Method and apparatus for medium access control in a wireless broadband system with multiuser MIMO/MISO technology comprising the steps of a transmitter (Tx) broadcasting a polling message () to all the users (Rx. . . Rx. . . RX) associated to said transmitter (Tx); the users answering with reply messages () during a time slot () randomly selected from a plurality of time slots in which a period of time dedicated to sending reply messages () is divided; the transmitter (Tx) performing a scheduling and transmission of data (); and scheduled users sending Acknowledgment messages ().
