Abstract

Methods and apparatus are described for multiplexing a hybrid automatic repeat request-acknowledgement (HARQ-ACK) bit in a physical uplink shared channel (PUSCH) by a user equipment (UE) in a communication system. A method includes acquiring configuration information on at least one offset for HARQ-ACK; determining a number of coded symbols for at least one HARQ-ACK bit based on one offset from among the at least one offset, wherein the one offset is identified according to a number of the at least one HARQ-ACK bit; obtaining the at least one HARQ-ACK bit coded based on the number of coded symbols; and multiplexing the coded at least one HARQ-ACK bit in a PUSCH.
