Abstract

A method for transmitting, by a terminal, an uplink signal in a wireless communication system according to one embodiment of the present disclosure comprises the steps of: receiving, from a base station, scheduling request (SR) resource information and data resource information; transmitting an SR through any one of a UE-wise SR resource and a group-wise SR resource allocated through the SR resource information; and repeatedly transmitting uplink data through a plurality of resource areas allocated through the data resource information, wherein one UE-wise SR resource may be allocated to each first resource area set consisting of N resource areas, and at least one group-wise SR resource may be allocated to each resource area. The UE is capable of communicating with at least one of another UE, a UE related to an autonomous driving vehicle, a base station or a network.

First claim

The invention claimed is:

1. A method for transmitting an uplink signal by a user equipment (UE) in a wireless communication system, the method comprising:
receiving scheduling request (SR) resource information and data resource information from a base station, wherein the SR resource information comprises UE-wise SR resource allocation information and group-wise SR resource allocation information;
selecting a UE-wise SR resource for transmission of an SR;
transmitting the SR through the selected UE-wise SR resource allocated through the SR resource information; and
repeatedly transmitting uplink data through a plurality of resource zones allocated through the data resource information,
wherein a resource zone set includes N (N is a natural number) resource zones having different locations in the time domain,
wherein only one UE-wise SR resource is allocated to a resource zone set, and at least one group-wise SR resource is allocated to each of the N resource zones, and
wherein the repeated transmission of the data starts from a start time of the resource zone set based on the selection of the UE-wise SR resource.

2. The method of claim 1 , wherein the UE selects the UE-wise SR resource based on a time when the uplink data is generated.

3. The method of claim 1 , further comprising:
receiving, from the base station, information indicating one of a non-staggering mode and a staggering mode, wherein start and end times of the repeated transmission are matched with start and end times of the resource zone set in the non-staggering mode, and do not match the start and end times of the resource zone set in the staggering mode.

4. The method of claim 3 ,
wherein, the start and end times of the repeated transmission of the UE are configured to be the same as other UEs, and
wherein, according to the staggering mode, the start and end times of the repeated transmission of the UE are configured independently from the other UEs.

5. A method for receiving an uplink signal by a base station in a wireless communication system, the method comprising:
transmitting scheduling request (SR) resource information and data resource information to a user equipment (UE), wherein the SR resource information comprises UE-wise SR resource allocation information and group-wise SR resource allocation information;
receiving an SR through a UE-wise SR resource allocated through the SR resource information; and
repeatedly receiving uplink data through a plurality of resource zones allocated through the data resource information,
wherein a resource zone set includes N (N is a natural number) resource zones having different locations in time domain,
wherein only one UE-wise SR resource is allocated to a resource zone set, and at least one group-wise SR resource is allocated to each of the N resource zones, and
wherein the repeated reception of the data coincides with a start time of the resource zone set based on the use of the UE-wise SR resource.

6. The method of claim 5 , wherein the UE-wise SR resource is selected based on a time when the uplink data is generated.

7. The method of claim 5 , further comprising:
transmitting information indicating one of a non-staggering mode and a staggering mode, wherein start and end times of the repeated transmission are matched with start and end times of the resource zone set in the non-staggering mode, and do not match the start and end times of the resource zone set in the staggering mode.

8. The method of claim 7 ,
wherein, the start and end times of the repeated transmission of the UE are configured to be the same as other UEs, and
wherein, according to the staggering mode, the start and end times of the repeated transmission of the UE are configured independently from the other UEs.

9. A user equipment (UE) for transmitting an uplink signal in a wireless communication system, comprising:
a transmitter;
a receiver; and
a processor configured to receive scheduling request (SR) resource information and data resource information from a base station using the receiver, wherein the SR resource information comprises UE-wise SR resource allocation information and group-wise SR resource allocation information, to select a UE-wise SR resource for transmission of an SR; to transmit the SR through the selected UE-wise SR resource allocated through the SR resource information using the transmitter, and to repeatedly transmit uplink data through a plurality of resource zones allocated through the data resource information using the transmitter,
wherein a resource zone set includes N (N is a natural number) resource zones having different locations in time domain,
wherein only one UE-wise SR resource is allocated to a resource zone set, and at least one group-wise SR resource is allocated to each of the N resource zones, and
wherein the repeated transmission of the data starts from a start time of the resource zone set based on the selection of the UE-wise SR resource.

10. A base station for receiving an uplink signal in a wireless communication system, comprising:
a transmitter;
a receiver; and
a processor configured to transmit scheduling request (SR) resource information and data resource information to a user equipment (UE) using the transmitter, wherein the SR resource information comprises UE-wise SR resource allocation information and group-wise SR resource allocation information, to receive an SR through a UE-wise SR resource allocated through the SR resource information using the receiver, and to repeatedly receive uplink data through a plurality of resource zones allocated through the data resource information,
wherein a resource zone set includes N (N is a natural number) resource zones having different locations in time domain,
wherein only one UE-wise SR resource is allocated to a resource zone set and at least one group-wise SR resource is allocated to each of the N resource zones, and
wherein the repeated reception of the data coincides with a start time of the resource zone set based on the use of the UE-wise SR resource.

11. The UE according to claim 9 , wherein the UE is capable of communicating with at least one of another UE, a UE related to an autonomous driving vehicle, a base station or a network.
