用于接收信号的波束可以称为接收波束(transmission beam，Tx beam)，空域发送滤波器(spatial domain transmission filter)，空间发送滤波器(spatial transmission filter)，空域发送参数(spatial domain transmission parameter)，空间发送参数(spatial transmission parameter)，空域发送设置(spatial domain transmission setting)，或者空间发送设置(spatial transmission setting)。上行发送波束可以通过空间关系、TCI-state、信道探测信号(sounding reference signal，SRS)资源(表示使用该SRS的发送波束)中任一种来指示。因此，上行发送波束还可以替换为SRS资源。
用于接收信号的波束可以称为接收波束(reception beam，Rx beam)，空域接收滤波器(spatial domain reception filter)，空间接收滤波器(spatial reception filter)，空域接收参数(spatial domain reception parameter)或者空间接收参数(spatial reception parameter)，空域接收设置(spatial domain reception setting)，或者空间接收设置(spatial reception setting)。
在使用低频或中频频段时，可以全向发送信号或者通过一个较宽的角度来发送信号，而在使用高频频段时，得益于高频通信系统较小的载波波长，可以在发送端和接收端布置很多天线阵子构成的天线阵列，发送端以一定波束赋形权值发送信号，使发送信号形成具有空间指向性的波束，同时在接收端用天线阵列以一定波束赋形权值进行接收，可以提高信号在接收端的接收功率，对抗路径损耗。
2、准同位(quasi-co-location，QCL)
同位关系用于表示多个资源之间具有一个或多个相同或者相类似的通信特征，对于具有同位关系的多个资源，可以采用相同或者类似的通信配置。例如，如果两个天线端口具有同位关系，那么一个端口传送一个符号的信道大尺度特性可以从另一个端口传送一个符号的信道大尺度特性推断出来。大尺度特性可以包括：延迟扩展，平均延迟，多普勒扩展，多普勒频移，平均增益，接收参数，终端设备接收波束编号，发射/接收信道相关性，接收到达角，接收机天线的空间相关性，主到达角(angel-of-arrival，AoA)，平均到达角，AoA的扩展等。具体地，所述同位指示用于指示所述至少两组天线端口是否具有同位关系为：所述同位指示用于指示所述至少两组天线端口发送的信道状态信息参考信号是否来自相同的传输点，或所述同位指示用于指示所述至少两组天线端口发送的信道状态信息参考信号是否来自相同的波束组。
3、参考信号(Reference Signal)
根据LTE和/或NR的协议，在物理层，上行通信包括上行物理信道和上行信号的传输。其中上行物理信道包括物理随机接入信道(physical random access channel，PRACH)，上行控制信道(physical uplink control channel，PUCCH)，上行数据信道(physical uplink shared channel，PUSCH)等，上行信号包括信道探测信号(sounding reference signal，SRS)，上行控制信道解调参考信号(PUCCH de-modulation reference signal，PUCCH-DMRS)，上行数据信道解调参考信号PUSCH-DMRS，上行相位噪声跟踪信号(phase noise tracking reference signal，PTRS)，上行定位信号(uplink positioning RS)等等。下行通信包括下行物理信道和下行信号的传输。其中下行物理信道包括广播信道(physical broadcast channel，PBCH)，下行控制信道(physical downlink control channel，PDCCH)，下行数据信道(physical downlink shared channel，PDSCH)等，下行信号包括主同步信号(primary synchronization signal，PSS)/辅同步信号(secondary synchronization signal，SSS)，下行控制信道解调参考信号PDCCH-DMRS，下行数据信道解调参考信号PDSCH-DMRS，相位噪声跟踪信号PTRS，信道状态信息参考信号(channel status information reference signal，CSI-RS)，小区信号(Cell reference signal，CRS)(NR没有)，精同步信号(time/frequency tracking reference signal，TRS)(LTE没有)，LTE和/或NR定位信号(positioning RS)等。
