Patent ID: 8331343

Claim:
In a wireless communication system, a method of transmitting a signal from a user equipment to a base station, the method comprising: mapping, at the user equipment, the control signal to a cycle shifted sequence; performing a Discrete Fourier Transform (DFT) on user data; performing an Inverse Fast Fourier Transform (IFFT) on the mapped control signal, whereby generating a transformed control signal; performing the IFFT on the DFT-spread user data, whereby generating transformed user data; and transmitting at least one of the transformed control signal and the transformed user data in a subframe, the subframe comprising a control region and a data region in frequency domain, and a first slot and a second slot in time domain, wherein a first portion of the control signal is transmitted at a first frequency in the first slot of the control region and a second portion of the control signal is transmitted at a second frequency in the second slot of the control region, and wherein the user data is transmitted in the data region.
