A method and network node for uplink coordinated multipoint positioning are disclosed. According to one aspect, a method includes employing a coordinated multipoint function 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. The method further includes converting the decoded WD data signal into a time domain reference signal and convert the signals received from the plurality of cooperating network nodes into time domain neighbour signals. The method also includes cross-correlating the time domain reference signal with the time domain neighbour signals to determine a time difference of arrival for each of the plurality of time domain neighbour signals. The method also includes calculating a position of the WD based on the time differences of arrival and based on locations of the cooperating network nodes.

A method and network node for differential matched summed antenna positioning are disclosed. According to one aspect, a method includes summing sequential uplink data signals at each of a plurality of antennas of the network node to produce a plurality of antenna signal sums. The method also includes selecting one of the antenna signal sums to be used as a reference antenna signal sum. A channel impulse response is determined for each of a plurality of other antennas by cross correlating the reference antenna signal sum with the others of the plurality of antenna signal sums. The method further includes estimating a time difference of arrival from the channel impulse responses of the plurality of antennas, and estimating an error of the estimated time difference of arrival of each antenna. A position of a wireless device is determined using the estimated time differences of arrival.
