Embodiment 1

[0073] refer to figure 1 , which shows a flow chart of a method for radio frequency testing of a multi-bandwidth cell in this embodiment, and this embodiment may specifically include the following steps:

[0074] S101, for cells with different bandwidths, uniformly use the sampling rate of the maximum bandwidth in the multi-bandwidth cell to collect signals transmitted by the terminal;

[0075] In the traditional method, different sampling rates are used when testing cells with different bandwidths. For example, a sampling rate of 15.36 MHz is used for a system bandwidth of 10 MHz, and a sampling rate of 7.68 MHz is used for a system bandwidth of 5 MHz. However, this embodiment overcomes the technical bias and does not use the traditional method to reduce the sampling rate to meet the measurement requirements of different bandwidths, but uniformly adopts the sampling rate of the maximum bandwidth in the multi-bandwidth cell, which avoids the use of different bandwidths in the ...

Embodiment 2

[0085] It is known that radio frequency tests include any one of spectrum measurement, power measurement and signal quality measurement. When the radio frequency test is spectrum measurement, refer to figure 2 , is a flow chart of a method for spectrum measurement in a multi-bandwidth cell in this embodiment. The spectrum measurement in which the maximum bandwidth in a multi-cell is 20MHz and the subcarrier spacing is 15KHz as an example for an LTE terminal will be described below. This embodiment can specifically Include the following steps:

[0086] S201, for cells with different bandwidths, uniformly use the sampling rate of the maximum bandwidth in the multi-bandwidth cell to collect signals transmitted by the terminal;

[0087] For this embodiment, a sampling rate of 30.72 MHz with a maximum bandwidth of 20 MHz in a multi-bandwidth cell is uniformly used to collect signals transmitted by terminals.

[0088] The sampling rate of the maximum bandwidth in the multi-bandwid...

Embodiment 3

[0102] When the RF test is a power measurement or a signal measurement, refer to image 3 , is a flow chart of a method for measuring power or signal in a multi-bandwidth cell in this embodiment. The following uses an LTE terminal, where the maximum bandwidth in a multi-cell is 20MHz, and the frequency spectrum measurement with a subcarrier spacing of 15KHz is taken as an example. An embodiment may specifically include the following steps:

[0103] S301, for cells with different bandwidths, uniformly use the sampling rate of the maximum bandwidth in the multi-bandwidth cell to collect signals transmitted by the terminal;

[0104] Similar to Embodiment 2, this embodiment still uniformly uses a sampling rate of 30.72 MHz with a maximum bandwidth of 20 MHz in a multi-bandwidth cell to collect signals transmitted by terminals.

[0105] In this embodiment, the sampling rate of the maximum bandwidth is 30.72 MHz, and the sampling rate is obtained by multiplying the subcarrier inter...

Abstract

The invention provides a multi-bandwidth neighborhood radio frequency testing method, device and system and aims at solving the problem of how to reduce multi-bandwidth neighborhood radio frequency testing complexity. The multi-bandwidth neighborhood radio frequency testing method includes that for neighborhood with different bandwidths, signals transmitted by a sampling rate collection terminal in the multi-bandwidth neighborhoods and having the largest bandwidth are uniformly used; for the neighborhood with different bandwidths, the collected signals are subjected to fast Fourier transformation (FFT) by aid of FFT points in the multi-bandwidth neighborhoods and having the largest bandwidth to obtain frequency domain data; and the frequency domain data are adopted to continue to perform terminal radio frequency testing. The multi-bandwidth neighborhood radio frequency testing method, device and system can greatly reduce achievement complexity, save testing cost, meet requirements of wide frequency spectrum measurement, and have the advantages of high accuracy, fast testing, operating easiness and the like.

Description

technical field [0001] The present application relates to the field of communication technology, in particular to a method, device and system for radio frequency testing of multi-bandwidth cells. Background technique [0002] With the vigorous development of mobile communication, mobile Internet and intelligent terminals, more and more mobile terminals are produced. In order to ensure the security and interoperability of the communication network, all terminal equipment must pass the conformance test before being launched on the market. The so-called conformance test is to verify the consistency of the device implementation with the corresponding protocol standard, and to verify whether the device can meet the unified requirements of the protocol, so as to perform the same action under the same external conditions and output the same result. The terminal consistency test can ensure that terminals produced by different manufacturers perform consistently in the network and ca...
