Sequential control method and device for radio frequency of wireless communication terminal

Abstract

The invention discloses a sequential control method and device for radio frequency of a wireless communication terminal. A frame timer and an event sequence timer in the radio frequency sequential timing control structure are separated and the startup of the event sequence timer is controlled by the frame timer. After a sequencer is started, the trigger time of a radio frequency interface event and the value of the event sequence timer are compared. The corresponding radio frequency interface event is triggered when the trigger time is reached. In this way, the adjustment operation on the frame timer does not affect the execution of the already configured event, thus avoiding a false command action. Moreover, an instruction pre-fetch module is added. When the instruction of the radio frequency interface event read from the instruction fetch module is not triggered successively following the last instruction, the instruction is written into the instruction pre-fetch module and then the instruction of next radio frequency interface event is read by the instruction fetch module, thereby the decoding and execution module can process the next instruction after processing the instruction of the last radio frequency interface event, and makes full use of the clock cycle consumed by the instruction fetch.

Description

technical field [0001] The invention relates to a radio frequency sequence control technology of a wireless communication terminal. Background technique [0002] In a wireless communication system, in order to synchronize the data sent and received by the terminal with the network, there must be a timing device in the terminal to time the radio frequency control events. A common timing method is to set up a frame timer in the terminal, and use the frame timer to time the configured radio frequency control events. [0003] For example, in the Time Division Synchronous Code Division Multiple Access (TD-SCDMA) system, in order to receive the information of a certain time slot, the terminal must have two instructions in the event sequencer, one is to start Receive radio frequency data command, another is to end receiving radio frequency data command. These commands all contain a trigger time parameter, which will be compared with the value of the frame timer. When the value o...
