Method of resource allocation in a communication system
First Claim

1. A method of resource allocation in a communication system, comprising:
- setting specific time and frequency chunks within a band to provide localized and distributed resources for each of localized and distributed users where the localized resources allocate contiguous groups of tones to a user and the distributed resources provide non-contiguous groups of tones to the user;
signalling resource allocation for each user in a chunk at a same frequency range as an allocated resource, or a subset of the frequency range of the allocated resource;
allocating the localized and distributed resources to a particular chunk determined by blind detection based on a signalling structure, where the signalling is located in a same band as allocated resources.

Abstract
Resources are allocated in a communication system by setting specific time and frequency chunks within a band to provide localized and distributed resources for each of localized and distributed users. The signalling of resource allocation for each user is in the chunk at the same frequency range as the frequency range of the allocated resource, or a subset of the frequency range of the allocated resource.

14. A method of decoding a downlink resource allocation which has been allocated by setting specific time and frequency chunks within a band to provide localized and distributed resources for each of localized and distributed users where the localized resources allocate contiguous groups of tones to a user and the distributed resources provide non-contiguous groups of tones to the user, comprising:
-
signalling resource allocation for each user in a chunk at a same frequency range as an allocated resource, or a subset of the frequency range of the allocated resource; and applying a Viterbi algorithm to generate predecessor tables and accumulated metrics, wherein generated tables and metrics for chunks or sub-chunks of a band are stored as partial tables and metrics, and wherein the resources are decoded by combining the stored partial tables and metrics relating to the chunks or sub-chunks. - View Dependent Claims (15, 16, 17)

18. A method of resource allocation in a communication system, comprising:
-
setting specific time and frequency chunks within a band to provide localized and distributed resources for each of localized and distributed users, where the localized resources allocate contiguous groups of tones to a user and the distributed resources provide non-contiguous groups of tones to the user; signalling resource allocation for each user in at least one chunk at a same frequency range as an allocated resource, or a subset of the frequency range of the allocated resource; allocating the localized and distributed resources to a particular chunk determined by blind detection based on a signalling structure, where the signalling is located in a same band as allocated resources; and allocating to users a sub-chunk within each chunk of a set of chunks allocated to distributed resources, with a number of sub-chunks determined by a total number of chunks allocated to distributed resources within a band.
