RADIO COMMUNICATION BASE STATION DEVICE, RADIO COMMUNICATION MOBILE STATION DEVICE, AND RADIO COMMUNICATION METHOD IN MULTI-CARRIER COMMUNICATION |
摘要 |
<p>There is provided a mobile station device capable of effectively performing interference suppression symbol synthesis while suppressing the lowering of the transfer rate when using the repetition technique in multi-carrier communication. In the mobile station device (100), when the interference level exceeds a threshold value, a switching control unit (110) controls a switch (109) to connect a P/S unit (106) to a weight multiplication unit (113) and controls a switch (111) to connect a channel estimation unit (108) to a weight calculation unit (112). The weight calculation unit (112) calculates an interference suppression weight based on MMSE from a pilot symbol and a channel estimation value. The weight multiplication unit (113) multiplies a data symbol by the interference suppression weight. A synthesis unit (114) synthesizes the data symbol multiplied by the interference suppression weight in repetition unit.</p> |
