In this letter we propose per antenna superposition
coding (PASC) by which partial information can be relayed
instead of full information, to exploit the higher capacity of
source-relay-destination link. Here, the PASC is designed across
antennas, producing basic layer and superposed layer for each
data stream per antenna. It is shown that an overall data rate
of partial information relaying with PASC can be increased
beyond that offered by full information relaying by virtue of
fast forwarding of partial information over relatively better link.
