METHOD AND APPARATUS FOR DATA TRANSMISSION IN MILLIMETER BASED WIRELESS MOBILE COMMUNICATION

摘要

Provided are a data transmission method and a device thereof. In a mobile communication environment which is configured based on cells applied with a multi-beam scheme based on a millimeter-wave band, beams adjacent to a small cell, which is applied with a beam including a terminal, are selected as interference beams. At the time of transmitting common beam information regarding the beam including the terminal, resource allocation for the common beam information related to the interference beams is restricted. At transmission time, the common beam information related to the beam including the terminal is transmitted through a common beam resource area.
