Methods of MDT information logging and reporting are provided. In one embodiment, a method is provided to resolve shortcomings of prior art by correlating UL measurements with QoS information to enable UL performance analysis and accurate detection of coverage problems. In another embodiment, a method is provided to resolve the shortcomings of the prior art by making DL measurements and location information collecting or logging conditional on UL measurements.

1. A method comprising: detecting an availability of an uplink (UL) measurement result by a user equipment (UE) in a wireless network;triggering a location-related performance and a downlink-related performance upon the detection of the availability of the UL measurement result;obtaining the uplink measurement result, a location-related measurement result and a downlink measurement result based on the location-related performance and the downlink-related performance; andcorrelating the location-related measurement result, the downlink measurement result and the uplink measurement results for a performance test for the UE. 2. The method of claim 1, wherein the location-related performance is a location-related measurement and the downlink-related performance is a downlink measurement are performed or recorded when the uplink measurement result becomes available. 3. The method of claim 1, wherein the location-related performance is to log one or more location-related measurement result into a log and the downlink-related performance is to log one or more downlink measurement result into the log. 4. The method of claim 3, further comprising: transmitting the log to a network device. 5. A method comprising: detecting an availability of a first uplink (UL) measurement result applicable to a user equipment (UE), by a network device in a wireless network;performing a location-related performance and a downlink-related performance based on the availability of the first UL measurement result;performing a second uplink measurement applicable to the UE and thereby generating a second uplink measurement result upon detecting the availability of the first UL measurement result;obtaining a location-related measurement result, downlink measurement result, and the first uplink measurement result; andcorrelating the location-related measurement result, the downlink measurement result, the first uplink measurement result, and the second uplink measurement result for a performance test for the UE. 6. The method of claim 5, wherein the first UL measurement result is not detected and the location-related performance is to discards one or more location-related measurement result and the downlink-related performance is to discard one or more downlink measurement result non-relevant to uplink in a logging process. 7. The method of claim 5, wherein the correlation is triggered when the first uplink measurement result becomes available. 8. The method of claim 7, wherein the network receives the location-related measurement result from the UE when the first uplink measurement result becomes available. 9. The method of claim 5, wherein the correlation is triggered when an UL/DL transmission is available or when it becomes known to the network that data is present in a transmission or re-transmission buffer. 10. The method of claim 9, wherein the network receives the location-related measurement result from the UE when the UL/DL transmission is performed. 11. A user equipment (UE) comprising: a radio frequency transceiver that transmits uplink signals and receives downlink signal;a measurement module that detecting an availability of an uplink (UL) measurement result triggers a location-related performance and a downlink-related performance upon the detection of the availability of the UL measurement result, obtains location-related measurement result, downlink measurement result, and the uplink measurement result; anda correlator that correlates the location-related measurement result, the downlink measurement result and the uplink measurement result for a performance test for the UE. 12. The UE of claim 11, wherein the location-related performance is a location-related measurement and the downlink-related performance is a downlink measurement. 13. The UE of claim 11, wherein the location-related performance is to log one or more location-related measurement result into a log, and the downlink-related performance is to log one or more downlink measurement result into the log. 14. The UE of claim 13, further comprising: a transmitter that transmits the log to a network device.
