Description

无线资源管理测量方法与装置
本申请要求于2019年01月03日提交中国专利局、申请号为201910004585.7、申请名称为“无线资源管理测量方法与装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域，具体涉及一种无线资源管理(Radio Resource Management，RRM)测量方法与装置。
背景技术
移动业务的发展对无线通信的数据速率和效率要求越来越高。在无线通信中，终端设备的功耗是一个重要问题。为了降低终端设备的功耗，3GPP标准协议在长期演进(long term evolution，LTE)系统中引入非连续接收(discontinuous reception，DRX)机制。DRX的基本机制是，为处于连接态的终端设备配置DRX周期(DRX cycle)，DRX周期包括激活期(on duration)和休眠期(opportunity for DRX)。在激活期，终端设备监听并接收下行信号，在休眠期，终端设备不监听也不接收下行信号以节省功耗。
为了进一步降低终端设备的功耗，有人提出在DRX机制中引入功率节省信号。功率节省信号用于指示终端设备在下一个DRX周期的激活期进行休眠或者进行监听与测量。功率节省信号是网络设备基于物理下行控制信道(physical downlink control channel，PDCCH)的测量需求为终端设备配置的。
为了满足无线资源管理(radio resource management，RRM)的目的，网络设备会配置终端设备测量无线资源，这个测量称为RRM测量。
使用功率节省信号后，相对来说，会使终端设备在一个RRM测量周期中睡眠次数增多，可能会出现，终端设备在需要进行RRM测量的DRX周期进行休眠的情形，即导致RRM测量周期内的RRM测量次数减少，会降低RRM测量的测量精度。

除非另有定义，本文所使用的所有的技术和科学术语与属于本申请的技术领域的技术人员通常理解的含义相同。本文中在本申请的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本申请。

在描述本申请实施例之前，下文首先描述DRX机制、功率节省信号、以及RRM测量的概念。
1、DRX机制
基于包的数据流通常是突发性的，在没有数据传输的时候，可以通过关闭终端设备的接收电路来降低功耗，从而提升终端设备的电池使用时间。这就是，不连续接收(discontinuous reception，DRX)机制的由来。
DRX机制的示意图如图1所示，在时域上，时间被分成一个个连续的DRX周期(DRX cycle)。DRX周期包括激活期(on duration)和休眠期(opportunity for DRX)。在激活期，终端设备监听并接收下行信号(例如，物理下行控制信道(PDCCH))，在休眠期，终端设备不监听也不接收下行信号，以节省功耗。
现有技术中，DRX机制的工作状态分为空闲态DRX(Idle-DRX)和连接态DRX(Connected-DRX)，空闲态DRX指的是，为处于空闲态的终端设备配置DRDX周期，连接态DRX指的是，为处于连接态的终端设备配置DRX周期。本申请仅涉及连接态DRX。为了描述的简洁，本文中将连接态DRX简称为DRX，换言之，下文提及的DRX均指连接态DRX。
2、功率节省信号
为了进一步降低终端设备的功耗，有人提出将功率节省信号引入DRX。功率节省信号是网络设备基于PDCCH的测量需求配置到终端设备上的。例如，在终端设备需要在下一个DRX周期的激活期(或者该激活期中的部分时间)监听PDCCH时，网络设备通过功率节省信号指示终端设备在下一个DRX周期的激活期(或者该激活期中的部分时间)监听PDCCH；在终端设备不需要在下一个DRX周期的激活期监听PDCCH时，网络设备通过功率节省信号指示终端设备在下一个DRX周期的激活期进行休眠。
功率节省信号的配置方式可以包括如下两种。
功率节省信号的配置方式一：网络设备通过功率节省信号的不同状态值来指示终端设备在下一个DRX周期的激活期是否休眠。
例如，功率节省信号具有两个状态值“0”和“1”，当功率节省信号的状态值为“0”时表示终端设备在下一个DRX周期的激活期进行休眠，当功率节省信号的状态值为“1”时表示终端设备在下一个DRX周期的激活期监听PDCCH。可以通过一直存在的功率节省信号来指示终端设备在下一个DRX周期的激活期是否休眠。
配置方式一还可描述为：网络设备通过一直存在的功率节省信号来指示终端设备在下一个DRX周期的激活期是否休眠。换言之，无论终端设备是否需要在下一个DRX周期的激活期监听PDCCH，网络设备均会为终端设备配置功率节省信号。
功率节省信号的配置方式二：网络设备通过是否配置功率节省信号来指示终端设备在下一个DRX周期的激活期是否休眠。
