ABSTRACT:
A cellular-telephone base station (12) services a cell (14) that encompasses cells (16 and 18) serviced by other base stations (20 and 22). The base station (12) associated with the overlaid cell (14) communicates with mobile stations within its cell (14) by way of code-division multiple-access (CDMA) channels in a first frequency band. The CDMA channels by which the other base stations (20 and 22) communicate with mobile stations in their respective cells (16 and 18) occupy a second frequency band. Although the two smaller-cell base stations (20 and 22) employ the same frequency band, they are not contiguous, and they are separated enough so that they interfere only negligibly. Consequently, their channel capacities exceed those of conventionally configured CDMA cells of the same bandwidth.
