Title:
METHOD AND DEVICE FOR PROVIDING REMOTE INTERFERENCE MANAGEMENT REFERENCE SIGNAL, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/075724
Kind Code:
A1
Abstract:
According to various embodiments, an electronic device in a wireless communication system comprises a communication circuit, a memory, and at least one processor, wherein the memory can store instructions that allow, during the execution thereof, at least one processor to perform the operations of: identifying the difference between a carrier frequency for communication with a terminal and a reference point set for a remote interference management (RIM) reference signal (RS); identifying a first share obtained by dividing the difference into subcarrier intervals, and the remainder; rotating 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, on the basis of 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 rotating the phase of at least one subcarrier in the second OFDM symbol on the basis of the carrier frequency and/or the remainder. Other embodiments are also possible.
