Description

LTE operation in unlicensed spectrum bands, based on Licensed-Assisted Access (LAA), is considered as an option to increase the capacity of 4G wireless networks. These solutions use a Listen Before Talk (LBT) protocol that enables the eNodeB (eNB) to access the medium opportunistically, avoiding collisions from/to other eNBs. However, the hidden node problem must be addressed in LAA networks to reduce or prevent the degradation of the network. The efficiency of the LTE-LAA system will improve by identifying hidden nodes and after deciding if user equipment (UE) affected by the hidden condition should remain or should change from unlicensed to licensed band. This dataset includes the simulation data of the performance parameters RSSI, RSRQ, RSRP, and CQI for nodes in hidden (overlapped) zone and free of collisions areas for a LTE-LAA network. The simulations were carried out in NS-3. Also, we include the code of two supervised machine learning algorithms, logistic regression, and a neural network to determine if UEs located in the border cell are affected by hidden nodes.
