Abstract

The present application relates to a physical downlink control channel detection method, device, device, and storage medium; wherein, the method includes: based on the received PDCCH data, obtaining the de-rate matching data of multiple candidate sets; calculating each of the The posterior probability value of the solution rate matching data of candidate set; Based on the size of each described posterior probability value, select the solution rate matching data of the candidate set corresponding to the M largest posterior probability values; Wherein, M is A positive integer, and M is less than the number of the candidate sets; the de-rate-matching data of the candidate sets corresponding to the first M largest posterior probability values ​​are used as the data to be decoded, and the decoding process is performed. The present application is used to solve the problem of large time delay caused by the decoding method in the related art.

Description

Technical field [0001] The present application relates to the field of mobile communication, and more particularly to a method, apparatus, device, and storage medium of a physical downlink control channel. Background technique [0002] In the mobile communication system, the PDCCH physical downlink control channel data is required before the PDSCH physical downlink shared channel data and the PUSCH are shared, and the corresponding DCI downlink control information is obtained to obtain the specific PDSCH and PUSCH. Resource configuration, PDCCH blind detection is often required in mobile communication systems. [0003] Currently, PDCCH physical downlink control channel blind detection is usually used to Polar decoding. The PDCCH receiving end obtains a balanced data after the channel estimation and equalization process, and the corresponding data is selected from the equalized data from the possible candidate set, and then obtain the decoded, descramble, and decreased data to obt...
