Description

一种监测方法及设备 技术领域
本申请实施例涉通信领域，尤其涉及一种终端设备与网络设备在通信过程中进行PDCCH监测方法及设备。
背景技术
当用户设备(user equipment，UE)处于无限资源控制(radio resource control，RRC)连接态时，为了节省UE的功耗，可以为UE配置非连续接收(discontinuous reception，DRX)功能。配置DRX后，UE可以只在某些时间段内监测下行物理控制信道(Physical downlink control channel，PDCCH)，在另外一些时间段内不监测PDCCH，以达到节省UE功耗的目的。
具体地，UE在配置的部分带宽(Bandwidth part，BWP)上与基站进行通信，该下行BWP的配置参数中包括为该UE配置的搜索空间。UE在DRX周期内的一段时间内根据为UE配置的所有搜索空间监测PDCCH。示例的，UE在当前配置的BWP进行通信时最多被配置了10个搜索空间，在DRX周期内的一段时间，UE需要在这10个搜索空间上监测PDCCH，功耗不容忽略。

具体实施方式
下面结合附图和实施例对本申请进行进一步描述。
如图1所示，是本发明实施例提供的通信网络的架构图，包括网络设备和终端设备。网络设备可以调度终端设备接收下行数据或者调度终端设备发送上行数据。本发明实施例中涉及的网络设备包括基站(base station，BS)，基站可能有多种形式，比如宏基站、微基站、中继站和接入点等。示例性地，本发明实施例涉及到的基站可以是新空口(new radio，NR)中的基站，其中，NR中的基站还可以称为发送接收点(transmission reception point，TRP)或下一代节点B(Next generation Node B，gNB)，也可以是全球移动通信系统(global system for mobile communication，GSM)或码分多址(code division multiple access，CDMA)中的基站收发台(base transceiver station，BTS)，也可以是宽带码分多址(wideband code division multiple access，WCDMA)系统中的节点B(nodeB，NB)，还可以是长期演进(long term evolution，LTE)系统中的演进型节点B(Evolutional Node B，eNB或eNodeB)，还可以是未来5G(5th generation)网络中的gNB。本发明实施例涉及到的网络设备也可以包括一种部署在无线接入网中能够和终端进行无线通信的设备，例如，可以是云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器，或者该网络设备可以为中继站、接入点以及未来5G网络中的网络设备或者未来演进的公共陆地移动网络(public land mobile network，PLMN)中的网络设备等，例如，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)、网络设备控制器(base station controller，BSC)、网络设备收发台(base transceiver station,BTS)、家庭网络设备(例如，home evolved nodeB，或home node B，HNB)、基带单元(base band unit，BBU)等。本发明实施例中，实现网络设备的功能的装置可以是网络设备，也可以是支持网络设备实现该功能的装置，例如芯片、电路或者其它装置。本发明实施例中，以实现网络设备的功能的装置是网络设备为例，描述本发明实施例提供的技术方案。
本发明实施例涉及到的终端设备还可以称为终端，可以是一种具有无线收发功能的设备，其可以部署在陆地上，包括室内或室外、手持、穿戴设备、汽车或车载设备；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)。终端设备可以是用户设备(user equipment，UE)。其中，UE包括具有无线通信功能的手持式设备、车载设备、可穿戴设备或计算设备。示例性地，UE可以是手机(mobile phone)、平板电脑或带无线收发功能的电脑。终端设备还可以是虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制中的无线终端、无人驾驶中的无线终端、远程医疗中的无线终端、智能电网中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等等。本发明实施例中，实现终端的功能的装置可以是终端，也可以是支持终端实现该功能的装置，例如芯片、电路或者其它装置。本发明实施例中，以实现终端的功能的装置是终端为例，描述本发明实施例提供的技术方案。
