Patent number: 9755712Abstract: A WAP including: a sounding mode module, a sounding matrix generator, a sounding aggregator, a gain normalizer and a beamforming expansion module. The sounding mode module determines whether a number of communication streams supported by the WAP matches the number of streams contained in a sounding response from a station, and initiates a composite set of soundings when those capabilities do not match. The sounding matrix generator generates linearly independent spatial mapping matrices each associated with a corresponding one of the set of composite soundings and at least one reference SMM. The sounding aggregator aggregates partial sounding feedback matrices received from the targeted station node in response to the composite soundings. The gain normalizer normalizes the partial sounding feedback matrices utilizing the reference SMM. The beamforming expansion module expands the aggregated sounding feedback matrices into a full beamforming matrix for spatially mapping downlink communications.Type: GrantFiled: October 11, 2016Date of Patent: September 5, 2017Assignee: Quantenna Communications, Inc.Inventors: Aykut Bultan, Sigurd Schelstraete, Simon John Duxbury

Patent number: 9276653Abstract: A system that facilitates antenna selection and pilot reduction in a multi-antenna system is provided. During operation, in response to an activating event, the system performs a full pilot transmission by transmitting pilot signals through all available transmit antennas at a base station. The system then determines the selected subset of transmit antennas by receiving lists of selected antennas from mobile stations associated with preferred users, wherein a given mobile station selects a list of antennas in response to pilot signals received during the full pilot transmission. The system then combines the received lists to produce the selected subset, wherein the selected subset includes all antennas which appear in the received lists of selected antennas. Next, during normal system operation, the system periodically performs a selected pilot transmission by transmitting pilot signals through a selected subset of the available transmit antennas.Type: GrantFiled: April 10, 2013Date of Patent: March 1, 2016Assignee: Lattice Semiconductor CorporationInventor: Aykut Bultan
