此时业务A以及业务B可以均为UE-B的业务，或者分别为不同UE的业务，这里不进行具体限定。
S302：UE-A确定业务A的信号强度门限与信号强度，以及确定业务B的信号强度门限与信号强度。
其中，业务A的信号强度门限为门限_A，业务A的信号强度为RSRP_A，业务B的信号强度门限为门限_B，业务B的信号强度为RSRP_B。
S303：UE-A确定业务A的信号强度门限与信号强度的差a，以及确定业务B的信号强度门限与信号强度的差b。其中，a＝门限_A-RSRP_A，b＝门限_B-RSRP_B。
S304：UE-A比较业务A的信号强度门限与信号强度的差a，与业务B的信号强度门限与信号强度的差b的大小。
若a小于b，则执行S305。若b小于a，则执行S306。若a与b相等，则执行S305或S306中的任意一个。
S305：UE-A比较(门限_A-M)与RSRP_A的大小。
其中，M为正整数。M为常数，或者M与N对应，比如，M＝10*log10(N)。
若RSRP_A大于(或不小于)(门限_A-M)，则UE-A确定该第一资源不作为待选资源。否则，若RSRP_A小于(或不大于)(门限_A-M)，则UE-A确定该第一资源作为待选资源。
S306：UE-A比较(门限_B-M)与RSRP_B的大小。
其中，M为正整数。M为常数，或者M与N对应，比如，M＝10*log10(N)。
若RSRP_B大于(门限_B-M)，则UE-A确定该第一资源不作为待选资源；否则，若 RSRP_B小于(或不大于)(门限_B-M)，则UE-A确定该第一资源作为待选资源。
若UE-A根据预约第一资源的N个业务分别的信号强度门限中，最小的信号强度门限与该N个业务分别的信号强度中，最大的信号强度确定是否将第一资源作为待选资源，则本申请实施例提供的资源确定方法可包括如图6所示的以下步骤：
S401：UE-A确定预约第一资源的业务包括表5或表6所示的业务A以及业务B。
其中，UE-A可根据来自于至少一个UE的资源信息确定表5或表6所示的第一对应关系。示例性的，UE-A可接收来自于UE-B的资源信息，根据该资源信息确定UE-B的业务A预约第一资源；此外，UE-A可接收来自于UE-C的资源信息，根据该资源信息确定UE-C的业务A预约第一资源。或者，UE-A可接收来自于UE-B的资源信息，根据该资源信息获知业务A以及业务B预约第一资源，此时业务A以及业务B可以均为UE-B的业务，或者分别为不同UE的业务，这里不进行具体限定。
S402：UE-A确定业务A的信号强度门限与信号强度，以及确定业务B的信号强度门限与信号强度。
其中，业务A的信号强度门限为门限_A，业务A的信号强度为RSRP_A，业务B的信号强度门限为门限_B，业务B的信号强度为RSRP_B。
S403：UE-A确定业务A的信号强度门限与业务B的信号强度门限中最小的信号强度门限(表示为门限_min)，以及确定业务A的信号强度与业务B的信号强度中最大的信号强度(表示为RSRP_max)。
示例性的，门限_min＝min{门限_A，门限_B}，RSRP_max＝max{RSRP_A，RSRP_B}。
S404：UE-A比较该最小的信号强度门限与该最大的信号强度的大小。
若RSRP_max大于(或不小于)门限_min，则UE-A确定该第一资源不作为待选资源。否则，若RSRP_max小于(或不大于)门限_min，则UE-A确定该第一资源作为待选资源。
应理解，若预约第一资源的业务还包括表5或表6所示的业务C以及业务D，则S503中，门限_min＝min{门限_A，门限_B，门限_C，门限_D}，RSRP_max＝{RSRP_A，RSRP_B，RSRP_C，RSRP_D}。或者，UE-A在确定业务A为预约第一资源的优先级最高的周期性业务，且业务B为预约第一资源的优先级最高的非周期性业务后，执行S401-S404所示步骤。
若UE-A根据预约第一资源的N个业务分别的信号强度门限中，最小的信号强度门限与该N个业务分别的信号强度的总和确定是否将第一资源作为待选资源，则本申请实施例提供的资源确定方法可包括如图7A所示的以下步骤：
