Enhanced multi-user transmission

Communication carried out over a frequency band divided into a plurality of subcarriers by messages transmitted between a first radio station and a second radio station in a plurality of hops between respectively adjacent radio stations arranged in hierarchical levels. A subset of the subcarriers is used for each hop. The subsets used are allocated by at least one higher level radio station and the composition of at least one of the subsets used varies over time.
