Encoding of data for transmission

摘要

A data encoding method for encoding a sequence of N input blocks of bits into an output block for transmission includes adding an L-bit control indicator, indicating whether the sequence contains any control blocks, and if so, producing an output block in which the order of data and control blocks is preserved by deleting a set of bits from the block-type field of at least one control block, adding to the sequence an N-bit position indicator indicating positions of data and control blocks in the sequence, and providing in bit positions of remaining bits of the block-type field of the at least one control block an indication of the type of that control block; wherein the position indicator bits are added at bit-positions such that, in a header-first transmission order of the output block, all data and control blocks succeed the position indicator bits indicating positions of those blocks.

1. A data encoding method for encoding a sequence of N input blocks of bits into an output block for transmission, wherein each input block comprises one of a data block and a control block, the control block being one of K types of control block and including a block-type field indicating the type of that control block, the method comprising:
adding an L-bit control indicator, indicating whether the sequence contains any control blocks, as a header to the sequence; and if the sequence contains any control blocks, producing the output block in which the order of data and control blocks in the sequence is preserved by deleting a set of bits from the block-type field of at least one control block, adding to the sequence an N-bit position indicator indicating positions of data and control blocks in the sequence, and providing in bit positions of remaining bits of the block-type field of the at least one control block an indication of the type of that control block; wherein the position indicator bits are added at bit-positions such that, in a header-first transmission order of the output block, all data and control blocks succeed the position indicator bits indicating positions of those blocks.
