INTERFERENCE MITIGATION THROUGH SILENCING SIGNALS IN SHARED RADIO FREQUENCY SPECTRUM

Abstract:

Methods, systems, and devices for wireless communications are described for silencing signal transmissions by a user equipment (UE). Silencing signals may be transmitted periodically during shared spectrum downlink communications from a serving base station to the UE to prevent an interfering node from passing a listen before talk (LBT) procedure. The silencing signal transmissions may be configured by the base station and enabled in cases where potential interfering nodes are detected. An interfering node may be notified that silencing signals are being used, and may adjust a periodicity or wait time of its LBT procedures based on the silencing signal periodicity.
