  Coded caching (CC) schemes exploit the cumulative cache memory of network
users, outperforming traditional uncoded schemes where cache contents are only
used locally. Interestingly, this CC gain can also be combined with the spatial
multiplexing gain of multi-antenna transmissions. In this paper, we extend the
existing results of CC-aided data delivery in multi-access point (AP) wireless
local area networks (WLAN) and video streaming applications by assuming
multi-antenna transmitters at AP nodes. We present two distinct methods for
using the extra resource that multi-antenna transmitters provide. While the
first method tries to reduce the number of interference links in the network
graph, the second one aims to remove inter-stream interference so that users
with similar cache contents can be served simultaneously. While both methods
provide increased throughput, they differ significantly in the underlying
concept. Numerical simulations are used to compare the performance of different
methods.
