Design Considerations for Radio Resource Management of LTE/LTE-A Femtocells

In order to improve the wireless network performance, one of the most potential solutions is the use of a number of small size cells called femtocells. One of the facilitating technologies for LTE/ LTE-A (Long Term EvolutionAdvance) is the deployment of femtocellular network. As the number of femtocell increases, managing the radio resource becomes challenging due to the co existence of other femtocells and the macro cells. Also with the development of radio access techniques, the radio resource is becoming insufficient. Therefore, it is turning out to be a vital issue that how should the demands for higher data rates with limited resources is met for the evolving 4G network. Radio Resource Management (RRM) techniques involve controlling factors such as transmit power, allocation of channel, handover strategies, guarantee of data rates etc. This paper aims to highlight the RRM considerations with the perspective of LTE/ LTE-A femtocells with OFDMA radio access technology, the broader objective being to emphasize on the importance of efficient RRM techniques.
