Patent ID: 8284667

Claim:
A method for operating a radio network controller (RNC) in a wireless network, the RNC being in communication with a user equipment (UE), the method comprising: setting a radio link control (RLC) transmission window size for the UE for a flow at initial data flow set up; determining whether a congestion exists on an hub transport network (TN) connection between the RNC and a Node B for the flow in an uplink direction; reducing the RLC transmission window size when the congestion exists; and notifying the UE regarding the reduced RLC transmission window size, where the flow is a flow of Medium Access Control-d Protocol Data Units (MAC-d PDUs) formed from RLC PDUs exchanged between the RNC and the UE, and where the RLC transmission window size sets a maximum amount of outstanding data for the flow that can be transmitted from the UE to the RNC in one or more RLC PDUs until an acknowledgment (ACK) is sent from the RNC.
