Description

小区选择或重选方法、装置和系统 技术领域
本申请涉及通信领域。
背景技术
实现工业物联网是第五代移动通信技术(5G)的重要目标之一，在大规模工业无线传感器网络(IWSN)应用场景中，除了需要应用一些像高可靠低时延通信(URLLC，Ultra-Reliable and Low-Latency Communication)这种高端能力的终端设备外，更多的情况下只需要中低端能力的终端设备，包括温度湿度传感器、压力传感器、加速器、运动传感器等。另外，在另一个5G的垂直行业应用场景智慧城市中，广泛部署视频监控摄像机是一个重要的应用，监控摄像头也无需采用高端能力终端设备。此外，还有大量的可穿戴设备，例如智能手表、手环、可穿戴医学监测设备等，对终端设备的处理能力要求也较低。
以上这些需要广泛应用的设备性能比Rel-15/Rel-16终端设备更低，但是要高于低功率广区域(Low Power Wide Area，LPWA)设备(例如，NB-IoT和LTE-M)，这些设备基本特征有：相较于URLLC和增强的移动宽带(eMBB，enhanced Mobile Broadband)设备更低的复杂度、紧凑的结构和更小的设备尺寸、电池使用时间可持续到一年以上。但现有的Rel-15/16 5G系统并不能很好地支持这种能力较低的终端设备，因此，目前5G终端设备的成本普遍较高。
为了实现对中低端新无线(NR)设备的支持，降低5G终端设备的成本，第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)在Rel-17中开始了针对研究减少能力(Reduced Capability，RedCap)的终端设备(以下简称UE)的研究项目，该研究的目的是明确相对于Rel-16的eMBB和URLLC NR设备，能力降低NR设备的特征和能力参数，并提升能力降低NR设备的节电性能和电池寿命及使用时间。能力降低NR设备的低复杂度和更低的处理能力主要体现在这几个方面：降低的设备收发天线个数、更窄的传输带宽、只支持半双工FDD、数据处理时间更长和降低的调制解调能力。能力降低UE需要将能力上报网络，使得网络可以根据能力降低UE的能力，对这些UE应用适当的传输方式，或对这些UE应用更有效的节电机制。
在Rel17中，RedCap UE可支持的带宽远小于系统带宽和普通终端带宽。对于频率范围1(FR1)，RedCap UE可支持的最大带宽是20MHz，对于FR2，RedCap UE支持的最大带宽为100MHz。因为RedCap UE的带宽小于普通UE，为了给RedCap UE配置适合的部分带宽(bandwidth part，BWP)，引入了针对RedCap UE的初始BWP，其带宽小于RedCap UE支持的最大带宽。RedCap UE的初始BWP可以专门用于RedCap UE的控制信道、数据信道、各种参考信号和随机接入过程。
应该注意，上面对技术背景的介绍只是为了方便对本申请的技术方案进行清楚、完整的说明，并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本申请的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
发明内容
在现有方法中，针对普通UE的初始下行BWP必须包含小区定义的同步信号/物理广播信道块(Cell-defined SS/PBCH Block，CD-SSB)和控制资源集合0(control resource set 0，CORESET#0)。空闲状态的UE可以驻留在初始下行BWP上接收系统广播、监听寻呼以及进行初始随机接入和移动性测量，连接状态的UE可以基于CD-SSB的波束进行随机接入机会选择、无线资源管理(RRM)测量、无线链路测量(RLM)、波束失败检测和恢复。
如果针对RedCap UE的初始下行BWP也包含CD-SSB和CORSET#0，则RedCap UE和普通UE使用的资源将集中在同一频率范围，不利于系统负载均衡。为了充分利用所有频域资源以实现灵活的资源分配，用于RedCap UE的初始下行BWP可以不包含CD-SSB和CORSET#0。RedCap UE可以在专用于RedCap的初始下行BWP进行驻留并进行空闲/非激活状态下的寻呼监听。另外，处于对Rel18网络节能的考虑，一个进入节能状态的小区可能会停止发送CD-SSB和系统信息(包括调度系统信息的PDCCH)。
发明人发现，现有方法中，针对小区选择的过程，目前只支持针对CD-SSB的小区选择测量，即使RedCap UE搜索到小区的其他参考信号，必须将RF接收机调整到CD-SSB的频率进行小区选择的测量，将增加UE的功率开销。另外，如果一个进入节能状态的小区停止发送CD-SSB，终端设备也无法基于CD-SSB进行选择到该节能小区。
