本申请实施例公开了物理下行控制信道(physical downlink control channel,PDCCH)的监控方法、装置、用户设备及存储介质,在用户设备(user equipment,UE)的PDCCH监控时刻,如果存在至少两个搜索空间(search space,SS),该至少两个搜索空间关联至少两个控制资源集(Control resource set,CORESET),可以从该至少两个CORESET中选择两种不同准共址类型D(Quasi co-location type D,QCL-TypeD)属性的第一类CORESET和第二类CORESET中监控需要接收的PDCCH。为了更好理解本申请实施例公开的PDCCH的监控方法、装置、用户设备及存储介质,下面先对本申请实施例适用的网络构架进行描述。本申请实施例公开的方法可以应用于5G新无线接入技术(New RAT(radio access technology),NR)系统,也可以应用于其它通信系统,只要该通信系统中存在需要接收PDCCH的场景。下面先介绍本申请实施例公开的方法所适用的一种网络架构。
请参阅图1,图1是本申请实施例提供的一种网络构架示意图。该网络构架适用于需要接收PDCCH的场景,具体可以为:在UE的PDCCH监控时刻,如果存在至少两个搜索空间,该至少两个搜索空间关联至少两个CORESET,可以从该至少两个CORESET中选择两种不同准共址类型D属性的第一类CORESET和第二类CORESET中监控需要接收的PDCCH。网络设备是网络侧的一种用于发射或接收信号的实体,如gNB。用户设备是用户侧的一种用于接收或发射信号的实体,如手机。由于基站和UE的应用场景较多,下面以基站作为网络设备的示例,以通讯系统为NR系统为例。如图1所示,该网络架构包括基站(base station)和UE(如图1中的用户设备1、用户设备2或用户设备3)。在NR系统 中,基站可以给UE配置多个控制资源集(Control resource set,CORESET)。在NR系统中,UE要知道PDCCH在频域上的位置和时域上的位置才能成功解码PDCCH。为了方便,NR系统将PDCCH频域上占据的频段和时域上占用的正交频分复用(orthogonal frequency division multiplexing,OFDM)符号数等信息封装在CORESET中;将PDCCH起始OFDM符号编号以及PDCCH监测周期等信息封装在搜索空间(search space,SS)中。UE需要选择合适的CORESET候选,并在CORESET候选中监控PDCCH。
在现有协议中,在某一的PDCCH监控时刻,若关联的多个CORESET有不同的QCL-TypeD属性(QCL-TypeD properties)时,UE按照一定的优先级准则进行监控PDCCH。现有协议假设终端只能监听一个QCL-TypeD属性相关的PDCCH。而在NR Rel-17中立项明确支持终端multi-panel/multi-trp部署且同时接收,也即支持UE在某一监听时刻,可以监听多于1个QCL-TypeD属性相关的PDCCH。本申请实施例设计了一种在UE在某一监听时刻,可以监听多于1个QCL-TypeD属性相关的PDCCH的方案。
下面来详细描述本申请实施例提供的PDCCH的监控方法。
请参阅图2,图2是本申请实施例提供的一种PDCCH的监控方法的流程示意图。如图2所示,该PDCCH的监控方法可以包括如下步骤。
201,在用户设备UE的物理下行控制信道PDCCH监控时刻,存在至少两个搜索空间,该至少两个搜索空间关联至少两个控制资源集CORESET,若UE没有配置CORESET索引池,或者UE配置包括CORESET索引池取值为0的第一CORESET集合和CORESET索引池取值为1的第二CORESET集合;UE在第一类CORESET和第二类CORESET中监控PDCCH,该第一类CORESET的准共址类型D属性为第一类型,该第二类CORESET的准共址类型D属性为第二类型,第一类型与第二类型不同。
