The PUCCH-BFR and the at least one other signal may be multiplexed in a CC or in multiple CCs.

The UE may multiplex the PUCCH-BFR with the at least one other signal according to the rules.

The gNB may also encode the DMRS symbols for transmission in accordance with the gap and may encode the associated PDSCH for transmission during the gap between the DMRS symbol transmissions at symbol times following the DMRS symbols.
