1. A method for performing carrier aggregation (CA) radio resource management (RRM) measurement, the method comprising:
receiving, by a user equipment (UE) from an access node, a configuration message having a MeasCycleSCell parameter that indicates a measurement cycle designated for performing the CA RRM measurement on a secondary cell (SCell) for the CA, the MeasCycleSCell parameter being selected from among a plurality of candidate values that are applicable to the CA RRM measurement on the SCell, at least one candidate value from among the plurality of candidate values being smaller than a smallest candidate value within a corresponding wireless technical specification;
determining, by the UE, a measurement period for performing the CA RRM measurement on the SCell for the CA, the determining the measurement period comprising multiplying the MeasCycleSCell parameter by a measurement period factor that is selected from among a plurality of measurement period factors that are applicable to the CA RRM measurement on the SCell, at least one measurement period factor from among the plurality of measurement period factors being smaller than a smallest measurement period factor within the corresponding wireless technical specification;
determining, by the UE, a cell identification delay for performing the CA RRM measurement on the SCell for the CA, the determining the cell identification delay comprising multiplying the MeasCycleSCell parameter by a cell identification delay factor that is selected from among a plurality of cell identification delay factors that are applicable to the CA RRM measurement on the SCell, at least one cell identification delay factor from among the plurality of cell identification delay factors being smaller than a smallest cell identification delay factor within the corresponding wireless technical specification;
identifying, by the UE, a new detectable cell on a secondary component carrier (SCC) as the SCell within the cell identification delay;
performing, by the UE, the CA RRM measurement of the SCell on the SCC within the measurement period; and
reporting, by the UE, the CA RRM measurement to the access node.
