摘要： An interference detection system includes a plurality of radio frame acquisition apparatuses and an interference detection apparatus. The interference detection apparatus includes radio frame information reception part, radio frame information storage part, simultaneous frame extraction part, and interference detection part. A radio frame information reception part receives the radio frame information transmitted from the radio frame acquisition apparatus. A radio frame information storage part stores the received radio frame information. A simultaneous frame extraction part extracts first radio frame, and second radio frame demodulated simultaneously or almost simultaneously with first radio frame. An interference detection part determines whether or not first radio frame and second radio frame are interfering with each other on the basis of whether or not there exists(exist) radio frame acquisition apparatus(es) which has(have) demodulated first radio frame and second radio frame simultaneously or almost simultaneously, among a plurality of the radio frame acquisition apparatuses.

摘要： A control apparatus predicts a probability distribution of radio quality when a downlink transmission from a base station to a radio terminal or an uplink transmission from a radio terminal to a base station is to be performed. The control apparatus calculates an expected value of a block error rate or reliability in the downlink or uplink transmission using the predicted probability distribution. The control apparatus determines a value of each of one or more parameters related to the downlink or uplink transmission, taking into account the calculated expected value.
