Description

信息的传输方法及相关装置
本申请要求于2016年3月31日提交中国专利局、申请号为201610200286.7、发明名称为“信息的传输方法及相关装置”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
本申请涉及通信领域,特别涉及一种信息的传输方法及相关装置。
背景技术
5G通信系统致力于支持更高系统性能,其将支持各种不同业务,不同部署场景和不同频谱。其中,不同业务包括增强的移动宽带(英文:enhanced Mobile Broadband,缩写:eMBB),机器类型通信(英文:Machine Type Communication,缩写:MTC),超可靠低延迟通信(英文:Ultra-reliable and low latency communications,缩写:URLLC),多媒体广播多播业务(英文:Multimedia Broadcast Multicast Service,缩写:MBMS)和定位等。不同部署场景包括室内热点(英文:Indoor hotspot),密集城区(英文:dense urban),郊区,城区宏覆盖(英文:Urban Macro)及高铁场景等。5G将支持高达100GHz的频谱范围,其中6GHz和6GHz以下为主频带,6GHz以上为辅频带。
不同业务、不同部署场景和不同频谱具有不同的特征,他们各自对系统参数(numerology)的要求不一样。为使得5G能够高性能支持不同业务、不同部署场景和不同频谱,5G将支持多套系统参数。
5G通信系统对应的帧结构不仅包括现有LTE系统中的下行子帧、上行子帧和特殊子帧,还会引入自包含子帧(英文:Self-contained Subframe)类型,该自包含子帧类型可以为第一子帧类型S1和/或第二子帧类型S2。S1子帧类型和S2子帧类型均包括用于下行传输的符号、保护间隔(英文:Guard Period,缩写:GP)和用于上行传输的符号,其中S1子帧中用于下行传输的符号主要用于下行控制信道传输和下行数据传输,用于上行传输的符号主要用于上行控制信息和信道探测参考信号(英文:Sounding Reference Signal,缩写:SRS)传输;而S2子帧中用于下行传输的符号主要用于下行控制信道传输,上行传输的符号主要用于上行数据、上行控制和探测参考信号传输。自包含子帧类型的引入,可以实现统一的混合自动重传请求(英文:Hybrid Automatic Repeat reQuest,缩写:HARQ)定时,上下行快速HARQ反馈以及灵活的时分双工(英文:Time Division Duplexing,缩写:TDD)上下行配置等好处。
但由于S1子帧和S2子帧都包括保护时间间隔GP,一个无线帧中S1子帧和S2子帧的数量越多,GP的开销也会较大,因此,需要在S1子帧和S2子帧带来的增益和开销之间进行较好的折中。所以,在5G系统多套系统参数下,如何配置自包含子帧类型的GP是一个需要解决的问题。
