[0408] DETAILED DESCRIPTION

[0409] 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 afurther embodiment. It is intended that the description includes such modifications and variations.

[0410] 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.

[0411] A "mobility procedure" may be regarded as or may refer to a process of transitioning, switching and / or changing 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 / change 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 / changes, 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 measurement(s) 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.

[0412] The 3rdGeneration Partnership Project (3GPP) introduced L1 / L2 triggered mobility (LTM), where the network may configure the apparatus, e.g. the UE, with, e.g. up to 8 LTM, candidate cells, where each, candidate cell configuration may include for example a Layer 1 (L1) measurement (and reporting) configuration, a candidate TCI state configuration etc. A cell switch command or cell change command may include a target TCI state, which may be one of the configured candidate TCI state(s) for the target cell. A "Transmission Configuration Indication (TCI) state" may represent a configuration of reference signals (RS) and / or beams for, in particular optimized, communication with a specific candidate cell. For example, the TCI state may define a set of transmission parameters (such as beam direction and / or spatial filtering) that the apparatus, e.g. the UE, may assume for, in particular specific, reference signals (RS), e.g. in a serving cell. A cell switch or cell change may, for example, be RandomAccess Channel (RACH)-based, for example, the apparatus, e.g. the UE, may perform a RACH-procedure, in particular during the cell change (e.g., after reception of the cell change command). Alternatively, the cell change may be RACH-less, for example, if a Timing Advance (TA) is available for the target cell, e.g. either through UE-based TA estimation or provided in the cell change command. Optionally, the network or network device may indicate to the apparatus, e.g. the UE, to perform, in particular fine, Downlink (DL) timing synchronization, e.g. for one or more of the configured candidate TCI state(s), in particular before transmitting the cell change command. This may be done through, e.g. LTM, candidate TCI state activation Medium Access Control (MAC)- Control Element (CE), where with one MAC-CE the network may activate one or more TCI state(s), in particular for a single candidate cell. With a separate MAC-CE, the network may activate one or more TCI state(s), e.g. for another candidate cell. Optionally, the network may also configure, in particular early, Uplink (UL) synchronization, for example either through Physical Downlink Control Channel (PDCCH) ordered RACH transmission, in particular for one or more candidate cell(s), e.g. performed before the cell change, or through configuring the apparatus, e.g. the UE, to perform UE-based TA estimation.

[0413] "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.

[0414] 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. For example, based on reported UE measurements (e.g., Layer 1 (L1) and / or Layer 3 (L3) measurement(s)), the network may send a cell switch / change command, e.g. for at least one of the configured candidate cell(s) (or target cell(s)). Exemplary measurement requirements, in particular for LTM candidate cell Layer 1 (L1) measurements, may be taken from section 9.14 (e.g. intra-frequency measurement(s)) and / or section 9.15 (e.g. inter-frequency measurement(s)) of TS 38.133. For example,sections / tables 9.14.5.1-3 are exemplarily reproduced below, but should not be considered limiting:

[0420] NOTE 1: TSSB_NBC is the periodicity of the neighbor cell SSB-lndex configured for intra-frequency L1-RSRP measurement. TDRX is the DRX cycle length. TReport is configured periodicity for reporting.

[0421] NOTE 2: The requirements apply when the max RTD between the serving cell and any candidate cell on which UE is required to perform L1-RSRP measurement on the same frequency layer is not larger than CP length of the cell on the frequency layer.

[0422] NOTE: When the number of neighbor cells to be measured on intra-frequency and inter-frequency without gap is more than 1 and TCI state(s) of at least one of these neighbor cells is in the active TCI state list, the requirements apply only to the cell(s) that have TCI state(s) is in the active TCI state list.

[0423]

[0424] Where:

[0425] - PL1_sharing is defined as

[0426] - When number of neighboring cells configured with SSB based L1-RSRP measurement is 1- PL1_sharing = 2, if any symbol of the SSBs from serving cell and neighbor cell are overlapping or adjacent (in time domain)

[0427] - PL1_sharing = 1, otherwise

[0428] - When number of neighboring cells configured with SSB based L1-RSRP measurement is more than 1

[0429] - When none of TCI state(s) of the intra-frequency neighbor cells or inter-frequency neighbor cells without gap are not in the active TCI state list

[0430] - PL1_sharing = 3*NNeighbor_Cell, where NNeighbor_Cell is the number of neighbor cells (to measure on intra-frequency and inter-frequency without gap) whose TCI state(s) are not in the active TCI state list

[0431] - Otherwise

[0432] PL1_sharing = 3*NNeighbor_Cell_in_list, where NNeighbor_Cell_in_list is the number of neigbour cells (including intra-frequency neighbor cells and interfrequency without gap neighbor cells) whose TCI state(s) are in the active TCI state list. No requirements are defined for any other cell(s) whose TCI state(s) is not in the active TCI state list.

