技术领域
本公开实施例涉及通信技术领域，尤其涉及一种波束测量处理方法及装置。
背景技术
大规模多入多出(Massive MIMO)技术使用大规模天线阵列，能够极大地提升系统频带利用效率，支持更大数量的接入用户。因此各大研究组织均将massive MIMO技术视为下一代移动通信系统中最有潜力的物理层技术之一。在massive MIMO技术中包括全数字赋形技术以及数模混合波束赋形技术。其中，数模混合波束赋形技术在传统的数字域波束赋形基础上，在靠近天线系统的前端，在射频信号上增加一级波束赋形。相比于全数字赋形技术来说，模拟赋形能够通过较为简单的方式，使发送信号与信道实现较为粗略的匹配，能够将性能与复杂度进行良好的折中，在高频段大带宽或天线数量很大的系统中具有较高的实用前景。
模拟波束赋形是全带宽发射的，并且每个高频天线阵列的面板上每个极化方向阵元仅能以时分复用的方式发送模拟波束。模拟波束的赋形权值是通过调整射频前端移相器等设备的参数来实现。目前通常是使用轮询的方式进行模拟波束赋形向量的训练，即网络侧首先下发波束测量的配置信息，接着每个天线面板每个极化方向的阵元以时分复用方式依次在约定时间依次发送训练信号(即发射波束)，终端经过对发射波束与自身拥有的接收波束进行测量后，反馈最优的发射波束标识以及测量出的最优发射波束所在波束对链路的质量(如接收功率)，供网络侧在下一次传输业务时采用最优的模拟发射波束来实现数据传输。
对于上述测量过程的波束管理中，可以使用发射波束扫描(Tx beam sweeping)和接收波束扫描(Rx beam sweeping)来测量出最优的发射接收波束对链路(BPL：beam pair link)。在Tx/Rx beam sweeping的过程中，还定义了时间分割(time unit)，对应一个或多个正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号，也即整数倍个OFDM符号，每个time unit可以划分为多个sub-time unit(子时间分割)。目前常用的测量方式包括如下选项：
选项1、在每个time unit内发射波束不变，在不同time unit中改变发射波束；(为便于表述，后文中将选项方式表述为Rx波束扫描方式)；
选项2、在每个time unit内的不同sub-time unit改变发射波束，在不同的time unit中发射波束相同；(为便于表述，后文中将选项方式表述为Tx波束扫描方式)；
选项3：在一个time unit内发射波束不变，在另一个time unit内的不同sub-time unit改变发射波束。
然而，在对相关技术研究的过程中发明人发现，相关技术中的测量方式都是UE在一个time unit内要完成一个Tx beam与全部Rx beam所形成的波束对链路质量测量或一个Rx beam与全部Tx beam所形成的波束对链路质量测量，在这一测量过程中并没有考虑到UE的测量能力，也即用户设备(User Equipment，UE，也可以称为移动终端)在一个OFDM符号能够支持的最大测量次数，这样可能导致波束测量的时间资源被浪费的情况发生。

具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例中的附图，对本公开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公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。本申请中和/或表示所连接对象至少其中之一。
为便于理解本公开实施例与相关技术中的测量方式的区别，下面对相关技术中的测量方式进行说明。
首先对于背景技术中选项1以及选项2这两种测量方式进行举例说明，由于选项3为上述两种选项的结合，在此不再赘述。
假设网络侧共有4个Tx波束，UE侧共有2个Rx波束。
参见图1，如果采用选项1的Rx波束扫描方式，那么每个Tx波束将占用一个time unit，共需4个time unit。每个time unit划分为2个sub-time unit，对应2个Rx波束。UE在1个time unit中完成一个Tx波束和所有Rx波束(Rx beam 1以及Rxbeam 2)的BPL质量测量，在4个time unit中完成所有Tx波束(Tx beam 1、Tx beam 2、Tx beam 3以及Tx beam 4)和所有Rx波束的BPL质量测量。
参见图2，如果采用选项2的Tx波束扫描方式进行测量，那么每个Rx波束占用一个time unit，共需2个time unit。每个time unit划分为4个sub-time unit，对应4个Tx波束。UE在1个time unit中完成所有Tx波束和一个Rx波束的BPL质量测量，在2个time unit中完成所有Tx波束和所有Rx波束的BPL质量测量。
其中，对于图1以及图2示出的两种测量方式，每种测量方式中每个time unit占用的OFDM符号个数可以是不同的。例如，如果UE可以支持在一个OFDM符号内利用IFDMA(Interleaved Frequency Division Multiple Access，交织频分多址)或large subcarrier spacing(大子载波间隔)等技术完成两次波束测量，那么对于图1，每个time unit就占用1个OFDM符号，共需4个time unit，即共4个OFDM符号，每个time unit分为2个sub-time unit，每个sub-time unit占用1/2个OFDM符号长度；对于图2，每个time unit就占用2个OFDM符号，共需2个time unit，即共4个OFDM符号，每个time unit分为4个sub-time unit，每个sub-time unit占用1/2个OFDM符号长度。
对于图1和图2示出的情况来说，虽然采用相关技术中的测量方法没有造成sub-time unit的时间资源浪费，但在实际应用中，采用相关技术中的测量方法还可能出现以下情况。
一种情况参见图3，设网络侧的Tx波束有3个，UE侧的Rx波束有2个，采用选项2的Tx波束扫描方式进行测量，UE可以支持每个OFDM符号内完成2次测量。由于采用选项2的方式是在每个time unit中对3个Rx波束与3个Tx波束进行BPL质量测量，因此至少需要2个OFDM符号才能完成一个time  unit的测量过程。因此，网络侧会在下发的CSI-RS配置消息中通知UE一个time unit占用2个OFDM符号，并且每个time unit包括4个sub-time unit。
