具体实施方式
在下文中将结合附图对本公开的示范性实施例进行描述。为了清楚和简明起见，在说明书中并未描述实施例的所有特征。然而，应该了解，在对实施例进行实施的过程中必须做出很多特定于实施方式的设置，以便实现开发人员的具体目标，例如，符合与设备及业务相关的那些限制条件，并且这些限制条件可能会随着实施方式的不同而有所改变。此外，还应该了解，虽然开发工作有可能是非常复杂和费时的，但对得益于本公开内容的本领域技术人员来说，这种开发工作仅仅是例行的任务。
在此，还应当注意，为了避免因不必要的细节而模糊了本公开，在附图中仅仅示出了与至少根据本公开的方案密切相关的处理步骤和/或设备结构，而省略了与本公开关系不大的其他细节。
以下将参照附图来描述本公开的无线通信系统的基本技术构思以及示例性实施例。
1、示例无线通信系统与示例电子设备
图1示出了根据本公开的实施例的无线通信系统100的示意图。可以在无线通信系统100内执行本公开描述的各种技术。无线通信系统100可以包括基站110和UE 120。应理解，虽然图1中仅示出了一个基站110和三个UE 120，但是应理解，无线通信系统100还可以包括其他任意合适数量的基站和UE。
基站110是无线通信系统100中网络侧设备的示例。在本公开中，术语“基站”与“网络侧设备”可以互换地使用。可以使用任意网络侧设备来替代地实现基站110的操作。基站110可以被实现为任何类型的基站。例如，基站110可以被实现为eNB，诸如宏eNB和小eNB。小eNB可以为覆盖比宏小区小的小区的eNB，诸如微微eNB、微eNB和家庭(毫微微)eNB。又例如，基站110也可以实现为gNB，诸如宏gNB和小gNB。小gNB可以为覆盖比宏小区小的小区的gNB，诸如微微gNB、微gNB和家庭(毫微微)gNB。代替地，基站可以被实现为任何其他类型的基站，诸如NodeB和基站收发台(Base Transceiver Station，BTS)。
UE 120无线通信系统100中用户侧设备的示例。UE 120可以被实现为任何类型的终端设备。例如，UE 120可以被实现为移动终端(诸如智能电话、平板个人计算机(PC)、笔记本式PC、便携式游戏终端、便携式/加密狗型移动路由器和数字摄像装 置)或者车载终端(诸如汽车导航设备)。又例如，UE 120还可以被实现为执行机器对机器(M2M)通信的终端(也称为机器类型通信(MTC)终端)。此外，UE 120可以为安装在上述终端中的每一个终端上的无线通信模块(诸如包括单个晶片的集成电路模块)。
基站110与UE 120可以根据任何适当的通信协议来执行无线通信。例如，可以根据蜂窝通信协议来执行无线通信。蜂窝通信协议可以包括4G、5G以及任何正在开发或将要开发的蜂窝通信协议。
图2示出了根据本公开的实施例的电子设备200的框图。电子设备200可以包括通信单元210、存储单元220以及处理电路230。
通信单元210可以被用于接收或发送无线电传输。例如，该无线电传输可以包括从基站110到UE 120的下行链路传输和/或从UE 120到基站110的上行链路传输。该无线电传输可以被用于传送各种控制信令(例如无线电资源控制(RRC)、下行链路控制信息(Downlink Control Information，DCI)、上行链路控制信息(Uplink Control Information，UCI))和/或用户数据。该无线电传输也可以被用于传送一个或多个同步信号、参考信号或测量信号,例如同步信号块(Synchronization Signal Block，SSB)、信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)、探测参考信号(Sounding Reference Signal，SRS)等。通信单元210可以对所发送的无线电信号执行诸如上变频、数字-模拟转换之类的功能，和/或对所接收的无线电信号执行诸如下变频、模拟-数字变换之类的功能。在本公开的实施例中，可以使用各种技术来实现通信单元210。例如，通信单元210可以被实现为天线器件、射频电路和部分基带处理电路等通信接口部件。通信单元210用虚线绘出，因为它可以替代地位于处理电路230内或者位于电子设备200之外。
存储单元220可以存储由处理电路230产生的信息，通过通信单元210从其他设备接收的信息或将要发送到其他设备的信息，用于电子设备200操作的程序、机器代码和数据等。存储单元220可以是易失性存储器和/或非易失性存储器。例如，存储单元220可以包括但不限于随机存取存储器(RAM)、动态随机存取存储器(DRAM)、静态随机存取存储器(SRAM)、只读存储器(ROM)以及闪存存储器。存储单元220用虚线绘出，因为它可以替代地位于处理电路230内或者位于电子设备200之外。
处理电路230可以被配置为执行一个或多个操作，从而提供电子设备200的各种功能。作为示例，处理电路230可以通过执行存储单元220所存储的一个或多个可执 行指令而执行对应的操作。例如，当电子设备200被用于实现本公开所描述的基站侧的设备时，处理电路230可以被配置为执行本公开所描述的基站侧一个或多个操作。当电子设备200被用于实现本公开所描述的UE侧的设备时，处理电路230可以被配置为执行本公开所描述的UE侧的一个或多个操作。可以使用电子设备200(更具体地，处理电路230)来执行本文描述的与基站110相关的一个或多个操作。在这种情况下，电子设备200可以被实现为基站110本身、基站110的一部分、或者用于控制基站110的控制设备。例如，电子设备200可以被实现为用于控制基站110的芯片。此外，也可以使用电子设备200(更具体地，处理电路230)来执行本文描述的与UE 120相关的一个或多个操作。在这种情况下，电子设备200可以被实现为UE 120本身、UE 120的一部分、或者用于控制UE 120的控制设备。例如，电子设备200可以被实现为用于控制UE 120的芯片。
