Abstract: An interference management scheme may detect a level of uncoordinated interference and compare a detected uncoordinated interference level against an intra-RAT (radio access technology) interference. Intra-RAT interference management algorithms or intra-RAT interference solutions are not triggered/applied if the uncoordinated interference is dominant. Alternatively, intra-RAT interference management algorithms may be triggered if co-channel intra-RAT interference is dominant.

Abstract: Apparatus, methods, and computer-readable media for facilitating a cloud-based vehicle XR user experience are disclosed herein. An example method for wireless communication at a user equipment (UE) includes transmitting a request for a vehicle extended reality (XR) session. The vehicle XR session may be based on a first user XR stream including a vehicle XR component associated with a vehicle and a first user XR component associated with a first user. The first user may have an association with the vehicle. The example method also includes transmitting uplink information associated with the first user XR stream. The example method also includes receiving rendering information associated with the first user XR stream. The rendering information may be based on the uplink information.

Abstract: Various embodiments include methods and devices for training and implementing a tree-based behavior prediction model for use in autonomous vehicle control systems. Some embodiments may include labeling real-world autonomous vehicle run data to indicate an insight of the data, selecting an insight decision tree of the tree-based behavior prediction model for training using the labeled data, training the insight decision tree using the labeled data to classify a probability of an insight associated with the insight decision tree, and updating the tree-based behavior prediction model based on training the insight decision tree. Some embodiments may include selecting an insight decision tree of a tree-based behavior prediction model configured for classifying a probability of an insight associated with the insight decision tree, executing the insight decision tree, and outputting a probability of an insight determined from executing the insight decision tree using the data.

Abstract: Methods and apparatuses are provided for use in wireless communication devices to provide a capability for vehicles to actively perform traffic planning with regard to other vehicles, for example, within a region comprising an intersection and possibly wherein the intersection is not associated with a device or service for such or similar purposes. Such underlying techniques may reduce traffic congestion in certain instances by allowing two or more vehicles to negotiate or otherwise coordinate safe traversal within a region comprising an intersection. Moreover, the traffic planning techniques may be of use for a variety and/or mixture of different types of vehicles, paths, intersections, etc.

Abstract: In an embodiment, an access point executes a Clear Channel Assessment (CCA) protocol to determine whether to begin transmission within a DRS Measurement Timing Configuration (DMTC) window. The access point transmits, based on a result of the execution, a multi-subframe DRS within the DMTC window, the multi-subframe DRS including a plurality of DRS subframes that each includes a plurality of symbols.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may perform a channel access procedure on a shared radio frequency spectrum band using a first beam configuration. The base station may transmit, based at least in part on successful completion of the channel access procedure, a reservation request message (RRQ) to a user equipment (UE) using a second beam configuration, the second beam configuration comprising a beam width that is equal to or narrower than a beam width of the first beam configuration. The base station may receive a reservation response message (RRS) from the UE in response to the RRQ, the RRS comprising a third beam configuration that is based at least in part on the second beam configuration.

Abstract: Techniques for autonomous uplink (AUL) transmissions are provided that allow for efficient use of shared radio frequency spectrum band resources. A user equipment (UE) may determine a duration of an AUL transmission and modify an uplink waveform or provide an indication to a base station of one or more channel resources that may be available for base station transmissions, in order to more fully utilize shared radio frequency spectrum band resources within a maximum channel occupancy time (MCOT). A base station may activate or deactivate AUL transmissions through downlink control information (DCI) transmitted to the UE. A UE and base station may exchange various other control information to provide relatively efficient autonomous uplink transmissions and use of the shared radio frequency spectrum band resources.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may transmit a first signal; listen, after transmitting the first signal and during a listening interval, for a second signal from a user equipment (UE) affected by the first signal, the second signal being indicative of interference at the first UE; receive the second signal during the listening interval; and initiate an interference management procedure based on receipt of the second signal.
