Patent ID: 8369221

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 a flow associated with the UE at initial flow set up; determining whether a congestion message is received from the Node-B; and reducing the RLC transmission window size for the flow when it is determined that the congestion message is received from the Node-B, wherein 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 wherein the RLC transmission window size sets a maximum amount of outstanding data for the flow that can be transmitted from the RNC to the UE in one or more RLC PDUs until an acknowledgment (ACK) is received from the UE.
