Description

省电信号的参数动态变更方法、装置、终端和介质 技术领域
本公开涉及无线通信领域，特别涉及一种省电信号的参数动态变更方法、装置、终端和介质。
背景技术
第三代合作伙伴项目(Third Generation Partnership Project，3GPP)标准协议引入了非连续接收机制(Discontinuous Reception，DRX)的节能策略，DRX的基本机制是为处于无线资源控制(Radio Resource Control，RRC)连接态的终端配置一个DRX周期，实现节省终端电量的目的。DRX周期由激活期和休眠期组成。
在激活期内，终端监听并接收物理下行控制信道(Physical Downlink Control CHannel，PDCCH)；在休眠期内，终端不监听PDCCH以减少功耗。由于终端在周期性出现的激活期内仅是机会性得到调度，因此存在多数激活期内的PDCCH检测并没有检测到数据调度的情况，导致检测功率浪费。为了解决这个问题，引入了省电信号(Wake Up Signaling，WUS),当基站判断需要在激活期内调度终端时，则先向终端发射省电信号。终端检测到省电信号，意味着需要在接下来的DRX激活期对PDCCH进行监听；终端没有检测到省电信号，意味着需要在接下来的DRX激活期跳过对PDCCH的监听。
载波聚合场景下，辅载波随数据传输的需要进行激活或去激活操作，终端数据调度的情况也在变化。对于如何在载波聚合场景下，配置省电信号的参数，优化对PDCCH的监听密度的问题，相关技术还没有合理的解决方案。

具体实施方式
为使本公开的目的、技术方案和优点更加清楚，下面将结合附图对本公开实施方式作进一步地详细描述。
图1示出了本公开一个示意性实施例提供的通信系统的框图。如图1所示，该通信系统可以包括：接入网12和终端13。
接入网12中包括若干个接入网设备120。接入网设备120与核心网设备110之间通过某种接口技术互相通信，例如LTE系统中的S1接口，5G NR系统中的NG接口。接入网设备120可以是基站，所述基站是一种部署在接入网中用以为终端提供无线通信功能的装置。所述基站可以包括各种形式的宏基站，微基站，中继站，接入点等等。在采用不同的无线接入技术的系统中，具备基站功能的设备的名称可能会有所不同，例如在LTE系统中，称为eNodeB或者eNB；在5G NR系统中，称为gNodeB或者gNB。随着通信技术的演进，“基站”这一名称可能描述，会变化。
终端13可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其他处理设备，以及各种形式的用户设备，移动台(Mobile Station，MS)等等。接入网设备120与终端13之间通过某种空口技术互相通信，例如Uu接口。
以下对本申请实施例涉及的若干个技术术语进行简介：
非连续接收(Discontinuous Reception，DRX)：DRX可以让终端周期性的在某些时候进入休眠期，不去监听PDCCH调度信息(或称PDCCH子帧)。而在终端需要监听PDCCH调度信息的时候，则从休眠期中唤醒(wake up)，这样就可以使终端达到省电的目的。
DRX的基本机制是为处于RRC_CONNECTED态的终端配置一个DRX周期(DRX cycle)。DRX周期由“激活期(On Duration)”和“休眠期(Opportunity for DRX)”组成：在“激活期”的时间内，终端监听并接收PDCCH调度信息；在“休眠期”时间内，终端不接收下行信道的数据以节省功耗。从图2可以看出，在时域上，时间被划分成一个个连续的DRX周期(Cycle)。当终端在“激活期”期间收到一个调度消息时，终端会启动一个DRX非活跃态定时器(DRX-Inactivity Timer)并在该期间的每一个子帧监听PDCCH调度信息；如果 DRX-inactivity Timer正在运行，那么即便原本配置的On Duration时间已经结束，终端仍然需要继续监听下行的PDCCH子帧，直到DRX Inactivity Timer的超时。
