Abstract: A method includes confirming, by a user device with a network node, a set of machine learning (ML) functionality adaptation parameters for the user device to perform adaptation of a ML functionality associated with at least one ML model that is used by the user device to perform a radio access network (RAN)-related function. The set of ML functionality adaptation parameters indicate at least one adaptation cycle during which the user device is to perform the ML functionality adaptation and a validity period for which the set of ML functionality adaptation parameters are valid. The method also includes performing, by the user device, adaptation of the ML functionality during the at least one adaptation cycle.

Abstract: An apparatus, method and computer program is disclosed relating to positioning. For example, the apparatus may comprise means for operating the apparatus in a first operating state of a plurality of predetermined operating states as part of a positioning process involving communications with one or more remote nodes. The apparatus may also comprise means for identifying one or more trigger events and means for selecting a different one of the operating states, based at least on: the first operating state, and the presence or absence of one or more trigger events. The apparatus may transition from the first operating state to the selected different operating state, wherein the plurality of predetermined operating states may comprise a target state, an anchor state, a positioning reference unit (PRU) state, and a standby state.

Abstract: Systems, methods, apparatuses, and computer program products for GIS-NR beamforming for mmWave. For example, certain embodiments may provide for beam realignment, through which a serving network node may be able to re-position its beam towards a UE without the UE explicitly measuring and signalling to the network node the need for realignment. Instead of performing the traditional UE-based exhaustive beam search, the serving network node may proactively switch the beam in an attempt to track the UE movements. The serving network node may do this by corroborating information from two types of sources: 1) a set of neighbor mobile or fixed network nodes and 2) a geographic information system (GIS).

Abstract: Improved techniques of UE local and network assisted compensation of the UE PCO impact on positioning reference signal include performing compensation of positioning measurement error by transmitting a reference signal to a proximate reference device. In some implementations, the reference signal is a wideband reference signal, and the compensation is over a wide band of frequencies. In some implementations, the positioning measurement error includes a PCO in-band variation (IBV). In such an implementation, the UE may associate a respective compensation over the wide band of frequencies with an antenna panel and/or an angle with respect to the proximate reference device (RD).

Abstract: In order to perform small data transmission during an RRC INACTIVE mode, a UE may need to determine whether the stored timing advance (TA) is valid. A TA may be valid if its usage would result in an uplink transmission arriving at a TRP of a base station during a time period during which the base station expects to receive uplink transmission. A UE may determine that a TA is valid based on a received fraction of the length of a cyclic prefix and observed SSB time shift.

Abstract: To increase positioning accuracy, channel characteristics are determined taking into account receive filter response and transmit filter response. For example, upon receiving assistance data for positioning an apparatus, a transmit sequence is generated using the assistance data; and a combination of the transmit sequence is generated by combining the transmit sequence. Further, a receive filter response is determined, a transmit filter response is obtained, and a combined filter response is generated using the receive filter response and the transmit filter response. Reference signals received over a channel are measured by sampling them into a plurality of time-domain samples, and the channel is estimated from the plurality of time-domain samples using the combined filter response and the combination of the transmit sequence. Then, per channel characteristics, a value of the channel characteristics based on the channel estimated is determined.
