Method for multicasting messages to users of a wireless communication
system includes the steps of establishing a power ratio threshold for
transmitting the messages, measuring respective power ratios of the
users, comparing the established power ratio threshold to the measured
power ratios, determining a first subset of the users and a second subset
of the users based upon the measured power ratios and delivering the
messages to the first subset of the plurality of users via a first
transmission scheme. The first transmission scheme delivers the messages
to all of the users of the first subset via a broadcast channel. The
method also has a step of delivering the messages to the second subset of
the users via a second transmission scheme. The second transmission
scheme delivers the messages to each of the users of the second subset
via respective dedicated channels.
