the pathloss is calculated in the function link_quality_model in +network_elements/UE.m
RSRP/RSRQ are not included in the simulator. The cell assignment is calculated based on the strongest received power in LTE_common_calculate_cell_capacity.m
regarding the pathloss, i mean how can i read the value of UE pathloss (in dB) , after running any demo. because i searched in UE traces but never find the value of the pathloss for each UE.
the path loss maps are not stored in the traces to save memory.
You can change that by modifying the traces in +tracing and the saving of the results in LTE_sim_main.m
