Description

一种测量邻区的方法、装置以及终端
本申请要求于2020年4月16日提交国家知识产权局、申请号为202010302295.3、申请名称为“一种测量邻区的方法、装置以及终端”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及终端技术领域，尤其涉及一种测量邻区的方法、装置以及终端。
背景技术
在无线通信系统中，当终端所在服务小区信号质量不佳时，网络会下发同频、异频等测量任务，以便终端由当前服务小区切换到同频邻区或异频邻区。
在新空口(new radio，NR)系统中，终端可以基于同步信号/物理广播信道块(synchronization signal/physical broadcast channel block，SSB)进行邻区测量。为了避免终端进行无用的搜索，网络为终端配置用于进行SSB测量的窗口，即同步信号测量定时配置(synchronization signal/physical broadcast channel measurement time configuration，SMTC)窗。也就是说，终端只需在SMTC窗内进行SSB测量，在SMTC窗外不进行SSB测量，从而节省终端功耗。在一些异频测量的场景中，例如终端只有单个接收通路时，网络还会为终端配置测量间隙(measurement gap)，终端在测量间隙暂停接收服务小区的信号和数据，接收邻区的信号，在STMC窗内进行SSB测量。也就是说，终端需要在测量间隙和STMC窗的交叠窗口进行SSB测量。
然而，由于NR系统中各个小区的SSB的周期和位置均比较灵活以及各个小区的系统帧的定时也可能不同步等，会出现各个小区的SSB、SMTC窗在时域上不对齐的情况，那么终端在网络配置的SMTC窗内，或者在网络配置的SMTC窗和测量间隙的交叠窗口，无法测量到一些邻区的SSB。如此，可能造成终端测量不到信号质量较好的邻区，无法完成小区切换，从而影响业务的连续性。
发明内容
本申请提供的一种测量邻区的方法、装置以及终端，可以使得终端测量到更多的邻区，顺利完成小区切换或顺利添加辅小区等，保证终端业务的连续性。
为了实现上述目的，本申请实施例提供了以下技术方案：
第一方面、提供一种测量邻区的方法，该方法包括：终端接收接入网设备发送的测量配置信息，测量配置信息包括待测量邻区的信息和测量时间窗的信息；测量时间窗的信息包括同步信号测量定时配置SMTC窗或测量间隙；终端在测量时间窗和测量时间窗后的第一时间段内执行邻区测量，其中第一时间段和测量时间窗的总长度大于或等于待测量邻区一个同步信号/物理广播信道块SSB的周期的长度；终端向接入网设备发送待测量邻区的测量报告。
可见，终端根据网络侧配置的测量时间窗的信息，确定在测量时间窗以及测量时间窗后第一时间段内均进行邻区测量。由于测量时间窗以及测量时间窗后第一时间段至少覆盖邻区的一个SSB周期的长度，那么，终端可以便测量到更多邻区，并上报测 量到的更多邻区的测量报告。那么，网络侧可以基于终端更多邻区的测量报告中确定切换后的服务小区或确定辅小区，有利于保持业务的连续性。
一些示例中，若待测量的邻区具有不同的SSB周期时，这里测量时间窗以及测量时间窗后第一时间段的总长度可以大于或等于所有待测量邻区的SSB周期中的最大值。
网络侧配置的测量时间窗具有周期性。终端可以在每个周期内的测量时间窗后都默认确定第一时间段，这样终端可以在测量时间窗和第一时间段内检测到全部的邻区。
可选的，终端也可以在每个周期内，先在测量时间窗内执行邻区测量。如果未测量到邻区，或者未测量到预设数量的邻区，或者测量到的邻区的信号质量不满足预设条件时，再在测量时间窗后确定第一时间段，继续执行邻区测量。也就是说，终端在每个测量时间窗的周期内，都先根据测量时间窗的测量情况，确定是否扩展本周期内的第一时间段。
可选的，终端还可以第一个周期内，先在测量时间窗内执行邻区测量。如果未测量到邻区，或者未测量到预设数量的邻区，或者测量到的邻区的信号质量不满足预设条件时，再确定第一时间段，继续执行邻区测量。而后，终端在后续的测量时间周期内，可直接确定第一时间段，在测量时间窗和第一时间段内都进行邻区测量。也就是说，终端根据第一个测量时间窗的周期内的测量情况，确定本周期内以及后续周期内是否扩展第一时间段。
一种可能的实现方式中，该方法还包括：终端在第一时间段内执行邻区测量的过程中，终端还接收服务小区的数据。
一种可能的实现方式中，终端在第一时间段内执行邻区测量的过程中，终端还接收服务小区的数据，包括：当待测量邻区为同频邻区、第一异频邻区和第二异频邻区中任一项时，终端使用第一射频接收通道接收服务小区的数据，以及同频邻区或第一异频邻区或第二异频邻区的SSB；其中，第一射频接收通道为终端未执行邻区测量时接收服务小区的数据使用的射频接收通道；第一异频邻区用于测量SSB频点位于服务小区已激活的BWP内；第二异频邻区用于测量的SSB与服务小区的小区定义SSB的中心频率相同，但第二异频邻区的子载波间隔与服务小区的子载波间隔不同。
可以理解的是，当待测量邻区为同频邻区、第一异频邻区或第二异频邻区时，这些邻区用于测量的SSB均位于服务小区已激活的BWP内。也就是说，终端能够同时接收到服务小区和这些邻区的信号，即包括服务小区发送的数据以及邻区发送的SSB。现有技术中，在第一时间段内，终端并不对接收到的邻区的SSB进行处理。而本申请实施例需对邻区的SSB进行处理。
