METHOD FOR TRANSMITTING DATA USING FREQUENCY HOPPING AND METHOD FOR DETERMINING A SUB-BAND FOR FREQUENCY HOPPING

摘要

A method for transmitting data by using the frequency hopping and a method for determining a sub-band for the frequency hopping are provided to determine a basic block for performing the next transmission according the specific rule, thereby reducing the scheduling information amount. When the re-transmission period is 3 TTI(Transmission Time Interval), the total three re-transmission groups of the first to three re-transmission groups are constructed. The system band for transmitting the up-link data packet includes four sub-bands comprising the same bandwidth. An index is allocated at each sub band and the first and fourth sub-bands are formed. All sub-bands of the specific re-transmission group are designated as the sub-band for applying the frequency hopping manner. The first to fourth sub-bands are designated as the frequency hopping sub-bands. All sub-bands of any one between the second and third re-transmission groups are also designated as the frequency hopping sub-bands as well as the first re-transmission group.
