Method and apparatus for facilitating data transmission
A method performed by a first wireless communication system operating on a first subframe structure in an unlicensed spectrum is disclosed. The method comprises determining a subframe timing difference between the first wireless communication system and a second wireless communication system operating on a second subframe structure in the unlicensed spectrum and determining whether timing difference exists between the first and second wireless communication systems based on the subframe timing difference. The method further comprises adjusting a subframe timing of the first wireless communication system, in response to determining the existence of the timing difference, to obtain a channel on an unlicensed carrier in the unlicensed spectrum for data communication by the first wireless communication system.
