  • Apparatus and method for dynamically controlling spectrum access
    Patent number: 10390364
    Abstract: A process for dynamically controlling spectrum access includes: collecting occupancy data; applying nonparametric estimation to the occupancy data; determining a cumulative hazard function; receiving a service request to occupy the wireless communication channel from a secondary user; accepting the service request from the secondary user if the wireless communication channel is unoccupied by the primary user; calculating a maximum duration for which the secondary user may occupy the wireless communication channel; determining a probability that a remaining idle time of the primary user is greater than an occupation time of the wireless communication channel of the secondary user; granting access to the secondary user for occupation of the wireless communication channel if the probability is greater than a selected probability threshold; and denying access to the secondary user for occupation of the wireless communication channel if the probability is less than the selected probability threshold to dynamically
