Description

一种被用于低延迟通信的用户设备、基站中的方法和装置 技术领域
本申请涉及无线通信系统中的无线信号的传输方案，特别是涉及支持低延迟通信的用户设备及基站中的方法和装置。
背景技术
现有的LTE(Long-term Evolution，长期演进)及LTE-A(Long Term Evolution Advanced，增强的长期演进)系统中，TTI(Transmission Time Interval，传输时间间隔)或者子帧(Subframe)或者PRB(Physical Resource Block，物理资源块)对(Pair)在时间上对应一个ms(milli-second，毫秒)。一个LTE子帧包括两个时隙(Time Slot)，分别是第一时隙和第二时隙，且所述第一时隙和所述第二时隙分别占用一个LTE子帧的前半个毫秒和后半个毫秒。
3GPP(3rd Generation Partner Project，第三代合作伙伴项目)Release 14中的Latency Reduction(LR，延迟降低)课题中，一个重要的应用目的就是低延迟通信。针对降低延迟的需求，传统的LTE帧结构需要被重新设计，与之相对应的，新的调度方式也需要被考虑。
发明内容
Release 14降低延迟相关的Study Item(研究课题)中，一个需要被研究的方向就是下行调度和上行调度的传输方式和调度颗粒度(Granularity)的设计。LTE系统中，上下行调度在物理层的调度颗粒度是一个PRB(Physical Resource Block，物理资源块对)对，即最小调度单位是一个PRB对，且针对不同的系统带宽定义了不同的RBG(Resource Block Size)大小，以进一步应用于不同的资源分配方式(Resource Allocation Type)。目前在Release 14的LR课题中，基站和UE(User Equipment，用户设备)可以支持不同的sTTI(Short Transmission Time Interval，缩短的传输时间间隔)。随着而来的问题就是，针对不同的sTTI，系统是否需要设计新的多种不同的TBS(Transmission Block Size， 传输块尺寸)来支持不同的sTTI所对应的不同的持续时间。
一种直观的解决方法，就是针对不同的sTTI的持续时间，结合现有的TBS的大小，分别引入新的TBS，并沿用现在DCI(Downlink Control Information，下行控制信息)中关于RA(Resource Allocation，资源分配)的信息域(Information Field)。然而这样的设计方式，明显会给UE带来较大的实现复杂度，且标准化工作繁重。同时，若考虑到目前两级(Two-level)DCI的设计，此种方法会增加控制信令的开销和盲检测的复杂度。
针对上述问题，本申请提供了解决方案。需要说明的是，在不冲突的情况下，本申请的实施例和实施例中的特征可以任意相互组合。例如，本申请的UE中的实施例和实施例中的特征可以应用到基站中，反之亦然。
