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,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也可以称作终端设备或者UE,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)、可穿戴式设备(Wearable Device)或车载设备(Vehicle User Equipment,VUE)、行人终端(Pedestrian User Equipment,PUE)等终端侧设备,可穿戴式设备包括:智能手表、手环、耳机、眼镜等。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可以是基站或核心网设备,其中,基站可被称为节点B、演进节点B、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)、B节点、演进型B节点(eNB)、家用B节点、家用演进型B节点、无线局域网(Wireless Local Area Network,WLAN)接入点、WiFi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,但是并不限定基站的具体类型。
为了方便理解,以下对本申请实施例涉及的一些内容进行说明:
一、SFN传输方式。
在SFN网络部署下,多个远程射频单元(Remote Radio Head,RRH)会连接在一个室内基带处理单元(Building Base band Unite,BBU)上,这样终端在高速移动的过程中就不需要频繁切换基站。同时,多个RRH发送相同的数据给终端。
由于终端与多个RRH位置关系不同,导致多个RRH的传输信号到达终端的功率、时延、相位和多普勒频移不同。当UE在铁轨上处于不同的位置,则传输给UE的SFN信号将经历完全不同的信道特征。尤其当来自两个RRH的SFN信号到达UE的时延较大时,SFN信号可能经历严重的频域深衰。另外,当UE在两个RRH之间高速运动时,会导致接收信号中存在两个符号相反的多普勒频偏影响,从而SFN信号的时域深衰。
二、信道状态信息(Channel State Information,CSI)上报框架。
在NR的CSI上报框架中,通过CSI报告(用于上报)关联CSI资源(用于测量)的形式来进行。
CSI报告可以配置为以下三种类型:
周期CSI报告(P-CSI):仅在物理上行控制信道(Physical Uplink Control Channel,PUCCH)上传输;
半持续CSI报告(SP-CSI):在PUCCH或物理上行共享信道(Physical Uplink Shared Channel,PUSCH)上传输;
非周期CSI报告(AP-CSI):仅在PUSCH上传输。
CSI资源配置(resource setting/CSI-ResourceConfig)如下:
M≥1个资源配置(resource setting);
一个资源配置包含S≥1个CSI资源集(resource set);
一个资源集包含Ks≥1个CSI资源,包括CSI参考信号(CSI Reference Signal,CSI-RS)和CSI干扰测量(CSI Intereference Measurement,CSI-IM)等。
三、基于PUSCH的CSI上报。
基于PUSCH的CSI上报支持类型I(TypeI)宽带或者子带CSI,同时也支持类型II(TypeII)CSI。
对于基于PUSCH的TypeI,TypeII和增强的TypeII CSI,一个CSI报告(report)由两部分组成(第一部分(Part1)和第二部分(Part2)),其中CSI第一部分(CSI Part1,也可以称之为Part1)有一个固定的负载大小,并指示CSI第二部分(CSI Part2,也可以称之为Part2)的信息比特(bit)的数量。对于TypeI CSI反馈:Part1可能包括秩指示(Rank indicator,RI)、CSI参考信号资源指示(CSI-RS Resource Indicator,CRI)、第一码字的信道质量指示(Channel quality indicator,CQI)中的一个或者多个;Part2包含预编码矩阵指示(Precoding matrix indicator,PMI)和第二码字的CQI中的一项或者多项。
对于TypeII CSI反馈:Part1包括RI、CQI和TypeII CSI每层非零宽带幅度系数指示中的一项或者多项,Part2包含TypeII CSI的PMI。
对于增强的TypeII CSI反馈:Part1包括RI、CQI、增强型TypeII CSI跨层非零振幅系数的总数的指示,TypeII包含增强型TypeII CSI的PMI。
当基于PUSCH报告的CSI包含Part1和Part2时,UE可以删除部分Part2内容,Part2的删除规则按照优先级从高到低的顺序。
其中,对于增强型TypeII CSI报告,组0(Group 0)包括索引i1,1、i1,2和i1,8,l(l=1,…,v);组1(Group1)包含索引i1,5(如果上报)、i1,6,l、高优先级的部分i1,7,l、i2,3,l、高优先级的部分i2,4,l和高优先级的部分i2,5,l(l=1,…,v);组2(Group2)包括低优先级的部分i1,7,l、低优先级的部分i2,4,l和低优先级的部分i2,5,l(l=1,…,v)。
四、基于PUCCH的CSI上报。
基于PUCCH格式(format)2、3、4的周期CSI上报支持宽带TypeI CSI;
基于PUCCH的半持续CSI上报支持TypeI CSI;
基于PUCCH format 2的半持续CSI上报支持宽带TypeI CSI;
基于PUCCH format 3或4的半持续CSI上报支持宽带和子带TypeI CSI,以及TypeII CSI Part1;
对于子带TypeI CSI,并基于PUCCH format 3或4上报的情况,CSI负载可以分为两部分(Part1和Part2)。Part1包括RI、CRI、第一码字对应的CQI中的部分或者全部,Part2包括PMI和第二码字对应的CQI。
若一个CSI report包含Part1和Part2两部分,UE可以删除部分Part2的内容,优先级顺序与基于PUSCH上报的优先级表格一致。
下面结合附图,通过一些实施例及其应用场景对本申请实施例提供的信道状态信息CSI上报处理方法进行详细地说明。
请参见图2,图2是本申请实施例提供的一种信道状态信息CSI上报处理方法的流程图,如图2所示,包括以下步骤:

可选地,上述第一CSI可以与其他CSI上报信息在同一个CSI报告中进行上报。例如,在一些实施例中,所述第一CSI上报信息还包括第二CSI,所述第二CSI信息包括以下至少一项:信道状态信息参考信号资源指示CRI、秩指示RI、层指示LI、预编码矩阵指示PMI和信道质量指示CQI。

本申请实施例中,N的具体取值可以由网络侧设备进行指示或者按照默认规则约定。应理解,在终端进行CSI报告的上报时,CSI报告对应的单发送接收点传输和SFN传输并未实际发生,因此该传输可以理解为传输假设。换句话说,上述第一上报方式可以理解为终端在一个CSI报告中同时上报,N个单发送接收点传输假设各自对应的CSI上报信息,以及一个SFN传输假设对应的CSI上报信息,网络侧设备可根据终端上报的CSI报告决定在后续的传输中采用单发送接收点传输方式或者SFN传输方式;上述第二上报方式可以理解为终端在一个CSI报告中上报:N个单发送接收点传输假设和一个SFN传输假设中的目标传输假设所对应的CSI上报信息,目标传输假设为最优传输假设。
