METHOD FOR SENDING INFORMATION FROM BASE STATION TO RELAY STATION

摘要

The present invention provides a method for sending information from a base station to a relay station, comprising taking information from the base station to the relay station and information from the base station to a single-hop terminal as the additional message and the basic message respectively, superposing the additional message and the basic message together for modulating by using a hierarchical modulation mode; and sending the hierarchically modulated information by the base station to the relay station. By using the present invention, signaling information and/or delay sensitive operation data can be sent from the base station to the relay station in a timely manner, thus to improve system performance, and furthermore, by using the present invention it is possible not to employ additional system resources, so as to improve the utilization rate of system resources, namely, to improve the frequency spectrum efficiency.
