Methods, radio base station and radio network controller

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. A corresponding RBS and RNC are also presented.

1. A method performed in a first radio base station (RBS) in communication with a radio network controller (RNC), the RNC being configured for multi-flow High-Speed Downlink Packet Access (HSDPA) operation wherein packet data units (PDUs) are communicated toward a user equipment (UE) node via the first RBS and at least one second RBS, the method comprising:
detecting PDU drop events or loss events, or both; and communicating information from the first RBS to the RNC, in response to said detecting, the information notifying the RNC of which PDUs are affected by the detected events;wherein the information communicated from the first RBS to the RNC, in response to said detecting, comprises one or more of:
a sequence number of an Iub data frame in which a dropped PDU was received by the first RBS; and a Delay Reference Time (DRT) and Cyclic Redundancy Check (CRC) of an Iub data frame in which a dropped PDU was received by the first RBS.