一种可能的实现方式中，该方法还包括：当待测量邻区为同频邻区时，终端基于同频邻区和服务小区的物理小区标识PCI分离通过第一射频接收通道接收到的服务小区的数据和同频邻区的SSB；当待测量邻区为第一异频邻区时，终端基于第一异频邻区和服务小区的频率和物理小区标识PCI分离通过第一射频接收通道接收到的服务小区的数据和第一异频邻区的SSB；当待测量邻区为第二异频邻区时，终端基于第二异频邻区和服务小区的物理小区标识PCI和子载波间隔分离通过第一射频接收通道接收到的服务小区的数据和第二异频邻区的SSB。由此，提供一种终端对同时接收到的邻区的信号和服务小区的信号进行分离的方法。
一种可能的实现方式中，终端在第一时间段内执行邻区测量的过程中，终端还接收服务小区的数据，包括：当待测量邻区为第三异频邻区时，终端使用第二射频接收通道接收服务小区的数据，以及使用第三射频接收通道接收第三异频邻区的SSB；其中，第二射频接收通道为终端未执行邻区测量时接收服务小区的数据使用的射频接收通道；或者，第二射频接收通道和第三射频接收通道为终端未执行邻区测量时接收服务小区的数据使用的射频接收通道；第三异频邻区用于测量SSB频点位于服务小区已激活的BWP外。
也就是说，如果终端具有同时接收第三异频小区和服务小区的信号的能力，则在第一时间段内开启新的射频接收通道用于接收第三异频小区的信号。与此同时，原来使用的射频接收通道用于接收服务小区的信号。此时，原来使用的射频接收通道为第二射频接收通道，新开启的射频接收通道为第三射频接收通道。如果终端不具有同时接收第三异频小区和服务小区的信号的能力，则在第一时间段内从原来使用的射频接收通道中借用一部分通道，用于接收第三异频小区的SSB，剩余的通道用于接收服务小区的信号。此时，原来使用的射频接收通道为第二射频接收通道和第三射频频接收通道。
由此，终端即可测量到更多的第三异频邻区，又可避免因减少用于接收服务小区数据的射频接收通道数可能带来的误码，提升终端接收服务小区的数据的正确性。
一种可能的实现方式中，终端使用第二射频接收通道接收服务小区的数据，以及使用第三射频接收通道接收第三异频邻区的SSB之前，该方法还包括：终端在接收到接入网设备发送的测量配置信息之后，向接入网设备发送第一秩，第一秩为第二秩和预设秩的最小值；第二秩为终端根据信道状态信息确定的秩，预设秩小于终端具有的射频接收通道的数量。
换言之，终端通过上报不大于预设秩的方法，降低网络侧调用多进多出(multiple-in multiple-out，MIMO)的层数。这样，网络侧发送的数据流的流数小于终端具有的射频接收通道数，那么终端剩余的射频接收通道可用于接收第二类异频小区的信号。由此，提供一种终端在第一时间段内同时接收服务小区的数据以及第三异频邻区的SSB的方法。
一种可能的实现方式中，该方法还包括：终端接收到接入网设备发送的去测量配置指示后，终端向接入网设备发送第二秩。由此，网络侧可以恢复调用MIMO的层数。
第二方面、提供一种测量邻区的通信系统，包括：接入网设备和终端，接入网设备，用于向终端发送测量配置信息，测量配置信息包括待测量邻区的信息和测量时间窗的信息；测量时间窗的信息包括同步信号测量定时配置SMTC窗或测量间隙；接入网设备，还用于向终端发送第一BWP配置，第一BWP配置指示的MIMO层数小于终端支持的最大的MIMO层数；终端，用于在测量时间窗内使用第一射频接收通道和第二射频接收通道接收待测量邻区的SSB；其中，第一射频接收通道和第二射频接收通道为终端未执行邻区测量时接收服务小区的数据使用的射频接收通道；终端，还用于在测量时间窗后的第一时间段内根据第一BWP配置使用第一射频接收通道接收服务小区的数据，以及使用第二射频接收通道接收测量邻区的SSB；其中第一时间段和测量时间窗的总长度大于或等于待测量邻区一个同步信号/物理广播信道块SSB周期的 长度；终端，用于向接入网设备发送待测量邻区的测量报告。
可见，网络侧通过修改终端的BWP配置，降低终端可支持的最大MIMO的层数，从而减少终端接收服务小区数据的所需的射频接收通道数，剩余的射频接收通道可用于接收第二类异频邻区的信号。进而，实现终端在第一时间段内可以同时接收服务小区的发送的数据和异频小区发送的SSB。由此终端即可测量到更多的邻区，又可避免因减少用于接收服务小区数据的射频接收通道数量可能带来的误码，提升终端接收服务小区的数据的正确性。
一种可能的实现方式中，接入网设备，还用于向终端发送去测量配置指示后，向终端发送第二BWP配置，第二BWP配置指示的MIMO层数等于终端支持的最大的MIMO层数；终端，还用于根据第二BWP配置，使用第一射频接收通道和第二射频接收通道接收接入网设备发送的服务小区的数据。

一种可能的实现方式中，该方法还包括：终端接收接入网设备向终端发送的去测量配置指示和第二BWP配置，第二BWP配置指示的MIMO层数等于终端支持的最大的MIMO层数；终端根据第二BWP配置使用第一射频接收通道和第二射频接收通道接收服务小区的数据。

其中，上述终端100为接入上述通信系统，且具有无线收发功能的终端或可设置于该终端的芯片(系统)或其他部件或组件。该终端100也可以称为用户装置、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。本申请的实施例中的用户设备可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、电视、投影仪、智能手表、穿戴式小配件(例如，智能腕表、T恤、项链或鞋)、媒体(例如，音乐和/或视频)播放器、游戏机、游戏控制台和控制器、电子书(ebook)阅读器、虚拟现实(virtual reality，VR)用户设备、增强现实(augmented reality，AR)用户设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端、车载终端、具有终端功能的RSU等。本申请的用户设备还可以是作为一个或多个部件或者单元而内置于车辆的车载模块、车载模组、车载部件、车载芯片或者车载单元，车辆通过内置的所述车载模块、车载模组、车载部件、车载芯片或者车载单元可以实施本申请提供的技术方案。此外，终端100 可具有任意合适的操作系统(OS)，例如Android、iOS、Windows、Linux、Unix等。
