Description

边链路信道接入方式的确定方法、电子设备和存储介质 技术领域
本申请涉及一种无线通信技术领域，尤其涉及一种边链路信道接入方式的确定方法、电子设备和存储介质。
背景技术
目前第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)版本18(Release-18，R18)立项了边链路(SideLink，SL)在非授权频谱上通信被称为SL-U，但是非授权频谱上可以存在其他设备，诸如，新空口在非授权频谱(New Radioin Unlicensed Spectrum，NR-U)系统设备、无线保真(WIreless Fidelity，WIFI)系统设备、蓝牙系统设备等。SL-U设备在传输之前需要进行信道先听后发(Listen Before Talk，LBT)，在确定信道空闲时才可以发射信号，从而避免系统内或系统间的通信干扰。通常3GPP系统在非授权频谱上的LBT方式包括两种，即基于负载的设备(Load Based Equipment)和基于帧的设备(Frame Based Equipment，FBE)。其中的LBE通常使用的信道接入方式包括两类：第一信道接入方式(type1)和第二信道接入方式(type2)。其中，第一信道接入方式需要在传输前完成一段时间的信道监听，当信道在该段时间内持续空闲时，可以认为第一信道接入方式成功，设备可以接下来发射信道/信号；而第二信道接入方式适用于一些特殊的信号传输，或信道占用时间(Channel Occupancy Time，COT)内的信号传输，其中，COT指设备使用第一信道接入方式成功接入信道之后，则认为设备初始化了一个COT，在COT内的传输则可以不再使用信道监听时间比较长的第一信道接入方式。SL-U系统可以采用第一信道接入方式以及第二信道接入方进行信道接入，但是由于SL-U中存在没有基站调度或者有基站调度但是基站工作在授权频谱，无法协助用户设备(User Equipment，UE)进行侦听或占用信道，导致现有的SL UE信道接入成功率较低。

    所述第一节点统计的信道忙率不满足门限值，所述第一信号的定信道接入方式为第一信道接入方式。
  19. 根据权利要求18所述方法，其中，所述信道忙率包括以下至少之一：
    所述信道忙率的频域统计范围为边链路资源池频域范围；
    所述信道忙率的频域统计范围为所述第一信号所在资源块集的频域范围；
    所述信道忙率的时域统计范围为配置，预配置或者预定的一个时间窗口内的有效时隙；
    所述信道忙率的时域统计范围为配置，预配置或者预定的一个时间窗口内的有效符号。
  20. 根据权利要求18所述方法，其中，所述信道忙率的统计包括以下至少之一：
    在统计时间窗内的时域资源和频域资源上统计能量大于门限的时隙数目与所述统计时间窗内总时隙数目的比值；
    在统计时间窗内的时域资源和频域资源上统计能量大于门限的符号数目与所述统计时间窗内总符号数目的比值；
    在统计时间窗内时域资源上的目标能量中大于门限的时隙数目与所述统计时间窗内总时隙数目的比值，其中，所述目标能量为所述统计时间窗内非第三代合作伙伴计划3GPP系统信道/信号占据的能量。
  21. 根据权利要求12所述方法，其中，所述根据所述第一信息确定所述第一信号的信道接入方式，包括：
    所述第一信号的传输时间位于所述第一节点的第一信号之前的所述第二节点的第二信号的信道占用时间内，且所述第一节点不共享所述信道占用时间，所述第一信号的信道接入方式为第一信道接入方式，且所述第二信号的传输不影响所述第一节点的第一信道接入方式的信道侦听的计数器递减。
  22. 一种电子设备，包括：
    至少一个处理器；
    存储器，设置为存储至少一个程序；当所述至少一个程序被所述至少一个处理器执行，使得所述至少一个处理器实现如权利要求1-21中任一所述方法。
  23. 一种计算机可读存储介质，其上存储有计算机程序，其中，所述计算机程序被处理器执行时实现如权利要求1-21中任一所述方法。
