Title:
BASE STATION DEVICE, TERMINAL DEVICE, CONTROL METHOD, AND PROGRAM FOR PERFORMING EFFICIENT COMMUNICATION
Document Type and Number:
WIPO Patent Application WO/2024/042841
Kind Code:
A1
Abstract:
This base station device transmits, to a terminal device having a first transceiver and a second transceiver that are physically different from each other, control information for: setting, as beam pattern combination candidates to be used in real communication, some combinations among combinations between first beam patterns usable by the first transceiver and second beam patterns usable by the second transceiver; setting indices with respect to the respective combination candidates; performing, in parallel, communication by the first transceiver and by the second transceiver; and specifying a combination of beam patterns to be used by using the indices. The base station device performs communication, in which the terminal device has used the combination between the first beam pattern and the second beam pattern specified by means of the indices, between the base station and said terminal device.
