背景技术
唤醒信号(wake-up signal，WUS)配置于不连续接收持续时间(DRX On Duration)之前，用于指示用户设备(user equipment，UE)在接下来的一个或多个不连续接收周期(DRX cycle)是否需要唤醒UE监听物理下行控制信道(physical downlink control channel，PDCCH)。当配置了WUS时，如果WUS指示UE不唤醒，或者UE未检测到WUS从而确定不唤醒，则UE不启动DRX持续时间定时器(drx-onDurationTimer)。如果基站连续多个WUS都指示不唤醒UE，则UE在连续多个DRX周期都不启动DRX持续时间定时器，从而未进入DRX激活时间(active time)，因此，UE会长时间未被唤醒，可能造成上行链路中断。

具体实施方式
下面结合附图，对本申请的实施例进行描述。
无线电资源控制(radio resource control，RRC)连接态可能会配置不连续接收，即C-DRX(Connected-Discontinuous Reception)，其目的是为了使UE每隔一定的周期进入DRX On Duration去收发数据，而在其他时候可以进入睡眠状态，不去监听PDCCH，从而节省UE功耗。所述睡眠状态即可以认为是UE不监听PDCCH的状态。当配置DRX时，UE的状态可以分为DRX激活(DRX Active)态和DRX非激活(DRX non-active)态，UE处于DRX Active态的时间称为DRX Active Time。当UE处于DRX Active Time，UE会持续监听PDCCH。如果UE离开DRX Active Time，即进入睡眠状态(即DRX non-active态)，则UE不去监听PDCCH。
当以下任意一个定时器在运行时，UE即处于DRX Active态，这些定时器包括：DRX 持续时间定时器(drx-onDurationTimer)，DRX非激活定时器(drx-InactivityTimer)，DRX下行重传定时器(drx-RetransmissionTimerDL)，DRX上行重传定时器(drx-RetransmissionTimerUL)，随机接入竞争解决定时器(ra-ContentionResolutionTimer)。此外，DRX Active Time还包括其他情况，例如：UE在物理上行控制信道(physical uplink control channel，PUCCH)上发送了调度请求(scheduling request，SR)之后的等待时间；UE在成功接收到基于非竞争(non-contention based)随机接入的随机接入响应(random access response，RAR)之后还未收到指示新传的PDCCH的等待时间。
图1表示配置了DRX周期之后的UE状态示例。C-DRX机制举例如下：在C-DRX周期的开始时刻会首先进入DRX On Duration，同时开启drx-onDurationTimer，如果在DRX ON Duration期间UE收到PDCCH指示下行或上行新的数据传输，则会开启(或重启)drx-InactivityTimer。UE将一直处于DRX-Active态直到drx-InactivityTimer超时，或者UE收到相关的媒体接入控制控制元素(medium access control control element，MAC CE)信令使该drx-InactivityTimer提前停止。
其中，drx-InactivityTimer是在指示新的数据传输的PDCCH之后第一个符号启动或重启，如图2所示，图中PDCCH调度新的PDSCH传输。
具体的，当UE处于DRX Active Time，UE会持续监听PDCCH，而当UE处于DRX非激活时间(non-Active Time，或者说处于DRX激活时间之外(outside DRX Active Time))，UE不监听PDCCH。这里的PDCCH的循环冗余校验(cyclic redundancy check，CRC)可以是如下的一种无线网络临时标识(radio network temporary identifier,RNTI)加扰的：小区无线网络临时标识(cell RNTI,C-RNTI),配置的调度无线网络临时标识(Configured Scheduling RNTI，CS-RNTI),中断无线网络临时标识(Interruption RNTI，INT-RNTI),时隙格式指示无线网络临时标识(Slot Format Indication RNTI，SFI-RNTI),半持续信道状态信息无线网络临时标识(Semi-Persistent CSI RNTI，SP-CSI-RNTI),PUCCH传输功率控制无线网络临时标识(transmit power control-PUCCH-RNTI，TPC-PUCCH-RNTI)，物理上行共享信道(physical uplink shared channel，PUSCH)传输功率控制无线网络临时标识(transmit power control-PUSCH-RNTI，TPC-PUSCH-RNTI),和探测参考信号(sounding reference signal，SRS)，传输功率控制无线网络临时标识(transmit power control-SRS-RNTI，TPC-SRS-RNTI)。
功率节省信号(power saving signal)，又可称为唤醒信号(WUS)，或睡眠信号(go-to-sleep signal，GTS)(以下均称为WUS)。
目前一般认为，发送在激活时间外的WUS位于DRX On Duration之前，用于指示UE在接下来的一个或多个DRX cycle是否需要唤醒去监听PDCCH。WUS可以包括以下几种实现方式：
(1)UE检测WUS，如果检测到WUS，则UE开启drx-onDurationTimer进入DRX On Duration去监听PDCCH，如果未检测到WUS，则UE不开启drx-onDurationTimer，即UE不需要在该DRX cycle唤醒，而进入睡眠状态节省功耗，如图3所示。
