QUIET PERIOD MANAGEMENT IN WIRELSES NETWORKS

摘要

Spectrum agile devices use non or under utilized portions of the radio spectrum to communicate. However, when a primary user of the channel starts operation, the spectrum agile device must typically vacate the channel. Thus, spectrum agile devices use quiet periods to sense whether a primary device is present. Quiet Periods can be scheduled or on-demand, and quiet periods can be initiated so that the quiet periods of different channels do not overlap.
