Title:
BASE STATION DEVICE, TERMINAL DEVICE, CONTROL METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2018/087989
Kind Code:
A1
Abstract:
While transmitting a multicast signal to a plurality of terminal devices, a base station device acquires information relating to radio quality from one terminal device that is unable to receive a unicast signal at a timing at which the multicast signal is being received among the plurality of terminal devices, on the basis of the radio quality, determines whether or not to transmit information transmitted by the multicast signal to the one terminal device by unicast, and if determining to transmit the information transmitted by the multicast signal by unicast, transmits a message giving an instruction to stop the reception of the multicast signal and receive a unicast signal to the one terminal device, and transmits the information transmitted by the multicast signal to the one terminal device by the unicast signal.