一个DRX周期等于终端的唤醒时间和休眠时间的总和，唤醒时间即为一个周期内的激活态的时长，休眠时间即为一个周期内的休眠期的时长。
省电信号：在5G以及LTE演进项目中，目前正讨论DRX的增强机制，例如网络虽然给终端配置了DRX机制，终端在周期性出现的on duration仅是机会性的得到调度，甚至在终端业务负荷很低的情况下终端仅仅有少数的DRX周期内会得到调度；对于采用DRX机制的寻呼消息而言，终端接收到寻呼消息的时机更少。因此，终端在配置了DRX机制后，仍然存在多数on duration内的PDCCH检测并没有检测到数据调度，如果终端在没有数据调度的时候盲检PDCCH，检测的功率浪费就被浪费掉了。因此针对目前的DRX机制，存在更进一步的优化空间。
目前一种解决方案是，如果基站判断需要在DRX on duration调度终端，则向终端发送省电信号，该省电信号用于唤醒终端，使得终端在DRX的on duration进行PDCCH检测；否则，如果基站判断不需要在DRX on duration调度终端，则可以向终端指示终端在DRX的on duration内不进行PDCCH检测。
另外在研究中发现，省电信号除了用于唤醒终端检测PDCCH，还可以用于指示终端唤醒时所使用的目标带宽部分(BandWidth Part，BWP)、所使用的PDCCH搜索空间的配置等信息。在本申请实施例中，省电信号的功能可以包括上述功能中的全部或一部分，也可以包括上述功能中未示出的功能，对此不加以限定。
载波聚合：载波聚合(Carrier Aggregation,CA)是将2个或更多的载波单元(Component Carrier,CC)聚合在一起以支持更大的传输带宽。如图3所示，CA技术可以将2～5个载波聚合在一起，实现最大100MHz的传输带宽，有效提高了上下行传输速率。
主小区(Primary Cell，PCell)是终端进行初始连接建立的小区，或进行RRC连接重建的小区，或是在小区切换过程中指定的主小区。PCell负责与终端之间的RRC通信。PCell对应的载波单元称为主载波(Primary Component Carrier，PCC)。
辅小区(Secondary Cell，SCell)是在RRC重配置时添加的，用于提供额外的无线资源，SCell与终端之间不存在任何RRC通信。SCell对应的载波单元 称为辅载波(Secondary Component Carrier，SCC)。
同一时刻只存在一个主载波,允许存在多个辅载波，比如3个辅载波。网络可以根据需要将暂不使用的辅载波设置为非激活态,降低终端功耗；也可以快速激活辅载波满足传输需要。终端的主载波不能被去激活；终端只能在激活的载波上进行数据传输,在去激活载波上只支持有限度的测量。
可以得知的是，当辅载波被激活时，往往是大量数据传输的时刻。此时，需要将对PDCCH的监听变得更加密集，提高数据的传输速率。
结合参考图4，在DRX前面配置省电信号存在四种情况，包括：
如图4中的(a)所示，去使能省电信号，在每一个DRX周期前面没有配置省电信号。在每一个DRX的激活期内，终端都监听PDCCH。
如图4中的(b)所示，在每一个DRX周期前面配置一个省电信号，省电信号和DRX的映射关系为1：1。若终端检测到省电信号，则在下一个DRX的激活期内监听PDCCH。若终端没有检测到省电信号，则跳过在下一个DRX的激活期内对PDCCH的监听。
如图4中的(c)所示，在每N个DRX周期前面配置一个省电信号,N为大于1的整数，省电信号和DRX的映射关系为1：N。若终端检测到省电信号，则在接下来的N个DRX的激活期内监听PDCCH。若终端没有检测到省电信号，则跳过在接下来的N个DRX的激活期内对PDCCH的监听。图4中的(c)中，N的值取2。
如图4中的(d)和图4中的(e)所示，若终端检测到省电信号，则在接下来的N1个DRX的激活期内监听并接收PDCCH，也即在检测到省电信号时，省电信号和DRX的映射关系为1：N 1。
若终端没有检测到省电信号，则跳过在接下来的N2个DRX的激活期内对PDCCH的监听，也即在未检测到省电信号时，省电信号和DRX的映射关系为1：N2。其中，N1和N2为整数，N1和N2的值不相等。
