KDDI had one patents in advanced materials during Q2 2024. The patent filed by KDDI Corp in Q2 2024 describes a relay device that relays a predetermined signal from a base station device through different radio wave output directions without decoding user data. The device controls the relay of the signal in different directions based on the time slot and selects the output direction for signal transmission between a terminal device and the relay device based on the timing of receiving a second predetermined signal from the terminal device.

Application: Relay device for relaying communication between base station device and terminal device by forming a beam, control method, and computer-readable storage medium (Patent ID: US20240171258A1)
The patent filed by KDDI Corp describes a relay device that relays signals from a base station to a terminal device through a predetermined beam without decoding user data. The device controls the relayed signal direction based on time slots and selects the output direction for signal transmission based on the timing of a second predetermined signal received from the terminal device.
The relay device includes a relay unit, control unit, and selection unit to perform the signal relaying and direction selection functions. The device can function as a wireless repeater or reflector, with the selection unit choosing the output direction based on the relationship between the timing of the second predetermined signal and different periods associated with each radio wave output direction. Additionally, the device can identify terminal devices and select output directions accordingly. The patent also covers a control method and computer program stored on a non-transitory storage medium for implementing the relay device's functions.
