FIELD: communication.
SUBSTANCE: terminal apparatus receives a signal on the carrier frequency of an unlicensed band based on M potential positions in time in order to receive an SS block. Detection is performed consecutively for the SS block at each potential position in time from the M potential positions in time on the carrier frequency of the unlicensed band until the SS block is received at N potential positions in time or until detection is performed for the SS block at the last potential position in time from the M potential positions in time, wherein N constitutes the amount of potential positions in time wherein the network apparatus is expected to send the SS block, and N constitutes a positive integer less than or equal to M.
EFFECT: transmission of synchronous signal blocks in an unlicensed frequency band.
