METHOD AND APPARATUS FOR DATA TRANSMISSION IN A WIRELESS COMMUNICATION SYSTEM

Embodiments of the present disclosure relate to data transmission in a wireless communication system. Provided is a method and apparatus of data transmission in a wireless communication system. The method comprises receiving information on assigned resources for the data transmission; and determining resources for respective data retransmissions based on the information on the assigned resources for the data transmission and a predetermined frequency hopping pattern. Particularly, a plurality of symbols are used to perform a radio frequency (RF) retuning and a time duration of the plurality of symbols is at least equal to a time interval required by the RF retuning. With embodiments of the present disclosure, there is provided a new solution for data transmission in which the RF retuning can be performed in a plurality of symbols, which might obtain the frequency diversity and at the same time can reduce transmission mistakes and improve the transmission efficiency.
