Abstract

Embodiments of the present disclosure relate to data transmission in a wireless communication system. In an embodiment of the present disclosure, there are provided 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.

Description

technical field [0001] Embodiments of the present disclosure generally relate to wireless communication technologies, and more particularly relate to methods and devices for data transmission in wireless communication systems. Background technique [0002] With the continuous increase of mobile data services, the 3rd Generation Partnership Project (3GPP) organization has formulated the Long Term Evolution (LTE) specification and the LTE-Advanced (LTE-A) specification. As a next-generation cellular communication standard, an LTE or LTE-A system may operate in a frequency division duplex (FDD) mode and a time division duplex (TDD) mode. [0003] Machine-to-machine (M2M) communication, also called machine-type communication (MTC), is an emerging communication mode. It refers to the communication between computers, embedded processors, smart sensors, actuators and mobile devices without or with limited human intervention, and it is used in many applications such as in extreme o...
