Abstract: A hybrid combination of analog RF beamforming and digital pre-coding is used to improve signal-to-noise ratio and mitigate interference as between an RF base station and a plurality of wireless receivers within a cell area of the base station. Feedback overhead for beamforming training may be reduced by using indices for identifying the preferred beams of each wireless receiver. Scheduling for channel training may be based on identifying non-colliding ones of the RF beams and assigning these to corresponding wireless receivers which can best use the assigned beams in shared transmission slots.

Abstract: A routing technique provides a routing table which assigns weights in the process of selecting a next hop at a router, while still using an equal cost multipath selection process at the router. The routing table is configured to cross reference an IP address prefix set to a number of next hops which can be all, or fewer than all, available next hops. This occurs in each row of the table for a different IP address prefix set. Subsets of the next hops are identified in each row in a manner which results in the next hops being selected according to specified weights. An estimate of traffic to the different IP address prefix set is also considered. The routing table can be configured based on announce and withdraw messages received from a link weight translator of a controller.

Abstract: A processor implemented method of identifying a root cause of degraded network quality in a wireless network. The method includes accessing historical network performance data, the performance data including a time sequenced measure of performance indicators for the network. The method evaluates the historical performance data to determine regularly occurring associations between indicators to define a set of rules characterizing the associations of the wireless network, and stores the set of rules in a data structure. The wireless network is monitored by accessing analysis data reporting time sequenced performance indicator data. Next, anomalies are detected in a performance indicator in the analysis data and matched to at least one rule in the set of rules. The method outputs an indication of a cause of degradation in the wireless network resulting from the anomaly in the performance indicator.
