技术领域
本申请涉及移动通信技术领域，尤其涉及一种终端的节能方法及装置。
背景技术
第五代(5th generation，5G)移动网络中，小区带宽大，子载波间隔比较短，与长期演进(Long Term Evolution，LTE)网络相比，终端需要耗费更多的电量用于盲检物理下行控制信道(Physical Downlink Control Channel，PDCCH)信道和接收数据。
现有技术中，一般是由基站向终端配置非连续接收(Discontinuous Reception，DRX)相关参数，然后终端根据DRX的配置，在相应的时间段停止监听基站的寻呼、广播等消息，从而实现终端的节能。
该方法存在的主要问题是：终端在基站指定的时间段进行节能，可能会影响终端的正常业务。
发明内容

第一方面，本申请提供一种终端的节能方法，该方法包括：终端向接入网设备发送节能需求信息，所述节能需求信息包括所述终端需要的时频资源的信息。终端接收来自接入网设备的节能指示，所述节能指示用于指示根据节能需求信息进行节能。终端根据节能需求信息进行节能。基于该方案，由于接入网设备发送给终端的节能指示用于指示根据终端发送的节能需求信息进行节能，因而该节能方式是符合终端的要求的，因此不会影响终端的正常业务，并且提升了节能的效果。
在一种可能的实现方式中，终端确定终端的下行调度时序，则终端需要的时频资源的信息包括终端的下行调度时序，终端的下行调度时序是指PDCCH调度信息所在的时隙到该调度信息调度的数据所在的时隙之间的时隙数。基于该方案，终端确定终端的下行调度时序，并将终端的下行调度时序作为调度需求信息发送至接入网设备，进而接入网设备可以向终端配置下行调度时序，使得终端可以在下行调度时序指定的时间点开启接收机接收数据，将有助于终端节能电量。

具体实施方式
为了使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请作进一步地详细描述。方法实施例中的具体操作方法也可以应用于装置实施例或系统实施例中。其中，在本申请的描述中，除非另有说明，“多个”的含义是两个或两个以上。
本申请描述的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，并不构成对于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。
如图1所示，为本申请所适用的一种可能的网络架构示意图，包括至少一个终端10，该终端10通过无线接口与接入网设备20通信，为清楚起见，图中只示出一个接入网设备和一个终端。
终端是一种具有无线收发功能的设备，终端可以部署在陆地上，包括室内或室外、手持或车载；也可以部署在水面上(如轮船等)；还可以部署在空中(例如飞机、气球和卫星上等)。所述终端可以是手机(mobile phone)、平板电脑(pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端、增强现实(augmented reality，AR)终端、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端，以及还可以包括用户设备(user equipment，UE)等。
接入网设备，也可以称为无线接入网(radio access network，RAN)设备，是一种为终端提供无线通信功能的设备。接入网设备例如包括但不限于：5G中的下一代基站(g nodeB，gNB)、演进型节点B(evolved node B，eNB)、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(baseBand unit，BBU)、传输点(transmitting and receiving point，TRP)、发射点(transmitting point，TP)、移动交换中心等。
