Description

波束测量方法和装置 技术领域
本申请涉及通信领域，并且更具体地，涉及一种波束测量的方法和装置。
背景技术
在NR(new radio)系统中，终端设备与网络设备可以通过波束对准实现数据传输。为了提升信号的覆盖能力，网络设备需要使用波束成型技术来发送下行信号。从网络设备的波束成型方式来看，波束分为两种，一种为模拟波束，通过在模拟域上调整模拟权值形成不同的波束；另一种为数字波束，通过在数字域上调整数字权值形成不同波束。
一些低频系统中，数字波束的数量可能远远大于模拟波束的数量，波束测量过程中，终端设备需要向网络设备反馈波束的索引。由于在接收信号时，数字域可以重新确认权值，网络设备只需要知道模拟波束的索引，并不需要知道数字波束的索引。因此，按照现有反馈机制需要上报数字波束的索引，由于数字波束数量较多，占用的比特较多，因此现有反馈机制上报了冗余信息，上报效率低。
发明内容
本申请提供一种波束测量的方法和装置，通过对多个资源进行合并测量，减小反馈开销。
一方面，公开了一种波束测量的方法，包括：终端设备接收网络设备发送测量配置信息，所述测量配置信息包括多个资源集合的配置信息，每个资源集合包括一个或多个资源；对每个资源集合中的资源进行合并测量，并根据测量结果选择一个或多个的资源集合上报给所述网络设备。
相应的，网络设备向所述终端设备发送所述测量配置信息，并且接收终端设备上报的所述一个或多个资源集合。
选择上报的一个或多个资源集合可以为测量结果符合质量要求的资源集合，例如：测量结果最好的资源集合，或者测量结果大于或等于设定门限值的资源集合；可以上报所述一个或多个的资源集合的索引。
结合上述方案，终端设备通过一个接收波束，或者多个同时产生的接收波束对每个资源集合中的资源进行合并测量。
上述资源为参考信号资源，可以为下行参考信号资源，也可以为上行参考信号资源；例如：CSI-RS(channel state information-reference signal，信道状态信息参考信号)资源，SRS(sounding reference signal，信道探测参考信号)资源；资源集合也可以称为资源组。
另外，上述多个资源集合中，至少有一个资源集合包括多个资源，或者每个资源集合均包括多个资源；多个为2个或2个以上。
结合上述方法，所述资源配置信息中的每个资源集合对应一个资源分类信息，用于 指示该资源集合是否用于合并测量或是否能用于合并测量。终端设备可以对指示合并测量的资源集合进行合并测量。例如，将配置了Combination On＝a的资源集合中的多个资源进行合并测量，a也可以为其他值；如果某个集合没有配置Combination On或配置了Combination Off，则该资源集合不能进行合并测量。
另外一个方案中，也可以默认同一集合或分组内的资源用于合并测量，不同的集合或分组内的资源不能用于合并测量。
在另一个方案中，测量配置信息也可以包括多个资源的配置信息，每个资源对应一个资源分类信息，终端设备将具有相同资源分类信息的多个资源进行合并测量，并上报多个资源的共同索引，可以用其中一个资源的索引作为该共同索引。例如：将配置了Combination On＝a的多个资源合并测量，测量结果为A；将配置了Combination On＝b的多个资源合并测量；测量结果为B；如果A优于B，则上报Combination On＝a的多个资源的共同索引，可以用所述多个资源中一个资源的索引作为共同索引。
上述资源分类信息也可以称为合并测量标识。
另一个例子中，也可以将配置了Combination On＝a的资源集合与配置了Combination On＝a的一个或多个资源进行合并测量，将配置了Combination On＝b的资源集合与配置了Combination On＝b的一个或多个资源进行合并测量，并上报测量结果较好的资源集合与一个或多个资源的共同索引，可以用集合索引，也可以用其中一个资源的索引作为共同索引。
进一步的，还可以上报资源分类信息对应的标识来表示相应的进行合并测量的资源的共同索引；例如：通过上报与Combination On＝a对应的标识来表示Combination On＝a的多个资源，通过上报与Combination On＝b对应的标识来表示Combination On＝b的多个资源；例如：比特0表示Combination On＝a的多个资源，比特1表示Combination On＝b的多个资源。
