    Abstract: Aspects described herein include a method comprising predicting, based on one or more transmission characteristics, error values for a sequence of bit positions used for modulating data within a packet. The method further comprises generating a bitmap that maps one or more payload bits and one or more padding bits of the packet to respective bit positions of the sequence. The one or more padding bits are preferentially mapped to respective bit positions having relatively greater error values. The method further comprises modulating the sequence according to the bitmap.

    Abstract: The present disclosure provides for distortion cancelled by receiving a collided signal, the collided signal comprising a first signal carrying a first packet and a second signal carrying a second packet (110); amplifying and digitizing the collided signal into a first digital signal at a first gain (120) and a second digital signal at a second gain that is greater than the first gain (150); determining a nonlinear interference component of the first packet on the second packet from the first digital signal (140); decoding the first packet from the first digital signal (130); re-encoding the first packet with a first estimated channel effect into an estimated signal; calculating a linear interference component of the first packet on the second packet from the estimated signal (140); removing the linear interference component and the nonlinear interference component from the second digital signal to produce a de-interfered signal (160); and decoding the second packet from the de-interfered signal (170).

    Abstract: Bi-directional and full-duplex communication is provided by allocating Resource Units (RU) to Stations (STAs), wherein a first RU of a plurality of RUs in a Protocol Data Unit (PDU) is allocated to a first STA of a plurality of connected STAs as a bidirectional (BD) RU for full-duplex communications with the first STA; transmitting a generalized-trigger to the plurality of connected STAs to assign the plurality of RUs; transmitting downlink (DL) communications on DL RUs of the plurality RUs and the BD RU; and receiving uplink (UL) communications on UL RUs of the plurality of RUs and the BD RU. The UL RUs may be delayed by a predefined amount of time relative to the DL RUs of the plurality of RUs. In some embodiments, the BD RU Traffic is a reassigned RU scheduled for an opposite direction of communication in the PDU.

    Abstract: A first device having a plurality of antennas wirelessly transmits multiple series of test packets to a second device having one or more antennas, each series of test packets being transmitted with a different level of interference imposed on the test packets. The first device determines a packet error rate for each series of test packets transmitted by the first device. The first device derives an estimate of an interference cancellation capability of the second device based on the packet error rate for different levels of interference.

    Abstract: Techniques for peer-to-peer (P2P) transmission using interference alignment are disclosed. These techniques include calculating one or more precoder matrices and one more decoder matrices relating to interference alignment for data transmission between a plurality of wireless stations (STAs). The techniques further include initiating P2P transmission between the plurality of STAs using the one or more precoder matrices and the one or more decoder matrices, the P2P transmission including: simultaneously transmitting data between at least two pairs of STAs, of the plurality of STAs, using the one or more precoder matrices and the one or more decoder matrices for interference alignment of the simultaneous transmissions.