本申请实施例中,一个搜索空间只能关联一个CORESET,一个CORESET所关联的搜索空间的数量可以是至少一个。搜索空间的类型包括公共搜索空间(Common search space,CSS)、用户专用搜索空间(UE-specific search space,USS)。CSS用于广播控制信道(broadcast control channel,BCCH)、寻呼、RAR等相关的控制信息(小区级公共信息)。USS用于传输与下行共享信道(downlink shared channel,DL-SCH)、(uplink shared channel,UL-SCH)等相关的控制信息(UE级信息)。其中,两个搜索空间可以重叠。
CORESET位于部分带宽(bandwidth part,BWP)内,对于每个BWP,最多可被配置3个CORESET。BWP定义为一个载波内连续的多个资源块(resource block,RB)的组合。
准共址定义如下:如果某天线端口符号上的信道特性可以从另一个天线端口推导出,则认为这两个端口准共址(Quasi co-location,QCL),从一个端口获得的信道估计结果,可以用于另一个端口。QCL信息可以通过高层配置。
CORESET的准共址(Quasi co-location,QCL)类型可以包括准共址类型A(QCL-TypeA),或准共址类型B(QCL-TypeB),或准共址类型C(QCL-TypeC)或准共址类型D(QCL-TypeD)中的至少一种。
对于QCL-TypeA,其准共址参数包括:多普勒频移、多普勒扩展、平均时延和时延扩展。对于QCL-TypeB,其准共址参数包括:多普勒频移和多普勒扩展。对于QCL-TypeC,其准共址参数包括:平均时延和多普勒频移。对于QCL-TypeD,其准共址参数包括:空间接收参数(Spatial Rx parameter);用于辅助UE接收和/或者发送。
在NR系统中,为了提高系统或者UE性能,可以采用多个发送接收点(Transmission Reception point,TRP)进行数据传输。CORESET索引池(CORESETPoolIndex)取值是用来区分哪些CORESET属于同一个TRP。比如,CORESET索引池取值为0的第一CORESET集合属于第一TRP,CORESET索引池取值为2的第二CORESET集合属于第二TRP。
如果网络设备为UE配置了CORESET索引池,也即,UE被提供CORESET索引池, 并且配置的两个CORESET索引池的取值分别为0和1。则UE会在CORESET索引池取值为0的第一CORESET集合和/或CORESET索引池取值为2的第二CORESET集合中监控PDCCH。
本申请实施例中,对于多发送接收节点(Multi-TRP)的传输技术,可以在两个不同TRP对应的两个准共址类型D属性不同的CORESET集合中同时监控PDCCH。
如果网络设备没有为UE配置CORESET索引池,也即,UE没有被提供CORESET索引池,则UE在第一类CORESET和第二类CORESET中监控PDCCH。其中,该第一类CORESET的准共址类型D属性与第二类CORESET的准共址类型D属性不同。
本申请实施例中,在UE的PDCCH监控时刻,如果存在至少两个搜索空间,该至少两个搜索空间关联至少两个CORESET,可以从该至少两个CORESET中选择两种不同准共址类型D属性的第一类CORESET和第二类CORESET中监控需要接收的PDCCH。可以在至少两个搜索空间关联的至少两个不同准共址类型D属性的CORESET中监控需要接收的PDCCH。
其中,所述第一类CORESET可以属于所述至少两个CORESET,所述第二类CORESET可以属于所述至少两个CORESET。
可选的,所述至少两个CORESET中存在两个CORESET的准共址类型D属性不同。
可选的,所述至少两个搜索空间之间重叠。
可选的,上述步骤201中,UE在第一类CORESET和第二类CORESET中监控PDCCH,包括:
UE确定第一CORESET集合中的第一CORESET以及第一CORESET集合中与该第一CORESET的准共址类型D属性相同的CORESET为第一类CORESET,UE确定第二CORESET集合中的第二CORESET以及第二CORESET集合中与该第二CORESET的准共址类型D属性相同的CORESET为第二类CORESET;该第一类CORESET的准共址类型D属性为第一类型,该第二类CORESET的准共址类型D属性为第二类型,第一类型与第二类型不同;UE在第一类CORESET和第二类CORESET中监控PDCCH。
