具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
以下，对本申请实施例中的部分用语进行解释说明，以便于本领域技术人员理解。
本申请实施例中涉及的“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B的情况，其中A，B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项(个)”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a，b，或c中的至少一项(个)，可以表示：a，b，c，a-b，a-c，b-c，或a-b-c，其中a，b，c可以是单个，也可以是多个。
以及，除非有相反的说明，本申请实施例提及“第一”、“第二”等序数词是用于对多个对象进行区分，不用于限定多个对象的顺序、时序、优先级或者重要程度。例如，第一信息和第二信息，只是为了区分不同的信息，而并不是表示这两种信息的内容、优先级、发送顺序或者重要程度等的不同。
应理解，在本申请的实施例中提到的“指示”可以是直接指示，也可以是间接指示，还可以是表示具有关联关系。举例说明，A指示B，可以表示A直接指示B，例如B可以通过A获取；也可以表示A间接指示B，例如A指示C，B可以通过C获取；还可以表示A和B之间具有关联关系。
在本申请实施例的描述中，术语“对应”可表示两者之间具有直接对应或间接对应的关系，也可以表示两者之间具有关联关系，也可以是指示与被指示、配置与被配置等关系。
本申请实施例中，“预定义”或“预配置”可以通过在设备(例如，包括终端设备和网络设备)中预先保存相应的代码、表格或其他可用于指示相关信息的方式来实现，本申请对于其具体的实现方式不做限定。比如预定义可以是指协议中定义的。
本申请实施例中，所述“协议”可以指通信领域的标准协议，例如可以包括LTE协议、NR协议以及应用于未来的通信系统中的相关协议，本申请对此不做限定。
为了便于理解本申请，首先对本申请涉及的概念进行解释。
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、部分网络覆盖侧行通信和网络覆盖外侧行通信。
参见图1a，图1a为网络覆盖内侧行通信的示意图。如图1a所示，在网络覆盖内侧行通信的情况下，所有进行侧行通信的终端均位于同一基站的覆盖范围内，从而，终端均可以接收基站的配置信令，基于相同的侧行配置进行侧行通信。
参见图1b，图1b为部分网络覆盖侧行通信的示意图。如图1b所示，在部分网络覆盖侧行通信的情况下，部分进行侧行通信的终端位于基站的覆盖范围内，位于基站的覆盖范围内的终端可以接收基站的配置信令，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。
参见图1c，图1c为网络覆盖外侧行通信的示意图。如图1c所示，在网络覆盖外侧行通信的情况下，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信息确定侧行配置进行侧行通信。
设备到设备通信：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，因此具有更高的频谱效率以及更低的传输时延。车联网系统采用终端到终端直接通信的方式，在第3代合作伙伴计划(third generation partnership project，3GPP)定义了两种传输模式：第一模式和第二模式。
在第一模式中，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发送数据。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。例如，在图1a中，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。
