    Abstract: To configure a UT for handover between a source evolved Node-B (eNB) and a target eNB using aerial communications in a cellular network, the UE processing circuitry is to decode measurement configuration information from the source eNB. The measurement configuration information includes a plurality of height thresholds associated with aerial height of the UE. A measurement report is encoded for transmission to the source eNB. The measurement report includes the aerial height of the UE and the measurement report generation triggered based on one or more triggering events associated with the plurality of height thresholds. RRC signaling from the source eNB is decoded, the RRC signaling including a handover command. The handover command is based on a handover decision by the source eNB using the measurement report. A handover from the source eNB to the target eNB is performed based on the handover command.

    Abstract: Systems and methods to encode and/or decode structured super-position coding to enhance control channel capacity are disclosed herein. User equipment (UE) may be configured to communicatively couple to an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) Node B (eNB). A first UE and a second UE may be coupled to the eNB. Basic PDCCH may be sent to the second UE, and extra PDCCH may be sent to the first UE on the same time-frequency resource. The second UE may be able to decode the basic PDCCH as it normally does. The first UE may be able to decode the basic PDCCH for the second UE, cancel the basic PDCCH from the signal, and decode the extra PDCCH. The extra PDCCH may be restricted to certain positions relative to the basic PDCCH to simplify searching by the first UE.

    Abstract: A method for self-interference cancellation in a wireless communication device. The wireless communication device has an estimator, a transmitter and a cancellation device. The estimator is configured to estimate a known signal received from a second wireless communication device when the second wireless communication device is utilized less than a predetermined threshold. The transmitter is configured to transmit within a coherence time of the estimated known signal, a predetermined signal. The cancellation device is configured to cancel the estimated known signal from a received signal.

    Abstract: Described are methods and devices for enabling D2D communications with signal structures that require minimal changes to the current LTE architecture. In the embodiments described, the eNB grants resources to UEs for D2D communication and either initiates or permits a pair of UEs to establish a D2D link. Certain embodiments are designed to minimize changes to the current LTE control signaling structure by having the control signaling always come from the eNB as in a normal cellular link so that the transmitting UE transmits over a data channel (e.g., PUSCH/PDSCH) that the receiving UE is able to decode.

    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.
