Allocation of orthogonal resources to user equipment

A method performed at a network control node of allocating a set of orthogonal resources to user equipment within a network for transmitting signals to serving network nodes, said method comprising:

• providing network nodes within said network with one of at least two designations such that at least some network nodes have a same designation and at least some adjacent network nodes adjacent to said some network nodes have different designations;
• for said plurality of network nodes of a same designation indicating to said network nodes a subset of said set of orthogonal resources that are available to be allocated by a respective one of said network nodes to edge user equipment that are located towards a respective edge of a respective cell of radio coverage provided by said respective network node, only resources of said set of orthogonal resource that are not allocated to said edge user equipment being available to be allocated by said respective network node to centre user equipment that are located towards a centre of the cell of radio coverage provide by said respective network node;
• wherein
• respective network nodes of different respective designations receive indications of different respective subsets of said set of orthogonal resources, no resources from said set of orthogonal resources being within more than one subset and wherein resources available for allocation to centre user equipment of a respective network node include resources allocated to edge user equipment by network nodes of a different designation from that of the respective network node.
