    Abstract: The present disclosure relates to a communication technique for converging, with an IoT technology, a 5G communication system for supporting a higher data transmission rate than a 4G system, and a system therefor. The present disclosure may be applied to intelligent services, such as smart homes, smart buildings, smart cities, smart cars or connected cars, health care, digital education, retail businesses, and security and safety related services, on the basis of 5G communication s technologies and IoT-related technologies. To this end, a communication device may determine control information for a superposition transmission, and acquire selection sources in response to the determined control information. The communication device may transmit a preamble sequence on the basis of the acquired selection sources in a preamble transmission area according to the superposition transmission, and transmit data using the determined control information in a data superposition transmission area according to the superposition transmission.

    IPC: H04W72/04

    Abstract: A method and apparatus perform Uplink (UL) beam tracking in a beamforming-based wireless communication system. A Mobile Station (MS) repeatedly transmits code sequences mapped respectively to MS transmit beams through each MS transmit beam as many times as the number of Base Station (BS) receive beams while sweeping the MS transmit beams. The MS receives, from a BS, transmit beam information indicating at least one best transmit beam selected from the MS transmit beams by the BS, and allocation information used to allocate UL resources for UL feedback. The MS transmits best beam information indicating the at least one best transmit beam and a MS identifier to the BS using the UL resources.

    Abstract: 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). A method for performing device-to-device (D2D) communication by an in-coverage user equipment (UE) in a cellular communication system is provided. The method includes receiving a scheduling grant through a downlink control channel from a base station (evolved Node B (eNB)) and transmitting a scheduling assignment (SA) message in an SA region of a D2D communication frame and data in a data region of the D2D communication frame, based on the scheduling grant, wherein the scheduling grant indicates a resource pattern for transmission (RPT) corresponding to a set of resource units or a subset of a resource unit in a time domain and a frequency domain that is used for transmission of the data.
