Description

一种测量方法及装置 技术领域
本申请涉及通信领域，并且具体地涉及一种测量方法与装置。
背景技术
移动业务的发展对无线通信的数据速率和效率要求越来越高。在未来无线通信系统中，波束成型技术用来将传输信号的能量限制在某个波束方向内，从而增加信号和接收的效率。波束成型技术能够有效扩大无线信号的传输范围，降低信号干扰，从而达到更高的通信效率和获取更高的网络容量。然而，在采用波束成型技术的通信网络中，首先需要将发送波束和接收波束匹配，使得发送端到接收端的增益最大，否则无法获取比较高的通信效率。而且为了达到全覆盖，要求基站端波束进行扫描。
当终端有多个波束的时候，需要使用多个半帧的同步信号/物理广播信道块(Synchronization signal/physical broadcast channel block，SS/PBCH Block)测量波束。现有技术是一个SS/PBCH块周期内只有一个半帧有SS/PBCH块，终端设备测量多个波束需要跨多个周期，因此终端设备测量波束的时间比较长。

波束在NR协议中的体现可以是空域滤波器(spatial filter)，或者称空间滤波器(spatial filter)或空间参数(spatial parameters)。用于发送信号的波束可以称为发送波束(transmission beam，Tx beam)，可以称为空间发送滤波器(spatial domain transmit filter)或空间发射参数(spatial domain transmit parameter)；用于接收信号的波束可以称为接收波束(reception beam，Rx beam)，可以称为空间接收滤波器(spatial domain receive filter)或空间接收参数(spatial domain receive parameter)。
发送波束可以是指信号经天线发射出去后在空间不同方向上形成的信号强度的分布，接收波束可以是指从天线上接收到的无线信号在空间不同方向上的信号强度分布。
应理解，上文列举的NR协议中对于波束的体现仅为示例，不应对本申请构成任何限定。本申请并不排除在未来的协议中定义其他的术语来表示相同或相似的含义的可能。
此外，波束可以是宽波束，或者窄波束，或者其他类型波束。形成波束的技术可以是波束赋形技术或者其他技术。波束赋形技术具体可以为数字波束赋形技术、模拟波束赋形技术或者混合数字/模拟波束赋形技术等。不同的波束可以认为是不同的资源。通过不同的波束可以发送相同的信息或者不同的信息。
可选地，将具有相同或者类似的通信特征的多个波束视为是一个波束。一个波束内可以包括一个或多个天线端口，用于传输数据信道、控制信道和探测信号等。形成一个波束的一个或多个天线端口也可以看作是一个天线端口集。
2、波束测量
发送端可通过波束扫描的方式发送下行信号，接收端也可通过波束扫描的方式接收下行信号。具体地，发送端可通过波束赋形的方式在空间形成不同指向性的波束，并可以在多个具有不同指向性的波束上轮询，以通过不同指向性的波束将下行信号发射出去，使得下行信号在发送波束所指向的方向上发射下行信号的功率可以达到最大。接收端也可通过波束赋形的方式在空间形成不同指向性的波束，并可以在多个具有不同指向性的波束上轮 询，以通过不同指向性的波束接收下行信号，使得该接收端接收下行信号的功率在接收波束所指向的方向上可以达到最大。
通过遍历各发送波束和接收波束，接收端可基于接收到的下行信号进行信道测量，并将测量得到的结果上报发送端。例如，接收端可以将下行信号接收功率(reference signal receiving power，RSRP)较大的部分下行信号资源上报给发送端，如上报下行信号资源的标识，以便发送端在传输数据或信令时采用信道质量较好的波束配对关系来收发信号。
下行信号可以是同步信号/物理广播信道SS/PBCH块、广播信道、广播信号解调信号、信道状态信息下行信号(channel state information reference signal，CSI-RS)、小区专用参考信号(cell specific reference signal，CS-RS)、UE专用参考信号(user equipment specific reference signal，US-RS)、下行控制信道解调参考信号，下行数据信道解调参考信号，下行相位噪声跟踪信号中任意一种。本发明实施例以SS/PBCH块为下行信号为示例进行介绍。
