ABSTRACT:
A first control channel associated with a first cell is communicated in the first cell using a first time/frequency window. The first control channel and a traffic channel are communicated in a second cell using the first time/frequency window. The first control channel may be communicated in the second cell when the first time/frequency window is unassigned to a traffic channel in the second cell. The first time/frequency window may be assigned to a traffic channel in the second cell, and the first control channel may be communicated in the second cell when the traffic channel to which the first time/frequency window is assigned in the second cell is idle. The traffic channel to which the first time/frequency window is assigned in the second cell may be communicated over different carrier frequency bands to thereby frequency hop the traffic channel. The second cell may be served by a base station, and a traffic channel may be communicated between the base station and a radiotelephone using the first time/frequency window at a signal power level which decreases as the distance between the base station and the radiotelephone decreases.
