Abstract: A method for repeating a Transport Block (TB) over multiple transmission occasions. The method includes exchanging specific signaling between a wireless device (e.g., a user equipment) and a network node (e.g., a base station) to repeat same or different redundancy versions of the TB in multiple non-overlapping transmission occasions (e.g., mini-slots) corresponding to multiple Transmission Configuration Indication (TCI) states and having different start positions. More specifically, the network node transmits a Time Domain Resource Allocation (TDRA) to indicate the multiple non-overlapping transmission occasions and the wireless device receives the TDRA indicating the multiple non-overlapping transmission occasions. Accordingly, the wireless device can receive repetition of the TB according to the TDRA.

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.
