Abstract

本申请公开了一种信号测量方法及通信装置，用于解决现有技术存在信号测量可靠性差、功耗大等技术问题。所述方法包括：在不连续接收DRX状态的不活跃时间non-active time内接收参考信号；对所述参考信号进行测量。

Description

一种信号测量方法及通信装置 技术领域
本申请涉及移动通信技术领域，尤其涉及一种信号测量方法及通信装置。
背景技术
在第五代移动通信技术(the 5th generation，5G)新空口(new radio，NR)系统中，网络设备会配置下行参考信号，用户设备(user equipment，UE)可以根据该参考信号做测量，还可以针对某些目的的测量向基站反馈测量结果，例如上报信道状态信息(channel state information，CSI)。
NR的技术协议(technical specification，TS)38.214中规定“If the UE is configured with DRX,the most recent CSI measurement occasion occurs in DRX active time for CSI to be reported”，即如果UE配置了不连续接收(Discontinuous Reception，DRX)，则UE用于上报信道状态信息(channel state information，CSI)所基于的CSI测量时机(即测量信道状态参考信号(channel state information reference signal，CSI-RS)的时机)需要位于DRX的激活时间(active time)内。也就是说，UE只需要对active time内参考信号进行信号测量，对于不位于active time的参考信号，UE不需要对该参考信号进行测量，因为UE不需要上报该参考信号的测量结果。
如果连续多个DRX周期的唤醒信号(wake-up signal，WUS)都指示UE不唤醒，即不在WUS之后对应的DRX持续时间(DRX on duration)内监听PDCCH，那么UE在该连续多个DRX周期都不会启动DRX持续时间定时器(DRX-on duration timer)，即不会进入active time，相应的，UE也不会执行CSI测量和上报。
UE长时间不测量和上报CSI将导致基站长时间收不到UE的CSI，严重影响WUS的可靠性。并且，UE长时间睡眠被唤醒后，最开始上报的CSI是上一次active time测量的CSI结果，而上一次active time与当前上报时机的时间间隔较长，信道状态可能已经发生变化，因此会造成CSI不准确，导致UE唤醒后的一段时间性能较差。并且，上报不准确的CSI是没必要的，浪费了UE的功耗。另外，针对波束管理(beam management)，如果UE长时间不上报CSI，会导致基站无法更新发送波束(beam)，造成波束故障(beam failure)，进而触发UE执行波束故障恢复(beam failure recovery，BFR)，增加了UE功耗。
由此可见，现有技术存在信号测量可靠性差、功耗大等技术问题。
发明内容
本发明实施例提供一种信号测量方法及通信装置，以提高信号测量的可靠性。
第一方面，本发明实施例一种信号测量方法，应用于用户设备UE，所述方法包括：在不连续接收DRX状态的不活跃时间non-active time内接收参考信号；对所述参考信号进行测量。也就是说，UE可以在不连续接收DRX状态的不活跃时间non-active time内接收参考信号，并对所述参考信号进行测量，这样可以使UE即便在长时间睡眠过程中或者长时间睡眠唤醒后，也可以及时得到准确的参考信号测量结果，进而保证PDCCH-WUS的可靠性、UE长时间睡眠唤醒后的性能，另外还可以避免UE长时间不上报CSI所引起CSI 波束故障，节省UE功耗。
一种可能的设计中，在DRX状态的non-active time内接收参考信号可以包括：在DRX状态的持续时间on duration之前的第一时间段接收参考信号。也就是说，UE可以在on duration之前的第一时间段执行参考信号的接收和测量，使得UE即便在长时间睡眠过程中或者长时间睡眠唤醒后，UE或者网络设备也可以及时得到准确的参考信号测量结果，进而保证PDCCH-WUS的可靠性、UE长时间睡眠唤醒后的性能，另外UE还可以基于non-active time内的参考信号进行波束管理，避免beam failure，节省UE功耗。
在一种可能的设计中，所述第一时间段可以是周期性的，例如所述第一时间段可以按照设定的时间间隔周期性地出现，其中所述第一时间段的出现周期为DRX周期或WUS周期的N倍，其中N为正整数。通过将第一时间段进行周期性的设计，可以保证UE即便长期进入睡眠状态，仍然能够定期测量参考信号，获得准确的信号测量结果。
在一种可能的设计中，所述第一时间段可以是非周期性的，例如，在所述UE连续睡眠M个DRX周期后的第1个DRX周期的on duration之前的第一时间段接收参考信号，其中M为大于或者等于0的整数。这样，可以保证UE在连续睡眠一段时间后，可以及时测量参考信号，获得准确的信号测量结果。
在一种可能的设计中，所述第一时间段可以位于所述on duration之前、且位于所述on duration对应的唤醒信号WUS检测时间之后。这样，可以更好地保证UE长时间睡眠后在on duration唤醒时的性能。
在一种可能的设计中，所述第一时间段位于：所述on duration对应的WUS检测时间之前。这样，可以更好地保证PDCCH-WUS的可靠性。
在一种可能的设计中，所述方法还包括：确定参考信号资源，在所述参考信号资源上接收所述参考信号；其中，所述参考信号资源的时域位置位于所述DRX状态的non-active time内。
在一种可能的设计中，所述参考信号资源可以包括：位于所述on duration对应的WUS检测时机之前或者之后的X个参考信号资源，所述X为正整数。此方式将参考信号资源和WUS检测时机相关联，可以更好地保证PDCCH-WUS的可靠性或者UE长时间睡眠后在on duration唤醒时的性能。
在一种可能的设计中，所述X个参考信号资源位于所述on duration对应的WUS检测时机之前，且所述X个参考信号资源中至少存在一个参考信号资源的结束时刻与所述WUS检测时机的开始时刻之间的时间间隔大于或等于第一阈值。这样，可以更好地保证PDCCH-WUS的可靠性。
在一种可能的设计中，所述X个参考信号资源位于所述on duration对应的WUS检测时机之后，且所述X个参考信号资源中至少存在一个参考信号资源的起始时刻与所述WUS检测时机的结束时刻之间的时间间隔大于或等于第二阈值。这样，可以更好地保证UE长时间睡眠后在on duration唤醒时的性能，并且有利于节省UE功耗。
在一种可能的设计中，所述X个参考信号资源位于所述on duration之前，且所述X个参考信号资源中至少存在一个参考信号资源的结束时刻与所述on duration的起始时刻之间的时间间隔大于或等于第三阈值。这样，可以更好地保证UE长时间睡眠后在on duration唤醒时的性能。
在一种可能的设计中，所述方法还可以包括：在所述on duration之前或者所述on  duration内向网络侧上报测量结果，其中所述测量结果是基于对所述参考信号进行测量所得到的测量结果；或，在确定WUS信号指示所述UE在所述WUS信号对应的on duration唤醒后，在所述WUS信号对应的on duration之前或者所述WUS信号对应的on duration内向网络侧上报测量结果，其中所述测量结果是基于对所述参考信号进行测量所得到的测量结果；或，在所述UE连续睡眠M个DRX周期后的第1个DRX周期的on duration之前或者所述第1个DRX周期的on duration内向网络侧上报测量结果，其中所述测量结果是基于对所述参考信号进行测量所得到的测量结果。也就是说：当UE处于non-active time时，也可以对参考信号进行测量上报，或者，UE仍然在active time内上报测量结果，但是测量参考信号是在non-active time内执行，这样可以使UE即便在长时间睡眠过程中或者长时间睡眠唤醒后，网络侧也可以及时得到准确的参考信号测量结果，进而保证PDCCH-WUS的可靠性、UE长时间睡眠唤醒后的性能，另外还可以避免UE长时间不上报CSI所引起CSI波束故障，节省UE功耗。
另一种可能的设计中，在DRX状态的non-active time内接收参考信号，还可以包括：在特定on duration内接收参考信号，其中至少一个所述特定的on duration位于DRX状态的non-active time内。也就是说，当至少一个特定on duration在non-active time内时，就可以实现UE在non-active time内执行参考信号的测量和上报，即便在UE长时间睡眠过程中或者长时间睡眠唤醒后，网络设备或UE也可以及时得到准确的参考信号测量结果，进而保证PDCCH-WUS的可靠性、UE长时间睡眠唤醒后的性能，另外UE还可以基于non-active time内的参考信号进行波束管理，避免beam failure，节省UE功耗。
在一种可能的设计中，所述特定on duration可以是周期性的，例如所述特定on duration按照设定的时间间隔周期性地出现。其中，所述特定on duration的出现周期可以为DRX周期的P倍，其中P为正整数。通过将特定on duration进行周期性的设计，可以保证UE即便长期进入睡眠状态，仍然能够定期测量参考信号，获得准确的信号测量结果。
在一种可能的设计中，所述特定on duration可以是非周期性的，例如所述特定on duration为所述UE连续睡眠M个DRX周期后的第1个DRX周期的on duration。这样，可以保证UE在连续睡眠一段时间后，仍然可以及时(即在特定on duration)测量参考信号，获得准确的信号测量结果。并且可以减少UE测量频率，节省UE功耗。
在一种可能的设计中，所述方法还包括：在所述特定on duration内向网络侧上报测量结果。具体的，UE可以针对某些目的的测量向基站反馈测量结果，例如上报CSI。这样，使得网络侧可以及时获得准确的信号测量结果，进一步提高通信质量。
在一种可能的设计中，为了提高方案的灵活性，本发明实施例中的所述DRX周期可以为DRX长周期，也可以DRX短周期，这里不做限制。
在一种可能的设计中，所述方法还可以包括：确定上报资源，在所述上报资源上向网络侧上报测量结果，其中所述测量结果是基于对所述参考信号进行测量所得到的测量结果；其中，所述上报资源包括以下几种资源中的至少一种：所述网络侧配置或指示的周期性物理上行控制信道PUCCH资源；已经激活后的、且尚未被去激活的半持续性PUCCH资源；已经激活后的、且尚未被去激活的半持续性物理上行共享信道PUSCH资源；由无线资源控制RRC信令配置的、且尚未被释放的PUCCH或PUSCH资源。也就是说：参考资源可以是原先配置好的，也可以是额外为在不连续接收DRX状态的不活跃时间non-active time的信号测量配置的，提高了方案的灵活性。

在一种可能的设计中，所述第一时间段按照设定的时间间隔周期性地出现，所述第一时间段的出现周期为DRX周期或WUS周期的N倍，其中N为正整数。

在一种可能的设计中，所述第一时间段位于：所述on duration之前、且位于所述on duration对应的唤醒信号WUS检测时间之后；或者，所述第一时间段位于：所述on duration对应的WUS检测时间之前。
在一种可能的设计中，所述参考信号资源可以包括：位于所述on duration对应的WUS检测时机之前或者之后的X个参考信号资源，所述X为正整数。