上述接入网设备200为位于上述通信系统的网络侧，且具有无线收发功能的设备或可设置于该设备的芯片(系统)或部件或组件。该接入网设备包括但不限于：无线保真(wireless fidelity，WiFi)系统中的接入点(access point，AP)，如家庭网关、路由器、服务器、交换机、网桥等，演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(base station controller，BSC)、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)，无线中继节点、无线回传节点、传输点(transmission and reception point，TRP或者transmission point，TP)等，还可以为5G，如，新空口(new radio，NR)系统中的gNB，或，传输点(TRP或TP)，5G系统中的基站的一个或一组(包括多个天线面板)天线面板，或者，还可以为构成gNB或传输点的网络节点，如基带单元(BBU)，或，分布式单元(distributed unit，DU)、具有基站功能的路边单元(road side unit，RSU)等。
在一些实施例中，一个终端100可以与一个接入网设备200通信，也可以同时与多个接入网设备200通信。例如，该终端100可以与单连接(single connectivity)场景下的接入网设备200上的一个小区，即服务小区(serving cell)进行通信。再例如，该终端100也可以同时与一个接入网设备200上的多个小区，如载波聚合(carrier aggregation，CA)场景下主小区(primary cell，PCell)，以及一个或多个辅小区(sendary cell，SCell)进行通信。又例如，该终端100还可以同时与多个接入网设备200上的多个小区，如双连接(dual connectivity，DC)场景下的主节点(main node，MN)上的主小区组(main cell group，MCG)和辅节点(secondary node，SN)上的辅小区组(secondary cell group，SCG)进行通信。其中，MCG包括一个PCell，SCG包括一个主辅小区(primary secondary cell，PSCell)。可选地，MCG和/或SCG还可以包括一个或多个SCell。应理解，当MCG和/或SCG包括多个服务小区时，同一节点上的不同小区之间可以采用CA方式为终端100提供网络服务。
如图1所示，为终端100提供网络服务的小区为服务小区。例如，服务小区可以为上述单连接场景下的服务小区，或为上述CA或DC场景下的主小区。
一般来讲，根据3GPP协议(例如3GPP TS36.214)的规定,当终端100处于在连接状态(connection)下，终端会周期性或事件性向网络侧上报所测量到的服务小区和邻区的测量报告，根据测量报告，可以完成小区选择、重选及切换等动作。
例如，当终端100所在服务小区信号质量不佳时，或者需要为终端100添加辅小区时，网络会下发同频小区、异频小区等的测量任务，以便终端100基于网络下发的测量信号进行邻区测量。终端将各个邻区的测量结果上报给网络。而后，网络可以根据这些测量结果，确定将终端当前的服务小区切换为信号质量更好的其他邻区，例如邻区1或邻区2，以继续为终端100提供网络服务，保证终端100业务的连续性。或者，网络根据各个邻区的测量结果，为终端100添加信号质量较好的辅小区。需要说明的是，图1所示的服务小区、邻区1和邻区2的覆盖范围仅为说明三个小区的覆盖范围存在交叠区域，并不表示各个小区真实的覆盖区域。
其中，同频小区，是指用于测量的SSB与服务小区的小区定义(cell-defining)SSB具有相同的中心频率(central frequency)和子载波间隔(subcarrier spacing，SCS)。异频小区，是指用于测量的SSB与服务小区的小区定义(cell-defining)SSB的中心频率(central frequency)和子载波间隔(subcarrier spacing，SCS)中至少有一项不同。
上述网络下发的测量信号包括SSB和/或信道状态信息参考信号(channel state information reference signal，CSI-RS)。本文以SSB为例进行说明。一个SSB由新空口同步信号(New radio Synchronization Signal，NR-SS)和新空口物理广播信道(New radio Physical Broadcast Channel，NR-PBCH)两部分组成。NR-SS分为新空口主同步信号(New radio Primary Synchronization Signal，NR-PSS)和新空口辅同步信号(New radio Secondary Synchronization Signal，NR-SSS)两部分。其中，NR-PSS主要用于粗同步，NR-SSS主要用于精同步，以及基于SSB的测量。NR-PBCH，主要用于广播小区级别的系统信息等。在时域上，一个SSB通常集中在5ms内，且协议规定SSB的周期可以为5毫秒(milisecond，ms)、10ms、20ms、40ms、80ms、160ms。
