Methods and apparatuses for positioning in a wireless communications network

A measuring device configured to communicate with a positioning device, the measuring device comprising a processor and a memory containing instructions executable by the processor whereby the measuring device is operative to:

• determine a cross-correlation between a received signal and a transmitted reference signal;
• determine a channel impulse response (CIR) of the cross-correlation, related to a first lobe detected above a selected threshold in said CIR;
• and
• report a truncated part of the CIR around the first lobe to the positioning device for enabling the positioning device to correct or estimate a measurement related to a distance between a transmitter and the measuring device and/or a distance between at least one reflecting cluster and the measuring device, wherein the first lobe includes a first arrival path, and the truncated part of the CIR includes a selected number of samples around the first arrival path included in the first lobe in the CIR.

A method performed by a positioning device configured to communicate with a measuring device, the method comprising:

• configuring the measuring device to determine a cross-correlation between a received signal received by the measuring device and a transmitted reference signal;
• configuring the measuring device to determine a channel impulse response (CIR) of the cross-correlation, related to a first lobe detected above a selected threshold in said CIR;
• receiving from the measuring device a report including a truncated part of the CIR around the first lobe, wherein the first lobe includes a first arrival path, and the truncated part of the CIR includes a selected number of samples around the first arrival path included in the first lobe in the CIR;
• and
• correcting or estimating a measurement related to a distance between a transmitter and the measuring device and/or a distance between at least one reflecting cluster and the measuring device.
