Abstract:
1. A method for transmitting control signals at a mobile station (MS) in a wireless communication system, the method comprising: transmitting pilot signals generated by using a code sequence via two or more resource blocks in a frequency domain at first single carrier frequency division multiplexing access (SC-FDMA) symbols located in a middle of each of consecutive time domain units; and transmitting the control signals via the two or more resource blocks in the frequency domain at second SC-FDMA symbols other than the first SC-FDMA symbols within the consecutive time domain units, wherein the two or more resource blocks are dedicated to transmission of the control signals without transmission of data traffic, wherein the two or more resource blocks include a first resource block and a last resource block of a transmission bandwidth, wherein the control signals are transmitted via the last resource block at one of the consecutive time domain units, if the control signals were transmitted via the first resource block at the other of the consecutive time domain units, and wherein the control signals are multiplied by the code sequence used for generating the pilot signals along with subcarriers at the second SC-FDMA symbols within each of the two or more resource blocks.