在一种可能的设计中，所述X个参考信号资源可以位于所述on duration对应的WUS检测时机之前，且所述X个参考信号资源中至少存在一个参考信号资源的结束时刻与所述WUS检测时机的开始时刻之间的时间间隔大于或等于第一阈值；或者，所述X个参考信号资源可以位于所述on duration对应的WUS检测时机之后，且所述X个参考信号资源中至少存在一个参考信号资源的起始时刻与所述WUS检测时机的结束时刻之间的时间间隔大于或等于第二阈值；或者，所述X个参考信号资源可以位于所述on duration之前，且所述X个参考信号资源中至少存在一个参考信号资源的结束时刻与所述on duration的起始时刻之间的时间间隔大于或等于第三阈值。

具体实施方式
为了使本发明实施例的目的、技术方案和优点更加清楚，下面将结合附图对本发明实施例作进一步地详细描述。
为了便于理解本发明实施例，下面对本申请的应用场景进行说明。
目前，第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)标准组织目前正在制定第5代蜂窝移动通信系统(5th Generation，5G)的协议标准，5G也被称为新空口(New Radio，NR)。与长期演进(Long Term Evolution，LTE)系统相比，NR支持更大的传输带宽，更多的收发天线阵列，更高的传输速率以及更灵活、粒度更小的调度机制。虽然基于上述特性NR提供更多的适用范围，但是却极大的增加了终端设备的功耗负担。为了降低终端设备的功耗，3GPP在新空口(new radio，NR)版本16(Release-16)版本中引入了功耗节省(Power saving)研究课题，其目的是研究使终端设备可在各种状态下(包括连接(connection)态，空闲态，以及非激活态)下可能的降功耗方案，其中，在连接态如何节省终端设备功耗是一个研究重点。
目前，连接态下节省终端设备功耗的一种可能方案是：为无线电资源控制(radio Resource control，RRC)连接态的用户设备(user equipment，UE)配置连接态下的不连续接收(connected-discontinuous reception，C-DRX)，即C-DRX(Connected-Discontinuous Reception)，在本文中又简称为不连续接收。目的是为了使UE每隔一定的周期进入DRX的持续时间(on duration)去监听物理下行控制信道(physical downlink control channel，PDCCH)，而在其他时候则可以进入睡眠状态，不去监听PDCCH，从而达到节省UE功耗的目的。
当UE配置了DRX时，UE的状态可以分为：不连续接收的激活态或活跃态(DRX active)、不连续接收的非激活或非活跃(DRX non-active)态，UE处于DRX Active态的 时间称为DRX的激活时间或者活跃时间(DRX active time)，UE处于DRX non-active态的时间称为DRX的非激活时间或者不活跃时间(DRX active time)。UE处于DRX active time时，UE会持续监听PDCCH。如果UE离开DRX Active态，即进入睡眠状态(DRX non-active)，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 Time：DRX持续时间定时器(DRX-on durationTimer)，DRX非激活定时器(DRX-inactivity timer)，DRX下行重传定时器(DRX–retransmission timer DL)，DRX上行重传定时器(DRX-retransmission timerUL)，随机接入竞争解决定时器(RA-contention resolutiontimer)。此外，DRX active time还可以包括其他情况，例如：UE在PUCCH上发送了调度请求(scheduling request，SR)之后的等待期间、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期间。
应理解的是，当UE处于DRX active time，UE会持续监听PDCCH。如果离开了DRX active time，则UE不去监听PDCCH，即UE在所述non-active time内不监听PDCCH。
具体的，所述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)，PUSCH传输功率控制无线网络临时标识(transmit power control-PUSCH-RNTI，TPC-PUSCH-RNTI),和SRS传输功率控制无线网络临时标识(transmit power control-SRS-RNTI，TPC-SRS-RNTI)。
UE在non-active time，是不监听如上所述PDCCH的。但是，UE仍然监听其他PDCCH，所述其他PDCCH可以是如下的一种无线网络临时标识(radio network temporary identifier,RNTI)加扰的：功率节省RNTI(power saving RNTI，PS-RNTI)、系统信息RNTI(system information RNTI,SI-RNTI),寻呼RNTI(Paging RNTI，P-RNTI)、随机接入RNTI(random access RNTI,RA-RNTI),暂时C-RNTI(Temporary C-RNTI，TC-RNTI)等。
图1表示配置了DRX之后的UE状态示例。UE在DRX周期的开始时刻会首先进入on duration，同时开启Drx-on duration timer，进入DRX active态，如果在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-inactivity timer。UE将一直处于DRX-Active态直到DRX-inactivity timer超时，或者UE收到相关的媒体接入控制(medium access control，MAC)控制元素(control element，CE)信令使该DRX-inactivity timer提前停止。现有技术中，DRX-inactivity timer是在指示新的数据传输的PDCCH之后第一个符号启动或重启，例如图2所示，图中PDCCH调度新的PDSCH传输。
在UE的power saving研究课题中，还引入了一个新的功率节省信号(power saving signal)。目前一般认为该power saving signal在on duration之前发送，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。该power saving signal基于PDCCH信道。
根据不同的功能可以将power saving signal分类为唤醒(wake-up，WUS)信号和睡眠 (go-to-sleep，GTS)信号：(1)、如果power saving signal指示唤醒(wake-up)功能，即表示唤醒信号(wake-up signal，WUS)，又称为基于PDCCH的唤醒信号(PDCCH-based wake-up signal，PDCCH-WUS)，UE可以通过是否检测到WUS决定是否在对应的on duration唤醒，从而进入active态。如图3所示，如果检测到WUS，则UE开启DRX-on duration timer，在DRX cycle的on duration唤醒，进入active态监听PDCCH，如果未检测到该WUS，则UE不开启DRX-on duration timer，即UE不需要在该DRX cycle唤醒，而进入睡眠状态节省功耗。(2)、如果power saving signal指示睡眠(go-to-sleep)功能，即表示睡眠信号(go-to-sleep signal，GTS signal)，又称为基于PDCCH的睡眠信号(PDCCH-based go-to-sleep signal，PDCCH-GTS signal)，则UE在检测到该GTS signal的时候不开启DRX-on duration timer从而进入或保持睡眠状态，在未检测到该GTS signal的时候默认开启DRX-on duration timer，进入active态监听PDCCH。(3)、此外，power saving signal也可以既指示wake-up功能也指示go-to-sleep功能，例如通过DCI中的1比特(bit)的指示域指示UE唤醒进入On Duration监听PDCCH或者是指示UE不唤醒，例如指示域的值为“0”则指示UE不唤醒，指示域的值为“1”则指示UE唤醒。
目前，在标准的会议讨论中，已经同意位于on duration之前的基于PDCCH的功率节省信号具有唤醒功能，即PDCCH-WUS。如果PDCCH-WUS指示UE唤醒，则UE在PDCCH-WUS对应的on duration到来时启动DRX-on duration timer，进入active态监听PDCCH，否则，UE不启动DRX-on duration timer，即不进入active态，不监听PDCCH(这里假设没有其他原因使UE处于active态)。
需要说明的是，本发明实施例不限定PDCCH-WUS如何指示UE唤醒。例如，可以通过是否检测到该信号来判断是否唤醒监听PDCCH，也可以是根据PDCCH-WUS DCI中相应信息域的指示来判断是否唤醒监听PDCCH。
在NR中，网络设备会配置下行参考信号，UE可以根据该参考信号做信号测量，对参考信号做测量的目的可以有多种，例如：用于信道质量(channel quality)的测量，或者用于波束管理(beam management)，或者用于时频跟踪(time/frequency tracking)，或者用于移动性管理(例如无线资源管理(radio resource management，RRM))等。UE可以针对某些目的的测量向基站反馈测量结果，例如上报信道状态信息(channel state information，CSI)。
NR的协议TS 38.214中规定：“If the UE is configured with DRX,the most recent CSI measurement occasion occurs in DRX active time for CSI to be reported”，即如果UE配置了DRX，则用于CSI上报的测量时机(即测量参考信号的时机)需要位于DRX active time。也就是说，如果参考信号不位于DRX active time，则UE不需要对该参考信号进行测量，因为UE不需要上报该参考信号的测量结果。另外，NR的协议TS 38.321中规定：针对周期性CSI上报和半持续CSI上报，如果在上报符号之前4ms，UE不处于DRX active time，则UE不上报CSI。如果设置了CSI掩码(CSI-Mask)，且在上报符号之前4ms，drx-onDurationTimer不在运行，则UE不在PUCCH上报CSI(包括周期PUCCH上报和半持续PUCCH上报)。
根据上文中关于WUS的描述，如果连续多个DRX周期的唤醒信号WUS都指示UE不唤醒，那么UE在连续多个DRX周期都不会启动DRX-on duration timer，UE将长时间不进入active time，那么UE将长时间不执行CSI测量和上报。UE长时间不测量和上报CSI，将导致基站长时间收不到UE的CSI，会存在以下问题：
(1)、基站长时间收不到UE的CSI，因此无法得到准确的CSI，严重影响PDCCH-WUS的可靠性；
(2)、当UE长时间睡眠被唤醒后，最开始上报的CSI是上一次active time内测量的CSI结果，而上一次active time与当前上报时机的时间间隔较长，因此该CSI可能不准确，导致UE唤醒后的一段时间性能较差；