S501：UE-A确定预约第一资源的业务包括表5或表6所示的业务A以及业务B。
其中，UE-A可根据来自于至少一个UE的资源信息确定表5或表6所示的第一对应关系。示例性的，UE-A可接收来自于UE-B的资源信息，根据该资源信息确定UE-B的业务A预约第一资源；此外，UE-A可接收来自于UE-C的资源信息，根据该资源信息确定UE-C的业务A预约第一资源。或者，UE-A可接收来自于UE-B的资源信息，根据该资源信息获知业务A以及业务B预约第一资源，此时业务A以及业务B可以均为UE-B的业务，或者分别为不同UE的业务，这里不进行具体限定。
S502：UE-A确定业务A的信号强度门限与信号强度，以及确定业务B的信号强度门限与信号强度。
其中，业务A的信号强度门限为门限_A，业务A的信号强度为RSRP_A，业务B的 信号强度门限为门限_B，业务B的信号强度为RSRP_B。
S503：UE-A确定业务A的信号强度门限与业务B的信号强度门限中最小的信号强度门限(表示为门限_min)，以及确定业务A的信号强度与业务B的信号强度的总和(表示为RSRP_sum)。
示例性的，门限_min＝min{门限_A，门限_B}，RSRP_sum＝RSRP_A+RSRP_B。
S504：UE-A比较该最小的信号强度门限与该信号强度的总和的大小。
若RSRP_sum大于(或不小于)门限_min，则UE-A确定该第一资源不作为待选资源。否则，若RSRP_sum小于(或不大于)门限_min，则UE-A确定该第一资源作为待选资源。
应理解，若预约第一资源的业务还包括表5或表6所示的业务C以及业务D，则S503中，门限_min＝min{门限_A，门限_B，门限_C，门限_D}，RSRP_sum＝RSRP_A+RSRP_B+RSRP_C+RSRP_D。或者，UE-A在确定业务A为预约第一资源的优先级最高的周期性业务，且业务B为预约第一资源的优先级最高的非周期性业务后，执行S501-S504所示步骤。
在S104的另一种可能的实现方式中，UE-A可在N个业务中每个业务的信号强度门限均大于或等于所述信号强度门限所属业务的信号强度时，确定满足第一条件，即确定第一资源作为待选资源集合中的资源。或者说，第一条件包括N个业务(或N个业务中的n个业务)中每个业务的信号强度门限均大于或等于所述信号强度门限所属业务的信号强度。
反之，若N个业务中至少一个业务的信号强度门限小于所述信号强度门限所属业务的信号强度，则不满足第一条件，UE-A确定第一资源不作为待选资源集合中的资源。
例如，针对表2所示的资源A，UE-A可确定业务1和业务2的优先级分别为1和2，UE-A可针对业务1，确定信号强度门限1以及RSRP1，以及针对业务2确定信号强度门限2以及RSRP2。在UE-A确定信号强度门限1不小于RSRP1且信号强度门限2不小于RSRP2时，UE-A确定待选资源集合包括资源A，或者说，UE-A确定资源A为待选资源。否则，在UE-A确定信号强度门限1小于RSRP1或者信号强度门限2小于RSRP2时，UE-A确定待选资源集合不包括资源A，或者说，UE-A确定资源A不属于待选资源。
在一种可能的实现方式中，UE-A还可根据N个业务中的n个业务的信号强度门限和信号强度确定是否满足第一条件，以节省计算复杂度。其中，n小于N，n个业务占N个业务的比例不小于阈值，如50％。UE-A可在n个业务中每个业务的信号强度门限均大于或等于所述信号强度门限所属业务的信号强度时，确定满足第一条件，或者可在n个业务中至少一个业务的信号强度门限小于所述信号强度门限所属业务的信号强度时，确定不满足第一条件。
示例性的，n个业务可包括N个业务中，优先级最高的a个周期性业务、优先级最高的b个非周期性业务、信号强度门限最小的c个周期性业务、信号强度门限最小的d个非周期性业务、信号强度门限与信号强度的差值最小的e个周期性业务，或者信号强度门限与信号强度的差值最小的f个非周期性业务中的部分或全部。其中，a、b、c、d、e以及f为正整数。
