## Abstract

A method for handling a resource collision is performed by a user equipment (UE). The method includes: determining at least one time domain unit corresponding to an overlapping resource between a resource for repetitions of a first uplink message and a resource of a physical channel for a second uplink message, wherein the first uplink message is msg.3 and the second uplink message is msg.1 or msg.A; and not sending the first uplink message and the second uplink message simultaneously on the at least one time domain unit.

not sending the first uplink message on the at least one time domain unit.

### Claim 4 (depends on 2)

The method according to claim 2, wherein determining the at least one time domain unit corresponding to the overlapping resource between the resource for repetitions of the first uplink message and the resource of the physical channel for the second uplink message comprises:
determining a first resource in a set of resources used for sending the second uplink message; and
determining a second resource in the set of resources, wherein a synchronization signal block (SSB) index mapped by the second resource is the same as a SSB index mapped by the first resource; and
determining at least one time domain unit corresponding to an overlapping resource between the second resource and the resource for repetitions of the first uplink message.

### Claim 5 (depends on 4)

The method according to claim 4, further comprising:
receiving configuration information sent by a network device, wherein the configuration information indicates the set of resources used for sending the second uplink message.

### Claim 6 (depends on 1)

The method according to claim 1, further comprising: determining an invalid random access channel (RACH) occasion (RO) in the resource of the physical channel, wherein the at least one time domain unit comprises the invalid RO;
wherein not sending the first uplink message and the second uplink message simultaneously on the at least one time domain unit comprises:
in response to not sending the second uplink message at the invalid RO, sending the first uplink message at the invalid RO.

### Claim 7 (depends on 6)

The method according to claim 6, wherein determining the invalid RO in the resource of the physical channel comprises:
receiving an invalid resource mode from a network device, wherein the invalid resource mode indicates the invalid RO.

### Claim 8 (depends on 6)

The method according to claim 6, wherein an invalid resource mode is determined by the network device based on the invalid RO,
a first RO resource is determined in a set of RO resources used by the first UE for sending the second uplink message, and a second RO resource in the set of RO resources is determined as the invalid RO, wherein a synchronization signal block (SSB) index mapped by the second RO resource is the same as a SSB index mapped by the first RO resource.

### Claim 9 (depends on 1)

The method according to claim 1, wherein the physical channel for the second uplink message comprises at least one of: a physical random access channel (PRACH), or a physical uplink shared channel (PUSCH).

### Claim 10

A method for handling a resource collision, performed by a network device, comprises:
determining at least one time domain unit for a user equipment (UE) corresponding to an overlapping resource between a resource for repetitions of a first uplink message and a resource of a physical channel for a second uplink message, wherein the first uplink message is msg.3 and the second uplink message is msg.1 or msg.A; and
in response to not sending the first uplink message and the second uplink message simultaneously on the at least one time domain unit by the UE, receiving one of the first uplink message or the second uplink message on the at least one time domain unit.
