[0001] REPORTING ENHANCEMENT FOR MOBILITY Description The present invention relates to the field of wireless communication systems or networks, more specifically reporting procedures to measure and report beams from serving and neighboring cells. Embodiments of the present invention concern enhancements of CSI reporting, Layer 1 / Layer 2 Triggered mobility, LTM, reporting, measurement reporting, measurement events, time to trigger for L1 measurements and conditional handover, CHO and other conditional mobility procedures, e.g., conditional PSCell Addition or change, CPAC, or subsequent CPAC, SCPAC. Fig.1 is a schematic representation of an example of a terrestrial wireless network 100 including, as is shown in Fig.1(A), the core network, CN, 102 and one or more radio access networks RAN1, RAN2, …RANN. Fig.1(B) is a schematic representation of an example of a radio access network RANnthat may include one or more base stations gNB1to gNB5, each serving a specific area surrounding the base station schematically represented by respective cells 1061to 1065. 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, e.g., a base station in a 6G network. The BS may also comprise of integrated access and backhaul, IAB, nodes, e.g., an IAB Donor and / or IAB Node, consisting of a central unit, CU, as well as of a distributed unit, DU, and / or containing IAB-MTs including IAB mobile termination, MT. The term base station may refer to an access point, AP, in any of the WiFi standards, e.g., belonging to the IEEE 802.11-familiy. A user may be a stationary device or a mobile device. The wireless communication system may also be accessed by mobile or stationary IoT devices which connect to a base station or to a user. The mobile or stationary 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 RANnmay include more or less such cells, and RANnmay also include only

[0002] HHI - 2024P67305WO one base station. Fig.1(B) shows two users UE1and UE2, also referred to as user device or user equipment, that are in cell 1062and that are served by base station gNB2. Another user UE3is shown in cell 1064which is served by base station gNB4. The arrows 1081, 1082and 1083schematically represent uplink / downlink connections for transmitting data from a user UE1, UE2and UE3to the base stations gNB2, gNB4or for transmitting data from the base stations gNB2, gNB4to the users UE1, UE2, UE3. This may be realized on licensed bands or on unlicensed bands. Further, Fig.1(B) shows two further devices 1101and 1102in cell 1064, like IoT devices, which may be stationary or mobile devices. The device 1101accesses the wireless communication system via the base station gNB4to receive and transmit data as schematically represented by arrow 1121. The device 1102accesses the wireless communication system via the user UE3as is schematically represented by arrow 1122. The respective base station gNB1to gNB5may be connected to the core network 102, e.g., via the S1 interface, via respective backhaul links 1141to 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. The external network may be the Internet, or a private network, such as an Intranet or any other type of campus networks, e.g., a private WiFi communication system or a 4G or 5G mobile communication system. Further, some or all of the respective base station gNB1to gNB5may be connected, e.g., via the S1 or X2 interface or the XN interface in NR, with each other via respective backhaul links 1161to 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. Note, that the term user equipment, UE, or user device may also refer to a station, STA, as used in any of the WiFi standards, e.g., belonging to the IEEE 802.11-familiy. 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, and the physical sidelink broadcast channel, PSBCH, carrying for example a master information block, MIB, and one or more system information blocks, SIBs, one or more sidelink information blocks, SLIBs, if supported, the physical downlink, uplink and sidelink control channels, PDCCH, PUCCH, PSSCH, carrying for example the downlink control information, DCI, the uplink control information, UCI, and the sidelink control information, SCI, and physical sidelink feedback channels, PSFCH, carrying PC5 feedback

[0003] HHI - 2024P67305WO responses. The sidelink interface may support a 2-stage SCI which refers to a first control region containing some parts of the SCI, also referred to as the 1st-stage SCI, and optionally, a second control region which contains a second part of control information, also referred to as the 2nd-stage SCI. 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 have 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 Inverse Fast Fourier Transform, IFFT, based signal with or without Cyclic Prefix, CP, e.g., Discrete Fourier Transform-spread-OFDM, 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 3GPPs LTE, LTE-Advanced, LTE-Advanced Pro, or the 5G or 5G-Advanced or 6G or 3GPPs NR, New Radio, or within LTE-U, LTE Unlicensed or NR-U, New Radio Unlicensed, which is specified within the LTE and within NR specifications. 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 gNB1to 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

[0004] HHI - 2024P67305WO with reference to Fig.1, for example in accordance with the LTE-Advanced Pro or 5G or 5G-Advanced or NR, New Radio, or a possible future 6G radio system. In mobile communication networks, for example in a network like that described above with reference to Fig.1, like an LTE or 5G / NR network, there may be UEs that communicate directly with each other over one or more sidelink, SL, channels, e.g., using the PC5 / PC3 interface or WiFi direct. UEs that communicate directly with each other over the sidelink may include vehicles communicating directly with other vehicles, V2V communication, vehicles communicating with other entities of the wireless communication network, V2X communication, for example roadside units, RSUs, roadside entities, like traffic lights, traffic signs, or pedestrians. An RSU may have a functionality of a BS or of a UE, depending on the specific network configuration. Other UEs may not be vehicular related UEs and may comprise any of the above-mentioned devices. Such devices may also communicate directly with each other, D2D communication, using the SL channels. When considering two UEs directly communicating with each other over the sidelink, both UEs may be served by the same base station so that the base station may provide sidelink resource allocation configuration or assistance for the UEs. For example, both UEs may be within the coverage area of a base station, like one of the base stations depicted in Fig.1. This is referred to as an “in-coverage” scenario. Another scenario is referred to as an “out- of-coverage” scenario. It is noted that “out-of-coverage” does not mean that the two UEs are necessarily outside one of the cells depicted in Fig.1, rather, it means that these UEs - may not be connected to a base station, for example, they are not in an RRC connected state, so that the UEs do not receive from the base station any sidelink resource allocation configuration or assistance, and / or - may be connected to the base station, but, for one or more reasons, the base station may not provide sidelink resource allocation configuration or assistance for the UEs, and / or - may be connected to the base station that may not support NR V2X services, e.g., GSM, UMTS, LTE base stations or a WiFi AP. 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.

[0007] HHI - 2024P67305WO In conventional wireless communication networks or systems, like the one described above with reference to Fig.1, which may be a current 5G NR systems, a large overhead is caused by characterizing the radio channel and exchanging an estimate of the radio channel between user equipment, UE, and the base station, gNB, and potentially further neighboring stations, neighboring gNB, neighboring cells or neighboring beams. The overhead may be caused by the UE reporting large amounts of measurements for different reference signal types and neighboring cells. Furthermore, when applying conventional events used to trigger measurement reports on L3 to Layer 1 / Layer 2 Triggered mobility, LMT, systems using L1-based signal strength indicators, unnecessary overhead due to overreporting or too rare reporting due to large fluctuations in the value of L1-based signal strength indicator may be caused. 5G-Advanced and 6G systems may overcome some of the drawbacks mentioned here by utilizing enhanced reporting procedures, advanced events and protocols accordingly, and thus improve the overall system performance of 5G NR telecommunication systems. In particular, applying these new techniques to LTM can improve handover latency and interruption time compared to Layer 3-based mobility, especially when moving between cells, between cells of different gNBs, e.g., gNBs with different central units, CU, e.g., inter- CU mobility. Furthermore, enhancing LMT and conditional mobility mechanisms, e.g., CHO, with the above-mentioned new reporting schemes will increase robustness and shorten interruption times, for moving UEs in future cellular systems. Beam Management Beam management is a set of techniques to establish and maintain optimal directional links between the base station (gNB) and the user equipment (UE) in 5G networks, especially in frequency bands, e.g., millimeter wave (mmWave) or frequency bands above 6 GHz, e.g., sometimes named FR2 or FR3. Beam management involves the following procedures: ^ Beam sweeping: This is the process of covering a spatial area with a set of beams transmitted and received according to pre-specified intervals and directions. ^ Beam measurement: This is the evaluation of the quality of the received signal at the gNB or at the UE, using metrics such as RSRP, RSRQ, SINR, or SNR. ^ Beam determination: This is the selection of the suitable beam or beams either at the gNB or at the UE, based on the beam measurements. ^ Beam reporting: This is the procedure used by the UE to send beam quality and beam decision information to the gNB. Beam management is performed in both idle mode (when the UE does not have active data transmission) and connected mode (when the UE is exchanging data with the gNB). In idle

