Patent ID: 11917615
Assignee: SHARP KABUSHIKI KAISHA
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 1:
2. A base station device comprising:
transmission circuitry configured to transmit a physical downlink control channel (PDCCH) with a downlink control information (DCI) format used for scheduling a physical downlink shared channel (PDSCH) for a serving cell, a frequency domain resource assignment field in the DCI format being used for indicating frequency domain resources for the PDSCH, and at least based on that all bits in the frequency domain resource assignment field are set to 1, and
reception circuitry configured to receive a one-shot hybrid auto repeat request-acknowledgment (HARQ-ACK) information comprising of a HARQ-ACK information bit for each of HARQ processes configured for the serving cell, wherein
in a case that the all bits in the frequency domain resource assignment field are set to 1, the PDSCH is not scheduled by the DCI format.
