具体实施方式
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。
参见图1，图1是本公开实施例提供的一种测量方法的流程图，用于网络设备，如图1所示，方法包括以下步骤：
步骤101：所述网络设备为中继设备和/或终端设备配置N个参考信号，N为大于1的整数，所述N个参考信号用于确定至少一个目标参考信号索引，所述至少一个目标参考信号索引对应的参考信号属于所述N个参考信号；
其中，网络设备和中继设备中任意之一采用固定空间滤波方式或固定空间传输参数进行N个参考信号的传输，至少一个目标参考信号索引用于终端设备向网络设备上报；或者，网络设备和中继设备两者均采用固定空间滤波方式或者固定空间传输参数进行N个参考信号的传输，终端设备不向网络设备上报至少一个目标参考信号索引。
其中，网络设备向中继设备发送N个参考信号，N为大于1的整数，以使得中继设备向终端设备转发N个参考信号，N个参考信号用于终端设备进行测量确定至少一个目标参考信号索引，至少一个目标参考信号索引对应的参考信号属于N个参考信号。
可以理解，中继设备接收网络设备配置的N个参考信号后，可将其转发给终端设备，终端设备接收N个参考信号，对N个参考信号进行测量以得到至少一个目标参考信号索引。作为一个示例，中继设备可对N个参考信号进行放大，以增强信号，将放大后的N个参考信号发送给终端设备，提高信号传输性能，终端设备接收放大后的N个参考信号后，可基于放大后的N个参考信号进行空间滤波方式或空间传输参数测量确定目标空间滤波方式或空间传输参数，可提高空间滤波方式或空间传输参数测量的准确性。作为一个示例，上述参考信号可以是CSI-RS(Channel State Information Reference Signal，信道状态信息参考信号)等。
需要说明的是，空间滤波方式(也可以称为空间传输滤波方式或空间收/ 发滤波方式，即spatial domain transmission filter)和空间传输参数(也可以称为空间收/发参数，即Spatial Tx/Rx parameter)均是与波束对应，可以理解波束、空间滤波方式以及空间传输参数表示相同的含义，即三者可相互替代。上述网络设备和中继设备中任意一者采用固定空间滤波方式或固定空间传输参数进行N个参考信号的传输，即另一者采用变化的空间滤波方式(N个空间滤波方式)或变化的空间传输参数(N个空间传输参数)进行N个参考信号的传输，则终端设备接收N个参考信号后进行测量得到至少一个目标参考信号索引后，可将至少一个目标参考信号索引上报给网络设备，若网络设备和中继设备中两者均采用固定空间滤波方式或空间传输参数进行参考信号传输，则终端设备接收N个参考信号后进行测量得到至少一个目标参考信号索引后，至少一个目标参考信号索引保留在终端设备，不上报给网络设备，如此，可根据网络设备和中继设备传输参考信号的采用的空间滤波方式或空间传输参数的情况确定是否上报目标参考信号索引，可提高参考信号索引上报的灵活性。作为一个示例，对于网络设备和中继设备，参考信号传输可以理解为参考信号发送，对于终端设备，参考信号传输可以理解为参考信号接收。

下面以一个具体实施例对上述方法的过程加以具体说明。以网络设备为gNB(5G基站)、中继设备为Smart repeater(智能中继设备)以及终端设备为UE(用户设备)为例进行说明。空间滤波方式、空间传输参数和波束三者可以相互替代，在本实施例中，以波束为例进行说明。
对于FR2频段的Smart repeater来说，先考虑下行的波束管理，其在转发下行信号的时候一方面要知道使用哪个接收波束接收gNB的发送的下行信号，另一方面需要决策用哪个发送波束对接收到的下行信号进行转发。对于前者，如果Smart repeater具备一个普通UE的功能，它可以复用现有的UE下行波束管理的流程来确定接收gNB下行信号的接收波束；对于后者，需要Smart repeater配合基站和UE进行波束测量和上报，从而gNB可以为Smart repeater提供空间相关信息/波束相关信息的指示信息，来指示Smart repeater采用哪个发送波束对接收到的下行信号进行转发等。
在不存在Smart repeater时，当gNB与一个普通UE通信时，可以通过现有的波束测量和上报机制让基站知道下行使用基站的哪个发送波束发送性能最好，现有的波束测量和上报机制包括发送波束测量和接收波束测量：
发送波束测量：基站变化发送波束，UE固定接收波束。基站配置N个参考信号，对应N个候选的发送波束，基站通知UE有N个参考信号对应不同发送波束的测量；UE用固定接收波束接收和测量所有的N个参考信号，选择最合适发送波束上报给基站。
接收波束测量：UE变化接收波束，并假设基站固定发送波束。基站用相同的波束发送N个参考信号，并指示UE采用变化接收波束测量的方式来确定最佳的接收波束。UE所确定的最佳接收波束可不上报给基站，而是存在UE中。
然而，如图4所示，当存在Smart repeater时，当gNB与一个普通UE通信时，即使基站使用一个固定波束，当Smart repeater使用不同波束进行下行信号的转发时，UE的接收信号质量也是不一样的。因此需要增强现有的波束测量和上报机制来更有效的支持存在Smart repeater的场景，提高波束测量效果。