[0008] HHI - 2024P67305WO mode, the UE uses the synchronization signal block (SSB) to perform initial access and cell search. The SSB consists of the primary and secondary synchronization signals (PSS and SSS) and the physical broadcast channel (PBCH), which carry essential information for the UE to synchronize and connect to the gNB. The SSB is transmitted using a fixed beam pattern that covers the entire cell. The UE measures the SSB and reports the best beam index to the gNB. The gNB then uses the reported beam index to steer the beam towards the UE for subsequent transmissions. In connected mode, the UE and the gNB use different reference signals for beam management. The gNB uses the channel state information reference signal (CSI-RS) to transmit beams for the UE to measure and report. The UE uses the sounding reference signal (SRS) to transmit beams for the gNB to measure and determine the best beamforming direction. The gNB and the UE also exchange beam failure and recovery information using the radio link control (RLC) and medium access control (MAC) protocols. In connected mode, the gNB configures the UE with multiple CSI-RS resources, which describe a CSI-RS (reference symbol) in terms of the REs it is transmitted on and its periodicity, its bandwidth, its time offset, etc. One or more CSI-RS resources are bundled in CSI resource sets. One or more CSI resource sets belong to a CSI resource configuration that is usually associated to a CSI report configuration. The CSI-ReportConfig defines how often and when a UE is supposed to report the measurements, e.g. periodically or triggered etc. Then the UE reports per CSI resource set. For beam management purposes, the UE is usually configured to report the L1-RSRP. Then, in a reporting occasion the UE determines up to 4 (depends on configuration) strongest beams and reports their CSI-RS resource indicator (CRI) and the associated L1- RSRP. The CRI is the index of a CSI-RS resource within a CSI resource set by which the beam is uniquely identified. Although the specification may not explicitly specify beams or beam IDs, in practical deployments, each CSI-RS resource is transmitted using a specific refined beam. Hence, the CRI identifies a CSI-RS resource and by that a specific beam. So the terms CRI and beam or beam ID or CSI-RS or CSI-RS resource may be used interchangeably. Furthermore, when the gNB actually transmits data, i.e. PDSCH, to the UE it uses the Transmit Configuration Indicator (TCI) that may be configured or indicated explicitly in the DCI. The TCI state links a data transmission, PDSCH or PUSCH, to up to two reference signals, e.g. a CSI-RS, SSB, SRS etc. Furthermore, it states shared properties of the beams in the form of the quasi-co-location (QCL) parameter. For example,

[0009] HHI - 2024P67305WO if an SSB and a PDSCH is linked with QCL Type D, it means that they only share Rx properties. In particular, this means that the gNB may use a fine beam for the PDSCH but a coarse beam for the SSB. Both beams although being different share the same direction, hence they are QCLed Type D. In practice, this means that the UE may use the same Rx beam to receive the PDSCH but cannot assume that other parameters are the same. Furthermore, the UE may link a CSI-RS resource to the PDSCH with QCL Type A, which essentially means that the PDSCH and the CSR-RS have been transmitted using the same beam. Hence, the UE can use more reception parameters, such as the Doppler shift, Doppler spread, average delay, delay spread, that it obtained from measuring the said CSI- RS to equalize and decode the PDSCH reception. Thus, the TCI or TCI state essentially also identifies a certain beam or beam ID and hence, can be used interchangeably. Furthermore, beams may be measured using reference signals, e.g. CSI- RS or SSB, for that purpose, the gNB may use a certain beam to transmit a certain reference signal that is measured at the UE. This can be referred to as the UE measuring a beam. In particular, one reference signal may be used to convey a beam allowing the UE to measure that beam. Hence, the term “a reference signal” may be used interchangeably to refer to a beam. In the RRC_CONNECTED mode, network-controlled mobility utilized for UEs is classified into two categories of mobility: cell-level mobility and beam-level mobility. Beam level mobility includes intra-cell beam level mobility and inter-cell beam level mobility. Furthermore, in case of C-RAN or IAN network, gNBs may share the same central unit, CU, or may be attached to different CUs. When a UE is moving between CUs, this may be referred to as inter-CU mobility, e.g., inter-CU handover, HO. Note, that a inter-CU HO may require additional signalling between gNBs and may thus cause additional latency or interruption time, especially when many UEs are moving between cells and performing inter-CU HOs. Cell level handover involves the handover process where a UE switches from a serving cell to a different neighboring cell. Cell selection occurs whenever a new camping cell is better than the serving cell in terms of the measured parameters, e.g. Reference Signal Received Power (RSRP) or Reference Signal Received Quality (RSRQ). In intra-frequency handover, a UE transitions between various cells that operate on the same frequency. Conversely,

[0010] HHI - 2024P67305WO when the serving and target gNB are on different carrier frequencies, they are considered to be inter-frequency neighbors. At the beam-level, a handover refers to the procedure where the UE transitions between beams within the same and different cells. Beam level mobility is carried out based on CSI- RS. The UE may evaluate for the following measurement events when moving through cellular systems. Here, a measurement event is a condition which should be fulfilled before the measured value is reported to the network. NR currently supports the following six different intra-RAT triggering conditions or events, that can be configured: Event A1 Serving becomes better than threshold Event A2 Serving becomes worse than threshold Event A3 Neighbour becomes offset better than serving cell Event A4 Neighbour becomes better than threshold Event A5 Serving becomes worse than threshold1 and neighbour becomes better than threshold2 Event A6 Neighbour becomes offset better than SCell Note that one usage of A1 could be to cancel an ongoing handover if the device suddenly moves back into good coverage of the current cell, before the handover is completed. For A2, this event does not involve measurements on other cells than the serving cells, and could trigger a handover in case a UE moves closer to the cell edge. A3, compares the serving cell to a candidate cell, e.g., a neighboring cell. It could thus be used in case a UE moves to the cell edge, and another cell becomes better than the serving cell. A4, only considers the signal strength of a neighboring cell. One possible usage could be to trigger a handover for load balancing reasons. A5, could be used in a similar fashion as the A3 event. Finally, A6 could be used to determine SCells which could be used for carrier aggregation. L3-Measurements Reporting In 5G NR, RSRP measurements may be performed and reported at Layer 1 and / or Layer 3. For example, UE can provide SS-RSRP measurements at Layer 1 when sending CSI and at Layer 3 when sending an RRC: Measurement Report to gNB. Below is a representation of the legacy measurement reporting procedure taken from the 3GPP TS 38.331 (5.5.5) specification as indicated in Fig.2.

[0011] HHI - 2024P67305WO Measurements are filtered at Layer 3 to remove the impact of fast fading and to reduce short-term variations in the obtained results. In general, it brings benefits for performing radio resource management decisions, which require a long-term view of channel conditions, e.g. handover procedures.^^ ^ The general form of the filtering equation for L3 filtering can be represented as (3GPP TS 38.3315.5.3.2):^ ^ Fn= (1 – a)*Fn-1+ a*Mn^ where^ Mn is the latest received measurement result from the physical layer, e.g. L1-RSRP^ Fn is the updated filtered measurement result, that is used for evaluation of reporting criteria^ Fn-1 is the old filtered measurement result and^ a is the filtering coefficient, often referred to as the filter constant or weighting factor, a = 1 / 2(k / 4), where k is the filterCoefficient for the corresponding measurement quantity received by the quantityConfig It determines the influence of the current L1 measurement on the filtered result. A smaller value of a results in a smoother but slower response to changes, while a larger value allows the filter to respond more quickly to variations.^ FilterCoefficient ::= ENUMERATED { fc0, fc1, fc2, fc3, fc4, fc5, fc6, fc7, fc8, fc9, fc11, fc13, fc15, fc17, fc19, spare1, ...} Value fc0 corresponds to k^= 0, fc1 corresponds to k = 1, and so on. In summary, the L3 filtering equation combines historical information with current measurements to produce a smoothed representation of the channel conditions, which is valuable for making radio resource management decisions in 5G NR networks. Adjusting the filtering coefficient allows for a trade-off between responsiveness to changes and stability of the filtered result.^ LTM reporting

[0012] HHI - 2024P67305WO Fig.2b illustrates the mapping of CRI, SSBRI, RSRP as given in the tables in 3GPP TS 38.212 v17.7.0, e.g., based on a scenario as described in connection with Fig.2a. Embodiments of the present invention may be implemented in a wireless communication system as depicted in Fig.1 including base stations and users, like mobile terminals or IoT devices. Fig.3 is a schematic representation of a wireless communication system 310 including a transmitter 300, like a base station, and one or more receivers 302, 304, like user devices, UEs. The transmitter 300 and the receivers 302, 304 may communicate via one or more wireless communication links or channels 306a, 306b, 308, like a radio link. The transmitter 300 may include one or more antennas ANTTor an antenna array having a plurality of antenna elements, a signal processor 300a and a transceiver 300b, coupled with each other. The receivers 302, 304 include one or more antennas ANTUEor an antenna array having a plurality of antennas, a signal processor 302a, 304a, and a transceiver 302b, 304b coupled with each other. The base station 300 and the UEs 302, 304 may communicate via respective first wireless communication links 306a and 306b, like a radio link using the Uu interface, while the UEs 302, 304 may communicate with each other via a second wireless communication link 308, like a radio link using the PC5 or sidelink, SL, interface. When the UEs are not served by the base station or are not connected to the base station, for example, they are not in an RRC connected state, or, more generally, when no SL resource allocation configuration or assistance is provided by a base station, the UEs may communicate with each other over the sidelink. The system or network of Fig.3, the one or more UEs 302, 304 of Fig.3, and the base station 300 of Fig.3 may operate in accordance with the inventive teachings described herein. First Aspect A first aspect of the present invention concerns a joint measuring of different types of reference signals, RS, e.g., of SSBs and CSI-RS.

