Description

发送和接收指示的方法和装置
本申请要求于2019年1月31日提交中国国家知识产权局、申请号为201910098040.7、发明名称为“发送和接收指示的方法和装置”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
本申请涉及无线通信领域，并且更具体地，涉及发送和接收指示的方法以及装置。
背景技术
移动通信的迅速发展对小区边缘用户的性能提出了更高要求，在通信系统中，随着移动通信的快速发展，在系统容量，瞬时峰值速率，频谱效率，小区边缘用户吞吐量以及时延等诸多方面有了更高的要求。协同多点(Coordination Multiple Point，CoMP)传输技术无论是在上行还是下行，都可以提高系统性能，是一种用于解决小区间干扰问题并提升小区边缘用户吞吐量的方法，尤其是改善小区边缘的频谱效率。
协同多点技术包括了协同波束成型(coordinated beamforming)、协同调度(coordinated scheduling)、联合传输(joint transmission)、动态传输点选择(dynamic point selection)、动态传输点静默(dynamic point blanking)等技术。基站或者TRP之间可以通过回程、空口等途径进行交互，协调传输所需要的信息。通过这些传输方法，可以降低对边缘用户的干扰，提高系统的性能。
在CoMP技术中，可能同时有多个传输接收点(multi-transmitting and receiving point，multi-TRP)服务同一个终端设备。在multi-TRP协作时，为了达到联合传输的性能，需要多个站点同步传输，但在实际传输过程中，TRP之间的同步实际实现起来有较大的复杂度，如果一味假设多个站点之间传输同步，会影响信道估计和协同传输的性能。如何准确获知同步状态以保障协同传输的性能，是个亟需解决的问题。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
本申请实施例的技术方案可以应用于各种通信系统，例如：LTE时分双工(time division duplex，TDD)、通用移动通信系统(universal mobile telecommunication system，UMTS)、全球互联微波接入(worldwide interoperability for microwave access，WiMAX)通信系统、第五代(5th generation，5G)系统或新无线(new radio，NR)等。
应理解，该通信系统中的网络设备可以是任意一种具有无线收发功能的设备或可设置于该设备的芯片，该设备包括但不限于：演进型节点B(evolved Node B，eNB)、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)，无线保真(Wireless Fidelity，WIFI)系统中的接入点(Access Point，AP)、无线中继节点、无线回传节点、传输点(transmission point，TP)或者发送接收点(TRP)等，还可以为5G，如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)等。
在一些部署中，gNB可以包括集中式单元(centralized unit，CU)和DU。gNB还可以包括射频单元(radio unit，RU)。CU实现gNB的部分功能，DU实现gNB的部分功能，比如，CU实现无线资源控制(radio resource control，RRC)，分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能，DU实现无线链路控制(radio link control，RLC)、媒体接入控制(media access control，MAC)和物理(physical，PHY)层的功能。由于RRC层的信息最终会变成PHY层的信息，或者，由PHY层的信息转变而来，因而，在这种架构下，高层信令，如RRC层信令或PHCP层信令，也可以认为是由DU发送的，或者，由DU+RU发送的。可以理解的是，网络设备可以为CU节点、或DU节点、或包括CU节点和DU节点的设备。此外，CU可以划分为接入网RAN中的网络设备，也可以将CU划分为核心网CN中的网络设备，在此不做限制。
还应理解，该通信系统中的终端设备也可以称为用户设备(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。本申请的实施例中的终端设备可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(Virtual Reality，VR)终端设备、增强现实(Augmented Reality，AR)终端设备、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)中的无线终端等等。本申请的实施例对应用场景不做限定。
为便于理解本申请实施例，首先对本申请中涉及的几个术语做简单说明。
1、同步测量：针对同步传输的多个信号进行的测量。其中，所谓的同步传输，是从接收端角度进行描述，指多个信号到达接收端是同步的，即接收端理论上应该能够同时(在同一段时间内)接收同步传输的信号。
同步测量包括测量多个关联同步测量的信号的到达时间，确定多个到达时间之间的偏差，比如，测量基准参考信号的到达时间，并且测量比对参考信号的到达时间相对于基准参考信号的偏差；或者是以基准参考信号的到达时间为起点时间，确定比对参考信号的接收相对于所述起点时间经过了多长的时间。或者是，测量多个关联同步测量的信号之间的相位变化，相位变化可以是基于信号之间的相位信息的差别得到的，所述相位信息可以是指信号或者是测量出的信道在一个或者多个频域单元上的差值；信号的相位信息至少包括相位的斜率信息，所述斜率信息是指信号以子载波的波形为变化的斜率信息。所述的偏差、差别等可以体现为差值、比值等形式。其中，频域单元可以是子载波、资源块(resource block，RB)、子带(subband)等。
同步测量还可以被称为时延测量，相位测量，相位斜率测量，或相位变化测量等。
