Technical Field The present disclosure relates to a terminal and a transmission method. Background A communication system called "fifth generation mobile communication system (5G)" has been studied. In 5G, it has been studied to flexibly provide functions for each use case requiring high reliability and low delay, in which high-speed communication services are required to be increased, and the number of terminals to be connected is increased. The third generation partnership project (3rd Generation Partnership Project,3GPP), which is an international standard organization, has studied the elevation of communication systems from both the elevation of the long term evolution (Long Term Evolution, LTE) system and the elevation of New Radio (NR). The 3GPP has studied the support of the wireless communication technology (vehicle to everything, V2X) for vehicles in the LTE system. In NR that can use a wider band than the LTE system, V2X support is also being studied (for example, see non-patent document 1).
