Description

一种通信方法以及通信装置

技术领域
本申请涉及通信技术领域，尤其涉及一种通信方法以及通信装置。
背景技术
在终端和基站的通信过程中，为了满足通信系统对终端移动性的要求，终端需要对服务小区以及邻小区进行无线资源管理(radio resource management,RRM)测量，以使终端在进入新的小区时能够及时的进行小区选择/重选/切换。
在第五代(5th generation，5G)通信系统的新无线接入技术(new radio access technology，NR)中，无线资源控制连接态(radio resource control connected,RRC_connected)的终端可能会被配置非连续接收(discontinuous reception,DRX),目的是为了使终端每隔一定的周期进入持续时间(on duration)去收发数据，而在其他时间可以进入睡眠状态，不去监听物理下行控制信道(physical downlink control channel,PDCCH)，从而节省终端能耗。
在NR中，出于进一步节省终端能耗的考虑，有望引入节能信号(power saving signal)这一新的概念。网络设备可以为处于DRX状态的终端配置节能信号，用于指示终端在接下来的一个或者多个DRX周期是否需要唤醒去监听PDCCH。由于节能信号可能指示整个DRX周期都进入睡眠状态，由此会造成终端的激活时间(active time)减少，如果按照现有的RRM测量机制，会造成RRM测量的机会减少，降低了RRM测量的准确度。
基于上述分析，在引入了节能信号这一概念的前提下，亟需提供一种新的RRM测量机制。

应理解，本申请实施例中的“协议”可以是指通信领域的标准协议，例如可以包括LTE协议、NR协议以及应用于未来的通信系统中的相关协议，本申请对此不做限定。
可以理解的，若终端设备在该第一时段之前为非激活状态，则终端设备可以唤醒进入激活状态对该CSI-RS进行测量。
可选地，终端设备在该第一时段对该CSI-RS进行RRM测量完成以后，终端设备可以进入非激活状态，从而节省终端设备的能耗。
本申请在第一DRX周期内设置第一时段，即使第一DRX周期被指示进入睡眠状态，网络设备也会在该第一时段内发送CSI-RS，终端设备也会假设在第一时段内存在CSI-RS，并且终端设备可以在该第一时段内对该CSI-RS进行RRM测量，从而能够保证给终端设备提供足够的RRM测量机会，保证RRM测量的准确性，避免由于引入节能信号这一概念而对终端移动性RRM测量造成影响。

在本实施例中，网络设备和终端设备可以分别通过第一节能信号的发送时机确定第一时段，并且网络设备在该第一时段发送CSI-RS，而终端设备可以在该第一时段对CSI-RS进行RRM测量。
本实施例根据第一节能信号的发送时机确定相关联的第一时段，网络设备可以在该第一时段内发送CSI-RS，并且终端设备可以在该第一时段内对该CSI-RS进行RRM测量，从而能够保证给终端设备提供足够的RRM测量机会，保证RRM测量的准确性，避免由于引入节能信号这一概念而对终端移动性RRM测量造成影响。

具体地，终端设备为了检测第一节能信号，可能要在时段#A处从睡眠状态唤醒，该CSI-RS所占用的时段应当尽量靠近时段#A，这样可以在终端设备检测完第一节能信号之后接着进行RRM测量，而不需要单独为了进行RRM测量而从睡眠状态唤醒。此外，设置CSI-RS所占用的时段尽量靠近时段#A，也可以减少终端设备维持唤醒的时间，从而可以节省终端设备的能耗。
可选地，CSI-RS所占用的时段与时段#A之间的偏移值可以是CSI-RS所占用的时段的第一个字符与时段#A的第一个字符或最后一个字符之间的偏移值，或者也可以是CSI-RS所占用的时段的最后一个字符与时段#A的第一个字符或最后一个字符之间的偏移值，本申请对此并不限定。
结合第三方面或第四方面，在某些实现方式中，第一时段的时长可以小于或者等于第二时长阈值。终端设备因为执行RRM测量而维持激活状态的时间可以被限制，从而能够节约终端设备的功耗。
可选地，第一时段的时长可以为DRX周期持续时间的长度。

本实施例能够根据指示信息确定是否在第一DRX周期内进行RRM测量，使得终端设备对CSI-RS的测量更加灵活，终端设备可以根据指示信息决策在当前的第一DRX是否进行RRM测量，例如，可以根据指示信息确定在第一DRX周期内不进行RRM测量，从而有利于节约终端设备的能耗。
可选地，第一指示信息用于指示网络设备在第一DRX周期内可能发送CSI-RS或者一定发送CSI-RS。
可选地，第二指示信息用于指示网络设备在第二DRX周期内可能发送CSI-RS或者一定发送CSI-RS。
结合第五方面，在某些实现方式中，当指示信息包括第一指示信息时，终端设备根据指示信息确定是否在第一DRX周期内进行RRM测量，包括：若第一指示信息指示所述网络设备在所述第一DRX周期一定发送CSI-RS，则终端设备在第一DRX周期内进行RRM测量。
具体地，第一指示信息指示在第一DRX周期一定发送CSI-RS，由于终端设备不确定在下一个DRX周期是否会一定存在CSI-RS，则终端设备可以在第一DRX周期内进行RRM测量。若第一指示信息指示网络设备在第一DRX周期可能发送CSI-RS，则终端设备在第一DRX周期内可以进行RRM测量，也可以不进行RRM测量。
结合第五方面，在某些实现方式中，当指示信息包括第二指示信息时，终端设备根据指示信息确定是否在第一DRX周期内进行RRM测量，包括：若第二指示信息指示网络设备在第二DRX周期一定发送CSI-RS，则终端设备不在第一DRX周期内进行RRM测量；若第二指示信息指示网络设备在第二DRX周期可能发送CSI-RS，则终端设备在第一DRX周期内进行RRM测量。
具体地，若第二指示信息指示网络设备在第二DRX周期一定发送CSI-RS，则必然可以在第二DRX周期进行RRM测量，此时终端设备可以不在第一DRX周期内进行RRM测量，从而能够节约功耗。若第二指示信息指示网络设备在第二DRX周期可能发送CSI-RS，终端设备不确定是否可以在第二DRX周期进行RRM测量，为了保证具有足够的测量样本，则终端设备在第一DRX周期内进行RRM测量。
