Description

一种发送物理下行控制信道的配置信息的方法及装置
本申请要求在2018年7月3日提交中国专利局、申请号为201810719558.3、发明名称为“一种发送物理下行控制信道的配置信息的方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种发送物理下行控制信道的配置信息的方法及装置。
背景技术
在5G新无线接入技术(5th Generation New Radio Access Technology，5G NR)系统中，物理下行控制信道(Physical Downlink Control Channel，PDCCH)的配置与控制资源集(control-resource set，CORESET)、搜索空间有关，所述搜索空间是指终端设备在对PDCCH进行监听时，需要进行监听的时间、周期，以及在控制资源集中的位置、控制域分配资源的粒度(control channel element，CCE)的候选集等，每个PDCCH通常会映射在一个或多个CCE上，将多个CCE的集合称之为聚合，聚合等级的量级为聚合等级(Aggregation Level，AL)，若聚合等级越大，则PDCCH将会映射到更多的CCE上，进而PDCCH的传输性能则会更好。
目前，为了实时监听基站发送的PDCCH，终端设备基于无线资源控制(Radio Resource Control，RRC)信令的配置对PDCCH进行监听。基于RRC信令的配置，每个终端设备可以配置多个控制资源集，每个控制资源集配置多个搜索空间，每个搜索空间对应多个聚合等级的配置，由于PDCCH是基于需求发送的，终端设备需要在多个控制资源集、多个搜索空间以及多个聚合等级的配置所对应的PDCCH候选集中的PDCCH进行监听，导致终端设备在一个时隙中会进行多次PDCCH盲检，进而增加了终端设备的功耗。

实施例一
请参考图1，本申请实施例提供一种配置物理下行控制信道的方法，该方法的处理过程如下。
步骤101，基站获取终端设备的状态信息，基于所述终端设备的状态信息生成动态信令，其中，所述终端设备的状态信息包括所述终端设备的业务状态信息或所述终端设备的信道状态信息。
步骤102，基站向终端设备发送所述动态信令，所述动态信令用于指示搜索空间的第一配置信息，其中，所述第一配置信息用于指示所述终端设备对PDCCH进行监听。
当终端设备的状态信息发生改变时，基站基于所述终端设备的状态信息生成动态信令，来指示终端设备在当前状态下，需要监听的搜索空间的第一配置信息。
一般来说，这里所说的第一配置信息包括以下一种或多种指示信息：
所述终端设备需要监听的搜索空间内PDCCH的聚合等级的配置集合的信息；
所述终端设备需要监听的搜索空间内PDCCH的各个聚合等级所包含的候选资源的位置的信息；
所述终端设备需要监听PDCCH的搜索空间集合的信息；
所述终端设备在对监听的PDCCH进行解调时，基于宽带解调参考信号进行信道估计的指示信息。
所述第一配置信息是终端设备对PDCCH进行监控和接收所必备的信息，而且直接和PDCCH搜索的复杂度有必然的关系。
在实际应用中，终端设备除了接收到动态信令的指示外，还会接收到RRC信令，所述RRC信令也用于指示搜索空间的配置相关信息，所述动态信令指示的第一配置信息是根据信道状态或者业务状态进行修改调整的，所述RRC信令指示的第二配置信息比较全面，不是为特定的场景所优化的，所述第二配置信息更新的比较缓慢，动态信令指示的搜索空间的第一配置信息是RRC信令指示的搜索空间的第二配置信息一个子集，因此，终端设备基于所述第一配置信息来指示终端设备对PDCCH进行监听，减少了终端设备PDCCH盲检的次数，降低了终端设备的功耗，进一步提升了用户的体验效果。