(3)、针对波束管理(beam management)场景，如果UE长时间不上报CSI，会导致基站无法更新发送波束(beam)，造成波束故障(beam failure)，进而触发UE执行波束故障恢复(beam failure recovery，BFR)，增加了UE功耗，和power saving目的相违背。
由此可见，现有技术只能在DRX active time进行参考信号的测量和上报，存在信号测量可靠性差、功耗大等的技术问题。鉴于此，本发明实施例提供一种参考信号测量方法，该方法用以实现当UE处于non-active time时，也可以对参考信号进行测量和上报，或者，UE仍然在active time内上报CSI，但是用于CSI上报的测量参考信号可以位于non-active time内，这样可以使UE即便在长时间睡眠过程中或者长时间睡眠唤醒后，也可以及时得到准确的参考信号测量结果，进而保证PDCCH-WUS的可靠性、UE长时间睡眠唤醒后的性能，另外还可以避免UE长时间不上报CSI所引起CSI波束故障，节省UE功耗。具体实现方案将在后文详细介绍。

实施例一
参见图4A，为本发明实施例中的一种信号测量方法的流程图，该方法包括：
S401、网络设备在DRX状态的on duration之前的第一时间段向UE发送参考信号。
在本发明实施例中，第一时间段在on duration之前，是指第一时间段位于on duration和该on duration相邻的上一个on duration之间。作为一种可选的实施方式，第一时间段的长度不超过设定长度。此外，第一时间段和该on duration的时间间隔不超过于设定阈值，这样可保证第一时间段位于on duration和该on duration相邻的上一个on duration之间，例如不会和上一个on duration重叠。
在本发明实施例中，UE在该on duration内可以是处于active态，也可以是处于non-active态，本发明实施例这里不做限制。UE在该on duration相邻的上一个on duration内可以是处于active态，也可以是处于non-active态，本发明实施例这里不做限制。例如，参见图5，图5中示出了三个DRX周期，在这三个DRX周期中的每个DRX周期的on duration之前都存在第一时间段，网络设备在每个第一时间段内都向UE发送参考信号，相应的，UE在每个第一时间段内接收网络设备发送的参考信号。在图5中，第一个on duration用虚线表示，表征UE在第一个on duration之前未收到WUS或者收到的WUS指示UE在该on duration到来时不唤醒，DRX-on duration timer在第一个on duration未开启，UE在第一个on duration处于non-active态，不监听PDCCH，而第二、三个on duration用实线表示，表征UE在第二、三个on duration处于active态，监听PDCCH。
在一些可能的设计中，第一时间段可以按照设定的时间间隔周期性地出现，也即网络设备按照设定的时间间隔周期性地向UE发送参考信号，以使UE在每个周期对应的第一时间段内接收网络设备发送的参考信号，并对参考信号进行测量。在具体实施时，第一时间段的出现周期可以为DRX周期，或者WUS周期的N倍，其中N为正整数，当然，还可以有其他的设计方式，本发明实施例这里不做限制。通过将第一时间段进行周期性的设计，可以保证UE即便长期进入睡眠状态，仍然能够定期测量参考信号，获得准确的信号测量结果。
另一些可能的设计中，第一时间段可以是非周期性的。作为一种示例，第一时间段可以是在UE连续睡眠M个DRX周期后的第1个DRX周期的on duration之前的一段时间，其中M为大于或者等于0的整数。相应的，网络设备在UE连续睡眠M个DRX周期后的第1个DRX周期的on duration之前的第一时间段向UE发送参考信号，使得UE在连续睡 眠M个DRX周期后的第1个DRX周期的on duration之前的第一时间段测量参考信号。这样的设计，也可以保证UE在连续睡眠一段时间后，可以及时测量参考信号，获得准确的信号测量结果。
考虑到实际情况中，on duration之前还存在WUS检测时机(或者叫WUS监测时机、WUS接收时机、WUS时间窗等)，则位于on duration之前的第一时间段和WUS检测时机的位置关系，包括但不限于以下几种：第1种、第一时间段位于on duration之前、且位于WUS检测时间之后，如图6A所示。这样，可以使得第一时间段更加靠近on duration，进而可以更好地保证UE在on duration唤醒后UE的通信性能。第2种，第一时间段位于on duration之前、且位于WUS检测时间之前，如图6B所示。这样，可以使得UE在WUS之前的非激活时间段内也能够做信号测量、时频同步或者是做信号测量和上报，进而更好地保证WUS信号的可靠性。第3种，第一时间段和WUS检测时间至少部分重合。例如图6C所示，第一时间段的开始时刻在WUS检测时间之前，结束时间在WUS检测时间之后。当然，在具体实施时，还可以根据实际需求进行其他设计，本发明实施例这里不做限制。
在本发明实施例中，第一时间段可以是一个持续的时间段，例如图6A、图6B、图6C中所示的时间段，第一时间段还可以是多个子时间段构成的时间段集合，例如图6D所示。
在本发明实施例中，网络设备在发送参考信号前，需要先确定参考信号资源，然后再在确定出的参考信号资源上发送参考信号，相应的，UE需要先确定出参考信号资源，然后再在参考信号资源上接收参考信号。UE可以根据网络设备下发的信令确定参考信号资源，或者是根据预配置的协议确定参考信号资源，本发明实施例不做具体限制。
UE根据网络设备下发的信令确定参考信号资源：
具体的，网络设备可以在原先已配置的参考信号资源上发送参考信号，网络设备通过下发信令向UE指示该第一时间段。相应的，UE根据网络设备的配置或者指示确定第一时间段后，在第一时间段内已配置的参考信号资源上接收参考信号，即确定出的参考信号资源为位于第一时间段内的已配置的参考信号资源。
一种可能的设计中，参考信号资源可以和WUS检测时机(或者说WUS资源)相关联。
一种可能的关联方式为：网络设备发送参考信号的资源是位于on duration对应的WUS检测时机之前或者之后的X个参考信号资源，其中X为正整数。
例如，该X个参考信号资源位于on duration对应的WUS检测时机之前，且X个参考信号资源中至少存在一个参考信号资源的结束时刻与WUS检测时机的开始时刻之间的时间间隔大于或等于第一阈值。
例如，X个参考信号资源位于on duration对应的WUS检测时机之后，且X个参考信号资源中至少存在一个参考信号资源的起始时刻与WUS检测时机的结束时刻之间的时间间隔大于或等于第二阈值。
例如，X个参考信号资源位于on duration之前，且X个参考信号资源中至少存在一个参考信号资源的结束时刻与on duration的起始时刻之间的时间间隔大于或等于第三阈值。
其中，上述第一阈值、第二阈值、第三阈值可以是预先配置好的或预先规定好的，且第一阈值、第二阈值、第三阈值中任意两个阈值可以相等或者不等，这里不做限制。其中，第一阈值可以与如下因素中的至少一种因素有关：参考信号的处理和计算的时间、时频跟踪的处理时间、接收端波束选择的时间或CSI上报的时间。第二阈值与如下因素中的至少一种因素有关：PDCCH-WUS的解调、译码和解析的时间或WUS DCI的解析的时间。第 三阈值与如下因素中的至少一种因素有关：参考信号的处理和计算的时间、CSI处理的时间(CSI计算的时间)。
应理解，如果X大于1，则上述X个参考信号资源可以是非连续的，则X个参考信号资源的开始时刻为X个参考信号资源中第1个参考信号资源的开始时刻，X个参考信号资源的结束时刻为X个参考信号资源中第X个参考信号资源的结束时刻。
另一种可能的设计中，网络设备直接给UE配置或者向UE指示发送参考信号的参考信号资源，其中参考信号资源的时域位置即为第一时间段的位置，因而网络设备可以不用告诉UE第一时间段，UE在确定参考信号资源后，直接在参考信号资源上接收参考信号。
UE根据预配置的协议确定参考信号资源：
具体的，网络设备可以在原先已配置的参考信号资源上发送参考信号，根据预配置的协议确定第一时间段，相应的，UE根据预配置的协议确定第一时间段后，在第一时间段内已配置的参考信号资源上接收参考信号。例如，所述根据预配置的协议确定的第一时间段是WUS检测时机和On Duration之间的时间段。
下面，以参考信号为CSI-RS为例，对参考信号和参考信号资源进行详细说明。(接下来的描述中，除非有特殊说明外，参考信号均指CSI-RS)。
1、参考信号的用途，包括但不限于信道质量(channel quality)的测量、波束管理(beam management)的测量，或者用于时频跟踪(time/frequency tracking)的测量，或者用于移动性管理的测量等。
其中，参考信号用于信道质量的测量，信道质量包括但不限于信道质量指示(channel quality indicator，CQI)、预编码矩阵指示(Precoding matrix indicator，PMI)、秩指示(rank indicator，RI)、CSI-RS资源指示(CSI-RS Resource indicatior，CRI)或层指示(layer indicator，LI)。
参考信号用于波束管理，可以是UE基于该参考信号计算L1-RSRP。
参考信号用于时频跟踪，可以是参考信号的功能设置为跟踪参考信号(tracking reference signal，TRS)。时频跟踪也可以称为时频同步，UE接收下行参考信号以进行时频偏同步，防止终端设备因为长时间休眠造成系统的时钟和工作频率与网络设备出现偏差。
参考信号用于移动性管理，可以是无线资源管理(radio resource management，RRM)。
一般的，网络设备通过在CSI上报配置(CSI-ReportConfig)中配置上报量(report quantity)来指示所关联的参考信号资源的用途。例如，如果将上报量配置为CQI/PMI/RI/CRI/LI中的至少一种，表示所关联的参考信号资源用于测量信道质量。如果将上报量配置为L1-RSRP(例如，配置为cri-RSRP或ssb-Index-RSRP)，表示所关联的参考信号资源用于波束管理。
此外，针对时频跟踪和接收端波束选择，由于不需要UE上报测量结果，所以网络设备会配置上报量为不上报(上报量配置为NULL)。此外网络设备在配置参考信号资源的时候，会在参考信号资源配置IE中包含一些参数，来指示所配置的参考信号资源用于时频跟踪或波束管理。例如，在配置NZP-CSI-RS-ResourceSet IE时，包含参数trs-Info参数，和repetition参数。如果trs-Info设置为真(true)，则表示该参考信号资源用于时频跟踪。Repetition参数可以设置为开启(on)或关闭(off)。如果repetition参数设置为开启(on)，表示该NZP-CSI-RS-ResourceSet IE所配置的资源集合中的所有参考信号资源上发送的参考信号采用相同的下行空域传输滤波器和相同的端口数。当参考信号资源对应的参数repetition设置为开启，且相应的上报量配置为NULL时，所述参考信号资源的实际用途即 为接收端波束选择。
此外，当参考信号资源配置repetition为开启时，也可以在相应的上报配置中配置上报量为L1-RSRP，即，UE既做接收端波束测量和选择，也需要上报测量结果。
此外，针对移动性管理，网络设备会使用与CQI测量/波束管理/时频跟踪相互独立的信令配置用于移动性管理的参考信号资源。例如，网络设备通过CSI-ResourceConfig的信令配置用于CQI测量/波束管理/时频跟踪的参考信号资源，通过CSI-RS-ResourceConfigMobility的信令配置用于移动性管理的参考信号资源。
