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: transmitting uplink data from a user device (UE) to a network device over a wireless uplink channel;measuring transmission power of the uplink channel and thereby generating transmission power information;obtaining transmission Quality of Service (QoS) information of the uplink channel;correlating the transmission power information with the transmission QoS information and generating a correlation result of an uplink performance of the UE; andidentifying a performance problem of the UE based on the correlation result. 2. The method of claim 1, wherein the transmission QoS information comprises at least one of a data rate, a transport block size, a modulation and coding scheme, a transmission bandwidth, a number of resource blocks, a number of soft combinations or network macro diversity, a signal strength or quality, and an interference level. 3. The method of claim 1, wherein the transmission power information comprises at least one of an absolute transmission power measured, a power headroom report, an indicator indicating that the UE is power limited, and implicit power information deduced based on a power control command or a defined UE power control behavior. 4. The method of claim 1, wherein the UE archives the correlation result of the transmission power information and the transmission QoS information in a UE metrics log. 5. The method of claim 4, further comprising: reporting the UE metrics log to the network device. 6. The method of claim 4, wherein the archiving into the log is conditional based on a condition corresponding to a network performance problem. 7. The method of claim 6, wherein the condition being a low data rate and the UE is power limited. 8. A method, comprising: receiving, by a network device, uplink data from a user device (UE) over an uplink channel in a wireless network;receiving transmission power information from the UE;obtaining transmission Quality of Service (QoS) information;correlating the transmission power information with the transmission QoS information and generating a correlation result of an uplink performance of the UE; andidentifying a performance problem of the UE based on the correlation result. 9. The method of claim 8, wherein the transmission QoS information comprises at least one of a data rate, a transport block size, a modulation and coding scheme, a transmission bandwidth, a number of resource blocks, a number of soft combinations or network macro diversity, a signal strength or quality, and an interference level. 10. The method of claim 8, wherein the transmission power information comprises at least one of an absolute transmission power measured, a power headroom report, an indicator indicating that the UE is power limited, and implicit power information deduced based on a power control command or a defined UE power control behavior. 11. The method of claim 8, wherein the network device archives the correlation result of the transmission power information and the transmission QoS information in a network metrics log. 12. The method of claim 11, further comprising: receiving a UE correlation metrics log that comprises another correlation result of the transmission power information and the transmission QoS information generated by the UE. 13. The method of claim 12, wherein the network metrics log further includes the UE correlation metrics log. 14. A user equipment (UE), comprising: a transceiver that transmits uplink data to a network device over a wireless uplink channel;an uplink power measurement controller that measures transmission power of the uplink channel and thereby generating transmission power information;a Quality of Service (QoS) generator that obtains QoS information of the uplink channel; anda correlator that correlates the transmission power information and the transmission QoS information, generates a correlation result of an uplink performance of the UE, and identifies a performance problem of the UE based on the correlation result. 15. The UE of claim 14, wherein the transmission QoS information comprises at least one of a data rate, a transport block size, a modulation and coding scheme, a transmission bandwidth, a number of resource blocks, a number of soft combinations or network macro diversity, a signal strength or quality, and an interference level. 16. The UE of claim 14, wherein the transmission power information comprises at least one of an absolute transmission power measured, a power headroom report, an indicator indicating that the UE is power limited, and implicit power information deduced based on a power control command or a defined UE power control behavior. 17. The UE of claim 14, further comprising: a memory that stores the correlation result of the transmission power information and the transmission QoS information in a UE metrics log. 18. The UE of claim 17, wherein the transceiver reports the UE metrics log to the network device. 19. The UE of claim 17, wherein the storing into the log is conditional based on a condition corresponding to a network performance problem. 20. The UE of claim 19, wherein the condition being a low data rate and the UE is power limited. 21. The UE of claim 14, further comprising: a configurator, wherein the configurator configures a correlation algorithm for the correlation module.
