WebTDD (Time Division Duplexing) is used in TD-SCDMA to separate the uplink and downlink. The frame length (or the TDD interval) of TD-SCDMA is 5 ms and the whole frame is divided into downlink and uplink by the two switching points. Both the uplink and downlink periods are divided into timeslots. The total number of timeslots is 7. Web10 apr 2024 · 2G移动通信系统采用时分多址接入（TDMA）或者码分多址接入（CDMA）技术，并采用数字调制技术。 ...
