背景技术
在5G NR(New Radio，新空口)系统中，接入网设备和终端可以使用波束(beam)收发信息。例如，接入网设备和终端之间交互的控制信令和业务数据，都可以使用波束进行收发。
在相关技术中，终端采用下述方式确定DCI(Downlink Control Information，下行控制信息)的接收波束：终端按照接入网设备提供的测量配置，对波束进行测量之后，向接入网设备发送波束测量报告，该波束测量报告中包括波束对应的RS(Reference Signal，参考信号)类型、RS标识和L1-RSRP(Layer 1-Reference Signal Received Power，层一的参考信号接收功率)；接入网设备根据终端发送的波束测量报告，确定至少一个Type D的TCI(Transmission Configuration Indication，传输配置指示)状态，每个TCI状态对应于一个RS标识；接入网设备通过RRC(Radio Resource Control，无线资源控制)信令将上述至少一个TCI状态通知给终端，包括TCI状态的标识及其对应的RS类型和RS标识；若RRC信令告知了多个TCI状态，则接入网设备再使用MAC(Medium Access Control，介质访问控制)CE(Control Element，控制单元)信令激活上述多个TCI状态中的一个TCI状态，该被激活的TCI状态即为接入网设备给该终端的PDCCH(Physical Downlink Control Channel，物理下行控制信道)的传输状态配置，即告知终端接收PDCCH上的DCI时使用的接收波束应当与接收该TCI状态对应的RS所使用的接收波束相同。之后，终端便可以使用上述确定的接收波束，接收PDCCH上的DCI。
另外，终端可以采用类似的方式确定下行数据的接收波束：接入网设备根据终端的波束测量报告确定多个TCI状态之后，通过RRC信令将上述多个TCI状态通知给终端；之后，接入网设备再使用MAC CE信令激活上述多个TCI 状态中的若干个(比如最多8个)TCI状态，然后再通过DCI告知终端用于PDSCH(Physical Downlink Shared Channel，物理下行共享信道)的是上述被激活的若干个TCI状态中的哪一个TCI状态。该通过DCI告知的TCI状态即为接入网设备给该终端的PDSCH的传输状态配置，即告知终端接收PDSCH上的下行数据时使用的接收波束应当与接收该TCI状态对应的RS所使用的接收波束相同。之后，终端便可以使用上述确定的接收波束，接收PDSCH上的下行数据。
当终端发生移动或接入网设备的天线方向发生改变时，接入网设备配置给终端的用于发送下行控制信息和下行数据的波束可能会发生变化。如果不更新TCI状态，则会使得给终端配置的发送和接收波束都不是最合适的。为了更新TCI状态，就需要终端向接入网设备发送波束测量报告。但是，目前波束测量报告的上报方式是周期性的、半静态的或者非周期性的，且该上报方式是由接入网设备配置的。其中，半静态的上报方式是指终端接收到接入网设备发送的激活信令之后，才开始向接入网设备发送波束测量报告，当发送满一定次数或者接收到接入网设备发来的去激活信令时终端停止上报。对于周期性和半静态的上报方式，如果上报时间间隔太小会引发较多不必要的上报，不利于节省终端的信令开销和功耗；如果上报时间间隔太大又会引发上报不及时的问题，导致波束失败(beam failure)等情况发生。而非周期性的上报方式，也同样存在上报不及时的问题。
因此，相关技术提供的波束测量报告的上报方法，上报时机不够合理准确。

具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
本公开实施例描述的网络架构以及业务场景是为了更加清楚地说明本公开实施例的技术方案，并不构成对本公开实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本公开实施例提供的技术方案对于类似的技术问题，同样适用。
