Abstract: A control channel encoder, e.g., in a UMB system, uses a channel structure that can efficiently transmit more information bits, yet achieve sufficient detection and false alarm performance. A control channel encoder can use a fixed encoder packet size, tail-biting convolutional coding, and Cyclical Redundancy Check (CRC). A control channel decoder can use Viterbi Decoding and a circular trellis check.

Abstract: Provided is a multi-layered transmission technique in which a signal indicating that a transmitted data packet has been correctly received by the receiver is provided from one communication layer to another. Based on that signal, the second layer releases the corresponding data from its retransmission buffer. As result, storage requirements for data waiting to be retransmitted, if necessary, often can be significantly reduced.