那么，UE将在第1个OFDM符号内完成Tx beam 1+Rx beam 1和Tx beam 2+Rx beam 1的测量，在第2个符号内完成Tx beam 3+Rx beam 1。由图3可以看出此时每个time unit中还剩下一个sub-time unit处于空闲状态。而根据选项2的规定，在每个time unit内Rx波束不变，即使在当前的OFDM符号未结束之时已完成了当前Rx波束与所有Tx波束的测量，也即一个time unit对应的BPL质量测量结束了，也只能等待到下一OFDM符号来临时才能进行下一轮的BPL质量测量，这就造成了时间资源被浪费的情况。
另一种情况参见图4，其中Tx波束的个数、Rx波束的个数、扫描的方式、UE可支持的一个OFDM符号内做几次波束测量均与图3示出的情况相同，区别仅在于每个time unit本来如图4中的虚线框所示划分为4个sub-time unit，这里根据Tx波束的个数将一个time unit划分成3个sub-time unit，这种情况虽然没有sub-time unit空闲，但对于每个sub-time unit来说训练波束时间变长，同样也造成了时间资源被浪费的情况。
基于此，第一方面，本公开实施例提供了一种波束测量处理方法，如图5、6所示，包括：
S104、在进行第一模式的波束对的链路质量测量时，确定移动终端针对当前的发射波束完成一轮接收波束轮换的第一完成时刻；
其中，这里的第一模式的波束对的链路质量测量，包括：在每一次发射波束切换之前，各个接收波束进行轮换，并对轮换所组成的各个波束对进行测量；在完成对各个波束对的链路质量测量之后，切换到下一个发射波束，进行下一轮的接收波束轮换；直至完成各个发射波束与各个接收波束所组成的所有波束对的链路质量测量。也就是说，第一模式的波束对的链路质量测量为在每个time unit中网络侧固定Tx beam做重复发射、且移动终端做Rx beam sweeping的测量模式(可以参考图1示出测量方式)。
这里的“针对当前的发射波束完成一轮接收波束轮换”的过程具体是指：Tx beam在时域上重复发射，而Rx beam轮换进行接收，UE对这个Tx beam与各个Rx beam所组成的各个波束对的质量进行测量，这样一个过程叫做针 对当前的发射波束完成一轮接收波束轮换。
此外，这里的第一完成时刻既可以为一个OFDM符号的结束时刻，也可以为一个OFDM符号的中间时刻，具体为哪个时刻需要根据实际的测量情况来看。
S105、自第一完成时刻起发射下一个发射波束。
其中，这里的自第一完成时刻起发射下一发射波束可能包括：自第一完成时刻起立即发射下一波束。还可能包括自第一完成时刻起间隔一段时间再进行下一发射波束的发射。例如，由于网络侧设备的射频器件的影响，网络侧设备实现由一个发射波束调整切换至另一个发射波束这一过程可能需要花费一段时间，因此网络侧设备可能自第一完成时刻起需要间隔这一切换时间再进行下一发射波束的发射。当然，这一切换时间也可以人为设置，本公开实施例对此不作具体限定。
和/或，
S104’、在进行第二模式的波束对的链路质量测量时，确定网络侧设备针对当前的接收波束完成一轮发射波束轮换的第二完成时刻；
其中，这里的第二模式的波束对的链路质量测量，包括：在每一次接收波束切换之前，各个发射波束进行轮换，并对轮换所形成的各个波束对进行测量；在完成对各个波束对的链路质量测量之后，切换到下一个接收波束，进行下一轮的发射波束轮换；直至完成各个发射波束与各个接收波束所组成的所有波束对的链路质量测量。也就是说，第二模式的波束对的链路质量测量为在每个time unit中移动终端固定Rx beam做重复接收、且网络侧做Tx beam sweeping的测量模式(可以参考图2示出测量方式)。
S105’、自第二完成时刻起进行下一轮的发射波束轮换。
这里的进行下一轮的发射波束轮换是指：各个发射波束轮流发射。此时UE一侧只测量一个接收波束与各个发射波束所组成的波束对链路质量。此外，与S102中的情况类似，这里的自第二完成时刻起进行下一轮发射波束的轮换也可以为立即发射，也可以为间隔一端时间发射，本公开实施例对此不作具体限定。
此外，这里的第二完成时刻与第一完成时刻类似，也可以为一个OFDM符号的结束时刻，也可以为一个OFDM符号的中间时刻，具体为哪个时刻需要根 据实际的测量情况来看。
本公开实施例提供的波束测量处理方法中，网络侧设备(例如基站)通过在确定完成一轮接收波束轮换后发射下一个发射波束，或在确定完成一轮发射波束轮换后进行下一轮发射波束的轮换，从而当一个time unit已经完成但还未到当前所在的OFDM符号的结束时间时，网络侧设备无需等待当前OFDM符号结束，也即无需满足一个time unit必须占用整数倍OFDM符号这样的条件，可以为非整数倍的OFDM符号直接进行下一个time unit的波束测量，从而可以充分利用UE的最大测量能力，在UE能力能够支持的情况下最大限度地压缩整个波束测量的时间，有效节约时间资源，以使得更多资源可用于数据传输。
需要说明的是，本公开实施例提供的方法主要是针对的是下行链路的波束管理，因此这里的发射波束就是网络侧的发射波束，接收波束就是终端的接收波束，后文中不再对此内容进行赘述。
基于上述实施例，在波束对的链路质量测量之前，本公开实施例提供的方法还可以包括：
S101、确定发射波束的个数和接收波束的个数，并根据发射波束的个数确定对应的各个发射波束；
在实际应用中，这里的Tx波束的个数对于网络侧设备来说是已知的，所以只需要根据Tx波束的个数来选择本次要测量的Tx波束；
这里的Rx波束的个数可以根据UE上报的其自身拥有的Rx波束的个数来确定，具体来说经过S101确定的Rx波束的个数可以小于或等于UE的自身拥有的Rx波束的个数。在小于时也即本次仅要测量UE的其中几个Rx波束，在等于时也即本次要测量UE的所有Rx波束。
S102、根据移动终端的最大划分时间分割数确定符号划分信息；其中，最大划分时间分割数是指在满足设定条件时移动终端所支持的对OFDM符号划分的时间分割的最大个数；设定条件包括：在每个时间分割内，移动终端能够完成至少一次波束对的链路质量测量；符号划分信息为在一个OFDM符号内需要划分的时间分割的个数或时间分割的时长。
