MOBILE COMMUNICATION DEVICE, BASE STATION DEVICE, WIRELESS CONTROL METHOD, AND MOBILE COMMUNICATION SYSTEM

摘要

A mobile communication device includes a plurality of antennas which transmits and receives a radio signal, and a baseband processor which selects a transmission antenna used for data signal transmission from the plurality of antennas based on an instruction from a base station device and transmits a data signal using the transmission antenna, wherein the baseband processor determines a timing when a reference signal is transmitted using a standby antenna not used for data signal transmission based on the likelihood of the transmission antenna being switched and transmits the reference signal based on the determined timing.