当前的3GPP R15对波束管理方法已标准化，简述如下：
1)配置波束管理资源。
网络设备向终端设备配置波束测量上报。波束测量上报包含以下参数的一种或多种：上报配置ID、用于波束测量的参考信号资源时频域位置、上报配置的时域行为(周期性/半静态/触发式)、上报配置的频域行为(子带/带宽等)、上报的具体内容(例如RSRP/CQI/PMI/RI/LI/CRI/SS/PBCH-ID)等。
网络设备基于波束测量上报配置，向终端设备发送波束测量信号。例如，网络设备向终端配置非零功率的信道状态信息参考信号的资源或者向终端配置SS/PBCH信号。
2)测量和选择波束，以及上报波束。
当网络设备为终端设备配置的波束测量资源内的信息位“repetition”设为OFF时，终端设备被告知网络设备发送不同的发送波束，这种情形下，终端设备需要基于波束测量上报配置的上报行为，上报发送波束的测量信息。
例如，终端设备基于波束测量上报配置，在相应的时频域位置接收测量信号。
终端设备基于特定的准则，从网络设备下发的发送波束中选择N(N为大于1的整数)个发送波束，并上报这N个波束对应的资源ID(在3GPP中，资源ID可以是CSI-RS resource index，也可以是SS/PBCH index)和信号接收功率给该网络设备。
终端设备上报波束的选取准则可以是网络设备指定的，也可以是终端设备的内部实现算法。例如，终端设备可以从配置的用于波束管理的非零功率的CSI-RS的资源集合中选择波束质量最好的前几个波束进行上报。
3、SS/PBCH块周期
NR对于SS/PBCH块周期的定义可以理解为：
对于每个服务小区中SS/PBCH块的接收，终端在每个服务小区通过高层参数ssb-periodicityServingCell每半帧周期性地被配置，对于该中文的理解也可以参考下列英文：A Terminal can be provided per serving cell by higher layer parameter ssb-periodicityServingCell a periodicity of the half frames for reception of the SS/PBCH blocks for the serving cell。
4、SS/PBCH块
一个半帧中包含一个SS/PBCH块，该SS/PBCH块在半帧中的位置与系统的子载波间隔有关。本发明中的SS/PBCH块包含主同步信号(Primary Synchronization Signal，PSS)，辅同步信号(Secondary Synchronization Signal，SSS)，和物理广播信道PBCH信号当中的至少一种。
一个半帧的长度为5ms，不同的子载波间隔下，半帧包含不同的时隙数目，一个时隙包括14个OFDM符号。其中，SS/PBCH块在半帧中占用4个OFDM符号，第一个符号位主同步信号(Primary Synchronization Signal，PSS)，第二个符号位PBCH，第三个符号位PBCH和辅同步信号(Secondery Synchronization Signal，SSS)，第四个符号位PBCH，其中PBCH符号上包含有PBCH的解调参考信号(De-Modulation Reference Signal，DMRS)。
在现有的NR协议中，SS/PBCH块在半帧内的位置是确定的，目前SS/PBCH块在半帧内的时域位置有5中模式(pattern)，分别是patternA、pattern B、patternC、pattern D、pattern E。其中，pattern A主要针对子载波间隔为15kHz的情况，pattern B和pattern C主要针对是子载波间隔为30kHz的情况，pattern D和pattern E主要针对的是120kHz和240kHz的情况。
例如，对于pattern A，SS/PBCH块在半帧中的时域位置满足以下公式：
SS/PBCH块的第1个OFDM符号索引为{2,8}+14*n。对于载波频率小于等于3GHz，有n＝0,1。对于载波频率大于3GHz且小于6GHz，有n＝0,1,2,3。
对于pattern B，SS/PBCH块在半帧中的时域位置满足以下公式：
SS/PBCH块的第1个OFDM符号索引为{4,8,16,20}+28*n。对于载波频率小于等于3GHz，有n＝0。对于载波频率大于3GHz且小于6GHz，有n＝0,1。
对于patternC，SS/PBCH块在半帧中的时域位置满足以下公式：
