Method And Apparatus For Interleaving For Information Transmission Or Storage Applications

View page
US Patent:
6687870, Feb 3, 2004
Filed:
Sep 23, 1999
Appl. No.:
09/406173
Inventors:
Jafar Mohseni - San Diego CA
Brian Butler - La Jolla CA
Deepu John - San Diego CA
Haitao Zhang - San Diego CA
Assignee:
Qualcomm, Incorporated - San Deigo CA
International Classification:
H03M 1300
US Classification:
714762, 711217
Abstract:
Interleavers are used in data transmission and storage applications to introduce diversity into a data stream, thereby making adjacent symbols more independent with respect to a transfer environment of variable quality. Conventional interleavers require storage in whole units of data blocks. This storage requirement complicates implementations for applications where available circuit area is limited and data rates and block sizes are large. A novel interleaver produces an interleaved data block using storage space that is only a fraction of the size of the input data block.

Power Saving By Limiting Use Of Advanced Signal Processing

View page
US Patent:
8521237, Aug 27, 2013
Filed:
Jan 19, 2011
Appl. No.:
13/009646
Inventors:
Jafar Mohseni - San Diego CA, US
Helena Deirdre O'Shea - San Diego CA, US
William Stancer - Reading, GB
Assignee:
QUALCOMM Incorporated - San Diego CA
International Classification:
H04B 1/38
US Classification:
455574, 4552772
Abstract:
Systems, methods, and devices are described for power saving techniques in mobile devices. A signal quality metric of a received wireless signal may be monitored. A determination is made when the signal quality metric exceeds a threshold quality level for a time period. A subset of the signal processing functionality may be de-activated responsive to the determination. There may be different thresholds depending on whether the mobile device is in idle or connected mode. There may also be different thresholds for various signal processing algorithms.

Reducing Idle Mode Power Consumption For Monitoring Neighboring Base Stations

View page
US Patent:
20110280144, Nov 17, 2011
Filed:
May 16, 2011
Appl. No.:
13/108864
Inventors:
Jafar Mohseni - San Diego CA, US
Philip J. Children - Reading, GB
Nigel Phillip Robinson - Ashington, GB
Nicholas J. Tebbit - Old Windsor, GB
Christopher J. Smith - Franham, GB
Helena Deirdre O'Shea - San Diego CA, US
Assignee:
QUALCOMM INCORPORATED - San Diego CA
International Classification:
H04W 52/02
H04W 24/00
US Classification:
370252
Abstract:
A method for reducing idle mode power consumption is disclosed. An idle mode is entered. A neighboring base station is selected. If the selected neighboring base station is assigned a high-frequency monitoring mode, a signal strength of the neighboring base station is measured. A low-frequency monitoring mode is assigned to the selected neighboring base station if the signal strength of the selected neighboring base station has been below a power threshold for longer than a time threshold. Other aspects, embodiments, and features are also claimed and described.

Apparatus And Methods Of Communicating Over Multiple Subscriptions

View page
US Patent:
20130210421, Aug 15, 2013
Filed:
Jul 27, 2012
Appl. No.:
13/559990
Inventors:
Jafar Mohseni - San Diego CA, US
Helena Deirdre O'Shea - San Diego CA, US
Nigel Phillip Robinson - Farnborough, GB
Chih-Ping Hsu - San Diego CA, US
Rajagopal Jeenagala - San Diego CA, US
Assignee:
QUALCOMM INCORPORATED - San Diego CA
International Classification:
H04W 24/00
US Classification:
455423
Abstract:
The described aspects include a user equipment (UE) apparatus and corresponding method of communicating with multiple networks using multiple subscriptions. The UE can establish a call in a first network related to a first subscription over a transceiver. During the call, the UE autonomously tunes the transceiver to a frequency of a second network related to a second subscription within a defined gap during the call. The UE can monitor one or more channels in the second network during the defined gap for one or more idle-mode signals.

Methods And Devices For Optimizing Cell Re Acquisitions

View page
US Patent:
20130322328, Dec 5, 2013
Filed:
Oct 19, 2012
Appl. No.:
13/656489
Inventors:
Farrukh Rashid - Farnborough, GB
Jafar Mohseni - San Diego CA, US
Zhong Fan - Farnborough, GB
Assignee:
Qualcomm Incorporated - San Diego CA
International Classification:
H04W 56/00
US Classification:
370328
Abstract:
Access terminals are adapted to employ timing information for a Synchronization Channel (SCH) associated with a neighboring base station during a re-acquisition procedure after such timing information has been determined to be inaccurate, or potentially inaccurate. For instance, an access terminal can obtain timing information for a Synchronization Channel (SCH) associated with a neighboring base station, such as by means of a combined acquisition procedure. The access terminal may subsequently determine that the obtained timing information is, or appears to be, no longer synchronized with the base station. In response to such a determination, the access terminal can employ the obtained timing information to time the opening of a receive window for re-acquiring the base station. Other aspects, embodiments, and features are also claimed and described.

Method And Apparatus For Buffering Data Transmission Between Producer And Consumer

View page
US Patent:
6516360, Feb 4, 2003
Filed:
Sep 23, 1999
Appl. No.:
09/406172
Inventors:
Jafar Mohseni - San Diego CA
Brian Butler - La Jolla CA
Deepu John - San Diego CA
Assignee:
Qualcomm Incorporated - San Diego CA
International Classification:
G06F 1300
US Classification:
710 52, 710 20, 710 33, 710 53, 710 54, 710 55, 710 56, 710 60, 711111, 711113
Abstract:
A need to store data between a producing stage and a consuming stage commonly arises in digital processing applications. However, factors such as fabrication process limitations and circuit area constraints may restrict the amount of available storage. A novel method and apparatus for data buffering are disclosed which use less data storage than would be required by double buffering techniques.
