1. A method for uplink power control in OFDMA (Orthogonal Frequency Division Multiple Access) TDD (Time Division Duplex) system, the method comprising:
- calculating an RSSI (Received Signal Strength Indicator) average by using RSSIs measured from downlink signals; and
carrying out an uplink power control based on the RSSI average,wherein the RSSI average is calculated by using a weight that is determined according to a channel variation rate and a link symmetry.
