Example Embodiment

[0025]The above objects, features, and advantages of the present disclosure will be more clearly understood, and the scheme of the present disclosure will be further described below. It should be noted that the features of the present disclosure may be combined with each other in the case of an unable conflict.

[0026]A lot of specific details are set forth in the following description to fully understand the present disclosure, but the present disclosure may also employ other different from the described manner; clear, the embodiments in the specification are only part of the embodiments of the present disclosure. Not all embodiments.

[0027]Under the 5G system, when the Uplink Shared Channel, PUSCH is authorized, the User Equipment (UE) also has a base station on the UPLink Controlinformation (UCI), and the UCI can be multiplexed. Transfer on the PUSCH, the base station receives the data transmitted by the user equipment needs to be used in accordance with the scheduling information. ...

Abstract

The embodiment of the invention relates to an information decoding method and device, equipment and a medium, and the method is applied to a base station, and comprises the steps: obtaining initial scheduling information, decoding to-be-decoded information based on the initial scheduling information, and obtaining first decoding information, wherein the to-be-decoded information is information sent by the user equipment after coding uplink control information based on the initial scheduling information and multiplexing an uplink physical shared channel; if it is determined that both the first decoding information and the initial scheduling information are wrong, repairing the initial scheduling information to obtain target scheduling information; and decoding the to-be-decoded information based on the target scheduling information to obtain second decoding information. By adopting the technical scheme, the decoding error caused by the abnormity of the scheduling information in the existing scheme is solved, the decoding accuracy and reliability are improved, the robustness of the system is improved, lower application layer time delay is realized, and the performance of the system is further improved.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to an information decoding method, device, equipment, and medium. Background technique [0002] The new generation of wireless technology 5G_NR (5G New Radio) is a global 5G standard based on a new air interface design based on Orthogonal Frequency Division Multiplexing (OFDM). 5G technology has ultra-low latency and high reliability characteristics. [0003] Under the 5G system, when the physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) has authorization, the user equipment (User Equipment, UE) also has uplink control information (Uplink Control Information, UCI) to report to the base station, at this time UCI can be multiplexed Transmission is performed on the PUSCH, and the data transmitted by the user equipment received by the base station needs to be demultiplexed according to the scheduling information. In the 5G system, the method...
