Patent ID: 8111609

Claim:
A method comprising: 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 a number V of resource block orthogonal frequency division multiplexing (OFDM) symbols, the V resource block OFDM symbols each including a number U of resource block subcarriers; 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, a random or pseudorandom variable, and an identifier of the cell, 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; and sending a message to a second wireless node indicating the permutation parameters N and the random or pseudorandom variable, 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.