4、传输配置指示(transmission configuration indication，TCI)
协议中高层通过TCI-State来配置QCL，TCI-State的参数用于在一到两个下行参考信号和PDSCH的DMRS之间配置准共址关系，TCI意即Transmission Configuration Indicator，是DCI中用于指示PDSCH天线端口准共址的字段。TCI由RRC配置，在配置信令中称为TCI-state。RRC配置后，由基站发送MAC-CE激活一个或多个TCI状态。基站可以进一步发送DCI指示多个被激活TCI中的一个。TCI包括一个或者两个QCL关系，QCL表征了当前将要接收的信号/信道，与之前已知的某参考信号之间的某种一致性关系。若存在QCL关系，UE可以继承之前接收某参考信号时的接收或发送参数，来接收或发送将要到来的信号/信道。如果TCI状态中包含标识为QCL Type-D的信息，则该TCI可以用于指示波束。QCL Type-A/B/C用于指示时域与频域偏移等信息，不包括空域信息，一般用于辅助终端进行数据接收解 调。
下面介绍TCI状态的配置，激活和指示。
TCI状态配置：网络设备通过RRC信令向终端设备配置多个TCI状态。这些TCI状态均包括一个类型为typeD的QCL-Info。网络设备也可以配置不包括类型为typeD的QCL-info的TCI-state，不过这些TCI状态不是用于数据传输波束的指示，故此处不进一步阐述。
TCI状态激活：网络设备配置多个TCI状态后，还需要通过MAC-CE激活其中8个TCI状态。这8个TCI状态与DCI中的TCI字段的8个值是一一对应的。即，DCI的TCI字段的8个值对应的是哪8个TCI状态，是通过MAC CE来确定的。
TCI状态指示：网络设备通过DCI中的TCI字段来指示一个具体的TCI-state。例如，网络设备发送给终端设备的DCI中的TCI字段的值为000，表示数据传输波束采用的000对应的TCI状态。该TCI状态内的类型为typeD的QCL-Info所包含的参考信号是索引为#1的信道状态信息-参考信号(channel state information–reference signal，CSI-RS)，表示数据传输采用的波束与索引为#1的CSI-RS对应的接收波束是相同的。索引为#1的CSI-RS对应的接收波束可通过波束测量流程来确定，对终端设备来说是已知的。因此，通过TCI字段的具体取值，终端设备就可以确定数据传输波束对应的波束，从而采用相应的波束来发送或接收数据。
5、公共波束：目前每个信道都采用单独的波束指示。每个信道都有自己对应的波束。在本申请中，定义一种公共波束，同时用于上行和/或下行的多个信道。
公共波束：多个信道、多种信道、多个参考信号、和/或、多种参考信号共同采用的同一个波束。信道包括但不限于至少一种：PDCCH、PDSCH、PUCCH、PUSCH、PRACH。参考信号包括但不限于至少一种：SSB、CSI-RS、DMRS、PTRS、TRS、SRS等。
联合(joint)公共波束：同时用于上行和下行的至少一个信道或至少一个参考信号的传输。例如，PDCCH，PDSCH，PUCCH和PUSCH。联合公共波束也可以称为上下行公共波束。
上行公共波束：同时用于上行的多个信道的传输，和/或，同时用于上行的多种信道的传输，和/或，同时用于上行的一个或多个参考信号的传输。例如，PUCCH、PUSCH和SRS。
下行公共波束：同时用于下行的多个信道的传输，和/或，同时用于下行的多种信道的传输，和/或，同时用于下行的一个或多个参考信号的传输。例如PDCCH、PDSCH和CSI-RS。
