Claim 0:
1. A network node configured to communicate with a wireless device (WD), the network node comprising:
at least one processor; and
memory storing software instructions configured to control the at least one processor to implement a process including:
employing a coordinated multipoint process to decode data from a WD using signals received from the WD by the network node and from signals received from the WD by a plurality of cooperating network nodes;
converting the decoded WD data into a time domain reference signal and convert the signals received from the plurality of cooperating network nodes into time domain neighbor signals;
cross-correlating the time domain reference signal with the time domain neighbor signals to determine a time difference of arrival for each of the plurality of time domain neighbor signals; and
calculating a position of the WD based on the time differences of arrival and based on locations of the cooperating network nodes.
