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

Claim 2:
3. A base station which communicates with a user equipment (UE), the base station comprising:
higher layer processing circuitry configured to send first radio resource control (RRC) configuration information and second RRC configuration information, the first RRC configuration information indicating that Physical Downlink Shared Channel Hybrid Automatic Repeat Request-Acknowledgment (PDSCH HARQ-ACK) codebook is semi static, and the second RRC configuration information indicating that PDSCH Aggregation Factor is set to N which is an integer greater than 1;
transmitting circuitry configured to, after a channel access procedure, transmit, to the UE, PDSCHs carrying a transport block in N slots; and
receiving circuitry configured to, for the transport block, receive, from the UE, only a HARQ-ACK information bit, the HARQ-ACK information bit corresponding to a last slot of the N slots;
wherein
a contention window for a channel access procedure is adjusted using a HARQ-ACK information for another slot of the N slots, wherein the HARQ-ACK information is assumed to be the same value as the HARQ-ACK information bit corresponding to the last slot of the N slots.
