Abstract: A wireless transmit/receive unit (WTRU) and a Node B, respectively, perform joint randomness not shared by others (JRNSO) measurement to generate JRNSO bits based on a channel estimate between the WTRU and the Node B. The WTRU and the Node B then perform a reconciliation procedure to generate a common JRNSO bits. The Node B sends the common JRNSO bits to a serving network. The WTRU and the SN secure a session key (such as an integrity key, a cipher key and an anonymity key), using the common JRNSO bits. The JRNSO measurements are performed on an on-going basis, and the session key is updated using a new set of common JRNSO bits. The JRNSO bits may be expanded by using a pseudorandom number generator (PNG) or a windowing technique. A handover may be intentionally induced to increase the JRNSO bits generation rate.

Abstract: A client station in a wireless local area network (WLAN) communication system includes a beam commutation algorithm and a smart antenna responsive to the beam commutation algorithm for selecting one of a plurality of directional antenna beams. The smart antenna is configured as a virtual omni-directional antenna by using a commutation of switched directional antenna beams. A switched directional antenna system that performs a commutation sequencing can be blind to environmental conditions and changes.

Abstract: A smart antenna steering algorithm performs a self-monitored re-scan during a sustained use period after having selected a preferred antenna beam. During a sustained use period, a re-scan of the other antenna beams is not performed. The steering algorithm periodically monitors a quality metric of the ongoing radio link provided by the preferred antenna beam. The quality metric is based upon a signal quality metric and a link quality metric. If the quality metric drops below certain thresholds during the sustained use period, the steering algorithm either swaps the preferred antenna beam with an alternate antenna beam or initiates a re-scan of the available antenna beams for selecting a new preferred antenna beam.

Abstract: A communications device with a switched beam antenna operates in a wireless local area network (WLAN) that includes a plurality of transmitters. The switched beam antenna generates a plurality of antenna beams. A method for operating the communications device includes receiving signals from the plurality of transmitters operating within the WLAN, identifying the received signals comprising medium access control (MAC) information, and determining a quality metric for each received signal comprising MAC information. A transmitter is selected based on the quality metrics. The antenna beams are scanned for receiving from the selected transmitter the signals comprising MAC information. A quality metric associated with each scanned antenna beam is determined. One of the scanned antenna beams is then selected for communicating with the selected transmitter based on the quality metrics.

Abstract: 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.

Abstract translation: 智能天线导向算法响应于由客户站内的媒体访问控制（MAC）层监视的不同功能而工作。 一个功能是当MAC层指示客户端站已经处于省电模式时。 作为响应，天线算法存储当前选择的天线的索引。 另一个功能是当MAC层指示客户端站未被同步，与接入点关联和认证时。 作为响应，该算法选择全向天线波束作为默认天线波束。 另一个功能是当MAC层向天线导向算法提供信标周期同步信息时，算法可以更新自己的定时器。

Abstract: Methods and apparatus are disclosed to provide protection against Unsolicited Communication (UC) in a network, such as, without limitation, an Internet Protocol (IP) Multimedia Subsystem (IMS). A communication may originate from a sending device and may be intended for delivery to a receiving device. A network may determine authentication information associated with the sending device. The network may send the authentication information to a receiving entity to evaluate if the communication is unsolicited using the authentication information. If the communication is determined to be acceptable, a connection associated with the communication may be allowed.
