The close-proximity communication method performed by a transmitter includes generating a physical layer (PHY) frame including a PHY preamble, a frame header, and a payload field, and transmitting the generated PHY frame to a receiver, in which the frame header may include a media access control (MAC) header, a header check sequence (HCS), and a Reed-Solomon (RS) parity bit.
Abstract:
A method of determining a position of a terminal in a communication system using multiple beams is provided. The method includes receiving a first beam from a first point, receiving a second beam from a second point, and determining a position of the terminal by use of information about the first beam and information about the second beam, so that in a case in which two or more effective beams are received in a system using multiple beams, the position of the terminal is determined by use of the angle of a beam, and information about coordinates of departure of a beam and/or coordinates of final arrival of a beam without using a positioning device, such as GPS.