(2)UE检测WUS，如果检测到WUS，则UE不开启drx-onDurationTimer，即UE不需要在该DRX cycle唤醒，而进入睡眠状态节省功耗，如果未检测到WUS，UE开启drx-onDurationTimer进入DRX On Duration去监听PDCCH。
(3)UE检测WUS，通过WUS指示是否唤醒UE，例如通过下行控制信息(downlink  control information，DCI)中的1bit指示是否唤醒UE。
具体的，该WUS通过一种新的DCI格式发送，即DCI格式3_0(DCI format 3_0)，该DCI的CRC由功率节省网络临时标识(Power saving RNTI,PS-RNTI)加扰。因此，UE检测到WUS，又可描述为UE在WUS的监听时机检测到了DCI format 3_0。UE未检测到WUS，又可描述为UE在WUS的监听时机未检测到DCI format 3_0。
在新无线电(new radio，NR)中，UE可以通过接收和测量下行的信道状态信息参考信号(channel state information reference signal,CSI-RS)，从而得知下行信道状态信息(DL CSI)，UE将获取的CSI上报给基站，基站就获取了下行链路的CSI。而针对上行链路，同样的，网络可以配置或指示一些上行资源，UE在这些上行资源上发送探测参考信号(sounding reference signal,SRS)，基站通过测量UE发送的SRS从而可以获取上行链路的CSI。
其中，SRS发送时域行为包括3种：周期的(periodic)，半持续的(semi-persistent)，或非周期的(aperiodic)。
在时域上，SRS资源可以配置成周期的，或半持续的，或非周期的。SRS资源是通过RRC信令配置的。针对周期性SRS资源，在RRC信令生效之后，UE即开始在相应资源发送周期性SRS。针对半持续SRS资源，RRC信令配置之后，半持续SRS资源是非激活状态，UE不发送SRS，UE需要在收到用于激活半持续SRS资源的MAC CE信令之后，才在半持续SRS资源发送SRS，同样的，在收到用于去激活半持续SRS资源的MAC CE信令之后，UE停止发送SRS。针对非周期SRS资源，RRC信令配置之后，非周期SRS资源也是非激活状态，UE需要在收到用于激活非周期SRS资源的DCI之后，在DCI触发的非周期SRS资源上发送非周期SRS。
RRC信令(RRC IE SRS-Config)可以配置一系列SRS资源集合(SRS-ResourceSet)和一系列SRS资源(SRS-Resource)。一个SRS资源集合包括1个或多个SRS资源。
网络针对一个SRS资源集合可以配置一个或多个功能。例如，SRS的功能可以包括以下4种：
用于波束管理。基于波束管理的SRS，基站端可以选择合适的接收/发送波束，基站也可以指示UE选择合适的发送或接收波束；波束管理也可以理解成是准共址(Quasi Co-Location,QCL)管理。例如若SRS资源用于波束管理，网络设备指示用于发送PUSCH的参考信号为某一个SRS资源，其实是指示了所述PUSCH和所述某一个SRS资源之间具有QCL关系，这样，UE可以以和发送所述某一个SRS资源相同的预编码来发送所述PUSCH资源。另外，两个波束方向相同，可以认为两个波束采用了相同的QCL参数。
用于基于码本(codebook)的上行(multiuser MIMO,MU-MIMO)传输；例如，基于该功能的SRS，基站可以指示UE选择合适的码本(预编码，precoder)执行PUSCH的发送；
用于基于非码本(non-codebook)的上行传输；例如，基于该功能的SRS，基站可以指示UE参照哪一个参考信号资源(例如SRS资源)执行PUSCH的发送；
用于天线端口(antenna port)切换(antenna switching)；例如，基于该功能的SRS，基站可以获取下行链路的CSI。
当配置了WUS时，如果基站连续多个WUS都指示不唤醒UE，则UE在连续多个DRX 周期都不启动drx-onDurationTimer，从而未进入DRX active time，因此，UE会长时间未被唤醒，可能造成上行链路中断。具体的，UE长时间不发送SRS，基站无法获取UE的定时提前(timing advance,TA)，可能会造成UE丢失上行同步，进而导致UE上行链路中断。
此外，UE长时间不发送SRS，还可能造成基站无法获取UE的准确的上行信道状态信息(channel state information，CSI)。由于根据UE的上行CSI，基站可以执行多用户MIMO配对，而上行CSI不准确，势必降低MU-MIMO的性能。尤其针对时分双工(time-division duplex，TDD)网络，基站通过上行CSI，根据信道互异性，推导出下行CSI。所以UE长时间不发送SRS，也会影响下行链路的性能。
本申请主要应用于第5代无线通信系统(new radio，NR)系统，还可以应用于其它的通信系统，例如，窄带物联网(narrow band-internet of things，NB-IoT)系统，机器类通信(machine type communication，MTC)系统，未来下一代通信系统等。
本申请实施例中涉及的网元包括终端设备和网络设备。如图4所示，网络设备和终端设备组成一个通信系统，在该通信系统中，网络设备通过下行信道发送信息给终端设备，终端设备通过上行信道发送信息给网络设备。其中，终端设备可以为手机、平板电脑、带无线收发功能的电脑、物联网终端设备等，也可以称为移动站(mobile station)、移动台(mobile)、远程站(remote station)、远程终端(remote terminal)、接入终端(access terminal)、用户代理(user agent)，还可以为车与车(vehicle-to-vehicle，V2V)通信中的汽车、机器类通信中的机器等，在此不作限定。网络设备可以为各种形式的基站，例如：宏基站，微基站(也称为小站)，中继站，接入点、演进型基站(eNodeB)、无线保真接入点(wireless fidelity access point，WiFi AP)、全球微波接入互操作性(worldwide interoperability for microwave access base station，WiMAX BS)等，在此不作限定。此外，在采用不同的无线接入技术的系统中，具备提供无线接入功能的网络设备的名称可能会有所不同，例如，在LTE系统中，称为演进的节点B(evolved NodeB，eNB或者eNodeB)，在第三代(3rd generation，3G)系统中，称为节点B(Node B)，在NR系统中，称为gNB。
