Problems solved by technology

In the 5G system, the method of multiplexing UCI to the uplink shared channel (ULSCH) is different from that of the 4G system. The demultiplexing process of the 5G system is different from that of the 4G system. The resource element (Resource Element, RE ) position, which may cause a slight abnormality in the scheduling information and cause a demultiplexing error, that is, a decoding error of ULSCH and UCI
At present, the decoding errors caused by abnormal scheduling information are ignored or discarded, which cannot solve the problem

Embodiment Construction

[0025] In order to more clearly understand the above objects, features and advantages of the present disclosure, the solutions of the present disclosure will be further described below. It should be noted that, in the case of no conflict, the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

[0026] In the following description, many specific details are set forth in order to fully understand the present disclosure, but the present disclosure can also be implemented in other ways than described here; obviously, the embodiments in the description are only some of the embodiments of the present disclosure, and Not all examples.

[0027] 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 multi...

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...
