Abstract
The present invention provides a method for resisting small base station uplink signal interference of an indoor DAS based on antenna selection. The method comprises: step 1: determining an initial access RU, and establishing an uplink; step 2: determining, by the access RU of UE 1 on the basis of the level of interference, whether to switch to another RU, and continuously detecting, by the access RU of UE 1 an SINR value at a set time interval, and comparing the SINR with a preset threshold value γ1; wherein if the SINR value is lower than γ1, an MU sets the access RU and each peripheral RU as a candidate RU, and the MU, on the basis of the acquired SINR value of each RU, selects an SINR greater than γ1 and sets the RU having the greatest receiving signal power as the new access RU of UE 1.
