MOBILE TERMINAL AND METHOD FOR MEASURING CHANNEL QUALITY |
摘要 |
An Orthogonal Frequency Division Multiple Access (OFDMA)-based mobile terminal and a method for measuring reception channel quality for use in the OFDMA-based mobile terminal are provided. A mobile terminal includes a transceiver for exchanging frequency signal with a base station and a control unit for calculating a Carrier-to-Interference and Noise Ratio (CINR) of a data subcarrier with a second preamble of a downlink frame received through the transceiver. A mobile terminal and a method for measuring a channel quality for the mobile terminal enable calculating a CINR of data subcarriers using information contained in a second preamble that is provided in a downlink frame proposed, whereby the mobile terminal can provide a base station with more reliable channel quality information, resulting in avoiding degradation of communication quality and improvement of system throughput.
