Abstract: A method of determining the topology of a portion of the electrical distribution grid such as a feeder based on voltage and current measurements. The method employs Bayesian-based topology detection, where voltage and current data is measured at switches in the feeder at numerous sample times. A voltage variance is calculated for each switch, along with a voltage correlation coefficient for each pair of switches. Voltage variance is used to establish a preliminary position of a switch in the feeder, where switches closest to the substation source are expected to exhibit the least variance, and vice versa. The voltage correlation coefficient is used to provide a first determination of whether two switches are in series with each other in a parent-child relationship, and a current magnitude comparison is used to confirm or refute the preliminary parent-child relationship between the two nodes.

Abstract: To employ beamforming to increase signaling distances, one wireless device trains a beamformer using a signal being received from another wireless device. The trained beamformer can then communicate with the other device via a signal beam until channel conditions change. In example implementations, a base station (BS) reserves an air interface resource unit for beamformer training in conjunction with allocating an air interface resource unit for downlink data. The BS transmits a downlink control channel communication to a user equipment (UE) with a downlink data grant indicative of the allocated resource unit. During the reserved resource unit, the UE transmits an uplink tracking communication, which can include a pilot signal, to the BS for beamform training. The BS then uses the freshly trained beamformer to transmit the downlink data as a downlink data channel communication via a downlink beam during the allocated resource unit.
