14. A method, by a wireless communication device, for wireless communication with a plurality of far-end communication devices over a plurality of corresponding wireless channels, the method comprising:
receiving, from each of the far-end communication devices, a set of pilots over the corresponding wireless channel, each wireless channel including a first portion that is time-invariant and a second portion that is time-variant;
generating estimates of the first and second portions of each wireless channel based on the corresponding set of received pilots;
scheduling data transmissions to the plurality of far-end communication devices based on the first portions of the corresponding wireless channels; and
transmitting the data to at least one of the plurality of far-end communication devices based on channel state information obtained from the estimates of the first and second portions of a respective wireless channel.