需要说明的是，后文以“CQI测量”或“测量CQI”来表示对信道质量的测量，所述信道质量的测量是为了得到如下至少一种测量参数：CQI/PMI/RI/CRI/LI。需要说明的是，后文用“CSI测量”或“测量CSI”，表示CQI测量，或波束测量。
2、参考信号的时域特征。包括但不限于以下有两种实现方式：
方式1：有固定的周期。
首先，定义所述参考信号的周期：网络设备在参考信号资源上发送所述参考信号。如果一个on duration之前存在1个或多个所述参考信号资源，定义一个时间段，该时间段位于一个on duration之前(以及上一个on duration之后)，所述时间段包括该on duration之前的(以及上一个on duration之后的)所述一个或多个参考信号资源，则所述参考信号的周期等于相邻的两个所述时间段的起始时刻(或结束时刻)之间的时间间隔。如下描述中，该时间段称为第一时间段。
一种可能的设计方式是，所述第一时间段的周期可以是C-DRX周期或WUS周期的N倍(N≥1)。
同样的，先明确WUS周期的含义：由于on duration之前可能存在1个或多个WUS监听时机，所以定义一个时间段，所述时间段包括一个on duration之前的(以及上一个on duration之后的)所述一个或多个WUS监听时机，则所述WUS的周期等于相邻的两个所述时间段的起始时刻(或结束时刻)之间的时间间隔。注意，这里假设不考虑DRX短周期。
在具体实施时，WUS周期可以等于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on duration，on duration前面才有WUS监听时机，该WUS同时指示后面的两个DRX周期是否都唤醒或都不唤醒。其中，所述C-DRX周期为DRX长周期。
当N＝1时，表明每个on duration之前，都有所述CSI-RS。不管WUS指示UE是否唤醒监听PDCCH，即不管UE是否启动DRX-on duration timer，UE都可以对该CSI-RS执行测量。
当N>1时，表明并不是每个on duration之前，网络设备都发送所述CSI-RS，而是在每隔N-1个on duration之后的on duration之前，网络设备才发送所述CSI-RS。这样，可以节省网络设备资源和功耗。即使WUS指示UE不唤醒，UE也不需要每个on duration之前都执行测量，而是每隔N-1个on duration，UE才在之后的on duration之前对参考信号执行测量。这种方式比较适用于信道状态变化较慢的场景，比如UE处于静止或移动性较低的场景。如果WUS指示UE不唤醒，且一个on duration之前没有所述参考信号，则UE不执行测量，可以回到睡眠状态，节省UE功耗。所以N>1可以在UE功耗和UE性能之间取得良好折衷。如下图7所示，为N＝2的示例，即CSI-RS的周期是C-DRX周期的2 倍。
方式2：没有固定的周期。
一种可能的设计是，在UE连续睡眠M个DRX cycle之后，不管WUS指示UE在第M+1个DRX周期(即连续睡眠M个DRX cycle之后的第1个DRX cycle)是否唤醒监听PDCCH，UE假设第M+1个DRX周期的on duration之前的一段时间内，参考信号资源一定存在，参考信号一定发送。
在一种可能的实现方式中，在UE连续睡眠M个DRX cycle之后，UE才假设on duration之前存在所述参考信号，在UE睡眠的这M个DRX周期中，UE不假设或不期待参考信号存在。从而，作为网络设备，如基站，基站可以暂时不发送参考信号，节省资源开销和基站功耗。
这里的DRX周期可以为DRX为DRX长周期，即UE连续睡眠M个DRX长周期，也可以为DRX为DRX短周期，即UE连续睡眠M个DRX短周期，其中M为大于或者等于0的整数。
M的大小，可以由网络配置，配置信令可以是RRC信令、MAC CE信令或物理层信令，这里不做限定。另外，M的大小，也可以是协议预先规定好。
当WUS指示UE唤醒时，UE启动DRX-on duration timer，进入active time，UE可以在active time内执行CSI测量和CSI上报。所以，当连续多个WUS都指示UE唤醒时，网络不需要配置所述CSI-RS，UE也不需要在on duration之前执行测量和CSI上报。只有当UE睡眠了一段时间之后，信道条件可能发生变化，此时即使UE仍然不需要唤醒去收发数据，但需要执行时频跟踪和测量CSI，然后上报CSI，使网络设备及时的获得更准确的CSI，有助于PDCCH-WUS的可靠性，使网络设备选择更加合适的发送波束。所以，本方式下，UE在连续睡眠M个DRX周期之后，即使下一个WUS仍然指示UE睡眠，但UE需要对on duration之前的WUS执行测量，此外，根据网络的配置，UE决定是否上报测量结果，即是否上报CSI。另外，在UE在连续睡眠M个DRX周期之后，如果下一个WUS指示UE唤醒，由于UE在on duration之前执行了测量，例如执行了时频跟踪/波束测量/CQI测量，或者既执行了测量又上报了CSI，或者在on duration之前执行测量且在on duration内上报测量结果，则在UE唤醒之后，网络设备可以更及时的获取到UE的准确的CSI，有助于UE性能的提升。
应理解，没有固定的周期，也可以理解成参考信号资源是非周期的，由特定事件进行触发。该特定事件为：UE连续M个DRX周期睡眠。UE一旦判断出(检测到)已经连续M个DRX周期都没有唤醒，则UE假设所述参考信号资源发送。
例如，参照图8，在UE连续睡眠M＝2个DRX长周期之后，UE假设之后的1个DRX周期的on duration之前的一段时间内，参考信号一定发送。相应的，UE连续睡眠M＝2个DRX长周期之后的第一个DRX周期的on duration之前的一段时间内，存在CSI-RS资源。
当UE连续睡眠M个DRX周期之后的第M+1个DRX周期，如果WUS指示UE仍然不唤醒，则UE不启动DRX-on duration timer，但UE在这DRX周期的on duration之前，可以针对所述参考信号资源执行测量。所以，在UE和网络设备对“连续睡眠M个DRX周期”这件事进行计数时，不包括所述第M+1个DRX周期，而从下一个DRX周期重新开始计数，即从第M+1个DRX周期之后从0开始计数。如图9所示，为M＝1时的示例。
3、参考信号资源的配置和触发方式，包括显性方式和隐性方式两大类。
首先，介绍显性方式。
显性方式1、网络设备通过配置一个窗(可以理解成上文中的第一时间段)，除了DRX active time，只有窗内的参考信号，UE才假设存在。
即，网络设备配置了一个或多个参考信号资源集合(e.g.,CSI-RS resource set(s))，每个参考信号资源集合又包括一个或多个参考信号资源(CSI-RS resources)。
当UE处于激活时间时，网络设备配置的参考信号资源正常发送。此外，如果网络设备配置的参考信号资源刚好位于所述窗内，UE也假设参考信号资源发送。
如果网络设备配置的参考信号资源位于所述窗以外，并且UE不处于激活时间，UE不能假设该参考信号资源一定存在。作为一种可能的实现方式，网络设备可以不发送该参考信号资源，以节省资源开销。
即：所述窗内的参考信号资源即为所述参考信号资源。也可以理解成，所述参考信号资源是已经配置好的参考信号资源中的一部分，网络设备通过配置窗的形式来实现对所述参考信号资源时域位置的配置。
其中，已经配置好的参考信号资源，包括：
(1)周期性CSI-RS。
(2)半持续CSI-RS：只有MAC CE信令激活半持续CSI-RS资源集合之后，UE才能假设所述窗内的参考信号资源存在。如果该半持续CSI-RS资源被去激活了(deactivated)，所述窗内不存在所述参考信号资源。
(3)即包括周期性CSI-RS，也包括半持续CSI-RS。
UE假设所述窗内的周期性CSI-RS资源一定发送。
在MAC CE信令激活半持续CSI-RS资源之后，UE假设所述窗内的半持续CSI-RS资源一定发送。如果该半持续CSI-RS资源被去激活了(deactivated)，所述窗内只存在周期性CSI-RS资源。
如上文中所述的，参考信号资源可以是C-DRX周期的N倍，那么在此处，可以理解成，所述窗的周期可以是C-DRX周期的N倍。
例如，参见图10，网络设备已经配置了周期性CSI-RS资源，除了active time，在配置的所述窗内，UE假设周期性CSI-RS资源也发送。
在本发明实施例中，窗的配置方式，包括但不限于以下几种：
配置窗方式1：配置窗的长度，周期，和时间偏移等参数。
示例性的，窗的长度的单位可以为：时隙，微时隙，符号，子帧，毫秒(ms)等。窗的周期的单位可以为：时隙，微时隙，子帧，毫秒(ms)，秒(s)等。时间偏移的单位可以为：时隙，微时隙，符号，子帧，毫秒(ms)等。
时间偏移的单位和周期的单位可以相同。
配置参数中可以包括1个周期参数和1个时间偏移参数，配置参数中也可以包括1个周期参数和多个时间偏移参数，这里不做限制。
当有多个时间偏移参数时，不同时间偏移参数的单位可以不同。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。
如上描述，所述窗的周期可以是C-DRX周期或WUS周期的N倍(N≥1)。这里的DRX周期可以表示DRX长周期(long DRX cycle length)，也可以表示DRX短周期(short  DRX cycle length)。
通过周期和时间偏移参数，然后根据一定的预定义规则，或者按照一定的计算公式，可以计算出每个窗的起始时刻所在的时域位置，例如，窗的起始时刻所在的系统帧号(SFN,system frame number)，以及窗的起始时刻在一个帧中的具体子帧，或时隙，或符号。以下为两种具体的示例：
示例1、
网络设备配置所述窗的周期，和2个时间偏移。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。本例中，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。
则所述窗的起始时刻所在的系统帧号(System frame number，SFN)和子帧(subframe)可以由如下公式确定：
[(SFN×10)+subframe number]modulo T＝T_offset；
然后，再根据所述窗的时隙偏移就可以确定所述窗的起始时刻在确定的子帧中的具体时隙。
例如，网络设备可以配置第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所述窗的起始时刻在确定的时隙中所在的具体符号。
示例2、
网络设备配置所述窗的周期，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。
则所述窗的起始时刻所在的SFN和所确定的帧中的时隙编号
Figure PCTCN2019109718-appb-000001
由如下公式确定：
Figure PCTCN2019109718-appb-000002
其中，
Figure PCTCN2019109718-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 PCTCN2019109718-appb-000004
表示SCS为μ的一个帧中的时隙编号。
例如，网络设备可以配置第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所述窗的起始时刻在确定的时隙中所在的具体符号。
通过本实施方式，实现任意配置所述窗的位置的效果，可以提高方案的灵活性。
