    摘要： A distributed controller of local radio resources implements a hybrid FFR system. The distributed controller provides user channel information to a central controller of regional radio resources. The distributed controller also obtains an FFR plan from the central controller. The FFR plan designates for an access point associated with the distributed controller, a central frequency band, an edge frequency band, and a distribution of user devices connected to the access point. The distribution indicates whether each user device communicates with the access point via the central frequency band or via the edge frequency band. The distributed controller provisions the access pint to connect to the user devices according to the FFR plan, and adjusts the distribution of user devices locally based on a change in the user channel information.

    摘要： Techniques presented herein may provide Distributed Unit (DU) failover techniques for a virtualized Radio Access Network (vRAN) architecture. In one example, a method may include maintaining, by a management node for a vRAN, service information for a plurality of distributed unit components for the vRAN in which the service information identifies, at least in part, service characteristics and failover rules for the vRAN. The method may further include determining a failure of a particular DU component of the plurality of DU components; and reassigning one or more particular RUs currently assigned to the particular DU component to one or more other DU components based on the service characteristics maintained in the service information and particular failover rules identified in the service information that are associated with each of the one or more particular RUs that are re-assigned.

    摘要： Presented herein are techniques to optimize wireless local area network access point beam settings. A method includes, during a survey period, causing a first access point and a second access point in a wireless local area network, to simultaneously transmit survey transmissions according to a predetermined sequence of transmission states, receiving, from a survey station that received the survey transmissions during the survey period, telemetry associated with the survey transmissions, the telemetry including a location of the survey station when the survey station received the survey transmissions, and after the survey period, controlling, based on the telemetry associated with the survey transmissions, the first access point to operate according to a first transmission state from among the transmission states and the second access point to operate according to a second transmission state from among the transmission states.

    摘要： A method for adaptive presence-based radio configuration of access points in a venue includes defining a number of regions in the venue in which access points are deployed, each region having a center point, and assigning a first access point to a first region, positioned at the center of the first region. The method also includes affecting a first energy level in the first region, which corresponds to a power of a transmit signal emitted by the first access point, and assigning to the first region a configurable capacity value that determines an acceptable overlap constraint between the first energy level of the first region and an energy level of a neighboring region. The method further includes generating data describing a tessellation graph in which a possible map of the access points is formed using an iterative descent process based on the first energy level and the overlap constraint.

    摘要： Ultra-Wideband (UWB) ranging and location tracking, and particularly an UWB antenna array system and methods for improving the accuracy for Phase-Difference-of-Arrival (PDOA) is provided. UWB ranging may include receiving a poll signal from a client via a first and second antenna. PDOA between the first and second antenna is determined based on the poll signal. A response signal is transmitted to the client, and a first portion of a final signal is received via the first antenna and a third antenna and a second portion of the final signal is received via the second and third antenna. PDOA between the first and third antenna is determined based on the first portion, and PDOA between the second and third antenna is determined based on the second portion. The client location is then determined based on the PDOAs.
