1. A method of wireless communication comprising:
receiving, by a wireless device from a network node, a first downlink control information (DCI) format comprising a first downlink assignment indicator (DAI) corresponding to one or more first physical downlink control channels (PDCCHs) in a unicast service;
receiving, by the wireless device from the network node, a second DCI format comprising a second DAI corresponding to one or more second PDCCHs in a multicast service,
wherein each of the first DAI for the unicast service and the second DAI for the multicast service indicates an accumulated number of PDCCHs that schedules one or more physical downlink shared channels (PDSCHs) up to a current PDCCH first in an ascending order of PDSCH reception starting time for a same serving cell and PDCCH monitoring occasion, second in an ascending order of serving cell index, then in an ascending order of PDCCH monitoring occasion index; and
determining, based on the first DAI and the second DAI, a hybrid automatic repeat request (HARQ) codebook for the unicast service and the multicast service, wherein the HARQ codebook is determined by:
determining a first HARQ sub-codebook for the unicast service and a second HARQ sub-codebook for the multicast service, and
concatenating the first HARQ sub-codebook and the second HARQ sub-codebook.
