SYSTEMS AND METHODS FOR MAPPING VIRTUAL RADIO-CHANNELS INTO PHYSICAL VOLUMES OF COHERENCE IN DISTRIBUTED ANTENNA SYSTEMS Russian patent published in 2020 - IPC H04L27/00 

FIELD: radio engineering and communications.

SUBSTANCE: invention relates to a system for mapping virtual radio channels (VRI) into physical volumes of coherence in a multi-antenna system (MAS) with multi-user (MU) data transmission (MU-MAS). Multi-user multi-antenna system ("MU-MAS") comprises: one or multiple radio access networks (RAN), comprising a plurality of distributed transceiver stations and one or more virtual units for processing a baseband with the implementation of a plurality of wireless protocols. Distributed receiving-transmitting stations transmit or receive a plurality of signals, which interfere with each other in space, and MU-MAS uses pre-coding to use spatial diversity, to make a plurality of wireless protocols available simultaneously in the same frequency band at location of user devices without interference.

EFFECT: technical result of the invention is to perform simultaneous transmission of noninterfering data streams in the same frequency band between the MU-MAS system and a plurality of users within their coherence range, which eliminates need for relay data transfers and unnecessary redundancy of control data.
