具体实施方式
为便于理解本申请实施例提供的方法，在介绍本申请实施例之前，对本申请实施例涉及的一些名词进行解释：
载波聚合(carrier aggregation，CA)：将两个或者两个以上的组分载波(component carrier，CC)聚合在一起以支持更大的传输带宽(如：100兆赫兹(MHz))。其中，每个CC对应一个独立的小区(cell)，可以将1个CC等同于1个小区，每个CC的最大带宽为20MHz。3GPP协议规定一个终端可以被配置多个CC，(如：最多可以被配置5个CC或者32个CC等)，在终端的多个CC中，其中一个CC可以被称为主小区(primary cell，PCell)，是终端进行初始连接建立的小区，或进行无线资源控制(radio resource control，RRC)连接重建的小区，或是在切换(handover)过程中指定的主小区。PCell负责与终端之间的RRC通信。PUCCH只能在PCell上发送。其余CC被称为辅小区(secondary cell，SCell)，SCell是在终端的RRC重配置时添加的，用于提供额外的无线资源。
带宽部分(bandwidth part，BWP)：系统带宽的一部分。系统带宽可以指一个载波的带宽，系统带宽可以很大，如：可以为200MHz或者400MHz，有些终端支持不了这么大的系统带宽，因此网络设备可以给终端配置BWP(系统带宽的一部分)，例如20MHz，终端可以在20MHz上与网络设备进行通信。BWP可以分为下行(downlink BWP，DL BWP)和上行BWP(uplink BWP，UP BWP)。网络设备可以为终端配置多个DL BWP以及多个UL BWP，并且激活(active)至少一个DL BWP和激活至少一个UL BWP，终端在激活的DL BWP上接收网络设备发送的下行信号，包括但不限于下行控制信令，下行数据；终端在激活的UL BWP上发送上行信号，包括但不限于上行控制信令，上行数据，调度请求(scheluing request，SR)，信道探测参考信号(sounding reference signal，SRS)，信道状态信息(channel state information，CSI)/信道质量指示(channel quality indicate，CQI)反馈等等。
非连续接收(discontinuous reception，DRX)：可以称为连接态下的非连续接收(connected  discontinuous reception，C-DRX)。C-DRX基本原理是，RRC_CONNECTED态的终端被配置一个C-DRX周期(cycle)。图1为C-DRX cycle示意图，如图1所示，C-DRX cycle可以由激活期“on duration”和休眠期“opportunity for DRX”组成。在“on duration”时间内，终端监测并接收物理下行控制信道(pysical downlink control channel，PDCCH)；在“opportunity for DRX”时间内，终端不接收PDCCH，以减少功耗。其中，C-DRX的周期大小以及激活期和休眠期的长度，都是由基站配置给终端的。不同CC或者BWP的C-DRX周期可能不同，也可能相同，不予限制。
PDCCH监测：可以指终端接收下行信号，然后在接收的下行信号中的一系列PDCCH候选位置(candidate)上进行盲检，看是否有发给自己的PDCCH。其中，一组PDCCH candidate可以组成一个搜索空间集合(search space set)，搜索空间集合所占用的时频资源位置被称为控制资源集合(control resource set，CORESET)。不同的search space set有不同的监测周期。另外，search space set还可以分为公共搜索空间集合(common search space set)和终端特定的搜索空间集合(UE-specific search space set)两种类型，终端在不同类型的搜索空间集合中会监测携带不同格式(format)的下行控制信息(downlink control information，DCI)的PDCCH，具体监测什么格式的PDCCH，网络侧会在配置该搜索空间集合的时候配置给终端。
