Abstract:
1. A method of allocating resources in a communication system which uses a plurality of sub-carriers arranged in a sequence of physical resource blocks wherein adjacent blocks of said sequence are arranged in groups, the method comprising, in a base station: determining at least one virtual resource block for allocation to a mobile communications device; signalling data identifying each virtual resource block to said mobile communications device; and mapping each allocated virtual resource block, using predetermined mapping data, onto a plurality of spaced physical resource blocks to determine the physical resource blocks to be used for communications with the mobile communications device; wherein said predetermined mapping data is such that said mapping causes the spacing between the mapped physical resource blocks to be an integer multiple of the square of the number of physical resource blocks in each group, wherein said signalled data represents a physical resource block to be used for a first part of a sub-frame, wherein at least part of said predetermined mapping data defines an equation for the location of a further physical resource block to be used for a further part of the sub-frame, and wherein the equation from which can be derived the location of a further physical resource block can be represented as follows: where I
