摘要： Embodiments of the present invention provide an information processing apparatus, a network node, and an information processing method. The information processing apparatus may include an inverse fast Fourier transform IFFT module, a precoding module, and a determining module. The IFFT module is configured to separately perform IFFT processing on N frequency-domain data streams to acquire N time-domain data streams, where N is a positive integer. The precoding module is configured to perform precoding processing on the N time-domain data streams to acquire a precoding processing result. The determining module is configured to determine, according to the precoding processing result, an orthogonal frequency division multiplexing OFDM symbol that needs to be sent over each antenna of M antennas, so that an information transmission apparatus sends, by using each antenna of the M antennas, the OFDM symbol that needs to be sent over each antenna, where M is a positive integer greater than N. According to the embodiments of the present invention, hardware resource consumption can be reduced, or operating efficiency of a system can be improved.

摘要： Disclosed are a data transmission method and apparatus. The method includes: encoding a data stream of a first receive end by using a first encoding mode, to obtain a first encoded data stream (S101); encoding a data stream of a second receive end by using a second encoding mode, to obtain a second encoded data stream (S102); encoding the first encoded data stream and the second encoded data stream by using a third encoding mode, to obtain a to-be-sent data stream (S103); and sending the to-be-sent data stream to a corresponding receive end by using antennas (S104). Because in the foregoing method, the to-be-sent data stream is obtained by encoding the first encoded data stream and the second encoded data stream, the to-be-sent data stream may be sent by using a time-frequency resource, that is, more than two user equipments may be scheduled in a time-frequency resource, which effectively improves a resource utilization rate.
