Abstract: 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. This provides a simple and consistent method to deduce beta offset value for UCI based on priorities of UCI and PUSCH. The solution supports possible multiple different beta offset values determined without extra explicit signaling, i.e., it helps to reduce DCI bits needed to indicate potentially multiple beta offset values.
