Classification: CPC H  G | IPC G  H

Claim 0:
1. A method for user selection, comprising:
for a whole set of candidate terminal devices, performing scheduling by:
obtaining a set of received signals;
determining a set of measurements for relevance among the candidate terminal devices based at least on the set of received signals and channel estimation for the set of candidate terminal devices, wherein determining the set of measurements for relevance is iteratively performed at least once until an iteration number is equal to a predetermined number and comprises:
determining residue between each received signal and its corresponding output of an artificial neuron network (ANN), having an input layer and an output layer, each of row vectors of a stream channel matrix being an input of the ANN, each of the receiving signals being an output of the ANN, an activation function for a neuron of the output layer being a linear activation function, the stream channel matrix being a product of a channel estimation matrix and a receiving beamforming matrix for the set of candidate terminal devices,
determining the set of measurements for relevance based on the residue, and
updating a set of weights of the ANN based on a gradient descent algorithm;

determining a maximum relevance measurement in the set of measurements; and
updating the set of candidate terminal devices by removing a candidate terminal device associated with the maximum relevance measurement from the set of candidate terminal devices.
