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(也称为共享频谱)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(也称为信道检测)，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、半静态信道占用或周期信道占用。
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。
图2是本申请提供的一种半静态信道占用的示意性图。
如图2所示，固定帧周期(Fixed Frame Period，FFP)的长度为T x，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，可以根据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长度可以为T y＝0.95·T x，FFP内的空闲周期长度可以至少为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(或称为信道占用周期)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，可以根据预设的规则确定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。
在基于FBE的NR-U系统中，当UE被调度在基站的FFP内进行上行传输时，UE可以以共享网络设备的COT的方式进行传输。
下面对共享网络设备的COT的方案进行介绍。
当UE在COT内检测到基站发送的下行传输机会后，UE可以共享基站的该COT内的资源进行上行传输机会的发送。在这种情况下，UE的信道检测方式包括：
1.如果上行传输机会和该下行传输机会之间的空隙不超过16微秒，则UE可以在该下行传输机会结束后不做信道检测而开始发送该上行传输机会；
2.如果上行传输机会和该下行传输机会之间的空隙超过16微秒，则UE在该上行传输机会开始前的长度为25微秒的间隔内进行一个检测时隙长度为9微秒的信道检测，并在信道检测成功后发送该上行传输机会。
具体地，在FBE模式下，当终端设备被调度进行PUSCH或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DCI中的信道接入指示信息来指示该PUSCH或PUCCH对应的信道接入方式以及UE传输时的延长循环前缀(cyclic prefix extension，CPE)的大小。
在本申请的一些实施例中，携带上行授权(UL grant)或下行授权(DL grant)的下行控制信息DCI可以包括以下几种：
调度PUSCH传输的非回退上行授权(例如DCI格式0_1)：
可选的，高层参数配置第一指示集合，第一指示集合中包括至少一项联合编码的信道接入类型，CPE长度和CAPC。
可选的，该非回退上行授权中包括信道接入指示信息，该信道接入指示信息用于从上述第一指示集合中确定联合编码的信道接入类型，CPE长度和CAPC。
可选的，该信道接入类型，CPE长度和CAPC可用于PUSCH传输。
可选的，这种情况下，信道接入指示信息最多包括6比特。
调度PDSCH传输的非回退下行授权(例如DCI格式1_1)：
可选的，高层参数配置第二指示集合，第二指示集合中包括至少一项联合编码的信道接入类型和CPE长度。
可选的，该非回退下行授权中包括信道接入指示信息，该信道接入指示信息用于从上述第二指示集合中确定联合编码的信道接入类型和CPE长度。
可选的，该信道接入类型和CPE长度可用于PUCCH传输，其中，该PUCCH可以承载该非回退下行授权调度的PDSCH对应的HARQ-ACK信息。可选地，CAPC＝1。
可选的，这种情况下，信道接入指示信息最多包括4比特。
调度PUSCH传输的回退上行授权(例如DCI格式0_0)：
可选的，该回退上行授权中包括信道接入指示信息，该信道接入指示信息用于从第三指示集合中确定联合编码的信道接入类型和CPE长度。
可选的，第三指示集合是预设的，如下表1和表2所示。
可选的，该信道接入类型和CPE长度可用于PUSCH传输。可选地，终端设备根据业务优先级自行选择CAPC。
可选的，这种情况下，信道接入指示信息包括2比特。
调度PDSCH传输的回退下行授权(例如DCI格式1_0)：
可选的，该回退下行授权中包括信道接入指示信息，该信道接入指示信息用于从第三指示集合中确定联合编码的信道接入类型和CPE长度。
可选的，第三指示集合是预设的，如下表1和表2所示。
可选的，该信道接入类型和CPE长度可用于PUCCH传输，其中，该PUCCH可以承载该回退下行授权调度的PDSCH对应的HARQ-ACK信息。可选地，CAPC＝1。
可选的，这种情况下，信道接入指示信息包括2比特。

0 类型2C(Type2C) 2
1 类型2A(Type2A) 3
2 类型2A(Type2A) 1
3 类型1(Type1) 0
