OFDMA based - Long - term evolution (LTE) femtocells represent a very promising answer to the ever rising bandwidth demand of mobile applications. Femtocells, standardised as HeNBs, are end user deployed network nodes for indoor environment with a network backhaul provided by the digital subscriber line (DSL) or cable modem. The base station called as Femtocell Access Point can be easily deplo yed in adhoc manner . Femtocells improve the coverage in indoor scenarios and provide better user experien ce, thereby increasing the network capacity. Resource allocation strategies play a key role in distributing radio resources among different stations, with fine time and frequency resolutions by taking into consideration the channel conditions as well as Qo S requirements. The present paper provides perform ance comparisons of radio resource scheduling strategies such as Proportional - Fair (PF), Modified Largest Weighted Delay First (MLWDF), Exponential Rule, Exponential/PF (EXP/PF), LOG Rule and Frame Level Sc heduler (FLS) with stress on QoS provisioning capabilities in the context of heterogeneous urban scenario with both macro and femtocells .
