A method is provided for a base station set (NODE B) adapted for RLC and MAC-hs signaling in acknowledged mode (AM), the base station set at least forwarding protocol data units (MAC-d PDU) from a Radio Network controller (RNC) to a user entity (UE), the method comprising the steps of monitoring (1) the MAC layer of the transmission entity of the base station set (1), if a MAC discard has occurred in the MAC layer (3), that is, protocol data units (PDU's) have been deleted in the input buffer of the base station set (NODE B), transmitting (7) a discard notification message from the MAC transmission entity in the base station set to the RLC layer of the radio network controller (RNC), indicative of the discarding of protocol data units. There is moreover provided a method for a radio network controller (RNC) adapted for RLC and MAC-hs signaling in acknowledged mode (AM) and a method for a user entity (UE) adapted for RLC and MAC-hs signaling.