当电子设备200被实现为UE 120本身时，电子设备200的通信单元210包括多个天线面板，例如图2中所示的天线面板240-1至240-4。虽然图4中示出了四个天线面板，但应认识到，天线面板的数量可以为任意一个或多个。每个天线面板可以包括一个或多个天线单元。每个天线面板可以具有独立的收发电路，因而可以彼此独立地形成接收或发射波束。各个天线面板可以具有相同或不同的天线阵列尺寸。
应当注意的是，以上描述的各个单元是用于实施本公开中描述的处理的示例性和/或优选的模块。这些模块可以是硬件单元(诸如中央处理器、场可编程门阵列、数字信号处理器或专用集成电路等)和/或软件模块(诸如计算机可读程序)。以上并未详尽地描述用于实施下文描述各个步骤的模块。然而，只要有执行某个处理的步骤，就可以有用于实施同一处理的对应的模块或单元(由硬件和/或软件实施)。通过下文所描述的步骤以及与这些步骤对应的单元的所有组合限定的技术方案都被包括在本公开的公开内容中，只要它们构成的这些技术方案是完整并且可应用的。
此外，由各种单元构成的设备可以作为功能模块被并入到诸如计算机之类的硬件设备中。除了这些功能模块之外，计算机当然可以具有其他硬件或者软件部件。
下面将结合附图来进一步描述本公开的示例实施例。应当注意，在下面的描述中，各种在基站侧执行的方法可以由在基站侧实现的电子设备200的处理电路230执行。以下为了方便，将这种方法描述为由基站110执行。但是，本领域技术人员可以知晓，这些方法也可以由基站110的一部分执行，或者由基站110的控制设备执行。此外，各种在UE侧执行的方法可以是由在UE侧实现的电子设备200的处理电路230执行。 以下为了方便，将这种方法描述为由UE 120执行。但是，本领域技术人员可以知晓，这些方法也可以由UE 120的一部分执行，或者由UE 120的控制设备执行。
现有的波束管理和波束选择仅仅依赖于对参考信号的测量，且是在基站处完成的。在UE具有多天线面板的情况下，面板选择也称为波束管理中的一部分。UE在接收下行链路传输或发送上行链路传输时需要快速选择出合适的天线面板。而且，由于基站并不能及时获知UE处的天线面板的状态变化，会导致仅仅依赖参考信号测量而做出的选择可能并不是最合适的。需要改进的波束管理方案来解决至少一个上述问题。
2、下行参考信号与天线面板的关联
2.1关联上报
图3示出了根据本公开的实施例的方法300的示例流程图。方法300可以被用于实现根据本公开的实施例的用于下行参考信号与天线面板的关联方案。方法300可以在UE 120侧执行。方法300可以包括步骤310至步骤320。
在步骤310中，UE 120可以被配置为通过多个天线面板从基站接收一个或多个下行链路参考信号(Downlink Reference signal，DL RS)。
UE 120的天线面板可以具有不同的面板状态。在一些实施例中，面板状态可以为以下几种状态中的任意一种：(1)“未激活”；(2)“仅针对下行链路测量而部分激活”；(3)“仅针对下行链路测量和数据传输而部分激活”和(4)“完全激活”。“未激活”意味着该天线面板被关闭而无法接收/发送任何无线电信号。“仅针对下行链路测量而部分激活”意味着该天线面板不支持下行链路数据传输和上行链路发送。“仅针对下行链路测量和数据传输而部分激活”意味着该天线面板不支持上行链路发送。“完全激活”意味着该天线面板对下行链路接收和上行链路发送均支持。
UE 120可以根据设备的旋转、移动、信道阻塞、最大允许暴露量(Maximum Power Exposure，MPE)要求、功率控制等因素而改变其各个天线面板的面板状态。例如，多个天线面板可以位于UE 120设备的不同位置处。当UE 120处于第一设备姿态或位置时，处于第一位置处的天线面板可以相对于基站提供较好的波束而处于第二位置处的天线面板则无法提供较好的波束。此时，UE 120可以部分激活或完全激活(例如，打开)第一位置处的天线面板，而关闭第二位置处的天线面板。而当UE 120由于旋转或移动改变至第二设备姿态或位置时，位于第二位置处的天线面板将可以相对于基站提供较好的波束。这时，UE 120可以去激活(例如，关闭)第一位置处的天线面板， 而部分激活或完全激活处于第二位置处的天线面板。又例如，当多个天线面板同时进行上行传输而彼此间出现干扰或者与其它UE的传输发生干扰导致阻塞时，UE 120可以选择性关闭部分天线面板的上行发送功能。又例如，当UE 120靠近人体时，可以出于满足MPE要求的考虑而关闭UE中距离人体较近侧的天线面板。又例如，当UE 120电量受限时，可以为了省电而关闭或部分关闭一些天线面板。
在一些实施例中，UE 120所接收的每个DL RS可以是信道状态信息参考信号CSI-RS或同步信号块SSB。CSI-RS用于信道探测。CSI-RS和SSB都可以用于波束管理。CSI-RS可以以周期性、半持续或非周期性方式从基站发送到UE。半持续CSI-RS需要基站发送MAC控制信元(MAC CE)来激活/去激活。非周期CSI-RS需要基站通过下行控制信息DCI来触发。
