Methods And Systems For Server Selection During Feedback Channel Impairment In Wireless Communications

View page
US Patent:
8406774, Mar 26, 2013
Filed:
Aug 16, 2006
Appl. No.:
11/506108
Inventors:
Mehmet Yavuz - San Diego CA, US
Sarut Vanichpun - San Diego CA, US
Yeliz Tokgoz - La Jolla CA, US
Matthew Stuart Grob - La Jolla CA, US
Peter John Black - San Diego CA, US
Assignee:
Qualcomm, Incorporated - San Diego CA
International Classification:
H04W 40/00
US Classification:
455445
Abstract:
Embodiments disclosed herein relate to methods and systems for server selection during feedback channel impairment in wireless communications. The feedback channel may be provided by a data rate control (DRC) channel, transmitted from an access terminal to an access network relating the selected serving sector (DRC cover) and the desired data rate (DRC rate) for transmission on forward link. During DRC cover erasure (e. g. , due to channel impairment), a data source control (DSC) channel may be used as complimentary information to assist the DRC erasure mapping decision at the access network.

Inventors:
Stephen W. Edge - Escondido CA, US
Peter John Black - San Diego CA, US
Qiang Wu - San Diego CA, US
Wanlun Zhao - San Diego CA, US
Yeliz Tokgoz - San Diego CA, US
Roberto Padovani - San Diego CA, US
Ayman Fawzy Naguib - Cupertino CA, US

International Classification:
H04W 24/00
US Classification:
4554561, 4554565
Abstract:
Briefly, in accordance with one embodiment, a method of transmitting signals is provided. Signal waveforms are transmitted from at least two respective sectors. The at least two respective sectors are from at least two different sets of a superset of sectors. The transmitted signal waveforms include signal waveforms at least nearly mutually orthogonal at least along a particular signal dimension. An advantage of such an embodiment, for example, is reduced signal interference.

Adaptive Transmission (Tx)/Reception (Rx) Pulse Shaping Filter For Femtocell Base Stations And Mobile Stations Within A Network

View page
US Patent:
8437762, May 7, 2013
Filed:
Aug 11, 2009
Appl. No.:
12/539341
Inventors:
Mehmet Yavuz - San Diego CA, US
Yu-Chuan Lin - Carlsbad CA, US
Yeliz Tokgoz - San Diego CA, US
Assignee:
QUALCOMM Incorporated - San Diego CA
International Classification:
H04B 15/00
H04M 1/00
US Classification:
455444, 455561
Abstract:
A mobile station may include a standard transmit pulse-shaping filter, a standard receive pulse-shaping filter, a narrower transmit pulse-shaping filter, and a narrower receive pulse-shaping filter. A femtocell base station may include a narrower transmit pulse-shaping filter and a narrower receive pulse-shaping filter. The mobile station may utilize the narrower transmit pulse-shaping filter for transmitting uplink signals and the narrower receive pulse-shaping filter for receiving downlink signals when it is receiving service from the femtocell base station. The mobile station may utilize the standard transmit pulse-shaping filter for transmitting uplink signals and the standard receive pulse-shaping filter for receiving downlink signals when it is receiving service from a macrocell base station.

Switching Between Different Transmit/Receive Pulse Shaping Filters For Limiting Adjacent Channel Interference

View page
US Patent:
8452332, May 28, 2013
Filed:
Aug 11, 2009
Appl. No.:
12/539385
Inventors:
Mehmet Yavuz - San Diego CA, US
Sanjiv Nanda - Ramona CA, US
Yeliz Tokgoz - San Diego CA, US
Assignee:
QUALCOMM Incorporated - San Diego CA
International Classification:
H04B 1/38
H04B 1/00
US Classification:
455561, 455 631
Abstract:
A femtocell base station includes a transmitter that transmits downlink signals to a mobile station, a receiver that receives uplink signals from the mobile station, a standard transmit pulse-shaping filter, and a narrower transmit pulse-shaping filter that limits the bandwidth of the downlink signals to a greater extent than the standard transmit pulse-shaping filter. The femtocell base station also includes a standard receive pulse-shaping filter and a narrower receive pulse-shaping filter. The femtocell base station is configured to switch between the standard transmit pulse-shaping filter and the narrower transmit pulse-shaping filter, and to switch between the standard receive pulse-shaping filter and the narrower receive pulse-shaping filter. A mobile station may switch from a standard transmit pulse-shaping filter to a narrower transmit pulse-shaping filter to limit uplink interference. A mobile station may switch from a narrower transmit pulse-shaping filter to a standard transmit pulse-shaping filter to achieve a higher data rate.

Method And Apparatus For Interference Control In Wireless Communication Systems

View page
US Patent:
20060229089, Oct 12, 2006
Filed:
Apr 7, 2005
Appl. No.:
11/102134
Inventors:
Yeliz Tokgoz - La Jolla CA, US
Mingxi Fan - San Diego CA, US
John Smee - San Diego CA, US
Jilei Hou - Carlsbad CA, US
International Classification:
H04B 7/005
US Classification:
455501000, 455067110
Abstract:
Embodiments disclosed herein relate to providing effective interference control in a wireless communication system. In one embodiment, a method for determining an interference level in a wireless communication system is described, including: determining a rise-over-thermal (RoT) metric based on an RoT received at each receiver antenna of an access network, the RoT relating to a ratio of a total energy to a thermal energy received at each receiver antenna; determining an interference-reduction factor (ρ) in relation to an interference energy reduced from the total energy received at each receiver antenna; and determining an effective rise-over-thermal (RoT) based on the RoT metric and the interference-reduction factor, the RoTrelating to the interference level in the wireless communication system. The method may further include comparing the RoTwith a threshold and relating the result of the comparison (e.g., the sector loading status) to each access terminal in communication with the access network.

Inventors:
Peter Black - San Diego CA, US
Mingxi Fan - San Diego CA, US
Yeliz Tokgoz - La Jolla CA, US
International Classification:
H04B 7/00
H04M 1/00
US Classification:
455522000, 455517000, 455562100
Abstract:
A method and system for reverse link transmit beam-forming. One method comprises using a plurality of antennas at an access terminal to wirelessly transmit signals to one or more base stations; receiving an input indicating a reverse link signal quality at the one or more base stations; and adjusting at least one of a gain and a phase of a signal to be transmitted on one or more antennas. The input may be a reverse power control (RPC) value sent from one or more base stations or a measurement of the closed-loop pilot transmit power.

Interference Management In A Wireless Communication System Using Adaptive Path Loss Adjustment

View page
US Patent:
20090137241, May 28, 2009
Filed:
Nov 24, 2008
Appl. No.:
12/276916
Inventors:
Mehmet Yavuz - San Diego CA, US
Peter J. Black - San Diego CA, US
Sanjiv Nanda - Ramona CA, US
Yeliz Tokgoz - San Diego CA, US
Assignee:
QUALCOMM Incorporated - San Diego CA
International Classification:
H04W 24/00
H04W 72/08
US Classification:
455423, 4554522
Abstract:
Interference that occurs during wireless communication may be managed by determination and application of an adaptive path loss adjustment. A method, apparatus and medium of communication determine a level of excess received interference based at least in part on out-of-cell interference (Ioc). The path loss is adjusted by an additional path loss on an uplink signal when the level of excess received interference exceeds an interference target that would cause a Rise-over-Thermal (RoT) metric to exceed stable communication.
