Description

一种信号传输方法、相关设备及*** 技术领域
本发明涉及通信技术领域，尤其涉及一种信号传输方法、相关设备及***。
背景技术
随着无线通信技术的发展,当前的频谱资源已经难以满足用户对容量需求的***式增长。频谱资源是不可再生的自然资源，为了提升网络容量，不仅要研发多输入多输出技术、超密集组网、全双工技术等新技术，同时也要不断挖掘新的可用资源。近年来,为缓解数据流量的拥堵问题，非授权频谱受到广泛关注。从2013年到2018年，非授权频谱移动通信技术的研究历程包括非授权频谱上的长期演进(long term evolution in unlicensed spectrum，LTE-U)、许可协助接入(lisenced assisted access，LAA)、MulteFire和非授权频谱第五代移动通信新空口(the fifth generation mobile communication new radio，5G NR)。为使用非授权频段，第三代合作伙伴计划(3rd generation partnership project，3GPP)Relese13提出LAA技术，即采用载波聚合方式将5GHZ的非授权频段与授权频段进行联合使用。LAA技术提供了超越WiFi的增强版的网络容量、覆盖范围和简化的统一网络管理。LTE-U技术将长期演进(long term evolution，LTE)部署到非授权频谱，并采用标准LTE空口协议完成通信。MulteFire技术将LTE技术应用于非授权频谱，提供类似LTE的高性能通信服务以及类似Wi-Fi的简单部署。非授权频谱5G NR是基于正交频分复用(orthogonal frequency division multiplexing，OFDM)的全新空口设计的全球性标准，提高了频谱利用率，并将带来5G NR新的网络部署场景。
在MulteFire技术中，如果非授权频谱单独组网，发现信号(discovery signal，DRS)需要承载在非授权频谱上，DRS信号的发送要遵循信道接入机制。将非授权频谱无线通信技术应用于更高频的载波频谱是非授权频谱移动通信技术的发展趋势，为减少高频载波下DRS信号传输的路径损耗，可以采用波束赋形技术将DRS信号在不同的发送波束进行发送。为了增加DRS的发送机会，MulteFire技术中提出了基于发现信号测量定时配置(discovery measurement timing configuration，DMTC)的DRS信号发送。现有技术中，终端通常需要在整个DMTC窗口内进行DRS信号检测和接收，用以进行信道质量测量。在基于波束赋形技术的非授权频谱无线通信中，如何进行信号传输以降低终端的检测开销，还是有待解决的问题。
发明内容
本发明实施例提供了一种信号传输方法、相关设备及***，在基于波束赋形技术的非授权频谱无线通信中，能够降低终端的信号检测开销。
第一方面，本发明实施例提供了一种信号传输方法，应用于网络设备。该方法可包括：网络设备在第一时间段进行信道侦听。若网络设备侦听到信道为空闲状态，则网络设备在第一时间段之后的M个时间段依次发送M个发送波束的信号。网络设备配置的发送波束总数为K，K个发送波束中的第s个发送波束对应N s个时间窗，上述K个发送波束对应P 个时间窗。上述K个发送波束包括上述M个发送波束，上述M个发送波束包括上述K个发送波束中的第i个发送波束，上述M个时间段中的第二时间段位于上述第i个发送波束对应的第j个时间窗内。上述第j个时间窗为上述第i个发送波束对应的N i个时间窗中的一个时间窗。K为大于等于1的正整数，P为大于等于1的正整数，N s为小于P的正整数，N i为大于等于1且小于P的正整数，M为大于等于1且小于等于K的正整数。
实施第一方面所描述的方法，网络设备配置了K个发送波束，K个发送波束中的第i个发送波束对应了N i个时间窗，上述K个发送波束共对应了P个时间窗。网络设备侦听到信道为空闲状态后，在信道占用时间内的M个时间段依次发送M个发送波束的信号。上述M个时间段中的每个时间段对应了上述P个时间窗中的一个时间窗。网络设备仅在上述P个时间窗中的N i个时间窗内发送上述第i个发送波束的信号，N i小于P，因此第i个发送波束覆盖范围下的终端仅需要在上述N i个时间窗内进行上述第i个发送波束的信号的检测和接收，用以进行信道质量测量，采用本发明，在基于波束赋形技术的非授权频谱无线通信中，降低了终端的信号检测开销。
在一个可能的设计中，网络设备在第一时间段之后的M个时间段依次发送M个发送波束的信号之前，还包括：若侦听到信道为空闲状态，则网络设备根据配置信息从上述K个发送波束中确定上述M个发送波束，配置信息包括上述K个发送波束和上述P个时间窗的对应关系。
在一个可能的设计中，第一时间段和第二时间段相邻。
在一个可能的设计中，第一时间段与上述M个时间段中最早的时间段的时间间隔大于零且小于网络设备发送一个承载有用信息所需时间单元的时长。
在一个可能的设计中，上述P个时间窗中的第a个时间窗的起始时刻早于上述P个时间窗中的第a+1个时间窗的起始时刻，上述P个时间窗中的第a个时间窗的截止时刻晚于上述P个时间窗中的第a+1个时间窗的起始时刻，上述P个时间窗中的第a个时间窗的截止时刻早于上述P个时间窗中的第a+1个时间窗的截止时刻。

在一个可能的设计中，上述P个时间窗中的第e个时间窗的截止时刻等于上述P个时间窗中的第e+1个时间窗的起始时刻。
在一个可能的设计中，P大于等于K时，上述P个时间窗中任意连续的K个时间窗一一对应上述K个发送波束。
在一个可能的设计中，上述P个时间窗为第一窗口的时间窗，上述P个时间窗的起始时刻与第一窗口的起始时刻相同，上述P个时间窗的截止时刻与第一窗口的截止时刻相同，第一窗口为第一窗口集合中的一个窗口，第一窗口集合中的第g个窗口的起始时刻与第一窗口集合中的第g+1个窗口的起始时刻的时间间隔为第一周期。

