SYSTEM AND METHOD FOR FLOW CONTROL IN A MULTI-POINT HSDPA COMMUNICATION NETWORK

摘要

A base station (e.g., a Node B (704) in a Multi-Point HSDPA network) calculates an amount of data to request from a network node (e.g., a radio network controller or RNC (702)). As a part of the algorithm utilized, a length of a queue at the Node B (704) for buffering the flow may be dynamically adjusted in an effort to optimize the trade-off between buffer underrun and skew. Further, a network node (e.g., the RNC (702)) responds to Node B (704) flow control requests. Here, the RNC (702) may determine the amount of data to send to the Node B (704) in response to the flow control message from the Node B (704), and may send the data to the Node B (704). In various aspects of the present disclosure involving a Multi-Point HSDPA system, the flow control algorithm at the RNC (702) coordinates packet flow to the primary serving cell and the secondary serving cell for the UE (708).
