COGNITIVE FLOW CONTROL BASED ON CHANNEL QUALITY CONDITIONS

摘要

A system and method which improve the performance of a wireless transmission system by intelligent use of the control of the flow of data between a radio network controller (RNC) and a Node B. The system monitors certain criteria and, if necessary, adaptively increases or decreases the data flow between the RNC and the Node B. This improves the performance of the transmission system by allowing retransmitted data, signaling procedures and other data to be successfully received at a faster rate, by minimizing the amount of data buffered in the Node B. Flow control is exerted to reduce buffering in the Node B upon degradation of channel qualities, and prior to a High Speed Downlink Shared Channel (HS-DSCH) handover.

1. A method performed by a wireless device having a buffer, the method comprising:
monitoring an amount of data within the buffer and determining whether it is acceptable for additional data to be sent to the wireless device; calculating a capacity allocation associated with the wireless device; transmitting the capacity allocation to a network device; and receiving data at the wireless device in response to the transmitted capacity allocation, wherein an amount of the received data is equal to or less than the capacity allocation.
