1. A method performed by an interference rejection combining joint detection receiver of a radio device, comprising:
determining categories of reference signal resource groups available for a cell to indicate different usage states of the reference signal resource groups in a communication scheduled for the radio device in the cell; and
performing signal processing per reference signal resource group, according to the categories of the reference signal resource groups, wherein the signal processing per reference signal resource group comprises determining a signal power parameter per reference signal resource group being used for reference signal transmission in the scheduled communication to facilitate detection of interference associated with different categories of reference signal resource groups.
