Abstract

The embodiment of the invention provides a downlink control information processing method and device. When the UE detects that the number of DCI in a DCI set contained in a PDCCH is greater than a preset number threshold, the UE sends the DCI to the PDCCH. And respectively establishing corresponding DCI analysis tasks on the at least two target CPU cores, and respectively executing the corresponding DCI analysis tasks based on each target CPU core, each DCI analysis task being respectively used for analyzing DCI in different DCI subsets of the DCI set. According to the invention, when the number of DCI contained in the PDCCH is large, the time consumed when the UE analyzes the DCI can be effectively shortened, and thus the UE can be ensured to carry out data transmission in time.

Description

technical field [0001] The embodiments of the present application relate to the field of communication technologies, and in particular, to a method and device for processing downlink control information (Downlink Control Information, DCI for short). Background technique [0002] In a communication system, after channel multiplexing, DCI belonging to different user equipments (User Equipment, referred to as UE) will be carried together on a physical downlink control channel (Physical Downlink Control channel, referred to as PDCCH), which is used to indicate uplink physical information to each UE. Scheduling information of a shared channel (Physical Uplink Shared Channel, PUSCH for short) or a physical downlink shared channel (Physical Downlink Shared Channel, PDSCH for short), so that each UE can send or receive data. [0003] Wherein, any UE needs to parse out its own DCI from the PDCCH after detecting the PDCCH information, and since the UE does not know the format and loca...
