具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚描述，显然，所描述的实施例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所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的术语在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”所区别的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”一般表示前后关联对象是一种“或”的关系。
值得指出的是，本申请实施例所描述的技术不限于长期演进型(Long Term Evolution，LTE)/LTE的演进(LTE-Advanced，LTE-A)系统，还可用于其他无线通信系统，诸如码分多址(Code Division Multiple Access，CDMA)、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 Frequency Division Multiple Access，SC-FDMA)和其他系统。本申请实施例中的术语“系统”和“网络”常被可互换地使用，所描述的技术既可用于以上提及的系统和无线电技术，也可用于其他系统和无线电技术。以下描述出于示例目的描述了新空口(New Radio，NR)系统，并且在以下大部分描述中使用NR术语，但是这些技术也可应用于NR系统应用以外的应用，如第6代(6th Generation，6G)通信系统。
图1示出本申请实施例可应用的一种无线通信系统的框图。无线通信系统包括终端11和网络侧设备12。其中，终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant，PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer，UMPC)、移动上网装置(Mobile Internet Device，MID)、增强现实(augmented reality，AR)/虚拟现实(virtual  reality，VR)设备、机器人、可穿戴式设备(Wearable Device)、车载设备(Vehicle User Equipment，VUE)、行人终端(Pedestrian User Equipment，PUE)、智能家居(具有无线通信功能的家居设备，如冰箱、电视、洗衣机或者家具等)、游戏机、个人计算机(personal computer，PC)、柜员机或者自助机等终端侧设备，可穿戴式设备包括：智能手表、智能手环、智能耳机、智能眼镜、智能首饰(智能手镯、智能手链、智能戒指、智能项链、智能脚镯、智能脚链等)、智能腕带、智能服装等。需要说明的是，在本申请实施例并不限定终端11的具体类型。网络侧设备12可以包括接入网设备或核心网设备，其中，接入网设备也可以称为无线接入网设备、无线接入网(Radio Access Network,RAN)、无线接入网功能或无线接入网单元。接入网设备可以包括基站、无线局域网(Wireless Local Area Network，WLAN)接入点或WiFi节点等，基站可被称为节点B、演进节点B(eNB)、接入点、基收发机站(Base Transceiver Station，BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、家用B节点、家用演进型B节点、发送接收点(Transmitting Receiving Point，TRP)或所述领域中其他某个合适的术语，只要达到相同的技术效果，所述基站不限于特定技术词汇，需要说明的是，在本申请实施例中仅以NR系统中的基站为例进行介绍，并不限定基站的具体类型。