在第二模式中，终端在资源池中选取资源进行数据传输。例如，在图1c中，终端位于网络覆盖范围外，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。再例如，在图1a中，终端也可以在网络配置的资源池中自主选取传输资源进行侧行传输。
在新空口(new radio，NR)-车辆到其他设备(vehicle to everything，V2X)中，需要支持自动驾驶，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。
在长期演进(long term evaluation，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。
参见图2a，图2a为NR-V2X中单播传输方式的示意图。对于单播传输方式，其接收端只有一个终端，如图2a所示，终端1和终端2之间进行单播传输。
参见图2b，图2b为NR-V2X中组播传输方式的示意图。对于组播传输方式，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2b所示，终端1、终端2、终端3和终端4构成一个通信组，其中，终端1发送数据，该组内的其他终端设备都是接收端。
参见图2c，图2c为NR-V2X中广播传输方式的示意图。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2c所示，终端1是发送端终端，其周围的其他终端，包括终端2、终端3、终端4、终端5和终端6都是接收端。
在模式2(mode2)中，即上述第二模式，终端自主从资源池中选取传输资源。在3GPP中给出了终端基于侦听进行资源选取的过程，包括基于完全侦听(full sensing)的方式和基于部分侦听(partial sensing)的方式。
非连续接收(discontinuous reception，DRX)机制：在无线网络中，当有数据需要进行传输时，用户终端(user equipment，UE)要一直监听物理下行控制信道(physical downlink control channel，PDCCH)，根据网络侧发送的指示消息对数据进行收发，这样导致UE的功耗和数据传输的时延都比较大。因此3GPP标准协议在LTE系统中引入非连续接收机制的节能策略。DRX的基本机制是为处于无线资源控制(radio resource control，RRC)连接态的UE配置一个DRX周期(cycle)。
参见图3，图3为DRX周期的示意图。如图3所示，DRX cycle由激活期(active time)和非激活期(inactive time)组成。在active time(又称为on duration)时间内，UE监听并接收PDCCH。在inactive time(又称为opportunity for DRX)时间内，UE不接收PDCCH以减少功耗。其中，opportunity for DRX 时间又可以称为DRX off duration，在DRX操作中，终端根据网络配置的定时器参数来控制终端on duration和off duration。
侧行链路(sidelink，SL)的DRX机制：在SL技术中，为了达到节能目的，在SL中引入DRX机制，即SL DRX。在SL DRX机制中，终端在激活期内接收其他终端发送的数据，如果没有检测到数据，在激活期结束后，进入休眠状态，以节省功耗。在SL DRX中引入了定时器控制激活期或者非激活期，定时器包括drx-HARQ-RTT-Timer、drx-onDurationTimer、drx-retransmissionTimer、drx-inactivityTimer等，在drx-onDurationTimer、drx-retransmissionTimer、drx-inactivityTimer等定时器运行时，终端处于激活期。对于单播通信，接收端的DRX是由发送端或者发送端的网络设备配置的。对于组播或者广播通信，DRX配置参数是根据层2(L2)目标标识(ID)或服务质量(quality of service，QoS)参数确定的。