这里的UE的最大划分时间分割数其实反映的是UE的最大能力。不难理 解的是，这里的对于一个OFDM符号来说，一种类型的OFDM符号的时长是固定的，那么UE所支持的对OFDM符号划分的时间分割的最大个数也可以描述为：UE在一个OFDM符号内能够测量的最大次数，或在一个OFDM符号内能够划分的时间单元(time unit)的最大个数等等，可以翻译为number of symbol partition within each OFDM symbols。当然还可以有其他的描述方式，只要是体现对OFDM符号的划分且这样的划分能够体现UE的测量能力的都与本公开实施例中的“对OFDM符号划分的时间分割的最大个数”的概念等同。同样地，参见图7，S102中“时间分割的时长”也可以描述为：UE每次测量的时长，或每个被划分的子时间单元(sub-time unit)的时长等等。这些也都是等同的概念，其实质都是相同的。
S103、将CSI-RS配置信息发送至移动终端，所述CSI-RS配置信息用于指示发射波束的个数、接收波束的个数以及所述符号划分信息；
这里的“CSI-RS配置信息用于指示Tx波束的个数、Rx波束的个数以及符号划分信息”可以理解为用于使得UE获知这些参数。使UE能够获知这些参数的方式有很多种。具体来说，CSI-RS配置信息可以直接包含Tx个数的数值、Rx个数的数值、以及一个OFDM符号进行波束测量次数的数值或每次波束测量时长的数值，从而UE侧可以直接从CSI-RS配置信息提取这些数值获知这些参数。CSI-RS配置信息还可以包含与这些参数具有相关性的其他参数的值，从而UE侧可以根据这些其他参数的值基于约定好的计算方式获知这些信息。CSI-RS配置信息还可以包含能够标识这些参数的标识信息，从而UE在接收到这些标识信息之后可以根据与网络侧设备事先约定好的标识信息与参数的对应关系获知这些参数。进一步地，这里的标识信息可以为多个，且与各个参数可以为一对一或一对多的关系，也可以仅通过一个标识信息对应所有的参数，本公开实施例对比不作具体限定。
进而，上述步骤S104可以为：
S1041、根据符号划分信息以及接收波束的个数，确定移动终端针对当前的发射波束完成一轮接收波束轮换的第一完成时刻；
也就是说，网络侧设备根据符号划分信息能够获知UE进行一次测量所需的时间，根据接收波束的个数能够获知进行一轮接收波束轮换所需的时间， 从而能够获知进行一轮接收波束轮换的第一完成时刻。
上述步骤S104’可以为：
S1041’、根据符号划分信息以及发射波束的个数，确定针对当前的接收波束完成一轮发射波束轮换的第二完成时刻；
也就是说，网络侧设备根据符号划分信息能够获知UE进行一次测量所需的时间，根据发射波束的个数能够获知进行一轮发射波束轮换所需的时间，从而能够获知进行一轮发射波束轮换的第二完成时刻。
本公开实施例提供的方法中，网络侧设备可以根据不同的测量需求对测量的配置参数进行配置，同时将该配置参数下发至UE以供UE与其配合进行测量。且当一个time unit已经完成而还未到当前所在的OFDM符号的结束时间时，网络侧设备可以直接进行下一个time unit的波束测量，无需等待当前OFDM符号结束，从而可以充分利用UE的最大测量能力，在UE能力能够支持的情况下最大限度地压缩整个波束测量的时间，有效节约时间资源，以使得更多资源可用于数据传输。
在具体实施时，在S103中下发的CSI-RS配置信息直接下发参数的情况时，CSI-RS配置信息可以包括如下任意一种及任意组合：所述符号划分信息、发射波束的个数、接收波束的个数、CSI-RS资源配置相关信息、CSI-RS资源个数相关信息、每个CSI-RS资源所关联的时域重复次数、所用OFDM符号的总个数、测量模式的指示标识、符号间隔数、CSI-RS周期、波束选择方式指示信息、波束对的链路质量测量激活信息以及在每个时间分割中支持的CSI-RS资源或CSI-RS端口数。
从而UE一侧可以根据这些信息直接或间接获知Tx波束的个数、Rx波束的个数以及符号划分信息。本公开实施例为UE提供了多种参数的组合，从而UE在获取波束个数及符号划分信息时能够更加灵活。
UE侧如何获知Tx波束的个数、Rx波束的个数以及符号划分信息的具体过程将在后文中进行详细说明。当然，上述所列举的参数中还包含一些其他控制波束训练的参数，例如用于指示进行首先做Tx扫描还是首先做Rx扫描的测量模式的指示标识，用于指示波束测量周期的CSI-RS周期等等。相应地，UE一侧也会根据这些参数对波束对链路质量测量进行相应的控制，具体的控 制方式同样会在后文中进行详细说明。
为了更进一步理解本公开实施例提供的方法，下面举几个示例来具体说明本公开实施例提供的方法是如何节约时间资源的。
一、举例1
设Tx beam有4个，Rx beam有2个。UE支持每个OFDM符号内划分4个时间分割，也即可以进行4次测量。
(一)采用相关技术中的波束测量方式
采用相关技术进行测量可以有两种方式：一种方式下，网络侧下发的CSI-RS配置信息可以包括：
● CSI-RS资源个数：4
● 每个CSI-RS资源相关联的时域重复次数：2
● CSI-RS RE pattern、CSI-RS天线端口数以及CSI-RS周期
● 选项1做beam sweeping(也即首先做Rx波束扫描方式)
● time unit个数：4个
● time unit长度：1个符号
● sub-time unit：1/4 time unit
参见图8，UE侧在接收到上述配置信息后与网络侧配合开始进行波束测量。由于采用的是首先做Rx波束扫描方式，因此对于一个time unit来说仅需要进行两次测量就可以完成当前Tx波束与所有Rx波束的测量，例如第一个time unit中只测量Tx beam 1+Rx beam 1以及Tx beam 1+Rx beam 2。由于UE支持每个OFDM符号内进行4次测量，而相关技术选项中规定一个time unit至少对应一个OFDM符号，因此这里的一个time unit占用一个OFDM符号。由图8不难看出，在一个OFDM符号内由于UE支持的时间分割的个数(也即测量次数)4大于完成一个time unit所需要测量的次数2，因此会有两个sub-time unit处于空闲状态，这两个sub-time unit的空闲就造成了时间资源的浪费。
另一种方式下，CSI-RS配置信息包括：
● CSI-RS资源个数：4
● 每个CSI-RS资源相关联的时域重复次数：2
● CSI-RS RE pattern、CSI-RS天线端口数、CSI-RS周期。
● 选项1做beam sweeping
● time unit个数：4
● time unit长度：1个符号
