Abstract: Disclosed in the present invention are a method and an apparatus for antenna management. The method comprises that resource use status data are collected from managed access networks, access networks which participate antenna scheduling are selected from the managed access networks according to the resource use status data to compose an antenna scheduling set, wherein access networks using same spectrum resources are composed in the same antenna scheduling set; radio links of each access network in the antenna scheduling set are divided into one or more radio link clusters; radio resources are allocated to every radio link cluster in the antenna scheduling set in order that mutual interferences among all the radio link clusters in said antenna scheduling set are within a preset range; and radio resource allocation results are sent to the access network that the radio link clusters belong to. The said method and apparatus enable as many access networks as possible to work at the same time within an interference allowed range using the same spectrum resource, increasing spectrum multiplex opportunity and realizing high resource use rate.