例如，当终端设备需要在下一个DRX周期的激活期监听PDCCH时，网络设备为终端设备配置功率节省信号，当终端设备不需要在下一个DRX周期的激活期监听PDCCH时，网络设备不为终端设备配置功率节省信号。终端设备也知道这种指示方式。即在终端设备侧，当检测到功率节省信号时，在下一个DRX周期的激活期监听PDCCH，当在下一个DRX周期到来之前未检测到功率节省信号，在下一个DRX周期的激活期进行休眠。或者，也可以将上述例子描述的情形反过来。
配置方式二还可描述为：网络设备通过间断存在的功率节省信号来指示终端设备在下 一个DRX周期的激活期是否休眠。
网络设备可以通过如下信令中的任一种向终端设备通知功率节省信号的配置方式：无线资源控制(Radio Resource Control，RRC)信令、媒体接入控制控制元素(Media Access Control-Control element，MAC-CE)信令、下行控制信息(Downlink Control Information，DCI)信令、或系统信息(System Information，SI)。
功率节省信号可以为苏醒信号(Wake-up signal，WUS)，也可以为睡眠信号(go-to-sleep signal，DTS)。功率节省信号还可以为其它信号，例如，功率节省信号为下列信号中的任一种：信道状态信息参考信号(channel state information reference signal，CSI-RS)、解调参考信号(demodulation reference signal，DMRS)、跟踪参考信号(tracking reference signals，TRS)或同步信号/物理广播信道块(synchronization signal/physical broadcast channel block，SS/PBCH block)。
功率节省信号可以是序列信号，也可以是数据信号。当功率节省信号为数据信号时，功率节省信号可以为下列中的任一种：DCI、物理下行共享信道(Physical Downlink Shared Channel，PDSCH)、MAC-CE或RRC。
为序列信号。功率节省信号还可以为PDCCH。或者，功率节省信号还可以为
网络设备可以配置功率节省信号为序列信号或者PDCCH。
网络设备可以通过下列信令中的任一种来向终端设备发送功率节省信号：RRC信令、MAC-CE信令。
在DRX机制中引入功率节省信号的方案中，可选地，DRX机制与功率节省信号之间的关联关系，可以由网络设备配置，下发给终端设备。例如，该配置信息可以承载于下列中的任一种：物理广播信道(physical broadcast channel，PBCH)、剩余最小系统信息(remaining minimum system information，RMSI)、系统信息块(system information block，SIB)1、SIB2、SIB3、媒体接入控制控制元素(media access control-control element，MAC-CE)、下行控制信息(down link control information，DCI)、无线资源控制(radio resource control，RRC)以及系统信息。
可选地，DRX机制与功率节省信号之间的关联关系也可以由标准规定，或者由网络设备和终端设备预先约定。
图2为在DRX机制中引入功率节省信号的示意图，在图2中，以功率节省信号为WUS为例。如图2所示，当配置了WUS时，终端设备在DRX周期内对应的时间上进行盲检，如果检测到WUS，唤醒PDCCH检测模块，在DRX周期的激活期进行PDCCH的检测；如果没有检测到WUS，终端设备重新睡眠，直到下一个DRX周期的激活期到达。
作为示例，当功率节省信号与DRX周期的激活期的偏移值(offset)之间的值是固定时，该offset的值可以根据一些情况确定是否发送。
可选地，可以根据上下行数据的传输确定否发送该offset的值。
例如，当功率节省信号遇到上行信号的传输时机时，可以不发送。
可选地，也可以根据与必须传输的下行信号是否冲突确定是否发送功率节省信号。
例如，当与SSB冲突的时候，确定是否发送功率节省信号。当与SSB冲突的时候，可以不发送功率节省信号。当终端设备没有收到功率节省信号的时候，终端设备则需要检测下一个DRX周期的激活期中的数据信号或下一个DRX周期中的数据。
应理解，这样可以避免终端设备遗漏网络设备的调度数据。
或者网络设备不发送功率节省信号，终端设备也不在下一个DRX周期的激活期中检测数据信号，或在下一个DRX周期中检测数据信号。
功率节省信号与DRX周期的激活期之间的偏移值，或者功率节省信号的位置，或者DRX周期中的激活期的位置也可以是变化的。
