Problems solved by technology

[0010] If the conventional sub-mode calibration scheme is adopted, there will be a large cost of repeated calibration
For example, Band3 needs to be supported in GGE, WCDMA, and LTE-FDD. According to the traditional sub-mode calibration scheme, Band3 will be calibrated in GGE, WCDMA, and LTE-FDD modes, and there is a cost of repeated calibration time.

Embodiment Construction

[0024] In summary, the embodiment of the present invention proposes a radio frequency calibration method of a multi-mode multi-frequency scheme. This method does not change the framework of the existing sub-mode calibration method. By multiplexing the calibration results of the same frequency band between different modes, it eliminates the time consumption of repeated calibration of the same frequency band between different modes, and significantly reduces the multi-mode and multi-frequency The calibration time of the scheme. The embodiments of the present invention can be used in multi-mode multi-frequency terminals, and can also be used in other radio frequency solutions. The following describes the embodiments of the present invention by taking a mobile terminal as an example.

Abstract

The invention relates to a radio frequency calibration method of a multimode multiband scheme. The method comprises the steps of using a general test signal for radio frequency calibration in a first mode of multiple modes sharing a first frequency band, and obtaining a calibration table; and taking the calibration table as a shared calibration result of the first frequency band in the multiple modes, wherein the other modes of the multiple modes and the first mode use a code table of the same format, and the general test signal is also applicable to the multiple modes.

Description

Technical field [0001] The invention relates to the field of mobile communication, and more specifically, to a radio frequency calibration method of a multi-mode and multi-frequency scheme. Background technique [0002] At present, cellular mobile communication technology is undergoing rapid changes. The second generation (2G) mobile communication technology is still in large-scale use, the third generation (3G) mobile communication technology is popularizing, and the fourth generation (4G) mobile communication technology has also begun. Commercial. In each generation of mobile communication technologies, there are different modes. For example, 2G has GGE (GSM / GPRS / EDGE) and CDMA, 3G has WCDMA, TD-SCDMA and CDMA2000, and 4G has TD-LTE and LTE-FDD. The coexistence of several generations of mobile communication technologies requires mobile terminals to support multiple modes of communication technologies. [0003] With the rapid development of full-mode solutions, the modes that mo...
