The embodiment of the invention discloses a subframe allocation method, a processing method and a device. The subframe allocation method comprises the following steps: searching for available nodes on a subframe tree when a subscriber reference signal (SRS) is configured with a subframe; and selecting an available node from the available nodes as an SRS subframe configuration node of the subscriber. In the embodiment of the invention, the subframe configuration is performed on the SRS of the subscriber based on the structure of the subframe tree and the identification of the subframe tree node, thus avoiding conflict when the subframe configuration is performed on the SRSs of different subscribers, and improving the success rate of the subframe configuration; furthermore, the structure based on the subframe tree can be flexibly expanded and contracted according to the subframe configuration condition, thus improving the subframe configuration performance of a system.