进一步的，所述测量配置信息中还可以包括用于指示某个资源和/或资源集合能用于合并测量的指示信息，可以包含在该资源和/或资源集合的资源配置信息中，也可以由网络设备单独下发；这种情况下，如果终端设备检测到测量配置信息中包含合并测量指示，或者接收到网络设备下发的合并测量指示，则终端启动合并测量，否则不启动合并测量。
例如，所述测量配置信息中还包括合并测量指示，例如：CombinationOn＝1，用于指示终端设备启动合并测量；终端设备检测到合并测量指示，然后启动合并测量；如果没有检测到该合并测量指示，则不启动合并测量。
所述合并测量指示还可以包含在测量配置信息中的上报配置中，也可以由网络设备单独下发给终端设备，例如：通过RRC(radio resource control，无线资源控制)，MAC-CE(Media Access Control control element，MAC控制元素)或DCI(downlink control information，下行控制信息)等下发合并测量指示给终端设备。
若网络设备单独下发合并测量指示给终端设备，则结合上述方法，终端设备进行合并测量之前，进一步包括：接收网络设备下发的指示信息，所述指示信息用于指示终端设备启动合并测量；指示信息可以为RRC、MAC-CE或DCI等。
结合上述方法，终端设备还可以向网络设备上报选择的所述一个或多个的资源集合的合并测量结果；所述合并测量结果中可以包括所述一个或多个的资源集合中有效测量 资源的信息。
结合上述方法，所述测量配置信息还包括各个资源集合分别对应的波束信息，例如：每个资源集合的资源配置信息还包括该资源集合对应的波束信息。
进一步的，上述测量配置信息还可以包含以下一项或多项：合并测量生效的起始时间、合并测量的测量量(如参考信号接收质量、信号与干扰噪声比、参考信号接收功率等)、反馈量等。
结合上述方法，所述合并测量，可以将各个资源分别测量，将各个测量结果取平均值，也可以将各个测量结果中的部分取平均值，如取前N个较好的测量结果取平均值，N也可以由网络设备配置，也可以由终端设备自己确定，或者协议预先约定。
结合上述方法，网络设备可以将终端设备上报的一个或多个的资源集合用于波束指示，例如：网络设备向终端设备下发的波束配置信息，所述波束配置信息包括所述一个或多个的资源集合与上行信道(或信号)或下行信道(或信号)的关联关系。所述终端设备可以使用所述一个或多个的资源集合对应的接收波束接收被关联的信道或信号，或者，所述终端设备可以使用所述一个或多个的资源集合对应的接收波束关联的发送波束发送被关联的信道或信号。
结合上述方法，所述终端设备使用波束测量时的接收波束(一个或多个同时产生的接收波束)接收网络设备下发的与所述一个或多个的资源集合关联的下行信道，或使用波束测量时的接收波束对应的一个或多个发送波束向所述网络设备发送所述一个或多个的资源集合关联的上行信道。
上述波束测量的方法，由于对资源集合中的资源进行合并测量，并根据测量结果上报资源集合，减小了反馈开销。

上述图1给出了本申请涉及的一种网络系统架构，本申请适用于如图1所示的基于波束的多载波通信系统，例如5G新空口NR。该系统中包括通信系统中的上行(终端设备到网络设备)和下行(接入网络设备到终端设备)通信。根据长期演进LTE/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随机接入信道(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)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，简称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)等。
在NR中，下行信道所使用的波束或参考信号发送对应的波束的波束指示是通过关联传输配置指示(transmission configuration indicator，TCI)状态表中的参考资源索引实现的。
具体而言，基站通过无线资源控制(radio resource control，RRC)高层信令配置了一个TCI状态表(对应38.331中的TCI-states)，每个TCI状态表包含若干个TCI状态(对应38.331中TCI-RS-Set)。每个TCI状态包括TCI状态ID(TCI-RS-SetID)、一种或两 种准同位(quasi-co-location，QCL)类型指示(QCL-type A/B/C/D)以及各个类型指示对应的参考RS-ID。QCL类型包含了以下几种：