当终端设备的业务状态信息不同时，基站会为终端设备配置不同的PDCCH的搜索空间个数，为了支持各种不同的业务，RRC信令所指示的搜索空间的集合较大，所述动态信令将基于终端设备实际支持的业务状况，对所述RRC信令所指示的搜索空间进行调整，即所述动态信令所指示的PDCCH的搜索空间的集合为RRC信令所指示的搜索空间的集合的子集，可见，终端设备基于动态信令所指示的终端设备进行PDCCH监听可以有效的减少终端设备的盲检次数。
另外，终端设备的信道状态不同时，基站为PDCCH的搜索空间配置不同的聚合等级。在本申请实施例中，基站通过信噪比或参考信号接收功率(Reference Signal Receiving Power，RSRP)来确定的终端设备的信道状态，当终端设备信道的信噪比或RSRP不同时，则对应的终端设备信道状态不同。
其中，搜索空间个数和搜索空间的聚合等级会影响到终端盲检的次数(即终端设备对PDCCH进行监听的情况)，所以在该实施例中基站设备基于终端设备的状态信息确定终端 设备当前需要进行PDCCH监听的具体情况，然后基于该具体情况指示终端设备有针对性的进行监听，避免终端设备对基站所配置的信息进行盲目的监听，从而减少盲检的次数。
以下通过几个具体的实例对终端设备状态信息与终端设备对PDCCH进行监听的关系进行说明，以下分别以终端设备信道状态和业务状态下，终端设备对PDCCH进行监听的过程进行说明。
实例1，当终端设备信道的信噪比或RSRP较好时，为了减少发送占用的资源，基站为PDCCH的搜索空间配置低等级的聚合等级AL＝{1，2或4}，所述动态信令指示终端设备需要监听的PDCCH的搜索空间的聚合等级AL＝{1，2或4}；当终端设备信道的信噪比或RSRP较差时，基站为PDCCH的搜索空间配置高等级的聚合等级AL＝{8,16}，所述终动态信令指示终端设备需要监听的PDCCH的搜索空间的聚合等级AL＝{8,16}，由于此时终端设备仅对AL＝8和AL＝16两个聚合等级对应的PDCCH候选集中的PDCCH进行监听，可见基站基于终端设备的状态信息后，在指示终端设备进行PDCCH监听可以有效的减少UE的盲检次数。
实例2，终端设备的业务比较丰富时，为了满足不同业务的需求，基站会为终端设备配置多个PDCCH的搜索空间，所述动态信令指示终端设备需要监听终端设备配置的多个的PDCCH的搜索空间所对应的PDCCH，当终端设备的业务变少时，基站会减少终端设备配置的PDCCH的搜索空间个数，此时，终端配置的PDCCH的搜索空间为终端设备的业务比较丰富时所配置的搜索空间的一部分，动态信令指示终端设备仅对这部分搜索空间所对应的PDCCH进行监听，可见基站基于终端设备的状态信息后，在指示终端设备进行PDCCH监听可以有效的减少UE的盲检次数。
具体的，所述第一配置信息至少包括以下一种指示信息：指示所述终端设备需要监听的搜索空间内PDCCH的聚合等级的配置集合的信息；指示所述终端设备需要监听的搜索空间内PDCCH的各个聚合等级所包含的候选资源的位置的信息；指示所述终端设备需要监听PDCCH的搜索空间集合的信息；指示所述终端设备在对监听的PDCCH进行解调时，基于宽带解调参考信号进行信道估计。
所述动态信令用于指示搜索空间的第一配置信息的方法有多种，包括但不限制于：
方式1、在RRC信令中，包括搜索空间的集合等级(AL)的等级指示，当终端设备的信道状态发生变化时，所述动态信令可基于终端设备实际的需求以及信道的状态对RRC信令所指示的搜索空间的集合等级AL的等级进行的调整。