在一个可能的设计中，第一对应关系和第二对应关系满足第一规律。第一规律为若z为小于等于P g+1–x的正整数，则上述第g个窗口中的第z个时间窗对应的发送波束与上述第g+1个窗口中第z+x个时间窗对应的发送波束相同，P g+1为上述第g+1个窗口中的时间窗个数，x为小于K的正整数；若z为大于P g+1–x且小于等于P g+1的正整数，则上述第g个窗口中的第z个时间窗对应的发送波束与上述第g+1个窗口中第z+x-P g+1个时间窗对应的发送波束相同。
在一个可能的设计中，第一对应关系和第二对应关系满足第一规律。第一规律为若P g+1+1-z大于零，则上述第g个窗口中的第z个时间窗对应的发送波束与上述第g+1个窗口中的第P g+1+1-z个时间窗对应的发送波束相同；若P g+1+1-z小于或等于零，则上述第g个窗口中的第z个时间窗对应的发送波束与上述第g+1个窗口中的第P g+1*(t+1)+1-z个时间窗对应的发送波束相同。t为使P g+1*(t+1)+1-z大于零的最小正整数，z为大于等于1小于P g的正整数，P g为第一窗口集合中第g个窗口中时间窗个数。

在上述运行环境下，本发明实施例提出了一种信号传输方法。该方法适用于MulteFire或其他使用非授权频谱的无线通信***中。图4是本发明实施例提供的信号传输方法的示意性流程图。如图4所示，本发明实施例提供的信号传输方法包括但不限于步骤S401至S404。下面对该方法实施例的可能实现方式做进一步的描述。
S401：网络设备在第一时间段进行信道侦听。
本发明实施例中信道侦听可以是预定义的某种信道侦听技术。
可选的，信道侦听可以为先听后说(listen before talk，LBT)，LBT是指需要传输数据的装置在某一无线载波上发送数据之前需要对该无线载波的无线环境进行检测，以确定是否有其它装置正在该无线载波上传输数据。信道侦听也可以称为空闲信道评估(clear channel assessment，CCA)或载波侦听(carrier sensing，CS)，统一称为信道侦听。
本发明实施例中，LBT可以为能量检测模式的LBT，如图5所示，能量检测模式的LBT是指当检测到该无线载波上的能量大于预设门限时，则认为有其它装置正在该无线载波上传输数据，该装置在该无线载波上LBT失败，该装置将避让一段时间后再尝试发送数据；当检测到该无线载波上的能量小于预设门限时，则认为该无线载波处于空闲状态，该装置在该无线载波上LBT成功，该装置在该无线载波上发送数据。本发明实施例中，LBT可以为信号检测模式的LBT，信号检测模式的LBT是指通过检测无线载波上是否有预先设计的信号来判断信道是否空闲。此外，本发明实施例中，LBT还可以为其它模式的LBT，例如，以信号功率或信噪比等因素为衡量标准的LBT。下文描述的信道处于空闲状态可以指检测到该信道上的能量小于能量门限，也可以指未检测到该信道上有预先设计的信号，在此不做限制。下文描述的无线载波不处于空闲状态可以指检测到该信道上的能量大于或等于能量门限，也可以指检测到该信道上有预先设计的信号，在此不做限制。
第三代合伙伙伴项目(3rd generation partnership project，3GPP)在LAA的研究中，评估了四种类型的LBT机制，包括：
类型1：无LBT，即设备发送数据之前不进行LBT。
类型2：不带随机退避过程的LBT，即固定时间长度的LBT。采用固定时长的帧，包括信道占用时间和空闲时间。在进行数据传输之前进行信道侦听，若信道处于空闲状态，则在随后的信道占用时间进行数据传输，否则在整个帧周期内都无法传输数据。为方便描述，下面简称Category-2LBT。
类型3：带随机退避过程的LBT，采用不固定帧周期的帧结构，并且竞争窗口长度固定。若信道处于空闲状态，数据传输可以立即开始，否则进入竞争窗口(contention Window，CW)。
类型4：带随机退避过程的LBT，采用不固定帧周期的帧结构，并且竞争窗口长度不固定。与采用固定长度竞争窗口不同的是，发送端设备可以改变CW的长度。为方便描述，下面简称Category-4LBT。
随机退避是指，若在设备检测到信道处于空闲状态后的等待时间内，该信道依然处于空闲状态，该设备才能在该信道上传输数据。该等待时间时需要在一个指定的最小值和最大值之间进行选择，最小值和最大值指定的范围就称作CW。
可选的，信道侦听可以为Category-2LBT。信道侦听也可以为Category-4LBT。
非授权频谱信道接入后，使用该信道进行信号传输的时长受最大信道占用时间(maximum channel occupancy time，MCOT)限制。Category-2LBT的MCOT较小，通常取值为1毫秒(ms)。Category-4LBT的MCOT较大，且信道接入的业务优先级越高，Category-4LBT的MCOT相对越小。
可选的，网络设备在第一时间段进行全向的信道侦听。全向的信道侦听是指网络设备在信道侦听过程中，不区分信号是从网络设备哪个接收波束的波束范围到达的，即信道侦听在全部信号到达方向上进行。
可选的，网络设备在第一时间段利用全向接收天线进行全向的信道侦听。
可选的，网络设备在第一时间段进行有向的信道侦听。有向的信道侦听是指网络设备在信道侦听过程中，仅侦听特定的接收波束范围内的信号，即网络设备可以侦听在特定的接收波束范围内是否有其他设备占用信道。
可选的，网络设备在第一时间段利用有向接收天线进行有向的信道侦听。或者，网络设备在第一时间段利用利用接收波束赋形技术进行有向的信道侦听。
可选的，网络设备在第一时间段内针对第一接收波束进行有向的信道侦听，若网络设备侦听到信道为空闲状态，则网络设备在第一时间段后的MCOT内连续发送H个发送波束的信号，第一接收波束的波束范围包含了上述H个发送波束的波束范围，H大于等于1的正整数。
举例来说，网络设备配置了16个发送波束，网络设备需要发送上述16个发送波束中的3个发送波束的信号，上述3个发送波束分别为上述16个发送波束中的第1个发送波束、第2个发送波束以及第3个发送波束。网络设备在第一时间段内针对第一接收波束进行有向的信道侦听，如图6所示，第一接收波束的波束范围包含了上述第1个发送波束的波束范围、上述第2个发送波束的波束范围以及上述第3个发送波束的波束范围。若网络设备侦听到第一接收波束的波束范围内信道为空闲状态，则网络设备在第一时间段后的MCOT 内连续发送上述第1个发送波束的信号、上述第2个发送波束的信号以及上述第3个发送波束的信号。
