Apparatus and method for measurement in wireless communication system
The present disclosure relates to a pre-5 th -Generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4 th -Generation (4G) communication system such as long-term evolution (LTE). The disclosure relates to the collection and reporting of measurement information in a wireless communication system, in which an operation method of a terminal may include receiving configuration information for a logged minimization drive test (MDT) disclosed by a secondary node (SN), storing a measurement result by performing the logged MDT in one of a radio resource control (RRC) idle mode or an RRC inactive mode, based on the received configuration information, transmitting a message including an indicator for indicating that the stored measurement result exists after the terminal is switched to the RRC connected mode, receiving a request message for requesting the logged MDT measurement result, and transmitting a message for reporting the logged MDT measurement result.
1. A method performed by a secondary node (SN) in a wireless communication system, the method comprising:
receiving, from a master node (MN), configuration information for an immediate minimization of drive test (MDT);
transmitting, to a terminal, the configuration information; and
receiving, from the terminal, an immediate MDT measurement result,
wherein the terminal is in a radio resource control (RRC) connected mode when the MDT measurement result is measured,
wherein a first radio access technology (RAT) of the MN is different from a second RAT of the SN, and
wherein the terminal communicates with the MN and the SN.
2. The method of claim 1 ,
wherein the immediate MDT measurement result received from the terminal is received through the MN.
3. The method of claim 1 , further comprising forwarding the immediate MDT measurement result to a master node (MN) in order to transmit the immediate MDT measurement result received from the terminal to a trace collection entity (TCE) server.
4. The method of claim 1 , further comprising transmitting the immediate MDT measurement result received from the terminal to a trace collection entity (TCE) server.
5. A method performed by a terminal in a wireless communication system, the method comprising:
receiving, from a secondary node (SN), configuration information for an immediate minimization of drive test (MDT); and
transmitting, to the SN, an immediate MDT measurement result,
wherein the terminal is in a radio resource control (RRC) connected mode when the immediate MDT measurement result is measured,
wherein a first radio access technology (RAT) of a master node (MN) is different from a second RAT of the SN, and
wherein the terminal communicates with the MN and the SN.
6. The method of claim 5 , wherein the configuration information for the immediate MDT received from the SN is received through a master node (MN), and
wherein the immediate MDT measurement result is transmitted to the SN through the MN.
7. A secondary node (SN) in a wireless communication system, the SN comprising:
a transceiver; and
at least one processor operably coupled to the transceiver,
wherein the at least one processor is configured to:
receive, from a master node (MN), configuration information for an immediate minimization of drive test (MDT),
transmit, to a terminal, the configuration information, and
receive, from the terminal, an immediate MDT measurement result,
wherein the terminal is in a radio resource control (RRC) connected mode when the immediate MDT measurement result is measured,
wherein a first radio access technology (RAT) of the MN is different from a second RAT of the SN,
wherein the terminal communicates with the MN and the SN.
8. The SN of claim 7 , wherein the at least one processor is further configured to:
transmit the configuration information for the immediate MDT to the terminal through a master node (MN), and
receive the immediate MDT measurement result received from the terminal through the MN.
9. The SN of claim 7 , wherein the at least one processor is further configured to:
forward the immediate MDT measurement result to a master node (MN) in order to transmit the immediate MDT measurement result received from the terminal to a trace collection entity (TCE) server.
10. The SN of claim 7 , wherein the at least one processor is further configured to:
transmit the immediate MDT measurement result received from the terminal to a trace collection entity (TCE) server.
11. A terminal in a wireless communication system, the terminal comprising:
a transceiver; and
at least one processor operably coupled to the transceiver,
wherein the at least one processor is configured to:
receive, from a secondary node (SN) configuration information for an immediate minimization of drive test (MDT), and
transmit, to the SN, an immediate MDT measurement result,
wherein the terminal is in a radio resource control (RRC) connected mode when the immediate MDT measurement result is measured,
wherein a first radio technology (RAT) of a master node (MN) is different from a second RAT of the SN, and
wherein the terminal communicates with the MN and the SN.
12. The terminal of claim 11 , wherein the at least one processor is further configured to:
receive the configuration information for the immediate MDT received from the SN through a master node (MN), and
