摘要： The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). The present invention relates to a method and apparatus for channel estimation in a wireless communication system. A method for operating a transmitter comprises the operations of: transmitting a first reference signal through a first antenna; and transmitting a second reference signal through a second antenna, wherein the first reference signal includes a first Golay sequence, and the second reference signal includes a second Golay sequence.

摘要： An electronic device includes a Wi-Fi module configured to perform communication in a first frequency band, a communication module configured to wirelessly communicate with a given network in a second frequency band, a first processor operatively connected to the communication module, a second processor operatively connected to the Wi-Fi module and the first processor, and a memory operatively connected to the second processor. The memory may store instructions, that when executed by the second processor, cause the second processor to receive, from the first processor, a message notifying a state of the electronic device wirelessly communicating with the given network and to lower transmit power of the Wi-Fi module in response to the message.

摘要： Disclosed is a 5G or pre-5G communication system to be provided so as to support a data transmission rate higher that of a 4G communication system such as LTE. According to one embodiment of the present invention, a method for receiving data in a wireless communication system by using a channel bonding scheme can comprise the steps of: monitoring reception of a preamble in a preset minimum bandwidth of the entire channel-bondable bandwidth; acquiring data transmission bandwidth information and switching interval time information from the preamble when the preamble is to be received; and receiving data by switching from the minimum bandwidth to the data transmission bandwidth for the acquired switching interval time.
