Description

[0001] CELL DETECTION AND MEASUREMENTS

[0002] FIELD

[0003] Various example embodiments relate to the field of wireless communication and, in particular to cell detection and / or cell measurements for cell detection.

[0004] BACKGROUND

[0005] In the field of wireless communication, mobility management concept(s) exist which include mobility procedures, such as for example Lower Layer Triggered Mobility (LTM) or Layer 1 (L1) / Layer2 (L2) Triggered Mobility. These may include a cell transitions or switch procedures, in particular where an apparatus', e.g. a User Equipment's (UE), serving cell may be changed or switched, e.g. to a candidate cell or target cell. Mobility procedures, such as LTM, may include or define requirements of the apparatus, e.g. the UE, to, in particular when and / or how, to perform cell measurements and / or measurement reporting. However, it may be beneficial, e.g. among other things, to optimize performing of cell measurements and / or reporting, in particular to reduce and / or minimize overhead and / or energy consumption, e.g. to save energy, for the apparatus, e.g. the UE, and / or to reduce and / or minimize a number of measurements and / or a time period for performing measurements, in particular for mobility procedures.

[0314] Reference will now be made in detail to the various embodiments, one or more examples of which are illustrated in the figures. Within the following description of the drawings, the same reference numbers may refer to same components. Generally, only the differences with respect to individual embodiments may be described. Each example may be provided by way of explanation and is not meant as a limitation. Further, features illustrated or described as part of one embodiment can be used on or in conjunction with other embodiments to yield yet a further embodiment. It is intended that the description includes such modifications and variations.

[0315] The drawings are schematic drawings which are not drawn to scale. Some elements in the drawings may have dimensions which are exaggerated for the purpose of highlighting aspects of the present disclosure and / or for the sake of clarity of presentation.

[0316] A "mobility procedure" may be regarded as or may refer to a process of transitioning an apparatus, in particular a User Equipment (UE), from one network entity (e.g. a cell, beam, transmission reception point, or access point) to another network entity, in particular to maintain seamless connectivity. Mobility may be to ensure communication as users move across different coverage areas. It may prevent call drops and / or data session interruptions. Mobility procedures may also be referred to as cell transition / switch procedures. Non-limiting examples for mobility procedures are handovers (HO), which may occur in a higher layer(s), e.g. Layer 3 (L3) and / or cell switches, which may occur in lower layers, e.g. Layer 1 (L1) / Layer 2 (L2). "Lower Layer Triggered Mobility” "(LTM) or "Layer 1 (L1) / Layer2 (L2) Triggered Mobility" may refer to a particular mobility procedure, e.g. initiated in a cellular network based on events and / or measurements detected at lower layers of a protocol stack - for example, a physical layer or Layer 1 and / or a data link layer or Layer 2 or MAC layer etc. LTM may provide mechanisms, e.g. for a network node and User Equipment (UE), to address mobility needs, complementing, e.g., higher-layer (e.g. Layer 3 or Radio Resource Control (RRC)) mobility processes.Mobility procedures, e.g. as exemplarily mentioned above, may have associated measurement(s) and / or reporting and, in particular consequent triggered mobility based on such measurement(s) and / or reporting. These measurements may include at least one beamlevel measurement and / or at least one cell-level measurement. The reporting may include at least one beam-level reporting and / or at least one cell-level reporting.

[0317] A "beam-level measurement" may be an evaluation and / or measurement of, in particular individual, transmission beam(s), e.g. within / which belong to a given cell. These measurements help to determine a beam quality and / or to decide whether a cell switch is needed. A beamlevel measurement may provide detailed information about, e.g. beam quality and / or may assist in selecting the best beam for data transmission. A beam-level measurement may be used for beam management, such as beam selection, beam switching, beam refinement etc. A "beam" or "at least one beam" may be used interchangeably herein with at least one Reference Signal (RS) and / or may be considered as a, in particular focused, transmission of, e.g. radio, signals, including for example, reference signals which may be transmitted using Multiple-Input Multiple-Output (MIMO) and / or beamforming techniques. Beams can have various characteristics and serve different purposes based on their configuration and use case. The at least one beam may include one or more beams or one or more beam pairs, e.g. such as a first beam and a second beam, which may be received from the same or different sources, e.g. cells. For example, there may be a first beam from a first cell, e.g. a serving cell, and a second beam from a second cell, e.g. a candidate or target cell or even another serving cell. Beams may be characterized by different properties, including for example signal strength or power, which may indicate how strong a signal transmitted by the beam is, in particular at the receiver, e.g. the UE. This may be for example measured as Reference Signal Received Power (RSRP), e.g. an average received power of the reference signals, or Reference Signal Strength Indicator (RSSI), e.g. a total received power including noise and / or interference. Stronger signals may indicate better connectivity. Beams may also be characterized by signal quality, e.g. how "clean" the signal is, considering interference and / or noise. This may be for example measured as Reference Signal Received Quality (RSRQ), e.g. a ratio of RSRP to RSSI, indicating interference levels and / or Signal-to-lnterference-plus-Noise Ratio (SI NR), e.g. a ratio of the desired signal power to interference and / or noise power. Other properties and / or metrics are conceivable. A beam level measurement may be referred to as L1 measurement or LTM measurement.A non-limiting example in the context of LTM for a beam-level measurement may be a Layer 1 (L1) measurement, e.g. the at least one beam-level measurement may be a Layer 1 (L1) measurement or LTM measurement. L1 (Layer 1) measurement(s) may include physical-layer measurement(s) to evaluate radio conditions. These measurements may involve assessing signal strength, quality, and / or other parameters, e.g. of reference signal(s) transmitted by a network node, e.g. using one or more beams. L1 measurements may be used for mobility management, such as handovers / cell switches, beam management, and / or connection reestablishments. In order to select appropriate candidate cells and / or beams, e.g. for early uplink and / or downlink synchronization and / or cell switching in LTM, both intra-frequency L1 measurements and / or inter-frequency L1 measurements, e.g. using synchronization signal block (SSB) transmissions from the candidate cells, may be supported and / or utilized. A LTM cell switch-decision may be based on measurements (for example beam-level or L1 measurements, or cell-level or L3 measurements) that may be performed and / or reported (for example via a corresponding beam-level or L1 measurement report(s), or cell-level or L3 measurement report(s)), e.g. by the UE. "Uplink (UL) synchronization" may refer to a process where the apparatus, e.g. the UE, aligns its transmission timing with the network's expectations, e.g. to ensure proper communication. In other words, the apparatus, e.g. the UE, may transmit its signals at a correct timing, e.g. so they reach the network without collisions or interference. "Downlink (DL) synchronization" may refer to a process where the apparatus, e.g. the UE, aligns itself with timing and / or frequency of a downlink signal from the network. DL synchronization may ensure that the apparatus, e.g. the UE, can correctly receive and / or interpret signals from the network. "Early" synchronization may refer to initiating and / or performing at least one of: UL or DL synchronization, in particular before the actual execution of a cell switch / change procedure. Intra-frequency L1 measurements may refer to measurements performed on reference signals, e.g. transmitted on a same carrier frequency or a same active BWP as a serving cell, which may be used to, e.g. evaluate the serving cell’s signal quality. Inter-frequency L1 measurements may refer to measurements performed on reference signals, e.g. transmitted on frequencies different from the serving cell’s carrier frequency, which may be used to, e.g. evaluate the signal quality of cells or beams operating on different frequency layers, e.g., different carrier frequency or on a BWP different than the active BWP. Reference Signals used for L1 measurements may include Synchronization Signal Blocks (SSBs) or Channel State Information Reference Signals (CSI-RS)."Beam-level reporting" may be regarded as a transmission, for example by the apparatus, e.g. the UE, of at least one (measurement) report, e.g. a beam-level report, which comprises information associated with a beam-level measurement, in particular information related to the at least one beam, e.g. beam-specific information. A non-limiting example in the context of LTM for a beam-level report / reporting may be a Layer 1 (L1) report / reporting, e.g. the at least one beam-level report may be a Layer 1 (L1) report. L1 reports may be periodic (e.g., every "X" ms) or event-based (e.g., when a beam’s quality significantly changes) etc. L1 reporting may be related to the physical channel it is reported in i.e. , Physical Uplink Control Channel (PUCCH) or Physical Uplink Shared Channel (PUSCH). Similarly, L1 reporting may be related to a container the report is sent in e.g., a MAC CE report, a RRC measurement report or a CSI reporting container. When L1 measurements detect a sufficiently strong beam from a neighboring cell, a report may be sent, e.g. to trigger L3 measurements. L1 reports may be continuously generated as beam quality changes. Beam-level reporting, in particular L1 measurement reporting, may come with certain requirements and / or restrictions as outlined below.