在小区中，接入网设备和终端可以通过空口资源进行数据传输。空口资源可以包括时域资源和频域资源，时域资源和频域资源还可以称为时频资源。频域资源可以位于设置的频率范围，频率范围还可以称为频带(band)或频段，频域资源的宽度可以称为带宽(bandwidth，BW)。
基于图1所示的系统架构，本申请提供一种终端的节能方法。如图2所示，为本申请提供的终端的节能方法。该方法包括以下步骤：
步骤201，终端向接入网设备发送节能需求信息。相应地，接入网设备可以接收到该节能需求信息。
该节能需求信息中包括终端需要的时频资源的信息。其中，终端需要的时频资源的信息可以包括终端的下行调度时序、终端需要的带宽或终端需要的上行符号数中的至少一个。
在一种实现方式中，终端可以确定终端的下行调度时序，这里的下行调度时序是指PDCCH调度信息所在的时隙到该调度信息调度的下行数据所在的时隙之间的时隙数。然后，将下行调度时序作为终端需要的时频资源的信息发送至接入网设备，也即将下行调度时序作为终端的节能需求信息发送至接入网设备。
作为一种实现方式，终端若确定当前没有低时延业务(如超高可靠与低延迟的通信(Ultra Reliable&Low Latency Communication，uRLLC)业务)，则确定终端的下行调度时序，并将下行调度时序作为终端需要的时频资源的信息发送至接入网设备。作为又一种实现方式，终端若确定终端的当前电量小于第一电量阈值，则确定终端的下行调度时序，并将下行调度时序作为终端需要的时频资源的信息发送至接入网设备。作为又一种实现方式，终端若确定终端当前没有低时延业务并且确定终端的当前电量小于第一电量阈值，则确定终端的下行调度时序，并将下行调度时序作为终端需要的时频资源的信息发送至接入网设备。 其中，终端可以通过判断当前业务的服务质量(Quality of Service，QoS)分类标识(QoS Class Identifier，QCI)，确定当前是否存在低时延业务。
在5G通信中，可以使用K0值来表示终端的下行调度时序，比如终端可以根据自己的需求计算下行调度时序。作为示例，下面给出一种K0值的计算方式：K0＝ceil((t1+t2)/symbol)，其中，ceil()函数表示向上取整，t1表示终端解析盲检PDCCH的处理时间，t2表示开启接收机的过程所需要的时间，例如t2是开始开启接收机到完成开启接收机所需要的时间,symbol表示一个子帧中的符号数(例如可以取值为14)。一般情况下，K0值越大，则终端的业务处理时延越高；反之，K0值越小，则终端的业务处理时延越低。因此，当终端有低时延业务时，可以不开启K0，即K0设置为0，而当终端确定当前没有低时延业务时，可以开启K0，比如计算得到的K0可以为1、或2、或3等。
基于该方案，终端确定终端的下行调度时序，并将终端的下行调度时序作为调度需求信息中的终端需要的时频资源的信息发送至接入网设备，进而接入网设备可以向终端配置下行调度时序，使得终端可以在下行调度时序指定的时间点开启接收机接收数据，将有助于终端节能电量，能够避免终端在接收到PDCCH调度信息后，需要一直开启接收机并通过接收机接收物理下行共享信道(Physical Downlink Shared CHannel,PDSCH)数据而带来的电量耗费。
进一步的，终端在确定终端的下行调度时序之后，若确定终端的当前电量小于第二电量阈值，则还可以根据终端的当前电量，将终端的下行调度时序增加第一步长，得到更新后的下行调度时序，然后将更新后的终端的下行调度时序作为节能需求信息发送至接入网设备。即终端发送至接入网设备的下行调度时序是可以根据终端的当前电量进行调节的。
比如，作为一种实现方式，可以将[0，第二电量阈值]划分为N段，N为预设的大于的整数，每段对应的第一步长不同。下面结合具体示例进行说明。比如第二电量阈值为30％，N预设为3，则可以划分：
第一段：(0，10％],对应的第一步长为3。
