    摘要： A smart antenna steering algorithm operates in response to different functions monitored by the media access control (MAC) layer within a client station. One function is when the MAC layer indicates that the client station has been placed in a power savings mode. In response, the antenna algorithm stores an index of the currently selected antenna. Another function is when the MAC layer indicates that the client station has not been synchronized, associated and authenticated with an access point. In response, the algorithm selects an omni-directional antenna beam as the default antenna beam. Another function is when the MAC layer provides beacon period synchronization information to the antenna steering algorithm so that the algorithm can update its own timer.

    摘要： The present invention is related to a wireless transmit/receive unit (WTRU) for providing advanced security functions. The WTRU includes trusted platform module (TPM) for performing trusted computing operations; and a secure time component (STC) for providing a secure measurement of a current time. The STC and the TPM are integrated to provide accurate trusted time information to internal and external to the WTRD. The STC may be located on an expanded a subscriber identity module (SIM), on the WTRU platform, or two STCs may be used, one in each location. Similarly, the TPM may be located on an expanded SIM, on the WTRU platform, or two TPMs may be used, one in each location. Preferably, the STC will include a real time clock (RTC); a; a tamper detection and power failure unit; and a time report and sync controller.

    摘要： The present invention discloses several methods to strengthen the integrity of entities, messages, and processing related to content distribution as defined by the Open Mobile Alliance (OMA) Digital Rights Management (DRM). The methods use techniques related to the Trusted Computing Group (TCG) specifications. A first embodiment uses TCG techniques to verify platform and DRM software integrity or trustworthiness, both with and without modifications to the DRM rights object acquisition protocol (ROAP) and DRM content format specifications. A second embodiment uses TCG techniques to strengthen the integrity of ROAP messages, constituent information, and processing without changing the existing ROAP protocol. A third embodiment uses TCG techniques to strengthen the integrity of the ROAP messages, information, and processing with some changes to the existing ROAP protocol.

    a receiver configured to receive an association request frame that contains a first antenna capability information element that indicates a plurality of requested antenna capabilities of a second STA;
    a processor configured to determine whether the first station supports at least one of the plurality of requested antenna capabilities and adjust settings to use a common sub-set of antenna capabilities on a condition that the first station supports at least one of the plurality of requested antenna capabilities; and
    a transmitter configured to transmit an association response frame that contains a second antenna capability information element that indicates the common sub-set of antenna capabilities.