公共波束的形式：公共波束可以是一种新定义的结构(不同于现有的TCI-state)。例如，公共波束中包括波束指示的相关信息，包括但不限于以下一种或多种：公共波束标识(identifier，ID)，逻辑小区标识(cell ID)，物理小区标识，部分带宽标识，确定波束的参考信号资源，QCL类型，上行功控相关参数(如路损测量参考信号资源，p0，闭环索引(closedLoopIndex)等)，路径损耗参考信号的标识。
公共波束的应用范围：公共波束可以是小区级的，即一个公共公波束用于一个小区内多个信道的传输。公共波束可以是带宽部分(bandwidth part，BWP)级的，用于一个BWP内多个波束的传输。公共波束也可以是跨小区的，即用于多个小区的多个信道的传输。所述多个小区可以是一个频段(band)内的多个小区。所述多个小区也可以是跨频段的多个小区。
在本申请中，除非特别说明，波束可以指公共波束，也可以指下行波束和/或上行波束。波束可以通过TCI state或RS来进行指示。
应理解，在本申请中，网络设备可以向终端设备发送不同的测量配置，从而指示终端根据这些不同的测量配置进行测量得到不同的测量结果。例如，相比于CSI-RS测量，CSI测量的CSI-RS资源拥有更多的端口数(比如测量8port MIMO信道)。
还应理解，在本申请中，网络设备向终端设备发送的测量配置可以关联不同的上报配置。例如，一部分上报配置指示测量并上报RSRP，另一部分上报配置指示测量并上报CQI等。
需要说明的是，本文中TCI-state和TCI状态两个描述方式可以互相替换。
图3示出了当前一种邻区切换方法的流程示意图。当前技术中，终端在切换前可以测量邻区的SSB信号，并上报测量结果。服务小区(serving cell)根据终端上报的测量结果，向邻区(neighbor cell)请求随机接入资源，用于终端在切换后在目标邻区发起随机接入，建立上行同步、获取上行定时。其具体过程可如下所示：
S301，终端向服务小区上报邻区测量结果。
S302，服务小区向邻区发送随机接入资源请求消息。
S303，邻区向服务小区发送随机接入资源响应消息。
S304，服务小区向终端发送邻区随机接入资源。
S305，终端向邻区发送随机接入前导码。
S306，邻区向终端发送随机接入响应消息。
S307，邻区向终端发送RRC重配置消息。
其中，在该RRC重配置消息中包括L1测量资源，该测量资源用于终端进行波束训练。
S308，终端进行L1测量上报。
其中，终端在切换小区后(由服务小区切换至邻区)在邻区上进行L1测量上报的过程即可称为波束训练的过程，该过程可以具体包括如下三个阶段：
阶段1：终端固定接收波束，接收网络设备扫描发送的宽波束，确定信号质量较好(如RSRP最大)的下行宽波束；
阶段2：网络设备在终端质量最佳的宽波束的范围内，使用多个窄波束进行扫描。终端确定质量较好的下行窄波束。
阶段3：网络设备固定下行窄波束发送参考信号，终端使用不同的窄波束进行接收扫描，确定较好的接收波束。
此外，在确定波束后网络设备往往还需要终端在该波束上进行信道测量，获得信道信息。网络设备根据信道信息来确定预编码方案，以此获得多输入多输出(multiple-input multiple-out-put，MIMO)系统的空分复用增益。在协议中体现为邻区向终端指示触发CSI(信道状态信息)测量上报。终端经过一段时间的测量(终端需要测量多端口参考信号，并基于处理和计算得到反馈内容)，再上报测量结果。
S309，邻区根据测量结果指示波束。
S310，终端在邻区上使用确定好的波束与网络设备进行数据通信。
由上可知，在当前技术中，终端在切换小区后，需要在切换后的小区上重新进行波束训练和信道信息获取，可能会导致终端的数据传输中断时间较长，用户体验不佳。
基于此，本申请提出一种传输测量结果的方法和装置，以期望能够减小终端切换到新小区后恢复数据传输的时延，提升用户体验。

可选的，终端设备确定第二RS测量结果，包括：终端设备根据终端设备的能力信息确定第二RS测量结果所关联小区的数量；或者，终端设备根据预配置信息(例如协议规定或者本地配置)确定第二RS测量结果所关联小区的数量。
可选的，第二RS测量结果为至少一个候选邻区RS测量结果中大于第一阈值的一个或多个RS测量结果，第一阈值为预设值；或者，第二RS测量结果为至少一个候选邻区RS测量结果中质量值由大到小顺序排列的前N个RS测量结果，N为正整数。其中，上述第一阈值和N的具体数值可以是第一网络设备通过测量配置信息、切换指示信息或者其他无线资源控制RRC携带的配置信息向终端设备进行配置，或者MAC CE携带的指示信息向终端设备进行指示的。
