The method includes: a terminal device receiving first information sent by a network device, where the first information indicates a second timer; in response to, at least in part, a measurement result of downlink reference signal receiving power (RSRP) being greater than a pre-configured RSRP threshold, the terminal device sending a first request to the network device, wherein the first request comprises a request for a SDT transmission resource; and the terminal device receiving second information sent by the network device, wherein the second information indicates the SDT transmission resource. ## Claims ### Claim 1 An apparatus, comprising: at least one processor; and one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor to cause the apparatus to perform operations comprising: sending first information to a terminal device, wherein the first information indicates a first timer and a second timer, and the second timer has a second duration of performing small data transmission (SDT), wherein the first timer has a first duration, wherein the first duration is shorter than the second duration, wherein the first duration is related to a timing advance (TA) timer; and receiving SDT based on configured grant (CG) resource, and wherein the SDT is sent by the terminal device in response to, at least in part, a measurement result of downlink reference signal receiving power (RSRP) being greater than a pre-configured RSRP threshold. ### Claim 2 (depends on 1) The apparatus according to claim 1, wherein the first duration is associated with a first transmission resource. ### Claim 3 (depends on 2) The apparatus according to claim 2, wherein the first transmission resource is a dedicated resource of the terminal device. ### Claim 4 (depends on 1) The apparatus according to claim 1, the operations further comprising: sending second information that comprises one or more of the following information: a size of allocatable resources, scheduled SDT resources, subsequent SDT resources, or SDT retransmission resources, or a size of transmission resources requested by other terminal devices in resource pool. ### Claim 5 (depends on 1) The apparatus according to claim 1, wherein the first information is carried in CG resource configuration information. ### Claim 6 One or more non-transitory computer-readable media storing computer instructions, that when executed by one or more processors, cause a computing device to perform operations comprising: receiving first information sent by a network device, wherein the first information indicates a first timer and a second timer, and the second timer has a second duration of performing small data transmission (SDT), wherein the first timer has a first duration, wherein the first duration is shorter than the second duration, wherein the first duration is related to a timing advance (TA) timer; and in response to, at least in part, a measurement result of downlink reference signal receiving power (RSRP) being greater than a pre-configured RSRP threshold, sending SDT based on configured grant (CG) resource. ### Claim 7 (depends on 6) The one or more non-transitory computer-readable media according to claim 6, wherein the first duration is associated with a first transmission resource. ### Claim 8 (depends on 7) The one or more non-transitory computer-readable media according to claim 7, wherein the first transmission resource is a dedicated resource of the computing device. ### Claim 9 (depends on 6) The one or more non-transitory computer-readable media according to claim 6, the operations further comprising: receiving second information that comprises one or more of the following information: a size of allocatable resources in the network device, scheduled SDT resources, subsequent SDT resources, or SDT retransmission resources, or a size of transmission resources requested by other terminal devices in resource pool. ### Claim 10 (depends on 6) The one or more non-transitory computer-readable media according to claim 6, wherein the first information is carried in CG resource configuration information. ### Claim 11 One or more non-transitory computer-readable media storing computer instructions, that when executed by one or more processors, cause a computing device to perform operations comprising: sending first information to a terminal device, wherein the first information indicates a first timer and a second timer, and the second timer has a second duration of performing small data transmission (SDT), wherein the first timer has a first duration, wherein the first duration is shorter than the second duration, wherein the first duration is related to a timing advance (TA) timer; and receiving SDT based on configured grant (CG) resource, and wherein the SDT is sent by the terminal device in response to, at least in part, a measurement result of downlink reference signal receiving power (RSRP) being greater than a pre-configured RSRP threshold. ### Claim 12 (depends on 11) The one or more non-transitory computer-readable media according to claim 11, wherein the first duration is associated with a first transmission resource. ### Claim 13 (depends on 12) The one or more non-transitory computer-readable media according to claim 12, wherein the first transmission resource is a dedicated resource of the terminal device. ### Claim 14 (depends on 11) The one or more non-transitory computer-readable media according to claim 11, the operations further comprising: sending second information that comprises one or more of the following information: a size of allocatable resources, scheduled SDT resources, subsequent SDT resources, or SDT retransmission resources, or a size of transmission resources requested by other terminal devices in resource pool. ### Claim 15 (depends on 11) The one or more non-transitory computer-readable media according to claim 11, wherein the first information is carried in CG resource configuration information.
