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。
另外，在5G系统中，还支持非授权频段(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。对于工作在非授权频段的通信系统，发送节点在发送信号之前，需要采用LBT的方式确定信道是否空闲，只有确定信道为空闲后才可以发送信号。
对于LTE系统中，基站在下行时隙中侦听到信道为空闲后，使用该空闲信道向终端设备发送上行调度授权(Uplink Grant，UL Grant)，终端设备接到该上行调度授权后也要进行侦听，如果侦听到信道为空闲，则终端设备使用该空闲信道发送上行数据。
在5G系统中，终端设备与基站之间可以通过信道状态指示参考信号(Channel State Indication Reference Signals，CSI-RS)、信道探测参考信号(Sounding Reference Signal Reference Signals，SRS)和同步信号块(Synchronizing Signal Block，SSB)等参考信号的发送与测量过程，获取一个测量结果最优的链路进行数据传输。
终端设备在一个确定的波束上进行载波侦听(或称波束侦听、信道侦听、侦听等)，如果在发送数据之前检测到该波束上的信道忙碌，则该上行数据无法发送，那么终端设备可能失去一次调度机会，该上行数据的传输将被延迟。
为了降低非授权频段上的上行信道的传输时延，本申请实施例提出，网络设备可以为终端设备配置多个候选波束用于上行信道的发送，终端设备通过依次在多个候选波束上进行载波侦听，从而基于侦听结果选择合适的波束进行上行信道的发送，大大降低了非授权频段上的上行信道的传输时延。
图2是本申请实施例的上行数据的调度方法的流程交互图。图2中所示的网络设备例如可以为图1中所示的网络设备110。图2中所示的终端设备例如可以为图1中所示的终端设备121和终端设备122。图2所示的方法可以应用在非授权频段，如图2所示，该上行数据的调度方法可以包括以下部 分或全部内容：
在210中，网络设备向终端设备发送第一信令。
在220中，终端设备接收网络设备发送的该第一信令。
其中，该第一信令包括M个波束的波束信息，M为正整数。
该第一信令例如可以为下行控制信道PDCCH，或者为无线资源控制(Radio Resource Control，RRC)信令。
可选地，该第一信令中包括的每个波束的波束信息为探测参考信号(Sounding Reference Signal，SRS)资源索引。
可选地，在220之前，该终端设备需要获取该M的值。例如，终端设备可以接收该网络设备发送的第二指示信息，该第二指示信息用于指示M的值；或者，该终端设备获取预存在该终端设备中的M的值。
也就是说，M的值可以是网络设备为终端设备配置的，或者M的值为终端设备与网络设备预先约定并预存在终端设备中的，例如协议约定的值。
在230中，该终端设备根据该第一信令，对该M个波束中的全部或部分波束进行载波侦听。
可选地，该终端设备可以根据该第一信令，依次对该M个波束进行载波侦听；或者，该终端设备可以同时对所述M个波束进行载波侦听。后面具体说明。
可选地，230中所述的对该M个波束中的全部或部分波束进行载波侦听，可以是，对该M个波束中的全部或部分波束进行方向性的载波侦听。例如，对某个波束而言，可以对该波束的第一侦听方向进行载波侦听，和/或对该波束的第二侦听方向进行载波侦听。该第一侦听方向例如为使用该波束向网络设备发送数据的方向，该第二侦听方向例如为该第一侦听方向的背向。
在240中，终端设备根据侦听结果，选择该全部或部分波束中的一个波束向该网络设备发送上行信道。
在250中，该网络设备接收该终端设备使用该M个波束中的一个波束发送的上行信道。
例如，终端设备根据在不同波束上侦听到的信道状态(忙碌或者空闲)，从该M个波束中选择一个波束，并使用该波束向网络设备发送上行信道，网络设备使用该波束接收终端设备发送的该上行信道。
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。