可选的，终端设备在第二RS测量结果的有效时长内保存第二RS测量结果。其中，第二RS测量结果的有效时长的起始时刻为终端设备的服务小区由第一小区切换为第二小区的时刻，或者终端设备获取到第二RS测量结果的时刻，或者终端设备在第一小区上报第一RS测量结果的时刻。第二RS测量结果的有效时长的终止时刻为得到第二RS测量结果之后的第K个时隙，K为正整数；或者，第二RS测量结果的有效时长的终止时刻为得到第二RS测量结果之后的第L个毫秒，L为正整数；或者，第二RS测量结果的有效时长的终止时刻为重新进行RS测量的时刻。
S440，终端设备接收来自第一网络设备的切换指示信息。
对应的，第一网络设备向终端设备发送切换指示信息。
其中，切换指示信息用于指示终端设备将服务小区由第一小区切换为第二小区。可选的，切换指示信息可以包括第二小区的标识ID或者其他小区的ID，用于终端设备识别第二小区，还用于终端设备根据小区的ID最终确定第一RS测量结果。
S450，终端设备在第一小区上确定第一RS测量结果。
其中，终端设备在第一小区上确定第一RS测量结果可以包括两种方式。作为一种可能的实现方式，在执行了上述步骤S430后，终端设备根据第二RS测量结果和切换指示信息确定第一RS测量结果，第一RS测量结果为第二RS测量结果的子集，也就是说第一RS测量结果包括第二RS测量结果中的部分或者全部；作为另一种可能的实现方式，当不执行上述步骤S430时，终端设备可以根据多个邻区的RS测量结果和切换指示信息确定第一RS测量结果，第一RS测量结果为多个邻区的RS测量结果的子集，也就是说第一RS测量结果包括多个邻区的RS测量结果中的部分或者全部。

需要说明的是，上述以测量结果为RS测量结果为例对本申请的技术方案进行了说明，其中，RS可以包括信道状态信息参考信号CSI-RS。但本领域人员可知，测量结果还可以是SSB。换句话说，基于邻区的SSB的测量结果也可以执行上述方法，在切换服务小区后，无需对当前服务小区即切换前的邻区重新进行测量，可以直接继承切换前邻区波束的SSB测量结果。
根据本申请的技术方案，在终端设备切换服务小区后，无需对当前服务小区即切换前的邻区重新进行测量，直接继承切换前邻区波束的测量结果，有助于减小通信时延，提升用户体验。
图6示出了本申请第二种传输测量结果方法的流程示意图。在本实施例中，通过第一网络设备预配置邻区波束，使得终端设备可以在进行小区切换前对相应的参考信号进行测量，可以提前跟踪目标小区的激活波束。其中，第一网络设备位于第一小区，第二网络设备位于第二小区，终端设备进行小区切换前的服务小区(也称为当前的服务小区)为第一小区，终端设备进行小区切换后的服务小区为第二小区。终端设备可以是图1中所示的终端设备102、终端设备103或者终端设备104中的任意一个，第一网络设备可以是图1中所示的网络设备101，第二网络设备可以是图1中未示出的网络设备，例如网络设备106等等。

对应的，第一网络设备接收来自终端设备的至少一个候选邻区的RS测量结果。
其中，终端设备向第一网络设备发送至少一个候选邻区的RS测量结果之前，可以根据至少一个候选邻区的RS测量配置信息在当前的服务小区(第一小区)上进行测量得到候选邻区的RS测量结果，其具体过程可参照图4中步骤S420，在此不再赘述。
S630，终端设备接收来自第一网络设备的第一RS测量结果与第一波束的关联关系。
对应的，第一网络设备确定并向终端设备发送第一RS测量结果与第一波束的关联关系。
其中，第一波束可以是一个或多个波束。第一网络设备可以对多个RS测量结果进行筛选得到第一RS测量结果，并将第一RS测量结果与将来终端设备进行切换后的小区的波束相关联，第一RS测量结果为多个RS测量结果的部分或全部，例如，第一RS测量结果所关联的小区可以是服务质量较好的一个或多个小区，或者，第一RS测量结果所关联的小区可以是服务质量大于一定阈值的小区。
可选的，第一波束可以是传输配置指示TCI或者同步信号块SSB，或者RS。其中，当不改变终端设备的能力要求时，第一网络设备可将现有可激活最大的8个TCI中的N个用于激活邻区的波束TCI，每个TCI对应一个邻区或者多个TCI对应一个邻区，可选的，邻区的波束可以为潜在邻区的TRS接收波束。或者，第一网络设备可以为终端设备单独配置预激活的TCI列表(TCI state list)，用于跟踪邻区的TRS波束；或者，第一网络设备可以根据终端设备已测量并上报的邻区TCI进行筛选，从而确定为终端设备配置特定的TCI。
可选的，第一网络设备向终端设备发送的还可以是指示信息，该指示信息用于指示终端设备在进行小区切换后的激活波束。
