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: Disclosed are techniques for wireless communication. In an aspect, a position estimation entity provides assistance data to sidelink anchors and a UE. The assistance data may include a set of proximity-based sidelink positioning reference signal (PRS) pre-configurations for on-demand PRS position estimation. The target UE transmits a sidelink PRS trigger to trigger an on-demand sidelink PRS position estimation session with a dynamic sidelink anchor group, the sidelink PRS trigger configured to indicate a sidelink zone associated with the UE and a proximity requirement for participation in the on-demand sidelink PRS position estimation. At least one sidelink anchor determines that the proximity requirement to the sidelink zone is satisfied, selects a proximity-based sidelink PRS pre-configuration based on a dynamic proximity to the sidelink zone, and performs a sidelink PRS exchange with the UE.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a communications device (e.g., UE, gNB, LMF, etc.) determines a reference geographic coordinate (e.g., local or global coordinate) for a plurality of sidelink zones, wherein boundaries associated with each sidelink zone are defined via a respective sidelink zone identifier that includes one or more geographic offsets relative to the reference geographic coordinate. A UE receives an indication of the reference geographic coordinate, and performs one or more sidelink zone-related operations based on the reference geographic coordinate.

Abstract: Wireless communications systems and methods related to communicating control information are provided. A method of wireless communication performed by a user equipment (UE) may include mapping a transport block (TB) to a first sub-physical sidelink shared channel (sub-PSSCH) of a plurality of sub-PSSCHs of a PSSCH and transmitting, to at least one other UE, the TB via the first sub-PSSCH.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a repeater receives, from a network entity, a positioning reference signal (PRS) configuration or an indicator of the PRS configuration, the PRS configuration specifying one or more PRS resources of one or more PRS resource sets, and transmits, to one or more user equipments (UEs), a PRS waveform representing the one or more PRS resources of the one or more PRS resource sets in accordance with the PRS configuration.

Abstract: The present disclosure relates to methods and devices for wireless communication at a wireless device of a wireless wearable device. In one aspect, the wireless device may transmit a first report based on one of a location of the wireless wearable device, a time period, or reception of a user-controlled indication to transmit the first report. The wireless device may also receive, based on the transmitted first report, a configuration to switch from a first mode to a second mode. In some aspects, the configuration can include at least one parameter associated with a power savings at the wireless wearable device while in the second mode. Additionally, the wireless device can operate based on the at least one parameter while in the second mode.

Abstract: Mechanisms for rate matching a downlink communication channel in a multi-radio access technology (RAT) communication scenario are described. In one aspect, a method for wireless communication performed by a base station (BS) includes rate matching, based on a rate matching pattern indicating a plurality of reserved resource elements, a downlink (DL) communication channel. The method further includes transmitting, to a user equipment (UE) on one or more antenna ports, a DL communication in the rate matched DL communication channel. The method further includes transmitting, on the one or more antenna ports, one or more signals in the plurality of reserved resource elements. The one or more signals transmitted in the plurality of reserved resource elements may allow UEs associated with other RATs to estimate the rate matched DL communication channel.

Abstract: Aspects described herein relate to sidelink transmissions. In an example, a first user equipment (UE) may receive a multi-opportunity grant from a network entity, the multi- opportunity grant indicating multiple listen-before-talk (LBT) opportunities for scheduling a transmission between the first UE and a second UE; perform a LBT procedure for one or more slots of a plurality of slots indicated by the multiple LBT opportunities; select a first slot of the plurality of slots corresponding to an earliest available LBT based on performing the LBT procedure; and communicate a transmission to the second UE during the transmission time interval (TTI) of the first slot.
