Classification: CPC H | IPC H

Claim 10:
11. The base station of claim 9, wherein the at least one processor is configured to:
calculate conditional covariance matrixes to identify whether the plurality of UEs transmit a signal using pilot signal matrixes of the plurality of UEs;
obtain a hypothesis testing function representing a log-likelihood ratio using the conditional covariance matrixes, the likelihood function, and the sample covariance matrix; and
detect the user index set including user indexes of the plurality of UEs including the at least one UE to allow a log-likelihood ratio indicated by the obtained hypothesis testing function to have a maximum value, and wherein respective user indexes of the plurality of UEs have a binary vector value of 0 or 1 depending on whether to transmit a signal.
