Problems solved by technology

figure 1 A schematic diagram of pilot pollution is given, the terminal 202 and the terminal 203 are located in cell 0 and cell 1 respectively, and the SRS resources allocated to the terminal 202 and the terminal 203 are the same, causing the baseband processing unit 101 to receive the uplink SRS signal of the terminal 202 in this cell, At the same time, the uplink SRS signal of the terminal 203 in the neighboring cell is also received, so the uplink SRS signal of the terminal 202 received by the baseband processing unit 101 is interfered, so that the baseband processing unit subsequently uses the uplink SRS signal for signal processing accuracy greatly reduced, so that it is impossible to accurately locate the terminal in the cell

Abstract

The invention discloses a positioning method and device. The method comprises the steps of: determining an adjacent cell performing cooperative positioning with a first cell, wherein the SRS (Sounding Reference Signal) resource configured for the adjacent cell and the SRS resource configured for the first cell belong to mutually orthogonal SRS resources; aiming at any terminal in the first cell, receiving wireless signal measurement values sent by a first group of access points, wherein the first group of access points are located in the first cell and can receive uplink signals of the terminal; acquiring wireless signal measurement values sent by the adjacent cell, wherein the wireless signal measurement values are generated by a second group of access points in the adjacent cell, and the second group of access points can receive uplink signals of the terminal; and generating a positioning result of the terminal for multi-cell joint positioning according to the wireless signal measurement values of the first group of access points and the second group of access points.

Description

technical field [0001] The present invention relates to the communication field, in particular to a positioning method and device. Background technique [0002] At present, the positioning technology of terminals in mobile communication networks has attracted more and more people's attention. The application of location-based services has flourished and penetrated into all aspects of social life, such as navigation services, location push and associated search, and big data behavior. In this era, various information services derived from location information will shine, which will further highlight the importance of positioning technology. [0003] Currently, in the coverage application of the cell merging system, since a cell is composed of a baseband processing unit and multiple remote radio units, the coverage of each cell is continuous. The SRS signal also receives uplink SRS signals from terminals in other cells. When terminals in different cells are allocated the same...
