1. A blind detection method for a control channel, performed by a terminal device and comprising:
obtaining downlink control information (DCI) of a plurality of subframes through blind detection of the control channel; and
determining validity of the DCI of the plurality of subframes in repetition times adopted in the blind detection of the control channel to obtain a decision result,
wherein the determining the validity of the DCI of the plurality of subframes in repetition times adopted in the blind detection of the control channel to obtain the decision result comprises:
determining validity of stored DCI according to the stored DCI and DCI of a current subframe in repetition times adopted in the blind detection of the control channel;
determining the stored DCI as non-false detection in a case that the stored DCI is the same as any DCI of the current subframe; and
determining the stored DCI as false detection in a case that the stored DCI is different from all of DCI of the current subframe.
