Positioning information transmitting method and device

The embodiment of the invention provides a positioning information transmitting method and a positioning information transmitting device. The positioning information transmitting method comprises the following steps of: determining a positioning subframe which transmits a positioning reference signal; and transmitting the positioning reference signal according to the positioning subframe. Through the method, the positioning reference signal is transmitted according to the positioning subframe, the normal transmission of SCH and/or BCH can be ensured, and the transmission of the positioning subframe has no influence on the detection performance of the SCH and/or BCH.
