Description

终端的省电方法、省电装置、信息的发送方法及装置、存储介质和电子装置
本申请要求在2019年08月15日提交中国专利局、申请号为201910755353.5的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本公开涉及通信领域，例如涉及一种终端的省电方法、省电装置、信息的发送方法及装置、存储介质和电子装置。
背景技术
在多载波无线通信系统中，若基站为两个或多个载波配置自调度，则UE需要在所有配置自调度的载波上执行物理下行控制信道的监听(Physical Downlink Control Channel monitoring，PDCCH monitoring)以及信道测量，以备随时进行数据接收/发送。
在没有业务传输或业务量稀疏情况下，辅小区(Secondary Cell，SCell)上持续密集的PDCCH监听而没有数据调度的情况(即，PDCCH-Only)将会产生很多不必要的功耗。相关技术中的协议中，可通过媒体接入控制的控制元素(Media Access Control Control Element，MAC CE)指示SCell的激活或者去激活来降低终端的功耗，其中，UE在去激活的SCell上不进行PDCCH monitoring、信道测量以及数据接收等操作。
例如，相关技术中，5G新空口(NR，New Radio Access Technology)通信系统中，SCell具有激活态和去激活态两种状态，如果配置了一个SCell或多个SCells，则UE可以通过接收基站发送的SCell Activation/Deactivation MAC CE来实现对配置的SCells的激活或去激活，且基站还可以给每一个激活的SCell(除了配置有物理上行控制信道(Physical Uplink Control Channel，PUCCH)的SCell)配置一个sCellDeactivationTimer，当该sCellDeactivationTimer过期时，该Timer所关联的SCell去激活。
通过MAC CE进行SCell的激活/去激活会带来较大的时延问题，且频繁的激活/去激活又会带来大量不必要的功耗，使用该方案并不能达到很好地降低终端功耗的效果。

根据本发明的又一个实施例，还提供了一种信息的发送装置，包括：第一发送模块，用于向终端发送第一省电指示信息，其中，所述第一省电指示信息用于指示所述终端将当前被激活的第一载波切换至省电的状态。

以下结合具体场景对本发明实施例进行解释说明。
不连续接收(DRX；Discontinuous Receiving)是指UE不用连续地接收基站发射的信号或/和信道。基站可以给各个UE配置DRX周期和偏移。在一个DRX周期内，UE需在DRX活动时间(DRX-ON)接收基站发射的信号或/和信道，在DRX不活动时间(DRX-OFF)则不需要接收。
在载波聚合(CA；Carrier Aggregation)场景下，一个UE只有一个MAC实体，因此，所有的Cell共用一个DRX配置。在双连接(DC；Dual Connection)场景下，主小区组(MCG，Master Cell Group)和辅小区组(SCG，Secondary Cell Group)分别对应一个MAC实体，每个Cell组共用一个DRX配置。即，当一个激活的Cell上有数据调度，且激活drx-InactivityTimer时，同一Cell组内所有激活的Cell上PDCCH监听时间都将延长。
需要说明的是，以下实施例中的“休眠状态”、“省电状态”、“非省电状态”、“正常状态”只是列举了几种不同的状态类型，这几种状态各有特性，所对应的功耗各有区别，在不同的情形下，均可以理解为是上述的实施例中的“省电的状态”。例如，当载波上无数据传输时，载波从当前的“非省电状态”切换至“省电状态”，或者，载波从当前的“省电状态”切换至“休眠状态”均可以理解为是载波从当前状态切换到了“省电的状态”；又如，当载波上有数据传输时，载波从当前的“省电状态”切换至“非省电状态”，或者，载波从当前的“休眠状态”切换至“省电状态”均可以理解为是载波从当前状态切换到了“省电的状态”；例如，在有数据调度需求时，使用数据传输速率较大的“非省电状态”可以快速调度数据，相比于使用“省电状态”进行更长时间的数据调度而言，功耗反而会更少。
本发明实施例提供的省电方法可以是：接收省电信号/信道；对服务小区(即载波)进行操作。对服务小区进行操作可以是对服务小区上的带宽部分(Bandwidth part，BWP)进行BWP切换或者进行BWP状态转换。
在一个实施方式中，当UE成功检测到省电信号/信道时，UE从当前BWP切换到非省电BWP上。
在一个实施方式中，该当前BWP为省电BWP；该省电BWP具有一定的省电特性；该非省电BWP为配置了跨时隙调度的BWP；该省电BWP为具有最大PDCCH监视周期的BWP。
在一个实施方式中，该当前BWP为非省电BWP；该非省电BWP为配置了同时隙调度的BWP；该非省电BWP为具有最小PDCCH监视周期的BWP。在一个实施方式中，该省电信号/信道是UE在PCell上检测到的。该省电信号/信道还可以是UE在SCell上检测到的。