在一些实施例中，UE 120所接收的DL RS可以是CSI-RS资源集，其中该CSI-RS资源集的重复参数Repetition被配置为ON。Repetition参数的值可以指示该CSI-RS资源集中的所有CSI-RS是否对应同一波束。Repetition被配置为ON值意味着该CSI-RS资源集中的所有CSI-RS对应同一波束。Repetition被配置为OFF值意味着该CSI-RS资源集中的所有CSI-RS对应不同波束。如后文将介绍的，Repetition参数被配置为ON的CSI-RS资源集在用于UE处的接收波束优化时有利的。在一些实施例中，UE 120所接收的DL RS可以是SSB资源集。
UE 120可以自行决定以何种方式使用多个天线面板来接收DL RS。典型地，UE 120使用不同的天线面板来接收每个DL RS。在其它实施例中，UE 120可以被配置为使用一个天线面板来接收多个DL RS和/或使用多个天线面板来接收一个DL RS。也就是说，天线面板与DL RS之间的映射关系会出现一对一、一对多和多对一的情形。UE 120可以基于DL RS端口数量、天线面板数量、基站发送波束宽度、天线面板接收波束宽度等各种因素来确定具体使用哪种映射关系。映射关系可以在UE的使用过程中改变。
在步骤320中，UE 120被配置为向基站提供能够指示多个天线面板与一个或多个DL RS的关联的波束报告。具体地，波束报告包括UE 120的多个天线面板中至少一个天线面板的面板状态、经由所述至少一个天线面板接收的DL RS的索引以及针对DL RS的信道质量测量结果。
在一些实施例中，波束报告包括UE 120的全部天线面板中的每个天线面板所对应的面板状态、接收的DL RS的索引以及针对DL RS的信道质量测量结果。若天线 面板的面板状态为“未激活”，则接收的DL RS的索引以及针对DL RS的信道质量测量结果均为空值。
在另一些实施例中，波束报告可以仅针对能够接收DL RS的那些天线面板，即面板状态不为“未激活”的天线面板，由此可以减小波束报告所需要的传输资源开销。
对于CSI-RS，其索引可以是信道状态信息资源指示(Channel State Information Resource Indicator，CRI)。对于SSB，其索引可以是同步信号块资源指示(Sychronization Signal Block Resource Indicator，SSBRI)。对于CSI-RS资源集和SSB资源集，其索引可以分别是对应的资源集标识(ID)。
在一些实施例中，针对DL RS的信道质量测量结果是层1参考信号接收功率(Layer 1 Reference Signal Received Power，L1-RSRP)或层1信号与干扰加噪声比(L1-SINR)。相比需要高层信令上报，利用L1-RSRP或L1-SINR可以快速向基站反馈信道质量。
在一些实施例中，波束报告还可以可选地包括用于标识天线面板的面板ID或标签。面板ID与标签的区别在于面板ID可以反映相应天线面板的具体实现方式，例如天线阵列的尺寸，而标签则可以隐去这一信息。需要指出，尽管面板ID或标签可以便于基站直接获知具体的天线面板，但在波束报告中并非是必须的。通过在波束报告中包括天线面板的面板状态和对应DL RS的索引，基站已经能够获知天线面板和DL RS之间的关联的存在，即可在后续的下行或上行传输中利用这种关联进行波束指示。
如前所述，在一些实施例中，UE 120被配置为利用不同的天线面板接收每个DL RS，此时，波束报告针对用来接收DL RS的每个天线面板包括其面板状态、由该天线面板接收的DL RS的索引以及针对该DL RS的信道质量测量结果。
图4A示出了根据本公开的实施例的天线面板与DL RS之间的映射关系的一种示例，其中一个天线面板仅用来接收一个DL RS。如图4A所示，UE 120具有四个天线面板410-1至410-4，其中仅有天线面板410-1和410-2被完全激活或部分激活用于下行链路测量。基站110被配置为具有四个DL RS端口，分别对应四个DL RS波束420-1至420-4。由于UE 120事先已确定天线面板仅用于接收一个DL RS波束，因此在实际接收中可能会出现图4A中所示的情形，即波束420-2由天线面板410-1接收，波束420-3由天线面板410-2接收。天线面板410-1和410-2用于接收相应DL RS的接收波束430-1和430-2可以是默认的或者预先选择好的。
天线面板410-1和410-2在接收到DL RS波束420-2和420-3后，对其进行测量， 并向基站提供波束报告。表1示出了对应的波束报告的信令格式示例。波束报告信令的每个条目对应接收DL RS的每个天线面板。在该示例中，条目1对应天线面板410-1，条目2对应天线面板410-2。条目之间的顺序可以任意设定。对于每个条目，即对应每个天线面板，波束报告信令包括该天线面板接收的DL RS的索引、该DL RS的信道质量测量结果和该天线面板的面板状态。DL RS的索引可以由UE基于基站提供的RRC参数CSI-ResourceConfig确定。RRC参数CSI-ResourceConfig用于向UE指示CSI-RS资源是如何配置的。表1中天线面板410-1对应接收的是DL RS#2，其信道质量测量结果是L1 RSRP#2，面板状态为“完全激活”。
