The present disclosure relates to a communication scheme and system which fuse a 5G communication system for supporting a higher data transfer rate than a 4G system with IoT technology, and a system thereof. The present disclosure may be applied to smart services such as smart homes, smart buildings, smart cities, smart cars or connected cars, healthcare, digital education, retail businesses, security and safety services, etc., based on 5G communication technologies and IoT related technologies. The communication method with a device according to the present invention comprises the steps of: transmitting information on frequency hopping settings to the device; and receiving, from the device, an uplink signal which hops frequencies according to the frequency hopping settings, wherein the frequency hopping settings are configured in a way that the uplink signal hops frequencies according to hopping patterns which hop according to frequency hopping steps, and to additional mirroring hopping patterns which are respectively inserted between the hopping patterns.

Method and apparatus for communication in cellular IoT network

A communication method and apparatus for cancelling interference are provided. The communication apparatus includes an active element configured to receive a first signal and a parasitic element configured to receive a second signal. A third signal is generated by cancelling interference in the first signal using the second signal.

Communication method and apparatus

Provided is an access point grouping method to be performed in a high speed mobile environment and a communication system using the access point grouping method. A system capacity may be improved by grouping users having different movement speeds with respect to various channel environments classified based on existence of an LOS channel, and by performing beamforming. Channel information with respect to a user moving at a high speed may not be required, and thus overhead may be reduced.
