## Abstract

A method for providing a V2X service in a next generation wireless access technology (New RAT) comprises: receiving sidelink control information transmitted from other terminal through a sidelink control channel; and receiving sidelink data information transmitted by the other terminal on a sidelink data channel configured in the same slot based on the sidelink control information, wherein the sidelink control information and the sidelink data information are received in N same symbols among 14 symbols constituting the same slot, and the sidelink data information is received in all of the 14 symbols.

## Claims

### Claim 1

A method of performing a vehicle communication by a terminal, the method comprising:
receiving sidelink control information transmitted from other terminal through a sidelink control channel;
receiving sidelink data information transmitted by the other terminal on a sidelink data channel configured in the same slot based on the sidelink control information; and
transmitting response information indicating whether or not the sidelink data information is normally received, to the other terminal,
wherein the sidelink control information and the sidelink data information are received in N same symbols among 14 symbols constituting the same slot, and the sidelink data information is received in all of the 14 symbols,
wherein in case of the sidelink data information is group cast type, there is determined whether to transmit the response information based on distance information between the other terminal and the terminal,
wherein the sidelink control information comprises location information of the other terminal.

### Claim 2 (depends on 1)

The method according to claim 1, wherein the N same symbols in which both the sidelink control information and the sidelink data information are received are symbols allocated from symbol indexes 0 to N−1.

### Claim 3 (depends on 2)

The method according to claim 2, wherein frequency bands in which the sidelink control information and the sidelink data information are received in the N same symbols are different from each other.

### Claim 4 (depends on 1)

The method according to claim 1, wherein the sidelink control information is received through some frequency bands of the frequency bands allocated in the same symbol, and the sidelink data information is received in a frequency band other than some of the frequency bands in the allocated frequency bands.

### Claim 5 (depends on 4)

The method according to claim 4, wherein, when the allocated frequency bands are from X Hz to Y Hz, some of frequency bands are allocated from K Hz to Z Hz,
wherein K is a number greater than X, and Z is a number less than Y, and X, Y, K, Z is a natural number.

### Claim 6 (depends on 1)

The method according to claim 1, wherein the distance information between the other terminal and the terminal is calculated based on the location information of the other terminal.

### Claim 7

A terminal performing a vehicle communication, the terminal comprising:
a receiver receiving sidelink control information transmitted from other terminal through a sidelink control channel, and sidelink data information transmitted by the other terminal on a sidelink data channel configured in the same slot based on the sidelink control information;
a controller decoding the sidelink control information and the sidelink data information; and
a transmitter transmitting response information indicating whether or not the sidelink data information is normally received, to the other terminal,
wherein the sidelink control information and the sidelink data information are received in N same symbols among 14 symbols constituting the same slot, and the sidelink data information is received in all of the 14 symbols,
wherein in case of the sidelink data information is group cast type, the controller determines whether to transmit the response information based on distance information between the other terminal and the terminal,
wherein, the sidelink control information comprises location information of the other terminal.

### Claim 8 (depends on 7)

The terminal according to claim 7, wherein the N same symbols in which both the sidelink control information and the sidelink data information are received are symbols allocated from symbol indexes 0 to N−1.

### Claim 9 (depends on 8)

The terminal according to claim 8, wherein frequency bands in which the sidelink control information and the sidelink data information are received in the N same symbols are different from each other.

### Claim 10 (depends on 7)

The terminal according to claim 7, wherein the sidelink control information is received through some frequency bands of the frequency bands allocated in the same symbol, and the sidelink data information is received in a frequency band other than some of the frequency bands in the allocated frequency bands.

### Claim 11 (depends on 10)

The terminal according to claim 10, wherein, when the allocated frequency bands are from X Hz to Y Hz, some of frequency bands are allocated from K Hz to Z Hz,
wherein K is a number greater than X, and Z is a number less than Y, and X, Y, K, Z is a natural number.

### Claim 12 (depends on 7)

The terminal according to claim 7, wherein the distance information between the other terminal and the terminal is calculated based on the location information of the other terminal.
