Claim 0:
1. A quality estimation system for estimating downlink (DL) throughput at user terminals which are connected to a wireless network, the quality estimation system comprising:
a processor programmed to execute a process including
acquiring at least terminal information, wireless reception quality information, and network quality information from a plurality of user terminals;
deriving coefficients in an estimation equation in which the DL throughput is an objective variable and at least the wireless reception quality information and the network quality information are explanatory variables, based on the acquired terminal information, wireless reception quality information, and network quality information;
estimating DL throughput corresponding to measurement data from the measurement data using the estimation equation with application of the coefficients,

wherein the terminal information includes transmission scheme information comprising information indicative of lower performance between information on a transmission scheme at a base station and information on a transmission scheme at a user terminal of the plurality of user terminals, and
wherein the transmission scheme information is utilized in deriving the coefficients.
