摘要： Embodiments are provided for enabling a beamforming mechanism in WLAN OBSSs. In an embodiment, a first AP of the OBSSs decides to participate in coordinated beamforming for the OBSSs. The OBSSs comprise a plurality of APs and a plurality of STAs associated with the APs. The AP thus transmits, periodically, a coordinated beamforming (CB) announcement message indicating an ID of the first AP and an ID of each STA associated with the first AP. When a second AP of the OBSSs receives the message from the first AP, the second AP maintains the ID of the first AP and the ID of each STA associated with the first AP in an entry of a CB table. When the second AP stops receiving the message, the second AP removes, from the CB table, the entry of the IDs of the first AP and its associated STAs.

摘要： Fast mobile device authentication can be achieved during inter-domain handovers between administrative domains operating under a federated service agreement using pseudonym identifications (PID). Specifically, the mobile device may derive a PID when obtaining authentication in a first wireless network, and then use the PID to obtain fast authentication in a second wireless network. The PID may be generated during an Elliptic curve Diffie–Hellman (ECDH) authentication procedure using public keys associated with the mobile device and the first wireless network. The PID (or a derivative thereof) may then be provided to an authentication server in a second wireless network for validation. The PID may be validated by the second authentication server via online or offline validation procedures. The PID can also be used as an electronic coupon for accessing the second network.

摘要： Embodiments are provided to enable concurrent uplink transmissions from multiple Wi-Fi stations(STAs)to one or more access points(APs)using Interference Alignment(IA).In an embodiment,the STAs broadcast,to one or more APs, beamforming reports including channel estimation information for downlink. The one or more AP then performs channel estimation using the beamforming reports,and selects at least some of the STAs. The AP also computes beamforming information for IA of uplink transmissions between the selected STAs and sends,to the selected STAs,the beamforming information. The beamforming information is piggy-backed over downlink data packets to the selected STAs. Each selected STA then sends an uplink data frame concurrently with one or more other uplink data frames from one or more other selected STAs to the AP. The uplink data frames are configured for concurrent uplink transmissions according to the beamforming information for IA.

摘要： Methods and apparatuses for supporting outside the context of a basic service set (OCB) concurrent with infrastructure-based communications, including cellular communications or basic service set (BSS) communications, are described. OCB service information is transmitted by an infrastructure unit in an infrastructure-based communication. The OCB service information include a service identifier and channel information for each available OCB service. The infrastructure unit may then communicate with a terminal unit over an OCB communication link, to provide an OCB service to the terminal unit. The OCB service information may be communicated in an OCB operation information element (IE) including a service hash field and an operating class and channel field.
