Publication number: 20150333812Abstract: Certain aspects of the present disclosure relate to techniques for achieving adaptive channel state information (CSI) feedback rate in multi-user communication systems. A rate by which CSI feedback can be transmitted from each user station of a wireless system to a serving access point may be adjusted based on evolution of a channel between that user station and the access point.Type: ApplicationFiled: July 22, 2015Publication date: November 19, 2015Inventors: Gregory Breit, Santosh Abraham, Sameer Vermani, Hemanth Sampath, Vincent Knowles Jones, IV

Patent number: 9112741Abstract: Methods and apparatuses are proposed for supporting one or more user-dependent channel state information (CSI) feedback rates in a downlink spatial division multiple access (SDMA) system. For certain aspects, an access point (AP) may receive a channel evolution feedback from one or more stations and send a request for CSI to the stations whose CSI values need to be updated. For certain aspects, the AP may poll the stations for updated CSI values. For certain aspects, deterministic back-off timers may be assigned to the stations indicating when to send their CSI feedback. The proposed methods may improve system performance.Type: GrantFiled: September 16, 2010Date of Patent: August 18, 2015Assignee: QUALCOMM IncorporatedInventors: Gregory A.

Patent number: 8160648Abstract: Receiver diversity in a wireless device is controlled in response to operating conditions, transmission requirements, and control settings. The control of diversity reduces power consumption by enabling receive diversity on given conditions. Operating conditions, transmission requirements, and control settings are used separately or used in conjunction to determine whether benefits of multi-antenna receive diversity, such as higher link capacity, higher data throughput, lower transmit power, and lower error rate, warrant the higher power cost of the diversity.Type: GrantFiled: April 28, 2010Date of Patent: April 17, 2012Assignee: Qualcomm IncorporatedInventors: Fatih Ulupinar, Gregory A. Breit, Brian C. Banister, Edward G. Tiedemann, Jr.

Patent number: 7454181Abstract: A mobile device comprises a receiver unit that has at least two receivers to implement multi-antenna receive diversity. A control unit estimates, at the mobile, an amount of utilization by a traffic channel of the mobile of total transmission power capacity at a base station. The mobile applies multi-antenna receive diversity in the mobile device based on the power capacity utilization. The mobile estimates an amount of power a network is transmitting to the mobile relative to a pilot reference. Other indicators are based on quality of the traffic channel between the mobile and the network, capacity limiting resources, a number of sectors in a soft hand-off in a wireless system, etc. The indicators are used to control application of multi-antenna receive diversity in a mobile device.Type: GrantFiled: March 4, 2005Date of Patent: November 18, 2008Assignee: QUALCOMM IncorporatedInventors: Brian C.

Publication number: 20060194553Abstract: Systems, methods, apparatus, processors and computer-readable media include a radiated testing module that executes a predetermined radiated performance test on a wireless device. The test dictates various performance-related parameters to measure and log at each of a plurality of predetermined positions. Further, the wireless device receives synchronization information operable to enable synchronization between the logged measurements and each of the positions. The synchronized log allows the wireless device, or another apparatus, to determine a radiated performance characteristic based on a predetermined analysis protocol. Further, the described embodiments allow for the determination of several radiated performance characteristics in a single test, using a single, unaltered wireless device.Type: ApplicationFiled: October 24, 2005Publication date: August 31, 2006Inventors: Ernest Ozaki, Kenny Fok, Paul Seckendorf, Tia Cassett, Patrick Tierney, Gregory Breit, Jing Li

Patent number: 6183425Abstract: A device to record and analyze habitual daily activity in terms of the history of gait-related musculoskeletal loading is disclosed. The device consists of a pressure-sensing insole—placed into the shoe or embedded in a shoe sole—which detects contact of the foot with the ground. The sensor is coupled to a portable battery-powered digital data logger clipped to the shoe or worn around the ankle or waist. During the course of normal daily activity, the system maintains a record of time-of-occurrence of all non-spurious foot-down and lift-off events. Off line, these data are filtered and converted to a history of foot-ground contact times, from which measures of cumulative musculoskeletal loading, average walking- and running-specific gait speed, total time spent walking and running, total number of walking steps and running steps, and total gait-related energy expenditure are estimated from empirical regressions of various gait parameters to the contact time reciprocal.Type: GrantFiled: October 13, 1995Date of Patent: February 6, 2001Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventors: Robert T.
