DATA TRANSMISSION METHOD FOR HYBRID AUTOMATIC RE- TRANSMISSION REQUEST SYSTEM 2/3 IN WIDE BAND RADIO COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To reduce complicated hardware of the physical channel of a transmitting part by using two logic channels and one physical channel at the time of realizing a hybrid automatic re-transmission request system 2/3 for an efficient packet data service in a radio communication system. SOLUTION: This data transmission method at the time of applying a hybrid automatic re-transmission request system 2/3 for efficient data transmission in a radio communication system comprises a step for generating data and additional information in the RLC hierarchy of the radio network and transmitting them through a logic channel to the MAC-D when an MAC-C for processing a shared channel part in an MAC hierarchy and an MAC-D for processing a general user part are separated from each other, and allowed to exist in different radio networks, a step for transmitting the data and the additional information from the MAC-D through a transmission channel to a base station, and a step for processing the data and the additional information into a radio transmission configuration, and multiplexing and transmitting it through a physical channel to the mobile station.
