Abstract: Techniques are provide for calibrating device timelines for use in passive positioning of user equipment (UE). An example method for passive positioning of a user equipment includes receiving a first positioning reference signal from a first device at a first time, receiving a second positioning reference signal from a second device at a second time, receiving a timeline difference value associated with the first device and the second device, 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 timeline difference value.

Abstract: In an aspect, a UE receives first positioning assistance data (AD). The UE transmits an indication to a network component (e.g., BS, core network component, LMF, etc.) that the UE has received the first positioning AD. The network component determines second positioning AD that is based at least in part upon the first positioning AD. The network component transmits the second positioning AD to the UE.

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.

Abstract: In an embodiment, a serving BS of a UE may transmit a PDCCH communication to the UE. The PDCCH communication triggers a partial RACH procedure, whereby a RACH transmission is performed. In some designs, the RACH transmission is for positioning, and positioning measurements are performed at the serving BS and (optionally) at one or more non-serving BSs. In some designs, measurement data based on the positioning measurements are conveyed to a position estimation entity (e.g., LMF), which performs a positioning estimate of the UE.