可选地，波束信令报告还包括天线面板的面板ID或标签。如表1所示，天线面板410-1的条目中包括的是标签“P1”，该标签不反映天线面板的具体实现方式；天线面板410-2的条目中包括的是面板ID“P2-2*4”，其中“2*4”指示了天线面板410-2包括2*4的天线阵列。虽然表1中示出了不同条目可以分别使用面板ID或标签，但在其它实施例中，各个条目可以统一使用面板ID，或者统一使用标签。

图4B示出了根据本公开的实施例的天线面板与DL RS之间的映射关系的另一种示例，其中一个天线面板用来接收多个DL RS。如图4B所示，与图4A不同，天线面板410-2被事先确定为可以接收两个DL RS波束，例如DL RS波束420-2和420-3。
在一些实施例中，在UE被配置为利用同一天线面板接收多个DL RS时，波束报告包括该同一天线面板的面板状态、该多个DL RS中具有最佳的信道质量测量结果的DL RS的索引以及最佳的信道质量测量结果。表2-1示出了对应的波束报告的信令格式示例。其中与DL RS波束420-2对应的信道质量测量结果L1 RSRP#2优于与DL RS波束420-3对应的信道质量测量结果L1 RSRP#3，因此在与天线面板410-2对应的条目1中，可以仅包括“DL RS#2”和“L1 RSRP#2”。
表2-1：与图4B对应的波束报告示例
Figure PCTCN2022083543-appb-000002
在其它实施例中，在UE被配置为利用同一天线面板接收多个DL RS时，波束报告针对该多个DL RS中的每一个包括该同一天线面板的面板状态、由该多个DL RS共享的组标签、该DL RS的索引以及对应的信道质量测量结果。表2-2示出了对应的波束报告的信令格式示例。与表2-1不同，表2-2中针对由天线面板410-2接收的DL RS波束420-2和420-3分别包括相应的条目，即条目1和条目2。条目1和条目2共享相同的组标签“G1”，由此指示这两个条目对应同一个天线面板。

图4C示出了根据本公开的实施例的天线面板与DL RS之间的映射关系的另一种示例，其中一个DL RS被多个天线面板接收。如图4C所示，天线波束420-2被两个天线面板410-1和410-2同时接收。这种情况下，天线面板410-1和410-2可以被视为一个虚拟面板。UE可以将虚拟面板中的各个天线面板测得的信道质量测量结果进行组合并上报。对信道质量测量结果的组合可以根据情况采用各种方式，例如可以包括取线性平均。表3示出了对应的波束报告的信令格式示例。天线面板410-1和410-2的信道质量测量结果、面板状态以及面板ID/标签(如果有的话)分别在条目1中被组合。尽管表3中示出了被用作一个虚拟面板的两个天线面板410-1和410-2具有不同的面板状态，但在其它实施例中，可以将用作一个虚拟面板的各个天线面板设定为具有相同的面板状态，以方便管理和使用。在一些情况下，UE可以优先选择具有相同面板状态的多个天线面板来用作虚拟面板。

图4D示出了根据本公开的实施例的天线面板与DL RS之间的映射关系的另一种示例，其中多个DL RS为具有相同波束方向的资源集，例如重复参数Repetition被配置为打开ON的CSI-RS资源集或者SSB资源集。如图4D所示，DL RS资源集440中的多个DL RS波束430-1至430-4具有相同的波束方向。UE 120可以利用一个天线面板410-2来产生四个不同的接收波束，分别对应DL RS波束430-1至430-4，由此可以通过测量确定最优的接收波束。由于上下行的信道互易性，这个最优的接收波束也可以用于UE的上行链路发送。表4示出了对应的波束报告的信令格式示例。条目1对应于用于接收DL RS资源集440的天线面板410-2。DL RS索引为DL RS资源集440的索引(例如，CSI-RS资源集ID或者SSB资源集ID)。UE 120可以在波束报告中包括对各个DL RS波束的测量结果，也可以包括由各个接收波束测量的针对该DL RS资源集440的最优的信道质量测量结果。

图5示出了根据本公开的实施例的方法500的示例流程图。方法500可以被用于实现根据本公开的实施例的利用下行参考信号与天线面板之间的关联进行天线面板 选择的方案。与方法300相同，方法500可以在UE 120侧执行。方法500可以包括步骤510至步骤540，其中步骤510与步骤520同图3中的步骤310和步骤320相同，在此不做赘述。
在步骤530中，UE 120被配置为从基站接收DCI。该DCI指示在基站先前发送给UE用于进行信道探测或波束管理的一个或多个DL RS(参见步骤S310)中的由基站选择的DL RS。DL RS的选择可以由基站基于波束报告(参见步骤S320)中的信道质量测量结果和面板状态进行。例如，基站可以在波束报告中选择具有最佳的信道质量测量结果所对应的DL RS。然而，若最佳的信道质量测量结果所对应的面板状态为“仅针对下行链路测量而部分激活”，即相应天线面板并不支持下行链路或上行链路的数据传输，则基站可以进一步选择具有次优的信道质量测量结果所对应的DL RS并同样检查相应的面板状态，以此类推，直至找到与能够支持下行链路和/或上行链路传输的天线面板对应的DL RS。可以认识到，在波束报告中包括面板状态有利于基站选择更加合适的DL RS，进而选择更加合适的面板。在选择好DL RS后，基站将该DL RS的信息包含在DCI中以供发送给UE。