在基于SL DRX的侧行传输系统中，接收端配置了DRX，接收端只能在激活期(active time)内接收发送端发送的侧行数据。当接收端接收到发送端发送的初传数据，会激活drx-inactivityTimer和/或drx-retransmissionTimer，并且在定时器失效前，接收端仍然处于激活期，此时发送端可以在该定时器的有效期内进行重传。
如上介绍了本申请的背景技术，下面介绍本申请实施例的技术特征。
参见图4，图4为本申请实施例提供的一种确定侧行传输资源的方法的示意图。如图4所示，该确定侧行传输资源的方法包括：
S401、终端设备获取第一指示信息，第一指示信息用于指示激活期。
可选的，所述终端设备是发送端终端设备。
具体的，在基于SL DRX的侧行传输系统中，发送端获取第一指示信息，该第一指示信息用于指示接收端的SLDRX激活期。
可选的，终端设备从高层(例如媒体接入控制(media access control，MAC)层)获取第一指示信息。
S402、终端设备根据第一指示信息，确定候选传输资源集合，候选传输资源集合中包括位于激活期内的传输资源。
可选的，终端设备根据第一指示信息，确定候选传输资源集合的方法可以是：终端设备确定第一资源选择窗和激活期的重叠区域包括的第一时隙的数量；根据第一时隙的数量与第一门限的大小关系，确定候选传输资源集合，其中，第一时隙对应于重叠区域内的任意一个时隙，或者，第一时隙是属于Y个时隙中的时隙，Y个时隙是终端设备进行部分侦听时在第一资源选择窗内选取的，Y为正整数。
在一些实施方式中，第一资源选择窗和激活期的重叠区域包括的第一时隙是位于第一资源池内的时隙，该第一资源池是所述终端设备进行侦听时使用的资源池，或，该第一资源池是所述终端设备进行侧行传输时所使用的资源池。例如，终端设备有待传输的侧行数据时，确定使用第一资源池进行侧行传输，终端设备在该第一资源池内进行侦听，并且根据侦听结果选取候选传输资源，利用该候选传输资源进行侧行传输。
具体的，终端设备确定第一资源选择窗，确定第一资源选择窗和激活期的重叠区域包括的第一时隙 的数量。当终端设备进行完全侦听时，第一时隙对应于重叠区域内的任意一个时隙，此时将重叠区域内包括的所有时隙的数量与第一门限进行比较，确定候选传输资源集合。当终端设备进行部分侦听时，第一时隙是属于Y个时隙中的时隙，此时将重叠区域内属于Y个时隙的时隙数量与第一门限进行比较，确定候选传输资源集合；其中，Y个时隙是终端设备进行部分侦听时在第一资源选择窗内选取的，终端设备根据侦听结果针对基于该Y个时隙确定的候选传输资源集合进行资源排除，进而确定候选传输资源集合。
可选的，若第一时隙的数量大于第一门限，则候选传输资源集合中的传输资源为位于激活期内的传输资源。
具体的，若第一时隙的数量大于第一门限，则候选传输资源集合中的传输资源只包括位于激活期内的传输资源。发送端在发送侧行数据时，选取的侧行传输资源为位于接收端的激活期内的传输资源，接收端可以在激活期内接收发送端发送的侧行数据。
可选的，若第一时隙的数量小于或等于第一门限，则候选传输资源集合中还包括不属于激活期内的传输资源。
具体的，若第一时隙的数量小于或等于第一门限，则候选传输资源集合中包括位于激活期内的传输资源，还包括不属于激活期内的传输资源。发送端在发送侧行数据时，选取的侧行传输资源包括位于接收端的激活期内的传输资源，接收端可以在激活期内接收发送端发送的侧行数据。
在一种可能的实施方式中，第一门限是根据终端设备的预配置信息或者网络配置信息确定。例如，通过侧行带宽部分(bandwidth part，BWP)配置信息或资源池配置信息指示该第一门限。
在另一种可能的实施方式中，第一门限是与优先级相关的参数，第一门限是根据终端设备在确定候选传输资源集合时使用的发送端优先级信息和/或从其他终端设备接收到的优先级信息确定。
