Abstract:
A method and Mobile Subscriber Station (MSS) are provided for transmitting Channel Quality Information (CQI) in a wireless communication system using an Orthogonal Frequency Division Multiple Access (OFDMA) scheme. A Carrier to Interference and Noise Ratio (CINR) of at least two bands are measured; each of the at least two bands including a plurality of adjacent subcarriers for a band Adaptive Modulation and Coding (AMC) operation. A Report Response (REP-RSP) message including first information related to the measured CINR is sent. Second information related to a differential CINR of the at least two bands is sent via a Channel Quality Information Channel (CQICH).