双连接(Dual Connectivity，DC)，即为终端(User Equipment，UE)提供两个网络节点(接入网网元)的资源，其中一个网络节点称为主节点(Master node，MN)，另一个称为辅节点(Secondary node，SN)。在每个网络节点，使用了载波聚合技术(CA)，即为UE配置由该节点控制的一系列服务小区，也称小区组(cell group)。主节点MN控制的为主小区组(Master Cell Group，MCG)，辅节点SN控制的为辅小区组(Secondary Cell Group，SCG)。每个小区组都包含一个特殊小区(Special Cell，SpCell)和一系列辅小区(Secondary Cell，Scell)。在MCG中特殊小区称为主小区(Primary Cell，PCell)，在SCG中特殊小区称为主辅小区(Primary Secondary Cell，PSCell)。在一个小区组中SpCell使用主载波，而其他辅小区使用辅载波，一个小区组内的资源调度由SpCell进行。
条件主辅小区组添加或变更过程(Conditional PSCell Addition or Change，CPAC)包括：
1)条件主辅小区添加(Conditional PSCell Addition,CPA)
条件主辅小区添加是UE评估执行条件并在执行条件满足后执行的主辅小区添加。
CPA配置包含CPA候选小区的配置和执行条件。执行条件可能包含一个到两个触发条件。
条件主辅小区变更(Conditional PSCell Change,CPC)
条件主辅小区变更是UE评估执行条件并在执行条件满足后执行的主辅小区变更。UE接收到CPC配置后开始评估执行条件。UE在主辅小区变更触发后停止评估执行条件。
CPC配置包含CPC候选小区的配置和执行条件。执行条件可能包含一个到两个触发条件。一旦成功完成主辅小区变更过程，UE释放所有存储的CPC配置。
CPC包括多种场景,如：
-辅节点内主辅小区条件变更(Intra-SN CPC)；
-主节点发起的辅节点间主辅小区条件变更(MN initiated Inter-SN CPC)；
-辅节点发起的辅节点间主辅小区条件变更(SN initiated Inter-SN CPC)。
辅节点发起的辅节点间主辅小区条件变更包括以下流程：
步骤1、源辅节点(Source-SN,S-SN)发起CPAC；
步骤2、主节点MN向至少一个目标辅节点(Target-SN,T-SN)发送辅节点添加请求；
步骤3、T-SN向MN发送辅节点添加确认信息，包括一个或多个候选小区配置；
步骤4、可选地，MN向S-SN发送候选PSCell的接受信息；
步骤5、可选地，S-SN更新CPAC配置信息；
步骤6、MN发送Early data forwarding信息；
步骤7、MN给UE发送无线资源控制(Radio Resource Control，RRC)重配置消息，包含CPAC命令；
步骤8、UE发送重配置完成消息，确认接收到RRC重配置消息；
步骤9、UE触发CPAC执行条件,发送RRC重配置完成消息；
步骤10、MN向S-SN发送SN变更确认消息；
步骤11、MN向T-SN发送辅节点重配置完成消息；
步骤12、UE随机接入到T-SN。
后续步骤略。
现有的CPAC流程中，当完成一次CPAC执行后，所配置的CPAC条件配置就会被释放，不会保留候选小区。因此，如果网络侧没有重配置CPAC,终端就没有机会基于之前配置的CPAC候选小区继续执行CPAC。
下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的候选小区处理方法进行详细地说明。
本申请实施例提供一种候选小区处理方法，如图2所示，包括：
步骤101：终端接收网络侧设备配置的M个候选小区配置信息，M为正整数；
在小区组变更后，所述终端执行以下至少一项：
删除N个候选小区配置信息，其中，N为小于M的正整数；
保留P个候选小区配置信息，其中，P为小于或等于M的正整数；
在第一指示信息指示删除所有候选小区配置信息的情况下，删除所述M个候选小区配置信息；
在第二指示信息指示删除的候选小区配置信息为所有候选小区配置信息的情况下，删除所述M个候选小区配置信息；
在第三指示信息指示没有要保留的候选小区配置信息的情况下，删除所述M个候选小区配置信息；
其中，所述第一指示信息用于指示是否删除所有候选小区配置信息；
所述第二指示信息用于指示删除的候选小区配置信息；
所述第三指示信息用于指示保留的候选小区配置信息；
所述小区组变更包括主小区组MCG和/或辅小区组SCG变更。
在本申请实施例中，小区组变更后，可以不删除所有候选小区配置信息，可以保留部分候选小区配置信息，这样在小区组变更后，无需网络侧设备进 行重配置，终端可以基于之前配置的候选小区配置信息继续执行条件切换(CHO)、或条件主辅小区添加(CPA)、或条件主辅小区变更(CPC)过程。
