Description

波束上报的方法和通信装置
本申请要求于2018年11月19日提交中国专利局、申请号为201811378725.9、申请名称为“波束上报的方法和通信装置”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
本申请涉及通信领域，特别涉及一种波束上报的方法和通信装置。
背景技术
在未来的通信系统中，例如第五代移动通信(5th-Generation，5G)系统中，仅仅利用低于6GHz频段的低频通信已经不能满足日益增长的通信需求，因此频率大于6GHz的高频通信(high frequency，HF)越来越受到学界和业界的重视。然而由于HF信号在空间中能量衰减快，穿透能力弱，信号路损远大于低频信号。因此，为了在高频场景下对抗路径损耗，需要利用天线侧的增益来补偿这一部分损失，从而保证HF系统的覆盖。此外，由于在HF场景下，信号的波长更短，天线的体积更小，大规模天线阵的多天线技术(Massive-MIMO)也更适合于应用在HF场景。利用Massive-MIMO技术，发射侧例如网络设备侧可以用数字和模拟的方式形成能量更集中的发射波束来保证系统覆盖，接收侧例如终端设备侧同样可以形成能量更集中的接收波束增加接收增益。
由于HF系统中收发双方都倾向于利用窄波束进行通信，窄波束的相互匹配显得尤为重要，网络设备和终端设备可通过波束(beam)训练来获取发射波束与接收波束之间的配对关系。
协作多点(coordination multiple point，CoMP)作为适用于提升小区边缘用户吞吐的传输技术，一个终端设备可能会同时与多个传输接收点(transmission and reception point，TRP)通信。按照现有的波束训练方式，在CoMP系统中，终端设备上报的波束可能会来自于同一个TRP，导致终端设备无法实现与同时通信的多个TRP进行波束训练。
因此，如何进行CoMP系统中的波束训练，成为亟待解决的问题。
发明内容
本申请提供一种波束上报的方法和通信装置，能够实现CoMP系统中的波束训练。
第一方面，提供了一种波束上报的方法，该方法包括：终端设备接收第一信息，所述第一信息用于配置至少两个参考信号资源组；
所述终端设备发送上报信息，所述上报信息包括至少两个波束的相关信息，所述至少两个波束用于发送承载在至少两个参考信号资源上的参考信号，所述至少两个波束发送的参考信号能够被所述终端设备同时接收；
其中，所述至少两个参考信号资源分别来自于所述至少两个参考信号资源组。
第二方面，提供了一种波束上报的方法，该方法包括：
网络设备发送第一信息，所述第一信息用于配置至少两个参考信号资源组；
所述网络设备接收终端设备发送的上报信息，所述上报信息包括至少两个波束的相关信息，所述至少两个波束用于发送承载在至少两个参考信号资源上的参考信号，所述至少两个波束发送的参考信号能够被所述终端设备同时接收；
其中，所述至少两个参考信号资源分别来自于所述至少两个参考信号资源组。
具体地，本申请实施例中，将参考信号资源分组，例如，一个参考信号资源组可以对应联合传输中的一个网络设备，终端设备选择上报的波束分别选自不同的发送波束资源组，且终端设备上报的波束能够被该终端设备同时接收到。也就是说，本申请实施例中，针对每个参考信号资源组上报至少一个波束的相关信息，进而能够实现对该组参考信号资源对应的网络设备的发送波束的训练，因此，本申请实施例能够通过一次扫描实现对联合传输的多个网络设备的下行波束进行训练的目的。
应理解，本申请实施例中，该至少两个参考信号资源的个数可以与至少两个参考信号资源组的个数相等，这种情况下，该至少两个参考信号资源包括每一个参考信号资源组中的一个参考信号资源。也就是说，针对每个参考信号资源组，终端设备上报一个参考信号资源对应的波束的相关信息。
可选地，该至少两个参考信号资源的个数可以大于至少两个参考信号资源组的个数，这种情况下，该至少两个参考信号资源是由每一个参考信号资源组中的一个或多个参考信号资源构成。也就是说，针对每个参考信号资源组，终端设备上报一个或多个参考信号资源对应的波束的相关信息。
需要说明的是，本申请实施例中，终端设备具有同时接收该至少两个波束发送的参考信号的能力。在实际应用中，网络设备可以通过该至少两个波束同时发送参考信号，也可以是先后发送参考信号，也就是说，终端设备可以同时接收该至少两个波束发送的参考信号，也可以是先后接收该至少两个波束发送的参考信号，终端设备可能通过同一个接收波束接收所述至少两个波束发送的参考信号，也可能通过可同时存在的至少两个接收波束同时接收所述至少两个波束发送的参考信号，具体终端设备如何判定具有上述能力为终端设备实现，不申请实施例并不限定。
可选地，在一种实现方式中，本申请实施例中的至少两个波束的相关信息包括上述至少两个参考信号接收功率以及与所述至少两个参考信号接收功率一一对应的所述至少两个参考信号资源的标识。
应理解，本申请实施例中，波束的相关信息可以具有多种可能的形式，只要该波束的相关信息能够实现指示终端设备选择上报上述至少两个波束即可，本申请实施例并不限于上述参考信号接收功率及参考信号资源的标识。例如，至少两个波束的相关信息还可以是该至少两个波束发送的参考信号的信噪比等。
结合第一方面或第二方面，在一种可能的实现方式中，所述第一信息携带在以下一个或多个信令中：
无线资源控制RRC信令、媒体接入控制控制元素MAC-CE和下行控制信息DCI。
结合第一方面或第二方面，在一种可能的实现方式中，所述第一信息携带在RRC中时，所述参考信号的发送方式为周期方式；或，
所述第一信息携带在MAC-CE中时，所述参考信号的发送方式为半持续方式；或，
所述第一指令携带在DCI中时，所述参考信号的发送方式为非周期方式。
结合第一方面或第二方面，在一种可能的实现方式中，所述参考信号资源组为参考信号资源集合，其中，所述第一信息通过直接配置、激活或触发至少两个参考信号资源集合来配置所述至少两个参考信号资源组。
在本申请实施例中，一个资源配置(resource setting)中的资源类型(resource type)可以被配置为周期(periodic)、半持续(semi-persistent)和非周期(aperiodic)三种时域周期行为。针对该三种周期行为，网络设备可以直接配置、激活或触发至少两个参考信号资源集实现配置至少两个参考信号资源。
本申请实施例中，通过网络设备直接配置、激活或触发多个resource set，实现参考信号资源分组，并针对每个资源上报至少一个波束的相关信息来实现与该资源对应的网络设备的波束训练的目的。
结合第一方面或第二方面，在一种可能的实现方式中，所述第一信息包括同一个参考信号资源集合中参考信号资源的准共址QCL配置信息，其中，具有相同QCL配置信息的参考信号资源被配置为同一参考信号资源组。
结合第一方面或第二方面，在一种可能的实现方式中，所述QCL配置信息为与参考信号资源一一对应的传输配置指示TCI状态标识。
本申请实施例通过将具有相同QCL配置信息的参考信号资源配置为同一参考信号资源组，实现了配置上述至少两个参考信号资源组，由于不同的网络设备对应不同的参考信号资源组，针对每个参考信号资源组终端设备上报其对应的一个或多个波束的相关信息，进而本申请实施例实现了对联合传输的多个网络设备的下行波束同时训练的目的。
结合第一方面或第二方面，在一种可能的实现方式中，所述第一信息为资源配置信息，所述资源配置信息通过配置同一个参考信号资源集合中参考信号资源的标识序号实现对至少两个参考信号资源组的配置。
本申请实施例通过将参考信号资源序号满足规则的参考信号资源划分为同一参考信号资源组，实现了配置上述至少两个参考信号资源组，由于不同的网络设备对应不同的参考信号资源组，针对每个参考信号资源组终端设备上报其对应的一个或多个波束的相关信息，进而本申请实施例实现了对联合传输的多个网络设备的下行波束同时训练的目的。
结合第一方面，在一种可能的实现方式中，在所述终端设备发送上报信息之前，所述方法还包括：
