Method and apparatus for cooperative wireless communications

A method for use in a wireless transmit/receive unit (WTRU), the method comprising:

• transmitting channel state information (CSI) or beam-forming information to a plurality of network nodes;
• and
• receiving a beam-formed signal that includes data from each of the plurality of network nodes in response to the transmitted CSI or beam-forming information, wherein the same data is received from each of the plurality of network nodes.

A network node comprising:

• circuitry configured to receive channel state information (CSI) or beam-forming information for a plurality of network nodes from a wireless/transmit receive unit (WTRU);
• and
• circuitry configured to transmit a beam-formed signal that includes data to the WTRU substantially simultaneously with a beam-formed signal from another network node, in response to the transmitted CSI or beam-forming information, wherein the same data is transmitted in each of the beam-formed signals.