为了节省终端的功耗，网络为终端100配置SMTC窗，指示终端进行SSB测量的时域位置。即，终端在该SMTC窗内进行SSB测量，在该SMTC窗外不进行SSB测量。对于连接态下的同频测量，网络可以为终端在一个频点上配置一个或两个SMTC窗。若配置两个SMTC窗，这两个SMTC窗具有不同的周期，但偏移量和长度相同。
在一些同频测量的场景中，由于各个邻区的SSB的周期可能不同，各个邻区的SSB在无线帧的位置可能不同，各个邻区可能出现时间异步(例如邻区包括时分复用(Time-divisionDuplex，TDD)小区和频分复用(Frequency-division Duplex，FDD)小区)等因素，可能造成小区之间SSB与配置的SMTC不对齐。那么，终端在网络配置的SMTC窗内无法测量到其中一些邻区的SSB。为此，本申请实施例提供一种邻区测量方法，终端可以根据网络配置的SMTC窗(记为第一SMTC窗)确定第二SMTC窗，使得第一SMTC窗和第二SMTC窗覆盖至少一个SSB周期的长度。终端在第一SMTC窗内进行邻区SSB测量，在第二SMTC窗内，终端继续进行邻区SSB测量，且接收服务小区发送的数据。
示例性的，如图2所示，服务小区的中心频点为频点1，假设网络为终端配置的第一SMTC窗为SMTC1，SMTC1的长度为5ms，周期为40ms。假设在当前位置还存在同频小区1至同频小区3。其中，同频小区1和同频小区2的区别在于，两者的SSB在无线帧的位置不同，同频小区1的SSB位于无线帧的前5ms，同频小区2的SSB位于无线帧的后5ms。同频小区1和同频小区3的区别在于，两者的时间不同步，存在帧时序差值(Frame Timing Difference，SFTD)。
由图可见，同频小区1配置的SSB在SMTC1窗内，但同频小区2和同频小区3的SSB均不在SMTC1窗内。也就是说，若终端采用现有技术，仅在网络配置的SMTC1进行邻区测量时，会测量不到同频小区2和同频小区3的SSB。然而，本申请实施例提供的技术方案，终端根据网络配置的SMTC1窗确定SMTC3窗，使得SMTC1和SMTC3窗的总时长(即SMTC2窗的时长)覆盖至少一个SSB周期。例如：各个邻区的SSB的周期均为20ms，SMTC3窗的长度为16ms，SMTC2窗的长度为21ms。并且，除了在原来的SMTC1窗内进行邻区测量外，在SMTC3窗内，终端既保持服务小区的 数据传输，又继续进行邻区测量。这样，终端可以测量到当前全部同频小区的SSB，有利于终端进行小区切换或者添加辅小区，保持业务的连续性。具体的技术方案将在下文详细说明。
对于连接态的异频测量，网络可以为终端在每一个频点上配置一个SMTC窗。一些示例中，网络还会为一个频段配置测量间隙，终端在测量间隙内停止接收服务小区的数据，切换不同的频点进行异频测量。
在一些异频测量的场景中，各个邻区的SSB极可能与网络配置的测量间隙、各个频点配置的SMTC不对齐。那么，终端在网络配置的测量间隙和SMTC窗的交叠窗内无法测量到其中一些邻区的SSB。为此，本申请实施例提供一种邻区测量方法，终端仍然可以根据网络配置的测量间隙(即第一测量间隙)确定第二测量间隙，使得第二测量间隙和第一测量间隙的总长度覆盖至少一个SSB周期的长度。在第一测量间隙内终端进行邻区SSB测量。在第二测量间隙内，终端继续进行邻区SSB测量，且接收服务小区发送的数据。
示例性的，如图3所示，服务小区的中心频点为频点1，假设网络为频点1所在的频段的终端配置的第一测量间隙为GAP1，GAP1的长度为5ms，周期为40ms。假设在当前位置还存在异频小区1至异频小区3。网络会为不同频点配置SMTC窗，例如为异频小区1所在的频点2配置SMTC4窗，为异频小区2所在的频点3配置SMTC5窗，为异频小区3所在的频点4配置SMTC6窗。
由图可见，异频小区1配置的SSB在GAP1窗内，但异频小区2和异频小区3的SSB均不在GAP1窗内。也就是说，若终端采用现有技术，仅在网络配置的GAP1和各个频点的SMTC窗的交叠窗口内进行邻区测量时，会测量不到异频小区2和异频小区3的SSB。然而，本申请实施例提供的技术方案，终端将网络配置的GAP1窗扩展为GAP2窗，GAP2覆盖至少一个SSB周期。例如：各个邻区的SSB的周期均为20ms，GAP2窗的长度扩展为21ms。并且，除了在原来的GAP1内进行邻区测量外，在GAP2中新增加的GAP3窗内，终端既保持接收服务小区的数据，又继续进行邻区测量。这样，终端可以测量到当前全部异频小区的SSB，有利于终端进行小区切换或添加辅小区，保持业务的连续性。具体的技术方案将在下文详细说明。
需要说明的是，本文中的“SMTC窗”和“测量间隙”也可以表达为“时间段”、“时间窗”、“时间间隙”、“时域位置”、“测量窗口”等其他词汇，本申请对此不做限定。
应理解，图1仅为便于理解而示例的简化示意图，该通信系统中还可以包括其他网络设备，和/或，其他终端，图1中未予以画出。
其中，终端100通常包括有天线、射频前端(Front End Module，FEM)、射频处理单元(Radio-Freqncy Integrated Circuits，RFIC)、基带(Baseband Integrated Circuits，BBIC)等组成，其中，RFIC代表终端设备的射频通道能力，例如Rx1，Rx2…RxN代表某个频段的接收通道(例如主集接收通道或分集接收通道)。如图4A所示，提供一种典型的终端100的结构示意图。终端100包括基带处理器103，射频电路102，天线101。