[0318] A "cell-level measurement" may provide an, in particular aggregated, assessment of a cell's overall signal strength and / or quality, in particular rather than focusing on individual beams as for a beam-level measurement. A non-limiting example in the context of LTM for the at least one cell-level measurement may be a Layer 3 (L3) measurement, e.g. the at least one celllevel measurement may be a Layer 3 (L3) measurement. Layer 3 (L3) measurements may be used to provide higher-layer mobility management functions and / or may assist in determining whether a cell is a viable candidate for mobility, e.g. by monitoring Reference Signals (RS), such as SSB-based signals. For example, L3 measurements may correspond to L1 measurements that may be filtered at Layer 3, e.g. to remove or minimize an impact of, e.g. fast fading, in particular to reduce short term variations in measurement results. L3 measurements may correspond to averaging of multiple beam measurements corresponding to a cell. Cell level measurements may comprise detection procedure of a cell. "Cell-level reporting" may be regarded as a transmission, for example by the apparatus, e.g. the UE, of at least one (measurement) report, e.g. a cell-level report, which comprises information associated with a cell-level measurement. A non-limiting example in the context of LTM for a beam-level report / reporting may be a Layer 3 (L3) report / reporting, e.g. the at least one beamlevel report may be a Layer 1 (L1) report.A "candidate cell" (or "target cell") (these terms may be used interchangeably herein) may be referred to as a neighboring cell or one of UE’s current serving cell (e.g. SCell) that the apparatus, e.g. the UE, evaluates as a potential replacement for the current serving cell (e.g. PCell or PSCell), in particular during a mobility event. If particular conditions are met / satisfied, the UE may initiate a transition / switch process to the target cell. The "serving cell" may be the active cell currently providing network connectivity to the UE. In a non-limiting context of LTM, candidate cell(s) may be neighboring cell(s) or a UE’s current serving cells (e.g. SCells) (as mentioned above). In a non-limiting example of 5G, cell terms may be and / or may apply as follows: i) Primary cell (PCell), ii) Secondary cell (SCell), iii) Primary cell of a secondary cell group (PSCell), iv) Special cell (SpCell), which may be used to refer, in particular, commonly to a PCell or a PSCell. There may be only one special cell for each cell group. The PCell may be a, in particular primary, cell in / for a Master Cell Group (MCG) and PSCell may be a, in particular primary cell, in / for a Secondary Cell Group (SCG). Each cell group may have multiple SCells, but a unique PCell. All the cell types can be configured for a target or candidate cell. A Target Cell may be a cell to which the apparatus, e.g. the UE, is executing handover or cell change. A Serving Cell may be a cell that is, in particular currently, serving the apparatus, e.g. the UE. A Source Cell may be a cell from which the apparatus, e.g. the UE is executing the handover or cell change. A Candidate Cell may be a cell that is a candidate to become a target cell for a handover or cell change.

[0319] According to subject-matter described herein, at least one "cell acquisition procedure" for at least one candidate cell may be conducted and / or performed. Instead of cell "acquisition" procedure, it may be referred to a cell "reading" procedure, cell "assessment" procedure, or cell "determination" procedure (these terms may be used interchangeable therein) or a procedure that leads / contributes to a cell being in a known state. A cell acquisition procedure may indicate that the detection, measurement and / or acquisition process has two parts, stages, steps and / or phases, e.g. a first step to become aware of a cell, e.g. to detect the cell and a second step to identify the detected cell. For example, the at least one cell acquisition procedure may comprise:

[0320] i) an "initial cell detection procedure", in particular to detect the at least one candidate cell. This may be regarded as a first step / stage in the cell acquisition procedure. For example, the initial cell detection procedure may be conducted to detect, determine and / or become aware of at least one (candidate) cell. In other words, it may be conducted to determine / detect a presence, availability, existence and / or an exposure of / to the at least one (candidate) cell. Theinitial cell detection procedure may be conducted, for example by performing / conducting at least one cell-level measurement, in particular to detect the at least one candidate cell. After the at least one cell-level measurement, the at least one (candidate) cell may be referred to as a "detected" (candidate) cell. However, it should be noted that a "detected" (candidate) cell may be different from a "known" (candidate) cell and / or an "identified" (candidate) cell; and / or ii) a "cell identification procedure", in particular to identify the at least one (candidate) cell. This may be regarded as a second step / stage in the cell acquisition procedure, e.g. after i). The cell identification procedure may be performed for / based on at least one detected (candidate) cell. For example, the cell identification procedure may be conducted to identify, verify and / or confirm the at least detected (candidate) cell and / or to determine, retrieve and / or decode further information of the detected (candidate) cell. In one example the identification procedure may refer to obtaining the physical cell identification of the detected cell. In other words, initial detection may ensure that a cell is present, while identification may retrieve specific information to confirm the cells suitability, e.g. for further mobility related actions. However, it should be noted that i) and ii) may also be conducted independently and / or individually of each other, e.g. it may not be necessary to (always) perform a cell identification procedure after an initial cell detection procedure.

[0321] According to subject-matter described herein, at least one "requirement" may refer to a need, obligation, necessity and / or duty for the apparatus, e.g. the UE, to perform / conduct measurements and / or reporting, in particular beam-level and / or cell-level measurements and / or reporting. In other words, a "requirement" may cause, initiate, trigger, infer, demand, request and / or force a (corresponding) behavior of the apparatus, e.g. the UE. The at least one requirement may follow from and / or be specified, defined, or predetermined in standard document(s). A non-limiting example of such a requirement and / or a standard document is TS 38.133. An excerpt of a requirement, in particular a Radio Resource Measurement (RRM) requirement, is being provided in the following. However, it should be noted that the same and / or its content should be considered purely optional and / or non-limiting. A requirement (e.g. RRM requirement) in TS 38.133 may be, for example, as follows:

[0322] "9.14 Intra-frequency L1-RSRP measurements for neighbor cell

[0323] 9.14.1 Introduction

[0324] 9.14.2. Requirements Applicability

[0325] The requirements in clause 9.14 are applicable to FR1 and FR2-1 forLTM.The requirements in clause 9.14 apply, provided for the SSB from the neighbor cell configured for intra-frequency L1-RSRP measurement, the following conditions are met: - The cell is known

[0326] - The SSB configured for intra-frequency L1-RSRP measurement is on the same carrier frequency of SSB configured for L3 intra-frequency measurement.

[0327] - The SSB resources configured for L1-RSRP measurement are measurable.

[0328] An SSB resource configured for L1-RSRP for neighbor cell shall be considered measurable when for each relevant SSB, the following conditions are met:

[0329] - L1-RSRP related side conditions given in clause [10.1.19] forFRI and [10.1.20] for FR2-1, respectively, fora corresponding band,

[0332] - The SSB from the target cell configured for L1 measurement remains detectable according to the cell identification requirements in clause 9.2.

[0333] Otherwise the cell is unknown.

[0334] 9.2 NR intra-frequency measurements

[0335] 9.2.1 Introduction

[0336] A measurement is defined as a SSB based intra-frequency measurement provided the center frequency of the SSB of the serving cell and the center frequency of the SSB of the neighbor cell indicated for measurement are the same, and the subcarrier spacing of the two SSBs are also the same.

[0337] The UE shall be able to identify new intra-frequency cells and perform SS-RSRP, SS- RSRQ, and SS-SINR measurements of identified intra-frequency cells if carrier frequency information is provided by PCell or the PSCell, even if no explicit neighbor list with physical layer cell identities is provided.9.2.2 Requirements applicability

[0338] The requirements in clause 9.2 apply, provided:

[0339] The cell being identified or measured is detectable.

