System for scheduling reverse-channel messages in narrowband communications systems and methods of operation

摘要

A communications controller is disclosed for use in a wireless communication system having a plurality of antennas capable of simulcasting forward-channel messages at a first downtilt angle below horizon and receiving reverse-channel messages at a second downtilt angle, wherein the second downtilt angle is less than the first downtilt angle. The communications controller, which is associated with the plurality of antennas, is capable of (i) scheduling transmission of ones of the reverse-channel messages at a same frequency in a same time slot, and (ii) receiving reverse-channel messages of two communication units proximate a local antenna at separate more remote antennas in response to the second downtilt angle of the separate more remote antennas.
