Claim Text:
1. A method for communication information transmission, comprising: transmitting, by a transmitter of a user equipment, communication information to a base station; obtaining, by a processor of the user equipment, a first backoff upper limit, when the communication information fails to be transmitted to the base station, according to a number of times the transmission has failed; and determining, by the processor of the user equipment, a backoff upper limit according to the first backoff upper limit, and selecting, by the processor of the user equipment, a backoff time for retransmitting the communication information according to the backoff upper limit, wherein a numerical value of the first backoff upper limit increases with an increase in the number of times the transmission has failed; and the obtaining, by the processor of the user equipment, the first backoff upper limit according to the number of times the transmission has failed comprises: obtaining, by the processor of the user equipment, a backoff parameter according to a signal transmitted from the base station, wherein the backoff parameter is an allocation interval of competed resources required for transmitting the communication information, and obtaining, by the processor of the user equipment, the first backoff upper limit according to the following formula I: where i represents the number of times the transmission has failed, T1 represents the first backoff upper limit, and T2 represents the backoff parameter.