配置窗方式2：配置窗的长度，和相对时间偏移等参数。
所述相对时间偏移可以是所述窗的起始时刻和第一时域位置之间的时间偏移，或所述窗的结束时刻和第一时域位置之间的时间偏移。
一种可能的实现方式，所述第一时域位置是on duration的起始时刻。另一种可能的实现方式，所述第一时域位置是on duration之前的WUS监听时机。再一种可能的实现方式，所述第一时域位置是on duration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。
当WUS监听时机只占据一个正交频分复用(orthogonal frequency division multiplexing，OFDM)符号时，所述第一时域位置可以是WUS所在符号，或WUS所在符号的起始时刻或结束时刻，这里不做限制。
当WUS监听时机占据多个OFDM符号或占据多个时隙时，所述第一时域位置可以是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，这里不做限制。
例如，参见图11所示，为网络设备配置窗的长度、所述窗与on duration的起始时刻之间的时间偏移的一种示例，在该例中，窗位于在WUS监听时机之后。
配置窗方式3、配置1个或2个时间偏移参数。
(1)、配置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所述窗的起始时刻(或结束时刻)，则所述窗的结束时刻(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，这里不再赘述。
可选的，所述1个时间偏移为相对于预设时域位置的偏移。
可选的，所述预设时域位置为on duration的起始时刻，即所述窗的结束时刻为on duration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所述窗的起始时刻。
可选的，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on duration的起始时刻的偏移。
可选的，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on duration的起始时刻的偏移。
(2)、配置2个时间偏移参数，通过所述2个时间偏移参数确定所述窗。
可选的，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。
可选的，所述2个时间偏移参数为相对不同预设时域位置的偏移。
在本发明实施例中，DRX长周期、DRX短周期的关系，包括但不限于以下几种：
(1)、DRX长周期的on duration之前和DRX短周期的on duration之前都存在有所述窗。这样，当UE进入DRX短周期，所述窗的周期变短。也可以理解成，所述窗没有固定的周期。
作为一种可能的实现方式，DRX长周期的on duration之前才存在有所述窗，DRX短周期的on duration之前不存在有所述窗。
可选的，如果DRX短周期的on duration和DRX长周期的on duration重叠，并且此时DRX短周期定时器(drx-shortCycleTimer)正在运行，表明UE当前处于DRX短周期，此时可以规定，这样的on duration之前也有所述窗。这样，所述窗有固定的周期，即时长等于1个DRX长周期的时长的整数倍；
可选的，如果DRX短周期的on duration和DRX长周期的on duration重叠，并且此时DRX短周期定时器(drx-shortCycleTimer)正在运行，表明UE当前处于DRX短周期，此时可以规定，这样的on duration之前不存在所述窗。这样，所述窗可能没有固定的周期，会存在某些场景，两个相邻的所述窗之间的时长大于1个DRX长周期的时长。
下面介绍一种特殊的显性指示方案：UE假设WUS之后或者之前的X个CSI-RS资源一定发送。X的大小，可以通过网络配置或指示，例如RRC信令，MAC CE信令，或物理层信令。X的大小也可以通过协议预定义。X大于或等于1。
作为一种可能的实现方式，X个参考信号资源位于on duration对应的WUS检测时机 之前，且X个参考信号资源中的至少一个参考信号资源的结束时刻与WUS检测时机的开始时刻之间的时间间隔大于或等于第一阈值。
作为一种可能的实现方式，X个参考信号资源位于on duration对应的WUS检测时机之后，且X个参考信号资源中的至少一个参考信号资源的起始时刻与WUS检测时机的结束时刻之间的时间间隔大于或等于第二阈值。示例性地，所述X个CSI-RS资源的起始时刻(起始符号)与WUS监听时机的结束时刻(结束符号)之间的时间间隔大于或等于一个设定阈值。可选的，所述设定阈值为0。可选的，所述设定阈值大于或等于PDCCH-WUS的解调、译码和解析的时间，或WUS DCI的解析的时间。即，UE假设，在WUS监听时机的结束时刻算起的设定阈值之后的X个CSI-RS资源一定发送。这样，可以实现，当解析出WUS指示UE唤醒监听PDCCH后，UE才接收所述参考信号，并执行参考信号的测量、计算和上报测量结果，如果解析出WUS指示UE不唤醒，UE可以不接收所述参考信号，可以节省UE功率。该功能可以基于网络配置，或协议预先定义。可选的，UE假设从WUS监听时机之后的第一个CSI-RS资源算起一共X个CSI-RS资源一定发送。
作为一种可能的实现方式，X个参考信号资源位于on duration之前，且X个参考信号资源中的至少一个参考信号资源的结束时刻与on duration的起始时刻之间的时间间隔大于或等于第三阈值。示例性地，所述X个CSI-RS资源存在至少一个参考信号资源的的结束时刻(结束符号)与on duration的起始时刻之间的时间间隔大于或等于一个设定阈值。可选的，所述设定阈值为0。可选的，所述设定阈值大于或等于CSI处理和CSI计算的时间。这样，可以实现，当UE唤醒后在On Duration内的第一个CSI上报资源到来时，UE已经准备好了基于所述参考信号资源计算得出的测量结果，有利于UE快速上报最新的CSI，有助于提升UE性能。可选的，UE假设从on duration的起始时刻之前的第一个CSI-RS资源算起往前数一共X个CSI-RS资源一定发送。
可以理解的是，这里假设，所述参考信号资源是已经配置好的。
作为一种可能的实现方式，所述已经配置好的参考信号资源是周期性的参考信号资源。例如，网络设备已经配置好了1个或多个CSI-RS资源集合，时域特征为周期性资源。
作为一种可能的实现方式，所述已经配置好的参考信号资源是被激活之后的、尚未被去激活(deactivated)的半持续(semi-Persistent)的参考信号资源。
作为一种可能的实现方式，所述已经配置好的参考信号资源包括周期性的参考信号资源，和被激活之后的、尚未被去激活(deactivated)的半持续(semi-Persistent)的参考信号资源。
作为一种可能的实现方式，所述参考信号资源包括Y个CSI-RS资源，分别具有不同的资源编号，例如非零功率CSI-RS资源编号(Non-zero power CSI-RS ResourceID，NZP-CSI-RS-ResourceID)。每个具有相同编号的CSI-RS资源发送了X次，即X个周期。可选的，Y＝1，或Y>1。作为一种可能的实现方式，Y＝X。
作为一种可能的实现方式，网络设备可以配置或指示所述Y个CSI-RS资源所对应的资源编号。例如，当UE被配置的CSI-RS资源个数大于Y时，即UE有多于Y个的CSI-RS资源编号时，网络设备需要配置或指示所述Y个CSI-RS资源所对应的资源编号。
作为一种可能的实现方式，所述X个CSI-RS资源分别对应X个不同的资源编号，不同资源编号的CSI-RS资源只发送1次，即1个周期。
作为一种可能的实现方式，网络设备配置或指示所述X个CSI-RS资源所对应的资源 编号。
作为一种可能的实现方式，网络设备配置或指示Z个CSI-RS资源集合的编号，分别对应已经配置好的Z个CSI-RS资源集合。所述Z个CSI-RS资源集合中的每一个CSI-RS资源都发送X次，即X个周期。
作为一种可能的实现方式，网络设备配置或指示Z个CSI-RS资源集合的编号，并且从这Z个CSI-RS资源集合中配置或指示一共W个CSI-RS资源，所述Z个CSI-RS资源集合中的W个CSI-RS资源每个都发送X次，即X个周期。例如，这Z个CSI-RS资源集合中，分别指示其中的Y1，Y2，…YZ个CSI-RS资源，Y1+Y2+…+YZ＝W。网络设备分别配置或指示这W个CSI-RS资源的资源编号。可选的，Z可以等于1，或大于1.
作为一种可能的实现方式，网络设备配置或指示X个CSI-RS资源集合的编号，分别对应已经配置好的X个CSI-RS资源集合。所述X个CSI-RS资源集合中的每一个CSI-RS资源都发送1次，即1个周期。
显性方式2：参考信号资源不是已经配置好的参考信号资源，而是由于配置了WUS之后，额外配置的参考信号资源。
如果WUS指示UE不唤醒，UE只基于所述额外配置的参考信号资源执行测量，或者同时执行测量和上报CSI。如果WUS指示UE唤醒，UE进入active time，UE在active time内用来测量的参考信号资源是之前已经配置好的参考信号资源。
一种可能的实现方式，网络设备配置好所述参考信号资源后，参考信号资源即发送，即所述参考信号资源是周期性的，不需要额外的激活信令。
另一种可能的实现方式，网络设备配置好所述参考信号资源后，参考信号资源不立即发送，只有收到激活信令之后(例如MAC CE信令)，所述参考信号资源才发送，即所述参考信号资源是半持续的。网络设备可以通过去激活信令(例如MAC CE信令)去激活(deactivate)所述参考信号资源，去激活后，基站停止发送所述参考信号资源。
可选的，所述参考信号资源没有固定周期，是通过一个特定事件来触发所述参考信号资源的发送。特定事件为：UE连续M个DRX周期睡眠。UE一旦判断出(检测到)已经连续M个DRX周期都没有唤醒，则UE假设所述参考信号资源发送。即，所述参考信号资源RRC信令配置之后并不发送，只有在特定事件发生之后才发送。
一种配置所述参考信号资源的可能的实现方式，网络设备配置所述参考信号资源的时域参数，频域参数，和其他需要的参数。所述时域参数包括：周期和时间偏移。例如，周期的单位可以是时隙，时间偏移为时隙偏移。所述频域参数包括资源映射参数，用于确定参考信号的频域位置。此外，其他需要的参数包括：端口数，CDM类型，密度参数，时隙中所占用的符号位置参数，重复参数(用于判断每个OFDM符号上的参考信号是否采用了相同的空域发送滤波器和相同的端口数，用于波束管理中的UE侧波束选择)，TRS参数(用于判断参考信号是否用于时频跟踪)等。
下面例举两种可能的将参考信号资源与WUS关联配置的方案。
方案1
网络设备在配置WUS的时候配置与WUS关联的参考信号资源。与WUS关联，也可以理解成是时域上与WUS的监听时机关联。
与之前单独配置所述额外的参考信号资源不同的是，因为WUS本身会有一定的周期，所以在配置与WUS关联的参考信号资源时，不需要额外配置参考信号的周期，因为与WUS 关联，所以参考信号的周期自动与关联的WUS的周期相同。
所以，与WUS关联的参考信号资源的配置参数包括如上描述的频域参数和其他需要的参数。而不包括时域参数，即不包括：周期。
具体的，通过配置与WUS监听时机之间的时间偏移(offset)的方式将参考信号资源与WUS关联。
与WUS关联的参考信号资源可以是一个资源集合，包括一个或多个CSI-RS资源。网络配置每个CSI-RS资源与WUS的监听时机之间的时间偏移。例如，所述时间偏移的起始点为WUS的监听时机，结束点为CSI-RS资源。
