Title:
TRANSMISSION METHOD FOR DOWNLINK CONTROL SIGNAL IN TD-SCDMA EVOLUTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2008/101401
Kind Code:
A1
Abstract:
A transmission method for downlink control signal in a Time Division-Synchronous Division Multiple Access evolution system comprises the downlink control signal only being transmitted once in each of half of a wireless frame based on the system structure character, which could be transmitted in any downlink slot and has kinds of transmission modes. The UE determines the slot position of the downlink control signal based on the system configuration, and receives the downlink control signal in the corresponding slot position, and completes the own service data transmission control based on the received downlink control signal. Using the solution, the control signal overhead and common reference symbol overhead could be saved, while it's easy to use the close-loop multiple-antenna transmission technology, such as the beam-forming.
