Abstract :
The UMTS Long Term Evolution (LTE) allows the pilot symbol power to be adjusted with respect to that of the data symbols. In this paper, we derive optimal pilot power allocation in multi-cell scenarios under imperfect channel knowledge at the terminals. As cost function, we choose the post-equalization Signal to Interference and Noise Ratio (SINR). We show via simulations that this cost function indeed leads to maximum throughput.
