© 2017 IEEE. This paper studies Strict Frequency Reuse algorithm in uplink Stochastic Geometry networks which can be utilised to improve the spectrum efficiency in Long Term Evolution (LTE) networks by dividing the users into Cell-Center Users (CCUs) and Cell-Edge Users (CEUs). In this paper, we defined a two-phase operation of FR for both CCU and CEU in which each user is classified as either CCU or CEU according to the uplink signal strength on the uplink control channel during the first phase and data transfer between the user and it's serving Base Station during the second phase. The performance of the user, i.e. CCU and CEU, as well as the network system in Strict Frequency Reuse network with multi-users and multi-Resource Blocks (RBs) are derived. The analytical results which are verified by Monte Carlo simulation indicate that when SNR or SINR threshold increases, the system performance reaches the peak before steadily decreasing. Thus, the optimal value of SNR and SINR threshold are selected to maximise the performance of the network system.