需要说明的，上述关联同步测量的信号(即同步传输所传输的同步信号)并非实际上一定能够同时被接收端接收，同步测量是为了保证假设的同步传输而进行的测量，以确定信号传输是否真正同步。以上测量到达时间的偏差、信号之间的相位信息的差别，仅是示例的同步测量的手段，其均不构成对本申请实施例的特别限定。
同时的概念包括在同一段时间内、或在同一采样点，或在同一采样点集合、或在同一符号(symbol)，或在同一符号集合(如，同一时隙、同一帧等)等。
可以理解，同步测量所针对的对象，可以是具体的传输对象，即参考信号，也可以用传输信号的天线端口来表征。
2、参考信号与参考信号资源：参考信号可用于信道测量、信道估计或者波束质量监测等。参考信号资源关联参考信号的配置信息，例如，时频资源位置、端口映射关系、功率因子、预编码信息、时延信息、相位偏移信息以及扰码等，具体可参考现有技术。发送端设备可基于参考信号资源的配置信息发送参考信号，接收端设备可基于参考信号资源的配置信息接收参考信号。参考信号资源可以用参考信号资源标识来标记。
具体地，本申请实施例中涉及的参考信号例如可以包括信道状态信息参考信号(channel state information reference signal，CSI-RS)、同步信号块(synchronization signal block，SSB)、解调参考信号(demodulation reference signal，DMRS)、相位跟踪信号(Phase tracking reference signal，PTRS)以及探测参考信号(sounding reference signal，SRS)。与此对应地，参考信号资源可以包括CSI-RS资源(CSI-RS resource)、SSB资源、SRS资源(SRS resource)、PTRS资源等。
需要说明的是，上述SSB也可以称为同步信号/物理广播信道块(synchronization signal/physical broadcast channel block，SS/PBCH block)，所对应的SSB资源也可以称为同步信号/物理广播信道块资源(SS/PBCH block resource)，可简称为SSB resource。在 某些情况下，SSB也可以是指SSB资源。在本申请实施例中，为便于区分和说明，在未作出特别说明的情况下，SSB可以视为SS/PBCH block，SSB资源可以视为SS/PBCH block resource。
为了区分不同的参考信号资源，每个参考信号资源可对应于一个参考信号资源的标识，例如，CSI-RS资源标识(CSI-RS resource indicator，CRI)、SSB资源标识(SSB resource indicator，SSBRI)、SRS资源索引(SRS resource index，SRI)、物理随机接入信道(Physical Random Access Channel，PRACH)上传输的前导序列的资源标识。
其中，SSB资源标识也可以称为SSB标识(例如，SSB index)。
应理解，上文中列举的参考信号以及相应的参考信号资源仅为示例性说明，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参考信号来实现相同或相似功能的可能。
在一种可能的设计中，网络设备可通过无线资源控制(Radio Resource Control，RRC)消息向终端设备发送CSI资源配置(CSI resource setting)，每个CSI resource setting可以包括S(S≥1，且S为整数)个CSI-RS资源集(CSI-RS resource sets)，每个CSI-RS resource set可包括K(K≥1，且K为整数)个非零功率(Non-Zero Power，NZP)CSI-RS资源(NZP CSI-RS resources)。终端设备可以根据网络设备所指示的K个NZP CSI-RS resources接收CSI-RS。
在另一种可能的设计中，终端设备在接入小区时，便可以获知SSB的资源配置信息。网络设备也可以通过一种特殊的CSI-RS资源集指示一个或多个SSB资源的标识，该SSB资源例如可以是信道状态信息同步信号块资源集(CSI-SSB-Resource Set)。
应理解，上文列举的网络设备向终端设备指示参考信号资源的具体方法仅为示例，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采用其他的信令或方式指示参考信号资源的可能。例如，网络设备可进一步通过下行控制信息(downlink control information，DCI)指示K个NZP CSI-RS resources中使用的J(K≥J≥1，且J为整数)个NZP CSI-RS resources。
3、天线端口(antenna port)：简称端口。被接收端设备所识别的发射天线，或者在空间上可以区分的发射天线。天线端口是一种逻辑上的含义，针对每个虚拟天线可以配置一个天线端口，每个虚拟天线可以为多个物理天线的加权组合，每个天线端口可以与一个参考信号端口对应。天线端口用于承载具体的物理信道和物理信号中至少一种。通过相同天线端口所发送的信号，无论这些信号是否是通过相同或不同的物理天线发送，他们在空间传输所经历的路径所对应的信道可视为相同或者相关(比如大尺度信道特性，如信道矩阵H，相同)。也就是说，在相同的天线端口所发送的信号，接收端在解调时可以认为其信道相同或者相关。也就是说，天线端口定义了在某个符号上的信道，两个符号的天线端口一样是说在一个符号上的信道可以通过另一个符号上的信道推知。