结合第五方面，在某些实现方式中，该方法还包括：终端设备根据节能信号的接收情况，确定在第一DRX周期是否检测PDCCH；以及终端设备根据指示信息确定是否在所述第一DRX周期内进行RRM测量，包括：所述终端设备根据在第一DRX周期是否检测PDCCH和所述指示信息确定是否在所述第一DRX周期内进行RRM测量。
结合第五方面，在某些实现方式中，当指示信息包括第一指示信息时，终端设备根据在第一DRX周期是否检测PDCCH和指示信息确定是否在第一DRX周期内进行RRM测量，包括：若第一指示信息指示网络设备在第一DRX周期可能发送CSI-RS，且终端设备在第一DRX周期检测PDCCH，则终端设备在第一DRX周期内进行RRM测量；
若第一指示信息指示网络设备在第一DRX周期可能发送CSI-RS，且终端设备在所述第一DRX周期不检测PDCCH，则终端设备不在第一DRX周期内进行RRM测量。
具体地，当终端设备在第一DRX周期检测PDCCH，则终端设备必然要进入激活状态，此时，由于终端设备必然要进入激活状态，所以之前第一指示信息指示的网络设备在第一DRX周期可能发送CSI-RS变成确定发送CSI-RS，可以理解的是，当网络设备确定终端设备在第一DRX周期检测PDCCH时，则网络设备在第一DRX周期确定发送CSI-RS，此时可以不管第一指示信息的指示。所以，终端设备也可以在第一DRX周期内进行RRM测量。
而当终端设备在第一DRX周期不检测PDCCH，则终端设备不开启持续时间定时器，可能要进入非激活状态，此时网络设备在第一DRX周期仅仅是可能发送CSI-RS。例如，此时，当第一指示信息用1个比特表示，且该比特为0时表示可能发送CSI-RS，则网络 设备在第一DRX周期可以不发送CSI-RS，则终端设备不在第一DRX周期内进行RRM测量。另外，当该比特为1时表示网络设备在第一DRX周期一定发送CSI-RS，此时即使终端设备在第一DRX周期不检测PDCCH，终端设备也可以在第一DRX周期内进行RRM测量，当然，终端设备也可以不在第一DRX周期内进行RRM测量。
可以理解的是，若网络设备确定终端设备在第一DRX周期检测PDCCH，或者第一指示信息指示网络设备在第一DRX周期一定发送CSI-RS时，则网络设备在第一DRX周期确定发送CSI-RS。若网络设备确定终端设备在第一DRX周期不检测PDCCH，且第一指示信息指示网络设备在第一DRX周期可能发送CSI-RS时，则网络设备在第一DRX周期可以不发送CSI-RS。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
本申请实施例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 for mobile communications，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、LTE频分双工(frequency division duplex，FDD)系统、LTE时分双工(time division duplex，TDD)、通用移动通信系统(universal mobile telecommunication system，UMTS)、全球互联微波接入(worldwide interoperability for microwave access，WiMAX)通信系统、第五代(5th generation，5G)通信系统或未来的新无线接入技术。
为便于理解本申请实施例，首先结合图1详细说明适用于本申请实施例的通信系统。图1示出了适用于本申请实施例的适用的通信系统的示意图。如图1所示，该通信系统100可以包括至少一个网络设备，例如图1所示的网络设备110；该通信系统100还可以包括至少一个终端设备，例如图1所示的终端设备120。网络设备110与终端设备120可通过无线链路通信。各通信设备，如网络设备110或终端设备120，可以配置多个天线，该多个天线可以包括至少一个用于发送信号的发射天线和至少一个用于接收信号的接收天线。另外，各通信设备还附加地包括发射机链和接收机链，本领域普通技术人员可以理解，它们均可包括与信号发送和接收相关的多个部件(例如处理器、调制器、复用器、解调器、解复用器或天线等)。因此，网络设备110与终端设备120可通过多天线技术通信。
应理解，该无线通信系统中的网络设备可以是任意一种具有无线收发功能的设备。该设备包括但不限于：演进型节点B(evolved NodeB，eNB或eNodeB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(例如，home evolved NodeB，或home Node B，HNB)、基带单元(base band unit，BBU)，无线保真(wireless fidelity，WIFI)系统中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission point，TP)或者发送接收点(transmission and reception point，TRP)等，还可以为5G，如，NR，系统中的gNB，或，传输点(TRP或TP)，5G系统中的基站的一个或一组(包括多个天线面板)天线面板，或者，还可以为构成gNB或传输点的网络节点，如基带单元(BBU)，或，分布式单元(distributed unit，DU)等。

为便于理解本申请实施例，首先对本申请中涉及到的相关技术内容作简单说明。
一、无线资源管理测量
无线资源管理(radio resource management,RRM)测量是终端对周期性的信号进行通信质量的测量，例如，测量的内容可以包括接收信号功率(reference signal receiving power，RSRP)，接收信号质量(reference signal receiving quality，RSRQ)或信干噪比(signal to interference plus noise，SINR)中的至少一项。