[0433] An enhancement to a mobility procedure and / or a cell change procedure, e.g. to LTM, may be by enabling the apparatus, e.g. the UE, to initiate, trigger and / or induce cell change procedure, e.g. through at least one, in particular network configured, condition becoming fulfilled, met and / or satisfied, which may be referred to as conditional cell change procedure, in particular conditional Lower Layer (or L1 / L2) Triggered Mobility (LTM) cell change procedure or short CLTM. For example, the network may configure condition for one or more of the candidate cell(s) in the LTM candidate cell configuration. The apparatus, e.g. the UE, may evaluate the configured condition(s) and initiate and / or trigger a cell change, e.g. once the CLTM condition becomes fulfilled, satisfied and / or met for a candidate cell. For example, the network can optionally indicate activation of one or more TCI state(s), e.g. for one or more candidate cell(s), in particular through TCI state activation MAC-CE. However, the network may also optionallyconfigure, e.g. early, UL sync through PDCCH order, in particular followed by RACH preamble transmission, e.g. to the candidate cell and / or by network sharing the TA estimated by the target cell to the apparatus, e.g. the UE, through in particular a MAC-CE with the TA value and / or a timer associated to the TA. When the timer is running, the apparatus, e.g. the UE, may be able to perform, e.g. a RACH-less conditional cell switch, in particular based on the shared TA. The network may also configure the UE-based TA estimation for one or more candidate cell(s).

[0434] During the conditional cell change procedure, the apparatus, e.g. the UE, may evaluate all configured condition(s), which may be referred to as "CLTM condition(s)" (these may correspond to the legacy conditions or legacy CLTM conditions), e.g. starting from the, e.g. LTM, configuration. For example, an LTM3-like and / or an LTM5-like condition may be configured for a candidate cell, in particular when the condition is, e.g. L1-based, wherein in particular:

[0435] LTM3 Event: This 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, wherein at least one measured RS of the at least one candidate cell exceeds at least one measured RS of the serving cell at least by at least one offset value;

[0436] LTM5: This event may occur e.g. when a signal strength of a beam of a serving cell becomes worse than the, e.g. absolute, threshold, e.g. threshold 1, and a signal strength of a beam of a candidate or target cell becomes better than another, e.g. absolute, threshold, e.g. threshold 2.

[0437] When the condition is, for example L3-based, CondEventA3- and / or CondEventA5-condition(s) may be used as baseline for the conditional cell change (e.g. LTM) execution. The exemplary and non-limiting definition of these conditions for a Conditional Handover (CHO) are outlined below. The definition for CLTM may be expected to be similar or slightly adjusted:

[0438] CondEventA3: Conditional reconfiguration candidate may become an amount of offset better than a Primary Cell (PCell) and / or a Primary Secondary Cell (PSCell).CondEventA5: PCell / PSCell may become worse than an, e.g. absolute, threshold, e.g. threshold 1 and a conditional reconfiguration candidate may become better than another, e.g. absolute, threshold, e.g. threshold 2.

[0439] At the time of receiving an, e.g. LTM, candidate cell configuration, in particular with one or more conditions, e.g. for CLTM, the apparatus, e.g. the UE, may start evaluating all the configured conditions. For condition evaluation, CLTM may be expected to follow certain measurement requirements. This may mean that, for example, at early TCI state activation for one (or more) candidate cell(s), measurement requirements for e.g. L1 measurements on other candidate cells may stop applying, in particular, the apparatus, e.g. the UE, may be allowed to stop L1 measurement(s) on other candidate cell(s). This may mean, for example, that if a L1 -based CLTM condition is configured for one or more of the candidate cell(s), e.g. without active TCI states, it may be unclear whether the apparatus, e.g. the UE, will / should continue to evaluate the condition, e.g. using L1 measurement(s) on those candidate cell(s) and / or to execute a cell change if the condition becomes fulfilled. This may create uncertainty in the whole procedure.

[0440] It may be beneficial, among other things, to define, address and / or improve UE measurement behavior / requirement(s) and / or condition evaluation behavior of the apparatus, e.g. the UE, for example related to existing signaling (e.g. TCI state activation, PDCCH order etc.) and / or the existing measurement requirement(s), e.g. where both L1 -based and L3-based measurement(s) and / or condition(s) shall be considered. The subject-matter described herein aims to address at least some of these challenges.

[0441] A "candidate cell configuration" may include information about one or more candidate cell(s) and / or may refer to the set of parameters and / or rules that define, e.g. how the apparatus, e.g. the UE, may conduct or perform one or more measurement(s). The candidate cell configuration may also be referred to as "mobility configuration" or may include or correspond to a "measurement configuration". In particular, the candidate cell configuration may be provided by the network and / or may include, specify and / or indicate at least one measurement. It may also be said that the apparatus, e.g. the UE, is configured with one or more measurements for at least one or two candidate cells, e.g. fora cell change. For example, it may indicate a type, category and / or kind of measurement, in particular to be conducted. The candidate cell configuration may also indicate what the apparatus, e.g. the UE, should measure, such as, e.g. at least one signal, e.g. Channel State Information (CSI) Reference Signal (RS)-based, aSynchronization Signal Block (SSB), a SSB-based Synchronization Signal or the like. In other words, it may define 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 etc.

