Patent number: 11843552Abstract: A fixed wireless access system is implemented using orthogonal time frequency space multiplexing (OTFS). Data transmissions to/from different devices share transmission resources using—delay Doppler multiplexing, time-frequency multiplexing, multiplexing at stream and/or layer level, and angular multiplexing. Time-frequency multiplexing is achieved by dividing the time-frequency plan into subgrids, with the subsampled time frequency grid being used to carry the OTFS data. Antenna implementations include a hemispherical antenna with multiple antenna elements arranged in an array to achieve multiplexing.Type: GrantFiled: January 13, 2023Date of Patent: December 12, 2023Assignee: Cohere Technologies, Inc.Inventors: Shlomo Selim Rakib, Ronny Hadani, Richard Benner, Robert Fanfelle

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