需要说明的是，网络设备接收波束的波束范围是指网络设备具有较高接收天线增益的信号接收方向范围。如图6所示，以水平方向的波束方向为例，假设正东方向为0度，正北方向为90度，正西方向为180度，正南方向为270度。若网络设备通过一个接收波束接收正东方向到达的信号，在称该接收波束方向为0度。若在0度的接收波束方向至60度的接收波束方向范围内，网络设备的第一接收波束的接收天线增益均大于第一预设增益值，则称第一接收波束的波束范围为0度接收波束方向至60度接收波束方向。同理可知，网络设备发送波束的波束范围是指网络设备具有较高发射天线增益的信号发送方向范围。若网络设备通过发送波束向正东方向发射信号，则称该发送波束方向为0度。若在10度的发送波束方向至50度的发送波束方向范围内，网络设备的第一发送波束的发射天线增益均大于第二预设增益值，则称第一发送波束的波束范围为10度的发送波束方向至50度的发送波束方向。此外，第一接收波束的波束范围包含第一发送波束的波束范围。例如，第一预设增益值为10dBi，第二预设增益值为10dBi。
可选的，网络设备可以具有多个信道侦听单元，用于同时针对多个不同的接收波束进行信道侦听，当侦听到上述多个不同的接收波束中的一或多个接收波束的信道为空闲状态时，网络设备可以从上述一或多个接收波束中选择一个接收波束，并且在该接收波束的波束范围内的一或多个发送波束上进行信号的发送。该接收波束的波束范围包含上述一或多个发送波束的波束范围。
可选的，上述多个不同的接收波束中的任意两个接收波束的波束范围在空间方向上可以有重叠的部分，也可以没有重叠的部分，本发明实施例对此不作具体限定。
可选的，网络设备可以具有多个信道侦听单元，用于同时针对多个不同的接收波束进行信道侦听，上述多个接收波束的中任意两个接收波束的波束范围在空间方向上可以有重叠的部分，也可以没有重叠的部分，对此不做限定。当多个接收波束中一或多个接收波束的信道侦听结果为信道空闲状态时，网络设备可以在一或多个发送波束上进行信号的发送。上述一或多个发送波束中任一发送波束的波束范围包含在上述一或多个接收波束的至少一个接收波束的波束范围中。
S402：若网络设备侦听到信道为空闲状态，则网络设备在第一时间段之后的M个时间段依次发送M个发送波束的信号。网络设备配置的发送波束总数为K，K个发送波束中的第s个发送波束对应N s个时间窗，上述K个发送波束对应P个时间窗。上述M个时间段中的第二时间段位于第i个发送波束对应的第j个时间窗内，上述第j个时间窗为上述第i个发送波束对应的N i个时间窗中的一个时间窗。
具体的，若网络设备侦听到信道为空闲状态，则网络设备在第一时间段之后的M个时间段依次发送M个发送波束的信号。网络设备配置的发送波束总数为K，上述K个发送波束对应P个时间窗。上述K个发送波束包括上述M个发送波束，上述M个发送波束包括上述K个发送波束中的第i个发送波束，上述M个时间段中的第二时间段位于上述第i个发送波束对应的第j个时间窗内。上述第j个时间窗为上述第i个发送波束对应的N i个时间窗中的一个时间窗。K为大于等于1的正整数，P为大于等于1的正整数，N s为小于P的 正整数，N i为大于等于1且小于P的正整数，M为大于等于1且小于等于K的正整数。
可以理解，K个发送波束中的第s个发送波束对应N s个时间窗，N s可以等于0，也可以大于0，即上述K个发送波束中的一个发送波束对应上述P个时间窗中的零个、一个或多个时间窗。上述P个时间窗中的一个时间窗对应上述K个发送波束中的一个发送波束，上述P个时间窗总共对应K个发送波束中的S个发送波束，S小于等于K。上述K个发送波束中的第i个发送波束对应N i个时间窗，第二时间段位于上述第i个发送波束对应的第j个时间窗内，上述N i个时间窗包括上述第j个时间窗，N i大于等于1。第i个发送波束对应的第j个时间窗表示上述P个时间窗中的第j个时间窗为用于发送第i个发送波束的信号的时间窗。
可选的，网络设备发送上述K个发送波束中的第i个发送波束的信号，该信号可以包括DRS信号、RS信号和/或SS block等。
可选的，上述K个发送波束的中任意两个发送波束的波束范围在空间方向上可以有重叠的部分，也可以没有重叠的部分，本发明实施例对此不作具体限定。
上述P个时间窗中任意两个相邻的时间窗满足以下关系：上述P个时间窗中的第h个时间窗的起始时刻早于或等于上述P个时间窗中的第h+1个时间窗的起始时刻，上述P个时间窗中的第h个时间窗的截止时刻晚于或等于上述P个时间窗中的第h+1个时间窗的起始时刻，上述P个时间窗中的第h个时间窗的截止时刻早于或等于上述P个时间窗中的第h+1个时间窗的截止时刻。上述P个时间窗中两个相邻的时间窗可以是重叠的，也可以是非重叠的。下面对上述P个时间窗中两个相邻的时间窗的可能的位置关系做进一步的描述。
本发明实施例中，上述P个时间窗中两个相邻的时间窗的位置关系包括但不限于如下四种实现方式：
(1)第一种位置关系中，上述P个时间窗中的第a个时间窗的起始时刻早于上述P个时间窗中的第a+1个时间窗的起始时刻，上述P个时间窗中的第a个时间窗的截止时刻晚于上述P个时间窗中的第a+1个时间窗的起始时刻，上述P个时间窗中的第a个时间窗的截止时刻早于上述P个时间窗中的第a+1个时间窗的截止时刻。上述P个时间窗中两个相邻的时间窗的一种可能的位置关系如图7A所示。上述P个时间窗的一种可能的位置关系如图7B所示。
(2)第二种位置关系中，上述P个时间窗中的第b个时间窗的起始时刻早于上述P个时间窗中的第b+1个时间窗的起始时刻，上述P个时间窗中的第b个时间窗的截止时刻等于上述P个时间窗中的第b+1个时间窗的截止时刻。上述P个时间窗中两个相邻的时间窗的一种可能的位置关系如图8A所示。上述P个时间窗的一种可能的位置关系如图8B所示。
