Abstract	The LTE-based femtocell network is a promising solution adopted today to cope with the huge cellular traffic requirements. In particular, the Uplink communication becomes an attractive issue especially with the emerging of the interactive services and large uploaded data volume. Intelligent allocation of the resources and interference management are the main challenges in such context. In this paper, we propose a linear optimization model for the SC-FDMA Uplink transmission aiming to adaptively allocate resources with respect to the link quality. Both power and modulation and coding schemes are independently assigned to each user over each allocated sub-channel. The cluster architecture is adopted as a hybrid centralized/distributed network. The user differentiation strategy ensures the QoS guarantee with respect to a priority level of each user. Taking into account the specifications of the uplink communication, we confirm through comparative simulations the outperformance of our proposal considering several metrics such as throughput satisfaction rate, transmitted power, outage probability, special spectrum reuse and others.
