    Abstract: Devices and methods of providing joint scheduling in a full-duplex LTE system are generally described. The UE measures intra-cell interference at the UE caused by a UL transmission from each intra-cell UE, calculates a ratio of the intra-cell interference over an average inter-cell interference, determines whether the intra-cell UE is an aggressor or non-aggressor based on whether the ratio exceeds a threshold, transmits at least some of the determinations to the eNB as feedback, and communicates with the eNB based on a schedule that is dependent on the feedback such that the UE is neither an aggressor nor is subject to interference from aggressors. The schedule may also be based on wideband CQI feedback based on a ratio of an average overall DL interference plus noise over the average inter-cell interference plus noise and/or subband. CQI feedback based on SINR measurements.

    Abstract: Embodiments of interference coordination for aerial vehicle user equipment (UE) are described. In some embodiments, a base station (BS) is configured to select a subset of time-frequency resources dedicated for use in serving aerial vehicle UEs and communicate with the aerial vehicle UEs via the subset of time-frequency resources. In some embodiments, the BS may transmit signaling to a neighbor BS that indicates the BS has dedicated the subset of time-frequency resources for serving aerial vehicle UEs and the subset of time-frequency resources to be used. The BS may receive an indication from the neighbor BS that a neighbor BS is to dedicate the subset of time-frequency resources to serve aerial vehicle UE, and based on the indication, the BS may reduce transmission activities in the subset of time-frequency resources, including refraining from transmitting or reducing an amount of information or power level of signaling to the aerial vehicle UEs.