(3)第三种位置关系中，上述P个时间窗中的第c个时间窗的起始时刻等于上述P个时间窗中的第c+1个时间窗的起始时刻，上述P个时间窗中的第c个时间窗的截止时刻早于上述P个时间窗中的第c+1个时间窗的截止时刻。上述P个时间窗中两个相邻的时间窗的一种可能的位置关系如图9A所示。上述P个时间窗的一种可能的位置关系如图9B所示。
(4)第四种位置关系中，上述P个时间窗中的第e个时间窗的截止时刻等于上述P个时间窗中的第e+1个时间窗的起始时刻。上述P个时间窗中两个相邻的时间窗的一种可能的位置关系如图10A所示。上述P个时间窗的一种可能的位置关系如图10B所示。
其中，第一位置关系、第二位置关系和第三位置关系中两个相邻的时间窗有重叠，第四位置关系中两个相邻的时间窗无重叠。
本发明实施例中，若上述P个时间窗中两个相邻的时间窗的位置关系为第一位置关系或第四位置关系，则上述两个相邻的时间窗的时长可以相同，也可以不同。本发明实施例对此不作具体限定。
本发明实施例中，除了如图7B、图8B、图9B或图10B所示的上述P个时间窗的位置关系，上述P个时间窗的位置关系还可以包括上述第一位置关系、第二位置关系、第三位置关系和第四位置关系中的多种位置关系的组合。例如，如图11所示，上述P个时间窗的位置关系包括第一位置关系和第四位置关系。
除了如图7B、图8B、图9B、图10B或图11所示的上述P个时间窗的位置关系，上述P个时间窗的位置关系还可以包括但不限于如下两种实现方式：
(1)第五种位置关系中，上述P个时间窗中的第a个至第a+U个连续的时间窗完全重叠。并且第a个时间窗的起始时刻早于上述P个时间窗中的第a+U+1个时间窗的起始时刻，上述P个时间窗中的第a个时间窗的截止时刻晚于上述P个时间窗中的第a+U+1个时间窗的起始时刻，上述P个时间窗中的第a个时间窗的截止时刻早于上述P个时间窗中的第a+U+1个时间窗的截止时刻。上述P个时间窗的一种可能的位置关系如图12所示。其中U为大于等于1的正整数。
(2)第六种位置关系中，上述P个时间窗中的第a个至第a+U个连续的时间窗完全重叠。并且第a个时间窗的截止时刻等于上述P个时间窗中的第a+U+1个时间窗的起始时刻。上述P个时间窗的一种可能的位置关系如图13所示。
本发明实施例中，上述P个时间窗中的每个时间窗的时长大于等于网络设备发送一个承载有用信息所需时间单元的最小时长。
可以理解，网络设备通常需要在一定大小的时频资源单元上进行信号发送。以LTE***为例，时域上，时频资源单元的大小可以以符号长度、时隙、子帧等为基本单位。例如，在LTE***中，可以选择时长约等于70微秒(us)的符号长度作为网络设备发送一个承载有用信息所需时间单元的基本单位，即网络设备发送一个承载有用信息所需时间单元的最小时长，网络设备发送一个承载有用信息的信号的起始时刻需要对齐符号的起始边界。
需要说明的是，网络设备信道侦听的结束时刻可能与下一个符号的起始边界并不对齐，这种情况下，信道侦听的结束时刻到下一个符号的起始边界之间的时间间隔小于符号长度。上述时间间隔不能用于网络设备发送一个承载有用信息的信号，为了保障该信道不被其它进行信道侦听的设备抢占，网络设备可以在上述时间间隔内传输不承载有用信息的信号，上述不承载有用信息的信号是指不需要终端进行接收的信号，且该信号仅用于占据信道，以防其他设备侦听到该信道为空闲状态。
本发明实施例中，上述P个时间窗中任意两个相邻的时间窗的发送优先级满足如下关系：上述P个时间窗中的第h个时间窗的发送优先级高于上述P个时间窗中的第h+1个时间窗。上述M个时间段中的第w个时间段对应的时间窗的发送优先级高于M个时间段中的第w+1个时间段对应的时间窗。
可选的，网络设备在上述P个时间窗内最多发送R i次上述K个发送波束中的第i个发 送波束的信号，R i为大于等于1的正整数。
可选的，若上述K个发送波束中的第i个发送波束的信号为DRS信号，则网络设备在上述P个时间窗内最多发送1次上述第i个发送波束的DRS信号。
可选的，若网络设备侦听到信道为空闲状态，网络设备在第一时间段之后的M个时间段依次发送M个发送波束的信号，上述M个发送波束的信号在上述P个时间窗内第一时间段之前均未被发送。
可选的，若网络设备在第一时间段通过Category-2LBT侦听到信道为空闲状态，则网络设备在第一时间段之后的M个时间段依次发送M个发送波束的信号，上述M个时间段中的第二时间段位于上述K个发送波束中的第i个发送波束对应的第j个时间窗内。上述M个时间段位于第一时间段之后的Category-2LBT的MCOT内，M大于等于1且小于等于K。第一时间段的截止时刻与第二时间段的的起始时刻的时间间隔可以等于零，也可以小于第一时间间隔，第一时间间隔加上述K个发送波束中的第i个发送波束的信号时长所得时长小于或等于Category-2LBT的MCOT。若上述K个发送波束中的第i个发送波束的信号为DRS信号，则在上述K个发送波束中的第i个发送波束的信号在上述P个时间窗内第一时间段之前未被发送。
可以理解，在上述第一时间段，Category-2LBT信道侦听所采用的接收波束的波束范围包含上述M个发送波束的波束范围。
例如，M等于1，上述K个发送波束中的第i个发送波束的信号时长等于0.9ms，第一时间间隔等于0.1ms，Category-2LBT的MCOT等于1ms。
可选的，若网络设备在第一时间段通过Category-4LBT侦听到信道为空闲状态，则网络设备在第一时间段之后的M个时间段依次发送M个发送波束的信号，上述M个时间段中的第二时间段位于上述K个发送波束中的第i个发送波束对应的第j个时间窗内。上述M个时间段位于第一时间段之后的Category-4LBT的MCOT内。M大于等于1且小于等于K，第一时间段的截止时刻与第二时间段的起始时刻的第一时间间隔大于零且小于网络设备发送一个承载有用信息所需时间单元的时长。若上述M个发送波束的信号为DRS信号，则上述M个发送波束的信号在上述P个时间窗内第一时间段之前均未被发送。
可以理解的，上述第一时间段Category-4LBT信道侦听所采用的接收波束的波束范围应包含上述M个发送波束的波束范围。