可选的，第一网络设备还可以不向终端设备发送关联关系或者指示信息，直接为终端设备激活其进行小区切换后的激活波束。换句话说，第一网络设备向终端设备直接发送邻区的TCI状态配置信息。例 如，第一网络设备根据从终端设备接收到的测量结果，向终端设备发送激活信令，用于激活终端设备在第一小区(进行小区切换前的小区)通信时激活的第二小区(进行小区切换后的小区)的波束或者TCI状态。其中，该激活信令可以包括激活波束的目标小区的标识以及激活TCI的标识，激活TCI的标识为目标小区配置的TCI状态的标识。

S640，终端设备接收来自第一网络设备的切换指示信息。
对应的，第一网络设备向终端设备发送切换指示信息。
其中，切换指示信息可以包括第一波束。
其中，该步骤的具体过程可参照图4中步骤440，在此不再赘述。
S650，终端设备根据关联关系确定第一波束为终端设备在第一小区激活的第二小区的波束。
S660，终端设备将服务小区由第一小区切换为第二小区，将第一波束确定为激活波束。
其中，在进行小区切换后，终端设备将第一波束确定为激活波束也可以解释为：终端设备将原有激活TCI state list删除，替换成预激活的第一波束(或者TCI)。可选的，第一波束包括上述切换指示信息所指示的波束，切换指示的波束可以作为统一TCI(unified TCI)。当切换指示信息所指示的波束作为激活波束后，该波束可能激活并映射到最小的代码点000，或者，直接作为切换后新小区通信的公共波束。当第一波束包括多个测量过的波束时，则默认激活多个波束，其代码点(codepoint)映射可按照L1上报的顺序，或者按照切换指示信息中指示的顺序。
可选的，激活波束包括以下至少一种：激活的TCI状态所关联代码点；终端设备在接收到波束指示激活波束特定时长后，能够基于指示的波束接收或发送数据；或者，终端设备在测量上报中包括TCI状态关联的参考信号的测量结果。
将第一波束确定为激活波束具体可以包括为第一波束关联代码点。例如第一波束关联代码点“000”，第二网络设备在第二小区可以进一步发送DCI(下行控制信息)信令，用于指示波束的比特域取值“000”，即表示将终端的接收或发送波束确定为第一波束，终端在波束指示生效后，即可基于第一波束接收下行信号或信道，或者基于第一波束发送上行信号或信道。
如图7所示，示例性的，在该实施例中，终端设备在第一小区进行测量获得的邻区RS测量结果中可以包括参考信号关联物理小区标识为PCI#1以及PCI#2的测量结果，其中，作为一种可能的实现方式，终端设备可以关联PCI#1的预激活的TCI状态上报至第一网络设备，从而第一网络设备可以获知终端设备将PCI#1小区关联的TCI状态激活，其中包括TCI 6。作为另一种可能的实现方式，终端设备可以将关联了PCI#1的一个或多个测量结果上报给第一小区，其中包括第一RS测量结果。终端设备可以根据预配置信息，确定上报了测量结果的一个或多个参考信号所关联的TCI状态，该TCI状态为第二小区的TCI状态。终端设备根据上报的测量结果，确定关联的至少一个TCI状态为激活的TCI状态。同时，服务小区(内的网络设备)根据发送给终端设备的预配置信息所包括的参考信号与邻区TCI状态的关联关系，以及终端设备上报的邻区的参考信号的测量结果，确定终端设备当前激活的邻区TCI状态，其中包括TCI 6。
终端设备还可以确定激活的邻区TCI状态对应的代码点。其中，一种可能的方法是根据上报的邻区的参考信号的测量结果，由测量结果的参考信号质量大到小的将参考信号对应的TCI状态由小到大映射到代码点。上述方法还可以包括，终端设备将切换指示信息中所指示的TCI状态映射到代码点最小的一个。例如服务小区(内的网络设备)通过切换命令向终端设备指示TCI 6，则终端设备将TCI 6关联到代码点000，其他代码点由小到大关联测量结果由大到小的参考信号所对应TCI状态。这样，终端设备在进行小区切换后，在新小区下可以TCI 6所指示的波束进行通信。节省了在切换后，新小区重新配置、激活TCI状态所需要的时延。
S670，终端设备在第二小区上通过第一波束与第二网络设备进行数据通信。
对应的，第二网络设备在第二小区上通过第一波束与终端设备进行数据通信。
根据本申请的技术方案，通过预配置邻区波束，使得终端设备可以在进行小区切换前对相应的参考信号进行测量，可以提前跟踪目标小区的激活波束，切换小区后，降低波束指示的时延。

S810，终端设备接收来自第一网络设备的测量配置信息。