第二段：(10％，20％],对应的第一步长为2。
第三段：(20％，30％),对应的第一步长为1。
比如，终端当前电量为25％，属于第三段，则第一步长为1，因此将计算得到的下行调度时序增加1。再比如，终端当前的电量为15％，属于第二段，则第一步长为2，因此将计算得到的下行调度时序增加2等等。
需要说明的是，上述仅作为示例，实际应用中还可以有其他的设定第一步长的方式，本申请不做限定。
一般地，当前电量值越低，表明越需要节能，因此将计算得到的K0值适当增大，以提高时延，从而达到节能的目的。因此该方案中，若更新了K0值，则可以将更新后的K0值作为节能需求信息发送至接入网设备。
在又一种可能的实现方式中，终端可以确定终端需要的带宽，将终端需要的带宽作为节能需求信息发送至接入网设备。
在又一种可能的实现方式中，当终端确定终端实际分配的带宽与终端需要的带宽的差值大于带宽差值阈值时，则终端需要的时频资源的信息包括终端需要的带宽，并将终端需要的带宽作为节能需求信息发送至接入网设备。其中，带宽差值阈值是可以根据终端的节能需求配置的，比如终端的当前电量越少，则带宽差值阈值可以配置地越小，反之，终端 的当前电量越多，则带宽差值阈值可以配置地越大。
比如，带宽差值阈值为30RB，终端实际分配的带宽为200RB，而终端实际需要的带宽为50RB，由于终端实际分配的带宽(200RB)与终端需要的带宽(50RB)的差值为150RB，其大于带宽差值阈值30RB，因此终端确定需要减少终端的带宽，以实现节能目的。因此终端将计算得到的终端需要的带宽作为节能需求信息发送至接入网设备。其中，终端实际分配的带宽与终端需要的带宽的差值大于带宽差值阈值的含义为：终端实际分配的带宽过大，终端不需要使用如此多的带宽，因此可以适当地减小带宽。
作为示例，下面给出一种终端需要的带宽的计算方式。终端需要的带宽＝(beta*平均数据量)/(k*R*Qm*v)。其中，beta为系数，用于调整计算的资源块(resource block，RB)数，平均数据量(也称为平均业务量)是统计一段时间的终端数据量得到的，k为一个时隙中的一个RB的有效资源单元(resource element，RE)数，比如，k可以等于156，即12*13＝156(12为每个符号中的RE数目，13为每个时隙中有效的符号数)，R为码率，Qm为调制阶数，v为平均的Rank数，其中，R和Qm可以根据统计得到的平均调制与编码策略(Modulation and Coding Scheme，MCS)查表得到。比如，可以获取一段时间内调度的调度信息里的一个或多个MCS，然后根据获取的一个或多个MCS计算得到平均MCS，然后查表，获取该平均MCS对应的R和Qm。需要说明的是，在具体实现中，可以计算终端需要的上行带宽，也可以计算终端需要的下行带宽，或者还可以计算终端需要的上行带宽和下行带宽。
基于该方案，当终端当前实际分配的带宽与终端需求的带宽的差值较大，比如大于带宽差值阈值时，则终端可以请求接入网设备减少带宽，因此将终端需要的带宽作为节能需求信息发送至接入网设备，使得接入网设备为终端配置其需要的带宽值。
进一步的，终端在确定终端需要的带宽之后，若确定终端的当前电量小于第三电量阈值，则还可以根据终端的当前电量，将终端需要的带宽减少第二步长得到更新后的终端需要的带宽，然后将更新后的终端需要的带宽作为终端需要的时频资源的信息发送至接入网设备。即终端发送至接入网设备的终端需要的带宽是可以根据终端的当前电量进行调节的。
比如，作为一种实现方式，可以将[0，第三电量阈值]划分为M段，M为预设的大于1的整数，每段对应的第二步长不同。下面结合具体示例进行说明。比如第三电量阈值为20％，M预设为4，则可以划分：
第一段：(0，5％],对应的第二步长为4*k(RB)。
第二段：(5％，10％],对应的第二步长为3*k(RB)。
第三段：(10％，15％],对应的第二步长为2*k(RB)。
第四段：(15％，20％),对应的第二步长为1*k(RB)。
