Abstract:
1. A method of transmitting control signals in a wireless communication system, comprising: configuring, by a user equipment, an uplink control channel for a first control signal in a subframe, the subframe comprising two consecutive slots, each slot comprising a plurality of data orthogonal frequency division multiplexing (OFDM) symbols and a plurality of reference signal (RS) OFDM symbols, wherein configuring the uplink control channel comprises: generating, by the user equipment, a second modulation symbol by modulating a second control signal; multiplexing, by the user equipment, the second control signal on the uplink control channel by multiplying the second modulation symbol to one of the plurality of RS sequences; and transmitting, by the user equipment, the first control signal and the second control signal on the uplink control channel in the subframe.
