Abstract: There is provided a tag device including a first sensor, a second sensor, a pre-processor and a neural network processor. The pre-processor generates first position data of the tag device based on time information sensed by at least one of a third sensor included in each of the one or more anchor devices and the first sensor of the tag device, generates second position data based on first speed data of the tag device sensed by the second sensor and the first position data, and generates an image based on a path of movement of the tag device based on the second position data in an operation period, and the neural network processor classifies the image into one of a plurality of movements by using a trained neural network model.

Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The present invention relates to a method and an apparatus for estimating an uplink channel of a base station in a wireless communication system, comprising the steps of: estimating a position of a wireless channel tap on the basis of a sounding reference signal (SRS) received from a terminal; determining an average power value of the wireless channel tap for each link between a transmitting antenna and a receiving antenna from and to which the SRS is transmitted; and estimating an effective channel frequency response (effective CFR) of a physical uplink shared channel (PUSCH) on the basis of the position of the wireless channel tap and the average power value of the wireless channel tap.

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.

Abstract: Disclosed is a 5th generation (5G) or pre-5G communication system for supporting a data transmission rate higher than that of a 4th generation (4G) communication system, such as long term evolution (LTE). The purpose of the disclosure is to detect interference between base stations in a wireless communication system, and a base station operating method can comprise the steps of: receiving signals through a resource allocated for reference signals (RSs) for interference measurement; detecting at least one RS on the basis of the signals; and determining that at least one among the RSs has been received on the basis of cross-correlation values between candidate RSs.