跨时隙调度：可以指PDCCH和对应的物理下行数据信道(physical downlink shared channel，PDSCH)的跨时隙调度。示例性的，可以通过PDCCH和对应的PDSCH之间的时间间隔K0(以时隙(slot)为单位)指示PDCCH和对应的PDSCH是否跨时隙调度。
其中，PDCCH和对应的PDSCH之间的时间间隔K0(以时隙(slot)为单位)是由基站动态指示的。具体来说，K0的取值有一个取值集合，该集合是由基站通过RRC信令配置下来的。在某一次调度时，基站会在PDCCH中指示K0的取值集合中的某一个值。如果K0＝0，说明PDCCH与PDSCH在同一个时隙，这称为“同时隙调度”。如果K0>0，说明PDCCH与PDSCH不在同一个时隙，这称为“跨时隙调度”。一般来说，跨时隙调度的时候终端可以避免缓存一些无用数据，因此可以达到节能的目的。当终端知道其被指示的K0值全都大于0的时候，终端肯定是被跨时隙调度的。如果终端的K0取值集合中包含0，那么终端有可能被同时隙调度，此时终端无法达到节能的目的。
短时间休眠：又可以被称为“PDCCH略过”(PDCCH skipping)，指的是终端在若干个时隙、或若干个毫秒、或若干个PDCCH监测时机(PDCCH occasion)内不监测PDCCH的一种行为。一般情况下，PDCCH skipping是由网络侧动态指示的，如：网络设备可以向终端发送一个指示信息，指示终端在若干个时隙、或若干个毫秒、或若干个PDCCH监测时机(PDCCH occasion)内不监测PDCCH，从而达到节能的目的。
测量：终端与基站通信的过程中，终端除了会收发数据之外，还会接收或者发送参考信号(reference signal，RS)，该RS可以用于各种测量，终端可以根据RS进行测量。比如：终端会接收基站发送的信道状态信息参考信号(channel state information reference signal，CSI-RS)，然后使用该信号进行信道状态测量，并根据基站的配置/指示信息，将测量结果反馈给基站，以便基站更好的进行数据调度，如：调节调制和编码方案(modulation and coding scheme，MCS)，确定多输入多输出(multi-input multi-out，MIMO)的预编码矩阵等。又比如：终端会接收基站发送的同步信号块(synchronization signal block，SSB)和/或CSI-RS，然后使用该信号进行无线资源管理(radio resource management，RRM)测量和/或无线链路管理(radio link management，RLM)测量和/或波束管理(beam management，BM)测量，以确定当前的链路质量。
需要说明的是，接收RS和测量，可以认为是两个不同的步骤，即前者为接收信号，后者为对信号 进行处理。也可以认为“测量”即包括接收，也包括对信号进行处理。
目前，为了达到减少终端功耗的目的，可以从两方面进行优化：一是在有业务负载(即有数据需要传输)时，提升数据传输效率；二是在没有业务负载(即无数据需要传输)时，减少终端的能量消耗。针对第二点，在国际电信联盟无线电通信组(international telecommunication union–radiocommunicationssector，ITU-R)的报告中提到，可以通过增大终端处于睡眠状态的比例来达到减少终端的能量消耗的目的。如：网络设备可以向终端发送基于物理下行控制信道(physical downlink control channel，PDCCH)的功耗节省信号(power saving signal)，该功耗节省信号可以用于指示终端在接下来的一个或多个连接态下的非连续接收(connected discontinuous reception，C-CRX)周期(cycle)中处于睡眠状态或唤醒状态；终端接收到该功耗节省信号后，可以根据该功耗节省信号的指示处于睡眠状态或者处于唤醒状态，以便在睡眠状态下，关闭终端的一些电路以达到减少终端的能量消耗的目的。