可选地，该上行信道为物理上行共享信道物理上行链路共享信道(Physical Uplink Shared Channel，PUSCH)或者物理上行控制信道(Physical Uplink Control Channel，PUCCH)。
在230中，终端设备对M个波束中的全部或部分波束进行载波侦听，具体可以通过以下两种方式，下面分别描述。
方式1
可选地，在230中，所述终端设备根据所述第一信令，对所述M个波束中的全部或部分进行载波侦听，包括：该终端设备根据该第一信令，依次对该M个波束进行载波侦听，直到在第N波束上侦听到信道为空闲。
其中，N为小于或等于M的正整数。
终端设备依次对该M个波束进行载波侦听时，例如可以根据该M个波束的优先级，按照优先级由高至低的顺序，依次对该M个波束进行载波侦听。
M个波束的优先级例如可以是网络设备根据每个波束上的信号测量结果例如参考信号的信号质量或者参考信号接收功率确定的，这里不做限定。
相应地，在240中，该终端设备根据侦听结果，选择该M个波束中的一个波束向该网络设备发送上行信道，包括：该终端设备使用该第N个波束，向该网络设备发送上行信道。
相应地，在250中，该网络设备接收该终端设备使用该M个波束中的一个波束发送的上行信道，包括：该网络设备接收该终端设备使用该M个波束中的第N个波束发送的上行信道。其中，该第N个波束为该终端设备依次对该M个波束进行载波侦听，直到侦听到信道为空闲时对应的波束，N为小于或等于M的正整数。
例如，终端设备从第1个波束开始始进行载波侦听，在对第1个波束至第N-1个波束的侦听中，均未侦听到空闲信道，即信道均被占用，而在第N个波束上才侦听到信道为空闲，那么终端设备可以停止对剩余波束的侦听，并使用该第N个波束发送上行信道。
终端设备侦听到第N个波束上的信道为空闲，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。
举例来说，假设M＝4，4个候选的波束分别为波束B1、波束B2、波束B3和波束B4，且优先级顺序为：波束B1＞波束B2＞波束B3＞波束B4。那么，终端设备首先在波束B1上进行载波侦听，若波束B1上没有空闲信道，则继续在波束B2上进行载波侦听。若在波束B2上侦听到信道为空闲，则停止侦听并使用波束B2向网络设备发送上行信道，若在波束B2上未侦听到空闲信道，则继续在波束B3上进行载波侦听。若在波束B3上侦听到信道为空闲，则停止侦听并使用波束B3向网络设备发送上行信道，若在波束B3上未侦听到空闲信道，则继续在波束B4上进行载波侦听。若在波束B4上侦听到信道为空闲，则使用波束B4向网络设备发送上行信道，若在波束B4上仍未侦听到空闲信道，则可以延迟该上行信道的发送。
可选地，包括该第N个波束在内的已被侦听的N个波束，与N个侦听窗口一一对应，该终端设备在该N个波束中的每个波束上进行载波侦听所使用的侦听窗口，为该每个波束对应的侦听窗口。
该终端设备在对N个波束进行侦听时，是分别在不同的侦听窗口中进行侦听的。在对每个波束进行侦听时，是在该波束对应的侦听窗口中进行的。
可选地，该N个波束对应的N个侦听窗口可以是等长或者不等长的。
可选地，该N个波束对应的N个侦听窗口在时间上连续分布。
例如，假设N＝3，终端设备在侦听到第3个波束即波束B3时侦听到信道为空闲，被侦听过的这三个波束分别为波束B1、波束B2和波束B3，优先级顺序为：波束B1＞波束B2＞波束B3。波束B1对应的侦听窗口为W1，波束B2对应的侦听窗口为W2，波束B3对应的侦听窗口为W3，这三个侦听窗口按照时间先后顺序依次为W1、W2和W3。相应地，终端设备依次在W1、W2和W3内，分别在波束B1、波束B2和波束B3上进行侦听。
可选地，在220之前，即该终端设备依次在该M个波束上进行方向性的载波侦听之前，该方法还包括：该终端设备接收该网络设备发送的第一指示信息，该第一指示信息用于指示每个侦听窗口的信息；或者，该终端设备获取预存在该终端设备中的该每个侦听窗口的信息。
其中，可选地，该每个侦听窗口的信息包括每个侦听窗口的时间长度和/或每个侦听窗口的起始时间位置。
也就是说，每个侦听窗口的长度和/或起始时间位置可以是网络设备为终端设备配置的，或者为终端设备与网络设备预先约定并预存在终端设备中的，例如协议约定该侦听窗口的长度和/或起始时间位置。
可选地，该第一信令还包括第一时长和/或第二时长的信息。
