Method for detecting the validity of downlink control information in telecommunication user equipment, decoder and baseband receiver for performing same |
摘要 |
The invention relates to a method for detecting the validity of downlink control information in telecommunication user equipment and to a decoder and baseband receiver designed to perform that method. The object of avoiding falsely detecting payload data and misinterpreting them is achieved by reverse encoding a bit output sequence of a Viterbi decoder; determining hard bits from a soft-bit input sequence of the decoder; determining a bit count of real received bits; comparing the re-encoded bit stream to the determined hard bit stream and counting the number of mismatches to obtain an error count; comparing a bit error rate which is defined as a quotient of the error count and the bit count against a predefined threshold value; and rejecting the payload as invalid if said bit error rate is above said threshold value, even if a cyclic redundancy check of the payload gives a correct result. |