[0031] HHI - 2024P67305WO Computer Program Product The present invention provides a computer program product comprising instructions which, when the program is executed by a computer, causes the computer to carry out one or more methods in accordance with the present invention. Embodiments of the present invention are now described in more detail with reference to the accompanying drawings. It is noted that the subsequently outlined and described aspects or embodiments may be combined such that some or all of the aspects / embodiments are implemented within one embodiment. Further, when referring herein to determining one or more beams, this may mean selecting a set of beams. It may also mean to measure one or more beams, i.e., determine certain parameters that characterize each of the one or more beams. For example, such parameters may comprise but are not limited to SINR, RSRP, RSRQ, SNR, etc. Furthermore, when referring to predicting a performance parameter or performance parameter value of a beam or predicting a beam using an AI / ML model or functionality, this may refer to the output of the AI / ML model or functionality with respect to said beam, where the output may be a predicted performance parameter value, e. g, a RSRP value, RSRQ value, SINR value, or SNR value, or an indication that the beam belongs to the set of Top- K beams, or a ranking index defining an order over the one or more beams. First Aspect In the following, embodiments of the first aspect of the present invention are described in more detail. The first aspect relates to using a measurement configuration for more than just a single type of reference signals whilst allowing to report on one or more reference signal types. Joint Measuring of different types of reference signals such as SSBs and CSI-RS Fig.4 illustrates a user device, UE, 400 in accordance with embodiments of the first aspect of the present invention. The UE 400 includes a signal processor or signal processing module 402 and one or more antennas 404. The UE 400 receives, via the antenna 404, one or more reference signals from a network entity of the wireless communication network, for example the UE 400 receives from a gNB 406 the one or more reference signals over the Uu interface 408. The UE 400 may also receive the reference signals from a further UE

[0032] HHI - 2024P67305WO 410 over the sidelink or PC5 interface 412. The UE 400 comprises a measurement module 414 to perform measurements of one or more of the received reference signals so as to obtain for each of one or more performance parameters, one or more performance parameter values. The measurement module 414 may also determine one or more beams received at the UE, e.g., from the gNB 406 or the UE 410 which are identified by the one or more reference signals. Further addition, the UE 400 may include an optional AI / ML module 416 operating or running at least one Artificial Intelligence / Machine Learning, AI / ML, model or functionality. The AI / ML module 416 may operate on the basis of input data 415, like the measurements obtained by the measurement module 414. Using the measurements 415, the AI / ML module 416 predicts, for a certain performance parameter, one or more values. The AI / ML module 416 may also predict, using the measurements 415, one or more of the above-mentioned beams. In accordance with embodiments, the measurement module 414 optionally in combination with the AI / ML module 416 enable the UE 400 to obtain one or more of the performance values or beams by a measurement while one or more other performance values or beams. In accordance with yet other embodiments, the UE 400 is capable to obtain all of the values and / or all of the beams by use measurements performed by the measurement module 414, optionally additionally subsect of prediction performed by the AI / ML module 416. The UE 400 further includes a reporting module 418 allowing the UE to transmit to a network entity, like the gNB 1406 or the UE 410, a report including the one or more performance parameter values and / or the one or more beams measured and / or predicted using the measurement module 414 and / or the AI / ML module 416. The report created by the reporting module 418 and transmitted by the UE 400 via the one or more antennas 404 to the network entity includes at least one predicted performance parameter value and / or at least one predicted beam. The report may be sent to the network entity which provided the one or more reference signals, like the gNB 406 or the UE 410, or to another network entity. Neither the LTM reporting framework nor the CSI reporting framework nor the traditional Handover (HO) framework support reporting of SSB-based and CSI-RS-based measurements at the same time in the same measurement configuration. Usually, the NW uses two separate measurement configurations to enable measuring and reporting of both. However, especially for the LTM case, the UE may have to tune to a different frequency band to perform the measurements. During this time, the UE is not able to receive from the serving cell. Therefore, in this invention embodiments propose that the NW configures the

[0033] HHI - 2024P67305WO UE to conduct L1 measurements based on two or more types of reference signals, namely the rsType or reference symbol type, e.g., SSB, CSI-RS, PRS, PT-RS, SRS and / or DM-RS, in the same measurement configuration. This reduces the configuration effort and potentially the time that the UE has to spend with measuring a different cell. Furthermore, it reduces the reporting overhead since only relevant measurements of both reference signals are reported. Furthermore, if configured in a joint configuration, parts of the configuration, e.g., timing constraints of a measurement or aging of measurement data can be aligned among the different rsTypes. In this way, it could be ensured that measurement data from different rsTypes is recorded within a certain time window, and that recorded measurement data reflects the same channel condition observed by the UE performing the measurements. RRC protocol at Layer 3 may serve as a framework for configuration signaling. For instance, an information element (IE) designated as “NR-RS-Type” within the CSI report configuration could be assigned the value ‘both’ or to ‘ssb+csi-rs’, to signify that measurements are being executed based on both SSB and CSI-RS signals. In its turn, the NW will benefit in receiving the more accurate measurements of the beams that refer to the strongest and most reliable beams detected by the UE. An example in the context of the traditional HO framework can be seen in Fig.5. Therein, by use of, e.g., code implementing the pseudo-code NR-RS-Type ::= ENUMERATED {ssb, csi-rs, both} A UE may be configured according to an embodiment to measure on either SSBs (or a different reference signal, RS, of a first type), or a CSI-RS (or a different RS of a second type) or both, wherein the example, may be extended to at least a third type of RS and, thus, combinations of 2 different types of RS and a measurement of 3 types of RS. For example, a non-zero-power channel state information reference signal, NZP-CSI-RS- ResourceSet and a csi-SSB-ResourceSet may be configured in the same CSI- ResourceConfig, as shown in Fig.6, see in particular lines 4 through 8. In another example, both a CSI resource set and an SSB resource set may be configured in the LTM-CSI-Resource-Config as illustrated in Fig.7, see in particular line 4. Blend Report

[0034] HHI - 2024P67305WO In this section, embodiments provide a UE that may be configured to transmit a blend report or combined report that encompasses both CSI-RS and SSB results within a single measurement report. According to such an embodiment, the measurement report includes one or more beam information, where at least one beam information relates to a CSI-RS and at least another one relates to an SSB. Beam information may comprise a beam ID (BID), e.g. CRI or SSBRI or SSB Index or CSI-RS ID, and / or a beam strength indicator, e.g. RSRP or SINR. In a further embodiment, the number of reported beam information N may be variable or configured or preconfigured. For example, the UE may report always a same number N of beam information in each report. This may be the beam information of the N strongest beams. In another example, the UE may report only beam information of beams that have a strength, e.g. RSRP or SINR, above a certain threshold. Hence, depending on the actual measurement outcome the number of reported beam information may vary. Furthermore, a configuration or preconfiguration may indicate a number of beam information associated with CSI-RSs NCSIand / or another number of beam information associated with SSBs NSSB, respectively, where NCSIand NSSBmay be equal or different. For example, the UE may be configured to always report NCSIbeam information of the NCSIstrongest beams associated with CSI-RSs and NSSBbeam information of the NSSBstrongest beams associated with SSBs. In this case, the report would be divided into two parts, one part associated with CSI-RSs and one part associated with SSBs. For example, if RSRP or SINR reporting is activated, the UE would report one absolute RSRP or SINR and NCSI– 1 differential RSRPs or SINRs in the CSI-RS part, and one absolute RSRP or SINR and NSSB– 1 differential RSRPs or SINRs in the SSB part. Note that NCSIis considered to use the CSI as a place holder for a reference signal of a first type and that NSSBis considered to use the SSB as a place holder for a reference signal of a second type of reference signals where any other types of reference signals may be used instead of CSI, SSB respectively, e.g., reference signals described herein. Thus, NCSImay also be represented as NRST1and NSSBmay also be represented as NRST2, RST meaning a reference signal type.

[0035] HHI - 2024P67305WO Also, NCSIand NSSBmay be variable, i.e. dynamically determined based on the measurement results. In this embodiment, a further constraint may be given by N = NCSI+ NSSB. Hence, only the total number of beam information N is configured or preconfigured and can be dynamically allocated to beam information associated with CSI-RSs or SSBs. For example, the total number of reported beam information may be fixed by a configuration or preconfiguration and the beam information may be dynamically allocated to beams associated CSI-RSs or SSBs, e.g., report the N strongest beams over the set of CSI-RS and SSB beams. For example, if RSRP or SINR reporting is activated, the UE may report first NCSIand / or NSSBallowing the receiver to understand how many CSI beams and how many SSB beams are reported. Then it may report the strongest CSI-RS beam as an absolute RSRP or SINR and the remaining CSI-RS beams as differential RSRP or SINR with respect to the strongest CSI-RS beam and further, it may report the strongest SSB beam as an absolute RSRP or SINR and the remaining SSB beams as differential RSRP or SINR with respect to the strongest SSB beam. Hence, the UE would report two absolute RSRPs or SINRs and N-2 differential RSRPs or SINRs. If at least one of N, NCSIor NSSBis variable, the report procedure may be comprised of a two stage approach, where in the first stage, the report indicates the value of at least one of N, NCSIor NSSBand the second stage, the report provides the actual beam information. In a further embodiment, the size of the BID, e.g. CRI or SSBRI or SSB Index or CSI-RS ID, may be determined such that it is aligned for beams associated with a CSI-RS and an SSB. This has the motivation that in the current procedure the size of the CRI is determinedas⌈^^^^^^^^^^^^2(^^^^^^^^^^^^^^^^^^^^−^^^^^^^^)⌉and the size of the SSBRI is determined as⌈^^^^^^^^^^^^2(^^^^^^^^^^^^^^^^^^^^)⌉, where ^^^^^^^^^^^^^^^^^^^^−^^^^^^^^is the number of CSI-RS in the current resource set and ^^^^^^^^^^^^^^^^^^^^is the number of SSBs in the current resource set. Obviously, depending on the configuration these two numbers may be different. In the case where the beam information is dynamically allocated to CSI-RS or SSB beams, this causes an issues because the total report size would depend on the number of reported SSB beams and CSI-RS beams. For example, to mitigate that issue, the size of the BID, which is determined based on the CRI or the SSBRI, may be determined asmax (⌈^^^^^^^^^^^^2(^^^^^^^^^^^^^^^^^^^^−^^^^^^^^)⌉, ⌈^^^^^^^^^^^^2(^^^^^^^^^^^^^^^^^^^^)⌉ ) or ⌈^^^^^^^^^^^^2(max (^^^^^^^^^^^^^^^^^^^^−^^^^^^^^ ,^^^^^^^^^^^^^^^^^^^^))⌉ or ⌈^^^^^^^^^^^^2(^^^^^^^^^^^^^^^^^^^^−^^^^^^^^ +^^^^^^^^^^^^^^^^^^^^)⌉. In the first two examples, the BID may be determined as BID = CRI, if beam is a CSI-RS beam, and BID = SSBRI, if beam is a n SSB beam. In the third example, the BID may be determined as BID = CRI, if beam is a CSI-RS beam, and BID = SSBRI + ^^^^^^^^^^^^^^^^^^^^−^^^^^^^^, if beam is an SSB beam. Another example is BID = ^^^^^^^^^^^^^^^^^^^^+ CRI, if beam is a CSI-RS beam, and BID = SSBRI, if beam is an SSB beam.

