Abstract: Various embodiments herein disclose scheduling relay of traffic. The method comprises, selecting a second client device from a plurality of client devices. The second client device is located in communication range of the first client device. The first client device is communicating a first portion of a data flow, via a first wireless link, with a first access point of the one or more access points. The method comprises, in response to determining satisfaction of one or more relay criteria: directing the first access point to generate a second wireless link with the second client device; and directing the first access point to provide first metadata including a first set of relay instructions. The first set of relay instructions instructs the second client device to relay a second portion of the data flow between the first access point and the first client device via the second wireless link.

Abstract: Multi-User Multiple Input, Multiple Output (MU-MIMO) data transmissions are provided with a forward-predictive precoding matrix to mitigate the effects of a change in a state of a communication channel. First and second soundings are performed, at first and second times, to a receive antenna over a channel and, responsive to each of the soundings, first and second Channel State Information (CSI) are received. Based on the first and second CSI, a change in a state of the channel over a time period between the first and second time is determined. Based on the change in the state of the channel, a forward-predictive channel state matrix and/or a forward-predictive precoding matrix are determined that reflect a state of the channel at a future time and that are consistent with the determined change in the state over the time period. The forward-predictive precoding matrix is applied to a data transmission.
