US Patent 9572055 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.
