US Patent:

6920598, Jul 19, 2005

Filed:

May 21, 2001

Appl. No.:

09/861740

Inventors:

Wen-Yi Kuo - Morganville NJ, US
Gang Li - Bridgewater NJ, US
Martin Meyers - Montclair NJ, US

Assignee:

Lucent Technologies Inc. - Murray Hill NJ

International Classification:

G08C025/02

US Classification:

714748, 714750

Abstract:

In a system of communication, a sending node sends a message to a receiving node, which NAKs unsuccessful transmissions. The sending node screens the NAKs to determine if they were sent before the receiver could receive previous transmissions of the same data NAKed. One screening technique is based on an estimated round trip time of a message. Another alternate technique looks a flag in the NAK that synchronizes the sender and the receiver.

International Classification:

H04Q 7/20

US Classification:

4554323, 455437, 455567

Abstract:

A mobile wireless terminal is configured to provide an audible alert to the user in the event of its receipt, while the terminal is on a call, of an indication of an imminent or directed handoff to a carrier or network which would charge the user for roaming. The call is automatically terminated or released within a predetermined time period after the audible alert unless the user performs an act of assent, such as pressing a predetermined key, or speaking a predetermined command, before the expiration of the time period.

Appl. No.:

10/665611

Inventors:

Gang Li - Bridgewater NJ, US
Ming Lu - Hillsborough NJ, US
Martin H. Meyers - Montclair NJ, US

Assignee:

Lucent Technologies Inc. - Murray Hill NJ

International Classification:

H04L 1/00

US Classification:

3702301, 370229, 370230, 370235

Abstract:

The invention operates to determine a measure of one or more input data parameters, such as input data rate and input data buffer fill at the beginning of a data burst. The invention then proceeds to the selection of an operating data rate for the data burst as a function of the input data parameter measures. In a further step, the invention proceeds to a selection of a duration for the data burst as a function of the selected operating data rate and an end-of-burst data residue parameter.

Assignee:

Alcatel Lucent - Paris

International Classification:

H04B 7/216

US Classification:

370342, 455522

Abstract:

In an H-ARQ system, when the AN is receiving packet data traffic on the RL from an AT and is generating ACKs and NAKs according to the ability of the AN to properly decode such data, the AN gates-off a DRCLock bit within in a sub-packet duration in which an ACK is transmitted on the FL MAC channel. When it receives an ACK, the AT ignores the non-transmitted DRCLock bit in a current sub-packet duration, and assumes that the DRC channel is “good”. When the AN sends a NAK to the AT, it also sends the DRCLock bit. When the AT receives a NAK in a sub-packet duration, it reads and processes whatever DRCLock bit is received during that sub-packet duration. When no data traffic is transmitted on the RL traffic channel, corresponding DRCLock bits are not gated-off by the AN and are transmitted to the AT. The AT then processes the received DRCLock bits. In an alternative embodiment, transmission of DRCLock is totally eliminated.

Assignee:

Siemens Corporation - Iselin NJ

International Classification:

G06K 9/46

US Classification:

382203, 382285

Abstract:

A method for reconstructing three-dimensional, plural views of images from two dimensional image data. The method includes: obtaining two-dimensional, stereo digital data from images of an object; processing the digital data to generate an initial three-dimensional candidate of the object, such process using projective geometric constraints imposed on edge points of the object; refining the initial candidate comprising examining spatial coherency of neighboring edge points along a surface of the candidate.

Abstract:

There is provided a system and method and apparatus for selecting data rates in a wireless communication system. More specifically, there is provided a method comprising selecting one of a plurality of data rate control values for a transmission based on an adjustable relationship between the selected data rate control value and a transmission error margin related to the selected data rate control value.

Appl. No.:

Ming Lu - Hillsborough NJ, US
Jialin Zou - Randolph NJ, US

International Classification:

H04Q 7/00

US Classification:

370329

Abstract:

In an H-ARQ system, when transmission on the FL MAC channel of DRCLock or CQILock bits is eliminated, other feedback information carried by the FL MAC channel is used as an RL quality indication for determining at least in part when to make a serving sector switch from a current serving sector to a non-serving sector in its active set. In particular, when data traffic is present, the ACKs/NAKs fed back to the AT on the FL MAC channel are used at least in part in determining when to make such a serving sector switch. In systems operating in accordance with CDMA2000 EVDO RevA/RevB standards, for example, this information is used in conjunction with quality measurements on the FL in determining when to make a serving sector switch. In future systems operating in accordance with CDMA2000 EVDO RevC standards currently under development in which the RL can be switched independently of the FL, this information is directly used to determine when to make an RL serving sector switch.

Gang Li - Bridgewater NJ, US
Ming Lu - Hillsborough NJ, US
Martin H. Meyers - Montclair NJ, US

International Classification:

H04J 3/24

US Classification:

370312

Abstract:

A disclosed method of communicating includes using a group identifier within a multi-user packet (MUP) to indicate at least one packet within the MUP is intended for a plurality of members of a group corresponding to the group identifier. In a disclosed example, the group identifier comprises a group MAC identifier that is included in a header of the MUP. Mobile stations receiving the MUP process the MUP to determine whether any individual user identifier or any group MAC identifier within the MUP indicates that an associated packet is intended for that mobile station. If so, the mobile station proceeds to process the associated packet or packets from within the MUP.
