Abstract

本公开是关于一种物理下行控制信道监测方法、装置及存储介质。物理下行控制信道监测方法包括: 响应于终端需要在重叠的时域位置上监听多个物理下行控制信道，确定一个或多个指定控制资源集和/或一个或多个指定波束信息; 在所述重叠的时域位置上监测所述指定控制资源集的物理下行控制信道，以及波束信息与所述指定控制资源集的波束信息相同的其他控制资源集的物理下行控制信道，或者，在所述重叠的时域位置上监测波束信息与指定波束信息相同的控制资源集的物理下行控制信道。通过本公开可以提高物理下行控制信道接收成功率。

Description

物理下行控制信道监测方法、装置及存储介质 技术领域
本公开涉及通信技术领域，尤其涉及物理下行控制信道监测方法、装置及存储介质。
背景技术
在新无线技术(New Radio，NR)中，例如通信频段在frequency range 2时，由于高频信道衰减较快，为了保证覆盖范围，需要使用基于波束(beam)的发送和接收。
相关技术中，由于考虑终端只能用一个波束来接收网络设备发送的物理下行控制信道(physical downlink control channel，PDCCH)，所以在多个PDCCH候选(PDCCH candidate)对应的监测时域位置(monitor occasion)重叠时，当多个PDCCH candidate对应的控制资源集(Control Resource Set，CORESET)的准共址(quasi-colocation，QCL)波束信息不同时，例如，QCL Type D不同时，那么终端在这个重叠的monitor occasion需要确定一个指定的CORESET，然后使用这个指定的CORESET对应的QCL Type D在这个重叠的monitor occasion监测该指定的CORESET对应的PDCCH以及与该指定的CORESET的QCL Type D相同的其它CORESET对应的PDCCH。
由于在重叠的monitor occasion，终端只能使用一个QCL Type D监测PDCCH，故，终端将无法接收使用不同QCL Type D进行监测的PDCCH，即降低了PDCCH传输成功率。Rel-17中，终端将支持使用多个(典型值为2个)QCL Type D同时接收多个PDCCH，所以在重叠的monitor occasion上，需要确定一个或多个CORESET，让终端使用该一个或多个CORESET对应的一个或多个QCL Type D去监测重叠的monitor occasion上的多个PDCCH。然而，如何确定用于监测PDCCH的一个或多个CORESET，目前没有解决方法。

具体实施方式
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指定。
本公开实施例提供的PDCCH监测方法可应用于图1所示的无线通信系统中。参阅图1所示，该无线通信系统中包括终端和网络设备。终端通过无线资源与网络设备相连接，并进行数据的发送与接收。
可以理解的是，图1所示的无线通信系统仅是进行示意性说明，无线通信系统中还可包括其它网络设备，例如还可以包括核心网设备、无线中继设备和无线回传设备等，在图1中未画出。本公开实施例对该无线通信系统中包括的网络设备数目和终端数目不做限定。
进一步可以理解的是，本公开实施例的无线通信系统，是一种提供无线通信功能的网络。无线通信系统可以采用不同的通信技术，例如码分多址(code division multiple access,CDMA)、宽带码分多址(wideband code division multiple access，WCDMA)、时分多址(time division multiple access，TDMA)、频分多址(frequency division multiple access，FDMA)、正交频分多址(orthogonal frequency-division multiple access，OFDMA)、单载波频分多址(single Carrier FDMA，SC-FDMA)、载波侦听多路访问/冲突避免(Carrier Sense Multiple Access with Collision Avoidance)。根据不同网络的容量、速率、时延等因素可以将网络分为2G(英文：generation)网络、3G网络、4G网络或者未来演进网络，如5G网络，5G网络也可称为是新无线网络(New Radio，NR)。为了方便描述，本公开有时会将无线通信 网络简称为网络。