所述终端设备接收网络设备发送的指示信息，所述指示信息用于指示多波束分组上报模式为开启状态，其中，所述多波束分组上报模式为开启状态表示所述终端设备需要上报所述至少两个波束的相关信息。
结合第二方面，在一种可能的实现方式中，在所述网络设备接收终端设备发送的上报信息之前，所述方法还包括：
所述网络设备向所述终端设备发送指示信息，所述指示信息用于指示多波束分组上报模式为开启状态，其中，所述多波束分组上报模式为开启状态表示所述终端设备需要上报所述至少两个波束的相关信息。
本申请实施例通过在满足一定的条件下，终端设备才按照上述多波束分组上报的方法 发送上报信息，能够将多波束分组上报的方法限定在波束训练的场景下，避免了其他场景下采用此方法发送上报信息的情况。

在一种实现方式中，该通信装置为终端设备。
第四方面，提供了一种通信装置，包括用于执行第二方面或第二方面中任一种可能实现方式中方法的各个模块或单元。

本申请中的“协作多点传输”包括但不限于联合传输JT。JT包括相干JT和非相干JT(NCJT)，两者的区别在于NCJT对来自多个协作TRP的不同的MIMO数据流分别做波束赋形，相干JT对来自多个协作TRP的所有MIMO数据流做联合波束赋形。
在本申请实施例中，第一网络设备可以作为服务网络设备，该第二网络设备可以为协作网络设备；或者，第一网络设备可以为协作网络设备，第二网络设备为服务网络设备；或者，第一网络设备和第二网络设备也可以都为服务网络设备，本申请实施例并不限于此。

下面对本申请实施例中涉及的一些概念说明如下：
“波束”，可以理解为空间滤波器(spatial filter)或空间参数(spatial parameters)。用于发送信号的波束可以称为发射波束(transmission beam，Tx beam)，可以为空间发送滤波器(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)，可以为空间接收滤波器(spatial domain receive filter)或空间接收参数(spatial domain receive parameter)。
形成波束的技术可以是波束赋形技术或者其他技术。例如，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。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。
在NR协议中，波束例如可以是空间滤波器(spatial filter)。但应理解，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。
需要说明的是，在下文示出的实施例中，“波束”和“空间滤波器”交替使用，例如“发射波束”和“空间发射滤波器”交替使用，“接收波束”和“空间接收滤波器”交替使用，在不强调其区别时，其所要表达的含义是一致的。
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。
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。
“波束配对关系”即，发射波束与接收波束之间的配对关系，也就是空间发射滤波器与空间接收滤波器之间的配对关系。在具有波束配对关系的发射波束和接收波束之间传输信号可以获得较大的波束赋形增益。
在一种实现方式中，发送端和接收端可以通过波束训练来获得波束配对关系。具体地，发送端可通过波束扫描的方式发送参考信号，接收端也可通过波束扫描的方式接收参考信号。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参考信号发射出去，使得参考信号在发射波束所指向的方向上发射参考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参考信号，使得该接收端接收参考信号的功率在接收波束所指向的方向上可以达到最大。
通过遍历各发射波束和接收波束，接收端可基于接收到的参考信号进行信道测量，并将测量得到的结果通过信道状态信息(channel state information，CSI)上报发送端。例如，接收端可以将参考信号接收功率(reference signal receiving power，RSRP)较大的部分参考信号资源上报给发送端，如上报参考信号资源的标识，或者上报参考信号资源的标识和该参考信号资源对应的RSRP，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。
“参考信号与参考信号资源”：参考信号可用于信道测量或者信道估计等。参考信号资源可用于配置参考信号的传输属性，例如，时频资源位置、端口映射关系、功率因子以及扰码等，具体可参考现有技术。发送端设备可基于参考信号资源发送参考信号，接收端设备可基于参考信号资源接收参考信号。
本申请中涉及的信道测量也包括波束测量，即通过测量参考信号获得波束质量信息，用于衡量波束质量的参数包括RSRP，但不限于此。例如，波束质量也可以通过参考信号接收质量(reference signal receiving quality，RSRQ)，信噪比(signal-noise ratio，SNR)，信号与干扰噪声比(signal to interference plus noise ratio，SINR，简称信干噪比)等参数衡量。本申请实施例中，为方便说明，在未作出特别说明的情况下，所涉及的信道测量可以视为波束测量。
其中，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)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)。
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。
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)。
其中，SSB资源标识也可以称为SSB标识(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。
“上报配置(reporting setting)”：也可以称为信道状态信息CSI上报配置，可以与一个或多个资源配置(resource setting)关联。以参考信号资源为CSI-RS资源为例，用于波束测量时，可以将reporting setting中的上报参数(ReportQuantity)设置为“CRI+RSRP”，即波束的质量或强度通过RSRP来衡量，同时可以通过上报配置类型(ReportConfigureType)配置上报的周期行为包括非周期上报(aperiodic)、周期上报(periodic)或半持续上报(semi-persistent))，例如，如图2所示波束的质量或强度的上报行为为非周期上报。
“资源配置(resource setting)”：关联有一个或多个参考信号资源集(resource set)，且配置资源类型(resource type)为非周期资源(aperiodic)、周期资源(periodic)或半持续资源(semi-persistent)。其中，一个resource set可以包括一个或多个参考信号资源，具体地，参考信号资源可用于配置参考信号的传输属性，例如，时频资源位置、端口映射关系、功率因子以及扰码等。
例如，如图2所示，资源配置(resource setting)关联的resource set可以为非零功率信道状态信息参考信号资源集(NZP-CSI-RS resource set)，资源类型为非周期资源。该NZP-CSI-RS resource set中可以包含有一个或多个NZP-CSI-RS resource，例如，如图2所示包括4个NZP-CSI-RS resource，且各个资源有各自的资源序号(#0-#3)，每一个NZP-CSI-RS resource发送的时候承载在一个波束上，终端设备便可以测量该NZP-CSI-RS resource上传输的CSI-RS的RSRP来比较波束质量。
