Systems and methods for priority-dependent Uplink Control Information (UCI) resource determination are provided. In some embodiments, a wireless device determines that one or more UCIs are to be multiplexed onto a Physical Uplink Shared Channel (PUSCH); determines priorities of the PUSCH and/or each of the one or more UCIs; determines at least one beta offset value for one or more UCIs based on one or more of the priorities; set or adjust a UCI code rate based on the at least one beta offset value; and transmit a UCI according to the UCI code rate.