● sub-time unit：1/2 time unit
参见图9，可以看出这种方式下本来UE可以支持每个符号内划分4个时间分割，但是根据Rx beam数仅分了2个时间分割。此时，虽然没有sub-time unit处于空闲状态，但将原本能划分为四个的时间分割划分为两个无疑会造成每次测量时间的变长，导致训练所有波束的总时间变长，也会造成时间资源的浪费。
(二)采用本公开实施例提供的波束测量方式
由于Tx beam有4个，Rx beam有2个，因此需要进行的总测量数为8次。因为UE支持每个OFDM符号内可以进行4次测量，因此完成所有的测量只需要2个OFDM符号。此外，在本实施例中，UE侧与网络侧可以预先约定首先固定Tx beam重复发射且做Rx beam sweeping，也即首先做Rx波束扫描方式。则网络侧下发的CSI-RS配置信息可以包括：
● 发射波束个数：4
● 接收波束个数：2
● CSI-RS RE pattern，CSI-RS天线端口数，CSI-RS周期等
● 所用OFDM符号数：2
● 每个OFDM符号内的划分时间分割数:4
● 在每个OFDM符号的划分时间分割中支持的CSI-RS资源或CSI-RS端口数：缺省
UE侧在获得这些配置信息后如何获知波束测量所必要的参数将在后文中进行详细介绍，在这里重点想要说明的是采用本公开实施例提供的方法UE侧与网络侧是如何能够尽可能的压缩整个波束的训练时间的。
参见图10，对于网络侧设备来说，第一个time unit中在确定了Rx beam 1以及Rx beam 2扫描完成之后，可以自完成时刻起直接开始Tx beam 2的发射，也即直接进入了第二个time unit，这里的time unit为1/2个OFDM 符号时长。接下来的过程以此类推，直至完成Tx beam 4与所有Rx波束的扫描。
从图8、图9以及图10的对比中不难发现，本公开实施例与相关技术最大的不同之处就在于：相关技术中1个time unit只能占用整数倍个OFDM符号。以Rx波束扫描方式来说，如果Rx波束的个数不是UE在一个OFDM符号内的最大测量次数的整数倍(在这里Rx波束个数为2，最大测量次数为4)，由于网络侧设备在每个time unit中在所有的Rx波束扫描结束之时无法切换至下一个Tx波束，而一个time unit又只能占用整数倍个OFDM符号，因此网络侧切换Tx波束的时间只能为整数倍个OFDM符号所在的时刻。在这种前提下，无论是采用图8所示的按UE的最大能力来进行测量，还是采用图9所示的延长每次测量的时间，都会造成时间资源的浪费，最后完成所有的波束测量总共需要4个OFDM符号。
而在本公开实施例中，1个time unit既可以整数倍个OFDM符号，又可以占用非整数倍个OFDM符号，图10所示的情况就是1个time unit可以占用1/2个OFDM符号，那么在完成一个time unit之后就可以在当前的OFDM符号中切换至下一个Tx波束，最后完成所有的波束测量只需要2个OFDM符号，从而能够充分利用UE的测量能力，有效节约整个波束训练时间。本公开实施例提供的方法对于Tx波束扫描方式也是同理，在此不再赘述。
二、举例2
设Tx beam有3个，Rx beam有4个。UE支持每个符号内划分6个时间分割。
(一)采用相关技术中的波束测量方式
在举例2中仅列出相关技术中不延长每次波束测量时间的测量方式。在这种方式下，网络侧设备下发的CSI-RS配置信息可以包括：
● CSI-RS资源个数：3
● 每个CSI-RS资源相关联的时域重复次数：4
● CSI-RS RE pattern、CSI-RS天线端口数、CSI-RS周期。
● 选项1做beam sweeping
● time unit个数：3
● time unit长度：1个符号
● sub-time unit：1/6time unit
参见图11，与图8类似，由于一个time unit内不能进行Tx波束的切换且一个time unit对应一个OFDM符号，因此每个time unit中的最后两个sub-time unit处于空闲状态，最后完成所有的波束测量总共需要3个OFDM符号，造成了时间资源的浪费。
(二)采用本公开实施例提供的波束测量方式
以首先做Rx波束扫描方式为例，完成所有测量共需2个OFDM符号，每个符号有6个划分时间分割。网络侧下发的CSI-RS配置信息包括：
● 发射波束个数：3
● 接收波束个数：4
● CSI-RS RE pattern，CSI-RS天线端口数，CSI-RS周期等
● 所用OFDM符号数：2
● 每个OFDM符号内的划分时间分割数:6
● 在每个OFDM符号的划分时间分割中支持的CSI-RS资源或CSI-RS端口数：缺省
参见图12，UE在接收到上述配置信息后可以参照图12与网络侧设备进行波束测量。通过图11与图12的对比不难看出，本公开实施例提供的方法中一个time unit可以对应非整数倍个OFDM符号，例如图12所示的2/3个OFDM符号，从而网络侧可以在第2/3个OFDM符号处开始下一个Tx波束的发射，最后完成所有的波束测量总共需要2个OFDM符号，相比于图11的情况节省了一个OFDM符号，节省了整个波束训练过程的时间。
图12示出的是首先做Rx波束扫描方式，下面再举一个首先做Tx波束扫描方式的例子来进一步说明本公开实施例提供的方法。
网络侧下发的CSI-RS配置信息包括：
● 发射波束个数：3
● 接收波束个数：4
● CSI-RS RE pattern，CSI-RS天线端口数，CSI-RS周期等
● 所用OFDM符号数：2
● 每个OFDM符号内的划分时间分割数:6
● 在每个OFDM符号的划分时间分割中支持的CSI-RS资源或CSI-RS端口数：缺省
参见图13，对于网络侧设备来说，在第一个time unit中，在确定自身已经完成了Tx beam 1、Tx beam 2、Tx beam 3的扫描之后，在扫描结束之时开启下一轮的Tx波束扫描。与图12相同，完成所有测量也总共需要2个OFDM符号，相比于图11所示的方式节省了一个OFDM符号，节约了整个波束训练过程的时间。
总而言之，本公开实施例提供的方法可以充分利用UE的测量能力，在每个OFDM符号内都可以改变Tx beam或Rx beam，也即一个time unit可以占用非整数倍个OFDM符号(例如1/2个符号，2/3个符号，当然也可以为整数倍)，从而尽可能快的完成所有波束测量，降低波束管理过程的时延，不会产生波束管理的时间资源浪费，以使得更多资源可用于数据传输。
