下面详细描述本公开的实施例，实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的要素。下面通过参考附图描述的实施例是示例性的，旨在用于解释本公开，而不能理解为对本公开的限制。
为了更好的理解本公开实施例公开的一种多无线接入技术侧行链路通信共存方法，下面首先对本公开实施例适用的通信系统进行描述。
请参见图1，图1为本公开实施例提供的一种通信系统的架构示意图。该通信系统可包括但不限于一个网络侧设备和一个终端设备，图1所示的设备数量和形态仅用于举例并不构成对本公开实施例的限定，实际应用中可以包括两个或两个以上的网络侧设备，两个或两个以上的终端设备。图1所示的通信系统以包括一个网络侧设备101和一个终端设备102为例。
需要说明的是，本公开实施例的技术方案可以应用于各种通信系统。例如：长期演进(long term evolution，LTE)系统、第五代(5th generation，5G)移动通信系统、5G新空口(new radio，NR)系统，或者其他未来的新型移动通信系统等。还需要说明的是，本申请实施例中的侧行链路(sidelink)还可以称为侧链路或直通链路。
本公开实施例中的网络侧设备101是网络侧的一种用于发射或接收信号的实体。例如，网络侧设备101可以为演进型基站(evolved NodeB，eNB)、传输点(transmission reception point，TRP)、NR系统中的下一代基站(next generation NodeB，gNB)、其他未来移动通信系统中的基站或无线保真(wireless fidelity，WiFi)系统中的接入节点等。本公开的实施例对网络侧设备所采用的具体技术和具体设备形态不做限定。本公开实施例提供的网络侧设备可以是由集中单元(central unit，CU)与分布式单元(distributed unit，DU)组成的，其中，CU也可以称为控制单元(control unit)，采用CU-DU的结构可以将网络侧设备，例如基站的协议层拆分开，部分协议层的功能放在CU集中控制，剩下部分或全部协议层的功能分布在DU中，由CU集中控制DU。
本公开实施例中的终端设备102是用户侧的一种用于接收或发射信号的实体，如手机。终端设备也可以称为终端设备(terminal)、用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端设备(mobile terminal，MT)等。终端设备可以是具备通信功能的汽车、智能汽车、手机(mobile phone)、穿戴式设备、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端设备、无人驾驶(self-driving)中的无线终端设备、远程手术(remote medical surgery)中的无线终端设备、智能电网(smart grid)中的无线终端设备、运输安全(transportation safety)中的无线终端设备、智慧城市(smart city)中的无线终端设备、智慧家庭(smart home)中的无线终端设备等等。本公开的实施例对终端设备所采用的具体技术和具体设备形态不做限定。
可以理解，在侧行链路通信中，存在NR sidelink通信和LTE sidelink通信。其中，NR sidelink和LTE sidelink之间互不兼容，NR sidelink接收机无法发送或接收LTE sidelink信号，LTE sidelink接收机也无法发送或接收NR sidelink信号。而无论NR sidelink还是LTE sidelink都需要通过资源预留和检测来减少干扰。如果两者无法获取对方的资源预留信息，两者之间将无法避免选择相同的时频资源，造成传输资 源碰撞，导致传输的可靠性降低。同时由于LTE sidelink是先发技术，所以不可能对LTE sidelink进行增强以支持动态资源共享。本公开通过LTE sidelink通信进行信道监听，获取LTE sidelink的资源预留信息，从而使通过NR sidelink进行通信的UE能够避让LTE sidelink通信所需的时频资源。
可以理解的是，本公开实施例描述的通信系统是为了更加清楚的说明本公开实施例的技术方案，并不构成对于本公开实施例提供的技术方案的限定，本领域普通技术人员可知，随着系统架构的演变和新业务场景的出现，本公开实施例提供的技术方案对于类似的技术问题，同样适用。
下面结合附图对本公开所提供的多无线接入技术侧行链路通信共存方法及其装置进行详细地介绍。
请参见图2，图2是本公开实施例提供的一种确定多无线接入技术侧行链路通信共存方法的流程示意图。该方法由第二无线接入技术侧行链路通信的终端设备执行。如图2所示，该方法可以包括但不限于如下步骤：
