Embodiments of the present invention provide an apparatus capable of filling space-time channels in Spatial-Division Multiple-Access (SDMA) in a Medium Access Control (MAC) protocol, comprising, a base station operable in a wireless network and adapted for uplink and downlink multi-user and multi antenna operation, the base station including a MAC scheduler to schedule transmissions using packet scheduling in the wireless network, and wherein the MAC scheduler schedules variable length packets for transmission using packet scheduling in the wireless network based on transmission times to transmit on each of M spatial channels to mobile stations operable in the wireless network by filling the M spatial channels using data packets buffered for the mobile stations operable to communicate with the base station.