作为示例，一种变化方式为，根据功率节省信号的存在与否确定；或者根据当功率节省信号与DRX周期的激活期的偏移值(offset)随功率节省信号的指示进行变化；或根据Pre-wake-up window的存在进行变化。
第一种变化的方式是功率节省信号的位置是固定的，DRX周期的起始位置或偏移位置与功率节省信号的位置的相对偏移是变化的，激活期(onDuration)的起始时间与功率节省信号的位置的相对偏移是变化的，DRX周期的起始位置与激活期的起始位置之间可以没有偏移。
第二种变化的方式是功率节省信号的位置是固定的，DRX周期的起始位置是固定的，激活期的起始时间与功率节省信号的位置的相对偏移是变化的。当功率节省信号指示终端设备需要进行测量或进行同步的时候，offset值为offset1；当功率节省信号指示终端设备不需要进行测量或进行同步的时候，offset值为offset2；Offset1＝offset2+Delta_offset。Delta_offset的值可以是配置的，也可以与测量的参考信号持续时间的长度相同。Delta_offset的值可以是配置的。offset2或offset1或Delta offset的值也可以是网络设备配置的，或者协议规定的或者是根据参数推导出来的。网络设备配置的值可以是基于时隙或者基于符号或者是基于子帧或者是基于帧的。该offset1或offset2或Delta的值可以为1～19中全部整数的部分或全部。该偏移值的单位可以为帧，子帧，时隙或符号中的任意一种。
功率节省信号的位置可以有K2个。K2的值可以为1～64中的全部整数中的部分或全部。
例如，网络设备可以配置K2的值为8，其中8为MAC-CE激活的PDSCH的传输配置指示数目。
再例如，K2的值可以与网络设备通过RRC信令配置的PDCCH或者PDSCH的传输配置数目的指示数目相同。
可选地，网络设备可以在配置的每一个功率节省信号的位置发送功率节省信号，也可以在一个或多个配置的功率节省信号的位置不进行发送功率节省信号。
发送功率节省信号的位置可以由网络设备配置。例如，网络设备可以为终端设备配置发送功率节省信号的位置的索引。
这些功率节省信号的位置的配置方式可以有多种。
例如，直接配置功率节省信号的位置。
再例如，间接配置功率节省信号的位置，例如，可以通过时间偏移来配置功率节省信号的位置，该时间偏移可以是相对于不同时隙、不同帧、不同符号的位置的偏移；或者，该时间偏移可以是相对于不同时隙、相同帧、不同符号的位置的偏移；或者，该时间偏移可以是相对于相同时隙、相同帧、不同符号的位置的偏移。该时间偏移的值可以相同，也可以是不同的。该时间偏移可以随着功率节省信号的配置进行配置，配置的参数可以包含配置信号的索引，周期和偏移。该时间偏移也可以相对于相同的一个激活期或DRX周期 的起始位置进行配置。网络设备可以同时与终端设备配置多个激活的功率节省信号位置或者配置多个发送功率节省信号的位置。网络设备可以设置一个或多个主信号，用于指示该终端设备是否在下一个DRX周期中的激活期进行睡眠，其他功率节省信号用于该终端设备的测量。
本申请实施例中提及的网络设备配置可以是通过下列中任一项实现：通过RRC信令进行配置、通过MAC-CE信令进行配置、通过DCI信令进行配置、通过MAC-CE信令和RRC信令进行配置、通过MAC-CE信令和DCI进行配置、通过RRC信令和DCI信令进行配置、通过RRC信令和MAC-CE信令以及DCI信令进行配置。
3、RRM测量
为了满足无线资源管理(RRM)的目的，网络设备配置终端设备进行无线资源测量，这个测量称为RRM测量。
RRM测量中需要测量的测量量可以包括同步信号块的参考信号接收功率(reference signal receiving power，RSRP)、参考信号接收质量(reference signal receiving quality，RSRQ)、信号与干扰和噪声的比值(signal to interference plus noise ratio，SINR)或参考信号强度指示(reference signal strength indicator，RSSI)等。或者，该测量量可以包括信道状态信息参考信号(channel state information-reference signal，CSI-RS)的RSRP、RSRQ、SINR或RSSI等。或者，该测量量可以是其参考信号的RSRP、RSRQ、SINR或RSSI等。或者，该测量量可以是其他测量量，例如信道状态信息(channel status information，CSI)、信道质量指示(channel quality indicator，CQI)、预编码矩阵指示(precoding matrix indicator，PMI)、预编码类型指示(precoding type indicator，PTI)、分集指示(rank indication，RI)和CSI-RS资源索引(CSI-RS index，CRI)中的至少一项。