上述各网元既可以是在专用硬件上实现的网络元件，也可以是在专用硬件上运行的软件实例，或者是在适当平台上虚拟化功能的实例。此外，本申请实施例还可以适用于面向未来的其他通信技术。本申请描述的网络架构以及业务场景是为了更加清楚的说明本申请的技术方案，并不构成对本申请提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请提供的技术方案对于类似的技术问题，同样适用。
实施例1：本申请提供一种参考信号发送和接收方法，用以解决UE长时间未被唤醒，可能造成上行链路中断的问题。如图5所示，该方法包括：
S501：网络设备发送第一信息，第一信息用于配置终端设备能够发送参考信号的资源。相应的，终端设备接收来自于网络设备的第一信息。
S502：终端设备确定该资源处于DRX非激活时间，基于该资源发送参考信号。
此外，若终端设备确定该资源处于DRX激活时间，有如下几种可能的设计：
在一种可能的设计中，若终端设备确定该资源处于DRX激活时间，终端设备基于该资源发送参考信号。这样，不管终端设备是否处于DRX激活时间，终端设备都基于该资 源发送参考信号，可以解决UE长时间未被唤醒可能造成上行链路中断的问题。
在另一种可能的设计中，若终端设备确定该资源处于DRX激活时间，终端设备不基于该资源发送参考信号。可以理解的是，网络设备在所述资源之外，配置了用于在DRX激活时间内发送的其他资源，在DRX激活时间内，终端设备可以基于所述其他资源发送参考信号。而在DRX激活时间以外，终端设备在所述其他资源上不发送参考信号，而是基于所述资源发送参考信号。这样，当UE长时间处于DRX非激活时间时，仍然可以基于所述资源发送参考信号，可以解决UE长时间未被唤醒可能造成上行链路中断的问题。
其中，该资源可以为时间窗或第一参考信号资源。若该资源为时间窗，终端设备确定该时间窗处于DRX非激活时间，终端设备在该时间窗内发送参考信号；若该资源为第一参考信号资源，终端设备确定第一参考信号资源对应的时域位置处于DRX非激活时间，终端设备在第一参考信号资源上发送参考信号。
应理解的是，本申请中所述参考信号可以为SRS，且不限定SRS的具体功能。
应理解的是，终端设备在时间窗内发送参考信号，是在时间窗内的参考信号资源上发送参考信号。
所述时间窗内的参考信号资源，有如下几种可能的设计：
在一种可能的设计中，所述时间窗内的参考信号资源是网络设备已经配置好的参考信号资源，例如如上所述的网络设备配置的用于在DRX激活时间内发送的其他资源。此时，若所述其他资源位于DRX激活时间，则UE在所述其他资源发送参考信号；若所述其他资源不位于DRX激活时间，但位于所述时间窗内，则UE也在所述其他资源发送参考信号；若所述其他资源既不位于DRX激活时间，也不位于所述时间窗内，则UE不在所述其他资源发送参考信号。
在另一种可能的设计中，所述时间窗内的参考信号资源是网络设备针对所述时间窗专门配置的参考信号资源。
可选的，所述专门配置的参考信号资源只位于所述时间窗内。
可选的，所述专门配置的参考信号资源中，有一部分位于所述时间窗内，其他部分位于所述时间窗外。
针对位于所述时间窗外的专门配置的参考信号资源，若这些资源位于DRX激活时间外，UE不在这些资源上发送参考信号；
若这些资源位于DRX激活时间内，一种实现方式是UE在这些资源上发送参考信号，另一种实现方式是UE不在这些资源上发送参考信号。采用哪种实现方式可以是协议规定，也可以是由网络设备配置。
在另一种可能的设计中，所述时间窗内的参考信号资源既包括已经配置好的参考信号资源，也包括网络设备针对所述时间窗专门配置的参考信号资源。
针对时间窗，可以包括但不限于以下几种可能的设计：
在一种可能的设计中，时间窗为DRX持续时间，或DRX持续时间内的一个时间段，或DRX持续时间之前的一个时间段。
例如，时间窗为DRX持续时间内前K个时隙，或最后K个时隙。
当采用正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)调制技术时，一个时隙包括14个OFDM符号或12个OFDM符号。
所述子帧绝对时间长度为1毫秒。根据不同的子载波间隔(subcarrier spacing,SCS)， 一个子帧可以包括不同的时隙个数。例如，针对15KHz的SCS，一个子帧包括1个时隙，针对30KHz的子载波间隔，1个子帧包括2个时隙。针对n*15KHz的子载波间隔，一个子帧包括n个时隙。例如，n为偶数。
所述微时隙的时长小于1个时隙的时长，例如，1个微时隙为M个OFDM符号。M小于14或小于12。
又例如，时间窗为WUS监听时机和相应的DRX持续时间之间的时间段。
又例如，时间窗为WUS监听时机之前的一个时间段。这样，UE可以在检测WUS之前发送参考信号，可以提高WUS的性能。例如，所述参考信号可以用于波束管理，基站可以基于所述参考信号选择一个合适的发送波束发送WUS。可选的，所述时间窗与WUS监听时机之间的时间间隔大于或等于一定时长，所述一定时长大于或等于基站/UE用于波束管理/选择的时间。
在一种可能的设计中，时间窗在WUS监听时机之后，且与WUS监听时机之间的时间间隔大于或等于时长A，所述时长A大于或等于UE解析WUS DCI的时间。这样，在某些实现方式中，UE可以在判断WUS是否指示UE唤醒之后，根据WUS的指示或高层信令配置或协议规定，从而决定在所述时间窗是否发送参考信号。
在一种可能的设计中，时间窗在WUS监听时机之后，且与WUS监听时机之间的时间间隔小于或等于时长B。这样，在某些实现方式中，如果WUS指示UE不需要唤醒，UE可以尽快在时间窗内发送参考信号，之后回到睡眠状态，这样可以使UE维持较短的唤醒时间，从而节省UE功耗。
