after a maximum noise rise for a cell is set , a maximum noise rise for each mobile station is allocated within the cell . the actual noise rise from each mobile station within the cell is measured at a base station and signaled to a network . when the cell uses enhanced dedicated channel , the contribution to noise rise of e - dch signaling is determined and received signal code power at the base station is measured . the rscp measurement is decoded to determine contributions from mobile stations within and outside the cell ; contributions from mobile stations within the cell are calculated ; and the network is notified of the measured noise rise . in addition a compensation value may be applied to compensate for temperature induced noise .
