Abstract: A base station in a wireless network receives, from a UE in the wireless network, a message indicating the UE requests a gap for the UE to perform self-calibration of full-duplex communication. The base station determines the gap for the UE to use to perform the self-calibration of full duplex communication and sends indication of the gap toward the user equipment. The UE sends a message indicating the UE requests a gap in order for the UE to perform self-calibration of full duplex calibration. The UE receives, from the base station, indication of the gap. The UE performs the self-calibration of full duplex calibration using the gap.

Abstract: Various example embodiments provide a system for mitigating effects of a power back-off due to exposure of user's body to transmitted power. A user equipment (UE) may determine triggering of a power exposure event, for example a body of a user coming close enough to trigger a maximum permissible exposure (MPE) limit. The UE may then send an emergency signal including an indication of the triggered power exposure event to a base station. Various beneficial options for rapidly providing the emergency signal are disclosed. The UE and the base station may enter an emergency mode, where the UE may provide further information on its power back-off conditions. Based on the information received from the UE, the base station may determine to perform adaptation of the radio link to avoid radio link failure. Apparatuses, methods, and computer programs are disclosed.

Abstract: In a system, apparatus, method, and non-transitory computer readable medium related to an authentication relay procedure for passive Internet of Things (IoT) devices, a network node may be caused to receive a first transmission signal from at least one IoT device in response to a first activation signal transmitted by an activator node, determine an authentication test condition based on the received first transmission signal, and transmit a request to the activator node based on the determined authentication test condition, the request enabling the activator node to transmit a second activation signal generated based on the determined authentication test condition.

Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable media for adaptive configuration of multistatic harmonic tag backscatter. A network device transmits, to an illuminator for a passive tag, a request for transmitting an activation signal to a passive tag at a primary frequency and a first transmission power. The network device receives, from the illuminator, information about a harmonic frequency of a harmonic of the activation signal back-scattered from the passive tag, a received level of the harmonic and a distance between the illuminator and the passive tag. The network device selects at least one reader for the passive tag. The network device configures the illuminator to transmit the activation signal to the passive tag at the primary frequency. The network device configures the at least one reader to receive the harmonic of the activation signal at the harmonic frequency.
