MULTIPLEXING LARGE PAYLOADS OF CONTROL INFORMATION FROM USER EQUIPMENTS

摘要

An apparatus and method for transmitting Uplink Control Information (UCI) over a Physical Uplink Control CHannel (PUCCH) in a communication system. The method includes acquiring information for configuration of a first PUCCH format and a second PUCCH format; generating UCI to be transmitted; selecting one of the first PUCCH format and the second PUCCH format for transmitting the UCI; encoding the generated UCI; performing an Inverse Fourier Transform (IFT) operation on the encoded UCI; and transmitting the IFT performed UCI using the selected PUCCH format. The second PUCCH format is selected, if the transmitting of the UCI is related to multiple downlink carriers.
