Publication number: 20240079771Abstract: A redirecting rotating mirror arrangement includes a directional antenna subcomponent having a direction of maximum received or transmitted beam intensity. The redirecting rotating mirror arrangement also includes a rotatable mirror that reflects an electromagnetic beam to or from the directional antenna subcomponent. The rotatable mirror is inclined at an inclination angle with respect to a horizontal plane. The arrangement also includes a motor that rotates the rotatable mirror about the direction of maximum received or transmitted beam intensity such that the electromagnetic beam is either received from or transmitted to a range of angles as the rotatable mirror rotates.Type: ApplicationFiled: January 14, 2022Publication date: March 7, 2024Applicants: UNIVERSITY OF SOUTHERN CALIFORNIA, TECHNISCHE UNIVERSITÄT WIENInventors: Andreas MOLISCH, Christoph MECKLENBRAEUKER, Thomas POHL, Hussein HAMMOUD, Yuning ZHANG

Patent number: 11489559Abstract: Described are devices, systems and methods for scheduling multi-user (MU) multiple input multiple output (MIMO) transmissions in a fixed wireless access (FWA) system. One method for scheduling a large number of user devices in a wireless communication system includes a preselection process to pare down the number of user devices to be simultaneously scheduled, and then scheduling that subset of users. In an example, and assuming each user device communicates over a corresponding wireless channel, the preselection process includes determining a number of sets based on a first characteristic of the wireless channels, where each set includes at least one user device, and then determining a subset of user devices by selecting at most one user device from each of the sets. The scheduling of the selected subset of users is based on a scheduling algorithm and a second characteristic of the wireless channels.Type: GrantFiled: March 8, 2019Date of Patent: November 1, 2022Assignee: Cohere Technologies, Inc.Inventors: Andreas Molisch, Robert Fanfelle, Saurabh Misra, Paul Lind, James Delfeld
