Abstract:
1. A method for communications device operations, the method comprising: determining a hybrid automatic repeat request (HARQ) response for each component carrier (CC) in a first set of CCs configured by higher layer signaling, thereby producing a set of HARQ responses; generating an information vector from the set of HARQ responses, wherein the information vector comprises a sub-vector composed of one or more bits selected from the information vector and the sub-vector is assigned a fixed vector value if no transmission is detected over at least one CC in a second set of CCs when the second set of CCs is not empty, the second set of CCs being a subset of the first set of CCs, the fixed vector value being independent of HARQ responses for CCs not in the second set of CCs and wherein the generating the information vector is by mapping a set {ACK, NACK} to a set {(ACK, ACK), (ACK, NACK), (NACK, ACK), (NACK, NACK)} in case of a single transport block transmission for a CC; encoding the information vector; and transmitting the encoded information vector.
