Multiplexing control and data information from a user equipment in a physical data channel

A method for receiving hybrid automatic repeat request-acknowledgement (HARQ-ACK) bits by a base station in a communication system supporting carrier aggregation, the method comprising steps of:

• transmitting a configuration of a plurality of cells by higher layer signaling;
• and
• receiving, from a user equipment (UE), signals for HARQ-ACK bits on one physical uplink shared channel (PUSCH) of multiple PUSCHs based on a number of coded symbols, in case that the multiple PUSCHs exist in a slot,
• wherein the number of coded symbols is identified based on a number of the HARQ-ACK bits and one HARQ-ACK offset, wherein the one HARQ-ACK offset corresponds to the number of the HARQ-ACK bits,
• wherein the HARQ-ACK bits for the plurality of cells are obtained based on an order of a cell index for each of the plurality of cells and a number of one or more transport blocks for each of the plurality of cells,
• wherein the number of one of more transport blocks for each of the plurality of cells is identified based on the configuration of the plurality of cells,
• wherein in case that a cell is configured with up to 2 transport blocks, 2 HARQ-ACK bits for the cell are included in the number of the HARQ-ACK bits, and in case that a cell is configured with up to 1 transport block, 1 HARQ-ACK bit for the cell is included in the number of the HARQ-ACK bits, and
• wherein in case that the number of the HARQ-ACK bits is 3, the HARQ-ACK bits are encoded by a (32, O) block code, where the O is the number of the HARQ-ACK bits.