发明人发现，现有方法中，针对小区重选的过程，目前空闲或非激活状态UE是基于驻留小区的CD-SSB进行小区重选测量。图2是普通UE和RedCap UE初始下行BWP示意图，如果空闲/非激活状态的RedCap UE驻留在专用于RedCap的初始下行BWP上监听寻呼，而RedCap的初始下行BWP不包含CD-SSB，如图2所示，RedCap UE必须从RedCap UE的初始下行BWP跳回到普通UE的初始下行BWP上测量CD-SSB以进行移动性测量。这样会导致空闲/非激活状态状态RedCap UE频繁在不同中心频率之间切换射频RF接收机，使得RedCap UE需要被配置测量间隔(measurement gap)，非常不利于RedCap UE的频谱效率和节能。另外，如果一个进入节能状态的小区停止发送CD-SSB，终端设备也无法基于该小区的CD-SSB进行小区重选的移动性测量。
为了解决上述问题的至少一种或其它类似问题，本申请实施例提供了一种小区选择或重选方法、装置和系统。
根据本申请实施例的一方面，提供一种小区选择或重选装置，应用于终端设备中，该装置包括：
第一接收单元，其接收网络设备发送的用于使用服务小区的第一参考信号进行小区选择或重选的相关信息，和/或用于使用服务小区的第二参考信号进行小区选择或重选的相关信息；
处理单元，其使用该服务小区的第二参考信号进行小区选择或重选的测量。
根据本申请实施例的一方面，提供一种信息发送装置，应用于网络设备侧，其特征在于，该装置包括：
第一发送单元，其向终端设备发送用于使用服务小区的第一参考信号进行小区选择或重选的相关信息；和/或，
第二发送单元，其向终端设备发送用于使用服务小区的第二参考信号进行小区选择或重选的相关信息。
本申请实施例的有益效果之一在于：网络设备向终端设备发送使用第二参考信号进行小区选择或重选的相关信息，由此，终端设备可以使用该第二参考信号进行小区选择或重选，而无需使用CD-SSB进行小区选择或重选的测量，可以减少UE在不同频率之间的切换，提高传输效率和节能。另外，使得驻留在节能状态的小区(即不发送CD-SSB)的终端设备也可以进行小区重选的测量，或者，使得终端设备可以选择 到一个节能状态的小区。

以下结合各个实施例进行说明。
第一方面的实施例
本申请实施例提供一种小区选择或重选方法，从终端设备侧进行说明。
图3是本申请实施例的小区选择或重选方法的一示意图，如图3所示，该方法包括：
301，终端设备接收网络设备发送的用于使用服务小区的第一参考信号进行小区选择或重选的相关信息，和/或用于使用服务小区的第二参考信号进行小区选择或重选的相关信息；
302，该终端设备使用该服务小区的第二参考信号进行小区选择或重选的测量。
值得注意的是，以上附图3仅对本申请实施例进行了示意性说明，但本申请不限于此。例如可以适当地调整各个操作之间的执行顺序，此外还可以增加其它的一些操作或者减少其中的某些操作。本领域的技术人员可以根据上述内容进行适当地变型，而不仅限于上述附图3的记载。
在一些实施例中，该终端设备可以是包括普通或能力增强终端设备(以下简称第一类终端设备)或能力降低终端设备(RedCap UE，以下简称第二类终端设备)，服务小区可以是普通状态的服务小区，或者是进入节能状态的服务小区，本申请实施例并不以此作为限制。
在一些实施例中，网络设备可以向终端设备发送主信息块(Master information block，MIB)，MIB中包括系统信息类型一(System information block1，SIB1)相关的配置，该配置包括控制资源集合0(control resource set 0，CORESET#0)配置和搜索空间0(Search space 0，SS#0)配置，终端设备根据控制资源集合0和搜索空间0确定PDCCH监听时刻(PDCCH monitoring occasions)，并在该监听时刻监听(monitor)PDCCH，进而根据该PDCCH指示的物理下行共享信道(PDSCH)信息获取SIB1。在SIB1中包括初始下行部分带宽(initial BWP)的配置信息，此外，系统信息还可以包括SIB2,SIB3,SIB4等，具体可以参考现有技术，此处不再赘述。
在一些实施例中，第一参考信号为CD-SSB，第二参考信号为NCD-SSB或至少 包含同步信号SS的参考信号。其中，CD-SSB指的是用于MIB消息中指示调度SIB1的PDCCH的时频资源位置的SSB，终端设备通过CD-SSB可接收小区的SIB1；NCD-SSB指的是MIB消息中不包含调度SIB1的PDCCH时频资源位置指示的SSB。SSB可以包括主同步信号(Primary Synchronization Signal，PSS)，辅同步信号(Secondary Synchronization Signal，SSS)，和/或物理层广播信道(Physical Broadcast Channel，PBCH)。
例如，为了使终端设备(例如第二类终端设备)不用切换频率，使用第二参考信号进行测量，网络设备可以发送用于使用服务小区的第二参考信号进行小区选择或重选的相关信息，该第一参考信号为CD-SSB，该第二参考信号为NCD-SSB。又例如，在服务小区不发送第一参考信号的情况下，为了终端设备能选择到该小区或在该小区中进行小区重选，网络设备可以发送用于使用该小区的第二参考信号进行小区选择或重选的相关信息，该第一参考信号为CD-SSB，该第二参考信号至少包含同步信号。此处仅为示例说明，本申请实施例并不以此为限制。
以下分别针对小区选择场景，同频小区选择场景，异频小区选择场景进行示例说明。