例如，RRC信令所指示的每个搜索空间的集合等级的集合为AL＝{1，2，4，8，16}，终端设备需要对AL＝1、AL＝2、AL＝4、AL＝8和AL＝16这五个聚合等级对应的PDCCH候选集中的PDCCH进行监听，当终端设备的信道状态较好时，使用动态信令指示每个搜索空间的集合等级的集合为AL＝{1，2，4}，终端设备仅对AL＝1、AL＝2和AL＝4这三个聚合等级对应的PDCCH候选集中的PDCCH进行监听，当终端设备的信道状态较差时动态信令所指示的每个搜索空间的集合等级的集合为AL＝{8,16}，终端设备仅对AL＝8和AL＝16两个聚合等级对应的PDCCH候选集中的PDCCH进行监听，可见基站基于终端设备的状态信息，在指示终端设备进行PDCCH监听可以有效的减少UE的盲检次数。
方式2、对于每个搜索空间，RRC信令都有各个聚合等级所包含的候选资源的位置的指示，当终端设备的信道状态发生变化时，所述动态信令可基于终端设备实际的信道的状态对RRC信令所指示的各个聚合等级所包含的候选资源的位置分布进行针对性的调整。
例如，RRC信令所指示每个搜索空间内PDCCH的各个聚合等级所包含的候选资源的位置分布为{AL1＝2，AL2＝2，AL4＝2，AL8＝1，AL16＝1}，当终端设备的信道状态较好时，为了减小聚合等级发送所占用的资源，将更多的PDCCH候选集配置到较低的聚合等级上，使用所述动态信令对每个搜索空间内PDCCH的各个聚合等级所包含的候选资源的位置分布进行更改为{AL1＝4，AL2＝4}，增加了较小的聚合等级AL1＝4，AL2＝4对应的PDCCH候选集的分布，当聚合等级较小时，PDCCH发送所占用的资源也更小，可见基站基于终端设备的状态信息，在指示终端设备进行PDCCH监听可以有效的减小PDCCH发送所占用的资源。
方式3、为了支持各种不同的业务，RRC信令所指示的搜索空间的集合比较大，当终端设备的业务状态变化时，所述动态信令所指示的搜索空间的集合为RRC信令所指示的搜索空间的集合的一个子集。
例如，RRC信令指示PDCCH搜索空间集合包括{搜索空间1,s搜索空间2,搜索空间3,搜索空间4},终端设备需要对搜索空间1、搜索空间2、搜索空间3、搜索空间4这四个搜索空间所对应的PDCCH候选集进行监听，当终端设备的业务调整或功耗需求有变化时，动态信令指示PDCCH搜索子集为{搜索空间1,搜索空间3}终端设备仅需要对搜索空间1、搜索空间3这两个搜索空间所对应的PDCCH候选集进行监听，可见终端设备基于业务状态指示终端设备进行PDCCH监听可以有效的减小UE的盲检次数。
方式4、为了达到较好的发射分集增益，在RRC信令在配置资源集合时，为PDCCH的解调配置窄带解调信号，基于终端设备实际的情况，如果需要进行调制解调方式的调整，则可以通过动态的指令指示采用宽带的解调信号进行信道的估计。
例如，RRC信令为PDCCH的解调配置窄带解调信号，终端设备在对PDCCH进行盲检时，需要在每个资源元素组(Resource Element Group，REG)上做信道的估计，由于每个PDCCH包括多个REG，因此需要对PDCCH进行多次估计，而基于宽带的解调信号在一个搜索空间内只需要做一次信道估计，可见，基于动态信令所指示的宽带解调信号对信道进行估计可以有效的减少信道估计的次数，进而减少终端侧耗电。
方式5、为上述方式1-4中至少两种方式的组合。
当所述动态信令可基于终端设备实际的需求以及信道的状态对RRC信令所指示的搜索空间的集合等级(AL)的等级进行的调整时，由于基站是基于实际的信道状态进行配置搜索空间的集合，所述动态信令指示终端设备有针对性的去监听搜索空间的集合等级(AL)对应的PDDCCH候选集，进而可以有效的减少终端设备的盲检次数。
当所述动态信令可基于终端设备实际的信道的状态对RRC信令所指示的各个聚合等级所包含的候选资源的位置分布进行针对性的调整时，所述动态指示将PDCCH候选集分配到不同聚合等级上，进而可以有效的调整PDCCH发送所占用的资源。
