1. A method comprising:
- receiving, by a multiple-input multiple-output (MIMO)-capable third node, a transmission from a first node and a transmission from a second node;
determining a first plurality of weights based at least in part on the transmission from the first node and a second plurality of weights based at least in part on the transmission from the second node; and
transmitting, via one or more antennas of a plurality of antennas, an orthogonal frequency division multiplexing (OFDM) symbol that comprises;
first data, associated with the first node, weighted in first one or more time-frequency channels using at least one of the first plurality of weights; and
second data, associated with the second node, weighted in second one or more time-frequency channels using at least one of the second plurality of weights.

Abstract
Methods and systems are described for determining and transmitting at least one orthogonal frequency division multiplexing (OFDM) symbol that may comprise data associated with multiple nodes such as a first node and a second node. Each OFDM symbol may be determined using weights, time-frequency channels, and/or tones that are determined based at least in part on transmissions from the first node and the second node.
