Abstract:
1. A wireless communication method for transmitting broadcast control channel information having a plurality of blocks to a receiving terminal existing in a coverage area of a first directional antenna of a base station by rotation of a beam transmitted from the first directional antenna, the wireless communication method comprising the steps of: calculating a transmission block number-related condition necessary for enabling the receiving terminal to receive all the blocks of the broadcast control channel information, based on the total number of the blocks of the broadcast control channel information and a transmission block number, the transmission block number indicating the number of blocks of the broadcast control channel information which are transmitted by the first directional antenna during a reception period, the reception period indicating an interval between the time points when the receiving terminal receives the broadcast control channel information; calculating a beam rotation angular velocity-related condition based on the transmission block number-related condition, a block unit time, and a coverage angle, the block unit time indicating a time period needed by the first directional antenna to transmit one block of the broadcast control channel information, the coverage angle indicating an angle between two boundary lines of the coverage area; and controlling the first directional antenna to rotate the beam at a rotation angular velocity decided based on the beam rotation angular velocity-related condition.
