Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may perform a mobility operation in or to a non-terrestrial network (NTN). The UE may transmit a report indicating a success or failure of the mobility operation, wherein the report is associated with a timing difference of the mobility operation satisfying a threshold associated with at least one of the NTN or the mobility operation. 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 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. 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: 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.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may obtain a first value associated with transmitting an uplink communication that corresponds to a downlink communication received in a non-terrestrial network (NTN). The UE may compare the first value to a second value. The UE may selectively transmit the uplink communication, or selectively process the downlink communication, based at least in part on a result of comparing the first value to the second value. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may transmit, and a user equipment (UE) may receive, signaling that indicates at least a first random access channel (RACH) occasion (RO) partition and a second RO partition. The first RO partition may be associated with different uplink transmission capabilities than the second RO partition. The UE may select an RO in the first RO partition or the second RO partition based at least in part on a metric that relates to an uplink transmission capability of the UE. The UE may transmit, and the network node may receive, a preamble in the selected RO to initiate a RACH procedure. Numerous other aspects are described.