SS/PBCH块的第1个OFDM符号索引为{2,8}+14*n。对于载波频率或工作频率小于3GHz的时候，n为0,1；当载波频率或工作频率大于3GHz小于6GHz的时候，n的值为0,1,2,3。
对于pattern D，SS/PBCH块在半帧中的时域位置满足以下公式：
SS/PBCH块的第1个OFDM符号索引为{4,8,16,20}+28*n，当载波频率或工作频率大于6GHz的时候，n的值为0,1,2,3,5,6,7,8,10,11,12,13,15,16,17,18。
对于pattern E，SS/PBCH块在半帧中的时域位置满足以下公式：
SS/PBCH块的第1个OFDM符号索引为{8,12,16,20,32,36,40,44}+56*n，当载波频率或工作频率大于6GHz的时候，n的值为0,1,2,3,5,6,7,8。
以上为本申请相关术语和知识的介绍，下面开始介绍本发明的具体实施方式。
本申请实施例可以应用于基于波束的多载波通信系统，例如，5G系统或新无线(new radio，NR)系统。
图1为本申请实施例的通信系统100的示意图。该通信系统100包括一个网络设备110与多个终端设备120(如图1中所示的终端设备120a和终端设备120b)。网络设备110可以通过多个射频通道同时发送多个模拟波束来为多个终端设备传输数据。如图1所示，网络设备发送波束1和波束2，其中波束1用于为终端设备120a传输数据，波束2用于为终端设备120b传输数据。波束1可以称为终端设备120a的发送波束，波束2可以称为终端设备120b的发送波束。
网络设备101可以为基站，基站可以用于与一个或多个终端进行通信，也可以用于与一个或多个具有部分终端功能的基站进行通信(比如宏基站与微基站，如接入点，之间的通 信)。基站可以是时分同步码分多址(Time Division Synchronous Code Division Multiple Access，TD-SCDMA)系统中的基站收发台(Base Transceiver Station，BTS)，也可以是LTE系统中的演进型基站(Evolutional Node B，eNB)，以及5G系统、新空口(NR)系统中的基站。另外，基站也可以为接入点(Access Point，AP)、传输节点(Trans TRP)、中心单元(Central Unit，CU)或其他网络实体，并且可以包括以上网络实体的功能中的一些或所有功能。
终端设备可以指用户设备(user equipment，UE)、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。终端设备还可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，5G网络中的终端设备或者未来演进的公用陆地移动通信网络(public land mobile network，PLMN)中的终端设备等。
根据现有的新空口(New Radio，NR)标准规定一个SS/PBCH块周期内SS/PBCH块的最大数目在低频为4个或8个，在高频最大数目为64个。终端设备接收SS/PBCH块时处于空闲态(idle)，接收寻呼消息(paging)也是在空闲态，寻呼消息和SS/PBCH块的发送波束可以是相同的波束，即SS/PBCH块与寻呼消息具有准共址(quasi-co-location)关系。终端设备在接收寻呼消息之前提前醒来，需要测量波束，测量波束可以采用SS/PBCH block信号。但当前NR协议规定一个SS/PBCH块周期内只有一个半帧有SS/PBCH块信号，如果测量多个波束，需要跨多个SS/PBCH块周期，导致波束测量的时间比较长。
如图2所示，假设SS/PBCH块的周期为10ms，半帧的长度为5ms，每一个SS/PBCH块周期只有一个半帧有SS/PBCH块，如果发送端通过SS/PBCH块发送了2个波束，终端需要测量这两个波束，那么需要20ms的时间才能完成波束接收。
如图3所示，假设SS/PBCH块的周期为40ms，网络设备发送了4个波束，终端需要对这四个波束进行测量，一个周期只有一个半帧包括SS/PBCH块，如果需要完成4个波束测量，那么需要160ms的时间。
本申请针对上述问题，提出一种测量的方法与装置，可以使得波束测量的时间相比现有技术更短。
本发明实施例提供一种测量的方法，可以降低测量的时间。
图4为本申请实施例提供的测量方法400的示意性交互流程图。该方法400包括：
