Document Type and Number:
WIPO Patent Application WO/2021/070508
Kind Code:
A1
Abstract:
This base station is provided with: a control circuit which determines a disposition method for a downlink control channel signal in at least one among a first period before a timing based on a carrier sense and a second period after the timing based on the carrier sense on the basis of information about at least one among the number of times a downlink control channel signal is blind-decoded and the number of resources for channel estimation; and a transmission circuit which transmits the downlink control channel signal on the basis of the determined disposition method.
