Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for the scheduling of wireless resources to multiple wireless stations participating in a simultaneous transmission. Some implementations more specifically relate to the allocation of resource units (RUs) to stations for an uplink multi-user OFDMA (UL MU-OFDMA) transmission. In some implementations, an access point (AP) may adjust a modulation and coding scheme (MCS) of one of the stations based on the results of a power imbalance check. For example, in response to determining that a station failed the power imbalance check, the AP may reduce the MCS assigned to the station from a current value to a reduced value as opposed to simply dropping the station from the scheduled transmission. In some implementations, the AP then performs another power imbalance check based on the reduced MCS. The process may be repeated in an effort to provide all of the grouped stations the opportunity to successfully participate in the UL MU-OFDMA transmission.

Abstract: A method and apparatus are disclosed for searching for a radar signal within signals received by a wireless device. The wireless device may receive signals within a first frequency segment and a second frequency segment, which is adjacent to the first frequency segment. The wireless device may determine Fast Fourier Transform (FFT) bins associated with the first frequency segment and the second frequency segment. The wireless device may combine the FFT bins associated with the first frequency segment and the second frequency segment and may search for the radar signal within the combined FFT bins.