步骤S201，对第一无线接入技术侧行链路通信进行信道监听。
其中，在本公开的实施例中，第一无线接入技术为LTE无线接入技术；第二无线接入技术为NR无线通信技术。
步骤S202，根据第一无线接入技术侧行链路通信的信道监听结果，执行第二无线接入技术侧行链路通信的流程；
其中，在本公开的实施例中，上述流程包括如下至少一项流程：资源选择或资源重新选择；侧行链路物理信道发送；待传输资源的重评估(re-evaluation)；待传输资源的占用评估(preemption)；确定用户间协助(inter-UE coordination)信息中包含的辅助资源集合信息。
举例而言，终端设备根据LTE sidelink通信的信道监听结果，确定执行NR sidelink通信的一个或多个流程的具体实现方式。
在本公开的实施例中，终端设备执行NR sidelink通信的各个流程的具体实现方式，可采用本公开各实施例中的任一种方式实现，本公开实施例并不对此作出限定。
通过实施本公开实施例，终端设备可以根据对第一无线接入技术侧行链路通信的信道监听结果，执行第二无线接入技术侧行链路通信的流程，从而实现第二无线接入技术侧行链路通信对第一无线接入技术侧行链路通信的资源预留的避让，避免造成传输资源碰撞，实现第一无线接入技术侧行链路和第二无线接入技术侧行链路对同一载频上的传输资源动态共享，增加传输资源使用效率。
可选地，在本公开的一些实施例中，对第一无线接入技术侧行链路通信进行信道监听，包括以下至少一项：接收第一无线接入技术侧行链路通信的侧行链路物理控制信道PSCCH(physical sidelinkcontrol channel)；确定第一无线接入技术侧行链路通信的PSCCH中的侧行链路控制信息SCI(sidelinkcontrol information)所对应的侧行链路参考信号接收功率S-RSRP(sidelink-reference signal receiving power)和/或侧行链路接收信号强度指示符S-RSSI(sidelink-received signal strength indicator)测量值。
作为一种示例，终端设备对LTE sidelink通信进行信道监听，以接收该LTE sidelink通信的侧行链路物理控制信道PSCCH。
作为另一种示例，终端设备对LTE sidelink通信进行信道监听，以确定该LTE sidelink通信的PSCCH中的SCI所对应的S-RSRP测量值。
作为又一种示例，终端设备对LTE sidelink通信进行信道监听，以确定该LTE sidelink通信的PSCCH 中的SCI所对应的S-RSSI测量值。
作为又一种示例，终端设备对LTE sidelink通信进行信道监听，以接收该LTE sidelink通信的侧行链路物理控制信道PSCCH，并确定该LTE sidelink通信的PSCCH中的SCI所对应的S-RSRP测量值。
作为又一种示例，终端设备对LTE sidelink通信进行信道监听，以接收该LTE sidelink通信的侧行链路物理控制信道PSCCH，并确定该LTE sidelink通信的PSCCH中的SCI所对应的S-RSSI测量值。
作为又一种示例，终端设备对LTE sidelink通信进行信道监听，以接收该LTE sidelink通信的侧行链路物理控制信道PSCCH，并确定该LTE sidelink通信的PSCCH中的SCI所对应的S-RSRP测量值和S-RSSI测量值。
需要说明的是，在本公开的一些实施例中，在第一无线接入技术侧行链路通信的资源池与第二无线接入技术侧行链路通信的资源池存在时间域重合或时间频率资源的重合部分，可对第一无线接入技术侧行链路通信的资源池中进行信道监听。其中，第一无线技术侧行链路通信的资源池包含进行第一无线技术侧行通信的时间频率资源；第二无线技术侧行链路通信的资源池包含进行第二无线技术侧行通信的时间频率资源。
举例而言，以第一无线接入技术为LTE无线接入技术，第二无线接入技术为NR无线接入技术为例，在LTE sidelink通信的资源池中的时间频率资源，与NRsidelink通信的资源池中的时间频率资源存在时间域重合或时间频率重合部分时，终端设备在LTE sidelink通信的资源池中包含的时间频率资源对应的时间和频谱上，进行信道监听。
在本公开的一种实现方式中，第二无线接入技术侧行链路通信的流程可以为资源选择或资源重新选择。终端设备可根据LTE sidelink通信的信道监听结果，进行NR sidelink通信的资源选择或者资源重新选择。作为一种示例，请参见图3，图3是本公开实施例提供的另一种确定多无线接入技术侧行链路通信共存方法的流程示意图。该方法由第二无线接入技术侧行链路通信的终端设备执行。如图3所示，该方法可以包括但不限于如下步骤：
