Description
本发明涉及通信领域,具体而言,涉及一种信道状态测量导频的配置方法及装置、解析方法及装置。
长期演进(Long Term Evolution,简称为LTE)/长期演进升级(LTE-Advanced,简称为LTE-A)技术是主流的第四代移动通信技术(4G)。LTE/LTE-A分以下两种不同的双工方式:频分双工方式(Frequency Division Duplex,简称为FDD)、时分双式方式(Time Division Duplex,简称为TDD)。频分双工方式的帧结构称为第一类型帧结构(Frame structure type 1),时分双工方式的帧结构称为第二类型帧结构(Frame structure type 2)。
图1为相关技术中第一类型帧结构的示意图,如图1所示,第一类型帧结构的说明如下:每个无线帧(radio frame)长为Tf=307200·Ts=10ms(毫秒),由20个时隙(slot)构成,时隙的长度为Tslot=15360·Ts=0.5ms(毫秒),编号从0到19,其中,Ts为时间单位,Ts=1/(15000×2048)秒;子帧(subframe)被定义为由两个连续的时隙构成,即子帧i由时隙2i与2i+1构成;对于FDD双工方式,在10毫秒时间间隔里,10个子帧用于下行传输,10个子帧用于上行传输;上行传输与下行传输分别在不同的频率上进行,在半双工(half-duplex)FDD方式下,终端(User Equipment,简称为UE)不能同时传输与接收,而在全双工FDD方式下,没有这种限制。
图2为相关技术中第二类型帧结构的示意图,如图2所示,第二类型帧结构的说明如下:每个无线帧(radio frame)长为Tf=307200·Ts=10ms,由两个半帧(half-frame)构成,半帧长度为153600·Ts=5ms,每个半帧由5个子帧(subframe)构成,每个子帧长度为30720·Ts=1ms,每个子帧定义为两个时隙(slot)构成,即子帧i由时隙2i与2i+1构成,时隙长度为Tslot=15360·Ts=0.5ms,其中,Ts为时间单位,Ts=1/(15000×2048)秒。
一个小区的上下行配置(uplink-downlink configuration)变化发生在帧之间,上下行传输发生在帧的子帧上。当前帧的上下行配置由高层信令得到。
表1所示的上下行配置(uplink-downlink configuration)共有7种,对于一个无线帧中的每一个子帧,“D”标记一个下行子帧,用于下行传输,“U”标记一个上行子帧,用于上行传输,“S”标记一个特殊子帧。特殊子帧有以下三个区域:下行导频时隙(DwPTS)、保护间隔(GP,Guard Period)以及上行导频时隙(UpPTS),如表1所示;
表1
LTE/LTE-A技术下行传输采用正交频分复用(Orthogonal Frequency Division Multiplexing,简称为OFDM)调制技术,数据调制在频域的子载波(subcarrier)上,然后转换到时域增加上循环前缀构成一个完整的时域发射OFDM符号。循环前缀(Cyclic Prefix,简称为CP)用以抵抗多径在时域上产生的符号干扰以及在频域上产生的子载波间干扰。在LTE/LTE-A系统中有两种长度的CP,一种为正常CP(Normal Cyclic Prefix,简称为NCP),另一种为扩展CP(Extended Cyclic Prefix,简称为ECP)。扩展CP应用在多径时延扩展更大的场景下。正常CP情况下,子载波间隔为15kHz;扩展CP情况下,子载波间隔有两种,分别为15kHz与7.5kHz。
每个时隙传输的信号用一个或多个资源网格(resource grid)描述,资源网格由个子载波与个OFDM符号(OFDM symbol)构成。其中,代表物理资源块(Physical Resource Block,简称为PRB)或资源块(Resource Block,简称为RB)的数目,代表资源块中子载波的数目,代表时隙中OFDM符号数目。表2所示为物理资源块参数,在一个RB上的OFDM符号数目与子载波数目如表2所示。表3所示为OFDM符号参数,循环前缀的长度如表3所示。
表2
表3
同一个子帧上连续两个时隙上的同一个PRB,称为一个PRB对(PRB pair)。
图3为相关技术中下行资源网格的示意图,如图3所示,资源网格中的每个单元称为资源单元(Resource Element,简称为RE),并用索引对(k,l)标记,其中,表示频域上子载波序号,表示时域上的OFDM符号序号。
天线端口定义为在这个天线端口上传输的符号所通过的信道,可以由这个相同端口上传输的其它符号所通过的信道推测。一个天线端口还定义有对应的序号,以进行天线端口之间的区分以及该天线端口的索引。
下行物理信道(Downlink Physical Channel)对应着一些资源单元的集合,用以承载来自于上层的信息。下行物理信息包括:物理下行共享信道(Physical Downlink Shared Channel,简称为PDSCH)、物理多播信道(Physical Multicast Channel,简称为PMCH)、物理广播信道(Physical Broadcast Channel,简称为PBCH)、物理控制格式指示信道(Physical Control Format Indicator Channel,简称为PCFICH)、物理下行控制信道(Physical Downlink Control Channel,简称为PDCCH)、物理混合自动重传请求指示信道(Physical Hybrid ARQ Indicator Channel,简称为PHICH)、增强物理下行控制信道(Enhanced Physical Downlink Control Channel,简称为EPDCCH)。
下行物理信号(Downlink Physical Signal)对应着一套资源单元集合,由物理层使用,不用于承载上层信息。下行物理信号包括:导频信号(Reference Signal,简称为RS)、同步信号(Synchronization signal)、发现信号(Discovery signal)。