[0036] HHI - 2024P67305WO In another embodiment, the BID may also comprise an CSI-RS / SSB indicator, e.g. one extra bit. This indicator may indicate whether the reported BID is a BID associated with a CSI-RS or associated with an SSB. For example, if RSRP or SINR reporting is activated, if the BID comprises the CSI-RS / SSB indicator or the BID is calculated such that CRIs and SSBRI can be distinguished, e.g. see last example in the paragraph above, then the UE may report one absolute RSRP or SINR of the strongest beam, regardless of CSI-RS or SSB, and N-1 differential RSRPs or SINRs of CSI-RS and / or SSB beams. Fig.8a-c illustrate different reporting modes, as described above and in accordance with embodiments. In connection with Fig.9a-b, by use of pseudo code illustrating a functionality to be encoded and according to another example is provided, showing how the CSI-ReportConfig may be extended such that reporting of SSBs and CSI-RSs can be supported within the same configuration. According to embodiments, a selection or configuration is provided, e.g., according to lines 38 through 42 shown in Fig.9b.

According to an embodiment, the UE is configured for reporting in the report as a same report: - any n distinct types of reference signals (from claim 2) for n = {2, 3, 4, 5, 6}.

[0038] HHI - 2024P67305WO According to an embodiment, the UE is configured for applying an aligned timing constraints of the measurement and / or of an aging of measurement data for the different types of reference signals.

According to an embodiment, the number of beam information is based to at least one of: • a number of strongest beams; • a number resulting from beams that have a strength, e.g. RSRP or SINR, above a signal strength threshold; • a number resulting from beams that have a predefined measurement value.

[0039] HHI - 2024P67305WO According to an embodiment, the UE is adapted for operating according to a configuration or preconfiguration indicating a number of beam information associated with reference signals of a first type of the at least two types of reference signals , NRST1, and / or another number of beam information associated with reference signals of a second type of the at least two types of reference signals, NRST2; wherein NRST1and NRST2may be equal or different. According to an embodiment, the UE is configured for implementing a configuration according to which the UE reports NRST1beam information of the NRST1strongest beams associated with reference signals of a first type of the at least two types of reference signals and reports NRST2beam information of the NRST2strongest beams associated with reference signals of a second type of the at least two types of reference signals. According to an embodiment, the UE is adapted to divide the report reporting at least a part of the measurements into two parts, one part associated with reference signals of the first type and one part associated with reference signals of the second type. According to an embodiment, the UE indicates the number of reported beam information associated with a first type of reference signals and / or a second type of reference signals in the report. According to an embodiment, the UE indicates the number of reported beam information associated with a first type of reference signals and / or a second type of reference signals in the report and / or the number of total reported beams in a first stage and the one or more beam information in a second stage. According to an embodiment, the UE is to determine a size of a beam ID, BID, associated with the first type of reference signals as being aligned with the size of a beam ID, BID, associated with the second type of reference signals. According to an embodiment, the BID comprises an indicator such as a CSI-RS / SSB indicator, e.g. one extra bit, to indicate a type of reference signal to which the BID relates. According to an embodiment, the UE is to operate according to an RSRP reporting or an SINR reporting or an RSRQ reporting or an RSSI reporting;

[0040] HHI - 2024P67305WO wherein the UE is to report one absolute RSRP or SINR or RSRQ or RSSI of a strongest beam measured, e.g., regardless of CSI-RS or SSB, and N-1 differential RSRPs or SINRs or RSRQs or RSSIs. According to an embodiment, the UE is to operate according to an RSRP reporting or an SINR reporting or an RSRQ reporting or an RSSI reporting; wherein the UE is to report one absolute RSRP or SINR or RSRQ or RSSI of a strongest beam measured associated with the first type of reference signals, and one absolute RSRPs or SINRs or RSRQs or RSSIs of a strongest beam measured associated with the second type of reference signals. A method for operating such a user device, UE, in a wireless communication network comprises: implementing a report configuration associated with measurements on at least two types of reference signals; and reporting at least a part of the measurements in a report according to the report configuration. Second aspect Embodiments of the second aspect of the present invention are now described. In accordance with embodiments of the second aspect of the present invention, a colocation information quasi collocated, QCL, is used for measuring on reference signals. Dynamic QCL for CSI-RS In NR Release 19, the introduction of CSI-RS for LTM is discussed. In contrast to SSBs that are already supported by LTM, CSI-RS allow the measuring of finer and narrower beams. However, CSI-RS are short signals (usually 1 OFDM symbol) so that the measuring UE needs to know ahead which receive beamformer is appropriate for the reception of a CSI- RS. A straightforward solution would be to introduce the same parameters for LTM-CSI-RS that are already used for CSI-RS for mobility. In particular, CSI-RS for mobility uses the associated SSB field and the isQuasiColocated field in the CSI-RS-Resource-Mobility IE in RRC to define an TypeD quasi-colocation (QCL) to the associated SSB. When a UE

[0041] HHI - 2024P67305WO assumes a TypeD QCL of a signal to another reference signal, it means that the UE may use the same receive beamformer to receive the signal, i.e. the Type D QCL indicates that the same spatial Rx parameter can be used for receiving of both reference signals. For example, the UE may use the SSB to determine an appropriate receive beamformer to receive that SSB. Afterwards, it can use the same receive beamformer to receive a TypeD QCLed CSI-RS. However, for that the NW has to know how different SSB beams are received by the UE to find narrow beams that are potentially suitable and to configure their QCL properties. Due to the RRC signaling this is very slow and dynamically adapting to the current requirements is not possible. Hence, embodiments relate to a dynamic adaption of the QCL properties of a CSI-RS. This may be a CSI-RS for LTM, for beam management or for mobility in general. Dynamic indication of QCL In the first embodiment, the QCL of a CSI-RS may be dynamically indicated, e.g., using a DCI or a MAC CE. For example, the DCI may be a DCI format that triggers an aperiodic CSI report. In one alternative, different sets of QCLs for the CSI-RS of the CSI report may be configured and preconfigured and the DCI and / or MAC CE may indicate which one of the sets of QCLs to apply for receiving the CSI-RSs. A set of QCLs may indicate for each CSI-RS of the CSI report config an associated QCLed, e.g. TypeD, reference signal, e.g. an SSB or another CSI-RS. In another alternative, the DCI and / or MAC CE may indicate one SSB or CSI-RS, which is assumed to be QCLed to all CSI-RS of the CSI report configuration or CSI resource set. In a further alternative, the DCI and / or MAC CE may indicate for each CSI-RS of the CSI report config or associated CSI resource setting or CSI resource set to which other reference signal, e.g. SSB or CSI-RS, it is QCLed. In a further embodiment, an indication of a different QCL reference signal may only be applied a certain time after the reception of the indication has passed. In another alternative, the indication of a different QCL reference signal may be associated to a time interval for which the indicated QCL remains applicable. Once the time interval elapses, the UE may wait for a new indication or keep using the same QCL type. Implicit determination of QCL In another embodiment, the QCL of a CSI-RS may be implicitly determined. In particular, the QCL may be determined based on a past reference report, e.g., an LTM report, a

[0042] HHI - 2024P67305WO mobility report, or a RSRP or SINR report or a CSI report. The past reference report may be determined as a certain report, e.g., latest or earliest, out of a set of reports. The set of reports may be determined based on one or more of the following: • Time between (the past report measurement occasion or the reporting occasion of the past report) and (the current measurement occasion or the CSI-RS), e.g., the most recent past report or the most recent past report that has been sent at least a certain time before the measurement occasion, e.g. a minimum duration Tmin• Frequency of a report, e.g., periodic, semi-persistent, aperiodic • Type of a report, e.g., mobility report, LTM report, CSI report, RSRP report, SINR report, • Content of a report, e.g., whether based on SSBs or CSI-RSs or both • Whether report is associated is with the CSI-RS or with current report config that the CSI-RS is part of • Whether the results of the report config have been reported • A cell or gNB that is measured by the past report, e.g., in which cell the measured SSBs or CSI-RSs are • A cell or gNB that the past report is associated to, e.g., which cell configured the past report Based on the past reference report the UE may determine a QCL reference signal, e.g., SSB or CSI-RS, from the past reference report that is QCLed, e.g., TypeD, to the CSI-RS based on one or more of the following: • Signal strength, e.g., value of the reported RSRP or SINR • Reporting order, e.g., reported first or last • Quantization type, e.g., absolute or differential quantization of the RSRP or SINR For example, the UE may take the latest past report that has been reported to the gNB at least a certain time before measuring the CSI-RS and contains SSBs of the cell in which the CSI-RS is. Then, it may assume that the CSI-RS is TypeD QCLed to the strongest reported SSB of that cell in the past reference report. Because the gNB knows that assumption of the UE and finer beams pointing into the same direction of the strongest SSB are good beam candidates, it would send such beams in the CSI-RS resources. This allows the UE to measure these beams appropriately without requiring RRC reconfiguration or any explicit indication.