应理解，本申请实施例中，资源配置(resource setting)关联的资源集(resource set)可以是零功率或非零功率的参考信号资源的集合，本申请实施例并不限于此。应理解，“资源配置(resource setting)”关联资源集(resource set)可以表示资源配置用于配置该资源集，或者资源配置包括该资源集，本申请实施例并不限于此。应理解，本申请实施例中“资源集”也可以称为“资源集合”。
应理解，上文描述的“资源配置”可以适用于参考信号资源为CSI-RS的情况。但本申请实施例的参考信号资源不限于CSI-RS，例如本申请实施例的参考信号资源还可以是SSB或SRS等，具体地，SSB或SRS的资源关联关系可以参考现有技术，此处不再赘述。
需要说明的是如图2所示的重复参数(repetition)配置为ON表示承载这4个 NZP-CSI-RS resource的发射波束是重复的，而设置为OFF则表示没有限定(重复或不重复均可)。
如果该NZP-CSI-RS resource set是周期的，那么当终端设备收到该RRC配置消息时，便根据具体的CSI-RS资源的配置在相应的时频位置上开始接收和测量；如果该NZP-CSI-RS resource set是半持续的，那么终端设备在收到一个相关的MAC-CE激活指令之后，才开始接收和测量，并在收到去激活指令后停止测量；如果该NZP-CSI-RS resource set是非周期的，那么终端设备会在收到一个DCI触发指令后才开始接收和测量，并只测量一次就结束。
应理解，上述上报配置和资源配置可以是网络设备通过高层信令，例如，RRC信令发送的，本申请实施例并不限于此。
“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。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。
“准共址(quasi-co-location，QCL)”：或者称准同位。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：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，空间接收参数(spatial Rx parameters)。其中，空间接收参数可以包括以下的一项或多项：到达角(angle of arrival，AOA)、平均AOA、AOA扩展、离开角(angle of departure，AOD)、平均离开角AOD、AOD扩展、接收天线空间相关性参数、发送天线空间相关性参数、发射波束、接收波束以及资源标识。
其中，上述角度可以为不同维度的分解值，或不同维度分解值的组合。天线端口为具有不同天线端口编号的天线端口，和/或，具有相同天线端口号在不同时间和/或频率和/或码域资源内进行信息发送或接收的天线端口，和/或，具有不同天线端口号在不同时间和/或频率和/或码域资源内进行信息发送或接收的天线端口。资源标识可以包括：CSI-RS资源标识，或SRS资源标识，或SSB资源标识，或物理随机接入信道(Physical Random Access Channel，PRACH)上传输的前导序列的资源标识，或解调参考信号(demodulation reference signal，DMRS)的资源标识，用于指示资源上的波束。
在NR协议中，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的QCL为类型D的QCL。下文中在没有特别说明的情况下，QCL可以理解为类型D的QCL，即，基于空间接收参数定义的QCL。
当QCL关系指类型D的QCL关系时，可以认为是空域QCL。当天线端口满足空域QCL关系时，下行信号的端口和下行信号的端口之间，或上行信号的端口和上行信号的端口之间的QCL关系，可以是两个信号具有相同的AOA或AOD，用于表示具有相同的 接收波束或发射波束。又例如对于下行信号和上行信号间或上行信号与下行信号的端口间的QCL关系，可以是两个信号的AOA和AOD具有对应关系，或两个信号的AOD和AOA具有对应关系，即可以利用波束互易性，根据下行接收波束确定上行发射波束，或根据上行发射波束确定下行接收波束。
从发送端来看，如果说两个天线端口是空域QCL的，则可以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QCL的，则可以是指接收端能够在同一波束方向上接收到这两个天线端口发送的信号。
具有空域QCL关系的端口上传输的信号还可以具有对应的波束，对应的波束包括以下至少之一：相同的接收波束、相同的发射波束、与接收波束对应的发射波束(对应于有互易的场景)、与发射波束对应的接收波束(对应于有互易的场景)。
具有空域QCL关系的端口上传输的信号还可以理解为使用相同的空间滤波器(spatial filter)接收或发送信号。空间滤波器可以为以下至少之一：预编码，天线端口的权值，天线端口的相位偏转，天线端口的幅度增益。
具有空域QCL关系的端口上传输的信号还可以理解为具有对应的波束对连接(beam pair link，BPL)，对应的BPL包括以下至少之一：相同的下行BPL，相同的上行BPL，与下行BPL对应的上行BPL，与上行BPL对应的下行BPL。
因此，空间接收参数(即，类型D的QCL)可以理解为用于指示接收波束的方向信息的参数。
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TCI状态(TCI state)列表，并可以通过高层信令(如MAC CE)或物理层信令(如DCI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的指示激活控制信道TCI状态列表中的一个或多个，其中控制信道TCI状态列表为上述TCI状态列表的一个子集；终端设备可以从PDCCH中获取DCI，进而根据DCI的指示选择数据信道TCI状态列表中的一个或多个TCI状态，其中所述数据信道TCI状态列表为上述TCI状态列表的一个子集，通过MAC-CE信令指示给终端设备。
一个TCI状态的配置信息可以包括一个或两个参考信号资源的标识，以及所关联的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PDCCH或PDSCH。
当QCL关系配置为类型D时，终端设备可以知道网络设备使用哪个发射波束发射信号，进而可以根据信道测量确定的波束配对关系确定使用哪个接收波束接收信号。
需要说明的是，本文中的一些名称及英文简称为以LTE系统或5G系统为例对本申请实施例进行的描述，但本申请实施例并不限于此，其可能随着网络的演进发生变化，具体演进可以参考相应标准中的描述。
在CoMP系统中，一种可选的波束训练方式如下：通过一次波束扫描实现对联合传输的至少两个传输点的下行波束进行训练。例如，如图3所示，在一次波束扫描和上报中，将TRP1和TRP2的波束遍历，此时相当于一个NZP-CSI-RS resource set中的参考信号资 源，分别通过TRP1和TRP2的波束轮询发送。这种情况下，由于两个传输点到终端设备的距离造成一定的功率差，导致终端设备基于RSRP的强度可能会选择来自于同一个传输点的多个波束，例如，TRP1的两个波束进行上报，这种情况后续数据发送时无法实现多点协作。
