Abstract
Official abstract text for this publication.
An apparatus and method for supporting heterogeneous systems in a multi-hop relay wireless communication system are provided. In a method of transmitting and receiving a DownLink (DL) frame of a Base Station (BS) in a multi-hop relay wireless communication system employing heterogeneous systems, the DL frame of the BS includes a legacy zone for communication with a legacy Mobile Station (MS), an access zone of a new zone for communication with a new MS, and a relay zone of the new zone for communication with a new Relay Station (RS). The method includes transmitting DL data to the legacy MS in the legacy zone, transmitting the DL data to the new MS in the access zone of the new zone, and transmitting the DL data to the new RS in the relay zone of the new zone.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of transmitting and receiving an UpLink (UL) frame of a Base Station (BS) in a multi-hop relay wireless communication system using OFDMA (Orthogonal Frequency Division Multiple Access) scheme employing heterogeneous systems, wherein the UL frame of the BS comprises a legacy zone for communication with a legacy Mobile Station (MS), an access zone of a new zone for communication with a new MS, and a relay zone of a new zone for communication with a new…
