Description

确定时隙个数、位置、多时隙组时长的方法、装置及介质 技术领域
本公开涉及无线通信技术领域，尤其涉及一种确定时隙个数、位置、多时隙组时长的方法、装置及介质。
背景技术
在无线通信协议中，第五代移动通信技术(5th Generation Mobile Communication Technology，5G)的新空口(New Radio，NR)通信协议中，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。基站设备通过承载在物理下行控制信道(physical downlink control channel，PDCCH)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(UE-specific search space，USS)。CSS用于承载小区公共控制信息、组播控制信息、UE特定的控制信息等，USS用于承载UE特定的控制信息。
当用户设备(User Equipment，UE)处于无线资源控制(Radio Resource Control，RRC)空闲态(idle)时需要监听Type #0 CSS。用户设备101处于RRC空闲态时所监听的Type #0CSS所在时隙满足：根据同步信号块(SSB)或者控制资源集(ControlResourceSet，CORESET)的多路复用模式1(multiplexing pattern 1)下的Type #0 CSS所在的系统帧号(system frame number，SFN)，确定Type #0 CSS的时隙。其中，Type #0 CSS所在的SFN以20ms为周期，在该SFN中，Type #0 CSS在时隙(slot)n0和slot n0+1上，n0的数值根据3GPP协议TS 38.213中的计算公式确定。
在高频段(例如60GHz左右)，为了应对相位噪声，通常会选取较大的子载波带宽。较大的子载波间隔(SubCarrier Spacing，SCS)对应着较小的时隙(slot)时长。例如：SCS对应于960KHz的情况下，一个时隙的持续时间长度为0.015625毫秒即1/64毫秒。在这种情况下，终端可能不需要在每个时隙(slot)都盲检物理下行控制信道(Physical Downlink Control Channel，PDCCH)，从而引入了多时隙组PDCCH监听能力(multi-slot group PDCCH monitoring capability)，即PDCCH监听能力按照X个时隙的多时隙组为时间单位进行定义，其中X是一个多时隙组包含的时隙的总数。
因此，需要研究上述多时隙组包含的时隙总数X的确定方式。

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，本公开实施例提供的一种确定时隙个数、位置、多时隙组时长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但不限于网络设备102和用户设备101。用户设备101被配置为支持载波聚合，用户设备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，也可适用于高频场景。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。
以上所示用户设备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、终端代理或用户设备等。该用户设备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102进行通信(如无线通信)，并接受网络设备102提供的网络服务，这里的网络设备102包括但不限于图示基站。
其中，用户设备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网络中的用户设备或者未来演进的PLMN网络中的用户设备等。
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。网络设备具体可包括基站(base station，BS)设备，或包括基站设备以及用于控制基站设备的无线资源管理设备等。该网络设备还可包括中继站(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。网络设备可以是可穿戴设备或车载设备。网络设备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。
处于空闲态的用户设备101涉及多时隙组PDCCH监听能力(multi-slot group PDCCH monitoring capability)，该监听能力中可按照包含X个时隙的多时隙组为时间单位进行定义。 从而，可以使Type #0 CSS在slot n0和slot n0+X中传输，X为多时隙组包含的时隙总量，从而可以将Type #0 CSS分散在两个多时隙组中，避免Type #0 CSS的2个时隙都位于同一个多时隙组中，导致用户设备将一个多时隙组中的盲检能力过多的消耗在Type #0 CSS的监听上。
不同信道所对应的子载波间隔可能不同。例如，SSB、Type #0 CSS PDCCH信道，以及UE在连接态下的PDCCH信道和PDSCH信道，对应的子载波间隔不同。因此，需要确定Type #0 CSS所在时隙n0+X中X值、或者监听能力中多时隙组的X值。
本公开实施例中提供了一种确定物理下行控制信道PDCCH时域位置的方法，图2是根据一示例性实施例示出的一种确定PDCCH时域位置的方法的流程图，如图2所示，该方法包括：
步骤S201、用户设备101基于预设信道的子载波间隔SCS确定第一值X；其中，第一值X为第二类型组搜索空间Group(2)SS对应的一个多时隙组包括的时隙总数。
步骤S202-1、用户设备101确定第二类型组搜索空间Group(2)SS对应的多时隙组的时长为单时隙时长与第一值X的乘积。
在一示例中，单时隙时长可以为Type#0 CSS信道的子载波间隔SCS对应的单个时隙的时长。
步骤S202-2、用户设备101确定Type#0 CSS所在的时隙包括时隙n0+X。
在一示例中，用户设备101确定Type#0 CSS所在的时隙为时隙n0和时隙n0+X。
步骤S203、向网络设备102发送监听能力，其中，监听能力包括：用户设备101在连接态时在一个多时隙组中监听最多1个Type#0 CSS监听时机。
步骤S204、网络设备102接收用户设备101发送的监听能力。
在一可能的实施方式中，第二类型组搜索空间即Group(2)SS包括Type#0 CSS、Type #0ACSS、Type# 1CSS、Type #2 CSS。
应理解，在以上实施例中，上述方法在步骤S201之后不必包括步骤S202-1和步骤S202-2两者，在一种实施例中，在步骤S201之后，所述方法可以仅包括步骤S202-1，在一种实施方式中，在步骤S201之后，所述方法可以仅包括步骤S202-2。本公开实施例中，用户设备101根据自身所处的不同状态，确定相对应的多时隙组的时隙个数。以便于用户设备可以根据多时隙组的时隙个数，确定多时隙组对应的时长、以及Type#0 CSS所在的时隙，有利于确定PDCCH的时域位置，从而确定PDCCH的检测时机。
