## Abstract

The present application relates to wireless devices, and more particularly to apparatus, systems, and methods for multiplexing Configured Grant (CG) transmissions in New Radio (NR) systems operating on unlicensed spectrum. In one embodiment, a method for signaling a wireless system is disclosed, comprising: determining, by a user equipment (UE), that a physical uplink control channel (PUCCH) overlaps with a configured grant (CG) physical uplink shared channel (PUSCH) within a PUCCH group; multiplexing uplink control information (UCI) with a CG UCI based on the determination; and transmitting, by the UE to the wireless system, the multiplexed UCI with the CG UCI.

## Claims

### Claim 1

A method for signaling a wireless system, comprising:
determining, by a user equipment (UE), that a physical uplink control channel (PUCCH) overlaps with a configured grant (CG) physical uplink shared channel (PUSCH) within a PUCCH group;
multiplexing uplink control information (UCI) with a CG-UCI based on the determination, wherein the CG-UCI contains an indication whether a hybrid automatic repeat request acknowledgment (HARQ-ACK) or channel state information (CSI) is multiplexed; and
transmitting, by the UE to the wireless system, the multiplexed UCI with the CG-UCI.

### Claim 2 (depends on 1)

The method of claim 1, wherein the multiplexing comprises multiplexing the UCI with the CG-UCI on a CG physical uplink shared channel (PUSCH).

### Claim 3 (depends on 1)

The method of claim 1, further comprising scheduling the CG-UCI for transmission after one or more demodulation reference signals (DMRSs) symbol, and wherein transmitting the multiplexed UCI with the CG-UCI is based on the scheduling.

### Claim 4 (depends on 3)

The method of claim 3, further comprising scheduling for transmission after the CG-UCI, one or more of: a hybrid automatic repeat request acknowledgement (HARQ-ACK), channel state information (CSI) part 1, CSI part 2, and data.

### Claim 5 (depends on 3)

The method of claim 3, further comprising scheduling a hybrid automatic repeat request acknowledgement (HARQ-ACK) for transmission before the CG-UCI.

### Claim 6 (depends on 1)

The method of claim 1, wherein the CG-UCI is jointly encoded with a hybrid automatic repeat request acknowledgment (HARQ-ACK) feedback.

### Claim 7 (depends on 1)

The method of claim 1, wherein the CG-UCI a hybrid automatic repeat request acknowledgment (HARQ-ACK) feedback are encoded based on the HARQ-ACK feedback.

### Claim 8 (depends on 1)

The method of claim 1, wherein the CG-UCI or a legacy UCI is dropped based on a predefined priority order for UCIs.

### Claim 9

A wireless device comprising:
an antenna;
a radio operably coupled to the antenna; and
a processor operably coupled to the radio; and
wherein the wireless device is configured to:
determine that a physical uplink control channel (PUCCH) overlaps with a configured grant (CG) physical uplink shared channel (PUSCH) within a PUCCH group;
multiplex uplink control information (UCI) with a CG-UCI based on the determination, wherein the CG-UCI contains an indication whether a hybrid automatic repeat request acknowledgment HARQ-ACK or channel state information CSI is multiplexed; and
transmit, to a wireless system, the multiplexed UCI with the CG-UCI.

### Claim 10 (depends on 9)

The wireless device of claim 9, wherein the multiplexing comprises multiplexing the UCI with the CG-UCI on a CG physical uplink shared channel (PUSCH).

### Claim 11 (depends on 9)

The wireless device of claim 9, wherein the wireless device is further configured to schedule the CG-UCI for transmission after one or more demodulation reference signals (DMRSs) symbol, and wherein transmitting the multiplexed UCI with the CG-UCI is based on the schedule.

### Claim 12 (depends on 11)

The wireless device of claim 11, wherein the wireless device is further configured to schedule for transmission after the CG-UCI, one or more of: a hybrid automatic repeat request acknowledgement (HARQ-ACK), channel state information (CSI) part 1, CSI part 2, and data.

### Claim 13 (depends on 11)

The wireless device of claim 11, wherein the wireless device is further configured to schedule a hybrid automatic repeat request acknowledgement (HARQ-ACK) for transmission before the CG-UCI.

### Claim 14 (depends on 9)

The wireless device of claim 9, wherein the CG-UCI is jointly encoded with a hybrid automatic repeat request acknowledgment (HARQ-ACK) feedback.

### Claim 15

A non-transitory computer-readable medium that stores instructions that, when executed, cause one or more processor of a device to:
determine that a physical uplink control channel (PUCCH) overlaps with a configured grant (CG) physical uplink shared channel (PUSCH) within a PUCCH group;
multiplex uplink control information (UCI) with a CG-UCI based on the determination, wherein the CG-UCI contains an indication whether a hybrid automatic repeat request acknowledgment HARQ-ACK or channel state information CSI is multiplexed; and
transmit, to a wireless system, the multiplexed UCI with the CG-UCI.

### Claim 16 (depends on 15)

The non-transitory computer-readable medium of claim 15, wherein the multiplexing comprises multiplexing the UCI with the CG-UCI on a CG physical uplink shared channel (PUSCH).
