Abstract

A system and method for providing power control in a multi-layer communication system includes a first step of defining a first power level and a second power level for control channel signal transmissions from an underlay cell, wherein the first power level is higher than the second power level. A next step includes establishing a first period and a second period for control channel signal transmissions. A next step includes providing, by the underlay cell, control channel signals at the first power level during the first period and the second power level during the second period.