上述方法中，终端设备根据第一指示信息确定候选传输资源集合，其中第一指示信息用于指示激活期，候选传输资源集合中包括位于激活期内的传输资源。在基于SL DRX的侧行传输系统中，发送端根据接收端的激活期，确定候选传输资源集合，其中包括位于接收端的激活期内的传输资源。这样，发送端在发送侧行数据时，选取的侧行传输资源包括位于接收端的激活期内的传输资源，接收端可以在激活期内接收发送端发送的侧行数据，解决了发送端如何确定侧行传输资源的问题。
参见图5，图5为本申请实施例提供的第一资源选择窗和激活期的重叠区域的示意图。如图5所示，终端设备确定的第一资源选择窗为[n+T1，n+T2]，其中，基于终端设备实现选取T1，T1不小于0且不大于Tproc，Tproc由终端的处理时间确定。当第一资源选择窗的最小时长小于剩余包延迟预算(packet delay budget，PDB)对应的时隙数时，基于终端设备实现选择T2，并且T2不小于第一资源选择窗的最小时长且不大于剩余PDB对应的时隙数，否则T2等于剩余PDB对应的时隙数。其中，第一资源选择窗的最小时长是根据资源池配置参数确定的。
在一种可能的实施方式中，第一资源选择窗是终端设备确定的具有最大时域范围的资源选择窗，从而使得第一资源选择窗和激活期的重叠区域最大。例如，终端设备在确定T2时，可以将T2等于剩余PDB对应的时隙数。
参见图6a和图6b，图6a为本申请实施例提供的一种重叠区域的示意图，图6b为本申请实施例提供的另一种重叠区域的示意图。如图6a所示，第一资源选择窗和激活期的重叠区域为图中的重叠区域1，重叠区域1包括的第一时隙的数量大于第一门限(图中的Thd1)，因此，终端设备可以在该重叠区域1内确定候选传输资源集合。如图6b所示，由于DRX配置是周期性的，因此，激活期也可能是周期性的。此时第一资源选择窗和激活期的重叠区域包括所有的重叠区域，也就是包括图中的重叠区域2和重叠区域3。重叠区域2和重叠区域3包括的第一时隙的数量大于第一门限(图中的Thd1)，因此，终端设备可以在该重叠区域2和该重叠区域3内确定候选传输资源集合。
参见图7，图7为本申请实施例提供的另一种确定侧行传输资源的方法的示意图。如图7所示，该确定侧行传输资源的方法包括：
S701、终端设备获取第一指示信息，第一指示信息用于指示激活期。
可选的，所述终端设备是发送端终端设备。
具体的，在基于SL DRX的侧行传输系统中，发送端获取第一指示信息，该第一指示信息用于指示接收端的SLDRX激活期。
可选的，终端设备从高层(例如媒体接入控制(media access control，MAC)层)获取第一指示信息。
S702、终端设备确定第一资源选择窗和激活期的重叠区域包括的第一时隙的数量。
具体的，终端设备确定第一资源选择窗，确定第一资源选择窗和激活期的重叠区域包括的第一时隙的数量。其中，第一时隙对应于重叠区域内的任意一个时隙，或者，第一时隙是属于Y个时隙中的时隙，Y个时隙是终端设备进行部分侦听时在第一资源选择窗内选取的，Y为正整数。
在一些实施方式中，第一资源选择窗和激活期的重叠区域包括的第一时隙是位于第一资源池内的时隙，该第一资源池是所述终端设备进行侦听时使用的资源池，或，该第一资源池是所述终端设备进行侧行传输时所使用的资源池。例如，终端设备有待传输的侧行数据时，确定使用第一资源池进行侧行传输，终端设备在该第一资源池内进行侦听，并且根据侦听结果选取候选传输资源，利用该候选传输资源进行侧行传输。
当终端设备进行完全侦听时，第一时隙对应于重叠区域内的任意一个时隙，此时第一时隙的数量为重叠区域内包括的所有时隙的数量。当终端设备进行部分侦听时，第一时隙是属于Y个时隙中的时隙，Y个时隙是终端设备进行部分侦听时在第一资源选择窗内选取的，终端设备根据侦听结果针对基于该Y个时隙确定的候选传输资源集合进行资源排除，进而确定候选传输资源集合。此时第一时隙的数量为重叠区域内属于Y个时隙的时隙数量。
在一种可能的实施方式中，第一资源选择窗是终端设备确定的具有最大时域范围的资源选择窗，从而使得第一资源选择窗和激活期的重叠区域最大。例如，终端设备在确定T2时，可以将T2等于剩余PDB对应的时隙数。
