    • The present disclosure relates to methods and devices for mitigating inter-cluster interference in clusters where one or more network nodes are transmitting in coordination using several transceiver antennas. In particular the disclosure relates to improved precoder algorithms to be used for coordinated multipoint transmission applications. The disclosure also relates to corresponding computer programs. The disclosure proposes a method, performed in a coordination unit in a communication system, of mitigating inter-cluster interference, wherein the coordination unit is configured to coordinate transmissions in a cluster comprising one or more wireless devices and one or more network nodes, wherein the one or more network nodes are transmitting in coordination to the wireless devices in the cluster using several transceiver antennas. The method comprises receiving S2, for each transceiver antenna in each of the one or more network nodes 110a, a signal comprising pre-defined sounding sequences transmitted by the one or more wireless devices of the cluster and sounding channel interference from one or more wireless devices outside the cluster. The method further comprises estimating S4, from the received signal, the sounding channel interference from the wireless devices outside the cluster. The method also comprises determining S5 downlink precoder weights, for use when transmitting from the transceiver antennas of the cluster, using the estimated sounding channel interference from the one or more wireless devices outside the cluster.

    • Enhanced digital broadcast signals are transmitted on a digital radio broadcast signal by allocating spectral resources of the digital radio broadcast signal to simultaneously serve existing receivers (which can decode default content but not new content from the enhanced digital broadcast signal) and new receivers (which can decode default content and can decode new digital content from the enhanced digital broadcast signal) by modulating a first plurality of reference subcarriers with a first signal constellation, and modulating a second plurality of reference subcarriers with a second modified signal constellation such that a receiver processes the digital radio broadcast signal to produce a first coherent reference signal estimate for the first plurality of reference subcarriers to extract the default content for playback and to produce a second coherent reference signal estimate for the second plurality of reference subcarriers to disregard the new content.
