摘要： Methods, systems, and apparatuses are described for wireless communications. More particularly, an access point (AP) identifies a plurality of multi-user multiple-input multiple-output (MU-MIMO) groups associated with a wireless station (STA). The AP determines a communication metric associated with each of the plurality of MU-MIMO groups. The communication metric provides an indication of the compatibility of the STAs in the MU-MIMO group. The AP prioritizes at least one of the plurality of MU-MIMO groups based at least in part on the communication metric associated with the prioritized MU-MIMO group. The AP creates a preferred group list and/or a blacklisted group list and included the prioritized MU-MIMO group in the appropriate group list.

摘要： 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.

摘要： Transmission power of a signal may be lowered in response to detecting a broadcast radio transmission. A communication device may communicate via a powerline communication (PLC) medium by transmitting, via the PLC medium, a signal having at least a first carrier frequency. The communication device may detect a broadcast radio transmission. The communication device may lower a transmission power setting associated with the first carrier frequency from a first power level to a second power level that is lower than the first power level in response to detecting the broadcast radio transmission. The communication device may transmit, via the PLC medium, the signal having at least the first carrier frequency at the second power level during a time period associated with the broadcast radio transmission.

摘要： A first Signal-to-Noise Ratio (SNR) average is determined for a first symbol set of at least one or more first symbols in one or more packets. A second SNR average is determined for a second symbol set of at least one or more second symbols in the one or more packets. A first difference between the first SNR average and the second SNR average is determined. In response to determining that the first difference exceeds an SNR threshold, a determination is made whether a first channel event has occurred in the one or more packets at least within the first symbol set and the second symbol set. In response to determining that the first channel event has occurred, a determination is made whether to remain at the first data rate or at a second data rate that is higher than the first data rate.

摘要： Methods, systems, and devices are described for wireless communication. In one aspect, a method of wireless communication includes receiving, by a first wireless device (AP), compressed beamforming information from each of a plurality of stations (STA-1...STA-n), the compressed beamforming information including a feedback signal-to-noise ratio (SNR) value and compressed feedback matrix. The method also includes determining a multi-user signal-to-interference-plus noise ratio (SINR) metric for each of the plurality of stations based at least in part on the received feedback SNR values and the received compressed feedback matrices.

摘要： A response interframe space (RIFS) time period may be adapted in a communication system. The RIFS time period may be determined based, at least in part, on a processing time used by a receiving device to process a received physical layer transmission from a transmitting device. The RIFS may be optimized in consideration of channel conditions for a particular communications channel, capabilities of a receiving device, and/or characteristics of a particular physical layer transmission. For example, the RIFS may be dependent on characteristics of a final transmission symbol used to transmit a physical layer transmission. The RIFS may depend on a processing time associated with decoding forward error correction (FEC) encoded blocks that end in the final transmission symbol. The RIFS may depend on a quantity of decoding iterations in a communication system that uses iterative decoding of FEC encoded blocks.

摘要： 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.
