Patent number: 9480054Abstract: Methods and apparatus for mitigating interference which are well suited for high density deployments of small base stations are described. In various embodiments, control channel resources are intentionally not fully utilized. A control channel resource utilization parameter is set, e.g., as a function of interference, to limit base station average transmission power used for transmitting signals on control channel resources. By controlling utilization of control channel resources, e.g., by limiting resource utilization to result in a lower than possible, e.g., permitted, average transmission power level, the base station constrains the amount of interference to other nearby devices, e.g., base stations and UE devices. Nearby base stations operate and/or are controlled in a similar manner. As a result, nearby base stations which are causing interference to one another will reduce inter-base station interference.Type: GrantFiled: January 30, 2015Date of Patent: October 25, 2016Assignee: LUMINATE WIRELESS, INC.Inventors: Brett Schein, Amit Butala

Patent number: 9467910Abstract: Methods and apparatus for supporting handovers which are hidden from a Mobility Management Entity (MME) as well as handovers which are not hidden from the MME are described. A gateway, e.g., a home gateway (HGW), in a communications system acts as a concentration point for a plurality of small cell HeNBs. Two types of handovers, a visible handover and a hidden handover are supported. With a hidden handover, the handover is hidden from the SGW and the MME, thus reducing backhaul control signaling and loading on the SGW and MME. A gateway, e.g., a home gateway (HGW), receives a path switch request message for a user equipment (UE) device from a target access point, e.g., a home eNB (HeNB). In some embodiments the gateway, e.g., the HGW, decides whether a requested handover should be visible or should be hidden, and then performs a handover implementation in accordance with its decision.Type: GrantFiled: July 11, 2014Date of Patent: October 11, 2016Assignee: LUMINATE WIRELESS, INC.Inventors: Julien Laganier, Amit Butala

Publication number: 20160262059Abstract: Methods and apparatus for supporting efficient transitioning of a UE device from a source to destination base station are described. Various embodiments are well suited for use in an environment in where there may be PCI confusion. The handover mechanism is used to: (i) deliver context transfer information corresponding to the UE to one or more potential target base stations and to be available for use by other base stations and (ii) to force an initial handover attempt to fail via the use of intentionally faulty radio resource information. Following the initial handover attempt failure, the UE establishes a successful connection with the destination base station using valid radio resource information which was recovered via a received wireless broadcast signal.Type: ApplicationFiled: April 20, 2015Publication date: September 8, 2016Inventors: Amit Butala, Atul Salhotra, Brett Schein

Publication number: 20140364120Abstract: A beacon cell adapted for use in a small cell RAN includes dual identities—a beacon identity and a regular or “live” identity—in which the identities are individually configured to address differing performance requirements in the small cell RAN. The beacon identity in the cell is specially configured to meet the performance requirements for mobile user equipment (UE) to be able to quickly and easily move from a macrocell base station in a mobile operator's network to the small cell RAN using a process called “reselection.” The live identity is configured to meet all requirements for service to be provided to the UE within the small cell RAN. Once captured by the beacon identity of the beacon cell, the UE can then immediately reselect to the live identity of the cell which operates in a conventional manner.Type: ApplicationFiled: June 17, 2014Publication date: December 11, 2014Inventors: Amit Butala, Hithesh Nama, Pete Worters

Patent number: 8412103Abstract: Apparatus and methods for power control for mitigation or control of interference in a wireless communications environment. Power control techniques can consider the effectiveness of interference cancellation before making power control determinations. For example, where interference with a base station from an interfering wireless terminal is being canceled such that the effects of that interference are not adversely affecting operations of the base station, the offending terminal can be left unchanged, or its transmit power can be increased. On the other hand, where the interference cancellation operation is not able to cancel the effects of the interfering signal sufficiently, the operation can lower the uplink transmit power of the offending signal so as to not cause interference to the other base station.Type: GrantFiled: September 30, 2009Date of Patent: April 2, 2013Assignee: SpiderCloud Wireless, Inc.Inventors: Murari Srinivasan, Amit Butala, Sayandev Mukherjee

Publication number: 20120190372Abstract: A method for managing uplink signal quality at a radio node and at a macrocell and/or external cell, includes determining a first transmit power associated with a radio node of a small-cell radio access network and a second transmit power associated with a macrocell and/or an external cell. A desense value associated with an uplink of the radio node of the small-cell radio access network is provided, which enables balancing of a first signal to noise-plus-interference ratio associated with an uplink of the small-cell radio access network and a second signal to noise-plus-interference ratio associated with an uplink of the macrocell and/or external cell in relation to a downlink of the radio node, thereby managing uplink signal quality at the radio node of the small-cell radio access network and at the macrocell and/or external cell.Type: ApplicationFiled: January 20, 2012Publication date: July 26, 2012Inventors: Brett Schein, Murari Srinivasan, Peter J.
