DATA TRANSMISSION METHOD, BASE STATION AND USER TRANSCEIVER

摘要

A multicarrier data transmission method and a base station (200) are provided. The base station comprises an antenna arrangement (204 to 208) configured to form multiple antenna beams, and a first controller (800) configured to divide subcarriers of the multicarrier transmission into more than one subcarrier group and allocate each subcar-rier group to an antenna beam, and a second controller (238) configured to control the antenna beams formed by the antenna arrangement during transmission to sweep constantly over a given area at a constant mean beam specific angular velocity.