通常，终端设备无论是接收下行数据还是发送上行数据都需要网络设备的调度，网络设备都可以利用PDCCH对终端设备进行调度。如：PDCCH可以承载下行调度信息，以便终端设备接收物理下行数 据信道(physical downlink，PDSCH)；或者，PDCCH可以发送上行调度信息，以便终端设备发送物理上行数据信道(physical uplink，PUSCH)。终端设备在成功接收PDCCH之前需要监听一个候选PDCCH集合，即终端设备根据所要监听的DCI format尝试解码该集合中的每一个PDCCH。如果终端设备在监听过程中成功解码了搜索空间中的一个PDCCH，意味着终端设备成功接收了该PDCCH。需要说明的是，搜索空间是终端设备用来确定候选PDCCH集合的，对于每个搜索空间，网络设备可以配置搜索空间的参数，包括搜索空间索引、关联的控制资源集、PDCCH监测周期、每个PDCCH监测周期中PDCCH监测的持续时间、每个CCE聚合等级下的候选PDCCH数量、监测的DCI格式(DCI format)等。终端设备可以根据搜索空间的参数，确定监测的候选PDCCH集合。
LTE和NR中还定义了DRX(discontinuous reception，非连续接收)来降低终端设备进行PDCCH监听的功耗。连接态下的DRX也可以称为C-DRX(connected discontinuous reception，连接态下的非连续接收)。DRX的基本原理是，网络设备为connected状态的终端设备配置DRX参数，DRX参数可以包括DRX周期(cycle)。参考图2，DRX周期包括“On Duration”和“Opportunity for DRX”，其中，“On Duration”可以称为开启持续时间，“Opportunity for DRX”可以称为DRX机会。在“On Duration”内，终端设备监测PDCCH；在“Opportunity for DRX”时间内，终端设备可以不进行PDCCH监测以减少功耗。
或者，网络设备向终端设备发送一个指示信息，通过指示信息减少终端设备监测PDCCH的功耗。指示信息用于指示终端设备在接下来的几个时隙(slot)内不需要监测PDCCH。或者，网络设备在On Duration之前发送一个指示信息，用于指示该指示信息之后的On Duration终端设备需要监测PDCCH，或者不需要监测PDCCH。
在以上两种减少终端设备功耗的方案中，终端设备需要对网络设备为终端设备配置的搜索空间中的所有PDCCH进行监听、尝试解码，功耗不容忽略。示例的，在NR中，终端在当前配置的BWP(Bandwidth part)进行通信时最多可以被配置10个搜索空间，在DRX周期的On Duration内，UE需要监测、尝试解码这10个搜索空间包括所有PDCCH，功耗很大。
本发明实施例提供一种监测方法，终端设备获取第一搜索空间配置和第二搜索空间配置。其中，所述第一搜索空间配置包括第一搜索空间集合，所述第二搜索空间配置包括第二搜索空间集合，所述第一搜索空间集合与所述第二搜索空间集合不同；或者，所述第一搜索空间配置包括第一搜索空间参数，所述第二搜索空间配置包括第二搜索空间参数，所述第一搜索空间参数与所述第二搜索空间参数不同。进一步，若满足第一条件，终端设备则根据第一搜索空间配置监测物理下行控制信道PDCCH；所述第一条件包括：第一定时器未处于运行状态；若满足第二条件，所述终端设备则根据第二搜索空间配置监测PDCCH；所述第二条件包括：所述第一定时器处于运行状态。本发明实施例中，第一搜索空间配置和第二搜索空间配置可以是不同的搜索空间集合，第一搜索空间集合和/或第二搜索空间集合可以不包括终端设备的全部搜索空间，如此，终端设备只需要监测终端设备的部分搜索空间中的PDCCH，极大地降低了终端设备的功耗。当然，第一搜索空间配置和第二搜索空间配置可以是不同的搜索空间参数，本发明实施例可以通过为终端设备配置不同的搜索空间参数，调整终端设备监测的PDCCH的资源，从而降低了终端设备的功耗。

本发明实施例提供一种监测方法，如图4所示，所述方法包括以下步骤：
步骤401、终端设备获取第一搜索空间配置和第二搜索空间配置。
具体实现中，终端设备可以通过网络设备下发的信令获取第一搜索空间配置和第二搜索空间配置，也可以获取预配的第一搜索空间配置和第二搜索空间配置。具体地，网络设备可以通过两条信令分别通知第一搜索空间配置和第二搜索空间配置，示例的，终端设备接收网络设备发送的第一信息，所述第一信息包括或指示所述第一搜索空间配置；终端设备接收网络设备发送的第二信息，所述第二信息包括或指示所述第二搜索空间配置。也就是说网络设备将上述第一信息和第二信息封装在两条信令中分别下发给终端设备，当然，网络设备也可以将上述第一信息和第二信息封装在同一条信令中统一下发给终端设备，或者，网络设备也可以只向终端设备通知第一搜索空间配置和第二搜索空间配置中的一个，终端设 备可以根据第一搜索空间配置推导出第二搜索空间配置，或是根据第二搜索空间配置推导出第一搜索空间配置。需要说明的是，搜索空间配置可以是搜索空间集合，即由一个或多个搜索空间构成的集合，其中，终端设备可以根据搜索空间确定需要监听的PDCCH集合。另外，搜索空间配置还可以是搜索空间参数，如：PDCCH监测周期、每个PDCCH监测周期中PDCCH监测的持续时间、候选PDCCH数量、CCE聚合等级或关联的控制资源集中的一种或多种，终端设备可以根据搜索空间参数确定需要监听的PDCCH的资源。
在一些实施例中，第一搜索空间配置包括第一搜索空间集合，第二搜索空间配置包括第二搜索空间集合，第一搜索空间集合与第二搜索空间集合不同。
具体实现中，第一搜索空间集合可以是第二搜索空间集合的子集。示例的，第二搜索空间集合包括搜索空间1、搜索空间2、搜索空间3、搜索空间4以及搜索空间5。第一搜索空间结合包括搜索空间1、搜索空间2。
