Claim 13:
14. A method at a remote unit comprising:
receiving, from a base unit, one or multiple downlink transmissions within a channel occupancy time initiated by the base unit, a first message indicating a first candidate opportunity for transmission of a hybrid automatic repeat request-acknowledgement codebook corresponding to the one or multiple downlink transmissions and a second message indicating a number of allowed opportunities for transmission of the hybrid automatic repeat request-acknowledgement codebook;
determining the hybrid automatic repeat request-acknowledgement codebook and a number of total candidate opportunities for transmission of the hybrid automatic repeat request-acknowledgement codebook; and
in response to a channel access for the first candidate opportunity being successful, transmitting the hybrid automatic repeat request-acknowledgement codebook in the first candidate opportunity, and, in response to the channel access for the first candidate opportunity being failed and the number of the total candidate opportunities being larger than one, attempting to transmit the hybrid automatic repeat request-acknowledgement codebook in a second candidate opportunity.
