Abstract

The invention relates to a blind detection control method and device, a base station, user equipment and a storage medium, and relates to the technical field of communication. The method comprises thefollowing steps: for an MPDCCH or an NPDCCH, determining a target PDCCH for sending downlink control information DCI at a base station side according to a pre-specified PDCCH set or a pre-configuredPDCCH retention period, and then sending the DCI to user equipment by using the target PDCCH; and correspondingly, on the user equipment side, determning a target PDCCH needing blind detection according to a pre-specified PDCCH set or a pre-configured PDCCH retention period, and using the target PDCCH for carrying out blind detection on DCI. According to the invention, the number of MPDCCHs or NPDCCHs required to be subjected to blind detection by user equipment can be reduced, so that the blind detection complexity of the user equipment can be reduced, and the blind detection power consumption is reduced.

Description

technical field [0001] The present disclosure relates to the technical field of communications, and in particular, to a blind detection control method, device, base station, user equipment, and storage medium. Background technique [0002] eMTC (Enhanced Machine-Type Communications, enhanced machine type communication) and NB-IoT (Narrow Band Internet of Things, narrowband Internet of Things) are two types of cellular Internet of Things defined by 3GPP (3rd Generation Partnership Project, third generation partnership project) Technology, reducing terminal complexity and power consumption is an important issue of common concern for the above two technologies. [0003] Taking eMTC as an example, MPDCCH (MTC Physical Downlink Control Channel, MTC Physical Downlink Control Channel) is defined in eMTC to dynamically schedule PDSCH (Physical Downlink Shared Channel, Physical Downlink Shared Channel) and PUSCH (Physical Uplink Shared Channel, Physical Uplink Shared Channel) ). Th...
