DOWNLINK INTERFERENCE DETECTION USING TRANSMISSION MATRICES

摘要

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.

1. A method of detecting downlink interference in a communications system, the method comprising:
selecting a set of user equipment for measuring interference; generating, for user equipment of the set of user equipment, downlink interference neighbor lists; identifying, for each downlink interference neighbor list, empty resource blocks common to base stations of the downlink interference neighbor list; and analyzing signals received by the set of user equipment during the empty resource blocks to detect interference.
