Description

传输物理下行控制信道配置信息的方法、装置及存储介质 技术领域
本公开涉及无线通信技术领域，尤其涉及一种传输物理下行控制信道(physical downlink control channel，PDCCH)配置信息的方法、装置及可读存储介质。
背景技术
目前，新无线(new radio，NR)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。基站通过承载在物理下行控制信道(physical downlink control channel，PDCCH)信道的下行控制信息(downlink control information，DCI)调度PDSCH和PUSCH。
PDCCH信道中包括公共搜索空间(common search space，CSS)和用户设备特定搜索空间(user equipment specific search space，USS)。其中，CSS用于承载小区公共控制信息、组播控制信息等信息，也可用于承载用户设备(user equipment，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UE在每个时隙内的监听能力。UE在一个时隙内的监听能力包括此时隙内最大的监听次数，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。
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。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)，例如：在子载波带宽是960KHz时，对应的一个时隙的时长为1/64毫秒(ms)，在此较短的时长内，UE可能无法在每个时隙都执行针对PDCCH信道的监听。
综上，在使用的子载波间隔越大时，可能导致用户设备无法在每个时域单元上均完成对PDCCH的监听，从而影响用户设备监听PDCCH的效果以及对PDCCH的接收，使终端的处理性能下降，需要优化。
发明内容
有鉴于此，本公开实施例提供了一种传输物理下行控制信道配置信息的方法、装置、设备及可读存储介质，用以为用户设备节能。
第一方面，本公开实施例提供了一种传输物理下行控制信道配置信息的方法，所述方法由网络设备执行，或者由网络设备中的芯片执行。其中网络设备可以包括接入网设备，例如基站、nodeB等。
此方法包括：网络设备向用户设备发送物理下行控制信道PDCCH的配置信息，所述PDCCH的配置信息用于指示第一时频资源，所述第一时频资源用于发送PDCCH，且位于多时隙组中的多个连续的时域单元中。
采用此方法，通过配置用于发送PDCCH的第一时频资源位于多时隙组中的多个连续的时域单元上，使用户设备在接收PDCCH时可以在连续的时域单元上持续接收，相比于从间隔的时域单元上接收PDCCH，为用户设备提供节能的可能，有利于用户设备的节能。
所述第一时频资源在所述多时隙组的时频资源中占用的时域单元的最大数量与所述多时隙组的时频资源包括的时域单元的数量相关；或者，所述第一时频资源在所述多时隙组的时频资源中占用的时域单元的最大数量与子载波间隔相关。
采用此方法，使第一时频资源在所述多时隙组的时频资源中占用的时域单元的最大数量与所述多时隙组的时频资源包括的时域单元的数量相关，从而使第一时频资源在所述多时隙组的时频资源中占用的时域单元的最大数量随着时域资源不同的时隙组而相应的调整，使第一时频资源在所述多时隙组的时频资源中占用的时域单元的最大数量的设置方式更智能。
所述第一时频资源对应的控制资源集合在一个时域单元上占用的连续OFDM符号数大于3。

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。
如图1所示，本申请实施例提供的传输PDCCH配置信息的方法可应用于无线通信系统100，该无线通信系统可以包括终端设备101以及网络设备102。其中，终端设备101被配置为支持载波聚合，终端设备101可连接至网络设备102的多个载波单元，包括一个主载波单元以及一个或多个辅载波单元。
应理解，以上无线通信系统100既可适用于低频场景(sub 6G)，也可适用于高频场景(above 6 G)。无线通信系统100的应用场景包括但不限于长期演进(long term evolution，LTE)系统、LTE频分双工(frequency division duplex，FDD)系统、LTE时分双工(time division duplex，TDD)系统、全球互联微波接入(worldwide interoperability for micro wave access，WiMAX)通信系统、云无线接入网络(cloud radio access network，CRAN)系统、未来的第五代(5th-Generation，5G)系统、新无线(new radio，NR)通信系统或未来的演进的公共陆地移动网络(public land mobile network，PLMN)系统等。
