Abstract

Provided is a method and apparatus for transmitting and receiving data using a polarization transmission in a line-of-sight (LOS) radio communication system. An for transmitting data using a polarization transmission in a LOS radio communication system may include: an antenna unit including at least two antennas to transmit or receive via a different polarization path; a polarization data setting unit to set the different polarization path for each of the at least two antennas; and a resource allocation unit to set a transmission scheme according to a data characteristic and a service type, and to allocate a resource to be transmitted via the different polarization path according to the transmission scheme.

Dependent claims

A method of transmitting data using a polarization transmission in a transmission apparatus of a line-of-sight (LOS) radio communication system, the method comprising:

setting a different polarization path for each of at least two antennas as independent channels usable simultaneously;
connecting the polarization path and an antenna of a reception apparatus through an antenna training sequence;
determining a transmission scheme according to a data characteristic and a service type;
and
transmitting the data using the determined transmission scheme,
wherein the transmission scheme receives reception data of a control signal by using at least one of different polarization paths as an uplink and simultaneously transmits transmission data of unidirectional stream data by using at least one of the remaining polarization paths as a downlink.
