Abstract:
1. An Automatic Gain Control (AGC) apparatus in a relay apparatus supporting a full-duplex scheme, the relay apparatus configured for communication between a base station and a terminal, the AGC apparatus comprising: a controller configured to control: a Signal to Interference Ratio (SIR) estimation block configured to estimate an SIR based on an interference signal, which is estimated from a received signal and a signal transmitted from the relay apparatus, and an interference-cancelled signal determined by canceling the estimated interference signal from the received signal; a target Received Signal Strength Indicator (RSSI) determination block configured to determine a target RSSI optimized based on the estimated SIR and a maximum-rate Modulation and Coding Scheme (MCS) level for a particular resource region; and an AGC block configured to adjust a gain for the received signal based on the determined target RSSI.
