Abstract
Methods, apparatus and computer program products are provided for rebalancing the sizes of downlink (DL) association sets for component carriers having different time division duplex subframe configurations. A method is provided that includes determining DL subframes that are included in a DL association set for each of a plurality of component carriers. In an instance in which the number of acknowledgement (ACK)/negative acknowledgement (NACK) bits corresponding to the DL subframes included in the DL association sets for respective component carriers differ by at least a predetermined amount, the method modifies the number of ACK/NACK bits corresponding to the DL subframes that are included in the DL association sets for each of the respective component carriers. The method may also cause transmission of the ACK/NACK bits in accordance with the DL association sets, as modified, via the respective component carriers. Corresponding apparatus and computer program products are also provided.
