FIELD: radio engineering, communication.
SUBSTANCE: invention relates to radio communication. The invention describes solutions for use of a combination of types of reference signals in a wireless communication network when making measurements relating to positioning. As per one example, UE uses a combination of CRS and PRS. As an illustrative case, UE receives PRS and possibly CRS from one or more honeycombs while it receives only CRS from one or more other honeycombs. In this case, UE determines for example time tag values of the received signal for CRS as those received from some honeycombs for each honeycomb and for PRS as those received from other honeycombs for each honeycomb. UE can make measurements and notify for each signal/for each honeycomb and can make calculations, in which a combination of time tag measurements participates, which have been made both for CRS and for PRS. In an additional aspect, control or coordination of transmissions of reference signals is performed for each port in honeycombs, which use multiple antenna ports to perform transmission in every such honeycomb.
EFFECT: improving positioning measurement quality.
