摘要

Apparatus and method for communication are provided. The apparatus means for communicating with a number of user equipment using Orthogonal Frequency-Division Multiple Access connections on given data regions; means for selecting one or more data regions for each connection; and means for selecting the transmission power to be used on each connection, wherein the selection of data regions and powers is performed by minimising the total transmission power used on all connections while fulfilling the performance criteria of each connection.