例如，M等于4，上述K个发送波束中的第i个发送波束的信号时长等于1ms，M个时间段依次发送M个发送波束的信号的时长为4ms，第一时间间隔等于0.3ms，Category-4LBT的MCOT等于6ms。
可选的，若第二时间段不仅位于上述K个发送波束中的第i个发送波束对应的第j个时间窗内，还位于上述K个发送波束中的第e个发送波束对应的第f个时间窗内，且上述第j个时间窗的起始时刻早于或等于上述第f个时间窗的起始时刻，上述第j个时间窗的起截止时刻早于或等于上述第f个时间窗的截止时刻，则网络设备在第二时间段内优先发送上述K个发送波束中的第i个发送波束的信号。
可以理解，网络设备在第二时间段内发送上述K个发送波束中的第i个发送波束的信号之前，网络设备在第一时间段针对第二接收波束进行信道侦听，第二接收波束的波束范 围包含上述第i个发送波束的波束范围。
举例来说，网络设备配置的发送波束总数为5，5个发送波束对应8个时间窗，网络设备在5个发送波束发送的信号均为DRS信号。如图14A所示，网络设备在DRS信号可发送点之前的第一时间段通过Category-2LBT侦听到信道为空闲状态。第一时间段后的信道占用时间段位于上述8个时间窗中的第2个时间窗和第3个时间窗内，上述第2个时间窗和第3个时间窗分别对应5个发送波束中的第2个发送波束和第3个发送波束。如图14A所示，若在第三时间段内未发送上述第2个发送波束的DRS信号，则网络设备在信道占用时间段内发送上述第2个发送波束的DRS信号。可以理解的，这种情况下网络设备在第一时间段进行的Category-2LBT信道侦听的接收波束的波束范围包含上述第2个发送波束的波束范围。若在第三时间段内发送了上述第2个发送波束的DRS信号，则网络设备在信道占用时间段内发送上述第3个发送波束的DRS信号。可以理解，这种情况下网络设备在第一时间段进行的Category-2LBT信道侦听的接收波束的波束范围包含上述第3个发送波束的波束范围。若在第三时间段内发送了上述第2个发送波束和上述第3个发送波束的DRS信号，则网络设备在信道占用时间段内不发送DRS信号。上述第三时间段表示8个时间窗内第一时间段之前的时间段。
举例来说，网络设备配置的发送波束总数为5，5个发送波束对应8个时间窗，网络设备在5个发送波束发送的信号均为DRS信号。如图14B所示，网络设备在第一时间段通过Category-4LBT侦听到信道为空闲状态。第一时间段后的信道占用时间段位于上述8个时间窗中的第2个时间窗、第3个时间窗和第4个时间窗内，上述第2个时间窗、第3个时间窗和第4个时间窗分别对应上述5个发送波束中的第2个发送波束、第3个发送波束和第4个发送波束。如图14B所示，若在第四时间段内未发送上述第2个发送波束、第3个发送波束和第4个发送波束的DRS信号，则网络设备在信道占用时间段内的Δt1、Δt2和Δt3这三个时间段内分别发送上述第2个发送波束、第3个发送波束和第4个发送波束的DRS信号。可以理解，这种情况下网络设备在第一时间段进行的Category-4LBT信道侦听的接收波束的波束范围包含上述第2个发送波束、第3个发送波束和第4个发送波束的波束范围。若在第四时间段内发送了上述第2个发送波束的DRS信号，则网络设备仅在Δt1和Δt3这两个时间段内分别发送上述第3个发送波束和第4个发送波束的DRS信号。可以理解，这种情况下网络设备在第一时间段进行的Category-4LBT信道侦听的接收波束的波束范围包含上述第3个发送波束和第4个发送波束的波束范围。若在第四时间段内发送了上述第2个发送波束和第3个发送波束的DRS信号，则网络设备仅在Δt3时间段内发送上述第4个发送波束的DRS信号。可以理解，这种情况下网络设备在第一时间段进行的Category-4LBT信道侦听的接收波束的波束范围包含上述第4个发送波束的波束范围。上述第四时间段表示8个时间窗内第一时间段之前的时间段。
举例来说，网络设备配置的发送波束总数为5，5个发送波束对应8个时间窗，网络设备在5个发送波束发送的信号均为DRS信号，DRS信号的时长为1ms。如图14C所示，8个时间窗中的每个时间窗的时长等于DRS信号时长，每个时间窗的起始点为DRS信号的可发送点，上述8个时间窗中的第3个时间窗对应上述5个发送波束中的第3个发送波束。网络设备在上述第3个时间窗之前的第一时间段通过Category-2LBT进行信道侦听， Category-2LBT的MCOT为1ms。如图14C所示，若网络设备侦听到信道为空闲状态，且第五时间段内未发送上述第3个发送波束的DRS信号，则在上述第3个时间窗内发送上述第3个发送波束的DRS信号。若网络设备侦听到信道不是空闲状态，则在上述第3个时间窗内不发送DRS信号，并在上述8个时间窗中的第4个时间窗之前的第一时间段内再次进行信道侦听。可以理解，网络设备在第一时间段进行的Category-2LBT信道侦听的接收波束的波束范围包含上述第3个发送波束的波束范围。上述第五时间段表示8个时间窗内第一时间段之前的时间段。
可选的，上述P个时间窗为第一窗口的时间窗，上述P个时间窗的起始时刻与第一窗口的起始时刻相同，上述P个时间窗的截止时刻与第一窗口的截止时刻相同，第一窗口为第一窗口集合中的一个窗口。如图15所示，第一窗口集合中的第g个窗口的起始时刻与第一窗口集合中的第g+1个窗口的起始时刻的时间间隔为第一周期。
可选的，第一窗口集合中的两个相邻的窗口的时长可以相同，也可以不同。本发明实施例对此不作具体限定。
可选的，第一窗口集合中的两个相邻的窗口内的时间窗个数可以相同，也可以不同。本发明实施例对此不作具体限定。
可选的，第一窗口为DMTC窗口。
第一窗口集合中的任意两个窗口的时长可以相同，也可以不同。第一窗口集合中的任意两个窗口中的时间窗的个数可以相同，也可以不同。本发明实施例对此均不作具体限定。
可选的，第一窗口集合中第g个窗口中的时间窗与上述K个发送波束的对应关系为第一对应关系，第一窗口集合中第g+1个窗口中的时间窗与上述K个发送波束的对应关系为第二对应关系，第一对应关系和第二对应关系可以相同，也可以不同，本发明实施例对此不作具体限定。