其中，同步信号块也可以称为同步信号/物理广播信道(synchronization signal/physical broadcast channel block，SS/PBCH)块。同步信号块中可以包括如下中至少一个：PBCH，主同步信号(primary synchronization signal，PSS)，辅同步信号(secondary synchronization signal，SSS)。同步信号块也可以称为SSB或SS/PBCH block或SS block。
终端设备在进行RRM测量之后，当满足报告标准时，会将测量结果报告给网络设备。例如，当SSB的RSRP/RSRQ值大于由网络设备配置的阈值时，终端设备可以出发测量报告。
作为示例而非限定，在连接态的终端设备的RRM测量中，RAN4(负责LTE无线接入网的标准化工作的一个工作组)规定的RRM测量周期如表1和表2所示。如表1所示，针对频段FR1，当没有设置DRX周期或者DRX周期小于320ms时，RRM测量周期的最小值为200ms。如表2所示，针对频段FR2，当没有设置DRX周期或者DRX周期小于320ms时，RRM测量周期的最小值为400ms。

Figure PCTCN2019129918-appb-000002
在表1中，max()表示求最大值函数，f()表示向上取整函数或向下取整函数，例如f()为floor()或ceil()，K p表示根据频率确定的常数。基于同步信号块的RRM测量时间配置(SS block based RRM measurement timing configuration，SMTC)周期表示基于RRM的同步信号/物理广播信道块测量定时配置(SS/PBCH Block Measurement Timing Configuration，SMTC)的周期。

Figure PCTCN2019129918-appb-000003
在表2中，max()表示求最大值函数，f()表示向上取整函数或向下取整函数，例如f()为floor()或ceil()，K p表示根据频率确定的常数，M meas_period_w/o_gaps表示根据功率类型确定的常数，K RLM表示根据测量间隙确定的常数。NOTE 1表示，如果为不同小区配置了不同的SMTC周期，则max()中的SMTC周期指的是所识别的小区的SMTC周期。
通常，RRM测量要求一定的测量精度，本文中将其称为RRM测量精度。RRM测量精度与RRM测量周期内的测量样本的数量有关。例如，RRM测量精度可以表示为，测量波动幅度不超过一定值，测量波动幅度指的是测量功率的波动幅度。例如，RRM测量精度表示测量波动幅度不超过+-4dB、+-6dB或+-9dB。其中，一个RRM测量周期内的测量样本的数量越大，测量波动幅度越小，RRM测量精度越高，反之亦然。因此，可以认为一定的RRM测量精度对应RRM测量周期内一定数量的测量样本。例如，要满足RRM测量精度，在320ms的RRM测量周期内，需要测量5个测量样本。
可以满足RRM测量精度的，一个RRM测量周期内的测量样本的数量，可以被称为满足RRM测量精度的最小测量次数。
测量样本表示一个或多个信号进行RRM测量得到的结果。例如，一个信号进行RRM测量得到的结果可以看作是一个测量样本。或者，多个信号进行RRM测量得到的结果可以看作是一个测量样本。再例如，一个CSI-RS集合中所有CSI-RS进行RRM测量得到的结果可以算做一个测量样本。再例如，半帧内所有SSB进行RRM测量得到的结果可以算做一个测量样本。
例如，RRM测量精度可以根据RRM测量中的测量量(如前文所述)的测量精度进行确定。
上述可知，为了满足RRM测量精度，在一个RRM测量周期内，终端设备需要在该RRM测量周期中进行一定数量的测量样本。
前文已述，使用功率节省信号时，会使终端设备在一个RRM测量周期中睡眠次数增多，这可能会导致，终端设备在需要进行RRM测量的DRX周期进行休眠的情形。这种情形会降低RRM测量的测量精度。
作为示例，如图3所示，假设DRX周期为40ms，SMTC周期为40ms，RRM测量周期为320ms，RRM测量周期内包括8个DRX周期。根据测量精度的要求，需要在RRM测量周期内进行5次测量。由于功率节省信号的指示，终端设备在5个DRX周期进行休眠，只在3个DRX周期内醒来进行监听和测量，即终端设备在RRM测量周期内只进行了3次测量，如图3所示。因此，图3所示的RRM测量降低了RRM测量的测量精度。
针对上述问题，本申请实施例提出一种RRM测量方案，可以在兼顾终端设备的能耗的同时，在一定程度上提高RRM测量的测量精度。
应理解，图1至图3，以及上文结合图1至图3的描述，均是为了更好地理解本申请实施例而给出的示例性描述，对本申请实施例没有限定。
