The data transmission and related methods in non-transparent centralized scheduling multi-hop relay network

摘要

Published related methods and data transmission in a non-transparent centralized scheduling multi-hop relay network, problems that can not come injection depression data is avoided, the present invention is enhanced performance and quality of service and. In the transmission method, when data is transmitted from the base station, is written Allocation Reference Information Element IE in the mapping message MAP, and is used for position indication of the media access control layer protocol data unit MAC PDU waiting for transmission . After receiving the mapping message MAP transmitted from the relay station or another, are transmitted from the base station, on the basis of an instruction of the Allocation Reference IE in this, to obtain the MAC PDU, the lower relay station acquired After re-combination of the MAC PDU, it is transmitted to the bottom were placed into the bandwidth of the base station the base station assigned to it.