RRM测量的目的是为了使处于无线资源控制空闲态(radio resource control idle,RRC_idle)和无线资源控制非激活态(radio resource control inactive,RRC_inactive)的终端做小区选择/重选(cell selection/reselection)，以及为了使处于RRC连接态的终端做小区切换。由于RRM测量是为了满足通信系统对终端移动性的要求，以使终端在进入新的小区时能够及时的进行小区选择/重选/切换，所以RRM测量都是周期进行的。
目前用作RRM测量的参考信号主要有两种：同步信号/物理广播信道资源块(synchronization signal/physical broadcast channel block,SSB，具体为SSB中的辅同步信号(secondary synchronization signal))和信道状态信息参考信号(channel state information reference signal，CSI-RS)。SSB是小区级的信号，因此终端在RRC空闲态/非激活态/连接态都可以使用。而当前，CSI-RS只能由处于RRC连接态的终端使用，当终端处于RRC连接态时，基站会通过RRC信令配置一定的CSI-RS资源用作移动性RRM测量。在RRC连接态时，具体采用哪种信号做RRM测量(可以同时基于两种信号)，是由RRC信令进行配置的。本申请实施例主要针对RRC连接态，并且主要针对基于CSI-RS的RRM测量。
二、非连续接收
一般而言，基于包的数据流通常是突发性的，在一段时间内有数据传输，但在接下来的一段较长时间内没有数据传输。因此NR中可以为终端设备配置非连续接收(discontinuous reception，DRX)处理流程，在没有数据传输的时候，可以通过使终端设备停止检测PDCCH并停止接收相应数据传输来降低功耗，从而提升电池使用时间。
网络设备可以为处于RRC连接态的终端设备配置DRX周期(DRX cycle)，图2为DRX周期的示意图。DRX周期中包含一个“持续时间”(“On duration”)的时间区域，在该持续时间内，终端设备可以检测PDCCH，在该持续时间之后，为“非持续时间”(Opportunity for DRX)，持续时间和非持续时间共同构成了一个完整的DRX周期。
终端设备在每一个DRX周期时间起始位置(即持续时间的起始位置)开启一个定时器，该定时器的时间长度即为持续时间的时间长度，该定时器可以称之为持续时间定时器(drx-on duration timer)，终端设备在可以在该定时器的时间范围内检测PDCCH。如果终端设备在该持续时间定时器的时间范围内没有检测到PDCCH，那么定时器到期后终端设备进入睡眠状态，即终端设备在DRX周期的其余时间段内可以停止检测PDCCH，从而可以关闭接收电路，从而降低终端的功耗。如果终端设备在持续时间定时器的时间范围内检测到了PDCCH指示新的数据传输，那么终端设备就会开启DRX机制中的非激活定时器(drx-inactivity timer)，若终端设备在非激活定时器的运行时间内，继续检测到了PDCCH指示新的数据传输，则终端设备会重置(restart)该非激活定时器重新开始计数。如果非激活定时器正在运行，即使本来配置的持续时间定时器超时(即on duration时间结束)，终端设备依然需要继续检测PDCCH，直到非激活定时器超时。
在DRX机制中，还有其它一些定时器，例如DRX下行重传定时器(drx-retransmission timer DL)、DRX上行重传定时器(drx-retransmission timer UL)等，本申请的技术方案对该两种定时器不再进行具体描述。
当配置DRX时，终端的状态可以分为DRX激活(DRX active)态和DRX非激活(DRX non-active)态，UE处于DRX激活态的时间称为激活时间(active time)。如果上述定时器中(包括持续时间定时器、非激活定时器以及下行/上行重传定时器等)的任意一个正在运行，那么终端设备就会处于激活时间(即终端处于激活态)。在DRX机制中，如果终端设备处于激活时间，那么终端设备就需要检测PDCCH。应理解，还有其它一些情况会让终端设备处于激活时间，但本申请实施例并未过多涉及，故这里不再描述。
三、节能信号
NR中，出于进一步节省终端能耗的考虑，有望引入节能信号(power saving signal)这一新的概念。网络设备可以为处于DRX状态的终端配置节能信号，一般认为该节能信号发送在DRX周期之前，用于指示终端在接下来的一个或者多个DRX周期是否需要唤醒去监听PDCCH。该节能信号可以基于PDCCH信道，根据不同的功能可以将节能信号分为唤醒信号(wake-up signal,WUS)和/或睡眠信号(go to sleep signal，GTS)。以下是节能信号的三种配置方式：
(1)节能信号为唤醒信号，终端可以通过是否检测到该唤醒信号决定是否唤醒从而进入DRX周期的持续时间去检测PDCCH。图3是唤醒信号对处于DRX状态的终端进行指示的示意图。
如图3所示，终端在第一个DRX周期之前检测到唤醒信号，则终端可以开启持续时间定时器进入持续时间去检测PDCCH。进一步的，若终端检测到PDCCH指示新的数据传输，则可以开启非激活定时器。而在第一个DRX周期内，并且在第二个DRX周期之前，在预设的时域位置上并未检测到唤醒信号，则终端不需要在第二个DRX周期检测PDCCH，从而终端设备可以不开启持续时间定时器进入睡眠状态节省终端的功耗。
(2)节能信号为睡眠信号，终端可以通过是否检测到该睡眠信号决定是否唤醒从而进行DRX周期的持续时间去检测PDCCH。具体地，若终端设备检测到该睡眠信号，终端设备则不开启持续时间定时器从而进入睡眠状态，若终端设备未检测到该睡眠信号，则开启持续时间定时器进入持续时间去检测PDCCH。
