Abstract:
1. A method for a user equipment (UE) to transmit, to a base station, acknowledgement information, the method comprising the steps of: receiving, from the base station, at least one scheduling assignment corresponding to at least one carrier, wherein N carriers are configured by the base station through radio resource control signaling, each of the N carriers is associated with a transmission mode (TM), and the TM relates to a maximum number of transport blocks (TBs) transmitted in a physical downlink shared channel (PDSCH); generating, by the UE, N+M acknowledgement bits in response to reception of at least one TB in the at least one carrier among the N carriers; ordering, by the UE, the N+M acknowledgement bits in a codeword based on indices of the N carriers, encoding the codeword, wherein a method of the encoding is determined based on a number of the generated N+M acknowledgement bits; and transmitting the codeword in a physical uplink shared channel (PUSCH), wherein M is a number of carriers supporting 2 TBs on the PDSCH, and wherein N−M is a number of second carriers supporting one TB on the PDSCH.
