    Abstract: Indicating repetitions at a UE in an NTN includes decoding a communication indicating a timing relationship value associated with a distance between a serving satellite and a farthest UE in the NTN. A PRACH communication is encoded for transmission. The PRACH communication includes an indication of a number of PRACH repetitions determined based on the timing relationship value. A RAR including an uplink (UL) grant corresponding to the UE and an indication of a number of RAR repetitions is decoded. The number of RAR repetitions is determined based on the timing relationship value. A PUSCH communication including an indication of a number of PUSCH repetitions is encoded. The number of PUSCH repetitions is determined based on the timing relationship value. A content resolution communication including an indication of a number of content resolution repetitions is decoded. The number of content resolution repetitions is determined based on the timing relationship value.

    Abstract: A user equipment (UE) is configured to establish a network connection including a new radio (NR)-NR dual connectivity band combination wherein a primary cell (PCell) of a primary cell group (PCG) and a primary secondary cell (PSCell) of a secondary cell group (SCG) both operate on frequency range 1 (FR1) and wherein at least one cell of either the PCG or the SCG operates on frequency range 2 (FR2). The UE receives a measurement gap timing advance parameter, selects one subframe from multiple serving cell subframes and determines a starting point for a configured per-frequency range (FR) measurement gap based on the measurement gap timing advance parameter and the selected subframe.

    Abstract: Techniques discussed herein can facilitate beam management for non-terrestrial networks (NTN). One example aspect is A baseband processor, comprising: a memory interface; and processing communicatively coupled to the memory and transceiver interface and, while connected to a base station (BS) within a cell of a non-terrestrial network (NTN) and, where the cell comprises a plurality of bandwidth parts (BWPs) associated with a plurality of beams, configured to perform operations comprising: receiving a signaling from the base station (BS) comprising a channel state indicator reference signal (CSI-RS) configuration associated with a first BWP of the plurality of BWPs, where the CSI-RS configuration comprises a beam measurement configuration for the plurality of beams, switching from a second BWP of the plurality of BWPs to the first BWP according to the CSI-RS configuration and measure one or more of the plurality of beams according to the beam measurement configuration; and generating a measurement report that includes a layer 1 reference signal received power (L1-RSRP) measurement from the measured one or more of the plurality of beams.
