Multi-mode radio frequency timing control device, control method and multi-mode baseband chip

Abstract

The invention discloses a multi-mode radio frequency timing control device, comprising: a multi-mode input control module, which receives instructions from a multi-mode baseband chip CPU, and obtains timing control information from the received instructions; saves effective timing control information to Control information storage module; the control information storage module stores effective timing control information; the multi-mode output control module reads the timing control information with the earliest timing time from the control information storage module; parses the timing control data, and parses the timing control data when the timing time arrives The final timing control data is sent to the control interface unit; the control interface module outputs the parsed timing control data to the radio frequency system corresponding to the communication mode of the timing control data. The technical scheme of the present invention uses a set of radio frequency control circuits to realize multi-mode radio frequency timing control, effectively reducing the power consumption and cost of multi-mode baseband chips. The invention also discloses a control method and a multimode baseband chip adapted to the device.

Description

technical field [0001] The invention relates to a baseband radio frequency timing control technology in a mobile communication system, in particular to a multimode radio frequency timing control device and method and a multimode baseband chip. Background technique [0002] In the mobile communication system, in order to ensure the normal communication between the mobile terminal and the network, the baseband chip must be able to implement precise timing control on the working state of the radio frequency circuit. That is, the baseband chip writes the timing control data for controlling the baseband radio frequency path and peripheral radio frequency devices and the timing time corresponding to each timing control data into the radio frequency control device in advance, and executes the control data corresponding to the timing time point when the timing time point arrives, Control the radio frequency system to perform corresponding operations. [0003] In a multi-mode mobile...