可以理解的是，上述内容仅是网络侧设备向一个UE下发配置信息并与UE配合完成波束训练的情况，在具体实施时，还有可能出现多个UE的情况。
假设网络侧的Tx beam有4个，UE1有2个Rx beam，UE2也有2个Rx beam，但是UE1支持在一个符号内完成2次beam测量，UE2支持在一个符号内完成4次beam测量。若采用相关技术中的测量方法，那么对于UE1的CSI-RS配置信息包括如下：
● 选项1做beam sweeping
● time unit个数：4个
● time unit长度：1个符号
● sub-time unit：1/2 time unit
UE1在进行波束测量时可以参照图1所示的方式进行测量。
对于UE2的CSI-RS配置信息包括如下：
● 选项2做beam sweeping(如果采用选项1，则所需符号个数更多)
● time unit个数：2个
● time unit长度：1个符号
● sub-time unit：1/4 time unit
UE1在进行波束测量时可以参照图1所示的方式进行测量。
可见，对不同UE需要给出分别不同的CSI-RS配置信令，当UE数很多时，所需的信令开销很大。另外，当同时进行beam sweeping的UE较多时，UE2也需要和UE1一样采用选项1的扫描方式，那么此时UE2则也会存在sub-time unit资源浪费情况。
据此，本公开实施例提供的方法中，在S103中发送CSI-RS配置信息可以包括：向多个UE发送相同的CSI-RS配置信息。其中，针对不同的UE能力，在确定一个OFDM符号内对波束能够测量的最大次数时选择多个UE对应的各个最大次数中的最小值，也即以能力最小的UE来确定一个OFDM符号内对波束能够测量的最大次数，再根据这一最大次数来确定符号划分信息，从而能够在尽可能压缩波束训练时间的情况下满足所有UE的能力需要。
此外，上述所述情况均为网络侧设备只设置有一个天线面板的情况，在只有一个天线面板的情况下，在一个OFDM符号内的一个时间分割中，网络侧设备仅能够发射一个Tx波束，且该波束仅能够对应一个CSI-RS资源。然而，在实际情况中，参见图14，还有可能出现网络侧设备设置多个天线面板(Panel)的情况，此时，在一个时间分割中各个面板均能够发射一个Tx波束，且在这一时间分割中可以支持多个CSI-RS资源。
在这一情况下，当网络侧设备下发CSI-RS配置信息时，该配置信息除了包含用于指示发射波束的个数、接收波束的个数以及所述符号划分信息的内容，还可以包括在每个OFDM符号的划分时间分割中支持的CSI-RS资源或CSI-RS端口数，其中这里的支持的资源或端口数即代表了支持的同时发射的发射波束个数。对于网络侧基站有一个传输接收点(TRP，Transmission Reception Point)时，则代表了该TRP的天线面板个数。对于网络侧基站有多个TRP时，则代表了这些TRP总的天线面板个数。特别的，当网络侧基站的多个TRP都只有一个天线面板时，则代表了该网络侧基站的TRP个数。当UE获知这一信息之后，即可以根据这一信息获得网络侧能够同时发射的发射波束个数。
举例来说，设网络侧基站只有一个TRP，且该TRP有2个panel，每个panel有2个Tx beam，UE有2个Rx beam。UE支持每个符号内划分2个时 间分割。CSI-RS配置信息中包括：
● Tx beam个数：4
● Rx beam个数：2
● 所用OFDM符号个数：2。
● 每个符号内划分单元数：2。
● 每个划分时间分割内支持的CSI-RS资源数或CSI-RS端口数：2
在UE获取这些参数后即可以根据这些参数进行波束测量。参见图15，Tx beam 1以及Tx beam 3为Panel 1发射的Tx波束，Tx beam 2以及Tx beam 4为Panel 2发射的Tx波束。在一个time unit中，Panel 1与Panel 2同时发射Tx beam 1和Tx beam 2。但由于UE支持每个符号内划分2个时间分割，也即最多做两次波束测量，因此一个time unit需要占用两个OFDM符号。具体的波束测量的过程与上述单panel的过程类似。图15示出了首先做Rx波束扫描方式的波束测量过程，对于Panel 1来说，当其确定针对于Tx beam 1的Rx beam 1以及Rx beam 2的扫描完成时，则在完成之时开始发射Tx beam 3；当为首先做Tx波束扫描方式时，对于Panel 1来说，当其确定针对于Rx beam 1的Tx beam 1以及Tx beam 3的扫描完成时，则在完成之时开始下一轮的Tx波束扫描。
本公开实施例提供的方法通过在CSI-RS配置信息中携带用于指示每个划分时间分割内支持的CSI-RS资源数或CSI-RS端口数的信息，从而能够支持多TRP、多Panel情况下的多波束同时测量，提高波束管理过程的速度。当然在实际应用中，除了图14所示多个CSI-RS资源对应不同天线面板的情况，还有可能出现一个CSI-RS资源的多个端口对应不同天线面板的情况，其实施的方式与上述方式类似在此不再赘述。此外，这些面板可以位于一个TRP上，也可以位于多个TRP上，本公开实施例对此不做具体限定。
本公开实施例提供的波束测量处理方法中，网络侧设备可以下发多种组合的CSI-RS配置信息，以供UE获知本次测量任务的具体内容同时与网络侧设备配合在一个time unit结束之后就进入下一个time unit的测量，无需等待OFDM符号的结束，从而能够充分利用UE的最大能力，避免出现时间资源浪费的情况。此外本公开实施例提供的方法还能够支持多TRP、多Panel 的模式，能够更广泛的适应于5G通信领域。
基于同样的思想，第二方面，本公开实施例提供了另一种波束测量处理方法，如图16、17所示，包括：
S202、在进行第一模式的波束对的链路质量测量时，确定移动终端针对当前的发射波束完成一轮接收波束轮换的第一完成时刻；
其中，这里的第一模式的波束对的链路质量测量，包括：在每一次发射波束切换之前，各个接收波束进行轮换，并对轮换所形成的各个波束对进行测量；在完成对各个波束对的链路质量测量之后，切换到下一个发射波束，进行下一轮的接收波束轮换；直至完成各个发射波束与各个接收波束所组成的所有波束对的链路质量测量
S203、自第一完成时刻起，进行下一轮的接收波束轮换；
和/或，
S202’、在进行第二模式的波束对的链路质量测量时，确定网络侧设备针对当前的接收波束完成一轮发射波束轮换的第二完成时刻；
