detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

The embodiment of the present invention discloses a terminal positioning method and related equipment, which can effectively improve the positioning accuracy of the terminal and save the cost of the positioning algorithm of the mobile communication system. Each will be described in detail below.

In order to better understand the embodiment of the present invention, a terminal positioning network architecture disclosed in the embodiment of the present invention is firstly described below. Please refer to FIG. 1 . FIG. 1 is a schematic diagram of a network architecture for terminal positioning disclosed by an embodiment of the present invention. The network architecture shown in FIG. 1 may include base stations and terminals, wherein one base station may communicate with one or more terminals, and one base station may cover one or more cells. In the network architecture shown in Figure 1, terminals can include mobile phones, handheld computers, tablet computers, personal digital assistants (Personal Digital Assistant, PDA), mobile Internet devices (Mobile Internet Device, MID), vehicle-mounted terminals or wearable devices (such as smart watches, smart bracelets, etc.) and other various terminals are not limited in the embodiments of the present invention.

In the network architecture shown in Figure 1, a single base station can be used to locate terminals in real time. In mobile communication systems, such as GSM (Global System for Mobile communication, Global System for Mobile Communications), UMTS (Universal Mobile Telecommunications System, Universal Mobile Communication system), LTE (Long Term Evolution, long-term evolution) system, etc., the base station can use the PMI information fed back by the terminal to select the best codebook for weighted transmission of the service channel, and the information after the codebook weighting forms different directions on the antenna. The base station determines the azimuth angle of the terminal by selecting the best codebook combined with the installation direction angle and downtilt angle of the cell antenna, and then combines the transmission delay when the base station communicates with the terminal and the longitude and latitude information of the base station to realize the positioning of the terminal . Alternatively, the base station can receive multi-antennas based on the uplink. After calibrating the phase, the multi-channel signals can be assigned different antenna weights to obtain antenna patterns pointing to different azimuths. The signal is comprehensively analyzed to obtain the terminal orientation, and then combined with the transmission delay when the base station communicates with the terminal and the longitude and latitude information of the base station to realize the positioning of the terminal. Furthermore, the base station can use the uplink COMP information to uplink the COMP receiving level information in the serving cell of the terminal and the co-sited adjacent cell (that is, the adjacent cell that shares the base station with the serving cell), and the information such as antenna angle and antenna pattern can be used. The location information of the user is determined, and the positioning of the terminal is realized by combining the transmission delay when the base station communicates with the terminal and the latitude and longitude information of the base station. As for the existing terminal positioning technology, most of them rely on the surrounding base stations to locate the terminal, so the dependence on the neighboring base stations is strong, and the calculation process is complicated, and the positioning accuracy is poor. By implementing the network architecture shown in Figure 1, based on a single base station using multi-antenna technology to realize the positioning of the terminal, the terminal is located by considering the azimuth angle of the cell, the transmission time information between the base station and the terminal, and the latitude and longitude of the base station. Positioning does not need to rely on the information of surrounding neighboring cell base stations, which can effectively improve the positioning accuracy of the terminal, and save the cost of the positioning algorithm of the mobile communication system.

Based on the network architecture shown in FIG. 1 , the embodiment of the present invention discloses a terminal positioning method. Please refer to FIG. 2 . FIG. 2 is a schematic flowchart of a terminal positioning method disclosed in an embodiment of the present invention. As shown in Figure 2, the terminal positioning method may include the following steps:

201. The base station receives the precoding matrix indication PMI information sent by the terminal.

In the embodiment of the present invention, under the LTE system, the terminal can obtain the precoding matrix indication PMI information by measuring the pilot signal delivered by the base station. The terminal may automatically trigger to send the PMI information to the base station, or may receive a trigger instruction sent by the base station to trigger the terminal to send the PMI information to the base station. Wherein, the precoding matrix indication PMI can be used to make the terminal tell the base station what kind of precoding matrix to use to precode the PDSCH (Physical Downlink Shared Channel, Physical Downlink Shared Channel) of the terminal.

As an optional implementation manner, the specific implementation manner in which the base station receives the precoding matrix indication PMI information sent by the terminal in step 201 may include the following steps:

21) The base station receives the precoding matrix indication PMI information sent by the terminal and obtained by measuring the cell reference signal CRS.

In this embodiment, the cell reference information CRS is also called common reference information, which is equivalent to a cell-specific pilot, that is, a common pilot, which can be used for channel estimation and related demodulation of the codebook-based beamforming technology. The terminal obtains the PMI information by measuring the CRS information of the base station, and feeds it back to the base station.

202. The base station acquires an optimal codebook according to the PMI information.

In the embodiment of the present invention, based on the PMI information fed back by the terminal, the base station can select an optimal codebook from multiple allocated codebooks. Under the LTE system, according to the 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project), there are currently 16 codebooks for 4 antennas, and the positioning accuracy can be further improved after the number of codebooks based on the protocol evolution is increased.

In the embodiment of the present invention, the method described in FIG. 2 may further include the following steps:

22) The base station uses the optimal codebook to perform weighting processing on the downlink signal to be sent, and sends the weighted downlink signal to the terminal through the antenna.

In the embodiment of the present invention, the base station can also perform service communication with the terminal while positioning the terminal. The base station may shape the weighted downlink signal and send it out through the antenna, so that the terminal receives the shaped downlink signal.

In the embodiment of the present invention, under the mobile communication system, the base station selects the best codebook among multiple codebooks according to the PMI information fed back by the terminal to weight the downlink signals to be sent, and the weighted signals are respectively shaped and sent on the horizontal plane, At the same time, the downtilt angle is opened by the antenna on the vertical plane, and corresponding beams are also formed on the horizontal plane for service transmission.

203. The base station determines the azimuth angle of the terminal relative to the serving cell according to the optimal codebook and the phase information of the base station.

In the embodiment of the present invention, the phase information of the base station may be the phase information when the base station and the terminal perform communication services. The phase information of the base station can be pre-stored in the memory of the base station; it can also be measured and calculated by the base station according to the coordinated multi-point transmission COMP mode.
