具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
应理解，本发明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，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution， LTE)系统、先进的长期演进(Advanced long term evolution，LTE-A)系统、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、新空口(New Radio，NR)等。
还应理解，在本发明实施例中，用户设备(User Equipment，UE)包括但不限于移动台(Mobile Station，MS)、移动终端(Mobile Terminal)、移动电话(Mobile Telephone)、手机(handset)及便携设备(portable equipment)等，该用户设备可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，例如，用户设备可以是移动电话(或称为“蜂窝”电话)、具有无线通信功能的计算机等，用户设备还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置。
在本发明实施例中，基站(例如，接入点)可以是指接入网中在空中接口上通过一个或多个扇区与无线终端通信的设备。基站可用于将收到的空中帧与IP分组进行相互转换，作为无线终端与接入网的其余部分之间的路由器，其中接入网的其余部分可包括网际协议(IP)网络。基站还可协调对空中接口的属性管理。例如，基站可以是GSM或CDMA中的基站(Base Transceiver Station，BTS)，也可以是TD-SCDMA或WCDMA中的基站(NodeB)，还可以是LTE中的演进型基站(eNodeB或eNB或e-NodeB，evolutional Node B)，或者是5G NR中的基站(gNB)，本发明并不限定。
本申请实施例提供了信号传输方法及装置，用以实现触发式参考信号的传输，从而使得终端可以快速利用参考信号进行相应操作，并且降低终端功耗，达到省电效果。
随着无线通信系统的发展，终端类型和业务类型多样化，终端省电、节约网络资源和满足各种业务类型的需求并存。为了同时保证终端省电和业务可达，引入一种唤醒信号(wakeup signal，WUS)，终端监听WUS时消耗的电量相对比较低，当收到自身的WUS时，终端被WUS唤醒，再启动通信模块(电量消耗相对高)，以接收寻呼消息(paging)，或接收物理下行控制信道(Physical Downlink Control Channel，PDCCH)，或进行RRM测量，或接收同步消息，以此来达到终端的省电的目的。
如何在引入唤醒信号的基础上,进行RRM测量和信道测量,获得省电效果。
在UE接收WUS被唤醒之后，需要首先进行同步或者时频跟踪，以便于UE可以快速的进行数据的接收，从而进一步降低能耗。另一方面，UE在接收WUS被唤醒之后，在数据接收期间，希望能进行更多的操作，例如，本区和邻区的RRM测量，从而进一步降低能耗。考虑一种可能的方案，就是引入触发式参考信号(On-demand reference signal，on-demand RS)，该信号主要特点在于，on-demand RS可以是非周期的，也可是预定义周期模式(pattern)的，本申请实施例描述如何发送on-demand RS和相应的时序步骤，并讨论如何和WUS进行结合。
wakeup signal(唤醒信号)介绍如下：当终端处于空闲态时，进入一种极低电量的睡 眠状态，当网络侧有下行数据要发送给UE时，向该UE发送唤醒信号，UE收到唤醒信号后被唤醒，开始与网络侧进行数据收发。当数据收发完成后，UE再次进入极低电量的睡眠状态。类似的，当终端处于连接态时，在空闲(inactive)态时，进入一种极低电量的睡眠状态，当有下行数据需要UE接收时，则向该UE发送唤醒信号，UE收到唤醒信号后被唤醒，开始与网络进行数据收发。从而，进一步达到UE节电的目的。
本申请实施例提供的技术方案中，当UE处于节能配置状态下，基站可以通过WUS触发on-demand RS的发送以及UE的接收，从而UE可以利用on-demand RS进行快速的同步和RRM测量。其中，所述节能配置状态，是指UE配置为省电状态，或节能状态，例如，UE可以通过接收WUS而唤醒，从而接收数据，在UE没有收到WUS时，则UE一直处于睡眠状态。
