1. A method performed by a user equipment, the method comprising:
receiving, from a base station, first downlink control information scheduling a first data transmission in a first set of candidate data transmission occasions, wherein the first downlink control information:
indicates the user equipment to transmit hybrid automatic repeat request acknowledgement feedback for the first set of candidate data transmission occasions; and
includes a first indicator indicating a first set of hybrid automatic repeat request acknowledgement timing values, wherein the first set of hybrid automatic repeat request acknowledgement timing values comprises a set of hybrid automatic repeat request acknowledgement timing values within a plurality of sets of hybrid automatic repeat request acknowledgement timing values, the plurality of sets of hybrid automatic repeat request acknowledgement timing values comprising a set of non-numerical, hybrid automatic repeat request acknowledgement timing values indicating hybrid automatic repeat request acknowledgement feedback transmission is to be suspended, the set of non-numerical, hybrid automatic repeat request acknowledgement timing values corresponding to a numerical indicator;
transmitting, to the base station, a first hybrid automatic repeat request acknowledgement codebook for the first set of candidate data transmission occasions in response to channel access procedure for transmitting the first hybrid automatic repeat request acknowledgement codebook being successful;
receiving, from the base station, second downlink control information scheduling a second data transmission in a second set of candidate data transmission occasions, wherein:
the second downlink control information indicates the user equipment to transmit hybrid automatic repeat request acknowledgement feedback for the second set of candidate data transmission occasions;
the second set of candidate data transmission occasions includes the first set of candidate data transmission occasions;
the second downlink control information includes a second indicator indicating a second set of hybrid automatic repeat request acknowledgement timing values; and
the second set of hybrid automatic repeat request acknowledgement timing values includes the first set of hybrid automatic repeat request acknowledgement timing values; and
transmitting, to the base station, a second hybrid automatic repeat request acknowledgement codebook for the second set of candidate data transmission occasions in response to channel access procedure for transmitting the second hybrid automatic repeat request acknowledgement codebook being successful.
