Abstract Wireless last mile technology, e.g. IEEE 802.16a or ETSI HiperMAN, is becoming a challenging competitor to conventional wired last mile access systems like DSL and cable modems or even fiber-optic cables. High data rates, low delay values and even quality of service can be provided by such systems. Advanced antenna algorithms have been developed years ago, e.g. beamforming came up some decades ago, spatial multiplexing algorithms, e.g. BLAST, were developed in 1996 and space time coding was first published in 1998. Since then, their fundamentals have been investigated and their improvements regarding the wireless link capacity have been proved. But till today, advanced antenna algorithms of the physical layer and the modes of operation of medium access layers have not been integrated in modern wireless systems. This paper outlines the support of space division multiple access techniques by the wireless metropolitan area network IEEE 802.16a. The system can simultaneously transmit data to different stations in downlink direction, a parallel reception of data is not possible. A new concept is introduced that additionally enables a simultaneous data reception from several different subscriber stations. Another approach further enhances the system by introducing a new idea to control the medium access control frame. The build up of the frame is signaled to the different stations separately by means of private control elements. Thus, the frame can be designed individually for every single station and more flexibility and a higher capacity is introduced to the system.