4、准共址(quasi-co-location，QCL)：QCL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。例如，如果两个天线端口具有准共址关系，那么一个端口传送一个信号的信道大尺度特性可以从另一个端口传送一个信号的信道大尺度特性推断出来。具有QCL关系的天线端口对应的信号中具有相同的参数，或者，一个天线端口的参数可用于确定与该天线端口具有QCL关系的另一个天线端口的参数，或者，两个天线端口具有相同的参数，或者，两个天线端口间的参数差小于某阈值。其中，所述参 数可以包括以下一项或多项信道大尺度参数：时延扩展(delay spread)，多普勒扩展(Doppler spread)，多普勒频移(Doppler shift)，平均时延(average delay)，平均增益，或空间接收参数(spatial Rx parameters)等。其中，空间接收参数可以包括发射角(Angle of departure，AOD)、主发射角(Dominant AoD)、平均到达角(Average AoA)、到达角(Angle of arrival，AOA)、信道相关矩阵，到达角的功率角度扩展谱，平均发射角(Average AoD)、出发角的功率角度扩展谱、发射信道相关性、接收信道相关性、发射波束成型、接收波束成型、空间信道相关性、空间滤波器，空间滤波参数，或空间接收参数等中的一项或多项。
在现有NR协议中，上述具有QCL关系可以基于不同的参数分为以下四种类型：
类型A(type A)：多普勒频移、多普勒扩展、平均时延、时延扩展；
类型B(type B)：多普勒频移、多普勒扩展；
类型C(type C)：多普勒频移、平均时延；以及
类型D(type D)：空间接收参数。
本申请实施例所涉及关联同步测量的QCL关系，可以复用现有的类型，也可以新增新的类型定义，例如类型E的QCL，即，关于平均时延(average delay)，时延扩展(delay spread)中至少一种接收参数定义的QCL。该示例仅为例举，不构成对本申请的限制。
当QCL关系指类型对应关联同步测量(假设类型E)的QCL关系时：第一信号和第二信号之间之间的QCL关系，或第一天线端口和第二天线端口之间的QCL关系，可以是指两个信号(或两个天线端口)假设具有相同或相近的的平均时延和时延扩展中至少一种，也就是其中之一(信号/天线端口)的平均时延和时延扩展中至少一种可以用于推知另一个(信号/天线端口)的平均时延和时延扩展中至少一种，即所述QCL关系用于表示两个信号(或两个天线端口)同步传输。
5、传输配置指示(transmission configuration indicator，TCI)：可用于指示两种参考信号之间的QCL关系。网络设备可通过高层信令(如无线资源控制(radio resource control，RRC)消息)为终端设备配置至少一个TCI状态(TCI state)，并可以通过高层信令(如媒体接入控制-控制元素MAC CE)或物理层信令(如下行控制信息DCI)中至少一种，激活或指示其中的一个或多个TCI状态。具体地，网络设备可通过RRC消息为终端设备配置TCI状态列表，终端设备在接收来自网络设备的物理下行控制信道(physical downlink control channel，PDCCH)时，可以根据MAC CE的至少一个指示激活控制信道TCI状态中的一个或多个，其中控制信道TCI状态为RRC配置的至少一个TCI状态的子集；终端设备可以从PDCCH中获取DCI，根据DCI的指示选择至少一个数据信道TCI状态中的一个或多个TCI状态，其中所述至少一个数据信道TCI状态为RRC配置的至少一个TCI状态的子集，通过MAC-CE信令指示给终端设备。应注意，本申请中子集的概念还包括全集和空集。
一个TCI状态的配置信息可以包括一个或多个参考信号资源的标识，以及所关联的至少一个QCL类型。当QCL关系配置为类型A、或B、或C中的一种时，终端设备可以根据TCI状态的指示，解调物理下行控制信道(Physical Downlink Control Channel，PDCCH)或物理下行共享信道(Physical Downlink Shared Channel，PDSCH)。
TCI状态还可以用于指示CSI-RS资源的接收。如为某CSI-RS资源(组)配置TCI状态，则UE根据TCI状态中的参考信号资源、关联的QCL类型，来接收CSI-RS。
当QCL关系配置为对应关联同步测量(假设类型E)的类型时，终端设备可以知道对哪些下行信号或者天线端口假设同步传输，进行同步测量。
6、波束：波束在NR协议中的体现可以是空域滤波器(spatial filter)，或者称空间滤波器或空间参数(spatial parameters)。用于发送信号的波束可以称为发射波束(transmission beam，Tx beam)，也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)，也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)。
发射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。
7、信道状态信息(channel state information，CSI)：可以包括以下至少一项信息：信道质量指示(channel quality indicator，CQI)，预编码矩阵指示(precoding matrix indicator，PMI)，CSI-RS资源指示(CSI-RS resource indicator)，同步信号块(SSB)资源指示(SS/PBCH block resource indicator，SSBRI)，层指示(layer indicator，LI)，秩指示(rank indicator，RI)，参考信号接收功率(reference signal received power，RSRP)。RSRP可以是层1的RSRP(L1-RSRP)。在本申请中，信道状态信息还可以包括同步测量结果或同步测量结果的指示信息。
此外，为了便于理解本申请实施例，作出以下几点说明。
第一，在下文示出的实施例中第一、第二以及各种数字编号仅为描述方便进行的区分，并不用来限制本申请实施例的范围。例如，第一、第二在本申请实施例中可以作为类型区分，并不作为对象内容区分：第一参考信号和第二参考信号，这两类参考信号关联同步测量，一类为基准信号，一类为比对信号，但并不是限制“至少一个第一参考信号”一定是同一TRP或同一天线端口发出的，也并不是限定其传输内容相同。
