1. A terminal comprising:
a receiver that receives, by Radio Resource Control (RRC) signaling, configuration information regarding a physical downlink control channel (PDCCH) to configure a common search space; and
a processor that monitors downlink control information in the common search space based on the configuration information,
wherein the configuration information includes information, regarding a search space, that corresponds to bits in an index of a master information block (MIB) and information regarding a search space index associated with a given search space,
monitoring periodicity provided by the configuration information includes a periodicity that is configurable based on the index in the MIB,
the receiver receives information indicative of a synchronization signal block index, the synchronization signal block index being transmitted in a set including one or more synchronization signal blocks,
the downlink control information for a random access response is associated with one synchronization signal block index,
when the common search space is a random access search space for the random access response, the processor monitors the common search space based on monitoring periodicity provided by the configuration information, and
when the common search space comprises at least one of an Other System Information (OSI) search space and a paging search space:
monitoring of the downlink control information in the common search space is associated with a synchronization signal block based on the information indicative of the synchronization signal block index, and
the processor monitors the common search space based on the monitoring periodicity provided by the configuration information and the information indicative of the synchronization signal block index.