在CoMP系统中，另一种可选的波束训练方式如下：联合传输的各个传输点分别单独采用一次波束扫描进行下行波束进行训练。例如，如图4所示，分两次波束扫描和上报，分别扫描TRP1和TRP2的波束，此时相当于有两个上报配置(reporting setting)，分别关联到两个参考信号资源集合(resource set)，这两个resource set中的参考信号资源分别通过TRP1和TRP2的波束轮询发送。此时终端设备会在第一次波束扫描后从TRP1选择一个波束上报，再在第二次波束扫描后从TRP2选择一个波束上报。但这种情况下，终端设备用于接收选择并上报的不同TRP的发射波束的接收波束可能不是同一个，也可能这两个接收波束可能不能同时存在，那么当两个TRP分别通过它们各自的发射波束与终端设备通信时，终端设备可能无法同时接收两个TRP发送的信号，只能接收到其中一个TRP的信号，对通信业务造成影响。
综上，可以得出上述CoMP系统中两种波束训练方式都存在一些不足，因此如何进行CoMP系统中的波束训练，成为亟待解决的问题。
鉴于上述问题，本申请实施例提出了一种波束训练的方法，能够解决上述问题，具体地，本申请通过一次波束扫描实现上报至少两个传输点的波束的相关信息，实现CoMP系统中的波束训练。
具体而言，本申请实施例中，可以将参考信号资源分组，例如，一个参考信号资源组可以对应联合传输中的一个网络设备，终端设备选择上报的波束分别选自不同的发送波束资源组，且终端设备上报的波束能够被该终端设备同时接收到，进而实现了一次扫描实现对联合传输的多个网络设备的下行波束进行训练的目的。
以下，为了便于理解和说明，作为示例而非限定，结合图5对本申请中的方法在通信系统中的执行过程和动作进行说明。

图5是根据本申请一个实施例的多波束分组上报的方法500的示意性流程图。图5所示的方法可以应用于如图1所示支持CoMP的通信系统中。应理解，图1所示的本申请实施例可适用的联合传输场景，可以是同构网络的联合传输场景，也可以是异构网的联合传输场景，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场景，也可以是高频场景，本申请实施例并不对此做限定。
具体地，如图5所示的方法500包括：
510，网络设备发送第一信息，所述第一信息用于配置至少两个参考信号资源组；
相对应地，终端设备接收该第一信息。
应理解，该网络设备可以是CoMP中的多个网络设备的任意一个网络设备。例如，该第一信息是由服务网络设备或协作网络设备发送的，本申请实施例并不限于此。
应理解，该至少两个参考信号资源组可以与联合传输的至少两个网络设备一一对应，换句话说，联合传输的每个网络设备对应一个参考信号资源组，每个网络设备可以通过其对应的该参考信号资源组中的资源发送参考信号。
应理解，本文中仅以应用于CoMP系统中为例，描述本申请实施例的方法，但本申请实施例并不限于此，本申请实施例的方法还可以应用于其他场景中，例如，可以应用于单传输点传输的场景中。
应理解，本申请实施例中的至少两个参考信号资源组也可以对应于同一个网络设备，本申请实施例并不限于不同的参考信号资源组对应不同的网络设备的场景。
520，所述终端设备发送上报信息，所述上报信息包括至少两个波束的相关信息，所述至少两个波束用于发送承载在至少两个参考信号资源上的参考信号，所述至少两个波束发送的参考信号能够被所述终端设备同时接收；其中，所述至少两个参考信号资源分别来自于所述至少两个参考信号资源组。
相对应地，所述网络设备接收终端设备发送的上报信息。
具体地，本申请实施例中，将参考信号资源分组，例如，一个参考信号资源组可以对应联合传输中的一个网络设备，终端设备选择上报的波束分别选自不同的发送波束资源组，且终端设备上报的波束能够被该终端设备同时接收到。也就是说，本申请实施例中，针对每个参考信号资源组上报至少一个波束的相关信息，进而能够实现对该组参考信号资源对应的网络设备的发送波束的训练，因此，本申请实施例能够通过一次扫描实现对联合传输的多个网络设备的下行波束进行训练的目的。
应理解，本申请实施例中，该至少两个参考信号资源的个数可以与至少两个参考信号资源组的个数相等，这种情况下，该至少两个参考信号资源包括每一个参考信号资源组中的一个参考信号资源。也就是说，针对每个参考信号资源组，终端设备上报一个参考信号资源对应的波束的相关信息。
可选地，该至少两个参考信号资源的个数可以大于至少两个参考信号资源组的个数，这种情况下，该至少两个参考信号资源是由每一个参考信号资源组中的一个或多个参考信 号资源构成。也就是说，针对每个参考信号资源组，终端设备上报一个或多个参考信号资源对应的波束的相关信息。
需要说明的是，本申请实施例中，终端设备具有同时接收该至少两个波束发送的参考信号的能力。在实际应用中，网络设备可以通过该至少两个波束同时发送参考信号，也可以是先后发送参考信号，也就是说，终端设备可以同时接收该至少两个波束发送的参考信号，也可以是先后接收该至少两个波束发送的参考信号，终端设备可能通过同一个接收波束接收所述至少两个波束发送的参考信号，也可能通过可同时存在的至少两个接收波束同时接收所述至少两个波束发送的参考信号，具体终端设备如何判定具有上述能力为终端设备实现，不申请实施例并不限定。
可选地，在一种实现方式中，本申请实施例中的至少两个波束的相关信息包括上述至少两个参考信号接收功率以及与所述至少两个参考信号接收功率一一对应的所述至少两个参考信号资源的标识。
应理解，本申请实施例中，波束的相关信息可以具有多种可能的形式，只要该波束的相关信息能够实现指示终端设备选择上报上述至少两个波束即可，本申请实施例并不限于上述参考信号接收功率及参考信号资源的标识。例如，至少两个波束的相关信息还可以是该至少两个波束发送的参考信号的信噪比等。
应理解，本申请实施例中，第一信息可以具有多种可能的实现方式，本申请实施例并不对此做具体限定，只要该第一信息能够配置至少两个参考信号资源组即可。
下面作为实例而非限定，将分情况结合具体地例子进行对本申请的第一信息进行详细说明。
情况一：
所述参考信号资源组为参考信号资源集合，其中，所述第一信息通过直接配置、激活或触发至少两个参考信号资源集合来配置所述至少两个参考信号资源组。
可选地，所述第一信息携带在以下至少一个信令中：
无线资源控制RRC信令、媒体接入控制控制元素MAC-CE和下行控制信息DCI。
应理解，该第一信息可以携带在上述的任一个信令中，也可以携带在上述的多个信令中，本申请实施例并不限于此。
例如，在一种实现方式中，该第一信息携带在上述多个信令中。举例而言，假设，第一信息可以包括第一子信息和第二子信息，该第一子信息用于配置多组参考信号资源组，例如，该第一子信息通过配置至少两个参考信号资源集合来配置多个参考信号资源组，该第一子信息可以携带在上述一个信令中，例如，携带在RRC信令中，该第二子信息可以用于从上述第一子信息配置的多组参考信号资源组中激活或触发一组或多组资源，该第二子信息可以携带在上述另一个信令中，例如，携带在DCI中。
例如，该第一子信息用于配置3个参考信号资源组：参考信号资源组#1、参考信号资源组#2和参考信号资源组#3，具体地，该第一子信息可以通过配置3个参考信号资源集合来配置该3个参考信号资源组，例如，第一子信息用于配置resource set#1、resource set#2和resource set#3，其中，resource set#1即作为参考信号资源组#1，resource set#2即作为参考信号资源组#2，resource set#3即作为参考信号资源组#3。该第二子信息可以用于从上述3个参考信号资源组中激活或触发一个或多个参考信号资源组，例如，该第二子信息用于 激活或触发参考信号资源组#1和参考信号资源组#2。
作为示例，而非限定，下面结合表1介绍情况一中该第一信息携带在上述一个信令中的情况。
应理解，在本申请实施例中，一个资源配置(resource setting)中的资源类型(resource type)可以被配置为周期(periodic)、半持续(semi-persistent)和非周期(aperiodic)三种时域周期行为。针对该三种周期行为，网络设备可以一次激活或触发至少两个参考信号资源集实现配置至少两个参考信号资源。
