INFORMATION PROCESSING APPARATUS, NETWORK NODE, AND INFORMATION PROCESSING METHOD

摘要

Provided are an information processing apparatus, a network node and an information processing method. The information processing apparatus can comprise an inverse fast Fourier transform (IFFT) module, a pre-coding module and a determination module, wherein the IFFT module is used for respectively performing IFFT processing on N frequency domain data flows so as to acquire N time domain data flows, N being a positive integer; the pre-coding module is used for performing pre-coding processing on the N time domain data flows so as to acquire a pre-coding processing result; and the determination module is used for determining an orthogonal frequency division multiplexing (OFDM) symbol which is required to be sent over each antenna of M antennas according to the pre-coding processing result, so that an information transmission apparatus sends the OFDM symbol which is required to be sent over the each antenna via the each antenna of M antennas, M being a positive integer greater than N. The embodiments of the present invention can reduce hardware resource consumption or improve the operating efficiency of a system.