第二，本申请实施例中涉及的“保存”，可以是指保存在一个或者多个存储器中。所述一个或者多个存储器，可以是单独的设置，也可以是集成在编码器或者译码器，处理器、或通信装置中。所述一个或者多个存储器，也可以是一部分单独设置，一部分集成在译码器、处理器、或通信装置中。存储器的类型可以是任意形式的存储介质，本申请并不对此限定。
第三，本申请实施例中涉及的“协议”可以是指通信领域的标准协议，例如可以包括LTE协议、NR协议、WLAN协议以及其他通信系统中的相关协议，本申请对此不做限定。
第四，“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B的情况，其中A，B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项(个)”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a、b和c中的至少一项(个)，可以表示：a，或，b，或，c，或，a和b，或，a和c，或，b和c，或，a、b和c。其中a、b和c分别可以是单个，也可以是多个。
第五，本申请实施例中“基准参考信号”、“基准天线端口组”、“基准点”、“锚点参考信号”均是描述一对象作为其他对象的参照比对的基础，“比对参考信号”、“比 对天线端口组”均是描述一对象参考基准对象去进行比对，比对相对于基准对象的偏差。
为便于理解本申请实施例，下面以图1示出的通信系统为例详细说明适用于本申请实施例提供的发送和接收指示的方法的通信系统。如图1所示，该通信系统100可以包括至少一个终端设备101；该通信系统100还可以包括至少一个网络设备，如图1中所示的网络设备#1 102或网络设备#2 103。
可选地，该网络设备#1 102和网络设备#2 103可以是同一个小区中的网络设备，也可以是不同小区中的网络设备，本申请对此不作限定。图1中仅为示例，示出了网络设备#1 102和网络设备#2 103位于同一个小区中的示例。
在通信系统100中，网络设备#1 102和网络设备#2 103彼此之间可通过回程(backhaul)链路通信，该回程链路可以是有线回程链路(例如光纤、铜缆)，也可以是无线回程链路(例如微波)。网络设备#1 102和网络设备#2 103可以进行相互协同，来为终端设备101提供服务。因此，终端设备101可通过无线链路分别与网络设备#1 102和网络设备#2 103通信。
此外，网络设备#1 102和网络设备#2 103中的一个或多个还可以分别采用载波聚合技术，在一个或多个载波分量(component carrier，CC)上为终端设备101调度PDSCH。例如，网络设备#1 102可以在CC#1和CC#2上为终端设备101调度PDSCH，网络设备#2 103可以在CC#1和CC#3上为终端设备101调度PDSCH。网络设备#1 102和网络设备#2 103所调度的CC可以是相同的，也可以是不同的，本申请对此不作限定。
相互协同的网络设备之间的通信时延可以分为理想回程(ideal backhaul)和非理想回程(non-ideal backhaul)。理想回程下的两站点之间，通信时延可以是微秒级别，与NR中毫秒级别的调度相比，可以忽略不计；非理想回程下的两站点之间，通信时延可以是毫秒级别，与NR中毫秒级别的调度相比，无法忽略。
为了保证协同传输的性能，对网络设备之间的同步精度有要求。但是由于网络设备的精准同步要求消耗成本过高从而只能达到精准要求范围以外的同步、终端设备到网络设备的位置的随机性，多个网络设备给一个终端进行协同传输时，多个网络设备的信号到终端设备的传播时延可能会不一样。所以在实际传输过程中，网络设备之间的同步实际实现起来有较大的复杂度，同步的状态会影响信道估计和协同传输的性能。如协同传输中，如果终端收到来自多个网络设备的信号是没有在时域上对齐的，则系统可能会引入额外的干扰。
举例而言，根据部署的位置和协商，图1的网络设备#1 102和网络设备#2 103为终端设备101提供协同传输。在实际传输中，由于终端设备101的移动，和传播路径中障碍物的遮挡等，网络设备到终端设备的实际传输时延和理论传输时延可能会有偏差，理论同步在实际上可能出现同步偏差。图1中，网络设备#1 102到终端设备101的实际传输时延为t1，网络设备#2 103到终端设备101的实际传输时延为t2，终端设备101假设网络设备#1 102和网络设备#2 103是同步传输的，也就是说，假设网络设备#1 102和网络设备#2 103传输的信号到达终端设备101的时间一样，或者满足设定的时间差。而实际上t1和t2并不满足假设的需求，那么终端设备101进行信道估计就会出现偏差，同时协同传输的性能也得不到保障。
有鉴于此，本申请提供一种发送和接收指示的方法，以保障协同传输的性能。
下面结合附图详细说明本申请实施例提供的发送和接收数据的方法。
图2是从设备交互的角度示出的本申请实施例提供的发送和接收指示的方法200的示意性流程图。需要说明的是，本实施例及后续实施例皆以终端设备与网络设备之间交互为例进行描述。为了便于方案理解，在描述时，本实施例及后续实施例皆以终端设备和网络设备多侧的行为展开，从交互多方的角度进行整体描述，但绝非限定系统中改进在于交互各侧的步骤必须合在一起执行，本申请提出的技术方案，在系统中每一侧均有改进。
需要说明的是，本申请提供的发送和接收指示的方法可以应用于无线通信系统中，例如，图1中所示的通信系统100中。处于通信系统中的通信装置之间可具有无线通信连接关系。例如，图1中所示的终端设备101分别可以与网络设备#1 102和网络设备#2 103之间具有无线通信连接关系。网络设备#1 102和网络设备#2 103之间可以是理想回程链路，也可以是非理想回程链路，本申请对此不作限定。图1所示的仅是本申请所涉及的一种网络系统架构的示例，本申请并不局限于此。应理解，图1所示的本申请实施例可适用的协同传输场景，可以是同构网络的协同传输场景，也可以是异构网的协同传输场景，本申请实施例并不对此做限定。还应理解，图1所示的场景可以是低频(如中心频率在6G赫兹以下)场景，也可以是高频(如中心频率在6G赫兹以上)场景，本申请实施例并不对此做限定。
如图2所示，本申请实施例的方法200可以包括步骤210至步骤230。下面详细说明方法200中的各步骤：