在步骤540中，UE 120被配置为利用在波束报告中指示的用于接收所选择的DL RS的相同的天线面板与基站通信。具体地，UE 120在从接收的DCI中获取到基站所选择的DL RS的信息后，就可以知道基站将在后续的传输中使用与所选择的DL RS相同的发送波束，相应地，UE 120也会使用先前用于接收所选择的DL RS的相同的天线面板来接收该发送波束。根据上下行链路互易性，基站在后续的传输中也可以使用与所选择的DL RS相同的接收波束，相应地，UE 120也会使用先前用于接收所选择的DL RS的相同的天线面板来发送。可以认识到，由于在波束报告中指示了DL RS与天线面板之间的关联，基站通过指示DL RS就间接地进行了面板选择。
2.3更新关联上报
在一些情况下，如前所述，由于UE的旋转、移动、通信阻塞、MPE或功率控制等因素，UE的天线面板的状态可能因此发生变化，或者天线面板测得的信道质量测量结果变得很差，此时已经上报给基站的天线面板与DL RS之间的关联关系将不再适用。UE可以使用新的天线面板接收由先前DL RS指示的发送波束或者接收新的DL RS指示的发送波束。本公开的发明人认识到，由于相比基站，UE能够更加及时地检测天线面板状态、旋转、移动、通信阻塞、MPE状况或功率控制等信息，因此较为有 利的是，由UE主动发起DL RS与天线面板之间的关联更新的上报。
图6示出了根据本公开的实施例的方法600的示例流程图。方法600可以被用于实现根据本公开的实施例的对下行参考信号与天线面板之间的关联的更新进行上报的方案。与方法600相同，方法600可以在UE 120侧执行。方法600可以包括步骤610至步骤640，其中步骤610与步骤620同图3中的步骤310和步骤320相同，在此不做赘述。
在步骤630中，UE 120被配置为响应于检测到第一条件，更新天线面板与DL RS之间的关联。
第一条件可以指示天线面板与DL RS的关联应当发生改变。在一些实施例中，第一条件包括天线面板的面板状态的改变。例如，原来用于接收下行链路波束的天线面板可能由于功率控制而需要关闭。在一些实施例中，第一条件包括针对DL RS的信道质量测量结果小于预定阈值。
更新天线面板和DL RS之间的关联可以包括：(1)使用新的天线面板接收波束报告(例如步骤320中提供的)中原有的DL RS；(2)使用新的天线面板接收新的DL RS；或者(3)使用波束报告(例如步骤320中提供的)中原有的天线面板接收新的DL RS。注意，这里“新的天线面板”和“新的DL RS”都是相对于波束报告中已经关联的天线面板和DL RS而言的。只要“新的天线面板”或者“新的DL RS”替代波束报告中原有的天线面板或者DL RS而形成了新的关联关系，就可以认为更新了天线面板和DL RS之间的关联。
在步骤640中，UE 120被配置为向基站发送更新的波束报告以指示天线面板与DL RS的更新后的关联。
更新的波束报告可以与原来的波束报告(例如步骤320中提供的)具有相同的信令格式。具体而言，更新的波束报告可以包括天线面板的状态、由该天线面板接收的DL RS的索引以及针对该DL RS的信道质量测量结果。更新的波束报告还同样可以可选地包括面板ID或标签。例如，更新的波束报告可以具有以上表1、表2-1、表2-2、表3和表4中示出的类似的信令格式。其中，若更新天线面板和DL RS之间的关联包括使用新的天线面板接收原有的DL RS，那么更新的波束报告中天线面板的状态可以为新的天线面板的面板状态、原有的DL RS的索引以及利用新的天线面板测得的原有DL RS的信道质量测量结果。若更新天线面板和DL RS之间的关联包括使用新的天线面板接收新的DL RS，那么更新的波束报告可以包括新的天线面板的面板状态、新 的DL RS的索引和新的DL RS的信道质量测量结果。若更新天线面板和DL RS之间的关联包括使用原有的天线面板接收新的DL RS，那么更新的波束报告可以包括原有的天线面板面板状态、新的DL RS的索引和新的DL RS的信道质量测量结果。
图7示出了根据本公开的实施例的天线面板和DL RS的关联发生更新的示意图。图7是在图4基础上的延伸，图7中附图标记与图4的附图标记具有相同含义。如图7左侧所示，天线面板410-2已经与DL RS波束420-3建立了关联。由于UE 120发生翻转，天线面板410-2不再是接收基站发送波束的最优选择，而天线面板410-1使用接收波束来接收DL RS波束420-4，即天线面板410-1与DL RS波束420-4发生了新的关联。在这种情况下，UE 120可以主动向基站发送更新的波束报告，该更新的波束报告可以包括新的DL RS波束的索引(例如，“DL RS#4”)、新的DL RS波束的信道质量测量结果(例如，“(由新的天线面板410-1测得的)L1-RSRP#4”)以及新的天线面板410-1的面板状态。
图8和图9分别示出了根据本公开的实施例的用于发送更新的波束报告的示例性信令流程图。其中图8是基于上行链路控制信息UCI的，而图9是基于MAC CE的。
在图8中，在框810处，UE被配置为执行图6中步骤630的步骤，即响应于检测到第一条件，更新天线面板与DL RS之间的关联。随后，在820处，UE向基站发送对于物理上行链路控制信道(Physical Uplink Control Channel，PUCCH)或者物理上行链路共享信道(Physical Uplink Shared Channel，PUSCH)的上行链路调度请求(Scheduling Request，SR)。在830处，UE从基站接收针对PUCCH或者PUSCH的上行链路授权。在840处，UE在上行链路授权配置的PUCCH或PUSCH上发送UCI，该UCI携带了如上文所述的更新的波束报告。UE在发送UCI后就认为，从时间T1开始，更新的波束报告中所指示的更新的天线面板-DL RS关联开始被应用。在850处，基站处理更新的波束报告，以得知更新的关联。由此，在基站看来，从时间T2开始，更新的波束报告中所指示的更新的天线面板-DL RS关联开始被应用。图8所示的基于UCI的关联更新方法具有较低的时延，适用于例如UE高速移动而导致天线面板的面板状态快速发生变化的场景。
