Abstract


In order to adapt to the needs of future mobile communication system broadband in this demand driven , the 3GPP ( Third Generation Partnership Project), on the basis of 3G (third generation mobile communications) , the start of the next - generation mobile communication systems LTE ( Long Term Evolution ), research and development, China has also launched the next generation of mobile communication systems , research and development of TD-LTE , launch LTE project in order to provide a lower transmission delay and higher data transfer rates , wider frequency bandwidth and more good QOS ( Quality of Service) wireless communication technology . The main contents of this paper is based on the TD-LTE system uplink power control algorithm . Detailed description of basic knowledge and uplink key technologies of LTE and LTE FDD uplink power control algorithm is introduced , based on the classic target SINR (Signal to Interference plus Noise Ratio ) and detailed closed-loop power control algorithm this algorithm is given on the basis of this algorithm , and verify the correctness of the algorithm in TD-LTE system . In addition, the uplink power control is also an effective LTE inter-cell interference suppression technology, existing LTE cell interference suppression technology based on an SFR ( soft frequency reuse ) and uplink power control integration technology as TD-LTE inter-cell interference suppression technology .