[0442] According to subject-matter described herein, the candidate cell configuration may include or indicate "at least one measurement". The at least one measurement may be at least one of: a beam-based measurement, a Reference Signal, RS, -based measurement, a Synchronization Signal Block, SSB, -based measurement, a Channel State Information, CSI, -based measurement. A "beam" or "at least one beam" or a respective measurement thereof may be used interchangeably herein with a RS and 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. 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 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 (SINR), e.g. a ratio of the desired signal power to interference and / or noise power. Other properties and / or metrics are conceivable. A "Synchronization Signal Block", "synchronization signal / PBCH block" or "SSB" may be regarded as a component or signaling or, it may be at least part of a signaling, that may be used in wireless communication, such as for example 5G or NR, to facilitate a synchronization or synchronization process between the apparatus, e.g. the UE, and a base station, e.g. of a network. The SSB may provide signals, channels and / or information that enable the device to, in particular initially, connect and / or stay synchronized with the base station, allowing it, for example, to communicate effectively over the network. "Channel State Information" or CSI may refer to the information about a state, condition and / or status of a channel, in particular that an apparatus, e.g. a UE, may report, e.g. to the network or network device (e.g. gNB in 5G). CSI may provide insights into the quality of a channel, e.g.enabling the network to optimize data transmission (e.g., selecting the best modulation scheme, power control, beamforming, and / or MIMO techniques etc.).

[0443] In addition or alternatively, the at least one measurement may be at least one of: a Layer 1, L1, measurement, or a Layer 3, L3, measurement. A Layer 1 (L1) measurement may may include physical-layer measurement(s), e.g. 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 cell changes, handovers, beam management, and / or connection re-establishments. 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. Intra-frequency L1 measurements may refer to measurements performed on reference signals, e.g. transmitted on a same carrier frequency 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. Reference Signals used for L1 measurements may include Synchronization Signal Blocks (SSBs), Channel State Information Reference Signals (CSI-RS) etc. A Layer 3 (L3) measurement 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.

[0444] The candidate cell configuration may be for a conditional cell change procedure. In particular the candidate cell configuration may include at least one condition, in particular for at least one of the configured candidate cells, e.g. in particular a CLTM condition as mentioned above, for the conditional cell change procedure. The candidate cell configuration may be a Lower Layer Triggered Mobility, LTM, configuration, in particular for a conditional cell change procedure, e.g. for a conditional LTM cell change procedure. The conditional cell change procedure asdescribed herein may be a following or subsequent cell change procedure (e.g., the apparatus, e.g. the UE, may not release the candidate cell configuration, nor the condition for conditional cell change upon execution. Rather, the apparatus, e.g. the UE, may maintain the candidate cell configuration and / or the condition for conditional cell change.

[0445] A "candidate cell" (or "target cell") may be referred to as a neighboring cell that the apparatus, e.g. the UE, evaluates as a potential replacement for the current serving cell, in particular during a mobility event. If or when particular conditions are met / satisfied, the UE may initiate a transition / change process to a candidate cell selected as the target cell. The "serving cell" may the active cell currently providing network connectivity to the UE. The UE may, in particular continuously, measure the quality of the serving cell and compare it with potential candidate cell(s) to determine if a mobility event is required. LTM candidate cell(s) may be neighboring cell(s) or a UE’s current serving cells.

[0446] The candidate cell configuration may include or indicate at least one measurement for "at least one candidate cell" or for "at least two candidate cells", e.g. a plurality, a group and / or a set of candidate cells. On other words, the subject-matter described herein may be applicable to the case of i) having at least (e.g. only one and / or a single) candidate cell and / or ii) having at least two candidate cells. In the example i), there may be at least one (e.g. only one and / or a single) candidate cell, which may be configured, e.g. with a plurality or multiple measurements. A trigger, e.g. the trigger according to subject-matter as further described herein, may impact, influence and / or affect for example some measurement(s) of this at least one candidate cell. In a particular and non-limiting example, a candidate cell 1 may be configured with, e.g. L1 measurement(s) and e.g. L3 measurement(s). The trigger may indicate to the apparatus, e.g. the UE, to stop the e.g. L1 measurement, but to continue the e.g. L3 measurement. The apparatus, e.g. the UE, may then stop, in particular if there is no e.g. L1 condition, otherwise the apparatus, e.g. the UE, may continue e.g. the L1 measurement.

[0447] 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, for example related to a measurement requirement / behavior, and a second indication or second part of the indication indicating a second information, for example a condition evaluation behavior etc.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 / part and / or the second information / part or the indication as a whole, may indicate that at least one of: a measurement requirement, or a measurement behavior of the apparatus is to be adjusted, changed, modified, adapted, controlled, altered, amended, revised, corrected and / or edited (these terms may be used interchangeably herein). The indication may be an explicit indication, e.g. (directly) included, embedded or encoded in a message, e.g. directly readable by the apparatus, or it may be conceivable that the indication is indicated or included in the candidate cell configuration. The indication may be a flag, or pointer which is included or encoded in the message or the candidate cell 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 candidate cell configuration or the message. The indication may also be an implicit indication, e.g. derivable from the message or the candidate cell configuration itself, e.g. the UE, may conclude to the indication based at least in part on the message or the candidate 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.