可选的，第一搜索空间集合与第二搜索空间集合的交集可以为空集，也就是说第一搜索空间集合与第二搜索空间集合中没有相同的搜索空间。示例的，第二搜索空间集合包括搜索空间3、搜索空间4以及搜索空间5；第一搜索空间集合包括搜索空间1和搜索空间2。
可选的，第一搜索空间集合与第二搜索空间集合的交集可以为非空集，即第一搜索空间集合与第二搜索空间集合中有相同的搜索空间。示例的，第二搜索空间集合包括搜索空间3、搜索空间4以及搜索空间5；第一搜索空间集合包括搜索空间2和搜索空间3。
网络设备可以给终端设备配置BWP(即系统带宽的一部分)，终端设备可以在网络设备配置的BWP上与网络设备进行通信。BWP可以分为上行BWP和下行BWP，终端设备在上行BWP上向网络设备发送上行数据，在下行BWP接收网络设备发送的下行数据，如：PDCCH。通常，对于终端设备的一个服务小区的每个下行BWP，终端设备最多可被配置10个搜索空间。对于每个搜索空间，UE可以被配置以下一个或多个搜索空间参数：搜索空间索引、关联的控制资源集、PDCCH监测周期、每个PDCCH监测周期中PDCCH监测的持续时间、每个控制信道单元(control channel elements，CCE)聚合等级下的候选PDCCH数量、监测的DCI格式(DCI format)。其中，PDCCH监测周期和持续时间的时间单位为时隙(slot)。终端设备可以根据控制资源集和搜索空间确定需要监测的候选PDCCH的资源。另外，网络设备可以针对每一个终端设备配置搜索空间，示例的，通过为终端设备配置UE specific(专门针对UE的)PDCCH参数为终端设备特定配置用于监测PDCCH的搜索空间，终端设备可以进行PDCCH监测的搜索空间为终端设备的UE specific PDCCH参数中的一个或多个搜索空间。或者，网络设备可以针对每一个小区配置搜索空间，示例的，通过为终端设备配置cell specific(专门针对小区的)PDCCH参数给终端设备配置用于监测PDCCH的搜索空间，为终端设备配置的cell specific PDCCH参数与为终端设备所在的服务小区下的其他终端设备配置的cell specific PDCCH参数相同。
具体实现中，第一搜索空间集合和第二搜索空间集合中的搜索空间可以是UE specific PDCCH参数中的一个或多个搜索空间。
可选地，第一搜索空间集合包括cell specific PDCCH参数中的搜索空间以及一个或多个UE specific PDCCH参数中的搜索空间，第二搜索空间集合包括终端设备被配置的所有的搜索空间。示例的，终端设备被配置的cell specific PDCCH参数中有搜索空间1、搜索空间2，终端设备被配置的UE specific PDCCH参数中有搜索空间3、搜索空间4、搜索空间5。第一搜索空间集合包括搜索空间1、搜索空间2、搜索空间3，第二搜索空间集合包括搜索空间1、搜索空间2、搜索空间3、搜索空间4、搜索空间5。
可选地，第一搜索空间集合和第二搜索空间集合均包括cell specific PDCCH参数中的搜索空间以及一个或多个UE specific PDCCH参数中的搜索空间。在一些实施例中，第一搜索空间集合和第二搜索 空间集合所包括的cell specific PDCCH参数中的搜索空间相同，第一搜索空间集合和第二搜索空间集合所包括的UE specific PDCCH参数中的搜索空间不同。示例的，cell specific PDCCH参数中包括搜索空间1、搜索空间2，UE specific PDCCH参数中包括搜索空间3、搜索空间4、搜索空间5。若第一搜索空间集合与第二搜索空间集合所包括的UE specific PDCCH参数中的搜索空间均不同，例如，第一搜索空间包括搜索空间1、搜索空间2、搜索空间3，第二组搜索空间包括搜索空间1、搜索空间2、搜索空间4、搜索空间5。若第一搜索空间集合与第二搜索空间集合所包括的UE specific PDCCH参数中的搜索空间均不同，例如，第一组搜索空间包括搜索空间1、搜索空间2、搜索空间3、搜索空间4，第二组搜索空间包括搜索空间1、搜索空间2、搜索空间4、搜索空间5。
可选地，第一搜索空间集合包括cell specific PDCCH参数中的搜索空间，第二搜索空间集合包括cell specific PDCCH参数中的搜索空间以及UE specific PDCCH参数中的搜索空间。
在一些实施例中，第一搜索空间集合可以为终端设备的默认搜索空间组成的集合。网络设备可为终端设备配置一个或多个默认的搜索空间。默认搜索空间可以是网络设备为终端设备配置的所有搜索空间的子集。
在一些实施例中，第一搜索空间集合关联的控制资源集为UE的默认控制资源集。需要说明的是，网络设备可以为终端设备配置一个或多个控制资源集，网络设备为终端设备配置的“一个或多个控制资源集”可以称为终端设备的默认控制资源集。
在一些实施例中，还可以在同一个搜索空间中通过不同的搜索空间参数调整监听PDCCH的资源。本发明实施例中，第一搜索空间配置包括第一搜索空间参数，第二搜索空间配置包括第二搜索空间参数，第一搜索空间参数与第二搜索空间参数不同。也就是说，终端设备可以根据不同的搜索空间参数监测PDCCH。示例的，终端设备根据不同的PDCCH监测周期监测PDCCH，或者终端设备根据不同的PDCCH监测的持续时间监测PDCCH，或者，终端设备根据不同的候选PDCCH数量监测PDCCH。搜索空间参数可以包括PDCCH监测周期、每个PDCCH监测周期中PDCCH监测的持续时间、候选PDCCH数量、CCE聚合等级或关联的控制资源集中的一种或多种。可选的，候选PDCCH数量可以是每个CCE聚合等级下的候选PDCCH数量。
