Millimeter-wave network deployment is an essential and ongoing problem due to the limited coverage and expensive network infrastructure. In this work, we solve a joint network deployment and resource allocation optimization problem for a mmWave cell-free massive MIMO network considering indoor dense spaces (IDSs). The objective is to minimize the deployed access points (APs) for a given environment and given radio resources (e.g. bandwidth, AP cooperation) while guaranteeing the rate requirements of the user equipment (UEs). Considering coherent joint transmission (C-JT) and non-coherent joint transmission (NC-JT), we develop several algorithms that can be used for different-sized environments. We later analyze the effect of functional split and demonstrate the trade-off between the fronthaul rate and the complexity of an AP. For numerical analysis, we model a mid-sized airplane cabin in ray-tracing as an exemplary case for IDS. The numerical analysis demonstrates that UEs can achieve higher than 1 Gbps data rates while deploying less than 10 APs with C-JT. We observe an above 600 Gbps fronthaul rate once all network operations are centralized, demonstrating the significance of efficient network deployment for mmWave communications. ; QC 20231030