但是，在终端工作的过程中，除监测PDCCH之外，消耗终端的功耗的操作有很多种，如何最大程度地节省终端的功耗成为亟待解决的问题。为此，本申请实施例提供了一种通信方法，通过功耗节省信号向终端除监测PDCCH之外的其他更多状态。具体的，该方法可以参照下述。
下面结合附图对本申请实施例的实施方式进行详细描述。

图4为本申请实施例提供的一种通信方法流程图，如图4所示，该方法可以包括：
步骤401：网络设备生成功耗节省信号。
其中，网络设备可以为图2中的网络设备。
其中，功耗节省信号可以用于指示终端在N个频率资源单元上的状态，终端可以为与网络设备以CA或多个激活BWP的方式进行通信的任一设备，频率资源单元可以为BWP或者CC或者小区或者其他粒度的频域资源，不予限制。N为大于1的整数，如：N个频率资源单元可以为两个或者两个以上频率资源单元，功耗节省信号可以用于指示终端在两个或者两个以上频率资源单元上的状态。需要说明的是，频率资源单元还可以描述为频域资源单元或者具有其他命名，不予限制。
其中，终端在频率资源单元上的状态可以包括以下至少一项信息：终端监测PDCCH或者不监测PDCCH，终端监测PDCCH的方式，终端进行CSI测量或者不进行CSI测量，终端所处的激活的带宽部分BWP，终端的接收天线数，终端的接收层数，终端的接收最大层数，终端的发射天线数，终端的发射层数，终端的发射最大层数，终端进行跨时隙调度或者不进行跨时隙调度。需要说明的是，本申请不限定终端在频率资源单元上的状态，除上述信息之外，终端在频率资源单元上的状态还可以包括终端进行RRM测量或者不进行RRM测量、终端进行RLM测量或者不进行RLM测量、终端进行BM测量或者不进行BM测量以及其他影响终端的功耗的状态等等，不予限制。
其中，终端监测PDCCH或者不监测PDCCH可以指终端监测PDCCH或者不监测PDCCH。终端监测PDCCH的方式可以包括以下至少一项：终端监测所述PDCCH时监测的搜索空间集合、终端所监测的PDCCH的格式，终端监测所述PDCCH时进行短时间休眠的方式。示例性的，终端所监测的PDCCH的格式可以包括：监测所有PDCCH，或者，监测部分PDCCH(仅监测部分CORESET、部分search space set等)，如：仅监测common search space set中的PDCCH，不监测UE specific search space set；或者，仅监测部分DCI format，如：仅监测common search space set中的组公共PDCCH(group common PDCCH)(如时隙结构指示(slot format indication，SFI))，不监测携带调度信息的PDCCH(scheduling PDCCH)，或者，监测common search space set中所有需要监测的PDCCH。终端监测所述PDCCH时进行短时间休眠的方式包括：短时间休眠的时长和/或短时间休眠指示信息的监测周期等等，不予限制。短时间休眠时长可以指终端在激活期“on duration”内收到短时间休眠指示信息后休眠的时间长短。短时间休眠指示信息的监测周期可以指终端在激活期“on duration”内监测短时间休眠指示的时间间隔。短时间休眠指示信息可以用于指示终端监测PDCCH或者不监测PDCCH。