其中，k＝(终端需要的带宽-终端最低带宽)/M。比如，终端需要的带宽为50RB，终端最低带宽为10RB，M＝4，则k＝10。因此：
第一段：(0，5％],对应的第二步长为40RB。
第二段：(5％，10％],对应的第二步长为30RB。
第三段：(10％，15％],对应的第二步长为20RB。
第四段：(15％，20％),对应的第二步长为10RB。
比如，终端当前电量为18％，属于第四段，因此将计算得到的终端需要的带宽减少10RB，得到的更新后的终端需要的带宽为40RB。再比如，终端当前的电量为12％，属于第三段， 因此将计算得到的终端需要的带宽减少20RB，得到的更新后的终端需要的带宽为30RB等等。
需要说明的是，上述仅作为示例，实际应用中还可以有其他的设定第一步长的方式，本申请不做限定。
一般地，当前电量值越低，表明越需要节能，因此将计算得到的终端需要的带宽适当降低，以减少分配的带宽，从而达到节能的目的。因此该方案中，若更新了终端需要的带宽，则将更新后的终端需要的带宽作为节能需求信息发送至接入网设备。
在又一种可能的实现方式中，终端可以确定终端需要的上行符号数，将终端需要的上行符号数作为节能需求信息发送至接入网设备。
在又一种可能的实现方式中，当终端确定终端实际分配的上行符号数与终端需要的上行符号数的差值大于符号数差值阈值时，则终端需要的时频资源的信息包括终端需要的上行符号数，并将终端需要的上行符号数作为节能需求信息发送至接入网设备。
比如，符号数差值阈值为2，终端实际分配的上行符号数为12，而终端实际需要的上行符号数为8，由于终端实际分配的上行符号数(12)与终端需要的上行符号数(8)的差值为4，其大于符号数差值阈值2，因此终端确定需要减少终端的上行符号数，以实现节能目的。因此终端将计算得到的终端需要的上行符号数作为节能需求信息发送至接入网设备。其中，终端实际分配的上行符号数与终端需要的上行符号数的差值大于符号数差值阈值的含义为：终端实际分配的上行符号数过多，终端不需要使用如此多的上行符号数，因此可以适当地减少上行符号数。
作为示例，下面给出一种终端需要的上行符号数的计算方式。终端需要的上行符号数＝RB0*symbol/RBbwp。其中，RB0为用户实际调度的RB数，symbol为用户实际调度的符号数(例如可以是一个时隙包括的符号的个数，例如为14)，RBbwp为当前使用的带宽部分(bandwidth part，BWP)。其中，这里的RB0可以是上述终端实际分配的带宽，这里的RBbwp可以是上述终端需要的带宽，具体计算方式可以参考前述描述，这里不再赘述。
基于该方案，当终端当前实际分配的上行符号数与终端需求的上行符号数的差值较大，比如大于符号数差值阈值时，则终端可以请求接入网设备减少上行符号数，因此将终端需要的上行符号数作为节能需求信息发送至接入网设备，使得接入网设备为终端配置其需要的上行符号数。
进一步的，终端在确定终端需要的上行符号数之后，若确定终端的当前电量小于第四电量阈值，则还可以根据终端的当前电量，将终端需要的上行符号数减少第三步长得到更新后的终端需要的上行符号数，然后将更新后的终端需要的上行符号数作为节能需求信息发送至接入网设备。即终端发送至接入网设备的终端需要的上行符号数是可以根据终端的当前电量进行调节的。
比如，作为一种实现方式，可以将[0，第四电量阈值]划分为L段，L为预设的大于1的整数，每段对应的第三步长不同。下面结合具体示例进行说明。比如第四电量阈值为40％，L预设为4，则可以划分：
第一段：(0，10％],对应的第三步长为4*t。
第二段：(10％，20％],对应的第三步长为3*t。
第三段：(20％，30％],对应的第三步长为2*t。
第四段：(30％，40％),对应的第三步长为1*t。
其中，t＝(终端需要的上行符号数-最少上行符号数)/L。比如，最少上行符号数为4，终端需要的上行符号数为8，L＝4，则t＝1。因此：