进一步的，本公开中涉及的网络设备也可以称为无线接入网设备。该无线接入网设备可以是：基站、演进型基站(evolved node B，eNB)、家庭基站、无线保真(wireless fidelity，WIFI)系统中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission point，TP)或者发送接收点(transmission and reception point，TRP)等，还可以为NR系统中的gNB，或者，还可以是构成基站的组件或一部分设备等。当为车联网(V2X)通信系统时，网络设备还可以是车载设备。应理解，本公开的实施例中，对网络设备所采用的具体技术和具体设备形态不做限定。
进一步的，本公开中涉及的终端，也可以称为终端设备、用户设备(User Equipment，UE)、移动台(Mobile Station，MS)、移动终端(Mobile Terminal，MT)等，是一种向用户提供语音和/或数据连通性的设备，例如，终端可以是具有无线连接功能的手持式设备、车载设备等。目前，一些终端的举例为：智能手机(Mobile Phone)、口袋计算机(Pocket Personal Computer，PPC)、掌上电脑、个人数字助理(Personal Digital Assistant，PDA)、笔记本电脑、平板电脑、可穿戴设备、或者车载设备等。此外，当为车联网(V2X)通信系统时，终端设备还可以是车载设备。应理解，本公开实施例对终端所采用的具体技术和具体设备形态不做限定。
本公开中网络设备与终端之间基于波束进行数据传输。在Rel-15/16中，基于波束进行数据传输过程中，终端只能用一个波束来接收网络设备发送的PDCCH，所以在多个PDCCH candidate对应的monitor occasion重叠时，当多个PDCCH candidate对应的CORESET的波束信息不同时，例如，QCL Type D不同时，那么终端在这个重叠的monitor occasion需要确定一个指定的CORESET，然后使用这个指定的CORESET对应的QCL Type D在这个重叠的monitor occasion监测该指定的CORESET对应的PDCCH以及与该指定的CORESET的QCL Type D相同的其它CORESET对应的PDCCH。即，在重叠的monitor occasion，终端只能使用一个QCL Type D监测PDCCH，故，终端将无法接收使用不同QCL Type D进行监测的PDCCH，即降低了PDCCH传输成功率。Rel-17中，终端将支持使用多个(典型值为2个)QCL Type D同时接收多个PDCCH，故，在重叠的monitor occasion上，可以确定一个或多个CORESET，让终端使用该一个或多个CORESET对应的一个或多个QCL Type D去监测重叠的monitor occasion上的多个PDCCH，以提高PDCCH的接收成功率。
本公开实施例提供一种PDCCH监测方法，终端需要在重叠的时域位置上监听多个PDCCH的情况下，确定一个或多个指定CORESET和/或一个或多个指定波束信息，进而 在重叠的时域位置上监测指定CORESET的PDCCH，以及波束信息与指定CORESET的波束信息相同的其他CORESET的PDCCH，或者，在重叠的时域位置上监测波束信息与指定波束信息相同的CORESET的PDCCH，提高PDCCH接收成功率。
本公开实施例中波束信息可以基于传输配置指示状态(transmission configuration indication，TCI state)确定。其中，TCI state中可以指示多种QCL Type，其中包含QCL Type D。为描述方便，以下实施例中以波束信息为QCL Type D为例进行说明，可以理解的是，本公开实施例中波束信息也可以包括其他QCL信息。
其中，终端需要在重叠的时域位置上监听多个PDCCH的情况下，终端在重叠的PDCCH monitoring occasion上需要监听的多个PDCCH candidate对应的CORESET配置的QCL Type D相同或不同。
图2是根据一示例性实施例示出的一种PDCCH监测方法的流程图，如图2所示，PDCCH监测方法包括以下步骤。
在步骤S11中，响应于终端需要在重叠的时域位置上监听多个PDCCH，确定至少一个指定CORESET和/或至少一个指定波束信息。
