Abstract (en)
[origin: WO2019050544A1] Devices and methods for interference mitigation in a full duplex cellular system are generally described. An eNB can include processing circuitry configured to, in response to a request for interference information, determine an UL interference indicator. The UL interference indicator quantifies eNB-to-eNB interference resulting from DL traffic sent from one or more neighboring eNBs and UE-to-eNB interference resulting from UL traffic sent to the eNB, the DL traffic and the UL traffic using overlapping time and frequency resources. The processing circuitry can further decode a parameter update request, which includes a power boosting factor. The power boosting factor is selected based on a ratio of the UE-to-eNB interference and the eNB-to-eNB interference. The power boosting factor is encoded for transmission to one or more UEs within a cell of the eNB, the power boosting factor indicating a power level adjustment in the transmit power of the one or more UEs.
