Abstract
A downlink channel quality information acquisition method includes: a transmission node in a coordinated node set acquires the noise receiving power of a user equipment (UE11) and the interference power on the UE11 of a node in a non-coordinated set; the transmission node in the coordinated node set acquires, via the transmission node in the coordinated node set, an inter-user interference power during the multi-user scheduling and the effective signal receiving power of the UE11; the transmission node in the coordinated node set acquires the interference power on the UE11 of a non-transmission node in the coordinated set; calculating the ratio between the effective signal receiving power and the sum of an interference source power and the noise receiving power of the UE11, and using the ratio as the value of the downlink CQI between the transmission node and the UE11.