步骤S301，对第一无线接入技术侧行链路通信进行信道监听。
在本公开的实施例中，步骤S301可分别采用本公开的各实施例中的任一种方式实现，本公开实施例并不对此作出限定，也不再赘述。
步骤S302，进行第二无线接入技术侧行链路通信的资源选择或者资源重新选择时，根据第一无线接入技术侧行链路通信的信道监听结果，在第二无线接入技术侧行链路通信的候选资源集合中排除候选资源。
在一种可选地实现方式中，终端设备可根据第一无线接入技术侧行链路通信的信道监听结果，确定信道监听中接收到的第一无线接入技术侧行链路通信的SCI中指示或预留的时频资源；将与SCI中指示或预留的时频资源存在重合部分的候选资源，从第二无线接入技术侧行链路通信的候选资源集合中排除。
作为一种示例，终端设备根据对LTE sidelink通信信道的监听结果，确定该LTE sidelink通信的SCI中指示的需要占用的时频资源，并从NR sidelink的候选时频资源集合中，排除与上述时频资源重合的时频资源。
作为另一种示例，终端设备根据对LTE sidelink通信信道的监听结果，确定该LTE sidelink通信预留的时频资源，并从NR sidelink的候选时频资源集合中，排除与上述时频资源重合的时频资源。
可选地，将与SCI中指示或预留的时频资源存在重合部分的候选资源，从第二无线接入技术侧行链路通信的候选资源集合中排除，包括：确定与SCI相关联的S-RSRP和/或S-RSSI测量值；从第二无线接入技术侧行链路通信的候选资源集合中排除第一候选资源，其中，第一候选资源为与SCI中指示或预留的时频资源存在重合部分，且与SCI相关联的S-RSRP和/或S-RSSI测量值大于或等于第一阈值的候选资源。
作为一种示例，终端设备根据对LTE sidelink通信信道的监听结果，确定该LTE sidelink通信的SCI中指示或预留的时频资源，并确定与该LTE sidelink通信的SCI相关联的S-RSRP测量值，当上述时频资源与NR sidelink通信的候选资源集合存在重合部分，且上述S-RSRP测量值大于或等于第一阈值时，从NR sidelink通信的候选资源集合，排除与上述时频资源重合的时频资源。
作为另一种示例，终端设备根据对LTE sidelink通信信道的监听结果，确定该LTE sidelink通信的SCI中指示或预留的时频资源，并确定与该LTE sidelink通信的SCI相关联的S-RSSI测量值，当上述时频资源与NR sidelink通信的候选资源集合存在重合部分，且上述S-RSSI测量值大于或等于第一阈值时，从NR sidelink通信的候选资源集合，排除与上述时频资源重合的时频资源。
作为又一种示例，终端设备根据对LTE sidelink通信信道的监听结果，确定该LTE sidelink通信的SCI中指示或预留的时频资源，并确定与该LTE sidelink通信的SCI相关联的S-RSRP测量值和S-RSSI测量值，当上述时频资源与NR sidelink通信的候选资源集合存在重合部分，且上述S-RSRP测量值大于或等于第一阈值、S-RSSI测量值大于或等于第一阈值时，从NR sidelink通信的候选资源集合，排除与上述时频资源重合的时频资源。
可选地，第一阈值与SCI指示的第一无线接入技术侧行链路通信的优先级和第二无线接入技术侧行链路通信的优先级，存在映射关系；和/或，第一阈值与第二阈值独立配置或预配置，其中，第二阈值为根据第二无线接入技术侧行链路通信的信道监听结果进行候选资源排除时所使用的阈值。
其中，在本公开的实施例中，根据NR sidelink通信的信道监听结果进行候选资源排除的具体实现方式，与本公开实施例中根据LTE sidelink通信的信道监听结果，在NR sidelink通信的候选资源集合中排除候选资源的实现方式相同，本公开并不对此作出限定，也不再赘述。
作为一种示例，根据信道的信道状态信息设置第一阈值，第一阈值需要保证功率大于或等于该第一阈值的信号能够正常使用该信道进行通信，并且，第一阈值需要小于根据NR sidelink通信的信道监听结果进行候选资源排除时所使用的第二阈值，从而保证LTE sidelink通信的优先级大于或等于NR sidelink通信。
作为另一种示例，第一阈值需要保证功率大于或等于该第一阈值的信号能够正常使用该信道进行通信，并且，第一阈值需要小于根据NR sidelink通信的信道监听结果进行候选资源排除时所使用的第二阈值，可根据信道的信道状态信息和上述关系，对第一阈值和第二阈值进行独立配置或预配置。