在一个实施方式中，UE根据省电信号/信道来进行BWP切换；UE根据省电信号/信道来进行BWP状态转换。
在一个实施方式中，SCell上的BWP可以具有多种状态；例如Active state、Inactive state和dormant state；其中，BWP dormant state可以实现dormancy behavior。在一个实施方式中，BWP状态切换时延为n个symbols；其中，n与子载波间隔相关。
在一个实施方式中，基站可以与指定的载波具有相同的操作；该相同的操作可以是：当一个服务小区从当前激活的BWP状态从BWP dormant state切换至BWP激活状态时，另一个服务小区也从BWP dormant state切换至BWP激活状态。
在一个实施方式中，根据省电信号/信道来在服务小区上进行搜索空间的监视。
在一个实施方式中，BWP切换包括：UE对当前激活BWP为dormant BWP的指定载波执行BWP切换操作；所述BWP切换操作包括从dormant BWP切换至省电BWP。所述BWP切换操作包括从dormant BWP切换至正常BWP。所述BWP切换还可以包括：UE从dormant BWP切换至省电BWP时，需要执行预窗操作；UE从dormant BWP切换至省电BWP时，需要报告CSI；UE从dormant BWP切换至正常BWP时，需要执行预窗操作；UE从dormant BWP切换至正常BWP时，需要报告CSI；所述正常BWP指可正常进行PDCCH monitoring和数据接收的BWP。
在一个实施方式中，所述BWP切换包括：UE从省电BWP切换至正常BWP时，需要执行预窗操作；UE从省电BWP切换至正常BWP时，需要报告CSI。
在一个实施方式中，当UE成功检测到省电信号/信道时，UE从BWP dormant state切换至BWP active state。
在一个实施方式中，当UE从dormant state切换至active state时，需要执行预窗操作；当UE从dormant state切换至active state时，需要报告CSI。
在一个实施方式中，UE根据省电信号/信道的比特指示来进行操作；所述操作包括对服务小区的操作和/或对BWP的操作；例如SCell的状态变更；BWP切换；SCell是否进行正常的PDCCH monitoring。
省电信号/信道中可以设置n个比特，用于触发UE在辅载波上的操作，例如可以指示SCell在接下来到达的DRX-ON duration切换至/保持dormancy behavior；或者，SCell在接下来到达的DRX-ON duration正常进行PDCCH monitoring准备进行数据接收；或者，SCell跳过即将到来的DRX-ON duration。
在一个实施方式中，省电信号/信道重用载波指示比特域来指示UE的操作；例如，可以指示UE对SCell在接下来到达的DRX-ON duration切换至/保持dormancy behavior；该dormancy behavior可通过将BWP切换至dormant BWP实现；该dormancy behavior可通过将BWP从active state切换至dormant state实现。
在一个实施方式中，UE根据定时器或特定的时间长度来对服务小区进行操作；或者，UE根据定时器或特定的时间长度来对SCell进行操作；或者，UE根据定时器或特定的时间长度来对BWP进行操作。
在一个实施方式中，UE对于在DRX-ON duration(或DRX活动时间)的一段时间内未得到调度的SCell执行省电操作；例如，可以是从当前激活的BWP切换到default BWP；或者，从当前激活的BWP切换到initial BWP；或者，从当前激活的BWP切换到dormant BWP；从当前的BWP active state切换到BWP dormant state。
在一个实施方式中，两个或多个载波上的BWP之间可以具有绑定关系。该绑定关系包括：一个服务小区上的BWP切换会引起部分服务小区上BWP切换；或者，一个服务小区上的特定BWP切换会引起部分服务小区上特定BWP切换；例如，当一个载波切换到具有最大传输速率的BWP时，另一个载波也切换到具有最大传输速率的BWP；又如，当一个载波切换到低功耗BWP时，另一个载波也切换到低功耗BWP；需要说明的是，当一个载波切换到具有最大传输速率的BWP时，另一个载波可以不切换BWP，但重新激活bwp-InactivityTimer；或者，当一个载波切换到低功耗BWP时，另一个载波可以不切换BWP，但重新激活bwp-InactivityTimer。
在一个实施方式中，UE根据定时器来进行BWP的状态转换；例如，通过定时器来使得BWP active state、BWP dormant state和default/initial BWP之间相互切换。例如，当bwpDormancyTimer到期时，当前激活BWP从active state切换至dormant state。
