Pilot allocation method for joint communication and positioning (JCAP) in millimeter-wave band

The present invention relates to the technical field of wireless communication and positioning based on a millimeter wave, and relates to a pilot frequency distribution method for joint communication and positioning based on a millimeter wave band. The method comprises: a base station establishing communication with a user, so that a transmitting end and a receiving end can obtain real-time channel state information by means of pilot frequency distribution. When the base station estimates the location of the user according to the channel state information, an optimal dynamic pilot frequency ratio under current conditions can also be designed according to a channel state, thereby realizing higher system throughput and positioning precision in the next round of transmission. The beneficial effects of the present invention are: by means of the present invention, both a positioning function and a communication function can be realized in a unified band, and an operation mode is optimized by means of constant iteration, thereby improving the real-time positioning precision and increasing the communication rate to meet system requirements; moreover, in the present invention, by means of the operation mode, which is iterated in real time, continuous high-precision tracking of the location of a user can be realized.
