Title:
ELECTRONIC DEVICE AND METHOD FOR TRANSMITTING REFERENCE SIGNAL IN ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/131766
Kind Code:
A1
Abstract:
According to various embodiments, an electronic device may comprise a communication processor, an RFIC, an RFFE circuit, and a plurality of antennas, wherein the communication processor transmits a reference signal at configured power on the basis of a path loss configuration value with respect to a transmission path corresponding to each of the plurality of antennas, when target power of the reference signal is larger than the maximum transmission power configured with respect to the reference signal, identifies a difference between the target power of the reference signal and the configured maximum transmission power, and when the difference between the target power of the reference signal and the configured maximum transmission power is equal to or smaller than a configured threshold value, controls to adjust the path loss configuration value with respect to the transmission path corresponding to at least one of the plurality of antennas. Various other embodiments are possible.
