摘要： An adaptive antenna base station apparatus comprises an array antenna including N (N being a natural number) antenna elements; N reception sections for respectively performing orthogonal detection of high-frequency signals, respectively received by the antenna elements, after frequency conversion; N×M despreading sections for performing despreading operations, corresponding to delay times of M (M being a natural number) path components included in output signals of the reception sections; M correlation computing sections for performing correlations among the antenna elements for each path; a correlation combining section for combining output signals of the correlation computing sections; and a DOA estimating section for estimating a direction of arrival (DOA) by using an output of the correlation combining section. This can ensure collective estimation of DOAs of M path components, thereby reducing the amount of computation of estimating the DOAs for plural paths and the cost for the apparatus.

摘要： Reliability of beam selection by pre-coding is improved. A user terminal 52 selects an optimum beam (beam number ‘b’) in the next frame (t+1) based on the channel estimation value of a received pilot signal and transmits a difference value D (=b−a) between a beam number ‘a’ at the current transmission notified by a radio base station 51 and the selected beam number ‘b’ selected to be transmitted at the next transmission to the radio base station 51 as a feedback signal. The radio base station 51 previously stores the beam number ‘a’ notified at the previous transmission and combines the beam number based on the difference value D received as the received feedback signal and the previously notified beam number ‘a’ to restore the beam number ‘b’ desired by the user terminal 52. Pre-coding processing adapted to the beam number ‘b’ is performed and transmission to the user terminal 52 is executed in a state in which a beam of the appropriate beam number ‘b’ is formed.

摘要： When power scaling is applied to multi-user MIMO, a reduction in transmission rate is suppressed and transmission efficiency is improved. When signals are transmitted through spatial multiplexing from a wireless base station 11 to a plurality of pieces of user equipment 12 and 13, notification of a transmission parameter (MCS) of the distant user equipment (UE-B) 13 is provided as control information to the adjacent user equipment (UE-A) 12. The user equipment 12 calculates, based on the received control information, a reception quality (CQI) after cancellation of a signal serving as an interference signal and destined for the other user equipment 13, and feeds back the calculated result to the wireless base station 11. Based on this feedback, the wireless base station 11 sets a transmission parameter (MCS) of each piece of the user equipment 12 and 13 using the CQI after the cancellation, and transmits signals intended for respective users through spatial multiplexing after performing power distribution between the users by power scaling.
