Abstract: A technique for assessing connection quality in a wireless communication network is disclosed. A method implementation of the technique includes obtaining a radio frequency, RF, channel response measurement indicative of a channel gain in time and frequency observed at a location covered by the wireless communication network, and determining, based on the RF channel response measurement, an estimated connection quality at the location using a machine learning model trained to map RF channel response measurement based features to corresponding connection qualities.

Abstract: A method, network node and wireless device (WD) for efficient wake up signal provisioning for WDs in discontinuous reception are disclosed. According to one aspect, a method includes at a first paging occasion (PO) in which the network node transmits paging-related downlink control information to a first group of WDs, multiplexing paging indicators related to one or more POs to be monitored by a WD belonging to a second group of WDs.

Abstract: Embodiments of the present disclosure provide methods and apparatus for scatterer localization and material identification. The method performed by an identification apparatus may comprise: determining (S101) a reflection loss of a power of a wireless signal caused by a reflection at an object, for the purpose of identifying a material of the object and localizing a position of the object. The method performed by a reception apparatus may comprise: receiving (S201) a wireless signal transmitted from a transmission apparatus and reflected by an object; and transmitting (S202), to an identification apparatus, information about the wireless signal. The method performed by a transmission apparatus may comprise: receiving (S301) an indication for identifying a material of an object; and transmitting (S302) a wireless signal reflected by the object to a reception apparatus.

Abstract: The disclosure relates to a method, device and non-transitory computer readable media or selecting a transmit power, a physical resource block (PRB), and a modulation and coding scheme (MCS) for a grant free uplink transmission. The method comprises obtaining an observation of the radio environment of the device. The method comprises selecting an action, based on the observation, for execution during a next time slot, the action comprising selecting the transmit power, the PRB, and the MCS for the grant free uplink transmission.