如图4B所示，提供又一种典型的终端100的结构示意图。终端100包括基带处理器、射频处理单元(RFIC)、功率放大器(PA)、滤波器、双工器和天线等。芯片 平台、射频前端和天线构成了终端的无线通信模块。其中，芯片平台包括基带芯片、射频芯片和电源管理芯片等，基带芯片负责物理层算法、高层协议的处理和多模互操作的实现；射频芯片负责射频信号和基带信号之间的相互转换；射频前端模块是连接射频处理单元和天线的必经通路，如图4B所示。它主要包括：功率放大器(PA)，滤波器(Filter)、双工器(Duplexer)或多工器(Multiplexer)、低噪声放大器(LNA)和开关(Switch)或天线调谐模块(ASM)等。一些终端的射频前端架构中，会在天线开关后增设双通器(Diplexer)、连接器(Coupler)等器件。
下面结合附图对本申请实施例提供的技术方案进行详细说明。如图5所示，为本申请实施例提供的一种测量邻区的方法流程示意图，该方法包括：
S501、接入网设备向终端发送测量配置信息。相应地，终端接收接入网设备发送的测量配置信息。
示例性的，终端设备想要获取服务，需要向网络注册，这个注册过程被称为Attach(以LTE系统为例)。当终端处于无线资源控制(Radio Resource Control，RRC)连接态时，如果当前服务小区的信号质量小于预设值或者终端在CA或DC场景下添加辅小区等情况，服务小区对应的接入网设备会通过一条或多条RRC消息向终端发送测量控制任务，该测量控制任务包括测量配置信息，以指示终端开始进行邻区测量。
测量配置信息中包括待测量小区的频点以及各个频点对应的第一SMTC窗信息。其中，待测量小区可以是服务小区的同频小区或异频小区。其中，同频小区，是指小区用于测量的SSB与服务小区的小区定义SSB具有相同的中心频率和子载波间隔。异频小区，是指小区用于测量的SSB与服务小区的小区定义SSB的中心频率和子载波间隔中至少有一项不同。具体的，异频小区包括第一类异频小区、第二类异频小区和第三类异频小区。第一类异频小区，是指用于测量的SSB与服务小区的小区定义SSB的中心频率不同，但位于服务小区已激活的带宽部分(Bandwidth Part，BWP)内的小区。第二类异频小区，是指用于测量的SSB与服务小区的小区定义SSB的中心频率不同，但位于服务小区已激活的BWP外的小区。第三类异频小区，是指用于测量的SSB与服务小区的小区定义SSB的中心频率相同，但子载波间隔与服务小区不同的小区。其中，上述第一SMTC窗的信息包括第一SMTC窗的长度、周期、偏移量等。例如：第一SMTC的长度可以为1ms、2ms、3ms、4ms、5ms等。第一SMTC的周期可以为5ms、10ms、20ms、40ms、80ms、160ms等。
如图6所示，为待测量小区的类型的示例。小区1为服务小区的同频小区。小区2为第一类异频小区，小区3为第二类异频小区。
若待测量小区包含有异频小区时，测量配置信息中还包括第一测量间隙的信息。具体的，网络会根据终端之前上报的能力信息，确定下发相应的第一测量间隙的信息。若终端支持独立配置FR1和FR2的测量间隙，则网络侧下发FR1的测量间隙以及FR2的测量间隙。若终端不支持独立配置FR1和FR2的测量间隙，则网络侧下发UE级的测量间隙。其中，第一测量间隙包括第一测量间隙的长度、周期、偏移量等。
S502、终端在第一SMTC窗执行邻区测量，在第二SMTC窗内继续执行邻区测量以及服务小区的数据传输，其中，第二SMTC窗位于第一SMTC后，且第二SMTC窗加上第一SMTC窗的时长大于或等于一个SSB周期；或者，终端在第一测量间隙测量 执行邻区测量，在第二测量间隙内继续执行邻区测量以及服务小区的数据传输，其中第二测量间隙位于第一测量间隙后，且第二测量间隙加上第一测量间隙的时长大于或等于一个SSB周期。
示例性的，终端在接收到接入网设备发送的测量配置信息后，根据配置信息中待测量小区的频点，分别确定各个待测量的同频小区对应的第一SMTC窗，和/或，各个待测量的异频小区对应的第一测量间隙。
而后，终端在第一SMTC窗后确定第二SMTC窗，使得第一SMTC窗和第二SMTC窗的总长度大于或等于邻区的一个SSB周期。和/或，在待测量异频小区的频点对应第一测量间隙后确定第二测量间隙，使得第一测量间隙和第二测量间隙的总长度大于或等于邻区的一个SSB周期。例如，邻区的SSB周期为20ms，第一SMTC窗和第二SMTC窗的总长度可为21ms。又例如，邻区的SSB周期为20ms，第一测量间隙和第二测量间隙的总长度为21ms。一些示例中，若待测量的邻区具有不同的SSB周期时，这里第一SMTC窗和第二SMTC窗的总长度可以大于或等于所有待测量邻区的SSB周期中的最大值，和/或，第一测量间隙和第二测量间隙的总长度大于或等于所有待测量邻区的SSB周期中的最大值。
然后，终端在第一SMTC窗和第二SMTC窗执行同频邻区测量，和/或，在第一测量间隙和第二测量间隙中执行异频邻区测量。
