Abstract: A method of mapping a physical resource to a logical resource in a wireless communication system is described. The method includes dividing a physical frequency band into at least one frequency partition. Each frequency partition is divided into a localized region and a distributed region in a frequency domain. The method further includes mapping the at least one frequency partition into at least one logical resource unit. The localized region is directly mapped into the logical resource unit and the distributed region is mapped into the logical resource unit after rearranging subcarriers within the distributed region.

Abstract: A method is provided for transmitting an uplink (UL) control signal in a carrier aggregation (CA) system including a plurality of UL component carriers (CCs). A user equipment (UE) determines whether a simultaneous transmission of a physical UL control channel (PUCCH) and a physical UL shared channel (PUSCH) is configured. If the simultaneous transmission of the PUCCH and the PUSCH is not configured, the UE determines whether the PUSCH is scheduled in a primary CC (PCC) or in any secondary CCs (SCCs) of the CA system. If the PUSCH is not scheduled in the PCC, but is scheduled in the any SCCs, the UE selects one SCC from the any SCCs in which the PUSCH is scheduled according to a priority which is set by higher layer signaling. The UE piggybacks and transmits a UL control information (UCI) of the PCC on the PUSCH of the selected SCC.
