Claim Text:
1. A method of communication, performed by a first base station in communication with User Equipment (UE) in a wireless communication system operating in Time Division Duplex (TDD) mode, in the presence of interference from a second base station that employs Almost Blank Subframes (ABS) in a predetermined pattern, comprising: monitoring a Sequence Frame Number (SFN) associated with each TDD time slot; as a current SFN approaches the end of a predetermined SFN period length, recognizing that the predetermined ABS pattern will change in a subsequent SFN period; and in response to recognizing the change in the ABS pattern, commanding the UE to alter a transmission to the first base station in an allocated TDD time slot to improve the probability of accurate reception at the first base station, wherein the transmission to be altered to improve the probability of reception is an uplink retransmission transmitted in response to the receipt by the UE from the first base station of a negative acknowledgement and wherein commanding the UE to alter a transmission to the first base station to improve the probability of accurate reception comprises commanding the UE to increase the transmit power for the transmission.
