Title:
ELECTRONIC DEVICE FOR SUPPORTING DUAL CONNECTIVITY, AND METHOD FOR CONTROLLING ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/153811
Kind Code:
A1
Abstract:
The present invention relates to an electronic device, comprising: at least one first antenna that transmits and receives a first signal; at least one second antenna that transmits and receives a second signal; and a modem that, when connected to a first network and a second network at the same time, determines a maximum transmission power of the first signal and a maximum transmission power of the second signal on the basis of a ratio of maximum transmission powers according to the dual connectivity to the first network and the second network, updates, in each preset period, the maximum transmission powers of the first signal and the second signal according to a first path loss and a second path loss for the first signal and the second signal, and controls amplification gains of at least one first power amplifier connected to the first antenna and at least one second power amplifier connected to the second antenna according to the updated maximum transmission powers.
