According to an embodiment of the present disclosure, a method performed by a first network node in a wireless communication system comprises: transmitting, to a second network node involving a dual connectivity (DC) with the first network node, a configuration for at least one measurement window; receiving, from the second network node, a result of a first measurement performed by the second network node during a measurement window among the at least one measurement window, and information for the measurement window; and combining the result of the first measurement and a result of a second measurement performed by the first network node during the measurement window identified by the information. ## Claims ### Claim 1 A method performed by a first network node in a wireless communication system, the method comprising: performing measurements during measurement windows; receiving, from a second network node, a result of a measurement performed by the second network node during a measurement window, and an index of the measurement window; identifying, based on the received index, a result of a measurement performed by the first network node during the measurement window having the index among the measurement windows; and combining the result of the measurement performed by the first network node during the measurement window and the result of the measurement performed by the second network node during the measurement window, wherein each of the measurement windows is determined based on a time offset from a reference timing to a start timing of an initial measurement window and a window length, and wherein the method further comprises transmitting, to the second network node, configuration information comprising the time offset and the window length. ### Claim 2 (depends on 1) The method of claim 1, further comprising: transmitting, to a third network node, information for the combined results of the measurement performed by the first network node during the measurement window and the measurement performed by the second network node during the measurement window. ### Claim 3 (depends on 1) The method of claim 1, wherein the each of the measurement windows is adjacent to each other in a time domain, and wherein the window length is a same for the at least one measurement windows. ### Claim 4 (depends on 1) The method of claim 1, wherein the reference timing comprises: a timing of a subframe 0 of a system frame number (SFN) 0 related to the first network node; or a timing of a subframe 0 of an SFN 0 related to the second network node. ### Claim 5 (depends on 1) The method of claim 1, further comprising: identifying a start time of the measurement window and an end time of the measurement window based on the received index. ### Claim 6 (depends on 1) The method of claim 1, further comprising: transmitting, to the second network node, configuration information comprising at least one of: an identifier (ID) of a measurement task identifying a type of a measurement required to be performed; a configuration for the measurement windows; an ID of a wireless device the first network node and the second network node communicate with; or a bearer identifier of a bearer on which a measurement is required to be performed. ### Claim 7 (depends on 1) The method of claim 1, further comprising: generating measurement entries each of which comprises at least one of: a result of a measurement performed by the first network node during a specific measurement window; and an index of the specific measurement window. ### Claim 8 (depends on 1) The method of claim 1, further comprising: obtaining measurement results based on the measurements performed by the first network node during the measurement windows; identifying, among the measurement windows, the measurement window during which the measurement is performed by the second network node based on the received index; and, identifying, among the measurement results, the result of the measurement performed by the first network node during the identified measurement window. ### Claim 9 (depends on 1) The method of claim 1, wherein the first network node and the second network node communicate with a wireless device in a dual connectivity (DC), and wherein the wireless device is in communication with at least one of a user equipment, a network, or autonomous vehicles other than the wireless device. ### Claim 10 (depends on 1) The method of claim 1, wherein the measurement window length is determined as a time duration during which a specific number of packets are received. ### Claim 11 A first network node in a wireless communication system, the first network node comprising: a transceiver; a memory; and at least one processor operatively coupled to the transceiver and the memory, and configured to: perform measurements during measurement windows; control the transceiver to receive, from a second network node, a result of a measurement performed by the second network node during a measurement window, and an index of the measurement window; identify, based on the received index, a result of a measurement performed by the first network node during the measurement window having the index among the measurement windows; and combine the result of the measurement performed by the first network node during the measurement window and the result of the measurement performed by the second network node during the measurement window, wherein each of the measurement windows is determined based on a time offset from a reference timing to a start timing of an initial measurement window and a window length, and wherein the method further comprises transmitting, to the second network node, configuration information comprising the time offset and the window length. ### Claim 12 A processor for a first network node in a wireless communication system, wherein the processor is configured to control the first network node to perform operations comprising: performing measurements during measurement windows; receiving, from a second network node, a result of a measurement performed by the second network node during a measurement window, and an index of the measurement window; identifying, based on the received index, a result of a measurement performed by the first network node during the measurement window having the index among the measurement windows; and combining the result of the measurement performed by the first network node during the measurement window and the result of the measurement performed by the second network node during the measurement window, wherein each of the measurement windows is determined based on a time offset from a reference timing to a start timing of an initial measurement window and a window length, and wherein the method further comprises transmitting, to the second network node, configuration information comprising the time offset and the window length.
