Abstract:
According to an example embodiment, a method may include determining, by a first wireless node in a wireless network, a number N of resource blocks available for transmitting data within a cell, the N resource blocks each including V resource block orthogonal frequency division multiplexing (OFDM) symbols, the V resource block OFDM symbols each including U resource block subcarriers. The method may also include mapping the N resource blocks into N subchannels based on a permutation formula, the permutation formula assigning, based on permutation parameters including the number N and a random or pseudorandom variable, U subchannel subcarriers for each of V subchannel OFDM symbols to each of the N subchannels and thereby allocating a subchannel index for each of the N subchannels. The method may also include sending a message to a second wireless node indicating the permutation parameters and the allocated subchannel index of at least one of the N subchannels for communication between the first wireless node and the second wireless node.
