Abstract
A method for operating a base station to service data communications in a cell/sector of a digital cellular wireless system. Data user forward link transmit power within the cell/sector is allocated. A data user Fundamental Channel (FCH) forward link transmit power reserve level upper limit (fd,max) and a data user FCH forward link transmit power reserve lower limit (fd,min) are set. A data user FCH forward link transmit power reserve level (fd) is initialized. The base station is operated to allocate FCHs to data users within the cell/sector, deallocate FCHs to data users within the cell/sector, allocate SCHs to data users within the cell/sector, and to deallocate SCHs to data users within the cell/sector. The SCHs are allocated so that the data user FCH forward link transmit power reserve level is maintained. Based upon at least one current data user operating condition in the cell/sector fd is adjusted. Operation prevents fd from violating fd,max or fd,min.