[0043] HHI - 2024P67305WO Fig. 10 shows a schematic block diagram of a base station 406 adapted to provide, for example, first reference signals such as SSBs 5021, 5022and / or 5023or a different number thereof. A UE according to an embodiment may have performed measurements on the SSBs or the first type of reference signals and may have provided a report 510 to the network indicating, for example, SSB 5022(SSB#1) as strongest beam. In a subsequent measurement and based on the knowledge about SSB 5022being the strongest beam, a different type of reference signals may be transmitted by base station 406 in time t1being spaced from the prior report or prior scenario at time t0by a minimum time duration Tminthat is described, by way of example only, in connection with Fig.15. Based on knowledge about the location of the UE, the channel condition respectively, the co-location information may be used in order to assume that a second type of reference signals such as CSI-RS#05041and CSI- RS#15042are provided for measurements to the UE whilst the UE may use, for example, the same receive beam formers using the co-location information. Based on the co-location type, e.g., TypeD (wherein other Types e.g., TypeA, TypeB and / or TypeC are also possible), this may allow for a quick measurement of the second type of reference signal, e.g., the CSI-RS, whilst avoiding adjustment of the receive beam former. A user device, UE, for a wireless communication network, according to the second aspect, e.g., UE 400, is configured to measure a first reference signal using a colocation information associating the first reference signal with a second reference signal, wherein the colocation information is indicated explicitly by a dynamic signaling, e.g. DCI or MAC CE, or is indicated implicitly. According to an embodiment, the UE is to measure the first reference signal as being of a first type, wherein the second reference signal is of a different second type. According to an embodiment, the first type is a channels state information reference signal, CSI-RS, wherein the second type is a system synchronization block, SSB. According to an embodiment, the UE is to receive the colocation information with a downlink control information, DCI, or a medium access control - control element, MAC CE.

[0044] HHI - 2024P67305WO According to an embodiment, the UE is configured or preconfigured with a set of colocation information such as, QCLs, associating different reference signals with the first reference signal, wherein the DCI and / or MAC CE indicates which one of the QCLs to apply for measuring the reference signal. According to an embodiment, the UE is adapted to apply an indication of a different QCL reference signal only a certain time after the reception of the indication has passed; or to apply the indication of a different QCL reference signal associated to a time interval for which the indicated QCL until receiving a new indication. According to an embodiment, the UE is to use the colocation information from an indication of a different quasi-colocation, QCL, reference signal a configured or preconfigured time after a reception of the indication, e.g., and to update or dismiss the colocation information thereafter. According to an embodiment, the UE is to use the colocation information from an indication of a different quasi-colocation, QCL, reference signal a configured or preconfigured time after a reception of the indication and to update the colocation information thereafter upon reception of an updated QCL indication and to apply the colocation information after the configured or preconfigured until the update. According to an embodiment, the UE is to implicitly determine the colocation information based on a past reference report, e.g., an LTM report, a mobility report, or a RSRP or SINR report or a CSI report. According to an embodiment, the past reference report is determined as a certain report of a set of prior reports, e.g., latest or earliest, out of a set of reports. According to an embodiment, the set of reports is determined based on one or more of the following: • a lapsed time, e.g., between the past report measurement occasion or the reporting occasion of the past report and the current measurement occasion or the CSI-RS, e.g., the most recent past report or the most recent past report that has been sent at least a certain time before the measurement occasion, e.g. a minimum duration T_min • a frequency of a report, e.g., periodic, semi-persistent, aperiodic

[0045] HHI - 2024P67305WO • a type of a report, e.g., mobility report, LTM report, CSI report, RSRP report, SINR report, RSSI report, RSRQ report • a content of a report, e.g., whether based on SSBs or CSI-RSs or both • whether the report is associated is with the CSI-RS or with current report config that the CSI-RS is part of • whether the results of the report config have been reported • a cell or gNB that is measured by the past report, e.g., in which cell the measured SSBs or CSI-RSs are • a cell or gNB that the past report is associated to, e.g., which cell configured the past report According to an embodiment, the UE is to determine the colocation information, e.g., SSB or CSI-RS, from the past reference report based on one or more of the following: • a signal strength, e.g., value of the reported RSRP or SINR • a reporting order, e.g., reported first or last • a quantization type, e.g., absolute or differential quantization of the RSRP or SINR A method for operating such a user device, UE, in a wireless communication network comprises: measuring a first reference signal using a colocation information associating the first reference signal with a second reference signal, such that the colocation information is indicated explicitly by a dynamic signaling, e.g. DCI or MAC CE, or is indicated implicitly. Third aspect Embodiments of the third aspect of the present invention are now described. In accordance with embodiments of the third aspect an LTM reporting is provided that allows for a high flexibility. The current LTM reporting framework enables UE to report SSBRI and L1-RSRP for a measured beam. This reporting is configured by RRC layer parameter LTM-CSI- ReportConfig IE, which generates a report that includes the SSBRIs and L1-RSRPs. In a

[0046] HHI - 2024P67305WO single L1 measurement report instance, a maximum of four reference signals can be reported per cell, and within one reporting occasion, up to four cells may be reported. However, the number of reported cells and reported beams per cell is set by configuration. That means the UE will report always the configured number of beams per cell for the configured number of cells. This is an inefficient way of reporting because usually certain cells will have a better signal than others. Thus, more information about the strong cells may improve the decision taking of the gNB and / or NW. In our embodiment, the number of reported beam information, KC, may vary for each cell. For example, UE may report a different number of beam information for each cell. The beam information may be comprised by one or more of the following: • a beam ID (BID), e.g., CRI, SSBRI, CSI-RS index, or SSB index, beam index • beam strength indicator, e.g., RSRP, SINR, RSRQ. An example structure of a CSI report is shown in Fig.11. Fig.11 shows a schematic table for illustrating a CSI report that contains several pieces of information such as SS / PBCH block resource indicator, SSBRI, and measurement values such as RSRP. In one embodiment, the UE may be configured with different values of KCfor each cell. In another embodiment, the UE may be configured with N the number of reported beams only and the values of KCmay be determined dynamically, where the following equation has to be fulfilled: For example, the UE reports the BID of the N strongest beam(s) from candidate cell(s) along with the corresponding beam strength indicator, such as RSRP, RSRQ or SINR. This will result to reporting more beams from the stronger cells and less beams from the weaker cells. Furthermore, one or more additional criteria may be used:

[0047] HHI - 2024P67305WO • Report at least a certain number of beams per cell, wherein the certain number may be configured or preconfigured, e.g., at least one beam per cell, ∀^^^^ ∶ ^^^^^^^^ ≥ 1,• Report at max only a certain number of beams, wherein the certain number may be configured or preconfigured, e.g., maximum 4 beams per cell, ∀^^^^ ∶ ^^^^^^^^ ≤ 4,• Report beams of a cell only if at least one beam of the cell exceeds a certain threshold, wherein the threshold may be configured or preconfigured. Moreover, the number of reported beams for each cell can be associated with beam quality. For example, the UE may be configured or preconfigured with one or more threshold values. If the L1-RSRP of the measured beam from the candidate cell exceeds the threshold, it will be reported. In another embodiment, the number of reported beams for each cell can be tied to the measurement results distribution. In another embodiment, the number of reported beams for each cell is associated with the distribution of measurements results. For instance, the UE may perform measurements and take a configurable number, M, of L1-RSRP beam measurements. Additionally, it may conduct multiple measurements for the same beams to mitigate channel fluctuations or apply filtering techniques. Then it calculates the mean value of the measurements and generates the corresponding distribution of the measurements such as the beam L1-RSRP. If UE is configured with a threshold probability, it reports the beams that exceed the threshold along with this BID and / or L1-RSRP. Fig.12 shows a schematic block diagram of a wireless communication network according to an embodiment. Fig.12 shows a schematic block diagram of at least a part of a wireless communication network 1200 according to an embodiment comprising, for example, three or more base stations 4061, 4062and 4063and a user device, UE, such as UE 400, wherein other functionalities of the UE 400 relating to different aspects of the present invention may also be omitted. The UE 400 may measure reference signals or beams 502 and / or 504 of different cells, wherein, as described in connection with aspect 1, the reference signals may be of a same type or of different types. Reference signals 506i,jare labelled with parameter I referring to a cell of a base station i with i = 1, 2, 3 and reference signal or beam j thereof. Fig.12 further shows different types of reports 5101, 5102and 5103that may be provided in accordance with embodiments. For example, in a report 5101a varying parameter KCmay

