Abstract: Systems, methods, apparatuses, and computer program products for asset tracking joint sounding reference signal (SRS) transmission. A location management network node may send a positioning failure message to a serving network node. The serving network node may group devices if one or more criteria are met. When one or more of the devices can be grouped, the serving network node may assign and distribute, to devices, a multi-tag-SRS sequence identifier that may be used by the devices in the group. The serving network node may compute and send, to the devices in the group, a multi-tag-SRS transmit configuration. The devices may perform a joint SRS transmission. The location management network node may compute a location of a centroid for the group of devices associated with the reported metric.

Abstract: An apparatus may include circuitry configured for providing first data indicative of a first relative angle-of-arrival measurement between a first base station and a second base station, from the position of a user device, based on angle-of-arrival measurements. The apparatus may also include circuitry configured for providing second data indicative of first and second angle-of-departure measurements, each measurement indicative of an angle between the user device and the other base station of the first set of base stations from the position of the respective first and second base stations based on a plurality of beams transmitted from the respective base station to the user device. The apparatus may also include circuitry configured for determining a beam directionality error associated with at least one of the first and second base stations based on the first relative angle-of-arrival measurement and the first and second angle-of-departure measurements.

Abstract: Example embodiments relate to machine learning based digital pre-distortion for power amplifiers. A device may amplify a signal with a power amplifier and transmit the signal. The signal may be received by an internal feedback receiver of the device. The device may further comprise a first machine learning model configured to emulate an external feedback receiver and to generate an emulated feedback signal based on the internal feedback signal. The device may further comprise a second machine learning model configured to determine digital pre-distortion parameters for the power amplifier based on the emulated feedback signal. Apparatuses, methods, and computer programs are disclosed.

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).
