Abstract:
A system, method, and apparatus is provided for performing carrier aggregation (CA) radio resource management (RRM). The system, method, and apparatus can receive a configuration message having configuration information from an access node; determine a measurement period for a secondary cell (SCell) and a cell identification delay based upon the configuration information; identify a new detectable cell on a secondary component carrier (SCC) as the SCell within the cell identification delay; perform a measurement for a CA operation within the measurement period; and report the measurement to the access node. The configuration message can be a Radio Resource Control (RRC) message. The measurement for the CA operation can be a measurement of the SCell on the SCC. The system, method, and apparatus can multiply a measurement control parameter by a factor less than five (5) to determine the measurement period and can multiply a measurement control parameter by a factor less than twenty (20) to determine the cell identification delay. The system, method, and apparatus can further perform an action with respect to the SCell in response to the measurement.
