Abstract: A method, a system and an apparatus for ACK/NACK resource reservation are provided. The method includes: a base station configures and notifies usable uplink control channel resources to a user terminal using transmit diversity for ACK/NACK transmission, said base station receives the ACK/NACK transmitted by the said user terminal on the configured channel resources. The reservation of channel resource that is used in ACK/NACK feedback is realized, and the method for resource reservation supports transmit diversity, and improves the reliability of uplink control channel transmission, and the method is simple and easy to implement.

Abstract: A distributed smart antenna system including an antenna array having N antenna elements, N radio frequency tranceivers, and feeder cables connecting both. N antenna elements and N radio frequency transceivers are grouped according to cell coverage range and traffic volume. Antenna element groups are then distributed at different places of coverage within the range of the same wireless communication system base station, including different buildings or different floors of same building; however, the same baseband digital signal processor is used. Each antenna element group can have one to M antenna elements. The system enables improved cell coverage, increased system capacity, and decreased system cost.
