Method for transmitting uplink signal to minimize spurious emission and user equipment thereof

The one disclosed in the disclosure provides a method of transmitting uplink signals by limiting spurious emissions in a user equipment (UE). The method comprising the steps of: if the RF unit is set up to use the 3GPP standards-based E-UTRA band 1, and the protection provided between the UE, which is to protect only the same area (region) other area (inter-region) of the user equipment the method comprising in order even between, the maximum level of spurious emissions for protecting the UE of the E-UTRA bands 5 sets the RF unit so as not to exceed the -50dBm to apply and; When the RF unit is set up to use the standards-based 3GPP E-UTRA band 5, the protection provided between the UE which is only to protect the same area (region) in order to apply between different areas of the (inter-region), E- further comprising: a maximum-level of spurious radiation setting the RF unit so as not to exceed the -50dBm to protect the UTRA bands 1, 3, 7, 8, 38, 40 and any one of; Through the established RF unit may comprise transmitting an uplink signal.
