Title:
TERMINAL AND COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2021/172338
Kind Code:
A1
Abstract:
This terminal is provided with: a reception unit for receiving, from a base station, a parameter relating to a random access procedure; a control unit that determines a time domain position of a physical uplink shared channel (PUSCH) slot on the basis of a time domain position of a physical random access channel (RACH) slot, a sub-carrier interval of the RACH slot, a sub-carrier interval of the PUSCH slot, and the parameter; and a transmission unit that transmits the PUSCH at the determined time domain position to the base station.
