Abstract: This application provides a collaborative node-based positioning method, a to-be-positioned node, and a collaborative node. The method includes: obtaining a collaborative positioning node list corresponding to each collaborative node that can directly communicate with the to-be-positioned node; selecting, according to the collaborative positioning node list corresponding to each collaborative node, a collaborative node corresponding to a collaborative positioning node list in which a quantity of collaborative nodes being the same as that in a target list corresponding to the to-be-positioned node is largest; and performing positioning on the to-be-positioned node by using an anchor node and each monitoring node, where the anchor node is the selected collaborative node, and each monitoring node is each of same collaborative nodes between the collaborative positioning node list corresponding to the anchor node and the target list.

Abstract: Disclosed is an interference coordination method, a base station, and a high altitude platform station. The high altitude platform station receives information that includes a location of a base station and a radius of a central area of a coverage area of the base station, and calculates an interference start time and an interference end time according to the received information and a flight parameter of the high altitude platform station. The high altitude platform station sends interference coordination information to the base station, where the interference coordination information includes the interference start time, the interference end time, and a frequency band of a carrier used in both an edge area of a coverage area of the high altitude platform station and the central area of the coverage area of the base station. The base station adjusts the coverage area of the carrier according to the interference coordination information.
