Problems solved by technology

In some scenarios, if the number of REs occupied by UCI is large, the actual number of REs in PUSCH will decrease, and eventually PUSCH transmission may exceed the maximum bit rate limit, causing abnormal channel demodulation

Abstract

Embodiments of the present invention provide a UCI multiplexing configuration method, apparatus and device, and a computer readable storage medium. The method comprises of obtaining a bit length of a UCI needing to be multiplexed in a PUSCH, and a signal-to-noise ratio of the PUSCH; according to the signal-to-noise ratio, obtaining the corresponding transmission block size, modulation and code rate scheme and physical resource block number when the UCI is multiplexed on the PUSCH, and the corresponding target code rate of the UCI under the signal-to-noise ratio; obtaining a bit length, a transmission block size, a modulation and code rate scheme (MCS), a physical resource block number and a target code rate, obtaining a resource element (RE) number of the UCI under the target code rate according to the obtained bit length, the transmission block size, the modulation and code rate scheme (MCS), the physical resource block number and the target code rate, calculating a beta offset value of the PUSCH based on the obtained RE number, and generating a tower offset value when the UCI multiplexing configuration information multiplexes the UCI based on the tower offset value.

Description

Technical field[0001]The present invention relates to the field of communication technologies, and more particularly to a UCI multiplexing configuration, apparatus, device, and computer readable storage medium.Background technique[0002]In the 5G NR system, UCI (UPLINK CONTROL Information, Uplink Control Information) supports static and dynamic configuration types when Pusch (Physical Uplink Shared Channel, Physical Uplink Shared Channel) is multiplexed, and UCI information mainly includes: channel status information ( Channel State Information, CSI), and Acknowledgment, ACK, or negative confirmation (NACK) information is confirmed (NACK) information, or NEGATIVE ACKNOWLEDGMENT, NACK. The Peta offset BetaOffset calculation of the PUSCH directly affects the actual code rate of UCI and PUSCH. If the high-level signaling parameter beetaOffset configuration is unreasonable, it will cause UCI and PUSCH code control abnormalities. The UCI's BetaOffset value will affect the number of resour...
