Method For Reducing Time Of Flight Interference In A Wireless Communication Network

View page
US Patent:
8068786, Nov 29, 2011
Filed:
Feb 18, 2009
Appl. No.:
12/388391
Inventors:
Hemanth Balaji Pawar - Herndon VA, US
Swati Tiwari - Austin TX, US
Krishna D. Sitaram - Chantilly VA, US
Jong-hak Jung - Herndon VA, US
Esmail Hejazi Dinan - Herndon VA, US
Assignee:
Clear Wireless LLC - Kirkland WA
International Classification:
H04B 1/00
US Classification:
455 631
Abstract:
A method for identifying time of flight interference in a wireless communication network is provided. The method includes detecting interference during a first uplink sub-frame at an interference destination base station, and transmitting a time of flight interference source detection request to a gateway, where the time of flight interference source detection request comprises a time of flight interference period. The method also includes determining one or more base stations in the vicinity of the interference destination base station, where the one or more base stations in the vicinity of the interference destination base station operate at a same frequency as the interference destination base station. The method further includes instructing the one or more base stations in the vicinity of the interference destination base station to re-transmit a preamble at least once in a downlink sub-frame, decoding a first preamble of a first interference source base station at the interference destination base station during a second uplink sub-frame, and identifying the first interference source base station based on the first preamble.

Mobile Communication Device Initiated Hand-Off Based On Air Interface Metrics

View page
US Patent:
8068838, Nov 29, 2011
Filed:
Aug 19, 2008
Appl. No.:
12/193926
Inventors:
Esmail Hejazi Dinan - Herndon VA, US
Jong-hak Jung - Herndon VA, US
Swati Tiwari - Fairfax VA, US
Hemanth Balaji Pawar - Herndon VA, US
Krishna D. Sitaram - Chantilly VA, US
Assignee:
Clear Wireless LLC - Kirkland WA
International Classification:
H04W 36/00
H04W 24/00
H04W 4/00
H04M 1/00
US Classification:
455436, 4555531, 4555521, 4554566, 370331, 370338
Abstract:
A mobile communication device wirelessly transfers user communications to a first wireless base station. The mobile communication device determines a first metric based on a load indicator for the first base station. The mobile communication device identifies a second wireless base station and determines a second metric based on a load indicator for the second base station. If the second metric is superior to the first metric, the mobile communication device determines if the second base station has sufficient performance characteristics for communication with the device. If the performance is sufficient, the mobile communication device initiates a hand-off from the first base station to the second base station. The mobile communication device may use additional factors to determine the first and second metrics.

Mobile Communication Device Initiated Hand-Off Based On Wireless Base Station Priority

View page
US Patent:
8121090, Feb 21, 2012
Filed:
Jul 29, 2008
Appl. No.:
12/181924
Inventors:
Esmail Hejazi Dinan - Herndon VA, US
Jong-hak Jung - Herndon VA, US
Swati Tiwari - Fairfax VA, US
Hemanth Balaji Pawar - Herndon VA, US
Krishna D. Sitaram - Chantilly VA, US
Assignee:
Clearwire IP Holdings LLC - Bellevue WA
International Classification:
H04W 36/04
US Classification:
370331, 455437, 455444
Abstract:
A mobile communication device wirelessly transfers user communications to a first wireless base station. The mobile communication device identifies a second wireless base station that has sufficient performance characteristics for wireless communication with the mobile communication device and that has a higher communication priority than the first wireless base station. In response, the mobile communication device initiates a hand-off from the first wireless base station to the second wireless base station. In response to the hand-off, the mobile communication device stops the wireless transfer of the user communications to the first wireless base station and wirelessly transfers additional user communications to the second wireless base station.

Dynamic Transmission Of Dcd And Ucd Messages In A Wimax Network

US Patent:
8130728, Mar 6, 2012
Filed:
Sep 23, 2008
Appl. No.:
12/235948
Inventors:
Esmail Dinan - Herndon VA, US
Swati Tiwari - Fairfax VA, US
Hemanth Balaji Pawar - Herndon VA, US
Krishna Sitaram - Chantilly VA, US
Jong-hak Jung - Herndon VA, US
Assignee:
Clearwire IP Holdings LLC - Bellevue WA
International Classification:
H04B 7/216
US Classification:
370335, 370229, 455500
Abstract:
Disclosed herein is a method and system for transmitting coding descriptor information that can be implemented in a WiMAX communication network. The method comprises (a) dividing the coding descriptor information into a first set and a second set of coding descriptor information, wherein the first set comprises coding descriptor information that is used in initial ranging; (b) determining a repetition frequency at which to periodically transmit the first set of coding descriptor information; (c) periodically transmitting the first set of coding descriptor information at the determined repetition frequency; (d) detecting a triggering event, wherein the triggering event comprises receipt of a message from an access terminal; and (e) in response to detecting the triggering event, transmitting the second set of coding descriptor information.

US Patent:
8185146, May 22, 2012
Filed:
Jul 24, 2009
Appl. No.:
12/509130
Inventors:
Esmail Hejazi Dinan - Herndon VA, US
Krishna D. Sitaram - Chantilly VA, US
Jong-hak Jung - Herndon VA, US
Swati Tiwari - Austin TX, US
Hemanth Balaji Pawar - Herndon VA, US
Assignee:
Clearwire IP Holdings LLC - Bellevue WA
International Classification:
H04B 7/00
US Classification:
455522, 455 6711, 455 68, 455 69
Abstract:
A first wireless device associated with a first profile is communicated with using a first transmitted power. A second wireless device associated with a second profile is communicated with using a second transmitted power. A third transmitted power is determined. The third transmitted power is associated with the first wireless device receiving data using a target modulation and coding scheme. A maximum transmitted power is determined to be exceeded if the third transmitted power is used to communicate with the first wireless device. The second wireless device is communicated with using a fourth transmitted power. The fourth transmitted power allows the third transmitted power to be used to communicate with the first wireless device without exceeding the maximum transmitted power.

System And Method For Multimode Device Handover

US Patent:
8285291, Oct 9, 2012
Filed:
Feb 2, 2010
Appl. No.:
12/698384
Inventors:
Esmail H. Dinan - Herndon VA, US
Hemanth Balaji Pawar - Herndon VA, US
Swati Tiwari - Austin TX, US
Krishna Sitaram - Chantilly VA, US
Jong-Hak Jung - Herndon VA, US
Assignee:
Clearwire IP Holdings LLC - Bellevue WA
International Classification:
H04W 36/00
US Classification:
455443, 455436, 4554522, 455448, 455437, 455438, 455439, 455440, 455453, 370331
Abstract:
Systems and methods of operating multimode 3G/4G communications devices in an overlapping 3G/4G coverage area (e. g. , WiMAX or LTE/CDMA-EvDO) include determining a loading condition of the 3G and 4G base stations. If the 3G and 4G base stations are lightly loaded, one or more 4G Channel Quality Indicators (CQI) are compared with one or more corresponding 3G Data Rate Control (DRC) indices to determine which of the 3G and 4G networks allows a higher data throughput. The dual mode communications device is handed off to a 4G base station associated with the 4G coverage if the 4G network allows the higher data throughput; otherwise, the dual mode communications device is handed off to a 3G base station. User priorities, application categories, and/or MIMO and diversity modes may be used to determine handoff if the base stations are more than lightly loaded.
