Uplink signal transmission method and user equipment capable of protecting neighboring band from mobile satellite service band

A method for transmitting an uplink signal by a user equipment, comprising:

• receiving a network signal for limiting transmission power,
• wherein the network signal is received, when the uplink signal is transmitted through an uplink carrier within an uplink band being adjacent to both an evolved-universal terrestrial radio access (E-UTRA) band 33 and a E-UTRA band 39 such that the uplink signal is likely to cause interference to any one of the E-UTRA\ band 33 and E-UTRA band 39;
• determining a transmission power by adopting additional maximum power reduction (A-MPR) based on the received network signal;
• determining a guard band based on the received network signal;
• and
• transmitting the uplink signal through the uplink carrier in accordance with the determined transmission power and guard band,
• wherein when the uplink band corresponds to E-UTRA band 65, a value being indicated by the network signal is different from a value being indicated by a network signal for E-UTRA band 1 that is positioned to be adjacent to the MSS band.

A user equipment for transmitting an uplink signal, comprising:

• a radio frequency (RF) unit configured to transmit and receive radio signals through a band overlapping with part of a mobile satellite service (MSS) band;
• and
• a processor configured to control the RF unit,
• wherein the processor controls the RF unit thereby:
• receiving a network signal for limiting transmission power,
• wherein the network signal is received when the uplink signal is transmitted through an uplink carrier within an uplink band overlapping with part of a mobile satellite service (MSS) band such that the uplink signal is likely to cause interference to a personal handyphone system (PHS) band,
• determining a transmission power by adopting additional maximum power reduction (A-MPR) based on the received network signal, and
• transmitting the uplink signal through the uplink carrier in accordance with the determined transmission power,
• wherein when the uplink band corresponds to evolved-universal terrestrial radio access (E-UTRA) band 65, a value being indicated by the network signal is different from a value being indicated by a network signal for the E-UTRA band 1 that is positioned to be adjacent to the MSS band.
