Abstract

A method and device for detecting a downlink control channel are used to provide a method for determining the total number of PDCCH candidates. The method includes: the mobile device determines an activated bandwidth part BP; the activated BP belongs to a carrier; the mobile device determines a downlink control channel candidate detectable by the mobile device according to the activated BP or a system parameter corresponding to the activated BP The total number; wherein, the total number of downlink control channel candidates is greater than or equal to a preset threshold; the mobile device detects the downlink control channel according to the total number of downlink control channel candidates.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a method and device for detecting a downlink control channel. Background technique [0002] Downlink Control Information (DCI) has multiple formats, but the mobile device does not know in advance which format of DCI is carried by the received Physical Downlink Control Channel (PDCCH), nor does it know the DCI Which PDCCH candidate is used for transmission, so the mobile device needs to perform PDCCH blind detection on all PDCCH candidates to receive the corresponding DCI. [0003] However, the way of determining the total number of PDCCH candidates in the Long Term Evolution (Long Term Evolution, LTE) system is not suitable for the fifth generation (5th Generation, 5G) New Radio (New Radio, NR) system. Contents of the invention [0004] The present application provides a method and equipment for detecting downlink control channels, which are...