S410，在一个SS/PBCH块周期T内，网络设备发送多个半帧至终端，所述多个半帧中至少有两个半帧内包括有SS/PBCH块；
S420，终端设备接收所述多个半帧，并测量所述SS/PBCH块的信号强度。
本申请提供的实施例与现有技术相比，可以降低波束测量的时间，节省终端设备的开销。
应理解，终端测量波束可以是所有的SS/PBCH块对应的波束，也可以是部分SS/PBCH块对应的波束。
可选地，所述方法400还包括：网络设备采用所述SS/PBCH块对应的波束发送消息。比如，采用所述SS/PBCH块对应的波束发送寻呼消息。
如图5所示，假设SS/PBCH块的周期为10ms，半帧的长度为5ms，每一个SS/PBCH块周期有2个半帧有SS/PBCH块，如果网络设备通过SS/PBCH块发送了2个波束，终端只需要10ms的时间就可以完成波束接收与测量。
以SS/PBCH块周期为20ms，终端设备通过SS/PBCH块测量4个波束为例，现有技术需要40ms才能完成波束测量；采用本发明实施例提供的方案，只需要不到20ms就可以完成波束测量。
如图6所示，本申请提供的方案，假设SS/PBCH块的周期为40ms，网络设备发送4个波束，终端需使用这四个波束进行对SS/PBCH块进行接收和测量，在一个SS/PBCH块周期内配置了4个包含SS/PBCH块的半帧，使得终端可以使用20ms的时间就可以完成对波束的测量，节省了140ms的时间，大大地降低了开销。
该SS/PBCH块的周期的取值可以通过高层信令发送，比如，通过高层信令的参数ssb-periodicityServingCell发送。
在一种实现方式中，所述多个半帧内的第二半帧的SS/PBCH块相对于所述多个半帧内的第一半帧的SS/PBCH块的具有时间偏移X，X的单位可以是毫秒，半帧，子帧，时隙，OFDM符号。
在另一种实现方式中，可以以SS/PBCH块周期的起始位置为参考点，所述多个半帧中的第一半帧的SS/PBCH块相对于该参考点具有时间偏移X，X的单位可以是毫秒，半帧，子帧，时隙，OFDM符号。
例如，当时间偏移值单位为毫秒时，可以发送具体的取值，也可以发送用于指示具体值的一个索引。
示例性地，假设SS/PBCH块周期T为30ms，半帧的时间长度为5ms，一个周期T内具有6个半帧，其中，该6个半帧中包含3个SS/PBCH块。如图7所示，
第一个SS/PBCH块位于第1个半帧中；
第二个SS/PBCH块位于第3个半帧中；
第三个SS/PBCH块位于第5个半帧中。
第一个SS/PBCH块与第二个SS/PBCH块之间的时间长度为偏移值offset，比如，如图7所示，offset取值为10ms，或者offset取值为2个半帧。
在一个SS/PBCH周期内，偏移值可以相同，也可以不同。
可选地，网络设备配置所述偏移值时，也可以配置其中一个SS/PBCH块在SS/PBCH周期内的时间位置，再配置各个SS/PBCH块相对于该SS/PBCH块的offset。
例如，可以配置第一个SS/PBCH所在半帧的位置值或者配置最后一个SS/PBCH所在半帧的时间位置，再配置其他剩余的SS/PBCH块所在半帧相对于第一个SS/PBCH块所在半帧的时间偏移或者相对于最后一个SS/PBCH块所在半帧的时间偏移。
可选地，网络设备配置所述偏移值时，也可以选定SS/PBCH块周期内的某一固定位置为偏移值的参考点，例如将周期的起始位置(周期内第一个帧的第一个时隙)配置为参考点，再配置各个SS/PBCH块所在半帧相对于该参考点的时间偏移。
所述时间偏移offset的值可以为正，也可以为负。
不同的SS/PBCH块周期长度，上述偏移值也可以不同。
比如，SS/PBCH块的周期为20ms，则在SS/PBCH块周期内可以配置的、包含SS/PBCH块的 半帧数目为1、2或3。可以配置的offset为5ms，10ms，或者15ms。
再比如，SS/PBCH块的周期为40ms，则SS/PBCH块在SS/PBCH块周期内的半帧数目可以为1,2,3,4,5,6,7全部或部分。SS/PBCH块所在的半帧在SSB周期内的具体的位置值或SS/PBCH块的相对时间偏移值offset可以为5,10,15,20,25,30,35部分或者全部；单位为ms；如果单位为半帧，offset的取值为1,2,3,4,5,6,7中的部分或全部。