应理解，本申请实施例中，“直接配置”至少两个参考信号资源集合，可以表示终端设备在接收到RRC配置消息时直接激活资源配置关联的全部resource set。
具体地，如表1中第二行所示，所述第一信息可以携带在RRC中，例如，一个关联有多个resource set的resource setting可以通过RRC配置给终端设备，即resource set的数量大于1，这种情况下，无特殊激活指令，终端设备收到RRC配置消息时直接配置(也可以称为直接激活)这个resource setting所关联的的全部resource set，而每一个被激活的resource set中的参考信号资源便组成一个参考信号资源组。
例如，该resource setting包含的多个resource set为resource set#1和resource set#2，那么终端设备在获取到该第一消息后，即可确认resource set#1对应一个参考信号资源组，例如，参考信号资源组#1，resource set#2对应一个参考信号资源组，例如，参考信号资源组#2。换句话说，终端设备在获取第一消息后，即将resource set#1作为参考信号资源组#1，将resource set#2作为参考信号资源组#2。
此时资源配置(resource setting)中的资源类型(resource type)可以被配置为周期(periodic)，即所述参考信号的发送方式可以为周期方式。
在另一种实现方式中，如表1中第三行所示，所述第一信息可以携带在MAC-CE中，此时，该resource setting同样包含多个resource set，即resource set的数量大于1，这种情况下，MAC-CE信令可以从所述resource setting所包含的多个resource set中激活至少两个resource set，而每一个被激活的resource set中的参考信号资源便组成一个参考信号资源组。
例如，该resource setting包含的多个resource set为resource set#1、resource set#2和resource set#3共三个参考信号资源集合，终端设备获取到的MAC-CE信令从该三个参考信号资源集合中激活resource set#1和resource set#2，那么终端设备即可确定resource set#1对应一个参考信号资源组，例如，参考信号资源组#1，resource set#2对应一个参考信号资源组，例如，参考信号资源组#2。换句话说，终端设备在获取第一消息后，即将resource set#1作为参考信号资源组#1，将resource set#2作为参考信号资源组#2。
此时资源配置(resource setting)中的资源类型(resource type)可以被配置为半持续(semi-persistent)，即所述参考信号的发送方式可以为半持续方式。
在另一种实现方式中，如表1中第四行所示，所述第一信息可以携带在DCI中，此时，该resource setting同样包含多个resource set，即Resource set的数量大于1，这种情况下，DCI可以从所述resource setting所包含的多个resource set中触发至少两个resource set，而每一个被触发的resource set中的参考信号资源便成为一个参考信号资源组。
例如，该resource setting包含的多个resource set为resource set#1、resource set#2和 resource set#3共三个参考信号资源集合，终端设备获取到的DCI从该三个参考信号资源集合中触发resource set#2和resource set#3，那么终端设备即可确定resource set#2对应一个参考信号资源组，例如，参考信号资源组#1，resource set#3对应一个参考信号资源组，例如，参考信号资源组#2。换句话说，终端设备在获取第一消息后，即将resource set#2作为参考信号资源组#1，将resource set#3作为参考信号资源组#2。
此时资源配置(resource setting)中的资源类型(resource type)可以被配置为非周期(aperiodic)，即所述参考信号的发送方式可以为非周期方式
应理解，本实施例所述参考信号资源组#1、#2、#3仅为举例方便理解，本实施例所述方法在具体实现时，参考信号资源组和参考信号资源集合可以理解为同一个概念。
表1
Figure PCTCN2019119186-appb-000001
应理解，表1中描述了在第一信息携带在RRC、MACE-CE和DCI中时，所述参考信号的发送方式分别为周期方式、半持续方式和非周期方式的例子。但本申请实施例并不限于此，在实际应用中，携带第一信息的信令可以与参考信号的发送周期方式任意组合，例如，在第一信息携带在RRC中时，参考信号的发送方式可以为半持续方式或非周期方式。
无论是哪一种时域周期行为，如果对某一个resource setting而言，同一时刻只有一个与之关联的resource set所包含的参考信号被激活/触发传输，那么便无法较好的实现CoMP系统中的波束训练。
而本申请实施例通过表1所示的配置方法，能够实现对资源分组，即对某一个resource setting而言，同一时刻可以有多个与之关联的resource set所包含的参考信号被激活/触发传输，而每一个被激活/触发的resource set中的参考信号资源便成为一个参考信号资源组。因此，本申请实施例中，通过网络设备一次激活/触发多个resource set，实现参考信号资源分组，并针对每个资源组上报至少一个波束的相关信息来实现与该资源组对应的网络设备的波束训练的目的。
在本申请实施例中，终端设备接收到上述的第一信息，即可确定配置的多个参考信号资源组，进而终端设备可以按照上述步骤520的方式发送上报信息。以上报信息包括的至 少两个波束的相关信息为至少两个参考信号接收功率以及与该至少两个参考信号接收功率一一对应的所述至少两个参考信号资源的标识，举例而言，终端设备确定当与一个resource setting关联的多个resource set被直接配置全部激活，或被一个MAC-CE激活信令激活，或者被一个DCI触发指令触发时，终端设备设置上报的CSI中包含的参考信号资源标识(例如，CRI、SSB index)必须来自于不同的resource set中的参考信号资源，以实现多个网络设备的波束训练。
情况二：
所述第一信息包括同一个参考信号资源集合中参考信号资源的QCL配置信息，其中，具有相同QCL配置信息的参考信号资源被配置为同一参考信号资源组。
具体而言，在情况二中，网络设备首先为终端设备配置了一个参考信号资源集合
(resource set)，例如，可以按照现有方式配置该参考信号资源集合。其中，该resource set中每一个参考信号资源都可以关联一个QCL配置信息(qcl info)。
应理解，该QCL-info可以为与参考信号资源一一对应的TCI状态标识(TCI state ID)。下文中以QCL-info为TCI state ID举例进行说明，但本申请实施例并不限于此。
应理解，在本实施例所述方法中，TCI State ID可以作为参考信号资源分组标识而非波束指示信息。
也就是说，本申请实施例可以复用现有的TCI State ID进行参考信号资源分组。
可选地，上述复用的方法可以仅在部分场景(例如，下文中的特定场景)下生效，具体地，上述复用的方法生效的场景可以参见下文中的描述，例如，为满足下文中条件一至条件四中的一个或多个条件的场景，此处不再赘述。
因此，本申请实施例通过复用已有的TCI State ID用于对参考信号资源分组，能够降低资源分组的实现复杂度。
可选地，所述第一信息携带在以下至少一个信令中：