在图9中，在框910处，与图8的框810类似，UE被配置为执行图6中步骤630的步骤，即响应于检测到第一条件，更新天线面板与DL RS之间的关联。随后，在920处，UE向基站发送对于PUSCH的上行链路SR。在930处，UE从基站接收针对PUSCH的上行链路授权。在940处，UE在上行链路授权配置的PUSCH上发送MAC  CE，该MAC CE携带了如上文所述的更新的波束报告。在950处，基站处理更新的波束报告，以得知更新的关联。在960处，基站发送针对MAC CE的隐式HARQ，该隐式HARQ具有相同的HARQ过程ID和翻转的新数据指示(toggled New Data Indicator,toggled-NDI)。在该隐式HARQ后，基站和UE都认为，从此时(时间T3)开始，更新的波束报告中所指示的更新的天线面板-DL RS关联开始被应用。图9的基于MAC CE的关联更新方法具有更高的可靠性，而且与现有通信标准或规范能够更好地兼容。
在一些实施例中，在使用图9所示的基于MAC CE的关联更新方法时，更新的波束报告可以具有与原波束报告不同的信令格式。具体来说，更新的波束报告可以包括天线面板的面板状态和对应的更新的上行链路传输配置指示(Transmission Configuration Indicator，TCI)或者联合TCI。
图10示出了根据本公开的实施例的方法1000的示例流程图。方法1000可以被用于实现根据本公开的实施例的用于下行参考信号与天线面板的关联方案。方法1000可以在基站110侧执行。方法1000可以包括步骤1010至步骤1020。
在步骤1010中，基站110被配置为向包括多个天线面板的UE发送一个或多个DL RS。
在一些实施例中，基站110所发送的每个DL RS可以是CSI-RS或SSB。在一些实施例中，基站110所发送的DL RS可以是CSI-RS资源集，其中该CSI-RS资源集的重复参数Repetition被配置为ON。在一些实施例中，UE 120所接收的DL RS可以是SSB资源集。基站可以周期性、半持续或非周期方式发送DL RS。
在步骤1020中，基站110被配置为从UE接收能够指示多个天线面板与一个或多个DL RS的关联的波束报告。具体地，波束报告包括UE的多个天线面板中至少一个天线面板的面板状态、经由所述至少一个天线面板接收的DL RS的索引以及针对DL RS的信道质量测量结果。
在一些实施例中，波束报告包括UE的全部天线面板中的每个天线面板所对应的面板状态、接收的DL RS的索引以及针对DL RS的信道质量测量结果。在另一些实施例中，波束报告可以仅针对能够接收DL RS的那些天线面板，即面板状态不为“未激活”的天线面板。
在一些实施例中，面板状态可以为以下几种状态中的任意一种：(1)“未激活”； (2)“仅针对下行链路测量而部分激活”；(3)“仅针对下行链路测量和数据传输而部分激活”和(4)“完全激活”。在一些实施例中，DL RS的索引可以包括CRI、SSBRI、CSI-RS资源集ID或SSB资源集ID。在一些实施例中，针对DL RS的信道质量测量结果是L1-RSRP或L1-SINR。
在一些实施例中，波束报告信令包括一个或多个条目，每个条目对应UE的一个天线面板。每个条目包括对应天线面板接收的DL RS的索引、该DL RS的信道质量测量结果和该天线面板的面板状态。对于这样的波束报告信令，基站能够获知一个DL RS与一个或多个天线面板相关联，或者多个DL RS与同一个天线面板相关联而且所报告的DL RS对应最佳的信道质量测量结果。
在一些实施例中，波束报告信令包括多个条目，每个条目包括DL RS的索引、DL RS的信道质量测量结果、相同的面板状态和多个条目共享的组标签。对于这样的波束报告信令，基站能够获知多个DL RS与同一个天线面板相关联。
在一些实施例中，波束报告信令包括至少一个条目，该条目包括DL RS资源集ID、信道质量测量结果和面板状态。对于这样的波束报告信令，基站能够获知一个DL RS资源集与一个天线面板相关联。
在一些实施例中，波束报告信令还包括天线面板的面板ID或标签，其中面板ID能够反映天线面板的实现方式，而标签不反映天线面板的具体实现方式。
可选地，基站110可以被配置为在步骤1020之后继续执行步骤1030和步骤1040以实现根据本公开的实施例的利用下行参考信号与天线面板之间的关联进行天线面板选择的方案。
在步骤1030中，基站110被配置为向UE发送DCI。该DCI指示在基站先前发送给UE用于进行信道探测或波束管理的一个或多个DL RS中的经选择的DL RS。如上文结合图5已经介绍的，DL RS的选择可以由基站基于波束报告中的信道质量测量结果和面板状态进行。在一些实施例中，基站110可以通过RRC配置和TCI的下行MAC信令来通知UE由基站所选择的DL RS。更进一步地，基站110通过MAC信令从CORESET(Control Resource Set，控制资源集)对应的备选状态子集中选择特定的TCI状态为有效。由此，UE在接收到该MAC信令后，当在侦听物理下行链路控制信道(Physical Downlink Control Channel，PDCCH)或者物理下行链路共享信道(Physical Downlink Shared Channel，PDSCH)时，认为该PDCCH或PUSCH会使用MAC信令所指定的TCI相关联的DL RS所使用的发送波束。
