  Non-orthogonal unicast multicast (NOUM) is a variant of multi-antenna
multi-user communications where the users desire a shared message (multicast)
in addition to their respective unique messages (unicast). The multicast rate
is capped in many emerging NOUM applications, such as live-event broadcasting,
location-based services and vehicular communications. Given this constraint, we
experimentally show that when the user channels are highly correlated,
Rate-Splitting Multiple Access (RSMA)-based NOUM can meet the multicast rate
while supporting a larger unicast sum rate than multi-user linear precoding
(MULP)-based NOUM and orthogonal unicast multicast.
