摘要 |
After checking a status of frequency band usage of a primary system by preliminary sensing, a master node transmits to slave nodes a sensing request containing a target frequency band for cooperative sensing. The slave nodes perform spectrum sensing according to specified parameters and send, as responses, results thereof to the master node. The master node collectively receives these results, comprehensively determines the sensing results of the slave nodes, and makes a final determination on whether or not the target frequency band is available.