其中，若终端进行CSI测量，则会消耗终端的功耗，若终端不进行CSI测量，则可以节约终端的功耗。其中，CSI测量的相关描述可参照上述，不再赘述。
其中，终端所处的激活的BWP：可以指终端所处的激活的BWP带宽大小。本申请中，激活的BWP带宽越大，终端越耗能，反之，激活的BWP带宽越小，终端越节能。
其中，终端的接收天线数可以指终端支持的最大接收天线的数量，终端的发射天线数可以指终端支持的最大发射天线的数量。本申请中，终端的接收天线数/终端的发射天线数越大，终端越耗能，终端的接收天线数/终端的发射天线数越小，终端越节能。
其中，终端的接收层数、终端的接收最大层数可以反映终端支持的接收层数。本申请中，终端的接收层数/终端的接收最大层数越大，终端越耗能，终端的接收层数/终端的接收最大层数越小，终端越节能。
其中，终端的发射层数、终端的发射最大层数可以反映终端支持的发射层数。本申请中，终端的发射层数/终端的发射最大层数越大，终端越耗能，终端的发射层数/终端的发射最大层数越小，终端越节能。
其中，终端进行跨时隙调度或者不进行跨时隙调度可以如前所述，当PDCCH和对应的PDSCH之间的时间间隔K0为0时，PDCCH与PDSCH在同一个时隙，终端不进行跨时隙调度，反之，如果K0>0，说明PDCCH与PDSCH不在同一个时隙，终端进行跨时隙调度。
示例性的，本申请各实施例中，功耗节省信号的具体实现形式可参照下述方式一中所述，功耗节省信号包括与状态对应的状态索引值，通过与状态对应的状态索引值指示终端在频率资源单元上的状态；或者，功耗节省信号的具体实现形式可参考下述方式二中所述，功耗节省信号包括与状态包括的信息一一对应的子状态索引值，通过与状态所包括的信息对应的子状态索引值联合指示终端在频率资源单元上的状态。
步骤402：网络设备向终端发送功耗节省信号。
其中，功耗节省信号可以包括在DCI或者RS中。
示例性的，网络设备可以将功耗节省信号承载在N个频率资源单元中的其中一个频率资源单元上向终端发送。如：网络设备可以将功耗节省信号承载在主小区或者PScell或者某一个激活的BWP上向终端发送。
如此，网络设备可以仅通过在一个频率资源单元发送功耗节省信号，指示终端在多个频率资源单元上的状态，无需在每个频率资源单元发送功耗节省信号来指示终端在该频率资源单元上的状态，节省信令开销。
步骤403：终端接收网络设备发送的功耗节省信号，根据接收到的功耗节省信号确定终端在N个频率资源单元上的状态。
示例性的，终端可以在N个频率资源单元中的其中一个频率资源单元上接收网络设备发送的功耗参考信号，如：终端可以在主小区或者PScell或者激活的BWP上接收网络设备发送的功耗节省信号。
本申请中，在功耗节省信号的具体实现形式如下述方式一中所述时，终端可以根据状态与状态索引值间的对应关系，确定终端在N个频率资源单元上的状态；或者，在功耗节省信号的具体实现形式如下述方式二中所述时，终端可以根据状态所包括的信息与子状态索引值间的对应关系，确定终端在N个频率资源单元上的状态。
需要说明的是，本申请实施例不限定功耗节省信号所指示的内容，除指示终端在N个频率资源单元上的状态之外，功耗节省信号还可以用于指示终端在N个频率资源单元上的状态的具体时间或者其他信息，不予限制。如：功耗节省信号可以用于指示一个或多个C-DRX周期内终端在N个频率资源单元上的状态，终端接收到功耗节省信号后，相应的，可以在这一个或者多个C-DRX周期内，将自身状态调整为 功耗节省信所指示的状态。
基于图4所示方法，网络设备可以生成功耗节省信号并发送给终端，以向终端指示除是否监测PDCCH之外的其他指示信息，如：终端监测PDCCH的具体方式(包括终端监测所述PDCCH时监测的搜索空间集合、终端监测的PDCCH的格式，终端监测所述PDCCH时进行短时间休眠的方式)，终端进行CSI测量或者不进行CSI测量，终端的激活的BWP，终端的接收天线数，终端的接收层数，终端的接收最大层数，终端的发射天线数，终端的发射层数，终端的发射最大层数，终端进行跨时隙调度或者不进行跨时隙调度等多个信息，终端接收到功耗节省信号后，可以根据网络设备的指示确定终端在多个频率资源单元上的状态，以便终端将当前自身状态调整为确定后的状态。如此，可以从多个方面控制终端的行为，以便终端在无业务承载时，关闭终端针对多个频率资源单元的一些功能，达到降低终端的功耗的目的。
