## Abstract

A UE receives a first indication of a Wake-Up Signal (WUS) resource for another UE. The UE identifies a conflict between a resource allocated to the UE and the WUS resource for the other UE based on the first indication. The UE modifies communication with a base station in the resource in response to the identifying of the conflict. A base station identifies a conflict between a resource for communication with a first UE and a WUS for another UE and modifies the communication with the first UE in the resource in response to identifying the conflict.

## Claims

### Claim 1

A method of wireless communication at a User Equipment (UE), comprising:
receiving a first indication of a Wake-Up Signal (WUS) resource for a second UE;
receiving, prior to the WUS resource, a second indication indicating at least one of whether to puncture reception of a communication, whether to rate-match around the WUS resource, or a schedule of one or more resources that at least partially overlap the WUS resource;
identifying a conflict between a resource allocated to the UE and the WUS resource for the second UE based on the first indication; and
modifying the communication with a base station in the resource based on the second indication and in response to identifying the conflict.

### Claim 2 (depends on 1)

The method of claim 1, wherein the resource is for a downlink data transmission or a downlink control transmission.

### Claim 4 (depends on 2)

The method of claim 2, wherein modifying the communication in the resource includes rate-matching around the WUS resource.

### Claim 5 (depends on 4)

The method of claim 4, wherein the first indication is comprised in a rate-matching resource configuration parameter.

### Claim 6 (depends on 2)

The method of claim 2, wherein modifying the communication includes puncturing the reception of the communication or rate-matching the communication based on the second indication.

### Claim 7 (depends on 6)

The method of claim 6, wherein the second indication is received in downlink control information (DCI).

### Claim 8 (depends on 2)

The method of claim 2, wherein modifying the communication in the resource includes receiving the communication based on the schedule.

### Claim 9 (depends on 8)

The method of claim 8, wherein modifying the communication further includes puncturing the reception of the communication based on the schedule.

### Claim 10 (depends on 8)

The method of claim 8, wherein modifying the communication further includes rate-matching around a respective resource based on the schedule.

### Claim 11 (depends on 8)

The method of claim 8, wherein the schedule indicates shifted locations in at least one of time or frequency for the communication based on the conflict between the one or more resources and the WUS resource, and
wherein modifying the communication includes monitoring for the communication at the shifted locations.

### Claim 12 (depends on 1)

The method of claim 1, wherein the communication comprises a downlink reference signal.

### Claim 13 (depends on 12)

The method of claim 12, wherein the downlink reference signal includes one of a channel state information reference signal (CSI-RS), a phase tracking reference signal (PTRS), a tracking reference signal, and a demodulation reference signal (DMRS).

### Claim 14 (depends on 13)

The method of claim 13, wherein modifying the communication includes receiving the downlink reference signal using puncturing on the WUS resource or rate-matching around the WUS resource.

### Claim 15 (depends on 13)

The method of claim 13, wherein the schedule indicates a shifted location of the downlink reference signal, and
wherein modifying the communication includes monitoring for the downlink reference signal at the shifted location.

### Claim 16 (depends on 13)