在另一种可能的设计中，时间窗为同步信号块(synchronization signal/PBCH Block,SSB)之前的时间段，或SSB之后的时间段，或包含SSB的时间段。
在另一种可能的设计中，时间窗为同步信号块测量时间配置窗(SSB measurement timing configuration,SMTC)之前的时间段，或SMTC之后的时间段，或包含SMTC的时间段。
由于UE会被配置一些测量，比如无线电资源管理(radio resource management，RRM)测量，UE在DRX非激活时间也可以基于SSB执行RRM测量。所以若所述时间窗位于SSB附近或SMTC附近，UE在DRX非激活时间时，UE在所述时间窗内发送参考信号，如果UE也基于SSB执行RRM测量，则UE可以维持较短的唤醒时间，可以节省UE功耗。这样配置，也可以减少UE的唤醒次数，可以节省UE功耗。
在一种可能的设计中，第一信息可以配置时间窗的周期，即所述时间窗周期性的出现。时间窗的周期为DRX周期的M倍，或SSB周期的M倍，或SMTC周期的M倍，或唤醒信号周期的M倍，其中，M为正整数。M值可以由网络设备配置，或者协议规定。
其中，DRX周期可以为长DRX周期(long DRX cycle)，或短DRX周期(short DRX cycle)。所述一个长DRX周期(long DRX cycle)和一个短DRX周期(short DRX cycle)的时长均是由网络设备配置的。
由于在DRX持续时间之前可能存在1个或多个WUS监听时机，WUS周期等于相邻的两个时间段的起始时刻(或结束时刻)之间的时间间隔。所述时间段包括一个DRX持续时间之前的(以及上一个DRX持续时间之后的)一个或多个WUS监听时机。可选的，WUS周期等于C-DRX周期，即每个on duration之前都有WUS监听时机。或者，WUS周期也可以大于C-DRX周期，比如可以是C-DRX周期的整数倍。例如，每隔一个DRX持 续时间，DRX持续时间前面才有WUS监听时机，即WUS监听时机为C-DRX周期的2倍，该WUS同时指示后面的两个DRX周期是否都唤醒或都不唤醒。
示例性地，如图6所示，时间窗的周期为DRX周期的3倍，时间窗为DRX持续时间。
在一种可能的设计中，终端设备接收来自于网络设备的第三信息，第三信息用于配置针对时间窗配置的第二参考信号资源。其中，第二参考信号资源为针对时间窗配置的专用资源。示例性地，若第二参考信号资源和时间窗均基于周期性配置，则该第二参考信号资源可以与时间窗具有相同的周期。另一示例中，如上所述，该第二参考信号资源可以与时间窗具有不同的周期，比如第二参考信号资源的周期小于时间窗的周期，这样，针对位于时间窗外的第二参考信号资源，UE是否发送参考信号按照如上描述。
此外，终端设备在时间窗内的采用的参考信号资源还可以为非针对时间窗配置的资源。
应理解的是，上述无论是针对时间窗配置的专用资源还是非针对时间窗配置的资源可以为周期性的，和/或半持续SRS资源。若配置成半持续的，只有在参考信号资源被激活之后，UE才基于该资源发送参考信号；在参考信号资源被去激活之后，UE不基于该资源发送参考信号。激活信令可以是MAC CE信令，也可以是物理层信令，比如DCI。
应理解的是，对于针对时间窗配置的第二参考信号资源，网络设备可以配置一个或多个这样的参考信号资源，或者配置一个或多个参考信号资源集合，包括所述一个或多个第二参考信号资源。
应理解的是，对于第一参考信号资源，网络设备可以配置一个或多个这样的参考信号资源，或者配置一个或多个参考信号资源集合，包括所述一个或多个第一参考信号资源。
针对时间窗的配置方式，还有如下多种设计。
示例性地，第一信息可以配置时间窗的长度，周期，和时间偏移等参数。
其中，时间窗的长度的单位可以为：时隙，微时隙，符号，子帧，毫秒(ms)等。时间窗的周期的单位可以为：时隙，微时隙，子帧，毫秒(ms)，秒(s)等。时间窗的时间偏移的单位和周期的单位相同。
在一种可能的设计中，第一信息包括1个周期参数和1个时间偏移参数。或第一信息包括1个周期参数和多个时间偏移参数。当有多个时间偏移参数时，不同时间偏移参数的单位不同。例如，一个时间偏移的单位为子帧，表示子帧偏移，一个时间偏移的单位为时隙，表示时隙偏移，一个时间偏移的单位为符号，表示符号偏移。
进一步地，通过上述参数，然后根据一定的预定义规则，或者按照一定的计算公式，可以计算出每个时间窗的起始时刻所在的时域位置，例如，时间窗的起始时刻所在的系统帧号(SFN,system frame number)，以及时间窗的起始时刻在一个帧中的具体子帧，或时隙，或符号。
应理解的是，以下各个方案仅为举例，不作为本申请实施例的限定。
方案1：
第一信息包括时间窗的周期，和2个时间偏移。其中，1个时间偏移为周期偏移，另1个时间偏移为时隙偏移。周期偏移与周期的单位相同。例如，周期和周期偏移的单位均为毫秒(ms)。
周期以T表示，周期偏移以T_offset表示，时隙偏移以T_slotOffset表示。
时间窗的起始时刻所在的SFN和子帧subframe由如下公式确定：
[(SFN×10)+subframe number]modulo T＝T_offset；
进一步，再根据时间窗的时隙偏移就可以确定时间窗的起始时刻在确定的子帧中的具体时隙。
可选的，第一信息还包括第3个时间偏移，单位为符号，为符号偏移，记为T_symbolOffset，通过符号偏移可以进一步确定时间窗的起始时刻在确定的时隙中所在的具体符号。
方案2：
第一信息包括时间窗的周期，和1个时间偏移。所述周期和时间偏移的单位均为时隙(slot)。记周期为T1，时间偏移为T1_slotOffset。
时间窗的起始时刻所在的SFN和所确定的帧中的时隙编号
Figure PCTCN2019116887-appb-000001
由如下公式确定：
Figure PCTCN2019116887-appb-000002
其中，
Figure PCTCN2019116887-appb-000003
表示子载波间隔(subcarrier spacing,SCS)为μ的一个帧中的时隙个数，
Figure PCTCN2019116887-appb-000004
