Embodiments of the present invention can be used to efficiently transmit
access control and traffic information on separate spatial channels. In
one embodiment, the invention includes assigning a conventional channel
and a first training sequence to a first remote radio and a second
training sequence to a second remote radio. Thereafter, the invention can
include communicating with the first remote radio on a first spatial
channel occupying the conventional channel using the first training
sequence, and communicating with the second remote radio on a second
spatial channel occupying the same conventional channel using the second
training sequence.
