Description

一种信息上报方法及装置 技术领域
本申请涉及通信技术领域，特别涉及一种信息上报方法及装置。
背景技术
第五代移动通信技术(the 5th Generation mobile communicationtechnology，5G)应用日益广泛。为了充分利用5G的带宽资源，可以采用时分双工(Tim-division duplex，TDD)模式。TDD模式是一种上下行采用相同的频带，在一个频带内上下行链路使用不同时隙的通信模式。终端设备当前驻留的服务小区与邻小区的频段相同时，该邻小区与服务小区为同频小区，其中，该邻小区为服务小区的同频邻区。在TDD网络部署中，当同频小区之间保持子帧边界同步，且同频小区内配置的上下行配比相同时，同频小区之间保持同步。在TDD模式下，同频小区之间未保持同步时，终端设备无法向接入网设备上报同频邻区的测量结果，并且，信号质量强的同频邻区可能对服务小区的信号干扰，导致终端设备长时间驻留在信号质量较差的小区，无法切换到信号质量好的同频邻区。
发明内容
本申请实施例提供了一种信息上报方法及通信装置，可以在TDD模式下，同频小区之间未保持同步时，及时上报同频邻区的测量结果。
第一方面，本申请提供一种信息上报方法，该方法包括：终端设备对终端设备的第一同频邻区发送的第一同步信号块SSB中的物理广播信道PBCH进行解码，得到第一SSB的索引，第一同频邻区采用时分双工模式进行通信，第一同频邻区与终端设备的服务小区异步；终端设备对第一SSB进行测量，得到第一SSB的信号测量结果；终端设备向接入网设备上报第一SSB的信号测量结果与第一SSB的索引。终端设备在TDD模式下，对异步小区发送的SSB中的PBCH解码，得到异步小区的SSB的索引，可以在TDD模式下，同频小区之间未保持同步时，及时上报异步小区的测量结果。
在一种可能的实现中，终端设备对终端设备的第一同频邻区发送的第一同步信号块SSB中的物理广播信道PBCH进行解码，得到第一SSB的索引之前，方法还包括：终端设备确定第一同频邻区与终端设备的服务小区异步。终端设备判断第一同频邻区是否为异步小区，以使对异步小区发送的SSB中的PBCH解码，得到异步小区的SSB的索引，可以在TDD模式下，及时上报异步小区的测量结果，减少负载。
在一种可能的实现中，终端设备对终端设备的第一同频邻区发送的第一同步信号块SSB中的物理广播信道PBCH进行解码，得到第一SSB的索引之后，还包括：终端设备对终端设备的第二同频邻区发送的第二同步信号块SSB中的物理广播信道PBCH进行解码，得到第二SSB的索引，第二同频邻区与终端设备的服务小区同步；终端设备对第二SSB进行测量，得到第二SSB的信号测量结果；终端设备向接入网设备上报第二SSB的信号测量结果与第二SSB的索引。终端设备对第一同频邻区之后测量的同步小区发送的SSB中的PBCH解码，得到第二SSB的索引。也即是说，终端设备不用判断第二同频邻区是否为同步小区或异步小区，对第一个异步小区及其之后测量的所有同频小区，无论是同步小 区还是异步小区，全部按照异步小区的处理方式，均采用对SSB中的PBCH解码，得到小区的SSB的索引，有利于简化流程，可行性高，控制流程简单。
在一种可能的实现中，终端设备对终端设备的第一同频邻区发送的第一同步信号块SSB中的物理广播信道PBCH进行解码，得到第一SSB的索引之后，还包括：终端设备确定终端设备的第二同频邻区是否与终端设备的服务小区同步；若第二同频邻区与终端设备的服务小区同步，则基于终端设备存储的频点和SSB索引之间的对应关系，以及第二同频邻区发送的第二SSB所在的频点，确定第二SSB的索引；终端设备对第二SSB进行测量，得到第二SSB的信号测量结果；终端设备向接入网设备上报第二SSB的信号测量结果与第二SSB的索引。终端设备基于存储的频点和SSB索引之间的对应关系确定同步小区的SSB的索引，能够避免对新出现的同步小区发送的SSB中的PBCH进行解码造成的上报时延，可以降低负载，有利于及时上报同频邻区的测量结果，及时切换到信号质量好的同频邻区。
