Patent ID: 7756521

Claim:
A method for allocating subcarrier frequencies to a user terminal in a wireless telecommunications system using multi-carrier modulation 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, described by the following steps: upon terminal channel transfer function estimation over a certain period of time, the terminals report to the network, over their feedback channel, if their channel transfer function is predictable or not and if they want to participate in a frequency-selective subcarrier allocation method or not; depending on the information about the number of terminals participating in the frequency-selective allocation procedure, their respective traffic demands and their channel transfer function characteristics, the network partitions the subcarrier frequency set available in at least two logical blocks or frequency subsets; the participating terminals report back to the network information about their measured channel transfer function and interference noise estimate through the feedback channel; and the network, according to this information, allocates the subcarrier frequencies of at least one first frequency first subset to the participating terminals following a frequency-selective allocation scheme by assigning to said terminals subcarriers that are useful for transmission according to their feedback information about the channel transfer function and allocates the subcarrier frequencies of at least one second frequency subset to the rest of the terminals according to a frequency interleaving scheme.
