Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a distributed unit (DU) of a network node associated with a non-terrestrial network (NTN), an uplink transmission, wherein the DU is onboard a satellite and a central unit (CU) of the network node is on ground. The UE may receive, from the DU, a downlink transmission based at least in part on a delayed downlink channel monitoring window, wherein the delayed downlink channel monitoring window is based at least in part on a first time offset and a second time offset, the first time offset is associated with a UE-DU round-trip time (RTT), and the second time offset is associated with a CU-DU RTT. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. Techniques described herein provide assisted access to a serving cell for wireless communications. A UE may receive a broadcast system information message from the first cell. The broadcast system information message may include system information usable for communicating with the second cell. Using the received system information, the UE may transmit, to the first cell, a random access channel (RACH) preamble message in order to establish a connection with the second cell. The first cell may transmit, to the second cell in response to receiving the RACH preamble message, a wake-up signal.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine that it is communicating with a particular type of cell (e.g., an air to ground (ATG) cell), and may utilize a timing advance (TA) report format corresponding to the determined cell type. The TA report for an ATG cell may use all 16 bits of a TA report to indicate a TA value according to a small time unit. The TA report for an ATG cell may utilize a subset of bits to indicate a symbol-level TA, and the remainder of bits in the TA report may be unused. The TA report for an ATG cell may be a single octet TA report, including reserved bits and a bit that indicates a format for the TA report, and the TA value. The TA report may include reserved bits and the TA value.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may establish a network interface link with a centralized unit (CU). The network node may establish a set of one or more network interface links with a set of one or more distributed units (DUs). The network node may receive a first communication intended for a destination node via the network interface link. The network node may transmit the first communication to a first DU of the set of one or more DUs via a first network interface link of the set of one or more network interface links. The network node may receive a second communication intended for the destination node via the network interface link. The network node may transmit, after transmitting the first communication via the first network interface link, the second communication to a second DU via a second network interface link. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may establish a first non-cellular connection with a first access point. The UE may transmit, to a first gateway entity via the first access point, a connection setup request for a first cellular connection between the UE and a first network entity. The UE may receive a connection setup message from the first gateway entity via the first access point. The UE may transmit a connection complete message to the first gateway entity via the first access point. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be aboard an aerial vehicle such that the UE is above ground, and in some cases, moving above ground (e.g., flying). The UE may determine to perform an emergency communication procedure (e.g., an emergency call) while the UE meets one or more flying state conditions, where the one or more flying state conditions may be indicative that the UE is in a flying state. The UE may transmit a message to a base station as part of the emergency communication procedure, where the message may be indicative that the UE meets the one or more flying state conditions. The UE may participate in the emergency communication procedure while the UE is in the flying state.

Abstract: Systems and techniques are provided for wireless communications. For instance, a network entity can transmit, to an aerial user equipment (UE), policy information associated with a communication interface of a wireless network. The policy information can include a respective policy corresponding to each aerial zone identifier of a plurality of aerial zone identifiers. The network entity can determine a mapping of a plurality of aerial zones to one or more cells of the wireless network, wherein the mapping is indicative of one or more aerial zone identifiers associated with each respective cell of the one or more cells. The network entity can transmit, based on the mapping, at least one aerial zone identifier associated with a first cell of the one or more cells.

Abstract: Methods, systems, and devices for wireless communications are described. Aerial user equipments (AUEs) may indicate flightpath information to the network (e.g., to a serving network entity). A network entity may request a flightpath report, which may include a sequence of expected geographic locations. An AUE may include estimated timestamps and uncertainty values associated with each timestamp with the flightpath report. Accordingly, the network may manage communications resources for the AUE accounting for the time and associated uncertainty that the AUE will be at each indicated point along the flightpath. A network entity may indicate a filter to apply to the flightpath report, and accordingly the AUE may report the portion of the flightpath that is relevant to the given network entity. The AUE may report the flightpath using an algebraic expression to reduce the amount of data as compared to a flightpath report that includes a set of waypoints.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a radio resource control (RRC) configuration that indicates that hybrid automatic repeat request (HARQ) feedback associated with a downlink HARQ process is disabled or enabled. The UE may receive a downlink control information (DCI) communication that overrides the RRC configuration. The UE may selectively transmit HARQ feedback, associated with the downlink HARQ process, for a downlink transmission based at least in part on the DCI communication. The UE may selectively initiate, based at least in part on selectively transmitting the HARQ feedback, physical downlink control channel (PDCCH) monitoring associated with the downlink HARQ process based at least in part on at least one of the RRC configuration or the DCI communication. Numerous other aspects are described.