在步骤210中，网络设备生成第一指示信息，所述第一指示信息用于指示至少一个第一参考信号和至少一个第二参考信号关联同步测量。
参考信号关联同步测量，意味着网络设备期望配置的这些参考信号是同步的，或者说其对应的网络设备、天线端口或同一网络设备多面板的传输是同步的，即协同传输。所以第一参考信号和第二参考信号并非限制是来自不同网络设备，其可以是来自不同天线端口，或同一网络设备的不同天线面板。可以通过参考信号资源的标识进行参考信号的指示，也即网络设备配置了各参考信号的时频资源等通信资源，终端设备能够在网络设备配置的资源上接收对应的参考信号，通过参考信号资源的标识，能够标识对应的参考信号。
至少一个第一参考信号和至少一个第二参考信号关联同步测量时，可以将第一参考信号和第二参考信号中一方作为基准对象，另一方作为比对对象，以关联同步测量。可选的，第一参考信号可以作为基准参考信号(也可称作锚点参考信号)，所述第二参考信号为比对参考信号；或，所述第一参考信号为比对参考信号，所述第二参考信号为基准参考信号。所述基准参考信号是指作为一个基准点的参考信号，所述比对参考信号是以基准参考信号为基准点，相比基准参考信号进行偏差计算的参考信号。
当至少包括一个基准参考信号时，终端设备可以根据该多个基准参考信号作为测量的参考。如，终端设备联合得到最终基准值。以时域测量为例，比如说终端设备根据多个基准参考信号测得平均到达时间(也可称作定时或者平均时延)，这个平均到达时间作为最终基准值。其中，平均到达时间仅为示例，具体实现时可以是取平均值，或者去除最大值和最小值之后的中间值，或者根据多个基准参考信号在较强径(信号接收功率较高的传输路径)的到达时间取平均等等，本申请对此不做限定。这里的平均可以是指算数平均、几何平均、加权平均等。或者，可以将一个或多个比对参考信号相对于多个 基准参考信号分别进行测量。
在步骤220中，网络设备发送所述第一指示信息，终端设备接收所述第一指示信息。
第一指示信息可以通过RRC、MAC CE、DCI中至少一种承载。
如果网络系统中多个网络设备进行协同传输，可以通过主网络设备发送所述第一指示信息，也可以通过选举出的辅网络设备发送所述第一指示信息，本申请对此不做限定。其中，主网络设备可以是指UE接入的网络设备，或UE进行RRC连接的网络设备，也可以是以其他规则设置的网络设备，本申请对此不做限制。
在某些可能的实现方式中，通过指示至少一个第一参考信号对应的参考信号资源和至少一个第二参考信号对应的参考信号资源关联同步测量，来指示至少一个第一参考信号和至少一个第二参考信号关联同步测量。可以通过以下方式种任一种或多种方式进行指示：用新增信令进行指示或用现有信令中新增字段进行指令或复用现有信令进行指示或复用现有信令中现有字段进行指示。
在某些可能的实现方式中，所述第一指示信息包括TCI state信息，用于指示所述至少一个第一参考信号对应的参考信号资源与所述至少一个第二参考信号对应的参考信号资源之间具有准共址QCL关系。多个参考信号资源之间具有QCL关系可以是指每一参考资源内的天线端口与其他参考信号资源内的天线端口之间具有QCL关系。当要指示至少一个第一参考信号和至少一个第二参考信号关联同步测量，可以通过传输配置指示状态TCI state信息进行指示，指示所述至少一个第一参考信号对应的资源与所述至少一个第二参考信号对应的资源之间具有QCL关系，来指示终端设备至少一个第一参考信号和至少一个第二参考信号关联同步测量。关于QCL关系的描述，在上文中有统一介绍，在此不再赘述。
可选的，以所述第一参考信号为基准参考信号，所述第二参考信号为比对参考信号为例，以下给出配置的示例，总的来说是将TCI#1配置为第二参考信号的配置信息，即，网络设备为第二参考信号配置第一TCI状态(TCI#1)，其中，第一TCI状态中包含第一参考信号指示，第一TCI状态中还可以包含第一参考信号所关联的准共址QCL类型。但应注意本申请并不限于此：
具体的以CSI-RS为例，网络设备可以将CSI-RS resource#1(即对应所述第一参考信号)作为一个同步测量的基准参考，并将这个信息配置为TCI通知给终端设备：
TCI#1 CSI-RS resource#1
接收到这个配置信息，终端设备侧维护的对应关系则为：
TCI#1 CSI-RS resource#1
之后，网络设备可以配置CSI-RS resource#2(即对应所述第二参考信号)。
CSI-RS resource#2 TCI#1
接收到这个配置信息，终端设备侧维护的关联同步测量的对应关系则为：
CSI-RS resource#2 CSI-RS resource#1
当前配置的CSI-RS resource#2可称为目标参考信号资源，而作为参考的在先配置的CSI-RS resource#1可称为源参考信号资源。可见，通过上面的TCI state配置，网络设备能够指示终端设备CSI-RS resource#2和CSI-RS resource#1关联同步测量，即第二参考信号和第一参考信号关联同步测量，终端设备以第一参考信号为基准，测量第 二参考信号相对于第一参考信号的同步偏差。
可选的，第一指示信息可以指示一个或多个第二参考信号的准共址QCL信息。如，网络设备为多个第二参考信号(可以认为是第二参考信号集合，当然第二参考信号集合的概念也可以包括集合中只有一个第二参考信号)配置第二TCI状态，其中，第二TCI状态中包含第一参考信号指示，第二TCI状态中还可以包含第一参考信号所关联的准共址类型。则意味着，多个第二参考信号(或称第二参考信号集合)都是与第二TCI状态中的第一参考信号关于所关联的准共址QCL类型中的信道大尺度参数而具有QCL关系的。
应理解，本申请实施例并不限于此，对于以上示例，还可以将所述第一参考信号为对比参考信号，所述第二参考信号为基准参考信号，即当前配置的目标参考信号资源(CSI-RS resource#2)对应的参考信号为基准参考信号，而在先配置的源参考信号资源(CSI-RS resource#1)对应的参考信号为比对参考信号。终端设备以第二参考信号为基准，测量第一参考信号相对于第二参考信号的同步偏差。
