  • Apparatus and method for estimating a velocity of a mobile station in a mobile communication system
    Patent number: 7369876
    Abstract: A base station apparatus and method for estimating a velocity of a mobile station in a mobile communication system are provided. In the apparatus and 9 method, a channel estimator receives a signal on a radio channel from the mobile station and performs channel estimation using the received signal. A velocity estimator detects a power spectrum value of the channel estimator, and provides the channel estimator with a channel estimation coefficient for use during channel estimation according to a Doppler shift frequency value of power estimated from the mobile station when the velocity of the mobile station is unchanged.

  • Method of managing resources for high-speed packet data service in a mobile communication system
    Publication number: 20050128972
    Abstract: A method of managing resources allocated for HSDPA in a mobile communication system is provided. Upon initialization of HSDPA hardware, a Node B checks the status of available HSDPA resources and reports it to an RNC. If the Node B senses a change or failure in the HSDPA hardware, it checks the HSDPA resource status and reports it to the RNC. Therefore, resources are efficiently allocated for HSDPA and resource switching occurs quickly.
