请参考图1,其示出了本公开实施例提供的一种无线通信***的结构示意图。如图1所示,无线通信***是基于移动通信技术的通信***,该无线通信***可以包括:若干个用户设备110以及若干个基站120。
其中,用户设备110可以是指向用户提供语音和/或数据连通性的设备。用户设备110可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网进行通信,用户设备110可以是物联网用户设备,如传感器设备、移动电话和具有物联网用户设备的计算机,例如,可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如,站(Station,STA)、订户单元(subscriber unit)、订户站(subscriber station),移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点、远程用户设备(remote terminal)、接入用户设备(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户设备(user equipment)。或者,用户设备110也可以是无人飞行器的设备。或者,用户设备110也可以是车载设备,比如,可以是具有无线通信功能的行车电脑,或者是外接行车电脑的无线用户设备。或者,用户设备110也可以是路边设备,比如,可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。
基站120可以是无线通信***中的网络侧设备。其中,该无线通信***可以是***移动通信技术(the 4th generation mobile communication,4G)***,又称长期演进(Long Term Evolution,LTE)***;或者,该无线通信***也可以是5G***,又称新空口***或5G NR***。或者,该无线通信***也可以是5G***的再下一代***。其中,5G***中的接入网可以称为NG-RAN(New Generation-Radio Access Network,新一代无线接入网)。
其中,基站120可以是4G***中采用的演进型基站(eNB)。或者,基站120也可以是5G***中采用集中分布式架构的基站(gNB)。当基站120采用集中分布式架构时,通常包括集中单元(central unit,CU)和至少两个分布单元(distributed unit,DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol,PDCP)层、无线链路层控制协议(Radio Link Control,RLC)层、媒体访问控制(Media Access Control,MAC)层的协议栈;分布单元中设置有物理(Physical,PHY)层协议栈,本公开实施例对基站120的具体实现方式不加以限定。
基站120和用户设备110之间可以通过无线空口建立无线连接。在不同的实施方式中,该无线空口是基于***移动通信网络技术(4G)标准的无线空口;或者,该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口,比如该无线空口是新空口;或者,该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。
在一些实施例中,用户设备110之间还可以建立E2E(End to End,端到端)连接。比如车联网通信(vehicle to everything,V2X)中的V2V(vehicle to vehicle,车对车)通信、V2I(vehicle to Infrastructure,车对路边设备)通信和V2P(vehicle to pedestrian,车对人)通信等场景。
这里,上述用户设备可认为是下面实施例的终端设备。
在一些实施例中,上述无线通信***还可以包含网络管理设备130。
若干个基站120分别与网络管理设备130相连。其中,网络管理设备130可以是无线通信***中的核心网设备,比如,该网络管理设备130可以是演进的数据分组核心网(Evolved Packet Core,EPC)中的移动性管理实体(Mobility Management Entity,MME)。或者,该网络管理设备也可以是其它的核心网设备,比如服务网关(Serving GateWay,SGW)、公用数据网网关(Public Data Network GateWay,PGW)、策略与计费规则功能单元(Policy and Charging Rules Function,PCRF)或者归属签约用户服务器(Home Subscriber Server,HSS)等。对于网络管理设备130的实现形态,本公开实施例不做限定。
为了便于本领域内技术人员理解,本公开实施例列举了多个实施方式以对本公开实施例的技术方案进行清晰地说明。当然,本领域内技术人员可以理解,本公开实施例提供的多个实施例,可以被单独执行,也可以与本公开实施例中其他实施例的方法结合后一起被执行,还可以单独或结合后与其他相关技术中的一些方法一起被执行;本公开实施例并不对此作出限定。
为了更好地理解本公开任一个实施例所描述的技术方案,首先,对相关技术中的应用场景进行说明:
在一个实施例中,引入了PDCCH自适应方案,请参见图2,可以动态切换搜索空间组,即基站为终端配置多套搜索空间组SSSG,一个空间组可以包含一个或者多个搜索空间,并动态地指示搜索空间的切换。不同的搜索空间集合可以有不同的周期、频域宽度、PDCCH候选数量、待监听下行控制信息 (DCI,Downlink Control Information)格式等配置。因而终端在监听不同的搜索空间集合时,会有不同的能耗。例如,在数据传输需求较小时,终端切换到周期更长的搜索空间集合,在两个周期点之间,还可以切换到睡眠状态,故可以实现终端侧节能。请参见图3,可以动态跳过PDCCH监听,即基站动态地指示终端在某段时间内不需要监听的PDCCH信道。在该段时间内,终端可以进入睡眠状态,因而可以实现终端节能。
在一个实施例中,在统一的动态PDCCH监听自适应架构中,基站下发PDCCH指示,让终端切换SSSG和/或者跳过PDCCH监听。
对于终端有多个服务小区的情况,在某个服务小区上发送的PDCCH监听自适应指令仅仅只能应用于该服务小区,而不能应用于其他服务小区。
需要说明的是,该方式不能适用于载波聚合场景。但是在XR业务中,由于业务量较大,需要经常使用载波聚合进行数据传输。因此需要考虑新的方案。
如图4所示,本实施例中提供一种PDCCH监听的指示方法,其中,所述方法由接入网设备执行,所述方法包括:
步骤41、向终端发送指示信息;
其中,所述指示信息用于指示以下至少之一:
切换载波聚合CA中第一载波的搜索空间或者搜索空间组;
切换CA中第一载波组的搜索空间或者搜索空间组;以及
跳过CA中第一载波的物理下行控制信道PDCCH监听。
这里,本公开所涉及的所述终端可以是但不限于是手机、可穿戴设备、车载终端、路侧单元(RSU,Road Side Unit)、智能家居终端、工业用传感设备和/或医疗设备等。在一些实施例中,该终端可以是Redcap终端或者预定版本的新空口NR终端(例如,R17的NR终端)。
本公开中涉及的接入网设备可以是基站,所述基站可以为各种类型的基站,例如,第三代移动通信(3G)网络的基站、***移动通信(4G)网络的基站、第五代移动通信(5G)网络的基站或其它演进型基站。

在一个实施例中,第一载波或者第一载波组中的载波被激活时,第一激活BWP上运行的第一搜索空间或者搜索空间组初始状态为协议预先预定或者网络配置;
在一个实施例中,第一载波或者第一载波组中的载波被激活时,第一激活BWP上运行的第一搜索空间或者搜索空间组初始为失效状态,即此时不进行PDCCH的监听。
在一个实施例中,指示信息指示终端进行PDCCH的监听搜索空间的指令用于目标载波或者目标载波组(第一载波或者第一载波组(可以有多个))进行搜索空间或者搜索空间组进行状态变更,比如,从失效状态切换至生效状态,即从不监听PDCCH切换至监听PDCCH。
在一个实施例中,扩展现有的PDCCH自适应指示,即增加搜索空间或者搜索空间组的状态变更指示,比如,用指示位“0”指示休眠搜索空间或者搜索空间组;而指示位“1”则用于唤醒搜索空间或者搜索空间组。
