2.4 power control algorithm
2.4 power control algorithm Power control is to adjust the output power that can satisfy the reception of a called party and thus maximize the system capacity in the circumstances of dynamically changing channels, velocities of mobile stations, and call status. If an area where the mobile station is moving with path loss, background noise, or severe fading, its base station should assign more power to traffic channels. Perfect power control is impossible, however, because it cannot but have some errors due to the unbalance between the forward and reverse links, incorrect estimation of the status of channels, or delay of power control.