其中，该第一时长为：该网络设备向该终端设备发送的物理下行控制信道(Physical Downlink Control Channel，PDCCH)所在的时隙、起始时域符号或结束时域符号，与第一侦听窗口的起始时刻之间相隔的时长，该第一侦听窗口为该N个波束中第一个被侦听的波束对应的侦听窗口。
其中，该第二时长为：该终端设备向该网络设备发送的PUSCH所在的时隙或结束时域符号，与下行反馈信道所在的时隙或起始时域符号之间相隔的时长，该下行反馈信道用于该终端设备向网络设备发送针对该PUSCH的反馈应答信息。
下面以图3和图4为例，对第一时长和第二时长进行描述。
如图3所示，假设N＝2，终端设备在侦听到第2个波束时侦听到信道为空闲。被侦听过的这两个波束分别为波束B1和波束B2。波束B1对应的侦听窗口为W1，波束B2对应的侦听窗口为W2。网络设备向终端设备发送的PDCCH与侦听窗口W1之间的时间间隔等于第一时长T1。终端设备在接收到该PDCCH后的T1时长后，开始进行载波侦听。首先在W1内在波束B1上进行侦听，未侦听到空闲信道，其次在W2内在波束B2上进行侦听，侦听到空闲信道。从而该终端设备使用波束B2向网络设备发送PUSCH。该网络设备接收到终端设备使用波束B2发送的该PUSCH后，在T2时长后向该终端设备发送针对该PUSCH的反馈应答消息例如确认(ACKnowledgement，ACK)或否定确认(Negative ACK，NACK)消息。
又如图4所示，假设N＝3，终端设备在侦听到第3个波束时侦听到信道为空闲。被侦听过的这三个波束分别为波束B1、波束B2和波束B3。波束B1对应的侦听窗口为W1、波束B2对应的侦听窗口为W2、波束B3对应的侦听窗口为W3。网络设备向终端设备发送的PDCCH与侦听窗口W1之间的时间间隔等于第一时长T1。终端设备在接收到该PDCCH后的T1时长后，开始进行载波侦听。首先在W1内在波束B1上进行侦听，未侦听到空闲信道，其次在W2内在波束B2上进行侦听，未侦听到空闲信道，其次在W3内在波束B3上进行侦听，侦听到空闲信道。从而该终端设备使用波束B3向网络设备发送PUSCH。该网络设备接收到该终端设备使用波束B3发送的该PUSCH后，在T2时长后向该终端设备发送针对该PUSCH的反馈应答消息例如ACK消息或NACK消息。
可选地，终端设备在某个波束对应的侦听窗口内侦听到信道为空闲后，可以立即进行上行信道的发送，即，上行信道的发送可以在侦听窗口的剩余时间内发送。
例如图5所示，该终端设备在侦听窗口W1内对波束B1进行侦听，发现信道被占用，接下来该终端设备在侦听窗口W2内对波束B2进行侦听，并在W2内的某个时刻侦听到波束B2上信道为空闲，那么可以在W2内的剩余时间都可以用来传输PUSCH。
这样，通过配置较大的侦听窗口，网络设备可以确保终端设备的载波侦听与数据发送均在一个侦听窗口内完成，从而，针对一个侦听窗口，网络设备仅需要使用一个接收波束来接收该终端设备可能发送的上行数据。
反之，如果侦听窗口时长设置的较短，终端设备在侦听到信道为空闲后，需要在该侦听窗口之外发送所述上行信道，则网络可能无法确定终端设备在哪一个波束上侦听到信道为空闲，因此需要同时在多个可能的波束方向上同时接收终端设备可能发送的上行数据。这时，网络设备具有同时接收多个波束方向的上行信号的能力。
方式2
可选地，在230中，所述终端设备根据所述第一信令，对所述M个波束中的全部或部分波束进行载波侦听，包括：所述终端设备同时对所述M个波束进行载波侦听。
例如，终端设备同时打开多个或所有接收面板(pannel)以进行载波侦听。
相应地，在240中，所述终端设备根据侦听结果，选择所述全部或部分波束中的一个波束向所述网络设备发送上行信道，包括：所述终端设备使用侦听到信道为空闲的波束，向所述网络设备发送上行信道。
相应地，在250中，该网络设备接收该终端设备使用该M个波束中的一个波束发送的上行信道，包括：网络设备接收所述终端设备使用所述M个波束中侦听到信道为空闲的波束发送的上行信道，其中所述终端设备同时对所述M个波束进行载波侦听。
因此，本申请实施例中，网络设备通过为终端设备配置多个候选波束用于上行信道的发送，终端设备通过依次在多个候选波束上进行载波侦听，并基于侦听结果选择合适的波束进行上行信道的发送，从而能够大大降低非授权频段上的上行信道的传输时延。
