Description The present application relates to the field of wireless communication systems or networks, more specifically to enhancements or improvements regarding the signaling of a location or position of a user device communicating with one or more further user devices using a sidelink, SL. Embodiments of the present invention concern the signaling of a location or a position of a user device being a member a group of UEs communicating over the sidelink. Fig. 1 is a schematic representation of an example of a terrestrial wireless network 100 including, as is shown in Fig. 1(a), a core network 102 and one or more radio access networks RANi, RAN2, ...RANn. Fig. 1(b) is a schematic representation of an example of a radio access network RANn that may include one or more base stations gNBi to gNBs, each serving a specific area surrounding the base station schematically represented by respective cells 106i to 106s. The base stations are provided to serve users within a cell. The one or more base stations may serve users in licensed and/or unlicensed bands. The term base station, BS, refers to a gNB in 5G networks, an eNB in UMTS/LTE/LTE-A/ LTE-A Pro, or just a BS in other mobile communication standards. A user may be a stationary device or a mobile device. The wireless communication system may also be accessed by mobile or stationary loT devices which connect to a base station or to a user. The mobile devices or the loT devices may include physical devices, ground based vehicles, such as robots or cars, aerial vehicles, such as manned or unmanned aerial vehicles (UAVs), the latter also referred to as drones, buildings and other items or devices having embedded therein electronics, software, sensors, actuators, or the like as well as network connectivity that enables these devices to collect and exchange data across an existing network infrastructure. Fig. 1(b) shows an exemplary view of five cells, however, the RANn may include more or less such cells, and RANn may also include only one base station. Fig. 1(b) shows two users UEi and UE2, also referred to as user equipment, UE, that are in cell 1062 and that are served by base station gNB2. Another user UE3 is shown in cell IO64 which is served by base station gNB4. The arrows IO81, 1082 and 1083 schematically represent uplink/downlink connections for transmitting data from a user UEi, UE2 and UE3 to the base stations gNB2, gNB4 or for transmitting data from the base stations gNB2, gNB4 to the users UEi, UE2, UE3. This may be realized on licensed bands or on unlicensed bands. Further, Fig. 1(b) shows two loT devices 110i and 1102 in cell 1064, which may be stationary or mobile devices. The loT device 110i accesses the wireless communication system via the base station gNB4 to receive and transmit data as schematically represented by arrow 112i. The loT device HO2 accesses the wireless communication system via the user UE3 as is schematically represented by arrow 1122. The respective base station gNBi to gNBs may be connected to the core network 102, e.g. via the S1 interface, via respective backhaul links 114i to 1145, which are schematically represented in Fig. 1(b) by the arrows pointing to “core”. The core network 102 may be connected to one or more external networks. Further, some or all of the respective base station gNBi to gNBs may be connected, e.g. via the S1 or X2 interface or the XN interface in NR, with each other via respective backhaul links 1161 to 1165, which are schematically represented in Fig. 1(b) by the arrows pointing to “gNBs”. A sidelink channel allows direct communication between UEs, also referred to as device-to-device (D2D) communication. The sidelink interface in 3GPP is named PC5. For data transmission a physical resource grid may be used. The physical resource grid may comprise a set of resource elements to which various physical channels and physical signals are mapped. For example, the physical channels may include the physical downlink, uplink and sidelink shared channels (PDSCH, PUSCH, PSSCH) carrying user specific data, also referred to as downlink, uplink and sidelink payload data, the physical broadcast channel (PBCH) carrying for example a master information block (MIB) and one or more of a system information block (SIB), the physical downlink, uplink and sidelink control channels (PDCCH, PUCCH, PSSCH) carrying for example the downlink control information (DCl), the uplink control information (UCI) and the sidelink control information (SCI). Note, the sidelink interface may a support 2-stage SCI. This refers to a first control region containing some parts of the SCI, and optionally, a second control region, which contains a second part of control information. For the uplink, the physical channels may further include the physical random access channel (PRACH or RACH) used by UEs for accessing the network once a UE synchronized and obtained the MIB and SIB. The physical signals may comprise reference signals or symbols (RS), synchronization signals and the like. The resource grid may comprise a frame or radio frame having a certain duration in the time domain and having a given bandwidth in the frequency domain. The frame may have a certain number of subframes of a predefined length, e.g. 1ms. Each subframe may include one or more slots of 12 or 14 OFDM symbols depending on the cyclic prefix (CP) length. A frame may also consist of a smaller number of OFDM symbols, e.g. when utilizing shortened transmission time intervals (sTTI) or a mini-slot/non-slot-based frame structure comprising just a few OFDM symbols. The wireless communication system may be any single-tone or multicarrier system using frequency-division multiplexing, like the orthogonal frequency-division multiplexing (OFDM) system, the orthogonal frequency-division multiple access (OFDMA) system, or any other IFFT-based signal with or without CP, e.g. DFT-s-OFDM. Other waveforms, like non-orthogonal waveforms for multiple access, e.g. filter-bank multicarrier (FBMC), generalized frequency division multiplexing (GFDM) or universal filtered multi carrier (UFMC), may be used. The wireless communication system may operate, e.g., in accordance with the LTE-Advanced pro standard, or the 5G or NR, New Radio, standard, or the NR-U, New Radio Unlicensed, standard. The wireless network or communication system depicted in Fig. 1 may be a heterogeneous network having distinct overlaid networks, e.g., a network of macro cells with each macro cell including a macro base station, like base station gNBi to gNB5, and a network of small cell base stations (not shown in Fig. 1), like femto or pico base stations. In addition to the above described terrestrial wireless network also non-terrestrial wireless communication networks (NTN) exist including spaceborne transceivers, like satellites, and/or airborne transceivers, like unmanned aircraft systems. The non-terrestrial wireless communication network or system may operate in a similar way as the terrestrial system described above with reference to Fig. 1 , for example in accordance with the LTE-Advanced Pro standard or the 5G or NR, new radio, standard. It is noted that the information in the above section is only for enhancing the understanding of the background of the invention and therefore it may contain information that does not form prior art that is already known to a person of ordinary skill in the art. Starting from a prior art as described above, there may be a need for enhancements or improvements in the signaling of a location or position of a user device.

