MULTI-HOP WIRELESS RELAY COMMUNICATION SYSTEM AND DOWNLINK DATA TRANSMITTING METHOD AND DEVICE THEREOF

摘要

A downlink data transmitting method applied in the multi-hop wireless relay communication system, the method includes: a network unit obtaining the identifier of the next hop network unit corresponding to the connection identifier in the downlink MPDU packet head based on the corresponding relationship of the stored connection identifier and the identifier of next hop network unit, and transmitting the downlink MPDU to the next network unit using the obtained identifier of it, therefore the data transmission of multi-hop wireless communication system could be realized, and the current user terminal and protocol structure of the core network do not need to be changed. Meanwhile a multi-hop wireless relay system and the base station, relay station in the system are disclosed.
