Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, from a network entity, a cross-link interference (CLI) sounding reference signal (SRS) measurement resource configuration that indicates an orthogonal time frequency space (OTFS) modulated SRS associated with a second UE. The first UE may receive, from the second UE, the OTFS modulated SRS based at least in part on the CLI SRS measurement resource configuration. The first UE may perform a CLI measurement over one or more symbols in which the OTFS modulated SRS is transmitted. The first CE may transmit, to the network entity, a measurement report that indicates the CLI measurement. Numerous other aspects are described.

Abstract: Method and apparatus for an initial E2E discovery procedure in direct NTN networks. The apparatus receives, from a network entity, an indication indicating support for a direct NTN communication. The direct NTN communication between the first UE and at least a second UE bypasses ground-based feeder links. The apparatus transmits, to the network entity, a communication request for the direct NTN communication with at least the second UE based on the indication indicating support for the direct NTN communication. The communication request is transmitted to the second UE via the direct NTN communication. The apparatus receives, from the second UE, a communication request feedback message indicating that the second UE is reachable over the direct NTN communication. The communication request feedback message is received from the second UE via the direct NTN communication.

Abstract: Disclosed are systems, apparatuses, processes, and computer-readable media for wireless communications. For example, an example of a process may include a RIS that can receive, from a satellite, a positioning reference signal. The RIS can further reflect the positioning reference signal to produce a reflection positioning reference signal radiated towards a network device for positioning of the network device.

Abstract: Apparatus, methods, and computer-readable media for facilitating SSBs for reduced capability UEs in an NTN are disclosed herein. An example method for wireless communication at a UE includes monitoring in a first resource for at least a part of a first portion of a first SSB of a non-terrestrial network and a second portion of the first SSB, the first resource being associated with a first beam. The example method also includes monitoring for a second SSB of the non-terrestrial network on a second beam in a second resource that overlaps at least in part with the second portion of the first SSB.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may communicate in a network based at least in part on using a first connection configuration. The UE may communicate in the network based at least in part using a second connection configuration instead of the first connection configuration. The UE may autonomously switch to reusing the first connection configuration for communicating in the network based at least in part on the first connection configuration being stored at the UE. Numerous other aspects are described.

Abstract: A method of assessing a reported UE location includes: receiving, at a network entity, the reported UE location; obtaining, at the network entity, a first signal frequency difference indicating a first difference between a received frequency of a first signal received by the UE corresponding to a first transmit signal of a first transmit frequency transmitted from a first non-terrestrial-network node, and a received frequency of a second signal received by the UE corresponding to a second transmit signal of a second transmit frequency transmitted from a second non-terrestrial-network node that is separate from the first non-terrestrial-network node; and providing, by the network entity, a UE location assessment indication based on the first signal frequency difference and a second difference between an expected frequency of the first signal at the reported UE location and an expected frequency of the second signal at the reported UE location.

Abstract: Systems and techniques are provided for wireless communications. For example, an apparatus (e.g., a user equipment (UE)) may receive a downlink transmission in a first downlink time slot and receiving an update to a scheduling offset associated with a propagation time delay of communications between the apparatus and a network entity. The update indicates an updated scheduling offset. The apparatus may determine a selected scheduling offset as one of the scheduling offset or the updated scheduling offset. The apparatus may transmit, using a second uplink time slot, an uplink transmission associated with the downlink transmission. The second uplink time slot may be determined based on a first uplink time slot and the selected scheduling offset.

Abstract: A user equipment (UE) transmits a first message spanning a set of physical resource blocks (PRBs). The UE retransmits a first portion of the first message associated with a first subset of one or more PRBs in the set of PRBs, the set of PRBs grouped into a set of PRB bundles including a first subset of PRB bundles corresponding to the first subset of the one or more PRBs and skips retransmission of a second portion of the first message associated with a second subset of the PRB bundles of the set of PRB bundles, the second subset of the PRB bundles corresponding to at least a portion of remaining PRBs in the set of PRBs.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a network node, downlink control information (DCI) that schedules a downlink transmission and one or more repetitions of the downlink transmission. The DCI may indicate a first uplink resource for a first feedback message indicating whether the UE receives the downlink transmission and the one or more repetitions. Based on receiving the DCI, the UE may select a second uplink resource for a second feedback message indicating feedback that the UE received the DCI, where the second uplink resource occurs prior to the first uplink resource in a time domain. The UE may transmit the second feedback message on the second uplink resource. The UE and the network node may be part of a non-terrestrial network and, in some examples, may apply a configuration indicated in the DCI based on the second feedback message.