当WUS的监听时机只占据一个OFDM符号时，时间偏移的起始点即为WUS所在的符号，当WUS的监听时机占据多个OFDM符号时，时间偏移的起始点为WUS监听时机的起始OFDM符号或结束OFDM符号。当一个OFDM符号的时间长度不可忽略时，所述时间偏移的起始点为WUS监听时机的起始OFDM符号(或结束OFDM符号)的起始时刻或结束时刻。时间偏移的结束点的确定方式类似，不再赘述。
可选的，时间偏移为WUS所在时隙与CSI-RS资源所在时隙之间的时隙间隔。具体地，时间偏移为WUS所在时隙的起始时刻(或结束时刻)与CSI-RS资源所在时隙的起始时刻(或结束时刻)之间的时隙间隔。
方案2
网络设备在配置WUS时，配置一个索引和时间偏移，该索引关联到一个已经配置的CSI-RS资源编号。但是，此时，该索引所关联的一个已经配置的CSI-RS资源编号所对应的参数中，周期和时隙偏移参数无效，其他参数均有效。与WUS关联的CSI-RS资源的参数即按照除周期和时隙偏移参数以外的其他参数进行配置。与WUS关联的CSI-RS资源的时域位置按照所配置的时间偏移来确定。所述时间偏移表示WUS与WUS所关联的CSI-RS资源之间的时间间隔，其具体实施与上述方案1中类似，此处不再赘述。
一种可能的实现方式，不管WUS是否发送，以及，如果WUS发送，不管WUS是指示UE唤醒还是不唤醒，与WUS的监听时机关联的参考信号资源都发送。
作为另一种可能的实现方式，只有WUS指示UE唤醒时，与WUS的监听时机关联的参考信号资源才发送。当WUS指示UE不唤醒时，与WUS的监听时机关联的参考信号资源不发送。
作为另一种可能的实现方式，只有DRX长周期的on duration之前的WUS监听时机配置关联的参考信号资源，而DRX短周期的on duration之前的WUS监听时机不配置关联的参考信号资源。
(以上为与WUS关联配置的方式)
下面，介绍隐性方式。
隐式方式一、无论WUS指示唤醒还是睡眠，WUS和on duration之间的CSI-RS一定发送，UE也可以用该CSI-RS进行测量和CSI上报，例如图12所示。
可以理解的是，这里假设，所述参考信号资源是已经配置好的。(周期性CSI-RS资源，激活后的半持续CSI-RS资源，或包括周期性CSI-RS资源和激活后的半持续CSI-RS资源，细节如之前描述，不再赘述。)
如果WUS指示唤醒，UE可以对WUS和on duration之间的CSI-RS执行测量，或者同时执行测量并且在on duration之前或on duration内进行上报CSI，有助于数据速率的提 升。
如果WUS指示睡眠，UE可以对WUS和on duration之间的CSI-RS执行测量，例如时频跟踪，波束管理的测量，CQI测量，或RRM测量。如果网络设备配置了UE上报CSI，则UE上报CSI。有助于UE维持时频跟踪和合适的接收波束。如果网络设备配置了CSI上报，则有助于基站及时获得CSI，有助于PDCCH-WUS的可靠性，例如更新PDCCH-WUS的发送波束，或针对PDCCH-WUS选择合适的编码和调制方案，聚合级别(aggregation level,AL)等参数。
隐式方式二、针对如上描述的各个方案中的所述参考信号，WUS指示唤醒时，所述参考信号才一定发送，WUS指示睡眠时，UE不能假设所述参考信号一定发送。
基于上述显性和隐式方式的具体实现，所述参考信号资源的时域位置(即如上所述的第一时间段(或所述窗)所包括的参考信号资源，或者是所述X个参考信号资源，或者是网络设备额外配置的参考信号资源，或者是WUS和on duration之间的参考信号资源)的具体实现可以是：
可选的，所述参考信号资源位于WUS监听时机的结束时刻之后。具体的，位于WUS监听时机的结束符号之后，或WUS监听时机的结束符号所在的时隙之后。
可选的，所述参考信号资源位于WUS监听时机的结束符号之后，且与WUS监听时机的结束符号之间的时间间隔大于或等于设定阈值1。
可选的，所述设定阈值1大于或等于PDCCH-WUS的解调、译码和解析的时间，或WUS DCI的解析的时间。目的为使所述参考信号资源位于UE对PDCCH-WUS解析成功之后，这样，如果WUS指示UE唤醒，则UE才对所述参考信号资源执行测量，不需要在PDCCH-WUS解析成功之前提前缓存信号。如果WUS指示UE不唤醒，UE可以不执行测量，直接进入睡眠状态。这样避免了对参考信号不必要的缓存。
可选的，所述参考信号资源位于WUS关联的on duration之前，且与on duration的起始时刻之间的时间间隔大于或等于设定阈值2。具体的，所述参考信号资源的结束时刻(结束符号)与on duration的起始时刻之间的时间间隔大于或等于设定阈值2，或所述参考信号资源的起始时刻(起始符号)与on duration的起始时刻之间的时间间隔大于或等于设定阈值2。
可选的，所述设定阈值2大于或等于CSI处理和计算的时间。这样，如果WUS指示UE唤醒，在UE启动drx-onDurationTimer时，UE已经准备好了要上报的CSI，可以在on duration内尽早的上报CSI，有助于基站尽早的获取到UE的准确的CSI，改善UE性能。
可选的，所述参考信号资源位于WUS监听时机的起始时刻(起始符号)之后。
可选的，所述参考信号资源位于WUS监听时机与on duration之间。具体的，在WUS监听时机的起始时刻(起始符号)或结束时刻(结束符号)与on duration的起始时刻之间。
可选的，所述参考信号资源位于WUS监听时机之前。例如，在WUS监听时机的起始时刻(起始符号)之前，或在WUS监听时机的起始时隙的起始符号之前。这样，UE可以在接收WUS之前，根据该参考信号资源，执行时频跟踪，或波束管理(例如接收端波束选择)。有助于PDCCH-WUS的可靠性，提高PDCCH-WUS的性能。
可以理解的是，当所述参考信号资源是已经配置好的参考信号资源时，如上描述的所述参考信号资源与WUS监听时机和on duration之间的相对时域位置，也可以理解成是，网络设备配置的所述窗与WUS监听时机和on duration之间的相对时域位置。除了激活时 间，只有在所述窗内，UE才假设参考信号存在。
可以理解的是，当所述参考信号资源是额外配置的，或与WUS关联配置的时，除了如上描述的所述参考信号资源与WUS监听时机和on duration之间的相对时域位置以外，作为一种可能的实现方式，所述参考信号资源也可以部分或全部位于on duration的起始时刻之后。
S402、UE对接收到的参考信号进行测量。
在本发明实施中，UE对参考信号做测量的目的可以有多种，例如，用于信道质量的测量、用于波束管理的测量、用于时频跟踪的测量，或者用于移动性管理的测量等，本发明实施例不做具体限制。
作为一种可选的实施方式，在本发明实施例中，针对某些目的的测量，UE可以不向网络设备上报测量结果。例如当参考信号用于时频跟踪测量时，UE不需要上报测量结果。另外，针对波束管理的接收端波束选择，网络设备可以配置UE不上报，UE根据对参考信号的测量选择合适的接收波束即可。
而针对另一些目的的测量，UE可以向网络设备上报测量结果。
请参见图4B，在步骤S402之后，所述信号测量方法还可以包括：
S403、UE向网络设备上报测量结果，其中所述测量结果是基于对所述参考信号进行测量所得到的测量结果。
例如，针对信道质量的测量，UE可以上报CQI/PMI/RI/CRI/LI，网络设备可以根据UE上报的CSI获取准确的信道状态信息，选择合适的预编码、调制和编码方案，使CSI更匹配当前的信道(PDCCH/PDSCH)。再例如，针对波束管理中的发送端波束选择，UE可以上报测量的波束质量(例如L1-RSRP)和波束索引(resource indicator)，基站可以根据UE上报的波束质量和波束索引选择合适的发送波束。再例如，针对移动性管理，UE上报针对参考信号的测量结果，例如，参考信号接收功率(reference signal receiving power，RSRP)、参考信号接收质量(reference signal receiving quality，RSRQ)、信噪比(signal to interference plus noise ratio，SINR)等，用于基站判定是否执行小区切换(handover)过程。测量结果上报的时间可以是在non-active time内上报，也可以是在active time内上报，本发明实施例这里不做限制。例如：在on duration之前或者on duration内向网络侧上报测量结果；或者在确定WUS信号指示UE在WUS信号对应的on duration唤醒后，在WUS信号对应的on duration之前或者WUS信号对应的on duration内向网络侧上报测量结果；或者在UE连续睡眠M个DRX周期后的第1个DRX周期的on duration之前或者第1个DRX周期的on duration内向网络侧上报测量结果，等等。
接下来以针对CSI上报的测量为例，对UE上报测量结果(即上报CSI)的几种可能的方案进行详细介绍。
方式一、不管WUS的指示，网络设备配置UE在on duration之前的CSI上报资源上报。
A、CSI上报资源(或者简称为上报资源)的配置方式，包括但不限于以下五种(a.1、a.2、a.3、a.4、a.5)：
a.1、上报资源是已经配置好的周期性PUCCH资源。
一种可能的设计中，网络设备可以配置或指示周期性PUCCH资源编号。相应的，UE 根据网络设备的配置或者指示在所述周期性PUCCH资源编号所对应的PUCCH资源上发送CSI。
一种可能的设计中，网络设备可以配置UE在P个PUCCH资源上执行CSI上报，P大于或等于1。其中，当P大于1时，即P个PUCCH资源为多个PUCCH资源时，所述多个PUCCH资源具有相同的周期性PUCCH资源编号或者具有不同的周期性PUCCH资源编号，本发明实施例这里不做限制。
进一步的，所述P个PUCCH资源可以位于WUS监听时间之后，也可以位于WUS监听时间之前，这里不做限制。
当所述P个PUCCH资源位于WUS监听时间之后、on duration之前时，可选的，所述P个PUCCH资源与WUS监听时机的时间间隔大于设定阈值。可选的，所述P个PUCCH资源可以是on duration之前，且距离与on duration的起始时刻最近的P个PUCCH资源，例如，P＝1时，是on duration之前的且与on duration的起始时刻最近的PUCCH资源。可选的，所述P个PUCCH资源是WUS监听时机之后，且与WUS监听时机最近的PUCCH资源，例如，P＝1时，是WUS监听时机之后的且与WUS监听时机最近的第一个PUCCH资源。
当所述P个PUCCH资源位于WUS监听时间之前时，可选的，所述P个PUCCH是WUS监听时机之前，且与WUS监听时机最近的PUCCH，例如，P＝1时，是WUS监听时机之前的且与WUS监听时机最近的第一个PUCCH。可选的，网络设备在on duration之前配置一个上报窗，UE在上报窗内的PUCCH上执行CSI上报。所述上报窗的实现方法见如上配置用来确定参考信号资源的窗的方法。
a.2、上报资源是已经配置好的半持续PUCCH资源。
具体的，所述半持续PUCCH资源是被激活后的，尚未被去激活的PUCCH资源。半持续PUCCH资源的激活和去激活都是通过网络设备下发MAC CE信令来指示。其他具体确定PUCCH资源的方法与a.1类似，此处不再赘述。
a.3、上报资源是已经RRC配置的或DCI激活后的半持续PUSCH资源。
其中，针对DCI激活的半持续PUSCH资源，该半持续PUSCH资源尚未被去激活，即，UE尚未收到去激活DCI，或者尚未有其他原因造成该半持续PUSCH资源去激活。其他具体确定PUSCH资源的方法与a.1类似，此处不再赘述。
可选的，所述激活半持续PUSCH资源的DCI中的循环冗余校验(cyclic redundancy check,CRC)是由SP-CSI-RNTI加扰的，或CS-RNTI加扰的，本发明实施例这里不做限制。