在一种可能的实现中，终端设备确定第一同频邻区与终端设备的服务小区异步，包括：终端设备基于存储的频点和SSB索引之间的对应关系和第一SSB的频点，确定第一同频邻区与终端设备的服务小区异步。终端设备基于存储的频点和SSB索引之间的对应关系确定第一同频邻区是否为异步小区，有利于避免对同步小区发送的SSB中的PBCH进行解码，能够提高效率，减少上报时延，同时对异步小区发送的SSB中的PBCH解码，得到异步小区的SSB的索引，可以及时上报异步小区的测量结果。
在一种可能的实现中，信息上报方法还包括：终端设备对终端设备的第二同频邻区发送的第二同步信号块SSB中的物理广播信道PBCH进行解码，得到第二SSB的索引，第二同频邻区与终端设备的服务小区同步；终端设备对第二SSB进行测量，得到第二SSB的信号测量结果；终端设备向接入网设备上报第二SSB的信号测量结果与第二SSB的索引。也即是说，终端设备对所有的同步小区和异步小区均采用对SSB的PBCH解码，得到SSB的索引，终端设备无需判断第一同频邻区与第二同频邻区是否为同步小区或异步小区，可以减少流程，提高上报效率。

具体实施方式
本申请的说明书、权利要求书及附图中的术语“第一”和“第二”等是用于区别不同对象，而不是用于描述特定顺序。此外，术语“包括”和“具有”以及它们任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、系统、产品或设备没有限定于已列出的步骤或单元，而是可选地还包括没有列出的步骤或单元，或可选地还包括对于这些过程、方法、产品或设备固有的其它步骤或单元。
在本文中提及“实施例”意味着，结合实施例描述的特定特征、结构或特性可以包含在本申请的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是，本文所描述的实施例可以与其它实施例相结合。
在本申请中，“至少一个(项)”是指一个或者多个，“多个”是指两个或两个以上，“至少两个(项)”是指两个或三个及三个以上，“和/或”，用于描述关联对象的关联关系，表示可以存在三种关系，例如，“A和/或B”可以表示：只存在A，只存在B以及同时存在A和B三种情况，其中A，B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项(个)”或其类似表达，是指这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a，b或c中的至少一项(个)，可以表示：a，b，c，“a和b”，“a和c”，“b和c”，或“a和b和c”，其中a，b，c可以是单个，也可以是多个。
为了更好地理解本申请实施例，下面对本申请实施例涉及的专业术语进行介绍：
(一)同频邻区
终端设备当前驻留的服务小区与邻小区的频段相同时，该邻小区与服务小区为同频小区。
其中，该邻小区为服务小区的同频邻区。在TDD网络部署中，当同频小区之间保持子帧边界同步，且同频小区内配置的上下行配比相同时，同频小区之间保持同步，服务小区与邻小区同步，邻小区为服务小区的同频同步小区(简称同步小区)。当同频小区之间的子帧边界不同步，或同频小区内配置的上下行配比不相同时，服务小区与邻小区异步，邻小区为服务小区的同频异步小区(简称异步小区)。
(二)时分双工(Tim-division duplex，TDD)模式
TDD模式是一种收发共用一个射频频点，默认网络基本同步，即接收和传送是在同一个频率信道，在一个频带内上下行链路使用不同时隙的通信模式，即用时间来分离接收和传送信道。TDD网络部署需要小区之间保持子帧边界的精确同步(微秒级)，并在同一个TDD同步小区内配置成相同的上下行配比。
(三)同步信号块(Synchronization Signal Block，SSB)