表示SCS为μ的一个帧中的时隙编号。
可选的，第一信息还包括第2个时间偏移，单位为符号，为符号偏移，记为T1_symbolOffset，通过符号偏移可以进一步确定时间窗的起始时刻在确定的时隙中所在的具体符号。
方案3：
第一信息包括时间窗的长度和相对时间偏移等参数。
相对时间偏移为时间窗的起始时刻和第一时域位置之间的时间间隔，或时间窗的结束时刻和第一时域位置之间的时间间隔。其中，第一时域位置可以是DRX持续时间的起始时刻、或DRX持续时间之前的WUS监听时机、或DRX持续时间之前的包含WUS监听时机的一个时间段的起始时刻或结束时刻。应理解的是，当WUS监听时机只占据一个OFDM符号时，所述第一时域位置是WUS所在符号，或WUS所在符号的起始时刻或结束时刻。当WUS监听时机占据多个OFDM符号或占据多个时隙时，所述第一时域位置是WUS监听时机的起始符号，或WUS监听时机的起始符号所在时隙的起始符号，或WUS监听时机的结束符号，或WUS监听时机的结束符号所在时隙的结束符号。
例如，如图7所示，第一信息包括时间窗的长度和相对时间偏移，该相对时间偏移为时间窗的结束时刻与DRX持续时间的起始时刻之间的时间间隔。
方案4：第一信息包括1个或2个时间偏移参数。
作为一种可能的实现方式，第一信息包括1个时间偏移参数，通过所述1个时间偏移参数和预设时域位置确定所述窗。通过所述1个时间偏移参数确定出时间窗的起始时刻(或结束时刻)，则时间窗的结束时刻(或起始时刻)为预设时域位置。预设时域位置的实现方式和如上第一时域位置的实现方式相同，不再赘述。
可选的，所述1个时间偏移还可以为相对于预设时域位置的偏移。例如，所述预设时域位置为DRX持续时间的起始时刻，即时间窗的结束时刻为DRX持续时间的起始时刻。所述1个时间偏移为相对于WUS监听时机的偏移，通过该偏移可以确定时间窗的起始时刻。又例如，所述预设时域位置为WUS监听时机的结束时刻。所述1个时间偏移为相对于DRX持续时间的起始时刻的偏移。又例如，所述预设时域位置为WUS监听时机的起始时刻。所述1个时间偏移为相对于DRX持续时间的起始时刻的偏移。
作为一种可能的实现方式，第一信息包括2个时间偏移参数，，通过所述2个时间偏移参数确定时间窗。示例性地，所述2个时间偏移参数为相对同一个预设时域位置的偏移。 或所述2个时间偏移参数为相对不同预设时域位置的偏移。
方案5：
时间窗为部分DRX持续时间，例如时间窗为每N个DRX持续时间中的第一个。将这些部分DRX持续时间称为特定持续时间(特定on duration)，下面举例特定on duration的具体配置方式。
示例1、网络设备配置特定on duration的周期。
具体的，根据特定on duration的周期，和已经配置好的DRX周期偏移(drx-StartOffset)和时隙偏移(drx-Slotoffset)等参数，可以确定特定on duration的时域位置。
所述DRX周期偏移(drx-StartOffset)和时隙偏移(drx-Slotoffset)等参数位于DRX-Config IE。所述DRX周期偏移(drx-StartOffset)由DRX-Config IE中的参数drx-LongCycleStartOffset确定。
作为一种可选的实施方式，网络设备配置特定on duration的周期为DRX长周期的N倍，N大于或等于1。
实施例2：本申请提供一种参考信号发送和接收方法，用以解决UE长时间未被唤醒，可能造成上行链路中断的问题。如图8所示，该方法包括：
S801：网络设备发送第一信息，第一信息用于配置终端设备能够发送参考信号的资源。相应的，终端设备接收来自于网络设备的第一信息。
网络设备配置的资源可以参考上述实施例中的内容，重复之处不再赘述。
S802：终端设备检测来自于网络设备的唤醒信号。
S803a：若未检测到唤醒信号且终端设备确定不唤醒终端设备，或者检测到唤醒信号且唤醒信号指示不唤醒终端设备，终端设备基于该资源发送参考信号。
S803b：若未检测到唤醒信号且终端设备确定唤醒终端设备，或者检测到唤醒信号且唤醒信号指示唤醒终端设备，终端设备基于该资源发送参考信号。
采用上述方法，第一信息配置的终端设备能够发送参考信号的资源不受唤醒信号的约束，无论是否唤醒终端设备，终端设备基于该资源发送参考信号。
应理解的是，网络设备还可以配置其他资源。当UE处于DRX激活时间内，UE在其他资源发送参考信号，当UE处于DRX非激活时间内，UE在其他资源不发送参考信号。
实施例3：本申请提供一种参考信号发送和接收方法，用以解决UE长时间未被唤醒，可能造成上行链路中断的问题。如图9所示，该方法包括：
S901：网络设备发送第一信息，第一信息用于配置终端设备能够发送参考信号的资源。相应的，终端设备接收来自于网络设备的第一信息。
网络设备配置的资源可以参考上述实施例中的内容，重复之处不再赘述。
S902：网络设备发送第二信息，第二信息用于指示第一时长，第一时长为终端设备连续未被唤醒的时长。
应理解的是，第一信息和第二信息可以分开发送或者一起发送。例如，第一信息和第二信息为同一信息中的两个不同的信息域。
S903：终端设备确定终端设备未被唤醒的时长到达第一时长，终端设备基于该资源发送参考信号。
应理解的是，若终端设备确定终端设备未被唤醒的时长未到达第一时长，即使遇到所述资源，也不发送参考信号。
示例性地，若所述资源为时间窗，该时间窗可以周期性配置，UE未被唤醒的时长未到达第一时长时，即使遇到所述时间窗，且所述时间窗位于DRX非激活时间，UE也不在所述时间窗内发送参考信号。同理，若所述资源为第一参考信号资源，第一参考信号资源可以周期性配置，UE未被唤醒的时长未到达第一时长时，即使遇到所述第一参考信号资源，且所述第一参考信号资源位于DRX非激活时间，UE也不在所述第一参考信号资源发送参考信号。
应理解的是，当UE被唤醒时，第一时长累积计时/计数要置成初始值，重新累积计时/计数。另外，当WUS指示UE不唤醒，但由于UE判断未被唤醒的时长到达第一时长而唤醒，在所述资源上发送参考信号，第一时长累积计时/计数也要置成初始值，重新累积计时/计数。
