The present disclosure provides a method (200) in a network device for data transmission over a front haul interface between a first unit and a second unit. The method (200) includes: compressing (210), at the first unit, time domain data in frequency domain and/or spatial domain; transmitting (220) the compressed time domain data along with an associated compression parameter over the front haul interface from the first unit to the second unit; and decompressing (230), at the second unit, the compressed time domain data based on the compression parameter.
