Simulation and research of TD-LTE power control algorithm

Uplink power control is a key radio resource management function. It is typically used to maximize the power of the desired received signals while limiting the generated interference. This paper presents the 3GPP long Term Evolution (LTE) power control mechanism, and compares its performance to two reference mechanisms. TD-LTE communications systems are interference limitation systems, The use of power control technology demonstrate the superiority of TD-LTE. Power control is the key technology Resource Allocation Management and interference management, The effective Power Control algorithm reduce the mutual interference of UE, In the case of satisfying the quality of communication of each user, Minimize the emission power, So as to reduce interfere, increase the capacity of system, prolong the standby time of mobilephone.
