Publication number: 20160081096Abstract: Methods and apparatus for performing dynamic channel selection are provided. In an example, a method includes receiving, at a central self-organizing network server, data from an access point (AP) including a number of stations associated with the AP. The method includes calculating downlink capacities for the associated stations and selecting a channel for the AP which maximizes a pre-defined network utility that is based on the downlink capacities. Further, it is determined if the network utility gain resulting from selecting the channel exceeds a threshold when compared to a previous channel selection state. If the network utility gain exceeds the threshold, a channel change command is issued to the AP, directing the AP to use the selected channel to communicate with a specific station.Type: ApplicationFiled: September 12, 2014Publication date: March 17, 2016Inventors: Marc Walter WERNER, Andrea GARAVAGLIA, Patrick STUPAR, Kambiz AZARIAN YAZDI

Patent number: 9167495Abstract: To determine a cell for usage in wireless communication, a signal-to-noise ratio or a signal-to-power ratio can be used in selecting an appropriate cell. However, cell selection can also configure to take both signal-to-noise ratio and signal-to-power ratio into account. Multiple available cells can be analyzed and a highest ranking cell can be selected through balancing the aforementioned ratios. In addition, to minimize transferring between cells, a limitation can be placed such that a cell is not left unless there is better of both the aforementioned ratios at another cell.Type: GrantFiled: June 12, 2008Date of Patent: October 20, 2015Assignee: QUALCOMM IncorporatedInventors: Francesco Pica, Andrea Garavaglia, Long Duan

Patent number: 9130890Abstract: In a method of scheduling frames, a first channel of a plurality of channels is selected for a first frame. The first frame is sent across a media-independent interface to a physical-layer device for transmission on the first channel. A data rate of the media-independent interface is greater than a data rate of the physical-layer device for the first channel. After the first frame is sent across the media-independent interface, subsequent sending of frames for the first channel across the media-independent interface is disabled for a period of time that is based at least in part on rate adaption from the data rate of the media-independent interface to the data rate of the physical-layer device for the first channel.Type: GrantFiled: October 7, 2013Date of Patent: September 8, 2015Assignee: QUALCOMM IncorporatedInventors: Stephen Jay Shellhammer, Patrick Stupar, Andrea Garavaglia