在图4所示方法中，功耗节省信号的实现方式可以如下述方式一或者方式二所示：
方式一、功耗节省信号包括M个状态索引值，M个状态索引值对应指示终端在N个频率资源单元上的状态，M为正整数，M小于或等于N。
其中，状态索引值可以包括一个或者多个二进制比特数，每个状态索引值可以对应指示终端在一个或者多个频率资源单元上的状态，该状态可以如前所述，包括一项或者多项信息，即每个状态索引值可以联合指示终端在频率资源单元上的状态所包括的多项信息，状态索引值包括的比特数的个数与状态所包括的信息的项数有关，状态索引值的取值范围需要能够指示终端在频率资源单元上的状态所包括的多项信息对应的多种可能组合。示例性的，状态索引值可以与终端在频率资源单元上的状态具有第一对应关系，该第一对应关系可以是预定义的，或者，可以是由网络设备配置的，例如，网络设备可以通过动态信令(如DCI或者其他信令)将第一对应关系配置给终端。
例如，下表一示出了状态索引值与终端在频率资源单元上的状态间的对应关系，终端在频率资源单元上的状态可以包括两项信息：终端监测PDCCH或者不监测PDCCH，终端进行CSI测量或者不进行CSI测量。如表一所示，该状态可以有四种可能情况下，每个情况对应的状态索引值可以为：状态1：不监测PDCCH也不进行CSI测量，状态索引值为00；状态2：不监测PDCCH，但是进行CSI测量，状态索引值为01；状态3：监测部分PDCCH，并且进行CSI测量，状态索引值为10；状态4：监测所有PDCCH，并且进行CSI测量，状态索引值为11。
表一
状态索引值 状态
00 不监测PDCCH也不进行CSI测量
01 不监测PDCCH，但是进行CSI测量
10 监测部分PDCCH，并且进行CSI测量
11 监测所有PDCCH，并且进行CSI测量
其中，当M等于N时，M个状态索引值可以一一对应指示终端在N个频率资源单元上的状态。当M小于N时，M个状态索引值中的至少一个状态索引值对应指示终端在N个频率资源单元中的至少两个频率资源单元上的状态。
例如，终端配置有5个CC：CC1～CC5，功耗节省信号中可以包括5个状态索引值，5个状态索引值可以与5个CC一一对应，一个状态索引值用于指示终端在一个CC上的状态。或者，功耗节省信号中可以包括3个状态索引值index1、index2以及index3，其中，index1可以用于指示终端在CC1上的状态、index2可以用于指示CC2～CC4上的状态，index3可以用于指示终端在CC5上的状态。
又例如，假设第一对应关系中包括3个状态以及3个状态对应的状态索引值：状态1：不监测PDCCH， 状态索引值为00，状态2：仅监测common search space set中的PDCCH，状态索引值为01，状态3：监测所有PDCCH，状态索引值为10。此时，若终端配置有3个小区，网络设备在小区1上向终端发送功耗节省信号，以指示3个小区的状态，如：功耗节省信号中包含如下三个状态索引值：100100，分别对应终端在小区1、小区2、小区3上的状态，则终端根据功耗节省信号包括的状态索引值10和第一对应关系可以获知终端在小区1上监测所有PDCCH，根据功耗节省信号包括的状态索引值01和第一对应关系可以获知在小区2上仅监测common search space set中的PDCCH，根据功耗节省信号包括的状态索引值00和第一对应关系可以获知在小区3上不监测PDCCH。
