BASE STATION DEVICE, USER DEVICE, AND COMMUNICATION CONTROL METHOD

摘要

A user device includes a plurality of antennas and transmits a reference signal by an upstream link by switching the antennas. The antennas are correlated to sub frames transmitted by the upstream link. A base station device in a radio communication system in which transmission diversity is applied to the upstream link includes: reception level input means which stores a reception level of the reference signal which has been measured for each of the antennas of each of user devices; and a scheduler which performs scheduling for deciding a user device to be allocated to a sub frame correlated to the antenna according to the reception level of the transmitted reference signal for each of antennas of each of user devices stored in reception level storage means.