可选的，第一对应关系和第二对应关系不同，且第一对应关系和第二对应关系满足一定规律。下面对该规律可能的形式做进一步的描述。
本发明实施例中，第一对应关系和第二对应关系所满足的规律包括但不限于如下两种：
(1)第一种规律，若z为小于等于P g+1–x的正整数，则第一窗口集合中第g个窗口中的第z个时间窗对应的发送波束与第一窗口集合中第g+1个窗口中的第z+x个时间窗对应的发送波束相同，P g+1为第一窗口集合中第g+1个窗口中的时间窗个数，x为小于K的正整数；若z为大于P g+1-x且小于等于P g+1的正整数，则第一窗口集合中第g个窗口中的第z个时间窗对应的发送波束与第一窗口集合中第g+1个窗口中的第z+x-P g+1个时间窗对应的发送波束相同。
(2)第二种规律，若P g+1+1-z大于零，则第一窗口集合中第g个窗口中的第z个时间窗对应的发送波束与第一窗口集合中第g+1个窗口中的第P g+1+1-z个时间窗对应的发送波束相同。若P g+1+1-z小于或等于零，则第一窗口集合中第g个窗口中的第z个时间窗对应的发送波束与第一窗口集合中第g+1个窗口中的第P g+1*(t+1)+1-z个时间窗对应的发送波束相同。t为使P g+1*(t+1)+1-z大于零的最小正整数，z为大于等于1小于P g的正整数，P g为第一窗口集合中第g个窗口中时间窗个数。
举例来说，网络设备配置的发送波束总数为3，如图16A所示，第一窗口集合中第g 个窗口中的时间窗个数为6，第一窗口集合中第g+1个窗口中的时间窗个数为5。第一对应关系和第二对应关系满足上述第一种规律，x取值为2。如图16A所示，是第一对应关系和第二对应关系的一种可能的示意图。
举例来说，网络设备配置的发送波束总数为3，如图16B所示，第一窗口集合中第g个窗口中的时间窗个数为6，第一窗口集合中第g+1个窗口中的时间窗个数为5。第一对应关系和第二对应关系满足上述第二种规律。如图16B所示，是第一对应关系和第二对应关系的一种可能的示意图。
可选的，第一窗口集合中以连续的F个窗口为一个子集，第一窗口集合的子集间没有重叠，第一窗口集合中的每个子集中的所有时间窗对应了I个发送波束，I等于K。第一窗口集合中的第r个子集和第r+1个子集为相邻子集，上述第r个子集的最后一个窗口与上述第r+1个子集的第一个窗口之间没有窗口存在。第一窗口集合中每个子集的时间窗和上述K个发送波束具有对应关系，并且第一窗口集合中任意相邻两个子集的时间窗和上述K个发送波束的对应关系相同。
举例来说，网络设备配置的发送波束总数为6，如图17所示，第一窗口集合中以连续的2个窗口为一个子集，第一窗口集合中第g个窗口和第g+1个窗口组成第一子集，第一窗口集合中第g-2个窗口和第g-1个窗口组成第二子集，第一子集和第二子集为相邻子集。图17是第一窗口集合中每个子集中的时间窗和6个发送波束的一种可能的对应关系。
可选的，网络设备在第一时间段之后的M个时间段依次发送M个发送波束的信号之前，还包括：若网络设备在第一时间段侦听到信道为空闲状态，则网络设备根据配置信息从上述K个发送波束中确定上述M个发送波束，配置信息包括上述K个发送波束和上述P个时间窗的对应关系。
可以理解，配置信息可以包含第一窗口集合的周期、第一窗口集合中各窗口的起始位置和第一窗口集合中各窗口的结束位置等信息，还可以包含第一窗口集合中各窗口的时间窗的个数、各窗口中每个时间窗的起始位置、各窗口中每个时间窗的结束位置以及各窗口中每个时间窗和上述K个发送波束的对应关系。
可选的，配置信息具有更新规则。例如，配置信息中包括一个有效时间通知信息，即该配置信息只在有效时间段内有效，有效时间段之后网络设备会更新发送信号中的配置信息。
可以理解，网络设备根据配置信息获知上述P个时间窗的位置关系，以及上述P个时间窗与上述K个发送波束的对应关系。若网络设备在第一时间段侦听到信道为空闲状态，则网络设备根据配置信息获知上述M个时间段中的第y个时间段所在的Y个时间窗，以及上述Y个时间窗对应的发送波束。网络设备根据这Y个时间窗的发送优先级，从而确认上述第y个时间段发送的信号的发送波束。
举例来说，网络设备配置的发送波束总数为5，5个发送波束对应8个时间窗。网络设备根据配置信息获知上述8个时间窗的位置关系，以及上述8个时间窗与上述5个发送波束的对应关系。网络设备在第一时间段之后的第二时间段发送信号。如图18所示，第二时间段位于上述8个时间窗的第1个时间窗、第2个时间窗和第3个时间窗的重叠时间段内，上述第1个时间窗、第2个时间窗和第3个时间窗分别对应上述5个发送波束中的第2个 发送波束、第3个发送波束和第2个发送波束。上述第1个时间窗的发送优先级高于上述第2个时间窗，上述第2个时间窗的发送优先级高于上述第3个时间窗。因此，终端根据配置信息和各时间窗的发送优先级，确认在第二时间段内发送的信号的发送波束为上述第1个时间窗对应的上述第2个发送波束。
可选的，网络设备每次发送的上述K个发送波束中的第i个发送波束的信号均包含配置信息。
可选的，网络设备发送的上述K个发送波束中的第i个发送波束的信号周期性的包含配置信息。例如，网络设备发送的上述第i个发送波束的信号中，每三次中有一次包含配置信息。
可选的，网络设备发送的上述K个发送波束中的第i个发送波束的信号为DRS信号，该DRS信号包含配置信息。该配置信息可以承载在该DRS信号中的物理广播信道(physical broadcast channel，PBCH)部分。该配置信息也可以承载在该DRS信号中的物理下行控制信道(physical downlink control channel，PDCCH)部分。该配置信息也可以承载在该DRS信号中的物理下行共享信道(physical downlink sharing channel，PDSCH)部分。该配置信息还可以承载在该DRS信号中的PBCH、PDCCH和/或PDSCH中。本发明实施例对此不作具体限定。
可选的，网络设备在第二时间段内发送上述K个发送波束中的第i个发送波束的信号，该信号包含该信号的发送波束编号标识。该信号的发送波束编号标识用于表征该信号对应于上述K个发送波束中的第i个发送波束。下面对信号的发送波束编号标识可能的编码方式做进一步的描述。