(3)节能信号同时为唤醒信号和睡眠信号。例如，可以通过下行控制信息(downlink control information,DCI)中的一个比特指示终端唤醒进入持续时间去检测PDCCH或者指示终端不唤醒进入睡眠状态。
应理解，上述对无线资源管理测量、非连续接收、节能信号等的介绍是为了便于理解本申请的实施例，而不对本申请构成任何限定。在前述介绍的基础上，下面介绍现有技术中终端被配置非连续接收的情况下终端和基站之间进行RRM测量的机制。
现有技术中，如果一个终端被配置了DRX，并且使用的DRX周期大于80ms，那么终端只会期待在DRX周期的激活时间才会收到用作移动性RRM测量的CSI-RS，意味着在DRX的激活时间，基站必须要发送用作RRM测量的CSI-RS，而在DRX周期的睡眠时间，终端不期待CSI-RS的存在(终端不会唤醒去接收CSI-RS)，所以基站可以选择发送或者不发送用作RRM测量的CSI-RS。
而当DRX周期小于或等于80ms时，不管终端处于DRX激活时间还是DRX睡眠时间，基站都要发送用作RRM测量的CSI-RS，而终端也会认为该CSI-RS一直存在，因此终端可以基于CSI-RS进行RRM测量。
随着节能信号概念的引入，如果节能信号指示DRX周期进入睡眠状态(或不检测PDCCH)，终端将不会开启持续时间定时器，该周期就没有进入到激活时间，由此造成终端的激活时间减少(在引入节能信号之前，激活时间至少包括每个周期的持续时间)。如果按照现有的RRM测量机制，由于终端的激活时间减少，会造成RRM测量的机会减少，甚至整个RRM测量周期终端都得不到测量，进而造成终端做RRM测量的层1滤波(Layer1filtering)样本数减少，降低了RRM测量的准确度，对移动性影响较大。
基于上述分析，在引入了节能信号这一概念的前提下，亟需提供一种新的RRM测量机制。
本申请提供一种通信方法200，能够保证给终端提供足够的RRM测量机会，避免由于引入节能信号这一概念而对终端移动性RRM测量造成影响。下面结合图4进行介绍。
图4是本申请实施例的通信方法200的示意性流程图。图4所示的方法200包括步骤210至步骤240。
在步骤210中，网络设备确定终端设备在第一DRX周期内是否检测PDCCH。
在步骤220中，终端设备根据第一节能信号的接收情况，确定在第一DRX周期内是否检测PDCCH。
在步骤230中，网络设备在第一DRX周期内的第一时段向终端设备发送CSI-RS，该CSI-RS用于终端设备进行RRM测量。
相应地，在步骤230中，终端设备在第一DRX周期内的第一时段对网络设备发送的CSI-RS进行RRM测量。
具体地，网络设备可以先确定终端设备在第一DRX周期内是否检测PDCCH，或者说，网络设备可以先确定在第一DRX周期终端设备进入激活状态还是非激活状态，并且可以通过第一节能信号的发送情况对终端设备进行相应的指示，终端设备可以根据第一节能信号的接收情况，确定在第一DRX周期内是否检测PDCCH。
例如，可以预先配置在第一DRX周期之前的时段#A(例如，至少一个符号(symbol)或至少一个时隙(slot))来传输该第一节能信号，终端设备可以根据在该时段#A对第一 节能信号的接收情况来确定在第一DRX周期内是否检测PDCCH。
参见前文对节能信号的描述，终端设备根据第一节能信号的接收情况，确定在第一DRX周期内是否检测PDCCH，可以包括如下三种情况：
情况a：该第一节能信号为唤醒信号WUS，可以在时段#A检测该唤醒信号WUS，并且通过是否检测到该唤醒信号WUS来确定终端设备在第一DRX周期是否检测PDCCH。例如，若终端设备在时段#A检测到该唤醒信号WUS，则终端设备可以在第一DRX周期开启持续时间定时器进入持续时间去检测PDCCH。再例如，若终端设备在时段#A未检测到该唤醒信号WUS，则终端设备可以不开启持续时间定时器，不去检测PDCCH，终端设备在第一DRX周期进入非激活状态。
情况b：该第一节能信号为睡眠信号GTS，可以在时段#A检测该睡眠信号GTS，并且通过是否检测到该睡眠信号GTS来确定终端设备在第一DRX周期是否检测PDCCH。例如，若终端设备在时段#A未检测到睡眠信号GTS，则终端设备可以在第一DRX周期开启持续时间定时器进入持续时间去检测PDCCH。再例如，若终端设备在时段#A检测到该睡眠信号GTS，则终端设备可以不开启持续时间定时器，不去检测PDCCH，终端设备在第一DRX周期进入非激活状态。
情况c：该第一节能信号同时为唤醒信号WUS和睡眠信号GTS，终端设备可以在时段#A接收该第一节能信号，并且读取该第一节能信号的内容，根据该内容确定终端设备在第一DRX周期是否检测PDCCH。
例如，系统或者协议可以规定，或者网络设备可以和终端设备进行约定，可以用一个比特的“0”指示终端设备不检测PDCCH，可以用一个比特的“1”指示终端设备检测PDCCH，当第一节能信号的内容为一个比特的“0”时，则终端设备可以确定在第一DRX周期不检测PDCCH，当第一节能信号的内容为一个比特的“1”时，则终端设备可以确定在第一DRX周期检测PDCCH。
在本实施例中，第一DRX周期内包括第一时段，在该第一时段内，网络设备可以向终端设备发送用作RRM测量的至少一个CSI-RS，而终端设备在该第一时段内可以对该CSI-RS进行测量。
该第一时段可以为系统或者协议规定，也可以由网络设备和终端设备之间进行约定。例如，网络设备可以通过半静态信令或者动态信令对终端设备进行配置。其中，半静态信令例如可以是RRC信令。动态信令例如可以是MAC控制元素(MAC control element,MAC CE)或者DCI。
应理解，本申请实施例中的“协议”可以是指通信领域的标准协议，例如可以包括LTE协议、NR协议以及应用于未来的通信系统中的相关协议，本申请对此不做限定。
可以理解的，若终端设备在该第一时段之前为非激活状态，则终端设备可以唤醒进入激活状态对该CSI-RS进行测量。
可选地，终端设备在该第一时段对该CSI-RS进行RRM测量完成以后，终端设备可以进入非激活状态，从而节省终端设备的能耗。
可选地，网络设备可以在第一DRX周期内第一时段之外的时间发送CSI-RS。
