Abstract: A method for identifying information on an external electronic device based on near field communication (NFC). The method includes transmitting a signal of an NFC band to the external electronic device; identifying whether the external electronic device is capable of NFC, requesting an NFC identifier (ID) from the external electronic device, and receiving the NFC ID from the external electronic device; receiving the NFC ID, reading a unique identifier from the NFC ID, and identifying a communication protocol type; identifying flag information included in the NFC ID; and determining whether the external electronic device is initially recognized and/or normally recognized through the flag information.

Abstract: Disclosed is a method for estimating a channel of a terminal by a base station in a wireless communication system supporting multiple antennas, the method comprising the steps of: estimating a moving speed of the terminal on the basis of a first channel value acquired at a current time point and a second channel value acquired at a previous time point; determining, on the basis of the estimated moving speed, a complexity degree corresponding to the number of channel values for multiple time points including the current time point; and estimating a channel of the terminal at a next time point on the basis of the determined complexity degree.

Abstract: The disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting a higher data rate after a 4th generation (4G) communication systems such as long term evolution (LTE). The disclosure is for reconstructing a downlink channel in a wireless communication system. An operation method for a base station is provided. The operation method includes the steps of transmitting downlink reference signals (RSs) to a terminal, receiving an indication of a first channel matrix estimated by the terminal and at least one uplink RS; estimating a second channel matrix on the basis of the at least one uplink RS, and on the basis of the first channel matrix and the second channel matrix, reconstructing channel information to be used for data transmission.
