Resource allocation

摘要

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 a predetermined mapping which relates the data identifying the corresponding start chunk and end chunk determined by the processing step to resource allocation data comprising a unique value. The respective resource allocation data is signaled to each of the plurality of user devices.

主权项

1. A communication node, comprising:
a generator configured to generate control information which includes a first bit pattern and resource allocation information, wherein the first bit pattern shows a type of resource allocation that identifies allocation of chunks which comprises subcarriers in a sub-frame, wherein the resource allocation information comprises a resource indication value that corresponds to a starting chunk and a length measured in consecutive chunks and that is defined by at least one of expressions:
N(P−1)+O, andN(N−(P−1))+(N−1−O), wherein N is a number of chunks in a pre-set bandwidth, O is the starting chink, and P is the length measured in consecutive chunks; and a transmitter configured to transmit the control information to at least one user equipment.
