8. A communications apparatus, comprising:
a processor, and a memory, wherein the memory is configured to store a computer program, and the processor is configured to execute the computer program stored in the memory, to cause the communications apparatus to perform following:
receiving first resource indication information, wherein the first resource indication information indicates a first time domain resource, the first time domain resource at least partially overlaps a second time domain resource, the second time domain resource is allocated for transmission of a first uplink signal, and the first resource indication information indicates that the second time domain resource is to be occupied at least part partially by a second uplink signal;
detecting first indication information, wherein the first indication information indicates a transmission attribute of the first time domain resource, and the first indication information comprises slot format information;
in response to the slot format information being detected successfully and the slot format information indicating that a transmission direction of the first time domain resource is a non-uplink transmission direction, prohibiting sending of at least a part of the first uplink signal on the second time domain resource; and
in response to the slot format information being detected successfully and the slot format information indicating that the transmission direction of the first time domain resource is an uplink transmission direction, sending the first uplink signal on the second time domain resource.
9. The communications apparatus according to claim 8 , wherein the first resource indication information is preemption indication (PI).
10. The communications apparatus according to claim 8 , wherein the first resource indication information is first uplink grant information.
11. The communications apparatus according to claim 8 , wherein
in response to failing to detect the slot format information, the computer program in the memory further causes the communications apparatus to send the first uplink signal on the second time domain resource.
12. The communications apparatus according to claim 8 , wherein
in response to failing to detect the slot format information, the computer program in the memory further causes the communications apparatus to prohibit sending of at least a part of the first uplink signal on the second time domain resource.
