A method for operating a user equipment (UE) includes determining a maximum number of resource elements (REs) of a physical uplink shared channel (PUSCH) for multiplexing first hybrid automatic repeat request acknowledgement (HARQ-ACK) information. The maximum number of REs is determined by scaling, with a factor, a total number of REs available for multiplexing the first HARQ-ACK information in the PUSCH. The PUSCH has a first priority value. The factor has a first value when the first HARQ-ACK information has the first priority value. The factor has a second value when the first HARQ-ACK information has a second priority value. The method further includes multiplexing the first HARQ-ACK information in the PUSCH over a number of REs that is smaller than or equal to the maximum number of REs and transmitting the PUSCH.
