Abstract

Chapter 3 shows that for short-range UAC, the predicted instantaneous CSI feedback from the receiver to the transmitter can improve system performance considerably. However, as discussed in Sect. 2.3, for medium-long-range UAC, the propagation time of the feedback signal could be much larger than the coherence time and therefore nullify the instantaneous CSI feedback. In this chapter, statistical CSI is considered for the design of the medium-long-range RA-UAC system. We first present the AsAP protocol with instantaneous amplification at the relays and then investigate the power allocation among the source and the relays based on statistical CSI.
