摘要
System and methodologies are provided herein for multiuser scheduling in a multiple-input multiple-output (MIMO) communication system. Various aspects described herein facilitate full feedback scheduling, wherein multiuser scheduling is performed based on an antenna selection and signal quality feedback, such as signal-to-interference-plus-noise ratio (SINR) feedback, from respective users. Based on information received from respective users, independent information streams can be transmitted from respective transmit antennas to respective users with the highest signal quality. Receive antenna selection can also be employed to allow respective users to select a single receive antenna on which information is to be received. Additional aspects described herein facilitate quantized feedback scheduling, wherein scheduling is performed based on signal quality feedback that is quantized into a finite number of bits by respective users.
