Table 6 Detection performance in terms of required SNR in dBs for 90% detection probability, when using either uniformly distributed gNB delays as in [12] or propagation delay based gNB grouping for the proposed scheme A. Here, a fixed number of simultaneously transmitting gNBs, \(M_{\text {gNB}} = 80\), is assumed