可选的，在以上通过TCI state配置QCL关系时，如有需要可以具体进一步指示所述QCL关系关联的信道大尺度参数的指示信息，用以指示所述QCL关系的类型，可以复用现有的类型，也可以新增新的类型定义。大尺度参数可以至少包括平均延迟(average delay)，延迟扩展(delay spread)中的至少一项，可以通过信道大尺度参数的指示信息，指示至少一个第一参考信号对应的参考信号资源与所述至少一个第二参考信号对应的参考信号资源之间具有至少关于平均延迟，延迟扩展中的至少一项的准共址QCL关系。
在步骤230中，终端设备根据所述第一指示信息，对所述至少一个第一参考信号和所述至少一个第二参考信号进行同步测量。
终端设备根据网络设备的第一指示信息，可以确定对配置的至少一个第一参考信号和至少一个第二参考信号进行同步测量，进而对所述至少一个第一参考信号和所述至少一个第二参考信号进行同步测量。具体的，可以根据网络设备配置的参考信号资源，在对应的参考信号资源上进行参考信号的接收，并进行同步测量。以对一个第一参考信号和一个第二参考信号进行同步测量为例进行描述，记第一参考信号到终端设备的时延为t1，第二参考信号到终端设备的时延为t2，因为涉及协同传输，这里可以理解时延即为终端设备对参考信号的接收时间，第一参考信号和第二参考信号之间的时延差为θ(时延差也可以等效为：以基准参考信号的到达时间为起点时间，比对参考信号的接收相对于所述起点时间经过了多长的时间)。时域信号经过时延为θ的传输，就意味着在频域上产生正比于θ为斜率的相位变化。如下面的公式，信号s的时域上偏移了θ，则在频域信号上产生了以
Figure PCTCN2019123418-appb-000001
为斜率的相位变化。
Figure PCTCN2019123418-appb-000002
其中，DFT{}表示对一个时域信号进行傅里叶变换，得到频域信号。s是时域信号。k是信号序列中的标识，k为正整数，θ是时域偏移量，X是未经过时延的信号的频域表示，Y是信号经过时延的频域表示，e是自然对数，N是傅里叶变换的长度，N为大于等于1的正整数，π是圆周率，j为虚数单位。可以看到，信号经过时延，等效为在频域上，信号发生了相位的线性变化。
因此，终端设备可以在时域上对信号进行时延测量，或在频域上对信号进行相位测 量。具体测量时，可选的，如果第一参考信号和第二参考信号有区分基准参考信号或比对参考信号，则同步测量可以是测量比对参考信号相对于基准参考信号的传输时延差和/或相位变化，将其作为测量结果。
基准参考信号包括至少一个时，可以首先测量确定上文所述最终基准值，再将一个或多个比对参考信号相对于所述最终基准值进行传输时延差和/或相位变化的测量，得到测量结果。或者，可以将一个或多个比对参考信号相对于多个基准参考信号分别进行测量，然后将多个测量结果合并，可选的还可以对多个测量结果取平均或根据预设规则进一步操作获取最终测量结果。
应理解，传输时延差和/或相位变化仅是传输偏差测量的示例性手段，本申请并不限于此，本申请实施例还可以采用时延比值等手段，在此不一一例举。
上述关联同步测量的参考信号并非实际上一定能够满足同步的期望，本申请实施例的发送和接收指示的方法，通过网络设备的指示，能够使终端设备确定对哪些参考信号进行同步测量，以确定信号传输同步的情况，如同步的偏差等。
图3是从设备交互的角度示出的本申请实施例提供的发送和接收指示的方法300的示意性流程图。需要说明的是，本实施例及后续实施例皆以终端设备与网络设备之间交互为例进行描述，本申请不限于此。为了便于方案理解，在描述时，本实施例及后续实施例皆以终端设备和网络设备多侧的行为展开，从交互多方的角度进行整体描述，但绝非限定系统中改进在于交互各侧的步骤必须合在一起执行，本申请提出的技术方案，在系统中每一侧均有改进。
本实施例与图2对应的实施例的区别在于，本实施例从天线端口组角度进行同步测量，与上述实施例相同或相似的内容在此不再赘述。
如图3所示，本申请实施例的方法300可以包括步骤310至步骤330。下面详细说明方法300中的各步骤：
在步骤310中，网络设备生成第一参考信号资源对应的第一指示信息，所述第一指示信息用于指示关联同步测量的M个天线端口组，M为大于等于2的正整数。
需要说明的是，本实施例中第一参考信号资源与图2对应的实施例中涉及的第一参考信号无必然关联关系，本实施例中第一指示信息与图2对应的实施例中第一指示信息无必然关联关系，本实施例与图2对应的实施例是独立的技术方案描述。
第一指示信息对应第一参考信号资源，即与第一参考信号资源对应的参考信号传输相关联，通过第一指示信息指示的M个天线端口组，是网络设备配置用于传输所述第一参考信号资源对应的参考信号的天线端口组，相当于M个天线端口组协同传输实现第一参考信号资源对应的参考信号的传输，所以网络设备期望配置的M个天线端口组的传输是同步的，否则终端设备对所述参考信号的接收或解码的性能会下降。一个天线端口组中可以包括一个或多个天线端口。不同天线端口组上传输的信号经历的信道的大尺度参数不同。比如说，不同天线端口组可以代表参考信号传输在空间上不同的方向，或者对应不同的波束，本申请对此不作限定。网络设备可以通过天线端口组的标识进行天线端口组的指示。
所述M个天线端口组关联同步测量，可以将所述M个天线端口组中至少一个天线端口组作为基准天线端口组。
M个天线端口组关联同步测量，可以将所述至少一个天线端口组作为基准天线端口 组，M个天线端口组中的其余天线端口组作为比对天线端口组，以关联同步测量。所述基准天线端口组是指其传输作为一个参考点的天线端口组，所述比对天线端口组是以基准天线端口组的传输为基准点，相比基准天线端口组的传输进行传输偏差计算的天线端口组。
当有至少一个基准天线端口组时，终端设备可以根据该多个基准天线端口组的传输作为测量的参考。如，终端设备联合得到最终基准值。以时域测量为例，比如说终端设备根据多个基准天线端口组传输的参考信号测量计算得到平均到达时间(也可称作定时或者平均时延)，这个平均到达时间作为最终基准值。其中，平均到达时间仅为示例，具体实现时可以是取平均值，或者去除最大值和最小值之后的中间值，或者根据多个基准天线端口组传输的信号在较强径(信号接收功率较高的传输路径)的到达时间取平均等等，本申请对此不做限定。这里的平均可以是指算数平均、几何平均、加权平均等。或者，可以将一个或多个比对天线端口组的传输相对于多个基准天线端口组的传输分别进行测量。
