Methods and apparatuses for indicating an interference distribution in frame between base stations are provided. The method comprises: in response to a mismatch between a first frame allocation used by a first base station and a second frame allocation used by a second base station, transmitting, from the first base station to the second base station, a message for indicating an interference distribution in frame, A new information element, i.e., UL ABS (uplink Almost Blank Subframe) is introduced to indicate the uplink ABS information of the interfering base station. A modified DL ABS with a flag is used to indicate the downlink ABS information of the interfering base station, wherein the flag is to indicate that the DL ABS is used to protect UL transmission in the recipient base station. |