在一个实施方式中，UE根据省电信号/信道来监视搜索空间。例如，接收到省电信号/信道之后，UE仅在共享搜索空间上执行PDCCH monitoring；或者，接收到省电信号/信道之后，UE在辅载波上执行自调度的搜索空间监视；或者，接收到省电信号/信道之后，UE在辅载波上执行PDCCH monitoring；或者，接 收到省电信号/信道之后，UE在辅载波上执行自调度的PDCCH monitoring。
在一个实施方式中，UE根据省电信号/信道的比特域指示来监视搜索空间；UE根据MAC CE或RRC信令或Timer来监视搜索空间。该搜索空间的监视可以是：接收到省电信号/信道的比特域之后，UE只在共享空间上搜索PDCCH；或者，接收到MAC CE之后，UE只在共享空间上搜索PDCCH；或者，接收到RRC信令之后，UE只在共享空间上搜索PDCCH；或者，Timer过期之后，UE只在共享空间上搜索PDCCH。
可选实施方式1
该实施例主要描述的是，用户设备(User Equipment，简称UE)如何根据基站发送的省电信号/信道来切换BWP。所述省电信号/信道可以是具有唤醒功能的信号/信道，如称为WUS。WUS，即Wake Up Signal的简称。
基站侧：
基站为UE配置DRX。
基站给UE的主载波(PCell，Primary Cell；主小区)发省电信号/信道。所述省电信号/信道可以是承载在PDCCH上的具有唤醒功能的信号，如WUS-PDCCH。该唤醒信号出现在不连续接收的醒着时间(DRX-ON)之前，如果UE检测到WUS-PDCCH，则UE在下一个DRX-ON唤醒，执行PDCCH monitoring，准备接收或发送数据；如果未成功检测到，则UE跳过下一个(或多个)DRX-ON，保持DRX-OFF状态。
基站为PCell配置省电BWP(指定某一bwp-Id对应的BWP为省电BWP)。所述省电BWP具有某一种或多种省电特性。可选的，该省电BWP具有小的带宽(在PCell上所配BWP中带宽最小)。可选的，该省电BWP具有少的MIMO层数(在PCell上所配BWP中MIMO层数最少)。可选的，该省电BWP具有大的PDCCH monitoring周期(在PCell上所配BWP中PDCCH monitoring周期最大)。可选的，该省电BWP配置cross-slot scheduling(体现在相关参数K0，K1，K2和非周期信道状态信息参考信号(Aperiodic Channel State Information Reference Signal，A-CSI-RS)triggering offset设置为大于0的数)。
终端侧：
UE在PCell上的outside active time接收由基站发送的省电信号/信道。当UE成功检测到省电信号/信道时，UE将进行一定的操作。所述操作包括：接收基站发射的参考信号(如，信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)、发送CSI报告、发送一定的信号/信道、进行BWP 切换等。主要如下。
若PCell上成功检测到省电信号/信道，则，可选的，UE在PCell上即将到来的DRX-ON之前或在DRX-ON早期的一段时间执行预窗操作(包括，UE接收基站发射的CSI-RS、UE发送CSI报告、UE发射探测参考信号(Sounding Reference Signal，SRS))。在所述预窗这一段时间内，用户设备(UE)需要做好接收基站发射的数据或向基站发射数据的准备(即，UE准备接收PDSCH，发送PUSCH)。

可选实施方式6
该实施例主要描述对各个服务小区上的载波进行BWP捆绑：一个服务小区上的BWP切换会引起BWP切换或保持当前BWP，例如，一个服务小区上的BWP切换或者保持会引起与该BWP具有绑定关系的BWP的同步切换或者保持。
基站为UE配置多个载波。
基站为指定载波建立绑定关系。可选的，所述指定载波为主载波和所有辅载波。可选的，所述指定载波为主载波和部分辅载波。所述绑定关系表现为：SpCell(包含PCell和PSCell)上切换BWP时，隐式的指示具有绑定关系的辅载波也切换BWP。
基站按照省电效果对各个载波上所配置的BWP进行排序，每个BWP对应一个省电级别。如：一级为最省电级别，二级次之，以此类推。可选的，BWP的省电级别判定方法为：根据带宽和MIMO层数判断，具有最小带宽和最少MIMO层数的BWP省电级别最高。
SpCell上BWP切换时，隐式的指示SCells上的BWP切换，且切换的目标BWP从BWP候选集中选择。BWP的候选集生成方法为：SCell上的BWP省电级别不低于PCell上BWP的省电级别。需要说明的是，可以认为数据会优先在PCell上传输，当PCell在省电BWP时，SCell也应该在省电BWP上。
