Abstract: A wireless device including a first receiver and a second receiver. The first receiver is configured to receive a first signal transmitted on a first network using a first communication standard, and generate, in response to a signal strength of the first signal being greater than or equal to a predetermined threshold, first information about the first signal based on a first portion of the first signal. The second receiver is configured to receive a second signal transmitted on a second network using a second communication standard, and suppress interference from the first signal based on the first information about the first signal. The first communication standard is different from the second communication standard. The first receiver and the second receiver are co-located in the wireless device.

Abstract: A method for communicating in a wireless local area network is disclosed herein. The AP sets an uplink target received signal strength information (RSSI) for all participating stations (STAs) and transmits the information to the STAs in a trigger frame. Specifically, the AP sets the uplink target RSSIs for each STA to be within a predetermined range of each other so that when the STAs transmit respective uplink frames, those frames are received at the AP at the set uplink target RSSI.

Abstract: The present disclosure includes systems and techniques relating to an integer non-uniform constellation (NUC) high-order M-QAM. In some implementations, a scale factor is identified for a mapping of bit patterns into M constellation points of a NUC M-QAM, wherein M is no less than 1024; each of the M constellation points has respective real and imaginary coordinates; and the respective real and imaginary coordinates having respective decimal parts that are integer multiples of 2−n, with n being a non-negative integer less than 5. A bit pattern is received and mapped to integer real and imaginary coordinates of one of the M constellation points according to a mapping rule of the NUC M-QAM. The integer real and imaginary coordinates of the one of the M constellation points equal the scale factor multiplied with respective real and imaginary coordinates of the one of the M constellation points having respective decimal parts.
