An anti small indoor base station an uplink signal interference method based on antenna selection system das

The present invention provides a method of a small base station an uplink signal interference anti indoor DAS system based on antenna selection, comprising the step of: Step 1: determining an initial access RU, establishes uplink; Step 2: RU UE1 access interference level is determined in accordance with whether to switch the other RU, RU access the UE1 a certain time interval duration detection SINR value, and compared with a preset threshold value [gamma] l, [gamma] l if the SINR value is less than, the respective access a MU RU RU and the periphery thereof as RU candidates, according to a MU RU SINR value of each of the obtained selection SINR is greater than [gamma] l, and the received signal power as the maximum RU RU UE1 new access. Advantageous effects of the present invention is: (1) without coordination mechanism between the DAS and the small base station system (sharing information), reduce the requirements for the feedback link.