S703、若第一时隙的数量大于第一门限，终端设备根据重叠区域确定第二资源选择窗。
可选的，终端设备根据重叠区域确定第二资源选择窗，其中，第二资源选择窗对应的时域范围小于 或等于重叠区域对应的时域范围。例如，终端设备根据重叠区域的起始位置确定第二资源选择窗的起始位置，根据重叠区域的结束位置确定第二资源选择窗的结束位置。
在一种可能的实施方式中，第一门限是根据终端设备的预配置信息或者网络配置信息确定。例如，通过侧行BWP配置信息或资源池配置信息指示该第一门限。
在另一种可能的实施方式中，第一门限是与优先级相关的参数，第一门限是根据终端设备在确定候选传输资源集合时使用的发送端优先级信息和/或从其他终端设备接收到的优先级信息确定。
参见图8a和图8b，图8a为本申请实施例提供的一种第二资源选择窗的示意图，图8b为本申请实施例提供的另一种第二资源选择窗的示意图。如图8a所示，第一资源选择窗和激活期的重叠区域只有一个，并且重叠区域包括的第一时隙的数量大于第一门限。此时将该重叠区域设置为第二资源选择窗，也即图中的第二资源选择窗1。如图8b所示，第一资源选择窗和激活期的重叠区域有两个，这两个重叠区域时域不相邻，并且这两个重叠区域包括的第一时隙的数量大于第一门限。此时将这两个重叠区域设置为第二资源选择窗，即第二资源选择窗包括图中的第二资源选择窗2和第二资源选择窗3，第二资源选择窗2和第二资源选择窗3时域不连续。
S704、终端设备在第二资源选择窗中确定候选传输资源集合。
可选的，终端设备在第二资源选择窗中确定候选传输资源集合的方法可以是：终端设备初始化候选传输资源集合，初始化的候选传输资源集合包括第二资源选择窗内的候选单时隙资源；在初始化的候选传输资源集合中进行资源排除，得到候选传输资源集合。
具体的，终端设备根据第二资源选择窗内的候选单时隙资源(candidate single-slot resource)对候选传输资源集合进行初始化。当终端设备进行完全侦听时，初始化的候选传输资源集合包括第二资源选择窗内所有时隙对应的全部候选单时隙资源。当终端设备进行部分侦听时，初始化的候选传输资源集合包括第二资源选择窗内属于Y个时隙中的时隙对应的全部候选单时隙资源。其中，部分侦听包括周期性的部分侦听(periodic-based partial sensing)和/或连续部分侦听(contiguous partial sensing)。
例如，如图8a和图8b所示，第一资源选择窗和激活期的重叠区域包括的第一时隙的数量大于第一门限。此时，终端设备基于完全侦听确定候选传输资源集合，初始化的候选传输资源集合包括第二资源选择窗内的所有候选单时隙资源。也就是说，图8a中初始化的候选传输资源集合包括第二资源选择窗1内的所有候选单时隙资源，图8b中初始化的候选传输资源集合包括第二资源选择窗2和第二资源选择窗3内的所有候选单时隙资源。
再例如，如图9a和图9b所示，图9a为本申请实施例提供的一种部分侦听时第二资源选择窗的示意图，图9b为本申请实施例提供的另一种部分侦听时第二资源选择窗的示意图。在图9a和图9b中，第一资源选择窗和激活期的重叠区域包括的第一时隙的数量大于第一门限。此时终端设备基于部分侦听确定候选传输资源集合，初始化的候选传输资源集合包括第二资源选择窗内第一时隙对应的全部候选单时隙资源，第一时隙是属于Y个时隙中的时隙，Y个时隙是终端设备进行部分侦听时在第一资源选择窗内选取的，Y为正整数。也就是说，图9a中初始化的候选传输资源集合包括第二资源选择窗1内第一时隙对应的全部候选单时隙资源，图9b中初始化的候选传输资源集合包括第二资源选择窗2和第二资 源选择窗3内第一时隙对应的全部候选单时隙资源。
进一步的，终端设备在初始化的候选传输资源集合中进行资源排除，确定候选传输资源集合。由于第二资源选择窗只包括重叠区域，所以最终确定的候选传输资源集合只包括重叠区域内的传输资源。