[0448] A measurement "requirement" may refer to a need, obligation, necessity and / or duty for the apparatus, e.g. the UE, to perform / conduct at least one measurement and / or an associated reporting. In other words, a "requirement" may cause, initiate, trigger, infer, demand, request and / or force a (corresponding) behavior, e.g. a (corresponding) measurement of the apparatus, e.g. the UE. A measurement "behavior" may be related to a characteristic, type and / or condition of the measurement and / or how it is taken, e.g. related to a measurement frequency, measurement type, signal-type, etc. as mentioned above. The at least one requirement and / or the measurement behavior may follow from and / or be specified, defined, or predetermined in standard document(s). For example, the measurement requirement, or the measurement behavior of the apparatus, in particular the one, indicated in the at least one indication, may differ, deviate, diverge and / or depart from at least one of: a "standard measurement requirement", ora "standard measurement behavior" (e.g. respectively) of the apparatus. The "standard measurement requirement" and / or the "standard measurement behavior" may be a legacy requirement / behavior and / or a baseline reference, -rule and / or -regulation. In other words, the indication can override the standard measurement rules, e.g. defined by standardspecifications. This may allow more flexibility, e.g. to fine-tune performance beyond rigid standards and / or may allow for network-driven optimizations, e.g. in special scenarios. For example at least one of: the standard measurement requirement, or the standard measurement behavior of the apparatus may be defined, indicated and / or specified in a standard specification. In an example, it may be the case that a standard measurement requirement, or a standard measurement behavior of the apparatus stipulates to conduct at least one measurement of a certain type, while the indication may indicate to refrain from conducting the at least one measurement, or may at least influence and / or change this. It should be noted that other examples may be conceivable. Further examples how the indication may affect and / or influence the measurement requirement / behavior are given below and / or outlined herein. However, in that sense, it may be also said that the requirement may be deactivated, turned-off, paused, halted, disabled, suspended and / or stopped. Likewise, the requirement may be activated, turned-on, continued, enabled, resumed and / or initiated. As such, the requirement may be i) controllable, ii) switchable, iii) configurable iv) changeable, v) adjustable and / or vi) selectable. The aforementioned terms may be used interchangeably herein. This may be done at least once, or multiple times.

[0449] According to subject-matter described herein, the apparatus may adjust, change, modify, adapt, control, alter, amend, revise, correct and / or edit (these terms may be used interchangeably herein) the at least one measurement in association with the conditional cell change procedure, based at least in part on the at least one indication. This may include at least one of: i) enabling or disabling; ii) refraining from conducting; iii) stopping, pausing, skipping, ceasing, halting, deactivating and / or ending, in particular at least temporarily; iv) conducting; v) initiating, starting, triggering, causing, activating and / or inducing; and / or vi) proceeding, continuing, resuming, maintaining and / or keeping, the at least one measurement, in particular in association with the conditional cell change procedure. It should be noted that the terms used for each i)-vi) may be used interchangeably herein. The subject-matter described herein may therefore include conducting the at least one measurement in association with the conditional cell change procedure based at least in part on the at least one indication, or refraining from conducting or stopping the at least one measurement in association with the conditional cell change procedure based at least in part on the at least one indication. Reducing, e.g. unnecessary measurement(s), may extend UE battery life and / or avoiding redundant and / or low-value measurement(s) may decrease processing power usage. Reducing e.g. unnecessary measurement(s) may also lead to the apparatus, e.g. the UE, beingable to perform the remaining measurement(s) faster, leading e.g. to faster reporting and / or mobility decisions. By selectively adjusting measurement(s) and / or their requirements / behavior, the network may minimize unnecessary measurement reports, which may improve signaling overhead. The subject-matter described herein may reduce measurement delays and / or enable the apparatus, e.g. the UE, to dynamically adapt, e.g. to specific conditions, e.g. in real-time.

[0450] The at least one indication may apply or be applicable for at least one candidate cell of the at least (one or) two candidate cells. In other words, the indication that that at least one of: a measurement requirement, or a measurement behavior of the apparatus is to be adjusted may apply or be applicable, e.g. selectively, to (only) one candidate cells or more candidate cells or, it may apply or be applicable, e.g. collectively, to all candidate cells. This may provide a more granular control over the measurement process and / or allow to target specific candidate cells for adjustment(s), e.g. instead of applying the indication or its content uniformly.

[0451] The at least one indication may further indicate that a condition evaluation behavior of the apparatus of at least one condition included or indicated in the candidate cell configuration is to be adjusted or is to remain unchanged. In the latter case, for example, instead of modifying condition evaluation behavior, the indication can instruct the apparatus to maintain its current evaluation settings. The same may also apply for a measurement behavior / requirement. Influencing the condition evaluation behavior may be regarded as a, in particular network-sided and / or network-initiated, control of condition evaluation of the apparatus, e.g. the UE. This may enable adaptive and / or dynamic evaluation logic based on real-time network conditions. "Evaluating a condition" or "condition evaluation" may mean that at the event of condition for cell change becoming met, fulfilled and / or satisfied, the apparatus, e.g. the UE, may execute a cell change to the candidate cell for which the condition is met. Not evaluating the condition may mean that the apparatus, e.g. the UE, may not execute a cell change, e.g. based on this condition. Condition evaluation may apply as long as the condition is configured, but there may be also a trigger, e.g. to activate / deactivate condition evaluation. This may be achieved using the at least one indication as mentioned herein. However, the triggering event may or may not trigger start / stop of condition evaluation.

