Abstract
Efficient encoding techniques are described for encoding resource allocation data to be signalled to a user device. In one encoding technique one or more frequency blocks are assigned to a user device and a plurality of resource blocks within the assigned frequency blocks are allocated to the user device. The assignment of frequency blocks and the resource block allocation are encoded separately and signalled to the user device. On receipt of the signalled information the user device interprets the frequency block assignment and uses this when interpreting the resource block allocation.
