Problems solved by technology

However, as communication technology focuses on positioning enhancement for vertical industries, the typical scene is an indoor factory scene, such as automatic navigation vehicle (AGV) positioning, etc., and its positioning accuracy is required to be at the centimeter level; in addition, considering the moving speed of the AGV car Fast (greater than 30km / h), TA adjustment may occur during the positioning process, which will have a greater impact on its positioning accuracy

Embodiment Construction

[0093] In order to make the technical problems, technical solutions and advantages to be solved by the embodiments of the present invention clearer, the following detailed description will be given in conjunction with the accompanying drawings and specific embodiments.

[0094] For timing measurements that need to send uplink positioning reference signals, such as UL-RTOA (uplink reception time of arrival) and UE Rx-Tx time difference (terminal reception-transmission time difference), these timing measurements all involve the terminal's uplink transmission time. Therefore, if the terminal receives the TA adjustment amount and adjusts the uplink transmission time during the measurement period, it will affect the measurement accuracy, such as figure 1 As shown, the Tx timing is the sending time, the Rx timing is the receiving time, the PRS is the positioning reference signal, and the SRS is the sounding reference signal.

[0095] The positioning measurement is similar to the lay...

Abstract

The invention provides a positioning measurement reporting method and device and a positioning measurement configuration method and device, and belongs to the technical field of communication. The positioning measurement configuration method is applied to a network node, and the method comprises: sending a first measurement configuration message to a first device, the first measurement configuration message carrying first indication information, the first indication information being used for indicating the first device to enable subsection reporting. According to the technical scheme, the positioning precision of the terminal can be ensured.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a method and device for positioning measurement reporting and positioning measurement configuration. Background technique [0002] New Radio (NR) supports a variety of positioning technologies, including downlink positioning technology, that is, the base station (gNB) sends downlink positioning reference signals, and the terminal (User Equipment, UE) performs measurement; uplink positioning technology, that is, the terminal sends uplink positioning technology. Positioning reference signal, the technology that the base station performs measurement; the positioning technology that combines uplink and downlink, that is, the technology that the base station and the terminal exchange positioning reference signals and perform measurement. Among them, for the uplink positioning technology and the positioning technology combining the uplink and the downlink, the ter...