QCL-Type A:{多普勒频移,多普勒扩展,平均时延,时延扩展}
QCL-Type B:{多普勒频移,多普勒扩展}
QCL-Type C:{平均时延,多普勒频移}
QCL-Type D:{空间接收参数}
其中，QCL-type D表示空间准同位。当需要指示接收波束时，基站通过高层信令或控制信息指示其中的一个包含空间准同位信息的TCI状态，UE根据该TCI状态读取QCL-type D对应的参考RS-ID，然后UE可以根据当前维护的与RS-ID相对应的空间接收配置(接收波束)进行接收。根据38.214，如果一个TCI状态中含有空间准同位指示(QCL-type D)，那么该空间准同位指示的对应参考RS可能是一个SS/PBCH Block或是一个周期或半持续的CSI-RS。不同的下行信道的波束指示(TCI指示)在不同位置完成：
PDCCH的波束指示由RRC配置的高层信令tci-StatesPDCCH与一个或多个TCI状态关联，当关联的TCI状态数大于1时，由MAC-CE高层信令选择其中一个。
PDSCH的波束指示由PDCCH传输的DCI中的TCI字段关联的状态进行指示。NR标准中DCI中包含的TCI字段的长度为3bit(对应8个TCI状态)，当RRC信令包含的TCI状态数量M小于8时，激活的TCI状态直接映射到TCI字段中，否则由高层信令指示最多8种参与映射的TCI状态。当高层信令提示TCI字段未在DCI中出现时，UE重用控制信道的波束指示进行数据信道接收。
对于上行传输，NR尚未定义空间准同位关系，上行的波束指示直接通过参考信号资源标识实现：
PUCCH的波束指示通过RRC参数PUCCH-Spatial-relation-info指示，该参数可能包括了一个或者多个参考信号资源标识，当包含多个参考信号资源标识时，由MAC-CE高层信令选择其中一个。PUCCH的波束指示内容可能是上行或下行的参考信号资源标识，包括SSB Index，CRI或者SRS Index，表示建议UE使用接收/发送该下行/上行参考信号资源的对应波束进行上行传输。
PUSCH的波束信息通过DCI中的SRS Index进行配置。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。
空域准同位(spatial QCL)：spatial QCL可以认为是QCL的一种类型。对于spatial有 两个角度可以理解：从发送端或者从接收端。从发送端来看，如果说两个天线端口是空域准同位的，那么是指这两个天线端口的对应的波束方向在空间上是一致的。从接收端来看，如果说两个天线端口是空域准同位的，那么是指接收端能够在相同的波束方向上接收到这两个天线端口发送的信号。
图2中描述了一种典型的发射机架构。其中，数字权值在数字域进行调整，而模拟权值在模拟域通过移相器进行调整。
因此，基站通常同时有数字波束权值和模拟波束权值，数字波束和模拟波束并非互斥关系。例如，在图2的基站架构中，基站可以先在数字域上对信号进行数字加权形成数字波束，再在模拟域上进行模拟加权形成模拟波束。此时，基站发射出去的信号其实是同时包含了数字波束和模拟波束的加权效果。
在高频系统中，由于数字权值增加实现带来功耗和成本大量增加，因此高频系统可能倾向使用较小数量的数字权值和较大数量的模拟权值。对于一些低频段系统，由于数字通道的功耗和成本相对可承受，可能会使用较多数量的数字权值甚至使用只有数字权值的基站架构(即全数字波束成型架构，Digital beamforming,DBF)。
进行波束测量时，终端设备并不对模拟波束和数字波束进行区分，终端对一组参考信号资源进行测量，并反馈测量结果符合质量要求的参考信号资源，至于基站实际使用数字波束或模拟波束，还是使用数字波束加模拟波束发送该参考信号资源，终端设备并无感知，如图3所示，终端设备只能区分一个资源，无法区分该资源由数字波束发送还是由模拟波束发送。
高频系统通常拥有较大数量的模拟权值，和较小数量的数字权值，因此高频系统中的波束管理为通过波束扫描确定一个模拟波束。
对于一些使用了模拟波束+数字权值架构的低频系统，数字波束的数量可能远远大于模拟波束的数量。以图3的示意图举例，图3中基站侧有5个数字波束，分别属于2个不同模拟波束，终端设备识别的是一个数字和模拟波束的合并信号，例如(数字波束1+模拟波束1)，不同的数字和模拟波束组合只能通过基站配置不同的参考信号资源区分，终端侧是无法感知的，如表1所示：
Figure PCTCN2021091617-appb-000001
表1：资源和数字模拟波束对应关系
