Abstract
Provided in the present invention is a method for avoiding downlink interference between an indoor DAS system and a small base station, the steps comprising: step 1: determining an initial access RU, and establishing a signal strength table; step 2: the DAS system, by means of the chosen RU, attempts to establish a downlink with UE 1, and detects the signal to interference plus noise ratio (SINR) value of the downlink signal of UE 1, and comparing same with a preset threshold value γ1; step 3: UE 1 maintains one or a plurality of RU downlinks assigned thereto by the DAS system, during the communication process continuously detects an SINR value at a set time interval, and on the basis of whether same is greater than γ1, ensures a corresponding service quality.