本发明实施例中，信号的发送波束编号标识的编码方式包括但不限于如下两种：
(1)第一种编码方式，网络设备通过n bit二进制信息表示上述K个发送波束的信号的发送波束编号标识，n为小于等于log  2P的最大正整数。第一种编码方式下，在上述P个时间窗内每个发送波束的信号的发送波束编号标是固定不变的。
(2)第二种编码方式，第二时间段位于上述P个时间窗中的V个时间窗的重叠时间段内，上述V个时间窗对应上述K个发送波束中的W个发送波束，V大于等于1且小于等于P，W大于等于1且小于等于K。若V等于1或V大于1且W等于1，即第二时间段仅对应一个发送波束，即上述K个发送波束中的第i个发送波束，则网络设备不需要指示该信号的发送波束编号标识，终端可以根据配置信息获知第二时间段对应上述K个发送波束中的第i个发送波束。若V大于1且W大于1，即上述V个时间窗包括上述P个时间窗中的第j个时间窗，上述W个发送波束包括上述K个发送波束中的第i个发送波束，则网络设备通过m bit二进制信息表示上述W个发送波束的信号的发送波束编号标识，m为小于等于log 2W的最大正整数。第二种编码方式下，在上述P个时间窗内每个发送波束的信号的发送波束编号标是可变的。第二种编码方式适用于如下情况：网络设备发送上述K个发送波束中的第i个发送波束的信号均包含配置信息或者周期性的包含配置信息，接收端设备可以通过配置信息获知第二时间段对应的V个时间窗，以及V个时间窗对应的W个发送波束，当V或W等于1时，终端可以根据配置信息确定信号的发送波束，V大于1且W大于1时终端根据配置信息以及信号的发送波束编号标识确定信号的发送波束。
举例来说，信号的发送波束编号标识采用第一种编码方式。网络设备配置了8个发送波束，8个发送波束中第1个发送波束的信号的发送波束编号标识为000，8个发送波束中中第7个发送波束的信号的发送波束编号标识为110。
举例来说，网络设备配置了8个发送波束，8个发送波束对应10个时间窗。网络设备在第二时间段内发送8个发送波束中的第3个发送波束的信号，该信号包含该信号的发送波束编号标识和配置信息，信号的发送波束编号标识采用第二种编码方式。若第二时间段仅位于上述10个时间窗中的第6个时间窗内，网络设备不需要指示信号的发送波束编号标识。若第二时间段位于上述10个时间窗中的3个时间窗的重叠时间段内，上述3个时间窗对应于8个发送波束中的2个发送波束，即8个发送波束中的第2个发送波束和8个发送波束中的第4个发送波束。网络设备通过1bit二进制信息表示上述2个发送波束的信号的发送波束编号标识，上述第2个发送波束的信号的发送波束编号标识为0，上述第4个发送波束的信号的发送波束编号标识为1。接收端设备根据配置信息，获知第二时间段位于上述10个时间窗中的3个时间窗的重叠时间段内，以及上述3个时间窗对应的2个发送波束。若接收端接收到发送波束编号标识为1的信号，则接收端根据上述2个发送波束的顺序，判断接收到的信号为上述第4个发送波束的信号。
可选的，网络设备发送的上述K个发送波束中的第i个发送波束的信号包含配置信息，该配置信息可以携带该信号的发送波束编号标识。
可选的，信号的配置信息优先承载在PDSCH上。
可以理解，这是由于配置信息的信息量较大，需要更多的传输资源来传输配置信息，而相比于PBCH和PDCCH，PDSCH中的传输资源更多。
可选的，信号的发送波束编号标识优先承载在PBCH上。
可以理解，这是由于信号的发送波束编号标识的信息量较小，而相比于PDSCH和PDCCH，PBCH中的传输资源相对较少，且PBCH的接收复杂性相对较小。因此，若终端需要接收网络设备发送的该信号，并获取该信号的发送波束编号标识，网络设备将信号的发送波束编号标识承载在PBCH上，可以减少终端实施上述接收信号和获取发送波束编号标识的过程的复杂度。
S403：终端确定K个发送波束中第i个发送波束对应的N i个时间窗在上述P个时间窗中的位置。
可选的，终端确定上述K个发送波束中的J个发送波束对应的A个时间窗在上述P个时间窗中的位置，A个时间窗包括N i个时间窗。上述J个发送波束包括上述第i个发送波束及上述第i个发送波束的一或多个相近的发送波束。
可选的，终端确定上述K个发送波束中第i个发送波束对应的N i个时间窗在上述P个时间窗中的位置之前，还包括：终端在第一时刻接收网络设备发送的上述K个发送波束中的第i个发送波束的信号，该信号中包含配置信息和该信号的发送波束编号标识；终端对该信号进行解析，获取配置信息和该信号的发送波束编号标识；终端根据该信号的发送波束编号标识获知该信号的发送波束为上述K个发送波束中的第i个发送波束。第一时刻早于上述P个时间窗的起始时刻，配置信息包括上述P个时间窗和上述K个发送波束的对应关系。
举例来说，网络设备配置的发送波束的总数为8，终端在第一时刻接收网络设备发送的8个发送波束中的第6个发送波束的DRS信号，该DRS信号中包含配置信息和该信号的发送波束编号标识；终端对该DRS信号中的PBCH、PDCCH和/或PDSCH进行解析，获取配置信息和该信号的发送波束编号标识；终端根据该信号的发送波束编号标识获知该信号的发送波束为8个发送波束中的第6个发送波束。
可选的，终端在第一时刻接收的信号包含该信号的发送波束编号标识，终端根据该信号的发送波束编号标识获知该信号的发送波束。
可选的，第一时刻后终端根据配置信息，确定在上述P个时间窗内存在上述N i个时间窗对应于上述K个发送波束中的第i个发送波束，并根据配置信息确定上述K个发送波束中的第i个发送波束对应的N i个时间窗在上述P个时间窗中的位置。
可选的，第一时刻后终端根据配置信息确定在上述P个时间窗内存在上述A个时间窗对应于上述J个发送波束，并根据配置信息确定上述J个发送波束对应的A个时间窗在上述P个时间窗中的位置。