终端设备可以对上述5个资源分别测量，并向基站反馈其中信号质量最好的资源编号(例如资源3)，基站便可以知道使用数字波束3和模拟波束1合并接收终端发送的信号。然而，由于在信号接收过程中数字域可以重新确认权值，因此在接收信号时，基站只需要知道应该使用哪个一个模拟波束(即模拟波束1)来进行接收，并不需要知道数字波束索引，按照现有反馈机制上报了冗余信息，上报效率低。
如果基站不使用数字波束，只是用模拟波束发送不同资源，这样终端设备上报的索引就是模拟波束索引，没有冗余信息。但是，低频系统的模拟波束数量很少，波束很宽，如果不使用数字波束集中能量发送，终端设备可能无法收到信号。
本申请提出一种波束测量的方法，通过对多个资源进行合并测量，减小反馈开销，提高测量上报效率。
图4示出了根据本申请实施例的波束测量的方法200的示意性流程图。该方法包括：
101:基站给终端下发测量配置信息；包括：测量资源配置信息，测量上报配置信息等。
所述测量资源配置信息包括多个用于合并测量的资源集合，每个资源集合包括一个或多个资源；本申请中，资源集合也可以称为资源组，本申请实施例以资源为参考信号资源为例进行说明，例如CSI-RS资源。
一个例子中，每个资源集合都包括多个资源；或者，部分资源集合包括多个资源，部分资源集合仅包括一个资源，仅包括一个资源的集合看成单个资源即可；多个为2个或2个以上。
例如：基站为终端分配了7个资源，资源1、2、3为资源集合1，资源4、5为资源集合2，资源7为资源集合3，三个资源集合均用于合并测量。包括资源集合3可以看成单个资源，可以对该单个资源进行测量。
可选的，每个资源集合对应一个模拟波束，一个集合内的每个资源对应一个数字波束。例如，参考图3，资源集合1对应模拟波束1，资源1、2、3分别对应的数字波束1、2、3；资源集合2对应模拟波束2，资源4、5分别对应的数字波束4、5。
一个例子中，测量资源配置信息可以包括资源分类信息，用于指示哪些资源和/或资源集合能进行合并测量，例如：资源分类信息用于指示不同的资源类型，包括可合并的资源(或资源集合)和不可合并的资源(或资源集合)。终端可以将可合并的多个资源和/或资源集合进行合并测量，并得到一个测量结果。
例如：基站为终端分配了5个资源，其中资源1、2、3的类型为可合并的资源，资源4、5的类型为不可合并的资源，终端可以将资源1、2、3进行合并测量。
上面例子中，基站为终端分配了7个资源，如果资源集合1的类型为可合并资源集合，资源集合3(即资源7)为可合并资源，则终端可以将资源1、2、3、7进行合并测量。
另一个例子中，基站也可以通过配置分组的方式指示哪些资源进行合并测量。例如，同一个分组内的资源可以合并测量，不同分组的资源不能合并测量；或者默认同一个分组内的资源可以合并测量，不同分组的资源不能合并测量。
以下举例进行说明：
资源分类信息可以指示多个资源和/或资源集合是否能合并，并指示哪些资源和/或资源集合之间可以合并。例如：
将包含了参数{Combination On＝a}的资源和/或资源集合用于合并测量，例如：CSI-RS#1的配置信息中包含{Combination On＝a}，则表示CSI-RS#1可以与所有配置了{Combination On＝a}的资源和/或资源集合合并测量；a也可以用其他参数替换，例如：将包含了参数{Combination On＝b}的资源和/或资源集合用于合并测量。
例如：基站为终端分配了5个资源，其中资源1,2,3的参数{Combination On＝a}，资源4,5的参数{Combination On＝b}，则将资源1,2,3进行合并测量，将资源4,5进行合并测量。
如果某个资源或资源集合未配置{Combination On}或配置了{Combination Off},则表示该资源或资源集合不能用于合并测量。
又一个例子中，基站可以将可合并的资源集合和/或资源配置为一个新的集合或分组，并通知终端(或通过协议约定)该集合或分组中的资源是可合并测量的。可以通过设置合并测量标识指示终端该集合或分组中的资源是可合并测量的；也可以单独下发通知消息进行通知。
一种可能的方案如下：
基站配置资源集合{CSI-RS#1,CSI-RS#2…}，并通过协议约定或下发消息指示该集合内的资源可合并测量，例如：基站通过RRC配置该集合的合并测量标识(CombinationOn＝1),表示该资源集合中的资源可以进行合并测量，也可以通过其他消息进行配置，如DCI，MAC-CE等。
另一实施例中，基站也可以将用于合并测量的多个资源配置为一个多端口的测量资源，如：多端口的参考信号资源；则该参考信号资源的各个端口应使用合并测量的方式进行测量。