图1是根据一示例性实施例示出的一种网络架构的示意图。该网络架构可以包括：接入网设备110和终端120。
接入网设备110部署在接入网中。5G NR系统中的接入网可以称为NG-RAN(New Generation-Radio Access Network，新一代无线接入网)。接入 网设备110与终端120之间通过某种空口技术互相通信，例如可以通过蜂窝技术相互通信。
接入网设备110可以是基站(Base Station，BS)，基站是一种部署在接入网中用以为终端提供无线通信功能的装置。基站可以包括各种形式的宏基站，微基站，中继站，接入点等等。在采用不同的无线接入技术的系统中，具备基站功能的设备的名称可能会有所不同，例如在5G NR系统中，称为gNodeB或者gNB。随着通信技术的演进，“基站”这一名称可能会变化。为方便描述，本公开实施例中，上述为终端提供无线通信功能的装置统称为接入网设备。

本公开实施例中的“5G NR系统”也可以称为5G系统或者NR系统，但本领域技术人员可以理解其含义。本公开实施例描述的技术方案可以适用于5G NR系统，也可以适用于5G NR系统后续的演进系统。
在本公开提供的技术方案中，通过终端获取波束测量结果，当终端检测到波束测量结果满足预设条件时，才向接入网设备发送波束测量报告，相比于终端采用周期性、非周期性或者半静态的方式向接入网设备发送波束测量报告，本公开实施例提供的技术方案，克服了上报不及时和存在较多不必要的上报的问题，终端发送波束测量报告的时机合理准确。另外，通过终端在检测到波束测量结果满足预设条件时向接入网设备发送波束测量报告，使得接入网设备能够根据波束测量报告及时地对TCI状态集合进行更新，确保终端选用合适的波束进行下行接收。下面，将通过几个实施例，对本公开提供的技术方案进行介绍说明。
图2是根据一示例性实施例示出的一种波束测量报告的上报方法的流程图。该方法可应用于图1所示的网络架构中。该方法可以包括如下几个步骤。
在步骤201中，终端获取波束测量结果。
在本公开实施例中，波束测量结果包括：目标RS集合中包括的n个RS 对应的信道测量参数，以及除目标RS集合之外的m个其它RS对应的信道测量参数，其中，目标RS集合对应于目标TCI状态集合，目标TCI状态集合中包括接入网设备向终端指示的n个TCI状态，n为正整数，m为正整数。
每个TCI状态分别对应于每一个RS，不同的TCI状态对应于不同的RS。
在一个示例中，目标TCI状态集合是接入网设备通过RRC信令向终端指示的PDCCH的TCI状态集合，或接入网设备通过MAC CE信令激活的PDCCH的TCI状态集合。对于波束传输场景，终端在确定DCI的接收波束时，接入网设备可以通过RRC信令向终端指示PDCCH的TCI状态集合，该TCI状态集合中包括至少一个TCI状态。可选地，该TCI状态集合最多包括64个TCI状态。另外，若接入网设备通过RRC信令向终端指示的PDCCH的TCI状态集合中包括多个TCI状态，则接入网设备还可以通过MAC CE信令激活上述多个TCI状态中的一个TCI状态。
在另一个示例中，目标TCI状态集合是接入网设备通过RRC信令向终端指示的PDSCH的TCI状态集合，或通过MAC CE信令激活的PDSCH的TCI状态集合。对于波束传输场景，终端在确定下行数据的接收波束时，接入网设备可以通过RRC信令向终端指示PDSCH的TCI状态集合，该TCI状态集合中包括至少一个TCI状态。可选地，该TCI状态集合最多包括64个TCI状态。另外，接入网设备还可以通过MAC CE信令激活上述多个TCI状态中的至少一个TCI状态，如激活上述多个TCI状态中的最多8个TCI状态。
在本公开实施例中，其它RS是作为候选RS，用于更新目标TCI状态集合的RS。可选地，其它RS可以由接入网设备配置并告知给终端。
在本公开实施例中，信道测量参数可以包括以下至少一种：信道质量、L1-RSRP、L1-RSRQ(Layer 1-Reference Signal Received Quality，层一的参考信号的接收质量)、L1-SINR(Layer 1-Signal to Interference and Noise Ratio，层一的信号与干扰加噪声比)。当信道测量参数的类型为信道质量或L1-RSRQ或L1-SINR时，终端需要测量每个RS对应的RSRP以及干扰，需要说明的是，针对同一个RS对应的RSRP和干扰需要使用相同的接收波束来测量。
