The method includes: receiving, by a terminal device, a first value broadcast by a network device, the first value being configured for the terminal device to select a carrier; determining, by the terminal device, a target uplink carrier from a first uplink carrier and a second uplink carrier according to the first value, the first uplink carrier and the second uplink being configured for the terminal device to transmit data and having different frequencies; and sending, by the terminal device, uplink data to the network device over the target uplink carrier. ## Claims ### Claim 1 A method for transmitting information, comprising: receiving, by a terminal device, a first value broadcast by a network device, the first value being configured for the terminal device to select a carrier; selecting, by the terminal device, a target uplink carrier from a first uplink carrier and a second uplink carrier according to the first value, the first uplink carrier and the second uplink carrier being configured for the terminal device to transmit data and having different frequencies from each other; and sending, by the terminal device, uplink data to the network device over the target uplink carrier, wherein the method further comprises: obtaining, by the terminal device, a second value, the second value being configured to be compared with the first value, and a comparison result between the first value and the second value indicating that the target uplink carrier is one of the first uplink carrier and the second uplink carrier, wherein the target uplink carrier is selected according to the comparison result, wherein obtaining, by the terminal device, a second value comprises: receiving, by the terminal device, the second value sent by the network device, wherein the second value is determined by the network device according to a load condition of the first uplink carrier and the load condition of the second uplink carrier, wherein when a load of the first uplink carrier is less than the load of the second uplink carrier, the second value is greater than a third value; and when the load of the first uplink carrier is greater than or equal to the load of the second uplink carrier, the second value is less than or equal to the third value, wherein the third value is a base value used by the network device to determine the second value. ### Claim 2 (depends on 1) The method according to claim 1, wherein when the comparison result is that the first value is greater than the second value, the comparison result indicates that the target uplink carrier is the first uplink carrier; and when the comparison result is that the first value is less than or equal to the second value, the comparison result indicates that the target uplink carrier is the second uplink carrier. ### Claim 3 (depends on 1) The method according to claim 1, wherein each of the first value, the second value and the third value has a value range of 0 to 1. ### Claim 4 (depends on 1) The method according to claim 1, wherein a signal measurement quality of the terminal device is greater than a threshold value broadcast by a system. ### Claim 5 (depends on 1) The method according to claim 1, wherein each of the first value, the second value and the third value has a value range of 0 to 10. ### Claim 6 A method for transmitting information, comprising: determining, by a network device, a first value, the first value being configured for a terminal device to determine a target uplink carrier from a first uplink carrier and a second uplink carrier, and the first uplink carrier and the second uplink carrier being configured for the terminal device to transmit data and having different frequencies; and sending, by the network device, the first value to the terminal device in a broadcast manner; wherein the method further comprises: determining, by the network device, a second value according to a load condition of the first uplink carrier and the load condition of the second uplink carrier, so that the terminal device determines the target uplink carrier from the first uplink carrier and the second uplink carrier by comparing the first value and the second value; and sending, by the network device, the second value to the terminal device, wherein when a load of the first uplink carrier is less than the load of the second uplink carrier, the second value is greater than a third value; and when the load of the first uplink carrier is greater than or equal to the load of the second uplink carrier, the second value is less than or equal to the third value, wherein the third value is a base value used by the network device to determine the second value. ### Claim 7 (depends on 6) The method according to claim 6, wherein each of the first value, the second value and the third value has a value range of 0 to 1. ### Claim 8 (depends on 6) The method according to claim 6, wherein a signal measurement quality of the terminal device is greater than a threshold value broadcast by a system. ### Claim 9 (depends on 6) The method according to claim 6, wherein each of the first value, the second value and the third value has a value range of 0 to 10. ### Claim 10 A terminal device, comprising: a transceiver, configured to receive a first value broadcast by a network device, the first value being configured for the terminal device to select a carrier; and a processor, configured to determine a target uplink carrier from a first uplink carrier and a second uplink carrier according to the first value, the first uplink carrier and the second uplink carrier being configured for the terminal device to transmit data and having different frequencies, wherein the transceiver is further configured to send uplink data to the network device over the target uplink carrier, wherein one of the processor and the transceiver is further configured to: obtain a second value before the processor determines the target uplink carrier, the second value being configured to be compared with the first value, and a comparison result between the first value and the second value indicating that the target uplink carrier is one of the first uplink carrier and the second uplink carrier, wherein the processor is configured to: determine the target uplink carrier according to the comparison result, wherein obtaining the second value comprises: receiving the second value sent by the network device, wherein the second value is determined by the network device according to a load condition of the first uplink carrier and the load condition of the second uplink carrier, wherein when a load of the first uplink carrier is less than the load of the second uplink carrier, the second value is greater than a third value; and when the load of the first uplink carrier is greater than or equal to the load of the second uplink carrier, the second value is less than or equal to the third value, wherein the third value is a base value used by the network device to determine the second value.