基站可以配置多个多端口的参考信号资源，每个资源包括多个可合并测量的端口。
进一步的，测量配置信息中还可以包括合并测量指示，该合并测量指示可以包含在测量上报配置信息中。例如：在测量上报量配置中包含合并测量指示；当终端检测到合并测量指示后，才进行合并测量。可以用1bit来指示，1表示开启合并测量，0表示不开启。或者可以通过是否包含合并测量指示表示是否开启测量指示。例如，包含合并测量指示表示开启合并测量，不包含合并测量指示表示不开启合并测量。当终端检测到测量上报配置信息中包含了合并测量指示，则终端对合并测量标识指示的资源和/或资源集合进行合并测量。
进一步的，上述测量配置信息还可以包含以下一项或多项：合并测量生效的起始时间、参与合并测量的资源和/或资源分组(包括哪些分组可以合并)、合并测量的测量量、反馈量等。
另外，基站也单独可以下发指示信息指示终端启动合并测量。该指示信息可以是一个RRC消息，也可以是一个MAC-CE，也可以是DCI。
例如：基站可以使用一个特殊DCI格式，用于指示终端开启合并测量，当终端检测到该特殊DCI格式时，启动合并测量，例如：
如果基站针对可合并的资源和/或资源集合配置了合并测量标识(例如：CombinationOn＝1)，当终端检测到指示合并测量开启的DCI格式时，终端对合并测量标识指示的资源和/或资源集合进行合并测量。
可选的，基站也可以使用MAC-CE指示终端进行合并测量，例如：
终端接收到指示终端进行合并测量的MAC-CE后，进入合并测量模式，与上述DCI例子类似，终端对合并测量标识指示的资源和/或资源集合进行合并测量。
进一步的，MAC-CE指示终端进行合并测量，还可以进一步指示哪些资源进行合并 测量。指示方式可以通过二进制字符串和资源集合一一映射的方式进行指示，例如，比特字符串中的第1个比特为与第1个资源集合(或ID为0的资源集合)对应。当该位置的比特值为1时，表示该集合应使用合并测量的方式进行测量。
另一个实施例中，如果基站配置了多端口的参考信号资源，当终端未进入合并测量时，可以仅对前两个或前一个端口进行测量，并上报测量结果。当终端进入合并测量模式时(例如接收到上述指示合并测量的指示信息后)，终端对多个端口进行合并测量。
另外，另一些实施例中，基站可以通过隐式方式触发终端进入合并测量，例如：通过一些特别的信令组合指示终端进行合并测量，以下举例进行说明。
例如，当基站配置终端对多个参考信号资源集合进行测量上报(例如上报量为RSRP)，且每个参考信号资源集合中包括配置指示repetition On，此时终端应使用合并测量的方式，上报该集合的RSRP和集合索引，而非某个集合中的资源索引。
例如，当基站配置终端对多个参考信号资源集合进行测量上报(例如上报量为RSRP)，且每个参考信号资源集合中的参考信号的波束指示(例如：空间准同位)为同一个参考信号时(和/或集合自身配置了波束指示时)，终端应使用合并测量的方式，上报资源集合的RSRP和/或资源集合索引，而非某个集合中的资源索引。
例如，当基站配置终端测量N>1个参考信号资源集合进行测量上报(例如上报量为RSRP)，终端应使用合并测量的方式，上报资源集合的RSRP和/或资源集合索引，而非某个集合中的资源索引。
进一步的，对于合并测量的参考信号资源，可以单独配置各个资源接收和/或发送波束信息，也可以为参与合并测量的参考信号资源配置一个公共的接收和/或发送波束信息。可选的，对于参与合并的测量的资源或资源集合，可以只为其中一个资源或资源集合配置接收和/或发送波束信息，终端应假设参与合并测量的资源都是用与该资源或资源集合相同的接收和/或发送波束进行传输。
可选的，对于各个资源独立配置的情况，基站没有为参与合并测量的参考信号资源配置一个公共的接收和/或发送波束信息，当基站通过信令或配置方式激活了合并测量时，终端进入合并测量模式，则应假设参与合并测量的资源使用相同的接收和/或发送波束。如果基站为这些资源配置的波束不同，则终端应假设参与合并测量的参考信号资源使用以下波束发送：
资源ID或资源集合ID最大或最小的
当前的下行控制信道波束
当前下行数据信道波束
初始接入的SSB(synchronization signal block，同步信号块)对应的发送波束，或
最低控制资源集合(Control resource set)ID对应的波束
另外，基站也可以在激活合并测量时，为一个或多个资源或资源集合指示对应的发送和/或接收波束。例如，可以通过前述RRC，MAC-CE或DCI进行指示。
