s220, if the first time domain resource and the second time domain resource are overlapped, signal transmission is processed according to a preset rule.
If the first time domain resource and the second time domain resource overlap, the terminal cannot transmit PUSCH and receive PDSCH at the same time, so that the terminal can only select one for processing the PUSCH transmission processing and the PDSCH transmission processing, and therefore a certain rule needs to be set for processing the conflict, so as to improve the reliability of data transmission.
Optionally, the processing the signal transmission according to the preset rule in S220 includes:

Another example is: and processing scheduling corresponding to information with later sending time in the first information and the second information. If the network equipment firstly transmits the first information and then transmits the second information, processing scheduling corresponding to the second information, namely, processing the PDSCH by the terminal; if the network equipment firstly sends the second information and then sends the second information to the first information, scheduling corresponding to the first information is processed, namely the terminal processes the PUSCH.

Optionally, the processing the signal transmission according to the preset rule in S220 includes:
s222, processing at least one of the PUSCH and the PDSCH according to the priority of the service scheduled by the first information and the second information.
For example: if the priority of the service scheduled by the first information is higher than that of the service scheduled by the second information, processing the scheduling corresponding to the first information, namely, processing the PUSCH by the terminal; and if the priority of the service scheduled by the second information is higher than that of the service scheduled by the first information, processing the scheduling corresponding to the first information, namely, processing the PDSCH by the terminal.

Such as: in fig. 3, if the PUSCH transmission time is earlier than the PDSCH transmission time in the first schedule 310, the schedule corresponding to the first information is processed, i.e., the PUSCH is processed; and if the PDSCH transmission time is earlier than the PUSCH transmission time in the third schedule 330, processing the schedule corresponding to the second information, that is, processing the PDSCH.
If the PUSCH transmission time is the same as the PDSCH transmission time in the second schedule 320, the corresponding schedule may be determined according to other rules as described above, for example, the schedule corresponding to the information having the earlier transmission time in the first information and the second information, that is, the PDSCH may be processed.
The four preset rules for processing signal transmissions disclosed in the first embodiment of the present application may be used in combination, that is, when it is impossible to determine which schedule should be processed according to one of the rules, at least one other method may be adopted to assist in the determination. Such as: when the transmission and/or reception times of the first information and the second information are the same, which schedule should be processed may be determined according to one of the priorities of the first information and the second information scheduling service, or protocol conventions, or transmission times of PUSCH and PDSCH.
In an embodiment of the present application, when a first time domain resource indicated by first information for uplink scheduling overlaps with a second time domain resource indicated by second information for downlink scheduling, signal transmission is processed according to a preset rule. Therefore, the blank that no clear regulation exists in the prior art is made up, the system is more perfect, and the reliability of data transmission can be ensured. Specifically, if the terminal device processes the PUSCH, the network device may know that the PDSCH is not received, and may perform processing such as retransmission or rescheduling on the PDSCH as soon as possible, thereby ensuring data transmission reliability; if the PDSCH is processed, the network device can know that the PUSCH is not transmitted, and can perform processing such as retransmission scheduling or rescheduling on the PUSCH as soon as possible, thereby ensuring the reliability of data transmission.