在一些实施例中，终端设备可以被配置第二搜索空间参数，终端设备可以根据第二搜索空间参数确定出第一搜索空间参数。具体实现中，终端设备可以根据第二搜索空间参数和缩放因子确定出第一搜索空间参数，其中缩放因子可以是网络设备配置的，也可以是预先定义的。示例的，第一搜索空间参数包括第一监测PDCCH周期，第二搜索空间参数包括第二监测PDCCH周期。网络设备为终端设备配置第二监测PDCCH周期，终端设备确定第一监测PDCCH周期为第二监测PDCCH周期与缩放因子乘积。
在一些实施例中，第一搜索空间参数可以为搜索空间的默认参数。搜索空间的默认参数可以是网络设备为终端设备预先配置的搜索空间参数。示例的，网络设备为终端设备配置的PDCCH监测周期、或候选PDCCH数量。
在一些实施例中，第一搜索空间参数中关联的控制资源集为UE的默认控制资源集。
具体实现中，可以在搜索空间IE(Information element)中指示第一搜索空间参数和第二搜索空间参数。示例的，搜索空间参数可以是监测周期和偏移参数，在搜索空间IE中增加第一搜索空间参数和第二搜索空间参数，第一搜索空间参数和第二搜索空间参数的监测周期不同，第一搜索空间参数和第二搜索空间参数的偏移参数不同，第一搜索空间参数和第二搜索空间参数指示不同的监测PDCCH的资源，终端设备可以根据不同的资源监测PDCCH。
如果满足第一条件，则执行步骤402；如果满足第二条件，则执行步骤403。
步骤402、若满足第一条件，终端设备则根据第一搜索空间配置监测物理下行控制信道PDCCH； 所述第一条件包括：第一定时器未处于运行状态。
步骤403、若满足第二条件，所述终端设备则根据第二搜索空间配置监测PDCCH；所述第二条件包括：所述第一定时器处于运行状态。
具体实现中，第一定时器的时长可以是网络设备通过RRC信令配置的。在一些实施例中，该定时器的时长小于非激活定时器(drx-InactivityTimer)的时长。当然，本发明实施例中第一定时器也可以是drx-InactivityTimer，用于确定当终端设备成功解码一个调度新传的PDCCH后监测PDCCH的时间长度。
示例的，第一定时器为网络设备通过RRC信令配置的一个定时器，参考图4a，一开始T1时刻未启动，T2时刻该定时器启动，因此T1时刻至T2时刻该定时器未处于运行状态，终端设备根据第一搜索空间配置监测PDCCH。T2时刻至T3时刻该定时器处于运行状态，终端设备根据第二搜索空间配置监测PDCCH。
需要说明的是，本发明实施例所述的各种定时器一旦启动后，定时器处于运行状态，直到定时器停止或超时；否则，定时器未处于运行状态。若定时器未处于运行状态，定时器可以被启动。若定时器处于运行状态，定时器可以被重启。定时器的值在启动或重启时为其初始值。定时器的时间长度可以理解为定时器从启动或重启持续运行直到超时的时间长度。
本发明实施例还提供了步骤402所涉及的第一条件的其他可能的实现，第一条件具体还可以是如下四种可能：
(1)第一条件除了包括第一定时器未处于运行状态外，还包括第三定时器处于运行状态。
需要说明的是，所述第三定时器用于确定所述终端设备在一个非连续接收DRX周期内监测PDCCH的时间长度，如：on duration timer，或onDurationTimer，或drx-onDurationTimer。也就是说，若第一定时器未处于运行状态且第三定时器处于运行状态，终端设备根据第一搜索空间配置监测PDCCH。所述第三定时器可以在DRX周期的起始时刻开启。或者所述第三定时器在DRX周期中的开启持续时间(On Duration)的起始时刻开启，第三定时器的时间长度为开启持续时间的长度。
(2)在一些实施例中，第一条件除了包括第一定时器未处于运行状态外，还可以包括所述终端设备处于DRX周期中的开启持续时间。也就是说，若第一定时器未处于运行状态且终端设备处于DRX周期中的开启持续时间，终端设备则根据第一搜索空间配置监测物理下行控制信道PDCCH。

示例的，在一些实施例中，若第一定时器未处于运行状态，且下行重传定时器未处于运行状态，终端设备则根据第一搜索空间配置监测物理下行控制信道PDCCH。在另一些实施例中，若第一定时器未处于运行状态，且下行重传定时器未处于运行状态，且上行重传定时器未处于运行状态，终端设备则根据第一搜索空间配置监测物理下行控制信道PDCCH。在另一些实施例中，若第一定时器未处于运行状态，且第三定时器处于运行状态，且下行重传定时器未处于运行状态，终端设备则根据第一搜索空间配置监测物理下行控制信道PDCCH。
其中，上行重传定时器用于确定监测用于指示重传上行传输的PDCCH的时间长度，下行重传定 时器用于确定监测用于指示重传下行传输的PDCCH的时间长度。竞争解决定时器用于确定在随机接入过程中终端设备发送消息三后监测用于指示消息四的PDCCH的时间长度。
(4)在一些实施例中，第一条件为：所述终端设备处于第一时刻与第二时刻之间。其中，所述第二时刻为第三时刻；所述第三时刻为终端设备在所述第一时刻之后接收到第N个PDCCH的时刻；或者，所述第二时刻为所述第三时刻之后间隔第一时长的时刻。所述N为大于或等于1的整数；所述第一时长的长度大于0。若满足第一条件，终端设备根据第一搜索空间配置监测PDCCH。所述第二条件为：所述终端设备处于所述第二时刻之后。若满足第二条件，终端设备根据第二搜索空间配置监测PDCCH。在一些实施例中，第一时刻可以为DRX开启持续时间的起始时刻。在一些实施例中，若在DRX周期中的开启持续时间期间非激活定时器超时，则第一时刻为非激活定时器超时的时刻。
