US Patent 10135487 Base station, terminal, and communication method

In a base station, a first setting circuitry sets a first Narrowband for allocating a system information block (SIB) for MTC by using a predetermined default offset. A second setting circuitry sets a second Narrowband for allocating a signal other than the SIB by using the default offset and an additional offset that indicates a difference from the default offset. An allocating circuitry allocates the SIB including the additional offset to the first Narrowband, and allocates the signal other than the SIB to the second Narrowband.