在本申请的一些实施例中，终端在第一SMTC窗执行同频邻区测量的过程，具体过程可以参考现有技术，这里不再赘述。终端在第二SMTC窗内继续执行同频邻区测量，且同时进行服务小区的数据传输。可以理解的是，由于同频邻区测量SSB频点在服务小区已激活的BWP内，即在第二SMTC窗内，终端可以同时接收到服务小区和同频邻区的信号(包括服务小区发送的数据以及同频邻区发送的SSB)。由于不同小区具有不同的物理小区标识(Physical Cell Identifier，PCI)，因此终端可以根据接收到的信号中包含的PCI，对服务小区和同频邻区的信号进行分离，分别得到接收到的服务小区的数据，以及测量到的同频邻区的SSB。而后，终端可以基于测量到的同频邻区的SSB执行同频小区测量工作。在第一SMTC窗和第二SMTC窗外，终端不需执行同频邻区测量，而是继续完成服务小区的数据传输。
例如，请参见图2所示，网络侧配置的第一SMTC窗为SMTC1，终端根据SMTC1确定第二SMTC窗为SMTC3。在SMTC1内，终端执行同频小区测量，在SMTC3内，终端继续执行同频小区测量以及进行服务小区的数据传输。可见，由于SMTC1和SMTC3(即SMTC2)覆盖了至少一个邻区的SSB，由此终端在SMTC2内执行同频小区测量，能够测量到全部的同频小区的SSB。
需要说明的是，终端可以在每个第一SMTC窗后都默认确定第二SMTC窗，这样终端可以在第一SMTC窗和第二SMTC窗内检测到全部的同频小区。
可选的，终端也可以在每个第一SMTC窗的周期内，先在第一SMTC窗内执行邻区测量。如果在第一SMTC窗内未测量到同频小区，或者未测量到预设数量的同频小区，或者测量到的同频小区的信号质量不满足预设条件时，再在第一SMTC窗后确定第二SMTC窗，继续执行邻区测量。也就是说，终端在每个第一SMTC窗的周期内，都先根据第一SMTC窗的测量情况，确定是否扩展本周期内的第二SMTC窗。
可选的，终端还可以第一个第一SMTC窗的周期内，先在第一SMTC窗内执行邻区测量。如果在第一SMTC窗内未测量到同频小区，或者未测量到预设数量的同频小区，或者测量到的同频小区的信号质量不满足预设条件时，再在第一SMTC窗后确定第二SMTC窗，继续执行邻区测量。而后，终端在后续的第一SMTC窗的周期内，可直接确定第二SMTC窗，在第一SMTC窗和第二SMTC窗都进行邻区测量。也就是说，终端根据第一个第一SMTC窗内的测量情况，确定本周期内以及后续周期内是否扩展第二SMTC窗。
在另一个示例中，网络侧配置了两个或多个不同周期的第一SMTC窗时，终端可以根据网络侧配置的每个第一SMTC窗确定第二SMTC窗，在第二SMTC窗内执行同频邻区测量以及接收服务小区的数据。在另一个示例中，终端也可以在网络侧配置的多个第一SMTC窗中选择其中一个第一SMTC窗扩展第二SMTC窗，并在第二SMTC窗内执行同频邻区测量以及接收服务小区的数据。例如，假设网络侧配置了第一周期的第一SMTC窗和第二周期的第一SMTC窗。若终端在第一周期的第一SMTC窗内未测量到同频小区，或者未测量到预设数量的同频小区，或者测量到的同频小区的信号质量不满足预设条件时，终端才在第二周期的第一SMTC窗后确定第二SMTC窗，在第二周期的第一SMTC窗和扩展的第二SMTC窗内测量同频小区。本申请实施例对此不做限定。
由此可见，由于第一SMTC窗和第二SMTC窗覆盖了邻区的一个SSB的周期，那么在第一SMTC窗和第二SMTC窗内执行同频邻区测量，可见保证测量到全部同频邻区的SSB，基于全部的同频邻区进行小区选择，从而提升终端的信号质量，保证终端业务的连续性。
在本申请的另一些实施例中，终端在第一测量间隙执行异频邻区测量。终端在第二测量间隙内继续执行异频邻区测量，且同时接收服务小区的数据。其中，终端在第一测量间隙执行异频邻区测量的过程，以及终端在第一测量间隙和第二测量间隙外接收服务小区的数据的过程，可参考现有技术，这里不再赘述。接下来，详细说明终端在第二测量间隙内同时执行异频邻区测量以及服务小区的数据传输的过程。
一些示例中，如果待测量小区包括第一类异频邻区，由于第一类异频邻区用于测量SSB频点位于服务小区已激活的BWP内，即在第二测量间隙内，终端可以同时接收到服务小区和第一类异频邻区的信号(包括服务小区发送的数据以及第一类频邻区发送的SSB)。后续，终端可以根据频率和PCI对接收到的信号进行分离，分别得到接收到的服务小区的数据，以及测量到的第一类异频邻区的SSB。而后，终端可以基于测量到的第一类异频邻区的SSB执行异频小区测量工作。
另一些示例中，如果待测量小区包括第二类异频邻区时，即由于第二类异频邻区用于测量SSB频点位于服务小区已激活的BWP外，则终端可以根据终端的能力采用以下几种不同的方法，实现在第二测量间隙内执行异频邻区测量以及服务小区的数据传输。
方法A、如果终端的射频通路支持同时接收服务小区和待测量的第二类异频邻区的信号时，则终端在第二测量间隙内使用第一射频接收通道接收服务小区的信号，使用第二射频接收通道接收第二类异频邻区的信号。
示例性的，结合图3和图7，假设终端具有4个接收天线(antenna，简写为Ant)，分别为Ant0至Ant3。其中，每个接收天线可以对应两个射频接收通道，例如，Ant0对应射频接收通道0和射频接收通道4，Ant1对应射频接收通道1和射频接收通道5，Ant2对应射频接收通道2和射频接收通道6，Ant3对应射频接收通道3和射频接收通道7。具体的，终端使用射频接收通道0至射频接收通道3接收服务小区的数据。当时间进入第一测量间隙后，终端切换接收频点，使用射频接收通道0至射频接收通道3接收第二类异频邻区的信号，执行邻区测量。当时间进入第二测量间隙后，终端切换接收频点，使用射频接收通道0至射频接收通道3接收服务小区的数据。与此同时，终端使用射频接收通道4至射频接收通道7接收第二类异频邻区的信号，继续执行邻区测量。在第一测量间隙和第二测量间隙之外，终端使用射频接收通道0至射频接收通道3接收服务小区的数据。
