Patents by Inventor Morteza Hashemi

Morteza Hashemi has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10869256
    Abstract: A wireless communication apparatus, system or method utilizing for performing data transmission over a communication band (e.g., directional mmW) which maintains a primary and at least one backup route for communications between a source and destination station. Route discovery messages are sent to neighboring stations in creating a route over multiple hops. Along the routing path link metrics are determined which are shared with other stations. Route discovery and routing response messages are propagated to neighbor stations aside from the sending station. The destination station, upon receiving the route discovery message, determines a primary route and at least one backup route, and sends this information in a route reply message back to the originator of the route discovery message. Stations maintain these primary and backup routes through status request and status reply messages.

  • Patent number: 10849048
    Abstract: A wireless communication apparatus, system or method utilizing for performing data transmission over a communication band (e.g., directional mmW) which maintains a primary and at least one backup route for communications between a source and destination station. Route discovery and response messages are utilized along with route request and reply update messages in maintaining primary and one or more backup routes from a source to destination station. Locally overcoming blockage conditions to select another route if it is available, and communicating route status information to neighbor stations, with each station proactively assuring that its routing table entries are up-to-date and that multiple next-hop options are reachable and ready to be deployed at any time.

  • Patent number: 10798636
    Abstract: A wireless communication apparatus, system or method to perform directional wireless transmission (e.g., directional mmW) after establishing one or more routes. When valid routes are not available for sending route discovery, then sector sweeping (SSW) is performed which combines a routing request with the SSW frame sent in multiple sector directions for receipt by neighboring stations. These neighboring stations obtain the information from the SSW and its appended routing request and respond back to the initiator with an SSW to which may be appended a routing reply or a routing request. Beam refinement is performed by appending a training field onto a route request, which is responded to by appending a beam refinement reply onto a route reply.
