A method for configuring transmission resource cancelation indication information, applied to a terminal device, the method comprising: receiving configuration information from a network device, the configuration information being used for configuring transmission resource cancelation indication information and configuring a first reference time region related to the transmission resource cancelation indication information, wherein a reference time region indicates time resources where transmission needs to be cancelled; and parsing the transmission resource cancelation indication information based on the configuration information to obtain a resource position where transmission is canceled, wherein a time starting point of the first reference time region is determined based on a last symbol of a Control Resource Set, CORESET, where the transmission resource cancelation indication information is located and a starting point offset of the transmission resource cancelation indication information, and the starting point offset of the transmission resource cancelation indication information is a time interval between a transmission ending time of the transmission resource cancelation indication information and the time starting point of the first reference time region related to the transmission resource cancelation indication information, characterized in that, under a multi-carrier condition with simultaneous transmissions on multiple carries and with a transmission resource cancellation indication configured for each carrier, a reference time region is determined for each of the multiple carriers, and a time length in symbols for each of the reference time regions is determined based on a subcarrier spacing, SCS, of the corresponding carrier and based on a time length corresponding to the first reference time region, wherein the first reference time region corresponds to a first SCS, and the first SCS is an SCS of a carrier carrying the transmission resource cancelation indication information. receiving configuration information from a network device, the configuration information being used for configuring transmission resource cancelation indication information and configuring a first reference time region related to the transmission resource cancelation indication information, wherein a reference time region indicates time resources where transmission needs to be cancelled; and parsing the transmission resource cancelation indication information based on the configuration information to obtain a resource position where transmission is canceled, wherein a time starting point of the first reference time region is determined based on a last symbol of a Control Resource Set, CORESET, where the transmission resource cancelation indication information is located and a starting point offset of the transmission resource cancelation indication information, and the starting point offset of the transmission resource cancelation indication information is a time interval between a transmission ending time of the transmission resource cancelation indication information and the time starting point of the first reference time region related to the transmission resource cancelation indication information, characterized in that, under a multi-carrier condition with simultaneous transmissions on multiple carries and with a transmission resource cancellation indication configured for each carrier, a reference time region is determined for each of the multiple carriers, and a time length in symbols for each of the reference time regions is determined based on a subcarrier spacing, SCS, of the corresponding carrier and based on a time length corresponding to the first reference time region, wherein the first reference time region corresponds to a first SCS, and the first SCS is an SCS of a carrier carrying the transmission resource cancelation indication information.
