Abstract: A control channel may be used to transmit control information, such as Downlink Control Information (DCI), to a mobile device from a network component, such as a base station or a base node. The mobile device may use a blind decoding scheme to detect DCIs. A DCI may be falsely detected by the mobile device. According to some embodiments, data that has been decoded by a blind decoder, from buffer data for a candidate control channel, is re-encoded. The re-encoded data is compared to buffer data for the control channel. The decoded data is treated as control information dependent on the comparison of the re-encoded data with the buffer data. In some embodiments, comparing the re-encoded data to the buffer data includes generating a metric as a function of a degree of similarity between the re-encoded data and the buffer data. The metric may be compared to a threshold.
