Abstract: A method and network node for relative positioning measurements of wireless device (WD) locations are disclosed. According to one aspect, a method includes phase-locking a plurality of antenna reference points (ARPs), using a synchronous clock, allowing an accuracy of spatial coordinate estimates to be reduced while increasing their precision. The method includes determining time difference of arrival values based at least in part on applying weights to signals received from antennas of a subset of the plurality of phase-locked ARPs to further increase a precision of the spatial coordinate estimates. The method also includes estimating the spatial coordinates by applying timing error corrections to the time difference of arrival values to increase accuracy of the spatial coordinate estimates while maintaining the precision of the spatial coordinate estimates above the second precision level.

Abstract: A technique for radio transmitting data is described. As to a method aspect of the technique data to be transmitted to a receiver is represented by at least two partial modulation symbols. Each of the at least two partial modulation symbols is associated to a different layer of the radio transmission to the receiver. A modulation symbol is generated by combining the at least two partial modulation symbols at different power levels according to the associated layer. The modulation symbol is transmitted to the receiver.

Abstract: 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.