在步骤S12a中，在重叠的时域位置上监测指定CORESET的PDCCH，以及波束信息与指定CORESET的波束信息相同的其他CORESET的PDCCH。
在步骤S12b中，在重叠的时域位置上监测波束信息与指定波束信息相同的CORESET的PDCCH。
其中，可以理解的是，本公开实施例中S12a和S12b的执行步骤可以是择一执行的，也可以是分别或一起被执行的。
可以理解的是，本公开实施例中确定至少一个指定CORESET可以是确定一个或多个指定CORESET。本公开实施例中确定至少一个指定波束信息可以是确定一个或多个指定波束信息。
进一步可以理解的是，本公开实施例中波束信息与指定CORESET的波束信息相同的其他CORESET，可以是包括其他CORESET的至少一个波束信息与指定CORESET的至少一个波束信息相同的情况，即，选择了指定CORESET的至少一个波束来监测PDCCH。本公开实施例中监测波束信息与指定波束信息相同的CORESET的PDCCH，可以是包括CORESET的至少一个波束信息与至少一个指定波束信息相同。
即，本公开实施例中可以在重叠的时域位置上监测指定CORESET的PDCCH，以及波束信息与指定CORESET的至少一个波束信息相同的其他CORESET的PDCCH。或者在重叠的时域位置上监测波束信息与至少一个指定波束信息相同的CORESET的PDCCH。
本公开实施例提供的PDCCH监测方法中，一方面，指定的CORESET可能为一个CORESET，该一个CORESET可以是被配置了一个或多个TCI state的CORESET。另一方面，指定的CORESET可能为多个CORESET，多个CORESET中的每一CORESET被配置一个或多个TCI state。
本公开实施例提供的PDCCH监测方法中，指定的波束信息可以是指定的CORESET对应的至少一个QCL Type D。
本公开实施例提供的PDCCH监测方法中，终端可以是被配置一个或多个服务小区(serving cell)。每一serving cell对应有服务小区索引(serving cell index)。
本公开实施例提供的PDCCH监测方法中，终端在重叠的PDCCH monitoring occasion上需要监听的多个PDCCH candidate对应的CORESET可以被配置有通用搜索空间集(Common Search space set，CSS set)。CSS set对应有CSS set索引(CSS set index)。
本公开实施例提供的PDCCH监测方法中，终端在重叠的PDCCH monitoring occasion上需要监听的多个PDCCH candidate对应的CORESET可以被配置有终端特定搜索空间集(UE-specific Search space set，USS set)。USS set对应有USS set索引(USS set index)。
本公开实施例的一种实施方式中，确定一个或多个指定CORESET或一个或多个指定波束信息时，可以基于如下至少一种信息确定一个和/或多个指定CORESET和/或一个或多个指定波束信息：
重叠的时域位置上需要监听的多个PDCCH候选对应的CORESET的服务小区索引；重叠的时域位置上需要监听的多个PDCCH候选对应的CORESET是否包含CSS set；重叠的时域位置上需要监听的多个PDCCH候选对应的CORESET包含的CSS set的索引；重叠的时域位置上需要监听的多个PDCCH候选对应的CORESET的USS set的索引；重叠的时域位置上需要监听的多个PDCCH候选对应的CORESET配置的TCI state的数量。
一种实施方式中，本公开实施例中可以基于服务小区索引、是否包含CSS set、CSS set的索引、USS set的索引以及TCI state的数量中的至少一项，在重叠的时域位置上需要监听的多个PDCCH候选对应的CORESET中确定一个或多个指定CORESET，和/或将指定CORESET的波束信息确定为一个或多个指定波束信息。
图3是根据一示例性实施例示出的一种PDCCH监测方法的流程图，该PDCCH监测方法可以单独被执行，也可以结合本公开的其他实施例一起被执行。如图3所示，PDCCH监测方法包括以下步骤。
在步骤S21中，在重叠的时域位置上需要监听的多个PDCCH候选对应的CORESET中，选择包含有CSS set的CORESET。
在步骤S22中，在包含有CSS set的CORESET的服务小区中，选择服务小区索引最小的服务小区。
