    Abstract: The present invention provides for applying a cyclic redundancy check (CRC) to a data signal. The present invention includes attaching a first CRC to a first data signal block having a first length, segmenting the first data signal block attached with the first CRC into a plurality of second data signal blocks having a length shorter than the first length, respectively generating a second CRC for each second data signal block, and attaching the generated second CRC to the respective second data signal block. Moreover, the first CRC and second CRC may be generated from respectively different CRC generating polynomial equations.

    Abstract: A method of transmitting a sounding reference signal (SRS) includes receiving SRS operation information including a sounding indicator, the sounding indicator indicating whether SRS transmission takes place at a subframe; generating the SRS according to the SRS operation information, and if the sounding indicator indicates occurrence of SRS transmission, transmitting the SRS at the subframe. Multiplexing can be achieved without collision between data and a sounding reference signal and single carrier characteristics required in uplink transmission can be preserved.
