    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: Systems and methods provide for physical downlink control channel (PDCCH) monitoring adaptation. A user equipment (UE) may monitor a default search space set group (SSSG) for downlink control information (DCI) from a base station in the PDCCH. In response to a first DCI trigger, the UE switches from monitoring the default SSSG to monitoring a first non-default SSSG associated with a first timer. In response to a second DCI trigger, the UE switches from monitoring the first non-default SSSG to monitoring a second non-default SSSG associated with a second timer. The first non-default SSSG may be a non-empty SSSG including a search space set with at least one associated search space. The second non-default SSSG may be an empty SSSG with no associated search space to emulate PDCCH skipping.
