Patent number: 10159006Abstract: A wireless communications system supports wireless connections between base station sector attachment points and wireless terminals. Individual wireless connections correspond to one of a downlink-macrodiversity mode of operation and a downlink non-macrodiversity mode of operation. A wireless terminal has, for each of its current connections, a base station assigned dedicated control channel for communicating uplink control information reports. The uplink control information reports include downlink signal-to-noise ratio reports based on measured received pilot channel signals. If a connection corresponds to a macrodiversity mode of operation, a reporting format for the SNR report is used which reports (i) an SNR value and (ii) an indication as to whether or not the connection is considered a preferred connection by the wireless terminal. If a connection corresponds to a non-macrodiversity mode of operation, a reporting format for the SNR report is used which reports an SNR value.Type: GrantFiled: July 29, 2015Date of Patent: December 18, 2018Assignee: QUALCOMM IncorporatedInventors: Arnab Das, Pablo Anigstein, Murari Srinivasan, Junyi Li

Patent number: 9788235Abstract: A network device may make a determination that a first backhaul connection, which serves a first base station, is congested and that a second backhaul connection, which serves a second base station, is not congested. This determination may be made based on a first periodic data cap imposed on the first backhaul connection, a traffic load on the first backhaul connection, a second periodic data cap imposed on the second backhaul connection, and a traffic load on the second backhaul connection. In response to the determination, the network device may configure a value of a cellular communication parameter utilized by one or both of the base stations. The configuration may comprise periodic adjustments of the value of the cellular communication parameter. The periodic adjustments may cause one or more mobile devices to be handed-over between the first base station and the second base station.Type: GrantFiled: January 15, 2016Date of Patent: October 10, 2017Assignee: Google Inc.Inventors: Siddharth Ray, Murari Srinivasan, Milo Steven Medin

Patent number: 9756525Abstract: A method includes receiving a connection request from a mobile device at a network device to allow connection of the mobile device to a core network of the first service provider through a first base station and determining whether a backhaul connection between the core network of the first service provider and the first base station is congested by the network device. The backhaul connection is determined to be congested when L is greater than (D?B)/T. When the first backhaul connection is determined to be congested, the method also includes preventing the first base station from connecting the mobile device to the core network.Type: GrantFiled: December 22, 2014Date of Patent: September 5, 2017Assignee: Google Inc.Inventors: Siddharth Ray, Murari Srinivasan, Milo Steven Medin

Patent number: 9736752Abstract: Methods and apparatus for routing messages between an end node and an access node via another access node are described. Physical layer identification information is used when identifying a remote, e.g., adjacent, access node as a message destination. Thus, when a connection identifier based on one or more physical layer identifiers is available to a wireless terminal, e.g., from one or more downlink signals received from a destination access node, the wireless terminal can use the connection identifier corresponding to the destination node to route a message via an access node with which it has an established uplink connection. Such connection identifier information can be used even when other addressing information, e.g., network layer address information, associated with the destination access node, may not be available to the wireless terminal.Type: GrantFiled: December 22, 2005Date of Patent: August 15, 2017Assignee: QUALCOMM IncorporatedInventors: Rajiv Laroia, Pablo Anigstein, Vladimir Parizhsky, Murari Srinivasan, George Tsirtsis

Patent number: 9572179Abstract: Methods and apparatus for communicating transmission backlog information are described. Reporting control factors are utilized to expand reporting possibilities for a fixed bit size request report. At least one report control factor is determined as a function of channel quality information, power information, device capability information, and/or quality of service information. A transmission backlog report value is interpreted as a function of a reporting control factor. A wide range of quantization schemes for reporting transmission backlog information are facilitated corresponding to a small bit size report. A communications device can adaptively select a quantization request level closely matched to its current needs such as to provide an accurate representation of its current traffic channel resource needs.Type: GrantFiled: July 14, 2006Date of Patent: February 14, 2017Assignee: QUALCOMM IncorporatedInventors: Arnab Das, Sundeep Rangan, Pablo Anigstein, Murari Srinivasan

Patent number: 9191840Abstract: A wireless terminal receives a broadcast uplink interference report request conveying a requested report type and/or a locally unique base station identifier. The wireless terminal receives and measures broadcast reference signals, e.g., beacon and/or pilot signals, transmitted from a plurality of base station attachment points. Specific type interference reports relate a current serving connection base station attachment point to a selected base station attachment point corresponding to the received base station identifier. Generic type interference reports relate a current serving base station connection attachment point to other unspecified base station attachment points whose broadcast reference signals have been detected by the wireless terminal. Sub-types of generic reports include summation function and maximum function reports. Timing information is sometimes used to determine report sub-type and/or sector type of the selected attachment point.Type: GrantFiled: July 14, 2006Date of Patent: November 17, 2015Assignee: QUALCOMM IncorporatedInventors: Rajiv Laroia, Junyi Li, Sundeep Rangan, Murari Srinivasan, Prashanth Hande, M.