作为又一种示例，可根据实际情况对第一阈值和第二阈值进行独立配置或预配置。
可以理解的是，使用信道进行正常通信所需的条件越低，则满足该条件的概率就越大，由此可见，在使用LTEsidelink通信和NR sidelink通信在同一信道进行通信时，上述两种通信方式对应的阈值的大小，反映了使用不同通信方式在该信道进行通信的难度。通信方式对应的阈值越小，则使用该通信方式进行通信的难度也就越低。在本公开的实施例中，通过配置使第一阈值小于第二阈值，从而使终端设备使用同一信道进行通信时，使用NR sidelink通信方式的难度，高于使用LTE sidelink通信，从而保 证了使用同一信道进行通信时，LTEsidelink通信的优先级高于NRsidelink通信。
通过实施本公开实施例，终端设备可以根据对LTE sidelink通信的信道监听结果，在NR sidelink通信的候选资源集合中排除候选资源，从而实现NR sidelink通信对LTE sidelink通信的避让，避免造成传输资源碰撞，实现LTE sidelink和NR sidelink对同一载频上的传输资源动态共享，增加传输资源使用效率。
在本公开的一种实现方式中，NR sidelink通信的流程可以为侧行链路物理信道发送。终端设备可根据LTE sidelink通信的信道监听结果，确定是否发送NR sidelink通信的侧行链路物理信道。作为一种示例，请参见图4，图4是本公开实施例提供的一种确定多无线接入技术侧行链路通信共存方法的流程示意图。该方法由第二无线接入技术侧行链路通信的终端设备执行。如图4所示，该方法可以包括但不限于如下步骤：
步骤S401，对第一无线接入技术侧行链路通信进行信道监听。
在本公开的实施例中，步骤S401可分别采用本公开的各实施例中的任一种方式实现，本公开实施例并不对此作出限定，也不再赘述。
步骤S402，进行第二无线接入技术侧行链路通信的侧行链路物理信道发送时，根据第一无线接入技术侧行链路通信的信道监听结果，确定是否发送第二无线接入技术侧行链路通信的侧行链路物理信道。
在一种可选地实现方式中，终端设备可根据第一无线接入技术侧行链路通信的信道监听结果，确定信道监听中接收到的第一无线接入技术侧行链路通信的SCI中指示或预留的时频资源；取消第二无线接入技术侧行链路通信的侧行链路物理信道的发送，其中，SCI中指示或预留的时频资源与第二无线接入技术侧行链路通信的待发送侧行链路物理信道所使用的时频资源存在资源重合；或者，发送第二无线接入技术侧行链路通信的侧行链路物理信道，其中，SCI中指示或预留的时频资源与第二无线接入技术侧行链路通信的待发送侧行链路物理信道所使用的时频资源未存在资源重合。
作为一种示例，终端设备根据对LTE sidelink通信的信道监听结果，确定接收到的该LTE sidelink通信SCI中指示的需要占用的时频资源，当该时频资源与NR sidelink的待发送sidelink信道所使用的时频资源存在资源重合时，则取消在该NR sidelink通信的sidelink信道的发送。
作为另一种示例，终端设备根据对LTE sidelink通信的信道监听结果，确定接收到的该LTE sidelink通信需要预留的时频资源，当该时频资源与NR sidelink的待发送sidelink信道所使用的时频资源未存在资源重合时，则进行在该NR sidelink通信的sidelink信道的发送。
可选地，终端设备根据第一无线接入技术侧行链路通信的信道监听结果，确定是否发送第二无线接入技术侧行链路通信的侧行链路物理信道，还包括：确定与SCI相关联的S-RSRP和/或S-RSSI测量值；其中，SCI中指示或预留的时频资源与第二无线接入技术侧行链路通信的待发送侧行链路物理信道所使用的时频资源存在资源重合，且与SCI相关联的S-RSRP和/或S-RSSI测量值大于或等于第三阈值，取消第二无线接入技术侧行链路通信的侧行链路物理信道的发送；或者，SCI中指示或预留的时频资源与第二无线接入技术侧行链路通信的待发送侧行链路物理信道所使用的时频资源未存在资源重合，和/或，与SCI相关联的S-RSRP和/或S-RSSI测量值小于第三阈值，发送第二无线接入技术侧行链路通信的侧行链路物理信道。
作为一种示例，终端设备根据对LTE sidelink通信信道的监听结果，确定该LTE sidelink通信的SCI 中指示或预留的时频资源，并确定与该LTE sidelink通信的SCI相关联的S-RSRP测量值，当上述时频资源与NR sidelink的待发送sidelink信道所使用的时频资源存在资源重合，且上述S-RSRP测量值大于或等于预设的第三阈值时，取消在该NR sidelink通信的sidelink信道的发送。
