Interference-Aware Muting for the uplink of heterogeneous cellular networks: A stochastic geometry approach

In this work, it is studied the performance of a scheduling algorithm where the Mobile Terminals (MTs) may be turned off if they cause a level of interference greater than a given threshold. This approach, which is referred to as Interference Aware Muting (IAM), may be regarded as an interference-aware scheme that is aimed to reduce the level of interference. The performance of IAM is studied in terms of transmit power, coverage probability, Spectral Efficiency (SE), and Binary Rate (BR). Simplified expressions of SE and BR for adaptive modulation and coding schemes are proposed, which better characterize practical communication systems. Our analysis unveils that, compared with conventional power control schemes, IAM increases the BR and reduces the transmit power.
