TD-SCDMA Technology

TD-SCDMA (time division - synchronous code division multiple access) is a cellular technology based on the combination of a TDMA (time division multiple access) component and a CDMA (code division multiple access) component. Additionally, unique synchronization mechanisms are foreseen for optimizing the time division duplex (TDD) mode of operation. The uplink and downlink are separated in time, i.e. specific timeslots within one time frame are assigned separately to uplink and downlink transmission.
