Abstract

The invention discloses a top-down control information receiving method, device, and a storage medium, which belong to the field of communication. The method comprises the steps that a terminal receives BWP configuration information sent by a receiving net device; the terminal determines a target BWP positioned at unlicensed frequency based on the BWP configuration information, and the target BWPincludes sub-bands in the number of m; the terminal respectively monitors a target sequence on the sub-bands in the number of m; after the target sequence is monitored, the terminal monitors the top-down control information on all or part of the sub-bands in the number of m. The invention is advantageous in that after the target sequence is monitored, the terminal monitors the DCI on all or part of the sub-bands in the number of m, the searching times and searching consumption of the terminal at PDCCH can be effectively reduced, and unnecessary power and electric power consumption by the terminal can be prevented.

Description

technical field [0001] The present application relates to the communication field, and in particular to a DCI (Downlink Control Information, downlink control information) receiving method, sending method, device and storage medium. Background technique [0002] In the 5G NR (New Radio, new air interface) system, the concept of BWP (Bandwidth Part, bandwidth fragmentation) is introduced, that is, for a terminal, a frequency band is divided into several BWPs, and the terminal is configured within a period There are multiple BWPs, but there is only one activated (activated) BWP at the same time, and the terminal only monitors the DCI signaling on the activated BWP. [0003] After obtaining the activated BWP configured by the base station, the terminal can monitor the PDCCH (Physical Downlink Control Channel, physical downlink control channel) sent by the base station on the activated BWP and blindly detect DCI. Then, the terminal can receive the downlink data sent by the base ...
