1. A method to be executed by an infrastructure node, comprising: receiving one or more sounding signals transmitted to the infrastructure node from a remote station transmitting the sounding signals; exchanging timing information of the one or more sounding signals between the infrastructure node and one or more other infrastructure nodes; comparing phases or times of arrival, or combinations thereof, of the sounding signals on the infrastructure node and the one or more other infrastructure nodes; calculating phase adjustments or timing adjustments, or combinations thereof, to apply to spatial streams for the infrastructure node; and applying intra-node phase or timing adjustments, or inter-node phase or timing adjustments, or combinations thereof, during one or more transmissions from the infrastructure node to the remote station, wherein said applying comprises: calculating adjustments for a first group of subcarriers; extrapolating the calculated adjustments for a second group of subcarriers; and applying a phase adjustment or a timing adjustment, or combinations thereof, to the first group of subcarriers based on the calculated adjustments and to the second group of subcarriers based on the extrapolated adjustments according to a function of frequency, wherein the function is a linear function, a non-linear function, a filter function, or combinations thereof.
