Time Division Duplex (TDD)

By employing TDD technology, TD-SCDMA transmits the uplink and downlink signals via the different timeslots of the same frequency band.


Advantages of TDD technology
Flexible allocation of frequency spectrum: easy to utilize unpaired frequency bands; pairs of frequency bands with specific duplex separation are not necessary;
Supporting asymmetrical services effectively: meet the users’ needs on services by flexibly adjusting uplink and downlink timeslot commutation point; high spectrum efficiency;
Easy to apply advanced technologies: uplink and downlink work at the same frequency point and the channel environment is reciprocal where advanced technologies such as SA could be easily applied;
Saving costs: there is no need for cumbersome radio frequency duplexer; compact base station can help reduce costs.
TDD technology’s impacts on network construction:
Especially suitable for asymmetrical data service and quickly meeting the demand for the dynamic development of services; Advance the utilization of network resources and save operating expenses.
