摘要： In a receive node (230) of a wireless network (100), an iterative multi- user multi-stage interference cancellation receiver (400, 800, 1100) is used. After each stage of interference cancellation, interference characteristics change. An adaptive finger placement strategy is used in which after each stage of interference cancellation, finger delays and combining weights of the receiver (400, 800, 1100) are adapted to reflect the changed interference characteristics.

摘要： The present invention is designed to reduce the decrease of spectral efficiency even when repetitious transmission is applied to communication by user terminals, in which the band to use is limited to a partial narrow band in a system band. According to one aspect of the present invention, a user terminal, in which the band to use is limited to partial narrow bands in a system band, has a receiving section that receives information related to spreading codes, a generation section that generates uplink signals, and a transmission section that repeats transmitting uplink signals in a plurality of subframes, and the generation section applies a predetermined spreading code to an uplink signal that is transmitted in part or all of the plurality of subframes, based on the information related to spreading codes.