需要说明的是，终端需要获取哪些RS对应的信道测量参数，可以由接入网设备配置并告知给终端。另外，终端需要获取哪种类型的信道测量参数，也可以由接入网设备配置并告知给终端。
此外，终端可以周期性地或者非周期性地获取波束测量结果。
在步骤202中，当波束测量结果满足预设条件时，终端向接入网设备发送波束测量报告。
预设条件是指预先设置好的触发终端向接入网设备发送波束测量报告的条件。预设条件可以由接入网设备配置并告知给终端。
在本公开实施例中，波束测量报告用于触发接入网设备对目标TCI状态集合进行更新。
终端可以通过PUCCH(Physical Uplink Control Channel，物理上行控制信道)或PUSCH(Physical Uplink Shared Channel，物理上行共享信道)向接入网设备发送波束测量报告。
波束测量报告可以包括：k个RS的标识信息，以及k个RS对应的信道测量参数的指示信息，k为大于1的整数；其中，k个RS包括：n个RS以及m个其它RS中信道测量参数大于目标RS对应的信道测量参数的至少一个其它RS，目标RS是指n个RS中信道测量参数最小的RS。
RS的标识信息也称为RS index，用于唯一指示该RS。不同的RS对应于不同的标识信息。在本公开实施例中，RS可以是NZP CSI-RS(Non-Zero Power Channel State Information Reference Signal，非零功率信道状态信息参考信号)，也可以是SSB(Synchronization Signal Block，同步信号块)。
可选地，预设条件包括以下任意一项：
1、波束测量结果所包括的各个RS对应的信道测量参数中，按由大到小的顺序排在前w个的RS与上一次获取的波束测量结果相比不同，w为正整数；
终端在上述步骤201中获取的波束测量结果可以称为本次获取的波束测量结果。上一次获取的波束测量结果即是在本次之前一次获取的波束测量结果。另外，w的取值可以预先设定，如由接入网设备配置，本公开实施例对此不作限定。
例如，目标RS集合包括以下RS：RS#1、RS#2和RS#3，其它RS包括RS#4和RS#5。上一次获取的波束测量结果中，按信道测量参数由大到小对各个RS进行排序依次为：RS#1、RS#2、RS#3、RS#4和RS#5。本次获取的波束测量结果中，按信道测量参数由大到小对各个RS进行排序依次为：RS#4、RS#1、RS#2、RS#3和RS#5。假设w为3，由于前后两次排序结果中，前3个RS发生了改变，因此满足上述预设条件。此时，终端可以向接入网设备发送波束测量报告，该波束测量报告中可以包括目标RS集合中各个RS(也即 RS#1、RS#2和RS#3)对应的信道测量参数的指示信息，还可以包括RS#4对应的信道测量参数的指示信息。
当波束测量结果满足这种预设条件时，说明信道测量参数较大的几个RS的排序发生了改变，此时终端向接入网设备发送波束测量报告，以便接入网设备根据波束测量报告对目标TCI状态集合进行更新，如将信道测量参数较大的RS对应的TCI状态添加至目标TCI状态集合中，并将信道测量参数较小的RS对应的TCI状态从目标TCI状态集合中删除。
2、目标RS集合中存在至少一个RS对应的信道测量参数小于第一门限值；
其中，第一门限值可以预先设定，如由接入网设备配置或者由协议预先规定，本公开实施例对此不作限定。
例如，目标RS集合包括以下RS：RS#1、RS#2和RS#3，信道测量参数的类型为L1-RSRP。假设RS#1对应的L1-RSRP小于第一门限值，RS#2和RS#3对应的L1-RSRP不小于第一门限值。在这种情况下，波束测量结果满足上述预设条件。此时，终端可以向接入网设备发送波束测量报告，该波束测量报告中可以包括目标RS集合中各个RS(也即RS#1、RS#2和RS#3)分别对应的L1-RSRP的指示信息。