在新空口(Newradio，NR)系统中，网络设备需要发送同步信号块(Synchronization Signal Block，SSB)以供终端设备进行同步、系统信息获取、测量等。SSB由主同步信号(PrimARy Synchronization Signals，PSS)、辅同步信号(Secondary Synchronization Signals，SSS)以及物理广播信道(Physical Broadcast Channel，PBCH)三部分共同组成。其中，PSS和SSS用于终端设备进行下行同步(包括定时同步、帧同步和符号同步)；PSS和SSS还用于获取小区标识码(Cell Identifier，CID)以及测量小区信号质量。
具体的，PSS用于获取小区标识码(Cell Identifier，CID)、确定小区通信模式为时分双工(Tim-division duplex，TDD)模式或者频分双工(Frequency division duplexing，FDD)模式，还可以用于时域同步，例如正交频分复用技术(Orthogonal frequency division multiplexing，OFDM)符号同步、时隙同步和/或频域同步等。SSS用于确定小区的物理层标识(Identity document，ID)，还可以用于测量小区的信号质量，以使终端设备与接入网设备根据测量结果选择波束和RRM测量等。SSB关联一个或多个用于承载随机接入消息的波束，用于接入网设备基于SSB关联的波束、通过SSB对应的小区与终端设备进行通信。其中，SSB通过唯一的SSB的索引对关联的波束进行标定。
当终端设备可以基于存储的频点和SSB索引之间的对应关系、和邻小区的SSB的频点，确定邻小区的SSB的索引时，说明服务小区与邻小区为同步小区，终端设备可以向接入网设备上报邻小区的SSB的索引与SSB的信号测量结果。当终端设备无法确定邻小区的SSB的索引，说明服务小区与邻小区为异步小区，终端设备无法向接入网设备上报异步小区的SSB的索引与SSB的信号测量结果，并且，信号质量强的同频邻区可能对服务小区的信号干扰，导致终端设备长时间驻留在信号质量较差的小区，无法切换到信号质量好的同频邻区。
其中，终端设备存储的频点和SSB索引之间的对应关系，为终端设备当前驻留的服务小区的频点和SSB索引之间的对应关系。终端设备当前驻留的服务小区的频点和SSB索引之间的对应关系，可以与终端设备历史驻留的服务小区的频点和SSB索引之间的对应关系不同。
如表1所示，终端设备存储服务小区174的频点与SSB的索引之间的对应关系为：服 务小区174包括8个频点范围及对应的SSB的索引，其中，处于[168，936]之间的频点对应SSB的索引为0，处于[1812，2580]之间的频点对应SSB的索引为1，处于[4008，4776]之间的频点对应SSB的索引为2，处于[5652，6420]之间的频点对应SSB的索引为3，处于[7848，8616]之间的频点对应SSB的索引为4，处于[9492，10260]之间的频点对应SSB的索引为5，处于[11688，12456]之间的频点对应SSB的索引为6，处于[13332，14100]之间的频点对应SSB的索引为7。
表1.服务小区174的频点与SSB的索引之间的对应关系
SSB的索引 频点
0 [168，936]
1 [1812，2580]
2 [4008，4776]
3 [5652，6420]
4 [7848，8616]
5 [9492，10260]
6 [11688，12456]
7 [13332，14100]
邻小区420的SSB的频点为170，终端设备基于上述表1所示的服务小区174的8个频点和SSB索引之间的对应关系、和邻小区420的SSB的频点，确定邻小区420的SSB的频点170处于[168，936]之间，对应的SSB的索引为0。终端设备确定邻小区420的SSB的索引为0。终端设备能够根据上述表1中的对应关系确定邻小区420的SSB的索引，说明邻小区420与服务小区174为同步小区。