在一种可能的设计中，第一时长为N个DRX周期，该资源为N个DRX周期之后的第1个DRX持续时间，或该资源为N个DRX周期之后的第1个DRX持续时间内的一个时间段，或该资源为N个DRX周期之后的第1个DRX持续时间之前的一个时间段，或该资源为所述N个DRX周期之后的第1个DRX持续时间之后的、且在所述N个DRX周期之后的第2个DRX持续时间之前的一个时间段，或该资源为N个DRX周期之后的第1个DRX持续时间内的M个参考信号资源，或该资源为所述N个DRX周期之后的第1个DRX持续时间之后的、且在所述N个DRX周期之后的第2个DRX持续时间之前的M个参考信号资源，或该资源为N个DRX周期之后的第1个DRX持续时间之前的M个参考信号资源，N和M为正整数。N和M值可以由网络设备配置，或由协议规定。
可选的，所述M个参考信号资源是针对同一个参考信号资源的M个参考信号资源周期所包括的参考信号资源。例如，所述M个参考信号资源是第一参考信号资源的M个参考信号资源周期所包括的参考信号资源。又例如，所述M个参考信号资源是如上所述的网络设备配置的其他资源的M个参考信号资源周期所包括的参考信号资源。
其中，DRX周期可以是长DRX周期或短DRX周期。
针对第一时长，还有如下几种设计：
在一种可能的设计中，第一时长为连续P个WUS都指示不唤醒时UE睡眠的时长，或者连续P个WUS未检测到且终端设备确定不唤醒的时长，或者UE连续检测P个WUS(不管是否检测到WUS)，UE都确定不唤醒时睡眠的时长。终端设备确定终端设备未被唤醒的时长到达第一时长，可以是，终端设备确定连续P个WUS都指示UE不唤醒。P值可以由网络配置，或协议规定。
应理解的是，若一个DRX持续时间之前有多个WUS监听时机，则1个WUS对应所述多个WUS监听时机。所以，所述P个WUS对应P个DRX持续时间。
此时，终端设备确定终端设备未被唤醒的时长到达第一时长又可描述为，终端设备确定终端设备连续未被唤醒的次数到达第一次数，这里的第一次数为连续检测到的WUS指示不唤醒终端设备的次数，或连续未检测到的WUS且终端设备确定不唤醒的次数。
在另一种可能的设计中，网络设备配置第一时长的时间长度。例如第一时长的单位可以是秒，毫秒(ms),帧，子帧，时隙等。
在另一种可能的设计中，所述资源不是周期性配置的，而是通过条件触发一个非周期资源，例如，所述条件为终端设备确定终端设备未被唤醒的时长到达第一时长。所述非周期资源可以是非周期时间窗，也可以是非周期参考信号资源。
采用上述方法，终端设备确定长时间未发送参考信号后，能够及时发送参考信号，保证上行链路不中断。
实施例4：本申请提供一种参考信号发送和接收方法，用以解决UE长时间未被唤醒，可能造成上行链路中断的问题。如图10所示，该方法包括：
S1001：网络设备发送第一信息，第一信息用于配置终端设备能够发送参考信号的资源。第一信息配置的资源为时间窗或第一参考信号资源。相应的，终端设备接收来自于网络设备的第一信息。
网络设备配置的所述资源可以参考上述实施例中的内容，重复之处不再赘述。
S1002：终端设备检测来自于网络设备的唤醒信号。
S1003a：若未检测到唤醒信号且终端设备确定不唤醒终端设备，或者检测到唤醒信号且唤醒信号指示不唤醒终端设备，终端设备基于所述资源发送参考信号。
S1003b：若未检测到唤醒信号且终端设备确定唤醒终端设备，或者检测到唤醒信号且唤醒信号指示唤醒终端设备，终端设备不基于所述资源发送参考信号。
应理解的是，终端设备唤醒后在DRX active time内正常发送参考信号。
采用上述方法，终端设备在非激活时间基于该资源发送参考信号后，在激活时间停止基于该资源发送参考信号。
应理解的是，若未检测到唤醒信号且终端设备确定唤醒终端设备，或者检测到唤醒信号且唤醒信号指示唤醒终端设备，终端设备不基于所述资源发送参考信号。此时所述资源是否位于DRX激活时间，有如下几种实现方式：
方式1：此时所述资源位于DRX非激活时间。
例如，所述资源位于WUS监听时机和DRX持续时间之前，由于UE即将要在DRX持续时间唤醒进入DRX激活时间，UE可以在激活时间内正常发送参考信号，所以UE不必基于所述资源发送参考信号。
又例如，所述资源位于UE唤醒的DRX持续时间之后，以及下一个DRX持续时间之前，且在所述资源之前，UE又进入DRX非激活时间，比如网络设备发送MAC CE信令终止了UE的DRX非激活定时器(drx-InactivityTimer)，此时，由于UE已经在UE唤醒的DRX激活时间内(例如UE唤醒的DRX持续时间内)正常发送了参考信号，所以UE不必基于所述资源发送参考信号，可以减少UE发送参考信号的次数，节省UE功耗。
方式2：此时所述资源位于DRX激活时间。
此时，若所述资源和DRX激活时间内的如上所述的其他资源时域和频域完全重叠，则UE在所述资源发送参考信号，若所述资源和DRX激活时间内的如上所述的其他资源时域和频域不完全重叠，则UE在所述资源不发送参考信号。
应理解的是，当判断是否资源重叠时，若所述资源为时间窗，是所述时间窗内的参考信号资源和所述其他资源之间判断是否资源重叠。
实施例5：本申请提供一种参考信号发送和接收方法，用以解决UE长时间未被唤醒，可能造成上行链路中断的问题。如图11所示，该方法包括：
S1101：网络设备发送第一信息，第一信息用于配置终端设备能够发送参考信号的资源。在本实施例中，若第一信息配置的资源为时间窗，该时间窗位于唤醒信号和DRX持续时间之间。若第一信息配置的资源为第一参考信号资源，所述第一参考信号资源的时域位置位于唤醒信号和DRX持续时间之间。相应的，终端设备接收来自于网络设备的第一 信息。
网络设备配置的所述资源可以参考上述实施例中的内容，重复之处不再赘述。
S1102：终端设备检测来自于网络设备的唤醒信号。
S1103a：若未检测到唤醒信号且终端设备确定不唤醒终端设备，或者检测到唤醒信号且唤醒信号指示不唤醒终端设备，终端设备基于所述资源不发送参考信号。
S1103b：若未检测到唤醒信号且终端设备确定唤醒终端设备，或者检测到唤醒信号且唤醒信号指示唤醒终端设备，终端设备基于所述资源发送参考信号。
