Abstract
Methods and systems are described for transmitting data to a node using a plurality of radio frequency channels. The data may be allocated, based on feedback from the node, into various portions amongst multiple radio frequency channels and/or amongst tones associated with the radio frequency channels. The data portions may be transmitted to the node, using frequency diversity, via respective radio frequency channels as at least part of respective orthogonal frequency division multiplexing (OFDM) transmissions, which may be at least partially concurrent transmissions.