应理解，以上a、b、c、d、e以及f的取值可由UE-A接入的基站配置，或者预先存储于UE-A中。
示例性的，若n个业务包括表5或表6所示的业务A以及业务B，则UE-A可判断门限_A是否不大于RSRP_A(以下称为第一判断结果)，判断结果若为是，则记为“1”，若为否，则记为“0”，以及判断门限_B是否不大于RSRP_B(以下称为第二判断结果)，判断结 果若为是，则记为“1”，若为否，则记为“0”。此后，UE-A可根据第一判断结果以及第二判断结果取与运算，根据运算结果确定是否将第一资源作为待选资源。
具体的，若第一判断结果记为“1”，第一判断结果记为“0”，“1”与“0”进行取与运算后的结果为“0”，表示第一资源不作为待选资源。若第一判断结果记为“0”，第一判断结果记为“1”，“0”与“1”进行取与运算后的结果为“0”，表示第一资源不作为待选资源。若第一判断结果记为“0”，第一判断结果记为“0”，“0”与“0”进行取与运算后的结果为“0”，表示第一资源不作为待选资源。若第一判断结果记为“1”，第一判断结果记为“1”，“1”与“1”进行取与运算后的结果为“1”，表示第一资源作为待选资源。
在S104之后，UE-A可根据待选资源集合确定传输资源，并根据该传输资源进行SL传输。其中，在根据待选资源集合确定传输资源时，若待选资源集合包括该第一资源以及第二资源，其中，预约第二资源的业务的数量为1个，则UE-A可根据第一资源的概率以及第二资源的概率确定传输资源，其中，概率用于表示待选资源被确定为传输资源的可能性，概率的取值越大，待选资源被选为传输资源的可能性越大。其中，第一资源的概率小于第二资源的概率，使得被1个业务预约的资源更有可能被指定为传输资源，以降低通过传输资源发送业务数据时受到的传输干扰。
示例性的，无业务预约的待选资源的概率为基础概率g0，被一个业务预约的待选资源的概率为g1，被两个业务预约的待选资源的概率为g2，则g2＜g1＜g0。
具体的，第一资源的概率为第二资源的概率的k倍，k小于1。例如，k＝1/2。再比如，第一资源的概率gN与N有关，并且N越大，gN越小，比如，gN与基础概率g0满足gN＝g0/(N+1)，N为预约第一资源的业务数量。此外，第二资源的概率可以是基础概率g0的l倍，l小于1。例如，l＝1/2。
应理解，UE-A确定的待选资源的数量为Q，Q为正整数，若通过f(q)表示被q个业务预约的待选资源的概率，则∑f(q)*q＝1，其中，q＝0,1,2……Q。据此，UE-A可确定每个待选资源的概率。
示例性的，可令待选资源集合中全部待选资源的概率的总和为1，比如，第一资源的概率为第二资源的k倍，k＝3(比如，N＝2)，若待选资源集合由第一资源以及第二资源组成，则第一资源的概率为0.25，第二资源的概率为0.75。
如图7B所示，本申请实施例还提供一种方法，应用于周期性业务和非周期性业务共存的场景，用于减少UE的感知次数和降低感知功耗。该方法可包括以下步骤：
S601：UE-A、UE-B以及UE-C配置周期性业务的周期gap，gap的取值不大于(或小于)W个时隙，其中，资源信息所指示的非周期性业务预约的资源与资源信息所占用资源的时域间隔不超过W个时隙。例如，W＝32。
可选的，可由基站配置或通过预配置的方式，令UE-A、UE-B以及UE-C配置周期性业务的周期gap。
可选的，可由基站配置或通过预配置的方式，令UE-A、UE-B以及UE-C配置W的取值。
S602：UE-B发送业务A的资源信息，UE-C发送业务B的资源信息。
其中，业务A为周期性业务，业务B为非周期性业务。其中，业务A的周期不超过W。
S603：UE-A以W为周期进行感知，接收业务A的资源信息以及业务B的资源信息。
据此，UE-A可根据业务A的资源信息以及业务B的资源信息确定进行侧行传输所采用的传输资源。
采用该方法，UE-A不需要分别针对周期性业务和非周期性业务单独设置感知窗口，只需要根据W设置感知窗口就能满足对于周期性业务和非周期性业务的感知需求，减少感知次数和降低感知功耗。
