Abstract
Provided are a repetitive transmission method for ultra-low latency and highly-reliable communication in a wireless communication system, and an apparatus therefor. A method for transmitting data by a terminal according to an embodiment of the present invention comprises the steps of: receiving information on the repetition number of transmission for a physical uplink shared channel (PUSCH) from a base station; receiving, from the base station, information on frequency hopping applied to the the PUSCH repetition configuring the the PUSCH repetition; determining a frequency resource for the PUSCH repetition based on the information on the frequency hopping; and performing the the PUSCH repetition.
Claims24
A method of transmitting data by a user equipment in a wireless communication system comprising:
- receiving, from a base station, configuration information adjusting a range of frequency hopping;
- receiving, from the base station, information for number of repetitions of uplink data on the frequency hopping;
