Abstract:
An authentication system includes a first authentication key associated with a first device, the first authentication key having a corresponding authentication level, a second authentication key associated with a second device, the second authentication key having a corresponding authentication level, and an enhanced authentication key generated when the first and second authentication keys are combined, the enhanced authentication key having an authentication level that represents a higher authentication level than the authentication level of the first authentication key and the authentication level of the second authentication key.
Abstract:
Embodiments disclosed herein relate to methods and systems for providing improved position-location (e.g., time-of-arrival) measurement and enhanced position location in wireless communication systems. In an embodiment, an access point may replace information (e.g., data) transmission by a “known” transmission (or “reference transmission”) at a predetermined time known to access terminals in the corresponding sectors. The access terminals may use the received reference transmission to perform a position-location measurement, and report back the measured information. The access point may also send a reference transmission on demand, e.g., in response to a request from an access terminal in need for a location-based service.
Abstract:
Certain aspects of the present disclosure relate to adapting transmitter configuration for efficient concurrent primary user detection through adaptive self-interference cancellation. A wireless transmitting device may schedule a transmission in a shared spectrum. The device may scan at least a portion of the shared spectrum during the transmission to receive a signal. Interference caused by the transmission may he cancelled from the received signal using self-interference cancellation circuitry. The device may determine whether the received signal indicates usage by a primary user of the shared spectrum. In an aspect, the transmission may be a SISO transmission. In another aspect, carrier aggregation may be used for the transmission and a potential carrier may be subject to primary user detection. The device may determine a self-interference cancellation complexity for a combination of carriers including the potential carrier, and may select one or more carriers for aggregation based on the self-interference cancellation complexity.
Abstract:
Embodiments disclosed herein relate to methods and systems for providing improved position location (e.g., time-of-arrival) measurement and enhanced position location in wireless communication systems. In an example method, an access terminal may receive a reference signal in a time slot, the reference signal comprising a sequence of symbols known to a receiver before being received, and may determine, based at least in part on the reference signal, a position location of the access terminal.

Abstract:
A method, an apparatus, and a computer program product are provided in connection with facilitating hybrid unicast/broadcast service distribution. In one example, a communications device is equipped to provide a parity portion of titles in a channel of a service to a plurality of UEs at a first time, receive, from a UE at a second time, a request to access a title of the one or more titles, and provide an enablement item, to the requesting UE, which is a portion of the requested title that, when processed with the provided parity portion of the requested title, is sufficient to allow the requesting UE to decode and access to the requested title. In an aspect, the parity portion may be a parity portion of a fountain code encoded title, and the enablement item may be repair symbols of the fountain code encoded title.
Abstract:
A deployment and distribution model improves content delivery with a business incentive for placement of kiosks with one or more wireless access points in public locations so that portable media players (PMPs) can receive media content (e.g., audio, video, text, haptic content, etc.). In addition, coordination between subscribing users of PMPs, vendors who provide kiosks, and a network central controller of a content distribution system allow for prepositioning of video content at the kiosks through economically desirable low data rate communication links from the network (e.g., dial-up modem, DSL, etc.); coordinated queuing of downloads (e.g., partial downloads) between kiosk to PMP, peer-to-peer (P2P) downloading between PMPs, and uploads from PMP to kiosk; billing/crediting to correspond with such participation in the distribution; and changing priority/selection of prepositioning of content at kiosks to reflect a clientele profile.
Abstract:
A display device may include a display, an optical touch system proximate the display and a control system. The control system may be capable of receiving input for initiating a peer-to-peer data transfer and of performing an authentication process for the peer-to-peer data transfer. The authentication process may involve obtaining fingerprint images via the optical touch system. The display device may provide a prompt to position the display device proximate a second device, e.g., with the display adjacent to a display of the second device. The display may display data transfer parameters for the peer-to-peer data transfer. The optical touch system may receive a confirmation that the second device received the data transfer parameters. The peer-to-peer data transfer may be performed, at least in part, by an array of optical transceivers.
