Description

一种波束指示方法、装置、设备及存储介质 技术领域
本公开涉及通信技术领域，尤其涉及一种波束指示方法、装置、设备及存储介质。
背景技术
在新无线网络(new radio，NR)中，特别是通信频段在频率范围(frequency range)2时，由于高频信道衰减较快，为了保证覆盖范围，需要使用基于波束(beam)的发送和接收。
在一些波束管理过程中，网络设备会配置用于波束测量的参考信号资源集合。终端对该参考信号资源集合中的参考信号资源进行测量。终端会将其中部分比较强的参考信号资源标识(identity，ID)以及对应的层1参考信号接收功率(layer 1 reference signal received power，L1-RSRP)和/或层1信号干扰噪声比(layer 1 signal to interference plus noise ratio，L1-SINR)上报给网络设备。
目前传统的方式中，网络设备配置的参考信号资源集合中包括X个参考信号，每个参考信号对应网络设备不同的发送波束。那针对每个参考信号，终端需要使用所有接收波束来针对该参考信号进行测量。所以终端需要测量的波束对的数量为M*N个。其中，M表示网络设备发送波束数量，N为终端接收波束数量。
在一些情况下，为了减少终端测量的波束对的数量，可以采用人工智能(artificial intelligence，AI)模型进行波束预测。若AI模型位于网络设备上，则网络设备输出的优选波束对中的发送波束，可能是终端没测量过的，或者是终端测量过，但不是基于优选波束对中的接收波束测量的。
在这种情况下，若网络设备采用优选波束对中的发送波束发送下行信道上的数据或下行信号时，网络设备即使指示该发送波束对应的参考信号标识，终端也是不知道采用哪个接收波束来进行接收下行信道上的数据或下行信号。因此，如何指示终端优选波束对中的发送波束和/或接收波束，是需要解决的问题。

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。
本公开所涉及的通信方法可以应用于图1所示的无线通信***100中。该网络***可以包括网络设备110和终端120。可以理解的是，图1所示的无线通信***仅是进行示意性说明，无线通信***中还可包括其它网络设备，例如还可以包括核心网络设备、无线中继设备和无线回传设备等，在图1中未画出。本公开实施例对该无线通信***中包括的网络设备数量和终端数量不做限定。
进一步可以理解的是，本公开实施例的无线通信***，是一种提供无线通信功能的网络。无线通信***可以采用不同的通信技术，例如码分多址(Code Division Multiple Access,CDMA)、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)、时分多址(Time Division Multiple Access，TDMA)、频分多址(Frequency Division Multiple Access，FDMA)、正交频分多址(Orthogonal Frequency-Division Multiple Access，OFDMA)、单载波频分多址(Single Carrier FDMA，SC-FDMA)、载波侦听多路访问/冲突避免(Carrier Sense Multiple Access with Collision Avoidance)。根据不同网络的容量、速率、时延等因素可以将网络分为2G(英文：Generation)网络、3G网络、4G网络或者未来演进网络，如第五代无线通信***(The 5th Generation Wireless Communication System，5G)网络，5G网络也可称为是新无线网络(New Radio，NR)。为了方便描述，本公开有时会将无线通信网络简称为网络。
进一步的，本公开中涉及的网络设备110也可以称为无线接入网络设备。该无线接入 网络设备可以是：基站、演进型基站(evolved Node B，eNB)、家庭基站、无线保真(Wireless Fidelity，WIFI)***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(transmission and receiving point，TRP)等，还可以为NR***中的gNB，或者，还可以是构成基站的组件或一部分设备等。当为车联网(V2X)通信***时，网络设备还可以是车载设备。应理解，本公开的实施例中，对网络设备所采用的具体技术和具体设备形态不做限定。
进一步的，本公开中涉及的终端120，也可以称为终端设备、用户设备(User Equipment，UE)、移动台(Mobile Station，MS)、移动终端(Mobile Terminal，MT)等，是一种向用户提供语音和/或数据连通性的设备，例如，终端可以是具有无线连接功能的手持式设备、车载设备等。目前，一些终端的举例为：智能手机(Mobile Phone)、口袋计算机(Pocket Personal Computer，PPC)、掌上电脑、个人数字助理(Personal Digital Assistant，PDA)、笔记本电脑、平板电脑、可穿戴设备、或者车载设备等。此外，当为车联网(V2X)通信***时，终端设备还可以是车载设备。应理解，本公开实施例对终端所采用的具体技术和具体设备形态不做限定。
本公开实施例中，网络设备110与终端120可以采用任意可行的无线通信技术以实现相互传输数据。其中，网络设备110向终端120发送数据或控制信息所对应的传输通道称为下行信道(downlink，DL)，终端120向网络设备110发送数据或控制信息所对应的传输通道称为上行信道(uplink，UL)。可以理解的是，本公开实施例中所涉及的网络设备可以是基站。当然网络设备还可以是其它任意可能的网络设备，终端可以是任意可能的终端，本公开不作限定。
在NR中，特别是通信频段在frequency range 2时，由于高频信道衰减较快，为了保证覆盖范围，需要使用基于beam的发送和接收。
在传统的波束管理过程中，网络设备会配置用于波束测量的参考信号资源集合。终端对该参考信号资源集合中的参考信号资源进行测量。终端会将其中部分比较强的参考信号资源ID以及对应的L1-RSRP和/或L1-SINR上报给网络设备。
目前传统的方式中，网络设备配置的参考信号资源集合中包括X个参考信号，每个参考信号对应网络设备不同的发送波束。那针对至少一个参考信号，终端需要使用所有接收波束来针对该参考信号进行测量，以获得所有接收波束分别对应的波束测量质量。在一些情况下可以确定出一个或多个最好的波束测量质量，和/或最好的波束测量质量所对应的波束标识。所以终端需要测量的波束对的最大数量为M*N个。其中，M表示网络设备发送波束数量，N为终端接收波束数量。
另外，如果配置的是周期性的波束测量上报，终端还需要针对每个周期的参考信号进行测量，并上报测量得到的波束测量质量。
在一些情况下，为了减少终端测量的波束对的数量，可以采用人工智能(artificial intelligence，AI)模型进行波束预测。例如，可以对波束进行预测，确定优选波束。可以理解，优选波束可以是优选发送波束、优选接收波束或者是优选波束对。其中，优选波束对为优选发送波束和优选接收波束构成的波束对。优选波束可以是AI模型预测出的波束质量满足条件的波束。对于下行而言，一个网络设备的发送波束和一个终端的接收波束可以构成一个波束对。那么，对于预测波束的AI模型在网络设备上运行的情况下，网络设备基于AI模型的输出确定的优选波束中，对于优选发送波束或者优选波束对中的优选发送波束，可能是终端没有测量过的，或者可能是终端测量过，但是并非基于优选接收波束进行测量的。在这种情况下。若网络设备基于该优选发送波束进行信道/信号传输，且基于传统的波束指示方法仅向终端指示发送波束对应的参考信号标识时，终端则可能不知道采用哪个接收波束进行接收。
在相关技术中，通常是网络设备发送参考信号，然后终端进行测量上报。例如参考信号(reference signal，RS)#1，终端会利用自身设备配置的多个接收(receive，Rx)波束，并将最好的Rx beam接收时对应的L1-RSRP和/或L1-SINR、以及RS的ID上报给网络设备。而这个RS#1对应的最好的Rx beam终端会进行保存。那么，网络设备接下来如果需要基于RS#1的发送波束来传输信道上的数据/信号，网络设备可以利用传输配置指示(transmission configuration indication，TCI)状态或者空间关系信息(spatialrelationinfo)指示RS ID，则终端会基于存储的RS ID对应的最好Rx beam来接收。
但是，目前由于网络设备基于AI模型预测的优选波束对应的RS，终端并不知道其对应的最好的Rx beam是哪个。那么网络设备如何向终端指示优选波束，是需要解决的问题。
因此，本公开通过网络设备指示终端接收波束的相关信息，使得终端可以采用相应的接收波束接收网络设备发送的数据/信号，提高通信效率。同时可以减少基于波束预测时造成的参考信号开销。
图2是根据一示例性实施例示出的一种波束指示方法流程图，如图2所示，方法应用于终端，可以包括以下步骤：
在步骤S11中，接收网络设备发送的波束指示信息。
在一些实施例中，终端可以接收网络设备发送的波束指示信息。该波束指示信息可以包括准共址(quasico-location，QCL)类型(type)D。其中，QCL type D可以用于指示以下至少一项信息：参考信号标识；目标接收波束的接收波束信息。
在一些实施例中，QCL type D可以用于指示参考信号标识。其中，标识可以ID或者索引(index)。可以理解，参考信号标识可以用于隐式指示终端发送参考信号的发送波束。即参考信号标识指示相应的参考信号，而网络设备将使用与发送该参考信号时的发送波束一样的发送波束，来发送数据或信号。那么相应的，终端可以使用与接收该参考信号时的接收波束一样的接收波束，来接收数据或信号。
在一些实施例中，QCL type D可以用于指示目标接收波束的接收波束信息。其中，目标接收波束可以认为是终端接收网络设备发送的某一个参考信号所使用的接收波束。当然，该目标接收波束也可以认为是网络设备基于波束预测模型预测得到的优选波束中的接收波束。例如可以是优选接收波束，或者是优选波束对中的优选接收波束。
可以理解，本公开所涉及的波束预测模型可以是上述提到的AI模型。
终端可以基于网络设备发送的波束指示信息所指示的目标接收波束，接收网络设备发送的与该波束指示信息对应的数据/信号。该波束指示信息用于指示终端接收网络设备发送的数据/信号时对应的目标接收波束。
