Abstract
(EN)

PROBLEM TO BE SOLVED: To provide an information communication method and apparatus for enabling base stations to inform each other about an occupation situation of an unlicensed carrier.

SOLUTION: A sending end uses a physical control channel PDCCH, an enhanced physical control channel ePDCCH, or downlink control information (DCI) transmitted in agreed resources to describe the information about time when unlicensed carriers are occupied S102; and sends the DCI information through licensed carriers or the unlicensed carriers S104; The information about time includes: a starting subframe occupying an unlicensed carrier and the number of subframes that are continuously occupied starting from the starting subframe.
