Method, apparatus, and system for communication information transmission

Abstract

A method, apparatus, and system for communication information transmission are provided in the embodiments of the present invention. The method comprises: communication information is transmitted to a base station (BS); when the communication information fails to be transmitted to the BS, a first backoff upper limit is obtained according to the number of times the transmission has failed; a backoff upper limit is determined according to the first backoff upper limit, and a backoff time of retransmitting the communication information is selected according to the backoff upper limit. In the embodiments of the present invention, terminal can obtain the proper backoff upper limit according to the number of times it has failed to transmit the communication information, thereby reducing the latency of its uplink data transmission.

AI Technical Summary

Benefits of technology

This approach reduces transmission delays by allowing terminals to choose appropriate backoff times based on their specific failure conditions and allocates resources to minimize competition, thereby enhancing communication efficiency.

Problems solved by technology

When plural terminals transmit random access signals to a base station, the plural terminals simultaneously make use of the same and single competed resource, and this will cause competition conflict that leads to failure of service transmissions of the plural terminals.

However, for partial terminals that have failed the competition, their failure in the competition may not be caused by heavy network load, in which case there is no need to wait for a relatively long backoff time.

Nevertheless, according to the current mechanism, each terminal that has failed the competition inevitably randomly selects the backoff time according to this maximum backoff upper limit, whereby each terminal may select a relatively long backoff time, thus leading to delay in the transmission of uplink data by the terminals.
