  • Patent number: 7400887
    Abstract: The per sector or per cell downlink capacity in a spread spectrum wireless network is determined using a single test mobile that is operating within a background of simulated co-channel interference being broadcast in each sector by all cell sites in the network whose capacity is of interest. From all sectors, an Orthogonal Channel Noise Simulator (OCNS) generates a multiple number of calibrated test signals, which are aggregated and broadcast downlink, where each transmitted test signal simulates the downlink power transmitted to a live mobile. Each component test signal in the aggregated OCNS output transmitted in each sector is a sample of a stochastic process with a set mean and standard deviation that are determined from the mean and standard deviation of the power of a real signal transmitted downlink to the test mobile as it is moved around the network's coverage area.

  • Patent number: 7171165
    Abstract: A mobile terminal selects a transmission rate for the reverse common signaling channel in response to at least one mobile-terminal-measured metric that is associated with the RF conditions of the channel. The mobile terminal is provided with information, where the information takes the form of at least one threshold level that the one or more measured metrics are compared with, to determine the rate at which at which the mobile terminal should transmit.
