Abstract Joint transmission (JT), a novel downlink transmission scheme, was introduced and described in recent papers. Questions still open concern the performance assessment of JT and the comparison of JT with conventional downlink transmission schemes. In order to answer these questions, quantities termed SNR degradation and transmission efficiency are presented in this paper. Based on these quantities, exemplary system assessments and comparisons are performed, which clearly show the suitability of these measures and also the advantages of the novel downlink transmission scheme JT.
