MITIGATING UL-TO-DL INTERFERENCE

摘要

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.

1. A method, in a heterogeneous telecommunications network, for mitigating uplink-downlink interference between a first user equipment, UE, operable to communicate using a first frequency resource in an uplink to a first node operable to transmit and receive using the same frequency resources at the same time so as to provide full-duplex communication, the first UE forming one half of a first pair of UEs, the other UE of the first pair operable to communicate using the first frequency resource in a downlink with the first node at the same time as the first UE communicates in the uplink using the first frequency resource, and a second UE operable to receive downlink communications from a second node operable to transmit and receive using the same frequency resources at the same time so as to provide full-duplex communication, the method including:
receiving, at the second node, an indication of actual or potential UL-DL interference generated by the first UE; scheduling a second pair of UEs, that includes the second UE, for full-duplex UL-DL communication with the second node, the UEs of the second pair operable to send and receive data in an uplink and downlink with the second node at the same time, 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.
