Abstract: Methods and apparatuses for transmission of k repetitions over a channel are described. Repetition formats for the transmissions include options for slot-based repetition, mini-slot based repetition, intra-slot frequency hopping, inter-slot frequency hopping, data splitting, data switching, and DMRS sharing, among others. In some examples, intra-slot frequency hopping is performed. A first repetition of the k repetitions is sent over the channel, starting from a first symbol within a first slot, and using a first set of frequency resources. A second repetition of the k repetitions is sent over the channel, following the first repetition and starting from a second symbol within the first slot, and using a second set of frequency resources.
