20 Claims

1. A wireless transmit/receive unit (WTRU) configured for multi-user multiple-input multiple-output (MU-MIMO) communications, the WTRU comprising:

a processor; and

transmitter circuitry configured to transmit a setup frame to a group of WTRUs comprising at least a first WTRU and a second WTRU, wherein the setup frame indicates a first transmission configuration for MU-MIMO transmissions from the WTRU to the first WTRU and a second transmission configuration for MU-MIMO transmissions from the WTRU to the second WTRU;

the transmitter circuitry configured to transmit first MU-MIMO transmissions to the first WTRU based on the indication of the first transmission configuration and second MU-MIMO transmissions to the second WTRU based on the indication of the second transmission configuration.
