There are two types of frame structure in theLTEstandard, Type 1 and Type 2. Type 1 uses Frequency Division Duplexing (uplink and downlink separated by frequency), andTDDuses Time Division Duplexing(uplink and downlink separated in time). This overview is not an exhaustive description of the ...

FDD: Frame Structure Type 1: 对于FDD,上下行用不同的频带,一般上下行的带宽是一致的,因此在FDD中,每个无线帧的10个子帧都可以传输下行,也都可以传输上行,上下行在不同的频域中分别进行。在半双工的FDD模式下,UE不能在同一个子帧里既发送数据又接收数据,而在全双工的FDD模式下,UE在同一个子帧里可以同时发送...

In this section, we first briefly recall the framework of LTE uplink technology. Then, the open-loop FPC scheme of LTE Release 8 is outlined, which is followed by the discussion on the constraints of resource allocation. 2.1. LTE uplink technology and frame structure LTE uplink has adopted...
The frame structure below (Figure 1) is applicable to TDD. Each radio frame of length Tf = 307200*Ts = 10 ms consists of two half-frames of length Tf = 153600*Ts = 5 ms each. Each half-frame consists of five subframes of length 307200*Ts = 1 ms. The supported uplink-downlink ...