[0048] HHI - 2024P67305WO be contained and the beam ID, BID, of a respective reference signal or beam 506i,jis provided, e.g., as fulfilling a predefined requirement such as being a best beam, above a threshold or the like. In a different report 5102a beam reporting with varying KCvalues for each cell may be provided. For one or more cells the BID and a measurement value such as the RSRP may be provided, e.g., for cells A and B being operated by base stations 4061and 4062. For a different cell, such as the cell C operated by base station 4063, the BID may be sufficient. In yet another embodiment presented in connection with report 5103, for some cells there may be provided an RSRP value for each of the measured beams. As may be seen from reports 5102and 5103one of the beams, e.g., a first reported beam or a strongest beam, may be provided with the absolute measurement value RSRP whilst for further beams in the same cell a differential value dRSRP may be provided. Deviations thereof are possible without limitations, e.g., providing the RSRP value for each beam which may require, however, additional bandwidth. A user device, UE, for a wireless communication network, in accordance with the third aspect, e.g., UE 400, is to perform measurements of reference signals from a plurality of cells and for providing a measurement report to report at least a part of the measurements from the plurality of cells; wherein the UE is to provide a report reporting a different number of beam information related to measured reference signals for different cells of the plurality of cells. According to an embodiment, the report comprises one or more beam information associated with one or more reference signals, the beam information comprising at least one of: • a beam ID, BID, e.g., CRI, SSBRI, CSI-RS index, or SSB index, beam index • a beam strength indicator, e.g., RSRP, SINR, RSRQ. According to an embodiment, the UE is adapted to determine the number of beam information such as a parameter KCreported for at least one cell based on a received configuration.

[0049] HHI - 2024P67305WO According to an embodiment, the UE is adapted for determining the number of beam information to be reported for a cell based on at least a configuration parameter such as N, indicating the number of beam information reported with the report. According to an embodiment, the UE is adapted for determining the plurality of numbers of beam information reported for a cell is such that: wherein Ncellis the number of the plurality of cells, N is the number of beam information reported with the report with N > 0 and Kcis a number of beam information reported for cell c. According to an embodiment, the UE is adapted for determining the number of beam information reported for a cell out of the plurality of cells based on a selection criterion. According to an embodiment, the UE determines the one or more beam information to be reported for the cell based on the selection criterion. According to an embodiment, the selection criterion is based on a beam strength indicator, such as RSRP, RSRQ or SINR. According to an embodiment, the selection criterion selects N beam information to be reported by ranking the beam information according to the beam strength indicators contained in the beam information, such as RSRP, RSRQ or SINR, and selecting the N strongest beam information from the ranked beam information. According to an embodiment, the selection criterion is such that a number of selected beam information per cell is larger or equal to a minimum number, wherein the minimum number is configured or preconfigured, e.g., at least one beam per cell. According to an embodiment, the selection criterion is such that a number of selected beam information per cell is less or equal to a maximum number, wherein the maximum number is configured or preconfigured, e.g., maximum 4 beams per cell.

[0050] HHI - 2024P67305WO According to an embodiment, the selection criterion is such that one or more beam information of a cell is only selected, if at least one beam strength indicator of the cell exceeds a threshold, wherein the threshold is configured or preconfigured. According to an embodiment, the number of beam information for a cell is determined based on a quality of the beams of the cell. According to an embodiment, the number of reported beams for each cell is based on a measurement results distribution. According to an embodiment, the UE is configured for conducting multiple measurements for a same beam, e.g., to mitigate channel fluctuations or apply filtering techniques. According to an embodiment, the UE is configured for calculating a mean value or a filtering of the multiple measurements. According to an embodiment, the UE is configured to determine a probability that the beam strength indicator exceeds a certain threshold using the multiple measurements and the selection criterion is wherein a beam information is selected based on the probability. A method for operating such a user device, UE, in a wireless communication network comprises: performing measurements of reference signals from a plurality of cells; providing a measurement report to report at least a part of the measurements from the plurality of cells; and providing a report reporting a different number of beam information related to measured reference signals for different cells of the plurality of cells. A wireless communication network in accordance with the third aspect, e.g., network 310 comprises: a plurality of cells;

[0051] HHI - 2024P67305WO at least one user device, UE, wherein the wireless communication network is configured for configuring the UE to perform measurements of reference signals from the plurality of cells and for providing a measurement report or joint measurement report to report the measurements from the plurality of cells with a different number of reference signals for different cells of the plurality of cells. A method for operating such a wireless communication network is disclosed, the method comprising: operating a plurality of cells of the wireless communication network; operating at least one user device, UE, in the wireless communication network such that the wireless communication network configures the UE to perform measurements of reference signals from the plurality of cells and for providing a measurement report to report the measurements from the plurality of cells with a different number of reference signals for different cells of the plurality of cells. Fourth aspect Embodiments of the fourth aspect of the present invention are now described. A fourth aspect of the present invention concerns events causing a predefined action to be performed by the UE, e.g., a report to be provided and / or a conditional handover to be performed. The fourth aspect provides for advantageous considerations on how to define such events. Event Triggered LTM Event definition Layer 3 mobility utilizes Layer 3 measurement reporting, which supports UE-evaluated events for triggering measurement reports, thus reducing signaling overhead compared to periodic measurement reporting. The definition of the events for the event-triggered Layer 3 measurement report is derived from cell-level measurements. The UE conducts these

[0052] HHI - 2024P67305WO measurements, computes the cell quality using multiple measurement results from Layer 3, and then utilizes this cell quality to evaluate the event trigger criteria established for Layer 3 mobility in 3GPP TS 38.331. Although measurement reports based on beam-level results from the CSI-RS reference signal are also possible, they are not used to determine event criteria or to trigger measurement reports. However, using L1 beam measurement results may yield very unreliable predictors for the performance due to large fluctuations. Hence, in this embodiment, it is proposed establishing new L1 event criteria for event-triggered L1 measurement reports that utilize both beam-level and cell-level measurements. This means that the events will be configured based on cell quality, such as that obtained from SSB reference signal or CSI-RS measurements, and beam quality, e.g., derived from CSI-RS reference signal measurements. By incorporating both types of measurements, the system can achieve greater reliability and robustness in L1 measurements while reducing fluctuations. This approach ensures that the system benefits from both enhanced stability and reduced interruptions. The new events will enable comparisons between the radio quality of a candidate cell and the serving cell e.g., PCell, PSCell, SCell or with a predefined or dynamically configured threshold. The UE may be configured by the NW with the set of beam-performance beams and cell- performance beams. The set of cell-performance beams may be configured as a subset of the beam-performance beams. For example, the set of beam-performance beams may include narrow and wide beams, whereas the set of cell-performance beams correspond only to the wider beams. In another embodiment, the cell-performance beams may be determined explicitly, e.g., all broadcasted SSB beams of a cell are the set of cell- performance beams. The beam-level performance of a cell, e.g., serving, neighboring, SPCell, SCell, can be determined based on the best or strongest beam of the set of beam-performance beams of the associated cell. Analogously, the cell-level performance may be determined based on the best cell-performance beam. However, it's important to note that this does not ensure the candidate cell will meet the service quality requirements for the UE with its other beams after a cell switch, even if the criteria are met. For instance, meeting the event criteria with the best beam does not guarantee that the second-best beam will also satisfy the criteria since there might exist very weak beams with a large L1-RSRP difference relative to the largest measured value. This situation can result in performance degradation or ping-pong

[0053] HHI - 2024P67305WO effects, where a device repeatedly moves back and forth between two or more cells. Furthermore, this can also result in radio link failure, RLF. Therefore, several alternatives for determining the beam-level performance and cell-level performance of a cell are subject of embodiments, wherein the beam-level performance and cell-level performance may be represented by a single value or a vector of values: • Strength of strongest n beam of associated set, e.g., RSRP or SINR or RSRQ, wherein n may be configured or preconfigured, • Strength of the n-th strongest beam of the associated set, wherein n may be configured or preconfigured • Strength difference of strongest n beam of associated set and one or more reference beams, e.g., serving cell beam, weakest beam of associated set, strongest cell- performance beam, strongest beam-performance beam, wherein n is configured or preconfigured, • Mean of strongest n beams of associated set, wherein n may be configured or preconfigured, e.g., arithmetic mean, median mean, geometric mean, weighted mean, root mean square. Note that beam-level and / or cell-level performance can be confined to wideband or to one or more subbands, where a subband is located relative to the carrier frequency, and may be represented by one or more of • an offset value, • a number of subbands, • one or more subband indices, • an interlace. Note that the way to determine may be the same or different for beam-level and cell-level performance. In another embodiment, the beam-level performance and cell-level performance are combined to a single value or vector by applying one or more of the following: • Mean, e.g., arithmetic mean, median mean, geometric mean, weighted mean, root mean square, • Addition, • Max or min operation.

