In this work, we consider an energy harvesting device (EHD) served by an\naccess point with a single antenna that is used for both wireless power\ntransfer (WPT) and data transfer. The objective is to maximize the expected\nthroughput of the EHD over a finite horizon when the channel state information\nis only available causally. The EHD is energized by WPT for a certain duration,\nwhich is subject to optimization, and then, EHD transmits its information bits\nto the AP until the end of the time horizon by employing optimal dynamic power\nallocation. The joint optimization problem is modeled as a dynamic programming\nproblem. Based on the characteristic of the problem, we prove that a time\ndependent threshold type structure exists for the optimal WPT duration, and we\nobtain closed form solution to the dynamic power allocation in the uplink\nperiod.\n
