BASIC STATION, USER DEVICE AND METHOD OF SIGNAL TRANSMISSION USED IN MOBILE COMMUNICATION SYSTEM Russian patent published in 2012 - IPC H04B7/06 

FIELD: information technologies.

SUBSTANCE: invention relates to a basic station, a user device and a method used in mobile communication systems using ASTD (Antenna Switching Transmit Diversity) with a feedback. A basic station comprises a storage unit arranged as capable of storing data on quality reflecting conditions of a channel for various transmitting antennas of a user device in a preset frequency band comprising several elements of resources; a planning unit arranged as capable of planning data generation reflecting assignment of resources elements on the basis of quality data; and a transfer unit arranged as capable of transfer of a low-level control signal to a user device, including planning data and antenna selection information. Antenna selection information specifies those transmitting antennas of a user device, which shall be used for transfer. Planning information and antenna selection information jointly go through channel coding.

EFFECT: improvement of error frequency when transferring information on selection of an antenna from a basic station to a user device in case of an ASTD method is applied with a feedback.
