METHOD AND APPARATUS FOR CONTROLLING UPLINK POWER OF USER EQUIPMENT IN CARRIER AGGREGATION SCENARIO

摘要

The present invention provides a method and an apparatus for controlling uplink power of a user equipment, where the method includes: separately acquiring first maximum transmit power of the user equipment corresponding to a first subframe and second maximum transmit power of the user equipment corresponding to a second subframe; and when the first maximum transmit power and the second maximum transmit power are different, using a minimum value of the first maximum transmit power and the second maximum transmit power as first configured maximum transmit power, and performing power control over transmit power of multiple carriers in an overlap region according to the first configured maximum transmit power, so that total transmit power of the multiple carriers in the overlap region after the power control is lower than or equal to the minimum value of the first maximum transmit power and the second maximum transmit power.

1. A method for controlling uplink power of a user equipment in a carrier aggregation scenario, the method comprising:
acquiring, by the user equipment, a first maximum transmit power of the user equipment corresponding to a first subframe and a second maximum transmit power of the user equipment corresponding to a second subframe; and performing, by the user equipment, power control over transmit power of multiple carriers in an overlap region, so that total transmit power of the multiple carriers in the overlap region after the power control is lower than or equal to a minimum value of the first maximum transmit power and the second maximum transmit power; wherein, the first subframe and the second subframe are adjacent subframes, and the overlap region is a portion in which the first subframe and the second subframe overlap due to a difference in timing advance values of the multiple carriers.