在步骤S23中，确定服务小区索引最小的服务小区中CSS set索引最小的CSS set，并将该搜索空间集索引最小的CSS set对应的CORESET确定为指定CORESET，和/或将该搜索空间集索引最小的CSS set对应的CORESET的至少一个波束信息确定为指定波束信息。
本公开实施例提供的PDCCH监测方法中，可以基于服务小区索引、是否包含CSS set、CSS set的索引、USS set的索引以及TCI state的数量中的至少一项，确定重叠的时域位置上需要监听的多个PDCCH候选对应的CORESET的优先级或者搜索空间的优先级。基于CORESET的优先级或者搜索空间的优先级，在多个PDCCH候选中确定指定CORESET，和/或将指定CORESET的波束信息确定为指定波束信息。
一示例中，假设在重叠的monitor occasion上有CSS set#0，CSS set#1，USS set#2，USS set#3，并满足如下条件1：
i.CSS set#0对应CORESET#0，serving cell#0，
ii.CSS set#1对应CORESET#1，serving cell#0，
iii.USS set#2对应CORESET#2，serving cell#1，
iv.USS set#3对应CORESET#3，serving cell#1，
故，针对上述条件1，优先级大小为CORESET#0>CORESET#1>CORESET#2>CORESET#3或者也可以理解为是CSS set#0>CSS set#1>USS set#2>USS set#3。
在选择CORESET或选择QCL Type D时，可以按照基于上述条件1确定的优先级顺序来选择。当每个CORESET对应一个TCI state时，CORESET的优先级跟搜索空间的优先级一样。
另一示例中，假设在重叠的monitor occasion上有CSS set#0，CSS set#1，USS set#2，USS set#3，并满足如下条件2：
i.CSS set#0对应CORESET#0，serving cell#0，
ii.CSS set#1对应CORESET#0，serving cell#0，
iii.USS set#2对应CORESET#1，serving cell#1，
iv.USS set#3对应CORESET#2，serving cell#1，
其中，针对上述条件2，优先级大小为CORESET#0CSS set#0>CORESET#0CSS set#1>CORESET#1>CORESET#2或者也可以理解为是CSS set#0>CSS set#1>USS set#2>USS set#3。
在选择CORESET或选择QCL Type D时，按照基于上述条件2确定的优先级顺序来选择。这里由于CSS set#0和CSS set#1对应同一个CORESET#0且对应不同的TCI state时，所以实际上是按照搜索空间集的优先级来确定CORESET或者确定QCL Type D。即当CORESET#0对应多个TCI state时，选择CSS set#0对应的TCI state来确定QCL Type D。
本公开实施例提供的PDCCH监测方法中，在进行指定CORESET或者指定QCL Type D确定时，若所有CORESET都没有CSS时，可以基于USS确定。例如，可以选择USS set的serving cell index最小的小区中USS set index最小的USS set对应的CORESET。
图4是根据一示例性实施例示出的一种PDCCH监测方法的流程图，该PDCCH监测方法可以单独被执行，也可以结合本公开的其他实施例一起被执行。如图4所示，PDCCH监测方法包括以下步骤。
在步骤S31中，在重叠的时域位置上需要监听的多个PDCCH候选对应的CORESET中，选择包含有USS set的CORESET。
在步骤S32中，在包含有USS set的CORESET的服务小区中，选择服务小区索引最小的服务小区。
在步骤S33中，确定服务小区索引最小的服务小区中USS set索引最小的USS set，并将该USS set对应的CORESET确定为指定CORESET，和/或将该搜索空间集索引最小的USS set对应的CORESET的至少一个波束信息确定为指定波束信息。
