US 12,706,714 B2 · Method and device for providing remote interference management reference signal, and storage medium

Abstract

An electronic device in a wireless communication system is provided. The electronic device includes a communication circuit, a memory, and a processor, wherein the memory stores instructions that cause the processor to identify a difference between a carrier frequency for communication with a terminal and a reference point set for a remote interference management (RIM) reference signal (RS), identify a first share obtained by dividing the difference into subcarrier intervals, and the remainder, rotate the phase of at least one subcarrier in a first orthogonal frequency-division multiplexing (OFDM) symbol including at least the other part of the RIM RS, based on at least one from among a cyclic prefix (CP) length of a second OFDM symbol including at least a part of the RIM RS, the carrier frequency, and the remainder, and rotate the phase of a subcarrier in the second OFDM symbol based on the carrier frequency.