在一些实施例中，若处于以下情况中的一个，所述终端设备则根据所述第二搜索空间配置监测PDCCH，包括：下行重传定时器处于运行状态、上行重传定时器处于运行状态、竞争解决定时器处于运行状态、所述终端设备发送的调度请求处于挂起状态、所述终端设备在成功接收随机接入响应RAR后未接收到指示新传的PDCCH；所述指示新传的PDCCH由小区无线网络临时标识C-RNTI加扰，所述RAR是对目标随机接入前导的响应，所述目标随机接入前导不属于基于竞争的随机接入前导。

本发明实施例还提供了第一搜索空间集合和第二搜索空间集合的配置方法，具体包括如下第一种～第三种这三种配置方法：

或者，该指示信息可以有三种取值，一种取值代表该搜索空间属于第一搜索空间集合，一种取值代表该搜索空间属于第二搜索空间集合，一种取值代表该搜索空间既属于第一搜索空间集合也属于第二搜索空间集合。例如，在SearchSpace IE中包含searchSpaceGroup，searchSpaceGroup可取值包括first、second和both，first表示该搜索空间属于第一搜索空间集合，second表示该搜索空间属于第二搜索空间集合，both表示该搜索空间既属于第一搜索空间集合也属于第二搜索空间集合。在标准中的具体实现可以如下：

(2)在搜索空间IE中包含一个指示信息，该指示信息指示该搜索空间是否属于第一搜索空间集合。该指示信息有两种取值，一种取值代表该搜索空间属于第一搜索空间集合，另一种取值代表该搜索不属于第一搜索空间集合。例如，在SearchSpace IE中包含searchSpaceDefault，searchSpaceDefault可取值包括true和false，true表示该搜索空间属于第一搜索空间集合，false表示该搜索空间不属于第一搜索空间集合。在标准中的具体实现可以如下：

本发明实施例还提供一种监测方法，如图5所示，所述方法包括以下步骤：
步骤501、终端设备获取第一搜索空间配置和第二搜索空间配置。
本发明实施例中第一搜索空间配置包括第一搜索空间集合，第二搜索空间配置包括第二搜索空间集合，第一搜索空间集合与第二搜索空间集合不同；需要说明的是，所谓搜索空间集合即由一个或多个搜索空间构成的集合，其中搜索空间用于确定终端设备需要监听的PDCCH集合。
步骤501的相关描述、说明可以参考本发明实施例对步骤401的相关描述，本发明实施例在此不做赘述。
如果满足第一条件，则执行步骤502；如果满足第二条件，则执行步骤503。
步骤502、若满足第一条件，终端设备则根据第一搜索空间配置监测物理下行控制信道PDCCH；所述第一条件包括：第一定时器未处于运行状态且第三定时器处于运行状态。
具体实现中，第一定时器的时长可以是网络设备通过RRC信令配置的。在一些实施例中，该定时器的时长小于非激活定时器(drx-InactivityTimer)的时长。当然，本发明实施例中第一定时器也可以是drx-InactivityTimer，用于确定当终端设备成功解码一个调度新传的PDCCH后监测PDCCH的时间长度。
另外，所述第三定时器用于确定所述终端设备在一个非连续接收DRX周期内监测PDCCH的时间长度，如：on duration timer，或onDurationTimer，或drx-onDurationTimer。也就是说，若第一定时器未处于运行状态且第三定时器处于运行状态，终端设备则根据第一搜索空间配置监测物理下行控制信道PDCCH。所述第三定时器可以在DRX周期的起始时刻开启。或者所述第三定时器在DRX周期中的开启持续时间(On Duration)的起始时刻开启，第三定时器的时间长度为开启持续时间的长度。
步骤503、若满足第二条件，所述终端设备则根据第二搜索空间配置监测PDCCH；所述第二条件 包括：所述第一定时器处于运行状态。
示例的，以第一定时器为drx-InactivityTimer，第三定时器为On DurationTimer作为示例。参考图5a，T4时刻开始为一个DRX周期中的On Duration，T5时刻开始rx-InactivityTimer启动。即T4时刻至T5时刻第三定时器在运行状态，并且第一定时器drx-InactivityTimer未处于运行状态，终端设备根据第一搜索空间配置监测PDCCH。T5时刻至T6时刻第一定时器drx-InactivityTimer处于运行状态，终端设备根据第二搜索空间配置监测PDCCH。
本发明实施例提供的方法中，网络设备通过配置终端设备的搜索空间使得终端设备在第一搜索空间配置监测PDCCH的功耗低于终端在第二搜索空间配置监测PDCCH的功耗，从而降低终端设备监测PDCCH的功耗。例如，配置第一搜索空间集合是第二搜索空间集合的子集，或者配置第一搜索空间参数指示的PDCCH资源较少，或者第一搜索空间参数指示的候选PDCCH的数量较少，或者第一搜索空间参数指示的PDCCH监测周期较长等。