[0340] An intra-frequency cell shall be considered detectable when for each relevant SSB:

[0341] SS-RSRP related side conditions given in clauses 10.1.2 and 10.1.3 for FR1 and FR2, respectively, for a corresponding Band,

[0342] SS-RSRQ related side conditions given in clauses 10.1.7 and 10.1.8 for FR1 and FR2, respectively, for a corresponding Band,

[0344] SSB_RP and SSB Es / lot according to Annex B.2.2 for a corresponding Band.

[0345] From section 9.2 for example table 9.2.5.1-2 it is seen that the UE minimum requirements for PSS / SSS detection is 600ms.

[0346] 10.1.4.1.1 Absolute Accuracy of SS-RSRP in FR1

[0347] The requirements for absolute accuracy of SS-RSRP in this clause apply to a cell on a frequency in FR1 that has different carrier frequency from the serving cell. The accuracy requirements in this clause are also applicable when highSpeedMeaslnterFreq-r17 is configured.

[0348] The accuracy requirements in Table 10.1.4.1.1-1 are valid under the following conditions:

[0349] Conditions defined in clause 7.3 of TS 38.101-1

[0018] for reference sensitivity are fulfilled.

[0350] Conditions for inter-frequency measurements are fulfilled according to Annex B.2.3 fora corresponding Band for each relevant SSB.

[0351]

[0352] Table 10.1.4.1.1-1: SS-RSRP Inter frequency Absolute accuracy in FR1

[0353] Furthermore, an excerpt of a requirement, in particular an RF requirement, is being provided in the following. However, it should be noted that the same and / or its content should be considered purely optional and / or non-limiting. The requirement (e.g. RF requirement) may be specified in TS 38.101-1:

[0354] 7.3 Reference sensitivity

[0355] 7.3.1 General

[0356] The reference sensitivity power level REFSENS is the minimum mean power applied to each one of the UE antenna ports for all UE categories, at which the throughput shall meet or exceed the requirements for the specified reference measurement channel. In later clauses of Clause 7 where the value of REFSENS is used as a reference to set the corresponding requirement:

[0357] In all bands, the UE shall be verified against those requirements by applying the REFSENS value in Table 7.3.2-1 with 2 Rx antenna ports tested;for bands where the UE is required to be equipped with 4 Rx antenna ports, the UE shall additionally be verified against those requirements by applying the resulting REFSENS value derived from the requirement in Table 7.3.2-2 with 4 Rx antenna ports tested.

[0358] 7.3.2 Reference sensitivity power level

[0359] The throughput shall be > 95 % of the maximum throughput of the reference measurement channels as specified in Annexes A.2.2.2, A.2.3.2, A3.2 and A.3.3 (with one sided dynamic OCNG Pattern OP.1 FDD / TDD for the DL-signal as described in Annex A.5.1.1 / A.5.2.1) with parameters specified in Table 7.3.2-1 and Table 7.3.2-2.

[0360]

[0361] Table 7.3.2-1: Two antenna port reference sensitivity QPSK PREFSENS (reduced table with the aim to give some examples)

[0362] However, such a requirement may force the apparatus, e.g. the UE, to perform and / or conduct a (corresponding) behavior, for example performing / conducting one or more measurements, in particular beam-level measurements and / or cell-level measurements, potentially along with a corresponding reporting. The above requirements may force the apparatus to detect a cell within a given time with the given accuracy, given the above conditions are met. The following provides a non-limiting example of a requirement in existing approaches: The requirement may start with a step of beam-level or L1 measurements being configured to the apparatus, e.g. theUE. The apparatus, e.g. a UE, may perform, or has already performed, cell-level or L3 measurement(s) for a candidate cell, e.g. for which beam-level or L1 measurement(s) may be configured. If the candidate cell is detected, the apparatus, e.g. the UE, may start conducting beam-level or L1 measurement(s). In either case of it being detected or not, the apparatus, e.g. the UE, may be required / forced to perform or continue the cell-level L3 measurement. The apparatus, e.g. the UE, may also start doing beam-level or L1 measurement(s). If the candidate cell is not detectable anymore, the apparatus, e.g. the UE, may stop doing the beam-level or L1 measurement(s) and otherwise may go on with the measurement(s). However such existing approaches may result, among others, in the following issues: i) Why does the apparatus, e.g. the UE, measure the same cell with both beam-level or L1 measurement(s) and cell-level or L3 measurement(s)? and / or ii) Why does the apparatus, e.g. the UE, keep reporting the same cell through a cell-level or L3 measurement report, in particular after the apparatus, e.g. the UE, starts sending a beam-level or L1 measurement report? The subject-matter described herein intends to address these issues. In addition, the subject-matter described herein considers details about how a cell detection and / or identification procedure may impact, influence and / or affect, in particular interworking, interaction, coordination and / or cooperation, of beam-level or L1 measurement(s) and cell-level or L3 measurement(s). Detection may also have been neglected in existing procedures to this point.

[0363] According to subject-matter described herein, requirement to perform a beam-level measurement or a cell-level measurement, for at least one candidate cell is suspendable, in particular at least temporarily. For example, the requirement may be deactivated, turned-off, paused, halted, disabled, suspended and / or stopped (which may be referred to as a first state / mode of the requirement). Likewise, the requirement may be activated, turned-on, continued, enabled, resumed and / or initiated (which may be referred to as a second state / mode of the requirement). As such, the requirement may be i) controllable, ii) switchable, iii) configurable iv) changeable, v) adjustable and / or vi) selectable, in particular between the first state / mode of the requirement and the second state / mode of the requirement, or vice versa. This may be done at least once, or multiple times. This may also be referred to as an adaptive suspension. The aforementioned terms may be used interchangeably herein. For example, i) the at least one beam-level measurement or ii) the at least one cell-level measurement as mentioned herein may be, in particular at least temporarily suspended. As such, it may be switched, at least once, between performing / conducting the at least one beam-level measurement and performing / conducting the at least one cell-level measurement or vice versa.As an example, one of: i) the at least one beam-level measurement or ii) the at least one celllevel measurement may be suspendable on the at least one candidate cell, while another one of: i) the at least one beam-level measurement or ii) the at least one cell-level measurement may be executable and / or reportable on the, in particular same, at least one candidate cell.

[0364] However, the ability to determine whether to perform / conduct or at least temporarily suspend: i) at least one beam-level measurement or ii) at least one cell-level measurement (and / or to at least temporarily suspend a requirement to perform / conduct the same, e.g. i) or ii)) may provide significant advantages, in particular in terms of energy efficiency, measurement accuracy, and / or operational flexibility. For example, a UE that is not required to perform beam-level, e.g. L1, or cell-level, e.g. L3, measurements at a given moment can turn off these measurements, e.g. to conserve battery power. By, in particular selectively, disabling / suspending measurement functions, the UE may extend battery life. While turning-off / suspending measurements may save energy, there may be cases where the UE might continue beam-level, e.g. L1, or celllevel, e.g. L3, measurements, e.g. even when not explicitly required. This approach may enhance accuracy, e.g. when the measurements are eventually needed. For example, continued beam-level, e.g. L1, or cell-level, e.g. L3, measurements may allow the UE to maintain up-to-date information. In some cases, even if a UE is not required to perform celllevel, e.g. L3, measurements from a radio perspective, it may still be triggered by an application or operator command to perform them.