如表1所示，若信道接入指示信息指示0，则信道接入类型为类型2C(Type2C)，CPE长度根据表2中的CPE长度对应2的情况确定，即CPE长度根据C2和16微秒+T TA确定。可选地，CPE长度根据表2确定包括：CPE长度＝Ci*符号长度-Δi。作为示例，该情况下，CPE长度为C2*符号长度-16微秒-T TA。在该情况下可以认为CPE长度对应16微秒。
表2 CPE的参数
CPE长度 Ci Δi
0 - -
1 C1 25微秒
2 C2 16微秒+T TA
3 C3 25微秒+T TA
其中，C2和C3的取值是高层参数配置的，C1的取值是预设的，C1＝1 forμ∈{0,1},C1＝2 forμ＝2。其中，μ表示子载波间隔配置，μ＝0、1和2分别表示15kHz、30kHz和60kHz。
作为示例，在基于FBE模式下的系统中，如果终端设备收到指示Type2A信道接入或收到指示Type1信道接入的信道接入指示信息时，终端设备的信道检测方式为：终端设备在上行传输机会开始前的长度为25微秒的间隔内进行一个检测时隙长度为9微秒的信道检测。
随着系统的演进，FBE模式下也允许终端设备发起COT。
例如，终端设备发起COT的信道检测方式包括：
终端设备在上行传输机会或FFP开始前进行一个检测时隙长度为9微秒的信道检测，并在信道检 测成功后从COT的起始位置开始发送上行传输机会。如果信道检测失败，则终端设备在当前上行传输机会中不能进行任何上行传输。
然而，此这种情况下，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，是一个亟待解决的问题。
例如，当终端设备被调度上行传输，其中上行传输位于终端设备被配置的用于该终端设备发起信道占用的周期信道占用(FFP配置)中的一个信道占用(一个FFP)的起始位置时，终端设备如何确定该上行传输对应的LBT方式，例如，终端设备是以共享网络设备的COT的方式进行LBT还是以终端设备以发起COT的方式进行LBT，是本申请主要考虑的问题。
本申请提供了一种无线通信方法、终端设备和网络设备，能够使得网络设备发起的COT和终端设备发起的COT在非授权频谱上能够合理共存，以提升系统性能。
为便于对本申请的理解，下面对本申请涉及的术语进行说明。
最大信道占用时间(MCOT)：指在共享频谱的信道上信道检测(channel sensing)成功后允许使用该信道进行信号传输的最大时间长度。
信道占用时间(Channel Occupancy Time，COT)：指在共享频谱的信道上信道检测成功后使用该信道进行信号传输的时间长度，也可以认为是在共享频谱的信道上信道检测成功后占用该信道的时间长度。其中，该时间长度内信号占用信道可以是连续的或不连续的，该时间长度包括发起信道占用的设备和共享信道占用的设备进行信号传输的总时间。
网络设备的信道占用时间(gNB/eNB-initiated COT)：也称为网络设备发起的COT或网络设备发起的信道占用，指网络设备在共享频谱的信道上信道检测成功后获得的一次信道占用时间。网络设备发起的COT内除了可以用于网络设备进行传输，也可以在满足一定条件下用于终端设备进行传输。
终端设备的信道占用时间(UE-initiated COT)：也称为终端设备发起的COT或终端设备发起的信道占用，指终端设备在共享频谱的信道上信道检测成功后获得的一次信道占用时间。终端设备发起的COT内除了可以用于终端设备进行传输，也可以在满足一定条件下用于网络设备进行传输。
下行传输机会(DL transmission burst)：网络设备进行的一组下行传输(即包括一个或多个下行传输)，该组下行传输为连续传输(即多个下行传输之间没有空隙)，或该组下行传输中有空隙但空隙小于或等于16μs。如果网络设备进行的两个下行传输之间的空隙大于16μs，那么认为该两个下行传输属于两次下行传输机会。
上行传输机会(UL transmission burst)：一个终端设备进行的一组上行传输(即包括一个或多个上行传输)，该组上行传输为连续传输(即多个上行传输之间没有空隙)，或该组上行传输中有空隙但空隙小于或等于16μs。如果该终端设备进行的两个上行传输之间的空隙大于16μs，那么认为该两个上行传输属于两次上行传输机会。
信道检测成功：也称为信道检测空闲。例如对信道进行的检测时隙内的能量检测低于能量检测门限。
信道检测失败：也称为信道检测忙碌。例如对信道进行的检测时隙内的能量检测高于或等于能量检测门限。
图2示出了根据本申请实施例的无线通信方法200的示意性流程图，所述方法200可以由终端设备执行。例如，图1所示的终端设备。

换言之，如果终端设备被网络设备配置了第一周期信道占用，该第一周期信道占用用于终端设备发起COT。在这种情况下，当终端设备被调度从该第一周期信道占用中第一信道占用的起始位置开始传输第一上行传输时，需要确定是使用共享网络设备的COT的方式进行LBT还是使用终端设备发起COT的方式进行LBT。
基于以上技术方案，终端设备确定第一周期信道占用后，可以确定第一上行传输对应的信道接入方式，相当于，终端设备可确定该第一上行传输对应的LBT方式，例如UE以共享网络设备的COT的方式进行LBT或以发起COT的方式进行LBT，从而可以避免网络设备发起的COT和终端设备发起的COT在非授权频谱上发生冲突，即能够使得网络设备发起的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。