本发明实施例还提供了步骤502所涉及的第一条件的其他可能的实现，在一些实施例中，所述第一条件还包括以下情况中的一个或多个：下行重传定时器(如drx-Retransmission TimerDL，或drx-RetransmissionTimer)未处于运行状态；上行重传定时器(如drx-Retransmission TimerUL，或drx-ULRetransmissionTimer)未处于运行状态；竞争解决定时器(如ra-ContentionResolutionTimer，或mac-ContentionResolutionTimer)未处于运行状态；所述终端设备发送的调度请求未处于挂起状态；所述终端设备未处于“在成功接收随机接入响应RAR后未接收到指示新传的PDCCH”，所述指示新传的PDCCH由小区无线网络临时标识C-RNTI加扰，所述RAR是对目标随机接入前导的响应，所述目标随机接入前导不属于基于竞争的随机接入前导。
示例的，在一些实施例中，若第一定时器未处于运行状态，且第三定时器处于运行状态，且下行重传定时器未处于运行状态，终端设备则根据第一搜索空间配置监测物理下行控制信道PDCCH。在另一些实施例中，若第一定时器未处于运行状态，且第三定时器处于运行状态，且下行重传定时器未处于运行状态，且上行重传定时器未处于运行状态，终端设备则根据第一搜索空间配置监测物理下行控制信道PDCCH。
其中，上行重传定时器用于确定监测用于指示重传上行传输的PDCCH的时间长度，下行重传定时器用于确定监测用于指示重传下行传输的PDCCH的时间长度。竞争解决定时器用于确定在随机接入过程中终端设备发送消息三后监测用于指示消息四的PDCCH的时间长度。
在一些实施例中，若处于以下情况中的一个，所述终端设备则根据所述第二搜索空间配置监测PDCCH，包括：下行重传定时器处于运行状态、上行重传定时器处于运行状态、竞争解决定时器处于运行状态、所述终端设备发送的调度请求处于挂起状态、所述终端设备在成功接收随机接入响应RAR后未接收到指示新传的PDCCH；所述指示新传的PDCCH由小区无线网络临时标识C-RNTI加扰，所述RAR是对目标随机接入前导的响应，所述目标随机接入前导不属于基于竞争的随机接入前导。
另外，终端设备监测的PDCCH可以是小区无线网络临时标识(cell radio network temporary identity，C-RNTI)、配置调度无线网络临时标识(Configured Scheduling RNTI，CS-RNTI)、间断无线网络临时标识(Interruption RNTI，INT-RNTI)、时隙格式指示无线网络临时标识(Slot Format Indication RNTI，SFI-RNTI)、半静态信道状态信息无线网络临时标识(Semi-Persistent CSI RNTI，SP-CSI-RNTI)、传输功率控制无线网络临时标识(Transmit Power Control RNTI，TPC-PUCCH-RNTI)、传输功率控制物理上行共享信道无线网络临时标识(Transmit Power Control Physical Uplink Shared Channel RNTI，TPC-PUSCH-RNTI)或者传输功率控制探测参考信号无线网络临时标识(Transmit Power Control Souding Reference Signal RNTI，TPC-SRS-RNTI)加扰的PDCCH。
本发明实施例还提供一种监测方法，如图6所示，所述方法包括以下步骤：
601、终端设备获取第一搜索空间配置和第二搜索空间配置。
其中，所述第一搜索空间配置包括第一搜索空间集合，所述第二搜索空间配置包括第二搜索空间集合，所述第一搜索空间集合与所述第二搜索空间集合不同。在一些实施例中，所述第一搜索空间集合可以为所述第二搜索空间集合的子集。需要说明的是，第一搜索空间集合与第二搜索空间集合的详细配置可以参考步骤401相关描述提供的多种实现可能，本发明实施例在此不做赘述。
在一些实施例中，第一搜索空间配置包括第一搜索空间参数，所述第二搜索空间配置包括第二搜索空间参数，所述第一搜索空间参数与所述第二搜索空间参数不同。具体地，搜索空间参数包括以下参数中的至少一种：PDCCH监测周期、每个PDCCH监测周期中PDCCH监测的持续时间、候选PDCCH数量、CCE聚合等级、以及关联的控制资源集。需要说明的是，第一搜索空间参数与第二搜索空间参数的详细配置可以参考步骤401相关描述提供的多种实现可能，本发明实施例在此不做赘述。
需要说明的是，终端设备可以通过网络设备下发的信令获取第一搜索空间配置和第二搜索空间配置，也可以获取预配的第一搜索空间配置和第二搜索空间配置。具体地，网络设备可以通过两条信令分别通知第一搜索空间配置和第二搜索空间配置，示例的，终端设备接收网络设备发送的第一信息，所述第一信息包括或指示所述第一搜索空间配置；终端设备接收网络设备发送的第二信息，所述第二信息包括或指示所述第二搜索空间配置。也就是说网络设备将上述第一信息和第二信息封装在两条信令中分别下发给终端设备，当然，网络设备也可以将上述第一信息和第二信息封装在同一条信令中统一下发给终端设备，或者，网络设备也可以只向终端设备通知第一搜索空间配置和第二搜索空间配置中的一个，终端设备可以根据第一搜索空间配置推导出第二搜索空间配置，或是根据第二搜索空间配置推导出第一搜索空间配置。
602、终端设备根据第一搜索空间配置监测第一PDCCH；所述第一PDCCH用于承载指示信息。
其中，所述指示信息用于指示所述终端设备在接收所述指示信息之后的第一时间段内不监测第二PDCCH；或者，所述指示信息用于指示所述终端设备在接收所述指示信息之后的第二时间段内监测所述第二PDCCH；所述第二PDCCH未承载所述指示信息。
