Abstract: Apparatus, methods, and computer-readable media for facilitating phase jump estimation for SL DMRS bundling are disclosed herein. An example method includes receiving, from another device, first information at a first symbol of a first slot, the first slot including at least the first symbol and a first reference signal. The example method also includes receiving second information at a second symbol of a second slot, the second slot including at least the second symbol and a second reference signal, the first information and the second information being repetitions. The example method also includes generating a first reference signal copy based at least on the second reference signal and a phase jump between the first slot and the second slot. Additionally, the example method includes performing channel estimation across the first slot and the second slot based on an aggregation of the first reference signal and the first reference signal copy.

Abstract: In an aspect, a user equipment (UE) may receive positioning assistance data from a location server, wherein the positioning assistance data identifies one or more first positioning reference signal (PRS) resources for measurement by the UE during a positioning session between the UE and a location server. The UE may receive post-measurement positioning assistance data from at least one sidelink device located within a threshold distance to the UE, wherein the post-measurement positioning assistance data received from the at least one sidelink device is based on measurements of one or more second PRS resources obtained by the at least one sidelink device during a positioning session of the at least one sidelink device. The UE may selectively measure at least a subset of the one or more first PRS resources based on the post-measurement positioning assistance data received from the at least one sidelink device.

Abstract: Methods, systems, and devices for wireless communications are described for improving sidelink communication reliability. In some examples, a user equipment (UE) may map allocated sidelink resources from a logical domain to a physical domain, where the mapped resources may include greater frequency diversity in the physical domain A frequency range of a sidelink control channel or of a sidelink data channel may be greater in the physical domain than in the logical domain after the mapping. In some examples, sidelink communications may be associated with an aggregation factor that represents a number of repetitions of a sidelink communication. In this example, a UE may repeat a sidelink communication within a contention-based resource pool a number of times before receiving feedback in order to increase communication reliability. A first UE may communicate a sidelink communication with a second UE using a resource mapping or repetitions of the sidelink communication.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a controller user equipment (UE) may transmit, to a network node, a relay scheduling request that indicates a request to schedule access to a universal mobile telecommunications system air interface (Uu) based at least in part on relaying one or more sidelink retransmissions associated with at least a first sidelink between the controller UE and a first sidelink UE. The UE may communicate the one or more sidelink retransmissions between the controller UE and the network node based at least in part on using the Uu. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an uplink grant that schedules a communication in a scheduled resource and that includes first transmission parameters associated with the scheduled resource. The UE may select, in response to the uplink grant being a soft uplink grant, second transmission parameters that include new transmission parameters not included in the first transmission parameters or include modified first transmission parameters. The UE may transmit the communication in the scheduled resource or a subset of the scheduled resource using at least the second transmission parameters. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first device may receive, from a second device, a sounding reference signal (SRS) prior to a scheduled communication. The first device may transmit, to the second device, an indication that a measurement of the SRS does not satisfy a threshold, if the measurement of the SRS does not satisfy the threshold. The first device may activate, based at least in part on the transmitting the indication and before the scheduled communication, a multi-point communication mode. Numerous other aspects are described.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a position estimation entity (e.g., UE, gNB, LMF, etc.) identifies a pool of UEs for a SL-assisted position estimation procedure of a set of target UEs. SL SRS-Ps are communicated (e.g., transmitted and measured) between the pool of UEs (e.g., for relative SL ranging). UL SRS-Ps are communicated by at least some of the UEs in the pool of UEs. The position estimation entity obtains measurement data for both the SL SRS-P and UL-SRS-P communications. The position estimation entity determines a position estimate for each UE in the set of UEs based on the measurement information.