采用上述方法，当所述资源位于唤醒信号和DRX持续时间之间，终端设备确定唤醒终端设备，则终端设备可以尽快在要唤醒的DRX持续时间之前发送参考信号，进而可以实现快速恢复上行链路。由于是在DRX持续时间之前发送参考信号，且恢复上行链路，所以并不会影响UE在DRX持续时间定时器启动之后的数据收发的性能。而若未检测到唤醒信号且终端设备确定不唤醒终端设备，或者检测到唤醒信号且唤醒信号指示不唤醒终端设备，UE不发送参考信号，这样可以极大的节省UE功耗。
所述资源可以是周期性配置的。
或，所述资源是非周期性配置的，只有在未检测到唤醒信号且终端设备确定唤醒终端设备，或者检测到唤醒信号且唤醒信号指示唤醒终端设备时，才触发所述非周期配置的所述资源。
除了上述实施例中的资源配置方式，若所述资源为第一参考信号资源，所述第一参考信号资源可以是如上所述的其他资源的子集。例如，所述第一参考信号资源和如上所述的其他资源中的部分周期内的参考信号资源的时域和频域完全相同。
除了如上所述的配置方式，也可以通过协议规定的方式规定所述资源。例如，协议规定，若未检测到唤醒信号且终端设备确定唤醒终端设备，或者检测到唤醒信号且唤醒信号指示唤醒终端设备，则UE在WUS和相应的DRX持续时间之间的所述其他资源的M个资源上发送所述参考信号。所述M个表示的是其他资源的M个周期内的参考信号资源。所述其他资源可以是一个或多个其他参考信号资源，网络设备可以配置或协议规定所述其他资源是哪些其他资源。
例如，协议可以规定所述M个资源是DRX持续时间之前的与DRX持续时间最接近的第一个其他资源，或WUS监听时机之后的第一个其他资源，或与DRX持续时间起始时刻相距时间间隔大于等于时长C的第一个其他资源，或WUS监听时机之后，且与WUS监听时机相距时间间隔大于等于时长D的第一个其他资源。
若所述资源为时间窗，协议可以规定所述时间窗为WUS监听时机和DRX持续时间之间的时间段。
实施例6：本申请提供一种参考信号发送和接收方法，用以解决UE长时间未被唤醒，可能造成上行链路中断的问题。如图12所示，该方法包括：
S1201：网络设备发送第一信息，第一信息用于配置终端设备能够发送参考信号的资源。第一信息配置的资源为第一参考信号资源。相应的，终端设备接收来自于网络设备的第一信息。
S1202：网络设备发送第四信息，第四信息用于配置第二参考信号资源。
应理解的是，第一信息和第四信息可以分开发送或在一起发送。例如，分开在不同消息发送或在同一消息中发送。分开在不同消息发送可以是不同时间发送，也可以是相同时 间发送。
在一种可能的设计中，第一参考信号资源对应的频域资源和第二参考信号资源对应的频域资源相同，第一参考信号资源的周期和第二参考信号资源的周期不同。
在一示例中，两套参考信号资源的周期分别为周期1和周期2，两套参考信号资源可以对应同一套SRS资源。
例如，周期2对应的资源可以是周期1对应资源的子集。例如，网络设备配置2个周期参数：周期1和周期2。其中周期2是周期1的M倍。M为大于或等于1的整数。网络设备可以配置M值，网络设备也可以直接配置周期1和周期2的大小。
针对确定参考信号资源的时域位置的周期偏移参数，网络设备可以配置2个或1个周期偏移参数。当配置2个周期偏移参数时，周期1和周期2分别对应这2个周期偏移参数。当配置1个周期偏移参数时，周期1和周期2共用这1个周期偏移参数。通过周期和周期偏移可以计算出参考信号资源的时域位置。
如上所述的指示周期1、周期2、周期偏移的参数位于同一个参考信号资源配置信元(information element,IE)中。
在另一示例中，对于一个SRS资源(例如，该资源即为第二参考信号资源)，每隔M个SRS周期(或者说每隔M个SRS资源)，选取N个SRS资源(或选取N个时间长度的SRS资源)(这些N个SRS资源(或N个时间长度的SRS资源)即为第一参考信号资源)。
其中，M和N的取值可以是协议预先规定好的，或者M和N值支持高层信令可配置。当高层信令可配置M和N的取值时，如果网络设备未配置M和N的取值(例如第一信息配置两套参考信号资源，第一信息中缺省了指示M和N的取值的相应参数)，协议可以预先规定好一个默认的M和N值。
在另一示例中，周期1对应一套SRS资源，周期2对应另一套SRS资源。网络设备通过两个SRS-Resource IE分别配置周期1对应的SRS资源和周期2对应的SRS资源。
S1203：终端设备检测来自于网络设备的唤醒信号。
S1204a：若未检测到唤醒信号且终端设备确定不唤醒终端设备，或者检测到唤醒信号且唤醒信号指示不唤醒终端设备，终端设备在第一参考信号资源上发送参考信号，且终端设备在第二参考信号资源上不发送参考信号。
S1204b：若未检测到唤醒信号且终端设备确定唤醒终端设备，或者检测到唤醒信号且唤醒信号指示唤醒终端设备，终端设备在第二参考信号资源上发送参考信号。
针对第一参考信号资源，若未检测到唤醒信号且终端设备确定唤醒终端设备，或者检测到唤醒信号且唤醒信号指示唤醒终端设备，有如下2种实现方式：
方式1：终端设备在第一参考信号资源上发送参考信号。
采用上述方法，终端设备可以在唤醒和不唤醒时都在第一参考信号资源发送参考信号。
方式2：终端设备在第一参考信号资源上不发送参考信号。
应理解的是，针对方式2，如果两套资源有部分资源重叠，则重叠的SRS资源不受WUS影响，即不管唤醒还是不唤醒终端设备，UE在重叠的SRS资源上发送SRS。
采用上述方法，终端设备可以在唤醒和不唤醒时分别采用不同的参考信号资源发送参考信号。
应理解的是，针对第一参考信号资源和第二参考信号资源，网络设备分别可以配置一个或多个。
实施例7：本申请提供一种参考信号发送和接收方法，用以解决UE长时间未被唤醒，可能造成上行链路中断的问题。如图13所示，该方法可用于载波聚合(carrier aggregation,CA)场景，包括：
S1301：网络设备向终端设备发送唤醒信号，唤醒信号指示不唤醒终端设备，唤醒信号包括的第一信息域用于指示终端设备在主小区和/或辅小区是否发送参考信号。
S1302a：若第一信息域指示终端设备在主小区发送参考信号，终端设备在主小区发送参考信号。
S1302b：若第一信息域指示终端设备在辅小区发送参考信号，终端设备在辅小区发送参考信号。
S1302c：若第一信息域指示终端设备在主小区和辅小区发送参考信号，终端设备在主小区和辅小区发送参考信号。
所述第一信息域用于指示终端设备在主小区和/或辅小区是否发送参考信号，该指示的生效时间有如下几种设计：