Embodiments of the present invention are now described in more detail with reference to the accompanying drawings in which the same or similar elements have the same reference signs assigned. In a wireless communication system or network, like the one described above with reference to Fig. 1, location information of a user device, UE, may be transmitted as measurement information elements within a radio resource control, RRC, measurement report, as described, for example for LTE, in 3GPP TS 36.331 (see Reference [1]). Fig. 2 illustrates a location information field in RRC in as described in Reference [1]. The location is described as ellipsoid point coordinates and according to 3GPP TS 23.032 (see Reference [2]) the description of an ellipsoid point is that of a point on the surface of the ellipsoid and includes the latitude and the longitude. In practice, such a description may be used to refer to a point on the Earth’s surface or close to the Earth’s surface, with the same longitude and latitude. Fig. 3 illustrates a point as defined by the two coordinates defined by Reference [2]. More specifically, Fig. 3 illustrates a point P on the surface of the ellipsoid or earth E and its coordinates. The latitude is the angle between the equatorial plane A and a plane perpendicular to the tangent T on the ellipsoid surface at the point P. Positive latitudes correspond to the northern hemisphere, while negative latitudes correspond to the southern hemisphere. The longitude is the angle between the half plane G determined by the Greenwich meridian and the half-plane defined by the point P and the polar axis A, measured eastward. In Fig. 2, according to Reference [2], the following further elements may be defined as follows: the "ellipsoid point with uncertainty circle" is defined by the coordinates of an ellipsoid point P, the origin and a distance r, as is illustrated in Fig. 4 describing an uncertainty circle according to reference [2], the "ellipsoid point with uncertainty ellipse" is defined by the coordinates of an ellipsoid point P, the origin, distances r1 and r2 and an angle of orientation A as is illustrated in Fig. 5 describing an uncertainty ellipse according to reference [2], the "high accuracy ellipsoid point with uncertainty ellipse” - compared to the "ellipsoid point P with uncertainty ellipse", the "high accuracy ellipsoid point with uncertainty ellipse" provides a finer resolution for the coordinates, and the distances r1 and r2, the “ellipsoid point with altitude” is defined as a point at a specified distance above or below a point P on the earth's surface; this is defined by an ellipsoid point with the given longitude and latitude and the altitude above or below the ellipsoid point as is illustrated in Fig. 6 describing an ellipsoid point with altitude according to reference [2], the "ellipsoid point with altitude and uncertainty ellipsoid" is defined by the coordinates of an ellipsoid point P with an altitude, the distances r1 (the "semi-major uncertainty"), r2 (the "semi-minor uncertainty") and r3 (the "vertical uncertainty") and an angle of orientation A (the "angle of the major axis") as is illustrated in Fig. 7 describing an ellipsoid point with altitude and uncertainty ellipsoid according to reference [2], the "high accuracy ellipsoid point with altitude and uncertainty ellipsoid" - compared to the "ellipsoid point with altitude and uncertainty ellipsoid", the "high accuracy ellipsoid point with altitude and uncertainty ellipsoid" provides a finer resolution for the co-ordinates, and distances r1 , r2, and r3. Fig. 8 illustrates the information element (IE) EllipsoidArc which describes a geographical location as an ellipsoid point in accordance with Reference [3]. Further, the above elements, namely ellipsoid point with uncertainty circle, ellipsoid point with uncertainty ellipse, high accuracy ellipsoid point with anti-ellipse, ellipsoid point with altitude, ellipsoid point with altitude and uncertainty ellipsoid, and high accuracy ellipsoid point with altitude and uncertainty ellipsoid may be employed. For these elements, the number of required bits is larger than the number of the bits for the information element EllipsoidArc. In the following, the number of required bits for each information element, IE, is described according to Reference [2] In accordance with reference [2], the coordinates of an ellipsoid point are coded with an uncertainty of less than 3 meters. The latitude is coded with 24 bits, namely 1 bit of sign and a number between 0 and 223-1 coded in binary on 23 bits. The relation between the coded number N and the range of absolute latitude X it encodes is as follows, with X in degrees: 223 N £ ~X < N + 1 (1) except for N = 223-1 , for which the range is extended to include N + 1. The longitude, expressed in the range of -180° to +180°, is coded as a number between -223 and +223-1 , coded in 2’s compliment binary on 24 bits. The relation between the coded number N and the range of longitude X it encodes is as follows, with X in degrees: 224 N£ x
