Problems solved by technology

However, since the coverage of the existing LTE network is designed to be optimized to the terminal's maximum output power of 23 decibel-milliwatts (dBm), during carrier aggregation operation for each The average output power of the carrier is reduced by 3dB, and the problem of insufficient output power in the terminal may occur especially near the cell edge area
Such issues can lead to poor quality of service, for example, call drops during the use of certain services such as VoLTE

Abstract

The present invention relates to a method for controlling an output of a terminal and, more specifically, to a method for controlling a terminal output in a carrier aggregation (CA) operation, which is capable of controlling the service quality of a terminal by controlling an output which is transmitted so as to allocate more outputs to a main cell when a preset bearer, such as VoLTE, is generatedwhen the terminal operates in a CA mode.

Description

technical field [0001] The present disclosure relates to a method of controlling output power of a terminal, and more particularly, to a carrier aggregation operation in which the output power for each carrier is variably controlled according to the type of service to control the quality of service of the terminal when the terminal performs the carrier aggregation operation A method of controlling the output power of the terminal during the period. In addition, the present disclosure relates to apparatus suitable for the method. Background technique [0002] The descriptions in this section only provide background information for the implementations of the disclosure and are not intended to identify prior art to the present disclosure. [0003] As mobile communication technology evolves, carrier aggregation, which combines two or more carriers into one data channel, has been introduced into mobile communication systems in order to increase channel bandwidth between a termin...