以上所示终端设备101可以是用户设备(user equipment，UE)、终端(terminal)、接入终端、终端单元、终端站、移动台(mobile station，MS)、远方站、远程终端、移动终端(mobile terminal)、无线通信设备、终端代理或终端设备等。该终端设备101可具备无线收发功能，其能够与一个或多个通信系统的一个或多个网络设备进行通信(如无线通信)，并接受网络设备提供的网络服务，这里的网络设备包括但不限于图示网络设备102。
其中，终端设备101可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字处理personal digital assistant，PDA)设备、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备、未来5G网络中的终端设备或者未来演进的PLMN网络中的终端 设备等。
网络设备102可以是接入网设备(或称接入网站点)。其中，接入网设备是指有提供网络接入功能的设备，如无线接入网(radio access network，RAN)基站等等。网络设备102具体可包括基站(base station，BS)，或包括基站以及用于控制基站的无线资源管理设备等。该网络设备102还可包括中继站(中继设备)、接入点以及未来5G网络中的基站、未来演进的PLMN网络中的基站或者NR基站等。网络设备102可以是可穿戴设备或车载设备。网络设备102也可以是具有通信模块的通信芯片。
比如，网络设备102包括但不限于：5G中的下一代基站(gnodeB，gNB)、LTE系统中的演进型节点B(evolved node B，eNB)、无线网络控制器(radio network controller，RNC)、WCDMA系统中的节点B(node B，NB)、CRAN系统下的无线控制器、基站控制器(basestation controller，BSC)、GSM系统或CDMA系统中的基站收发台(base transceiver station，BTS)、家庭基站(例如，home evolved nodeB，或home node B，HNB)、基带单元(baseband unit，BBU)、传输点(transmitting and receiving point，TRP)、发射点(transmitting point，TP)或移动交换中心等。
以NR为例，终端设备101对于PDCCH的处理原则是，终端设备101在一个或多个搜索空间(search space，SS)监听网络设备102发送的PDCCH以接收PDCCH所承载的下行控制信息(downlink control information，DCI)(在本申请中为简便说明，下行控制信息也可称为控制信息)。其中，SS即终端设备101需要监听PDCCH的候选位置集合，SS包括公共搜索空间(common search space，CSS)和UE专属搜索空间(UE specific search space，USS)，并且NR中对于PDCCH引入了控制资源集合(control resource set，CORESET)的概念。一个CORESET是终端设备101尝试使用一个或多个SS检测PDCCH的候选时频资源，CORESET可包括频域上连续多个资源块以及时域上连续多个符号。CORESET的时频位置可位于BWP和一个时隙的任意位置。CORESET的时域及频域位置可由网络设备102侧通过高层信令半静态配置。
一个PDCCH使用的资源由一个CORESET内的一个或多个CCE聚合构成，一个或多个CCE的数量与PDCCH的AL对应。目前NR支持的PDCCH的聚合等级与PDCCH使用的CCE的数量之间具有相应的对应关系。一个CCE 可由6个资源单元组(resource element group，REG)组成，每个REG在时域上包括一个符号、频域上包括一个资源块(resource block，RB)。其中一个RB在频域上可包括12个资源单元(resource-element，RE)。当监听网络设备102发送的一个PDCCH时，终端设备101需要在网络设备102配置的每个PDCCH的候选位置，根据PDCCH的每一个可能的聚合等级进行检测，因此，在未知PDCCH的聚合等级的情况下，终端设备101在每个候选位置进行多次监听。
本公开实施例中引入了多时隙PDCCH监听模式(multi-slot PDCCH monitoring pattern)，以及此模式下引入了PDCCH监听对应的多时隙组(multi-slot group)或者多时隙PDCCH监听跨度(multi-slot PDCCH monitoring span)。其中，多时隙组中包括多个时域单元，多时隙PDCCH监听跨度中包括多个时域单元，所述时域单元是一个时隙或半个时隙。
其中，PDCCH监听对应的多时隙组与多时隙PDCCH监听跨度表示同一概念，是对同一概念的不同描述方式。本公开中的多时隙组也可以替换为多时隙PDCCH监听跨度。
在多时隙PDCCH监听模式(multi-slot PDCCH monitoring pattern)下，一个多时隙组内并不是所有的时域单元都配置有PDCCH，而是其中部分时域单元上配置有PDCCH，例如：多时隙组中一个或者部分几个时隙配置有PDCCH，其它时隙上不配置PDCCH。可以将配置有PDCCH的时隙称为PDCCH时隙。在此多时隙PDCCH监听模式下，PDCCH监听能力是以多时隙组为单位进行定义的。
