Abstract
In a base station, a setting unit for setting the number of detections sets at least one search space that includes plural control channel candidates to be targets of detection of a control signal in a terminal, and a transmission unit transmits the control signal that is mapped on any of the plural control channel candidates in the search space. Here, the number of detections in the search space by the terminal is determined based on settings of the terminal.
Claims11
A terminal comprising:
- a receiver, which, in operation, receives a signal;
- and
- circuitry, which, in operation, monitors a plurality of control channel candidates in a plurality of physical downlink control channel (PDCCH) search space sets in the signal,
- wherein:
- a maximum number of the monitored control channel candidates in a slot depends on a subcarrier interval,
- a relation between the maximum number of the monitored control channel candidates in the slot and the subcarrier interval is different from an inversely proportional relation,
- a first subcarrier interval is one-quarter a second subcarrier interval, and
- a first maximum number of the monitored control channel candidates in the slot with the first subcarrier interval is less than four times a second maximum number of the monitored control channel candidates in the slot with the second subcarrier interval.