在一些实施例中，若基站110选择的DL RS是具有相同波束方向的DL RS资源集，例如重复参数Repetition被配置为ON的CSI-RS资源集或SSB资源集，那么在DCI中可以包括该DL RS资源集的信息，也可以包括该参考信号资源集中任何DL RS的信息。
在步骤1040中，基站110被配置为利用与经选择的DL RS的相同的波束与所述UE通信。相同的波束可以包括相同的发送波束，而且根据上下行互易性，相同的波束也可以包括相同的接收波束。
需要注意，图10所示的步骤与图3和图5所示的由UE侧执行的方法相对应，若在此省略的技术细节可以参见图3和图5中的相应描述。
3.上行参考信号与天线面板的关联
图11示出了根据本公开的实施例的方法1100的示例流程图。方法1100可以被用于实现根据本公开的实施例的用于上行参考信号与天线面板的关联方案。方法1100可以在UE 120侧执行。方法1100可以包括步骤1110至步骤1130。
在步骤1110中，UE 120被配置为从基站接收探测参考信号SRS配置，该SRS配置为UE配置多个SRS资源集。SRS配置可以设置SRS资源集的数量，每个SRS资源集中的SRS的数量。SRS配置可以将SRS配置为以周期性、半持续性或非周期性方式发送。与CSI-RS类似，半持续性SRS需要MAC CE的激活/去激活，而非周期性SRS需要DCI命令触发。
在步骤1120中，UE 120被配置为向基站提供SRS-天线面板关联信息。SRS-天线面板关联信息可以包括UE的多个天线面板中的每个天线面板的面板状态和要使用该天线面板发送的SRS资源集的索引或者SRS资源集中任何SRS的索引。
一方面，SRS-天线面板关联信息与上文已介绍的下行参考信号与天线面板的关联方案中用到的波束报告的相同之处在于：都包括面板状态和参考信号(DL RS或SRS)的索引。
与波束报告类似，在一些实施例中，SRS-天线面板关联信息中的面板状态可以为以下几种状态中的任意一种：(1)“未激活”；(2)“仅针对上行链路测量而部分激活”；(3)“仅针对上行链路测量和数据传输而部分激活”和(4)“完全激活”。
与波束报告类似，在一些实施例中，SRS-天线面板关联信息还可以针对每个天线面板包括天线面板的面板ID或标签。
另一方面，SRS-天线面板关联信息与波束报告的不同之处在于：首先，在上行参考信号与天线面板的关联方案中，将天线面板与SRS资源集相关联，相应地，在SRS-天线面板关联信息中可以包括SRS资源集的索引(例如，资源集ID)或者是资源集中任何SRS的索引；其次，在上行参考信号与天线面板的关联方案中可以不包括信道质量测量信息，因为对于SRS，信道测量是在基站处完成的。
在一些实施例中，UE与基站建立初始连接时向基站报告UE能力(Capability)信息。该UE能力信息指示了UE所具有的天线面板的数量。在进一步的实施例中，UE能力信息还指示UE的每个天线面板所支持的最大波束数量。基站在获知这些能力信息后，可以据此配置SRS资源集。例如，基站可以将SRS资源集的数量配置为等于天线面板的数量。在这种情况下，UE可以将每个SRS资源集分配到一个不同的天线面板上，使得SRS资源集与天线面板一一对应。在一些情况下，基站还可以将SRS资源集中的SRS数量配置为不超过天线面板所支持的最大波束数量。
图12示出了根据本公开的实施例的将SRS资源集与天线面板进行关联的示意图。如图12所示，天线面板410-1用于发送SRS资源集#1 1210-1，天线面板410-2用于发送SRS资源集#2 1210-2，天线面板410-3用于发送SRS资源集#2 1210-3。对于这样的关联，仅作为非限制性的示例，UE可以这样设置要报告给基站的SRS-天线面板关联信息：条目1，包括天线面板410-1的面板状态以及SRS资源集1210-1的索引(例如“SRS资源集#1”)；条目2，包括天线面板410-2的面板状态以及SRS资源集1210-2的索引(例如“SRS资源集#2”)；以及条目3，包括天线面板410-3的面板状态以及SRS资源集1210-3的索引(例如“SRS资源集#3”)。
返回到图11，在步骤1130中，UE 120被配置为基于SRS-天线面板关联信息使用天线面板向基站发送相关联的SRS资源集中的SRS。UE 120可以依次使用每个天线面板向基站发送与该天线面板相关联的SRS资源集中的每一个SRS，以供基站进行信道探测。如接下来将介绍的，基于SRS的信道探测结果将被基站与SRS-天线面板关联信息相结合地用于天线面板选择。
与结合图5介绍的利用波束报告进行天线面板选择的方案类似，SRS-天线面板关联信息也可以用于天线面板选择。类似步骤530，UE 120可以被配置为从基站接收DCI，其中DCI指示在先前发送给基站用于进行信道探测的SRS中由基站选择的SRS资源集或SRS资源集中的经选择的SRS。与步骤530中对DL RS的选择类似，SRS的选择可以由基站基于对接收到的SRS的测量和SRS-天线面板关联信息中的面板状 态进行。例如，基站可以SRS中选择具有最佳的测量结果所对应的SRS。然而，若具有最佳的测量结果的SRS所关联的天线面板的面板状态为“仅针对上行链路测量而部分激活”，即相应天线面板并不支持下行链路或上行链路的数据传输，则基站可以进一步选择具有次优的测量结果所对应的SRS并同样检查相应的面板状态，以此类推，直至找到与能够支持下行链路和/或上行链路传输的天线面板对应的SRS。可以认识到，在SRS-天线面板关联信息中包括面板状态有利于基站选择更加合适的SRS，进而选择更加合适的天线面板。在选择好SRS后，基站将该SRS或SRS所在的资源集的信息包含在DCI中以供发送给UE。