[0452] The at least one indication may be regarded as a network signal, e.g. a network-initiated, trigger or trigger signal, in particular to affect the measurement requirement and / or -behavior of theapparatus, e.g. the UE. The at least one indication may also be referred to as trigger, in particular according to subject-matter described herein. The at least one indication may be included and / or indicated in different types of commands, signaling and / or messages, whereas it may also be conceivable to send the at least one indication separately, independently and / or individually. For example, the at least one indication may be included in, embedded in, or it may correspond to a Transmission Configuration Indicator, TCI, state activation command for at least one of the at least two candidate cells. For example, the at least one indication may be included in, embedded in, or it may correspond to a Timing Advance, TA, acquisition command for at least one of the at least two candidate cells. The TA acquisition command may be at least one of: at least one Physical Downlink Control Channel, PDCCH order; (e.g. at least one, a first, or another) Medium Access Control, MAC, Control Element, CE message; at least one Downlink Control Information, DCI, message; or at least one Abstract Syntax Notation One, ASN.1, message. For example, the at least one indication may be included in, embedded in, or it may correspond to a Medium Access Control, MAC, Control Element, CE, in particular with Timing Advance, TA, information for at least one of the at least two candidate cells. The at least one indication may also activate at least one of: a Reference Signal, RS, RS transmission, or measurement of a RS for at least one of the at least one or two candidate cells. For example, a MAC-CE may activate a semi-persistent CSI-RS for a candidate cell etc. For example, the at least one indication may be included in, embedded in, or it may correspond to a cell change command.

[0453] Instead of using the at least one indication, at least one "measurement based condition" may be used. This may improve and / or reduce signaling overhead. According to subject-matter described herein, the apparatus, e.g. the UE, may determine fulfillment of at least one measurement-based condition for at least one candidate cell of the at least two candidate cells. It should be noted that, e.g. herein, instead of saying "the apparatus, e.g. the UE, may determine fulfillment of at least one measurement-based condition for at least one candidate cell of the at least two candidate cells", it may be said "the apparatus, e.g. the UE, may determine whether the at least one measurement-based condition is fulfilled for at least one candidate cell of the at least two candidate cells", i.e. these passages may be used interchangeably herein. The at least one measurement-based condition may be embedded in, included in, and / or indicated in the candidate cell configuration. The at least one measurementbased condition may differ from a, e.g. conventional / legacy, condition, in particular from a conditional cell change execution condition, e.g. CLTM as mentioned above. The at least onemeasurement-based condition may be provided, e.g. in addition to, extra, further to, complementary to, supplementary to and / or on top of at least one conditional cell change execution condition, e.g. CLTM as mentioned above. The at least one measurement-based condition may be for initiation, triggering and / or inducing (and / or) execution of the conditional cell change procedure, in particular for at least one candidate cell of the at least two candidate cells.

[0454] According to subject-matter described herein, fulfillment of the at least one measurementbased condition may indicate or specify that at least one of: a measurement requirement, or a measurement behavior of the apparatus is to be adjusted, changed, modified, adapted, controlled, altered, amended, revised, corrected and / or edited (these terms may be used interchangeably herein). As it was the case for the at least one indication, the at least one measurement-based condition may be regarded as a trigger or trigger event, in particular to affect the measurement requirement and / or -behavior of the apparatus, e.g. the UE. The at least one measurement based condition may also be referred to as trigger, in particular according to subject-matter described herein. According to subject-matter described herein, the apparatus may adjust, change, modify, adapt, control, alter, amend, revise, correct and / or edit (these terms may be used interchangeably herein) the at least one measurement in association with the conditional cell change procedure, based at least in part on fulfillment of the at least one measurement-based condition. In other words, instead of using the at least one indication, the at least one measurement-based condition may be used. As such, the preceding features, steps and / or characteristics outlined for / in association with the at least one indication may apply in the same way or at least similarly for the at least one measurement-based condition, and are not repeated here.

[0455] The at least one measurement-based condition may include at least one of: a Layer 1 , L1 , measurement-based condition, ora Layer 3, L3, measurement-based condition. For example at least one or each candidate cell may be configured with i) no measurement-based condition, ii) a L1 measurement-based condition, iii) a L3 measurement-based condition, or iv) both of a L1 measurement-based condition and a L3 measurement-based condition. Determination on whether to perform the one or more measurements, e.g. L1 or L3 measurements, in particular after the trigger / triggering event, may be related to any of these options, as further described below.According to subject-matter described herein, the apparatus, e.g. the UE, may determine (e.g. whether) to conduct, or to refrain from conducting the at least one measurement in association with the conditional cell change procedure based at least in part on whether: i) at least one measurement-based condition is being configured for at least one of the at least two candidate cells, and ii) the apparatus is being configured to evaluate the at least one measurement-based condition. In other words, the determination of whether a measurement is to be conducted on a candidate cell, e.g. another candidate cell than the one the triggering event considers, in particular after the triggering event, may be based on i) whether a (L1 measurement-based, and / or L3 measurement-based) condition for cell change is configured, and ii) whether the apparatus, e.g. the UE, is configured to evaluate one or more of the configured cell change conditions, in particular after the triggering event.

[0456] "determine (e.g. whether) to conduct, or to refrain from conducting" may mean, that the apparatus, e.g. the UE, may make a decision, choose and / or select whether a measurement should be conducted or not. Detailed examples for the determination of whether to perform a measurement (or not) are exemplarily outlined below. It should be noted that each example or option is marked with a number, e.g. Options 1a-6b. This may become relevant for the example specification impact as outlined below, which the subject-matter described herein may have thereon, in particular in order to connect, associate and / or combine the feature(s) / subject-matter described herein with the impact the same may have on the standard specification.

