    Abstract: Aspects presented herein may improve the precision and performance of a TDOA-based UE positioning scheme that is associated with an NTN. In one aspect, a UE receives, from a first satellite, a first PRS at a first reception time. The UE receives, from a second satellite, a second PRS at a second reception time and an indication of a transmission-reception time difference, the transmission-reception time difference being a difference between a time the second satellite transmits the second PRS to the UE and a time the second satellite receives an RS from the first satellite. The UE calculates an RSTD for the first PRS and the second PRS based at least in part on the first reception time of the first PRS, the second reception time of the second PRS, and the transmission-reception time difference.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may transmit, and a user equipment (UE) may receive, configuration information related to a random access procedure. For example, in some aspects, the configuration information may include a physical random access channel mask configuration based at least in part on a random access occasion density in a time and frequency domain in a cell served by the base station, a random access response configuration based at least in part on an indication transmitted from the UE to the base station, and/or the like. Accordingly, the UE may perform the random access procedure based at least in part on the configuration information, which may be indicated to the UE in system information, radio resource control signaling, and/or the like. 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 configurations of a set of tracking reference signal (TRS) resource sets. The UE may receive an availability indication associated with one or more TRS resource sets from the set of TRS resource sets, and the availability indication is associated with one or more groups of TRS resource sets associated with the set of TRS resource sets. Numerous other aspects are described.

    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.
