20100146289, Jun 10, 2010

Filed:

Oct 29, 2009

Appl. No.:

12/608319

Inventors:

Theodoros Kamakaris - Jersey City NJ, US
Patrick White - Bernardsville NJ, US

International Classification:

H04L 9/32

US Classification:

713180, 380270, 380263

Abstract:

A method is provided for encryption/decryption for secure the privacy of the information flow between two communicating nodes, and authentication to establish the identity of the communicating nodes in digital communications systems. A common secret or encryption key is generated at the two nodal ends of the communication link without prior dissemination. The authenticity of the communicating entities are maintained over time based on unique non-idealities of the communicating nodes in conjunction with the propagation characteristics of a link between them.

International Classification:

H04W 24/10
H04W 76/14
H04W 72/08

Abstract:

This disclosure relates to techniques for coordinated channel state information reporting in a wireless communication system. A wireless device may establish a wireless link with a cellular base station. The wireless device may determine to coordinate channel state information reporting with another wireless device. Information may be exchanged with the other wireless device via a sidelink wireless link. The wireless device may provide channel state information to the cellular base station. The channel state information may be determined based at least in part on the information exchanged with the other wireless device via the sidelink wireless link.

International Classification:

H04B 1/00
H01Q 1/24

Abstract:

An electronic device may include wireless circuitry with a baseband processor, a transceiver, and an antenna. The antenna may be coupled to one or more antenna tuning elements for tuning the antenna over multiple communications (frequency) bands of interest. The baseband processor may be configured to simultaneously broadcast, over a digital interface, an aggregate message that includes control bits for adjusting multiple antenna tuning elements coupled to the digital interface. Adjusting multiple antenna tuning elements by issuing a single broadcast command can help optimize interface efficiency while maintaining compatibility with existing industry standards.

Inventors:

- Sunnyvale CA, US
Theodoros KAMAKARIS - San Jose CA, US

Assignee:

LITEPOINT CORPORATION - Sunnyvale CA

International Classification:

H04B 17/00

US Classification:

455 6714

Abstract:

A system and method for confirming radio frequency (RF) signal connectivity integrity with a device under test (DUT). An output RF signal is provided to a RF signal port and looped back for analysis along with an input RF signal, which includes a reflected signal component related to the output RF signal, from the RF signal port. By measuring magnitudes of combinations of the input and loopback RF signals, e.g., at multiple signal frequencies, it can be determined whether the RF signal port is properly terminated by the DUT.
