Information processing method, device, terminal, chip and storage medium

Abstract

The embodiment of the invention discloses an information processing method, a device, a terminal, a chip and a storage medium. The information processing method comprises the following steps: determining a candidate physical downlink control channel (PDCCH), and a data length and a rate matching mode corresponding to the candidate PDCCH according to a preset configuration parameter; when the current candidate PDCCH is subjected to decoding processing, determining a target candidate PDCCH from the candidate PDCCHs which are subjected to decoding processing; wherein the target candidate PDCCH and the current candidate PDCCH have overlapped data; according to a first data length and a first rate matching mode corresponding to the target candidate PDCCH, and a second data length and a second rate matching mode corresponding to the current candidate PDCCH, judging whether a preset multiplexing condition is satisfied; if it is judged that the preset multiplexing condition is met, determining a data multiplexing mode corresponding to the current candidate PDCCH; and decoding the current candidate PDCCH according to the data multiplexing mode.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to an information processing method and device, a terminal, a chip and a storage medium. Background technique [0002] A new radio (New Radio, NR) system transmits downlink control information on a physical downlink control channel (Physical Downlink Control Channel, PDCCH), and a terminal detects whether there is a PDCCH from a network in a search space through blind detection. Specifically, in the blind detection process, the user equipment (User Equipment, UE) determines, according to the search space parameters, a group of PDCCH candidates corresponding to the search space, and the initial Control Channel Element (Control Channel Element, CCE) index, aggregation degree, and then decoding each candidate PDCCH, after decoding all PDCCH candidates, the UE can know which candidate carries the PDCCH. [0003] When performing blind detection based on all PDCCH c...

AI Technical Summary

Problems solved by technology

[0003] When performing blind detection based on all PDCCH candidates, since different PDCCH candidates may have the same starting CCE index position, different PDCCH candidates may have partial data overlap, which will cause defects in redundant operations , so that the terminal decoding delay time is long, resulting in waste of terminal processing power consumption
