A method comprising: transmitting, by a network node (210, 220) within a wireless network to a reference node, a first precoded tracking signal based on estimated precoding weights that are estimated to provide a predetermined signal at the reference node; receiving, by the network node (210, 220) from the reference node, a message including information related to whether or not the predetermined signal was received at the reference node based, at least in part, on the first precoded tracking signal transmitted by the network node; and if the predetermined signal was not received at the reference node, then adjusting one or more transmission parameters of the network node (210, 220) that are estimated to more accurately provide the predetermined signal at the reference node, and transmitting, by the network node, a second precoded tracking signal based on adjusted transmission parameters; wherein the predetermined signal is a signal provided at the reference node based on a cooperative joint transmission of precoded signals from a plurality of network nodes, including the transmission of the first precoded signal from the network node (210, 220) and a transmission of another precoded signal from at least one other network node; and wherein the receiving, by the network node (210, 220) from the reference node, a message including information related to whether or not the predetermined signal was received at the reference node comprises receiving, by the network node, a difference between corresponding signal parameters of strongest multipath components of the plurality of network nodes. transmitting, by a network node (210, 220) within a wireless network to a reference node, a first precoded tracking signal based on estimated precoding weights that are estimated to provide a predetermined signal at the reference node; receiving, by the network node (210, 220) from the reference node, a message including information related to whether or not the predetermined signal was received at the reference node based, at least in part, on the first precoded tracking signal transmitted by the network node; and if the predetermined signal was not received at the reference node, then adjusting one or more transmission parameters of the network node (210, 220) that are estimated to more accurately provide the predetermined signal at the reference node, and transmitting, by the network node, a second precoded tracking signal based on adjusted transmission parameters; wherein the predetermined signal is a signal provided at the reference node based on a cooperative joint transmission of precoded signals from a plurality of network nodes, including the transmission of the first precoded signal from the network node (210, 220) and a transmission of another precoded signal from at least one other network node; and wherein the receiving, by the network node (210, 220) from the reference node, a message including information related to whether or not the predetermined signal was received at the reference node comprises receiving, by the network node, a difference between corresponding signal parameters of strongest multipath components of the plurality of network nodes.
