HARQ Codebook Determination in Wireless Communications

a user equipment (ue) and a network agree on the use of a hybrid automatic repeat request (harq) codebook. the ue receives a plurality of downlink control information (dci) transmissions during a corresponding plurality of physical downlink control channel (pdcch) monitoring occasions from the base station, wherein each dci transmission schedules multiple physical downlink shared channel (pdsch) transmissions on a corresponding one of a plurality of component carriers (ccs), receives a time domain resource allocation (tdra) table configuration from the base station, determines a maximum number of pdsch transmissions per cc based on the tdra table configuration, groups the plurality of ccs together and determines a hybrid automatic repeat request (harq)-acknowledgement (ack) codebook size based on a number of the multiple pdsch transmissions, the maximum number of pdsch transmissions, and a resulting ack or negative acknowledgement (nack) for each of the multiple pdsch transmissions.