可以理解，在获取配置信息之前，为了在第一时刻接收到网络设备发送的信号，终端需要在可能存在网络设备提供通信服务的多个载波频点中进行切换，并在切换后的载波频点持续尝试接收携带配置信息的信号。终端在第一时刻接收到携带配置信息的信号后，通过信号解析获取配置信息和该信号的发送波束。由于该配置信息中包含了第一窗口集合中各窗口的位置关系、上述各窗口中的各时间窗的位置关系以及上述各窗口中的各时间窗与上述K个发送波束的对应关系，因此，在第一时刻后终端可以根据该配置信息确定该终端所需的发送波束对应的时间窗在每个窗口中的位置。
S404：在上述N i个时间窗内，终端检测并接收网络设备发送的上述K个发送波束中的第i个发送波束的信号。
可选的，在上述A个时间窗内，终端检测并接收网络设备发送的上述K个发送波束中的J个发送波束的信号，上述J个发送波束包括上述第i个发送波束及上述第i个发送波束的一或多个相近的发送波束。
可选的，在上述N i个时间窗内，终端检测并接收网络设备发送的上述K个发送波束中的第i个发送波束的信号，以及进行信道质量测量。
可选的，在上述A个时间窗内，终端检测并接收网络设备发送的上述J个发送波束的信号，以及进行信道质量测量。
可选的，在上述P个时间窗内，终端最多仅需检测并接收到一次网络设备发送的上述K个发送波束中第i个发送波束的信号。
可以理解，在上述N i个时间窗内的第二时刻，若终端检测并接收到网络设备发送的上述K个发送波束中的第i个发送波束的信号，则在上述N i个时间窗内第二时刻后终端停止检测网络设备发送的上述第i个发送波束的信号。
可选的，在上述P个时间窗内，终端仅需检测并接收到一次上述J个发送波束中的发送波束的信号。
可以理解，在上述N i个时间窗内的第二时刻，若终端检测并接收到网络设备发送的上J个发送波束中的发送波束的信号，则在上述N i个时间窗内第二时刻后终端停止检测网络 设备发送的上述J个发送波束的信号。
可选的，在上述P个时间窗内，针对上述J个发送波束中的任意一个发送波束的信号，终端最多仅需检测并接收到一次。
可以理解，在上述A个时间窗内的第三时刻，若终端检测并接收到网络设备发送的上述J个发送波束中的一个发送波束的信号，例如，上述K个发送波束中的第i+1个发送波束的信号，上述J个发送波束包括上述第i+1个发送波束，则终端在上述A个时间窗内第三时刻后停止检测网络设备发送的上述第i+1个发送波束信号。但是终端将继续检测并接收网络设备发送的上述J个发送波束中其他发送波束的信号，例如，上述K个发送波束中的第i个发送波束的信号。
可选的，在上述P个时间窗内，终端可以多次检测并接收到网络设备发送的上述K个发送波束中的第i个发送波束的信号。
可以理解，在上述N i个时间窗内的第二时刻，若终端检测并接收到网络设备发送的上述K个发送波束中的第i个发送波束的信号，则终端在上述N i个时间窗内第二时刻后继续检测并接收上述第i个发送波束的信号。
可选的，在上述P个时间窗内，终端可以多次检测并接收到网络设备发送的上述J个发送波束的信号。
可以理解，在上述A个时间窗内的第三时刻，若终端检测并接收到网络设备发送的上述J个发送波束中的一个发送波束的信号，例如，上述K个发送波束中的第i+1个发送波束的信号，则终端在上述A个时间窗内第三时刻后继续检测并接收网络设备发送的上述第i+1个发送波束信号。
可选的，终端在上述N i个时间窗中的第二时间段接收到网络设备发送的信号，该信号包括该信号的发送波束编号标识，该信号的发送波束编号标识的编码方式为第一种编码方式，终端根据该信号的发送波束编号标识获知该信号为上述K个发送波束中的第i个发送波束的信号。
举例来说，网络设备配置的波束的个数为8，终端在上述N i个时间窗内接收到的信号的发送波束编号标识为111，该信号的发送波束编号标识的编码方式为第一种编码方式，则终端根据该信号的发送波束编号标识获知该信号为8个发送波束中的第8个发送波束的信号。
可选的，终端在上述N i个时间窗中的第二时间段内接收到网络设备发送的信号，该信号包括该信号的发送波束编号标识和配置信息，该信号的发送波束编号标识的编码方式为第二种编码方式。终端根据配置信息获知第二时间段对应的V个时间窗，以及V个时间窗对应的W个发送波束。然后，终端根据上述W个发送波束和该信号的发送波束编号标识获知该信号的发送波束。
可以理解，上述配置信息可以是终端在第二时间段之前获取的，即终端在第二时间段之前接收到网络设备发送的包含该配置信息的信号。上述配置信息也可以是终端在第二时间段内获取的，即终端在第二时间段内接收到的网络设备发送的信号包含该配置信息。
举例来说，网络设备配置的发送波束的个数为8，终端根据配置信息获知第二时间段位于3个时间窗的重叠时间段内，并且还获知上述3个时间窗对应3个发送波束，即8个 发送波束中的第2个发送波束、第4个发送波束和第5个发送波束。该信号的发送波束编号标识的编码方式为第二种编码方式。若终端在上述N i个时间窗中的第二时间段内接收到的信号的发送波束编号标识为00，则该信号为上述第2个发送波束的信号。若终端在上述N i个时间窗中的第二时间段内接收到的信号的发送波束编号标识为01，则该信号为上述第4个发送波束的信号。若终端在上述N i个时间窗中的第二时间段内接收到的信号的发送波束编号标识为10，则该信号为上述第5个发送波束的信号。
可以理解，上述N i个时间窗位于第一窗口集合中的一个窗口中。在第一窗口集合的不同窗口中，终端均可以检测并接收上述K个发送波束中的第i个发送波束的信号，并且终端在一个窗口中是否检测并接收上述第i个发送波束的信号不会影响终端在另一个窗口中对上述第i个发送波束的信号的检测和接收。
实施本发明实施例所提供的方法，网络设备配置了K个发送波束，K个发送波束中的第s个发送波束对应N s个时间窗，K个发送波束对应P个时间窗，N s为小于P的正整数。网络设备侦听到信道为空闲状态后，在信道占用时间内的M个时间段依次发送M个发送波束的信号。M个时间段中的每个时间段对应了P个时间窗中的一个时间窗。网络设备仅在上述P个时间窗中的N i个时间窗内发送第i个发送波束的信号，N i为大于等于1且小于P的正整数。因此，终端仅需要确定其所需发送波束对应的时间窗在上述P个时间窗中的位置，并仅在终端所需发送波束对应的时间窗内进行信号检测和接收，用于信道质量测量，采用本发明，在基于波束赋形技术的非授权频谱无线通信中，降低了终端的信号检测开销。