图4中的(d)中，N1的值取1，N2的值取3。图4中的(e)中，N1的值取2，N2的值取1。
图5示出了本公开一个示例性实施例提供的省电信号的参数动态变更方法的流程图，应用于载波聚合场景的UE中。该方法包括：
步骤501，确定载波所处的状态；
UE是支持省电信号的设备。
载波的状态分为激活和非激活两种状态。
在一个示例中，如果UE配置了一个主载波和至少一个辅载波，主载波总是处于激活状态，UE可通过MAC CE对所配置的辅载波进行激活与去激活操作。
对处于非激活状态的辅载波,UE不监听其PDCCH信道，不在该载波上行共享信道进行数据传输。
步骤502，根据载波所处的状态变更省电信号的模式参数；
PDCCH的监听密度是根据省电信号所映射的DRX周期的个数来确定的。
使能模式参数时，用N1表示监听到省电信号时一个省电信号所映射的DRX周期的个数，监听密度与N1的大小成正比。N1越大，监听密度越大；N1越小，监听密度越小。
使能模式参数时，用N2表示未监听到省电信号时一个省电信号所映射的DRX周期的个数，监听密度与N2的大小成反比。N2越大，监听密度越小；N2越小，监听密度越大。
PDCCH的监听密度变大包括以下几种情况中的至少一种：
去使能省电信号的模式参数、N1变大、N2变小，N1变大且N2变小。
PDCCH的监听密度变小包括以下几种情况中的至少一种：
使能省电信号的模式参数、N1变小、N2变大，N1变小且N2变大。
省电信号的模式参数变更包括以下几种情况中的至少一种：
一、去使能省电信号的模式参数变更为使能省电信号的模式参数。
示例的，图4中的(a)变更为图4中的(b)；或，图4中的(a)变更为图4中的(c)；或，图4中的(a)变更为图4中的(d)。
二、使能省电信号的模式参数变更为去使能省电信号的模式参数。
示例的，图4中的(b)变更为图4中的(a)；或，图4中的(c)变更为图4中的(a)；或，图4中的(d)变更为图4中的(a)。
三、省电信号的第一模式参数变更为第二模式参数。
示例的，图4中的(d)变更为图4中的(b)。当检测到省电信号时，都对下一个DRX进行PDCCH的监听。当未检测到省电信号时，图4中的(d)跳过接下来的3个DRX内的PDCCH的监听，图4中的(b)跳过下一个DRX内 的PDCCH的监听，监听密度变大。
四、省电信号的第二模式参数变更为第一模式参数。
示例的，图4中的(b)变更为图4中的(d)。当检测到省电信号时，都对下一个DRX进行PDCCH的监听。当未检测到省电信号时，图4中的(b)跳过下一个DRX内的PDCCH的监听，图4中的(d)跳过接下来的3个DRX内的PDCCH的监听，监听密度变小。
在基于图5的实施例中，
当第一个辅载波处于激活状态时，第一个辅载波的激活用于触发UE去使能省电信号的模式参数，或，将省电信号的第一模式参数变更为第二模式参数。
当至少T1个辅载波处于激活状态时，至少T1个辅载波的激活用于触发UE去使能省电信号的模式参数，或，将省电信号的第一模式参数变更为第二模式参数。
当全部辅载波处于非激活状态时，全部辅载波的非激活状态用于触发UE使能省电信号的模式参数，或，将省电信号的第二模式参数变更为第一模式参数。
当至少T2个辅载波处于非激活状态时，至少T2个辅载波的非激活状态用于触发UE使能省电信号的模式参数，或，将省电信号的第二模式参数变更为第一模式参数。
综上所述，本实施例提供的方法，在载波聚合的场景下，UE通过根据载波所处的状态动态的变更省电信号的参数，调整对PDCCH的监听密度，节省了UE用来监听的功率。
图6示出了本公开一个示例性实施例提供的省电信号的参数动态变更方法的流程图，应用于载波聚合场景的基站中。该方法包括：
步骤601，发送载波的状态，载波的状态用于触发用户设备UE根据载波所处的状态变更省电信号的模式参数；
在一个示例中，发送载波的状态，包括：发送MAC CE，MAC CE携带有载波的状态。
载波的状态分为激活和非激活两种状态。多载波系统中，UE同时在多个载波上工作时，需要同时监听多个载波上的调度信令，并同时在多个载波上反馈下行信道质量信息，大大增加了UE的能量消耗。因此，通过基站引入载波激活/去激活机制，可以快速改变传输带宽，适应业务需求，降低终端能量消耗。
