His work focuses on enhancing communication systems, particularly in the areas of channelization codes and neighbor cell notifications.
Latest Patents
Ohto's latest patents include a "Radio control device and method of selecting spread code." This invention aims to prevent the reduction of system capacity caused by the use of a channelization code belonging to the secondary scrambling code. Instead of selecting a channelization code for each primary and secondary scrambling code in a conventional manner, his method attempts to select a channelization code belonging to the primary scrambling code sequentially for multiple cells. If this selection fails, the method allows for a retry under different conditions, subsequently trying the secondary scrambling code.
Another significant patent is the "Neighbor cell notifying apparatus and neighbor cell notifying method." This invention provides a more efficient way to notify a mobile station of neighbor cell information while communicating across multiple cells. The apparatus includes a cell information extracting part that specifies neighbor cells, a cell rank determining part that ranks the neighbor cell information items, and a cell information notifying part that communicates a predetermined number of these items to the mobile station based on their ranks.