可选地，网络设备在第一DRX周期内第一时段之外的时间不发送CSI-RS，从而节省网络设备的能耗。
可选地，网络设备可以在该第一时段内按照网络设备配置好的发送周期发送CSI-RS。
可选地，该第一DRX周期可以是第一节能信号所指示的一个或者多个DRX周期中的任意一个，例如，第一个或者最后一个，本申请对此并不限定。
在本实施例中，该第一时段可以为第一DRX周期内的任意时段，该第一时段的长度可以为小于或者等于第一DRX周期的长度并且大于或者等于至少一个CSI-RS所占用的时段的任意长度。
例如，该第一时段包括所述第一DRX周期的持续时间的部分或者全部。
再例如，该第一时段包括所述第一DRX周期的非持续时间的部分或者全部。
再例如，该第一时段可以为第一DRX周期内的持续时间。
再例如，该第一时段的长度可以等于第一DRX周期内的持续时间的长度。
再例如，该第一时段的长度可以等于第一DRX周期的长度。
再例如，当第一DRX周期进入激活状态时，该第一时段的长度可以等于激活时间的长度。
下面将结合附图，对本申请实施例第一时段的可能设置方式进行介绍。
方式1
图5示出了第一时段的设置方式的一例的示意图。在图5中，网络设备可以通过时段#A将第一节能信号发送给终端设备，该第一节能信号可以用于指示终端设备在第一DRX周期不检测PDCCH(左图)还是检测PDCCH(右图)。在方式1中，无论根据第一节能信号的收发情况确定终端设备在第一DRX周期不检测PDCCH还是检测PDCCH，该第一时段均为DRX周期内的持续时间。也就是说，该第一时段的起始位置和结束位置和持续时间完全相同，或者说，该第一时段和持续时间完全重合。
方式2
图6示出了第一时段的设置方式的另一例的示意图。在图6中，如果根据第一节能信号的收发情况确定终端设备在第一DRX周期不检测PDCCH(左图)，该第一时段为DRX周期内的持续时间。
如果根据第一节能信号的收发情况确定终端设备在第一DRX周期检测PDCCH(右图)，该第一时段为DRX周期内的激活时间。容易理解的，当终端设备在第一DRX周期进入激活状态时，在第一DRX周期内的激活时间至少包括持续时间，如果在该持续时间内检测到PDCCH指示新的数据传输，该激活时间还应当包括非激活定时器运行的时间。
方式3
图7示出了第一时段的设置方式的再一例的示意图。在图7中，当第一DRX周期的长度小于某一时长阈值时，无论根据第一节能信号的接收情况确定终端设备在第一DRX周期不检测PDCCH(左图)还是检测PDCCH(右图)，该第一时段均为整个DRX周期。也就是说，该第一时段的起始位置和结束位置和一个DRX周期完全相同，或者说，该第一时段和一个DRX周期完全重合。
该时长阈值可以由系统或者协议规定，也可以由网络设备和终端设备之间进行约定。例如，该时长阈值为80毫秒(ms)。
在步骤240中，终端设备向网络设备发送RRM测量结果。
相应地，在步骤240中，网络设备接收终端设备发送的RRM测量结果。
具体地，终端设备在对CSI-RS测量完成以后，可以将RRM测量结果及时上报给网络设备，从而，网络设备可以根据该测量结果进行终端设备的小区选择/重选/切换等操作。
本申请实施例在第一DRX周期内设置第一时段，即使第一DRX周期被指示进入睡眠状态，网络设备也会在该第一时段内发送CSI-RS，终端设备也会假设在第一时段内存在CSI-RS，并且终端设备可以在该第一时段内对该CSI-RS进行RRM测量，从而能够保证给终端设备提供足够的RRM测量机会，保证RRM测量的准确性，避免由于引入节能信号这一概念而对终端移动性RRM测量造成影响。
本申请还提供一种通信方法300，也能够保证给终端提供足够的RRM测量机会，避免由于引入节能信号这一概念而对终端移动性RRM测量造成影响。下面结合图8进行介绍。
图8是本申请实施例的通信方法300的示意性流程图。图8所示的方法300包括步骤310至步骤340。
在步骤310中，网络设备根据第一节能信号的发送时机确定第一时段。
在步骤320中，终端设备根据第一节能信号的接收时机确定该第一时段。
在步骤330中，网络设备在第一时段向终端设备发送CSI-RS，该CSI-RS用于终端设备进行RRM测量。
相应地，在步骤330中，终端设备在第一时段对网络设备发送的CSI-RS进行RRM测量。
参见前文的相关描述，网络设备可以预先配置时段#A来传输第一节能信号(该时段#A也可以被称为被第一节能信号占用的时段)，终端设备可以根据在该时段#A对第一节能信号的接收情况来确定在时段#A之后的至少一个DRX周期内是否检测PDCCH。
区别于前述实施例，在本实施例中，网络设备和终端设备可以分别通过第一节能信号的发送时机确定第一时段，并且网络设备在该第一时段发送CSI-RS，而终端设备可以在该第一时段对CSI-RS进行RRM测量。
在本实施例中，根据第一节能信号的发送时机确定第一时段，可以包括如下两种方式：
方式A
在配置第一节能信号时，可以配置与第一节能信号相关联的CSI-RS。
具体地，在配置第一节能信号的传输时域位置(即时段#A)时，可以一起配置该CSI-RS的传输时域位置(即该CSI-RS所占用的时段)，并且根据该CSI-RS所占用的时段确定第一时段，容易理解的，该第一时段应当包括该CSI-RS所占用的时段。
可选地，该第一时段的长度可以大于CSI-RS所占用的时段。
可选地，该第一时段的长度也可以等于CSI-RS所占用的时段，此时该第一时段即为CSI-RS所占用的时段。
在每个周期，该时段#A和该CSI-RS所占用的时段的相对位置是固定的，终端设备和网络设备根据相关配置信息以及该时段#A的时域位置，能够确定该第一时段的具体位置，并且在该第一时段上发送/测量该CSI-RS。例如，网络确定CSI-RS所占用的时段的方法为配置与时段#A之间的偏移值。
由于第一节能信号所占用的时段#A通常都是周期性配置的，因此配置的CSI-RS也是周期性的，网络设备可以周期性在该第一时段发送CSI-RS，而终端设备可以在该第一时 段周期性的进行RRM测量。
图9示出了第一时段的设置方式的再一例的示意图。如图9所示，CSI-RS所占用的时段与时段#A之间的偏移值为offset1。可选地，协议可以规定offset1小于或者等于第一时长阈值。
