4.2.13 Power Control Bits (PCB)
In CDMA networks, control of the Mobile Station (MS) transmit power is essential to
ensure stable transmission and an efficient radio resource management within the sys-
tem. Generally speaking an output power of the MS transmitter that is too low decrea-
ses the coverage area while an excess output power may cause interference to other
channels or systems. Both effects decrease the system capacity.
Within CDMA2000 systems, the Power Control Bits (PCB) are used to request the
increase or reduction in transmit power from the MS. A series of these power control
bits is sent on the traffic channel instead of the scrambled data bits. The MS receives
the PCB commands and adjusts its transmit power. One to four data bits (depending
on the data rate) are replaced by the corresponding number of PCBs ("0...0" or "1...1").
