Patent ID: 7688979

Claim:
A wireless transmit/receive unit (WTRU) including a transceiver, the transceiver comprising: a data processing module configured to provide user data streams to a medium access channel (MAC) module and channel state information to a smart antenna processor; a security processing module configured to generate security data and for providing security policy data; the medium access control (MAC) module configured to determine data transmission rates for the data streams and security data; and to allocate said data streams and security data to transmission channels for transmission; a dirty-paper-coding (DPC) module configured to encode the security data onto the user data streams; the smart antenna processor configured to generate and provide the pre-coding coefficients to the DPC module; and a plurality of antennas configured to transmit the security encoded data streams; wherein the security processing module further comprises a token generating sub-module configured to generate the security tokens and keys; wherein the smart antenna module is configured to use the channel state information and the security policy data to provide beam-steering, pre-equalization, and eigen-beam-steering functionality to the transceiver.