[0365] A "measurement configuration" may refer to the set of parameters and / or rules that define how the apparatus, e.g. the UE, may conduct or perform one or more measurement(s). A measurement configuration may be provided by the network and / or specify which frequency to measure, what signals, e.g. reference signals, to measure and / or how often / frequent the measurement(s) should be taken and / or under what conditions they should be reported back to the network. A measurement configuration may include at least one "measurement object", which may specify and / or define the object, element, signal, carrier frequency, cell, entity, measurement window, resource block and / or channel to be measured, in particular what the UE should measure, such as, e.g. at least one signal, e.g. Channel State Information (CSI) Reference Signal (RS), a Synchronization Signal Block (SSB), a SSB-based Synchronization Signal or the like. A measurement configuration may define and / or include a measurement periodicity, e.g. how frequent measurements are to be carried out.The measurement configuration may include a first measurement configuration, in particular a measurement configuration for the at least one beam-level measurement, which may also be referred to as beam-level measurement configuration. The measurement configuration for the at least one beam-level measurement may be a L1 measurement configuration and / or it may include or indicate at least one measurement object, e.g. at least one measurement object for the at least one beam-level measurement. A L1 measurement configuration may be referred to as CSI measurement configuration. A L1 measurement object may be referred to as CSI resource configuration. In addition or alternatively thereto, the measurement configuration may include a second measurement configuration, in particular a measurement configuration for the at least one cell-level measurement, which may also be referred to as cell-level measurement configuration. The measurement configuration for the at least one cell-level measurement may be a L3 measurement configuration and / or it may include or indicate at least one measurement object, e.g. at least one measurement object for the at least one cell-level measurement. The measurement configuration, in particular both the measurement configuration for the at least one beam-level measurement and the measurement configuration for the at least one cell-level measurement, may be provided to the apparatus, e.g. the UE, concurrently, in parallel, simultaneously and / or at the same time, for example in / using at least one message. The at least one message may be received before initiation of the at least one cell acquisition procedure for the at least one candidate cell. Providing the apparatus, e.g. the UE, with the measurement configuration may be referred to as "configuring" the apparatus, e.g. the UE.

[0366] According to subject-matter described herein, the apparatus, e.g. the UE, may receive at least one indication. The indication may be at least one indication (or more), or the indication may correspond to a single indication having multiple parts. In other words, there may be a first indication or at least a first part of the indication indicating a first information, and a second indication or second part of the indication indicating a second information. Thus, when reference to an "indication" is made, (only) a "part" of the indication may be meant. The at least one indication, e.g. the first information and / or the second information, may indicate one or more characteristic, feature, part and / or property related to a) the requirement described herein, and / or b) to the at least one beam-level / cell-level -measurement, -measurement configuration and / or -reporting etc., in particular which is described herein. For example, the at least one indication may indicate that a requirement to perform i) a beam-level measurement or ii) a cell-level measurement, for at least one candidate cell, is suspendable as mentioned. However, the indication may, in addition or alternatively, indicate other features, for examplean ability to switch between the requirement to perform beam-level measurements and the requirement to perform cell-level measurements etc. The indication may be an explicit indication, e.g. (directly) included or encoded in a message, e.g. directly readable by the apparatus, or included in a measurement configuration. The indication may be a flag which is included or encoded in the message or the measurement configuration, e.g. using at least one Information Element (IE) and / or one or more bit(s). However, the indication may also be received separately and / or independently of the measurement configuration or the message. The indication may also be an implicit indication, e.g. derivable from the message or the measurement configuration itself, e.g. the UE, may conclude to the indication based at least in part on the message orthe measurement configuration, "based at least in part on the indication" may, for example, mean based on one or more part(s) of the indication. In other cases, it may mean, for example, based on the indication, e.g. as a whole, but also based on additional information and / or additional information element(s), parameters or data. The implicit indication derived from the measurement configuration can be done through matching the reference signals to be measured by beam-level or L1 and cell-level or L3 measurement configuration and, e.g. determining that these two objects are associated with each other. After such an association the UE can conclude that the procedures described herein shall be applied.

[0367] The indication may indicate that the at least one beam-level measurement and the at least one cell-level measurement are to be performed hierarchically. For example, this may mean that the at least one beam-level measurement and the at least one cell-level measurement are to be conducted in a structured way or order, e.g. stepwise, for example, first or in a first step, the at least one beam-level measurement may be performed / suspended and secondly, in a second step, the at least one cell-level measurement may be performed / suspended, or vice versa.

[0368] The measurement configuration for the at least one cell-level measurement of the at least one candidate cell may be a periodic measurement configuration. For example, this may indicate that the at least one cell-level measurement is to be performed, conducted, triggered and / or initiated periodically, e.g. at regular (time) intervals etc. This type of configuration may be used to balance measurement accuracy and / or energy efficiency, in particular as this may ensure that the UE collects and / or reports measurement data (only) at predefined time intervals, rather than performing measurements all the time.According to subject-matter described herein, the apparatus may determine, based at least in part on the at least one indication, whether to at least temporarily suspend: i) at least one beamlevel measurement or ii) at least one cell-level measurement, "in association with or based on at least one cell acquisition procedure" for the at least one candidate cell. In other words, the apparatus may determine an associated action in association with / based on the i) (initial) cell detection procedure or the ii) cell identification procedure described herein. This may mean, that the apparatus, e.g. the UE, may make a decision based on / taking into account the respective cell acquisition procedure, because, for example, once a cell has been (sufficiently) detected or identified, certain measurements (either beam-level or cell-level) might no longer be necessary for a period of time. Thus, the cell acquisition procedure may directly influence, affect and / or dictate necessity of certain measurements. In particular, the apparatus, e.g. the UE, may dynamically adjust its beam-level or cell-level measurements, e.g. based on where it is in the cell acquisition process. If a cell has been detected or identified, there may be no need to keep performing unnecessary measurements, which may result in saving battery power. The apparatus, e.g. the UE, may focus its processing power on (other) relevant tasks, making, e.g. cell switches / handovers, and / or beam switching more efficient. Instead of measuring all the time, the apparatus, e.g. the UE, may optimize when and what it measures, which may reduce computational and / or signaling load.

[0369] Based on determining, whether to at least temporarily suspend: at least one beam-level measurement or a at least one cell-level measurement, the apparatus, e.g. the UE, may i) perform / conduct the at least one cell-level measurement; ii) suspend / deactivate the at least one cell-level measurement; iii) perform / conduct the at least one beam-level measurement and / or iv) suspend the at least one beam-level measurement. In particular, the at least one celllevel measurement may be suspendable / suspended in dependence of the at least one beamlevel measurement, or vice versa. The steps i)-iv) may be carried out, for example based at least in part on i) the indication and / or ii) the measurement configuration (or the respective message), in particular based on the measurement configuration for at least one beam-level measurement and the measurement configuration for at least one cell-level measurement, as described herein. Furthermore, one of the at least one beam-level measurement or the at least one cell-level measurement may be suspendable / suspended on the at least one candidate cell, while another one of the at least one beam-level measurement or the at least one cell-level measurement may be executable / executed and / or reportable / reported on the same at least one candidate cell. The respective measurement that is to be suspended may be / correspondto a measurement defined by the requirement described herein. These approaches may optimize energy consumption by avoiding unnecessary measurements and / or allow to prioritize relevant measurements, e.g. based on the mobility situation of the UE. Under "performing / conducting" a particular measurement, it may be understood, in performing / conducting an initial measurement, e.g. to initiate, trigger and / or start a measurement for the first time, initially, or it may mean to continue, resume and / or restart an (earlier) measurement, which was for example suspended, paused, halted and / or stopped, e.g. at least temporarily.

[0370] The measurement configuration for at least one beam-level measurement and the measurement configuration for at least one cell-level measurement may be associated with one another. For example, they may be linked, related, coupled, paired, interconnected, dependent and / or coordinated from / with one another. This may mean that the apparatus, e.g. the UE, may treat beam-level measurement(s) and cell-level measurement(s) dependently of each other, e.g. instead of unrelatedly enabling / disabling measurements. The measurement configuration for the at least one beam-level measurement and the measurement configuration for at least one cell-level measurement may be explicitly or implicitly associated or linked with one another. For example, the measurement configuration may include an (explicit) indication, which (explicitly) associates them with one another (or it may be indicated by using at least one part of the indication). For example, the indication may, e.g. explicitly, link the at least one beam-level measurement to at least one measurement object, e.g. included in the measurement configuration for at least one cell-level measurement. This may be achieved by using at least one identifier (ID), wherein in particularthe at least one indication may correspond to the ID. The ID may be included in or associated with ortagged / assigned to the at least one measurement object, e.g. of the measurement configuration for at least one cell-level measurement. In another example, the measurement configuration may include an (implicit) indication, which (implicitly) associates them with one another. For example, the indication may, e.g. implicitly, link the at least one beam-level measurement to at least one measurement object, e.g. included in the measurement configuration for at least one cell-level measurement. The at least one indication may be derivable based on a (common) carrier frequency of at least one of: the at least one beam-level measurement and the at least one cell-level measurement, or - at least one measurement object indicated in the measurement configuration for at least one beam-level measurement and at least one measurement object indicated in the measurement configuration for at least one cell-level measurement. This may allow or enablethe apparatus, e.g. the UE, to make coordinated decisions / measurements, rather than treating them as separate processes, which may enhance energy efficiency, reduce UE processing load, and improve network performance.

