Patent number: 9143946Abstract: Systems and methodologies are described that facilitate assigning carriers to access points based on power class. Devices can accordingly evaluate cells provided by the access points to select a cell with an optimal SNR or path loss for communication regardless of power class, since lower powered cells will not be interfered by higher powered cells communicating over different carriers.

Publication number: 20150133142Abstract: Cluster-based optimization of antenna tilts in a wireless network and other related aspects are presented herein. A screening component can receive information indicating wireless conditions of respective wireless access points of a geographical region, select, based on a performance criterion, an access point of the respective wireless access points, and group the access point and an other access point of the respective wireless access points into a representation of a cluster of access points. Further, an optimization component can derive antenna tilt values for respective access points of the cluster of the access points in response to a simulation of an application of the antenna tilt values to the respective access points. Furthermore, an implementation component can direct the antenna tilt values to respective components of the respective access points.Type: ApplicationFiled: January 22, 2015Publication date: May 14, 2015Inventors: Hyun Ok Lee, Vibhav Arun Kapnadak, Fereidoun Tafreshi, Xiaojun Tang, Ernest Tinyork Tsui, Gustavo Enrique Ulffe Whu

Publication number: 20150133089Abstract: Initiating a virtual presence at a physical access point in response to a request for a service from a wireless access device is provided. A particular wireless service may be provided to a subscriber on an on-demand basis according to location and/or type of service requested. The service may be terminated when demand for the service comes to an end whereby a common wireless service infrastructure may be shared amongst service providers thus eliminating the need for radio channel coordination and otherwise enhancing service quality for those service providers.Type: ApplicationFiled: December 30, 2014Publication date: May 14, 2015Inventors: Ted Tsei Kuo, Ming-Jye Sheu, Tian-Yuan Lin, Tyan-Shu Jou

Patent number: 9031597Abstract: A method includes receiving in a mobile communication terminal signals from multiple cells that coordinate transmission of the signals with one another in a Cooperative Multipoint (CoMP) scheme. At least first and second Channel Quality Indicators (CQIs), for respective communication channels over which the signals are received, are calculated in the terminal based on the received signals. The second CQI is differentially encoded relative to the first CQI. Feedback information, including the first CQI and the differentially-encoded second CQI, is transmitted from the terminal.Type: GrantFiled: November 9, 2012Date of Patent: May 12, 2015Assignee: Marvell World Trade Ltd.Inventors: Yan Zhang, Krishna Srikanth Gomadam

Patent number: 9031607Abstract: Systems, methods, and computer-readable media, for facilitating selection of networks are provided. In some embodiments, the method includes receiving at a user device a first signal via a first channel of a MIMO-enabled network and a second signal via a second channel of the MIMO-enabled network. A first power associated with the first signal and a second power associated with the second signal are identified. The first power associated with the first channel and the second power associated with the second channel are used to determine an undesired connection of the user device with the MIMO-enabled network.Type: GrantFiled: February 28, 2013Date of Patent: May 12, 2015Assignee: Sprint Communications Company L.P.Inventor: Warren Bruce Cope

Patent number: 9031032Abstract: A system and method for inter-cell interference coordination is provided. A method for controller operation includes receiving interferer information from a device served by the controller, scheduling a cell edge device based on the received interferer information, and reporting usage information of the subset of resources to neighboring controllers. The cell edge device operates in a periphery of a coverage area of the controller, and the cell edge device is scheduled to a subset of resources. The method also includes from each neighboring controller, receiving neighboring usage information of a neighboring subset of resources reserved for cell edge devices served by the neighboring controller. The method further includes scheduling a cell center device based on the received usage information from the neighboring controllers, and transmitting to scheduled devices over their respective scheduled resources. Cell center device is scheduled to resources not in the subset of resources.Type: GrantFiled: February 12, 2010Date of Patent: May 12, 2015Assignee: Futurewei Technologies, Inc.Inventors: Weimin Xiao, Oghenekome Oteri, Cornelius van Rensburg

Patent number: 9031043Abstract: A request to establish a call involving a wireless communication device (WCD) served by a radio access network (RAN) may be received. The WCD may receive signals from the RAN via a plurality of wireless coverage areas at respective signal strengths. The plurality of wireless coverage areas may be defined by the RAN. A media codec to use for the call and a target bitrate for the media codec to use during the call may be determined. Based on the target bitrate, a set of n wireless coverage areas through which the WCD and the RAN communicate during the call may be selected. The value of n may be between one and a predetermined maximum number. The set of n wireless coverage areas may be selected from the plurality of wireless coverage areas.Type: GrantFiled: September 22, 2014Date of Patent: May 12, 2015Assignee: Sprint Spectrum L.P.Inventor: Siddharth S.

Patent number: 9031568Abstract: A method and device support the use of background network scanning to enable association with a first and at least a second wireless network, for the exchange of exchange of multimedia information. Representative embodiments of the present invention may sniff radio frequency spectrum and determine at least one characteristic of detected wireless networks having capacity for exchange of the multimedia information. More than one wireless network may be identified for use in exchanging the multimedia information, which may be communicated concurrently over the identified wireless networks. User defined criteria may be employed in adjusting communication of the multimedia information to meet a quality of service level desired by a user. A lack of wireless network capacity may result in adjustments to, for example, protocols used to represent multimedia information, frame rate, and spatial or color resolution, in order to maintain or enable communication.Type: GrantFiled: March 30, 2005Date of Patent: May 12, 2015Assignee: Broadcom CorporationInventors: Jeyhan Karaoguz, James D.
