A method includes receiving information defining a PUCCH pattern to be used by a first UE to transmit a PUCCH to a first base station (BS). In response to PUCCH regions overlapping downlink regions in a downlink bandwidth to be used by the second BS for a downlink transmission to a second UE, performing the downlink transmission from the second BS to the second UE. The second BS performs downlink transmission avoidance by not scheduling downlink transmission in the downlink regions that overlap with the PUCCH regions or muting the downlink transmission or reconfiguring a subframe for uplink transmission. Another method includes transmitting, from a first BS, information defining the PUCCH pattern. Based on a response from a second BS, interference mitigation technique(s) are or are not performed by the first BS for an uplink transmission to be performed by the UE to transmit the PUCCH to the first BS. |
