Information transmission method, device and equipment and computer readable storage medium

Abstract

The invention discloses an information transmission method, device and equipment and a computer readable storage medium, relates to the technical field of communication, and aims to ensure the transmission performance of UCI. The method comprises: when a PUCCH bearing a UCI overlaps with at least one PUSCH in a time domain, selecting a first PUSCH from the at least one PUSCH, the first PUSCH being used for bearing the UCI; if the time domain of the first PUSCH and the time domain of the second PUSCH are overlapped on the same carrier wave, the UCI is transmitted on the first PUSCH and the second PUSCH; or if the first PUSCH and the second PUSCH are overlapped on the same carrier in time domain, when the first PUSCH is stopped or cancelled, the UCI is transmitted on the second PUSCH. According to the embodiment of the invention, the transmission performance of the UCI can be ensured.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to an information transmission method, device, equipment and computer-readable storage medium. Background technique [0002] In 5G R15 NR (New Radio, new air interface), from the perspective of reducing PAPR (Peak to Average Power Ratio, peak-to-average power ratio) and CM (Connection Management, connection management), it does not support PUCCH (Physical Uplink Control Channel, physical uplink Control Channel) and PUSCH (Physical Uplink Shared Channel, Physical Uplink Shared Channel) are transmitted simultaneously (time-domain resources overlap), and simultaneous transmission of multiple overlapping PUCCHs on the same carrier is also not supported. [0003] When all or part of symbols of a PUCCH and a PUSCH overlap, it is necessary to judge whether the first symbol of the earliest starting channel in the PUCCH and PUSCH satisfies a predefined time condition (timel...

AI Technical Summary

Problems solved by technology

[0010] When the PUCCH overlaps with an earlier PUSCH in time and UCI needs to be transferred to the earlier PUSCH for transmission, if the earlier PUSCH is stopped or canceled by the subsequent PUSCH, the UCI on it will also be transmitted. It cannot be transmitted to the base station side normally, so that the base station cannot obtain timely and correct feedback information such as HARQ-ACK, CSI, SR and other information of the downlink transmission that has occurred

[0011] At present, there is no clear way how to solve the problem of UCI being discarded in the above situation
