Abstract: A wireless communication system employs DNNs or other neural networks to provide for RAT-assisted positioning of UEs. A TX DNN at the BS generates and provides for wireless transmission of a reference signal to the UE. An RX DNN at the UE receives the reference signal and local UE sensor data as input, and from this input generates a UE measurement and sensor report. A TX DNN at the UE receives the report as an input, and from this input generates an RF signal representing the UE measurement and sensor report for transmission to the BS. An RX DNN at the BS receives the report from the RF signal as input, and from this input generates a position estimate of the UE.

Abstract: This disclosure provides systems, methods, and apparatuses for managing communications within a first coverage area of a non-terrestrial network (NTN) node implementing a first radio access technology (RAT) when the first coverage area temporarily overlaps with a second coverage area of a terrestrial network (TN) base station implementing a second RAT. The NTN node and the TN base station can implement dynamic spectrum sharing (DSS) to dynamically allocate spectrum between the NTN node (of the first RAT) and the TN base station (of the second RAT) based, at least in part, on configuration information received from the TN base station and on the overlap between the first and second coverage areas.

Abstract: This disclosure provides systems, methods, and apparatuses for managing communications and controlling power in a subset (119) of a user equipment coordination set (UECS) (117) in a wireless communication system. According to aspects of the disclosure, a coordinating user equipment (UE) (110A) of the UECS selects (506, 606, 904) a subset (119) of the UEs of the UECS for joint transmission or joint reception of signals to or from the network entity, respectively. The coordinating UE determines the subset of the UEs of the UECS based on various UE conditions, such as reference signal received power (RSRP), specific absorption rate (SAR), battery condition, thermal condition, location of the UE, UE power class, or other factors. The coordinating UE allocates power and sends (604A, 604B, 604C) power control commands to the individual UEs in the subset of UEs in the UECS.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for network slicing of non-terrestrial traffic in a wireless communication system. A User Equipment (UE) receives a non-terrestrial network (NTN) slicing policy rule, the NTN slicing policy rule including one or more NTN-based conditions for the UE to access a network slice through an associated NTN node. The NTN node receives, from the UE, a request to access the network slice through the NTN node and transfers, to the UE, an acceptance of the request to access the network slice through the NTN node.

Abstract: This disclosure provides devices, methods, and systems for radar sensing using adaptive phase-changing devices (APDs). An example device (e.g., a base station, a user equipment, a satellite network entity, etc.) first transmits (340) initial radar signals in multiple directions to identify a blocking object. Based on the identified position of the blocking object, the device may employ (366) an APD (e.g., based on its registered position) that helps routing signals around the at least one blocking object (such as an APD positioned to reflect the radio waves from the device to reach behind the blocking object). The device has the APD vary (377) phase vectors to change reflection directions of APD radar sensing signals to scan for a blocked object blocked by the blocking object. When the device finds a blocked object, the device determines (386) a set of APD configurations for a signal path specific to the blocked object.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, that perform per antenna power control in a user equipment (UE 110). A base station (108) transmits a message indicating desired power levels for each individual antenna port. The base station can transmit desired power levels for individual antenna ports for physical uplink shared channel (PUSCH), physical uplink control channel (PUCCH), and sounding reference signal (SRS) communication. The UE can determine path loss values on an individual antenna port (203) basis. Further, the UE can transmit power headroom reports (PHRs 122) for each individual antenna port. The base station can update transmit power for individual antenna ports by issuing Transmit Power Control (TPC) commands (120) indicating to the UE changes (for example, delta values) in transmission power on a per antenna port basis.

Abstract: A user-equipment-coordination set in a cellular network includes multiple UEs for performing coordinated radar sensing. A first UE determines a configuration to coordinate other UEs to detect an object. The first UE uses the configuration to configure a second UE to transmit a first radar signal and a third UE to detect the first radar signal. The first UE receives first radar signal samples from the third UE based on the third UE receiving the first radar signal in multiple reflection states. The first UE filters the first radar signal samples to remove samples associated with interference from the first radar signal received in a first reflection state. The first UE determines object location information based on at least the filtered first radar signal samples.

Abstract: User equipment proximately located with two base stations operating using different radio access technologies determines whether to enable or disable rate matching of transmissions from its supporting base station. If rate matching is enabled, the user equipment receives transmissions from one of the base stations that avoids time-frequency resources used by the other base station to carry control signals. If rate matching is disabled, the user equipment receives transmissions from the one base station in the same time-frequency resources used by the other base station to carry control signals.

The first base station transmits, via a radio interface to the second base station, a configuration for concurrent communication between the UE and a group of base stations including the first base station and the second base station. The first base station communicates, by processing hardware, data over the radio interface directly with the UE, and via the radio interface and the second base station.

Abstract: A non-terrestrial, wireless communications network (NTN) can assist User Equipments (UEs) in tracking beams generated by NTN base stations for reselection purposes. The NTN determines one or more candidate beams to which the UE can reselect (e.g., while the UE is in an inactive or idle state with respect to controlling radio resources) based on a geographical location of the UE and respective existing and/or predicted non-terrestrial locations of one or more non-terrestrial base stations of the NTN. The NTN transmits an indication of the one or more candidate beams to the UE (and optionally other beam-related information, such as radio access resources and relative priorities), and the UE can reselect a subsequent beam based on the indication received from the NTN. The UE can locally store a mapping of candidate reselection beams to geographical locations for ease and efficiency of future reselections.

Abstract: Techniques and apparatuses are described for enhanced uplink spectrum sharing. A base station communicates, to a user equipment (UE) an air interface resource configuration for a second air interface resource allocated to a second cell that uses a second radio access technology (RAT) and implemented by the base station. The base station receives a first air interface resource configuration for a first air interface resource allocated to a first cell that uses a first RAT, where the first air interface resource configuration differs from the second air interface resource configuration. In aspects, the base station communicates the first air interface resource configuration to the UE. Based on receiving a low-utilization indication for the first air interface resource, the base station directs the UE to utilize the first air interface resource for transmitting uplink communications using the second RAT.