类似步骤540，在接收到DCI后，UE 120被配置为利用在SRS-天线面板关联信息中指示的用于发送经选择的SRS资源集或经选择的SRS的相同的天线面板与基站通信。具体地，UE 120在从接收的DCI中获取到基站所选择的SRS的信息后，就可以知道基站将在后续的传输中使用与所选择的SRS相对应的接收波束，相应地，UE120也会使用先前用于发送所选择的SRS的相同的天线面板来发送上行链路传输。而且，由于上下行链路的互易性，UE 120也可以使用该相同的天线面板来接收来自基站的下行链路传输。可以认识到，由于在SRS-天线面板关联信息中指示了SRS与天线面板之间的关联，基站通过指示SRS就间接地进行了面板选择。
SRS-天线面板关联信息的更新的上报与上文结合图6-9介绍的波束报告的更新的上报类似。如前所述，由于UE的旋转、移动、通信阻塞、MPE或功率控制等因素，UE的天线面板的状态可能因此发生变化，此时已经上报给基站的天线面板与SRS之间的关联关系将不再适用。UE可以使用新的天线面板与SRS相关联，并可以主动发起SRS与天线面板之间的关联更新的上报。
在一些实施例中，UE 120可以配置为响应于检测到第一条件而更新SRS资源集与天线面板之间的关联，然后向基站发送更新的SRS-天线面板关联信息。具体地，第一条件指示天线面板与SRS资源集的关联应当发生改变。在一些实施例中，第一条件可以包括与SRS资源集发生关联的天线面板的面板状态发生改变。例如，天线面板可能被改变为仅支持上行链路测量而不支持上行或下行链路数据传输。
在一些实施例中，更新SRS资源集与天线面板之间的关联可以包括计划使用新的天线面板发送原有的SRS资源集中的SRS。
在一些实施例中，更新的SRS-天线面板关联信息可以与原有的SRS-天线面板关联信息具有相同的信令格式。具体而言，更新的SRS-天线面板关联信息可以包括新的 天线面板的面板状态和要使用该新的天线面板发送的原有的SRS资源集的索引或者原有的SRS资源集中任何SRS的索引。
在另一些实施例中，更新的SRS-天线面板关联信息可以与原有的SRS-天线面板关联信息具有不同的信令格式。具体而言，更新的SRS-天线面板关联信息可以包括新的天线面板的面板状态和对应的更新的上行链路TCI或者联合TCI。
发送更新的SRS-天线面板关联信息的方法同样可以包括基于UCI和基于MAC CE两种。与图8类似，在基于UCI的方法中，UE被配置为向基站发送上行链路SR，并在得到调度授权后，利用经调度的PUSCH或PUCCH信道在UCI中发送更新的SRS-天线面板关联信息。与图9类似，在基于MAC CE的方法中，UE被配置为向基站发送上行链路SR，并在得到调度授权后，利用经调度的PUSCH在MAC CE中发送更新的SRS-天线面板关联信息并最终以从基站接收到隐式HARQ而结束，其中隐式HARQ具有相同的HARQ过程ID以及翻转的新数据指示NDI。关于两种方法的进一步细节可以参照图8和图9的相应描述，在此不做赘述。
图13示出了示出了根据本公开的实施例的方法1300的示例流程图。方法1300可以被用于实现根据本公开的实施例的用于上行参考信号与天线面板的关联方案。方法1300可以在基站110侧执行。方法1300可以包括步骤1310至步骤1330。可以看到，用于基站110侧的方法1300与用于UE侧的方法1100相对应，因此，在此粗略提及的特征或功能的具体细节可以具体参照对方法1100的介绍。
在步骤1310中，基站110被配置为向UE发送探测参考信号SRS配置，该SRS配置为UE配置多个SRS资源集。SRS配置可以设置SRS资源集的数量。进一步地，SRS配置还可以设置每个SRS资源集中的SRS的数量。
在步骤1320中，基站110被配置为从UE接收SRS-天线面板关联信息。SRS-天线面板关联信息可以包括UE的多个天线面板中的每个天线面板的面板状态和要使用该天线面板发送的SRS资源集的索引或者SRS资源集中任何SRS的索引。
在步骤1330中，基站110被配置为从UE接收SRS资源集中的SRS，以进行上行信道探测。
类似地，在基站侧执行的利用SRS-天线面板关联信息进行天线面板选择以及对SRS-天线面板关联信息进行更新的内容同样可以参照对UE侧描述的相应方案，在此不做赘述。
以上描述了根据本公开的用于在无线通信系统中的将UE的天线面板与参考信号 进行关联以及对关联进行更新的电子设备和方法的实施例。在本公开的实施例中，通过由UE主动向基站报告天线面板的面板状态，可以辅助基站做出更合适的面板选择，减小因选择不合适而导致的延时或通信质量下降，保证用户体验。另外，通过由UE向基站报告天线面板与参考信号之间的关联，可以方便基站通过指示参考信号就能够间接指示UE所应该使用的天线面板，由此使得天线面板的选择更快速。此外，通过UE主动进行对天线面板与参考信号之间的关联进行更新，可以使得基站能够更及时地对UE的状态变化做出响应，从而尽量保证通信的质量。
应指出，上述描述仅仅是示例性的。本公开的实施例还可以任何其它适当的方式执行，仍可实现本公开的实施例所获得的有利效果。而且，本公开的实施例同样可应用于其它类似的应用实例，仍可实现本公开的实施例所获得的有利效果。