(一)针对小区选择
在一些实施例中，在301中，该终端设备通过服务小区的SIB1接收网络设备发送的第一相关信息；该第一相关信息包括用于使用该服务小区的第二参考信号进行小区选择的相关信息。在302中，该终端设备使用该服务小区的第二参考信号进行小区选择的测量，根据测量结果以及该第一相关信息进行小区选择。因此，终端设备不需要将射频接收机调整到第一参考信号(CD-SSB)的频率，也就是说不需要使用第一参考信号(CD-SSB)进行小区选择的测量。例如，该终端设备可以基于第二参考信号进行小区选择的测量，不用跳回到第一参考信号所在的频率，也就是说不需要使用第一参考信号(CD-SSB)进行小区选择的测量。另外，终端设备也可以在服务小区不发送第一参考信号时(例如节能小区)，使用该小区的第二参考信号进行小区选择的测量。
在一些实施例中，服务小区可以同时支持终端设备使用第一参考信号进行小区选择的测量以及使用第二参考信号进行小区选择的测量。在终端设备进行小区选择时，如果终端设备检测到第一参考信号，则使用第一参考信号进行小区选择的测量；在终 端设备检测到第二参考信号时，使用第二参考信号进行小区选择的测量。
例如，该第一相关信息包括以下至少一种配置：该服务小区的最低要求接收功率水平(dBm)q rxlevmin，搜索高优先级PLMN要求的对q rxlevmin的偏移q rxlevminoffset，该服务小区的最低要求质量水平(dB)q qualmin，搜索高优先级PLMN要求的对q qualmin的偏移q qualminoffset。
在一些实施例中，终端设备可以被配置特定的第一相关信息，或者终端设备还可以将该用于使用第一参考信号进行小区选择的相关信息作为该第一相关信息。
在一些实施例中，该第一相关信息可以重用用于使用第一参考信号进行小区选择的相关信息。例如，在第一参考信号和第二参考信号的发送功率，和/或覆盖相同时，为了节省信令开销，网络设备可以不显示配置SIB1中的第一相关信息，该第一相关信息可以重用用于使用第一参考信号进行小区选择的相关信息。也就是说，在SIB1消息中将用于使用第一参考信号进行小区选择的相关信息作为该第一相关信息。
在一些实施例中，终端设备可以被配置特定的第一相关信息，也即网络设备可以在SIB1中显示配置第一相关信息。
例如，该SIB1使用抽象语法标记ASN.1数据格式可以表示为：
Figure PCTCN2022070928-appb-000001
其中，信息元cellSelectionInfo为用于使用第一参考信号进行小区选择的相关信息，信息元cellSelectionInfo-v180为新引入的第一相关信息。信息元cellSelectionInfo-v180是可选存在的，例如，在该服务小区发送第二参考信号(如NCD-SSB)时存在，当该信息元存在时终端设备可使用第二参考信号进行小区选择。cellSelectionInfo-v180中的q-RxLevMin,q-RxLevMinOffset,q-QualMin,q-QualMinOffset参数也是可选存在的。例如，当这些参数不存在时，可以将cellSelectionInfo中的q-RxLevMin,q-RxLevMinOffset,q-QualMin,q-QualMinOffset的值重用于cellSelectionInfo-v180中的q-RxLevMin,q-RxLevMinOffset,q-QualMin,q-QualMinOffset的值，也就是说，网络设备可以不用显示配置第一相关信息(即终端设备还可以将该用于使用第一参考信号进行小区选择的相关信息作为该第一相关信息)，这样，当使用第一参考信号和使用第二参考信号进行小区选择的相关信息相同时，可以节省信令开销。又例如，cellSelectionInfo-v180中的q-RxLevMin,q-RxLevMinOffset,q-QualMin,q-QualMinOffset也可以存在，也就是说，网络设备可以显示配置第一相关信息(即终端设备可以被配置特定的第一相关信息)。
需要说明的是，在SIB1中不包含信息元cellSelectionInfo-v180时，表示该服务小区不支持终端设备使用第二参考信号进行同频小区选择的测量，在SIB1中同时包含信息元cellSelectionInfo和信息元cellSelectionInfo-v180时，服务小区可以同时支持终端设备使用第一参考信号进行同频小区选择的测量以及使用第二参考信号进行同频小区选择的测量。
在一些实施例中，在302中，该终端设备使用该服务小区的第二参考信号进行小区选择的测量，得到测量结果(例如包括第二参考信号的接收质量等)，根据该测量结果以及该第一相关信息判断是否满足小区选择的条件，以完成小区选择过程，以下详细说明。
例如，使用上述第一相关信息和测量结果计算表示小区质量的参数值，例如Srxlev和Squal，在该参数值不满足预定条件(S标准)时，确定该服务小区或服务小区所在的频率不是小区选择的候选小区和/或候选频率，否则确定该服务小区或服务小区所在的频率是小区选择的候选小区和/或候选频率。
例如，该S标准为:Srxlev>0以及Squal>0