当波束测量结果满足这种预设条件时，说明目标TCI状态集合中存在信道测量参数较小的RS对应的TCI状态，此时终端向接入网设备发送波束测量报告，以便接入网设备根据波束测量报告对目标TCI状态集合进行更新，如将信道测量参数较小的RS对应的TCI状态从目标TCI状态集合中删除。
3、目标RS集合中存在至少一个RS对应的信道测量参数与预设偏移值之和，小于m个其它RS对应的信道测量参数的最大值；
其中，预设偏移值可以预先设定，如由接入网设备配置或者由协议预先规定，本公开实施例对此不作限定。可选地，预设偏移值大于0。
例如，目标RS集合包括以下RS：RS#1、RS#2和RS#3，其它RS包括RS#4和RS#5，信道测量参数的类型为L1-RSRP。假设其它RS对应的L1-RSRP的最大值为RS#5对应的L1-RSRP，RS#2对应的L1-RSRP与预设偏移值之和小于RS#5对应的L1-RSRP，因此满足上述预设条件。此时，终端可以向接入网设备发送波束测量报告，该波束测量报告中可以包括目标RS集合中各个RS(也即RS#1、RS#2和RS#3)对应的L1-RSRP的指示信息，还可以包括RS#5对应的L1-RSRP的指示信息。
当波束测量结果满足这种预设条件时，说明目标TCI状态集合中存在信道测量参数较小的RS对应的TCI状态，且存在信道测量参数较大的其它RS对应的TCI状态，此时终端向接入网设备发送波束测量报告，以便接入网设备根据波束测量报告对目标TCI状态集合进行更新，如将信道测量参数较大的其它RS对应的TCI状态添加至目标TCI状态集合中，并将信道测量参数较小的RS对应的TCI状态从目标TCI状态集合中删除。
4、m个其它RS中存在至少一个其它RS对应的信道测量参数大于第二门限值；
其中，第二门限值可以预先设定，如由接入网设备配置或者由协议预先规定，本公开实施例对此不作限定。
例如，其它RS包括RS#4和RS#5，信道测量参数的类型为L1-RSRP。假设RS#4对应的L1-RSRP大于第二门限值，RS#5对应的L1-RSRP不大于第二门限值。在这种情况下，波束测量结果满足上述预设条件。此时，终端可以向接入网设备发送波束测量报告，该波束测量报告中可以包括目标RS集合中各个RS对应的L1-RSRP的指示信息，以及RS#4对应的L1-RSRP的指示信息。
当波束测量结果满足这种预设条件时，说明存在信道测量参数较大的其它RS对应的TCI状态，此时终端向接入网设备发送波束测量报告，以便接入网设备根据波束测量报告对目标TCI状态集合进行更新，如将信道测量参数较大的其它RS对应的TCI状态添加至目标TCI状态集合中。
5、目标RS集合中存在至少一个RS对应的信道测量参数小于第三门限值，且m个其它RS中存在至少一个其它RS对应的信道测量参数大于第四门限值。
其中，第三门限值和第四门限值可以预先设定，如由接入网设备配置或者由协议预先规定，本公开实施例对此不作限定。
例如，目标RS集合包括以下RS：RS#1、RS#2和RS#3，其它RS包括RS#4和RS#5，信道测量参数的类型为L1-RSRP。假设RS#2对应的L1-RSRP小于第三门限值，且RS#5对应的L1-RSRP大于第四门限值，因此满足上述预设条件。此时，终端可以向接入网设备发送波束测量报告，该波束测量报告中可以包括目标RS集合中各个RS(也即RS#1、RS#2、和RS#3)分别对应的L1-RSRP的指示信息，还可以包括RS#5对应的L1-RSRP的指示信息。
当波束测量结果满足这种预设条件时，说明目标TCI状态集合中存在信道测量参数较小的RS对应的TCI状态，且存在信道测量参数较大的其它RS对 应的TCI状态，此时终端向接入网设备发送波束测量报告，以便接入网设备根据波束测量报告对目标TCI状态集合进行更新，如将信道测量参数较大的其它RS对应的TCI状态添加至目标TCI状态集合中，并将信道测量参数较小的RS对应的TCI状态从目标TCI状态集合中删除。
