Abstract

A method and apparatus for cooperative relaying in wireless communications is provided. An efficient and simplified relay scheme is disclosed that transitions between different modes on a per packet basis using scheduling information or switching information included in the packet, without requiring link reconfiguration. The cooperative relay scheme benefits further from the use of cooperative relaying protocols that emphasize centralized scheduling. One protocol emphasizes physical layer cooperation via synchronized transmissions and distributed space-time coding and the other protocol emphasizes medium access control (MAC) layer cooperation using different MAC flows or messages.
