Abstract

A Method and a System for lossless compression and decompression of baseband digital signals in distributed LTE-Advanced (LTE-A) radio access networks The method comprising at least one Remote Radio Head with a plurality of transmit and receive antennas connected to at least one Baseband Unit through a wired connection denoted as fronthaul link. In order to perform said lossless compression and decompression of a plurality of LTE-A baseband digital signals the method uses two additional processing nodes hosted at both ends of said fronthaul link in both an uplink direction and a downlink direction; transforms for both of said uplink and downlink directions said plurality of LTE-A baseband digital signals into frequency domain; and sends through said fronthaul link information corresponding to a set of resource blocks occupied with said plurality of LTE-A baseband digital signals. The system of the invention is adapted to implement the method of the invention.
