Problems solved by technology

[0016] Since the signals sent by the cells of these two systems are different, the RRU equipment cannot accurately and completely detect the output power when it works under the two systems of TD-SCDMA and TD-LTE at the same time.

Embodiment Construction

[0039] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0040] like figure 1 As shown, it is a schematic structural diagram of the RRU device output power detection circuit adopted in the dual-mode RRU device output power detection method of the present invention. After the output signal is sent out by the digital processing chip FPGA, it passes through a digital-to-analog converter (DAC), a local oscillator modulator, a digital board filter, a digital board transmitting amplifier, a power amplifier PA amplifier, and a power amplifier circulator. The coupling circuit transmits the signal to the coupling feedback link of the power amplifier, and then the signal passes through SWITCH2 to select the direct feedback link of the po...

Abstract

The invention discloses a method for detecting output power of dual-mode RRU (remote radio unit) equipment. The method comprises the following steps of according to the cell carrier wave and power conditions of the existing TD-SCDMA (time division-synchronization code division multiple access) and TD-LTE (time division-long term evolution), selecting a dual-mode training sequence in the output power detection mode, wherein the dual-mode training sequence is the same as the cell frequency feature; in the next preset cycle, according to the TD-LET time slot, sending the dual-mode training sequence in the coincided time period of TD-SCDMA guard period and TD-LTE guard period in the time axis, sampling data, calculating the accumulative sum, and repeating the step for multiple times; converting the accumulative sum obtained by multiple data sampling into the power value, and calculating the feedback average power; and according to the feedback average power, calculating the output power. The method has the advantage that when the RRU equipment simultaneously works in the TD-SCDMA mode and the TD-LTE mode, the output power can be accurately and completely detected.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and system for detecting the output power of a dual-mode RRU device. Background technique [0002] Remote radio unit (RRU) is a kind of remote equipment, which can detect whether the transmission channel hardware of the equipment is good or bad by detecting the RRU output power, and can provide management station query and In case of abnormality, report the low power alarm of the device. [0003] In the existing implementation scheme, the RRU device works respectively in the two systems of Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) and Time Division Long Term Evolution (TD-LTE) There are respective RRU output power detection implementation methods. [0004] The RRU output power detection method when the RRU device works in TD-SCDMA is by detecting the downlink pilot time slot (Downlink Pilot Time Slot, DW) signal of the cell. In terms of...
