Title:
COMMUNICATION DEVICE AND COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/161982
Kind Code:
A1
Abstract:
A wireless base station 100 comprises a plurality of sub-arrays 310 and a control unit 270 that determines a search beam for each of the plurality of sub-arrays 310 using a determination order that corresponds to a condition. The control unit 270 determines a search beam for each of the plurality of sub-arrays 310A, 310B, 310C in order from outside to inside on the basis of the arrangement of the sub-arrays 310A, 310B, 310C. The control unit 270 determines a search beam for each of the plurality of sub-arrays in an order that corresponds to the magnitude of the reception power of the sub-arrays.
