Reduction Of False Alarms In PDCCH Detection

摘要

Methods and systems for determining scheduling information of a base station in a network operating according to the Long Term Evolution (“LTE”) standard include monitoring transmissions on the PDCCH of the wireless base station, maintaining a list of active Radio Network Temporary Identifiers (“RNTI's”) assigned by the wireless base station to user equipment, extracting PDCCH detections from the monitored transmissions, applying at least one false alarm reduction strategy to eliminate invalid PDCCH detections from the extracted PDCCH detections, said false alarm reduction strategy including determining an RNTI that is valid for an extracted PDCCH detection and determining if the valid RNTI is included in the list of active RNTI's. Scheduling information of the wireless base station is determined from the extracted PDCCH detection.

1. A method of determining scheduling information of a base station in a network operating according to the Long Term Evolution (“LTE”) standard, the method comprising:
monitoring transmissions on the Physical Downlink Control CHannel (“PDCCH”) of the wireless base station; maintaining a list of active Radio Network Temporary Identifiers (“RNTI's”) assigned by the wireless base station to user equipment; extracting PDCCH detections from the monitored transmissions;applying at least one false alarm reduction strategy to eliminate invalid PDCCH detections from the extracted PDCCH detections, said false alarm reduction strategy including determining an RNTI that is valid for an extracted PDCCH detection, determining if the valid RNTI is included in the list of active RNTI's, and comparing PDCCH detections with each other to determine whether a PDCCH detection is invalid based on an apparent parameter change between compared PDCCH detections; and
determining scheduling information of the wireless base station from the extracted PDCCH detections.
