摘要

It is presented a method performed in a first radio base station RBS in communication with a radio network controller RNC. The RNC is configured for multi flow HSDPA High Speed Downlink Packet Access operation and packet data units PDUs are communicated toward a user equipment UE node via the first RBS and at least one second RBS. The method comprises: detecting PDU drop events and/or loss events; and communicating information from the RBS to the RNC notifying of each detected PDU drop event and/or loss event.
