Title: FRONTHAUL TRANSMISSION
Abstract:
The amount of data transmitted on a fronthaul connection between a radio equipment, RE and a radio equipment controller, REC may be reduced by transferring a signal received by the RE on a first antenna and for a signal received on a second antenna transferring a deviation from a determined relationship between signals on the first antenna and signals on the second antenna. The signal received by the RE on the second antenna is reconstructed in the REC based on the signal received by the RE on the first antenna, the relationship and the deviation.
