Abstract:
The method and apparatus disclosed herein enable interference suppressed information (information about interference after interference suppression to be provided to the Radio Network Controller (RNC) and/or to surrounding Radio Base Stations (RBSs)), thereby providing better radio resource management for hot spots and/or allowing the RBSs to better understand their impact on surrounding cells. Generally, a network node in the wireless network signals interference suppressed information, e.g., an interference suppressed load or overload indicator, an interference suppressed neighbor cell interference, and/or an interference suppressed noise floor to a remote node in the wireless network to facilitate radio resource management. Further, a radio network controller in the wireless network may manage the interference in cells based on the interference suppressed information by generating an interference management instruction based on the interference suppressed information, and sending the interference management instruction to the radio base station to control one or more interference management settings, e.g., a power control setting, a load threshold, etc.
