Abstract
The present invention is directed to provide a relay method in a wireless access system, including comprising the following steps: in downlink direction, receiving downlink data from a base station, wherein the downlink data include control information for relay operation; constructing downlink data to be retransmitted; retransmitting the constructed downlink data to wireless communication terminals according to a profile specified by the control information; and, in uplink direction, receiving uplink data from the wireless communication terminals according to a profile specified by the control information; recovering the uplink data of the wireless communication terminals; and retransmitting the uplink data to the base station according to the profile specified by the control information. The present invention further provides the corresponding base station device, relay device and wireless relay system. Through the present invention, the base station is able to perform centralized control of the entire mobile multi-hop relay system, which effectively reduces the complexity of the relay device and can realize a transparent transportation with respect to wireless communication term…