又例如：假设第一对应关系中包括4个状态以及4个状态对应的状态索引值：状态1：不监测PDCCH，状态索引值为00；状态2：仅监测common search space set中的组公共PDCCH，不监测scheduling PDCCH，状态索引值为01；状态3：监测common search space set中所有需要监测的PDCCH，状态索引值为10；状态:4：监测所有PDCCH，状态索引值为11。此时，若终端配置有3个小区，网络设备在小区1上向终端发送功耗节省信号，以指示3个小区的状态，如：功耗节省信号中包含如下三个状态索引值：110110，分别对应终端在小区1、小区2、小区3上的状态，则终端根据功耗节省信号包括的状态索引值11和第一对应关系可以获知终端在小区1上监测所有PDCCH，根据功耗节省信号包括的状态索引值01和第一对应关系可以获知在小区2上仅监测common search space set中的组公共PDCCH，不监测scheduling PDCCH，状态索引值为01，根据功耗节省信号包括的状态索引值10和第一对应关系可以获知在小区3上监测common search space set中所有需要监测的PDCCH。
又例如，假设第一对应关系中包括4个状态以及4个状态对应的状态索引值：状态1：不监测PDCCH也不进行CSI测量，状态索引值为00；状态2：不监测PDCCH，但是进行CSI测量，状态索引值为01；状态3：监测部分PDCCH，并且进行CSI测量，状态索引值为10；状态4：监测所有PDCCH，并且进行CSI测量，状态索引值为11；此时，若终端配置有4个小区，网络设备在小区1上向终端发送功耗节省信号，以指示4个小区的状态，如：功耗节省信号中包含如下四个状态索引值：11011000，分别对应终端在小区1、小区2、小区3以及小区4上的状态，则终端根据功耗节省信号包括的状态索引值11和第一对应关系可以获知终端在小区1上监测所有PDCCH，并且进行CSI测量，根据功耗节省信号包括的状态索引值01和第一对应关系可以获知在小区2上不监测PDCCH，但是进行CSI测量，根据功耗节省信号包括的状态索引值10和第一对应关系可以获知在小区3上监测部分PDCCH，并且进行CSI测量；根据功耗节省信号包括的状态索引值00和第一对应关系可以获知在小区4上不监测PDCCH也不进行CSI测量。
又例如，终端配置有3个小区：小区1、小区2以及小区3。每个小区上终端各配置了两个BWP，分别是BWP1和BWP2，其中，第一对应关系中包括6个状态以及6个状态对应的状态索引值：状态1：不监测PDCCH也不进行CSI测量，处于BWP1上，状态索引值为000；状态2：不监测PDCCH也不进行CSI测量，处于BWP2上，状态索引值为001；状态3：不监测PDCCH，进行CSI测量，处于BWP1上，状态索引值为010；状态4：不监测PDCCH，进行CSI测量，处于BWP2上，状态索引值为011；状态5：监测PDCCH，进行CSI测量，处于BWP1上，状态索引值为100；状态6：监测PDCCH，进行CSI测量，处于BWP2上，状态索引值为101。此时，网络设备在小区1上向终端发送功耗节省信号，以指示3个小区的状态，如：功耗节省信号中包含如下三个状态索引值：101011000，分别对应终端在小区1、小区2、小区3上的状态，则终端根据功耗节省信号包括的状态索引值101和第一对应关系可以获知终端在小区1上监测PDCCH，进行CSI测量，处于BWP2上，根据功耗节省信号包括的状态索引值011和第一对应关系可以获知在小区2上不监测PDCCH，进行CSI测量，处于BWP2上，根据功耗节省信号包 括的状态索引值000和第一对应关系获知在小区3上不监测PDCCH也不进行CSI测量，处于BWP1上。
