Abstract: A network device and UEs are described, which support preemption of a transmission over a first link and provides to a first UE preemption information indicative of a first spatial filter that is to be preempted by the first UE for transmission over the first link. A second UE receives an indication from a network device to: perform a measurement of a reference signal on at least one second spatial filter, or transmit a reference signal on at least one second spatial filter; receive the reference signal from another UE and perform the measurement on the at least one second spatial filter, or transmit the reference signal to another UE on the at least one second spatial filter, according to the indication received from the network device; wherein the at least one second spatial filter is allocated by the UE for receiving over a second link.

Abstract: A transmitting device includes a plurality of antenna ports. Each antenna port is configured to transmit signals and is arranged at a different location, and each antenna port is assigned, depending on its location, a unique resource from a set of resources for signal transmission. Further, a receiving device, preferably on a vehicle, includes at least one antenna element configured to receive signals, and at least one processor configured to determine position and/or orientation information of the transmitting device of a received signal based on a resource from the set of resources for signal transmission.

Abstract: The disclosure relates to a processing device for interference-aware beam pair selection, in particular a processing device in a transmit-receive point, wherein the processing device is configured to select a beam pair from a set of candidate beam pairs (i, j), for setting up a communication link from a serving transmit device to a receive device via the selected beam pair, wherein each of the candidate beam pairs comprises a transmit beam j of the serving transmit device and a receive beam i of the receive device, wherein the selection is based on statistics of a usage of one or more interfering transmit beams (m, k) of one or more interfering transmit devices m.

Abstract: The present disclosure relates to a network device, in particular a User Equipment (UE) or a base station (BS), of a group of network devices involved in a cooperative passive positioning (CPP) operation comprising at least two network devices for detecting and positioning at least one target object. One example network device is configured to apply an operation mode from one or more of: initiating network device for initiating a CPP measurement, transmitting network device for transmitting a radio signal to scan for an environment of the network device, receiving network device for receiving a reflection signal based on a reflection of the radio signal from the at least one target object, and data fusion network device for detecting and positioning the at least one target object based on at least one of the reflection signal or a Line-of-Sight (LOS) signal.
