Patent ID: 8885595

Claim:
A method for transmitting control information through a Physical Uplink Control Channel (PUCCH) by a user equipment (UE) in a wireless communication system, the method comprising: obtaining a first modulation symbol and a second modulation symbol from the control information; spreading the first modulation symbol to a plurality of first contiguous Single Carrier-Frequency Division Multiple Access (SC-FDMA) symbols in a time domain; spreading the second modulation symbol to a plurality of second contiguous SC-FDMA symbols in the time domain; and transmitting the spread first modulation symbol and the spread second modulation symbol through the PUCCH, wherein the plurality of first contiguous SC-FDMA symbols and the plurality of second contiguous SC-FDMA symbols are located in a same slot, and wherein an index related to a first resource, from among a plurality of resources, occupied for the first or second modulation symbol is decided by a Control Channel Element (CCE) index used for Physical Downlink Control Channel (PDCCH) transmission, and an index related to a second resource, from among the plurality of resources, is decided by the index related to the first resource and an offset value.