图4为本申请实施例提供的RRM测量方法400的示意性流程图。该方法400的执行主体可以为终端设备或芯片或集成电路。该方法400包括如下步骤。
410，在RRM测量周期内，在至少一个被网络设备指示休眠的DRX周期的激活期进行RRM测量。
在至少一个被网络设备指示休眠的DRX周期的激活期进行RRM测量，表示，在一个或多个被网络设备指示休眠的DRX周期的激活期进行RRM测量。例如，终端设备可以在选择任一个或多个被网络设备指示休眠的DRX周期的激活期进行RRM测量。
网络设备根据监听PDCCH的需求来指示终端设备是否在DRX周期的激活期进行休眠。例如，网络设备在不需要监听PDCCH时，指示终端设备在DRX周期的激活期休眠，在需要监听PDCCH时，指示终端设备在DRX周期的激活期苏醒。
网络设备可以通过功率节省信号指示终端设备在DRX周期的激活期进行休眠或苏醒。
可选地，如图1所示，该方法400还包括：420，接收网络设备发送的功率节省信号。
该功率节省信号可以包括苏醒信号(WUS)或者睡眠信号(GTS)或者序列信号。关于功率节省信号以及功率节省信号的配置方式的描述，详见前文，这里不再赘述。
网络设备指示在DRX周期的激活期休眠表示，指示终端设备在DRX周期的激活期不监听PDCCH，网络设备指示在DRX周期的激活期苏醒表示，指示终端设备在DRX周期的激活期监听并接收PDCCH。
现有技术中，终端设备在被网络设备指示休眠的所有DRX周期的激活期进行休眠，如果在一个RRM测量周期内，终端设备休眠的DRX周期的数目较多，则进行RRM测量的次数较少，可能会导致RRM测量的测量精度降低。
在本申请实施例中，通过在至少一个被网络设备指示休眠的DRX周期的激活期进行RRM测量，相比于现有技术，可以增加RRM测量周期内的RRM测量次数，从而有利于提高RRM测量的测量精度。
本申请实施例中的RRM测量周期，可以由网络设备配置。例如，网络设备可以通过下列中任一种为终端设备配置RRM测量周期：无线资源控制(radio resource control，RRC)信令、媒体接入控制控制元素(media access control-control element，MAC-CE)信令、系 统信息进行配置。
RRM测量周期的大小可以根据DRX周期的大小确定。例如，RRM测量周期的大小通过前文结合表1或表2描述的方式确定。
RRM测量周期还可以是配置参数推导出来的倍数。例如，配置参数推导的一种方式为M1*N1*4*T，其中T表示的DRX周期，M1和N1表示常数。再例如，RRM测量周期的最大值可以不超过10.24s。
该倍数的值可以由网络设备配置。例如该倍数的值可以为整数1～32中部分值或全部值中的任意一个整数。作为示例，网络设备可以根据终端设备的速度配置该倍数的值。
网络设备也可以配置终端设备在RRM测量周期内测量的样本数目，可以配置的值为1,2,3,4,5,6,7,8中的部分或者全部的值。
网络设备在配置该倍数的值和/或样本数目的时候，可以通过测量目标进行配置。例如，网络设备将该倍数的值和/或样本数目与SSB的频率进行一起配置。
本申请实施例中的DRX周期的激活期，表示DRX周期的计时期间。对于长DRX周期，DRX周期的激活期可以表示为On duration Time，对于短DRX周期，DRX周期的激活期可以表示Inactive Time。
本申请实施例中的RRM测量，如前文描述的RRM测量，这里不再赘述。
可选地，在一些实施例中个，步骤410包括：在X个被网络设备指示休眠的DRX周期的激活期进行RRM测量，X的取值使得，在RRM测量周期内的RRM测量次数不小于满足RRM测量精度的最小测量次数。
RRM测量周期内的RRM测量次数，指的是，RRM测量周期内的测量样本的数量。下文将描述的DRX周期的激活期内的RRM测量次数，指的是，DRX周期的激活期内的测量样本的数量。其中，测量样本表示一个或多个信号进行RRM测量得到的结果。例如，一个信号进行RRM测量得到的结果可以看作是一个测量样本。或者，多个信号进行RRM测量得到的结果可以看作是一个测量样本。再例如，一个CSI-RS集合中所有CSI-RS进行RRM测量得到的结果可以算做一个测量样本。再例如，半帧内所有SSB进行RRM测量得到的结果可以算做一个测量样本。
满足RRM测量精度的最小测量次数，指的是，为了满足RRM测量精度，在RRM测量周期内需要测量的测量样本的最小数量。如前文描述，RRM测量精度可以根据RRM测量的测量量的测量精度进行确定。
满足RRM测量精度的最小测量次数可以由网络设备预配置，也可以通过协议规定。例如，满足RRM测量精度的最小测量次数为8、7、6、5、4、3、2或1中的任一种。
下文提及的最小测量次数均指满足RRM测量精度的最小测量次数。
