METHOD AND DEVICE FOR TRANSMISSION SCHEDULING IN COGNITIVE RADIO SYSTEM

摘要

Embodiments of the present application relate to the field of radio communications. Disclosed are a method and device for spectrum sensing in a cognitive radio (CR) system, for use in increasing the performance of the CR system. In the present application, a central management device determines multiple sensing nodes capable of sensing a target frequency and geolocation information of an authorization system corresponding to the target frequency, divides the multiple sensing nodes into multiple cooperative sensing clusters, assigns a sensing task to each cooperative sensing cluster, where the sensing task comprises time information for spectrum sensing with respect to the target frequency, and notifies the sensing nodes in the corresponding cooperative sensing cluster of the sensing task assigned to each cooperative cluster, and, the sensing nodes sense a spectrum with respect to the target frequency on the basis of the sensing task as notified. Employment of the present solution allows for increased performance of the CR system.
