Embodiment

[0054] The present invention utilizes the D-band 4G received signal RSRP to convert the distance (path loss) between the receiving end of the device and the base station, and on this basis controls the total power of the uplink transmission of the analog channel to achieve the purpose of not interfering with the base station.

[0055] The total power of 5G base station PRU is 35dBm, and the total power of 4G base station PRU is 33dBm.

[0056] The total power converted from 4G receiving RSRP is: RSRP+30.8.

[0057] The path loss from the base station to the receiving end is: loss=33-(RSRP+30.8).

[0058] The uplink transmission power of each RB of the 5G terminal to the power of the base station:

[0059] P=Pout-35-loss=Port-35-[33-(RSRP+30.8)

[0060] P=Pout-68+30.8+RSRP

[0061] P=Pout-37.2+RSRP

[0062] 5G base station noise floor and 4G frequency band requirements are consistent: ≤-110dBm

[0063] The preset uplink open-loop power control value is ΔP, and ΔP is the powe...

Abstract

The invention discloses a method for calculating uplink transmission open-loop power control of a 5G repeater by utilizing 4G field intensity, which comprises the following steps of: converting a distance from a receiving end of equipment to a base station by utilizing a D-band 4G receiving signal RSRP, and controlling the uplink transmission total power of a 5G channel on the basis of the distance without interfering the base station. According to the invention, uplink power control is carried out on a 5G channel by using a 4G mature technology, which is easy to realize; under the condition that no 5G chip exists, the uplink transmitting power of the 5G channel is intelligently controlled through the relation between 4G and 5G, the equipment hardware cost is reduced, the surveying workload before engineering construction is reduced, after a base station is optimized in the later period, the equipment can automatically adapt to the current network condition, the later maintenance cost is reduced, and automatic adaptation in the later period of one-time construction of the repeater is achieved; and the equipment is installed at different positions and is located at different distances from a base station, and when the equipment works, the equipment is controlled at different uplink transmitting powers through software, so that the power consumption is reduced, and the electric energy is saved.

Description

technical field [0001] The invention belongs to the communication field, and in particular relates to a method for calculating the open-loop power control of uplink transmission of a 5G repeater by using 4G field strength. Background technique [0002] With the advent of the era of big data, the demand for mobile data continues to increase. At the same time, the increasing popularity of smart phones has led to more and more mobile devices connected to the Internet, and users have also put forward more service requirements, resulting in mobile The surge in data traffic. [0003] For 4G technology, it has been unable to handle such a huge data flow. Therefore, in order to solve this situation, the fifth-generation mobile communication technology—5G has appeared in people's field of vision. [0004] In the application of 5G network, there will also be problems of blind areas, weak areas, and insufficient coverage. The repeater is an extremely economical and effective device t...
