SYSTEMS AND METHODS TO COORDINATE TRANSMISSIONS IN DISTRIBUTED WIRELESS SYSTEMS VIA USER CLUSTERING Russian patent published in 2015 - IPC H04B7/216 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to distributed wireless communication systems and discloses coordination of transmissions in distributed wireless communication systems via user clustering, particularly a method which comprises steps of: measuring link quality between a target user and a plurality of distributed-input distributed-output (DIDO) distributed antennae of base transceiver stations (BTS); using the link quality measurements to define a user cluster; measuring channel state information (CSI) between each user and each DIDO antenna within a defined user cluster; and precoding data transmissions between each DIDO antenna and each user within the user cluster based on the measured CSI.

EFFECT: facilitating clustering in communication networks.
