Claim:
1. A wireless apparatus for transmitting an uplink signal in a wireless communication system, the wireless apparatus comprising: a Radio Frequency (RF) unit configured to receive a system information block (SIB) and transmit the uplink signal, wherein the SIB includes information specifying a predetermined channel bandwidth and information specifying, as an operating band, an evolved universal terrestrial radio access (E-UTRA) band 8; and a processor configured to configure the RF unit to use the predetermined channel bandwidth and use the E-UTRA band 8 based on the SIB, wherein, if the RF unit is configured to use the predetermined channel bandwidth and if the RF unit is configured to use the band 8 and is required to meet a predetermined maximum level of a spurious emission to protect another frequency range, the uplink signal is transmitted by using a specific number of resource blocks (RBs) calculated by subtracting a predetermined number of RBs from a total number of RBs corresponding to the predetermined channel bandwidth, wherein, if the predetermined channel bandwidth is 5 MHz, the predetermined number of RBs is 5, and wherein, if the predetermined channel bandwidth is 10 MHz, the predetermined number of RBs is 18.
