Abstract:
A receiving Incremental Redundancy Radio Link Protocol module (receiving IRLP module) for a receiver, comprising:a receive transport module that receives soft decision information from a layer 1 protocol; a quantizer that converts the soft-decision information into a q level representation, where q is a design parameter that trades off receiver memory requirements against system performance and where, for a q level quantization, the memory requirements at the receiver per bit are given by log2q; a decoder that receives at least the q level representation of the soft decision information and decodes the at least the q level representation of the soft decision information to yield a decoded data block, wherein the decoded data block comprises error detection bits of a frame check sequence and a service data unit (SDU); a frame check sequence decoder that computes a frame check sequence of the SDU and indicates to the receiving IRLP module whether the SDU passed the frame check; and a deblocking module that constructs a deliverable data block by de-concatenating the SDU and the frame check sequence, wherein the de-concatenated SDU is the deliverable data block.