[0457] In a first example, a conditional cell change condition on the candidate cell to be measured may be considered. In particular, the at least one measurement-based condition may be configured for a candidate cell of the at least two candidate cells that is to be measured.

[0458] Option 1

[0459] According to one example, the at least one measurement may be conducted, in particular based at least in part on a candidate cell to be measured being configured with the at least one measurement-based condition, in particular for a same measurement type as the at least one measurement on the candidate cell to be measured. This may be regarded as Option 1a.

[0460] The at least one measurement may be conducted, e.g. based at least in part on the apparatus being configured to evaluate the at least one measurement-based condition for a samemeasurement type as the at least one measurement on the candidate cell to be measured. This may be regarded as Option 1b.

[0484] In other words, the apparatus, e.g. the UE, may perform, e.g. a L1 / 3 measurement if configured with L1 condition, e.g. for any cell.

[0485] It may be noted, that "conducting" or "performing" the measurement in any of the above Options 1a-6b and / or as described herein, may mean that the apparatus, e.g. the UE, is required to conduct / perform the measurement and / or that the measurement is taken into account, e.g. in the measurement delay requirement. For example, it the apparatus, e.g. the UE, may not be required to perform the measurement (or it may be allowed to stop, or not conduct / perform the measurement), the apparatus, e.g. the UE, may or may not perform the measurement, but this measurement may (then) not be taken into account, e.g. in the measurement delay requirement.

[0486] In the following, non-limiting examples for alternatives and / or additional embodiments or example options are outlined:

[0487] - An alternative way to capture Options 1a-6b may be to say that the apparatus, e.g. the UE, is allowed to stopping, pausing, skipping, ceasing, halting, deactivating and / or ending, in particular at least temporarily; or to not conduct / perform or to refrain from conducting / performing a measurement, e.g. if the condition in any one of Options 1a- 6b (and their sub-options) is not met, satisfied and / or fulfilled;

[0488] Being allowed to stop (or not perform) a measurement based on any of the Options 1a- 6b on a candidate cell may consequently and / or implicitly lead to the apparatus, e.g.the UE, not evaluating a related cell change condition, e.g. for this candidate cell, in particular if configured with one;

[0489] - More than one of Options 1a-6b may be applied for each candidate cell / measurement; - One or more of the different Options 1a-6b may apply to different measurement types (e.g. Option 1a may apply for L1 measurement and option 2a may apply for L3 measurement etc.);

[0490] - One or more of the different Options 1a-6b may also apply to the cell that the triggering event considers and / or to other cells;

[0491] Different triggering events may lead to one or more of the different Option 1a-6b. For all Options 1a-6b above "the same / specific measurement type" may in addition to L1 / L3 separation also or instead of this mean, e.g. separation based on RS type, e.g. SSB-based, or CSI-RS-based. The separation may also be for any other than existing measurement classification in any future technology (e.g. L1 / L2 / L3, or for any new RS type);

[0492] - The measurement / cell change condition configuration for a cell may also be a configuration for a beam or RS, where Options 1a-6b may apply to the measurement, e.g. depending on a conditional cell change condition, in particular for the same / different / specific beam / RS etc.

[0493] It should be noted that any of the above options may be combined with the trigger or trigger event as described herein, in particular with i) the at least one indication which may indicate that at least one of: a measurement requirement, or a measurement behavior of the apparatus is to be adjusted (e.g. the at least one trigger event / trigger may be a network-initialized trigger event / trigger) and / or ii) (fulfillment of) the at least one measurement-based condition which may indicate that at least one of: a measurement requirement, or a measurement behavior of the apparatus is to be adjusted (e.g. the at least one trigger event may be based on a trigger condition / trigger included or indicated in the candidate cell configuration). The options i) and ii) may be referred to herein as trigger and / or trigger event. A such, determining whether to conduct or to refrain from conducting the at least one measurement in association with the cell change procedure may be triggered, initiated and / or induced based at least in part on, and / or after at least one trigger event or the at least one trigger, e.g. at least one of: i)-ii).

[0494] The determined and / or adjusted measurement requirement / behavior may be determined to continue on a candidate cell, e.g. based on any of the following Options l-VIII below, inparticular the adjusted measurement requirement / behavior may continue until (e.g. referring to at least one time period, slot and / or window of how long it may continue):

[0495] I. the apparatus, e.g. the UE, executes the cell change, e.g. based on a

[0496] cell change condition becoming fulfilled, e.g. for any of the candidate cells (e.g. L1 or L3 based);

[0497] II. the apparatus, e.g. the UE, may receive a cell change command, e.g. for any of the candidate cells;

[0498] III. the apparatus, e.g. the UE, may receive a TCI state activation command, e.g. to deactivate all TCI states for the candidate cell;

[0499] IV. expiry / after of a predefined and / or network-configured time duration (e.g. a timer);

[0500] V. RRC reconfiguration;

[0501] VI. expiration of a Timing Advance Timer (TAT);

[0502] VII. any one or more of the triggering events as described herein may occur, e.g. for another candidate cell than the original triggering candidate cell.

