Abstract

Embodiments of the present invention provide a method for transmitting downlink control information, a terminal, and a network side device. The method includes: the terminal determines resource configuration information corresponding to the control resource set; the terminal obtains the blind detection information according to a first correspondence between the resource configuration information and blind detection information, and the blind detection information includes: downlink At least one of the length of the control information DCI, the aggregation level of the candidate control channel, and the length of the resource allocation field RA in the DCI; the terminal receives the information sent by the network side device on the control resource set according to the blind detection information DCI. The embodiments of the present invention can improve the flexibility of resource indication, thereby improving the efficiency of blind detection.

Description

Technical field [0001] The present invention relates to wireless communication technology, in particular to a transmission method, terminal and network side equipment of downlink control information. Background technique [0002] In the Long Term Evolution (LTE) system, before receiving or sending data, a terminal device needs to know the downlink control information (Downlink control channel, DCI) that the network side device configures for the terminal. The DCI uses the physical downlink control channel. (Physical Downlink Control channel, PDCCH) bearer. [0003] In a specific communication process, the terminal obtains DCI by blindly detecting the PDCCH, and then according to the starting symbol position of the physical downlink shared channel (Physical Downlink Shared Channel, PDSCH), combined with the DCI carried in the PDCCH in the PDSCH Send data on. [0004] In the 5th Generation Mobile Communication (5G) new radio access technology (New Radio Access Technology, NR), the im...