邻小区419的SSB的频点为1000。终端设备基于上述表1所示的服务小区174的8个频点与SSB索引之间的对应关系，邻小区419的频点1000不处于表1中的8个频点范围内，终端设备无法根据表1中的对应关系确定邻小区419的SSB的索引，说明邻小区419与服务小区174为异步小区。
(四)同步信号块SSB的信号测量结果
SSB的信号测量结果表示SSB的信号质量，SSB的信号测量结果包括以下一个或多个参数：参考信号接收功率(Reference signal receiving power，RSRP)、接收信号强度指示(Received signal strength indicator，RSSI)、参考信号接收质量(Reference signal received quality，RSRQ)和信干噪比(Signal to interference noise ratio，SINR)。
其中，RSRP用于反映当前信道的路径损耗强度，用于小区覆盖的测量和小区选择/重选和切换；RSSI用于反映当前信道的接收信号强度和干扰程度；RSRQ用于反映和指示当前信道质量的信噪比和干扰水平；SINR用于反映当前信道的链路质量，是衡量终端设备性能参数的一个重要指标。
信号测量是移动性管理的基础，移动性管理是无线移动通信中的重要组成部分。移动性管理是为了保证接入网设备与终端设备之间的通信链路不因终端设备的移动而中断。根据终端设备的状态可以分为空闲态移动性管理和连接态移动性管理两部分。在空闲态下，移动性管理主要指的是小区选择/重选(Cell selection/reselection)的过程，在连接态下，移动性管理主要指的是小区切换(handover)。不论是小区选择/重选还是切换，都是基于信号测量的结果进行的。
(五)物理广播信道(Physical Broadcast Channel，PBCH)
PBCH用于无线帧号同步以及SIB1的配置。PBCH承载了用于解调PBCH所需的解调参考信号(DMRS)和用于获取小区参数信息的主信息块(Master information block，MIB)。其中，通过解析DMRS可以获得SSB的索引(SSB index)。终端设备通过SSB的索引向接入网设备上报SSB的信号测量结果，接入网设备基于SSB的索引确定SSB关联的用于接收数据的波束。
MIB包括对SIB1进行解析所需的必要参数配置信息，例如，MIB中包括关于应用于SIB1子载波间距的信息、SIB1的调度信息。SIB1包括用于终端设备在空闲态和连接态下所使用的定时器和常数信息。通过解析PBCH中的MIB，得到SIB1的调度信息，基于SIB1的调度信息接收小区的SIB1，可以得到小区的参数信息。小区的参数信息包括但不限于是：小区的带宽、帧号、子帧号、频点频段等。终端设备基于解析MIB和SIB1得到的小区的参数信息，确定小区是否可以驻留。
本申请实施例提供的方法应用于无线通信系统中。本申请实施例提供的方法可以应用于各类通信系统中，例如，可以是物联网(internet of things，IoT)系统、窄带物联网(narrow band internet of things，NB-IoT)系统、长期演进(long term evolution，LTE)系统，也可以是第五代(5th-generation，5G)通信系统，还可以是LTE与5G混合架构、也可以是5G新无线(new radio，NR)系统，以及未来通信发展中出现的新的通信系统等。
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，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，都属于本发明保护的范围。
本发明的说明书和权利要求书及上述附图中的术语“包括”以及它们任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或模块的过程、方法、系统、产品或设备没有限定于已列出的步骤或模块，而是可选地还包括没有列出的步骤或模块，或可选地还包括对于这些过程、方法、产品或设备固有的其它步骤或模块。

