Title: DATA SENDING METHOD AND APPARATUS
Abstract:
A data sending method and apparatus. The method is used in a multi-carrier communication system. The communication system comprises a first component carrier and a second component carrier, wherein the first component carrier is not only used for downlink transmission of a terminal, but is also used for uplink transmission of the terminal, and the second component carrier is a single downlink component carrier used for the downlink transmission of the terminal. The method comprises: a first base station determining an antenna weight value, on an antenna used by a second component carrier, of a first component carrier, wherein the first base station is a base station where the second component carrier is located; when the channel similarity between the first component carrier and the second component carrier satisfies a pre-set requirement, using the antenna weight value to weight downlink data, on the second component carrier, of the terminal; and sending the weighted downlink data to the terminal. In this way, a demodulation signal-to-noise ratio and throughput of a terminal in a multi-carrier scenario can be improved.
