Method and system for determining initial transmission power

A user equipment device (UE) comprising:

• a wireless communication interface configured to engage in communication on a plurality of carrier frequencies including a first carrier frequency and a second carrier frequency;
• and
• a control unit configured to (i) determine a transmit power used by the UE for a transmission from the UE to a first base station on the first carrier frequency, (ii) use the determined transmit power as a baseline initial transmit power for the UE to use for an initial transmission from the UE to a second, different base station, (iii) make a comparison of a first geographic location of the first base station with a second geographic location of the second base station, and (iv) based on the second carrier frequency being different than the first carrier frequency, and further based on the comparison of the first geographic location of the first base station with the second geographic location of the second base station, adjust the baseline initial transmit power to establish an adjusted initial transmit power,
• wherein the wireless communication interface is configured to engage in communication with the second base station by providing the initial transmission to the second base station at the adjusted initial transmit power.

A method comprising:

• determining by a user equipment device (UE) a transmit power used by the UE for a transmission from the UE to a first base station on a first carrier frequency;
• using by the UE the determined transmit power as a baseline initial transmit power for the UE to use for an initial transmission from the UE to a second, different base station;
• making by the UE a comparison of a first geographic location of the first base station with a second geographic location of the second base station;
• based on (i) the initial transmission being on a second carrier frequency different than the first carrier frequency and (ii) the comparison of the first geographic location of the first base station with the second geographic location of the second base station, adjusting by the UE the baseline initial transmit power to establish an adjusted initial transmit power;
• and
• engaging by the UE in the initial transmission to the second base station using the adjusted initial transmit power.