[0054] HHI - 2024P67305WO Furthermore, to determine the joint performance, we propose the following new L1 measurement events: Fig. 13 shows a schematic table illustrating example events 8021through 80212. One or more of those events may form an embodiment according to the fourth aspect based on the consideration with regard to the new definitions of events. Note that also different or further events might be defined and, in particular, the criteria 8041through 80412being associated with the respective event 802 may also be combined. For example, criteria 8045and 8049associated with events 8024and 8029may be combined. Any other combinations of at least two criteria, an enlarged criteria when compared to the content of Fig.13 and / or additional events may be subject of embodiments. In another embodiment, the CSI-RS and SSB may still be used to assess multiple event criteria. However, to reduce CPU usage, distinct criteria can be established for different reference signals. For instance, an initial event criterion based on the CSI-RS measurement result can be defined and executed first. If this criterion is met, a secondary criterion based on the SSB measurement is then evaluated or the other way around. This approach helps the UE conserve energy, computational power, and memory. Alternatively or in addition, event criteria for the top-n beams may be established. For instance, criteria may include a threshold value for the second strongest beam or a maximum absolute differential value between the strongest nth and (n+1)th beams that must be met prior to triggering the report. Time to Trigger for L1 measurements (TTTL1) NW has the capability to configure a TTT for each L3 event with which UE is configured. This Time to Trigger represents the duration within which specific criteria for the event must be satisfied for the UE to initiate an action, such as transmitting a measurement report to the NW or performing a cell switch. According to 3GPP TS 38.331: The IE TimeToTrigger specifies the value range used for time to trigger parameter, which concerns the time during which specific criteria for the event needs to be met in order to trigger a measurement report. Value ms0 corresponds to 0 ms and behaviour as specified in 7.1.2 applies, value ms40 corresponds to 40 ms, and so on.

[0055] HHI - 2024P67305WO In the legacy L3-event triggered reporting, UE performs L1-RSRP measurements of neighboring cells. These measurements are subsequently filtered at Layer 3 to minimize noise fluctuations and eliminate outliers. Then, the filtered measurements are reported within a RRC container. This process enables the use of more consistent data on the NW side for the handover decision-making process, but at the cost of an increased delay. Since the LTM mechanism is specifically designed to reduce handover latency and interruption times through L1 measurements, the execution of the legacy TTT mechanism may result in increased latency and decreased advantages of the LTM. Consequently, our invention introduces a novel TTT mechanism specifically tailored for L1 measurements. In our embodiment, we propose novel reset or leave conditions for a lower latency event- triggered L1 beam measurement reporting mechanism. For instance, because the event criteria will be assessed based on L1 measurements, there will be greater fluctuations compared to L3 measurements. Therefore, the evaluation criteria for the L3-RSRP of candidate cells and the serving cell need to be modified. The events may be triggered based on the beam-level and / or cell-level performance, as discussed in the previous section. In one embodiment, there may be some configured or preconfigured exceptions for the L1- TTT leaving conditions characterized by one or more of the following: • The event or one or more certain criteria of the event are not fulfilled for at most n times or at most a certain duration, wherein n and / or the certain duration may be configured or preconfigured, • UEs may be configured with multiple threshold values, such as a secondary threshold that is below or above the first threshold, wherein certain exceptions are allowed for the first threshold but not for the second threshold, • defining multiple handover trigger quantities simultaneously, such as RSRP and SINR. In the first exception, we can implement specific timer reset conditions rather than resetting the timer each time the event criteria is not satisfied. For example, a dynamic parameter k can be defined such that if the event criteria are not met k times after the timer is initiated, the timer should be restarted. This mechanism ensures that the system is not adversely

[0056] HHI - 2024P67305WO affected by every variation in the radio channel, thereby enhancing its robustness. The reset condition of the timer can be configured differently for each UE or group of UEs. Fig.14 shows a schematic diagram of a measurement value 902, e.g., RSRP or RSRQ or a different value that is monitored over time, e.g., at certain instances of time. A first threshold TH1may be defined and a lower second threshold TH2may be defined. Note that the first and the second threshold being higher or lower when compared to the other may be arbitrarily implemented with respect to the respective threshold and the acceptable values thereof. For example, in view of a delay or the like, the second threshold may be higher when compared to the first threshold. Whilst the second threshold may be considered as restarting the monitoring interval of time, e.g., when the measurement value 902 falls below the second threshold for a specified number of times, e.g., a first time, a second time, a fifth time or the like, the first threshold may allow for a higher number of times. That is, the UE may allow for an exception with regard to restarting the timer. When the event criteria is not met, e.g., the measurement value 902 falling below threshold TH1or TH2, the timer may be restarted whilst a first number of drops below threshold TH1may be allowed as an exception and a lower second number of drops below threshold TH2may be allowed. That is, the UE may be configured for restarting a timer for resetting the monitoring interval when the monitored condition, e.g., measurement value 902, fails to comply with the second threshold TH2, e.g., a first time, a second time or a predefined other time. In the second exception, the UE may be configured with two distinct thresholds, where the secondary threshold may be lower than the primary one. If the L1-RSRP or L1-RSRQ measurement falls below the primary threshold, the UE will continue to collect and observe the measurement results. However, if the L1-RSRP value drops below the secondary threshold, the UE may restart the timer. In an alternative embodiment, exceptions may be defined differently for cell-level and beam- level measurements. For instance, reset conditions may be more flexible for cell-level measurements. In another example, the primary and / or secondary thresholds for beam- level measurements may be more stringent such as having a higher threshold value compared to that of cell-level measurements. Moreover, UE may be configured with varying time-to-trigger durations for cell and beam-level measurements.

[0057] HHI - 2024P67305WO In a further embodiment, UE may utilize the filtered L1 measurements, and if the event criteria are satisfied for the specified TTT duration, the UE may transmit the unfiltered L1 measurement results instead of the filtered measurement results. Including the actual measurement results in the report provides the NW with enhanced insight into the radio conditions, thereby improving handover performance, such as reducing handover delays or mitigating radio link failure. In an alternate embodiment, we propose a minimum interval between consecutive reports. If the NW does not respond to the report transmitted by the UE, the UE will send the same or a different report only after the specified interval. This interval represents the minimum time required for the transmission of successive reports. This enhancement mitigates the frequency of report transmissions and reduces associated overhead. In another alternative embodiment, in addition to or as an alternative to establishing a minimum interval between consecutive reports, a minimum waiting period may be defined prior to the submission of the initial report to the NW after the UE has been configured. The minimum interval after the UE is configured, as well as the minimum interval between consecutive reports, can be configured and be seen in Fig.15. Fig. 15 shows a schematic time flow of a configuration 910 being received by a UE according to an embodiment, e.g., the CSI CONF. A CSI reporting may be part of a report 5101and / or 5102or a different report as described herein. According to one embodiment, a first report 5101is transmitted at time T1that is spaced from time T0at which the configuration 910 is received by at least a minimum reporting interval Δt0. Alternatively or in addition, a minimum reporting interval Δt is arranged between two or more, e.g., every adjacent or subsequent reports 5101, 5102. This allows to prevent an excessive number of reports to be transmitted in an unstable environment when the event is triggered for a large amount of times. A user device, UE, for a wireless communication network according to a first sub-aspect of the fourth aspect, e.g., UE 400, is to perform a first set of measurements of cell-strength reference signals of a cell and to perform a second set of measurements of beam-strength reference signals of the cell;

[0058] HHI - 2024P67305WO wherein the UE is to determine an event based on the first and second sets of measurements and responsive to the event, is to perform a configured or preconfigured action. According to an embodiment, the configured or preconfigured action comprises providing a measurement report, such as a Layer1 measurement report or LTM report, relating to at least one of the first and second sets of measurements; and / or performing a conditional handover procedure conditioned to the event. According to an embodiment, the first set of measurements comprises at least one measurement of a SSB reference signal and the second set of measurements comprises at least one measurement of a channel state information reference signal, CSI-RS, and / or at least one measurement of a SSB reference signal. According to an embodiment,the UE is to determine the event based on a criterion related to a radio quality of a cell serving the UE and / or a neighbouring cell. According to an embodiment, the first set of measurements is a subset of the second set of measurements. According to an embodiment, the UE is configured for determining a beam-level performance of a cell, e.g., serving, neighboring, SPCell, SCell, based on a best or strongest measurement of a beam of the second set of measurements; and / or wherein the UE is configured for determining a cell-level performance based on a best or strongest measurement of a beam of the first set of measurements. According to an embodiment, the UE is configured for determining a beam-level performance or a cell-level performance of a cell based on or as at least one of: • a strength of strongest n beam measurements of the corresponding set of measurements, e.g., RSRP or SINR or RSRQ, wherein n may be configured or preconfigured, n > 0, • a strength of the n-th strongest beam of the corresponding set of measurements, wherein n may be configured or preconfigured, n > 0

[0059] HHI - 2024P67305WO • a strength difference of strongest n beam measurements of the corresponding set of measurements and one or more reference beam measurements, e.g., serving cell beam, weakest beam of associated set, strongest cell-performance beam, strongest beam-performance beam, wherein n is configured or preconfigured and n > 0, • a mean value of strongest n beam measurements of the corresponding set of measurements, wherein n may be configured or preconfigured, e.g., arithmetic mean, median mean, geometric mean, weighted mean, root mean square, n > 0. According to an embodiment, the UE is adapted for combining a beam-level performance and a cell-level performance to a combined result, e.g., a single value or vector, by applying one or more of the following: • Mean, e.g., arithmetic mean, median mean, geometric mean, weighted mean, root mean square, • Addition, • Max or min operation. According to an embodiment, the cell is a neighboring cell or a serving cell, e.g., of the UE. According to an embodiment, the event is one of or a combination of at least two of: Event B1 The cell-level performance of serving cell exceeds a threshold value m, and the beam-level performance of serving cell exceeds a threshold value n (where m>n, m<n or m=n) Event B2 The cell-level performance of the serving cell exceeds a threshold value m, while the beam-level performance of the serving cell falls below a threshold value n (where m>n, m<n or m=n) Event B3 The cell-level performance of the serving cell falls below a threshold value m, while the beam-level performance of the serving cell falls below a threshold value n (where m>n, m<n or m=n) Event B4 The cell-level performance of the serving cell falls below a threshold value m, and the beam-level performance of the serving cell exceeds a threshold value n (where m>n, m<n or m=n) Event B5 The cell-level performance of the neighboring cell exceeds a threshold value m, and the beam-level performance of the neighboring cell exceeds a threshold value n (where m>n, m<n or m=n) Event B6 The cell-level performance of the neighboring cell exceeds a threshold value m, while the beam-level performance of the neighboring cell falls below a threshold value n (where m>n, m<n or m=n)

