波束报告方法、装置及网络侧设备
相关申请的交叉引用
本申请主张在2021年12月13日在中国提交的中国专利申请No.202111523170.4的优先权，其全部内容通过引用包含于此。
技术领域
本申请属于通信技术领域，具体涉及一种波束报告方法、装置及网络侧设备。
背景技术
在对第四代移动通信(4th-Generation，4G)以后的下一代通信系统研究中，将系统支持的工作频段提升至6GHz以上，最高约达100GHz。高频段具有较为丰富的空闲频率资源，可以为数据传输提供更大的吞吐量。目前已经完成了高频信道建模工作，高频信号的波长短，同低频段相比，能够在同样大小的面板上布置更多的天线阵元，利用波束赋形技术形成指向性更强、波瓣更窄的波束。因此，将大规模天线和高频通信相结合，也是未来的趋势之一
。
当网络部署了不同基站采用不同的时分双工(Time Division Duplex，TDD)配置时，在同一时刻不同的基站可能处于下行(DownLink，DL)传输或者上行(UpLink，UL)接收状态。此时，进行DL传输的基站会对进行UL接收的基站产生交叉链路(cross link)干扰。当基站采用全双工(Full duplex)模式时，相邻基站之间的cross link将变得更加复杂。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的术语在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”所区别的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”一般表示前后关联对象是一种“或”的关系。
值得指出的是，本申请实施例所描述的技术不限于长期演进型(Long Term Evolution，LTE)/LTE的演进(LTE-Advanced，LTE-A)系统，还可用于其他无线通信系统，诸如码分多址(Code Division Multiple Access，CDMA)、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 Frequency Division Multiple Access，SC-FDMA)和其他系统。本申请实施例中的术语“系统”和“网络”常被可互换地使用，所描述的技术既可用于以上提及的系统和无线电技术，也可用于其他系统和无线电技术。以下描述出于示例目的描述了新空口(New Radio，NR)系统，并且在以下大部分描述中使用NR术语，但是这些技术也可应用于NR系统应用以外的应用，如第6代(6th Generation，6G)通信系统。
图1示出本申请实施例可应用的一种无线通信系统的框图。无线通信系统包括终端11和网络侧设备12。其中，终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant，PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer，UMPC)、移动上网装置(Mobile Internet Device，MID)、增强现实(augmented reality，AR)/虚拟现实(virtual reality，VR)设备、机器人、可穿戴式设备(Wearable Device)、车载设备(Vehicle User Equipment，VUE)、行人终端(Pedestrian User Equipment，PUE)、智能家居(具有无线通信功能的家居设备，如冰箱、电视、洗衣机或者家具等)、游戏机、个人计算机(personal computer，PC)、柜员机或者自助机等终端侧设备，可穿戴式设备包括：智能手表、智能手环、智能耳机、智能眼镜、智能首饰(智能手镯、智能手链、智能戒指、智能项链、智能脚镯、智能脚链等)、智能腕带、智能服装等。需要说明的是，在本申请实施例并不限定终端11的具体类型。网络侧设备12可以包括接入网设备或核心网设备，其中，接入网设备也可以称为无线接入网设备、无线接入网(Radio Access Network,RAN)、无线接入网功能或无线接入网单元。接入网设备可以包括基站、无线局域网(Wireless Local Area Network，WLAN)接入点或无线保真(Wireless Fidelity，WiFi)节点等，基站可被称为节点B、演进节点B(eNB)、接入点、基收发机站(Base Transceiver Station，BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、家用B节点、家用演进型B节点、发送接收点(Transmitting Receiving  Point，TRP)或所述领域中其他某个合适的术语，只要达到相同的技术效果，所述基站不限于特定技术词汇，需要说明的是，在本申请实施例中仅以NR系统中的基站为例进行介绍，并不限定基站的具体类型。
下面对本申请实施例提及的一些操作进行解释：
对于上行波束指示，基站指示用户设备(User Equipment，UE，或称终端)在UL调度资源上采用的波束方向，波束方向由SRS资源指示(SRS resource indicator，SRI)表示；对于下行波束指示，基站指示DL调度资源上的波束方向，以便UE能够判断其接收波束。下行波束方向由关联的传输配置指示(Transmission Configuration Indicator，TCI)指示，其中TCI反映CSI-RS资源指示(CSI-RS Resource Indicator，CRI)，同步信号块(Synchronization Signal Block，SSB)索引等信息。
为了实现灵活的网络部署，NR系统中通过时隙格式(slot format)的方式配置一个时隙中各个符号的传输方向。
NR中时隙的传输方向有三种定义，下行(DL)、上行(UL)、灵活(flexible)。当网络配置了一个时隙或符号是DL或UL，则该时刻的传输方向是明确的；当网络配置了一个时隙或符号是flexible，则该时刻的传输方向是待定的。网络可以通过动态信令，如动态时隙格式指示(dynamic slot format indicator，dynamic SFI)来对flexible的时隙或符号的传输方向进行修改。
一个时隙(slot)可以包含下行(downlink)，上行(uplink)和灵活(flexible)的正交频分复用(Orthogonal frequency division multiplex，OFDM)符号；Flexible符号可以被改写为下行或者上行符号。
SFI可以指示一个或者多个slot的格式。
SFI可以灵活地根据需求改变slot的格式，以满足业务传输需求。
UE根据SFI的指示决定是否监测物理下行控制信道(Physical downlink control channel，PDCCH)。
版本18(Release 18，Rel-18)网络侧灵活/全双工(flexible/full duplex)以及用户/终端侧半双工操作的特点：
对于频分双工(Frequency Division Duplexing，FDD)的对称频谱：FDD的上行或下行频谱：在某些时隙/符号上可以半静态地配置或动态地指示为下 行或上行传输。
对于时分双工(Time Division Duplexing，TDD)的非对称频谱：TDD某些时隙/符号上的不同频域资源可以半静态地配置或动态地指示为既有上行传输又有下行接收。
对于半双工的终端，在同一时刻只能进行上行发送或者下行接收，即在同一时刻终端不能既接收又发送信号。
