Abstract: Disclosed are various techniques for wireless communication. In an aspect, a user equipment (UE) transmits, to a serving base station, in one or more active bandwidth parts (BWPs) of the UE, a request for a no-downlink-scheduling gap, the request including at least time-domain parameters related to scheduling the no-downlink-scheduling gap, receives, from a neighboring base station, in the one or more active BWPs, a downlink positioning reference signal (DL-PRS) during the no-downlink-scheduling gap, and transmits, in the one or more active BWPs, an uplink positioning reference signal (UL-PRS) during the no-downlink-scheduling gap in response to reception of the DL-PRS.

Abstract: Disclosed are various techniques for wireless communication. In an aspect, a user equipment (UE) receives, from a network entity, a positioning reference signal (PRS) configuration. The UE receives, from a serving base station, a measurement gap (MG) configuration. The UE determines that one or more transmission properties of one or more resources should be modified and transmits PRS modification information to the network entity based on the one or more transmission properties of one or more PRS resources to be modified. The network entity may be a location server or location management function.

Abstract: A mobile device and base station are enabled to support improved positioning accuracy in the presence of phase noise in high frequency radio network, such as in 5G New Radio network operating in mmWave. Phase Tracking Reference Signal (PTRS) may be transmitted with Positioning Reference Signals (PRS) and used for positioning and/or used to correct the phase offset between symbols in the PRS. A request may be made to transmit PTRS alone or with the PRS, or that the PRS is transmitted with a specific PRS frame structure, e.g., with a specific comb value, that minimizes the impact of phase noise. The PTRS or a phase ramp of the staggered symbols in the PRS may be used to estimate and correct the phase offset. Less than all of the symbols transmitted in the PRS may be used to generate positioning measurements to minimize the impact of phase noise.

Abstract: Aspects of the disclosure are related to a method, apparatus and system for adjusting a processing bandwidth or frequency domain buffer decimation associated with reference signals, for example, positioning reference signals (PRS). By reducing the number of, for example, resource blocks and/or resource elements to be processed, the power involved in processing the reference signal can be reduced. Hence, in some implementations, aspects of the disclosure can enable low-power low-bandwidth devices, such as NarrowBand Internet of Things (IoT) (NBIoT), to decode reference signals such as PRS.

Abstract: In an aspect, a user equipment (UE) may operate in a multi-transmission-reception (multi-TRP) mode. The UE may engage in a positioning session with a network entity while operating in the multi-TRP mode. The UE may report a set of positioning capabilities for the positioning session to the network entity, wherein the set of positioning capabilities indicate one or more enhanced positioning capabilities of the UE to perform positioning operations based on the UE operating in the multi-TRP mode, and wherein the one or more enhanced positioning capabilities are greater than one or more corresponding positioning capabilities of the UE to perform positioning operations based on the UE operating in a single-transmission-reception (S-TRP) mode.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) detects a conflict between a first sidelink reference signal transmission from a first sidelink UE and a second sidelink reference signal transmission from a second sidelink UE, wherein the first sidelink reference signal transmission at least partially overlaps with the second sidelink reference signal transmission in at least one time resource, at least one frequency resource, or both, and transmits a collision report to a third sidelink UE, the collision report including at least a collision type indicator indicating whether the first sidelink reference signal transmission and the second sidelink reference signal transmission have the same scrambling identifier.

Abstract: Disclosed are systems, apparatuses, processes, and computer-readable media for wireless communications. For example, an example of a process for performing sidelink positioning at a user equipment (UE) includes receiving, at the UE, a resource block including a plurality of sidelink symbols in a slot. The slot includes a plurality of slot portions. For instance, a first slot portion of the plurality of slot portions may include at least a first sidelink symbol with at least a first sidelink positioning reference signal (SL-PRS) resource and a second slot portion of the plurality of slot portions may include at least a second sidelink symbol with at least a second SL-PRS resource. The process may further include processing, by the UE, at least one SL-PRS resource in each of the plurality of slot portions of the slot.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) receives positioning assistance data from a location server, the positioning assistance data including at least a first expected measurement value and a first expected measurement uncertainty value defining a first search window during which the UE is expected to measure a first plurality of positioning reference signal (PRS) resources transmitted by a first transmission-reception point (TRP), determines a best symbol hypothesis that is common to a first set of PRS resources of the first plurality of PRS resources, wherein the best symbol hypothesis is a symbol within the first search window during which a signal strength of each PRS resource of the first set of PRS resources is maximized, and measures each PRS resource of a second set of PRS resources of the first plurality of PRS resources only during the best symbol hypothesis.