所述RRC配置的半持续PUSCH资源是类型1(type1)的PUSCH资源，由RRC配置的上行调度授权(IE rrc-ConfiguredUplinkGrant)配置。
a.4、上报资源是网络设备新配置(或者说是额外配置)的PUCCH或PUSCH资源。
可选的，网络设备可以通过RRC信令配置所述PUCCH或PUSCH资源，包括PUCCH/PUSCH的时域和频域资源等。
可选的，该配置信令与配置WUS的信令是同一个。例如，位于PDCCH-WUS-Config IE。
可选的，该配置信令与配置C-DRX的信令是同一个。例如，位于DRX-Config IE。
网络设备可以在on duration前面配置1个或多个PUCCH资源，或者，配置1个或多个PUSCH资源。
可选的，网络设备配置PUCCH/PUSCH资源和on duration的起始时刻的时间偏移。
可选的，网络设备配置PUCCH/PUSCH资源和WUS监听时机的起始时刻或结束时刻之 间的时间偏移。
所述时间偏移可以是时隙偏移，或符号偏移，或子帧偏移。通过所述时间偏移可以确定新配置的PUCCH/PUSCH资源的时域位置。
a.5、不管WUS的指示，即，不管WUS指示UE唤醒还是不唤醒，也就是说，不管UE是否启动drx-onDurationTimer，UE都在on duration之前的新配置的PUCCH/PUSCH资源上报CSI。
可选的，所述配置的PUCCH或PUSCH资源位于WUS监听时间之后，on duration之前。
可选的，所述配置的PUCCH或PUSCH资源位于WUS监听时间之后，且，所述配置的PUCCH或PUSCH资源与WUS监听时机的时间间隔大于设定阈值x1。
可选的，所述配置的PUCCH或PUSCH资源位于WUS监听时间之后，且，所述配置的PUCCH或PUSCH资源与WUS监听时机的时间间隔小于设定阈值x2。
可选的，所述配置的PUCCH或PUSCH资源是在on duration之前，且与on duration的起始时刻之间的时间间隔小于设定阈值x3。
可选的，所述配置的PUCCH或PUSCH资源位于WUS监听时间之前。
可选的，所述配置的PUCCH或PUSCH资源位于WUS监听时间之前，且与WUS监听时机的时间间隔小于设定阈值x4。
B、CSI上报周期。
在本发明实施例中，CSI上报周期的含义为：如果一个on duration之前存在1个或多个所述上报资源(PUCCH/PUSCH)，定义一个时间段，所述时间段包括一个on duration之前的所述一个或多个PUCCH/PUSCH资源，则所述CSI上报周期等于相邻的两个所述时间段的起始时刻(或结束时刻)之间的时间间隔。
在本发明实施例中，CSI上报周期的具体实现方式，可以是以下几种方式中的至少一种：
b.1、DRX长周期的on duration之前和DRX短周期的on duration之前都存在所述CSI上报资源。这样，当UE进入DRX短周期，所述CSI上报周期变短。也可以理解成，所述CSI上报没有固定的周期。
一种可能的设计中，DRX长周期的on duration之前才存在所述CSI上报资源，DRX短周期的on duration之前不存在所述CSI上报资源。
可选的，如果DRX短周期的on duration和DRX长周期的on duration重叠，并且此时DRX短周期定时器(drx-shortCycleTimer)正在运行，表明UE当前处于DRX短周期，此时可以规定，这样的on duration之前也有所述CSI上报资源。这样，所述CSI上报资源有固定的周期，即时长等于1个DRX长周期的时长；
可选的，如果DRX短周期的on duration和DRX长周期的on duration重叠，并且此时DRX短周期定时器(drx-shortCycleTimer)正在运行，表明UE当前处于DRX短周期，此时可以规定，这样的on duration之前不存在所述CSI上报资源。这样，所述CSI上报资源可能没有固定的周期，会存在某些场景，两个相邻的所述CSI上报资源之间的时长大于1个DRX长周期的时长。
一种可能的设计中，只有存在WUS监听时机的DRX on duration之前才配置所述CSI上报资源。
可选的，如果并不是每个DRX长周期的on duration之前都存在WUS监听时机，则作为 一种可能的实现方式，只有存在WUS监听时机的DRX长周期的on duration之前才配置所述CSI上报资源。
一种可能的设计中，网络设备配置所述CSI上报周期为1个DRX长周期的N倍，或者为1个WUS监听周期的N倍，其中N为正整数。
C、CSI上报和CSI上报资源之间的关系。
可以理解的是，当UE在on duration之前的CSI上报资源上向网络设备上报CSI时，所述上报的CSI是基于对上述参考信号资源上的参考信号进行测量而得到的测量结果。应理解的是，上文中的所述参考信号资源在所述CSI上报资源之前。
一种可能的设计中，所述参考信号资源与所述CSI上报资源之间的时间间隔大于设定阈值。
一种可能的设计中，在所述参考信号资源中，至少存在R个CSI-RS资源(或者简称为CSI资源)与所述CSI上报资源之间的时间间隔大于设定阈值。R大于或等于1。例如，所述设定阈值大于或等于CSI处理和计算的时间。
一种可能的设计中，在一个on duration之前，既存在所述参考信号资源，也存在所述CSI上报资源。另一种可能的设计中，在一个on duration之前，只存在所述参考信号资源，不存在所述CSI上报资源。
方式二、WUS指示UE在on duration唤醒时，UE在该on duration之前的CSI上报资源上报CSI。
当然，UE可以在激活时间内正常上报，例如：在WUS指示UE唤醒的on duration内正常上报，而在WUS指示UE睡眠的on duration内可以不上报(既不在on duration之前上报，也不在on duration内上报)。
方式二中CSI上报资源的配置方式可以参考上述方式一中的配置方式，此处不再赘述。
方式三、UE在连续睡眠M个DRX周期之后，UE才在第M+1个DRX周期的on duration之前的CSI上报资源上报CSI。其中，M为大于或者等于0的整数。
也即，UE在连续睡眠M个DRX周期之后的第1个DRX周期的on duration之前的CSI上报资源上报CSI，而在UE睡眠的这M个DRX周期内，UE可以不上报CSI。
应理解，在第M+1个DRX周期，无论WUS指示UE唤醒还是不唤醒，UE都可以在第M+1个DRX周期的on duration之前上报CSI。
所述DRX周期为DRX长周期或者DRX短周期，这里不做限制。
一种可能设计中，当连续M个WUS监听时机集合都指示UE不需要唤醒时，UE在所述连续M个WUS监听时机集合指示UE不需要唤醒的DRX周期之后的第一个DRX周期的on duration之前的所述CSI上报资源上报CSI。其中，一个on duration之前的一个或多个WUS监听时机称为一个WUS监听时机集合。
方式三中CSI上报资源的配置方式可以参考上述方式一中的配置方式，此处不再赘述。
方式四、如果WUS指示在on duration内UE唤醒监听PDCCH，UE在on duration内的CSI上报资源执行CSI上报，网络配置或协议规定UE在on duration内所上报的CSI可以是基于on duration之前的所述参考信号资源执行测量后的测量结果。
如果WUS指示UE不唤醒，UE在on duration内不上报CSI。
可选的，网络配置UE在on duration内的前E个CSI上报资源所上报的CSI是基于on duration之前的所述参考信号资源执行测量后的测量结果。E大于或等于1。
可选的，网络配置或协议规定UE在on duration内的第一个CSI上报资源所上报的CSI是基于on duration之前的所述参考信号资源执行测量后的测量结果。
可选的，网络配置或协议规定UE在on duration内的特定时间段内的CSI上报资源所上报的CSI是基于on duration之前的所述参考信号资源执行测量后的测量结果。可选的，所述特定时间段为on duration开始的一个时间段。例如，所述特定时间段为on duration开始的前X个时隙，X大于或等于1。
作为一种可能的实现方式，所述CSI上报资源是已经配置好的周期性PUCCH资源。
作为一种可能的实现方式，所述CSI上报资源是已经激活后的，尚未被去激活的半持续性PUCCH资源。
作为一种可能的实现方式，所述CSI上报资源是已经激活后的，尚未被去激活的半持续性PUSCH资源。
可选的，所述半持续性PUSCH资源是DCI激活的，尚未被去激活的PUSCH资源。可选的，所述DCI的CRC是由CS-RNTI或SP-CSI-RNTI加扰的。
可选的，所述半持续性PUSCH资源是RRC信令配置的，尚未被释放的PUSCH资源。
可以理解的是，如果WUS指示在on duration内UE唤醒监听PDCCH，且在该on duration之前(且在上一个on duration之后)存在如上所述参考信号资源，则UE在on duration内所上报的CSI可以是基于on duration之前的所述参考信号资源执行测量后的测量结果。
另外，如上所述，为了减少UE接收所述参考信号资源上发送的所述参考信号的频率，以节省功耗，可能并不是每个on duration之前都存在所述参考信号资源(例如，当包含所述参考信号资源的第一时间段的周期是DRX周期的2倍时)。如果在该on duration之前(且在上一个on duration之后)不存在如上所述参考信号资源，并且WUS指示在on duration内UE唤醒监听PDCCH，则当在该on duration之前的最接近该on duration的所述第一时间段比在该on duration之前的上一次激活时间距离该on duration更近时，UE在on duration内所上报的CSI可以是基于该on duration之前的最接近该on duration的所述第一时间段内的所述参考信号资源执行测量后的测量结果，否则，当在该on duration之前的最接近该on duration的所述第一时间段比在该on duration之前的上一次激活时间距离该on duration更远时，UE在on duration内所上报的CSI可以是基于该on duration之前的上一次激活时间内的参考信号资源执行测量后的测量结果。
方式五、UE在连续睡眠M个DRX周期之后，无论WUS指示UE在第M+1个DRX周期是否唤醒，UE在第M+1个DRX周期的on duration内的CSI上报资源执行CSI上报。其中，网络配置或协议规定UE在第M+1个DRX周期的on duration内所上报的CSI可以是基于on duration之前的所述参考信号资源执行测量后的测量结果。
其中，在UE睡眠的所述M个DRX周期内，UE可以不上报CSI。
所述第M+1个DRX周期是UE连续睡眠M个DRX周期之后的第一个DRX周期，M为大于或等于0的整数。
方式五中CSI上报资源的配置方式可以参考上述方式四中CSI上报资源的配置方式，此处不再赘述。
需要说明的是，在方式四中的UE唤醒的DRX周期，和在方式五中的第M+1个DRX周期，如果WUS指示UE唤醒，则UE在on duration内，已经配置好的或已经激活的参考信号资源正常发送。所以，除了UE在on duration内的特定CSI上报资源所上报的CSI是基于on  duration之前的所述参考信号资源测量的，UE在之后的CSI上报资源所上报的CSI是基于on duration(或者说是active time)内的参考信号资源测量的。在方式五中的第M+1个DRX周期，如果WUS指示UE仍然不唤醒，则只有on duration之前才存在所述参考信号资源，所以，UE在on duration内所上报的CSI只能是基于on duration之前的所述参考信号资源执行测量后的测量结果。
