详细说明： Femtocells have been considered as a promising technology to provide better indoor coverage and spatial reuse gains in the last few years. Femtocells are low power, low cost and user deployed wireless access points that use local broadband connections as backhau l. Not only the users but also the operators benefit from femtocells. On the one hand, users enjoy high-quality links; on the other hand, operators decrease the operational expenditure (OPEX) and capital expenditure (CAPEX) due to the traffic offloading and user’s self-deployment of femtocell base stations (FBSs). Orthogonal frequency division multiple access (OFDMA) based femtocells have been considered in major wireless communication standards, e.g., LTE/LTE-Advanced. Due to spectrum scarcity and implementation difficulty, spectrum-sharing, rather than spectrumsplitting, between femtocells andmacrocells is more preferable from the operator’s perspective. However, co-channel deployed femtocells may lead to severe co-channel interference between femtocells in dense deployment, and cross-tier inference between macro-tier and femto-tier. ...展开收缩