[0371] The apparatus, e.g. the UE, may determine whether (and / or when) to trigger at least one beamlevel measurement based on the association and / or linkage between the measurement configuration for at least one beam-level measurement and the measurement configuration for at least one cell-level measurement. To do so, the apparatus, e.g. the UE, may assess, access and / or check the measurement configuration. The apparatus, e.g. the UE, may assess a number of / check how many measurement objects for the at least one beam-level measurement may be associated or linked with at least one measurement object for the at least one cell-level measurement. This may be done differently, e.g. depending on the type of indication, e.g. explicit or implicit indication, used. For example, this may be achieved by checking, examining, inspecting or determining if an ID is / has been assigned to the at least one measurement object for the at least one cell-level measurement. As mentioned above, the ID may explicitly link these, so that the apparatus, e.g. the UE, may simply read, extract and / or gather the ID, e.g. to determine the number of associated / linked measurement objects. In another example, the apparatus, e.g. the UE, may check, compare and / or analyze at least one carrier frequency of the measurement object for the at least one beam-level measurement and at least one carrier frequency of the at least one measurement object for the at least one cell-level measurement. If the carrier frequencies match or are shared, the apparatus, e.g. the UE, may derive, deduce and / or conclude to an association / linkage between them. The apparatus, e.g. the UE, may repeat this process for other measurement objects, in particular the measurement object for the at least one beam-level measurement and the at least one measurement object for the at least one cell-level measurement, to determine how many are associated with one another. Based on this assessment, the apparatus, e.g. the UE, may suspend at least one cell-level measurement. For example, if (only) a single measurement object is associated with the measurement object for the at least one cell-level measurement, the UE may suspend the celllevel measurement, in particular because the UE may already have enough information, e.g. from the beam-level measurement, so that it may not need further cell-level scanning. This may reduce redundant measurements and / or optimize resource usage. For example, if multiple, a plurality or at least two measurement objects for the at least one beam-level measurement are associated with at least one, e.g. the same, measurement object for the at least one cell-level measurement, then the apparatus, e.g. the UE, may check for (currently) on-going, occurring,happening and / or running measurements forthose measurement objects. If at least one beamlevel measurement is ongoing, at least one cell-level measurement may be suspended, e.g. to avoid duplication. In particular, if at least one beam-level measurement is active, a cell-level measurement may not be necessary. If no beam-level measurement is ongoing, the apparatus, e.g. the UE, may perform or conduct, in particular initiate, trigger and / or start or continue, resume and / or restart the at least one cell-level measurement, e.g. to ensure that the cell remains detectable. In particular, if no beam-level measurement is active, the apparatus, e.g. the UE, may reactivate cell-level measurement, e.g. to ensure cell tracking continuity. To this end, the apparatus, e.g. the UE, may intelligently and / or adaptively manage beam-level (or L1) and cell-level (or L3) measurements, by assessing their association and / or, in particular dynamically, suspending or triggering them, e.g. based on carrier frequency, assigned IDs, and / or measurement object relationships. This approach may ensure efficient resource usage, optimized energy consumption, and / or seamless mobility handling.

[0372] The measurement configuration, in particular the measurement configuration for at least one beam-level measurement (or the measurement configuration for the at least one cell-level measurement) may include an indication, flag or pointer that the at least one beam-level measurement is deactivated initially or by default. As such, the apparatus, e.g. the UE, may need or rely on a (predefined) trigger, condition and / or indication when the at least one beamlevel measurement is to be activated, in particular e.g., cell acquisition procedure, a (specific) network command, and / or timer expiration. This may prevent the UE from performing unnecessary beam-level measurements and / or may save power, e.g. by ensuring beam-level measurements only start when needed. To this end, beam-level measurements may be delayed, e.g. until necessary, which may make the process even more efficient and / or adaptive.

[0373] A cell detection procedure may be performed or conducted for a plurality of candidate cells, e.g. helping the UE to become aware of potential candidate cells and / or to determine which cells are strong enough to be considered, e.g. for cell changes. The plurality of candidate cells may be configured to the apparatus, e.g. the UE, in particular by the network. For example, they may be indicated or included in at least one message, e.g. a Radio Resource Control (RRC) message, which may list these candidate cells, e.g. which may contain a list of cells that the UE should monitor. This may allow the network to be in control over which cell(s) the UE may prioritize. The plurality of candidate cells may be indicated by the capability of the apparatus. For example, the apparatus, e.g. the UE, may autonomously determine whichcandidate cells to include / monitor, e.g. based on its own capabilities. For example, the UE may have an internal algorithm that selects candidate cells, e.g. based on signal strength, frequency bands, and / or mobility history. This may allow for flexibility, e.g. with different hardware capabilities and / or may ensure that legacy and advanced devices can operate efficiently, e.g. without requiring constant network updates.

[0374] The apparatus, e.g. the UE, may be configured as a beam-level measurement trigger threshold, in particular to determine which type of measurement to conduct. The "beam-level measurement trigger threshold" may be regarded as a threshold or (threshold) value, which may determine how / when a measurement, e.g. a beam-level measurement, is to be initiated, triggered and / or started. In addition or alternatively, it may mark a decision point when to transition, change and / or switch from a cell-level measurement to a beam-level measurement. The beam-level measurement trigger threshold may be a (novel) threshold that is specifically constructed and / or designed for / in association with subject-matter described herein. The beamlevel measurement trigger threshold may be included in a measurement configuration as described herein, or separately configured / indicated to the apparatus, e.g. the UE. The beamlevel measurement trigger threshold may be included in i) the measurement configuration for the at least one beam-level measurement of the at least one candidate cell or ii) the measurement configuration for the at least one cell-level measurement of the at least one candidate cell. The beam level measurement trigger threshold can be relative of a serving cell to a candidate or target cell. The beam level measurement trigger threshold can be an existing event like LTM3, LTM4 or A3, A4. In a non-limiting example, Lower Layer Triggered Mobility (LTM) may include or define reporting events, in particular LTM reporting events, like LTM2, LTM3, LTM4, and LTM5 events, which may define specific conditions, events and / or scenarios under which the UE may send one or more measurement reports, e.g. to assist with mobility decisions. For example, a LTM3 Event may occur, e.g. when a signal strength of a beam of a candidate or target cell becomes, e.g. better or stronger, by an amount of offset than a signal strength of a beam of serving cell. For example, when at least one RS of the at least one candidate cell exceeds at least one RS of the serving cell at least by at least one offset value. For example, a LTM4 Event may occur e.g. when a signal strength of a beam of a candidate or target cell becomes better than an, e.g. absolute, threshold etc. In addition thereto or alternatively, the event may be an A3 event, e.g. a measurement event to trigger handover decision. For example, an A3 event may occur when a neighboring cell becomes offset better than the serving cell, e.g. by a defined margin / threshold. The beam level measurement triggerthreshold can have its own offset(s) configuration, e.g. depending on the apparatus, e.g. the UE, hardware configuration. The beam level measurement trigger threshold can be based on any quantity such as RSRP, RSRQ or SINR as described herein.

