Description

下行子帧调度方法、 基站、 终端和系统 本申请要求于 2012 年 12 月 28 日提交中国专利局、 申请号为 201210585480.3、 发明名称为"下行子帧调度方法、 基站、 终端和系统'，的中 国专利申请的优先权， 其全部内容通过引用结合在本申请中。 技术领域 本发明涉及通信领域， 特别涉及一种下行子帧调度方法、 基站、 终端 和系统。
背景技术 现有的 3GPP ( 3rd Generation Partnership Project,第三代系统合作项目 ） 的 LTE ( Long Term Evolution, 长期演进计划 )系统中， 终端根据基站下发 的 PDCCH ( Physical Downlink Control Channel, 物理下行控制信道）信令 的指示在对应的上下行资源处接收下行业务数据、 发送上行业务数据。
现有的 LTE系统中， 基站通过 PDCCH信令调度一个子帧的资源进行 业务数据的传输。对于下行业务数据的传输，基站在 PDCCH信令上发送相 应的调度指示进行下行子帧资源的调度， 并在承载调度指示的子帧上下发 业务数据。 具体地， 终端接收下行 MAC ( Medium Access Control, 媒体接 入控制）数据包后通过 CRC ( Cyclic Redundancy Check, 循环冗余校验码） 校验数据包是否正确，如果正确， 则在收到 MAC数据包后的某个固定子帧 向基站反馈正确指示， 通知基站可以开始新业务数据的调度； 如果错误， 终端在收到 MAC数据包后的某个固定子帧向基站反馈错误指示，基站收到 错误指示后对该 MAC数据包进行重传， 直到接收到终端发出的正确指示， 或达到最大重传次数后放弃重传该 MAC数据包。
随着室内 MBB ( Mobile Broadband, 移动宽带）业务需求的快速增长， 某些室内覆盖场景具有覆盖范围小、 用户数少和用户信道条件好且稳定的 特性， 按照 LTE标准， 如果每个 PDCCH信令只能调度一个或固定个数的 子帧的资源， 则需要频繁的根据数据传输格式配置终端的接收模式， 导致 系统的 PDCCH信令开销大， 频谱效率较低， 从而限制了系统容量。