其中，第二模式的波束对的链路质量测量，包括：在每一次接收波束切换之前，各个发射波束进行轮换，并对轮换所形成的各个波束对进行测量；在完成对各个波束对的链路质量测量之后，切换到下一个接收波束，进行下一轮的发射波束轮换；直至完成各个发射波束与各个接收波束所组成的所有波束对的链路质量测量。
S203’、自第二完成时刻起，切换至下一个接收波束进行测量。
由于对第一模式、第二模式、第一完成时刻以及第二完成时刻在第一方面中已经进行了详细介绍，在此不再赘述。
本公开实施例提供的波束测量处理方法中，UE设备在确定完成一轮接收波束轮换后进行下一轮的接收波束轮换，或在确定完成一轮发送波束轮换后切换至下一个接收波束进行测量，从而当一个time unit已经完成但还未到当前所在的OFDM符号的结束时间时，UE无需等待当前OFDM符号结束，也即无需满足一个time unit必须占用整数倍个OFDM符号这样的条件，可以占用非整数倍个OFDM符号直接进行下一个time unit的波束测量，从而可以充分利用UE的最大测量能力，在UE能力能够支持的情况下最大限度地压缩整个 波束测量的时间，有效节约时间资源，以使得更多资源可用于数据传输。
基于上述实施例，在波束对的链路质量测量之前，本公开实施例提供的方法还可以包括：
S201、接收网络侧设备发送的CSI-RS配置信息,其中，所述CSI-RS配置信息用于指示发射波束的个数、接收波束的个数以及所述符号划分信息；所述符号划分信息根据移动终端的最大划分时间分割数确定；所述最大划分时间分割数是指在满足设定条件时移动终端所支持的对OFDM符号划分的时间分割的最大个数；所述设定条件包括：在每个时间分割内，移动终端能够完成至少一次波束对的链路质量测量；所述符号划分信息为在一个OFDM符号内需要划分的时间分割的个数或时间分割的时长。
对于这里的“用于指示”、“最大划分时间分割数”以及“时间分割”的含义以及等同的概念已经在第一方面进行了说明，在此不再赘述。
相应的，步骤S202可以进一步为：
S2021、根据符号划分信息以及接收波束的个数，确定移动终端针对当前的发射波束完成一轮接收波束轮换的时刻；
也就是说，UE能够根据符号划分信息能够获知进行一次测量所需的时间，根据接收波束的个数能够获知进行一轮接收波束轮换所需的时间，从而能够获知进行一轮接收波束轮换的完成时刻。
步骤S202’可以进一步为：
S2021’、根据符号划分信息以及发射波束的个数，确定针对当前的接收波束完成一轮发射波束轮换的时刻；
也就是说，UE能够根据符号划分信息能够获知UE进行一次测量所需的时间，根据发射波束的个数能够获知进行一轮发射波束轮换所需的时间，从而能够获知进行一轮发射波束轮换的完成时刻。
在本公开实施例提供的波束测量处理方法中，UE侧在接收到CSI-RS配置信息后，根据配置信息开始波束测量。当一个time unit已经完成而还未到当前所在的OFDM符号的结束时间时，UE可以直接进行下一个time unit的波束测量，无需等待当前OFDM符号结束，也即一个time unit可以对应非整数倍个OFDM符号，从而可以充分利用UE的最大测量能力，在UE能力能够 支持的情况下最大限度地压缩整个波束测量的时间，有效节约时间资源，以使得更多资源可用于数据传输。
在具体实施时，UE侧接收到的CSI-RS配置信息可能有多种不同的情况，下面对CSI-RS配置信息可能下发的参数进行详细说明。CSI-RS配置信息可能包括下述全部或者部分内容：
(1)发射波束个数；
(2)接收波束个数；
(3)CSI-RS资源配置相关信息(Information related to CSI-RS resource configuration)，可以包括每个CSI-RS资源的CSI-RS RE pattern(CSI-RS资源元素图样)以及CSI-RS天线端口数(number of CSI-RS antenna ports)；
(4)每个CSI-RS资源所关联的时域重复次数；
(5)所用OFDM符号数；
(6)符号划分信息：可以为每个OFDM符号内划分的时间分割数(也即每个OFDM符号内可以进行的波束测量次数)，或每个时间分割的时长(也即每次波束测量的时长)；
(7)在每个OFDM符号的划分时间分割中支持的CSI-RS资源或CSI-RS端口数：
(8)CSI-RS周期：用于指示周期性波束管理的周期值等参数；
(9)波束对的链路质量测量激活信息；
(10)测量模式的指示标识；
(11)符号间隔数；
(12)CSI-RS资源个数相关信息；
(13)波束选择方式指示信息。
下面对各个参数进行说明：
对于(1)(2)，如果直接下发Tx beam个数的值和Rx beam个数的值，则UE可直接获知Tx beam个数以及Rx beam个数；这里的Tx beam个数的值可以小于等于网络侧拥有的Tx beam个数，这里的Rx beam个数可以小于等于UE拥有的Rx beam个数。也即每次波束训练时可以仅对若干个Tx beam或 Rx beam进行测量，从而能够提高波束训练的效率。
当CSI-RS配置信息下发的Rx波束的个数小于UE拥有的Rx波束的个数时，则UE可以根据预设规则选择与Rx波束的个数相同数目的Rx波束进行波束测量。假设UE一共有5个Rx波束，UE自己可以知道这五个Rx波束的逻辑编号，例如UE自己给这五个Rx波束编号为1-5。如果在上一轮波束训练中，第3个Rx波束为最优波束对链路的接收波束，若此次下发的Rx波束的个数为3，则此轮波束训练中可以以第3个Rx波束为中心，选择第2、3、4个波束进行训练，也可以等间隔的选择第1、3、5个波束进行训练。也可以有其他的选择方式，本公开实施例对此不做具体限定。当然对于实际情况中UE到底进行那种选择，那么可以有两种方式，一种是说UE预设了固定的选择模式，另一种情况是说网络侧设备可以下发参数(13)波束选择方式指示信息，从而指示UE去选择哪种模式。
对于Tx beam个数和Rx beam个数还可能存在一些特殊的情况：例如，网路侧与UE事先约定好，如果Rx beam个数为缺省状态，那么可以默认为此次要进行训练的Rx beam个数为UE所拥有的全部Rx beam个数。由于Tx beam个数和Rx beam个数与其他的配置参数还存在着一定的逻辑关系，可以通过其他配置参数能够计算出Tx beam个数和Rx beam个数，因此如果网络侧下发的配置参数中Rx beam个数为缺省状态，且网络侧设备使这个Rx beam个数为缺省的目的是为了让UE认为此次是要对所有的Rx beam进行训练，那么此时较为合理的一种情况可能是UE根据网络侧当前下发的参数无法计算Rx beam个数，此时UE就会认为当前的Rx beam个数缺省即意味着要训练全部Rx beam。
