Abstract
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.
Claims10
A method for use in a Node B having a buffer, the method comprising:
- monitoring an amount of data within the buffer;
- monitoring an amount of additional data the buffer may accept;
- calculating a capacity allocation;
- transmitting the capacity allocation;
- and
- receiving data in response to the capacity allocation, wherein the received data is equal to or less than the capacity allocation.
A Node B comprising:
- a buffer;
- a processor configured to monitor an amount of data within the buffer, monitor an amount of additional data the buffer may accept, and calculate a capacity allocation;
- a transmitter configured to transmit the capacity allocation;
- and
- a receiver configured to receive data in response to the capacity allocation, wherein the received data is equal to or less than the capacity allocation.
