circuitry configured to

decode the master information block;

determine whether the information element included in the master information block indicates that the second system information block is being transmitted from the base station;

ignore the first system information block and control the receiver to receive the second system information block when it is determined that the information element indicates that the second system information block is being transmitted from the base station; and

decode the second system information block including second scheduling information indicating a time domain window for receiving at least one additional block of system information for the reduced-capability terminals, wherein

the information element is a one bit flag indicating whether the second system information block is being transmitted from the base station, and

the first system information block is transmitted at a fixed scheduled having a periodicity of 80 ms.

2. The wireless terminal device of claim 1, wherein

the master information block includes timing information relating to a transmission timing of the first system information block.

3. The wireless terminal device of claim 1, wherein
