Abstract

A method for allocating subcarrier frequencies to a user terminal in a wireless system using multi-carrier modulation such as OFDM in which a network is adapted to communicate with a plurality of user terminals for data transmission, signaling control and link adaptation via an air interface downlink channel and feedback channel, and where a number of terminals estimate their own specific channel transfer function, wherein upon terminal channel transfer function estimation over a certain period of time, a set of terminals report to the network, over their feedback channel, information about their measured channel transfer function and interference noise estimate and the network, according to this information, allocates the subcarrier frequencies of at least one first frequency subset to the set of terminals which sent said information following a frequency-selective allocation scheme and allocates the subcarrier frequencies of at least one second frequency subset to the rest of the terminals according to a frequency interleaving scheme.
