Abstract
A method and apparatus for wireless communication may provide an RLC reset procedure tailored for a multipoint HSDPA system utilizing a plurality of disparate Node Bs to provide an RLC flow from an RNC to a UE. Some aspects of the disclosure provide for a flush request to be provided to each of a plurality of Node Bs utilized as serving cells in the multipoint HSDPA system, so that stale packets are not retained in internal buffers at the Node Bs following the RLC reset procedure. In some examples, the RLC reset procedure is only completed after confirmation that the flush of the internal buffers has been completed. Confirmation may be explicitly provided by each Node B utilizing a backhaul interface, or may be implicitly determined utilizing timers or signaling between the respective Node Bs.