Srxlev＝Q rxlevmeas–(Q rxlevmin+Q rxlevminoffset)–P compensation-Qoffset temp；
Squal＝Q qualmeas–(Q qualmin+Q qualminoffset)-Qoffset temp
其中，Srxlev表示小区选择接收水平值，Squal表示小区选择质量，Qoffset temp表示对小区临时应用的偏移量，Q rxlevmeas表示使用第二参考信号测量到的小区接收功率值，P compensation表示上行和下行功率之间的补偿，与小区配置的最大发送功率p-Max有关，Q qualmeas表示使用第二参考信号测量到的小区质量。进而，根据候选小区和/或候选频率选择一个合适的(suitable)小区，作为终端设备选择的小区，以完成小区选择过程。
(二)针对同频小区重选
在一些实施例中，在301中，该终端设备通过该服务小区的SIB2和/或SIB3接收网络设备发送的第二相关信息；该第二相关信息包括用于使用该服务小区的第二参考信号进行同频小区重选的相关信息。在302中，该终端设备使用该服务小区的第二参考信号进行小区重选的测量，根据测量结果以及该第二相关信息进行同频小区重选。因此，不需要将射频接收机调整到第一参考信号(CD-SSB)的频率，也就是说不需要使用第一参考信号(CD-SSB)进行同频小区重选的测量。例如，该终端设备可以是空闲/非激活状态的终端设备，驻留在服务小区的第二参考信号频率上的终端设备不用跳回到第一参考信号所在的频率，也就是说不需要使用第一参考信号(CD-SSB)进行同频小区重选的测量。另外，终端设备可以在服务小区不发送第一参考信号时(例如节能小区)，使用第二参考信号进行同频小区重选的测量。
在一些实施例中，服务小区可以同时支持终端设备使用第一参考信号进行同频小区重选的测量以及使用第二参考信号进行同频小区重选的测量，在终端设备进行小区重选时，如果终端设备检测到第一参考信号，则使用第一参考信号进行小区重选的测量，在终端设备检测到第二参考信号时，使用第二参考信号进行小区重选的测量。
图4是使用第一参考信号的同频和异频测量示意图，图5是使用第二参考信号的同频和异频测量示意图，如图4和5所示，一个频率对于服务小区的第二参考信号来说是同频测量，而同样的频率对于该服务小区的第一参考信号来说是异频测量。
例如，该第二相关信息包括以下至少一种配置：用于同频测量的时间窗配置SMTC,
在同频测量时间窗内测量的参考信号集合SSB-ToMeasure,
终端设备是否可以通过服务小区的定时获得同频邻小区的参考信号索引的指示 信息deriveSSB-IndexFromCell，
同频邻小区的信号需好于服务小区的时间间隔Treselection,
用于同频邻小区的最低要求接收功率水平(dBm)Q rxlevmin,
用于同频邻小区的最低要求质量水平(dB)Q qualmin,
用于同频小区重选的终端设备最大发送功率(dBm)p-Max,
启动同频测量的服务小区接收功率水平阈值(dBm)S IntraSearchP,
启动同频测量的服务小区接收质量阈值(dB)S IntraSearchQ，
同频邻小区列表IntraFreqNeighCellList,
同频邻小区黑名单intraFreqBlackCellList,
同频邻小区白名单intraFreqWhiteCellList
例如，SIB2中可以承载第二相关信息中的同频邻小区的信号需好于服务小区的时间间隔Treselection,用于同频邻小区的最低要求接收功率水平(dBm)Q rxlevmin,用于同频邻小区的最低要求质量水平(dB)Q qualmin,用于同频小区重选的终端设备最大发送功率(dBm)p-Max,启动同频测量的服务小区接收功率水平阈值(dBm)S IntraSearchP,启动同频测量的服务小区接收质量阈值(dB)S IntraSearchQ。
在一些实施例中，终端设备可以被配置特定的上述SIB2中的该部分第二相关信息，或者终端设备还可以将该用于使用第一参考信号进行同频小区重选的相关信息作为该第二相关信息。
在一些实施例中，该SIB2中的第二相关信息可以重用用于使用第一参考信号进行同频小区重选的相关信息。例如，在第一参考信号和第二参考信号的发送功率，和/或覆盖相同时，为了节省信令开销，网络设备可以不显示配置SIB2中的第二相关信息，该第二相关信息可以重用用于使用第一参考信号进行同频小区重选的相关信息。也就是说，在SIB2中将用于使用第一参考信号进行同频小区重选的相关信息作为该第二相关信息。
在一些实施例中，终端设备可以被配置特定的SIB2中的该部分第二相关信息，也即网络设备可以在SIB2中显示配置第二相关信息。
例如，SIB2中可以承载显示配置的第二相关信息包括：用于同频测量的时间窗配置SMTC,在同频测量时间窗内测量的参考信号集合SSB-ToMeasure,终端设备是否可以通过服务小区的定时获得同频邻小区的参考信号索引的指示信息 deriveSSB-IndexFromCell。
在一些实施例中，由于服务小区的第一参考信号和第二参考信号的频点不同，因此针对第一参考信号和第二参考信号的同频小区的频点是不同的。该部分第二相关信息不能重用用于使用第一参考信号进行同频小区重选的相关信息，只能在SIB2中显示配置。
