Abstract

Disclosed are a method for improving measurement performance of a terminal in a wireless communication system, and an apparatus therefor. Specifically, in a method wherein a terminal performs measurement in a wireless communication system, a method performed by the terminal comprises the steps of: receiving, from a serving base station, configuration information for measurement of a reference signal receive power (RSRP) and/or a reference signal received quality (RSRQ), wherein the configuration information includes port configuration information related to an antenna port to which a reference signal is transmitted and measurement configuration information related to a correlation between a cell-specific reference signal (CRS) and a re-synchronization signal (RSS) for the measurement; receiving the CRS and/or the RSS from a neighbor base station; calculating the RSRP and/or the RSRQ according to the configuration information by using the CRS and the RSS; and reporting the RSRP and/or the RSRQ to the serving base station.

Claims (37)

1. A method of performing measurement at a terminal, in a wireless communication system, the method performed by the terminal comprising:

receiving, from a base station, configuration information related to a re-synchronization signal (RSS);

receiving the RSS from the base station; and

performing measurement of Reference Signal Received Power (RSRP) and/or Reference Signal Received Quality (RSRQ) using the RSS based on the configuration information,

wherein the configuration information includes a bitmap with one or more bits for indicating one or more narrow bands (NBs) used for a deployment of the RSS,

wherein three non-overlapping RSS locations are located in each of the one or more NBs, and

wherein RSS frequency locations of a specific cell are determined based on a modular operation using a cell identifier of the specific cell.

2. The method of claim 1 , wherein the RSS is mapped to a resource in units of two resource blocks (RB).

3. A terminal for performing measurement in a wireless communication system, the terminal comprising:

a transmitter for transmitting a radio signal;

a receiver for receiving a radio signal; and

a processor for controlling the transmitter and the receiver,

wherein the processor is configured to:

receive, from a base station, configuration information related to a re-synchronization signal (RSS);

receive the RSS from the base station; and

perform measurement of Reference Signal Received Power (RSRP) and/or Reference Signal Received Quality (RSRQ) using the RSS based on the configuration information,

wherein the configuration information includes a bitmap with one or more bits for indicating one or more narrow bands (NBs) used for a deployment of the RSS,

wherein three non-overlapping RSS locations are located in each of the one or more NBs, and

wherein RSS frequency locations of a specific cell are determined based on a modular operation using a cell identifier of the specific cell.

4. The terminal of claim 3 , wherein the RSS is mapped to a resource in units of two resource blocks (RB).

5. A method of transmitting a resynchronization signal (RSS) in a wireless communication system, the method performed by a base station and comprising:

transmitting, a terminal, configuration information related to the RSS; and

transmitting the RSS to the terminal,

wherein the configuration information includes a bitmap with one or more bits for indicating one or more narrow bands (NBs) used for a deployment of the RSS,

wherein three non-overlapping RSS locations are located in each of the one or more NBs, and

wherein RSS frequency locations of a specific cell are determined based on a modular operation using a cell identifier of the specific cell.

6. The method of claim 5 , wherein the RSS is mapped to a resource in units of two resource blocks (RB).

7. A base station for transmitting a re-synchronization signal (RSS) in a wireless communication system, the base station comprising:

a transmitter for transmitting a radio signal;

a receiver for receiving a radio signal; and

a processor for controlling the transmitter and the receiver,

wherein the processor is configured to:

transmit, a terminal, configuration information related to the RSS; and

transmit the RSS to the terminal,

wherein the configuration information includes a bitmap with one or more bits for indicating one or more narrow bands (NBs) used for a deployment of the RSS,

wherein three non-overlapping RSS locations are located in each of the one or more NBs, and

wherein RSS frequency locations of a specific cell are determined based on a modular operation using a cell identifier of the specific cell.
