## Abstract

A method and apparatus for allocating resources for a sidelink transmission in a wireless communication system is provided. A user equipment (UE) selects a first carrier, i.e. anchor carrier, among multiple carriers, and allocates a first resource on the first carrier. The UE allocates a second resource on a second carrier, i.e. non-anchor carrier, based on an offset from the first resource on the first carrier. The UE performs the sidelink transmission by using the first resource on the first carrier and the second resource on the second carrier.

## Claims

### Claim 1

A method for allocating resources for a sidelink transmission by a user equipment (UE) in a wireless communication system, the method comprising:
selecting a first carrier among multiple carriers;
allocating a first resource on the first carrier;
allocating a second resource on a second carrier, among the multiple carriers except the first carrier, based on an offset from the first resource on the first carrier; and
performing the sidelink transmission by using the first resource on the first carrier and the second resource on the second carrier.

### Claim 2 (depends on 1)

The method of claim 1, wherein the offset is configured by a network.

### Claim 3 (depends on 1)

The method of claim 1, wherein the offset is one of a time offset or a frequency offset.

### Claim 4 (depends on 1)

The method of claim 1, wherein the second resource is allocated from the first resource by the offset, and
wherein the offset is fixed.

### Claim 5 (depends on 4)

The method of claim 4, wherein the offset is same for carriers among the multiple carriers except the first carrier.

### Claim 6 (depends on 4)

The method of claim 4, wherein the offset is different for carriers among the multiple carriers except the first carrier.

### Claim 7 (depends on 4)

The method of claim 4, wherein the offset is same for carriers in a same frequency band.

### Claim 8 (depends on 4)

The method of claim 4, wherein the offset is different for carriers in different frequency bands.

### Claim 9 (depends on 4)

The method of claim 4, wherein the offset changes in every resource reservation interval.

### Claim 10 (depends on 1)

The method of claim 1, wherein the second resource is randomly allocated within an interval from the first resource on the first carrier by the offset.

### Claim 11 (depends on 1)

The method of claim 1, wherein the offset is a value which is selected between a maximum offset value and a minimum offset value.

### Claim 12 (depends on 11)

The method of claim 11, wherein the maximum offset value and the minimum value is configured by a network.

### Claim 13 (depends on 1)

The method of claim 1, wherein the offset changes according to a channel busy ratio (CBR) of the second carrier.

### Claim 14 (depends on 1)

The method of claim 1, wherein the first resource is configured by a network.

### Claim 15 (depends on 1)

The method of claim 1, wherein the UE is in communication with at least one of a mobile device, a network, and/or autonomous vehicles other than the UE.

### Claim 16

A user equipment (UE) in a wireless communication system, the UE comprising:
a memory;
a transceiver; and
a processor, operably coupled to the memory and the transceiver, that:
selects a first carrier among multiple carriers;
allocates a first resource on the first carrier;
allocates a second resource on a second carrier, among the multiple carriers except the first carrier, based on an offset from the first resource on the first carrier; and
controls the transceiver to perform the sidelink transmission by using the first resource on the first carrier and the second resource on the second carrier.