本申请实施例提供了一种信息上报方法及其装置，可以在TDD模式下，同频小区之间未保持同步时，及时上报同频邻区的测量结果。下面对本申请实施例提供的信息上报方法进一步进行详细描述：
请参见图2，图2是本申请实施例提供的一种信息上报方法的流程示意图。如图2所示，该信息上报方法包括如下S201～S203。图2所示的方法执行主体为终端设备，或主体可以为终端设备中的芯片。其中：
S201、终端设备对终端设备的第一同频邻区发送的第一同步信号块SSB中的物理广播信道PBCH进行解码，得到第一SSB的索引，第一同频邻区采用时分双工模式进行通信；第一同频邻区与终端设备的服务小区异步。
本申请实施例中，第一同频邻区为终端设备当前驻留的服务小区相邻的同频邻区。PBCH承载了用于解调PBCH所需的解调参考信号(DMRS)、用于获取小区参数信息的主信息块MIB和SIB1。终端设备可对第一SSB中的PBCH承载的DMRS解码，得到第一SSB的索引。可选的，终端设备可对第一PBCH承载的MIB与SIB1解析，得到第一同频邻区的参数信息。终端设备基于第一同频邻区的参数信息，确定第一同频邻区是否可以驻留。
本申请实施例中，每个同频邻区包括一个或多个同步信号块SSB。每个同步信号块SSB由一个PSS、一个SSS和一个PBCH组成，终端设备对PBCH承载的DMRS解码，得到SSB的索引。每个SSB的索引关联一个用于同频邻区通信的波束的标识(beam ID)。第一同频邻区发送的第一同步信号块SSB为多个时，终端设备对每个第一同步信号块SSB中的PBCH承载的DMRS分别解码，得到多个第一SSB的索引。每个第一SSB的索引分别关联不同的波束标识。
例如，第一同频邻区发送的第一同步信号块SSB为两个，分别为SSB1和SSB2，参见图3所示的SSB结构示意图，SSB1由PSS1、SSS1和PBCH1组成，SSB2由PSS2、SSS2和PBCH2组成。终端设备对PBCH1承载的DMRS1解码，得到SSB1的索引，终端设备对PBCH2承载的DMRS2解码，得到SSB2的索引。SSB1的索引关联波束1的标识，SSB2的索引关联波束2的标识。
终端设备对SSB1和SSB2中的PBCH承载的主信息块MIB解析，得到SIB1的调度信息，基于SIB1的调度信息接收第一同频邻区419的SIB1，对第一同频邻区419的SIB1解析，得到第一同频邻区419的参数信息(包括小区的带宽、帧号、子帧号、频点频段等参数信息)。
S202、终端设备对第一SSB进行测量，得到第一SSB的信号测量结果。
需要说明的是，步骤S202与步骤S201的执行顺序不分先后。步骤S202可以与步骤S201同时执行，步骤S202也可以在步骤S201之前执行，步骤S202还可以在步骤S201之后执行，本申请实施例不做限定。
在一种实现方式中，终端设备对第一SSB进行测量，得到第一SSB的信号测量结果，第一SSB的信号测量结果包括以下一个或多个参数：参考信号接收功率RSRP、接收信号强度指示RSSI、参考信号接收质量RSRQ和信干噪比SINR。第一SSB的信号测量结果还可以包括其他的参数，本申请实施例不做限定。
S203、终端设备向接入网设备上报第一SSB的信号测量结果与第一SSB的索引。
相应地，接入网设备可以接收第一SSB的信号测量结果与第一SSB的索引。接入网设备接收到第一SSB的索引以及信号测量结果之后，若第一SSB的信号测量结果(代表第一同频邻区的信号质量)满足预设切换条件，则从服务小区切换至第一同频邻区。接入网设备基于该第一SSB的索引关联的波束标识，确定传输数据的波束。其中，预设切换条件可以是第一同频邻区的信号质量好于服务小区的信号质量。
