    Abstract: A method of wireless communication performed by a first transmission device incudes receiving a first set of observations from a first receiving device based on transmissions from the first transmission device to the first receiving device at a previous time slot of a fixed contention-based spectrum sharing system. The first transmission device shares a spectrum with a second transmission device. The method also includes measuring an energy level from an ongoing data transmission of the second transmission device at a current time slot. The method further includes generating, at an artificial neural network of the first transmission device, at least one of a transmission determination, a set of transmission parameters, or a combination thereof, based on a second set of observations, the energy level, and a counter. The method also includes transmitting, to the first receiving device, during the current time slot based on at least one of the transmission determination, the set of transmission parameters, or the combination thereof.

    Abstract: Position determination of a user equipment (UE) is supported using channel measurements obtained for Wireless Access Points (WAPs), wherein the channel measurements are for Line of Sight (LOS) and Non-LOS (NLOS) signals. Based on WAP almanac information and the channel measurements, channel parameters indicative of positions of signal sources relative to a first position of a UE may be determined. Using the first position of the UE and an association of the signal sources with corresponding channel parameters, a second position of the UE may be determined. The position of the UE may be a probability density function. Additionally, position information for signal sources may be determined, such as a probability density function, as well as signal blockage probability and an antenna geometry and the WAP almanac information may be updated accordingly.

    Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) receives one or more positioning reference signals from a first transmission-reception point (TRP) involved in a positioning session with the UE, detects whether or not there is a positioning bias event associated with the first TRP based on one or more parameters related to the one or more positioning reference signals, the positioning bias event affecting an accuracy of a location estimate of the UE, and transmits, in response to the detection that there is a positioning bias event, a report of the positioning bias event to a network node. Upon receiving the report, the network node performs one or more corrective actions to address the positioning bias event.

    Abstract: Aspects relate to dynamically modifying channel state information (CSI) settings, such as CSI report settings and/or CSI resource settings, utilized by a user equipment (UE) in reporting CSI to a base station. For example, a UE may identify at least one parameter associated with a CSI setting and provide a recommendation to modify the CSI setting based on the at least one parameter to a base station. The recommendation may include, for example, an optimized configuration of the CSI setting or soft output, such as an uncertainty level or confidence level associated with the CSI setting. The base station may then select the optimized CSI setting based on the recommendation and provide the optimized CSI setting to the UE for use in generating and transmitting CSI reports to the base station. Other aspects, features, and embodiments are also claimed and described.

    Abstract: Techniques are provide for passive positioning of user equipment (UE) with analog beamforming. An example method for positioning a user equipment includes receiving a first positioning reference signal from a first base station at a first time, receiving a first timing difference value based on two or more positioning reference signals transmitted from the first base station, receiving a second positioning reference signal from a second base station at a second time, receiving a second timing difference value based on two or more positioning reference signals transmitted from the second base station, and determining a time difference of arrival between the first positioning reference signal and the second positioning reference signal based at least in part on the first timing difference value and the second timing difference value.