本申请实施例中，将这种在WUS之后传输的RS，称为on-demand RS，相比现有技术中RS的传输方式，本申请实施例提供的RS的传输方式，可以使得UE利用RS进行快速的同步和RRM测量。
具体实现方式例如：
基站侧：一种信号发送方法包括：
步骤一：基站在以第一时间为起点的第一时间窗口内发送WUS信号；UE可以通过接收WUS而被唤醒，从而接收数据，在UE没有收到WUS时，则UE一直处于睡眠状态，从而达到节电的目的。所述第一时间窗口是大于等于零的实数。若窗口大小为零，即对应的是某一个时刻。
步骤二：基站在以第二时间为起点的第二时间窗口内发送on-demand RS信号；第二时间大于(即晚于)或等于第一时间；
所述第二时间窗口是大于等于零的实数。若窗口大小为零，即对应的是某一个时刻。
步骤三：基站在以第三时间为起点的第三时间窗口内发送PDCCH，或物理下行业务信道，或除了on-demand RS之外的物理下行参考信号(例如CRS、CSI-RS、TRS、PBCH、PSS、SSS、SS/PBCH等)。
第三时间可以大于等于第二时间；或者，第三时间小于等于第二时间且大于第一时间。
参见图1，WUS、on-demand RS、PDCCH有这样的逻辑关系：WUS触发on-demand RS发送，从而使得UE快速的同步或是RRM测量；再者，WUS发送的目的，是UE后续有数据信息需要处理，例如PDSCH，而PDSCH的接收，又需要先接收PDCCH获得调度信息后，才能接收PDSCH。
对于第三时间可以大于等于第二时间，是针对on-demand RS没有预定义模式(pattern)，可以在任意时隙(slot)或符号边界发送的情况下；此时on-demand RS可以用来进行快速的同步和RRM测量；其中，pattern是指在时间上的on-demand RS的发送图样，传输on-demand  RS所采用的pattern，具体可以根据实际需要而定。
对于第三时间小于等于第二时间，是针对on-demand RS pattern预定义的情况(即on-demand RS按照固定的周期，或是时间图样进行发送，到了发送的时刻是否发送，要看是否有WUS)下，如果在WUS发送完成后，以及UE完成数据接收，进入睡眠状态之前的一个时间窗口内，预定义的on-demand RS pattern到来的情况，即UE先接收PDCCH，后接收on-demand RS；此时，on-demand RS的主要作用是辅助RRM测量，例如在空闲态(RRC-Idle)下，如果在RRC-connected下，DCI可以触发CSI-RS发送，从而是辅助RRM测量，此时可以不额外配置on-demand RS。
参见图2和图3，on-demand RS，可以是在第二时间窗口内以burst发送的参考信号，所述burst发送，即发送的on-demand时间上包括至少一个OFDM符号，例如on-demand RS在发送时，占用多个OFDM符号，这些多个OFDM符号可以是连续发送的，也可以是不连续发送的，可以占用一个时隙(slot)，也可以占用不同的时隙。
其中，图2所示的WUS是周期性的发送的，而图3所示的WUS是非周期性的，随时有可能发的，所以，图3的时间窗口之间是非均匀间隔的。
图2和图3给出来的是on-demand RS的时间窗口，即第二时间窗口，第一时间窗口可以参考图1，将图1所示的WUS对应的箭头的时间位置扩展一下，即为第一时间窗口。
上述步骤一，是一种通过唤醒信号隐式触发参考信号on-demand RS传输的方式，即网络侧发送了唤醒信号给终端唤醒终端后，终端就要接收网络侧发送的参考信号on-demand RS。
本申请实施例中还可以有一种通过唤醒信号显示触发参考信号on-demand RS传输的方式，即：基站向终端发送用于唤醒该终端的唤醒信号，以及网络侧是否发送参考信号的指示信息。其中，所述指示信息包含在所述唤醒信号中，例如通过1比特指示位指示是否发送on-demand RS；或者，所述指示信息包含在用于加扰所述唤醒信号的序列中。
也就是说，唤醒信号可以携带有网络侧是否发送参考信号on-demand RS的指示信息，使得终端收到该唤醒信号后，通过解读该唤醒信号，可以获取该指示信息，从而决定是否接收网络侧发送的参考信号on-demand RS。若该指示信息指示了网络侧发送参考信号on-demand RS，则接收网络侧发送的参考信号on-demand RS；否则，不接收网络侧发送的参考信号on-demand RS。