又例如，终端配置有3个小区：小区1、小区2以及小区3。每个小区上终端各配置了两个BWP，分别是BWP1和BWP2，其中，第一对应关系中包括8个状态以及8个状态对应的状态索引值：状态1：不监测PDCCH也不进行CSI测量，处于BWP1上，终端的最大层数为2，状态索引值为000；状态2：不监测PDCCH也不进行CSI测量，处于BWP2上，终端的最大层数为2，状态索引值为001；状态3：不监测PDCCH，进行CSI测量，处于BWP1上，终端的最大层数为2，状态索引值为010；状态4：不监测PDCCH，进行CSI测量，处于BWP2上，终端的最大层数为2，状态索引值为011；状态5：监测PDCCH，进行CSI测量，处于BWP1上，终端的最大层数为2，状态索引值为100；状态6：监测PDCCH，进行CSI测量，处于BWP2上，终端的最大层数为2，状态索引值为101；状态7：监测PDCCH，进行CSI测量，处于BWP1上，终端的最大层数为4，状态索引值为110；状态8：监测PDCCH，进行CSI测量，处于BWP2上，终端的最大层数为4，状态索引值为111。此时，网络设备可以在小区1上向终端发送功耗节省信号，以指示3个小区的状态，如：功耗节省信号中包含如下三个状态索引值：110101100，分别对应终端在小区1、小区2、小区3上的状态，则终端根据功耗节省信号包括的状态索引值110和第一对应关系可以获知终端在小区1上监测PDCCH，进行CSI测量，处于BWP2上，终端的最大层数为4；根据功耗节省信号包括的状态索引值101和第一对应关系可以获知在小区2上监测PDCCH，进行CSI测量，处于BWP2上，终端的最大层数为2；根据功耗节省信号包括的状态索引值100和第一对应关系可以获知在小区3上监测PDCCH，进行CSI测量，处于BWP1上，终端的最大层数为2。
方式二、功耗节省信号包括K个子状态索引值组，K个子状态索引值组对应指示终端在N个频率资源单元的状态；K为正整数，K小于或等于N。
其中，每个子状态索引值组包括至少一个子状态索引值，子状态索引值可以为“0”或“1”的二进制数，或者，指示符，不予限制。一个子状态索引值可以指示终端在频率资源单元上的状态所包括的一项信息，子状态索引值组包括的子状态索引值的个数与终端在频率资源单元上的状态所包括的信息的项数是相同的，即在方式二中，可以通过对每项信息进行“单独编码”的形式指示终端在频率资源单元上的状态。例如，若功耗节省信号指示的终端在频率资源单元上的状态包括4项信息，则功耗节省信号中可以包括子状态索引值组，该子状态索引值组可以包括4个二进制比特数，以对应指示这4项信息。需要说明的是，本申请不限定各个子状态索引值在子状态索引值组中的排序。
示例性的，子状态索引值组包括的子状态索引值与终端在频率资源单元上的状态所包括的信息具有第二对应关系，该第二对应关系可以是预定义的或者可以是由网络设备配置的，例如，网络设备可以通过动态信令(如：DCI或者其他信令)将第二对应关系配置给终端。例如，下表二示出了状态索引值与终端在频率资源单元上的状态间的对应关系，终端在频率资源单元上的状态可以包括两项信息：终端监测PDCCH或者不监测PDCCH，终端进行CSI测量或者不进行CSI测量。如表二所示，不监测PDCCH对应的子状态索引值为0；监测PDCCH对应的子状态索引值为1；进行CSI测量对应的子状态索引值为0；不进行CSI测量对应的子状态索引值为1。
表二
子状态索引值 状态包括的信息
0 不监测PDCCH
1 监测PDCCH
0 进行CSI测量
1 不进行CSI测量
其中，当K等于N时，K个子状态索引值组可以一一对应指示终端在N个频率资源单元上的状态。当K小于N时，K个子状态索引值组中的至少一个子状态索引值组对应指示终端在N个频率资源单元中的至少两个频率资源单元上的状态，即可以通过一个子状态索引值组指示终端在两个或者两个以上频率资源单元上的状态。
