Method and device for allocating, by a telecommunication device, at least a first and a second consecutive channel elements of a group of channel elements of a channel resource to a destination
First Claim
1. A method for allocating, by a telecommunication device, at least first and second channel elements of a group of channel elements of a channel resource to a destination, each channel element being a predefined subdivision of the channel resource, the method comprising, executed by the telecommunication device:
- selecting, for the first channel element, a first randomization function according to a position of the first channel element within the group of channel elements and according to the destination;
selecting, for the second channel element, a second randomization function according to a position of the second channel element within the group of channel elements and according to the destination;
processing data to be included in the first channel element by the first randomization function and processing data to be included in the first channel element by the second randomization function; and
transferring the data processed by the first randomization function by mapping the data processed by the first randomization function on the first channel element and the data processed by the second randomization function by mapping the data processed by the second randomization function on the second channel element in combination with other data processed by other randomization functions mapped on other channel elements of the channel resource.

Abstract
A method for allocating, by a telecommunication device, at least first and second channel elements of a group of channel elements of a channel resource to a destination. The telecommunication device: selects, for the first channel element, a first randomization function according to the position of the first channel element within the group of channel elements and according to the destination; selects, for the second channel element, a second randomization function according to the position of the second channel element within the group of channel elements and according to the destination; processes the data to be included in the first channel element by the first randomization function and processes the data to be included in the first channel element by the second randomization function; and transfers the processed data.

10. A method for determining if at least first and second channel elements of a group of channel elements of a channel resource are allocated to a destination by a first telecommunication device, each channel element being a predefined subdivision of the channel resource, the method comprising, executed by the destination:
-
receiving a group of channel elements on which received data are mapped; selecting, for the first channel element, a first randomization function according to the position of the first channel element in the group of channel elements; selecting, for the second channel element, a second randomization function according to the position of the second channel element in the group of channel elements;
processing the received data mapped on the first channel element by the first randomization function;
processing the received data mapped on the second channel element by the second randomization function;
determining, among the processed received data, at least two identical processed received data obtained from the received data mapped on at least two channel elements of a subset of the group of channel elements; and
deciding that the at least two channel elements of the subset of the group of channel elements are allocated to the destination if the at least two processed received data are identical. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
