1. A terminal comprising:
a receiver that receives a synchronization signal block in an unlicensed band of a high frequency band higher than or equal to a frequency band of a frequency range 2 (FR2), the FR2 being in a range including a frequency range 1 (FR1) that is a low frequency band and the FR2 that is a high frequency band in a new radio (NR) system; and
a processor that identifies, based on the received synchronization signal block, an index of a candidate position for a transmission corresponding to the received synchronization signal block, from among candidate positions for transmitting a synchronization signal block, the number of the candidate positions being greater than a predetermined number,
wherein the processor determines that a radio frame in which the synchronization signal block is to be transmitted is only a radio frame with an even system frame number or only a radio frame with an odd system frame number, and identifies a portion of information indicating the index of the candidate position for the transmission based on a value corresponding to the portion of the information indicating the index of the candidate position for the transmission, the value being set in a field assumed to be used for notifying a system frame number of a radio frame in which the synchronization signal block is to be received.