本公开实施例提供了一种传输PDCCH配置信息的方法，参照图2，图2是根据一示例性实施例示出的一种传输PDCCH配置信息的方法的流程图，如图2所示，此方法包括：
步骤S21，网络设备102向用户设备101发送PDCCH的配置信息，所述PDCCH的配置信息用于指示第一时频资源，所述第一时频资源用于发送PDCCH，且位于多时隙组中的多个连续的时域单元中。
步骤S22，用户设备101从网络设备102接收PDCCH的配置信息，所述PDCCH的配置信息用于指示第一时频资源，所述第一时频资源用于发送PDCCH，且位于多时隙组中的多个连续的时域单元中。
其中，所述第一时频资源位于多时隙组的多个连续的时域单元中，可以 理解为所述第一时频资源占用的多个时域单元是多时隙组的时频资源中一部分连续的时域资源。
在一实施方式中，所述时域单元是时隙。
在一实施方式中，所述时域单元是半时隙。
在一实施方式中，网络设备102向用户设备101发送PDCCH的配置信息后，在所述第一时频资源上发送所述PDCCH。用户设备101在所述第一时频资源上接收所述PDCCH。
在一示例中，多时隙组中共包括8个时隙，网络设备102向用户设备101发送PDCCH的配置信息，此配置信息指示的第一时频资源是所述8个时隙中的第1、2、3、4个时隙，此第1、2、3、4个时隙中每个时隙对应于一个PDCCH。网络设备102在所述8个时隙中的第1至4个时隙上发送相应的4个PDCCH。用户设备101从网络设备102中接收到PDCCH的配置信息后，在所述中的第1至4个时隙上接收4个PDCCH。
本公开实施例中，通过配置用于发送PDCCH的第一时频资源位于多时隙组中的多个连续的时域单元上，使用户设备101在接收PDCCH时可以在连续的时域单元上持续接收，相比于从间隔的时域单元上接收PDCCH，为用户设备101提供节能的可能，有利于用户设备101的节能。
需要注意的是，本公开实施例中使第一时频资源在多时隙组中的时域资源上连续分布，是希望用户设备101接收PDCCH的时间较为集中，当用户设备101接收PDCCH的行为完成后，可以关闭部分射频器件，因而达到节能的效果。而用户设备101针对PDCCH的处理并不必须与接收PDCCH同步进行，而是可以在接收PDCCH的过程中同步进行，也可以在接收PDCCH完成后再进行。本公开实施例中只是为用户设备101提供了一种节能的可能，一个执行功能良好的用户设备101可以在一个多时隙组中接收完所有的PDCCH后，根据自身能力判断是否要进入节能模式，本公开实施例并没有强行规定用户设备101必须执行节能模式转换的操作。
本公开实施例提供了一种传输PDCCH配置信息的方法，此方法包括：
网络设备102向用户设备101发送PDCCH的配置信息，所述PDCCH的配置信息用于指示第一时频资源，所述第一时频资源用于发送PDCCH，且位于多时隙组中的多个连续的时域单元中。
用户设备101从网络设备102接收PDCCH的配置信息，所述PDCCH的配置信息用于指示第一时频资源，所述第一时频资源用于发送PDCCH，且位于多时隙组中的多个连续的时域单元中。
其中，所述第一时频资源在所述多时隙组的时频资源中占用的时域单元的最大数量与所述多时隙组的时频资源包括的时域单元的数量相关。
在一实施方式中，第一时频资源在所述多时隙组的时频资源中占用的时域单元的最大数量与多时隙组的时频资源包括的时域单元的数量呈正相关，即，第一时频资源在所述多时隙组的时频资源中占用的时域单元的最大数量越大，多时隙组的时频资源包括的时域单元的数量越大；第一时频资源在所述多时隙组的时频资源中占用的时域单元的最大数量越小，多时隙组的时频资源包括的时域单元的数量越小。
在一示例中：
多时隙组的时频资源包括的时隙的数量是4个，第一时频资源在所述多时隙组的时频资源中占用的时域单元的最大数量是2个。
多时隙组的时频资源包括的时隙的数量是8个，第一时频资源在所述多时隙组的时频资源中占用的时域单元的最大数量是3个。
在一实施方式中，第一时频资源在所述多时隙组的时频资源中占用的时域单元的最大数量与多时隙组的时频资源包括的时域单元的数量呈正比。
在一示例中：
多时隙组的时频资源包括的时隙的数量是4个，第一时频资源在所述多时隙组的时频资源中占用的时域单元的最大数量是2个。
多时隙组的时频资源包括的时隙的数量是8个，第一时频资源在所述多时隙组的时频资源中占用的时域单元的最大数量是4个。
本公开实施例中，使第一时频资源在所述多时隙组的时频资源中占用的时域单元的最大数量与所述多时隙组的时频资源包括的时域单元的数量相关，从而使第一时频资源在所述多时隙组的时频资源中占用的时域单元的最大数量随着时域资源不同的时隙组而相应的调整，使第一时频资源在所述多时隙组的时频资源中占用的时域单元的最大数量的设置方式更智能。

其中，多时隙组的时频资源中占用的时域单元的最大数量与子载波间隔相关时，所述第一时频资源在所述多时隙组的时频资源中占用的时域单元的最大数量与子载波间隔相关。
在一实施方式中，第一时频资源在所述多时隙组的时频资源中占用的时域单元的最大数量与子载波间隔呈正相关。
在一示例中，:
