具体实施方式
为了便于理解，首先介绍本申请涉及的术语。
1、下行控制信息(downlink control information，DCI)
DCI由物理下行控制信道(physical downlink control channel，PDCCH)承载，DCI可以包括上下行资源分配、混合自动重传请求(hybrid automatic repeat request，HARQ)信息、功率控制等。PDCCH是一种物理信道，用于承载所述下行控制信息。
2、波束beam指示
Rel-16中，可以指示物理下行控制信道PDCCH、物理下行共享信道(physical downlink share channel，PDSCH)、物理上行控制信道(physical uplink control channel，PUCCH)、物理上行共享信道(physical uplink share channel，PUSCH)和/或参考信号(reference signal，RS)等对应的波束。
所述参考信号RS包括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)，定位参考信号(positioning reference signal，PRS)，相位参考信号(tracking reference signal，TRS)等，所述CSI-RS包括用于信道状态信息测量的CSI-RS、或用于波束测量的CSI-RS、或用于信道损失pathloss估计的CSI-RS；SRS包括用于基于码本codebook或非码本non-codebook的信道状态信息测量的SRS或用于波束测量的SRS或用于定位测量的SRS。
本文所述的波束也称为传输配置指示(transmission configuration indicator，TCI)状态(state)。其中TCI state包含准共址(Quasi Co-location，QCL)Type D信息。本文所述的波束应用时间也称为TCI state的应用时间。
为了更好的理解本申请实施例公开的一种波束应用的方法，下面首先对本申请实施例适用的通信系统进行描述。
请参见图1，图1为本申请实施例提供的一种通信系统的架构示意图。该通信系统可包括但不限于一个网络设备和一个终端设备，图1所示的设备数量和形态仅用于举例并不构成对本申请实施例的限定，实际应用中可以包括两个或两个以上的网络设备，两个或两个以上的终端设备。图1所示的通信系统以包括一个网络设备101和一个终端设备102为例。
需要说明的是，本申请实施例的技术方案可以应用于各种通信系统。例如：长期演进(long term evolution，LTE)系统、第五代(5th generation，5G)移动通信系统、5G新空口(new radio，NR)系统，或者其他未来的新型移动通信系统等。还需要说明的是，本申请实施例中的侧链路还可以称为侧行链路或直通链路。
本申请实施例中的网络设备101是网络的一种用于发射或接收信号的实体。例如，网 络设备101可以为演进型基站(evolved NodeB，eNB)、传输点(transmission reception point，TRP)、NR系统中的下一代基站(next generation NodeB，gNB)、其他未来移动通信系统中的基站或无线保真(wireless fidelity，WiFi)系统中的接入节点等。本申请的实施例对网络设备所采用的具体技术和具体设备形态不做限定。本申请实施例提供的网络设备可以是由集中单元(central unit，CU)与分布式单元(distributed unit，DU)组成的，其中，CU也可以称为控制单元(control unit)，采用CU-DU的结构可以将网络设备，例如基站的协议层拆分开，部分协议层的功能放在CU集中控制，剩下部分或全部协议层的功能分布在DU中，由CU集中控制DU。
本申请实施例中的终端设备102是用户侧的一种用于接收或发射信号的实体，如手机。终端设备也可以称为终端设备(terminal)、用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端设备(mobile terminal，MT)等。终端设备可以是具备通信功能的汽车、智能汽车、手机(mobile phone)、穿戴式设备、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端设备、无人驾驶(self-driving)中的无线终端设备、远程手术(remote medical surgery)中的无线终端设备、智能电网(smart grid)中的无线终端设备、运输安全(transportation safety)中的无线终端设备、智慧城市(smart city)中的无线终端设备、智慧家庭(smart home)中的无线终端设备等等。本申请的实施例对终端设备所采用的具体技术和具体设备形态不做限定。
Rel-16中，PDCCH、PDSCH、PUSCH、PUCCH和/或参考信号等的波束都是独立指示的。所述参考信号包括CSI-RS，SRS，PRS，TRS等，CSI-RS包括用于信道状态信息测量的CSI-RS或用于波束测量的CSI-RS或用于pathloss估计的CSI-RS；SRS包括用于基于码本codebook或非码本non-codebook的信道状态信息测量的SRS或用于波束测量的SRS或用于定位测量的SRS，而且PDCCH和PUCCH使用媒体接入控制(medium access control，MAC)控制元素(control element，CE)来激活一个波束。而PDSCH和PUSCH是根据DCI信令来指示其各自的波束。目前为了减少信令开销，一种可能的方法是使用通用波束common beam，common beam目前可能是由上行传输的独立上行传输配置指示状态separate UL TCI state和下行传输的独立下行传输配置指示状态separate DL TCI state分开指示，或者由上下行的联合传输配置指示状态joint TCI state联合指示。即基站如果指示一个用于下行的common beam，那么该common beam可以用于终端设备的PDSCH和一部分/全部PDCCH，比如用户设备UE专用PDCCH；基站如果指示一个用于上行的common beam，那么该common beam可以用于终端的PUSCH和一部分/全部PUCCH。
对于DCI指示的unified TCI state，目前是提出在针对该DCI的混合自动重传请求(Hybrid Automatic Repeat Request，HARQ)确认字符(Acknowledge character，ACK)反馈发送后的T时间后，即可使用该DCI指示的unified TCI state，即波束应用时间beam application time为HARQ ACK反馈发送后的T时间后。但是目前尚缺乏对于跨载波指示时，beam application time的确定方法，无法在跨载波指示时保证所述网络设备和所述终端设备的波束一致。
可以理解的是，本申请实施例描述的通信系统是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着系统架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
下面结合附图对本申请所提供的波束应用的方法及其装置进行详细地介绍。

本公开实施例中，所述波束应用时间为开始应用所述波束的时间点，为了保证通信质量，需要使所述网络设备和所述终端设备的波束应用时间一致。在接收到所述DCI中的统一传输配置指示状态后即可确定所述统一传输配置指示状态对应的上行传输的波束应用时间和/或下行传输的波束应用时间。或

本公开实施例中，混合自动重传请求HARQ是一种将前向纠错编码(forward error correction，FEC)和自动重传请求(Automatic Repeat Request，ARQ)相结合而形成的技术。基本原理如下所示:在接收端使用FEC技术纠正所有错误中能够纠正的那一部分；进行过错误检测判断不能纠正错误的数据包；丢弃不能纠错的数据包，向发送端请求重新发送相同的数据包。混合自动重传请求HARQ所述确认字符ACK为所述接收端向发送端发送的反馈信息。所述终端设备为接收端，终端设备在向网络设备发送所述HARQ ACK时间的多个符号之后的时间为所述波束应用时间。
通过本申请实施例，实现了根据针对所述下行控制信息DCI的所述HARQ ACK反馈传输时间确定对应的上行传输的波束应用时间和/或下行传输的波束应用时间。从而保证所述网络设备和所述终端设备的波束一致，提高传输性能。
