Abstract
The technology in this application reduces the maintenance effort and expense to monitor the performance of a cellular radio access node (e.g., a relay or repeater) by having the cellular radio access node automatically perform radio performance monitoring on itself and providing some kind of indication of its status to an operations and maintenance node. The cellular radio access node monitors performance of a set of one or more radio characteristics of a received radio signal received by the cellular radio access node or a transmitted radio signal transmitted by the cellular radio access node and determines whether the performance exceeds an associated predetermined threshold. The cellular radio access node indicates a condition of the cellular radio access node for the operations and maintenance node based on the monitored performance. The cellular radio access node may take independent action, e.g., shutdown, restart, reduce transmit power, etc., if a monitored condition is exceeded, e.g., transmitted noise exceeds a threshold.