所述特定CSI上报资源是被配置用来上报基于on duration之前的所述参考信号资源的测量结果的上报资源。
一种可能的设计中，网络设备可以配置当连续M个WUS监听时机集合都指示UE不需要唤醒时，UE在所述连续M个WUS监听时机集合指示UE不需要唤醒的DRX周期之后的第一个DRX周期的on duration内的CSI上报资源上报CSI。
可以理解的是，如果如上描述的参考信号资源和CSI上报资源是新配置的，而不是已经配置好的资源时，如果参考信号资源或CSI上报资源处于激活时间，例如DRX-inactivity timer正在运行，则参考信号资源不发送，UE也不在CSI上报资源上上报CSI。因为UE处于激活时间，UE可以对已经配置好的参考信号资源，或已经激活的参考信号资源执行测量，UE在已经配置好的周期性CSI上报资源，或已经激活的CSI上报资源上上报CSI。
上述方案中，UE可以在on duration之前(non-active time内)执行参考信号的测量，并且可以在non-active time或active time对on duration之前的测量结果进行上报，这样使得UE即便在长时间睡眠过程中或者长时间睡眠唤醒后，UE或者网络设备也可以及时得到准确的参考信号测量结果，进而保证PDCCH-WUS的可靠性、UE长时间睡眠唤醒后的性能，另外UE还可以基于non-active time内的参考信号进行波束管理，避免beam failure，节省UE功耗。
实施例二
参见图13A，为本发明实施例中的另一种信号测量方法的流程图，该方法包括：
S1301、在特定on duration内向UE发送参考信号，其中至少一个所述特定on duration位于DRX状态的non-active time内。
S1302、UE对接收到的参考信号进行测量。
具体的，UE在网络配置特定on duration内，不管WUS的指示(例如，即使WUS指示UE不唤醒，UE不开启DRX-on duration timer)，UE都假设参考信号一定发送，且UE可以接收参考信号执行参考信号测量和上报。也就是说，如果有一个特定on duration到来时，UE不开启DRX-on duration timer，则该特定on duration是位于DRX状态的non-active time内，那么UE就会在DRX状态的non-active time内接收参考信号并执行参考信号的测量。
进一步的，UE还可以在所述特定on duration内向网络侧上报测量结果。请参见图13B，上述步骤S1302之后还包括：S1303、UE在所述特定on duration内向网络设备上报测量结果，其中所述测量结果是基于对所述参考信号进行测量所得到的测量结果。
这样，当有特定on duration位于DRX状态的non-active time内时，UE就可以实现在DRX状态的non-active time上报测量结果。
除了特定on duration外的其它on duration，如果WUS指示UE不唤醒，则UE不启动DRX-on duration timer，在这样的on duration内，UE不假设参考信号一定发送，UE也不执行参考信号的测量和上报。可选的，网络设备在这样的on duration内不发送参考信号。
在本发明实施例中，所述特定on duration可以是周期性的，也可以是非周期性的，本发明实施例这里不做限制。例如，所述特定on duration按照设定的时间间隔周期性地出现，所述特定on duration的出现周期为DRX周期的P倍，其中P为正整数。例如，所述特定on duration为所述UE连续睡眠M个DRX周期后的第1个DRX周期的on duration。
需要说明的是，本实施例中，参考信号的类型、参考信号的用途或者UE执行信号测量的目的等，可以参考上述实施例一中相关部分的描述，此处不再赘述。
下面，介绍特定on duration的几种具体配置方式。
第1种、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。例如图14所示，N＝3。当N＝1时，意味着，网络设备配置，不管WUS的指示，在每个DRX长周期的on duration内，UE都假设参考信号一定发送，且UE可以上报CSI。
如果当前DRX短周期定时器(drx-ShortCycleTimer)正在运行，表示UE处于DRX短周期。作为一种可选的实施方式，如果WUS指示UE在DRX短周期不需要唤醒，则在不需要唤醒的DRX短周期的on duration内，UE也假设参考信号一定发送，且UE可以上报测量结果。
第2种、网络设备配置，所述特定on duration是UE连续睡眠M个DRX cycle之后的第一个on duration(即第M+1个DRX cycle)。
所述DRX周期可以为DRX长周期，即UE在连续睡眠M个DRX长周期后的的第一个on duration接收参考信号并执行参考信号的测量及上报。当然，所述DRX周期也可以为DRX短周期，即UE在连续睡眠M个DRX短周期后的的第一个on duration接收参考信号并执行参考信号的测量及上报，如图15所示。
第3种、网络设备配置，如果连续M个WUS监听时机集合都指示UE不唤醒，则UE在所述连续M个WUS监听时机集合指示UE不需要唤醒的DRX周期之后的第一个DRX周期的on duration为所述特定on duration。
其中，一个on duration之前的一个或多个WUS监听时机称为一个WUS监听时机集合。
可选的，如果UE配置了DRX短周期，且DRX短周期的on duration之前也配置了WUS监听时机，所述连续M个WUS监听时机集合不包括DRX短周期的on duration之前的WUS监听时机集合。
下面介绍特定on duration内的CSI-RS资源。
如果WUS指示UE在特定on duration内不唤醒，UE假设一定发送的参考信号资源是已经配置好的周期性参考信号资源。
作为一种可能的实现方式，所述参考信号资源是也可以是已经激活的，尚未被去激活的半持续CSI-RS资源。
作为一种可能的实现方式，所述参考信号资源还可以是额外配置的CSI-RS资源。
下面介绍特定on duration内的CSI上报资源。
如果WUS指示UE在特定on duration内不唤醒，UE用于上报CSI的CSI上报资源是已经 配置好的周期性PUCCH资源。
作为一种可能的实现方式，所述CSI上报资源也可以是已经激活后的，尚未被去激活的半持续性PUCCH资源。
作为一种可能的实现方式，所述CSI上报资源是已经激活后的，尚未被去激活的半持续性PUSCH资源。
可选的，所述半持续性PUSCH资源是DCI激活的，尚未被去激活的PUSCH资源。可选的，所述DCI的CRC是由CS-RNTI或SP-CSI-RNTI加扰的，这里不做限制。
可选的，所述半持续性PUSCH资源是RRC信令配置的，尚未被释放的PUSCH资源。
可选的，UE在所述半持续性PUSCH资源上也可以发送上行数据。
上述方案中，UE可以在特定on duration内执行参考信号的测量和上报，当至少一个特定on duration在non-active time内时，就可以实现UE在non-active time内执行参考信号的测量和上报。这样，即便在UE长时间睡眠过程中或者长时间睡眠唤醒后，网络设备或UE也可以及时得到准确的参考信号测量结果，进而保证PDCCH-WUS的可靠性、UE长时间睡眠唤醒后的性能，另外UE还可以基于non-active time内的参考信号进行波束管理，避免beam failure，节省UE功耗。
应理解，以上实施例一和实施例二中的各实施方式还可以相互结合以实现不同的技术效果。
应理解，如上描述的实施例还可以应用于载波聚合(carrier aggregation,CA)或双连接(dual connectivity,DC)。
具体背景为，在CA/DC场景，网络设备可以通过物理层信令动态地指示UE在不同载波上的监听PDCCH的行为，可以灵活的控制UE监听PDCCH的载波数量，这样，可以在数据量较小时，使用较少的载波数监听PDCCH，在数据量较大时，使用较多的载波数监听PDCCH，从而可以避免UE一直采用固定数量的载波数监听PDCCH，达到降低UE功耗的目的。当UE在一个载波上不需要监听PDCCH时，该载波仍然处于激活状态，UE仍然要执行一些测量和上报，例如，执行时频同步，CSI测量和CSI上报，和/或RRM测量等行为。当UE在一个载波处于激活状态，但不监听PDCCH时，UE在该载波的行为可以称为是休眠行为(dormancy behavior)。例如，在CA场景，UE被配置了两个小区，一个主小区(PCell)，一个辅小区(SCell)，UE在RRC连接态被配置了DRX机制。UE在主小区上根据PDCCH-WUS的指示决定是否在DRX持续时间唤醒监听PDCCH，网络设备可以动态指示UE在辅小区上是否进入休眠行为，或从休眠行为回到正常监听PDCCH的状态。
当UE在一个载波上进入休眠行为后，UE仍然执行一些信道测量和上报的行为的目的是：为了维持该小区处于激活状态，以及在有数据到来时可以快速回到正常监听PDCCH的状态。但是，UE可能并不需要频繁的进行测量和上报。比如，网络设备为了节省UE功耗，或者根据UE发送的请求信息，或者当网络设备感知到UE移动速度较低时(信道状态变化较慢)，网络设备可以配置在一个载波处于休眠行为的UE执行测量和测量上报的频率，从而达到进一步节省UE功耗的目的。
所以，本实施例所描述的实施例一和实施例二中的各实施方式都可以适用于该CA/DC场景中，用来配置参考信号资源的时域位置，或者配置UE接收参考信号的时间段，以及配置UE执行CSI上报/RRM测量上报的时频资源，或配置UE执行CSI上报/RRM测量上 报的时间段等。
具体例1，UE在第一SCell上处于休眠行为，网络设备配置UE在第一SCell上只在特定时间段内执行测量和上报。包括但不限于如下至少一种：时频跟踪，CSI测量和CSI上报，波束管理，RRM测量和上报。
一种可能的实现方式，所述特定时间段与on duration的部分或全部重叠，其周期为DRX周期的整数倍。
可选的，所述特定时间段为on duration，其周期为DRX周期的整数倍。(此例中的特定时间段与如上所述的特定on duration类似)。
可选的，所述特定时间段为on duration的开始的一段时间，比如开始的前X个时隙。
其他请参考如上实施例一和实施例二中的各实施方式，不再赘述。
基于相同的技术构思，本发明实施例还提供了一种通信装置，该通信装置例如为UE。该通信装置具有实现上述方法设计中的UE的功能。这些功能可以通过硬件实现，也可以通过硬件执行相应的软件实现。所述硬件或软件包括一个或多个与上述功能相对应的单元。
例如，请参见图16，通信装置1600包括：接收单元1601，可以用于在不连续接收DRX状态的不活跃时间non-active time内接收参考信号；处理单元1602，可以用于对所述参考信号进行测量。
在一种可能的设计中，所述接收单元1601具体用于：在DRX状态的持续时间on duration之前的第一时间段接收参考信号。
在一种可能的设计中，所述第一时间段按照设定的时间间隔周期性地出现，所述第一时间段的出现周期为DRX周期或WUS周期的N倍，其中N为正整数。
在一种可能的设计中，所述接收单元1601具体用于：在所述通信装置连续睡眠M个DRX周期后的第1个DRX周期的on duration之前的第一时间段接收参考信号，其中M为大于或者等于0的整数。
在一种可能的设计中，所述第一时间段位于：所述on duration之前、且位于所述on duration对应的唤醒信号WUS检测时间之后；或者，所述第一时间段位于：所述on duration对应的WUS检测时间之前。
