The present invention relates to a network device (1) for joint decoding of received signals in a cellular wireless communication system (50) comprising a plurality of spatially distributed base stations (10) interconnected to said network device (1) by means of at least one backhaul interface having a round-trip delay being larger than a transmission interval for a HARQ cycle of a HARQ algorithm employed by the cellular wireless communication system (50), said network device (1) comprising a processor ( ) adapted to: receive a plurality of baseband signals (BBSs) corresponding to uplink signals received by said plurality of base stations (10) in uplink radio links, said uplink signals being associated with an uplink transmission (ULT) from a user device (20); and decode said uplink transmission (ULT) from said user device (20) by combining said plurality of baseband signals (BBSs).