例如，终端设备向接入网设备上报第一同频邻区419的SSB1的索引以及SSB1的信号测量结果，若SSB1的信号测量结果满足预设切换条件，接入网设备从服务小区切换至第一同频邻区。并基于SSB1的索引关联的波束1的标识，确定用于传输数据的波束为波束1。
在一种实现方式中，终端设备获取用于筛选第一同频邻区的上报条件，上报条件可以是第一SSB的信号测量结果表示的信号质量满足预设值。终端设备基于解析第一同频邻区的MIB和SIB1得到的第一同频邻区的参数信息，并确定第一同频邻区的参数消息是否满足上报条件。若满足上报条件，说明第一同频邻区可以驻留，则终端设备向接入网设备上报第一同频邻区的第一SSB的索引以及信号测量结果。其中，接入网设备可以是服务小区对应的接入网设备，也可以是第一同频邻区对应的接入网设备。
具体的，当第一同频邻区的第一同步信号块SSB为一个，且对第一PBCH解码得到的唯一的第一SSB满足上报条件时，终端设备向接入网设备上报该第一SSB的索引以及信号测量结果。当第一同频邻区的第一同步信号块SSB为多个，对第一SSB中的PBCH解码得到多个第一SSB时，终端设备向接入网设备上报满足上报条件的第一SSB的索引以及信号测量结果。
在一种实现方式中，终端设备向接入网设备上报的第一SSB的索引以及信号测量结果为多个时，接入网设备基于多个第一SSB的信号质量，在多个第一SSB中确定目标第一 SSB。接入网设备根据目标第一SSB的索引关联的波束标识，确定传输数据的波束。
例如，终端设备向接入网设备上报第一同频邻区的SSB1的索引、SSB1的信号测量结果、SSB2的索引以及SSB2的信号测量结果，接入网设备从服务小区切换至第一同频邻区。其中，SSB1的信号质量比SSB2的信号质量好，接入网设备确定SSB1为目标第一SSB。接入网设备根据SSB1的索引关联的波束1的标识，确定用于传输数据的波束为波束1。
通过图2所描述的信息上报方法，终端设备对终端设备的第一同频邻区(可以是同步小区或异步小区)发送的第一同步信号块SSB中的物理广播信道PBCH进行解码，得到第一SSB的索引，第一同频邻区采用时分双工模式进行通信，第一同频邻区与服务小区异步；终端设备对第一SSB进行测量，得到第一SSB的信号测量结果；终端设备向接入网设备上报第一SSB的信号测量结果与第一SSB的索引。终端设备在TDD模式下，对异步小区发送的SSB中的PBCH解码，得到异步小区的SSB的索引，能够及时上报异步小区的测量结果，从而切换到信号质量好的同频邻区。
参见图4，图4是本申请提供是本申请实施例提供的另一种信息上报方法的流程示意图。如图4所示，该信息上报方法如下步骤S401至步骤S407：
S401，终端设备确定第一同频邻区与终端设备的服务小区异步。
本申请实施例中，终端设备可以基于存储的频点和SSB的索引之间的对应关系，以及第一SSB的频点，确定第一同频邻区与终端设备的服务小区异步。具体的，终端设备获取第一同频邻区的第一SSB，并基于第一SSB中的第一PSS和第一SSS确定第一SSB的频点。若第一SSB的频点处于服务小区的第n个频点范围内，确定第一同频邻区与终端设备的服务小区同步，且确定服务小区的第n个频点范围对应的SSB索引为第一SSB的索引。若第一SSB的频点不处于服务小区的n个频点范围内，确定第一同频邻区与终端设备的服务小区异步。
例如，终端设备获取第一同频邻区419的第一SSB，并基于第一SSB中的第一PSS和第一SSS确定第一SSB的频点为1000。终端设备基于上述表1所示的服务小区174的8个频点与SSB索引之间的对应关系，第一SSB的频点不处于SSB的索引0～7对应的频点范围内，确定第一同频邻区419与服务小区174异步。
S402，终端设备对终端设备的第一同频邻区发送的第一同步信号块SSB中的物理广播信道PBCH进行解码，得到第一SSB的索引，第一同频邻区采用时分双工模式进行通信，第一同频邻区与服务小区异步。
需要说明的是，步骤S402的执行过程可以参见图2中的步骤S201中终端设备对第一同步信号块SSB中的物理广播信道PBCH进行解码的具体描述，此处不再赘述。
