Patent ID: 8861467

Claim:
A method of transmitting uplink (UL) control information via a physical uplink control channel (PUCCH) by a user equipment in a wireless communication system, the method comprising: generating one or more blocks for each of 2 slots of a UL subframe by multiplying a modulated symbol for the UL control information and a cyclic-shifted sequence; block-wise spreading the blocks using an orthogonal code; and mapping one or more reference signals (RSs) and the spread blocks to the 2 slots of the UL subframe, respectively, and transmitting the RSs and the spread blocks to a base station, wherein a number of the blocks transmitted in a second slot among the 2 slots of the UL subframe has a same value for a case of configuring a transmission of sounding reference signal (SRS) in the UL subframe and a case of not configuring the transmission of the SRS.
