Latest Patents

One of his latest innovations is centered around an Orthogonal Frequency Domain Multiplexing (OFDM) communication system. This system incorporates a cell time division framework which involves multiple overlapping cells. The time frame consists of various time slots, with each allocated to a cell and designated as either an information exchange or data time slot. This inventive system allows remote nodes to send resource requests for subcarriers within designated data time slots. In response, central nodes broadcast information regarding uplink channel characteristics, aiding remote nodes in deciding whether to proceed with their resource requests. This innovation promotes effective distributed multi-cell resource allocation.

Another significant patent involves a wireless communication unit designed for a radio communication system. It utilizes a device token controller that manages geographical radio resource tokens allocated to the unit. By determining radio resource usage parameters based on these allocations, Grandblaise's invention supports both centralized and distributed radio resource management, making it particularly valuable in heterogeneous communication systems.
