Abstract: The devices, systems, and methods discussed herein involve abase station (e.g., gNB) that employs a broadcast technology such as the Multimedia Broadcast Multicast Service (MBMS) to relay hidden-node information to the neighboring UE devices. In some examples, a base station receives at least one report based on data acquired by at least one non-communication sensor of a user equipment (UE) device. Based on the at least one report, the base station transmits a message to another UE device that results in the other UE device refraining from using communication resources that will interfere with transmissions by other UE devices.

Abstract: An eNodeB transmits a high priority indicator within a licensed frequency band. In response to receiving the high priority indicator, other eNodeBs refrain from transmitting signals within an unlicensed frequency band. After determining that no other eNodeBs are transmitting signals within the unlicensed frequency band, the eNodeB transmitting the high priority indicator transmits signals to a user equipment (UE) device.

Abstract: A base station (eNB) determines device-to-device (D2D) transmission parameters for signal transmission over a D2D communication link between a first user equipment (UE) device and a second UE device. The eNB instructs the first UE device to transmit a reference signal that is received by the second UE device. The second UE device reports D2D channel characteristic information indicative of the received reference signal. Based on the D2D channel characteristic information, the base station determines the D2D transmission parameters and provides the parameters to the first UE device.

Abstract: A remote user equipment (UE) device transmits a coverage indicator to a relay UE device served by a first cell where the coverage indicator at least indicates that the remote UE device is in coverage of a second cell. The coverage indicator may include other information such as a frequency used by the second cell, a cell identifier of the second cell, bandwidth combination capability of the remote UE device, and/or a sidelink (SL) discovery pool of the second cell.