具体地，终端设备为了检测第一节能信号，可能要在时段#A处从睡眠状态唤醒，该CSI-RS所占用的时段应当尽量靠近时段#A，这样可以在终端设备检测完第一节能信号之后接着进行RRM测量，而不需要单独为了进行RRM测量而从睡眠状态唤醒。此外，设置CSI-RS所占用的时段尽量靠近时段#A，也可以减少终端设备维持唤醒的时间，从而可以节省终端设备的能耗。
可选的，协议可以规定offset1小于或者等于第一时长阈值。当协议规定了第一时长阈值时，则基站需要确保与时段#A关联配置的CSI-RS所占用的时段与时段#A之间的偏移值offset1小于或等于第一时长阈值。如果协议没有规定offset1小于或者等于第一时长阈值，则依赖于基站实现将配置的CSI-RS所占用的时段尽量靠近时段#A。
可选地，CSI-RS所占用的时段与时段#A之间的偏移值offset1可以是CSI-RS所占用的时段的第一个字符与时段#A的第一个字符或最后一个字符之间的偏移值，或者也可以是CSI-RS所占用的时段的最后一个字符与时段#A的第一个字符或最后一个字符之间的偏移值，本申请对此并不限定。
可选地，在图9中，与前述实施例不同的是，该第一时段可以位于第一DRX周期的持续时间内，或者也可以位于第一DRX周期之外。
方式B
在配置第一节能信号时，可以直接配置与第一节能信号相关联的第一时段。
第一时段与第一节能信号所占用的时段#A相关联，网络设备和终端设备可以分别通过第一节能信号的发送时机确定该第一时段，网络设备在该第一时段发送CSI-RS，而终端设备可以在该第一时段对CSI-RS进行RRM测量。
具体地，可以由协议或者系统规定，或者通过网络设备的配置，本实施例的第一时段和第一节能信号所占用的时段#A相互关联，终端设备和网络设备根据该时段#A的时域位置能够确定第一时段的时域位置，之后在该第一时段发送/测量该CSI-RS。
该第一时段可以由网络通过信令配置，也可以由协议或者系统规定。该第一时段的单位可以是：符号(symbol)、时隙(slot)、子帧(subframe)、帧(frame)、微秒、毫秒(ms)、秒中任意一种。
例如，当第一时段由网络配置时，可以通过RRC信令或MAC CE信令进行配置，作为示例，网络设备在配置第一节能信号时配置该第一时段的长度t＝10ms。
再例如，第一时段可以由系统默认规定，作为示例，对于DRX周期大于80ms，第一时段的长度t＝10ms，对于DRX周期小于或者等于80ms，第一时段的长度t＝15ms。
可选地，第一时段的时长可以小于或者等于第二时长阈值。终端设备因为执行测量而维持激活状态的时间可以被限制，从而能够节约终端设备的功耗。
可选地，第一时段的时长可以为DRX周期持续时间的长度。
图10示出了第一时段设置方式的再一例的示意图。
在图10中，第一时段的长度可以等于第一DRX周期的持续时间的长度。
基于类似的理解，为了使终端设备在检测完第一节能信号之后紧接着进行RRM测量，以及为了减少终端设备的唤醒时间，该第一时段可以靠近时段#A设置。
例如，在图10中，第一时段可以从时段#A的第一个符号或者最后一个符号开始。
在方式B中CSI-RS的配置方式和方式A中CSI-RS的配置方式不同。具体地，基站可以不考虑第一节能信号是如何配置的，而单独配置周期性的CSI-RS，只需要保证在第一时段内刚好会出现CSI-RS供终端设备做RRM测量即可。
在步骤340中，终端设备向网络设备发送RRM测量结果。
相应地，在步骤340中，网络设备接收终端设备发送的RRM测量结果。
具体地，终端设备在对CSI-RS测量完成以后，可以将RRM测量结果及时上报给网络设备，从而，网络设备可以根据该测量结果进行终端设备的小区选择/重选/切换等操作。
本申请实施例通过根据第一节能信号的发送时机确定相关联的第一时段，网络设备在该第一时段内发送CSI-RS，并且终端设备可以在该第一时段内对该CSI-RS进行RRM测量，从而能够保证给终端设备提供足够的RRM测量机会，保证RRM测量的准确性，避免由于引入节能信号这一概念而对终端移动性RRM测量造成影响。
本申请还提供一种通信方法400，能够提供给网络设备和终端设备在DRX周期内不发送/测量CSI-RS的可能性，从而有助于节省终端设备和网络设备的功耗。
图11是本申请实施例的通信方法400的示意性流程图。图11所示的方法400包括步骤410至步骤420。
在步骤410中，终端设备接收网络设备发送的指示信息，该指示信息包括第一指示信息和/或第二指示信息，第一指示信息用于指示网络设备在第一DRX周期内发送CSI-RS的可能性，第二指示信息用于指示网络设备在第二DRX周期内发送CSI-RS的可能性，第二DRX周期是位于第一DRX周期之后的DRX周期。
在步骤420中，终端设备根据指示信息确定是否在第一DRX周期内进行RRM测量。
具体地，第一指示信息用于指示网络设备在第一DRX周期内发送CSI-RS的可能性，例如，可以包括指示网络设备在第一DRX周期内一定发送CSI-RS或者可能发送CSI-RS。作为示例，可以通过DCI域中的一个或者多个比特，或者通过不同的解调参考信号(demodulation reference signal,DMRS)扰码序列来指示网络设备在第一DRX周期内一定发送CSI-RS或者可能发送CSI-RS。
类似的，第二指示信息用于指示网络设备在第二DRX周期内发送CSI-RS的可能性，例如，可以包括指示网络设备在第二DRX周期内一定发送CSI-RS或者可能发送CSI-RS。作为示例，可以通过DCI域中的一个或者多个比特，或者通过不同的DMRS扰码序列来指示网络设备在第二DRX周期内一定发送CSI-RS或者可能发送CSI-RS。
终端设备可以根据指示信息确定是否在第一DRX周期内进行RRM测量，也就是说，终端设备可以根据第一DRX周期内CSI-RS的发送可能性和/或第二DRX周期内CSI-RS的发送可能性确定是否在当前的第一DRX周期进行RRM测量。
可选地，当确定要在第一DRX周期内进行RRM测量时，参见前述实施例的表述，可以在前述实施例中介绍的第一时段内进行RRM测量，本申请在此不再赘述。
