Abstract
Disclosed are a method for reporting a measurement result by a terminal in a coverage expansion area in a wireless communication system and a device for supporting same. The terminal can receive a measurement configuration from a network, measure a cell, and report to the network measurement state information and a measurement result of the measured cell. The measurement state information can comprise information which indicates whether the cell has been measured in a coverage enhancement (CE) mode or a normal mode.

A method for reporting, by a user equipment (UE) in a coverage enhancement area, a measurement result in a wireless communication system, the method comprising:
- receiving a measurement configuration including period information, a predefined first RSRP threshold for a first CE level and a predefined second RSRP threshold for a second CE level, from a network,
- wherein the period information informs the UE that a cell is to be measured only in a coverage enhancement (CE) mode during a certain time duration included in the period information;
- measuring the cell in the CE mode or a non-CE mode, based on the period information,
- wherein the cell is measured for a longer time in the CE mode than in the non-CE mode,
- wherein the cell is measured in the first CE level, when an RSRP of the cell measured by the UE exceeds the first RSRP threshold,
- wherein the cell is measured in the second CE level, when the RSRP of the cell measured by the UE is the first RSRP threshold or lower, and when the RSRP of the cell measured by the UE exceeds the second RSRP threshold,
- wherein the first RSRP threshold is greater than the second RSRP threshold, and
- wherein the second CE level has a wider range of enhanced coverage than the first CE level;
- reporting the measurement result of the measured cell to the network;
- and
- reporting measurement state information including first information which informs the network whether the cell is measured in the CE mode or the non-CE mode, to the network.
A user equipment (UE) reporting a measurement result in a wireless communication system, the UE comprising:
- a memory;
- a transceiver;
- and
- a processor to connect the memory and the transceiver, wherein the processor is configured to:
- control the transceiver to receive a measurement configuration including period information, a predefined first RSRP threshold for a first CE level and a predefined second RSRP threshold for a second CE level, from a network,
- wherein the period information informs the UE that a cell is to be measured only in a coverage enhancement (CE) mode during a certain time duration included in the period information;
- measure the cell in the CE mode or a non-CE mode, based on the period information, wherein the cell is measured for a longer time in the CE mode than in the non-CE mode,
- wherein the cell is measured in the first CE level, when an RSRP of the cell measured by the UE exceeds the first RSRP threshold,
- wherein the cell is measured in the second CE level, when the RSRP of the cell measured by the UE is the first RSRP threshold or lower, and when the RSRP of the cell measured by the UE exceeds the second RSRP threshold,
- wherein the first RSRP threshold is greater than the second RSRP threshold, and
- wherein the second CE level has a wider range of enhanced coverage than the first CE level;
- control the transceiver to report the measurement result of the measured cell to the network;
- and
- control the transceiver to report measurement state information including first information which informs the network whether the cell is measured in the CE mode or the non-CE mode, to the network.
