摘要： In a wireless communications network using relay stations between the network controller and at least some of the subscriber stations, the total network throughput may be increased by using spatial multiplexing between the network controller and some relay stations. In networks with multiple tiers of relay stations, a relay station may dedicate some sub-channels to communicating directly with subscriber stations and dedicate other sub-channels to communicating with other downstream relay stations.
