Description

一种发送、接收下行控制信道的方法、装置、设备及介质 技术领域
本公开涉及无线通信技术领域，尤其涉及一种发送、接收下行控制信道的方法、装置、设备及介质。
背景技术
NR(New Radio,新空口)协议中，将下行数据承载在物理下行共享信道(Physical Downlink Shared CHannel,PDSCH)上，将上行数据承载在物理上行共享信道(Physical Uplink Shared CHannel,PUSCH)上。基站通过承载在PDCCH信道的下行控制信息(Downlink Control Information，DCI)调度PDSCH和PUSCH。
PDCCH信道中包括了公共搜索空间(Common Search Space，CSS)和UE特定搜索空间(User equipment specific Search Space,USS)。其中，CSS用于承载小区公共控制信息、组播控制信息等，也可用于承载UE特定的控制信息。USS用于承载UE特定的控制信息。
R15协议中，PDCCH监听(monitoring)能力是按照单个时隙(slot)为时间单位进行定义的。具体为：根据子载波间隔(SubCarrier spacing,SCS)的不同，规定每个时隙内UE的监听能力。一个slot内UE的监听能力包括此slot内最大的监听次数，以及此时隙内最大的非重叠控制信道单元(control channel element，CCE)的个数。此定义适用于52.6GHZ以下的频率，可选的子载波带宽为15KHz、30KHz、60KHz或120KHz，一个时隙的时长在子载波带宽不同时，对应的具体值不同，例如：对应于15KHz子载波带宽的时隙的时长为1毫秒(ms)，对应于30KHz子载波带宽的时隙的时长为0.5ms，对应于60KHz子载波带宽的时隙的时长为0.25ms，依次类推。随着子载波带宽越大，时隙的时长越短。

具体实施方式
现结合附图和具体实施方式对本公开实施例进一步说明。
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开实施例相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
在高频段(例如60GHz左右的频段)内，为了应对相位噪声，通常会选择使用较大的子载波带宽，例如960KHz。由于较大的子载波带宽对应着较小的时长(此时长是时隙的时长)。在子载波带宽是960KHz时，对应的一个slot的时长为1/64毫秒(ms)，在此较短的时长内，用户设备可能无法在每个时隙上都执行针对PDCCH信道的监听，因而可以引入跨度PDCCH监听模式(span PDCCH monitoring pattern)或者称为多时隙跨度PDCCH监听模式(multi-slot span PDCCH monitoring pattern)，其中，一个多时隙跨度包括一个以上的时隙，在跨度PDCCH监听模式内按照跨度为单位定义用户设备跨度内USS监听能力，在多时隙跨度PDCCH监听模式内按照多时隙跨度为单位定义用户设备跨度内USS监听能力。
在跨度PDCCH监听模式(span PDCCH monitoring pattern)或者称为多时隙跨度PDCCH监听模式(multi-slot span PDCCH monitoring pattern)下，一个多时隙跨度内并不是所有时隙都配置有PDCCH，而是一个多时隙跨度中的一个或者几个时隙配置有PDCCH。在本文中将配置有PDCCH的时隙称为PDCCH时隙。终端需要监听的DCI只承载在该多时隙跨度中的一个或者少量几个PDCCH时隙上。从而在一个多时隙跨度中的多个时隙被配置有PDCCH的情况下，要求用户设备对一个多时隙跨度中的所有PDCCH时隙进行监听，会导致用户设备的处理能力的浪费。如何在针对多时隙跨度进行监听时节省处理能力，是需要解决的问题。
本公开实施例提供了一种发送下行控制信息的方法，此方法应用于网络侧设备。例如此网络侧设备是基站设备。参照图1，图1是根据一示例性实施例示出的一种发送下行控制信息的方法的流程图，如图1所示，此发送下行控制信息的方法包括：

在一实施方式中，PDCCH时隙是多时隙PDCCH监听跨度中配置有PDCCH的时隙。在一实施方式中，节能监听指示信息所指示的操作可以称为执行节能监听，或者节能监听指示信息所指示的模式是节能监听模式。
本公开实施例中，网络侧设备向用户设备发送节能监听指示信息，以指示在多时隙PDCCH监听跨度中的一个PDCCH时隙的搜索空间上监听到所述至少一DCI格式后，禁止在所述多时隙PDCCH监听跨度中所述一个PDCCH时隙之后的各PDCCH时隙的搜索空间上对所述至少一DCI格式执行监听，从而使用户设备在多时隙PDCCH监听跨度中的一个PDCCH时隙的搜索空间上监听到所述至少一DCI格式后，无需再针对此DCI格式进行监听，从而不必对多时隙PDCCH监听跨度中所有PDCCH时隙都进行监听，可以节省用户设备的处理能力。