相应地，若唤醒信号携带的指示信息指示了网络侧发送参考信号on-demand RS，则网络侧的基站发送参考信号on-demand RS，否则，不发参考信号on-demand RS。
相应地，在终端侧，提供的一种信号接收方法包括：
步骤一：UE在以第一时间为起点的第一时间窗口内接收第一WUS信号；
步骤二：UE在以第二时间为起点的第二时间窗口内接收第一on-demand RS信号；
同理，第二时间大于等于第一时间；所述第二时间窗口是大于等于零的实数；
步骤三：UE在以第三时间为起点的第三时间窗口内接收PDCCH；
同理，第三时间可以大于等于第二时间；或者，第三时间小于等于第二时间且大于第一时间；
具体说明：
参见图4，对于第三时间可以大于等于第二时间，是针对on-demand RS没有预定义pattern，可以在任意slot或符号边界接收的情况下；此时on-demand RS可以用来进行快速的同步和RRM测量；
对于第三时间小于等于第二时间，是针对on-demand RS pattern预定义的情况下，如果在WUS接收完成后，以及UE完成数据接收，进入睡眠状态之前的一个时间窗口内，预定义的on-demand RS pattern到来的情况；此时，on-demand RS的主要作用是辅助RRM测量，例如在RRC-Idle下。如果在RRC-connected下，DCI可以触发CSI-RS发送，从而是辅助RRM测量，此时可以不额外配置on-demand RS。
参见图5和图6，on-demand RS，可以是在第二时间窗口内以burst发送的参考信号，所述burst发送，即发送的on-demand时间上包括至少一个OFDM符号，例如on-demand RS在发送时，占用多个OFDM符号，这些多个OFDM符号可以是连续发送的，也可以是不连续发送的，可以占用一个时隙(slot)，也可以占用不同的时隙。
其中，图5所示的WUS是周期性的发送的，而图6所示的WUS是非周期性的，随时有可能发的，所以，图6的时间窗口之间是非均匀间隔的。
图5和图6给出来的是on-demand RS的时间窗口，即第二时间窗口，第一时间窗口可以参考图4，将图4所示的WUS对应的箭头的时间位置扩展一下，即为第一时间窗口。
考虑到UE可以收到多个基站的WUS和on-demand RS，因此还可以进一步包括下列步骤四和步骤五。
步骤四：UE可以在以第四时间为起点的第四时间窗口内接收第二WUS信号(第二WUS与第一WUS信号来自不同基站或不同小区)；
步骤五：UE可以在以第五时间为起点的第五时间窗口内接收第二on-demand RS信号(第二on-demand RS信号与第一on-demand RS信号来自不同基站或不同小区)；
第五时间大于等于第四时间；第四时间大于等于第二时间；所述第四时间窗口、第五时间窗口均为大于等于零的实数。
参见图7和图8，具体说明：
UE除了接收服务小区或是服务wakeup area的WUS之外，考虑RRM测量的需求，还需要对相邻小区或相邻wakeup area的WUS或on-demand RS进行测量；
邻区的WUS接收，可以发生在UE已经接收了服务小区的WUS且被唤醒之后，即第四 时间晚于第一时间；但是可以在PDCCH接收之前，也可以在PDCCH接收之后。
邻区的on-demand RS接收，可以发生在UE接收了邻区的WUS之后，即第五时间晚于第四时间，但是可以在PDCCH接收的之前，也可以在PDCCH接收之后。
也就是说，关于步骤四和步骤五，当UE收到多个WUS信号时，可能需要触发多个ON-DEMAND RS，此时，WUS和on-demand RS的时间关系保持不变，即WUS先发，而后on-demand RS发送，而多个WUS，多个on-demand RS发送时，不同的WUS和on-demand RS是可以在时间上交叠的。
本申请实施例中所提到的时间窗口，主要取决于两个因素:设备的处理能力和发送的时间先后的关系。例如，WUS触发on-demand RS发送，则on-demand RS的时间窗口一定不能延伸到WUS接收时间之前。而WUS的时间窗口可以延伸到on-demand RS的接收时刻。
同理，终端侧的另一种信号接收方法包括：
接收网络侧发送的唤醒信号，唤醒终端；以及，获取网络侧是否发送参考信号的指示信息；
根据所述指示信息确定是否接收参考信号。
其中，终端可以从所述唤醒信号中获取所述指示信息，或者，从解扰所述唤醒信号的序列中获取所述指示信息。
