Abstract: Disclosed are various techniques for wireless communication. In some aspects, a method of wireless communication performed by a user equipment (UE) includes determining a positioning reference signal (PRS) to random access channel (RACH) occasion (RO) mapping that defines specific ROs during which the UE should at least transmit a RACH sequence based on specific PRS measurements. The method also includes performing at least one PRS measurement. The method also includes transmitting a RACH sequence on at least one RO according to the PRS to RO mapping and based on the specific PRS measurement. The method optionally includes reporting a result of the PRS measurement to the base station according to the PRS to RO mapping based on the PRS measurements.

Abstract: Apparatus, methods, and computer-readable media for facilitating reusing an air-to-ground communication system to support message-relaying for UEs in remote areas are disclosed herein. An example method for wireless communication at a user equipment (UE) includes establishing an access link with a terrestrial network. The example method also includes establishing a message layer of the access link for communicating with a payload deployed on-board an aerial device. The example method also includes communicating a communication with the aerial device using the message layer, the communication including a message to be provided to the terrestrial network or received from the terrestrial network.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a measurement resource. The UE may perform a Layer 3 (L3) measurement of the measurement resource using a first polarization that is dedicated for performing L3 measurements and that is supported by the UE. Numerous other aspects are described.

Abstract: Aspects presented herein may improve the precision and performance of a TDOA-based UE positioning scheme that is associated with an NTN. In one aspect, a UE receives, from a first satellite, a first PRS at a first reception time. The UE receives, from a second satellite, a second PRS at a second reception time and an indication of a transmission-reception time difference, the transmission-reception time difference being a difference between a time the second satellite transmits the second PRS to the UE and a time the second satellite receives an RS from the first satellite. The UE calculates an RSTD for the first PRS and the second PRS based at least in part on the first reception time of the first PRS, the second reception time of the second PRS, and the transmission-reception time difference.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for PDSCH rate-matching in NTN systems. A UE may receive an indication of a subset of one or more SSB beams included in a set of SSB beams having one or more PDCCH resources reserved for potentially scheduling one or more SIBs associated with the set of SSB beams. The UE may further receive a PDSCH associated with resources that overlap with at least a portion of the one or more PDCCH resources associated with the indication of the subset of one or more SSB beams, and rate-match around the one or more PDCCH resources associated with the indication of the subset of one or more SSB beams for receiving the PDSCH.

Abstract: A UE transmits a sidelink synchronization signal in response to a communication trigger, the sidelink synchronization signal including an indication of the communication trigger to be provided to a network. The UE receives a sidelink message from an aerial device in response to the sidelink synchronization signal. An aerial device receives, from a UE, a sidelink synchronization signal including an indication of a communication trigger associated with communication for a network. The aerial device transmits a sidelink message to the UE in response to reception of the sidelink synchronization signal that includes the indication of the communication trigger.

Abstract: A UE includes a processor configured to: receive, in a primary cell, a dormant indication of a dormant state of a secondary cell; and respond to receiving the dormant indication by implementing the dormant state of the secondary cell by inhibiting monitoring of a physical downlink control channel of the secondary cell; where the processor is configured to respond to a positioning signal including a first portion that is configured within a bandwidth of the secondary cell and that is received while the secondary cell is in the dormant state by: withholding processing of the positioning signal; or withholding processing of the first portion of the positioning signal and processing a second portion, if any, of the positioning signal that is configured outside the bandwidth of the secondary cell; or processing the positioning signal.

Abstract: A user equipment (UE) operating in a discontinuous reception (DRX) mode may receive a wake-up signal indicating that the UE may skip the next ON duration of the DRX cycle, i.e., the UE is instructed to not wake up during a next ON time during the DRX cycle to monitor communication signals, such as data signals or control signals. The UE may be configured to receive downlink (DL) positioning reference signals (PRSs), e.g., during the next ON duration of the DRX cycle. The UE respond to the PRS configuration and the wake-up signal by remaining in DRX sleep mode and not receiving the PRS or transitioning to DRX ON mode to receive the PRS during which the UE may monitor or not monitor communication signals. The location server may receive indications of the wake-up signal configuration and status from a base station or the UE.
