In response to determining that the waiting duration is greater than a threshold, the access network device can then determine a second subframe quantity that is within the preset subframe quantity value range and that enables the waiting duration to be less than or equal to the threshold. The access network device can then send a first uplink authorization instruction to the terminal, where the first uplink authorization instruction is used to instruct the terminal to send uplink data of the second subframe quantity. ## Claims ### Claim 1 A data transmission method, comprising: obtaining, by an access network device, a waiting duration corresponding to transmitting uplink data of a first subframe quantity by a terminal, wherein the first subframe quantity is a subframe quantity with the greatest scheduling efficiency within a preset subframe quantity value range when the access network device schedules the terminal to transmit the uplink data, and wherein the waiting duration is a duration that exists after the terminal transmits the uplink data and that extends from a time at which the terminal switches to a listening state to a time at which the terminal detects an uplink authorization instruction; in response to determining that the waiting duration is greater than a threshold, determining, by the access network device within the preset subframe quantity value range, a second subframe quantity that enables the waiting duration to be less than or equal to the threshold; and sending, by the access network device, a first uplink authorization instruction to the terminal, wherein the first uplink authorization instruction is used to instruct the terminal to send uplink data of the second subframe quantity. ### Claim 2 (depends on 1) The method according to claim 1, wherein the method further comprises: in response to determining that the waiting duration is less than or equal to the threshold, sending, by the access network device, a second uplink authorization instruction to the terminal, wherein the second uplink authorization instruction is used to instruct the terminal to send the uplink data of the first subframe quantity. ### Claim 3 (depends on 1) The method according to claim 1, wherein the method further comprises: in response to determining that the second subframe quantity does not exist within the preset subframe quantity value range, sending, by the access network device, a second uplink authorization instruction to the terminal, wherein the second uplink authorization instruction is used to instruct the terminal to send the uplink data of the first subframe quantity. ### Claim 4 (depends on 1) The method according to claim 1, wherein the determining the second subframe quantity comprises: for any subframe quantity within the preset subframe quantity value range, in response to determining, by the access network device, that a waiting duration corresponding to transmitting uplink data of the subframe quantity by the terminal is less than or equal to the threshold, determining the subframe quantity as the second subframe quantity. ### Claim 5 (depends on 1) The method according to claim 1, wherein the threshold is 0. ### Claim 6 A data transmission method, comprising: receiving, by a terminal, a first uplink authorization instruction from an access network device, wherein the first uplink authorization instruction is used to instruct the terminal to send uplink data of a second subframe quantity, and wherein the second subframe quantity is a subframe quantity that enables a waiting duration corresponding to transmitting the uplink data by the terminal to be less than or equal to a threshold and that is determined within a preset subframe quantity value range by the access network device when a waiting duration corresponding to transmitting uplink data of a first subframe quantity by the terminal is greater than the threshold; and sending, by the terminal, the uplink data of the second subframe quantity. ### Claim 7 (depends on 6) The method according to claim 6, wherein the threshold is 0. ### Claim 8 A communications apparatus, comprising: a processing unit, configured to obtain a waiting duration corresponding to transmitting uplink data of a first subframe quantity by a terminal, wherein the first subframe quantity is a subframe quantity with the greatest scheduling efficiency within a preset subframe quantity value range when the terminal is scheduled to transmit the uplink data, and wherein the waiting duration is a duration that exists after the terminal transmits the uplink data and that extends from a time at which the terminal switches to a listening state to a time at which the terminal detects an uplink authorization instruction; the processing unit, configured to determine, in response to determining that the waiting duration is greater than a threshold, a second subframe quantity that is within a preset subframe quantity value range and that enables the waiting duration to be less than or equal to the threshold; and a transceiver unit, configured to send a first uplink authorization instruction to the terminal, wherein the first uplink authorization instruction is used to instruct the terminal to send uplink data of the second subframe quantity. ### Claim 9 (depends on 8) The apparatus according to claim 8, wherein the transceiver unit is further configured to: in response to determining that the waiting duration is less than or equal to the threshold, send a second uplink authorization instruction to the terminal, wherein the second uplink authorization instruction is used to instruct the terminal to send the uplink data of the first subframe quantity. ### Claim 10 (depends on 8) The apparatus according to claim 8, wherein the transceiver unit is further configured to: in response to determining that the second subframe quantity does not exist within the preset subframe quantity value range, send a second uplink authorization instruction to the terminal, wherein the second uplink authorization instruction is used to instruct the terminal to send the uplink data of the first subframe quantity. ### Claim 11 (depends on 8) The apparatus according to claim 8, wherein the processing unit is further configured to: for any subframe quantity within the preset subframe quantity value range, in response to determining that a waiting duration corresponding to transmitting the uplink data of the subframe quantity by the terminal is less than or equal to the threshold, determine the subframe quantity as the second subframe quantity. ### Claim 12 (depends on 8) The apparatus according to claim 8, wherein the threshold is 0.
