Embodiments of the present invention provide a method for suppressing uplink background noise in an indoor distributed system, a device, and a system, including: acquiring, by a gain adjustment device, carrier-level uplink user power of a remote coverage unit in a co-cell and carrier-level uplink user power of the rest of remote coverage units in the co-cell; determining, by the gain adjustment device, a carrier-level weighting factor of the remote coverage unit according to the carrier-level uplink user power of the remote coverage unit and the carrier-level uplink user power of the rest of remote coverage units in the co-cell; and adjusting, by the gain adjustment device, a carrier-level uplink receive gain of the remote coverage unit according to the carrier-level weighting factor of the remote coverage unit, where the carrier-level uplink receive gain of the remote coverage unit is less than 0. Because the carrier-level uplink receive gain is less than 0, power of uplink background noise after combination can be reduced, thereby achieving an objective of reducing uplink background noise that exists after combination. |
