Abstract

This application provides an information transmission method and an apparatus. The method includes: determining, by a terminal device, a target time domain interval, where a time domain resource in the target time domain interval includes at least one candidate time domain resource used to carry first resource indication information, the first resource indication information is used to indicate a first time domain resource, the first time domain resource at least partially overlaps a second time domain resource, and the second time domain resource is used to carry a first uplink signal; receiving, by the terminal device, the first resource indication information on a first candidate time domain resource in the target time domain interval; and prohibiting, by the terminal device based on the first resource indication information, sending of at least a part of the first uplink signal.

Claims20

Dependent claims

A method comprising:

receiving, by a terminal device, 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 partially by a second uplink signal;
detecting, by the terminal device, 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, by the terminal device, 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, by the terminal device, the first uplink signal on the second time domain resource.

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.
