Although the almost blank subframes (ABSFs) proposed in heterogeneous cellular networks can enhance the performance of the cell range expansion (CRE) user equipments (UEs), it significantly degrades the macro-cell total throughput. To address this problem, the low power subframes (LPSFs) are encouraged to be applied in the macro-cell center region by the further-enhanced inter-cell interference coordination...
MAC interference in IEEE 802.11 network is caused by overlapped signal ranges and complex carrier sensing topology. Data throughput and wireless coverage increases by sender's transmission power in free space and this property identified the transmission power as a standard indication for wireless efficiency; however, increased transmission power also implies longer reachable signal range and higher...
