Problems solved by technology

[0004] However, when a terminal device has multiple UCIs that need to be reported to the access network device at the same time, it is easy to generate UCI reporting conflicts, which will cause all of the multiple UCIs to fail to be reported, affecting data transmission performance and making it difficult to guarantee service requirements

Abstract

Embodiments of the application provide an information transmission method, a terminal device and an access network device. The information transmission method provided in the embodiments of the application may comprise the steps that: the terminal device determines N pieces of UCI that need to be transmitted in a same time unit, and transmits M pieces of UCI to the access network device on the basis of priorities of the N pieces of UCI, wherein N is an integer greater than or equal to 2, the N pieces of UCI include at least one of beam-forming information, buffer state report information and scheduling request information, the priorities of the M pieces of UCI are greater than that of the other N-M pieces of UCI in the N pieces of UCI, and M is a positive integer less than or equal to N. The embodiments of the application are capable of effectively preventing a conflict in reporting the UCI, ensuring the success rate of reporting the UCI, and effectively ensuring data transmission performance and service demand.
