Description

在大带宽系统中数据传输的方法
技术领域
本发明涉及移动无线通信领域， 尤其涉及一种在大带宽系统中数据传输 的方法。
背景技术
LTE ( Long Term Evolution, 长期演进) 系统 FDD ( Frequency Division Duplex, 频分双工 )模式的帧结构中， 一个 10ms的 radio frame (无线帧 ) 由 二十个长度为 0.5ms, 编号 0~19的 slot (时隙 )组成， 时隙 2i和 2i+l组成长 度为 1ms的 subframe (子帧） i, 如图 1所示。 LTE系统 TDD ( Time Division Duplex, 时分双工 )模式的帧结构中， 一个 10ms的 radio frame (无线帧 ) 由 两个长为 5ms的 half frame(半帧）组成，一个半帧包含 5个长为 1ms的 subframe (子帧） ， 子帧 i定义为 2个长为 0.5ms的时隙 2i和 2i+l , 如图 2所示。 两 种帧结构里， 对于 Normal CP ( Normal Cyclic Prefix, 标准循环前缀） , 一个 时隙包含 7个长度为 66.7us的符号，其中第一个符号的 CP长度为 5.21us,其 余 6个符号的 CP长度为 4.69us; 对于 Extended ( Extended, 扩展） CP, —个 时隙包含 6个符号， 所有符号的 CP长度均为 16.67us。
LTE定义了 PDCCH ( Physical downlink control channel, 物理下行控制信 道） 7 载调度分配和其它控制信息； PCFICH ( Physical control format indicator channel, 物理控制格式指示信道）承载在一个子帧里用于传输 PDCCH 的 OFDM符号的数目信息， 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 ID决定。
LTE Release-8定义了 6种带宽： 1.4MHz、 3MHz、 5MHz、 10MHz、 15MHz 和 20MHz。
LTE- Advanced ( Further Advancements for E-UTRA )是 LTE Release-8的 演进版本。 除满足或超过 3GPP TR 25.913: "Requirements for Evolved UTRA ( E-UTRA ) and Evolved UTRAN ( E-UTRAN ) " 的所有相关需求外， 还要 达到或超过 ITU-R (无线通信部门）提出的 IMT-Advanced (高级国际移动通 信） 的需求。 其中， 与 LTE Release-8后向兼容的需求是指： LTE Release-8 的终端可以在 LTE-Advanced的网络中工作； LTE-Advanced的终端可以在 LTE Release-8的网络中工作。
另夕卜， LTE-Advanced应能在不同大小的载频（carrier, 也称为频语） 配 置， 包括比 LTE Release-8更宽的载频配置 （如 100MHz的连续的载频资源 ) 下工作， 以达到更高的性能和目标峰值速率。 在本文中， "大带宽系统" 即 指具有比 LTE Release-8更宽的载频（超过 20MHz ) 的 LTE-Advanced系统。 考虑到与 LTE Release-8的兼容性， 载频配置的方案主要有 3种， 如图 3 ~ 5 所示。 其中， 方格部分为与 LTE Release-8 兼容的系统带宽， 斜线部分为 LTE-Advanced专有的系统带宽。 图 3为载频配置方案 1 , 是指 LTE-Advanced 载频配置由 1 个 LTE-Advanced定义的系统带宽组成， 且该带宽大于 LTE Release-8定义的系统带宽。 图 4为载频配置方案 2, 是指 LTE-Advanced载频 配置由一个 LTE Release-8定义的系统带宽和多个 LTE-Advanced定义的系统 带宽通过载频聚集（ carrier aggregation )组成。 图 5为载频配置方案 3 , 是指 LTE-Advanced载频配置由多个 LTE Release-8定义的系统带宽通过载频聚集 组成， 其中， 上述载频的聚集可以是连续载频的聚集， 也可以是不连续载频 的聚集。
对于聚集后的载频， 被划分为 n个分量载频（Component carrier ) , 每个 分量载频内的载频是连续的；
LTE-Advanced系统中， 物理信道所承载的数据， 比如 LTE-Advanced终 端（UE, User Equipment )专有的 PDCCH信道所承载的下行控制信息（DCI
, Downlink Control Information ) , 可以在一个分量载频内发送， 也可以在多个 分量载频内发送； 如果， 物理信道所承载的数据在一个或几个固定分量载频 上发送， 那么， 就无法获得最大的频率选择性增益， 而且， 系统容量和调度 的灵活性都受到限制。 发明内容

进一步地， 所述步骤（2 )中， 在数据重传的时候， 基站可重新配置重传 数据所在的分量载频。
进一步地， 所述步骤（2 ) 中， 在半静态调度业务数据每次传输的时候， 基站可重新配置半静态调度业务数据所在的分量载频。
进一步地， 所述半静态调度业务可以为语音业务。
