An enhanced distributed power control algorithm for mobile femtocells under limited dynamic range and its convergence

摘要

This paper presents a distributed power control algorithm for wireless backhaul links of mobile femtocells by using the pilot's information. Taking into account the limited dynamic range of transmitted powers, the SINR balancing of mobile (vehicular) femto base stations in their home macro base station and the load balancing among the macrocells are achieved by the proposed approach at the cost of exchanging some limited information among both macro and vehicular femto base stations. The algorithm is very beneficial especially in a high load heterogeneous network. Monte Carlo simulation results denote that the mobile femtocells can be uniformly assigned to the macrocells and the SINR balancing is achievable via the proposed scheme.
