METHOD OF CONTROLLING UPLINK SIGNAL TRANSMISSION POWER AND APPARATUS THEREOF

摘要

The present disclosure relates to a method and an apparatus for allocating or controlling transmission power when a User Equipment (UE) transmits uplink signals. More particularly, the present disclosure relates to a method and an apparatus capable of multiplexing uplink channels or signals from identical base station (e.g., eNB) or between different base stations when the UE transmits various kinds of channels or signals to an uplink in a dual connectivity environment for transmission to or reception from different base stations. The present disclosure provides a method of controlling uplink transmission power by an UE. The method may include determining a maximum uplink transmission power with respect to each cell group of multiple cell groups each including at least one of serving cells, and transmitting uplink channels and uplink signals of each of the multiple cell groups using a maximum uplink transmission power of each one of the multiple cell groups.
