Abstract:
1. A method for sub-channelization or structuring a range of OFDMA subcarriers for allocation to mobile users in a telecommunication system, wherein the OFDMA subcarriers are arranged into a plurality of subcarrier blocks, each subcarrier block including as plurality of OFDMA subcarriers, the method comprising: within a network node serving the mobile users, at a first time point, allocating the subcarrier blocks among a plurality of subchannels, such that each subchannel is allocated to a corresponding one of the mobile users and includes a plurality of contiguous subcarriers blocks covering a range of frequencies; and within the network node, at each of a plurality of time points subsequent to the first time point, reallocating and interleaving the subcarrier blocks among the subchannels, each reallocation increasing the range of frequencies allocated to each subchannel over the range of frequencies allocated to the subchannel at the immediately previous time point.
