Position-aided mobile communications

Capacity limits of position aware adaptive mobile communication systems exploiting channel state information (CSI) at the transmitter (CSIT) are presented. The position aware adaptive communication systems are benchmarked against state-of-the-art adaptive modulation and coding (AMC) systems that use only feedback CSI or additionally predict CSIT. Numerical results show that position aware adaptive systems achieve large capacity gains compared to state-of-the-art AMC systems for medium to large feedback delays.
