Abstract

The present disclosure relates to a fifth-generation (5G) or pre-5G communication system to support a higher data transmission rate, following a fourth-generation (4G) communication system including long term evolution (LTE). A method for operating an electronic device is provided. The method includes determining the properties of a first signal and a second signal that are transmitted through different frequency bands and performing line-of-sight (LoS) determination based on the determined properties of the first signal and the second signal.
