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: 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: 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: 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 transmit a report of a maximum transport block size supported by the UE for if hybrid automatic repeat request (HARQ) feedback is enabled and a maximum transport block size for is HARQ is disabled. The UE may receive, based at least in part on transmitting the report, one or more transport blocks that have a transport block size that does not exceed the maximum transport block sizes supported by the UE. In some aspects, the UE may receive an indication of a length of a span for receiving a set of bits from channel encoder output for a transport block or a redundancy version of a transport block. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a neighbor cell list that indicates at least one neighbor cell. The UE may perform a cell selection procedure or a cell reselection procedure to switch to a serving cell without receiving an updated neighbor cell list from the serving cell. Numerous other aspects are provided.
