Abstract: Example implementations involve systems and methods for combining disparate information available in an enterprise network, and utilize the information to predict the WiFi traffic at a given access point at a given instance of time. Example implementations further involve systems and methods that utilize policies to optimize performance when traffic is high. Example implementations may thereby improve overall efficiency and reliability of the Enterprise Wifi network.

Abstract: Example implementations described herein are directed to systems and methods that utilize adaptive antenna arrays that include one or more antennas at the user equipment (UE) to dynamically steer the antenna response at the UE to improve system performance. The improvement is achievable in both downlink and uplink. The example implementations described herein also involve details of the associated signaling. The UE sends feedback measurement signals related to the position and orientation of the UE to the base station, wherein the base station calculates and provides antenna response parameters for the UE based on the received feedback.

Abstract: Example implementations described herein are directed to operation of heterogeneous networks with dynamic reconfiguration of network parameters of a base station such as antenna tilt, to optimize the deployment of base stations and antennas in the network. In example implementations, associated user equipment and/or base stations derive a feedback consensus for estimating an optimization of one or more of the network parameters based on one or more metrics such as channel quality. Based on the one or more metrics, the feedback consensus is reached iteratively for the network parameters, and the base station is then informed of the optimized estimation of the network parameters.

Abstract: Example implementations described herein are directed to methods for low-complexity grouping of UEs and base stations that also take into account traffic loads of candidate serving cells, base station and UE capabilities, and wireless link quality. In example implementations, a base station receives measurement information from associated user equipment and reporting information from neighboring base stations to calculate grouping assignments for the associated user equipment and/or the neighboring base stations.
