Embodiment Construction

[0024] In order to reduce the development cost of the non-universal frequency band terminal, in the embodiment of the present invention, the architecture of the general frequency band terminal is mutated and innovated, and a front-end frequency conversion unit is added on the basis of the general architecture to convert the general frequency band to the non-universal frequency band. Realize the maximum reuse of existing terminal chips and protocol stacks, thereby reducing the development cost and power consumption of non-common frequency band terminals.

[0025] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. In the following embodiments, for ease of description, the diversified non-common frequency band is called frequency band a, and the common frequency band is called frequency band b.

[0026] Based on the general frequency band terminal architecture, the present invention adds a front-end freq...

Abstract

The invention relates to the field of communication, and discloses a non-universal frequency band terminal and an application method thereof, which are used for decreasing the development cost of the non-universal frequency band terminal. In the method, a universal frequency band terminal is restructured, namely an additional front-end frequency conversion module capable of performing spectrum shifting is arranged in the universal terminal, and the restructured universal frequency band terminal can work on the non-universal frequency band under the assistance of the front-end frequency conversion module. In such a way, the restructured universal frequency band terminal can be viewed as a novel non-universal frequency band terminal. Compared with the conventional universal frequency band terminal, the non-universal frequency band terminal designed in the embodiment of the invention has the advantages of flexibility and high development speed; the development cost of the non-universal frequency band terminal is effectively decreased; and terminal architectures with proper cost and proper power consumption are provided for low-capacity networks or private network markets, and proper terminals can be possible and convenient to promote rapidly in special frequency bands.

Description

technical field [0001] The present invention relates to the communication field, in particular to a terminal applied in a non-universal frequency band and an application method thereof. Background technique [0002] At present, 3GPP has planned several frequency bands for TDD (Time Division Duplex) system and FDD (Frequency Division Duplex) system. For example, the frequency bands that can be used by the TDD system are 11 frequency bands from BAND33 to BAND43, and the frequency bands that can be used by the FDD system are BAND1~BAND21, and BAND24 have a total of 22 frequency bands. However, for industrial applications, such as government, coal mines, railways, etc., the frequency bands used are generally not within the range of frequency bands planned by 3GPP, but belong to non-common diversity frequency bands. [0003] In practical application, it is generally difficult for chip manufacturers to easily set foot in the non-universal frequency band market due to cost and ben...
