1. A method of resource scheduling in a wireless communication network, the network comprising N neighbouring cells indexed by i which share the same frequency band, where i=0, . . . , N?1, and N>=3, the method comprising:dividing the available frequency resources of the frequency band into N subsets indexed by j, where j=0, . . . , N?1, wherein the frequency resources in each of the subsets are not consecutive and wherein each available frequency resource is assigned to only one of the N subsets; and

for each downlink subframe of a frame, allocating each of the N subsets to a respective one of the N cells, such that each available frequency resource is allocated to only one of the N cells, for the downlink subframe,

wherein Physical Cell ID (PCI) values of the N cells mod N are equal to 0, 1, . . . , N?1 respectively, and

wherein said allocating the N subsets comprises obtaining the index j of the subset to be allocated to the ith cell in the kth downlink subframe by j=(PCI value of the ith cell+k) mod N.

for each downlink subframe of a frame, allocating each of the N subsets to a respective one of the N cells, such that each available frequency resource is allocated to only one of the N cells, for the downlink subframe,

wherein Physical Cell ID (PCI) values of the N cells mod N are equal to 0, 1, . . . , N?1 respectively, and

wherein said allocating the N subsets comprises obtaining the index j of the subset to be allocated to the ith cell in the kth downlink subframe by j=(PCI value of the ith cell+k) mod N.
