Title:
METHOD AND APPARATUS FOR RESOURCE MANAGEMENT IN A RELAY COMMUNICATION SYSTEM, AND METHOD AND APPARATUS FOR DATA RELAY USING SAME
Document Type and Number:
WIPO Patent Application WO/2010/126297
Kind Code:
A2
Abstract:
The present invention relates to a data transmission method for a relay station in a multi-hop relay communication system. The data transmission method of the relay station comprises the steps of: determining a data aggregation scheme for aggregating multiple packet data received from a mobile station and transmitting aggregated data to a base station; receiving the packet data from the mobile station, classifying the packet data into at least one aggregated packet class in accordance with the data aggregation scheme determined in the previous step, and storing the aggregated packet classes; determining the quality of service (QoS) requirements and the modulation and coding scheme (MCS) level of the aggregated packet classes stored in the previous step; calculating the required resources in accordance with the determined MCS level, and making a request at the base station for the allocation of the calculated resources; receiving a resource allocation acknowledgement message from the base station, modulating and coding the aggregated packet classes, and mapping the aggregated packet classes to the allocated resources to construct an aggregated packet; and transmitting the thus-constructed aggregated packet to the base station.
