Method for transmitting/receiving PUSCH in wireless communication system, and device therefor
The present specification presents a method for transmit-ting a PUCCH in a wireless communication system. A method performed by means of a terminal comprises the steps of: receiving, from a base station, configuration information about a time domain window; receiv-ing, from the base station, downlink control information (DCI) including scheduling information for a PUSCH and frequency hopping informa-tion for the PUSCH; transmitting the PUSCH to the base station at a first frequency hop having the same length as a first time domain window; and transmitting the PUSCH to the base station at a second frequency hop having the same length as a second time domain window.

receiving, by the UE from the BS, downlink control information (DCI) for scheduling of the PUSCH;
transmitting, by the UE to the BS, the PUSCH based on i) the DMRS bundling enable information and ii) the frequency hopping configuration,
