Hybrid acknowledgement repeat request feedback repetition
In some embodiments, a wireless device transmits, in response to triggering a 2-step random access (RA) procedure, a message A including a preamble and a transport block. The wireless device receives a message B including a RA response that indicates a first number of times to repeat transmission of a hybrid acknowledgement repeat request (HARQ) feedback corresponding to the message B. Then, the wireless device repeats transmission, via an uplink control channel, the HARQ feedback the first number of times.
