1. A communications node which communicates with a communications device (3), the
communications node (5) comprising:
means for transmitting (21) control information comprising a resource indication value for
indicating a resource allocation, wherein the resource indication value is defined by at least one of
expressions:
N(P-l)+Oor
N(N-(P-1))+(N-1 O)

2. A communications node according to the claim 1, wherein the control information further comprises a bit pattern that indicates a type of the resource allocation indicated by said resource indication vaiue.
3. A communications node according to the claim 1, wherein the resource blocks comprise subcarriers in a sub-frame.
4. A communications device which communicates with a communications node (5), the communications device (3) comprising:
means for receiving (71), from the communications node (5), control information comprising a resource indication value for indicating a resource allocation, wherein the resource indication value is defined by at least one of expressions:
N(P-l)+Oor
N(N-(P-l))+(N-l-0) where N is a number of resource blocks in a bandwidth, O is a starting resource block number and P is a length in terms of number of consecutive resource blocks;
means for interpreting (91) the resource allocation based on the control information; and
means for decoding (91) downlink data using resources interpreted based on the control information.
5. A communications device which communicates with a communications node, the
communications device (3) comprising:
