FIELD: communications engineering. ^ SUBSTANCE: proposed band selection method for mobile orthogonal frequency division multiple access communication system includes following steps to classify procedures of band selection between sending end and receiving ends with respect to original band selection process, passband width selection process, and periodic band selection process: determination of source band selection code (SC)number for source band selection process; SC number to request passband width for passband width request selection process and periodic SC number for periodic band selection process; determination of periodic SC deferment value in compliance with periodic SC number, and transmission of source SCs, passband width request SC, periodic SCs, and periodic SC deferment values on receiving ends. ^ EFFECT: minimized time for band selection access. ^ 22 cl, 3 dwg, 4 tbl |
