Claim 4:
5. A method performed by a base station in a communication system, the method comprising:
receiving, from a user equipment (UE), at least one of periodic channel state information (CSI) and a hybrid automatic repeat request acknowledgement (HARQ-ACK) in a subframe,
wherein, based on the UE being configured with more than one serving cell and simultaneous PUSCH and PUCCH transmission, the periodic CSI is received on a physical uplink shared channel (PUSCH) of a secondary cell (SCell) with a smallest SCell index other than a licensed-assisted access (LAA) SCell and the HARQ-ACK is received on a physical uplink control channel (PUCCH) in case that the PUSCH is received on at least one SCell, and
wherein the periodic CSI and the HARQ-ACK is received on the PUCCH in case that the PUSCH is only on the LAA SCell and a simultaneous transmission of the periodic CSI and the HARQ-ACK is configured.
