Method and apparatus for implementing ascending frequency-hopping transmission in TDD system

The invention discloses a method for implementing uplink frequency-hopping transmission in a TDD (Time Division Duplex) system. The method includes: a network side is provided with a composing structure of Transmission Time Interval (TTI) so as to contain one or more than one subframe; the network side sets the frequency-hopping mode adopting the TTI for uplink transmission; the network side informs a terminal side about the composing structure of the TTI and the frequency-hopping mode, and the terminal side carries out frequency-hopping transmission of uplink data according to the composing structure of the TTI and the frequency-hopping mode. The embodiment of the invention sets the composing structure of the TTI to contain one or more than one subframe by the network side and sets the frequency-hopping mode adopting the TTI for uplink transmission; the network side informs the terminal side about the composing structure of the TTI and the frequency-hopping mode. The terminal side carries out uplink data transmission according to the composing structure of the TTI and the frequency-hopping mode, thereby implementing flexible uplink frequency-hopping transmission mode, reducing mutual interference when the terminal carries out uplink communication in the system, and improving the system communication quality.
