具体实施方式
本申请实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，简称为“GSM”)系统、码分多址(Code Division Multiple Access，简称为“CDMA”)系统、宽带码分多址(Wideband Code Division Multiple Access，简称为“WCDMA”)系统、通用分组无线业务(General Packet Radio Service，简称为“GPRS”)、长期演进(Long Term Evolution，简称为“LTE”)系统、LTE频分双工(Frequency Division Duplex，简称为“FDD”)系统、LTE时分双工(Time Division Duplex， 简称为“TDD”)、通用移动通信系统(Universal Mobile Telecommunication System，简称为“UMTS”)、全球互联微波接入(Worldwide Interoperability for Microwave Access，简称为“WiMAX”)通信系统或未来的5G系统等。
图1示出了本申请实施例应用的无线通信系统100。该无线通信系统100可以包括网络设备110。网络设备100可以是与终端设备通信的设备。网络设备100可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域内的终端设备(例如UE)进行通信。可选地，该网络设备100可以是GSM系统或CDMA系统中的基站(Base Transceiver Station，BTS)，也可以是WCDMA系统中的基站(NodeB，NB)，还可以是LTE系统中的演进型基站(Evolutional Node B，eNB或eNodeB)，或者是云无线接入网络(Cloud Radio Access Network，CRAN)中的无线控制器，或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备、未来5G网络中的网络侧设备或者未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)中的网络设备等。
该无线通信系统100还包括位于网络设备110覆盖范围内的至少一个终端设备例如终端设备121和终端设备122。终端设备121和终端设备122可以是移动的或固定的。可选地，终端设备121和终端设备122可以指接入终端、用户设备(User Equipment，UE)、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备、未来5G网络中的终端设备或者未来演进的PLMN中的终端设备等。其中，可选地，终端设备121与终端设备122之间也可以进行终端直连(Device to Device，D2D)通信。
图1示例性地示出了一个网络设备和两个终端设备，可选地，该无线通信系统100可以包括多个网络设备并且每个网络设备的覆盖范围内可以包括其它数量的终端设备，本申请实施例对此不做限定。
可选地，该无线通信系统100还可以包括网络控制器、移动管理实体等其他网络实体，本申请实施例对此不作限定。
在5G系统中，数据传输所采用的频段比LTE中使用的频段更高，因此无线信号传输的路径损耗变大，无线信号的覆盖变小。为此，5G系统中提出波束成形(beamforming)技术，以提高无线信号的增益，从而弥补路径损耗。具体地，基站向终端设备发送信号所使用的波束具有方向性，不同波束实际对应着不同的发射方向，每个窄波束只能覆盖小区的部分区域，而无法覆盖小区中的所有区域。例如图1所示，图1示出了4个不同方向的波束，即波束B1、波束B2、波束B3和波束B4，基站可以通过着4个不同方向的波束向终端设备发送信号。对于波束B1和波束B2，只能覆盖终端设备121而无法覆盖终端设备122；而波束B3和波束B4只能覆盖终端设备122而无法覆盖终端设备121。基站可以通过波束B1和波束B2向终端设备121发送信号，通过波束B3和波束B4向终端设备122发送信号。
下面简单介绍本申请实施例涉及的非授权频段(unlicensed frequency bands)上的先听后说(Listen Before Talk，LBT)机制，以及工作在非授权频段上的无线保真(Wireless Fidelity，WiFi)系统中的请求发送(Request-To-Send，RTS)/清除发送(Clear-To-Send，CTS)机制。
在5G系统中，支持非授权频段(unlicensed frequency bands)上的数据传输。在使用非授权频段进行数据传输时是基于先听后说(Listen Before Talk，LBT)机制。即，发送节点在发送数据之前，需要侦听信道是否空闲，只有确定信道为空闲后才可以发送数据。
另外，对于工作在非授权频段上的无线保真(Wireless Fidelity，WiFi)系统，为了解决隐藏节点的问题，提出了请求发送(Request-To-Send，RTS)/清除发送(Clear-To-Send，CTS)机制。隐藏终端(Hidden Stations)是指，基站A向基站B发送信号，基站C未侦测到基站A时，也可以向基站B发送，故基站A和基站C同时将信号发送至基站B，引起了信号冲突，最终可能导致发送至基站B的信号都丢失了。这时，可以通过RTS/CTS机制解决这个问题。若使用RTS/CTS时，同时设置传送上限字节数，一旦待传送的数据大于此上限值时，即启动RTS/CTS握手协议。首先，基站A向基站B发送RTS信号，表明基站A要向基站B发送若干数据，基站B收到RTS信号后发出CTS信号，表明已准备就绪，基站A可以发送数据，而其余欲向基站B发送数据的基站则暂停向基站B发送数据。这样，双方在成功交换RTS/CTS信号(即完成握手)后才开始真正的数据传递，就保证了多个 互不可见的发送节点同时向同一接收节点发送信号时，实际只能是收到接收节点回应CTS信号的那个节点能够向接收节点传输数据，从而避免了冲突。
由于发送节点只有收到接收节点返回的CTS信号时，才可以与接收节点之间传输数据。因此，如何提高发送节点和接收节点之间的信号传输效率，成为亟待解决的问题。
本申请实施例中，发送节点在向接收节点发送请求发送信号时，通过携带传输允许发送信号所使用的配置信息，使接收节点能够基于该配置信息向发送节点发送该允许发送信号，且发送节点能够基于该配置信息检测该允许发送信号，从而提高了发送节点和接收节点之间的信号传输效率。
应理解，本申请实施例中，接收一个信号所使用的波束，可以理解为，接收一个信号所使用的空间域接收滤波器(Spatial domain reception filter)；发送一个信号所使用的波束，可以理解为，发送一个信号所使用的空间域传输滤波器(Spatial domain transmission filter)。对于采用相同的空间域发送滤波器发送的两个信号，可以称这两个信号相对于空间接收参数是准同址(Quasi-Co-Located，QCL)的。
图2是本申请实施例的信号传输的方法的流程交互图。图2中所示的发送节点设和接收节点例如可以为图1中所示的网络设备110、终端设备121或终端设备122。图2所示的方法例如可以应用在非授权频段。如图2所示，该信号传输的方法可以包括以下部分或全部内容：

可选地，该配置信息包括N个候选波束的指示信息，和/或，N个候选 波束各自对应的允许发送信号的发送时间的信息，N为正整数。

该N个候选波束中每个候选波束对应的允许发送信号的发送时间例如可以包括：以假定使用该每个候选波束发送允许发送信号时所占用的时间。

其中，该目标波束例如可以为：该N个候选波束中侦听到信道为空闲的波束；或者，该N个候选波束中参考信号的测量结果最优的波束；或者，该侦听到信道为空闲的波束中参考信号的测量结果最优的波束。
终端设备在某个波束上侦听到信道为空闲，例如可以是该波束上发送的参考信号的功率小于一个预设阈值，这时认为该波束上的信道为空闲。