波束的指示方式可以通过参考信号进行指示。例如，可以通过CSI-RS对波束进行指示，该CSI-RS可以用于指示基站发送CSI-RS时的发送波束(或其对应的接收波束)，和/或终端接收该CSI-RS使用的接收波束(或其对应的发送波束)。类似的，可以还可 以通过SRS进行波束指示，该SRS可以用指示终端发送该SRS时的发送波束(或其对应的接收波束)，或基站接收该SRS时的接收波束(或其对应的发送波束)。
测量配置信息还可以包括上报量。
进一步的，基站可以配置合并测量专用的上报量(或称为测量量)，也可以配置普通的上报量。
可选的，基站可以配置RSRP，RSSI，RSRQ，SINR等信息，并通知终端这些测量量需要使用合并测量的方式进行测量。
基站也可以定义新的合并测量量，例如{RSRP，RSSI，RSRQ或SINR}-SET,该测量量表示终端应使用合并测量的方式测量一个资源集合的RSRP，RSSI，RSRQ或SINR。测量量的定义可以沿用3GPP 38.215的方式，区别在于终端可以使用资源集合内任意一个资源的测量量作为该资源集合的测量量，或将资源集合内各个资源视为一个资源进行整体的测量并上报。
可选的，测量配置信息中可以包含一个上报量的测量方式。例如，基站配置的测量上报配置信息包含：
{测量资源、上报量、上报使用的信道资源、上报周期、上报量的测量方式….}，其中上报量测量方式可以指示该上报量使用合并测量还是非合并测量的方式。测量资源中包含了用于合并测量的资源或资源集合的索引信息。
可选的，基站也可以配置一个普通的上报量，通过触发或指示的方式激活合并测量方式。例如，当基站为终端配置了上报量为RSRP，并且通过触发方式开启了合并测量时，则终端使用合并测量方式对上报量进行合并测量。例如：可以通过RRC，MAC-CE，DCI等指示终端进行合并测量。
可选的，基站可以为终端配置一个合并测量的资源集合索引，可以包含在测量上报配置中，例如，上报量配置为特殊的合并测量的资源集合索引，例如CSI-RS resource set index(CRSI)，当终端接收到的测量配置信息中包含该上报量时，则启动合并测量。
102：终端根据测量配置信息，对多个资源集合分别进行合并测量。
所述合并测量，可以通过终端的一个接收波束，或者多个同时产生的接收波束进行。
例如：测量资源配置信息包括3个用于合并测量的资源集合，并且配置的测量量为RSRP，则分别对3个资源集合中的资源进行合并测量，得到3个RSRP的测量结果，并根据测量结果选择其中一个或多个资源集合上报，可以上报资源集合的索引或编号；例如：将测量结果最好资源集合的索引上报给基站；进一步的可以将相应的测量结果也上报。或者将测量结果高于预设门限的一个或多个资源集合上报。
由于使用了合并测量，并且上报了资源集合的索引，因此减小了反馈开销。
另一个例子中，当基站指示终端进行合并测量时，即终端接收到基站下发的合并测量指示时，终端应将用于合并测量的资源和/或资源集合的进行合并测量。
例如，一个参考信号的资源的集合中包含了4个参考信号资源：{CSI-RS#1,CSI-RS#2,CSI-RS#3,CSI-RS#4},当基站指示终端对该集合的RSRP进行合并测量时，终端应将CSI-RS#1,CSI-RS#2,CSI-RS#3 CSI-RS#4四个资源的视为一个等效资源进行测量，例如：将4个资源的RE(resource element，资源单元)结合作为一个整体RE进行RSRP测量， 即对该等效资源的进行测量，如图5左侧A所示。
如果基站为终端配置的资源为多个多端口的参考信号资源，终端将多个端口的资源当成一个资源进行合并测量，如图5右侧B所示。
另一个例子中，合并测量的方式如下：
分别测量资源集合中各个资源的RSRP，将资源集合中的多个资源的RSRP相加后取平均值。也可以由终端选择集合中一个或多个资源，分别测量RSRP后，将结果相加取平均值，或将测量结果最大的N个资源的RSRP相加取平均值等。N可以通过协议约定，或基站为终端配置，或由终端自己确定。
在另一个实施例中，基站可以为终端配置一个多端口的资源，并通知终端进行合并测量。
例如，基站为终端配置一个N>1或N>2个端口的资源，当合并测量生效时(生效条件可以参考上述实施例)，终端应将N个端口的资源进行合并测量，如选择其中一个或多个端口，测量RSRP后进行相加取平均值，或选择最大的N个端口的RSRP相加取平均等。N可以通过协议约定，或基站为终端配置，或终端自行确定。当合并测量未生效时，终端仅测量前两个或第一个端口；其中，具体测量一个端口(例如：端口1)还是两个端口(端口1和端口2)可以通过基站配置，或通过协议约定，例如：通过协议约定默认测量前两个端口。