[0375] The apparatus, e.g. the UE, may, based at least in part on detection of the at least one candidate cell, assess, check, examine and / or verify whether the measurement configuration includes at least one beam-level measurement trigger threshold. In other words, the apparatus, e.g. the UE, may (initially) determined, if the beam-level measurement trigger threshold is configured, exists, is present and / or is available, e.g. in the measurement configuration, e.g. as described herein. This may be viewed as a first action, step and / or process which may be caused by / result from using the beam-level measurement trigger threshold as described herein. This may ensure that beam-level measurements are (only) started when necessary, e.g. avoiding unnecessary power consumption. Based at least in part on this process, the apparatus, e.g. the UE, may determine whether to perform / conduct or whether to at least temporarily suspend at least one cell-level measurement for the at least one candidate cell. For example, the apparatus, e.g. the UE, e.g. upon checking the measurement configuration, may determine that the beam-level measurement trigger threshold is configured or included therein. Based at least in part on this process, the apparatus, e.g. the UE, may perform / conduct the at least one cell-level measurement for the at least one candidate cell. However, the apparatus, e.g. the UE, e.g. upon checking the measurement configuration, may determine that the beamlevel measurement trigger threshold is not configured or included therein. In particular, it may determine that the measurement configuration lacks, is free of, is without and / or fails to include the beam-level measurement trigger threshold. Based on such an assessment, the apparatus, e.g. the UE, may i) suspend at least one cell-level measurement for the at least one candidate cell at least temporarily, or ii) trigger at least one beam-level measurement for the at least one candidate cell. Another, e.g. a second action, step and / or process which may be caused by / result from using the beam-level measurement trigger threshold as described herein, may be to determine whether the beam-level measurement trigger threshold is fulfilled or unfulfilled. In other words, the beam-level measurement trigger threshold may be viewed as a two-step / stage procedure, e.g. to cause respective measurements, in particular by checking i) if the beam-level measurement trigger threshold is configured (or not) and, thereafter, ii) if the beamlevel measurement trigger threshold is fulfilled, met and / or satisfied (or not). This may allow for finer granularity and / or improved accuracy to trigger or suspend respective measurement(s). To determine if the at least one beam-level measurement trigger threshold is fulfilled, theapparatus, e.g. the UE, may compare, a signal strength of the at least one candidate cell with the at least one beam-level measurement trigger threshold. The signal strength of the at least one candidate cell may be based at least in part on performing the at least one cell-level measurement, e.g. it may be measured using at least one cell-level measurement. This may ensure that beam level measurement(s) is / are only activated if the signal is strong enough, e.g. to warrant further analysis. This may also reduce unnecessary beam-level measurements, e.g. when a candidate cell's signal is too weak. If the signal strength exceeds (or at least equals, fulfills, satisfies, or meets) the beam-level measurement trigger threshold, the apparatus, e.g. the UE, may trigger at least one beam-level measurement for the at least one candidate cell. This may allow the apparatus, e.g. the UE, to switch to more detailed beam-level analysis, in particular when the signal conditions justify it. In particular, i) at least one beam-level measurement may be triggered and / or ii) at least one cell-level measurement may be at least temporarily suspended based on the at least one beam-level measurement trigger threshold being fulfilled. As mentioned, this may avoid unnecessary duplication of measurements, which may lead to improved resource management.

[0376] The at least one beam-level measurement trigger threshold may include at least one of the following:

[0377] i) a Reference Signal Received Power (RSRP)-based threshold, which may indicate a power level of reference signals from the cell or beam, e.g. higher RSRP may indicate a stronger or more usable signal;

[0378] ii) a Reference Signal Received Quality (RSRQ)-based threshold, which may indicate a quality of the received reference signal, accounting for interference, e.g. a higher RSRQ may suggest the signal is clear of interference; or

[0379] iii) a Signal-to-lnterference-plus-Noise Ratio (SINR)-based threshold, which may indicate a ratio of the desired signal to interference and noise, e.g. a higher SINR value may mean the signal is strong relative to interference, making it more reliable.

[0380] The at least one beam-level measurement trigger threshold may include at least one threshold which may apply or be applicable for at least one of: - the serving cell, or - the at least one candidate cell. The at least one beam-level measurement trigger threshold may include at least one threshold which applies or is applicable for a specific beam of the at least one candidate cell. This may be, for example, a single beam from a candidate cell that the UE is focusing on. The at least one beam-level measurement trigger threshold may include at least one thresholdwhich applies or is applicable for a group of beams of the at least one candidate cell. This may be, for example, a plurality or a set of beams that are considered collectively, e.g. when deciding whether to trigger beam-level measurements. This may enable a (more) granular control over when and where beam-level measurements are to be activated and / or optimize measurement efficiency, in particular by focusing (only) on relevant beam(s) and / or cell(s).

[0381] According to subject-matter described herein, the apparatus, e.g. the UE, may receive a measurement configuration for at least one candidate cell. The apparatus, e.g. the UE, may assess, check, examine and / or verify whether at least one, in particular predefined, "condition" as described herein may be satisfied, met and / or fulfilled. The at least one condition may be included, configured, defined and / or indicated in the measurement configuration. For example, the at least one condition may be included, configured, defined and / or indicated in i) the measurement configuration for the at least one beam-level measurement or ii) the measurement configuration for at least one cell-level measurement. The condition may be considered fulfilled, satisfied and / or met, e.g. in case a) at least one measurement object indicated in a measurement configuration for at least one cell-level measurement is configured to enable the at least one beam-level measurement or b) at least one at least one beam-level measurement trigger threshold for the at least one candidate cell is fulfilled, e.g. in which case the at least one condition may correspond to at least one beam-level measurement trigger threshold for the at least one candidate cell. At least one beam-level reporting may be triggered based on the at least one beam-level measurement trigger threshold being fulfilled.

[0382] Based at least in part on the condition, in particular based on it being fulfilled (or not), the apparatus, e.g. the UE, may determine whether to perform at least one beam-level measurement or at least one beam-level reporting for the at least one candidate cell. This may be different, in particular based on the at least one condition. In an example, the measurement configuration for at least one beam-level measurement may include or indicate at least one Reference Signal (RS) of the candidate cell to be measured using a first periodicity. The at least one condition may be considered fulfilled in case a measurement configuration for the at least one cell-level measurement included in the measurement configuration indicates i) at least one carrier which covers a frequency of the at least one RS, and ii) that at least one celllevel measurement has a second periodicity which is equal to or greater than the first periodicity. This may ensure that cell-level and beam-level measurements are aligned in terms of frequency and periodicity. This may also, in particular logically, link cell-level measurementsto beam-level measurements and / or may prevent or reduce unnecessary duplication. If the condition is fulfilled, (both) the at least one cell-level measurement for the at least one candidate cell and the at least one beam-level reporting on the (same) at least one candidate cell may be performed / conducted. The decision to perform beam-level reporting (e.g. sending beam measurement results to the network) may be influenced by the results of cell-level measurement. For example, the apparatus, e.g. the UE, may (first) conduct a cell-level measurement, and based on their outcome, it decides whether or not to proceed with beamlevel reporting. This may create an adaptive measurement strategy, e.g. the apparatus, e.g. the UE, may not blindly report beam-level measurements, but may dynamically adjust its reporting, in particular based on broader network conditions. As already mentioned, (both) the cell-level measurement and the beam-level reporting may occur or take place on the same candidate cell, which may allow that measurements and reports are aligned. In another example, the at least one condition may correspond to at least one beam-level measurement trigger threshold for the at least one candidate cell and / or it may be considered to be fulfilled in case at least one beam-level measurement trigger threshold for the at least one candidate cell is fulfilled. Fulfilment of the at least one beam-level measurement trigger threshold may trigger at least one beam-level reporting. The at least one beam-level measurement is triggerable based on at least one of: the at least one beam-level measurement trigger threshold being included or configured in the measurement configuration and / or the at least one beam-level measurement trigger threshold being unfulfilled. The at least one beam-level measurement is triggerable concurrently, e.g. at the same time or in parallel, as cell-level measurements, in particular to verify if the beam-level measurement trigger threshold is met. The apparatus, e.g. the UE may perform / conduct a hierarchical execution of measurements. For example, the apparatus, e.g. the UE, may perform / conduct, in a first step, at least one beam-level measurement to determine whether the at least one beam-level measurement trigger threshold is fulfilled and, in a second step, it may perform / conduct at least one cell-level measurement, in particular concurrently, at the same time or in parallel, to the at least one beam-level measurement to determine whether the at least one beam-level measurement trigger threshold is fulfilled. This may allow real-time decision-making, e.g. by running both measurements in parallel.

[0383] The term "non-transitory," as used herein, is a limitation of the medium itself (i.e., tangible, not a signal) as opposed to a limitation on data storage persistency (e.g., RAM vs. ROM).As used herein, "at least one of the following: " and "at least one of " and similar wording, where the list of two or more elements are joined by "and" or "or", mean at least any one of the elements, or at least any two or more of the elements, or at least all the elements.