According to an embodiment, the UE is adapted to assess the first and second event criteria in a certain order, e.g., an initial event criterion based on a CSI-RS measurement result can be defined and executed first and if this criterion is met, a secondary criterion based on the SSB measurement is then evaluated or the other way around. According to an embodiment, the UE is adapted for assessing an event criteria for a subset of measured reference signals, e.g., having a highest ranking, e.g., in view of signal strength, e.g., considering a threshold value for the second strongest beam or a maximum absolute differential value between the strongest n-th and (n+1)-th beams that is to be met prior to triggering the configured or preconfigured action. A method for operating such a user device, UE, in a wireless communication network comprises: performing a first set of measurements of cell-strength reference signals of a cell;

[0061] HHI - 2024P67305WO performing a second set of measurements of beam-strength reference signals of the cell; determining an event based on the first and second sets of measurements and responsive to the event, is to perform a configured or preconfigured action. According to an embodiment, a wireless communication network in accordance with the fist sub-aspect of the fourth aspect, e.g., network 310, comprises: a plurality of cells; at least one user device, UE, wherein the wireless communication network is configured for configuring the UE with a set of beam-performance beams and a set of cell-performance beams. According to an embodiment, the set of cell-performance beams is configured as a subset of the beam-performance beams; or wherein the cell-performance beams is determined explicitly, e.g., all broadcasted SSB beams of a cell are the set of cell-performance beams. A method for operating such a wireless communication network comprises: operating a plurality of cells of the wireless communication network; operating at least one user device, UE, in the wireless communication network such that the wireless communication network configures the UE with a set of beam- performance beams and a set of cell-performance beams. A user device, UE, for a wireless communication network, in accordance with a second sub- aspect of the fourth aspect, e.g., UE 400 is provided, wherein the UE is to evaluate whether an event criteria relating to an event is met for a monitoring interval of time; to determine an event triggering of a configured or preconfigured action to be executed by the UE; and

[0062] HHI - 2024P67305WO wherein the UE is to reset the evaluation when the event criteria is not met during the monitoring interval except for certain exceptions; and wherein the UE is to perform the configured or preconfigured action based on the event. According to an embodiment, the event criteria is determined based on a layer1 measurement. According to an embodiment, the configured or preconfigured action comprises providing a measurement report such as a Layer1 measurement report or LTM, e.g., relating to a cell- based measurement or a beam-based measurement, and relating to the event criteria; and / or initiating a handover procedure conditioned to the event. According to an embodiment, the certain exceptions relates to one or more of: • the event or one or more certain criteria of the event are not fulfilled for at most n times or at most a certain duration, wherein n and / or the certain duration may be configured or preconfigured, • applying multiple threshold values, such as a secondary threshold, e.g., that is below or above a first threshold, wherein certain exceptions or numbers thereof are accepted by the UE for the first threshold but not for the second threshold; • defining multiple handover trigger quantities simultaneously, such as RSRP and SINR. According to an embodiment, a first exception relates to a specific timer reset condition, e.g., relating to a static or dynamic parameter k; wherein if the event criteria is not met according to the timer reset condition, the UE is to restart the monitoring. According to an embodiment, a second exception relates to multiple threshold; wherein the UE is configured with at least two distinct thresholds, wherein a monitoring condition of the event failing to comply with a first threshold leads the UE to continue monitoring as long as an exception criterion is met, e.g., a number of times or a time failing to meet the first threshold; wherein the UE is configured for restarting a timer for resetting the monitoring interval when the monitored condition fails to comply the second threshold. According to an embodiment, the UE is to implement a preconfigured or configured time interval between two subsequent events.

[0063] HHI - 2024P67305WO According to an embodiment, the UE is adapted to perform a subsequent predefined action, e.g., sending a report, only after the time interval. According to an embodiment, the UE is to implement a preconfigured or configured delay time interval between a configuration of the monitoring conditions and a first event. A method for operating such a user device, UE, in a wireless communication network comprises: evaluating whether an event criteria relating to an event is met for a monitoring interval of time; determining an event triggering of a configured or preconfigured action to be executed by the UE; resetting the evaluation when the event criteria is not met during the monitoring interval except for certain exceptions; and performing the configured or preconfigured action based on the event. A wireless communication network according to the second sub-aspect of the fourth aspect, e.g., network 310, comprises: at least one cell; a plurality of user device, UEs, wherein the wireless communication network is configured for configuring a reset condition differently for each UE or groups of UEs; wherein the reset condition relates to a reset or restart of a monitoring time interval where the UE is to evaluate an event criteria relating to an event is met; to determine an event triggering a configured or preconfigured action e.g., sending a report or initiating a handover procedure to be executed by the UE.

Fifth Aspect A fifth aspect relates to enhance event-triggered reporting by using layer1 / L1 measurements. This allows to use the low latency of layer 1 procedures and benefits from the inventive concepts of making them more robust. Current L1 and L3 events have several limitations that are addressed by embodiments, e.g., relating to the fourth aspect or embodiments related to advanced events. In the legacy L3-event triggered reporting, UE performs L1-RSRP measurements of neighboring cells. These measurements are subsequently filtered at Layer 3 to minimize noise fluctuations and eliminate outliers. Then, the filtered measurements are reported within a RRC container. This process enables the use of more consistent data on the NW side for the handover decision-making process, but at the cost of an increased delay. Since the LTM mechanism is specifically designed to reduce handover latency and interruption times through L1 measurements, the execution of the legacy TTT mechanism may result in increased latency and decreased advantages of the LTM. However, L1 measurements come at the cost of higher fluctuations. In embodiments according to the fifth aspect the L1 measurements are filtered to make them more robust.

[0065] HHI - 2024P67305WO In a further embodiment only values within a certain timeframe are considered, i.e., values before and / or after the timeframe may be ignored. In a further embodiment only the last m values are considered, i.e., from a set of measurements only a subset of last values is considered. In a further embodiment the filter removes the n (n = 1 or more) lowest or highest values, e.g., according to a criterion, and then takes the latest remaining value. In a further embodiment the filter removes the n (n = 1 or more) lowest values and then takes an average or median over the remaining values. In a further embodiment the filter removes the n (n = 1 or more) highest values and then takes an average or median over the remaining values. In a further embodiment the filter removes the n (n = 1 or more) highest values and then takes the highest remaining value. In a further embodiment the filter uses a time weighted average. Those are examples of a selection of measurements used for determining an event. A user device, UE, for a wireless communication network according to the fifth aspect such as UE 400 is to perform measurements of reference signals of a cell. The UE is to process the measurements; and to determine an event based on the processed measurements and responsive to the event, is to perform a configured or preconfigured action. According to an embodiment, the UE is adapted to filter the measurements to process the measurements, e.g., using a time weighted average, an arithmetic mean, median mean, geometric mean, weighted mean, root mean square. According to an embodiment, processing the measurements comprises selecting only measurement values from a certain timeframe for determining the event. According to an embodiment, processing the measurements comprises considering a certain number of last m values as a subset of the measurements for determining the event.

[0066] HHI - 2024P67305WO According to an embodiment, processing the measurements comprises removing a number of at least one lowest or highest measurement values and using remaining values, e.g., a latest remaining value, for determining the event. According to an embodiment, processing the measurements comprises removing at least one lowest values and then taking an average or median over remaining values for determining the event. According to an embodiment, processing the measurements comprises removing at least one highest values and then taking an average or median over remaining values for determining the event. According to an embodiment, processing the measurements comprises removing at least one highest value and then taking the highest remaining value for determining the event. A method for operating such a user device, UE, in a wireless communication network comprises: performing measurements of reference signals of a cell; processing the measurements; and determining an event based on the processed measurements and responsive to the event, is to perform a configured or preconfigured action. Sixth Aspect A sixth aspect of the present invention concerns conditional LTM and / or conditional handover. In the context of CHO in 3GPP TS 38.300, UE maintains its connection with the source gNB upon receiving the CHO configuration and initiates the evaluation of the CHO execution conditions for the candidate cell(s). If at least one candidate cell meets the specified CHO execution condition, the UE detaches from the source gNB, applies the stored configuration corresponding to the selected candidate cell, synchronizes to that candidate cell, and

[0067] HHI - 2024P67305WO finalizes the RRC handover procedure by transmitting the RRCReconfigurationComplete message to the target gNB. This concept can also be adapted for the LTM framework. The UE can be configured with sets of handover conditions and perform certain L1 measurements. If at least one candidate cell meets the corresponding handover condition, the UE will execute the handover. However, rather than utilizing RRC signaling to send the complete message to the NW, we propose that the UE 400 may convey the handover complete message 922 to the gNB 406 through L1 / L2 signaling as shown in Fig.16. Additionally, the embodiments of this invention described for event triggered LTM above can also be applied to LTM-CHO. The only difference is that when the event is triggered, the UE will autonomously make the handover decision instead of sending a measurement report to the NW.
