## Abstract

A user equipment (UE) for receiving information on a length of a reference signal (RS) sequence and information on an offset of the RS sequence and performing an RS sequence mapping to map the RS sequence to a physical resource block 0 (PRB0) of the UE within a bandwidth part (BWP) based on the length of the RS sequence and the offset of the RS sequence. The UE also transmits, to the network, the RS sequence.

## Claims

### Claim 1

A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
receiving, from a network, information on a length of a reference signal (RS) sequence and information on an offset of the RS sequences;
performing an RS sequence mapping to map the RS sequence to a physical resource block 0 (PRB0) of the UE within a bandwidth part (BWP) based on the length of the RS sequence and the offset of the RS sequence; and
transmitting, to the network, the RS sequence,
wherein the length of the RS sequence and the offset of the RS sequence are used for the RS sequence mapping based on that:
the PRB0 of the UE is different from that of another UE within the BWP so that a common PRB indexing is unused for the RS sequence mapping.

### Claim 2 (depends on 1)

The method of claim 1, wherein multiple RS sequences including the RS sequence are generated over a system bandwidth.

### Claim 3 (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 4

A user equipment (UE) in a wireless communication system, the UE comprising:
a memory;
a transceiver; and
at least one processor, operably coupled to the memory and the transceiver, configured to:
control the transceiver to receive, from a network, information on a length of a reference signal (RS) sequence and information on an offset of the RS sequence,
perform an RS sequence mapping to map the RS sequence to a physical resource block 0 (PRB0) of the UE within a bandwidth part (BWP) based on the the length of the RS sequence and the offset of the RS sequence, and
control the transceiver to transmit, to the network, the RS sequence,
wherein the length of the RS sequence and the offset of the RS sequence are used for the RS sequence mapping based on that:
the PRB0 of the UE is different from that of another UE within the BWP so that a common PRB indexing is unused for the RS sequence mapping.

### Claim 5 (depends on 4)

The UE of claim 4, wherein multiple RS sequences including the RS sequence are generated over a system bandwidth.

### Claim 6

A method performed by a base station (BS) in a wireless communication system, the method comprising:
transmitting, to a user equipment (UE) information on a length of a reference signal (RS) sequence and information on an offset of the RS sequence; and
receiving, from the UE, the RS sequence,
wherein the RS sequence is mapped to a physical resource block 0 (PRB0) of the UE within a bandwidth part (BWP) according to an RS sequence mapping, and
wherein the length of the RS sequence and the offset of the RS sequence are used for the RS sequence mapping based on that:
the PRB0 of the UE is different from that of another UE within the BWP so that a common PRB indexing is unused for the RS sequence mapping.

### Claim 7 (depends on 6)

The method of claim 6, wherein multiple RS sequences including the RS sequence are generated over a system bandwidth.
