Abstract: A transmission frame is communicated to cause a media idle measurement period on a contention based communication media. The media idle measurement period (i.e., “quiet period”) provides a period of inactivity on the communications medium that may be used to detect for the presence of foreign signals such as radio broadcast interference, noise, or other signals, or may be used for calibration of circuitry coupled to the communications medium. Idle measurement periods may be caused regularly (e.g., periodically). The transmission frame may include an explicit instruction for the media idle measurement period or may cause the media idle measurement period by simulating a collision on the communications media.

Abstract: A power spectral density (PSD) shape may be modified based upon the transmitter power setting of a transmitter. The power associated with notched frequencies and adjacent frequencies may be adjusted responsive to a change in transmitter power setting. As a result of adjusting the power for the notched frequencies and adjacent frequencies when operating at the different transmitter power setting, the performance of the transmission system is improved. The PSD shape may be considered dynamic, being modified responsive to a change in transmitter power setting by adjusting power associated with notches in the PSD shape based on the transmitter power setting and PSD constraint.

Abstract: This disclosure provides several mechanisms for adapting transmit power spectral density (PSD). A communications device may adapt the power spectrum utilized at the transmitter based, at least in part, on the channel conditions or PSD constraints associated with the communications medium between the transmitter and a receiver device. Additionally, the transmit PSD may be adapted based, at least in part, on a total power capability associated with a transmitter. Power is allocated to improve throughput and utilization of the communications channel. A transmission profile may be selected based, at least in part, on the notch depth. The transmission profile may be associated with symbol timing parameters. The communications device may maintain a plurality of selectable pulse shapes that are optimized for different notch depths.

Abstract: A first network device detects at least a first orthogonal code included in a preamble of a network packet received at the first network device from a second network device in an orthogonal frequency division multiplexing (OFDM) communication network. The first network device determines whether the first orthogonal code included in the preamble is associated with an assigned orthogonal code for the first network device. The assigned orthogonal code for the first network device is orthogonal to other assigned orthogonal codes for other network devices in the OFDM communication network. An operational mode of the first network device is changed from a sleep mode to an awake mode in response to determining the first orthogonal code is associated with the assigned orthogonal code for the first network device.

Abstract: A tone map includes physical layer transmission properties for a multi-carrier communications channel. The physical layer transmission properties indicate modulation mode and transmission power to be used on one or more frequencies (i.e. “tones”). The transmission power may be reduced on a first frequency having a high signal-to-noise ratio (SNR) so that performance will improve for a second frequency having a lower SNR. Transmission power may be reduced on a first frequency having an unusably low SNR so that performance will improve on a second frequency. A tone map message is used to efficiently communicate modulation and transmission power adjustments on a per-carrier basis.
