A resource indication method, comprising: receiving, by a first terminal from a base station, a time-frequency resource allocation message, wherein the time-frequency resource allocation message allocates a second time-frequency resource for data transmission; receiving (S302, S303), by the first terminal from the base station, time-frequency resource indication information, wherein the time-frequency resource indication information indicates a first time-frequency resource that is preempted by the another terminal, and the first time-frequency resource overlaps the second time-frequency resource for the data transmission and comprises a preempted time domain unit and a preempted frequency domain unit; and performing, by the first terminal, the data transmission with the base station, by using a time-frequency resource that is in the second time-frequency resource and that does not overlap the first time-frequency resource; characterized by receiving, by the first terminal from the base station, information indicating division of time-frequency resources that can be preempted by another terminal, wherein the division of the time-frequency resources that can be preempted comprises at least one time domain unit and at least one frequency domain unit, wherein the first time-frequency resource is limited to a range by using the time-frequency resource division information; wherein the preempted time domain unit is comprised in the at least one time domain unit, the preempted frequency domain unit is comprised in the at least one frequency domain unit and the time-frequency resource indication information includes a quantity of bits which is based on the number of the at least one time domain unit and the number of the at least one frequency domain unit within the range. receiving, by a first terminal from a base station, a time-frequency resource allocation message, wherein the time-frequency resource allocation message allocates a second time-frequency resource for data transmission; receiving (S302, S303), by the first terminal from the base station, time-frequency resource indication information, wherein the time-frequency resource indication information indicates a first time-frequency resource that is preempted by the another terminal, and the first time-frequency resource overlaps the second time-frequency resource for the data transmission and comprises a preempted time domain unit and a preempted frequency domain unit; and performing, by the first terminal, the data transmission with the base station, by using a time-frequency resource that is in the second time-frequency resource and that does not overlap the first time-frequency resource; characterized by receiving, by the first terminal from the base station, information indicating division of time-frequency resources that can be preempted by another terminal, wherein the division of the time-frequency resources that can be preempted comprises at least one time domain unit and at least one frequency domain unit, wherein the first time-frequency resource is limited to a range by using the time-frequency resource division information; wherein the preempted time domain unit is comprised in the at least one time domain unit, the preempted frequency domain unit is comprised in the at least one frequency domain unit and the time-frequency resource indication information includes a quantity of bits which is based on the number of the at least one time domain unit and the number of the at least one frequency domain unit within the range.
