Method and appratus for controlling signal transmission

摘要

A method and apparatus for controlling signal transmission is provided. The method includes determining whether a signal to noise ratio (SNR) between a first base station and a signal receiving node is less than a threshold, and controlling the first base station and a second base station to cooperatively transmit a signal to the signal receiving node in response to the SNR being less than the threshold. Further, the second base station is located in an adjacent cell to a cell containing the first base station.

1. A method, executed by a controller of a cooperative communication system, for controlling signal transmission of the cooperative communication system, the method comprising:
determining whether a signal to noise ratio (SNR) between a first base station and a signal receiving node is less than a threshold; transmitting channel information about the signal receiving node to a second base station in response to the SNR being less than the threshold; controlling the first base station and the second base station to cooperatively transmit a signal to the signal receiving node in response to the SNR being less than the threshold, where the second base station is included in an adjacent cell to a cell including the first base station; and calculating a signal to interference plus noise ratio (SINR) of the signal receiving node, based on a reception signal received by the signal receiving node, and calculating a data rate using the SINR.
