摘要： This invention discloses a method and apparatus for scheduling radio resources among service flows for services supported in a MIMO-OFDM wireless communication system. Preferably a portion of radio resources for allocation is expressed as bandwidth or slots in different units. The method comprises a first stage and a second stage of scheduling. The first stage guarantees supporting minimum data rates for different services. The second stage aims to satisfy a requirement of not exceeding maximum data rates for different services as well as to optimize the spectrum efficiency. Each stage comprises: selecting a primary flow according to prioritization of service flows; allocating a portion of resources for the primary flow; selecting one or more secondary flows if there is resource remaining available, so as to optimize spectrum efficiency when transmitting with the primary flow in the same SDMA region; and allocating a portion of resources to each secondary flow.
