Abstract
A method and transceiver in a secondary system for utilizing channel bandwidths allocated to a primary system. A secondary system transceiver receives a primary system signal, re-transmits a delayed version of the primary system signal, and communicates with secondary system equipment utilizing secondary system signals within at least part of a bandwidth of at least one channel of the primary system. The re-transmission of the primary system signal allows the use of primary system channels by the secondary system without adversely affecting the primary or secondary system users.