可选的，所述M个天线端口组中包括N个码分复用(code division multiplexing，CDM)组。码分复用CDM组内的多个天线端口可以占据相同的时频资源，但使用不用的码域资源，它们应用时域和/或频域上正交的码来区分，其中N为正整数。其中一个所述天线端口组中可以包括一个或多个CDM组，一个CDM组中的天线端口不会包括在多个所述天线端口组中。可以认为同一CDM组内的天线端口传输的信号是能够被同时接收，如果不同CDM组关联同步测量，则不同CDM组的传输也是被期望同步的。
在步骤320中，网络设备发送所述第一指示信息，终端设备接收所述第一指示信息。
第一指示信息可以通过RRC、MAC CE、DCI中至少一种承载。
如果系统中多个网络设备进行协同传输，可以通过主网络设备发送所述第一指示信息，也可以通过选举出的辅网络设备发送所述第一指示信息，本申请对此不做限定。其中，主网络设备可以是指终端设备接入的网络设备，或终端设备进行RRC连接的网络设备，也可以是以其他规则设置的网络设备，本申请对此不做限制。
关于所述第一指示信息实现指示的具体方式不限，以下给出一些示例，应理解本申请不限于此：
示例1、根据预设的规则，比如一个CSI-RS资源内，预设某些天线端口(例如，预设某些CDM组的标识指示的CDM组内的天线端口)是基准天线端口。网络设备指示终端设备用该CSI-RS进行同步测量时，则终端设备将这个CSI-RS资源内符合预设条件的天线端口作为基准天线端口，组成一个或多个基准天线端口组，其他的天线端口作为比对天线端口，组成一个或多个比对天线端口组。
示例2、网络设备为某CSI-RS配置准共址信息，其中至少包括了参考信号指示。当某CSI-RS资源的配置信息中，准共址信息的配置信息里配置的参考信号是这个CSI-RS资源本身时，终端设备得知这个CSI-RS资源内的部分天线端口是用来作为基准天线端口的(而是哪些天端口，也可以通过“示例1”中的举例如预设规则来实现，或者是准共址信息中除了参考信号指示之外，还包括了天线端口(或天线端口组)的指示信息)。以类似图2实施例的配置实例进行说明：
网络设备可以将CSI-RS resource#1(对应CSI-RS#1)配置为TCI#1通知给终端设 备：
TCI#1 CSI-RS resource#1
之后，网络设备可以为终端设备配置CSI-RS#1的QCL信息，其中TCI#1中携带了参考信号指示(即上面配置的CSI-RS resource#1)，所以QCL信息的配置信息里配置的参考信号是这个CSI-RS#1的资源本身：
CSI-RS resource#1 TCI#1
示例3、网络设备配置某参考信号用于同步测量，网络设备还为终端设备显式地配置这个参考信号资源内的哪些天线端口(或天线端口组)是作为基准天线端口(或天线端口组)的，其中基准天线端口可以组成一个或多个基准天线端口组。
在步骤330中，终端设备根据所述第一指示信息，对所述M个天线端口组进行同步测量。
终端设备根据网络设备的第一指示信息，可以确定对配置的M个天线端口组的传输进行同步测量，进而对配置的M个天线端口组的传输进行同步测量，具体的，可以在网络设备配置所述第一参考信号资源上接收参考信号，对各天线端口组对应的信道进行同步测量。以对天线端口组1和天线端口组2进行同步测量为例进行描述，记在所述第一参考信号资源上从天线端口组1对应的信道上传输的参考信号到终端设备的时延为t1，在所述第一参考信号资源上从天线端口组2对应的信道上传输的参考信号到终端设备的时延为t2，因为涉及协同传输，这里可以理解时延即为终端设备对参考信号的接收时间，天线端口组1和天线端口组2之间传输时延差为θ(时延差也可以等效为：以天线端口组1对应信道传输的参考信号的到达时间为起点时间，天线端口组2对应信道传输的参考信号的接收相对于所述起点时间经过了多长的时间)。时域信号经过时延为θ的传输，就意味着在频域上产生正比于θ为斜率的相位变化，具体图2对应的实施例已描述，在此不再赘述。
因此，终端设备可以在时域上对信号进行时延测量，或在频域上对信号进行相位测量。具体测量时，可选的，如果天线端口组有区分基准天线端口组或比对天线端口组，则同步测量可以是测量比对天线端口组相对于基准天线端口组的传输时延差和/或相位变化，将其作为测量结果。
基准天线端口组包括至少一个时，可以首先测量确定所述最终基准值，再将一个或多个比对天线端口组的传输相对于所述最终基准值进行传输时延差和/或相位变化的测量，得到测量结果。或者，可以将一个或多个比对天线端口组相分别对于多个基准天线端口组的传输进行测量，然后将多个测量结果合并，可选的还可以对多个测量结果取平均或根据预设规则进一步操作获取最终测量结果。
应理解，传输时延差和/或相位变化仅是传输偏差测量的示例性手段，本申请并不限于此，本申请实施例还可以采用时延比值等手段，在此不一一例举。
上述关联同步测量的M个天线端口组的传输并非实际上一定能够满足同步的期望，本申请实施例的发送和接收指示的方法，通过网络设备的指示，能够使终端设备确定同步测量，以确定天线端口组传输同步的情况，如同步的偏差等。
图4是从设备交互的角度示出的本申请实施例提供的发送和接收指示的方法400的示意性流程图。图4对应的实施例以图2或图3对应的实施例为基础，与以上图2或图3对应实施例的区别在于，该实施例侧重终端设备根据所述第一指示信息，确定进行同步 测量之后的后续方案描述，与图2或图3对应实施例相同或相关的内容，在本实施例中不再赘述。
如图4所示，本申请实施例的方法400可以包括步骤410至步骤440。下面详细说明方法400中的各步骤。
在步骤410中，网络设备生成第一指示信息。
在步骤420中，网络设备发送所述第一指示信息，终端设备接收所述第一指示信息。
在步骤430中，终端设备根据所述第一指示信息，进行同步测量。
上述步骤410-430与图2中步骤210-230或图3中步骤310-330对应实施例的步骤相关，在此不再赘述。
在步骤440中，所述终端设备向所述网络设备发送第二指示信息，所述第二指示信息用于指示所述同步测量的结果；和/或所述终端设备向所述网络设备发送信道状态信息CSI，所述CSI根据所述同步测量的结果获得。
可选的，所述CSI至少包括预编码矩阵指示PMI和/或信道质量指示CQI，所述PMI和/或CQI根据所述同步测量的结果获得。
可选的，所述第二指示信息可以携带在CSI中上报给网络设备。
