Abstract: A user equipment (UE) is described. The UE includes circuitry configured to determine that a physical uplink control channel (PUCCH) with low priority (LP) carrying a LP hybrid automatic repeat request-acknowledgement (HARQ-ACK) overlaps with more than one high priority (HP) PUCCHs carrying HP HARQ-ACKs.