例如，第二对应关系中包括下述三项信息：监测PDCCH或者不监测PDCCH，终端所处的激活的BWP，终端的最大层数，且每项信息对应的子状态索引值可以为：监测PDCCH为1，不监测PDCCH为0；BWP为BWP1时指示为0，所处BWP为BWP2时指示为1；终端的最大层数为2时指示为0，终端的最大层数为4时指示为1，三项信息对应的子状态索引值的排顺为：监测PDCCH或者不监测PDCCH，终端所处的激活的BWP，终端的最大层数。此时，若终端配置有三个小区：小区1～小区3，网络设备可以在小区1上向终端发送功耗节省信号，以指示3个小区的状态，如：功耗节省信号中包含如下三个状态索引值组：110101100，每个状态索引值组包括三个子状态索引值，分别对应终端在小区1、小区2、小区3上的状态，则终端根据功耗节省信号包括的状态索引值组110和第二对应关系可以获知终端在小区1上监测PDCCH，处于BWP2上，终端的最大层数为2；根据功耗节省信号包括的状态索引值组101和第二对应关系可以获知在小区2上监测PDCCH，处于BWP1上，终端的最大层数为4；根据功耗节省信号包括的状态索引值组100和第二对应关系可以获知在小区3上监测PDCCH，处于BWP1上，终端的最大层数为2。
需要说明的是，网络设备还可以通过上述方式二指示终端在频率资源单元上的其他状态，如：可以指示终端在频域资源单元上是否跨时隙调度等。其中，采用方式二指示终端是否跨时隙调度时，可以采用下述两种实现方式：一、网络设备为终端配置两个K0取值集合，其中一个集合中所有取值都大于0。当网络设备指示终端使用该集合时，即可实现跨时隙调度。如：网络设备为终端仅配置一个K0取值集合，但是为终端指示一个当前被调度时的“最小K0值”。这个“最小K0值”大于0时，即可实现跨时隙调度。K0取值集合为集合1时，子状态索引值为0；K0取值集合为集合2时，子状态索引值为1；或者，二、K0取值集合中的各个取值各自有一个子状态索引值，例如K0＝{0，1，3，5}，对应的子状态索引值分别为0，1，2，3。网络设备为终端指示一个最小K0值的子状态索引值为2，则终端就会知道自己被调度的时候K0值最小也是3，即可实现跨时隙调度。
再比如，网络设备还可以采用方式二所设计的功耗节省信号指示终端在频域资源单元上进行短时间休眠的方式等。比如，功耗节省信号可以包括用于指示终端的短时间休眠方式的子状态索引值(如：一个二进制比特)，使用一个二进制比特指示短时间休眠的时间长度，0代表短休眠时间为2个时隙，1代表短休眠时间为4个时隙。这样，如果功耗节省信号包括的子状态索引值是0，终端之后收到功耗节省信号时，可以根据与终端的短时间休眠方式对应的子状态索引值确定短休眠的时间为2个时隙；如果功耗节省信号包括的子状态索引值是1，终端之后收到功耗节省信号时，就可以根据与终端的短时间休眠方式对应的子状态索引值确定短休眠的时间为4个时隙。或者，使用一个二进制比特指示短时间休眠指示的监测周期，0代表短时间休眠指示信息的监测周期为3个时隙，1代表短时间休眠指示信息的监测周期为5个时隙。这样，如果功耗节省信号包括的子状态索引值是0，终端之后收到功耗节省信号时，可以根据与终端的短时间休眠方式对应的子状态索引值确定以3个时隙为周期监测短时间休眠指示信息；如果功耗节省信号包括的子状态索引值是1，终端收到功耗节省信号时，可以根据与终端的短时间休眠方式对应的子状态索引值确定以5个时隙为周期监测短时间休眠指示信息。
需要说明的是，除上述描述之外，还可以采用方式二将其他项多项信息(如：终端进行CSI测量或者不进行CSI测量，终端的激活的BWP，终端的接收天线数，终端的接收层数，终端的接收最大层数，终端的发射天线数，终端的发射层数，终端的发射最大层数等)一一指示给终端，或者，采用方式一将 其他多项信息联合指示给终端，如：可以确定用于联合指示终端是否跨时隙调度、终端短时间休眠的方式的状态索引值，将该状态索引值包括的功耗节省信号中发送给终端，以便终端根据该状态索引值确定自身在频率资源单元上是否跨时隙调度以及确定自身短时间休眠的方式。
可理解的是，参照上述网络设备通过功耗节省信号向终端指示多个频率资源单元上的状态方法，网络设备还可以将其他影响终端的功耗的状态指示给终端，不予赘述。