需要说明的是，在现有技术中，在第二测量间隙内，终端仅使用射频接收通道0至射频接收通道3接收服务小区的数据，而没有使用射频接收通道4至射频接收通道7接收第二类异频邻区的信号，继续执行邻区测量。
方法B、如果终端的射频通路不支持同时接收服务小区和待测量的第二类异频邻区的信号时，则终端可以在第二测量间隙内，从接收服务小区信号的射频接收通道中借用至少一个射频接收通道用于接收第二类异频邻区的信号，其余射频接收通道继续用于接收服务小区的信号。
在一个具体实现的方式中，结合图3和图8，假设终端具有4个接收天线，分别为Ant0至Ant3，分别对应射频接收通道0至射频接收通道3。具体的，终端使用射频接收通道0至射频接收通道3接收服务小区的数据。当时间进入第一测量间隙后，终端切换接收频点，使用射频接收通道0至射频接收通道3接收第二类异频邻区的信号，执行邻区测量。当时间进入第二测量间隙后，终端使用射频接收通道0至射频接收通道3中任两个(例如射频接收通道2和射频接收通道3)继续接收第二类异频邻区的信号，继续执行邻区测量。与此同时，终端使用射频接收通道0和射频接收通道1接收服务小区的数据。当然，终端也可以仅使用其中一个射频接收通道接收第二类异频邻区的信号，继续执行邻区测量，同时使用其他的射频接收通道接收服务小区的数据，本申请实施例对此不做限定。在第一测量间隙和第二测量间隙之外，终端使用射频接收通道0至射频接收通道3接收服务小区的数据。
需要说明的是，在现有技术中，在第二测量间隙内，终端使用射频接收通道0至射频接收通道3接收服务小区的数据，而本申请实施例中仅使用射频接收通道0至射频接收通道3中任两个或三个接收服务小区的数据，同时使用剩余的一个或两个射频接收通道接收第二类异频邻区的信号，继续执行邻区测量。
在另一个具体实现的方式中，结合图3和图9，假设终端具有4个接收天线，分别为Ant0至Ant3，分别对应射频接收通道0至射频接收通道3。在终端接收到网络侧下发的测量配置信息后，终端可以周期性或非周期性向网络侧上报第一秩(rank)。其中第一秩为min(第二秩，预设秩)。第二秩为终端根据现有技术计算得到的秩，即终端根据信道状态信息确定的秩。也就是说，终端上报的秩为不大于预设秩。其中预设秩小于终端实际具有的射频接收通道的数量，例如2或1。换言之，终端通过上 报不大于预设秩的方法，降低网络侧调用多进多出(multiple-in multiple-out，MIMO)的层数。这样，网络侧发送的数据流的流数小于终端具有的射频接收通道数，那么终端剩余的射频接收通道可用于接收第二类异频小区的信号。一些示例中，在终端接收到网络侧发送的去测量配置指示后，终端可以重新上报第二秩，使得网络侧可以恢复调用MIMO的层数。
例如，终端计算得到的第二秩为4。若按照现有技术，终端将上报第二秩，那么网络侧根据第二秩调用4*4MIMO，即网络侧发送的数据流的流数为4，于是终端需要调用4个射频接收通道(即，射频接收通道0至射频接收通道3)用于接收服务小区的数据。若采用本实施例提供的方法，终端上报第一秩(例如为2)，那么网络侧根据第一秩调用2*2MIMO，即网络侧发送的数据流的流数为2，于是在第二测量间隙内，终端可以调用其中2个射频接收通道(即射频接收通道0至射频接收通道3中任两个)用于接收服务小区的数据，另外2个射频接收通道可用于接收第二类异频邻区的信号，用于测量邻区。或者，终端上报第一秩(例如为1)，那么网络侧根据第一秩调用采用非MIMO，即网络侧发送的数据流的流数为1，于是终端在第二测量间隙内可以调用其中1个射频接收通道(即射频接收通道0至射频接收通道3中任一个)用于接收服务小区的数据。另外3个射频接收通道中任一个或任几个均可用于接收第二类异频邻区的信号，用于测量邻区。
以终端上报的第一秩为min(第二秩，2)为例。那么，在第一测量间隙内，终端切换接收频点，使用四个射频接收通道或者使用任两个射频接收通道接收第二类异频邻区的信号，执行邻区测量。在第二测量间隙内，终端使用射频接收通道0至射频接收通道3中任两个(例如射频接收通道2和射频接收通道3)接收第二类异频邻区的信号，继续执行邻区测量。与此同时，终端使用其余两个射频接收通道(例如射频接收通道0和射频接收通道1)接收服务小区的数据。在第一测量间隙和第二测量间隙之外，终端使用射频接收通道0至射频接收通道3接收服务小区的数据。需要注意的是，在第一测量间隙和第二测量间隙之外，网络侧发送的数据流的流数依然为2。在终端接收到网络侧发送的去测量配置指示后，终端可以重新上报第二秩，使得网络侧调用MIMO的层数。即，网络侧发送的数据流的流数可以恢复为第二秩。
需要说明的是，与终端测量同频小区类似的，终端可以在每个第一测量间隙后都默认确定第二测量间隙，这样终端可以在第一测量间隙和第二测量间隙内检测到全部的异频小区。
可选的，终端也可以在每个第一测量间隙的周期内，先在第一测量间隙内执行邻区测量。如果在第一测量间隙内未测量到异频小区，或者未测量到预设数量的异频小区，或者测量到的异频小区的信号质量不满足预设条件时，再在第一测量间隙后确定第二测量间隙，继续执行邻区测量。也就是说，终端在每个第一测量间隙的周期内，都先根据第一测量间隙的测量情况，确定是否扩展本周期内的第二测量间隙。
可选的，终端还可以第一个第一测量间隙的周期内，先在第一测量间隙内执行邻区测量。如果在第一测量间隙内未测量到异频小区，或者未测量到预设数量的异频小区，或者测量到的异频小区的信号质量不满足预设条件时，再在第一测量间隙后确定第二测量间隙，继续执行邻区测量。而后，终端在后续的第一测量间隙的周期内，可 直接确定第二SMTC窗，在第一测量间隙和第二测量间隙都进行邻区测量。也就是说，终端根据第一个第一测量间隙的测量情况，确定本周期内以及后续周期内是否扩展第二测量间隙。
