Uplink control method, system and terminal

The embodiment of the invention relates to the field of communication technology, and discloses an uplink control method, a system and a terminal. The method comprises steps: a first digital signal processor (DSP) receives to-be-transmitted uplink data frames and uplink authorization information; the first DSP executes a data preparation task on the uplink data frames; the first DSP generates a control linked list and transmits the control linked list to a sharing memory; and a second DSP acquires the control linked list from the sharing memory and executes a data assignment task on the uplink data frames according to indication of the control linked list. When the embodiment of the invention is executed, complexity of link control is simplified, system stability is improved, the main frequency demands on the single DSP can be reduced, and the chip stability is improved.