终端设备进行了同步测量，获得同步测量的结果后，可以将同步测量的结果上报给网络设备，使得网络设备可以根据终端设备的上报，对传输的信号进行调整，保证传输的同步，进一步保证了协同传输的性能。可以理解，将同步测量的结果上报给网络设备可以通过显式或隐式、直接或间接的指示方式进行上报。终端设备可以直接上报同步测量结果，直接上报时可以是和其他上行控制信息(uplink control information，UCI)进行独立的或关联的编码。其中，这个结果和其他UCI信息之间的具有定义好的顺序关系。示例性的，终端设备在上报所述传输时延差和/或相位变化的信息时，上报的是传输时延差和/或相位变化的信息的函数的结果，所述函数可以是一个量化函数，所述量化函数可以提供上报区间(即时延差区别和/或相位变化区间)内均匀的、或者非均匀的量化方法。比如说，终端设备测量得到的时延信息，可以经过量化上报。如量化为将时延信息与条件比对，选择符合条件的结果作为上报量。
下面举一个量化的例子：在时延上报的区间范围，时延信息落在区间内的不同的位置对应了不同的上报信息。如时延若符合第一区间则上报量为第一值，第一区间可以是[T1,T2],或(T1,T2)，或[T1,T2)，或(T1，T2]，其中，T1<＝T2，T1、T2是区间的边界确立参考点。如时延若符合第二区间则上报量为第二值，第二区间可以是与第一区间正交的区间，本申请对此不进行限制。以此类推，另外，当时延大于第一阈值(量化的上限)时，终端可以上报特定值，或者是终端可以上报特定信息；当时延小于第二阈值(量化的下限)时，终端可以上报特定值，或者是终端可以上报特定信息。这里的特定信息的含义是该信息可以用来表示时延信息超出了终端期望的范围。不同的区间的长度可以不一样，也就是非均匀的量化。
采用这些方法是因为，终端测得的时延信息或相位变化信息，可能是连续的量，但是在上报的时候，可能只能上报一些离散的信息，所以需要采用某种手段，将时延信息或相位变化信息与上报信息做一个映射。
终端设备还可以将所述传输时延差和/或相位变化的信息，或经过函数计算的所述传输时延差和/或相位变化的信息调制在其他信号上，进行发送，使得网络设备隐式地得到 这个信息。其他信号可以是PTRS、信道探测参考信号(sounding reference signal，SRS)、解调参考信号(demodulation reference signal，DMRS)等。举个例子，如传输SRS所使用的序列是在一个基序列上乘上一个相位。那么在这个地方，测量出来的相位变化可以与SRS本身的相位进行变换后，作为SRS序列的相位。SRS本身的相位是指SRS的循环移位量。这里的变换可以是指两者的乘法、加法等。
终端设备进行了同步测量，获得同步测量的结果后，可以根据同步测量的结果，进行信道估计，计算确定CSI，也就是说终端设备考虑了传输时延和/或相位，基于假设传输时延和/或相位调整后的等效信道，进行信道质量的测量。以CSI包括的预编码矩阵指示PMI和/或信道质量指示CQI为例，终端设备上报的PMI可以是考虑了传输时延和/或相位调整后的等效信道所计算的PMI。终端设备上报的CQI可以是考虑了传输时延和/或相位调整后的等效信道所计算的CQI。也就是说，终端计算CQI、PMI等的时候，是假设基站的传输会根据所述传输时延和/或相位进行传输时延和/或相位调整的，即假设协同传输是同步的(没有偏差，或者偏差小于某一阈值，在阈值以内都认为是同步的)。具体CSI的计算可参考现有技术，在此不再赘述。
本申请实施例的发送和接收指示的方法，通过向网络设备报告同步测量结果，或者调整估计的PMI和/或CQI后，从而向网络设备报告测量结果和/或信道测量结果。网络设备基于收到的信息之后，可以在时域上对信号发送进行时间的调整，或者是在频域上对信号发送进行相位的调整。
需要说明的是，图1中对信号传播路径的示意并非限制网络设备与终端设备只有主径(信号传播由网络设备直接到终端设备的路径))的场景，以上图2-图4的实施例中，可以应用在单径(只有主径)或多径(具有反射径，即信号传播由网络设备到反射体，再由反射体到终端设备的路径)的任一场景下。对于单径或多径场景下，信号传播的时延(或称到达时间)的测量，现有技术中已有相关方案，在此不再赘述。
图5是从设备交互的角度示出的本申请实施例提供的发送和接收指示的方法500的示意性流程图。图5对应的实施例以图2至图4对应的实施例为基础，与以上图2至图4对应实施例的区别在于，该实施例侧重网络设备之间的交互，是同步测量的结果上报之后的后续方案描述，与图2至图4对应实施例相同或相关的内容，在本实施例中不再赘述。
如图5所示，本申请实施例的方法500可以包括步骤510至步骤550。下面详细说明方法500中的各步骤。
在步骤510中，第一网络设备接收终端设备上报的同步测量的结果。
可选的，所述第一网络设备为终端设备接入的主服务小区的网络设备。当然所述第一网络设备也可以是其他选举出的网络设备，可以与指示终端设备进行同步测量的网络设备为同一网络设备或不同网络设备。
在步骤520中，当所述第一网络设备与所述至少一个第二网络设备之间没有协调过上行资源(即，所述至少一个第二网络设备不知道上行资源的位置，不能够接收同步测量的结果)，则所述第一网络设备将所述同步测量的结果发送给所述至少一个第二网络设备，或者所述第一网络设备将调节量信息发送给所述至少一个第二网络设备。
当各网络设备之间能够基于预先确定的调整规则，根据同步测量的结果进行传输参数的调整，那么则所述第一网络设备将所述同步测量的结果发送给所述至少一个第二网 络设备。如果第二网络设备无法获知预先确定的调整规则，则可选的，第一网络设备可以直接将传输参数的调节量信息发送给所述至少一个第二网络设备。可以理解的是，所述传输参考包括信号的发送时间，相位等参数。
在步骤530中，至少一个第二网络设备接收终端设备上报的同步测量的结果。
当所述第一网络设备与至少一个第二网络设备之间协调过上行资源(即，所述第一网络设备和所述至少一个第二网络设备均已知上行资源的位置，能够进行同步测量的结果的接收)，则所述第一网络设备无需将所述同步测量的结果发送给所述至少一个第二网络设备。
可以理解，步骤530与步骤520为可选的步骤，这两个步骤的存在依赖上述条件。当具有存在步骤530的条件时，步骤530与步骤510无必然的先后关系。