由此可见，终端通过上报不大于预设秩的第一秩，降低网络侧调度MIMO层数，从而减少终端接收服务小区数据的所需的射频接收通道数，剩余的射频接收通道可用于接收第二类异频邻区的信号。进而，实现终端在第二测量间隙内可以同时接收服务小区的发送的数据和第二类异频小区发送给的SSB。由此终端即可测量到所有的第二类异频邻区，又可避免因减少用于接收服务小区数据的射频接收通道数可能带来的误码，提升终端接收服务小区的数据的正确性。
在又一个具体实现的方式中，结合图3和图10，假设终端具有4个接收天线，分别为Ant0至Ant3，分别对应射频接收通道0至射频接收通道3。在网络侧向终端发送测量配置信息后，网络侧可以修改配置给终端的BWP，以降低终端最大支持的MIMO层数，从而减少终端用于接收服务小区数据的所需的射频接收通道数。也就是说，网络侧发送的终端的BWP配置指示的MIMO层数小于该终端能够支持的最大的MIMO层数。例如，终端能够支持4*4MIMO，而网络侧在发送测量配置信息后，配置终端最大支持2*2MIMO的BWP，那么终端最大需要2个射频接收通道用于接收服务小区发送的数据。在一示例中，在网络侧发送去测量配置指示后，网络侧也可以重新配置终端的BWP，恢复终端支持最大的MIMO层数。
例如，若按照现有技术，网络侧配置终端最大支持4*4MIMO的BWP，那么网络侧发送的数据流的流数为4，于是终端需要调用4个射频接收通道用于接收服务小区的数据。若采用本实施例提供的方法，网络侧配置终端最大支持2*2MIMO的BWP，那么网络侧发送的数据流的流数为2，于是，在第二测量间隙内，终端可以调用其中2个射频接收通道(即，分别对应射频接收通道0至射频接收通道3中任两个)用于接收服务小区的数据，另外2个射频接收通道可用于接收第二类异频邻区的信号，用于测量邻区。
具体的，在第一测量间隙内，终端切换接收频点，使用射频接收通道0至射频接收通道3或者使用射频接收通道0至射频接收通道3中任两个接收第二类异频邻区的信号，执行邻区测量。在第二测量间隙内，终端使用射频接收通道0至射频接收通道3中任两个(例如射频接收通道2和射频接收通道3)接收第二类异频邻区的信号，继续执行邻区测量。与此同时，终端使用其余两个射频接收通道接收服务小区的数据。在第一测量间隙和第二测量间隙之外，终端使用四个射频接收通道或者其中任两个射频接收通道接收服务小区的数据。需要注意的是，网络侧发送的数据流的数目依然为2。在网络侧向终端发送去测量配置指示后，网络侧可以重新配置终端的BWP，恢复终端支持最大的MIMO层数。
由此可见，网络侧通过修改终端的BWP配置，降低终端可支持的最大MIMO的层数，从而减少终端接收服务小区数据的所需的射频接收通道数，剩余的射频接收通道可用于接收第二类异频邻区的信号。进而，实现终端在第二测量间隙内可以同时接收服务小区的发送的数据和第二类异频小区发送的SSB。由此终端即可测量到所有的第二类异频邻区，又可避免因减少用于接收服务小区数据的射频接收通道数量可能带 来的误码，提升终端接收服务小区的数据的正确性。
如果待测量小区包括第三类异频邻区，与同频小区的测量相似。由于第三类异频邻区用于测量SSB频点与服务小区的中心频率相同，即在第二测量间隙内，终端可以同时接收到服务小区和第三类异频邻区的信号(包括服务小区发送的数据以及第一类频邻区发送的SSB)。后续，终端可以根据PCI以及子载波间隔对接收到的信号进行分离，分别得到接收到的服务小区的数据，以及测量到的第三类异频邻区的SSB。而后，终端可以基于测量到的第三类异频邻区的SSB执行异频小区测量工作。
S503、终端向接入网设备发送邻区的测量报告。
其中，测量报告(MR,Measurement Report)是LTE、NR系统等的一项重要功能。物理层上报的测量结果可以用于系统中无线资源控制子层完成诸如小区选择/重选及切换等事件的触发，也可以用于网络邻区维护，SCG添加等功能。在连接态下，网络测量通常有如下几个目的：
1、Pcell的切换，当终端驻留的Pcell的网络质量满足预设条件时，例如当前小区的信号质量低于阈值，即触发A2事件(Event A2),网络分配异频点用于测量邻小区的网络质量。同频邻区测量网络不需要指示，终端可以在连接态下随时测量。
2、Scell的添加，如果测量的小区满足A4事件，即EvenA4，A4事件的触发条件可以理解为当测量小区大于网络配的某个门限时，网络则可以为用户配置Scell，用户可以通过Pcell和Scell小区与核心网进行数据交换。例如，如图1所示，当终端驻留在服务小区时，此时服务小区为Pcell,在采用了CA技术之后，终端还需要去测量邻小区(例如邻区1或者邻区2)的网络参数，当测量的邻小区的网络参数满足网络侧配置的某个门限值，即满足了A4事件的触发条件的时候，网络侧可以根据为终端配置Scell小区，从而实现高带宽的数据传输。
3、通过测量报告来进行网络系统操作维护，异频邻区自动配置等操作。
4、在一些特殊的场景下，例如双连接场景(例如EN-DC，NE-DC)下，终端也需要测量双链接时的目标小区，例如测量NR(5G小区)或者LTE小区。
本申请实施例中对接入网设备接收到邻区的测量报告的后续处理不做限定。
综上可见，终端根据网络侧配置的第一SMTC窗或者第一测量间隙，确定扩展的第二SMTC窗或者第二测量间隙，使得终端进行邻区测量的时长至少覆盖邻区的一个SSB，以便测量到全部的邻区。基于测量到的全部邻区的测量报告，从中确定切换后的服务小区或确定辅小区，有利于保持业务的连续性。