103：终端根据测量结果，选择一个或多个资源集合上报
例如，基站配置了两个资源集合：
CSI-RS resource set #1{CSI-RS resource#1,CSI-RS resource#2}
CSI-RS resource set #2{CSI-RS resource#3,CSI-RS resource#4}
终端可以根据合并测量结果从两个资源集合中选择一个测量结果较好的上报，上报内容包括所选资源集合的索引和/或测量结果。
例如，终端对资源集合1和资源集合2分别测量RSRP，并确定上报的资源集合。如资源集合1的RSRP测量结果优于资源集合2，此时终端通过上行信道(例如PUSCH或PUCCH)反馈该资源集合2的索引，进一步的，还可以上报该资源集合2的测量结果。
例如，对于上述两个资源集合的场景，可以通过一个比特指示所选的资源集合，例如比特0表示资源集合1，比特1表示资源集合2。这种方式节约了反馈资源，提高了上报效率。
终端上报参考信号资源集合索引外还可以上报该资源集合中的资源信息。该资源信息用于表示所上报的测量结果是使用所上报的资源测量的，或终端认为该资源集合中被上报的资源为有效测量资源；例如：有效测量资源可以满足下面一个或多个条件或功能：对测量结果贡献最大，或终端认为主要由该上报的资源确定了上报的测量结果，或建议基站使用上报的资源进行传输。
例如，基站配置了4个资源集合，每个集合包含2个参考信号资源，并配置或指示终端对每个资源集合进行合并测量。终端测量后选择资源集合2进行上报，同时上报参考信号集合2的中1个资源(例如资源2)或多个资源(例如资源2,3)，则表示终端根据资源2(或资源2,3)得到了测量结果，或终端推荐基站使用资源2(或资源2,3)对应 的波束进行信号传输。
终端上报的资源集合的标识或索引可以与基站配置的合并测量指示关联。例如，基站配置了Combination On＝a和Combination On＝b两个合并测量指示，终端对包含上述两种合并测量指示参考信号分别进行合并测量后，得到2个测量结果。如果终端要上报Combination On＝a对应的多个资源的共同索引，则可以用与Combination On＝a对应的标识来表示。例如：比特0表示Combination On＝a的多个资源(或资源和资源集合的组合)。同样的，如果终端要上报Combination On＝b对应的多个资源的共同索引，则可以用与Combination On＝b对应的标识来表示，例如比特1表示Combination On＝b的多个资源(或资源和资源集合的组合)。
另一个例子中，如果基站配置了多个多端口参考信号资源，并指示终端对每个多端口参考信号资源启动合并测量且上报所述多个资源中的N个资源。则终端应对每个参考信号资源分别测量后，上报N个资源的索引和/或测量结果，N可以通过协议约定，或基站为终端配置，或终端自行确定。N个资源可以为所述多个资源中测量结果最好N个，N＝1时，则为测量结果最好的多端口参考信号资源。
可选的，终端上报资源索引外，还可以额外上报端口选择信息，用于指示所上报的测量结果是使用所上报的端口测量的，或终端认为该多端口参考信号资源中被上报的端口为有效测量端口；例如：有效测量端口可以满足下面一个或多个条件或功能：对测量结果贡献最大，或终端认为主要由该上报的端口确定了上报的测量结果，或建议基站使用上报的端口进行信号传输。
例如，基站为终端配置了4个4端口参考信号资源，并配置或指示终端对每个4端口参考信号资源进行合并测量。终端测量后选择参考信号资源3进行上报，同时上报参考信号资源3的N＝2个端口，表示终端使用这两个端口得到的测量结果，或终端推荐基站使用这两个端口进行信号传输。
104，基站可以将上报的资源集合用于波束指示(图中未示出)。
例如：基站向终端下发波束配置信息，所述波束配置信息包括所述上报的资源集合与上行信道或下行信道的关联关系。具体的，可以为终端上报的资源集合对应的终端接收波束与终端的上行信道的发送波束的关联关系，或终端上报的资源集合对应的终端接收波束与终端的下行信道的接收波束的关联关系。
如果终端向基站上报了参考信号资源集合2，基站可以将资源集合2配置到传输状态指示(TCI)中，例如：
TCI#1
{参考信号:参考信号资源集合2
准同位信息：空域准同位}
