  • Publication number: 20140120932
    Abstract: Femtocells in a self-organizing network (SON) sniff their wireless fidelity (WiFi) environments to identify WiFi footprints of the femtocells. The WiFi footprints of each femtocell are sent to a femtocell gateway. The femtocell gateway receives WiFi footprint data from a plurality of femtocells and determines if there is a common WiFi footprint between the femtocells. The femtocells with exclusive WiFi footprints are allocated the same network parameters. The femtocells with common WiFi footprint are allocated different network parameters.

  • Patent number: 8666331
    Abstract: Cellular processors are cascaded to provide different configurations, which result in higher-capacity base stations, increased numbers of simultaneous users over one frequency band, and/or aggregation of several carriers while still using only one radio frequency (RF) chipset. The processors are aligned in both time and frequency, with each processor having a data port that allows data exchange with the other processors. The data alignment and exchange allow the processors, in the aggregate, to act as a single unit, resulting in a scalable architecture that can accommodate different system configurations.

  • Publication number: 20130281080
    Abstract: A system, method, and apparatus to facilitate the synchronization of oscillators between members of a Heterogeneous Network (HetNet) to form a self-synchronizing network (SSN). The network members are configured to broadcast information indicative of the reliability of their oscillator. Network members attempt to look for reliable sources such as those originating from a macrocell base station or GPS. If such a source is found, the member cell updates it clock accuracy confidence level number (CACL) to indicate this. Network members also share information regarding the frequency offsets between one another. Every cell member then applies a weighted average function to determine how to update its own oscillator and CACL value accordingly. Cell members can also update their functionality, such as RF power level, in response to varying degrees of CACL values. This operation results in a convergence of all cell members to the most accurate oscillator offset value.

  • Publication number: 20130244666
    Abstract: User equipment (UE) in a cellular communication system is capable of both high data rate uses such as streaming video and low data rate uses such as voice. UE in accordance with the disclosure camps on to a cell with a narrow bandwidth downlink when its data rate requirements are low, rather than a cell with a wide bandwidth download. Since the computational burden of processing the narrow bandwidth downlink signals is less than that for processing the wide bandwidth downlink signals, a power reduction in the UE is realized from the reduced computational load. A normal handover between cells with wide and narrow bandwidth downlinks can be used. Alternatively, a single cell can dynamically change its downlink bandwidth resulting in a reduced computational load and reduced power consumption in the UE.

  • Publication number: 20130244654
    Abstract: Provided is coordinating user equipment handover in a heterogeneous network cell that includes a plurality of overlaying cell layers. An access controller of a network core receives a first parameter relating to signal quality for the user equipment with a serving cell of a cell layer of the plurality of overlaying cell layers, and receives a second parameter based upon a velocity estimation of user equipment within the heterogeneous network cell. When the first parameter indicates a cell boundary, the access controller forms a handoff decision to a cell base station of a cell layer of the plurality of overlaying cell layers based upon the second parameter, and initiates a handoff to the cell base station based upon the handoff decision.

  • Publication number: 20130095835
    Abstract: Embodiments of this disclosure include methods in which a core network controller determines which femtocell base station to handover a cellular device to. Methods include comparing a cell parameter difference provided by a base station with a cell parameter difference provided by the cellular device. The cell parameter difference provided by the base station is the cell parameter difference between the base station and each neighboring base station. The cell parameter difference provided by the cellular device is the cell parameter difference between the base station through which the cellular device is currently associated with to the core network and each neighboring base station. The core network controller compares the cell parameter difference provided by the cellular device with the cell parameter difference provided by the base station. The core network hands the cellular device to the base station when the cell parameter difference provided by each are substantially equivalent.

  • Patent number: 8351412
    Abstract: Methods and apparatus are provided for blind transport format detection using Discontinuous Transmission (DTX) detection. According to one aspect of the invention, the transport format that was used to transmit information is determined by identifying a transition between a Discontinuous Transmission segment and a data segment included in the transmitted information; and determining the transport format based on a location of the transition of the Discontinuous Transmission segment. A cyclic redundancy check can optionally be performed for a plurality of possible transport formats, and then the step of identifying a transition can be limited to those transport formats having a valid cyclic redundancy check.
