Abstract

The invention discloses a downlink control information detection method, a downlink control information transmission method, a terminal and a network device. The downlink control information detectionmethod comprises the following steps: obtaining indication information used for indicating a candidate downlink control information DCI load size; and performing blind detection on a physical downlink control channel PDCCH according to the candidate DCI load size indicated by the indication information so as to determine the DCI transmitted in the PDCCH. The terminal disclosed by the invention obtains the indication information used for indicating the candidate DCI load size, and performs the blind detection on the PDCCH according to the candidate DCI load size, so that the blind detection complexity can be reduced, and the blind detection times can be reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a downlink control information detection method, transmission method, terminal and network equipment. Background technique [0002] In the long term evolution (Long Term Evolution, hereinafter referred to as: LTE) system, and the future fifth generation (5Generation, hereinafter referred to as: 5G) communication system, or called the new air interface (New Radio, hereinafter referred to as: NR) system, In order to make channel design more flexible, terminal blind detection is introduced. Specifically, on the premise of information such as the location of the physical transmission resource where the location control signaling is located, the size of the occupied resource, etc., the terminal performs tentative detection through various assumptions until the control signaling is decoded correctly. [0003] In the LTE system, before the network device sends the Physic...
