Method for transmitting and receiving downlink data in wireless communication system, and apparatus therefor
First Claim
1. A method for transmitting and receiving a downlink (DL) data in a wireless communication system, the method performed by a user equipment (UE) comprising:
- receiving a first DL grant from a base station (BS);
receiving, from the BS, a first DL data based on the first DL grant;
transmitting, to the BS, a HARQ response in response to the first DL data; and
receiving a second DL data from the BS,wherein the first DL data and the second DL data are received through a frequency region allocated by the first DL grant,wherein a specific frequency shift pattern in the frequency region is configured in a frequency region i) between a resource in which the second DL data is received and a resource in which the first DL data is received, or ii) between resources in which the second DL data is received, andwherein a Physical Resource Block (PRB) index sequence of a DL data is shifted from a PRB index sequence of a previous DL data, based on a shift value configured by the specific frequency shift pattern.

Abstract
A method for transmitting and receiving downlink (DL) data performed by a user equipment (UE) in a wireless communication system according to the present disclosure includes receiving a first DL grant from a base station (BS); receiving first DL data based on the first DL grant from the BS; transmitting a HARQ response in response to the first DL data to the BS; and receiving one or more second DL data from the BS, and a specific frequency shift pattern is set in a frequency region between a resource in which the second DL data is received and a resource in which the first DL data is received, or between resources in which the second DL data are received.

20. A user equipment (UE) for transmitting and receiving a downlink (DL) data in a wireless communication system, comprising:
-
a radio frequency (RF) transceiver for transmitting and receiving a radio signal; and a processor functionally connected to the RF transceiver, wherein the processor is configured to; receive a first DL grant from a base station (BS); receive, from the BS, a first DL data based on the first DL grant; transmit, to the BS, a hybrid automatic repeat request (HARQ) response in response to the first DL data; and receive a second DL data from the BS, wherein the processor is configured to receive the first DL data and the second DL data through a frequency region allocated by the first DL grant, wherein a specific frequency shift pattern in the frequency region is configured i) between a resource in which the second DL data is received and a resource in which the first DL data is received, or ii) between resources in which the second DL data is received, and wherein a Physical Resource Block (PRB) index sequence of a DL data is shifted from a PRB index sequence of a previous DL data, based on a shift value configured by the specific frequency shift pattern.
