Abstract
Integrated Access and Backhaul (IAB) technology standardized by the 3GPP provides the possibility to significantly reduce the cost of 5G New Radio deployments. The authors study the transmission delay in dense urban areas operating in the millimeter frequency range. The proposed system model allows for buffering analysis at transit IAB-nodes using the queuing theory and includes parameterization of the radio channel using the methods of stochastic geometry. The numerical experiment showed that the system performance in terms of packet delay and resource utilization is determined mainly by road traffic conditions and not by the coverage area of IAB-nodes.
