Abstract
A plurality of cells are combined into a macro cell. In a macro header of the macro cell a full numbering information of a first cell of the plurality of cells is stored. For further cells of the plurality of cells other than the first cell, a deviation information indicating a deviation of a numbering information of the respective further cell from the full numbering information of the first cell or one of the further cells is stored. In some embodiments, additionally the headers of the individual cells are incorporated in the macro header.
Claims26
A method for header compression using a macro cell builder component in a transmitter, comprising:
- assigning information to be transmitted to a plurality of cells using the macro cell builder component,
- assigning a numbering information to each cell of said plurality of cells using the macro cell builder component, and
- storing said numbering information in a header to be transmitted with said plurality of cells using the macro cell builder component, wherein said storing step comprises:
- storing a full numbering information of a first one of said plurality of cells in said header, and
- storing a deviation of said numbering information of another one of said plurality of cells from said full numbering information in said header, wherein the deviation indicates an offset of said numbering information of the another cell from the first cell.
A method for header decompression using a macro cell analyzer component in a receiver, said method comprising:
- providing a plurality of cells having a single header to the macro cell analyzer component,
- retrieving a full numbering information of a first one of said plurality of cells from said header using the macro cell analyzer component,
- retrieving deviation information representing a deviation of a numbering information of at least another one of said cells from said full numbering information from said header using the macro cell analyzer component, wherein the deviation indicates an offset of said numbering information of the another cell from the first cell, and
- reconstructing said numbering information of said another one of said plurality of cells from said full numbering information and said deviation information using the macro cell analyzer component.
An apparatus for header compression, comprising:
- a cell builder configured to assign information to be transmitted to a plurality of cells, and further configured to assign a numbering information to each cell of said plurality of cells, and to store said numbering information in a single header to be transmitted with said plurality of cells, wherein said numbering information comprises:
- a full numbering information of a first one of said plurality of cells in said single header, and a deviation of said numbering information of another one of said plurality of cells from said full numbering information in said at least one header, wherein the deviation indicates an offset of the numbering information of the another cell from the first cell.
An apparatus for header decompression, wherein a single header is associated with a plurality of cells, said apparatus comprising:
- a cell analyzer configured to retrieve a full numbering information of a first one of said plurality of cells from said single header, and further configured to retrieve deviation information representing a deviation of a numbering information of at least another one of said cells from said full numbering information from said first cell, and to reconstruct said numbering information of said another one of said plurality of cells from said full numbering information and said deviation information, wherein the deviation indicates an offset of said numbering information of the another cell from the first cell.