在一种可能的实施方式中，第一时隙的数量大于第一资源选择窗的最小长度对应的时隙数量。
上述方法中，终端设备获取第一指示信息，第一指示信息用于指示激活期。终端设备确定第一资源选择窗和激活期的重叠区域包括的第一时隙的数量。若第一时隙的数量大于第一门限，终端设备根据重叠区域确定第二资源选择窗。终端设备在第二资源选择窗中确定候选传输资源集合。在基于SL DRX的侧行传输系统中，发送端在发送侧行数据时，选取的侧行传输资源为位于接收端的激活期内的传输资源，接收端可以在激活期内接收发送端发送的侧行数据，解决了发送端如何确定侧行传输资源的问题。
参见图10，图10为本申请实施例提供的另一种确定侧行传输资源的方法的示意图。如图10所示，该确定侧行传输资源的方法包括：
S1001、终端设备获取第一指示信息，第一指示信息用于指示激活期。
可选的，所述终端设备是发送端终端设备。
具体的，在基于SL DRX的侧行传输系统中，发送端获取第一指示信息，该第一指示信息用于指示接收端的SL DRX激活期。
可选的，终端设备从高层(例如媒体接入控制(media access control，MAC)层)获取第一指示信息。
S1002、终端设备确定第一资源选择窗和激活期的重叠区域包括的第一时隙的数量。
具体的，终端设备确定第一资源选择窗，确定第一资源选择窗和激活期的重叠区域包括的第一时隙的数量。其中，第一时隙对应于重叠区域内的任意一个时隙，或者，第一时隙是属于Y个时隙中的时隙，Y个时隙是终端设备进行部分侦听时在第一资源选择窗内选取的，Y为正整数。
在一些实施方式中，第一资源选择窗和激活期的重叠区域包括的第一时隙是位于第一资源池内的时隙，该第一资源池是所述终端设备进行侦听时使用的资源池，或，该第一资源池是所述终端设备进行侧行传输时所使用的资源池。例如，终端设备有待传输的侧行数据时，确定使用第一资源池进行侧行传输，终端设备在该第一资源池内进行侦听，并且根据侦听结果选取候选传输资源，利用该候选传输资源进行侧行传输。
当终端设备进行完全侦听时，第一时隙对应于重叠区域内的任意一个时隙，此时第一时隙的数量为重叠区域内包括的所有时隙的数量。当终端设备进行部分侦听时，第一时隙是属于Y个时隙中的时隙，Y个时隙是终端设备进行部分侦听时在第一资源选择窗内选取的，终端设备根据侦听结果针对基于该Y个时隙确定的候选传输资源集合进行资源排除，进而确定候选传输资源集合。此时第一时隙的数量为重叠区域内属于Y个时隙的时隙数量。
在一种可能的实施方式中，第一资源选择窗是终端设备确定的具有最大时域范围的资源选择窗，从而使得第一资源选择窗和激活期的重叠区域最大。例如，终端设备在确定T2时，可以将T2等于剩余PDB对应的时隙数。
S1003、若第一时隙的数量小于或等于第一门限，终端设备在第一资源选择窗中确定候选传输资源集合。
若第一时隙的数量小于或等于第一门限，则候选传输资源集合中包括位于激活期内的传输资源，还包括不属于激活期内的传输资源。
在一种可能的实施方式中，第一门限是根据终端设备的预配置信息或者网络配置信息确定。例如，通过侧行BWP配置信息或资源池配置信息指示该第一门限。
在另一种可能的实施方式中，第一门限是与优先级相关的参数，第一门限是根据终端设备在确定候选传输资源集合时使用的发送端优先级信息和/或从其他终端设备接收到的优先级信息确定。
可选的，第一时隙的数量大于第二门限，其中，第二门限小于第一门限，第二门限是根据终端设备的预配置信息或者网络配置信息确定。
具体的，终端确定第一资源选择窗，使得第一资源选择窗与激活期有重叠区域。重叠区域内第一时隙的数量大于该第二门限。
可选的，在第一资源选择窗中确定候选传输资源集合之前，终端设备获取第一参数，根据该第一参数，确定候选传输资源集合中位于重叠区域内的传输资源数量的第三门限。
