METHOD AND TERMINAL FOR TRANSMITTING UPLINK SIGNAL BY REDUCED POWER IN INTRABAND NON-CONTIGUOUS UPLINK CARRIER AGGREGATION

摘要

One embodiment of the present specification relates to a method for reducing transmission power. The method for reducing transmission power can comprise the steps of: determining whether set carrier aggregation (CA) corresponds to intra-band non-contiguous CA when the CA is set; determining transmission power by applying maximum power reduction (MPR) when the set CA corresponds to intra-band non-contiguous CA; and reducing power by applying additional MPR to the determined transmission power in order to protect adjacent bands when non-contiguous carriers belong to a specific band.

1. A method of reducing transmission power, the method comprising:
if a carrier aggregation (CA) is configured, determining whether the configured CA corresponds to intra-band non-contiguous uplink CA; if the configured CA corresponds to the intra-band non-contiguous uplink CA, determining transmission power by applying a maximum power reduction (MPR); and if the non-contiguous uplink carriers belong to a specific band, performing power reduction by applying an additional MPR to the determined transmission power to protect an adjacent band.
