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 embodiments of the present invention propose a radio frequency calibration method for a multi-mode and multi-frequency solution. On the basis of not changing the framework of the existing sub-mode calibration method, this method eliminates the time consumption of repeated calibration of the same frequency band between different modes by multiplexing the calibration results of the same frequency band between different modes, and significantly reduces the multi-mode and multi-frequency Calibration time for the scheme. The embodiments of the present invention can be used for multi-mode multi-frequency terminals, and can also be used for other radio frequency schemes. The following describes 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 multi-mode and multi-frequency scheme, comprising the following steps: among multiple modes sharing a first frequency band, select a common test signal to perform radio frequency calibration in the first mode, and obtain a calibration table; The calibration table is used as the common calibration result of the first frequency band in the multiple modes; wherein other modes in the multiple modes use code tables in the same format as the first mode, and the general test signal is applicable to the Various modes.

Description

technical field [0001] The invention relates to the field of mobile communication, and more specifically, relates 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 becoming popular, and the fourth generation (4G) mobile communication technology has also begun. commercial. There are different modes in each generation of mobile communication technology, 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 makes mobile terminals need to support multiple modes of communication technologies. [0003] With the rapid development of the full-mode soluti...
