摘要： An interleaver and method of interleaving operate on data represented in a sequence of symbols to produce an interleaved sequence of symbols. The interleaver performs intra-block and inter-block permutations on the sequence of symbols. An encoder and method of encoding operate on data represented in a source sequence of symbols. The source sequence of symbols is encoded into a first sequence of codewords and interleaved using intra-block and inter-block permutations to produce a sequence of interleaved symbols. The sequence of interleaved symbols is encoded into a second sequence of codewords. A decoder and method of decoding operate on data represented in a sequence of received symbols. The sequence of received symbols comprises a formatted copy of the source sequence of symbols and the first and the second sequence of codewords.

摘要： A resource allocation method and a resource indication method for E-MBS system, and a mobile station using the same are proposed. The resource units of a first service flow are allocated following the end of the E-MBS MAP of the E-MBS region, along with the increasing of frequency domain index. When the edge of the E-MBS region in frequency domain is reached, the resource units of mth service flow are continued to be allocated from top frequency domain index in next time domain index, where m is an integer greater than or equal to 1. The resource units of m+1th service flow are allocated following the mth service flow, and such procedures are repeated until all service flows are allocated required resource units. The resource indication method indicates a specific service flow by absolute location in the E-MBS region formed based upon the resource allocation method.
