Abstract

The invention relates to a physical downlink control channel detection method and device, equipment and a storage medium. The method comprises the following steps: based on received PDCCH (Physical Downlink Control Channel) data, obtaining rate de-matching data of a plurality of candidate sets; calculating a posterior probability value of rate de-matching data of each candidate set; based on the magnitude of each posterior probability value, selecting rate de-matching data of the candidate set corresponding to the first M maximum posterior probability values; wherein M is a positive integer, and M is smaller than the number of the candidate sets; and taking the rate de-matching data of the candidate set corresponding to the first M maximum posterior probability values as to-be-decoded data, and performing decoding processing. The method and the device are used for solving the problem of relatively large time delay caused by a decoding method in related arts.

Description

technical field [0001] The present application relates to the technical field of mobile communication, and in particular to a detection method, device, equipment and storage medium of a physical downlink control channel. Background technique [0002] In a mobile communication system, before deciphering the PDSCH physical downlink shared channel data and the PUSCH uplink shared physical channel data, it is necessary to decipher the PDCCH physical downlink control channel data and obtain the corresponding DCI downlink control information to obtain the specific information of PDSCH and PUSCH. For resource configuration, PDCCH blind detection is usually required in a mobile communication system. [0003] At present, the blind detection of the PDCCH physical downlink control channel usually uses Polar decoding. The PDCCH receiving end obtains the equalized data after channel estimation and equalization processing, selects the corresponding data from the equalized data according ...