可选地，在本实施例中，X的取值也根据具体需求确定。
本申请实施例，通过在至少一个被网络设备指示休眠的DRX周期的激活期进行RRM测量，使得在RRM测量周期内的RRM测量次数不小于满足RRM测量精度的最小测量次数，从而可以有效提高RRM测量的测量精度。
可选地，在一些实施例中，步骤410包括：在RRM测量周期内，在所有被网络设备指示休眠的DRX周期的激活期均进行RMM测量。
本申请实施例，可以在较大程度上提高RRM测量的测量精度。
可选地，如图5所示，在一些实施例中，该方法400包括如下步骤。
410，在RRM测量周期内，在至少一个被网络设备指示休眠的DRX周期的激活期进行RRM测量。
430，在该RRM测量周期内，在至少一个DRX周期之外的其它被网络设备指示休眠的DRX周期的激活期进行休眠。
换言之，在本申请实施例中，终端设备在一部分被网络设备指示休眠的DRX周期的激活期进行休眠，在另一部分被网络设备指示休眠的DRX周期的激活期进行RRM测量。
在本申请实施例中，通过在一部分被网络设备指示休眠的DRX周期的激活期进行RRM测量，相比于现有技术，可以增加一个RRM测量周期内的RRM测量次数，从而可以在一定程度上提高RRM测量的测量精度；此外，通过在另一部分被网络设备指示休眠的DRX周期的激活期进行休眠，可以降低终端设备的能耗。
在本申请实施例中，可以采用多种方式实现，在至少一个被网络设备指示休眠的DRX周期的激活期进行RRM测量。
可选地，作为第一种实现方式，如图6所示，步骤410包括如下步骤411a和412a。
411a，在RRM测量周期内，每当出现一个被网络设备指示苏醒的DRX周期，将计数器的计数值K减L1，L1为整数。
计数值K的初始值小于或等于RRM测量周期内包括的DRX周期的数目。例如，RRM测量周期内包括8个DRX周期，则计数值K的初始值可以为5或6或7。
可选地，计数器的计数值K的初始值等于最小测量次数所需的DRX周期的个数。
下面将描述计数器的计数值K的初始值的获取方式，以及L1的取值的确定方式。
记计数值K的初始值为N，可以通过如下步骤计算N的取值。
步骤1)，获取RRM测量周期中每个DRX周期内的平均测量次数S。
当RRM测量周期中每个DRX周期的测量次数相同时，S等于RRM测量周期中任一个DRX周期的测量次数。
当RRM测量周期中不同DRX周期的测量次数不同时，可以估计RRM测量周期内的平均测量次数S。
例如，将RRM测量周期中Y个DRX周期的平均测量次数作为S的值，Y小于RRM测量周期包括的所有DRX周期的总数目。例如，根据如下公式确定S的取值。
S＝f1(M1/Y)，
其中，M1表示Y个DRX周期的总测量次数。f1(M1/Y)可以为如下函数中的任一个：floor(M1/Y)、ceil(M1/Y)、或M1/Y。函数floor()表示向下取整，或者说向下舍入，即floor(M1/Y)表示，不大于M1与Y的商的最大整数。函数ceil()表示向上取整，即ceil(M1/Y)表示，不小于M1与Y1的商的最小整数。应理解，在M1与Y可以整除的情形下，f1(M1/Y)可以为M1/Y，否则，应该为floor(M1/Y)或ceil(M1/Y)。
例如，Y个DRX周期可以为RRM测量周期中最后Y个DRX周期，或者，也可以为RRM测量周期中其它位置上的Y个DRX周期。再例如，Y等于1。
步骤2)，根据最小测量次数与平均测量次数，计算N的取值。其中，最小测量次数可以由网络配置给终端设备，也可以通过协议规定。
例如，根据如下公式确定N的取值。
N＝f(M/S)，
其中，M表示最小测量次数。f(M/S)可以为如下函数中的任一个：floor(M/S)、ceil(M/S)、或M/S。函数floor()表示向下取整，或者说向下舍入，即floor(M/S)表示，不大于M与S的商的最大整数。函数ceil()表示向上取整，即ceil(M/S)表示，不小于M与S的商的最小整数。应理解，在M与S可以整除的情形下，f(M/S)可以为M/S，否则，应该为floor(M/S)或ceil(M/S)。
上面描述了通过计算的方式确定N的取值。
可选地，还可以根据经验值确定N的取值，例如，假设一个RRM测量周期内包括8个DRX周期，按照经验，规定需要在5个DRX周期的激活期进行RRM测量，即N等于5。
可选地，当RRM测量周期中每个DRX周期的测量次数相同时，可以采用计算的方式确定N的取值；当RRM测量周期中不同DRX周期的测量次数不同时，可以按照经验值的方式确定N的取值。
N的值可以由终端设备上报给网络设备。或者，N的值可以由网络设备配置给终端设备。
L1的取值根据如下情况而定。
情况一，当RRM测量周期中每个DRX周期的激活期的RRM测量次数相同，L1等于1。
情况二，当RRM测量周期内不同DRX周期的激活期的RRM测量次数不同，L1的值根据被网络设备指示苏醒的DRX周期的激活期的RRM测量次数，与RRM测量周期中倒数第K个DRX周期的激活期的RRM测量次数确定。