[0503] VIII. one or more of triggering events as described herein has occurred, e.g. for N>1 other candidate cells, in particular after the trigger occurred for the candidate cell in question (i.e. follow one or more of Options l-VIII based on the last N triggers)

[0504] The network may adjust its (conditional) mobility related actions, in particular based on the defined apparatus, e.g. UE, measurement behavior / requirement according to subject-matter as described herein, for example:

[0505] When the apparatus, e.g. the UE, is determined to perform a measurement for a candidate cell / beam:

[0506] - The network may determine to reserve the configured resource(s) (such as CFRA preamble(s), e.g. used for early synchronization procedure or CBRA-based LTM, CG etc.) for conditional cell change for a candidate cell / beam, e.g. for which the apparatus, e.g. the UE, perform a measurement related to a configured conditional cell change condition (and the apparatus, e.g. the UE, may be evaluating the condition); or- The network may send a cell change command, or other mobility related command (such as early DL synchronization command (e.g., TCI state activation command) or early UL synchronization command (e.g., PDCCH order for early TA acquisition), in particular based on measurement(s) the apparatus, e.g. the UE, may be determined to perform (and report).

[0507] When the apparatus, e.g. the UE, is not determined to perform a measurement fora candidate cell / beam:

[0508] - The network may determine to not reserve the configured resource(s) for conditional cell change fora candidate cell / beam, e.g. for which the apparatus, e.g. the UE, is not performing measurement(s) related to a configured conditional cell change condition (and consequently not evaluating the condition), or

[0509] - The network may not send a cell change command, or other mobility related command (such as early DL synchronization command (e.g., TCI state activation command) or early UL synchronization command (e.g., PDCCH order for early TA acquisition), in particular based on configured measurement(s) the apparatus, e.g. the UE, may be not determined to perform (and / or report).

[0510] The subject-matter descried herein may affect a technical standard specification, e.g. a 3rd Generation Partnership Project (3GPP) standard specification in the following way, which is outlined as merely an example, e.g. all features, elements and / or steps which are described should be considered optional and, in particular non-limiting. In particular, the example specification impact to L1 measurement requirements, e.g. in TS 38.133 may be shown for the subject-matter mentioned herein, e.g. Options 1a-6b described above. In this example only the at least one indication as an example triggering event, in particular a TCI state activation command, may be considered as this already exists as an event to change UE L1 measurement behavior in the specification outlined below. Impact of any other triggering event may be captured in a similar manner. The impact on the specification may be exemplarily outlined / reflected as follows (changes, additions and / or amendments may be underlined):Table 9.14.5.1-3: Intra-frequency L1-RSRP measurement period Tintra_ LI-RSRP_Measurement_Reriod_ssB in FR2 for UE incapable of multiCellLI -measRTD-greaterThan-CP-r18

[0517] NOTE: When the number of neighbor cells to be measured on intra-frequency and interfrequency without gap is more than 1 and TCI state(s) of at least one of these neighbor cells is in the active TCI state list, the requirements apply only to the cell(s) that have TCI state(s) is in the active TCI state list and (Option 1a / 3a) to the neighbour cell(s) that are configured with L1 based condition for conditional cell switch / (Option 1b / 3b) neighbour cell(s) for which the UE is configured to evaluate a L1 based condition for conditional cell switch / (Option 2a) to the neighbour cell(s) that are configured with at least one of L1 or L3 based condition for conditional cell switch / (Option 2b) neighbour cell(s) for which the UE is configured to evaluate at least one of L1 or L3 based condition for conditional cell switch.

[0538] Figs. 1A-1B show an example signaling according to subject-matter described herein. In particular, Figs. 2A-2B show an example of. Figs. 2A-2B show an example of, wherein Fig. 1 B may be regarded as a continuation of Fig. 1A, which is why these figures may be commonly described. It should be noted that any reference related to LTM, a specific measurement, a specific condition, a specific trigger, a specific Option 1a-6b, a specific Cell, L1, L3, RRC etc. may be considered optional and, in particular, not limiting. It should be noted that the signaling diagraming according to Figs 1A-1B does not show the different triggers or trigger events as described herein, in particular i) the at least one indication which may indicate that at least one of: a measurement requirement, or a measurement behavior of the apparatus is to be adjusted (e.g. the at least one trigger event / trigger may be a network-initialized trigger event / trigger), and / or ii) (fulfillment of) the at least one measurement-based condition which may indicate thatat least one of: a measurement requirement, or a measurement behavior of the apparatus is to be adjusted (e.g. the at least one trigger event may be based on a trigger condition / trigger included or indicated in the candidate cell configuration). However, the signaling diagram may apply to options i) and / or ii). However, not all of these triggers (a)-f) as outlined below) may be part of the CLTM procedure. The proposed measurement options may be given generally based on any of the triggers. Only the ending option I may be shown in the signal diagram. In the example it may be assumed that both L1- and L3-measurements are configured, e.g. for all candidate cells 1-4. Figs. 1A-1B may be described by the following non-limiting steps:

[0539] Step 1: The apparatus, e.g. the UE may receive, from at least one serving cell of a network, a candidate cell configuration for a conditional cell change procedure which includes or indicates at least one measurement for at least two candidate cells of the network. In other words, the network may send RRC reconfiguration with, e.g. LTM, candidate cell configuration, in particular for Celli, Cell2, Cell3, and Cell4. An Li- based CLTM condition may be configured, e.g. for Celli and Cell2, and a L3-based CLTM condition may be configured for Cell3. No cell change condition may be configured for Cell4, e.g. a cell change can happen to this cell only through a cell change command. The RRC reconfiguration may also contain the measurement configuration for each of Cell 1-4. In this example the measurement configuration may contain configuration for both L1- and L3-based measurements etc.

