CPC H04B 7/0617 (2013.01) [G01S 5/0036 (2013.01); H04B 7/0619 (2013.01); H04B 7/0695 (2013.01); H04W 64/00 (2013.01)] | 1 Claim |
1. An apparatus comprising:
at least one processor, and
at least one memory including a computer program code, wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus to:
receive, from a location management function, information regarding a number of antennas and/or an oversampling factor;
transmit, by the apparatus, a plurality of beams in accordance with the information received regarding the number of antennas and the oversampling factor;
receive measurement results regarding the plurality of beams from another apparatus, wherein the measurement results include: a reference signal received power value (RSRP), a beam identifier, a value indicating uncertainty of an accuracy of the reference signal received power value, a beamforming gain, and a signal-to-noise ratio measured on a positioning reference signal received by the other apparatus, wherein in the RSRP is in the form of a variance σi2, which is calculated by a terminal device as a function of a received SNR and a number of resource elements (RE) over which the RSRP is averaged;
process the received measurement results to obtain information regarding a position of the other apparatus using a Gauss-Newton procedure;
determine an angle of departure (AoD) based on the processed measurement results; and
provide the obtained information regarding the position of the other apparatus and the AoD to the location management function,
wherein the apparatus is or is comprised in the access node or a gNodeB.