在情况二中，当被指示苏醒的DRX周期的激活期的RRM测量次数小于倒数第K个DRX周期的激活期的RRM测量次数时，L1等于0；当被指示苏醒的DRX周期的激活期的RRM测量次数等于或大于倒数第K个DRX周期的激活期的RRM测量次数时，L1等于1，或者L1为大于1的整数。
例如，记倒数第K个DRX周期内的RRM测量次数为a1，倒数第K-1个DRX周期内的RRM测量次数为a2，倒数第K-2个DRX周期内的RRM测量次数为a3，记被网络设备指示苏醒的DRX周期的RRM测量次数为b。当b小于a1时，L1等于0。当b等于a1时，L1等于1。当b大于a1时，L1等于或大于1。再例如，在b大于a1的情况下，当b小于a1与a2之和时，L1等于1；当b等于a1与a2之和时，L1可以等于2；当b大于a1和a2之和时，L1可以等于或大于2。再例如，在b大于a1与a2之和的情况下，当b小于a1、a2和a3之和时，L1等于2；当b等于a1、a2和a3之和时，L1等于3；当b大于a1、a2和a3之和时，L1可以等于或大于3。以此类推，不再枚举。
可选地，在情况二中，确定L1的取值的另一种实现方式为，根据被指示醒来的DRX周期内的RRM测量次数b与倒数K个DRX周期中的平均测量次数c，确定L1的取值。当b小于c时，L1等于0。当b等于c时，L1等于1。当b大于c时，L1大于1，例如，L1等于floor(b/c)，floor(b/c)表示对b与c的商向下取整。
412a，当RRM测量周期内未到达的DRX周期的数目与K的值相等时，在RRM测量周期的倒数K个DRX周期的激活期均进行RRM测量，倒数K个DRX周期中包括被网 络设备指示休眠的DRX周期。
应理解，在完成步骤412a之后，RRM测量周期中倒数K个DRX周期内的RRM测量次数与倒数第K个DRX周期之前的DRX周期内的RRM测量次数等于或大于最小测量次数。
在完成步骤412a之后，RRM测量周期中倒数K个DRX周期可以包括下列中的任一种或多种：被网络设备指示休眠的DRX周期，被网络设备指示醒来的DRX周期，未被网络设备指示休眠或醒来的DRX周期。RRM测量周期中倒数第K个DRX周期之前的DRX周期中进行RRM测量的DRX周期均为被网络设备指示苏醒的DRX周期。
图7为图6所示实施例的一个具体例子。在图7中，RRM测量周期中每个DRX周期的RRM测量次数相同。RRM测量周期等于320ms，DRX周期等于40ms，一个RRM测量周期包括8个DRX周期，每个DRX周期的RRM测量次数均为1。网络设备通过功率节省信号指示终端设备在DRX周期的激活期进行休眠或苏醒，如图7所示，标有“休眠”标识的DRX周期表示被功率节省信号指示休眠的DRX周期。假设计数值K的初始值N等于5，实现在RRM测量周期的倒数K个DRX周期的激活期均进行RRM测量的方式如下：
第1个DRX周期被指示醒来，将K的值减1更新为4；第2个DRX周期被指示休眠，将K的取值维持为4；第3个DRX周期被指示休眠，将K的取值维持为4；第4个DRX周期被指示醒来，将K的取值减1更新为3；第5个DRX周期被指示休眠，将K的取值维持为3，这时，RRM测量周期中未到达的DRX周期的个数为3，即等于K的取值，则在RRM测量周期的最后3个DRX周期内均进行RRM测量。
如图7中，在本实施例中，虽然第6个和第8个DRX周期是被指示为休眠，但是，终端设备会在第6个和第8个DRX周期的激活期进行RRM测量。
图7所示实施例，在满足RRM测量精度的情况下，还可以降低终端设备的能耗。
图8为图6所示实施例的另一个具体例子。在图8中，RRM测量周期等于320ms，DRX周期等于40ms，一个RRM测量周期内包括8个DRX周期。不同DRX周期的RRM测量次数不完全相同，第1、3、5和7个DRX周期中的测量次数为2，第2、4、6和8个DRX周期中的测量次数为1。网络设备通过功率节省信号指示终端设备在DRX周期的激活期进行休眠或苏醒，如图8所示，标有“休眠”标识的DRX周期表示被功率节省信号指示休眠的DRX周期。假设计数值K的初始值N等于5，实现在RRM测量周期的倒数K个DRX周期的激活期均进行RRM测量的方式如下：
第1个DRX周期被指示醒来，该醒来的DRX周期的激活期的测量次数为2，倒数第K(这时K的值为5)个DRX周期的测量次数为1，倒数第K-1个DRX周期的测量次数为1，这时，可以将K的值减去2，即K的值更新为3。此时，RRM测量周期中未处理的DRX周期的个数为7。
第2个DRX周期被指示休眠，K的取值维持为3，此时，RRM测量周期中未处理的DRX周期的个数为6。第3个DRX周期被指示休眠，K的取值维持为3，RRM测量周期中未处理的DRX周期的个数为5。
