Classification: CPC H | IPC H

Claim 5:
6. A method for a base station which communicates with a user equipment (UE), the method comprising:
sending first radio resource control (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;
sending second RRC configuration information, the second RRC configuration information indicating that PDSCH Aggregation Factor is set to N which is an integer greater than 1;
after a channel access procedure, transmitting, to the UE, PDSCHs carrying a transport block in N slots; and
for the transport block, receiving, 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.