导频信号也称为导频,有以下种类:小区导频(Cell-specific Reference Signal,简称为CRS)、多播/组播单频网络(Multimedia Broadcast Single Frequency Network,简称为MBSFN)导频(MBSFN reference signals)、UE专用导频(解调导频(Demodulation Reference Signal,简称为DMRS))、定位导频(Positioning reference signal)、信道状态测量导频(CSI reference signal,简称为CSI-RS);其中,UE专用导频又有以下两类:解调PDSCH的UE专用导频(UE-specific reference signals associated with PDSCH)、解调EPDCCH的UE专用导频(Demodulation reference signals associated with EPDCCH)。
信道状态测量导频(CSI-RS)用于终端预测信道状态。采用非零功率发射的CSI-RS,称为非零功率CSI-RS(NZP CSI-RS);有时为了避免产生干扰,需要避免PDSCH上一些RE上的数据发射,而采用零功率发射CSI-RS方式实现,此时称为零功率CSI-RS(ZP CSI-RS),对应的资源单元集合为零功率CSI-RS资源(Zero Power CSI-RS Resource)。有时为了测量干扰,采用零功率发射CSI-RS,此时对应的资源单元集合称为干扰测量资源(CSI-IM Resource,Channel-State Information-Interference Measurement Resource)。
CSI-RS配置(CSI reference signal configuration)用以指示CSI-RS所映射的RE,即传输CSI-RS所使用的RE,CSI-RS配置序号用以区分不同的CSI-RS配置。传输或映射一种CSI-RS配置下CSI-RS的RE集合称为CSI-RS资源图案。CSI-RS子帧配置(CSI reference signal subframe configuration)用以指示CSI-RS传输所在子帧。
一种CSI-RS配置是一定天线端口数目下的CSI-RS配置,例如天线端口数目为8的配置序号为0的CSI-RS配置。一种CSI-RS资源图案是一定天线端口数目下的CSI-RS资源图案,例如天线端口数目为8的索引号为0的CSI-RS资源图案。通常配置序号就是索引号。
一种CSI-RS配置下传输或映射部分端口的CSI-RS的RE集合称为部分端口导频资源图案,例如端口序号为{15,16,17,18}的端口导频资源图案。
现有技术支持端口数目为1,2,4,8的CSI-RS,这些端口数目的CSI-RS资源图案在传输子帧上在带宽范围的每一个PRB对上重复。
不同端口数目的所有配置CSI-RS资源图案的RE集合相同,即端口数目为2的所有配置CSI-RS资源图案的RE集合等于端口数目为4的所有配置CSI-RS资源图案的RE集合,等于端口数目为8的所有配置CSI-RS资源图案的RE集合。例如,对于第一类型帧结构与第二类型帧结构共同的CSI-RS配置情况,不同端口数目的所有配置CSI-RS资源图案的RE集合相同,在一个PRB对上的RE数目为40。
图4为相关技术中端口数目为4的CSI-RS在一个RB对上的资源图案的示意图;图5为相关技术中端口数目为8的CSI-RS在一个RB对上的资源图案的示意图。
为了充分利用功率及提高信道测量的精度,还把各端口的CSI-RS划分到小组,即一个小组内包括多个端口的CSI-RS,具有一至多个数目不等的小组。小组内各端口的CSI-RS采用码分复用的方式映射到一组共同的RE上。例如,小组内端口数目为N,CSI-RS序列为{r0,r1,...,rN-1};另有长度为N的序列组其中,p=K+0,K+1,…,K+N-1,组内有N条序列,组内序列之间相互正交,即其中,i,j=K+0,K+1,…,K+N-1,并且i≠j;CSI-RS序列{r0,r1,...,rN-1}对序列进行调制得到端口为p的CSI-RS序列对应于一组共同的RE,将端口为p的CSI-RS序列中元素一一对应映射到RE。N即为复用的长度。
现有技术中,端口之间CSI-RS复用映射到RE的方式如下:将端口划分为小组,如{15,16}、{17,18}、{19,20}、{21,22}共计4个小组,这4个小组之间以频分方式复用到RE上;而小组内端口上的CSI-RS则在时域上以码分方式复用到RE上,例如端口15的CSI-RS与端口16的CSI-RS在时域上以码分方式复用。
基站通过上层信令通知终端关于CSI-RS的信息,这些信息包括:CSI-RS资源配置识别号(CSI-RS resource configuration identity)、CSI-RS端口数目、CSI-RS配置、CSI-RS子帧配置。
CRS既可用于对信道状态的测量,也可用于接收解调时对信道系数的估算,但随着端口数目的增多,开销急剧增大。所以,端口数目为8的情况下不再使用CRS对信道状态进行测量,而改用导频密度低、开销少的CSI-RS。但是随着技术与需求的发展,需要进一步开发更大数目天线端接应用的技术,例如端口数目为12、16等,其中涉及到对这些更大数目端口信道状态的测量。当前传输大数目端口信道测量导频的方法是采用聚合多个小数目端口信道测量导频。例如采用K个N端口的信道测量状态导频聚合K*N个端口的信道测量状态导频,其中*为乘号。比如,(N,K)=(8,2)的方式聚合16个端口的信道测量状态导频。
但是聚合后的导频端口的排序方式或导频端口编号对信道测量反馈的性能影响较大。天线端口之间的位置关系或极化属性关系不同,对应的信道系数关系特征不一样,码字元素之间的关系在反映端口信道系数之间的关系的同时,也反映了天线端口之间的位置关系或极化属性关系。
针对相关技术中的上述问题,目前尚未存在有效的解决方案。