当所述动态信令所指示的搜索空间的集合为RRC信令所指示的搜索空间的集合的一个子集时，终端设备基于业务状态指示终端设备进行PDCCH监听可以有效的减小UE的盲检次数。
终端通过动态的指令指示采用宽带的解调信号进行信道的估计，不需要对每个REG进行一次估计，仅在一个搜索空间内只需要做一次信道估计，减少了一个搜索空间内信道估计的次数，进而减少终端侧耗电。
在本申请实施例中，为了保证终端设备对PDDCH进行监听，在发送所述动态信令之 前，还包括：发送RRC信令，所述RRC信令用于指示搜索空间的第二配置信息，其中所述动态信令指示的搜索空间的第一配置信息是所述第二配置信息的一个子集。
在本申请实施例中，为了保证动态信令的有效性，所述动态信令至少包括媒体接入控制(media access control，MAC)层信令、分组下行控制信道信令或用户专属下行控制信道信令中的一种信令。其中，基站将所述动态信令发送给终端设备的具体实现方式可以包括：
一、当所述动态信令为所述MAC层信令时，具体包括：
具体的，基站向所述终端设备发送承载所述MAC层信令的物理下行共享信道(physical downlink shared channel，PDSCH)，终端设备接收到所述PDSCH之后，终端设备向基站发送混合自动重传请求-确认(hybrid automatic repeat request-acknowledgement，HARQ-ACK)，终端设备在发送所述HARQ-ACK之后的预设时间点开始对PDCCH进行监听。
本申请实施例中，当所述动态信令为MAC层信令时，终端设备和基站通过所述反馈自动重传请求确认信号，来确定所述动态信令指示终端设备开始对PDCCH进行监听的时间，因此，终端设备和基站确定所述动态信令生效的时间是一致的，避免终端设备和基站在所述动态信令生效的时间上的差异。
二、当所述动态信令为所述分组下行控制信道信令或所述用户专属下行控制信道信令时，包括：
终端设备在接收基站发送的动态信令之前，还接收基站发送的RRC信令，其中，所述RRC信令用于指示搜索空间的第二配置，其中，所述第二配置包括所述第一配置信息，并基于所述第二配置对PDCCH进行监听。
动态信令可以是分组下行控制信道信令或用户专属下行控制信道信令。第一配置信息包括：终端设备需要监听的搜索空间内PDCCH的聚合等级的配置集合的信息，终端设备需要监听的搜索空间内PDCCH的各个聚合等级所包含的候选资源的位置的信息，终端设备需要监听PDCCH的搜索空间集合的信息，终端设备在对监听的PDCCH进行解调时，基于宽带解调参考信号进行信道估计的指示信息，这四种信息中的任意一种或多种信息。
不同的动态信令所指示的第一配置信息不同，例如，分组下行控制信道信令指示的第一配置信息可以包括：终端设备需要监听的搜索空间内PDCCH的聚合等级的配置集合的信息；终端设备需要监听的搜索空间内PDCCH的各个聚合等级所包含的候选资源的位置的信息；用户专属下行控制信道信令指示的第一配置信息可以包括：终端设备需要监听PDCCH的搜索空间集合的信息；终端设备在对监听的PDCCH进行解调时，基于宽带解调参考信号进行信道估计的指示信息，动态信令具体所指示的第一配置信息可以基于终端设备的实际状态信息或实际需求进行配置，在此不进行限制。
终端设备可以接收基站发送的多个不同动态信令，例如，当终端设备接收到分组下行控制信道信令和用户专属下行控制信道信令时，终端设备基于分组下行控制信道信令所指示的第一配置信息以及用户专属下行控制信道信令所指示的第一配置信息对PDCCH进行监听。
基站会在预设的时间窗口发送所述动态信令，终端设备基于所述预设时间窗口对应的时间段内或时间点检测是否发送所述动态信令，并基于是否检测到所述动态信令，来确定终端设备是基于所述动态信令所指示的搜索空间的第一配置信息，还是基于RRC信令所指示的搜索空间的配置对PDCCH进行监听。