S403，终端设备对第一SSB进行测量，得到第一SSB的信号测量结果。

S405，终端设备对终端设备的第二同频邻区发送的第二同步信号块SSB中的物理广播信道PBCH进行解码，得到第二SSB的索引，第二同频邻区与终端设备的服务小区同步。
在一种实现方式中，第二同频邻区为第一同频邻区之后测量的同步邻区。终端设备对终端设备的第二同频邻区发送的第二同步信号块SSB(第二同步信号块SSB可以为一个或多个)中的物理广播信道PBCH进行解码，得到第二SSB的索引。具体的，终端设备对第二PBCH承载的DMRS解码，得到第一SSB的索引，对第一PBCH承载的MIB与SIB1解析，得到第一同频邻区的参数信息。终端设备基于第二同频邻区的参数信息，确定第二同频邻区是否可以驻留。也即是说，终端设备测量到第一个异步小区及其之后的所有同步小区，均采用对SSB的PBCH解码的方法，得到第一个异步小区及其之后的所有同步小区的SSB的索引。
在一种实现方式中，第二同频邻区发送的第二同步信号块SSB为多个时，终端设备对每个第二同步信号块SSB中的PBCH承载的DMRS分别解码，得到多个第二SSB的索引和第二同频邻区的参数信息。每个第二SSB的索引分别关联不同的波束标识。例如，第二同频邻区发送的第二同步信号块SSB为两个，分别为SSB3和SSB4时，终端设备分别对SSB3和SSB4中的PBCH解码，得到SSB3的索引、SSB4的索引以及第二同频邻区的参数信息。
S406，终端设备对第二SSB进行测量，得到第二SSB的信号测量结果。

S407，终端设备向接入网设备上报第二SSB的信号测量结果与第二SSB的索引。
在一种实现方式中，终端设备获取用于筛选上报的第二同频邻区的上报条件。终端设备基于解析第二同频邻区的MIB和SIB1得到的第二同频邻区的参数信息，并确定第二同频邻区的参数消息是否满足上报条件。若满足上报条件，说明第二同频邻区可以驻留，则终端设备向接入网设备上报第二同频邻区的第二SSB的索引以及信号测量结果。
具体的，当第二同频邻区的第二同步信号块SSB为一个，且对第二PBCH解码得到的唯一的第二SSB满足上报条件时，终端设备向接入网设备上报该第二SSB的索引以及信号测量结果。当第二同频邻区的第二同步信号块SSB为多个，对第二SSB中的PBCH解码得到多个第二SSB时，终端设备向接入网设备上报满足上报条件的第二SSB的索引以及信号测量结果。
相应地，接入网设备接收到终端设备上报的第一SSB的索引以及信号测量结果、第二SSB的索引以及信号测量结果之后，接入网设备从服务小区切换至满足切换条件的SSB对应的邻小区。切换条件可以是：第一SSB的信号测量结果、第二SSB的信号测量结果以及服务小区的SSB的信号测量结果中，信号质量最优的SSB。
若第一SSB的信号测量结果(代表第一同频邻区的信号质量)最优，则从服务小区切换至第一同频邻区，并基于第一同频邻区的第一SSB的索引关联的波束标识，确定传输数据的波束。当第一SSB的索引为多个时，接入网可以选择信号质量最好的第一SSB对应的波束。
若第二SSB的信号测量结果(代表第二同频邻区的信号质量)最优，则从服务小区切换至第二同频邻区。并基于第二同频邻区的第二SSB的索引关联的波束标识，确定传输数据的波束。当第二SSB的索引为多个时，接入网可以选择信号质量最好的第二SSB对应的波束。
若服务小区的SSB的信号测量结果最优，则继续驻留在当前服务小区。
例如，终端设备向接入网设备上报第一同频邻区的SSB1的索引、SSB1的信号测量结果、SSB2的索引以及SSB2的信号测量结果，第二同频邻区的SSB3的索引、SSB3的信号测量结果、SSB4的索引以及SSB4的信号测量结果。其中，根据各个SSB的信号测量结果，确定信号质量从强到弱分别为：SSB1>SSB2>SSB3>SSB4>服务小区的SSB。接入网设备切换至第一同频邻区，并基于SSB1的索引关联的波束标识，确定用于传输数据的波束。
