Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for a user equipment (UE) to transmit to a base station a first message of a random access procedure, and the UE may monitor a control channel according to a first monitoring configuration. The UE may receive the second message from the base station in response to the first message. The second message may include a grant for a set of uplink resources for transmitting a third message of the random access procedure. The UE may transmit the third message including a data payload to the base station using the uplink resources, where the third message may include a data payload. The UE may monitor the control channel according to a second monitoring configuration (e.g., monitoring fewer occasions for control information than the first monitoring configuration), and the UE may receive the fourth message.

Abstract: Methods, systems, and devices for wireless communications are described in which a block error rate (BLER) in non-terrestrial network (NTN) communications may be reduced through coverage enhancement techniques. Coverage enhancement techniques may include slot bundling for physical downlink control channel (PDCCH) communications, in which repetitions of a PDCCH may occupy multiple time-frequency locations spanning multiple slots. Such slots can be consecutive or non-consecutive, and in some cases multiple repetitions of the PDCCH may be provided within the same slot. The pattern of the time-frequency locations of repetitions may be periodic or non-periodic. Further, the repetitions can be exact copies, or different redundancy versions of the same encoded DCI. Additionally, repetitions of uplink or downlink shared channel communications, uplink or downlink control channel communication, broadcast channel communications, or any combinations thereof, may be provided.

Abstract: Apparatus, methods, and computer-readable media for facilitating on-demand ephemeris and beam information requests are disclosed herein. An example method for wireless communication at a UE includes transmitting a request for requested information, the requested information including one or more of system information and satellite information. The example method also includes receiving a response message based on the request, the response message including one or more of: an NTN system information block, satellite information associated with at least one requested communication satellite, and beam information associated with the at least one requested communication satellite.

Abstract: Certain aspects of the present disclosure provide techniques for data collection for non-terrestrial networks (NTN). One aspect provides a method for wireless communications by a user equipment (UE). The method generally includes transmitting an indication of a capability of the UE to connect to a network via both terrestrial network (TN) cells and non-terrestrial network (NTN) cells and transmitting one or more data collection reports in accordance with the indicated capability.

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.
