Abstract


In order to meet the growing demand for mobile communication technology , 3GPP organization beginning of the third generation mobile communication (3G) of Long Term Evolution LTE (Long Term Evolution). 3G Long Term Evolution plans to increase the data transfer rate and reduce system latency , while increasing the coverage and system capacity , which can reduce user costs and operator costs and improving quality of service targets. 3GPP LTE system uses orthogonal frequency division multiplexing OFDM (Orthogonal Frequency Division Multiplexing) multi- access technique , because of their orthogonality between subcarriers , which can effectively prevent the interference users in the cell , so that so how to suppress the inter-cell interference as a study site . In order to better coordinate programs for interference studies, we established the LTE uplink system simulation platform , the simulation platform is designed mainly based on the 3GPP TR 25.814 , etc. 3GPP Technical Report Series . It also made ??reference to the major focus of communication research institutions and Communications Conference in 3GPP proposal , through these technical reports and proposals to read and understand , gave myself a lot of inspiration, these on paper LTE uplink system simulation platform design and system performance study has important guiding significance. Power as a wireless communication important resource is the entry point for this study , this paper range from small to explore how the power control level of interference suppression system and improving service performance edge users . Studied in this inter-cell power control scheme is that the user 's body from a service point of view , the different properties of the cell to classify users to explore different properties of the user for the different power control scheme , in order to achieve the interference reducing system level, to improve the quality of service purposes edge users .
