Patent number: 10887039Abstract: A wireless network is provided that includes a base station and subscriber stations that communicate with the base station using radio frequency (RF) time division duplex (TDD) signaling. The base station may establish medium access control (MAC) connections with each station. The base station monitors communications with the stations and, in accordance, assigns stations or MAC connections to modulation groups. The base station transmits signals on MAC connections or to stations in a modulation group in adjacent TDD slots within a TDD frame. The base station may receive access requests from the stations, evaluate traffic requirements for the stations, and determine a longest downlink portion for the stations. The base station then allocates downlink and uplink portions of a TDD frame according to the length of the longest downlink portion.Type: GrantFiled: November 13, 2018Date of Patent: January 5, 2021Assignee: GENERAL ACCESS SOLUTIONS, LTD.Inventors: Paul F.

Patent number: 10820312Abstract: TDD access equipment modified by introducing a frequency change at the normal TDD guard point, with respective downlink or uplink periods for individual subscriber stations offset to form overlapping frames. Cyclo-stationary processing, block equalization, and burst timing coordination allow the boundary between downlink and uplink portions of both frames to be set dynamically, improving spectral efficiency. Fast frequency switching within an allotted physical slot enables synchronization of time-sharing the dedicated frequencies to be maintained among subscriber stations. Duplex spacing between downlink and uplink frequencies for individual subscriber stations, combined with in-depth filtering of received signals, prevents spurious out-of-band transmission signal strength from reaching an interference level.Type: GrantFiled: April 15, 2019Date of Patent: October 27, 2020Assignee: General Access Solutions, Ltd.Inventor: Paul F. Struhsaker
