A method, device and readable storage medium for preventing pdcch false detection
A false detection and blind detection technology, which is applied to the device dedicated to the receiver, error prevention, and forward error control, etc., can solve the problems of downlink HARQ feedback errors, errors, and unpredictable high-level status, so as to prevent PDCCH errors. detection, improve detection accuracy and system transmission efficiency, and improve the effect of user experience

[0104] Such as figure 2 A method for preventing PDCCH false detection is shown.
[0105] Step S201, execute steps S101 to S104. Determine the ratio of the different bits between the coded data and the result of the hard decision relative to the soft bit data, and determine the signal-to-noise ratio of the blind detection data.
[0106] Step S202, judging whether the ratio is greater than threshold 1, if yes, go to step S203, if not, go to step S205.
[0107] Step S203, judging whether the SNR is greater than the SNR threshold 3, if yes, go to step S204, if not, go to step S205;
[0108] In step S204, it is directly determined that it is a false detection, and the process ends.
[0109] Step S205, judging whether the SNR is less than the SNR threshold 3 and greater than the SNR threshold 4, if yes, go to step S206.
[0110] Step S206, judging whether the following two conditions are met at the same time: the Rmax of the configured PDCCH is less than the threshold 5, and th...