对于(3)(4)，由于波束测量的目的最终是为了让网络侧获知哪个或哪几个Tx beam为最优发射波束，而Tx beam本身不具有标识，UE通过波束测量后在波束报告中上报最优Tx beam的标识是通过上报CSI-RS资源标识或上报CSI-RS资源标识以及时间标识来实现的。具体来说，Tx beam的个数是大于或等于CSI-RS资源的个数的，也即一个CSI-RS资源可以通过一个Tx beam发射也可以通过多个Tx beam发射。当通过一个Tx beam发射时，可以直接上报CSI-RS资源标识，从而网络侧设备可以直接根据CSI-RS资源标识 来获知当时发送该CSI-RS资源时用的是哪个Tx beam；当通过多个Tx beam发射时，此时若只上报CSI-RS资源标识，网络侧可能无法获知具体是哪个Tx beam，但由于各个Tx beam的发射时间不同，因此此时同时上报时间标识即可让网络侧获知指定的Tx beam。
这里的每个CSI-RS资源的资源标识可以CSI-RS资源配置相关信息来获知，而CSI-RS资源配置相关信息包括每个CSI-RS资源的CSI-RS RE pattern以及CSI-RS天线端口数，当然还可以包括其他信息。
不难理解的是，如果配置信息中包含若干个CSI-RS资源配置相关信息，那么对于UE来说其也可以获知CSI-RS资源的总个数，相当于若干个CSI-RS资源配置相关信息隐式指示了CSI-RS资源的总个数。而CSI-RS资源的总个数A与每个CSI-RS资源所关联的时域重复次数B的乘积即为总共需要进行的波束测量次数。若设Tx beam的个数为M，Rx beam的个数为N，则有：M*N＝A*B的关系存在。等式两边的乘积均表示总共需要进行的波束测量次数。因此，那么可以根据这一等式来获得M和N的值。
当然，除了利用CSI-RS资源配置相关信息隐式指示的方式来指示CSI-RS资源的总个数，还可以通过显示指示的方式来指示。也即CSI-RS配置信息中还可以包括上述参数中的(12)CSI-RS资源个数相关信息(Information related to number of CSI-RS resource)。其中这个CSI-RS资源个数相关信息可以直接为CSI-RS资源的个数，也可以为用于指示CSI-RS资源个数的信息，本公开实施例对此不作具体限定。
对于(5)(6)，设OFDM符号个数为L，每个符号的划分时间分割个数为P，Tx beam个数为M，Rx beam个数为N，则：
如果满足L*P＝M*N，也就是说，在这L个OFDM符号内恰好完成全部收发beam sweeping。此时，对于(1)(2)(5)(6)，只需要知道其中3个参数即可，第四个参数可以推导得出。但是，等号两边的参数没有一一对应相等的关系，如L不一定等于M，P不一定等于N。因此，可以下发(1)(2)(5)(6)中的三个参数，从而UE根据这一关系来获知第四个参数。
如果L*P>M*N，则说明在L个OFDM符号内完成全部收发波束对链路质量后，还剩余若干划分时间分割。其中，L为能够满足这一关系的最小整数。 也即当M为3、N为7、P为6时，L为4。由于网路侧在配置L和P时，其是获知M、N、L、P的值，因此其在对L和P配置时肯定是根据M和N的情况进行合理的配置，尽可能的减少资源的浪费。在这样的前提下，如果网络侧此时下发的只有N(或M)、L、P的值，那么此时UE也是有可能可以根据L*P>M*N这一公式来推出M(或N)的值的。例如，N为7、P为6、L为4时，M可以为满足这个条件的最大整数，也即M＝3。当然这里说M可以为满足这个条件的最大整数只是一种可能的情况，不排除会存在使UE求得错误的M和N的个数情况。也即如果网络侧设备想让UE通过这一等式来去获取M和N中的一个，那么其必须能够确保UE根据这一关系求得的值是正确的。因此，也可以下发(1)(2)(5)(6)中的三个参数，从而UE根据这一关系可能获知第四个参数。
当L*P>M*N时，可以理解的是，这种情况下即为基站和UE配置的波束测量次数超过了整个波束训练的总次数，这样也可能会存在如图10所示的省去空闲的时间分割的情况。在这种情况下，本公开实施例提供的方法还可以在这些空闲的时间分割中携带一些其它消息，例如在采用大子载波间隔技术进行波束训练的终端，可以在剩余的时间分割内传输控制消息或者数据或者其它参考信号，从而能够将这些时间分割充分利用上，提升资源的利用率。
对于(7)，如果一个时刻仅能做单beam测量，也即单panel情况，则该参数可以省略。如果一个时刻要做多beam测量，也即多TRP或多panel情况，设在每个OFDM符号的划分时间分割中支持的CSI-RS资源(同一个CSI-RS资源内的多个CSI-RS端口使用相同的Tx beam)或CSI-RS端口数为Q，则说明同时可以进行Q个Tx beam测量。如网络侧有Q个panel，在同一时间每个panel可以产生一个Tx beam，即同时产生Q个Tx beam。
对于(8)，如果是周期性波束训练，则需要该参数。如果是周期波束训练，则根据(8)，周期性地进行Tx beam和Rx beam sweeping。
对于(9)，如果是半持续波束训练，则可以在CSI-RS配置消息中配置该参数，该参数为激活信令，激活UE进行波束训练，直至UE接收到网络侧设备下发的去激活信令为止。在这两个信令之间，进行一次或多次Tx beam和Rx beam sweeping(如果进行多次，可以周期性进行也可以非周期性进行)。
当然这一激活信令以及非激活信令也可以不配置在CSI-RS配置消息中，还可以与CSI-RS配置消息不在同一个层的信令来下发(这里的层指的是RRC层、MAC层、物理层)本公开对此不作具体限定。
此外，网络侧还可以控制UE只进行一次性的波束训练，例如，可以发送触发信令(trigger)来进行一次性的Tx beam和Rx beam sweeping。由于这样的一次训练需要很快的下发触发信令，因此一般来说可以通过物理层来下发，从而UE获知之后立刻进行一次性的波束训练。
对于(10)，可以通过显式信令或隐式通知UE。则UE在接收到指示波束扫描方式的测量模式的指示标识后，根据这一测量模式的指示标识选择进行首先做Rx波束扫描方式的测量或首先做Tx波束扫描方式的测量。