在一个可选的示例中，MAC CE携带有指示，指示用于指示变更省电信号的模式参数。
在一个示例中，载波的状态包括：第一个辅载波处于激活状态；第一个辅载波的激活用于触发UE去使能省电信号的模式参数，或，将省电信号的第一模式参数变更为第二模式参数。
在一个示例中，载波的状态包括：至少T1个辅载波处于激活状态；至少T1个辅载波的激活用于触发UE去使能省电信号的模式参数，或，将省电信号的第一模式参数变更为第二模式参数。
其中，T1为大于1的整数。第一模式参数对应的PDCCH的监听密度小于所述第二模式参数对应的PDCCH的监听密度，PDCCH的监听密度是根据省电信号所映射的DRX周期的个数来确定的。
在一个可选的示例中，基站可以预先向UE发送第一RRC消息或第一系统消息；第一RRC消息或第一系统消息携带有T1的值。之后，基站再向UE发送MAC CE，指示载波所处的状态。
第一RRC消息或第一系统消息是指通知UE将对PDCCH的监听密度变大的RRC消息或系统消息。
在一个示例中，载波的状态包括：全部辅载波处于非激活状态；全部辅载波的非激活状态用于触发UE使能省电信号的模式参数，或，将省电信号的第二模式参数变更为第一模式参数；至少T2个辅载波处于非激活状态。
在一个示例中，载波的状态包括：至少T2个辅载波的非激活状态用于触发UE使能省电信号的模式参数，或，将省电信号的第二模式参数变更为第一模式参数。
其中，T2为大于1的整数。第一模式参数对应的PDCCH的监听密度小于所述第二模式参数对应的PDCCH的监听密度，PDCCH的监听密度是根据省电信号所映射的DRX周期的个数来确定的。
在一个可选的示例中，基站可以预先向UE发送第二RRC消息或第二系统消息；第二RRC消息或第二系统消息携带有T2的值。之后，基站再向UE发送MAC CE，指示载波所处的状态。
第二RRC消息或第二系统消息是指通知UE将对PDCCH的监听密度变小的RRC消息或系统消息。
综上所述，本实施例提供的方法，在载波聚合的场景下，基站通过发送载 波的状态通知UE变更省电信号的参数，调整UE对PDCCH的监听密度，节省了UE用来监听的功率。
结合参考图7，图7示出了本公开一个示例性实施例提供的省电信号的参数动态变更方法的流程图，应用于载波聚合场景中。图7中省电信号的模式参数变更情况是使能省电信号的模式参数变更为去使能省电信号的模式参数。该方法包括：
步骤701，UE使能省电信号的模式参数；
如图4中的(b)或图4中的(c)或图4中的(d)所示，使能省电信号的模式参数时，省电信号可唤醒UE在DRX的激活期内对PDCCH进行监听。
步骤702，基站发送MAC CE，MAC CE携带有载波的状态；
在一个可选的示例中，MAC CE还携带有第一指示，第一指示用于指示变更省电信号的模式参数。
示例的，第一指示可以携带在MAC CE的保留比特R中。当第一个辅载波处于激活状态时，MAC CE中的R置为1，第一指示指示省电信号由使能模式参数变更为去使能模式参数。
结合参考图8，图8示出了本公开一个示例性实施例提供的载波MAC CE的格式图。如图所示，载波MAC CE包含在MAC PDU的子头中,固定为一字节长,包含7比特C域和1比特R域。
C域指示对应辅载波是否激活。当Ci比特置为1,表示标识为i的辅载波激活(i为1至7的整数)；当Ci比特置为0,表示标识为i的辅载波去激活。
主载波总是处于激活状态。如果终端配置了至少一个辅载波,网络则可通过MAC CE对所配置的辅载波进行激活与去激活操作。对于去激活的辅载波,UE不应监听其PDCCH信道，不应在该载波上行共享信道进行数据传输。对于每一个辅载波,UE都会维护一个定时器SCell Deactivation Timer，网络通过RRC消息告知UE该定时器的初始值。
如果UE收到MAC CE激活某一个辅载波,UE应激活对应的辅载波,并启动定时器；如果UE收到MAC CE去激活辅载波或者是辅载波对应的定时器超时,UE应去激活该辅载波,停止定时器，清空相关的混合自动重传请求(Hybrid Automatic Repeat Request，HARQ)缓存。
