METHOD FOR SELECTING ANTENNAS IN OFDMA WIRELESS NETWORK |
摘要 |
PROBLEM TO BE SOLVED: To select antennas in an OFDMA network. SOLUTION: A channel state of a downlink is measured using a downlink subframe received in a mobile station from a base station. A channel state of an uplink is measured using an uplink subframe received in the base station from the mobile station. Next, the method compares the channel states to determine whether the downlink and the uplink are reciprocal or not. The mobile station can perform receive antenna selection based on the quality of the downlink channel state. The mobile station can also perform transmit antenna selection when instructed by the base station. COPYRIGHT: (C)2009,JPO&INPIT |
