### Claim 3 (depends on 1)

The method according to claim 1,
wherein the first UCI further includes a second HARQ-ACK with the priority index 0, and
wherein encoding of the first UCI includes joint encoding of the CG-UCI and the second HARQ-ACK.

### Claim 4 (depends on 1)

The method according to claim 1, wherein the single physical uplink channel has the priority index 0.
