可选地，在本申请实施例中，高层参数或高层信令包括无线资源控制RRC信令和媒体接入控制单元MAC CE中的至少一种。
非授权频谱是国家和地区划分的可用于无线电设备通信的频谱，该频谱通常被认为是共享频谱，即不同通信系统中的通信设备只要满足国家或地区在该频谱上设置的法规要求，就可以使用该频谱，不需要向政府申请专有的频谱授权。
为了让使用非授权频谱进行无线通信的各个通信系统在该频谱上能够友好共存，一些国家或地区 规定了使用非授权频谱必须满足的法规要求。例如，通信设备遵循“先侦听后传输(Listen Before Talk，LBT)”原则，即通信设备在非授权频谱的信道上进行信号发送前，需要先进行信道侦听，只有当信道侦听结果为信道空闲时，该通信设备才能进行信号发送；如果通信设备在非授权频谱的信道上的信道侦听结果为信道忙，该通信设备不能进行信号发送。为了保证公平性，在一次传输中，通信设备使用非授权频谱的信道进行信号传输的时长不能超过最大信道占用时间(Maximum Channel Occupancy Time，MCOT)。
在非授权频谱上，网络设备在发送下行信道或下行信号前需要先进行LBT，只有LBT成功才能传输，LBT失败不能传输。因此，非授权频谱上的通信是机会性传输。从系统的布网角度，信道检测包括两种机制，一种是基于负载的设备(Load based equipment，LBE)的LBT，也称为动态信道检测、动态信道接入或动态信道占用，另一种是基于帧结构的设备(Frame based equipment，FBE)的LBT，也称为半静态信道检测、半静态信道接入或半静态信道占用。
在FBE的信道接入机制，或者说，半静态信道接入模式中，帧结构是周期出现的，即通信设备可以用于业务发送的信道资源是周期性出现的。在一个帧结构内包括固定帧周期(Fixed Frame Period，FFP)、信道占用时间(Channel Occupancy Time，COT)、空闲周期(Idle Period，IP)。其中，FFP的长度取值范围可为例如1到10ms，信道占用时间COT的长度不超过固定帧周期FFP长度的95％，空闲周期IP的长度至少为固定帧周期FFP长度的5％且IP的最小值为100μs，且位于固定帧周期FFP的尾部。
通信设备在空闲周期内对信道做信道检测以评估信道的可用性(sensing for evaluating a channel availability，也称为空闲信道评估CCA)，如果信道检测成功，下一个固定帧周期内的信道占用时间(Channel Occupancy Time，COT)可以用于传输信号；如果信道检测失败，下一个固定帧周期内的信道占用时间不能用于传输信号。
目前在NR-U系统中，在FBE模式下只支持网络设备发起的COT。半静态信道接入模式可以是基站通过系统信息块(System Information Block，SIB)1指示的或通过高层参数配置的。其中，参考图2，固定帧周期(Fixed Frame Period，FFP)的长度T x可以是基站配置的，T x的单位为ms，T x取值范围可包括例如：1，2，2.5，4，5，10。其中，从每两个连续的无线帧开始，在每两个连续的无线帧内，根据x·T x确定FFP的起始位置，其中，x∈{0,1,…,20/T x-1}，FFP内的最大COT长度为T y＝0.95·T x，FFP内的空闲周期长度至少为T z＝max(0.05·T x，100μs)。
如果一个服务小区被配置为半静态信道接入模式，那么该服务小区的周期信道占用长度为T x，该服务小区的周期信道占用长度中包括的最大信道占用长度为T y，该服务小区的周期信道占用长度中包括的空闲周期的长度为T z。终端设备可以根据被配置的T x确定T y和/或T z。例如，如上所述，终端设备在确定FFP的长度T x后，可以根据预设规则确定FFP的起始位置，FFP的周期，FFP内用于信号传输的最大COT长度，FFP内用于信道检测的空闲周期等信息。
在现有的NR-U系统中，如果系统是FBE模式，那么不允许终端设备发起COT。如果终端设备想进行上行传输，则终端设备只能共享基站的COT。终端设备的信道检测方式为在16微秒或25微秒的检测时隙信道内进行长度为9微秒的能量检测，并在能量检测通过后进行传输。或者，如果终端设备的上行传输的起始位置与基站的下行传输的结束位置之间的空隙小于或等于16微秒时，终端设备可能不做信道检测直接进行上行传输。具体地，在FBE模式下，当终端设备被调度进行物理上行共享信道(Physical Uplink Shared Channel，PUSCH)或物理上行控制信道(Physical Uplink Control Channel，PUCCH)的传输时，网络设备可以通过携带上行授权(UL grant)或下行授权(DL grant)的下行控制信息(Downlink Control Information，DCI)来指示该PUSCH或PUCCH对应的信道监听方式以及终端设备待传输的延迟循环前缀的大小。
在NR-U系统中，目前考虑在FBE模式下支持终端设备发起的COT。在这种情况下，如何进行信号/信道的传输，以保证网络设备发起的COT和终端设备发起的COT在非授权频谱上的合理共存，是本申请主要考虑的问题。
基于上述问题，本申请提出了一种终端设备发起(initiate)COT的方案，可以使网络设备发起的COT和终端设备发起的COT在非授权频谱上能够合理共存，提升通信性能。
以下通过具体实施例详述本申请的技术方案。
