Description

一种干扰测量方法、 系统、 相关设备及存储介质 技术领域
本发明涉及无线通信技术, 尤其涉及一种干扰测量方法、 系统、 相关 设备及存储介质。 背景技术
长期演进( LTE, Long Term Evolution )系统是第三代伙伴组织( 3GPP, 3rd Generation Partnership Project ) 的重要计划。 LTE系统釆用常规循环前 缀(CP, Cyclic Prefix ) 时, 一个时隙中包含 7个长度的下行符号; LTE系 统釆用扩展 CP时, 一个时隙中包含 6个长度的下行符号。
图 1是根据相关技术的 LTE系统物理资源块(PRB, Physical Resource Block ) 的示意图。 如图 1所示, 一个资源单元(RE, Resource Element ) 为一个 OFDM符号中的一个子载波,而一个下行 RB由连续的 12个子载波 和连续的 7 个 (扩展循环前缀的时候为 6 个)正交频分复用 (OFDM, Orthogonal Frequency Division Multiplexing )符号构成。 一个資源块在频域 上为 180kHz, 时域上为一个时隙的时间长度。 进行资源分配时, 会以一个 子帧 (对应两个时隙)上的两个资源块(也称为物理资源块对) 为基本单 位来进行分配。
在 LTE系统中定义了如下几种下行物理信道:
物理广播信道(PBCH, Physical Broadcast Channel ): 该信道承载的信 息包括: 系统的帧号、 系统的下行带宽、 物理混合重传信道的周期、 以及 用于确定物理混合自动重传请求指示信道(PHICH, Physical Hybrid ARQ Indicator Channel )信道组数的参数 e {1/6, 1/2,1, 2} .
物理多播信道( PMCH, Physical Multicast Channel ): 主要用于支持多 播单频网络 ( MBSFN, Multicast Broadcast over Single Frequency Network ) 业务, 将多媒体时频信息向多用户广播。 PMCH 只能在 MBSFN 子帧和 MBSFN区域传输;
物理下行共享信道 ( PDSCH, Physical Downlink Shared Channel ): 用 于承载下行传输数据;
物理下行控制信道( PDCCH, Physical Downlink Control Channel ): 用 于承载上、 下行调度信息, 以及上行功率控制信息。 在 LTE R8、 R9和 R10 中的 PDCCH主要分布在一个子帧的前 1、2、3或 4个正交频分复用( OFDM, Orthogonal Frequency Division Multiplexing )符号, 具体分布需要按照不同 的子帧类型和公共参考信号( C S, Common Reference Signal或 Cell-specific Reference Signal )的端口数目来配置。 如表格 1所示, 分别给出了按照不同 的子帧类型和 CRS的端口数目配置的下行资源块数目 (^™ )大于 10和不 大于 10的 PDCCH占用的 OFDM符号数目:
Figure imgf000004_0001
表 1
物理控制格式指示信道 ( PCFICH, Physical Control Format Indicator
Channel ): 承载的信息用于指示在一个子帧里传输 PDCCH的 OFDM符号 的数目, 在子帧的第一个 OFDM符号上发送, 所在频率位置由系统下行带 宽与小区标识(Identity, 简称为 ID )确定; PHICH: 用于承载上行传输数据的肯定应答 /否定应答(ACK/NACK ) 反馈信息。 PHICH的数目、 时频位置可由 PHICH所在的下行载波的物理广 播信道( PBCH, Physical Broadcast Channel )中的系统消息和小区 ID确定。
为获得更高的频 i "效率提升, 小区部署密度越来越高, 同小区中用户 干扰(如图 2所示)及小区间的共道干扰(如图 3所示)越来越成为限制 网络容量的主要因素。
在当前的研究中, 主要是通过网络侧的预编码、 协作调度等方式, 在 发送侧实现干扰压缩。 然而, 这种基于网络侧的干扰协作, 在很大程度上 依赖于反馈的信道状态信息 (CSI, Channel State Information ) 的精确度。 根据相关研究资料表明, 釆用先进的接收方法也可以很好地压缩干扰, 同 时相对于发送方的干扰协作, 基于终端的增强可以緩解信道信息反馈的压 力。 因此如何通过优化终端接收以更好地压缩干扰, 是有效提高频谱效率 的一个重要方向。
在 LTE Release 8系统中, 釆用的是公共参考信号 ( CRS, Cell-specific Reference Signal )对 PDCCH/PDSCH 进行信道质量信息 (CQI, Channel Quality Information )测量和信道解调。 由于 CRS是小区特定的信号, 因此 同一小区的所有终端使用相同的 CRS资源。不同小区的 CRS信号所占用资 源有可能是错开的,即不同小区具有相同的"^值;也有可能是完全重叠的, 即不同小区具有不同的值。 其中 《与小区标识 ^ 11有关, 满足 v SMf. = l mod 6 o 如图 4和图 5分别示出了 CRS在常规 CP和扩展 CP情况 下的一种资源配置示意图 ( v = () )。 釆用基于 CRS的预编码处理方式需要 发射端额外通知接收端数据发送时所使用的预编码权值信息, 而且导频的 开销较大。 另外在多用户多输入多输出( MU-MIMO, Multi-user Multi-input Multi-output ) 系统中, 由于多个终端使用相同的 CRS资源, 无法实现导频 的正交, 导致多用户传输情况下目标数据信道估计性能受限。 在增强的长期演进( LTE-A, Advanced Long Term Evolution ) 系统中, 为了降低导频开销和提高信道估计准确度, 将导频测量和数据解调功能分 开, 分别定义了两类参考信号: 解调参考信号 (DM S, Demodulation Reference Signal ) 和信道状态信息参考信号 ( CSI-RS, Channel State Information Reference Signal )。 其中 DMRS 主要用于物理下行共享信道 ( PDSCH, Physical Downlink Shared Channel ) 以及增强的物理下行控制信 道 ( ePDCCH, enhanced Physical Downlink Control Channel ) 的信道估计以 完成数据 /控制信道的解调, DMRS的传输携带了相应 PDSCH/ePDCCH的 预编码信息。 CSI-RS主要用于信道测量以获得 CQI并反馈, 使基站侧可以 利用该信息完成用户调度以及完成调制编码方案 (MCS, Modulation and Coding Scheme )的自适应分配, CSI-RS的传输中并不携带预编码信息。 其 中 CSI-RS中还包含一类特殊的 CSI-RS信号称之为零功率信道状态信息参 考信号 ( ZP-CSI-RS, Zero Power Channel State Information Reference Signal ), 被确定为用于 ZP-CSI-RS的资源上发送零功率信号。 ZP-CSI-RS的主要是 为了保证小区间 CSI-RS的正交, 避免小区间 CSI-RS与 PDSCH之间的干 扰。同时,在 LTE Release 11阶段又引入了信道状态信息干扰测量( CSI-IM, Channel State Information Interference Measurement )信号, 主要用于提高信 道 CQI干扰测量性能。
但是, 关于如何提高 PDCCH/ePDCCH/PDSCH信道解调情况下的干扰 测量性能, 目前尚未提出有效解决方案。 发明内容