本申请实施例能够根据指示信息确定是否在第一DRX周期内进行RRM测量，使得终端设备对CSI-RS的测量更加灵活，终端设备可以根据指示信息决策在当前的第一DRX 是否进行RRM测量，例如，可以根据指示信息确定在第一DRX周期内不进行RRM测量，从而有利于节约终端设备的能耗。
下面根据指示信息所包括的内容的不同，分情况进行阐述步骤420中终端设备如何根据指示信息确定是否在第一DRX周期内进行RRM测量。
情况1
当指示信息包括第一指示信息时，在步骤420中，终端设备根据指示信息确定是否在所述第一DRX周期内进行RRM测量，包括：
若第一指示信息指示网络设备在第一DRX周期一定发送CSI-RS，则终端设备在第一DRX周期内进行RRM测量。
具体地，第一指示信息指示在第一DRX周期一定发送CSI-RS，由于终端设备不确定在下一个DRX周期是否会一定存在CSI-RS，则终端设备可以在第一DRX周期内进行RRM测量。
若第一指示信息指示网络设备在第一DRX周期可能发送CSI-RS，则终端设备在第一DRX周期内可以进行RRM测量，也可以不进行RRM测量。
情况2
当指示信息包括第二指示信息时，在步骤420中，终端设备根据指示信息确定是否在所述第一DRX周期内进行RRM测量，包括：
若第二指示信息指示网络设备在第二DRX周期一定发送CSI-RS，则终端设备不在第一DRX周期内进行RRM测量；
若第二指示信息指示网络设备在第二DRX周期可能发送CSI-RS，则终端设备在第一DRX周期内进行RRM测量。
容易理解的，若第二指示信息指示网络设备在第二DRX周期一定发送CSI-RS，则必然可以在第二DRX周期进行RRM测量，此时终端设备可以不在第一DRX周期内进行RRM测量，从而能够节约功耗。
若第二指示信息指示网络设备在第二DRX周期可能发送CSI-RS，终端设备不确定是否可以在第二DRX周期进行RRM测量，为了保证具有足够的测量样本，则终端设备在第一DRX周期内进行RRM测量。
可选地，方法400还包括：
终端设备根据节能信号的接收情况，确定在第一DRX周期是否检测PDCCH；
在步骤420中，终端设备根据指示信息确定是否在第一DRX周期内进行RRM测量，包括：
终端设备根据在第一DRX周期是否检测PDCCH和指示信息确定是否在第一DRX周期内进行RRM测量。
可以根据节能信号的接收情况，确定在第一DRX周期是否检测PDCCH，终端设备根据在第一DRX周期是否检测PDCCH和指示信息确定是否在第一DRX周期内进行RRM测量，具体地，根据指示信息所包括的内容的不同，可以分成以下几种情况：
情况3
当指示信息包括第一指示信息时，终端设备根据在第一DRX周期是否检测PDCCH和指示信息确定是否在所述第一DRX周期内进行RRM测量，包括：
若第一指示信息指示网络设备在所述第一DRX周期可能发送CSI-RS，且终端设备在第一DRX周期检测PDCCH，则终端设备在所述第一DRX周期内进行RRM测量；
若第一指示信息指示网络设备在第一DRX周期可能发送CSI-RS，且终端设备在第一DRX周期不检测PDCCH，则终端设备不在第一DRX周期内进行RRM测量。
具体地，当终端设备在第一DRX周期检测PDCCH，则终端设备必然要进入激活状态，此时，由于终端设备必然要进入激活状态，所以之前第一指示信息指示的网络设备在第一DRX周期可能发送CSI-RS变成确定发送CSI-RS，可以理解的是，当网络设备确定终端设备在第一DRX周期检测PDCCH时，则网络设备在第一DRX周期确定发送CSI-RS，此时可以不管第一指示信息的指示。所以，终端设备也可以在第一DRX周期内进行RRM测量。
而当终端设备在第一DRX周期不检测PDCCH，则终端设备不开启持续时间定时器，可能要进入非激活状态，此时网络设备在第一DRX周期仅仅是可能发送CSI-RS。例如，此时，当第一指示信息用1个比特表示，且该比特为0时表示可能发送CSI-RS，则网络设备在第一DRX周期可以不发送CSI-RS，则终端设备不在第一DRX周期内进行RRM测量，另外，当该比特为1时表示网络设备在第一DRX周期一定发送CSI-RS，此时即使终端设备在第一DRX周期不检测PDCCH，终端设备也可以在第一DRX周期内进行RRM测量，当然，终端设备也可以不在第一DRX周期内进行RRM测量。
可以理解的是，若网络设备确定终端设备在第一DRX周期检测PDCCH，或者第一指示信息指示网络设备在第一DRX周期一定发送CSI-RS时，则网络设备在第一DRX周期确定发送CSI-RS。若网络设备确定终端设备在第一DRX周期不检测PDCCH，且第一指示信息指示网络设备在第一DRX周期可能发送CSI-RS时，则网络设备在第一DRX周期可以不发送CSI-RS。
情况4
当指示信息包括第二指示信息时，终端设备根据在第一DRX周期是否检测PDCCH和指示信息确定是否在第一DRX周期内进行RRM测量，包括：
若第二指示信息指示网络设备在第二DRX周期可能发送CSI-RS，且终端设备在所述第一DRX检测PDCCH，则终端设备在所述第一DRX周期内进行RRM测量；
若第二指示信息指示网络设备在第二DRX周期可能发送CSI-RS，且终端设备在第一DRX周期不检测PDCCH，则终端设备不在第一DRX周期内进行RRM测量。
具体地，网络设备在第二DRX周期可能发送CSI-RS，则不能够确定在第二DRX周期是否发送CSI-RS，若终端设备在第一DRX周期检测PDCCH，则要进入激活状态，终端设备可以在第一DRX周期内进行RRM测量。若终端设备在第一DRX周期不检测PDCCH，则终端设备不开启持续时间定时器，终端设备根据上一次接收的第二指示信息确定网络设备是否在第一DRX周期内发送CSI-RS，例如，当第二指示信息用1个比特表示，且上一次接收的第二指示信息该比特为0时，则网络设备在第一DRX周期可以不发送CSI-RS，则终端设备可以不在第一DRX周期内进行RRM测量，当上一次接收的第二指示信息该比特为1时，则终端设备确定网络设备在第一DRX周期发送CSI-RS，则终端设备可以在第一DRX周期内进行RRM测量。
情况5