基站可以将终端的信道或参考信号资源关联到该TCI状态下，表示终端应使用该参考信号资源集合2对应的接收波束接收被关联的信道或信号。所述参考信号资源集合2对应的接收波束可以为终端接收并测量参考信号资源集合2使用的接收波束。其中，关联方式本申请不限定，可以使用直接配置关联关系、或利用DCI、MAC-CE或DCI等通过关联TCI状态进行指示。
可选的，基站也可以将参考信号资源集合2作为波束指示或空间传输信息关联给下行信号(信道)或上行信号(信道)，例如，通过QCL指示实现上述关联关系。
例如，基站为终端配置SRS(sounding RS)资源，并将SRS资源的发送波束信息关联到参考信号资源集合2，则终端应使用测量该参考信号资源集合2关联的接收波束所对应的发送波束发送被关联的SRS资源。
可选的，基站可以不使用资源集合的索引进行指示，而是使用资源集合中的某一个资源的索引进行指示，该资源所在资源集合为一个可合并测量的资源集合。例如，基站配置了参考信号资源集合2：{CSI-RS#1,CSI-RS#2}，并指示该集合为可合并测量的参考信号资源集合。当基站使用CSI-RS#1作为上行或下行信号的波束指示的参考信号时，终端应使用测量该参考信号集合2的接收波束接收CSI-RS#1关联的信号或信道，或使用测量该参考信号集合2的接收波束所对应的发送波束发送CSI-RS#1关联的信道或信号。
本申请实施例所描述都是基于下行参考信号描述，下行参考信号以CSI-RS做了列举，其它下行参考信号也同样适用。另外，相同的机制可以用于上行参考信号(如SRS等)。即基站配置一个或多个SRS资源集合，终端发送SRS资源集合后，基站根据测量结果选择相应的资源集合进行上行或下行波束指示。
例如，基站为终端配置多个SRS资源集合，每个集合包括一个或多个SRS资源，终端根据基站配置的波束指示使用对应发送波束发送SRS资源，波束指示的方式本申请不限定，例如：可以通过将SRS资源关联到某CSI-RS或某SRS，表示使用接收该CSI-RS的接收波束对应的发送波束，或使用该SRS对应的发送波束，发送被关联的SRS资源。基站接收终端发送的SRS资源集合并进行测量，根据测量结果，选择其中一个或多个资源集合，并将选择的资源集合的索引配置给终端，作为上行/下行信道或参考信号的波束指示，表示终端应使用发送该SRS资源集合中的任意发送波束发送被关联的上行信道或信号，或使用发送该SRS资源集合中的任意发送波束对应的接收波束接收被关联的下行信道或信号。其它细节可参考上述方法实施例，不再详述。
上述实施例中的测量结果可以是以下测量量中的一项或多项的测量结果：参考信号接收功率RSRP、参考信号接收质量RSRQ、信号与干扰噪声比SINR和接收信号强度指示RSSI。
上述实施例中，基站向终端下发的指示或通知，或者基站触发终端，均可以通过RRC，DCI或MAC-CE进行。
还应理解，图3中的例子仅仅是为了便于本领域技术人员理解本申请实施例，并非要将本申请实施例限于例示的具体场景。本领域技术人员根据图3的例子，显然可以进行各种等价的修改或变化，这样的修改或变化也落入本申请实施例的范围内。
还应理解，本申请实施例的各个方案可以进行合理的组合使用，并且实施例中出现的各个术语的解释或说明可以在各个实施例中互相参考或解释，对此不作限定。
还应理解，在本申请的各种实施例中，上述各过程的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本申请实施例的实施过程构成任何限定。
上文详细描述了根据本申请实施例的波束测量的方法。下面将结合图6至图8描述根据本申请实施例的波束测量的装置。应理解，方法实施例所描述的技术特征同样适用 于以下装置实施例。

还应理解，装置400中的各个模块可以通过软件和/或硬件形式实现，对此不作具体限定。换言之，装置400是以功能模块的形式来呈现。这里的“模块”可以指特定应用集成电路ASIC、电路、执行一个或多个软件或固件程序的处理器和存储器、集成逻辑电路，和/或其他可以提供上述功能的器件。可选地，在一个简单的实施例中，本领域的技术人员可以想到装置400可以采用图7所示的形式。处理模块410可以通过图7所示的处理器501和存储器502来实现。收发模块420可以通过图7所示的收发器503来实现。具体的，处理器通过执行存储器中存储的计算机程序来实现。可选地，当所述装置400是芯片时，那么收发模块420的功能和/或实现过程还可以通过管脚或电路等来实现。可选地，所述存储器为所述芯片内的存储单元，比如寄存器、缓存等，所述存储单元还可以是所述计算机设备内的位于所述芯片外部的存储单元，如图7所的存储器502。
