TERMINAL AND TRANSMISSION METHOD

WIPO Patent Application WO/2020/194934

A1

Provided is a terminal that makes it possible to improve the efficiency of random access processing. A control unit (209) in the terminal (200) uses channel quality as a basis to select either a first method for transmitting a random access signal including a preamble section and a data section or a second method for transmitting a random access signal that includes a preamble section and that does not include a data section. A transmission unit (217) transmits a random access signal on the basis of the selected method.
