Embodiment Construction

[0028] The present invention will be further described below in conjunction with the embodiments and drawings, but the implementation of the present invention is not limited thereto.

[0029] see figure 2 As shown, it is a schematic flowchart of Embodiment 1 of the method for processing an uplink signal of a base station according to the present invention. Such as figure 2 As shown, the method for processing the base station uplink signal in this embodiment includes the following steps:

[0030] Step S201: Receive the uplink radio frequency signal sent by the user end; wherein, the uplink radio frequency signal sent by the user end may be received through a base station antenna, or the uplink radio frequency signal sent by the user end may be received through a receiving device.

[0031] Step S202: Down-convert the received uplink radio frequency signal to an analog intermediate frequency signal;

[0032] Step S203: Modulate the analog intermediate frequency signal formed...

Abstract

The present invention provides a method and device for processing an uplink signal of a base station. The method includes: receiving an uplink radio frequency signal sent by a user end; down-converting the received uplink radio frequency signal to an analog intermediate frequency signal; The signal is modulated into a digital signal, and the digital signal is restored to an analog intermediate frequency signal after delay adjustment; the restored analog intermediate frequency signal is converted into an uplink radio frequency signal; the restored uplink radio frequency signal is output to the base station receiver. It solves the problem that the multipath uplink search window restricts the base station to receive the mobile station signal and the problem of high uplink communication bit error rate caused by the uplink reception exceeding the range of the multipath receiving window. The remote radio equipment such as GRRU / CRRU / WRRU can be freely applied in various scenarios, and at the same time, the coverage of the base station can be precisely controlled.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a method and device for processing uplink signals of a base station. Background technique [0002] The mobile communication network can basically be divided into three parts: mobile station, radio access network and core network. Wherein, the radio access network includes a radio network controller and a base station. The base station signal radiates the signal through the antenna feeder system to cover the target area. However, the coverage mode of the base station inevitably has weak areas and blind areas of coverage, which is a common problem for mobile communication base stations with increasingly high service quality requirements. GRRU / CRRU / WRRU remote radio system (GRRU: GSM Digital Remote RFUnits; CRRU: CDMA Digital Remote RF Units; WRRU: WCDMA Digital Remote RFUnits) and other radio remote systems introduce base station signals and amplify them to cover t...