可以理解的是，本公开实施例上述图3和图4所示的CORESET和/或QCL Type D确定时，基于服务小区索引最小且搜索空间集索引最小的CSS set，或者选择服务小区索引最小且搜索空间集索引最小的USS set，进行CORESET和/或QCL Type D确定，仅是进行示意性说明。本公开实施例还可以采用其他方式，例如，基于服务小区索引最大和/或搜索空间集索引最大的CSS set，或者选择服务小区索引最大和/或搜索空间集索引最大的USS set，进行CORESET和/或QCL Type D确定。
一种实施方式中，本公开实施例提供的PDCCH监测方法中，指定的CORESET可以包括一个或多个CORESET。
其中，一个或多个指定CORESET中的每一CORESET配置有一个或多个TCI state。
一种实施方式中，本公开实施例中可以确定多个指定CORESET，多个指定CORESET中的每个指定CORESET配置了一个或多个TCI state。
图5是根据一示例性实施例示出的一种PDCCH监测方法的流程图，该PDCCH监测方法可以单独被执行，也可以结合本公开的其他实施例一起被执行。如图5所示，PDCCH监测方法中确定指定CORESET的过程包括以下步骤。
在步骤S41中，确定多个指定CORESET，多个指定CORESET中的每个指定CORESET配置了一个或多个TCI state。
本公开实施例中，假设确定的指定CORESET每个指定CORESET配置了一个或多个TCI state，针对每个指定CORESET确定了其中一个指定TCI state，确定方法可以基于本公开任一实施例中搜索空间集优先级最高的搜索空间集对应的TCI state来确定，在重叠的时域位置上监测多个指定CORESET的PDCCH，以及与多个指定CORESET对应的多个指定TCI state对应的至少一个波束信息相同的其他CORESET的PDCCH。
另一种实施方式中，本公开实施例中可以确定一个指定CORESET，一个指定CORESET可配置多个TCI state。
图6是根据一示例性实施例示出的一种PDCCH监测方法的流程图，该PDCCH监测方法可以单独被执行，也可以结合本公开的其他实施例一起被执行。如图6所示，PDCCH监测方法中确定指定CORESET的过程包括以下步骤。
在步骤S51中，确定一个指定CORESET，一个指定CORESET配置了多个TCI state。
本公开实施例中，假设确定的指定CORESET为一个指定CORESET，该一个指定CORESET配置了多个TCI state，可以确定其中一个指定TCI state，确定方法可以基于本公开任一实施例中搜索空间集优先级最高的搜索空间集对应的TCI state来确定，在重叠的时域位置上监测指定CORESET的PDCCH，以及与指定CORESET对应的多个指定TCI state对应的至少一个波束信息相同的其他CORESET的PDCCH。
本公开实施例中，假设确定的指定CORESET中包括第一指定的CORESET，可以基于第一指定的CORESET的TCI state配置情况确定是否还包括其他CORESET(以下称为第二指定的CORESET)。
一示例中，第一指定的CORESET为只配置了一个TCI state的CORESET时，需要确定第二指定的CORESET。即，指定CORESET包括配置了一个TCI state的第一指定CORESET，在所述重叠的时域位置上监测所述第一指定CORESET以及第二指定CORESET的PDCCH，以及与所述第一指定CORESET和/或与所述第二指定CORESET的至少一个TCI state对应的波束信息相同的其他CORESET的PDCCH。
另一示例中，第一指定的CORESET为配置了两个TCI state的CORESET时，若确定的优先级最高的CSS set对应了两个TCI state，则无需确定第二指定的CORESET。即，指定CORESET包括配置了多个TCI state的第一指定CORESET，且所述第一指定CORESET的通用搜索空间集对应多个TCI state，在所述重叠的时域位置上监测所述第一指定CORESET的PDCCH，以及波束信息与所述第一指定CORESET所配置的多个TCI state 对应的至少一个波束信息相同的其他CORESET的PDCCH。
