Abstract

The embodiment of the invention provides a transmission method of downlink control information, a terminal and network side equipment. The method comprises the following steps: a terminal determines resource configuration information corresponding to a control resource set; the terminal acquires blind detection information according to a first corresponding relation between the resource configuration information and the blind detection information, wherein the blind detection information comprises at least one of the length of downlink control information DCI, aggregation level of a candidatecontrol channel, and length of resource allocation field RA in the DCI; and the terminal receives the DCI sent by the network equipment on the control resource set according to the blind detection information. Through the transmission method provided by the embodiment of the invention, the flexibility of the resource indication can be improved, and the blind detection efficiency is improved.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a method for transmitting downlink control information, a terminal and network side equipment. Background technique [0002] In a Long Term Evolution (LTE) system, before receiving or sending data, a terminal device needs to know the downlink control information (Downlink control channel, DCI) configured by the network side device for the terminal. The DCI is transmitted through the physical downlink control channel (Physical Downlink Control channel, PDCCH) bearer. [0003] In a specific communication process, the terminal obtains the DCI by performing blind detection on the PDCCH, and then according to the starting symbol position of the Physical Downlink Shared Channel (PDSCH), combined with the DCI carried in the PDCCH, it is displayed on the PDSCH Send data on. [0004] In the fifth generation mobile communication (the 5th Generation Mobile Communication, 5G) ne...
