Abstract
A method, in a heterogeneous telecommunications network, for mitigating uplink-downlink (UL-DL) interference between a first half-duplex user equipment (UE) operable to communicate using a first frequency resource in an uplink to a first full-duplex node, and a second half duplex UE operable to receive downlink communications from a second full-duplex node, the method including receiving, at the second node, an indication of actual or potential UL-DL interference generated by the first UE, scheduling a pair of UEs, that includes the second UE, for full-duplex UL-DL communication with the second full-duplex node in which DL transmissions to the second UE from the second node use a second frequency resource different from the first frequency resource or in which scheduling is avoided for DL connections to the second UE that fall below a quality of service threshold determined using channel quality measurements obtained by the second UE for the first and second frequency resources.
