RADIO BASE STATION, MOBILE STATION AND RADIO COMMUNICATION METHOD Russian patent published in 2014 - IPC H04J11/00 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to a mobile communication system which defines a multiple input multiple output (MIMO) scheme as a radio transmission method, and is intended to increase the number of transmission levels. A radio base station (20) has a plurality of transmitting antennae, a module (22) for generating an orthogonal sequence of a reference signal, which is designed to generate orthogonal reference signals based on a two-dimensional orthogonal code, wherein the orthogonal reference signals are made orthogonal between downlink reference signals, adjacent to each other on two axes in the direction of the frequency axis and the direction of the time axis at one transmission level, and are made orthogonal at different transmission levels assigned to one radio communication resource, a multiplexer (23) designed to multiplex transmitted data and orthogonal reference signals at one transmission level, and a transmitter designed to transmit a transmitted signal, which is obtained by multiplexing transmitted data and orthogonal reference signals using a transmitting antenna simultaneously at transmission levels.

EFFECT: improved communication.