例如，SIB3中可以承载第二相关信息中的同频邻小区列表IntraFreqNeighCellList,同频邻小区黑名单intraFreqBlackCellList,同频邻小区白名单intraFreqWhiteCellList。
在一些实施例中，终端设备可以被配置特定的上述SIB3中的该部分第二相关信息，或者，终端设备还可以将该用于使用第一参考信号进行同频小区重选的相关信息作为该SIB3中的第二相关信息。
在一些实施例中，该SIB3中的第二相关信息可以重用用于使用第一参考信号进行同频小区重选的相关信息。例如，在第一参考信号和第二参考信号的发送功率，和/或覆盖相同时，为了节省信令开销，网络设备可以不显示配置SIB3中的第二相关信息，该第二相关信息可以重用用于使用第一参考信号进行同频小区重选的相关信息。也就是说，在SIB3中将用于使用第一参考信号进行同频小区重选的相关信息作为该部分第二相关信息。
在一些实施例中，终端设备可以被配置特定的SIB3中该部分第二相关信息，也即网络设备可以显示配置SIB3中的第二相关信息。
在一些实施例中，该方法还可以包括(未图示)该终端设备通过该服务小区的SIB2接收网络设备发送的公共信息，该公共信息用于使用该服务小区的第一参考信号进行小区重选，或用于使用该服务小区的第二参考信号进行小区重选。其中，该公共信息包括以下至少一种配置：为了得到小区的测量结果使用的波束的个数，为了得到小区的测量结果要求的最少波束的个数，可选择的小区的R值范围，该服务小区的R值迟滞量。对于上述公共信息来说，既适用于使用该服务小区的第一参考信号进行小区重选，也适用于使用该服务小区的第二参考信号进行小区重选。

其中，信息元cellReselectionInfoCommon为上述公共信息，也就是说，对于这部分公共信息，无需为这些信息引入针对第二参考信号的新的信息元。信息元intraFreqCellReselectionInfo为用于使用第一参考信号进行同频小区重选的相关信息，信息元intraFreqCellReselectionInfo-v180为新引入的第二相关信息。信息元intraFreqCellReselectionInfo-v180是可选存在的，例如，在该服务小区发送第二参考信号(如NCD-SSB)时存在，当该信息元存在时终端设备可使用第二参考信号进行同频小区选择。信息元intraFreqCellReselectionInfo-v180中的参数是可选存在的。例如，当这些参数不存在时，可以将intraFreqCellReselectionInfo中的部分信息的值重用于信息元intraFreqCellReselectionInfo-v180中的相应第二相关信息，例如，intraFreqCellReselectionInfo中的t-ReselectionNR,q-RxLevMin,q-QualMin,p-Max,s-IntraSearchP,s-IntraSearchQ的值重用intraFreqCellReselectionInfo-v180中的t-ReselectionNR,q-RxLevMin,q-QualMin,p-Max,s-IntraSearchP,s-IntraSearchQ的值。也就是说，网络可以不用显示配置这部分第二相关信息，这样，当使用第一参考信号和使用第二参考信号进行同频小区重选的信息相同时，可以节省信令开销。又例如，intraFreqCellReselectionInfo-v180中的t-ReselectionNR,q-RxLevMin,q-QualMin,p-Max,s-IntraSearchP,s-IntraSearchQ也可以存在，也就是说，网络设备可以显示配置这部分第二相关信息。
其中，信息元intraFreqCellReselectionInfo-v180中的部分第二相关信息的值不可以重用信息元intraFreqCellReselectionInfo的对应信息的值，包括intraFreqCellReselectionInfo-v180中的SSB-ToMeasure,deriveSSB-IndexFromCell，SMTC等。网络设备为其配置特定值，也即显示配置intraFreqCellReselectionInfo-v180中的SSB-ToMeasure,deriveSSB-IndexFromCell，SMTC的值。
需要说明的是，在SIB2中不包含信息元intraFreqCellReselectionInfo-v180时，表 示该服务小区不支持终端设备使用第二参考信号进行同频小区重选的测量，在SIB2中同时包含信息元intraFreqCellReselectionInfo和信息元intraFreqCellReselectionInfo-v180时，服务小区可以同时支持终端设备使用第一参考信号进行同频小区重选的测量以及使用第二参考信号进行同频小区重选的测量。
