INTERFERENCE DETECTION USING DEDICATED RANDOM ACCESS PREAMBLE

摘要

There are provided measures for interference detection using a dedicated random access preamble, such as e.g. in layered heterogeneous network deployments. Such measures may exemplarily comprise measures for providing interference detection assistance information, relating to detection of a dedicated random access preamble which is specified for interference detection, from a first network communication entity to a second network communication entity, detecting reception of the dedicated random access preamble and the received power of the dedicated random access preamble at the second network communication entity, determining whether or not an interference-related operation is to be performed by the second network communication entity based on the obtained interference detection assistance information and the detected received power of the dedicated random access preamble, and executing interference detection on the basis of monitoring of the interference-related operation performed by the second network communication entity at the first network communication entity.
