1. A terminal of a radio communication system for performing communication in a first frequency band and a second frequency band, the second frequency band being higher than the first frequency band, the terminal comprising:
a receiver that receives first configuration information and second configuration information, wherein the first configuration information includes a Quasi co-location, QCL, parameter for a reception of a synchronization signal block in the second frequency band, the QCL parameter being selected from among a first number of candidates for the QCL parameter, the first number being less than a second number of candidates for another QCL parameter to be used in the first frequency band, and wherein the second configuration information allows to configure a second discovery burst transmission window for the reception of the synchronization signal block in the second frequency band such that a maximum value and a minimum value of a length of the second discovery burst transmission window are less than a maximum value and a minimum value of a length of a first discovery burst transmission window in the first frequency band, respectively, and that granularity to set the length of the second discovery burst transmission window is finer than granularity to set the length of the first discovery burst transmission window in the first frequency band; and
a controller that sets the QCL parameter based on the first configuration information and that sets the length of the second discovery burst transmission window based on the second configuration information,
wherein the receiver assumes that a number of the synchronization signal blocks to be received within the second discovery burst transmission window is less than a value of the QCL parameter set by the controller.
