This article aims to shed light on his latest patents, notable career achievements, collaborations, and overall impact on the industry.

Latest Patents:

Among Imamura's recent inventions, the patent "Terminal Apparatus and Sequence Assigning Method" stands out. This groundbreaking method efficiently allocates ZC (Zadoff-Chu) sequences as reference signals in mobile communication systems, ensuring reduced inter-cell interference. By dividing R×M sequences, determined by ZC sequence numbers (r=1 to R) and cyclic shift sequence numbers (m=1 to M), into multiple sequence groups X (X=1 to R), the reference signal's transmission bandwidth is optimized. With R=9 and M=6, 54 sequences are generated and arranged into 27 sequence groups, which are thoughtfully assigned to respective cells.

Another noteworthy patent by Imamura is the "Radio Transmission Device and Radio Transmission Method." This invention addresses the need for improved downlink and uplink throughput while employing dynamic symbol allocation. By sharing a correlation table between the Base Station (BS) and Mobile Station (MS), which includes parameters like TB size, allocation RB quantity, modulation method, and encoding ratio, efficient transmission of user data is achieved. This method supports multiplexing L1/L2 control information, with the BS reporting the corresponding index for the basic TF to the MS, enabling enhanced performance.