或者，该信令也可以省略，UE和网络侧可以预先约定好波束扫描的方式，例如先固定Tx beam且做Rx beam sweeping，再切换Tx beam实现Tx beam sweeping。
对于(11)，由于网络侧可以规定UE在连续的OFDM符号内进行波束训练，也可以在离散的OFDM符号内进行波束训练，当为离散的情况下，则网络侧还需下发符号间隔数，该参数可以用于指示进行波束训练的OFDM符号相隔几个符号。例如，每隔两个OFDM符号进行训练，从而UE就根据这一参数可以在进行了一个OFDM符号的训练后，在第三个符号内继续训练。
需要说明的是，CSI-RS配置参数可以通过RRC信令、MAC CE、DCI等发送给UE。
由上述叙述可以看出，根据参数之间满足的关系针对不同情况的CSI-RS配置参数，UE根据CSI-RS配置信息获知发射波束的个数、接收波束的个数也可能有多种不同的方式，下面对其中几种可选的实施方式进行说明。
一、单panel的情况，也即上述参数(7)为缺省状态。
(a)若CSI-RS配置信息包括：Tx波束的个数和Rx波束的个数；则UE直接从CSI-RS配置信息中提取得到Tx波束的个数和Rx波束的个数；
(b)若CSI-RS配置信息包括：CSI-RS资源描述信息；还包括第一波束个数；第一波束个数为Tx波束的个数或Rx波束的个数中的一种；则UE根据时域重复次数、CSI-RS资源个数相关信息以及第一波束个数计算第二波束个 数；第二波束个数为Tx波束的个数或Rx波束的个数中的另一种；也即利用上述M*N＝A*B的关系来获知Tx波束的个数以及Rx波束的个数；其中，A为CSI-RS资源个数相关信息，B为每个CSI-RS资源所关联的时域重复次数。
(c)若CSI-RS配置信息包括：CSI-RS资源描述信息，此时Rx波束的个数N为缺省状态，如果UE与网络侧事先约定好N为缺省时即意味着对所有的Rx波束进行检测，则UE将UE所拥有的Rx波束的个数作为Rx波束的个数，根据M*N＝A*B的关系计算Tx波束的个数；
(d)若CSI-RS配置信息包括：所用OFDM符号的总个数L、符号划分信息以及第一波束个数；Tx波束的个数M与Rx波束的个数N中的一个；如果符号划分信息为波束测量次数(即每个OFDM符号划分的时间分割数P)，那么直接根据L*P≥M*N这一关系来求得M和N中的另一个；如果符号划分信息为波束测量时长(即每个时间分割数的时长)，那么先根据这一时长获取每个OFDM符号划分的时间分割数P，再根据L*P≥M*N这一关系来求得M和N中的另一个。如前文中所述，根据L*P≥M*N这一关系来求得M和N中的一个有可能出现计算有偏差的时候，因为如果网络侧设备想让UE通过这样的方式来获取其中一种波束的个数，那么其就需要确保UE通过这样的方式求得的波束个数是正确的，对于下面的根据L*P≥M*N这一关系来求得M和N中的一个情况也与这一情况相同，后文中不再赘述。
(e)若CSI-RS配置信息包括：所用OFDM符号的总个数、符号划分信息；这种情况与(d)类似，但首先可以根据约定认为此时需要对所有的Rx进行测量，因此UE可以将UE所拥有的Rx波束的个数作为Rx波束的个数，再根据L*P≥M*N这一关系计算Tx波束的个数。
对于上述所述(c)与(e)的情况，需要说明的是，如果N缺省则认为此时需要对所有的Rx进行测量，那么这一内容是需要在UE与网络侧事先约定好的。如果没有约定，则不能认为N缺省就是对所有的Rx进行测量。
二、多panel的情况，也即上述参数(7)下发的情况。
(a)若CSI-RS配置信息包括：一次波束测量中支持的CSI-RS资源或CSI-RS端口数D、CSI-RS资源描述信息以及Rx波束的个数N或Tx波束的个数M；则UE此时根据一次波束测量中支持的CSI-RS资源或CSI-RS端口数D、 每个CSI-RS资源的时域重复次数B、CSI-RS资源个数相关信息A以及N或M中的一个，计算N或M中的另一个；具体来说，此时应该满足(M/D)*N＝AB；
(b)若CSI-RS配置信息包括：一次波束测量中支持的CSI-RS资源或CSI-RS端口数以及CSI-RS资源描述信息，也即N缺省的情况；则与(a)类似，UE将UE所拥有的Rx波束的个数作为Rx波束的个数，根据一次波束测量中支持的CSI-RS资源或CSI-RS端口数、时域重复次数、CSI-RS资源个数相关信息以及Rx波束的个数计算Tx波束的个数；
(c)若CSI-RS配置信息包括：一次波束测量中支持的CSI-RS资源或CSI-RS端口数、M和N之间的一个、所用OFDM符号的总个数以及符号划分信息；则UE根据符号划分信息获得波束测量次数P，再根据一次波束测量中支持的CSI-RS资源或CSI-RS端口数D、M和N之间的一个、所用OFDM符号的总个数L以及波束测量次数P，计算M和N之间的另一个。具体来说，此时应该满足L*P≥(M/D)*N；
(d)若CSI-RS配置信息包括：一次波束测量中支持的CSI-RS资源或CSI-RS端口数、所用OFDM符号的总个数以及符号划分信息，也即N缺省的情况；则与(c)类似，UE首先将UE所拥有的Rx波束的个数作为Rx波束的个数，根据一次波束测量中支持的CSI-RS资源或CSI-RS端口数、Rx波束的个数、所用OFDM符号的总个数以及符号划分信息计算Tx波束的个数。
总而言之，网络侧设备下发的CSI-RS配置信息可能针对不同的应用场景有许多不同的组合方式，网络侧设备可以根据实际需要下发最合适的配置信息组合，例如最节省信令资源的组合，UE一侧也可以根据组合的不同情况利用上述所述的参数之间的关系直接或间接的去获取测量参数完成整个测量的过程。从而这一配置参数下发以及UE与网络侧设备的模式可以多种多样，更好地适应于5G通信领域中的不同应用场景。
需要说明的是，上述一、二部分列举的几种方式仅为几种可选的实施方式，在实际应用中，本领域技术人员还可以根据各个参数之间的逻辑关系采用其他的方式来获取Tx波束的个数以及Rx波束的个数。
本公开实施例提供的波束测量处理方法中，UE一侧可以根据网络侧设备下发的配置与网路侧设备配合进行波束测量。在执行完一个time unit的测 量之后立刻进行下一个time unit的测量，从而无需满足一个time unit只能占用整数倍个OFDM符号这样的条件，可以在OFDM符号未结束之时就进入下一time unit，进而能够充分利用UE的最大能力，尽可能地压缩整个波束训练的时间，节约时间资源。同时UE一侧还可以根据下发参数的不同情况灵活的获取测量过程中的参数，还可以根据网路侧设备的指示进行不同模式的波束训练，增加了波束训练方式的多样性，从而更好地适应于5G通信领域。
