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: A technique is applied to increase secret bit generation rate for a wireless communication. A wireless transmit/receive unit (WTRU) measures channel impulse responses (CIRs) on downlink and generates secret bits based on the CIRs. Each of the network entities also measures a CIR on uplink between itself and the WTRU. On the network side, the network entities forward the CIRs on uplink to an aggregation controller, which generates secret bits based on the uplink CIRs. Alternatively, in a cooperative network, a cooperating node may measure CIRs on channels with a source node and a destination node and generate secret bits. The cooperating node then sends the secret bits to the destination node so that the secret bits are used for communication between the source and destination nodes. The secret bits are further characterized by a joint randomness not shared with others (JRNSO). The aggregation controller, such as radio network controller (RNC), intentionally induces a hard or soft handover of the WTRU to each of the network entities to increase the JRNSO bit generation rate.

Abstract translation: 应用一种技术来增加无线通信的秘密比特生成率。 无线发射/接收单元（WTRU）在下行链路上测量信道脉冲响应（CIR），并且基于CIR产生秘密比特。 每个网络实体还测量在其与WTRU之间的上行链路上的CIR。 在网络侧，网络实体将上行链路的CIR转发到聚合控制器，该聚合控制器根据上行链路CIR产生秘密比特。 或者，在协作网络中，协作节点可以测量具有源节点和目的地节点的信道上的CIR，并生成秘密比特。 合作节点然后将秘密位发送到目的地节点，使得秘密位用于源节点和目的节点之间的通信。 秘密位的进一步特点是与其他人（JRNSO）不共享的联合随机性。 诸如无线电网络控制器（RNC）之类的聚合控制器有意地引导WTRU到每个网络实体的硬切换或软切换，以增加JRNSO比特生成速率。

Abstract: The present invention relates to secret key generation and authentication methods that are based on joint randomness not shared by others (JRNSO), in which unique channel response between two communication terminals generates a secret key. Multiple network access points use a unique physical location of a receiving station to increase user data security. High data rate communication data is encrypted by generating a random key and a pseudo-random bit stream. A configurable interleaving is achieved by introduction of JRNSO bits to an encoder used for error-correction codes. Databases of user data are also protected by JRNSO-based key mechanisms. Additional random qualities are induced on the joint channel using MIMO eigen-beamforming, antenna array deflection, polarization selection, pattern deformation, and path selection by beamforming or time correlation. Gesturing induces randomness according to uniquely random patterns of a human user's arm movements inflected to the user device.