第一段：(0，10％],对应的第三步长为4。
第二段：(10％，20％],对应的第三步长为3。
第三段：(20％，30％],对应的第三步长为2。
第四段：(30％，40％),对应的第三步长为1。
比如，终端当前电量为18％，属于第二段，因此将计算得到的终端需要的上行符号数减少3，得到的更新后的终端需要的上行符号数为5。再比如，终端当前的电量为32％，属于第四段，因此将计算得到的终端需要的上行符号数减少1，得到的更新后的终端需要的上行符号数为7等等。
需要说明的是，上述仅作为示例，实际应用中还可以有其他的设定第一步长的方式，本申请不做限定。
一般地，当前电量值越低，表明越需要节能，因此将计算得到的终端需要的上行符号数适当降低，以减少分配的上行符号数，从而达到节能的目的。因此该方案中，若更新了终端需要的上行符号数，则将更新后的终端需要的上行符号数作为节能需求信息发送至接入网设备。即终端发送至接入网设备的终端需要的上行符号数是可以根据终端的当前电量进行调节的。
作为一种实现方式，上述调整终端的下行调度时序、调整终端需要的带宽、调整终端的上行符号数的实现方式还可以相结合使用，以得到终端发送至接入网设备的节能需求信息。
作为一种实现方式，上述第一电量阈值、第二电量阈值、第三电量阈值、第四电量阈值可以部分相同、或者全部不同、或者全部相同，本申请对此不做限定，可根据需要设定。
作为一种实现方式，上述任一实施例中，终端可以通过媒体接入控制(media access control，MAC)控制单元(Control Element，CE)、或者终端在接入过程中通过MSG3、或者调度请求(Scheduling Request，SR)、或者Preamble的方式向接入网设备发送终端的节能需求信息。
步骤202，接入网设备向终端发送节能指示。相应地，终端可以接收到该节能指示。
比如，该节能指示可以为RRC重配置消息。
作为一种实现方式，节能指示中可以包括终端需要的时频资源的信息，比如可以包括终端的下行调度时序，和/或，终端需要的带宽，和/或，终端需要的上行符号数。这里的节能指示中包括的终端需要的时频资源的信息即为终端向接入网设备发送的终端需要的时频资源的信息。
作为又一种实现方式，该节能指示中也可以不包括终端需要的时频资源的信息，该节能指示用于指示终端根据本地存储的终端需要的时频资源的信息进行节能。
在一种实现方式中，若接入网设备接收到的终端需要的时频资源的信息包括下行调度时序，则接入网设备接收到下行调度时序之后，更新下行调度时序的配置，然后可以将下行调度时序通过RRC配置消息配置给终端。并且，接入网设备在有数据调度时，按照终端发送的下行调度时序的配置进行调度。终端在接收到下行调度信息之后，立即关闭接收机，然后在下行调度时序对应的PDSCH位置上开启接收机，接收下行数据。
在一种实现方式中，若接入网设备接收到的终端需要的时频资源的信息包括终端需要 的带宽，则接入网设备接收到终端需要的带宽之后，将其转换为BWP配置，然后可以通过RRC配置消息下发给终端，以及通过RRC或下行控制信息(Downlink control information，DCI)激活所需的BWP。并且，终端在激活的BWP上进行数据收发。
在一种实现方式中，若接入网设备接收到的终端需要的时频资源的信息包括终端需要的上行符号，则接入网设备接收到终端需要的上行符号之后，更新上行符号配置，然后可以通过RRC配置消息配置给终端。接入网设备在后续的上行调度时，使用新的上行符号调度终端。
步骤203，终端根据节能需求信息进行节能。
即终端根据终端的下行调度时序、终端需要的带宽或终端需要的上行符号数中的至少一个进行配置，从而实现节能的目的。
通过上述步骤201-步骤203，由于接入网设备发送给终端的节能指示用于指示终端根据终端发送的节能需求信息进行节能，因而该节能方式是符合终端的要求的，因此不会影响终端的正常业务，并且提升了节能的效果，最大限度降低了终端的能耗。