第一同频邻区为终端设备测量到的异步小区，第二同频邻区为第一同频邻区之后测量的同步小区，终端设备对第一同频邻区发送的SSB中的PBCH解码，得到第一SSB的索引；终端设备对第一同频邻区之后测量的同步小区发送的SSB中的PBCH解码，得到第二SSB的索引。也即是说，终端设备对测量到的第一个异步小区的SSB中的PBCH解码，得到第一SSB的索引；在异步小区之后测量到的同步小区，终端设备对其发送的SSB中的PBCH解码，得到第二SSB的索引；在异步小区之后测量到的异步小区，终端设备也对其发送的SSB中的PBCH解码，得到SSB的索引。终端设备对第一个异步小区之后测量的同频小区，不用判断是否为同步小区或异步小区，全部按照异步小区的处理方式，均采用对SSB中的PBCH解码，得到小区的SSB的索引，简化流程，可行性高，控制流程简单。
通过图4所描述的信息上报方法，终端设备确定第一同频邻区与终端设备的服务小区异步，对第一同频邻区发送的第一同步信号块SSB中的物理广播信道PBCH进行解码，得到第一SSB的索引，向接入网设备上报第一SSB的信号测量结果与第一SSB的索引。终端设备对第二同频邻区发送的第二同步信号块SSB中PBCH进行解码，得到第二SSB的索引，第二同频邻区与服务小区同步；终端设备向接入网设备上报第二SSB的信号测量结果与第二SSB的索引。也即是说，终端设备不用判断第二同频邻区是否为同步小区或异步小区，对第一个异步小区及其之后测量的所有同频小区，无论是同步小区还是异步小区，全部按照异步小区的处理方式，均采用对SSB中的PBCH解码，得到小区的SSB的索引。简化流程，可行性高，控制流程简单。

S502，终端设备对终端设备的第一同频邻区发送的第一同步信号块SSB中的物理广播信道PBCH进行解码，得到第一SSB的索引，第一同频邻区采用时分双工模式进行通信，第一同频邻区与服务小区异步。

S505，终端设备确定终端设备的第二同频邻区是否与终端设备的服务小区同步；若第二同频邻区与终端设备的服务小区同步，则基于终端设备存储的频点和SSB索引之间的对应关系，以及第二同频邻区发送的第二SSB所在的频点，确定第二SSB的索引。
在一种实现方式中，终端设备基于第二同频邻区的第二SSB的PSS与SSS，确定第二SSB的频点。终端设备可以基于存储的服务小区的频点和SSB的索引之间的对应关系，以及第二SSB的频点，确定第二SSB的频点是否处于存储的服务小区的频点范围内。若第二SSB的频点处于存储的服务小区的频点范围内，则确定第二同频邻区与终端设备的服务小区同步，第二同频邻区为同步小区。基于终端设备存储的频点和SSB索引之间的对应关系，确定对应关系中第二SSB所在的频点对应的SSB的索引为第二SSB的索引。
例如，第二同频邻区420的SSB的频点为170，终端设备基于上述表1所示的服务小区174的8个频点和SSB索引之间的对应关系、和第二同频邻区420的SSB的频点，确定第二同频邻区420的SSB的频点170处于[168，936]之间，对应的SSB的索引为0。终端设备确定第二同频邻区420的SSB的索引为0。

通过图5所描述的信息上报方法，终端设备对第一同频邻区发送的SSB中的PBCH进行解码，得到第一SSB的索引，向接入网设备上报第一SSB的信号测量结果与第一SSB的索引；终端设备基于终端设备存储的频点和SSB索引之间的对应关系，以及同步小区发送的SSB，确定第二SSB的索引，第二同频邻区与服务小区同步；终端设备向接入网设备上报第二SSB的信号测量结果与第二SSB的索引。终端设备对异步小区发送的SSB中的PBCH解码，得到异步小区的SSB的索引，基于终端设备存储的频点和SSB索引之间的对应关系，以及同步小区发送的SSB所在的频点确定同步小区的SSB的索引。能够避免对新出现的同步小区发送的SSB中的PBCH进行解码造成的上报时延，可以降低负载。可以 在TDD模式下，同频小区之间未保持同步时，终端设备及时上报同频邻区的测量结果，及时切换到信号质量好的同频邻区。
