Abstract

The present disclosure relates to a method for blind detection of a control channel, a terminal, a network element, and a storage medium, wherein the method includes obtaining downlink control information DCI of multiple subframes through blind detection of the control channel; repeating in the control channel Within the number of sending times, the validity judgment is performed on the DCIs of the multiple subframes to obtain a judgment result. In the embodiment of the present disclosure, within the number of repeated transmissions of the control channel, the validity judgment is made on the DCI of multiple subframes obtained by blind detection to obtain the judgment result of whether the DCI is a false detection, thereby reducing the probability of false detection and improving control. Channel blind detection accuracy.

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 ...
