Title:
SIGNAL PROCESSING DEVICE, RADIO DEVICE, FRONTHAUL MULTIPLEXER, BEAM CONTROL METHOD AND SIGNAL SYNTHESIS METHOD
Document Type and Number:
Japanese Patent JP2019012937
Kind Code:
A
Abstract:
To provide a signal processing device capable of individually controlling beam directions of a plurality of radio devices downstream of a fronthaul multiplexer.SOLUTION: A signal processing device performs communications with a plurality of radio devices operable to performing radio communications with user terminal devices through a fronthaul multiplexer. The signal processing device comprises: a storage section for storing pieces of beam information by which respective pieces of device ID information of the plurality of radio devices is associated with pieces of beam ID information assigned to beams formed by the plurality of radio devices so as to differ from each other among the beams; a transmit section which transmits the pieces of beam information to the plurality of radio devices through the fronthaul multiplexer; and a receiving section which receives pieces of beam ID information assigned to beams of the best communication quality, which the plurality of radio terminal devices have received from the user terminal devices, from the plurality of radio terminal devices through the fronthaul multiplexer.SELECTED DRAWING: Figure 7
