Abstract
A method of signalling resource allocation data in a communication system which uses a plurality of sub-carriers arranged in a sequence of chunks. An allocation of the sub-carriers for each of a plurality of user devices is received. The received allocations are processed to determine, for each user device, data identifying a start chunk and an end chunk within the sequence of chunks, which depend upon the sub-carriers allocated to the user device. Different resource allocation data is generated for each of the user devices using the data identifying the corresponding start chunk and end chunk determined by the processing. The respective resource allocation data is signaled to each of the plurality of user devices.
Claims21
A method of signalling 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;
- processing the received allocations to determine, for each user device, data identifying a start chunk and an end chunk within said sequence of chunks, which depend upon the subcarriers allocated to the user device;
- generating different resource allocation data for each of said user devices using said data identifying the corresponding start chunk and end chunk determined by said processing;
- and
- signalling the respective resource allocation data to each of said plurality of user devices.
A method performed by a user device for determining carrier frequency allocation in a communication system which uses a plurality of sub-carriers arranged in a sequence of chunks, the method comprising:
- receiving signals from a communications node, which signals include different resource allocation data for each of a plurality of user devices;
- identifying the resource allocation data for the user device performing the method, which resource allocation data identifies a start chunk and an end chunk within said sequence of chunks;
- holding information which relates resource allocation data to said sequence of chunks of sub-carriers;
- and
- determining the allocated sub-carriers using the received resource allocation data and said held information.
A communication node which is operable to communicate with a plurality of user devices using a plurality of sub-carriers arranged in a sequence of chunks, the communications node comprising:
- a receiver operable to receive an allocation of said sub-carriers for each of a plurality of user devices;
- a processor operable to process the received allocations 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;
- a generator operable to generate respective resource allocation data for each of said user devices using said data identifying the corresponding start chunk and end chunk determined by said processor;
- and
- an output operable to output said respective resource allocation data to each of said plurality of user devices.
A user device which is operable to communicate with a communication node which is operable to communicate with a plurality of user devices using a plurality of subcarriers arranged in a sequence of chunks, the user device comprising:
- a receiver operable to receive signals from the communications node, which signals include different resource allocation data for each of the plurality of user devices;
- a controller operable to identify the resource allocation data for the user device, which resource allocation data identifies a start chunk and an end chunk within said sequence of chunks;
- a memory or circuit operable to hold information relating said resource allocation data to said sequence of chunks;
- and
- a determiner operable to determine the allocated sub-carriers using the received resource allocation data and said held information.
