ADVANCED DATA CELL RESOURCE MAPPING

摘要

An example method of mapping a plurality of modulation symbols of a plurality of physical layer pipes present in a frame to a resource grid of data cells for the frame is described. The modulation symbols of the plurality of physical layer pipes are represented by a two-dimensional array comprising the modulation symbol values for the plurality of physical layer pipes and the resource grid of data cells is represented by a one-dimensional sequentially indexed array.

1. A method of mapping a plurality of modulation symbols of a plurality of physical layer pipes present in a frame to a resource grid of data cells for the frame, wherein the modulation symbols of the plurality of physical layer pipes are represented by a two-dimensional array comprising the modulation symbol values for the plurality of physical layer pipes and wherein the resource grid of data cells is represented by a one-dimensional sequentially indexed array, the method comprising the steps of:
determining whether a current physical layer pipe of the plurality of physical layer pipes is dispersed or non-dispersed; responsive to determining that the current physical layer pipe is non-dispersed, populating a next available position of the one-dimensional array with a first modulation symbol value of the current physical layer pipe from the two-dimensional array, wherein the step is repeated for all modulation symbol values of the current physical layer pipe; and responsive to determining that the current physical layer pipe is dispersed:
calculating a sub-slice size for the current physical layer pipe by dividing the size of the physical layer pipe with the number of sub-slices in the current physical layer pipe; andpopulating a next available position of the one-dimensional array with a first modulation symbol value of a current sub-slice of the current physical layer pipe from the two-dimensional array, wherein the step is repeated for all modulation symbol values of the current sub-slice and for all sub-slices of the current physical layer pipe; wherein the steps of the method are repeated for all of the plurality of physical layer pipes in the present frame.