当指示信息包括第一指示信息和第二指示信息时，终端设备根据在第一DRX周期是否检测PDCCH和指示信息确定是否在第一DRX周期内进行RRM测量，包括：
若第一指示信息指示网络设备在第一DRX周期可能发送CSI-RS，且第二指示信息指示网络设备在第二DRX周期可能发送CSI-RS，且终端设备在第一DRX周期不检测PDCCH，则终端设备确定网络设备在第一DRX周期内可以不发送CSI-RS，则终端设备不在第一DRX周期内进行RRM测量；
若第一指示信息指示网络设备在第一DRX周期可能发送CSI-RS，且第二指示信息指示网络设备在第二DRX周期确定发送CSI-RS，且终端设备在第一DRX周期不检测PDCCH，则终端设备确定网络设备在第一DRX周期内可以不发送CSI-RS，则终端设备不在第一DRX周期内进行RRM测量；
若第一指示信息指示网络设备在第一DRX周期确定发送CSI-RS，且第二指示信息指示网络设备在第二DRX周期可能发送CSI-RS，且终端设备在第一DRX周期不检测PDCCH，则终端设备也可以在第一DRX周期内进行RRM测量；
若第一指示信息指示网络设备在第一DRX周期可能发送CSI-RS，且第二指示信息指示网络设备在所述第二DRX周期可能发送CSI-RS，且根据节能信号的接收情况确定所述终端设备在第一DRX周期唤醒，则终端设备确定网络设备在第一DRX周期内发送CSI-RS，则终端设备可以在第一DRX周期内进行RRM测量。
若第一指示信息指示网络设备在第一DRX周期确定发送CSI-RS，且第二指示信息指示网络设备在所述第二DRX周期确定发送CSI-RS，且根据节能信号的接收情况确定所述终端设备在第一DRX周期不检测PDCCH，则终端设备也可以不在第一DRX周期内进行RRM测量；
若第一指示信息指示网络设备在第一DRX周期可能发送CSI-RS，且第二指示信息指示网络设备在所述第二DRX周期确定发送CSI-RS，且根据节能信号的接收情况确定所述终端设备在第一DRX周期检测PDCCH，则终端设备确定网络设备在第一DRX周期内发送CSI-RS，但终端设备也可以不在第一DRX周期内进行RRM测量；
若第一指示信息指示网络设备在第一DRX周期确定发送CSI-RS，且第二指示信息指示网络设备在所述第二DRX周期可能发送CSI-RS，且根据节能信号的接收情况确定所述终端设备在第一DRX周期检测PDCCH，则终端设备可以在第一DRX周期内进行RRM测量；
若第一指示信息指示网络设备在第一DRX周期确定发送CSI-RS，且第二指示信息指示网络设备在所述第二DRX周期确定发送CSI-RS，且根据节能信号的接收情况确定所述终端设备在第一DRX周期检测PDCCH，则终端设备也可以不在第一DRX周期内进行RRM测量。
可选地，该第一指示信息和第二指示信息可以一起发送给终端设备，也可以分开单独发送。
例如，该第一指示信息、第二指示信息和节能信号一同发送给终端设备。
再例如，第二指示信息和节能信号一同发送给终端设备。
情况6
当指示信息包括第一指示信息时，终端设备根据在第一DRX周期是否检测PDCCH 和指示信息确定是否在第一DRX周期内进行RRM测量，包括：
终端设备根据在第一DRX周期是否检测PDCCH和第一指示信息，确定网络设备在第二DRX周期内发送CSI-RS的可能性；
终端设备根据网络设备在第二DRX周期内发送CSI-RS的可能性，确定是否在第一DRX周期内进行RRM测量。
具体地，可以根据在第一DRX周期是否检测PDCCH和第一指示信息，确定网络设备在第二DRX周期内发送CSI-RS的可能性。
例如，可以按照以下协议规定，确定网络设备在第二DRX周期内发送CSI-RS的可能性：
若第一指示信息指示所述网络设备在第一DRX周期可能发送CSI-RS，且终端设备在第一DRX周期检测PDCCH，此时，终端设备由于要在第一DRX周期检测PDCCH必然要进入激活状态，所以之前第一指示信息指示的网络设备在第一DRX周期可能发送CSI-RS变成确定发送CSI-RS，则终端设备确定网络设备在第二DRX周期内可能发送CSI-RS；
若第一指示信息指示网络设备在第一DRX周期可能发送CSI-RS，且终端设备在第一DRX周期不检测PDCCH，此时，终端设备由于不需要在第一DRX周期检测PDCCH，所以之前第一指示信息指示的网络设备在第一DRX周期可能发送CSI-RS表示网络设备可以不发送CSI-RS，则终端设备确定网络设备在第二DRX周期内一定发送CSI-RS；
若第一指示信息指示网络设备在第一DRX周期一定发送CSI-RS，则终端设备确定网络设备在第二DRX周期内可能发送CSI-RS。
进一步地，终端设备根据网络设备在第二DRX周期内发送CSI-RS的可能性，确定是否在第一DRX周期内进行RRM测量，可以包括以下方式：
若网络设备在第二DRX周期可能发送CSI-RS，且确定终端设备在第一DRX周期检测PDCCH，则终端设备在第一DRX周期内进行RRM测量；
若网络设备在第一DRX周期可能发送CSI-RS，且确定终端设备在第一DRX周期不检测PDCCH，则终端设备不在第一DRX周期内进行RRM测量。
本申请实施例能够通过指示信息指示网络设备在第一DRX周期和/或第二DRX周期是否发送CSI-RS，并且根据指示信息(以及结合节能信号的具体指示)确定是否在第一DRX周期内进行RRM测量，使得终端设备对CSI-RS的测量更加灵活，终端设备可以根据指示信息决策在当前的第一DRX是否进行RRM测量，从而有利于节约终端设备的能耗。
本申请还提供一种通信方法500，能够提供给网络设备和终端设备在DRX周期内不发送/测量CSI-RS的可能性，从而有助于节省终端设备和网络设备的功耗。
图12是本申请实施例的通信方法500的示意性流程图。图12所示的方法500包括步骤510至步骤530。
步骤510，终端设备根据节能信号的接收情况，确定N个DRX周期是否检测PDCCH，N为大于1的整数。
步骤520，终端设备接收指示信息，该指示信息用于指示在该N个DRX周期内网络设备是否发送CSI-RS。
在步骤530中，终端设备根据节能信号的接收情况和指示信息确定是否进行RRM测量。
