Title: The Innovations of David R. Maas
Introduction
David R. Maas is a notable inventor based in Hoffman Estates, Illinois. He has made significant contributions to the field of communication systems, holding a total of five patents. His work primarily focuses on optimizing data transmission in orthogonal frequency division multiplexing (OFDM) communication systems.
Latest Patents
One of his latest patents is titled "Method and apparatus for scheduling downlink transmissions in an orthogonal frequency division multiplexing communication system." This invention enhances adaptive scheduling by considering both present and past reported Channel Quality Indicator (CQI) values. It executes a 'dithering' function to select a Modulation and Coding Scheme (MCS) that is intermediate between adjacent discrete MCSs. The system determines a first MCS based on a channel quality metric received from a mobile station and transmits data using this MCS. Additionally, it assigns weights to the first and second MCS based on data acknowledgment and selects one for subsequent transmissions.
Another significant patent is "Method and apparatus for uplink scheduling in an orthogonal frequency division multiplexing communication system." This invention optimizes the utilization of an uplink data packet field. It involves receiving bandwidth allocation requests from multiple mobile stations, which are prioritized based on size. When the allocated bandwidth does not fill the uplink data packet field, the system substitutes unallocated requests of a larger size for smaller ones, ensuring efficient bandwidth usage.
Career Highlights
David R. Maas is currently employed at Motorola Mobility LLC, where he continues to innovate in the field of communication technology. His work has been instrumental in advancing the efficiency of data transmission systems.
