Abstract

The invention discloses a transmission method and device for a downlink control channel. The transmission method for a downlink control channel includes the steps: a terminal receives configuration information sent by a base station device, wherein the configuration information includes control resource set CORESET grouping information configured for the terminal by the base station device in thedownlink control channel monitoring occasion, and PDCCH (physical downlink control channel) candidate grouping information in at least one CORESET; when the configuration information includes the CORESET grouping information, the terminal determines at least one set of CORESET from the configuration information, and detects and receives at most one DCI (Downlink Control Information) from each of the at least one set of CORESET according to the specific DCI format expected by the terminal; and when the configuration information includes PDCCH candidate grouping information in the at least one CORESET, the terminal determines at least one group of PDCCH candidate from the configuration information, and detects and receives at most one DCI from each group of PDCCH candidate in the at least one group of PDCCH candidate according to the specific DCI format desired by the terminal.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method and equipment for transmitting a downlink control channel. Background technique [0002] In the LTE (Long Term Evolution, long-term evolution) system, the terminal monitors the downlink in the public search space and / or UE-specific (terminal-specific) search space according to the expected received DCI (Downlink Control Information, downlink control information) format (format). control channel. After receiving the desired DCI format, the terminal does not continue to blindly detect the desired DCI format. [0003] However, in the future wireless mobile communication system, the base station may configure one or more CORESE (Control Resource Set, Control Resource Set) for the terminal in a slot or a subframe, especially in order to enhance the reliability of the base station transmission, the base station It may be necessary to send the same DCI format ca...
