Abstract: Methods, systems, and devices for wireless communications are described Generally, the described techniques provide for a user equipment (UE) to perform a beam switching operation from a current beam to a target beam based on a beam switching duration. The UE may transmit a capability report that may include an antenna pointing capability, a list of one or more detailed capabilities, or both to another device, such as a network entity (e.g., a satellite). The UE may perform the beam switching operation based on the capability report. The UE may perform a random access procedure as part of a change of association operation. The UE may receive a control message from the other device, which may be the network entity, that includes an identity of a target network entity, one or more resources for the random access procedure, an indication of the beam switching duration, or any combination.

Abstract: Aspects described herein relate to receiving, from a network node, a first transmission for configuring a configured grant, wherein the configured grant allocates one or more resources associated with an uplink transmission process having a transmission process identifier, obtaining a first indication that the network node uses a fallback downlink control information (DCI) format, and modifying, based at least in part on obtaining the first indication and the transmission process identifier, the uplink transmission process. Other aspects relate to configuring a device for modifying the uplink transmission process, receiving uplink communications based on the modified uplink transmission process, and/or the like.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus at a UE in NTN are provided. An example method at a UE may include obtaining an indication of a subset of one or more SSB beams included in a set of SSB beams. The example method may further include outputting for transmission or obtaining a communication independent of using any resources associated with SSB transmission via the subset of one or more SSB beams.

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: Certain aspects of the present disclosure provide techniques for indicating actual transport block size (TBS) on shaping encoding. For example, in shaping encoding, instead of using a compensated rate code (e.g., by padding or truncating) for a fixed number of output bits that is often different from the TBS scheduled, the present disclosure supports using multiple actual TBS for a given nominal TBS to improve efficiency of the shaping encoder. A transmitter (e.g., a network entity or use equipment (UE)) may encode a payload size of bits with a shaping encoder to obtain a transport block (TB), which has an actual TBS. The actual TBS is selected from a set of TBSs based on a nominal TBS. The transmitter then transmits to a receiver, an indication of the actual TBS. The indication enables the receiver to decode the corresponding encoded bits. The transmitter then transmits the TB to the receiver.

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.
