    Abstract: A positioning method and a corresponding terminal and system. A terminal acquires positioning information of the terminal, and sends the acquired positioning information to a first transmission node, the positioning information comprising at least one type of the following information: signal strength information, a subframe or subframe set index, channel characteristic information, access point information and environment characteristic information. The first transmission node transmits the positioning information to a positioning service system, and the positioning service system acquires the positioning information reported by the terminal and determines a geographic position of the terminal according to the positioning information. The present invention can satisfy related enhanced positioning demands.

    Abstract: Provided in embodiments of the present disclosure are a Channel State Information Reference Signal (CSI-RS) transmission method and apparatus. The method includes: configuration information is transmitted to a terminal, the configuration information including the number of Resource Blocks (RB) in an A-type RB group, and the A-type RB group comprises consecutive RBs for carrying all ports of CSI-RS; and the CSI-RS is transmitted to the terminal according to the configuration information. The present disclosure can solve the problem in the related art that system complexity is increased due to the unfixed number of antenna ports for the CSI-RS, and reduce the system complexity by transmitting the CSI-RS by means of the configuration information that includes the number of RBs included in the A-type RB group, and the A-type RB group comprises the consecutive RBs for carrying all the ports of the CSI-RS.