另外，UE使用针对第一参考信号的同名信息元的值作为第二相关信息的情况下，在SIB2中，如果没有针对第一参考信号的同名信息元，UE使用对应该同名信息元的默认值进行使用第二参考信号的同频小区重选的测量，例如，intraFreqCellReselectionInfo-v180中的q-QualMin不存在，如果intraFreqCellReselectionInfo中对应的q-QualMin的信息元也不存在，则使用对应q-QualMin的默认值(负无穷大)进行使用第二参考信号的同频小区重选的测量。
例如，该SIB3使用抽象语法标记ASN.1数据格式可以表示为：
Figure PCTCN2022070928-appb-000005
其中，信息元intraFreqNeighCellList，intraFreqBlackCellList，intraFreqWhiteCellList为用于使用第一参考信号进行同频小区重选的相关信息，信息元intraFreqNeighCellListNCD-r18，intraFreqBlackCellList-r18，intraFreqWhiteCellList-r18为第二相关信息。这些参数是可选存在的，例如，当这些参数不存在时，信息元intraFreqNeighCellListNCD-r18，intraFreqBlackCellList-r18，intraFreqWhiteCellList-r18 的重用信息元intraFreqNeighCellList，intraFreqBlackCellList，intraFreqWhiteCellList的值，这样可以节省信令开销。又例如，intraFreqNeighCellListNCD-r18，intraFreqBlackCellList-r18，intraFreqWhiteCellList-r18也可以存在，也即网络设备显示配置intraFreqNeighCellListNCD-r18，intraFreqBlackCellList-r18，intraFreqWhiteCellList-r18的特定值。
当UE重用针对第一参考信号的同名信息元的值作为SIB3中的上述第二相关信息的情况下，在SIB3中，如果没有针对第一参考信号的同名信息元，且该信息元为Need R，则UE认为网络设备没有配置用于使用第二参考信号的同频小区重选的相关信息。
(三)针对异频小区重选
在一些实施例中，在301中，该终端设备通过该服务小区的SIB2和/或SIB4接收网络设备发送的第三相关信息；该第三相关信息包括用于使用该服务小区的第二参考信号进行异频小区重选的相关信息。
在302中，该终端设备使用该服务小区的第二参考信号进行小区重选的测量，根据测量结果以及该第三相关信息进行异频小区重选。因此，不需要将射频接收机调整到第一参考信号(CD-SSB)的频率，也就是说不需要使用第一参考信号(CD-SSB)进行异频小区重选的测量。例如，该终端设备可以是空闲/非激活状态的终端设备，驻留在服务小区的第二参考信号频率上的终端设备不用跳回到第一参考信号所在的频率，也就是说不需要使用第一参考信号(CD-SSB)进行异频小区重选的测量。另外，终端设备可以在服务小区不发送第一参考信号时(例如节能小区)，使用第二参考信号进行异频小区重选的测量。
在一些实施例中，服务小区可以同时支持终端设备使用第一参考信号进行异频小区重选的测量以及使用第二参考信号进行异频小区重选的测量。在终端设备进行异频小区重选时，如果终端设备检测到第一参考信号，则使用第一参考信号进行小区重选的测量，在终端设备检测到第二参考信号时，使用第二参考信号进行小区重选的测量。
例如，该第三相关信息包括以下至少一种配置：
启动低优先级异频测量的服务小区接收功率水平阈值(dBm)S nonIntraSearchP，
启动低优先级异频测量的服务小区接收质量阈值(dB)S nonIntraSearchQ，
针对低优先级异频小区重选的服务小区接收水平阈值(dBm)Thresh Serving,LowP，
针对低优先级异频小区重选的服务小区接收质量阈值(dB)Thresh Serving,LowQ，
用于特定频率小区重选的邻区接收水平阈值Thresh X,P，
用于特定频率小区重选的邻区接收质量阈值Thresh X,Q，
用于特定频率邻小区的最低要求接收功率水平(dBm)Q rxlevmin，
用于特定频率邻小区的最低要求质量水平(dB)Q qualmin，
用于特定频率小区重选的终端设备最大发送功率(dBm)p-Max,
用于特定频率的黑名单小区interFreqBlackCellList，
用于特定频率小区的绝对优先级cellReselectionPriority，
用于特定频率的邻小区列表interFreqCarrierFreqList。
例如，SIB2中可以承载第三相关信息中的启动低优先级异频测量的服务小区接收功率水平阈值(dBm)S nonIntraSearchP，启动低优先级异频测量的服务小区接收质量阈值(dB)S nonIntraSearchQ，针对低优先级异频小区重选的服务小区接收水平阈值(dBm)Thresh Serving,LowP，针对低优先级异频小区重选的服务小区接收质量阈值(dB)Thresh Serving,LowQ。
