摘要： Techniques are provided for a demodulation and decoding method and apparatus for a given user equipment device to receive a one or more Orthogonal Frequency Division Multiplex (OFDM) symbols over a control channel, where the OFDM symbols comprise a plurality of resource element groups distributed in time and frequency that are combined to form control channel elements. Those resource element groups that form specific control channel elements for the user equipment device and those resource element groups that form common control channel elements for one or more user equipment devices including the given user equipment device are identified. The resource element groups that form the specific control channel elements and the resource element groups that form the common control channel elements are demodulated to generate encoded control messages comprising one or more control channel elements.

摘要： Techniques are provided for decoding tail-biting convolutional codes by using information within the received data stream that traditionally has not been used or been available to the convolutional decoder, e.g., cyclic redundancy check (CRC) and bit information known by both the transmitter and receiver. Further, a single parallel trace-back is used that reduces implementation complexity. In addition, the least reliable decisions made during forward processing may be reversed in order to generate additional possible codeword candidates. These techniques can be used to reduce false detection rates (FDRs) and/or detection error rates (DERs).
摘要翻译：提供了通过使用传统上没有被使用或可用于卷积解码器的接收数据流中的信息来解码尾部卷积码的技术，例如循环冗余校验（CRC）和由发射机和接收机已知的比特信息。此外，使用单个并行跟踪来降低实现复杂度。另外，为了生成额外的可能的码字候选，在正向处理期间做出的最不可靠的决定可以颠倒。这些技术可用于降低错误检测率（FDR）和/或检测错误率（DER）。
