Abstract

The invention discloses a positioning pilot priority indication method, which comprises the following steps of: defining the priority of a positioning reference signal and defining the priority of a downlink signal; comparing the priorities of the positioning reference signal and the downlink signal, and determining to abandon one signal when the positioning reference signal conflicts with the downlink signal according to a comparison result and a preset priority principle; wherein the positioning reference signal is a periodic downlink positioning pilot signal. The invention further comprisesa device applying the method. The method and the device solve the problem that the low delay requirement of timing service cannot be met, and are particularly suitable for the 3GPP NR radio technology.

Description

technical field [0001] The present application relates to the technical field of mobile communication, and in particular to a positioning pilot priority indication method and device. Background technique [0002] The application requirements of positioning put forward more and more stringent requirements for positioning delay and positioning accuracy. 3GPP NR (New Radio) radio technology can work in high and low frequency bands and support larger signal bandwidth. By adopting OTDOA (Observed Time Difference of Arrival , time difference of arrival positioning method) and UTDOA (Uplink Time Difference of Arrival, Uplink Time Difference of Arrival), Cell-ID or E-Cell-ID and other timing measurement positioning technologies can achieve new positioning performance boundaries, and at the same time, NR applications are large-scale Antenna arrays, utilizing the spatial and angular domains of the propagation channel combined with timing measurements, enable more accurate user positio...
