  This paper presents results from the (to our knowledge) first dynamic
double-directionally resolved measurement campaign at mm-wave frequencies for
an outdoor microcellular scenario. The measurements are performed with USC's
real-time channel sounder equipped with phased array antennas that can steer
beams electrically in microseconds, allowing directional measurements in
dynamic environments. Exploiting the phase coherency of the setup, the
multi-path components can be tracked over time to investigate the temporal
dependencies of the channel characteristics. We present results for
time-varying path-loss, delay spread, mean angles and angular spreads observed
at the transmitter (TX) and receiver (RX) in the presence of moving vehicles
and pedestrians. Additionally, we investigate excess losses observed due to
blockage by vehicles and compare the cases when TX and RX are using fixed beams
or when they are capable of adjusting beam directions dynamically.
