Wireless-system flow control and packet scheduler interface

Abstract:

A method for multi-path packet scheduling in a wireless communication system comprises collecting of measurements of queue state information about buffers of a plurality of transmit nodes. A rate budget is calculated based on the collected measurements of queue state information. The rate budget comprises commanded bit rates and/or data volumes for each transmit node for a subsequent sampling period. Data representative for the rate budget is provided from the packet-flow controller node over a packet scheduling interface to a packet scheduler node. Packets to be sent to each of the plurality of transmit nodes in a subsequent sampling period are scheduled depending on the received rate budget. Nodes for multi-path packet scheduling in a wireless communication system are also disclosed.
