具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
为了便于理解，首先介绍本公开涉及的术语。
1、先听后说(listen-before-talk，LBT)
先听后说(listen-before-talk，LBT),顾名思义叫“先听后说”或者叫“先听后发”，是无线电通信中使用较为广泛的一种技术，无线电发射机在开始传输之前首先会侦听其无线电环境，检测信道是否空闲，若信道处于繁忙状态则等待信道空闲时再传输，避免信道访问冲突，实现信道频谱共享。
2、部分带宽(bandwidth part，BWP)
部分带宽(bandwidth part，BWP)，是总带宽的一个子集带宽，其通过NR中的带宽自适应灵活调整终端设备接收和发送带宽大小，使得终端设备接收和发送带宽不需要与小区的带宽一样大。
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设备11和一个终端设备12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。
本公开实施例中的网络设备11是网络侧的一种用于发射或接收信号的实体。例如，网络设备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12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。
在通信系统中，针对高频段来说，比如，60GHz，可以采用非常窄的波束进行收发。那么进行全向LBT监听没有意义，因为不在传输方向上的LBT情况对传输没有影响，只要传输方向上信道空闲即可。为此，可以引入定向(directional)LBT，也即LBT不是全向监测，而仅在特定方向上进行监测。终端设备发送波束跟监听LBT的监测(sensing)波束之前可能有如下一些关系：一个发送波束可以对应一个sensing波束或sensing波束集，或者，一个sensing波束对应一个发送波束或发送波束集，且一个发送波束映射的sensing波束或sensing波束集的波束宽度必须至少覆盖发送波束。
此时，终端设备在一次LBT失败后，因为可能只是当前的上行发送波束有LBT问题，终端设备可以首先尝试切换发送波束，等所有波束都发生持续LBT失败时才触发BWP的持续LBT失败。这带来的问题是终端设备不知道有多少波束，所以难以判断是否所有波束都发生了持续LBT失败。所以本公开，可以设置触发BWP的持续LBT失败的条件，终端设备仅在确定满足该条件时，才触发BWP的持续LBT失败。比如，可以配置触发BWP的持续LBT失败的波束集或者预设波束，从而终端设备可以基于预设的波束集中的波束或者预设波束对应的LBT检测结果，确定是否触发BWP发生持续LBT失败，从而，可以提高确定BWP发生持续LBT失败的准确性和可靠性。下面结合附图对本公开所提供的一种位置信息的确定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先听后说失败的方法的流程示意图，该方法由终端设备执行。如图2所示，该方法可以包括但不限于如下步骤：
步骤201，在确定带宽部分BWP对应的先听后说LBT检测结果满足预设的条件的情况下，确定BWP发生持续LBT失败。
其中，预设的条件可以是通过协议约定的，或者是预先设置在系统中的，本公开对此不作限制。
本公开中，终端设备的媒体接入控制层(media access control，MAC)在对BWP进行LBT检测的过程中，可以接收到物理层(physical layer,PHY)指示的LBT失败实例。由此，终端设备即可根据接收到的LBT失败实例的情况，确定当前BWP对应的LBT检测结果。比如，当在预设的时间段内未接收到LBT失败实例时，可以确定当前BWP对应的LBT检测成功，从而可以利用此BWP对应的信道进行数据传输。当在预设的时间段内接收到LBT失败实例时，可以对LBT检测结果进行统计，在统计结果满足预设的条件的情况下，可以确定BWP发生持续LBT失败，从而可以确定当前BWP对应的信道属于空闲状态。
本公开中，终端设备在在确定带宽部分BWP对应的先听后说LBT检测结果满足预设的条件的情况下，确定BWP发生持续LBT失败。由此，终端设备可以准确的判断BWP发生持续LBT失败，从而可以提高确定BWP发生持续LBT失败的准确性和可靠性，进而可以提高切换BWP的合理性，避免资源的浪费。
请参见图3，图3是本公开实施例提供的一种确定先听后说失败的方法的流程示意图，该方法由终端设备执行。如图3所示，该方法可以包括但不限于如下步骤：
步骤301，确定BWP对应的LBT失败实例对应的波束标识。
其中，波束标识可以为波束身份标识号(identity document，ID)，等任一可以唯一确定波束的信息。
本公开中，终端设备在对服务小区的激活BWP进行LBT检测时，当PHY层监听到任一波束LBT失败时，即会将LBT失败实例发送给MAC层，从而MAC层即可基于LBT失败实例，确定LBT失败对应的波束标识。
步骤302，在波束标识为预设波束的标识的情况下，将LBT计数值加1。
其中，预设波束可以是由网络设备配置的，或者协议约定的。比如，预设波束，可以为网络设备通过物理上行链路控制信道(physical uplink control channel，PUCCH)或者上行共享物理信道(physical uplink share cHannel,PUSCH)等方式为终端设备配置的；或者，还可以将与发送波束集对应的检测波束作为预设波束；或者，还可以将与当前激活的发送波束集对应的检测波束，确定为预设波束。本方案对此不作限制。