在一些实施例中，终端设备可以被配置特定的上述SIB2中的该部分第三相关信息，或者终端设备还可以将该用于使用第一参考信号进行异频小区重选的相关信息作为该SIB2中的第三相关信息。用于使用第一参考信号进行异频小区重选的相关信息和该第三相关信息是针对相同频率的信息。
在一些实施例中，该SIB2中的第三相关信息可以重用用于使用第一参考信号进行异频小区重选的相关信息。例如，在第一参考信号和第二参考信号的发送功率，和/或覆盖相同时，为了节省信令开销，网络设备可以不显示配置SIB2中的第三相关信息，该第三相关信息可以重用用于使用第一参考信号进行异频小区重选的相关信息。也就是说，在SIB2中将用于使用第一参考信号进行异频小区重选的相关信息作为该第三相关信息。
在一些实施例中，终端设备可以被配置特定的SIB2中的该部分第三相关信息，也即网络设备可以在SIB2中显示配置第三相关信息。
例如，该SIB2使用抽象语法标记ASN.1数据格式可以表示为：

其中，信息元cellReselectionServingFreqInfo为用于使用第一参考信号进行异频小区重选的相关信息，信息元cellReselectionServingFreqInfo-r18为新引入的第三相关信息。信息元cellReselectionServingFreqInfo-r18是可选存在的，例如，在该服务小区发送第二参考信号(如NCD-SSB)时存在，当该信息元存在时终端设备可使用第二参考信号进行异频小区选择。cellReselectionServingFreqInfo-r18中的参数是可选的。 例如，当这些参数不存在时，可以将cellReselectionServingFreqInfo中的部分信息的值重用于信息元cellReselectionServingFreqInfo-r18中的相应第三相关信息，例如，cellReselectionServingFreqInfo中的S nonIntraSearchP，S nonIntraSearchQ，Thresh Serving,LowP，Thresh Serving,LowQ的值重用cellReselectionServingFreqInfo-r18中的S nonIntraSearchP，S nonIntraSearchQ，Thresh Serving,LowP，Thresh Serving,LowQ的值。也就是说，网络可以不用显示配置这部分第三相关信息，这样可以节省信令开销。又例如，cellReselectionServingFreqInfo-r18中的S nonIntraSearchP，S nonIntraSearchQ，Thresh Serving,LowP，Thresh Serving,LowQ可以存在，也就是说，网络设备可以显示配置这部分第三相关信息。
需要说明的是，在SIB2中不包含信息元cellReselectionServingFreqInfo-r18时，表示该服务小区不支持终端设备使用第二参考信号进行异频小区重选的测量。在SIB2中同时包含信息元cellReselectionServingFreqInfo和信息元cellReselectionServingFreqInfo-r18时，服务小区可以同时支持终端设备使用第一参考信号进行异频小区重选的测量以及使用第二参考信号进行异频小区重选的测量。
另外，UE使用针对第一参考信号的同名信息元的值作为第三相关信息的情况下，在SIB2中，如果没有针对第一参考信号的同名信息元，UE使用对应该同名信息元的默认值进行使用第二参考信号的异频小区重选的测量。例如，cellReselectionServingFreqInfo-r18中的S nonIntraSearchP不存在，如果cellReselectionServingFreqInfo中对应的S nonIntraSearchP的信息元也不存在，则使用对应S nonIntraSearchP的默认值(无穷大)进行使用第二参考信号的异频小区重选的测量。
例如，SIB4中可以承载第三相关信息中的用于特定频率小区重选的邻区接收水平阈值Thresh X,P，用于特定频率小区重选的邻区接收质量阈值Thresh X,Q，用于特定频率小区重选的终端设备最大发送功率(dBm)p-Max,用于特定频率邻小区的最低要求接收功率水平(dBm)Q rxlevmin，用于特定频率邻小区的最低要求质量水平(dB)Q qualmin，用于特定频率的黑名单小区interFreqBlackCellList，用于特定频率小区的绝对优先级cellReselectionPriority，用于特定频率的邻小区列表interFreqCarrierFreqList。
在一些实施例中，针对相同邻区频率的第三相关信息，终端设备可以被配置特定的上述SIB4中的该部分第三相关信息，或者终端设备还可以将该用于使用第一参考信号进行异频小区重选的相关信息作为该SIB4中的第三相关信息。
在一些实施例中，该SIB4中的第三相关信息可以重用用于使用第一参考信号进 行异频小区重选的相关信息。例如，在第一参考信号和第二参考信号的发送功率，和/或覆盖相同时，为了节省信令开销，网络设备可以不显示配置SIB4中的第三相关信息，该第三相关信息可以重用用于使用第一参考信号进行异频小区重选的相关信息。也就是说，在SIB4中将用于使用第一参考信号进行异频小区重选的相关信息作为该第三相关信息。
