Abstract: A method of establishing a direct wireless communication link between a first device and a second device (the first device being designated as a sender and the second device being designated as a receiver) comprises: a proximity authentication operation that comprises determining, based on signals received by the first and second devices over one or more RF channels from a plurality of wireless access points, that the first device is proximate the second device; following the proximity authentication operation, a key generation operation that comprises: generating a shared secret by performing randomness extraction on respective signals received at the first and second devices over a selected channel of the one or more RF channels; and establishing the direct wireless communication link using the shared secret.

Abstract: A method for authenticating a user in a session initiated on a computing device is disclosed herein.

Abstract: A method of communication comprising: determining whether a mobile station (MS) is within a collaborative zone with respect to a first base station (BS1), if the MS is within the collaborative zone (704): the BS1 transmitting one or more collaboration parameters to a network coordinator (706), the network coordinator determining one or more collaborative base stations depending on the collaboration parameters, the network coordinator transmitting control parameters to the BS1 and the one or more collaborative base stations (BS2) (708), and the BS1 transmits via wired backhaul the data to be transmitted to the MS and channel information between the MS and the BS1 in accordance with the control parameters to the BS2 (710), the BS1 and the BS2 collaboratively transmitting data to the MS in accordance with the control parameters (712). Also an integrated circuit, a mobile station, a base station and a network coordinator.
