Patent ID: 6904013

Claim:
CDMA base-station comprising a transmit stage ( 2 , 4 , 7 , 9 , 10 , 11 , 12 ) end a receive stage ( 3 , 5 , 8 , 13 ) for communicating with mobile terminals, the transmit stage comprising a power amplifier having at least two independent power modules ( 10 , 11 ) for transmitting signals on at least One traffic channel (TCH) end control and pilot signals on at least one control channel (CCH), each power module ( 10 , 11 ) being capable of being operational even though one other power module is non-operational, the at least two power modules normally being adapted for operating simultaneously and each contributing with emitting power, whereby the CDMA base station moreover comprises a control module ( 16 ) monitoring error status of the power modules in the base station, the control module carrying out an error routine, in which the following steps are undertaken, when an error signal is detected in the base-station indicative of an error in one of said power modules ( 10 , 11 ), immediately ending operation of all traffic channels associated with the erroneous power module ( 10 , 11 ), but sustaining operation of the at least one control channel (CCH); wherein when the control channel (CCH) is restored after a fault in one of said power modules has occurred, the base-station; disables the traffic channel power control (TPC ) power loop; deletes traffic for a predetermined group terminals; enables the TPC power loop; sets up communication with remaining terminals in sector; and allocates traffic channels (TCH) in sector to remaining terminals at a new reduced power level (Prmaxf).
