<p>The present invention discloses a frame constructing method for use in a multi-hop wireless access network, the method comprising the steps of: determining Relay Stations (RSs) and Mobile Stations (MSs); setting a DL sub-frame; setting an UL sub-frame; and constructing a completed frame based on the UL sub-frame and the DL sub-frame; wherein the step of setting the DL sub-frame comprises a step of setting a DL relay sub-frame field for DL relay information sent to the RS; and the step of setting the UL sub-frame comprises a step of setting an UL relay sub-frame field for UL relay information sent from the RS. The present invention further discloses a corresponding frame processing method and a device, base station, relay station and system for implementing the method. According to the present invention, the synchronization in the whole network system is ensured, and the handover operation when the MS moves is simplified. Moreover, the situation that the base station and the relay stations use different frequencies can be supported. Additionally, the delay of traffic transmission is decreased.</p> |
