Abstract:
A process for cancelling inter-cell interference between neighboring cells in a synchronized OFDM communication system allowing communication between one User Equipment (UE) fitted with at least two antennas and one serving base station is provided. The process allows multi-antenna mobile receiver in a UE to receive downlink information from a base station that includes both information relating to proper communication with the base station and additional information that was received by the base station from a neighboring base station that provides interference data about another UE. The multi-antenna UE is adapted to use the downlink information in its receiver circuitry to cancel the interference from the other UE.
