摘要:
Methods and systems are described for orthogonal frequency division multiplexing (OFDM) transmission of data associated with multiple nodes and/or users. A plurality of weights may be determined based on, for example, feedback from one or more nodes. The feedback from each node may be indicative of weighting information. A multiple-input multiple-output (MIMO)-capable node may transmit OFDM transmissions, which may be time and frequency coincident, using the plurality of weights. For example, the MIMO-capable node may transmit a first OFDM transmission using at least a first weight of the plurality of weights and a second OFDM transmission using at least a second weight of the plurality of weights. This may allow the MIMO-capable node to, for example, transmit OFDM transmissions to multiple users via one or more common time-frequency channels.
