Interference Management and Traffic Adaptation of Femto Base Station based on TD-LTE
نویسندگان
چکیده
As a mainstream technology in the 4G systems, TD-LTE (Time Division-Long Term Evolution) introduces Femto nodes to improve spectral efficiency per unit area. However, inter-cell cross-slot interference and uplink/downlink configuration are the key problems in TDD (Time Division Duplexing) system. In the paper, a traffic adaptation scheme with consideration of traffic demands and interference level is proposed to select optimal uplink/downlink configuration and efficiently improves system capacity.

Novel Interference Avoidance Approach for Femtocell Networks
Short range, low power, plug and play femtocell improves indoor service availability with higher data rate, better voice quality, extended cell edge coverage, network traffic offloading and negligible greenhouse gas emissions. However, due to frequency reuse, edge macrocell users are subjected to severe uplink interference from co-channel deployed femtocell in the same province. Transmit power ...
متن کاملA Review Paper on Improvement of Coexistence of LTE Femtocell Network with Dynamic Resource Allocation
A cognitive femtocell is a new small cell based on a smart home base station to solve the spectrum-scarcity problem. Recently, dedicated resource allocation for cognitive femtocells is extensively researched to mitigate the co-channel interference. However, the cognitive femtocell may suffer from the lack of frequency resource for its users due to high data traffic load of the macro cell. Inter...

The Long Ter...
متن کاملHeterogeneous LTE Networks and Inter-Cell Interference Coordination
Initial deployments of LTE networks are based on so-called homogeneous networks consisting of base stations providing basic coverage, called macro base stations. The concept of heterogeneous networks has recently attracted considerable attention to optimize performance particularly for unequal user or traffic distribution. Here, the layer of planned highpower macro eNBs is overlaid with layers ...
