Abstract: A scheduling offset between an uplink and downlink radio frame timing structure of a user equipment (UE) may be updated to provide for more efficient utilization of hybrid automatic repeat request (HARQ) processes in a non-terrestrial network. For instance, different UEs may experience different round trip delays (RTDs) with a non-terrestrial cell. Different UEs may be configured with different scheduling offsets such that scheduling delays may be reduced and HARQ processes identifiers may be reused more rapidly. Additionally or alternatively, wireless communications systems may define one or more separation distances (or timing thresholds) for timing between communications and HARQ processes may be reused based on the separation distance threshold (e.g., such that a satellite may reuse a HARQ process ID for two scheduled communications that have not yet been performed by the UE).

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit information associated with one or more uplink transmissions performed by the UE within an L-band. The UE may receive, after transmitting the information, an adjusted frequency domain resource allocation that indicates an adjusted frequency range to be used by the UE for performing one or more other uplink transmissions. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for signaling a scheduling offset for non-terrestrial networks (NTNs). In one aspect, a method for wireless communications by a user equipment (UE) includes receiving first signaling indicating a first part of a scheduling offset associated with a common timing advance (TA); receiving second signaling indicating a second part of the scheduling offset; and transmitting an uplink transmission based on the first and second parts of the scheduling offset.

Abstract: A method for wireless communication at a network entity and related apparatus are provided. In the method, the network entity receives, from a first user equipment (UE), a communication signal for an end-to-end (E2E) communication with a second UE. The communication signal includes identification data for identifying the second UE for the E2E communication. The network entity further routes the communication signal through the network entity, where the communication signal bypasses ground-based feeder links, and transmits, to the second UE, the communication signal to enable the E2E communication between the first UE and the second UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node, an indication of a subset of tracking reference signal (TRS) resource sets from a plurality of TRS resource sets. The UE may receive, from the network node, a TRS availability indication bitmap that indicates an availability of a TRS associated with the subset of TRS resource sets. The UE may determine that the TRS is available based at least in part on the TRS availability indication bitmap. The UE may receive, from the network node, the TRS based at least in part on the TRS availability indication bitmap indicating that the TRS is available. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) may determine a beam configuration associated with a set of directional beams of a base station. The beam configuration may include a set of identifiers associated with the set of directional beams. The UE may determine beam position information associated with a coverage area of each directional beam of the set of directional beams based on the beam configuration. Additionally or alternatively, the UE may determine beam classification information associated with the coverage area of each directional beam of the set of directional beams based on the beam configuration. The UE may select a directional beam of the set of directional beams based on the beam position information and the beam classification information, and communicate with the base station using the selected directional beam.

Abstract: Aspects relate to techniques for configuring intermittent time domain resources that are usable by a user equipment (UE) for communication with a base station. The base station may transmit a usable time domain resource (TDR) configuration to the UE that indicates the usable time resources that are available to the UE for communication with the base station. The UE may then communicate with the base station based on the usable TDR configuration.
