SYSTEMS AND METHODS TO COORDINATE TRANSMISSIONS IN DISTRIBUTED WIRELESS SYSTEMS VIA USER CLUSTERING

摘要

The system and method are described in coordinating the transmission of distributed wireless systems through user clustering. For example, a method according to an embodiment of the present invention includes: measuring link quality between a distributed antenna having a plurality of distributed input distributed outputs of base transceiver stations (BTSs) and a target user; Using link quality measurement to define a user cluster; Measuring channel state information (CSI) between each DIDO antenna and each user in the defined user cluster; And precoding data transmission based on the measured CSI between DIDO antennas in the user cluster and a user reachable by the DIDO antennas.
