Abstract

Methods and apparatus are described for transmitting and receiving HARQ-ACK information in a Physical Uplink Shared CHannel (PUSCH). A method of receiving includes configuring a plurality of cells for a user equipment (UE), where each of the plurality of cells is associated with one transmission mode; receiving, from the UE, via a physical uplink shared channel (PUSCH), encoded concatenated HARQ-ACK bits for the plurality of cells; and decoding encoded concatenated HARQ-ACK bits. HARQ-ACK bits for the plurality of cells are concatenated based on an order of a cell index for each of the plurality of cells, and the concatenated HARQ-ACK bits include 2 HARQ-ACK bits for a cell associated with a transmission mode supporting up to 2 transport blocks and 1 HARQ-ACK bit for a cell associated with a transmission mode supporting up to 1 transport block.
