  • System and method for load rebalancing
    Patent number: 10187838
    Abstract: A system and method for load rebalancing are provided. A node B selects a subset of carriers from a plurality of carriers of the node B according to effective usages for the plurality of carriers, determines a heavily loaded carrier and a lightly loaded carrier from the subset of carriers according to effective usages of the subset of carriers, select a mobile device assigned to the heavily loaded carrier as a candidate for handoff, and performs a handoff of the selected mobile device from the heavily loaded carrier to the lightly loaded carrier.
    Type: Grant
    Filed: November 3, 2015
    Date of Patent: January 22, 2019
    Assignee: Futurewei Technologies, Inc.
    Inventors: Mark Ernest Newbury, Keith Butterworth, Zinan Lin, Alpaslan Gence Savas, Matthijs A. Visser

  • Method for dynamically estimating noise floor and rise over thermal (ROT)
    Patent number: 7489901
    Abstract: The present invention provides a method for dynamically estimating noise floor by continuously updating a noise floor value based on the noise floor value and sampled receive strength indications. In an alternative, the noise floor may be updated based on sampled receive strength indications and the reverse link loading value. In yet another alternative, the noise floor may be updated based on sampled receive strength indications and a range relative to a reference noise floor value.

  • Methods and devices for controlling RF, multi-carrier amplifier signal power
    Patent number: 7453945
    Abstract: The input (and output) power of a multi-carrier amplifier can be controlled to allow the amplifier to operate at high RF power levels and still remain within a power rating profile. The amplifier (or amplifiers) power is controlled using an aggregate scaling factor. The aggregate scaling factor is generated from a plurality of amplifier scaling factors. Each amplifier scaling factor is generated based on a comparison of a time-averaged total power and a corresponding threshold.
