Abstract:
1. A method of signaling resource allocation data in a communication system which uses a plurality of sub-carriers arranged in a sequence of chunks, the method comprising: receiving an allocation of said sub-carriers for each of a plurality of user devices, which said received data identifies a type of allocation of said sub-carriers; processing the received allocations, in dependence on the identified type of allocation, to determine, for each user device, data identifying a start chunk and an end chunk within said sequence of chunks, which depend upon the sub-carriers allocated to the user device, wherein the data identifying the start chunk and the end chunk comprises a start chunk number and a number of consecutive chunks between the start chunk and the end chunk; generating different resource allocation data for each of said user devices using said data identifying a corresponding start chunk and end chunk determined by said processing, wherein said resource allocation data comprises a unique value representing the corresponding start chunk number, and the number of consecutive chunks between the corresponding start chunk and the corresponding end chunk, and wherein said resource allocation data comprises type data identifying the type of allocation and a bit pattern which defines a grouping of the sequence of chunks into a sequence of groups, in dependence upon the sub-carriers allocated to each user device; and signaling the respective resource allocation data, comprising said unique value and said type data, to each of said plurality of user devices; wherein in one of said types of allocation a user device is allocated a set of consecutive chunks of sub-carriers, and wherein said unique value x is given by at least one of: where N is a number of chunks in said sequence, O is the start chunk, and P is the number of consecutive chunks.
