Aspects for machine learning-based link adaptation are described. For example, an apparatus can determine k-nearest neighbors (K-NNs) based on training data associated with the sub-band and on the signal to interference and noise ratio (SINR) of the sub-band. In aspects, the apparatus can identify a channel quality indicator (CQI) associated with the lowest error rate for the k-NNs and provide the identified CQI to a base station. In aspects, a neural network (NN) can provide labels for CQIs that indicate probability of choosing a CQI, and the CQI having highest probability will be provided to a base station. In aspects, a covariance matrix based on samples of a communication channel can be provided to a NN to determine a rank indicator (RI) corresponding to the channel, and channel state information associated with the (RI) can be sent to the base station. Other aspects are described.

This disclosure describes methods, apparatus, and systems related to a high efficiency signal field encoding structure. A device may determine a communications channel having a bandwidth of a frequency band. The device may determine a first group of subchannels of the bandwidth and a second group of subchannels of the bandwidth. The device may determine a high efficiency signal field to be transmitted on the communications channel to a first device. The device may encode the high efficiency signal field using the first group of subchannels and the second group of subchannels.

High efficiency signal field encoding structure

A transmitter/receiver pair may estimate a first channel interference caused during the spatial reuse phase by the transmitter/receiver pair to other transmitter/receiver pairs over a channel. A second channel interference experienced by the transmitter/receiver pair may be estimated during the spatial reuse phase by the transmitter/receiver pair from the other transmitter/receiver pairs. An interference margin may be estimated for the channel based on the first and second channel interferences. The interference margin may be announced to the other transmitter/receiver pairs in frame. The interference margin may then be complied with while communicating over the channel in order to control the interference.