无线资源控制RRC信令、媒体接入控制控制元素MAC-CE和下行控制信息DCI。
例如，在一种实现方式中，该第一信息携带在上述多个信令中。举例而言，假设，第一信息可以包括第一子信息和第二子信息，该第一子信息用于配置同一resource set中的参考信号资源对应的多个TCI state ID序列，该第一子信息可以携带在上述一个信令中，例如，携带在RRC信令中，该第二子信息可以用于从上述多个序列中选择其中一个序列，该第二子信息可以携带在上述另一个信令中，例如，携带在DCI中。
举例而言，resource set中包括6个参考信号资源，第一信息配置多个TCI state ID序列，其中，每一个TCI state ID序列包括6个TCI state ID。假设第一子信息可以配置5个TCI state ID序列。具体地，该5个序列每一个序列分别包括resource#1-6对应的6个TCI state ID。例如，该5个序列如下：
序列一：resource#1-6对应的6个TCI state ID分别为TCI state ID#1、1、1、1、2、2。
序列二：resource#1-6对应的6个TCI state ID分别为TCI state ID#1、2、1、1、2、2。
序列三：resource#1-6对应的6个TCI state ID分别为TCI state ID#1、1、1、1、1、2。
序列四：resource#1-6对应的6个TCI state ID分别为TCI state ID#1、1、2、1、2、1。
序列五：resource#1-6对应的6个TCI state ID分别为TCI state ID#2、1、1、1、2、2。
该第二子信息用于从多个序列中选择其中一个序列，例如，该第二子信息为3个比特， 该3个比特可以指示上述五个序列中的一个序列号。例如，该第二子信息指示的序列号为5，那么，该6个resource的分组情况为resource#1、5和6(对应的TCI state ID均为#2)为一个参考信号资源组，resource号#2、3和4(对应的TCI state ID均为#1)为另一个参考信号资源组。
应理解，该第二子信息的比特数与第一子信息配置的序列个数对应，只要第二子信息能够指示该多个序列中的任意一个序列即可，本申请实施例并不做具体限定。
作为示例，而非限定，下面结合表2介绍情况二中该第一信息携带在一个信令中的情况。
应理解，在本申请实施例中，一个资源配置(resource setting)中的资源类型(resource type)可以被配置为周期(periodic)、半持续(semi-persistent)和非周期(aperiodic)三种时域周期行为。
具体地，如表2中第二行所示，所述第一信息可以携带在RRC中，例如，一个resource set包含多个NZP-CSI-RS resource，该第一信息可以配置在NZP-CSI-RS-Resource的配置信息中，即第一信息可以是NZP-CSI-RS-Resource的一个参数域。例如，NZP-CSI-RS resource的配置信息包含一项TCI state ID，这种情况下，终端设备收到所述参考信号资源的配置信息，即可将该resource set中配置有相同TCI state ID的参考信号资源确定为同一参考信号资源组。
应理解，本申请实施例中，resource set中的包括的参考信号资源可以是零功率参考信号资源或非零功率参考信号资源，该参考信号可以是CSI-RS、SSB或SRS等，表2中仅以resource set包含NZP-CSI-RS resource为例进行说明，但本申请实施例并不限于此。
例如，在一种实现方式中，第一信息也可以配置在零功率信道状态信息参考信号
ZP-CSI-RS resource的的配置信息中，即第一信息可以是配置ZP-CSI-RS resource的一个参数域，本申请实施例并不限于此。
例如，一个resource set共包括resource#1至resource#8，其中，resource#1至resource#4对应的TCI state ID为TCI state ID#1，resource#5至resource#8对应的TCI state ID为TCI state ID#2，那么终端设备在接收到携带第一信息的RRC消息后，即可确定resource set#1至resource#4对应同一参考信号资源组，例如，参考信号资源组#1；resource set#5至resource#8对应同一参考信号资源组，例如，参考信号资源组#2。
此时该resource set所关联的资源配置(resource setting)中的资源类型(resource type)可以被配置为周期(periodic)，即所述参考信号的发送方式可以为周期方式。
在另一种实施方式中，如表2中的第三行所示，所述第一信息可以携带在MAC-CE中，例如，一个resource set包含多个NZP-CSI-RS resource，该第一信息可以为关联该resource set的MAC-CE激活信令中一组参数，例如，一组TCI state ID组成的序列，其中TCI state ID的数量与该resource set中所包含的NZP-CSI-RS resource的数量相等，即按照先后顺序，该组TCI state ID与NZP-CSI-RS resource一一对应。这种情况下，终端设备收到MAC-CE消息后，可以将相同TCI state ID所对应的参考信号资源确定为同一参考信号资源组。
例如，情况二中的resource set共包括resource#1至resource#8，而与该resource set关联的MAC-CE激活信令中的TCI state ID序列包括8个TCI state ID，其中，前4个TCI  state ID为#1，后4个TCI state ID为#2，因此，resource#1至resource#4对应的TCI state ID为TCI state ID#1，resource#5至resource#8对应的TCI state ID为TCI state ID#2，那么终端设备在接收到携带第一信息的MAC-CE信令后，即可确定resource set#1至resource#4对应同一参考信号资源组，例如，参考信号资源组#1；resource set#5至resource#8对应同一参考信号资源组，例如，参考信号资源组#2。
此时该resource set所关联的资源配置(resource setting)中的资源类型(resource type)可以被配置为半持续(semi-persistent)，即所述参考信号的发送方式为半持续方式。
在另一种实施方式中，如表2中的第四行所示，所述第一信息可以携带在DCI中，例如，一个resource set包含多个NZP-CSI-RS resource，该第一信息可以为关联该resource set的DCI触发信令中一组参数，例如，一组TCI state ID组成的序列，其中TCI state ID的数量与该resource set中所包含的NZP-CSI-RS resource的数量相等，即按照先后顺序，该组TCI state ID与NZP-CSI-RS resource一一对应。这种情况下，终端设备收到DCI消息后，可以将相同TCI state ID所对应的参考信号资源确定为同一参考信号资源组。
例如，情况二中的resource set共包括resource#1至resource#8，而与该resource set关联的DCI触发信令中的TCI state ID序列包括8个TCI state ID，其中，第1、3、5、7个TCI state ID为#1，剩余第2、4、6、8个TCI state ID为#2，因此，resource#1、#3、#5、#7对应的TCI state ID为TCI state ID#1，resource#2、#4、#6、#8对应的TCI state ID为TCI state ID#2，那么终端设备在接收到携带第一信息的DCI后，即可确定resource set#1、#3、#5、#7对应同一参考信号资源组，例如，参考信号资源组#1；resource set2、#4、#6、#8对应同一参考信号资源组，例如，参考信号资源组#2。