一种可能的实现方式中，所述指示信息用于指示所述终端设备在接收所述指示信息之后的第一时间段内不期望第二PDCCH，或者，所述指示信息用于指示网络设备在所述指示信息之后的第一时间段内不会向所述终端设备发送第二PDCCH。
需要说明的是，本发明实施例中的时间段(如：第一时间段、第二时间段)可以是该指示信息之后的一个或多个On Duration，也可以是指示信息之后的N个时间单位后，长度为M个时间单位的时间段，还可以是指示信息之后的L个PDCCH监测时机。其中，时间单位可以是绝对时间，如毫秒，也可以是符号、时隙、子帧等。其中，N大于或等于0，M大于或等于1，L大于或等于1。
在一些实施例中，第二PDCCH可以是用于指示数据传输的PDCCH。
在一些实施例中，第二PDCCH可以是小区无线网络临时标识(cell radio network temporary identity，C-RNTI)、配置调度无线网络临时标识(Configured Scheduling RNTI，CS-RNTI)、间断无线网络临时标识(Interruption RNTI，INT-RNTI)、时隙格式指示无线网络临时标识(Slot Format Indication RNTI，SFI-RNTI)、半静态信道状态信息无线网络临时标识(Semi-Persistent CSI RNTI，SP-CSI-RNTI)、传输功率控制无线网络临时标识(Transmit Power Control RNTI，TPC-PUCCH-RNTI)、传输功率控制物理上行共享信道无线网络临时标识(Transmit Power Control Physical Uplink Shared Channel RNTI，TPC-PUSCH-RNTI)或者传输功率控制探测参考信号无线网络临时标识(Transmit Power Control Souding Reference Signal RNTI，TPC-SRS-RNTI)加扰的PDCCH。
在一些实施例中，所述指示信息还包括或指示第二搜索空间配置。终端设备根据第一搜索空间配置监测第一PDCCH，接收第一PDCCH后获取PDCCH承载的指示信息后，可以获取指示信息中的第二搜索空间配置，进一步，根据指示信息中的第二搜索空间配置监测未承载指示信息的其他PDCCH，即本发明实施例所述第二PDCCH。一种可能的实现方式中，第二搜索空间配置包括第二搜索空间集合，指示信息中包括第二搜索空间集合中的每个搜索空间的索引。另一种可能的实现方式中，第二搜索空间配置包括第二搜索空间集合，指示信息中包括用于指示第二搜索空间集合的域。另一种可能的实现方式中，第二搜索空间配置包括第二搜索空间参数，第二搜索空间参数包括第二监测PDCCH周期，指示信息中包括第二监测PDCCH周期。当然，指示信息也可以不直接包括第二搜索空间配置，通过一些参数来指示所述第二搜索空间配置即可。一种可能的实现方式中，第二搜索空间配置包括第二搜索空间参数，第二搜索空间参数包括第二监测PDCCH周期，指示信息中包括缩放因子，终端设备根据缩放因子确定第二监测PDCCH周期。
603、所述终端设备在所述第一时间段外或所述第二时间段内根据第二搜索空间配置监测所述第二PDCCH。
具体地，如果指示信息指示所述终端设备在接收所述指示信息之后的第一时间段内不监测第二PDCCH，那么终端设备在第一时间段外根据第二搜索空间配置监测所述第二PDCCH。
或者，所述指示信息用于指示所述终端设备在接收所述指示信息之后的第二时间段内监测所述第二PDCCH，那么终端设备在第二时间段内根据第二搜索空间配置监测所述第二PDCCH。
在一些实施例中，所述指示信息还包括所述第二PDCCH指示的PDSCH的MIMO层数。或者，所述指示信息还用于指示所述第二PDCCH指示的PDSCH的MIMO层数。终端设备可以根据指示信息使用相应的MIMO层数接收PDSCH。需要说明的是，指示信息包括或指示的MIMO层数可以是最大MIMO层数层数。
本发明实施例提供的方法中，能够通过指示信息减少PDCCH监测给终端设备带来的功耗。并且终端设备使用不用的搜索空间来监测承载指示信息的PDCCH和未承载指示信息的PDCCH，终端设备不再是利用全部的搜索空间监测PDCCH，也能够达到降低终端设备功耗的效果。
本发明实施例提供一种通信方法，终端设备能够使用合适的MIMO层数接收网络设备发送的PDSCH，以节省终端设备接收PDSCH的功耗。如图7所示，所述方法具体包括：
701、终端设备判断满足第一条件还是第二条件。第一条件包括第一定时器未处于运行状态，第二条件包括第一定时器处于运行状态。
具体实现中，第一定时器的时长可以是网络设备通过RRC信令配置的。在一些实施例中，该定时器的时长小于非激活定时器(drx-InactivityTimer)的时长。当然，本发明实施例中第一定时器也可以是drx-InactivityTimer，用于确定当终端设备成功解码一个调度新传的PDCCH后监测PDCCH的时间长度。