在本公开实施例中，RS对应的信道测量参数的指示信息可用于表示该信道测量参数的大小。在一个示例中，波束测量报告中k个RS对应的信道测量参数的指示信息可以用如下方式表示：k个RS中，最优RS对应的信道测量参数的指示信息采用a个比特表示，最优RS是k个RS中信道测量参数最大的RS，a为正整数；k个RS中，除最优RS之外的每一个剩余RS对应的信道测量参数的指示信息采用b个比特表示，b为正整数。可选地，上述a个比特用于表示最优RS对应的信道测量参数的绝对值。另外，第i个剩余RS对应的信道测量参数的指示信息，用于指示第i个剩余RS对应的信道测量参数与最优RS对应的信道测量参数的差值，i为正整数。上述a、b的取值可以根据信道测量参数的类型及其对应的取值范围进行设定。例如，当信道测量参数为L1-RSRP时，a＝7且b＝4。
可选地，上述b个比特所形成的多种不同序列中，选用指定序列用于指示RS对应的信道测量参数小于预设阈值。例如，当b＝4时，可以形成16种不同序列，假设选用“0000”用于指示RS对应的信道测量参数小于预设阈值。当某一RS对应的信道测量参数小于预设阈值时，说明该RS对应的波束发生波束失败。预设阈值可以根据信道测量参数的类型进行设定，例如当信道测量参数为L1-RSRP时，预设阈值设定为-140db。在这种方式下，当接入网设备从波束测量报告中发现某个RS对应的信道测量参数的指示信息采用指定序列表示时，即可以获知该RS对应的波束发生波束失败。后续，接入网设备可以将该RS对应的TCI状态从目标TCI状态集合中删除。
可选地，波束测量报告还包括参数类型指示信息。如果有多种不同类型的信道测量参数供终端选用，则终端可以在波束测量报告中添加参数类型指示信息，用于指示信道测量参数的类型。
在步骤203中，接入网设备根据波束测量报告对目标TCI状态集合进行更新。
在一个示例中，接入网设备在目标TCI状态集合中增加至少一个TCI状态，和/或，在目标TCI状态集合中删除至少一个TCI状态；其中，增加至目标TCI 状态集合中的TCI状态对应的RS的信道测量参数大于从目标TCI状态集合中删除的TCI状态对应的RS的信道测量参数。
示例性地，假设接入网设备接收到的波束测量报告中，包括目标RS集合中包含的各个RS(如RS#1、RS#2和RS#3)对应的信道测量参数的指示信息，以及至少一个其它RS(如RS#4)对应的信道测量参数的指示信息。如果接入网设备根据上述信息确定，RS#4对应的信道测量参数大于RS#2对应的信道测量参数，则接入网设备可以将RS#2对应的TCI状态从目标TCI状态集合中删除，并将RS#4对应的TCI状态增加至目标TCI状态集合中。
在步骤204中，接入网设备向终端发送TCI状态更新信息。
TCI状态更新信息用于指示更新后的目标TCI状态集合中包括的TCI状态。
在一个示例中，TCI状态更新信息包括更新后的目标TCI状态集合中的每一个TCI状态对应的RS的标识信息。
在另一个示例中，TCI状态更新信息包括增加指示信息和/或删除指示信息，其中，增加指示信息用于指示需要增加至目标TCI状态集合中的TCI状态，删除指示信息用于指示需要从目标TCI状态集合中删除的TCI状态。
可选地，接入网设备通过RRC信令向终端发送TCI状态更新信息。相应地，终端接收接入网设备发送的TCI状态更新信息，并根据TCI状态更新信息对目标TCI状态集合进行更新。
综上所述，本公开实施例提供的技术方案中，通过终端获取波束测量结果，当终端检测到波束测量结果满足预设条件时，才向接入网设备发送波束测量报告，相比于终端采用周期性、非周期性或者半静态的方式向接入网设备发送波束测量报告，本公开实施例提供的技术方案，克服了上报不及时和存在较多不必要的上报的问题，终端发送波束测量报告的时机合理准确。
另外，通过终端在检测到波束测量结果满足预设条件时向接入网设备发送波束测量报告，使得接入网设备能够根据波束测量报告及时地对TCI状态集合进行更新，确保终端选用合适的波束进行下行接收。
在上述方法实施例中，仅从接入网设备和终端交互的角度进行介绍说明，上述有关接入网设备的步骤可以单独实现成为接入网设备一侧的波束测量报告的上报方法，上述有关终端的步骤可以单独实现成为终端一侧的波束测量报 告的上报方法。
