Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a coordinate switch indication that indicates that the UE is to calculate a first value of a new ephemeris coordinate of a plurality of coordinates. The UE may calculate the first value of the new ephemeris coordinate based on one or more other ephemeris coordinates of the plurality of ephemeris coordinates and may generate ephemeris information, associated with a non-terrestrial communication device, based on the calculation of the first value of the new ephemeris coordinate. The UE may communicate with the non-terrestrial communication device based on the ephemeris information. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for resuming communications with a non-terrestrial network in discontinuous coverage. A method that may be performed by a user equipment (UE) includes determining that the UE is or will be in an out-of-coverage state with a non-terrestrial network (NTN) for a first duration; entering a power saving state in response to the determination; exiting the power saving state when the UE expects to be in an in-coverage state with the NTN; and taking one or more actions to resume communications with the NTN.

Abstract: Various aspects described herein relate to dynamically controlling a time when random access initiated in a target cell of a non-terrestrial network. For example, when a user equipment (UE) detects an event that triggers a random access procedure in the target cell, the UE may monitor a control channel from the target cell for a control signal during a target cell monitoring window prior to initiating random access in the target cell. For example, the control signal may include a dynamic indication to identify UEs allowed to initiate random access, whereby a UE is not permitted to autonomously start contention-based random access in the target cell during the target cell monitoring window unless the UE has received the control signal. In this way, the target cell may regulate a rate at which UEs initiate the RACH procedure in order to manage congestion in the target cell.

Abstract: A method for obtaining flight path information comprises: receiving, at a network entity, a capability report indicating a capability of a UE to report a flight path of the UE; and transmitting, from the network entity, a flight path report message that requests the UE to provide: partial-path reporting by reporting first flight path information indicative of a portion of the flight path of the UE that is less than all of the flight path; or triggered reporting by reporting second flight path information in response to occurrence of a trigger event, the second flight path information indicative of at least some of the flight path of the UE; or differential reporting by reporting third flight path information indicative of a difference between a present flight path of the UE and a previous flight path of the UE; or any combination thereof.

Abstract: A user equipment (UE) operating as an NR-Light UE may repeat transmissions of uplink signals such as a random access (RA) message (Msg) 3 on a physical uplink shared channel (PUSCH) during a random access channel (RACH) procedure. The UE may receive a random access response (RAR) message including a RAR uplink (UL) grant. The UE may determine, based on a single bit of the RAR message, whether repetition of a RA Msg 3 is indicated. The UE may determine both of a repetition factor and a transmit power control (TPC) command for the RA Msg 3 based on a TPC field of the RAR UL grant. The UE may transmit the RA Msg 3 based on the repetition factor and the TPC command.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a non-terrestrial network (NTN) entity, a message that is associated with an uplink grant. The UE may select, based at least in part on the message, either a cell-specific offset or an updated offset that is indicated after initial access, as a timing offset that accounts for a propagation delay between a base station of the NTN and the UE. The UE may transmit, to the NTN entity, an uplink communication using the timing offset. 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 one or more repetitions of a broadcast message for broadcast service in one or more transmission occasions. The UE may determine a hybrid automatic repeat request (HARQ) configuration that indicates whether HARQ combining is supported for the broadcast message based at least in part on one or more properties of the broadcast message. The UE may perform a decode attempt on a transport block carried in the one or more repetitions of the broadcast message based at least in part on the HARQ configuration. 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, from a base station, a multicast message or a broadcast message that uses a radio link control (RLC) format associated with an RLC acknowledged mode (RLC-AM). The UE may decode the multicast message or the broadcast message to identify information associated with an RLC unacknowledged mode (RLC-UM) based at least in part on a capability of the UE. The UE may operate in accordance with the RLC-UM based at least in part on decoding the multicast message or the broadcast message. Numerous other aspects are provided.

Abstract: A UE may receive, from at least one cell via at least one bit in a MIB or a SIB, a barring indication based on a supported network of the at least one cell and a supported network of the UE. The supported network of the at least one cell may correspond to a TN or an NTN, and the supported network of the UE may correspond to a TN or an NTN. The UE may skip, based on the received barring indication, a selection of the at least one cell for communication. Accordingly, the UE may not camp on the at least one cell. The barring indication for NTN-supporting UEs and for TN-supporting UEs may be separately indicated via the MIB or the SIB.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network entity, a logged measurement configuration that defines an event for event triggered measurement logging, wherein the event is associated with a radio access technology (RAT)-specific coverage hole or a frequency specific coverage hole. The UE may perform, based at least in part on the logged measurement configuration, measurement logging based at least in part on an occurrence of the event associated with the RAT-specific coverage hole or the frequency specific coverage hole. Numerous other aspects are described.
