1. A method for performing a Minimization of Driver Test (MDT) by a first wireless communication node, comprising:
receiving a first message from a second wireless communication node; and
determining at least one of the following: a data packet discard rate and a packet discard delay according to the first message,
wherein the first message comprises a MDT configuration, wherein the MDT configuration indicates a determination of at least one of the following: the data packet discard rate and the packet discard delay, and wherein the MDT configuration comprises at least one of the following: a measurement period and a first Packet Delay Budget (PDB),
wherein the packet discard rate is a ratio between a number of discarded packets and a total number of packets, wherein each of the packets is one of the following on a corresponding layer in at least one delay-critical Quality of Service (QoS): a downlink (DL) packet and an uplink (UL) packet, wherein the at least one delay-critical QoS is determined according to one of the following: QoS information carried by a Data Radio Bearer (DRB) and packet information of a QoS, wherein the discarded packets comprises at least one Radio Link Control (RLC) segment, wherein the at least one RLC segment is not transmitted to the wireless communication device within a second PDB, and wherein the discarded packets each is one of the following: a first packet and a second packet, wherein the first packet is one of the packets discarded, and wherein the second packet is one of the packets labeled as discarded and being transmitted.
