Abstract
A broadcast message transmission method of a relay station in a multi-hop relay network, which can be applied to a non-transparent centralized scheduling multi-hop relay network, includes that a base station transmits a message to be broadcasted to the relay station, the relay station returns an acknowledgement header to the base station after it has received the message, the base station transmits a message indicating the bandwidth allocation of the downlink to the relay station periodically after it has received the acknowledgement header for indicating the downlink bandwidth that the base station initiatively allocates to the relay station, and the relay station transmits broadcast messages to a terminal or a lower relay station in the downlink bandwidth.
