On the Power Control Due to Em Radiation from Uplink Power and the Interference Management in Ea Td-lte Systems

The rapid evolution of digital mobile data services exerted a need for serious thrust on more efficient ways to address the harmful effects of electromagnetic radiation due to the Uplink power of the mobile terminal on the human body. The Specific Absorption Rate (SAR) value is the standard dosimetric parameter in defining the energy absorbed by the human body exposed to EM radiation. Increase in multimedia services and the wide scale use of various applications like web browsing, real-time video and interactive games have resulted in the EA between the uplink and downlink. We present a procedural approach for the evaluation of the Electromagnetic (EM) Radiation influence of the interaction of the mobile terminal with the human body. Electromagnetic Asymmetry (EA) means that, under the restriction of EM radiation, the equivalent bandwidth of uplink should be narrower than that of downlink in view of the duplexing schemes. Time Division Long Term Evolution (TD-LTE) is meant to utilize dynamic Time division duplex(TDD) and adjust its service for the fast changes in Downlink(DL) and Uplink(UL)traffic Asymmetry. But the same subframe will have different DL/UL will have different DL/UL directions in neighboring cells leading to interference between different base stations and user equipments. A versatile UL power control scheme is proposed in the context of EM radiation and interference both occurring due to EM Asymmetry.
