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.
