Abstract

The invention provides a 5G NR uplink energy measurement method. The method comprises the following steps: receiving a downlink wireless signal transmitted by a 5G NR mobile base station and an uplink wireless signal transmitted by a 5G target terminal; analyzing the downlink wireless signal to obtain an NR downlink frame header position and uplink resource allocation information of a 5G target terminal; and on the basis of the NR downlink frame header position and the uplink resource allocation information, performing correlation calculation on the uplink wireless signal in the frequency domain window to obtain uplink energy of the 5G target terminal. Compared with a traditional field intensity meter positioning mode, the method has the advantages that the PUSCH configuration information of the target terminal is analyzed by using the downlink wireless signal transmitted by the 5G NR mobile base station, the uplink energy of the 5G target terminal is accurately calculated, and the 5G target terminal is accurately positioned according to the uplink energy.

Description

technical field

[0001] The present invention relates to the field of mobile communications, and more particularly, to a 5G NR uplink energy measurement method. Background technique

[0002] With the popularization and advancement of 5G NR terminals, it is urgent to accurately detect the NR terminal signals of 5G target terminals in 5G private network mobile communication and disaster search, so that the location of trapped persons can be accurately located, which is convenient for Rescue the trapped people in time.

[0003] The previous detection method was applied in 2G, 3G, and 4G scenarios. Due to the frame structure of 5G NR, the method of obtaining the specific identifier C_RNTI of the target terminal has changed, the generation method of the 5G uplink PUSCH DMRS sequence, and the frequency domain, The time domain mapping method is different from other standards, so the previous uplink energy detection methods of other standards cannot be applied in 5G scenarios.
