         8 . The device of  claim 6 , wherein the wireless communication unit is to transmit group allocation information to the plurality of wireless communication devices assigned to the group, wherein the group allocation information includes a group address assigned to the group, and wherein the wireless communication unit is to transmit the scheduling frame having an address filed including the group address. 
     
     
         9 . The device of  claim 1 , wherein the scheduling frame comprises a power save multi-poll (PSMP) frame. 
     
     
         10 . The device of  claim 1 , wherein the wireless communication unit is to transmit the plurality of transmissions in the form of a space-division-multiple-access transmission. 
     
     
         11 . A method comprising:
 transmitting at least one scheduling frame including an indication of a downlink period allocated for simultaneous transmission from a wireless communication device to at least one group of a plurality of other wireless communication devices; and   simultaneously transmitting a plurality of different wireless communication transmissions from the wireless communication device to the group of other wireless communication devices during the downlink period.   
     
     
         12 . The method of  claim 11 , wherein the scheduling frame includes an indication of at least one uplink period allocated for transmissions from the group of wireless communication devices to the wireless communication unit, and wherein the method includes simultaneously receiving a plurality of different uplink transmissions from the plurality of wireless communication devices of the group during the uplink period. 
     
     
         13 . The method of  claim 11  including transmitting the scheduling frame having an address field including a group address assigned to the group. 
     
     
         14 . The method of  claim 11  including, prior to transmitting the scheduling frame, reserving a wireless communication medium for a duration period including at least a duration of the scheduling frame and the downlink period. 
     
     
         15 . The method of  claim 11  including assigning the plurality of wireless communication devices to the at least one group based on traffic-specification (TSPEC) information corresponding to the plurality of wireless communication devices. 
     
     
         16 . The method of  claim 11 , wherein the scheduling frame comprises a power save multi-poll (PSMP) frame.