此时该resource set所关联的资源配置(resource setting)中的资源类型(resource type)可以被配置为非周期(aperiodic)。

Figure PCTCN2019119186-appb-000002
终端设备接收到上述情况二中的第一信息后，即可确定配置的多个参考信号资源组，进而终端设备可以按照520的方式发送上报信息。具体地，终端设备首先根据TCI state ID确定同一resource set中的多个参考信号资源组，然后，终端设备设置上报的CSI中包含的参考信号资源标识(例如，CRI、SSB index)必须来自于不同的参考信号资源组，以实现多个网络设备的波束训练。
本申请实施例通过将具有相同QCL配置信息的参考信号资源配置为同一参考信号资源组，实现了配置上述至少两个参考信号资源组，由于不同的网络设备对应不同的参考信 号资源组，针对每个参考信号资源组终端设备上报其对应的一个或多个波束的相关信息，进而本申请实施例实现了对联合传输的多个网络设备的下行波束同时训练的目的。
情况三：
所述第一信息为资源配置信息，所述资源配置信息通过配置同一个参考信号资源集合中参考信号资源的标识序号实现对至少两个参考信号资源组的配置。
例如，该第一信息为资源配置(resource setting)信息，具体地，该第一信息可以通过配置同一resource set中的参考信号资源的标识序号实现对至少两个参考信号资源组的配置。
可选地，所述第一信息携带在以下至少一个信令中：
无线资源控制RRC信令、媒体接入控制控制元素MAC-CE和下行控制信息DCI。
在一种实现方式中，该第一信息携带在上述多个信令中。举例而言，假设，第一信息可以包括第一子信息和第二子信息，例如，该第一子信息用于指示多个分组规则，其中，每一个分组规则包括参考信号资源组与参考信号资源的表示序号的关系。该第二子信息用于选择第一子信息指示的多个分组规则中的一个分组规则。
举例而言，假设同一参考信号资源集中的参考信号资源的标识序号为1至8，以及10至16；该第一子信息用于指示2个分组规则，例如，分组规则一为同一参考信号资源集合中参考信号资源标识序号连续的参考信号资源属于同一个参考信号资源组；分组规则二位同一参考信号资源集合中参考信号资源标识序号为偶数的参考信号资源属于同一个参考信号资源组，参考信号资源标识序号为奇数的参考信号资源属于另一个参考信号资源组。该第二子信息例如可以指示其中一个分组规则的标识。例如，该第二子信息指示分组规则的标识为1，那么终端设备根据该第一子信息和该第二子信息可以确定序号为1至8的参考信号资源属于一个参考信号资源组，序号为10-16的参考信号资源为另一参考信号资源组。
可选地，在另一种实现方式中，所述第一信息也可以携带上述一个信令中，例如，携带在RRC中，本申请实施例并不限于此。
作为示例而非限定，下面以第一信息为资源配置(resource setting)信息携带在RRC中为例，结合具体地例子介绍本申请情况三中多波束分组上报的方法。
例如，本申请实施例中，可以采用预定的规则来根据参考信号资源的标识序号确定参考信号资源组。
具体地，该预定规则可以为：同一参考信号资源集合中参考信号资源标识序号连续的参考信号资源属于同一个参考信号资源组。
例如，第一信息配置的参考信号资源标识序号为1至8，以及10至16，那么按照上述预设规则，序号为1至8的参考信号资源属于一个参考信号资源组，序号为10-16的参考信号资源为另一参考信号资源组。
或者，该预定规则可以为：参考信号资源标识序号为奇数的参考信号资源为一个参考信号资源组，参考信号资源标识序号为偶数的参考信号资源为另一个参考信号资源组。
例如，第一信息配置的参考信号资源标识序号为1至8，以及10至16，那么按照上述预设规则，序号为1、3、5、7、11、13和15的参考信号资源属于一个参考信号资源组，序号为2、4、6、8、10、12、14和16的参考信号资源属于另一个参考信号资源组，
或者，该预定规则为：参考信号资源标识序号大于序号平均值/中间值的参考信号资源为一个参考信号资源组，参考信号资源标识序号小于序号平均值/中间值的参考信号资源为另一个参考信号资源组。
例如，第一信息配置的参考信号资源标识序号为1至8，以及10至16，那么按照上述预设规则：参考信号资源标识序号大于序号平均值的参考信号资源为一个参考信号资源组，参考信号资源标识序号小于序号平均值的参考信号资源为另一个参考信号资源组。由于该平均值＝(1+2..+8+10+…+16)/15＝8.47，那么由于序号1至8均小于8.47，序号10至16均大于8.47，因此，序号为1至8的参考信号资源属于一个参考信号资源组，序号为10-16的参考信号资源为另一参考信号资源组。
需要说明的是，在参考信号资源标识序号等于平均值/中间值时，该参考信号资源标识序号对应的参考信号资源可以属于序号小于平均值/中间值的一个参考信号资源组，或者，属于序号大于平均值/中间值的一个参考信号资源组，本申请对此不做限定。
例如，第一信息配置的参考信号资源标识序号为1至8，以及10至16，那么按照上述预设规则：参考信号资源标识序号大于序号中间值的参考信号资源为一个参考信号资源组，参考信号资源标识序号小于序号中值的参考信号资源为另一个参考信号资源组。由于1至8，以及10至16共15个序号的中间值为8，由于序号1至7均小于8，序号10至16均大于8，因此，序号为1至7的参考信号资源属于一个参考信号资源组，序号为10-16的参考信号资源为另一参考信号资源组。由于，参考信号资源标识序号为8等于中间值，假设参考信号资源标识序号等于中间值时对应的参考信号资源可以属于序号小于中间值的参考信号资源组，那么，最终可以划分序号为1至8的参考信号资源属于一个参考信号资源组，序号为10-16的参考信号资源为另一参考信号资源组。
应理解，上述多个参考信号资源标识序号为奇数时，上述中间值即为参考信号资源标识序号由小到大(或由大到小)排序最中间一个位置的序号值，在上述多个参考资源标识序号为偶数时，上述中间值即为参考信号资源标识序号由小到大(或由大到小)排序最中间两个位置所对应的两个序号的平均值，或者为排序最中间两个位置对应的两个序号的较大值或较小值，本申请实施例并不限于此。
终端设备接收到上述的第一信息，即可确定配置的多个参考信号资源组，进而终端设备可以按照520的方式发送上报信息。具体地，首先，终端设备可以根据为资源配置信息配置的参考信号资源标识确定多个参考信号资源组，然后终端设备设置上报的CSI中包含的参考信号资源标识(例如，CRI、SSB index)必须来自于不同的参考信号资源组，以实现多个网络设备的波束训练。
本申请实施例通过将参考信号资源序号满足规则的参考信号资源划分为同一参考信号资源组，实现了配置上述至少两个参考信号资源组，由于不同的网络设备对应不同的参考信号资源组，针对每个参考信号资源组终端设备上报其对应的一个或多个波束的相关信息，进而本申请实施例实现了对联合传输的多个网络设备的下行波束同时训练的目的。
应理解，本申请实施例中，终端设备可以在收到第一信息后，即可按照上述情况一、情况二或者情况三实施例的方式(以下称为多波束分组上报模式)发送上报信息。可选地，本申请实施例中还可以是在特定场景下，即在满足一定的条件下，按照上述多波束分组上报模式发送上报信息。
例如，终端设备可以在收到第一信息后，且判断在满足预定条件的情况下，按照上述方式发送上报信息。
具体地，该预设条件包括以下条件中的至少一种：
条件一：上报配置(reporting setting)信息中的上报参数包括波束扫描相关参数，例如，该波束扫描相关参数包括CRI和RSRP。