UE根据省电级别来进行BWP切换或保持当前的BWP。可选的，候选BWP集和切换的目标BWP的选择方法为：BWP候选集中的BWP个数不超过两个，可以避免SCell始终处于最省电BWP上。且选择符合候选集生成条件的省电级别最低的两个BWP组成BWP候选集。优先选择省电级别高的BWP为目标BWP。且附加条件，SpCell处于省电级别最低的BWP时，SCell不得处于省电级别最高的BWP上。
举例如下：
当前UE共有三个激活的载波，分别为PCell、SCell1和SCell2。其中，PCell 上共有3个BWP，按照省电级别从高到低分别为BWP0，BWP1，BWP2。SCell1上有四个BWP，按照省电级别从高到低分别为BWP0，BWP1，BWP2，BWP3。SCell2上有两个BWP，按照省电级别从高到低分别为BWP0，BWP1。
当PCell上切换到具有最高省电级别的BWP0时，对应SCell1和SCell2上的BWP候选集都只包含一个元素{BWP0}。因此SCell1和SCell2均切换到具有最高省电级别的BWP0上。如果SCell上激活的BWP本身就是BWP0，则重新激活bwp-InactivityTimer。当PCell上激活BWP由BWP0切换到BWP2时，SCell1上的BWP候选集为{BWP1，BWP2}，SCell2上的BWP候选集为{BWP0，BWP1}。按照“优先选择省电级别高的BWP，且PCell处于省电级别最低的BWP时，SCell不得处于省电级别最高的BWP”原则，SCell1切换至BWP1，SCell2切换至BWP1。当PCell上激活BWP由BWP2切换到BWP1时，对应SCell1上和SCell2上的BWP候选集均为{BWP0，BWP1}，SCell上优先选择省电级别高的BWP，因此SCell1上和SCell2均激活BWP0。
UE可根据SpCell的DCI来进行BWP切换或保持当前的BWP。可选的，候选BWP集和目标BWP的选择方法为：BWP候选集元素为所有符合候选集生成条件的BWP。优先选择相同省电级别的BWP为目标BWP。且当SCell上激活的BWP本身处于候选集的时候，不进行BWP切换。可以减少BWP切换次数，避免频繁的切换造成的时延和不必要的功耗。当SCell上没有相同省电级别的BWP时，优先切换到具有相邻省电级别的BWP上。
举例如下：
当前UE共有三个激活的载波，分别为PCell、SCell1和SCell2。其中，PCell上共有3个BWP，按照省电级别从高到低分别为BWP0，BWP1，BWP2。SCell1上有四个BWP，按照省电级别从高到低分别为BWP0，BWP1，BWP2，BWP3。SCell2上有两个BWP，按照省电级别从高到低分别为BWP0，BWP1。
当PCell上切换到具有最高省电级别的BWP0时，对应SCell1和SCell2上的BWP候选集都只包含一个元素{BWP0}。因此SCell1和SCell2均切换到具有最高省电级别的BWP0上。当PCell切换到BWP1时，对应SCell1上的BWP候选集均为{BWP0，BWP1}。按照优先切换原则，SCell1和SCell2均切换至BWP1。当PCell切换到BWP2时，对应SCell1上的BWP候选集为{BWP0，BWP1，BWP2}，SCell2上的BWP候选集为{BWP0，BWP1}，按照优先切换原则，SCell1和SCell2均保持在BWP1不做切换，并激活bwp-InactivityTimer。
如果SpCell的PDCCH指示了一个切换BWP的DCI，使得SCell进行BWP切换，且在切换后的BWP上执行PDCCH monitoring，则SCell上开始monitor PDCCH的时间与PCell上接收到指示切换的DCI的时间有一个时间差(offset)。 UE在这个时间差内完成两个动作：一是完成PCell的PDCCH decoding；二是完成SCell上的BWP switching。可选的，UE在该offset期间不执行PDCCH monitoring。可选的，UE在该offset期间不做PDCCH buffer。

SpCell上BWP切换时，隐式的指示SCell上的BWP切换，且切换BWP从BWP候选集中选择。所述BWP的候选集选择方法为：SCell上的BWP数据传输速率级别不高于SpCell上BWP的数据传输速率级别。
UE根据服务小区的BWP的数据传输速率级别来进行BWP选择。可选的，候选BWP集和切换的目标BWP的选择方法为：限制BWP候选集BWP个数不超过两个，可以避免SCell始终处于最省电BWP上。
且选择符合条件的数据传输速率最高的两个BWP组成BWP候选集。切换时，优先选择数据传输速率级别低的BWP为目标BWP。且，PCell处于数据传输速率级别最高的BWP时，SCell不得处于数据传输速率级别最低的BWP上。
可选的，候选BWP集和切换的目标BWP的选择方法为：BWP候选集元素为所有符合候选集生成条件的BWP。优先选择相同数据传输速率级别的BWP为目标BWP。当SCell上激活的BWP本身处于候选集的时候，可以不进行BWP切换(即，保持当前的BWP)。减少BWP切换次数，避免频繁的切换造成的时延和不必要的功耗。
当SCell上没有相同数据传输速率级别的BWP时，优先切换到具有相邻数据传输速率级别的BWP上。