具体实现中，若所述终端设备接收到PDCCH，则启动或重启所述第一定时器；或者，若所述终端设备接收到指示数据传输的PDCCH，则启动或重启所述第一定时器；或者，若所述终端设备接收到指示新传的PDCCH，则启动或重启所述第一定时器；或者，若第二定时器启动或重启，所述终端设备则启动或重启所述第一定时器；所述第二定时器用于确定所述终端设备在接收到指示新传的PDCCH后监测PDCCH的时间长度，如：drx-InactivityTimer。或者，终端设备接收网络设备发送的指示信息，则启动或重启所述第一定时器；其中，指示信息可以是通过下行控制信息(Downlink Contorl Information，DCI)传输，也可以是通过媒介接入控制控制元素(Medium Access Control Control Element，MAC CE)传输。指示数据传输的PDCCH可以是指示上行传输的PDCCH，也可以是指示下行传输的PDCCH。
如果满足第一条件，则执行步骤702；如果满足第二条件，则执行步骤703。
702、若终端设备在满足第一条件时接收到第一PDCCH，所述终端设备根据第一多入多出MIMO层数接收所述第一PDCCH指示的物理下行数据信道PDSCH。
703、若所述终端设备在满足第二条件时接收到第二PDCCH，所述终端设备根据第二MIMO层数接收所述第二PDCCH指示的PDSCH。
具体实现中，所述第一MIMO层数与所述第二MIMO层数不同。在一些实施例中，第一MIMO层数是第一PDCCH指示的PDSCH使用的MIMO层数，第二MIMO层数是第二PDCCH指示的PDSCH使用的MIMO层数。在另一些实施例中，第一MIMO层数是第一PDCCH指示的PDSCH可能使用的最大MIMO层数，第二MIMO层数是第二PDCCH指示的PDSCH可能使用的最大MIMO层数。在一些实施例中，第一MIMO层数小于第二MIMO层数。示例的，第一MIMO层数为2，第二MIMO层数为4。如果满足第一条件，终端设备可以只打开2个接收天线或2个接收链路；若满足第二条件，终端设备需要打开4个接收天线或4个接收链路。这样就尽量降低了终端设备的功耗。
通常，网络设备在下行控制信息(Downlink Control Information，DCI)中指示PDSCH使用的天线端口Antenna port，天线端口的数量就是MIMO层数的大小。当MIMO层数较小时，终端设备可以使用较少的接收天线或接收链路(Rx chain)，当MIMO层数较大时，终端设备需要使用较多的接收天线或接收链路。因此，终端设备使用较大的MIMO层数的功耗高于终端设备使用较小的MIMO层数的功耗。为了降低终端设备的功耗，终端设备可以在不同情况下，使用不同的MIMO层数接收PDSCH。
需要说明的是，第二MIMO层数可以为终端设备的能力信息所指示的终端设备能支持的最大MIMO层数，如：FeatureSetDownlinkPerCC IE中的maxNumberMIMO-LayersPDSCH。
第一MIMO层数可以是网络设备配置的。在网络设备配置第一MIMO层数之前，终端设备可以向网络设备发送指示信息，用于指示其希望或建议的第一MIMO层数。第一MIMO层数还可以是根据第二MIMO层数确定的。示例的，第一MIMO层数为第二MIMO层数除以2的上取整。

需要说明的是，所述第三定时器用于确定所述终端设备在一个非连续接收DRX周期内监测PDCCH的时间长度，如：on duration timer，或onDurationTimer，或drx-onDurationTimer。也就是说，若第一定时器未处于运行状态且第三定时器处于运行状态，终端设备接收到的PDCCH记为第一PDCCH。进一步，终端设备可以根据第一MIMO层数接收第一PDCCH指示的PDSCH。所述第三定时器可以在DRX周期的起始时刻开启。或者所述第三定时器在DRX周期中的开启持续时间(On Duration)的起始时刻开启，第三定时器的时间长度为开启持续时间的长度。
(2)在一些实施例中，第一条件还可以包括所述终端设备处于DRX周期中的开启持续时间。也就是说，若第一定时器未处于运行状态且终端设备处于DRX周期中的开启持续时间，终端设备接收到的PDCCH记为第一PDCCH。进一步，终端设备可以根据第一MIMO层数接收第一PDCCH指示的PDSCH。

示例的，在一些实施例中，若第一定时器未处于运行状态，且下行重传定时器未处于运行状态，终端设备接收到的PDCCH记为第一PDCCH。进一步，终端设备可以根据第一MIMO层数接收第一PDCCH指示的PDSCH。在另一些实施例中，若第一定时器未处于运行状态，且下行重传定时器未处于运行状态，且上行重传定时器未处于运行状态，终端设备接收到的PDCCH记为第一PDCCH，还可以根据第一MIMO层数接收第一PDCCH指示的PDSCH。在另一些实施例中，若第一定时器未处于运行状态，且第三定时器处于运行状态，且下行重传定时器未处于运行状态，终端设备接收到的PDCCH记为第一PDCCH，还可以根据第一MIMO层数接收第一PDCCH指示的PDSCH。
其中，上行重传定时器用于确定监测用于指示重传上行传输的PDCCH的时间长度，下行重传定时器用于确定监测用于指示重传下行传输的PDCCH的时间长度。竞争解决定时器用于确定在随机接入过程中终端设备发送消息三后监测用于指示消息四的PDCCH的时间长度。

在一些实施例中，若处于以下情况中的一个，所述终端设备则根据所述第二MIMO层数接收PDSCH，包括：下行重传定时器处于运行状态、上行重传定时器处于运行状态、竞争解决定时器处于运行状态、所述终端设备发送调度请求且所述调度请求处于挂起状态、所述终端设备在成功接收随机接入响应RAR后未接收到指示新传的PDCCH；所述指示新传的PDCCH由小区无线网络临时标识C-RNTI加扰，所述RAR是对目标随机接入前导的响应，所述目标随机接入前导不属于基于竞争的随机接入前导。
