DYNAMIC ON-OFF SPECTRUM ACCESS SCHEME TO ENHANCE SPECTRUM EFFICIENCY

摘要

The following invention related to a dynamic on-off spectrum access scheme that will coordinate among different cells, sharing the same spectrum band and enhance spectrum efficiency. Based on the proposed scheme, in particular, the cells or sectors are classified to different types according to their geographical locations. Different types of cells or sectors occupy the total available frequency in a time-sharing fashion, and the duration or priority of the 'on' state for each type is chosen based on users' quality of service (QoS) demand.
