Advanced antenna technologies and algorithms that have been developed during the last decades are currently being integrated into modern wireless systems. As one of the first standards the wireless metropolitan area network IEEE 802.16 provides means to support smart antenna techniques. After an introduction to the medium access control and the physical layer this paper outlines the support of space division multiple access (SDMA) techniques by IEEE 802.16. It shows the influence of intra-cell interference generated by concurrent SDMA transmissions. Finally, the authors present two SDMA-specific scheduling algorithms that are able to cope with the additional interference.
