Wherein, downlink Control Information (DCI) is transmitted through a Physical Uplink Shared Channel (PUSCH) of a scheduling current time slot, and response is made to the transmission of Uplink data in time by receiving the DCI.
In this embodiment, the terminal device receives DCI information through an air interface receiving manner, so as to decode the DCI information subsequently, thereby determining a timing condition of uplink data to be sent.

In a possible embodiment, a first operation core of the multi-core processor first performs hardware decoding on the DCI, so as to obtain hardware decoding data, and then performs software decoding and software scheduling on a payload in the hardware decoding data, so as to obtain a decoding result, where the decoding result at least includes parameter data, and the parameter data at least includes a fixed address.
In a possible embodiment, after the first operation core of the multicore processor performs software scheduling on the DCI, the scheduling result is determined, and after it is determined that the current software scheduling is the emergency scheduling with a DCI format of 0, it indicates that the scheduling corresponding to the current DCI is the emergency scheduling and needs to be executed immediately, so that the physical layer transmits the decoding result to a Medium Access Control (MAC), so that the MAC layer responds according to the decoding result to complete the uplink data group packing process.
And S203, the MAC layer of the terminal equipment packages the uplink data to be sent through a second operation core of the multi-core processor according to the decoding result to obtain packaged data, and stores the packaged data into a memory pool according to a fixed address.
