multiplex, drop, or prioritize the two or more uplink signals for transmission according to the multiplexing rule, dropping rule, or priority rule; and

when the one or more baseband processors are configured to multiplex a first uplink signal carrying a hybrid automatic repeat request acknowledgment (HARQ-ACK) for a downlink data channel dynamically scheduled by a downlink control channel and a second uplink signal carrying a HARQ-ACK for a downlink data channel scheduled in a semi-persistent manner transmitted periodically without being scheduled by a downlink control channel, the one or more baseband processors transmit a base sequence on a dynamic HARQ-ACK PUCCH resource using a cyclic shift corresponding to the values of the dynamic and semi-persistent HARQ-ACKs; and

a memory to store two or more uplink signals.

3. The apparatus of claim 1 , wherein the one or more baseband processors are configured to append X number of bits to one of the two or more uplink signals indicating a scheduling request (SR) state when the two or more uplink signals comprise one or more of i) a physical uplink control channel (PUCCH) format 2, 3, or 4 carrying a hybrid automatic repeat request acknowledgment (HARQ-ACK) and ii) a channel state information (CSI).

4. The apparatus of claim 1 , wherein the one or more baseband processors are configured to:

drop all scheduling requests (SRs) and transmit a hybrid automatic repeat request acknowledgment (HARQ-ACK) on a physical uplink control channel (PUCCH) when the two more overlapping signals comprise i) a PUCCH format 0 or 1 carrying HARQ-ACK and ii) a PUCCH format 1 configured for SR.

5. The apparatus of claim 1 , wherein the one or more baseband processors are configured to:

6. The apparatus of claim 1 , wherein the one or more baseband processors are configured to transmit a physical uplink control channel (PUCCH) signal carrying a combined automatic repeat request acknowledgment (HARQ-ACK), a scheduling request (SR), and a channel state information (CSI) report.

7. The apparatus of claim 1 , wherein the one or more baseband processors are configured to drop one or more of the uplink signals in colliding slots or in all slots, or defer the transmission to the next available slot, when the two or more uplink signals comprise a long physical uplink control channel (PUCCH) signal with multiple slot duration and a long PUCCH or physical uplink shared channel (PUSCH) signal with multiple slot duration.

8. The apparatus of claim 1 , wherein the one or more baseband processors are configured to multiplex uplink control information (UCI) on a physical uplink shared channel (PUSCH) signal on colliding slots or all slots, when the two or more uplink signals comprise a long physical uplink control channel (PUCCH) with multiple slot duration colliding partially with a long PUSCH signal with multiple slot duration.

9. The apparatus of claim 1 , wherein the one or more baseband processors are configured to transmit a long physical uplink control channel (PUCCH) signal carrying a corresponding UCI type in a non-colliding slot wherein the two or more uplink signals comprise the long PUCCH with multiple slot duration carrying a first UCI type colliding partially with a long PUCCH with multiple slot duration carrying a second UCI type.

10. The apparatus of claim 1 , wherein the one or more baseband processors are configured to multiplex the two or more overlapping uplink signals comprising of a physical uplink control channel (PUCCH) signal, a physical uplink shared channel (PUSCH) signal, sounding reference signal (SRS), or a physical random access channel (PRACH) signals, or a combination thereof.

11. The apparatus of claim 1 , wherein the dropping rule may depend on a priority of an uplink control information (UCI) type carried by the two or more uplink signals, on a transmission time of the two or more uplink signals, the traffic type, or the transmission duration of the two or more uplink signals, or a combination thereof.

12. One or more non-transitory machine readable media having instructions thereon that when executed by an apparatus of a user equipment (UE) in a New Radio (NR) system, result in

determining if two or more uplink signals overlap, determine a multiplexing rule, a dropping rule, or a priority rule for the two or more uplink signals based on a type of information included in the two or more uplink signals;

multiplexing, dropping, or prioritizing the two or more uplink signals for transmission according to the multiplexing rule, dropping rule, or priority rule; and

when the UE is configured to multiplex a first uplink signal carrying a hybrid automatic repeat request acknowledgment (HARQ-ACK) for a downlink data channel dynamically scheduled by a downlink control channel and a second uplink signal carrying a HARQ-ACK for a downlink data channel scheduled in a semi-persistent manner transmitted periodically without being scheduled by a downlink control channel, transmitting a base sequence on a dynamic HARQ-ACK PUCCH resource using a cyclic shift corresponding to the values of the dynamic and semi-persistent HARQ-ACKs.

13. The one or more non-transitory machine readable media of claim 12 , wherein the instructions, when executed, further result in

appending 1 bit to one of the two or more uplink signals indicating a presence or absence of a scheduling request (SR) when the two or more uplink signals comprise i) a physical uplink control channel (PUCCH) format 2, 3, or 4 signal carrying a hybrid automatic repeat request acknowledgment (HARQ-ACK) or ii) channel state information (CSI).

14. The one or more non-transitory machine readable media of claim 12 , wherein the instructions, when executed, further result in

appending X number of bits to one of the two or more uplink signals indicating a scheduling request (SR) state when the two or more uplink signals comprise i) a physical uplink control channel (PUCCH) format 2, 3, or 4 carrying a hybrid automatic repeat request acknowledgment (HARQ-ACK) or ii) channel state information (CSI).

15. The one or more non-transitory machine readable media of claim 12 , wherein the instructions, when executed, further result in
