Abstract

The invention relates to a blind detection method for a control channel, a terminal, a network element and a storage medium, and the method comprises the steps: obtaining downlink control informationDCI of a plurality of subframes through the blind detection of the control channel; and within the repeated sending times of the control channel, performing validity judgment on the DCI of the plurality of subframes to obtain a judgment result. According to the embodiment of the invention, the effectiveness judgment is carried out on the DCI of the plurality of subframes obtained by blind detection within the repeated sending times of the control channel to obtain the judgment result of whether the DCI is the false detection or not, so that the false detection probability is reduced, and the blind detection accuracy of the control channel is improved.

Description

technical field [0001] The present disclosure relates to the technical field of communications, and in particular to a blind detection method for a control channel, a terminal, a network element, and a storage medium. Background technique [0002] In the communication system, the downlink control information (Downlink Control Information, DCI) is obtained by using the blind detection of the control channel, and the scheduling information for the downlink data channel or the uplink data channel, uplink power control information, information related to uplink preamble transmission, and semi-persistent scheduling are obtained. freed. However, there is false detection in the blind detection of the control channel, that is, the base station does not send the DCI to the terminal, but the terminal detects the DCI, which will cause unnecessary operations. Contents of the invention [0003] In view of this, the present disclosure proposes a method for blind detection of a control ...