[0540] Step 2: The apparatus, e.g. the UE, may start performing the, e.g. L1 and L3 based measurements, in particular based on the candidate cell configuration and / or the measurement configuration, e.g. of Stepl, in particular for Cell 1-4. The apparatus, e.g. the UE, may also start evaluating the CLTM cell change conditions, e.g. for Cell 1-3.

[0541] Step 3: After sending the configuration, the network may considerer, e.g. Celli and Cell2, in particular for conditional L1 -based cell change, Cell3 for conditional L3-based cell switch, and / orall cells Celli -Cell4, e.g. for cell change command based cell change. The network may reserve resources in Cell 1 -Cell3 for the time the apparatus, e.g. the UE, is evaluating the conditional cell change condition(s), e.g. for these cells, in particular to prepare the cells for the apparatus, e.g. the UE, to perform potential conditional cell change to these cells.Step 4: The apparatus, e.g. the UE, may either receive at least one indication which may indicate that at least one of: a measurement requirement, or a measurement behavior of the apparatus is to be adjusted or it may determine fulfillment of the at least one measurement-based condition which may indicate that at least one of: a measurement requirement, or a measurement behavior of the apparatus is to be adjusted. This triggering event (e.g. i) or ii)) may occur, e.g. on Celli. The condition / signal that may trigger a changed measurement behavior may be any of the options a)-f) below, which is not distinguished in the signal diagram. The trigger may be, as given in the description:

[0542] a) Condition of event-triggered reporting or DL / UL sync becomes fulfilled for, e.g. Celli;

[0543] b) TCI state activation command for, e.g. Celli;

[0544] c) The apparatus, e.g. the UE may receive a TA acquisition command for, e.g.

[0545] Celli (e.g. PDCCH order);

[0546] d) The apparatus, e.g. the UE, may receive a MAC-CE with TA information for, e.g. Celli;

[0547] e) The apparatus, e.g. the UE, may receivee a command (e.g., MAC CE) activating RS or RS transmission or measurement of a RS for, e.g. Celli ; f) Cell change command for, e.g. Celli .

[0548] The triggering signal may or may not change the UE condition evaluation behavior (e.g. determine that UE starts / stops evaluating some of the configured conditions).

[0549] Step 5: The apparatus, e.g. the UE, may adjust its measurements, e.g. on Cell(s) 1-4, in particular based on the trigger, e.g. for Celli and / or the measurement Options 1a- 6b, that e.g. may apply based on this triggering event.

[0550] In one Example (referred to as Example 1), the determination to perform a measurement may be based on:

[0551] Option 1a: Perform L1 measurement on a candidate cell if configured with L1 condition for this candidate cell; andOption 1b: Perform L3 measurement on a candidate cell if configured with any (L1 or L3 based) cell switch condition for this candidate cell.

[0552] (Otherwise there may be no requirement)

[0553] The apparatus, e.g. UE, measurement behavior after the trigger in Step3 may be: Cell 1 and Cell2 (with L1 condition): Perform L1 and L3 measurement as L1 -based cell change condition may be configured for this cell.

[0554] Cell 3 (with L3 condition): Perform L3 measurement because L3-based cell change condition may be configured for this cell.

[0555] Cell 4 (no condition): There may be no requirement to perform L1 or L3 measurement.

[0556] Step 6: At least partially based on the determination to perform, e.g. L1 and L3 measurements, in particular based on any of the Options 1a-6b, the network may determine to continue or not continue reserving resources, e.g. in Celli -Cell3 for the apparatus, e.g. the UE. Depending on whether the apparatus, e.g. the UE, is to perform measurements, e.g. for any of Celli -Cell4, the network may or may not send a cell change command with these cells as the target cell.

[0557] Using Example 1 in Step5, the network may determine to:

[0558] Cell 1 and Cell 2 (with L1 condition): Reserve resources for the apparatus, e.g. the UE, in these cells for conditional cell change. Consider sending a cell change command for these cells, e.g. based on either L1 or L3 measurements. Cell 3 (with L3 condition): Reserve resources for the apparatus, e.g. the UE, in this cell for conditional cell change. Consider sending a cell change command for this cell, e.g. based on L3 measurements.

[0559] Cell 4: Not send a cell change command for this cell, e.g. as the apparatus, e.g. the UE, may not be expected to perform measurements for this cell.

[0560] Step 7: Based on condition evaluation, e.g. for Celli , apparatus, e.g. the UE, may determine that condition for cell change is fulfilled, met and / or satisfied and / or may start cell change execution, e.g. to Celli.Step 8: The apparatus, e.g. the UE, may execute cell switch, e.g. to Celli. This may also end the measurement behavior, e.g. defined in Step5 in this example (end trigger I).
