In general, the first n (n is an integer equal to or greater than 1) number of symbols in a subframe can be configured as a downlink control zone and the last m (m is an integer equal to or greater than 1) number of symbols in a subframe can be configured as an uplink control zone in a TDD new frame structure. If an RACH sequence having long duration is applied to secure uplink coverage, the RACH sequence is unable to invade the downlink control zone or the uplink control zone or is unable to be overlapped with the zones. Hence, when the number of symbols included in one subframe corresponds to M, a length of the RACH sequence corresponds to {M?(n+m)}*1 symbols. Then, it is necessary to design an RACH within duration of the {M?(n+m)}*1 symbols including a CP and a GP for the RACH sequence. However, when a transmit power difference between a base station and a UE is considered, the duration of the {M?(n+m)}*1 symbols may have insufficient power compensation in increasing the coverage of the RACH sequence. Hence, the present invention proposes a method of performing puncturing on an uplink control zone to increase the coverage of the RACH sequence.

If it is assumed that an RACH sequence is transmitted on the center frequency of the N number of RBs (resource blocks) in an RACH subframe (in FIG. 10, third subframe from the left), an uplink control zone is punctured at the center frequency of the N number of RBs. For example, a base station does not schedule or allocate uplink control information at the center frequency of the N number of RBs.