[0384] The apparatus may include a processor configured to provide signals to and receive signals and to control the functioning of the apparatus. The processor may be configured to control other elements of apparatus by effecting control signaling via electrical leads connecting processor to the other elements, such as a display or a memory. The processor may, for example, be embodied in a variety of ways including circuitry, at least one processing core, one or more microprocessors with accompanying digital signal processor(s), one or more processor(s) without an accompanying digital signal processor, one or more coprocessors, one or more multi-core processors, one or more controllers, processing circuitry, one or more computers, various other processing elements including integrated circuits (for example, an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), and / or the like), or some combination thereof.

[0394] Fig. 1 shows an example flow chart according to subject-matter described herein. It should be noted that the flow chart of Fig. 1 is merely an example, i.e. the steps depicted and / or discussed should not be considered as limiting. Fig. 1 may be combined with any of the example aspects and / or associated example embodiments mentioned herein. Fig. 1 may be described by the following non-limiting steps:

[0395] Step 0: The apparatus, e.g. the UE may be in a connected mode or state, e.g. a Radio Resource Control (RRC) connected state, e.g. with a cell, e.g. cell 0.

[0396] Step 1: The apparatus, e.g. the UE, may receive a message which may include a measurement configuration for at least one beam-level measurement and a measurement configuration for at least one cell-level measurement. In other words, the at least one beam-level or L1 measurement and at least one cell-level or L3 measurement may be configured to the UE, e.g. by the network.- The measurement configuration for at least one beam-level measurement and the measurement configuration for at least one cell-level measurement may be associated, in particular linked, with one another, e.g. explicitly or implicitly linked.

[0397] - Explicit linking may be through adding the (beam related measurement configuration), e.g. CSi-RS meas config id (e.g. the indication or the ID) in the at least one measurement object included in the measurement configuration for at least one cell-level measurement.

[0398] - Implicit linking may be through looking at the carrier frequency for the CSI-RS meas config, the at least one beam-level measurement and the at least one celllevel measurement and / or the at least one measurement object indicated in the measurement configuration for at least one beam-level measurement and at least one measurement object indicated in the measurement configuration for at least one cell-level measurement.

[0399] - Optionally, it may be conceivable that the measurement configuration, e.g. the measurement for at least one beam-level measurement may include an indication that the at least one beam-level measurement is deactivated initially or by default.

[0400] - In this example let us consider that the L1 measurements are configured for target cell 1. The configuration of beam-level or L1 measurement for cell 1 , can stem from the fact that the cell 1 is a neighbor cell of cell 0 and the apparatus, e.g. the UE, may be moving towards the direction of cell 1. The serving cell might have detected the UE direction, e.g. using measurements or some other beams like statistics of UE mobility in that cell.

[0401] Step 2: The apparatus, e.g. the UE, may perform / conduct cell detection, e.g. indicated by a cell-level or L3 measurement object. This may be for example at least one celllevel measurement, e.g. to detect the at least one candidate cell.

[0402] Step 3: Based at least in part on detection of at least one candidate cell and the at least one message (in particular the measurement configuration for at least one beam-level measurement and the measurement configuration for at least one cell-level measurement included / indicated therein), the apparatus, e.g. the UE, may determine whether to perform or to at least temporarily suspend at least one celllevel measurement for the at least one candidate. The apparatus, e.g. the UE, mayalso determine whether to trigger at least one beam-level measurement, e.g. based on the association between the measurement configuration for at least one beamlevel measurement and the measurement configuration for at least one cell-level measurement. For example, the apparatus, e.g. the UE, may check if the cell 1, is detected, e.g. by having SSBs that are above a certain threshold. The detection threshold may be different than any other threshold as this threshold may be set, considering the "Searcher" hardware at the UE side, if above which a certain peak of a signal is detected from a cell, that cell will be considered detected.

[0403] Step 4: If the candidate cell is detected / identified then the apparatus, e.g. the UE may assess how many measurement objects for the at least one beam-level measurement are associated with at least one measurement object for the at least one cell-level measurement.

[0404] - If there is only a single measurement object for the at least one beam-level measurement (e.g. which may be "referred to as CSI-RS meas config as well beams we want to measure and report";) associated with at least one measurement object for the at least one cell-level measurement, then the apparatus, e.g. the UE, may stop or suspend, at least temporarily, the at least one cell-level or L3 measurement. - If there are more than one, in particular a plurality of measurement objects for the at least one beam-level measurement being associated with at least one measurement object for the at least one cell-level measurement, then the apparatus, e.g. the UE, may determine if at least one (related) beam-level measurement for the at least one candidate cell is occurring for the plurality of measurement objects. If yes, then the apparatus, e.g. the UE, may suspend or stop, at least temporarily, (or may not be required to do) the at least one cell-level measurement for the at least one candidate cell. If no, then the apparatus, e.g. the UE, may keep or continue (or initiate) the at least one cell-level measurement for the at least one candidate cell at least temporarily.

[0405] Step 5: The apparatus, e.g. the UE, may control whether it stopped reporting measurements on this cell or if the signal strength of the cell goes below a threshold. If either holds true, the apparatus, e.g. the UE, can re-start the cell-level or L3 measurement (to possibly detect other beams), in particular after the beam-level or L1measurement(s) fall below a certain threshold. Otherwise, the apparatus, e.g. the UE, may keep on doing beam-level or L1 measurement(s).

[0406] Fig. 2 shows an example flow chart according to subject-matter described herein, which in particular may be combined with the example shown in Fig. 1. Fig. 2 may be combined with any of the example aspects and / or associated example embodiments mentioned herein. It should be noted that the flow chart of Fig. 2 is merely an example, i.e. the steps depicted and / or discussed should not be considered as limiting. In Fig. 2, the steps are similar as in Fig. 1 and / or they may correspondingly apply so that redundant features and / or steps may not necessarily be repeated. The additional steps may be taken from box 200, i.e. the steps, e.g. described with respect to Fig. 1 , may be regarded as optional in this example. The example of Fig. 2, may enable the apparatus, e.g. the UE, to monitor a certain level of signal increase before enabling beam-level measurement(s). The reason for this enhancement may be based on the fact that the beam-level or L1 measurement(s) are (more) complex procedures for the apparatus, e.g. the UE, so it may be beneficial to reduce and / or avoid them, e.g. to keep them at a limited level. Fig. 2 may be described by the following non-limiting steps:

[0407] Step 1 and 2a may be optionally taken from Fig. 1. In particular, the apparatus, e.g. the UE, may receive, e.g. from a serving cell of a network, a measurement configuration for at least one candidate cell.

[0408] Step 3: The apparatus, e.g. the UE, may assess, based at least in part on detection of the at least one candidate cell (s. step 2a), whether the measurement configuration includes at least one beam-level measurement trigger threshold for the at least one candidate cell. In otherwords, the apparatus, e.g. the UE, may check if the threshold is configured, in particular for that cell. As described, the threshold may be a specific and / or preconfigured threshold for beam-level or L1 measurement initiation. Based at least in part on the measurement configuration (and / or its assessment), the apparatus, e.g. the UE, may determine whether to perform or to at least temporarily suspend at least one cell-level measurement for the at least one candidate cell.

[0409] Step 3: (alternative 1: beam-level measurement trigger threshold is not configured). In this case, the solution may work like in Fig. 1 and / or the apparatus, e.g. the UE, may proceed with step 6 (s. arrow "No"). In particular, the apparatus, e.g. the UE, maytrigger at least one beam-level or L1 measurement for the at least one candidate cell based at least in part on assessing that the measurement configuration lacks at least one beam-level measurement trigger threshold for the at least one candidate cell. In addition, or alternatively, the apparatus, e.g. the UE, may suspend at least one cell-level or L3 measurement for the at least one candidate cell at least temporarily.

[0410] Step 3: (alternative 2: beam-level measurement trigger threshold is configured). In this case, the apparatus, e.g. the UE, may proceed with step 4 (s. arrow "Yes"). In particular, the apparatus, e.g. the UE, may perform the at least one cell-level or L3 measurement for the at least one candidate cell, e.g. based at least in part on assessing that the at least one beam-level measurement trigger threshold for the at least one candidate cell is included in the measurement configuration. This may be an initial cell-level measurement or another cell-level measurement, e.g. another one after an initial cell-level measurement.

