TD-SCDMA的基本特征是采用双工模式。与WCDMA和CDMA2000所使用的对称下行(DL)和上行(UL)频谱有所不同,TD-SCDMA能够在同一频段下实现下行和上行传输,这得益于的TD-SCDMA独特的架构,每个无线帧长10毫秒,被分为2个分别长5毫秒的子帧。每个子帧又包含7个常规时隙(TS)及3个
The basic feature of TD-SCDMA is the use of duplex mode. Unlike the symmetric downlink (DL) and uplink (UL) spectrum used by WCDMA and CDMA2000, TD-SCDMA is capable of downlink and uplink transmission in the same frequency band thanks to the unique architecture of TD-SCDMA, each The wireless frame length is 10 milliseconds and is divided into two subframes each having a length of 5 milliseconds. Each subframe in turn contains seven regular time slots (TS) and three
