METHOD FOR LINK ADAPTATION IN WIDEBAND WIRELESS MOBILE COMUNICATION SYSTEMS, SYSTEM AND APPARATUS THEREOF |
摘要 |
<p>A method for link adaptation in wide-band wireless mobile communication systems is disclosed. By analyzing state information of the channel, the channel variety factor is calculated. Then a decision is taken to determine whether the state of the current channel varies dramatically based on the channel-varying factor. If so, signals are transmitted by using BR-OFDMA (Block Repeat- Orthogonal Frequency Division Multiple Access) mode; otherwise, signals are transmitted by using OFDMA (Orthogonal Frequency Division Multiple Access) mode. The corresponding wide-band wireless mobile communication system and apparatus are also disclosed. The method, system and apparatus can enhance the spectrum efficiency under high-speed mobile circumstance.</p> |
