Description

小区切换方法和设备
交叉引用
本申请要求在2020年02月12日提交中国专利局、申请号为202010089400.X、发明名称为“小区切换方法和设备”的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及通信领域，尤其涉及一种小区切换方法和设备。
背景技术
小区切换大多是通过终端设备协助的方式进行的，例如，网络设备根据终端设备上报的测量报告选择目标小区进行切换。
相关技术中小区切换的流程如下：1、源小区指示切换，并传递切换请求至目标小区；2、目标小区进行许可控制，并提供无线资源控制(Radio Resource Control，RRC)配置，作为切换认可的一部分发送给源小区；3、源小区给终端设备发送RRC重配消息，包括切换命令；4、终端设备将RRC连接至目标小区，并回复切换完成。
可以看出，在进行小区切换时需要网络设备发送RRC重配消息显式地指示终端设备进行切换，时延较长，不够灵活。

具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请具体实施例及相应的附图对本申请技术方案进行清楚、完整地描述。显然，所描述的实施例仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。本说明书各个实施例中的“和/或”表示前后两者的至少之一。
应理解，本申请实施例的技术方案可以应用于各种通信系统，例如：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)、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)或全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信系统、5G系统，或者说新无线(New Radio，NR)系统，或者为后续演进通信系统。
在本申请实施例中，终端设备可以包括但不限于移动台(Mobile Station，MS)、移动终端(Mobile Terminal)、移动电话(Mobile Telephone)、用户设备(User Equipment，UE)、手机(handset)及便携设备(portable equipment)、车辆(vehicle)等，该终端设备可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，例如，终端设备可以是移动电话(或称为“蜂窝”电话)、具有无线通信功能的计算机等，终端设备还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置。
本申请实施例中，网络设备是一种部署在无线接入网中用以为终端设备提供无线通信功能的装置。所述网络设备可以为基站，所述基站可以包括各种形式的宏基站，微基站，中继站，接入点等。在采用不同的无线接入技术的系统中，具有基站功能的设备的名称可能会有所不同。例如在LTE网络中，称为演进的节点B(Evolved NodeB，eNB或eNodeB)，在第三代(3rd Generation，3G)网络中，称为节点B(Node B)，或者后续演进通信系统中的网络设备等等，然用词并不构成限制。
相关技术中在进行小区切换时需要网络设备发送RRC重配消息显式地指示终端设备进行切换，时延较长，不够灵活。为解决上述技术问题，本申请实施例提供了多种方式隐式地指示终端设备进行小区切换。
控制资源集(Control Resource Set，CORESET)为终端设备的物理下行控制信道(Physical Downlink Control Channel，PDCCH)的配置信息，若某个特定CORESET与另一小区关联，则是一个很好的小区切换命令。除了 CORESET，本申请实施例还给出了其它有效的进行小区切换方案，如发送接收点(Transmission and Reception Panel，TRP)的相关信息与另一小区关联，作为波束参考信息的参考信号(Reference Signal，RS)与另一小区关联，波束指示与另一小区关联等方案等等。
在详细介绍本申请各个实施例之前，首先对本申请实施例中提到的“小区切换”的定义进行说明，本申请各个实施例中提到的切换到目标小区或目标TRP，可以包括如下1)至7)中的之一。
1)锚节点(Anchor Node)切换到目标小区。
2)锚节点不变，在有多个TRP的情况下，非锚节点的TRP关联的小区切换。
本说明书各个实施例中，TRP标识(TRP ID)可以为控制资源集资源池索引(CORESETPoolIndex)，多个TRP意味着CORESETPoolIndex的数值大于0。
3)使用目标小区的配置信息。
该例子中，目标小区的配置信息包括高层配置信息和物理层配置信息，其中：a)高层配置信息包括如下至少之一：小区组配置(CellGroupConfig)；特殊小区配置(SpCellConfig)；同步重配(ReconfigurationWithSync)；服务小区公共配置(ServingCellConfigCommon)；服务小区配置(ServingCellConfig)。
b)物理层配置信息包括如下至少之一：传输配置指示(Transmission Configuration Indication，TCI)信息；准共址(Quasi Co-Location，QCL)信息；路损参考参考信号(PathLossreference RS，PL RS)；随机接入信道(Random Access Channel，RACH)资源；扰码信息。
4)CORESET#0属于目标小区。
5)PDCCH属于目标小区。
6)特殊小区(SpCell，包括主小区和主辅小区)切换到目标小区。
7)控制资源集资源池索引(CORESETPoolIndex)关联的网络节点标识(例如，cell ID)或网络节点相关信息发生变化。具体例如，CORESETPoolIndex关联的cell ID或cell ID的相关信息发生变化。
需要说明的是，本申请各个实施例中提到的网络节点可以是小区或TRP。
以下将分多个实施例，对本申请提供的小区切换方法进行详细说明。
如图1所示，本申请的一个实施例提供一种小区切换方法100，该方法可以由终端设备执行，换言之，该方法可以由安装在终端设备的软件或硬件来执行，该方法包括如下步骤：
S102：在满足下述至少之一的情况下，切换至目标小区或目标TRP：1)第一CORESET与目标小区或目标TRP关联；2)第一TRP的相关信息指向目标小区或目标TRP；3)第一RS指向目标小区或目标TRP；4)第一TCI指向目标小区或目标TRP；5)第一空间相关信息指向目标小区或目标TRP；6)第一随机接入信道(Random Access Channel，RACH)资源指向目标小区或目标TRP。
可选地，在S102之前，终端设备还可以根据当前小区配置进行无线资源管理(Radio Resource Management，RRM)测量，无线链路管理(Radio Link Management，RLM)测量或波束测量等，终端设备完成相关的测量后，即可进行RRM上报，RLM上报或波束上报。
根据终端设备上报的测量内容，网络设备可以为终端设备进行上述至少之一的配置/更新/激活，指示终端设备进行小区切换。这样，终端设备在发现满足上述至少之一的情况下，即可由源小区切换至目标小区或目标TRP。也即在满足上述至少之一的情况下，终端设备进行小区切换，具体地，终端设备可以将RRC连接至目标小区或目标TRP，并回复切换完成。
可以看出，上述条件的至少之一的配置均是和目标小区或目标TRP相关的，这样，终端设备在进行小区切换时，还可以直接利用上述配置，降低了小区切换的时延。
本申请实施例提供了多种方式隐式地指示终端设备进行小区切换，无需网络设备显式地发送RRC重配信令，提升了系统的灵活性，降低了小区切换的时延。
