Abstract
Methods, systems, and devices are described for wireless communication. An access point (AP) may determine a single user bias for a wireless device based on a feedback signal-to-noise ratio (SNR) and an SNR based on a modulation and coding scheme (MCS). The AP may also determine a multi-user SNR for the wireless device based on the feedback SNR, the single user bias, a multi user loss, and a group bias. The AP may then select an updated MCS based on the multi-user SNR. In some cases, the AP may transmit a reference signal to the wireless device and receive a compressed beamforming feedback report from the wireless device based on the reference signal. The feedback SNR may be based on the compressed beamforming feedback report. The AP may also maintain a blacklist of groups with channel correlation that satisfies a threshold, and refrain from scheduling those groups together.
