摘要:
The present invention relates to a method for sending channel quality information in a multi-carrier radio communication system comprising at least one mobile terminal and at least one base station, said channel quality information being sent on a signaling channel by said mobile terminal to said base station.According to the present invention, the method comprises the steps of: performing channel quality measurements on a plurality of frequency sub-carriers; generating and sending a first report over said signaling channel, said first report comprising a first channel quality information depending on said channel quality measurements on at least one sub-carrier, said at least one sub-carrier building an herein called first group of sub-carriers; determining a number of additional reports depending on the mobility grade of said mobile terminal; if said number of additional reports is not reached, generating and sending an additional report over said signaling channel comprising an additional channel quality information depending on channel quality measurements on at least one sub-carrier, said at least one sub-carrier building an herein called second group of sub-carriers, said second group of sub-carriers being different of said first group of sub-carriers.

The invention concerns a method for performing frequency selective control channel scheduling in networks using an OFDM spectrum, whereby a base station (BS1-BS8) broadcasts on at least one predefined subcarrier which is known to all mobile terminals (T1-T4) a signaling information common to all mobile terminals (T1-T4) indicating the position of at least one subcarrier of at least one frequency selective shared control channel and at least one identification of at least one addressed mobile terminal, the base station (BS1-BS8) sends signaling information for said at least one addressed mobile terminal at the indicated position of said at least one subcarrier of said at least one frequency selective shared control channel, and at least one mobile terminal (T1-T4) measures at least one subcarrier of said at least one frequency selective shared control channel for channel quality estimation, a base station (BS1-BS8), a mobile terminal (T1-T4) and a network (CN) therefor.

The present invention relates to a method for gaining channel quality information at a base station of a multi-carrier radio communication system having a plurality of orthogonal frequency sub-carriers. According to the present invention, the method comprises the steps of: measuring a Channel Frequency Response at a user terminal of said multi-carrier radio communication channel; extracting samples of said Channel Frequency Response represented in the frequency domain at a predefined oversampling factor; sending said samples on a signaling channel from said user terminal to said base station; performing a windowing operation on the received samples in the time domain; determining a channel quality information for each of said sub-carriers on a representation in the frequency domain of said received samples after windowing operation.
