20140301216 | UPLINK INTERFERENCE DETECTION USING TRANSMISSION MATRICES - Identifying interference in a cellular network may include creating an interference neighbor list for a target base station that includes a plurality of neighboring base stations, determining a plurality of quiet resource blocks common to the plurality of neighboring base stations and the target base station, and analyzing signals received at the target base station during the plurality of quiet resource blocks. Whether to modify uplink transmission schedules, and the extent of modification, may be determined based on traffic levels. | 10-09-2014 |
20140302796 | DOWNLINK INTERFERENCE DETECTION USING TRANSMISSION MATRICES - A method of detecting downlink interference in a communications system may include selecting a set of user equipment for measuring interference and generating a downlink interference neighbor list for some or all of the user equipment in the set. Empty resource blocks that are common to base stations on each downlink interference neighbor list are identified, and signals that are received by the set of user equipment during the empty resource blocks are analyzed to detect interference. Certain aspects of the method may be practiced before or after an interference detection period. A system for detecting downlink interference is also provided. | 10-09-2014 |
20140335879 | INTERFERENCE DETECTION WITH UE SIGNAL SUBTRACTION - Interference may be detected in a cellular network by receiving signals at a target base station in a quiet resource block in which no uplink transmissions to the target base station are scheduled to occur, identifying a plurality of user equipment attached to base stations neighboring a target base station as interfering user equipment, reconstructing signals transmitted by the interfering user equipment, removing the reconstructed signals from the signals received by the target base station in the quiet resource block, and determining interference in the signals from which the reconstructed signals are removed. Detected interference data can be used to create an interference cancelling receiver. | 11-13-2014 |
