Originator and recipient based transmissions in wireless communications

摘要

Methods and systems are described for determining a plurality of transmission levels for, e.g., a plurality of time-frequency channels and/or a plurality of tones. The transmission levels may be determined by a first node based on, for example, a received transmission from a second node. The first node may generate a signal, which may be based on, for example, an originator-based pseudorandom sequence, a recipient-based pseudorandom sequence, and/or a complex sinusoid. The first node may transmit the signal as an orthogonal frequency division multiplexing (OFDM) transmission.

1. A method comprising:
receiving, by a first node, a first transmission from a second node; determining, based at least in part on the first transmission, a plurality of transmission levels, respectively, for a plurality of time-frequency channels; generating a signal that comprises an originator-based first pseudorandom sequence; and transmitting the signal, via the plurality of time-frequency channels and using the plurality of transmission levels, as at least part of an orthogonal frequency division multiplexing (OFDM) second transmission via one or more antennas of a plurality of antennas of the first node.
