SYSTEM AND METHOD OF BAND SUBCHANNEL CONTROL WITH ADAPTIVE MODULATION AND CODING (AMC) IN COMMUNICATION SYSTEM OF MULTIPLE ACCESS WITH ORTHOGONAL-FREQUENCY DIVISION Russian patent published in 2009 - IPC H04B7/26 H04W72/08 

FIELD: information technologies.

SUBSTANCE: method for assignment of band channel with adaptive modulation and coding (AMC) to subscriber stations (SS) is realised in wireless communication system, which separates full range of frequencies into multiple subcarrier bands, every of which represents set from previously specified quantity of subranges, every of which represents set of previously specified quantity of adjacent subcarriers. Method comprises the following stages: necessity in use of band channel with AMC is detected; quality of reception is measured in frequency bands; list of frequency bands with high quality of reception is formed; request is sent for assignment of band channel with AMC as well as foresaid list to base station (BS); response is received to mentioned request from BS; in compliance with response, changeover is done in SS in condition of use of band channel with AMC.

EFFECT: creation of flexible system that provides possibility for subscriber stations with proper condition of channel to realise high-speed communication with high throughput.