在一种可能的设计中，所述生效时间为WUS指示UE不唤醒的DRX持续时间。
在另一种可能的设计中，所述生效时间为WUS指示UE不唤醒的DRX周期。
在一种可能的设计中，第一信息域用于当唤醒信号指示唤醒终端设备时，指示终端设备在辅小区是否从第一行为回到第二行为，和/或指示终端设备在辅小区是否从第二行为回到第一行为。第一行为是指终端设备在辅小区监听PDCCH，应理解的是，UE在辅小区监听PDCCH表示UE处于DRX激活时间；第二行为是指终端设备在辅小区停止监听PDCCH；并在辅小区执行背景处理，背景处理包括如下至少一种：信道状态信息CSI测量，或上报CSI，或在辅小区发送参考信号。
在一种可能的设计中，第一信息域还用于指示当唤醒信号指示不唤醒终端设备时，指示终端设备在主小区和/或辅小区是否执行第三行为，第三行为包括如下至少一种：CSI测量，或上报CSI，或半持续数据调度。
此外，第一信息域还可以用于指示当唤醒信号指示不唤醒终端设备时，下行参考信号是否存在。例如，所述下行参考信号可以是CSI-RS，或用于RRM测量的CSI-RS。
所述半持续数据调度包括如下至少一种：
下行半持续数据调度，例如由CS-RNTI加扰的下行控制信息触发的下行半持续数据调度；
上行半持续数据，例如由CS-RNTI加扰的下行控制信息触发的上行半持续数据调度，或RRC信令配置的上行半持续数据调度。
第一信息域包括至少一个比特。至少一个比特中的其中一个比特或其中一个比特状态用于指示终端设备是否在主小区发送参考信号，至少一个比特中的其他比特中的其中一个比特或其他比特状态中的其中一个比特状态用于指示终端设备是否在辅小区发送参考信号。以下结合具体举例说明书第一信息域指示的不同内容。应理解的是，以下举例不作为本申请实施例的限定。
示例1：第一信息域包括1比特，当WUS指示UE唤醒时，该1比特对应一个辅小区组，一个辅小区组包括一个或多个处于激活状态的辅小区。当WUS指示UE睡眠时，该比特置1(或0)指示终端设备在主小区发送参考信号，该比特置0(或1)指示终端设备不在主小区发送参考信号，默认配置终端设备在所述辅小区组内的所有辅小区或所有处于 激活状态的辅小区不发送参考信号。或者，该比特置1(或0)指示终端设备在主小区和所述辅小区组内的所有辅小区发送参考信号，该比特置0(或1)指示终端设备不在主小区和所述辅小区组内的所有辅小区发送参考信号，其他处于激活状态的辅小区可以配置或协议规定为发送或不发送参考信号。
或者，该比特置1(或0)指示终端设备在选定的至少一个辅小区或全部辅小区发送参考信号，该比特置0(或1)指示终端设备不在选中的至少一个辅小区或选中的至少一个辅小区组或全部辅小区发送参考信号，默认配置终端设备在主小区发送参考信号。这里的选定的辅小区可以由网络配置或协议规定。默认配置终端设备在未选中的辅小区或未选中的辅小区组不发送参考信号。
示例2：第一信息域包括2比特，共可以指示4种比特状态，第一信息域的指示方案可以如表1所示。
Figure PCTCN2019116887-appb-000005
表1
应理解的是，上述特定辅小区是指处于激活状态的辅小区。
可选的，上述特定辅小区是所有处于激活状态的辅小区。
可选的，上述特定辅小区是第一信息域包括的2比特所对应的辅小区，而其他处于激活状态的辅小区可以配置或协议规定为发送或不发送参考信号。
示例3：第一信息域包括n个比特，分别用于指示终端设备是否在n个辅小区或n个辅小区组发送参考信号，当其中一个比特指示终端设备在对应的辅小区或辅小区组发送参考信号时，终端设备在主小区也发送参考信号。n为正整数。
示例4：第一信息域包括m个比特，m大于等于2，,网络配置或协议规定终端设备在其中一个辅小区或辅小区组默认不发送参考信号，此时第一信息域指示终端设备是否在PCell和/或其他剩余的辅小区或辅小区组发送参考信号。
例如，第一信息域为辅小区比特位图(SCell bitmap)，可以配置一个SCell group在SCell bitmap对应的比特位置，实现配置终端设备在该SCell group默认不发送参考信号。
又例如，第一信息域为SCell bitmap，协议规定终端设备不在SCell bitmap中的bitmap的最高位(most significant bit，MSB)对应的Scell group发送参考信号，和/或终端设备不在SCell bitmap中的bitmap的最低位(least significant bit，LSB)对应的Scell group发送参考信号。
应理解的是，在CA场景，一个载波可以认为是一个服务小区，UE和基站在不同的服务小区传输数据可以认为是在不同的载波传输数据。
上述本申请提供的实施例中，分别从各个网元本身、以及从各个网元之间交互的角度对本申请实施例提供的通信方法的各方案进行了介绍。可以理解的是，各个网元，例如网络设备和终端设备，为了实现上述功能，其包含了执行各个功能相应的硬件结构和/或软件 模块。本领域技术人员应该很容易意识到，结合本文中所公开的实施例描述的各示例的单元及算法步骤，本申请能够以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行，取决于技术方案的特定应用和设计约束条件。专业技术人员可以对每个特定的应用来使用不同方法来实现所描述的功能，但是这种实现不应认为超出本申请的范围。

作为另一种可选的变形，该装置可以为芯片系统。本申请实施例中，芯片系统可以由芯片构成，也可以包含芯片和其他分立器件。示例性地，该装置包括处理器和接口，该接口可以为输入/输出接口。其中，处理器完成上述处理单元1401的功能，接口完成上述收发单元1402的功能。该装置还可以包括存储器，存储器用于存储可在处理器上运行的程序，处理器执行该程序时实现上述各个实施例的方法。
与上述构思相同，如图15所示，本申请实施例还提供一种装置1500。该装置1500中包括：通信接口1501、至少一个处理器1502、至少一个存储器1503。通信接口1501，用于通过传输介质和其它设备进行通信，从而用于装置1500中的装置可以和其它设备进行通信。存储器1503，用于存储计算机程序。处理器1502调用存储器1503存储的计算机程序，通过通信接口1501收发数据实现上述实施例中的方法。