再比如，SS/PBCH块的周期为80ms，则SS/PBCH块在SS/PBCH块周期内的半帧数目可以为1,2,3,4,5,6,7,8,9,10,11,12,13,14,15全部或部分。SS/PBCH块所在的半帧在SSB周期内的具体的位置值或SS/PBCH块的相对时间偏移值offset可以为0,5,10,15，20,25,30,35,40,45,50,55,60,65,70,75部分或者全部，单位为ms；如果单位为半帧，offset的取值为1-15中的部分或全部。
再比如，SS/PBCH块的周期为160ms，则SS/PBCH块在SS/PBCH块周期内的半帧数目可以为1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31全部或部分，SS/PBCH块所在的半帧在SSB周期内的具体的位置值或SS/PBCH块的相对时间偏移值offset可以为5,10,15，20,25,30,35,40,45,50,55,60,65,70,75，80，85，90，95，100，105，110，115，120，125，130,135,140,145,150,155的部分或全部，单位为ms；如果单位为半帧，offset的取值为1-31中的部分或全部。
本申请提供的方案，在一个SS/PBCH块的周期T内发送多个半帧，其中，多个半帧包含有SS/PBCH块(一个半帧上只有一个SS/PBCH块)，终端设备在一个周期内可以对多个SS/PBCH块进行测量，节省波束测量的时间，提升了效率。
在另一个实施例中，本申请的技术方案原理还可以应用在基于SS/PBCH块的无线资源管理测量时间配置(SS/PBCH block based RRM measurement timing configuration,SMTC)中，具体的应用如下：
步骤1：在一个SS/PBCH块的周期内，网络设备配置多个SMTC，该多个SMTC中至少两个SMTC包括有SS/PBCH块，其中，一个SMTC中包含一个SS/PBCH块；
步骤2：终端测量收到的SS/PBCH块的信号强度应理解，终端测量波束可以是所有的SS/PBCH块对应的波束，也可以是部分SS/PBCH块对应的波束。
对于SMTC来说，在一个SS/PBCH块周期内，SS/PBCH的时间偏移的描述可以直接参考上面实施例的描述，这里不再赘述。
可以理解的是，上述各个方法实施例中，由终端设备实现的方法和操作，也可以由可用于终端设备的部件(例如芯片或者电路)实现，由网络设备实现的方法和操作，也可以由可用于网络设备的部件(例如芯片或者电路)实现。

本申请实施例可以根据上述方法示例对发射端设备或者接收端设备进行功能模块的划分，例如，可以对应各个功能划分各个功能模块，也可以将两个或两个以上的功能集成在一个处理模块中。上述集成的模块既可以采用硬件的形式实现，也可以采用软件功能模块的形式实现。需要说明的是，本申请实施例中对模块的划分是示意性的，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式。下面以采用对应各个功能划分各个功能模块为例进行说明。

接收单元810，用于接收多个半帧，所述多个半帧中至少有两个半帧内包括有SS/PBCH块；或者，用于接收多个SMTC，所述多个SMTC中至少有两个SMTC中包括有SS/PBCH块；
处理单元820，用于测量所述SS/PBCH块的信号强度。
应理解，终端设备测量的波束可以是所有SS/PBCH块对应的波束，也可以是部分SS/PBCH块对应的波束，本发明对此不予限定。
因此，本申请提供的方案，通过在多个半帧中发送SS/PBCH块，可以减少波束测量的时间，节省终端设备的开销。
可选地，所述接收单元810，还用于接收来自网络设备的SS/PBCH块的周期的指示信息。该SS/PBCH块的周期T的取值可以通过高层信令接收，比如，通过高层信令的参数ssb-periodicityServingCell接收。

处理单元910，用于生成多个半帧，所述多个半帧中至少两个半帧包括SS/PBCH块；或者，生成多个SMTC，所述多个SMTC中至少有两个SMTC包括SS/PBCH块；
发送单元920，用于在一个SS/PBCH块周期内，向终端设备发送所述多个半帧或所述多个SMTC。
可选地，所述发送单元920，还用于采用所述SS/PBCH块对应的波束发送寻呼消息。
应理解，网络设备可以选择部分SS/PBCH块对应的波束发送寻呼消息，也可以选择全部的SS/PBCH块对应的波束发送寻呼消息，本发明不予限定。
因此，本申请提供的方案，通过在一个SS/PBCH块周期内发送多个半帧，多个半帧中至少两个半帧中包括有SS/PBCH块，大大减少了波束测量的时间。