在一些实施例中，终端设备可以被配置特定的SIB4中的该部分第三相关信息，也即网络设备可以显示配置SIB4中的第三相关信息。。
例如，该SIB4使用抽象语法标记ASN.1数据格式可以表示为：

其中，以信息元InterFreqCarrierFreqList为例，InterFreqCarrierFreqList为用于使用第一参考信号进行异频小区重选的相关信息，信息元InterFreqCarrierFreqList-v180为新引入的第三相关信息。信息元InterFreqCarrierFreqList-v180是可选存在的，例如，在该服务小区发送第二参考信号(如NCD-SSB)时存在，当该信元存在时终端设备可使用第二参考信号进行异频小区选择。InterFreqCarrierFreqInfo-v180中的参数是可选存在的。例如，当这些参数不存在时，可以将InterFreqCarrierFreqInfo中的部分信息的值重用于信息元InterFreqCarrierFreqInfo-v180中的相应第三相关信息。也就是说，网络可以不用显示配置这部分第三相关信息，这样，可以节省信令开销。又例如，可以为InterFreqCarrierFreqInfo-v180中的部分第三相关信息显示配置特定值，具体可以参考前述SIB2，此处不再一一举例。
当UE使用针对第一参考信号的同名信息元的值作为第三相关信息情况下，在SIB4中，如果没有针对第一参考信号的同名信息元，且该信息元为Need R，则UE认为网络设备没有配置用于使用第二参考信号的异频小区重选的相关信息。
在一些实施例中，针对上述(二)和(三)，在302中，该终端设备使用该服务小区的第二参考信号进行同频或异频小区重选的测量，得到测量结果(例如包括第二参考信号的接收质量等)，根据该测量结果以及该第二/三相关信息判断是否满足小区重选的条件，以完成小区重选过程，以下详细说明。
例如，在小区重选过程中，对服务小区进行测量，以及判断是否对邻小区进行测量，针对同频：判断服务小区质量是否高于门限S IntraaSearchP或门限S IntraaSearchQ；在高于门限时，不执行邻小区的同频测量，否则执行同频测量；针对异频，如果异频小区或频率优先级高于当前服务小区或频率，终端设备执行对高优先级的异频测量，如果异频小区或频率优先级低于或等于当前服务小区或频率，判断服务小区质量是否高于门限S nonIntraSearchP或S nonIntraSearchQ；在高于门限时，不执行邻小区(低优先级)的异频测量，否则执行异频测量；上述S nonIntraSearchP针对小区质量是参考信号接收功率(RSRP)对 应的门限，S nonIntraSearchQ针对小区质量是参考信号接收质量(RSRQ)对应的门限；在测量后需要进行重选评估，
针对同频和相同优先级的异频，可以考虑根据测量结果和第二相关信息(或第三相关信息)计算如下R小区排序标准：
服务小区R s＝Q meas,s+Q hyst-Qoffset temp
邻小区R n＝Q meas,n-Qoffset-Qoffset temp。
其中，Qmeas表示测量结果，Qoffset temp表示连接失败时应用的临时小区偏移值。
根据计算结果对小区进行排序，重选最高等级(rank)的小区，如果最高等级的小区是禁止状态(barred)或者由于特定的原因不是合适(suitable)的小区，则不考虑该小区作为小区重选的候选小区，否则，重选该小区。
针对不同优先级的异频：如果在时间段中比当前服务小区或频率重选优先级高的异频上的一个小区的质量高于门限Thresh X,HighP，则执行到该高优先级的频率上的小区的重选或者将该高优先级的频率上的小区作为最好的小区；如果在时间段中比当前服务小区或频率重选优先级低的的异频上的一个小区的质量高于门限Thresh X,LowP且当前服务小区的质量内低于门限Thresh Serving,LowP，则执行到该低优先级的频率上的小区的重选或者将该低优先级的频率上的小区作为最好的小区。如果有多于一个小区满足上述标准，则终端设备可以重选满足上述标准的最高优先级频率上的最高等级(rank)的小区，或者将满足上述标准的最高优先级频率上的最高等级(rank)的小区作为最好的小区。如果根据前述过程得到的重选的小区或最好的小区是禁止状态(barred)或者由于特定的原因不是合适(suitable)的小区，则不考虑该小区作为小区重选的候选小区，否则，重选到该小区。
此外，以上各个实施例仅对本申请实施例进行了示例性说明，但本申请不限于此，还可以在以上各个实施例的基础上进行适当的变型。例如，可以单独使用上述各个实施例，也可以将以上各个实施例中的一种或多种结合起来。
通过上述实施例，网络设备向终端设备发送使用第二参考信号进行小区选择或重选的相关信息。由此，终端设备可以使用该第二参考信号进行小区选择或重选，而无需使用CD-SSB进行小区选择或重选的测量，可以减少UE在不同频率之间的切换，提高传输效率和节能。另外，使得驻留在节能状态的小区(即不发送CD-SSB)的终 端设备也可以进行小区重选的测量，或者，使得终端设备可以选择到一个节能状态的小区。
