Retransmissions in a Communication System Using Almost Blank Subframes

摘要

A method and apparatus for controlling retransmissions of subframes is disclosed. In the method the type of a received subframe is determined. Identification of the subframe for retransmission purposes is then controlled based on the determined type of the subframe. A node receiving a request for retransmission of the subframe provided with an identification based on the type of the subframe determines based on the identification for retransmission purposes the subframe for which retransmission is requested.
