Data transmission method for ultra-low latency and highly-reliable communication in wireless communication system, and apparatus therefor

A user equipment transmitting data in a wireless communication system, the user equipment comprising:

• a Radio Frequency (RF) unit configured to receive, from a base station, downlink control information including a number of repetitions to be applied in a physical uplink shared channel (PUSCH) transmission on frequency hopping;
• and
• a processor configured to determine PUSCH repetitions corresponding to the number of repetitions and perform the frequency hopping according to the determined PUSCH repetitions,
• wherein the performing the frequency hopping includes:
• a first PUSCH repetition, using a plurality of resource blocks (RBs) including a first basic resource block (RB), and a second PUSCH repetition, using a plurality of RBs including a second basic RB which is apart from the first basic RB with an offset, and
• wherein the offset between the first basic RB and the second basic RB is determined based on a size of bandwidth part (BWP) which is activated for an uplink data transmission.

A method of receiving data by a base station in a wireless communication system comprising:

• transmitting, to a user equipment, downlink control information including a number of repetitions to be applied in a physical uplink shared channel (PUSCH) transmission on frequency hopping;
• and
• determining PUSCH repetitions corresponding to the number of repetitions,
• receiving, from the user equipment, a first PUSCH repetition, using a plurality of resource blocks (RBs) including a first basic resource block (RB), and a second PUSCH repetition, using a plurality of RBs including a second basic RB which is apart from the first basic RB with an offset, and
• wherein the offset between the first basic RB and the second basic RB is determined based on a size of bandwidth part (BWP) which is activated for an uplink data transmission.
