| description | This study investigates how to adjust the transmit power of femto base station (FBS) to mitigate interference problems between the
FBSs and mobile users (MUs) in the 2-tier heterogeneous femtocell
networks. A common baseline of deploying the FBS to increase the
indoor access bandwidth requires that the FBS operation will not
affect outdoor MUs operation with their quality-of-service (QoS)
requirements. To tackle this technical problem, an FBS
transmit power adjustment (FTPA) algorithm is proposed to adjust
the FBS transmit power (FTP) to avoid unwanted cochannel
interference (CCI) with the neighboring MUs in downlink
transmission. FTPA reduces the FTP to serve its femto users (FUs)
according to the QoS requirements of the nearest neighboring MUs
to the FBS so that the MU QoS requirement is guaranteed.
Simulation results demonstrate that FTPA can achieve a low MU
outage probability as well as serve FUs without violating the MU
QoS requirements. Simulation results also reveal that FTPA has
better performance on voice and video services which are the major
trend of future multimedia communication in the NGN. |
