METHOD AND SYSTEM FOR DATA TRAFFIC SCHEDULING

摘要

A method and system for performing data traffic scheduling in a point-multipoint time division duplex network is disclosed, wherein data to be sent to and from a central access point and multiple remote subscriber terminals is respectively queued in respective traffic queues held at each terminal and in the access point, further phantom traffic queues reflecting the queues held at each subscriber terminal being further maintained at the access point in order to provide knowledge of the traffic to be sent on the uplink. A cell scheduler is further provided in the access point which acts to schedule transmission slots to each subscriber terminal in both the upstream and downstream directions based on the queued data traffic, the transmission slot scheduling then being communicated to each subscriber terminal in a broadcast manner.
