MOBILE TERMINAL DEVICE, WIRELESS BASE STATION DEVICE, AND COMMUNICATION CONTROL METHOD |
摘要 |
<p>Provided are a mobile terminal apparatus, a radio base station apparatus and a communication method, capable of orthogonalizing uplink reference signals between plural antennas in MIMO transmission. The mobile terminal apparatus has a reference signal generator (11) for generating DM-RSs using ZC sequences and a cyclic shift section (13) for cyclically shifting the DM-RSs by unit of plural antenna ports (19) to orthogonalize the DM-RSs for the antenna ports (19) between the antenna ports (19), and the cyclically shifted DM-RSs are transmitted via the respective antenna ports (19) to a radio base station apparatus eNB in an uplink.</p> |