其中，所述候选小区配置信息包括候选小区(比如候选小区的标识(Identity Document，ID))和/或候选小区关联的配置信息，所述候选小区关联的配置信息可以包括以下至少一项：条件重配置(例如ConditionalReconfiguration，该信息元素用于添加、修改或释放条件重配置的配置)和执行条件重配置的触发条件。
本实施例中，在小区组变更后，可以对单个候选小区进行删除或保留，也可以对所有候选小区进行删除或保留，或者，对MN/SN配置的候选小区进行删除或保留，能够灵活删除或保留候选小区。
一些实施例中，在网络侧设备仅配置第一指示信息的情况下，所述删除N个候选小区配置信息包括：在所述第一指示信息指示不删除所有候选小区配置信息的情况下，删除N个候选小区配置信息；或，
所述保留P个候选小区配置信息包括：在所述第一指示信息指示不删除所有候选小区配置信息的情况下，保留P个候选小区配置信息。
其中，所述第一指示信息可以指示支持连续的CPA和/或CPC，如第一指示信息为subsequentCPAC，如果配置了subsequentCPAC或subsequentCPAC值为TRUE，表示支持连续的CPAC过程，即不删除所有候选小区配置信息。
一些实施例中，所述第一指示信息包含在无线资源控制RRC重配置消息中。第一指示信息并不局限于包含在无线资源控制RRC重配置消息中，还可以通过新定义的消息携带。
一可选示例中，终端接收RRC重配置消息，所述RRC重配置消息包含条件重配置和第一指示信息，条件重配置包含列表CondReconfigToAddMod，其中，所述列表可以包含以下至少一项：条件重配置标识、多个候选小区对应的配置信息、触发执行条件重配置需要满足的触发条件。其中，多个候选小区对应的配置信息可以是候选小区的配置信息。
一些实施例中，所述第一指示信息包含在以下至少一项信息元素中：
MCG对应的条件重配置信息元素conditionalReconfiguration；
SCG对应的条件重配置信息元素mrdc-SecondaryCellGroup。
一些实施例中，所述第一指示信息显式指示是否删除所有候选小区配置信息，比如，第一指示信息的值为TRUE，则删除所有候选小区配置信息；第一指示信息的值不为TRUE，则不删除所有候选小区配置信息；或者，第一指示信息的值不为TRUE，则删除所有候选小区配置信息；第一指示信息的值为TRUE，则不删除所有候选小区配置信息。
或者，通过是否配置有第一指示信息指示是否删除所有候选小区配置信息。比如，若配置有第一指示信息，则所述第一指示信息指示删除所有候选小区；若未配置有第一指示信息，则指示不删除所有候选小区。或者，若未配置有第一指示信息，则指示删除所有候选小区；若配置有第一指示信息，则第一指示信息指示不删除所有候选小区。
一具体示例中，当SCG成功完成随机接入过程后，如果配置了CPA或CPC，且第一指示信息没有被配置时，终端删除包含在条件重配置变量(VarConditionalReconfig)内的候选所有项(即全部CPA或CPC的候选小区)；如果SCG的spCellConfig中包含了reconfigurationWithSync，并且配置了CPA或CPC，但未配置后续CPAC(subsequent CPAC)，删除VarConditionalReconfig中的所有项(Entry)。
另一具体示例中，当小区组变更后，终端删除包含在条件重配置变量(VarConditionalReconfig)内的所有未配置第一指示信息的项。
一些实施例中，在网络侧设备仅配置第二指示信息和/或第三指示信息的情况下，所述删除N个候选小区配置信息包括：
根据第二指示信息或第三指示信息确定删除N个候选小区配置信息，所述第二指示信息用于指示删除的候选小区配置信息，所述第三指示信息用于指示保留的候选小区配置信息。
通过第二指示信息可以灵活指示需要删除的候选小区配置信息，删除N个候选小区配置信息包括：删除第二指示信息指示删除的候选小区及其关联的配置信息；通过第三指示信息可以灵活指示需要保留的候选小区配置信息，保留P个候选小区配置信息包括：保留第三指示信息指示保留的候选小区及其关联的配置信息。
一些实施例中，第三指示信息可以为CandidateKept，如果候选小区配置 信息配置了CandidateKept或CandidateKept值为TRUE,表示需要对应的候选小区配置信息。
一些实施例中，所述保留P个候选小区配置信息包括：
