Claim 6:
7. A system comprising a base station and a terminal, wherein the base station comprises:
a transmitter that transmits a configuration for a synchronization signal/physical broadcast channel (SS/PBCH) block transmission candidate position in a transmission duration in which one or more SS/PBCH blocks are transmitted in an unlicensed spectrum, wherein the SS/PBCH block transmission candidate position corresponds to an SS/PBCH block index; and
a processor that controls, by using the configuration, so that a physical downlink shared channel is not mapped to a resource corresponding to the SS/PBCH block transmission candidate position regardless of whether or not the one or more SS/PBCH blocks are transmitted in the resource, and
the terminal comprises:
a receiver that receives the configuration; and
a processor that controls, based on the configuration, reception of the physical downlink shared channel, assuming that the physical downlink shared channel is not mapped to the resource regardless of whether or not the one or more SS/PBCH blocks are transmitted in the resource,
wherein a number of SS/PBCH blocks with a given SS/PBCH block index transmitted in the transmission duration is not larger than one.
