Method to control the effects of out-of-cell interference in a wireless cellular system using backhaul transmission of decoded data and formats

A base station of a wireless communication system comprising a plurality of other base stations, wherein the base station and the plurality of other base stations are adapted to communicate with each other and with one or more mobile terminals, the base station comprises:

• a receiver configured to:
• receive a signal from a mobile terminal;
• decode successfully the received signal into decoded data;
• and
• transmit decoded data and a transmission format of the received signal from which the successfully decoded data was obtained to at least one of the other base stations, the transmission format including a number of retransmissions that were required for the base station to successfully decode the data, the decoded data and the transmission format being usable by the at least one of the other base stations to remove, from other signals received at the at least one other base station, interference attributable to transmission of the received signal.

A base station for use in a wireless communication system comprising at least one other base station, wherein the base stations are capable of communicating with each other, the base station comprises:

• a receiver configured to:
• receive, from the at least one other base station, data that was successfully decoded by the at least one other base station from a received signal received by the at least one other base station from a mobile terminal, along with a transmission format of the received signal, said transmission format including a number of retransmissions that were required for the at least one other base station to successfully decode the data;
• and
• remove, from other signals received at the base station, interference attributable to transmission of the received signal using the successfully decoded data and the transmission format.

A base station of a wireless communication system comprising a plurality of other base stations, wherein the base station and the plurality of other base stations are adapted to communicate with each other and with one or more mobile terminals, the base station comprises:

• a receiver that receives signals from a mobile terminal;
• a decoder that successfully decodes the received signal into decoded data;
• and
• a transmitter which transmits successfully decoded data and a transmission format of the received signal from which the successfully decoded data was obtained to at least one of the other base stations, the transmission format including a number of retransmissions that were required for the base station to successfully decode the data, the decoded data and the transmission format being usable by the at least one of the other base stations to remove, from other signals received at the at least one of the other base stations, interference attributable to transmission of the received signals.
