Methods, apparatus and systems for configuring minimization of drive test under a multi-connectivity architecture

A method performed by a first wireless communication node being or comprising a first base station, the method comprising:

• transmitting, to a second wireless communication node being or comprising a second base station, a request for a minimization of drive test, MDT, measurement, wherein the first wireless communication node and the second wireless communication node are both nodes in a wireless network, and wherein the MDT measurement is to be executed by a wireless communication device in the wireless network;
• receiving, from the second wireless communication node, a configuration message for the MDT measurement;
• and
• transmitting, to the second wireless communication node, a feedback in response to the configuration message, the feedback comprising a conflict indication indicating that the first wireless communication node has triggered an existing MDT measurement, which is same as the MDT measurement, on the wireless communication device,
• wherein the second wireless communication node stops the MDT measurement at the second wireless communication node in response to the feedback.

A method performed by a first wireless communication node being or comprising a first base station, the method comprising:

• receiving, from a second wireless communication node being or comprising a second base station, configuration information for a minimization of drive test, MDT, measurement, wherein the first wireless communication node and the second wireless communication node are both nodes in a wireless network;
• and
• transmitting, to the second wireless communication node, a feedback in response to the configuration information for the MDT measurement,
• wherein the feedback comprises a confirmation of the configuration information for the MDT measurement and the second wireless communication node executes the MDT measurement based on the configuration information via a wireless communication device in the wireless network, or
• wherein the MDT measurement is executed by a wireless communication device in the wireless network;
• the feedback comprises a conflict indication indicating that the first wireless communication node has triggered an existing MDT measurement, which is same as the MDT measurement, on the wireless communication device;
• and
• the second wireless communication node stops the MDT measurement in response to the feedback.

A method performed by a first wireless communication node being or comprising a first base station, the method comprising:

• receiving, from a second wireless communication node being or comprising a second base station, a request for a minimization of drive test (MDT) measurement, wherein the first wireless communication node and the second wireless communication node are both nodes in a wireless network;
• transmitting, to the second wireless communication node, a configuration message for the MDT measurement, and wherein the MDT measurement is to be executed by a wireless communication device in the wireless network;
