1. An apparatus for determining a position of an entity of a wireless communication network, the apparatus being implemented as a microprocessor, the apparatus comprising:
a position determining processor configured to determine a position of a first entity of the wireless communication network using information about a set of measurements between the first entity and one or more second entities, wherein the first entity is a user equipment, and wherein the one or more second entities are one or more transmission reception points (TRPs), and
wherein, for each measurement of the set of measurements between the first entity and one of the second entities, said one of the second entities uses a respective antenna pattern for transmitting a reference signal for the measurement on a respective positioning reference signal (PRS) resource of a PRS resource set, the PRS resource set being indicative of a plurality of PRS resources associated with respective resource identifiers, and
wherein, in performing the set of measurements, the first entity uses an antenna pattern with an antenna pattern identifier for performing reference signal received power (RSRP) measurements and/or timing measurements on the PRS resources of the PRS resource set,
wherein the antenna pattern used by the first entity for the set of measurements and the respective antenna pattern used by said one of the second entities for transmitting the reference signal for the measurement are specific to an operation of antennas of the first entity and said one of the second entities using respective spatial filters for transmitting or receiving the reference signal,
wherein the information about the measurement comprises antenna pattern information about each of the antenna patterns used by said one of the second entities for the set of measurements, wherein the measurement information indicates, for each of the antenna patterns used by said one of the second entities for the set of measurements, a resource identifier associated with the PRS resource used for the respective measurement, and wherein the antenna pattern information comprises, for each of the antenna patterns, information about a steering direction towards which the antenna pattern is directed, and further comprising information about a gain of the antenna pattern towards one or more predetermined directions, and
wherein the first entity is configured for being provided with a configuration information for the set of measurements, the configuration information indicating a configuration of the PRS resources,
wherein the position determining processor is configured to use, in determining the position of the first entity, the assumption that the first entity uses the same antenna pattern to measure the plurality of PRS resources of the PRS resource set.
