Appl. No.:

10/725095

Assignee:

Lucent Technologies Inc. - Murray Hill NJ

International Classification:

H03K 9/00
H03D 1/04

US Classification:

375316, 375346, 375147

Abstract:

The disclosed embodiments relate to a communication system and method. The system may comprise a pre-whitening device that applies pre-whitening data to a received signal from an antenna array to produce a pre-whitened signal, at least one detector that is adapted to recognize a pattern corresponding to a request for access in the pre-whitened signal and compute correlation data corresponding to the pattern, and a threshold detector that determines whether the correlation data exceeds a threshold and indicates that an acknowledgement signal should be transmitted if the threshold is exceeded. The method may comprise the acts of creating a pre-whitened signal by applying pre-whitening data to a received signal, detecting a pattern that corresponds to a request for access in the pre-whitened signal, computing correlation data corresponding to the pattern, determining whether the correlation data exceeds a threshold, and indicating that an acknowledgement signal should be transmitted if the threshold is exceeded.

International Classification:

H04Q 7/00

US Classification:

370334, 370337, 370350, 4554522, 455439

Abstract:

A wireless communication system () includes using multiple antennas () for simultaneous transmissions to multiple mobile stations (). A distributed multiple antenna scheduling (DMAS) technique includes selecting a plurality of mobile stations for at least receiving simultaneous transmissions on at least one selected subcarrier from within a carrier bandwidth having orthogonal frequency division multiplexing (OFDM). In a disclosed example, a plurality of mobile stations are selected for each subcarrier within the carrier bandwidth. A disclosed example includes grouping subcarriers together into subsets to reduce computation complexity for determining which mobile stations to select for the simultaneous transmission.

International Classification:

H04M 15/00

US Classification:

3791142, 37911415

Abstract:

A point-of-sale electronic distribution system for distributing an access code (e. g. , a personal identification number (PIN)) is provided. The system allows retailers/distributors to purchase access codes for use with pre-paid products using conventional telephones and without requiring the use of a dedicated terminal or personal computer at the point-of-sale. A telephone call relating to a request for an access code is received at a central server. An access code is obtained from a database of access codes and transmitted to the caller by telephone, facsimile, or e-mail. Reports relating to a pre-paid calling card account can be requested during the telephone call.

International Classification:

H04W 4/02

US Classification:

4554561

Abstract:

Methods and apparatuses are provided for user equipment positioning in networks. An example method includes computing a location of a user equipment (UE). The computing includes joint scheduling of UL subframes and receiving a Up Link Positioning Reference Signal (UL-PRS). The computing is performed by a network equipment that serves at least one cell site. The UL-PRS is received in a known subframe. The computing may also include estimating an arrival time the UL-PRS from the UE for a plurality of cell sites. In another embodiment, the computing includes determining a one-way delay between
