Background
In a Long Term Evolution (LTE) system, an Observed Time Difference Of Arrival (OTDOA) based on a Positioning Reference Signal (PRS) is a typical Positioning scheme. A User Equipment (UE) performs timing measurement on PRSs transmitted by a plurality of base stations to obtain a Reference Signal Time Difference (RSTD) measurement result from the UE to each base station. Combining the position of each base station transmitting antenna and the RSTD measurement value, the base station or the UE can obtain the UE position coordinate through a position estimation algorithm.
In the LTE system, PRS transmits with omni-directional beams, so the UE wirelessly considers the problem of receive Beam (Rx Beam) switching. In a New Radio (NR) system, due to the introduction of higher frequency band support and Beam management, each cell supports multiple beams with different directions, and reference signals may be transmitted by using beams with different directions, which results in that a UE needs to perform Beam scanning (Beam scanning) multiple times to acquire PRSs transmitted by different base stations.

Detailed Description
In the current implementation scheme, for the NR system, each cell supports multiple beams with different directions, and the reference signals may be transmitted by using the beams with different directions, which results in that the UE needs to perform multiple Beam scanning (Beam scanning) to acquire positioning reference signals transmitted by different base stations, thereby resulting in lower positioning accuracy of the UE.
According to the embodiment of the invention, the positioning reference signal is sent to the UE to be positioned through the first sending wave beam, and the auxiliary information is sent to the UE to be positioned, so that on one hand, the UE to be positioned can accurately receive the positioning reference signal sent by the serving cell based on the auxiliary information, and accurate timing information is obtained; on the other hand, the UE to be positioned can select the second receiving beam to receive the positioning reference signals sent by other cells based on the auxiliary information, so that the times of switching the receiving beams by the UE are reduced, and the positioning accuracy is improved.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Referring to fig. 1, an embodiment of the present invention provides a method for transmitting a positioning reference signal, where the method may include the following steps;
step S101, obtaining an optimal beam corresponding to UE to be positioned, and using the optimal beam as a first sending beam.
For the NR system, since each cell may support a plurality of beams with different directions, in order to improve the positioning performance, an optimal beam corresponding to a UE to be positioned may be selected as a first transmission beam, and then a positioning reference signal may be transmitted via the first transmission beam.
In a specific implementation, the optimal beam may be an optimal beam reported by the UE to be positioned based on a beam training result. For the NR system, one Cell (Cell) may be composed of a plurality of beams (Beam). When a cell includes multiple beams, each beam broadcasts its corresponding Synchronization Signal BLOCK (SS BLOCK), and the UE performs beam training by receiving the Synchronization Signal BLOCK and reports the beam training result to the base station.
For example, the UE may select a beam with the highest received signal-to-noise ratio as an optimal beam according to the synchronization signal block, or select a beam with the strongest received signal as an optimal beam, and report the optimal beam to the base station through a beam training result.
In an embodiment of the present invention, the obtaining an optimal beam corresponding to a UE to be located includes: receiving a beam training result reported by the UE to be positioned; and acquiring the optimal beam corresponding to the UE to be positioned based on the beam training result.
Step S102, sending auxiliary information to the UE to be positioned, wherein the auxiliary information comprises: the serving cell transmits a first transmission beam of positioning reference signals.
In a specific implementation, in order to facilitate the UE to be positioned to obtain accurate timing information, a first transmission beam for the serving cell to transmit the positioning reference signal may be transmitted to the UE to be positioned.
In a specific implementation, in order to facilitate the UE to be located to calculate the position coordinate, auxiliary information corresponding to each base station (i.e., each base station that sends the positioning reference signal) may be sent to the UE to be located, where the auxiliary information includes relevant configuration information of the positioning reference signal of each base station, so that a first sending beam, i.e., Spatial quasi-co-Location (Spatial QCL) information, of the positioning reference signal sent by the serving cell may be sent to the UE to be located by using the auxiliary information corresponding to the serving cell.
Step S103, the positioning reference signal is sent to the UE to be positioned based on the first sending beam.
For the NR system, because each cell may support a plurality of beams with different directions, and each base station that transmits a positioning reference signal covers the entire cell in a Beam scanning (Beam Sweep) manner, resulting in poor positioning performance of the UE, the embodiment of the present invention may further transmit the location information of the serving cell to a neighboring cell corresponding to the UE to be positioned, so that the neighboring cell selects a reasonable Beam to transmit the positioning reference signal based on the location information.
In an embodiment of the present invention, the method for sending the positioning reference signal may further include: and sending position information to a neighboring cell (namely, a neighboring cell) corresponding to the UE to be positioned, so that the neighboring cell selects a second sending beam to send the positioning reference signal based on the position information.
By sending the position information of the serving cell to the adjacent cell corresponding to the UE to be positioned, the adjacent cell can select a proper sending beam to send the positioning reference signal based on the position information of the serving cell, and the positioning performance is improved.
By applying the scheme, the positioning reference signal is sent to the UE to be positioned through the first sending beam, and the auxiliary information is sent to the UE to be positioned, so that on one hand, the UE to be positioned can accurately receive the positioning reference signal sent by the serving cell based on the auxiliary information, and accurate timing information is obtained; on the other hand, the UE to be positioned can select the second receiving beam to receive the positioning reference signals sent by other cells based on the auxiliary information, so that the times of switching the receiving beams by the UE are reduced, and the positioning accuracy is improved.
In order to make those skilled in the art better understand and implement the present invention, the embodiment of the present invention further provides a method for receiving a positioning reference signal, as shown in fig. 2.

Step S202, a first receiving beam is determined based on the first transmitting beam.
Step S203, receiving the positioning reference signal sent by the serving cell based on the first receiving beam.
In a specific implementation, a first receiving beam may be first determined based on the first transmitting beam, and then the positioning reference signal transmitted by the serving cell via the first transmitting beam may be received through the first receiving beam to obtain precise timing (timing) information.
Step S204, determining a second receiving beam based on the first receiving beam, where the second receiving beam is used for receiving the positioning reference signal sent by a neighboring cell.
In a specific implementation, for positioning reference signals of neighboring cells, a Beam Sweep (Beam Sweep) manner may be employed to receive with the second receive Beam.
In order to improve the positioning performance, a second receiving beam for receiving the positioning reference signals transmitted by the neighboring cells may be determined according to a principle of dispersion of respective angular positions based on the first receiving beam. For example, the first receive beam is at angle a and another direction different from angle a, e.g., direction B, is selected as the direction of the second receive beam.
In a specific implementation, the number of the second receiving beams may be one or multiple.
When the second receiving beam is plural, directions of plural different second receiving beams may be determined according to a principle of dispersion of respective angular positions.