[0411] Step 5: Based at least in part on performing the at least one cell-level measurement (s. step 4), the apparatus e.g. the UE, may monitor, measure and / or compare a signal strength of the at least one candidate cell with the at least one beam-level measurement trigger threshold, to determine if the at least one beam-level measurement trigger threshold is fulfilled. The at least one beam-level measurement trigger threshold may include at least one of: a Reference Signal Received Power (RSRP)-based threshold, a Reference Signal Received Quality (RSRQ)-based threshold, ora Signal-to-lnterference-plus-Noise Ratio (SINR)- based threshold. Similarly, the threshold may be a threshold to control the target cell signal versus the serving cell signal. The at least one beam-level measurement trigger threshold may include at least one threshold which applies or is applicable for at least one of: the serving cell, or the at least one candidate cell. The at least one beam-level measurement trigger threshold may include at least one threshold which applies or is applicable for i) a specific beam of the at least one candidate cell or ii) for a group of beams of the at least one candidate cell. For example, the threshold may be at a cell-level, for a group of beams (e.g. at least two) or for a specific beam of the candidate cell. It may be noted that there can be more thanone threshold for the target cell and / or the fulfillment of at least one (or all) of the thresholds may initiate the start of the beam-level or L1 measurement(s).

[0412] Step 6: If the at least one beam-level measurement trigger threshold is fulfilled (s. arrow "Yes"), the apparatus, e.g. the UE, may trigger at least one beam-level or L1 measurement for the at least one candidate cell.

[0413] Step 7: If the candidate cell is lost or below a threshold, the process may continue with step 2 (s. arrow "Yes").

[0414] Fig. 3 shows an example flow chart according to subject-matter described herein, which in particular may be combined with the example shown in Fig. 1 and / or Fig. 2. Fig. 3 may be combined with any of the example aspects and / or associated example embodiments mentioned herein. In particular, the example depicted in Fig. 3, may be optionally conducted during step 4 of Fig. 1 and / or step 6 of Fig. 2. It should be noted that the flow chart of Fig. 3 is merely an example, i.e. the steps depicted and / or discussed should not be considered as limiting. Fig. 3 may be described by the following non-limiting steps:

[0415] Step 1 may be optionally taken from Fig. 1 (or Fig 2). In particular, the apparatus, e.g. the UE, may receive, e.g. from a serving cell of a network, a measurement configuration for at least one candidate cell. In this example, the measurement configuration may include a measurement configuration for the at least one beam-level or L1 measurement and a measurement configuration for at least one cell-level or L3 measurement.

[0416] Step 2 / 3: The apparatus, e.g. the UE, may assess, based at least in part on detection of the at least one candidate cell, whether at least one condition associated with the measurement configuration is fulfilled.

[0417] Step 3b: In this example, the at least one condition may be considered to be fulfilled in case at least one measurement object indicated in the measurement configuration for at least one cell-level or L3 measurement is configured to enable the at least one beam-level or L1 measurement. The apparatus, e.g. the UE, may determine if the condition is fulfilled, in particular it may determine if at least one measurement object indicated in the measurement configuration for at least one cell-level or L3measurement is configured to enable the at least one beam-level or L1 measurement. For example, the measurement configuration for the at least one beam-level measurement included in the measurement configuration may indicate at least one Reference Signal (RS), e.g. a specific SSB index etc., of the at least one candidate cell to be measured using / with a first periodicity. The apparatus, e.g. the UE, in particular at the same time or concurrently therewith, may determine or check, whether the measurement configuration for the at least one cell-level measurement included in the measurement configuration indicates i) at least one carrier which covers a frequency of the at least one RS, e.g. the SSB index, and whether ii) at least one cell-level measurement has a second periodicity which is equal to or greater than the first periodicity.

[0418] Step 4b: Based on this determination of Step 3b, e.g. based at least in part on fulfillment of the at least one condition (s. arrow "Yes"), the apparatus, e.g. the UE, may perform / conduct at least one cell-level or L3 measurement for the at least one candidate cell and perform / conduct at least one beam-level or L1 reporting on the at least one candidate cell. The at least one beam-level or L1 reporting on the at least one candidate cell may be performed / conducted based at least in part on the at least one cell-level or L3 measurement for the at least one candidate cell. As such, the apparatus, e.g. the UE, which may be required to do the beam-level or L1 measurement, may keep doing cell-level or L3 measurement(s). In another example, all the other configurations of the beam-level or L1 measurement(s) shall be fulfilled by the cell-level or L3 measurement outcome; e.g. the apparatus, e.g. the UE, may perform cell-level or L3 measurement(s), but may perform beam-level or L1 reporting.

[0419] Step 4a: Based on this determination of Step 3b, e.g. based at least in part on the at least one condition being unfulfilled (s. arrow "No"), the apparatus, e.g. the UE, may suspend at least one cell-level measurement, at least temporarily and may conduct / perform at least one beam-level or L1 measurement.

[0420] Step 5 may be optionally taken from Fig. 1 (or Fig 2).Fig. 4 shows an example flow chart according to subject-matter described herein, which in particular may be combined with the example shown in Fig. 1, Fig. 2 and / or Fig. 3. Fig. 4 may be combined with any of the example aspects and / or associated example embodiments mentioned herein. In particular, the example depicted in Fig. 4, may be optionally conducted / triggered during step 2 of Fig. 2. Thus, one or more steps, in particular of Fig. 2, may be taken and / or correspondingly / similarly applied to the example of Fig. 4. These steps may not be repeated. It should be noted that the flow chart of Fig. 4 is merely an example, i.e. the steps depicted and / or discussed should not be considered as limiting. Fig. 4 may be described by the following non-limiting steps:

[0421] Step 1 may be optionally taken from Fig. 1, Fig. 2 or Fig 3. In particular, the apparatus, e.g. the UE, may receive, e.g. from a serving cell of a network, a measurement configuration for at least one candidate cell. In this example, the measurement configuration may include a measurement configuration for the at least one beam-level or L1 measurement and a measurement configuration for at least one cell-level or L3 measurement.

[0422] Step 2: The apparatus, e.g. the UE, may assess, based at least in part on detection of the at least one candidate cell, whether at least one condition associated with the measurement configuration is fulfilled. In this example, the at least one condition may correspond to at least one at least one beam-level measurement trigger threshold for the at least one candidate cell (cf. Fig. 2). The at least one condition may be considered to be fulfilled in case at least one at least one beam-level measurement trigger threshold for the at least one candidate cell is fulfilled (s. Step 5).

[0423] Step 6: At least one beam-level reporting may be triggered based on the at least one beamlevel measurement trigger threshold being fulfilled (s. step 5, arrow "Yes") and / or the threshold not being configured (s. step 3, arrow "No").

[0424] Step 4: In an example, the apparatus, e.g. the UE, may perform / conduct at least one beamlevel or L1 measurement and / or at least one cell-level or L3 measurement to determine whether the beam-level measurement trigger threshold is fulfilled. Performing of the at least one cell-level measurement may be concurrently to the atleast one beam-level measurement, e.g. to determine whether the at least one beam-level measurement trigger threshold is fulfilled (s. Step 5).

[0425] Step 3 / 5: In the case of step 3, e.g. the threshold being configured (s. arrow "Yes") and / or the threshold not being fulfilled or being unfulfilled (s. Step 5, arrow "No"), at least one beam-level measurement may be triggerable / triggered (and / or at least one cell-level measurement). In other words, the at least one beam-level measurement may be triggerable based at least in part on at least one of: i) the at least one beam-level measurement trigger threshold being included in the measurement configuration, or ii) the at least one beam-level measurement trigger threshold being unfulfilled.

[0426] In the example of Fig. 4, the apparatus, e.g. the UE, may detect the cell with cell-level or L3 measurement(s), and / or may start measuring the cell with beam-level L1 measurement(s). Measuring through beam-level or L1 measurement(s) may indicate that the apparatus, e.g. the UE, may use different receive beamforming, then it may use for cell-level or L3 measurement(s). The apparatus, e.g. the UE, may obtain samples and apply filtering during steps 3-4-5 is being processed. Once the condition is step 5 is fulfilled, the apparatus, e.g. the UE, may start beam-level or L1 reporting. It may be up to the apparatus, e.g. the UE, to (also) perform / conduct beam-level or L1 measurement(s) without any changes (already) in step 4.
