Abstract
This invention describes method and apparatus for automatic gain control (AGC) for a TD-LTE system, taking into consideration the TD-LTE frame structure. In one embodiment, an AGC method comprises: adjusting RF gain for subframe j (where 0<=j<=9) in a radio frame according to an average peak signal power of subframe j in previous radio frames when a terminal is lack of information in downlink timing and in uplink/downlink configuration; computing a first average signal power in one or more downlink subframes as received from at least one base station when the terminal has information in downlink timing but is lack of information in uplink/downlink configuration; and computing a second average signal power in one or more downlink subframes as received from at least one base station when the terminal has information in downlink timing and in uplink/downlink configuration.