条件一把本申请实施例分组上报方式限制在波束扫描相关的测量与上报场景下。
条件二：资源配置(resource setting)信息中的重复参数(repetition)取值为预设值，例如，该预设值为关闭(OFF)状态。
该预设值为关闭状态可以理解为当前执行的是发送波束扫描。
条件二将本申请实施例分组上报方式限制在发送波束扫描的场景下，应理解，条件二中所述重复参数的预设值也可以为开启(ON)状态，本发明实施例并未对其具体的取值做限定。
条件三：资源配置信息配置的资源类型为预设资源类型，所述预设资源类型为周期性资源、非周期资源或半持续资源。
通过条件三，可以将本申请实施例所述方法限制在某一种或几种时域周期行为的参考信号发送场景下。例如，当且仅当CSI-RS通过非周期方式发送时，才可以应用本申请实施例分组上报方式发送上报信息，此时，该多个参考信号资源组，即参考信号资源集合是通过DCI信令触发的。或者，当且仅当CSI-RS通过半持续方式发送时，才可以应用本申请实施例分组上报方式发送上报信息，此时，该多个参考信号资源组，即参考信号资源集合是通过MAC-CE信令激活的。或者，当且仅当CSI-RS通过周期方式发送时，才可以应用本申请实施例分组上报方式发送上报信息，此时，该多个参考信号资源组，即参考信号资源集合是通过RRC信令配置的。或者，以上任意两种情况的组合。
条件四：上报配置(reporting setting)信息中的第一参数取值为第一值，其中，所述第一参数取值为第一值表示所述终端设备支持同时接收至少两个波束。
条件四结合现有技术中的分组上报方法，将参考信号资源分组的方法限制在分组上报开启的场景下。例如，该第一参数为基于组的波束报告(group based beam reporting)，该第一值表示开启状态。具体地，基于组的波束报告(group based beam reporting)为开启状态表示终端设备具有同时接收多个波束的能力。应理解，在第一参数为关闭状态时可以表示终端设备不支持接收上述多个波束的能力。
应理解，该预设条件可以包括上述四个条件中的任意一个，也可以包括上述四个条件中的多个条件，例如，包括上述四个条件中的任意两个条件、任意三个条件或全部条件。也就说，在该多个条件同时满足的情况下，终端设备才在收到第一指示信息后，发送上述上报信息，即终端设备在设置上报的CSI中包含的参考信号资源标识(CRI、SSB index)必须来自于不同的参考信号资源组。
应理解，本申请实施例中仅是示例性的描述了上报信息包括CSI中的参考信号资源标识(例如，CRI、SSB index)的例子，在实际应用中，该上报信息可以还可以包括参考信号接收功率等其他参数，本申请实施例并不限于此。
本申请实施例通过在满足一定的条件下，终端设备才按照上述多波束分组上报的方法发送上报信息，能够将多波束分组上报的方法限定在波束训练的场景下，避免了其他场景 下采用此方法发送上报信息的情况。
前文结合图5描述了终端设备收到第一信息后，在上述限定的条件成立的情况下，终端设备即可默认上文中的情况一、情况二或情况三的多波束分组上报模式发送多个波束的相关信息的具体例子。也就是说，网络设备无需通过显示信令通知终端设备是否采用上述多波束分组上报模式上报信息，终端设备自身在判断满足条件的情况下，即可采用上述多波束分组上报模式上报信息。可选地，在实际应用中，本申请实施例中还可以通过网络设备发送显示的信令通知终端设备是否按照上述图5的多波束分组上报模式发送上报信息。
具体地，在图5的基础上，在步骤520之前，该方法还可以包括：所述网络设备向所述终端设备发送指示信息，所述指示信息用于指示多波束分组上报模式为开启状态，其中，所述多波束分组上报模式为开启状态表示所述终端设备需要上报所述至少两个波束的相关信息，其中，所述至少两个波束用于发送承载在至少两个参考信号资源上的参考信号，所述至少两个波束发送的参考信号能够被所述终端设备同时接收，所述至少两个参考信号资源分别来自于所述至少两个参考信号资源组。
可选地，当该指示信息指示多波束分组上报模式为关闭状态时，终端设备可以不按照上述规定发送需要上报的信息，例如，终端设备上报的信息可以是来自于同一个TRP的波束对应的相关信息。例如，假设两个TRP到终端设备的波束质量相差过大，不宜强制要求数据协作时，网络侧设备可以通过该指示信息指示多波束分组上报模式为关闭状态，这种情况下，网络设备可以调度同一个TRP的多个波束为该UE服务，相应的，在波束训练时，终端设备可以上报同一TRP的多个波束的相关信息。
所述指示信息可以通过RRC信令配置，更进一步的，通过上报配置(reporting setting)信息发送给终端设备。
需要说明的是，前文结合图5描述了终端设备发送来自于至少两个参考信号组的波束的相关信息的例子。
可替代地，在一种可能的实现方式(以下称为带有优先级的多波束分组上报模式)中，终端设备可能没有找到同时满足以下两个条件的波束，条件1：来自两个参考信号资源组，条件2：终端设备能够同时接收的多个波束。
这种情况下，本申请实施例可以设置该两个条件的优先级，例如，优先上报满足条件1，或者，优先上报满足条件2的波束的相关信息。例如，该优先级是条件2优先于条件1。即如果没有同时满足条件2和条件1的波束组合，则终端设备选择满足条件2的波束组合进行上报。
这个优先级可以作为一项配置信息由网络设备配置给终端设备，该配置信息可以通过RRC，MAC-CE或DCI下发给终端设备。例如，网络设备通过RRC信令配置了带有优先级的多波束分组上报模式开启的指示信息，然后可以通过DCI下发优先级配置信息，这样便可以灵活的根据后续数据调度的需求来获得相应的波束上报信息。实际应用中，如果网络设备有比较迫切的多波束传输的需求，便可以将条件2的优先级设为高于条件1，此时当终端设备无法找到同时满足条件1和2的波束时，便选择上报满足条件2的波束，由于网络设备知道每个波束标识(或对应的参考信号资源)隶属于哪一个参考信号资源组，所以网络设备同样可以根据上报的波束ID获知，本次上报的多个波束是否来自于同一个TRP。反之，如果网络设备希望尽量的获知不同TRP的波束质量信息，便可以将条件1 的优先级设为高于条件2，这种情况下网络设备便不可以假设本次上报获得的多个波束可以被终端设备同时接收。
可选的，假设UE即便找到了同时满足上述条件1和条件2的波束组合，但该两个波束之间的RSRP差值很大，在实际应用中，下行传输时该波束组合可能根本不会被调度。因此，本申请实施例中，还可以设置一个RSRP阈值，当波束组合中的波束的RSRP差值大于这个RSRP阈值时，终端设备认为这些波束组合不满足实际传输所需，这种情况下，终端设备即便找到了同时满足条件1和条件2的波束组合，也不会将这些波束上报，而是选择满足RSRP阈值和优先级较高的条件的波束组合进行上报。。
应理解，上文中图1至图5的例子，仅仅是为了帮助本领域技术人员理解本申请实施例，而非要将本申请实施例限于所例示的具体数值或具体场景。本领域技术人员根据所给出的图1至图5的例子，显然可以进行各种等价的修改或变化，例如，本领域技术人员可以根据图1至图5的例子，将多个实施例进行组合拆分等，本申请实施例这样的修改或变化也落入本申请实施例的范围内。
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。
上文中，结合图1至图5详细描述了本申请实施例的方法，下面结合图6至图9描述本申请实施例的通信装置。

处理单元72可用于执行该存储器存储的指令，以控制收发单元71接收信号和/或发送信号，完成上述方法实施例中终端设备的功能。作为一种实现方式，收发单元71的功能可以考虑通过收发电路或者收发的专用芯片实现。
应理解，图7所示的终端设备700能够实现图5方法实施例中涉及终端设备的各个过程。终端设备700中的各个模块的操作和/或功能，分别为了实现上述方法实施例中的相应流程。具体可参见上述方法实施例中的描述，为避免重复，此处适当省略详述描述。
