APPARATUS AND METHOD OF TRANSMITTING PROBING REFERENCE SIGNAL IN UPLINKWIRELESS COMMUNICATION SYSTEMS WITH MULTIPLE ANTENNAE AND PROBING REFERENCE SIGNAL Russian patent published in 2013 - IPC H04B7/04 

FIELD: radio engineering, communication.

SUBSTANCE: invention discloses a method of transmitting a probing reference signal in which a terminal using a multiple antenna technique is equipped with a plurality of antennae, and a base station receives the probing reference signal transmitted from these antennae and estimates the uplink channel state of each antenna. Moreover, the probing reference signal performs frequency hopping so that the base station determines the channel condition for the entire bandwidth to which data is transmitted in the uplink system. The probing reference signal is transmitted through an antenna pattern in which the probing reference signal can be transmitted in the entire data transmission bandwidth of the uplink system for each antenna of the terminal without additional overhead in this environment.

EFFECT: improved method.