又一示例中，第一指定的CORESET为配置了两个TCI state的CORESET时，若确定的优先级最高的CSS set对应了其中一个TCI state，则需要确定第二指定的CORESET。即，指定CORESET包括配置了多个TCI state的第一指定CORESET，且所述第一指定CORESET的CSS set对应一个TCI state，则将该CSS set对应的一个TCI state对应的波束信息确定为第一指定波束信息，在所述重叠的时域位置上监测所述第一指定CORESET以及第二指定CORESET的PDCCH，以及与所述第一指定CORESET的TCI state对应的第一指定波束信息或与所述第二指定CORESET的至少一个TCI state对应的波束信息相同的其他CORESET的PDCCH。
本公开实施例中，若确定多个指定CORESET，则多个指定CORESET之间满足如下条件中的至少一个：
A)、多个指定CORESET分别对应不同的发送接收点。
B)、多个指定CORESET对应不同的控制资源池索引(CORESET Pool Index)。
C)、多个指定CORESET对应不同的物理小区标识。
D)、多个指定CORESET对应的波束为终端能够同时接收的波束，和/或为终端不同面板接收的波束。
一种实施方式中，多个指定波束信息对应的波束为终端能够同时接收的波束，和/或为终端不同面板接收的波束。
基于上述限定条件，本公开实施例中，多个CORESET包括第一指定的CORESET和第二指定的CORESET的情况下，即上述实施例中涉及的需要进行第二指定的CORESET选择的情况，在第一指定的CORESET选择出来后，可以在除了第一指定CORESET之外的其它CORESET中选择第二指定的CORESET。其中，第二指定的CORESET的选择方法可以同第一指定CORESET一样。或者第二指定的CORESET的选择方法可以同第一指定CORESET不一样。一示例中，本公开实施例中第二CORESET为包含USS set的serving cell index最小的cell中USS set index最小的USS set对应的CORESET(因为可能第一CORESET已经包含CSS set了，第二CORESET即从USS set中确定即可)。但是第二指定CORESET只能选择一个TCI state对应的QCL Type D(即使第二指定CORESET被配置了两个TCI state)。
本公开实施例提供的PDCCH监测方法中，确定指定CORESET后，可以基于指定CORESET配置的TCI state确定一个或多个指定波束信息。
一种实施方式中，本公开实施例中可以基于指定CORESET配置的TCI state确定多个 指定波束信息。
图7是根据一示例性实施例示出的一种PDCCH监测方法的流程图，该PDCCH监测方法可以单独被执行，也可以结合本公开的其他实施例一起被执行。如图7所示，PDCCH监测方法中确定指定波束信息的过程包括以下步骤。
在步骤S61中，根据多个指定CORESET中的每个指定CORESET的至少一个TCI state确定多个指定波束信息。
本公开实施例中，当某个CORESET配置了多个TCI state时，可以选择其中一个TCI state确定一个指定波束方向，选择的方法可以依据本发明任一实施例中所述优先级最高的搜索空间集对应的TCI state。
一种实施方式中，本公开实施例中可以基于指定CORESET配置的TCI state确定一个指定波束信息。
图8是根据一示例性实施例示出的一种PDCCH监测方法的流程图，该PDCCH监测方法可以单独被执行，也可以结合本公开的其他实施例一起被执行。如图8所示，PDCCH监测方法中确定指定波束信息的过程包括以下步骤。
在步骤S71中，根据一个指定CORESET的多个TCI state确定多个指定波束信息。
当指定CORESET配置了多个TCI state时，可以将多个TCI state对应的波束信息确定为多个指定波束信息。多个TCI state可以对应相同的或不同的搜索空间集。
本公开实施例提供的PDCCH监测方法中，多个指定波束信息对应的波束为终端能够同时接收的波束，和/或为所述终端不同面板接收的波束。
本公开实施例提供的PDCCH监测方法中，确定多个PDCCH candidate在monitor occasion重叠时，确定一个或多个CORESET对应的一个或多个QCL Type D，去monitor重叠occasion上的PDCCH，能够提高PDCCH接收成功率。
需要说明的是，本领域内技术人员可以理解，本公开实施例上述涉及的各种实施方式/实施例中可以配合前述的实施例使用，也可以是独立使用。无论是单独使用还是配合前述的实施例一起使用，其实现原理类似。本公开实施中，部分实施例中是以一起使用的实施方式进行说明的。当然，本领域内技术人员可以理解，这样的举例说明并非对本公开实施例的限定。
