Abstract
In a base station, a signal allocating unit allocates downlink control signals (DCI) to a control channel region (CORESET) constituted by a plurality of control channel elements (CCEs), and a transmitting unit transmits the downlink control signals. In this case, the number of resource element groups (REGs) that constitute the CCE is a power of 2, and a bundling size indicating the number of REGs included in the REGs that constitute the CCE and arranged in adjacent resource blocks is a power of 2.
Claims6
An integrated circuit for a base station, the integrated circuit comprising:
- at least one output, which, in operation, outputs a signal, and circuitry, which, in operation, controls:
- setting a control-resource set (CORESET) in a physical downlink control channel (PDCCH) comprising a control channel element (CCE);
- and
- transmitting a downlink control signal in the CORESET,
- wherein the CCE is formed of 6 resource-element groups (REGs) in the CORESET, the 6 REGs being bundled into REG bundles, and
- a REG bundle size of the REG bundles is different according to a number of symbols of the CORESET.