具体的，终端设备获取第一参数，该第一参数用于确定重叠区域内的传输资源数量的第三门限。在一种可能的实施方式中，第一参数表示为传输资源的数量，根据该第一参数即可确定第三门限，例如将第三门限设置为第一参数表示的传输资源的数量。在另一种可能的实施方式中，第一参数表示为比例系数Z，根据重叠区域内全部的传输资源数量M以及该第一参数Z，即可确定第三门限为M*Z。其中，当终端设备采用完全侦听时，重叠区域内全部的传输资源数量M包括重叠区域内所有时隙对应的候选单时隙资源的数量。当终端设备采用部分侦听时，重叠区域内全部的传输资源数量M包括重叠区域内属于Y个时隙中的时隙对应的候选单时隙资源的数量。
可选的，终端设备在第一资源选择窗中确定候选传输资源集合的方法可以是：终端设备初始化候选传输资源集合，初始化的候选传输资源集合包括第一资源选择窗内的候选单时隙资源；在初始化的候选传输资源集合中进行资源排除，得到候选传输资源集合，候选传输资源集合中位于重叠区域内的传输资源数量大于或等于第三门限。
具体的，终端设备根据第一资源选择窗内的候选单时隙资源(candidate single-slot resource)对候选传输资源集合进行初始化。当终端设备进行完全侦听时，初始化的候选传输资源集合包括第一资源选择窗内包括的全部候选单时隙资源。当终端设备进行部分侦听时，初始化的候选传输资源集合包括第一资源选择窗内包括的第二时隙对应的全部候选单时隙资源，其中，第二时隙是属于Y个时隙中的时隙，Y个时隙是终端设备进行部分侦听时在第一资源选择窗内选取的，Y为正整数。
在一种可能的实施方式中，终端设备确定候选传输资源集合的方法可以是：终端设备在初始化的候选传输资源集合中进行资源排除。若经过资源排除的候选传输资源集合中剩余的候选单时隙资源数量小于第二参数，则终端设备重新初始化候选传输资源集合，在初始化的候选传输资源集合中重新进行资源排除，直到候选传输资源集合中剩余的候选单时隙资源数量大于或等于第二参数。其中，第二参数可以 根据第一资源选择窗内包括的总资源数量的X％确定，X例如为20，35或50。若经过资源排除的候选传输资源集合中剩余的位于重叠区域内的传输资源数量小于第三门限，则终端设备重新初始化候选传输资源集合，在初始化的候选传输资源集合中重新进行资源排除，直到候选传输资源集合中剩余的位于重叠区域内的传输资源数量大于或等于第三门限。
在另一种可能的实施方式中，终端设备确定候选传输资源集合的方法可以是：终端设备在初始化的候选传输资源集合中进行资源排除。若经过资源排除的候选传输资源集合中剩余的候选单时隙资源数量小于第二参数，和/或经过资源排除的候选传输资源集合中剩余的位于重叠区域内的传输资源数量小于第三门限，则终端设备重新初始化候选传输资源集合，在初始化的候选传输资源集合中重新进行资源排除，直到候选传输资源集合中剩余的候选单时隙资源数量大于或等于第二参数，且候选传输资源集合中剩余的位于重叠区域内的传输资源数量大于或等于第三门限。其中，第二参数可以根据第一资源选择窗内包括的总资源数量的X％确定，X例如为20，35或50。
当终端设备采用完全侦听时，第一资源选择窗内包括的总资源数量指的是第一资源选择窗内包括的所有候选单时隙资源的数量。当终端设备采用部分侦听时，第一资源选择窗内包括的总资源数量指的是在第一资源选择窗内选取的Y个时隙对应的候选单时隙资源的数量。
在一些实施方式中，第一资源选择窗的起始位置与激活期的起始位置一致或者位于激活期的起始位置之后。如果第一资源选择窗的起始位置位于激活期的起始位置之前，若候选传输资源集合中包括激活期起始位置之前的传输资源，该传输资源为无效的传输资源，因为在激活期起始位置之前，接收端处于非激活状态，无法进行侧行接收，因此，发送端也无法使用该资源进行侧行传输。
上述方法中，终端设备获取第一指示信息，第一指示信息用于指示激活期。终端设备确定第一资源选择窗和激活期的重叠区域包括的第一时隙的数量。若第一时隙的数量小于或等于第一门限，终端设备在第一资源选择窗中确定候选传输资源集合，候选传输资源集合中包括位于激活期内的传输资源。在基于SL DRX的侧行传输系统中，发送端在发送侧行数据时，选取的侧行传输资源包括位于接收端的激活期内的传输资源，接收端可以在激活期内接收发送端发送的侧行数据，解决了发送端如何确定侧行传输资源的问题。