一个实施例中，gNB固定发送波束，用相同的发送波束发送N个参考信号；基站指示Smart repeater采用N个不同的发送波束对这N个参考信号进行放大转发(例如通过轮询的方式变化波束)，如图5所示。UE用固定接收波束接收和测量所有的N个参考信号，选择最合适发送波束(对应至少一个目标参考信号索引)上报给基站。
在本实施例中，对于Smart repeater，基站为Smart repeater配置一个用于波束管理的NZP-CSI-RS-ResourceSet，例如，可通过一个高层信令(对应第一信令)为Smart repeater配置NZP-CSI-RS-ResourceSet，该高层信令中的repetition字段可设置为on(开启)，但是Smart repeater不需要确定和上报CRI，Smart repeater只需要使用N个不同的发送波束对这N个参考信号进行放大转发。对于UE，基站为UE配置一个用于波束管理的NZP-CSI-RS-ResourceSet(与给Smart repeater配置的相同)，可通过一个高层信令(对应第二信令)为UE配置NZP-CSI-RS-ResourceSet，该高层信令中的repetition字段可设置为off(关闭)，UE需要确定和上报CRI。或者，对于UE，基站为UE配置一个用于波束管理的NZP-CSI-RS-ResourceSet(与给Smart repeater配置的相同)，其高层信令中的repetition字段可设置为on，但是UE需要确定和上报CRI。
另一个实施例中，基站变化发送波束，基站配置N个参考信号，对应N个不同的发送波束，Smart repeater使用固定发送波束对这N个参考信号进行放大转发；UE用固定接收波束接收和测量所有的N个参考信号，选择最合适发送波束上报给基站，如图6所示。
对于Smart repeater，基站为Smart repeater配置一个用于波束管理的NZP-CSI-RS-ResourceSet，其高层信令中的repetition字段可设置为off，但是Smart repeater不需要确定和上报CRI,Smart repeater只需要使用固定发送波束对这N个参考信号进行放大转发。对于UE，基站为UE配置一个用于波束管理的NZP-CSI-RS-ResourceSet(与给Smart repeater配置的相同)，其高层信令中的repetition字段可设置为off，UE需要确定和上报CRI，例如，UE可将CRI上报给Smart repeater，通过Smart repeater转发给基站。
又一个实施例中，基站固定发送波束，用相同的波束发送L个参考信号； 基站指示Smart repeater使用固定波束对这L个参考信号进行放大转发；基站指示UE采用变化接收波束测量的方式来确定最佳的接收波束，UE所确定的最佳接收波束不必上报给网络,而是存在UE中。
对于Smart repeater，基站为Smart repeater配置一个用于波束管理的NZP-CSI-RS-ResourceSet，其高层信令中的repetition字段可设置为on，Smart repeater不需要确定和上报CRI,但是基站需要指示Smart repeater使用固定波束对这N个参考信号进行放大转发。对于UE，基站为UE配置一个用于波束管理的NZP-CSI-RS-ResourceSet(与给Smart repeater配置的相同)，其高层信令中的repetition字段可设置为on，UE采用变化的接收波束测量的方式来确定最佳的接收波束，可不需要上报CRI。
在上述各实施例的波束测量和上报方法，标准至少需要增强支持如下功能：
标准增强1：基站为smart repeate配置NZP-CSI-RS-ResourceSet，并且当repetition字段设置为off,可不需要上报CRI。由于现有标准中同时支持基站给终端配置NZP-CSI-RS-ResourceSet，并且当repetition字段设置为off,UE应根据支持的CRI值集确定CRI。因此，一种方法是，标准中增加一个基站给UE的指示信令，用于指示UE在被配置了NZP-CSI-RS-ResourceSet并且当repetition字段设置为off,时,UE是否需要上报CRI。例如在NZP-CSI-RS-ResourceSet或其他地方中引入一个指示信令(criReportDisabled)，取值ENUMERATED{true}。另一种方法是，当基站给Smart repeater配置NZP-CSI-RS-ResourceSet的情况下，规则为当repetition字段设置为off时，不上报CRI。而为普通UE配置了NZP-CSI-RS-ResourceSet,repetition字段设置为off。
标准增强2：基站给Smart repeater配置NZP-CSI-RS-ResourceSet，并且将repetition字段设置为on时,基站需要指示Smart repeater是采用固定发送波束进行参考信号的放大转发还是采用变化的发送波束进行参考信号的放大转发。
通过本公开，可实现更加智能的中继数据传输，并且可以有效支持FR2(毫米波)。
