Abstract
A method for limiting a spurious emission, and a user equipment (UE) thereof are discussed. The method according to one embodiment includes configuring a radio frequency (RF) unit of the UE to use a band 1; if the RF unit is configured to use the band 1, controlling the RF unit of the UK to limit a maximum level of spurious emission to −50 dBm for protecting another UE using a band 5; and transmitting an uplink signal through the configured RF unit. The band 1 includes an uplink operating band of 1920-1980 MHz and a downlink operating band of 2110-2170 MHz. The band 5 includes an uplink operating band of 824-849 MHz and a downlink operating band of 869-894 MHz.
