Embodiment 1
[0081]
[0082] Image 6 It is a flowchart showing an example of operation of an embodiment of the present invention. In step S1, the base station performs scheduling, and establishes a radio resource allocation plan for downlink and uplink. How to allocate radio resources is indicated by downlink scheduling information for downlink and uplink scheduling information (uplink scheduling grant) for uplink. Downlink and uplink scheduling information is contained in a physical downlink control channel (PDCCH).
[0083]In this embodiment, a mobile communication system using the SC-FDMA scheme for uplink is used. Therefore, when a plurality of resource blocks are allocated to one user, scheduling is restricted so that the plurality of resource blocks occupy a continuous frequency band. When using a multi-carrier scheme such as the OFDM scheme, such restrictions are not required.
[0084] In step S2, a downlink control signal including at least PCFICH and PDCCH and a physical downl
