Common reference signal configuration for carrier aggregation

摘要

Eliminating or reducing transmission of common signals for enhanced spectral efficiency, improved support for heterogeneous networks, network energy saving possibilities, can be obtained by apparatuses and methods according to certain embodiments. A method for operating a user equipment can include receiving a measurement object from a network for detection of one or more predetermined type cells. A cell search can be conducted. When a predetermined type cell is found, cell specific reference signal hopping parameters can be determined. Then, radio resource management measurement can be performed from the cell specific reference signal hopping parameters.
