Claim:
1. A method of receiving a frame comprising: receiving the frame from the terminal, the frame comprising a control signal and a reference signal; transforming the control signal to generate a transformed control signal; transforming the reference signal to generate a transformed reference signal; multiplying the transformed control signal with a first sequence to generate a second sequence; determining uplink control information based on the second sequence; and multiplying the transformed reference signal with a third sequence to generate a fourth sequence; wherein the first sequence is one of a first set of sequences which are orthogonal to each other in time domain, wherein the third sequence is one of a second set of sequences which are orthogonal to each other in time domain, wherein the first set of sequences consists of three (3) sequences, the three sequences comprising at least two sequences of (1, 1, 1, 1) and (1, −1, 1, −1).
