Latest Patents

Futami's latest patents include a radio communication apparatus and communication method. This invention involves a radio communication apparatus designed to form a frame with multiple slots, incorporating a guard interval into each slot along with data for mobile stations. The apparatus features a receive state acquisition section that monitors the receive state of each mobile station. Additionally, a frame format decision section determines the frame format with varying guard interval lengths for each slot based on the mobile stations' receive states. The slot assignment section allocates each slot to data for the respective mobile stations, while the frame format reporting section communicates the decided frame format to the mobile stations via a reporting channel. This allows mobile stations to identify the guard interval length based on the reported frame format and slot number, enabling efficient communication.

Another notable patent involves a mobile communication system, including a base transceiver station apparatus and mobile station apparatus. In this system, a phase error detector in the base transceiver station identifies phase errors caused by Doppler shifts in received waves from mobile stations. A phase rotator then adjusts the phase of transmission symbols in the baseband region to counteract the Doppler shift occurring in the downlink from the base transceiver station to the mobile station.
