The invention discloses a method and a
system for controlling uplink and downlink power, which relate to the field of
wireless communication and can reduce the outdoor interference caused by indoor communication. According to the invention, according to downlink
signal sampling data of an adjacent
cell, a downlink interference control threshold corresponding to an indoor
cell is calculated; according to the downlink
signal sampling data of the indoor
cell, an uplink interference control threshold corresponding to the indoor cell is calculated; during
power control, judgment for downlink and / or
downlink transmission power is implemented on a terminal inside the indoor cell, if the
downlink transmission power of network side to the terminal is larger than the downlink interference control threshold according to the
power control judgment result after the
power control, power adjustment is not performed according to the judgment result, instead, the
downlink transmission power of the terminal is adjusted to the downlink interference control threshold. And if the
uplink transmission power of the terminal is larger than the uplink interference control threshold according to the power control judgment result after the power control, the
uplink transmission power of the terminal is adjusted to the uplink interference control threshold.