第4个DRX周期被指示醒来，该醒来的DRX周期的激活期的测量次数为1，倒数第K(这时K的值为3)个DRX周期的测量次数为1，这时，可以将K的值减1，即K的 值更新为2，此时，RRM测量周期中未处理的DRX周期的个数为4。
第5个DRX周期被指示休眠，K的取值维持为2，此时，RRM测量周期中未处理的DRX周期的个数为3。
第6个DRX周期被指示休眠，K的取值维持为2，此时，RRM测量周期中未处理的DRX周期的个数为2，即RRM测量周期中未处理的DRX周期的个数等于K的值，这种情况下，确定在RRM测量周期的最后2个DRX周期内均进行RRM测量。
如图8中，在本实施例中，虽然第8个DRX周期是被指示为休眠，但是，终端设备会在第8个DRX周期的激活期进行RRM测量。
图8所示实施例，在满足RRM测量精度的情况下，还可以降低终端设备的能耗。
因此，本申请实施例，在较大程度上保证RRM测量的测量精度的情况下，还可以降低终端设备的能耗。
有些情况下，在RRM测量周期的最后一个DRX周期，不进行RRM测量。针对这种情况下，在图6所示实施例的步骤412a可以替换为：当RRM测量周期内除最后一个DRX周期之外、未到达的DRX周期的数目与K的值相等时，在RRM测量周期的倒数第K+1个DRX周期至倒数第二个DRX周期的激活期均进行RRM测量。例如，倒数第K+1个DRX周期至倒数第二个DRX周期中包括被网络设备指示休眠的DRX周期。
可选地，作为第二种实现方式，如图9所示，步骤410包括如下步骤411b和412b。
411b，在RRM测量周期内，每当出现一个被网络设备指示苏醒的DRX周期时，将计数器的计数值R的值减L2，L2等于被指示苏醒的DRX周期的激活期的RRM测量次数，计数器的计数值R的初始值为RRM测量周期内的RRM测量次数。
可选地，计数器的计数值R的初始值等于满足RRM测量精度的最小测量次数。
412b，当RRM测量周期内未到达的倒数G个DRX周期中的RRM测量次数之和等于或大于R的值，且倒数G-1个DRX周期中的RRM测量次数之和等于或小于R的取值时，在倒数G个DRX周期的激活期均进行RRM测量，倒数G个DRX周期中包括被网络设备指示休眠的DRX周期。
应理解，在完成步骤412b之后，RRM测量周期中倒数G个DRX周期内的RRM测量次数与倒数第G个DRX周期之前的DRX周期内的RRM测量次数等于或大于最小测量次数。
在完成步骤412b之后，RRM测量周期中倒数G个DRX周期可以包括下列中的一种或多种：被网络设备指示休眠的DRX周期，被网络设备指示醒来的DRX周期，未被网络设备指示休眠或醒来的DRX周期。RRM测量周期中倒数第G个DRX周期之前的DRX周期中进行RRM测量的DRX周期均为被网络设备指示苏醒的DRX周期。
本实施例，可以在较大程度满足RRM测量精度的情况下，还可以降低终端设备的能耗。
应理解，无论RRM测量周期内各个DRX周期的RRM测量次数是否相同，都可以通过第二种实现方式实现步骤410。
有些情况下，在RRM测量周期的最后一个DRX周期，不进行RRM测量。针对这种情况下，在图9所示实施例的步骤412b可以替换为：当RRM测量周期内除最后一个DRX周期之外、未到达的倒数第G+1个至倒数第二个DRX周期中的RRM测量次数之和等于 或大于R的值，且倒数第G个至倒数第二个DRX周期中的RRM测量次数之和等于或小于R的取值时，在倒数第G+1个至倒数第二个DRX周期的激活期均进行RRM测量。例如，倒数第G+1个至倒数第二个DRX周期中包括被网络设备指示休眠的DRX周期。
可选地，作为另一种实现方式，步骤410包括：当RRM测量周期中已被网络设备指示休眠的DRX周期的数目达到阈值时，在RRM测量周期内未到达的网络设备指示休眠的DRX周期的激活期均进行RRM测量。
该阈值小于RRM测量周期内包括的所有DRX周期的总数量。例如，RRM测量周期内包括的所有DRX周期的总数量为8，该阈值可以为2或3。
该阈值可以预配置，也可以根据具体需求而定。
该阈值可以由网络设备配置给终端设备，也可以由终端设备上报给网络设备。
有些情况下，在RRM测量周期的最后一个DRX周期，不进行RRM测量。针对这种情况下，在本实施例中，步骤410可以替换为：当RRM测量周期中已被网络设备指示休眠的DRX周期的数目达到阈值时，在RRM测量周期内除最后一个DRX周期之外、未到达的网络设备指示休眠的DRX周期的激活期均进行RRM测量。
应理解，当终端设备进行RRM测量的测量结果满足一定事件时，终端设备可以向网络设备上报测量结果。在终端设备准备上报测量结果时，如果有可用的上行资源，则可以利用该上行资源上报测量结果，如果没有可用的上行资源，则终端设备向网络设备发送调度请求(scheduling request，SR)以请求上行资源。
本申请实施例中的RRM测量可以包括下列中至少一种：RRM测量、测量结果上报和参考信号的配置。