当基站发送分组下行控制信道信令或用户专属下行控制信道信令时，终端设备基于所述预设的时间检测是否发送所述动态信令，来确定搜索空间的配置，避免了由于PDCCH丢失，基站所确定终端设备的搜索空间的配置与终端设备所确定的搜索空间的配置不一致，保证了动态信令的有效性。
实施例二
请参考图2，本实施例提供一种接收物理下行控制信道的配置信息的方法，该方法的包括如下步骤。
步骤201，终端设备接收基站发送的动态信令，并基于所述动态信令所指示的搜索空间的第一配置信息对PDCCH进行监听；其中，所述动态信令基于所述终端设备的信道状态信息或者业务状态信息生成的。
当终端设备的状态信息发生改变时，基站基于所述终端设备的状态信息生成动态信令，来指示终端设备在当前状态下，需要监听的搜索空间的第一配置信息，所述第一配置信息为RRC信令所指示的配置信息的子集。因此，通过所述第一配置信息来指示终端设备对PDCCH进行监听，减少了终端设备PDCCH盲检的次数，降低了终端设备的功耗，进一步提升了用户的体验效果。
可选地，终端设备在接收到基站发送的动态信令之后，基于所述动态信令所指示的搜索空间的第一配置信息对PDCCH进行监听，包括：所述的第一配置信息至少包括以下一种指示信息：所述终端设备需要监听的搜索空间内PDCCH的聚合等级的配置集合的信息；所述终端设备需要监听的搜索空间内PDCCH的各个聚合等级所包含的候选资源的位置的信息；所述终端设备需要监听PDCCH的搜索空间集合；所述终端设备在对监听的PDCCH进行解调时，基于宽带解调参考信号进行信道估计的指示信息。
具体的，终端设备基于动态信令所指示的第一配置信息对PDCCH进行监听的过程，可参考图1所示的实施例，不多赘述。
在本申请实施例中，为了保证动态信令的有效性，所述动态信令至少包括MAC层信令、分组下行控制信道信令或用户专属下行控制信道信令中的一种信令。其中，基站将所述动态信令发送给终端设备的具体实现方式可以包括以下两种方式：
一、当所述动态信令为所述MAC层信令时，包括：
终端设备在接收到承载所述MAC层信令的物理下行共享信道PDSCH之后反馈自动重传请求确认信号HARQ-ACK，终端设备在反馈所述HARQ-ACK之后的第N个时隙开始基于所述第一配置信息对所述的物理下行控制信道PDCCH进行监听，所述N为大于等于1的整数。具体实施方式可参考图1所示的实施例，不多赘述。
本申请实施例提供的方案中，终端设备在反馈所述HARQ-ACK之后的第N个时隙开始基于所述第一配置信息对所述的物理下行控制信道PDCCH进行监听，因此，终端设备和基站都是基于所述HARQ-ACK确定所述动态信令生效的时间，避免了基站和终端设备确定的所述动态信令生效时间不一致，导致所述动态信令的时效性不能够得到保证。
二、当所述动态信令为所述分组下行控制信道信令或所述用户专属下行控制信道信令时，包括：
终端设备在接收基站发送的动态信令之前，还接收基站发送的RRC信令，其中，所述RRC信令用于指示搜索空间的第二配置，其中，所述第二配置包括所述第一配置信息，并基于所述第二配置对PDCCH进行监听，终端设备在预设的时间点或在预设的时间段内 检测是否接收到所述动态信令；若接收到所述动态信令，则基于所述第一配置信息去监听PDCCH，否则，基于所述第二配置去监听PDCCH。
本申请实施例提供的方案中，终端通过在预设时间点或在预设的时间段内检测是否接收到所述动态信令，来确定是基于所述第一配置信息去监听PDCCH，还是基于所述第二配置去监听PDCCH，避免了由于PDCCH的丢失，导致基站确定的终端设备的搜索空间的配置和终端设备确定的搜索空间的配置的不一致。
