METHODS AND APPARATUS FOR HANDLING INTERRUPTION OF DATA TRANSMISSION AND / OR RECEPTION ON SELECTED CARRIERS IN MOBILE COMMUNICATIONSCROSS REFERENCE TO RELATED PATENT APPLICATION (S)
[0001] The present disclosure is part of a non-provisional application claiming the priority benefit of U.S. Patent Application No. 63 / 772,846, filed 17 March 2025, the content of which herein being incorporated by reference in its entirety.TECHNICAL FIELD
[0002] The present disclosure is generally related to mobile communications and, more particularly, to measurement enhancements for handling interruption of data transmission and / or reception on selected carriers with respect to user equipment in mobile communications.BACKGROUND
[0003] Unless otherwise indicated herein, approaches described in this section are not prior art to the claims listed below and are not admitted as prior art by inclusion in this section.
[0004] In mobile communication systems such as Long-Term Evolution (LTE) and New Radio (NR) , a user equipment (UE) is configured by a network node to perform radio measurements for purposes including mobility management, beam management, and radio resource optimization. To enable such measurements, measurement gaps (MGs) are configured for both downlink (DL) and uplink (UL) operation, during which the UE temporarily interrupts normal data transmission and / or reception in order to perform measurements on target resources that may be located outside the UE’s current operating frequency or bandwidth.
[0005] Measurement gaps are typically configured with a periodic structure and may cause a noticeable interruption of data transmission and reception. For example, with a measurement gap length (MGL) of 6 milliseconds and a measurement gap repetition period (MGRP) of 40 milliseconds, measurement gaps may account for approximately 15%interruption of data transmission and reception. Such interruption may adversely affect throughput, latency, and scheduling efficiency, particularly in scenarios involving carrier aggregation, multi-cell operation, or latency-sensitive services.
[0006] However, throughout the entire measurement gap length, the UE is expected to interrupt data transmission and / or reception on all frequency layers. As a result, all configured carriers, including a primary cell (PCell) and one or more secondary cells (SCells) , are interrupted regardless of whether a particular carrier is actually involved in the measurement operation.
[0007] Such interruption does not differentiate between carriers that are necessary for measurement and carriers that could potentially continue data transmission and / or reception during at least a portion of the measurement gap, particularly during the ML. Moreover, existing approaches do not take into account UE capability, radio frequency resource usage, or whether certain carriers may remain unaffected while measurements are performed. As mobile communication systems continue to evolve toward more complex carrier configurations and dynamic measurement requirements, the impact of measurement interruption becomes increasingly significant, highlighting limitations in existing measurement gap handling mechanisms.SUMMARY
[0008] The following summary is illustrative only and is not intended to be limiting in any way. That is, the following summary is provided to introduce concepts, highlights, benefits and advantages of the novel and non-obvious techniques described herein. Select implementations are further described below in the detailed description. Thus, the following summary is not intended to identify essential features of the claimed subject matter, nor is it intended for use in determining the scope of the claimed subject matter.
[0009] An objective of the present disclosure is to propose solutions or schemes that address the aforementioned issues pertaining to handling measurement interruption with respect to apparatus in mobile communications.
[0010] In one aspect, a method may involve an apparatus interrupting data transmission and / or reception on carriers per-radio frequency (per-RF) or per-band group or per-UE including a PCell and at least one SCell during a radio frequency retuning time (RRT) period of an enhanced measurement gap (E-MG) occasion. The method may also involve the apparatus interrupting data transmission and / or reception on one selected carrier or a set of selected carriers during a measurement length (ML) period of the E-MG occasion. The method may further involve the apparatus reporting to a network node an indication indicating the selected carrier or set of selected carriers to be interrupted during the ML period.
[0011] In another aspect, an apparatus may comprise a transceiver which, during operation, wirelessly communicates with a wireless network. The apparatus may also comprise a processor communicatively coupled to the transceiver. The processor, during operation, may perform operations comprising interrupting data transmission and / or reception on carriers per-radio frequency (per-RF) or per-band group or per-UE including a PCell and at least one SCell during a radio frequency retuning time (RRT) period of an enhanced measurement gap (E-MG) occasion. The processor may also perform operations comprising interrupting data transmission and / or reception on at least one selected carrier during a measurement length (ML) period of the E-MG occasion. The processor may further perform operations comprising reporting, via the transceiver, to a network node an indication indicating the selected carrier or set of selected carriers to be interrupted during the ML period.
[0012] In yet another aspect, a method may involve an apparatus receiving from a user equipment (UE) an indication indicating one selected carrier or a set of selected carriers to be interrupted during a measurement length (ML) period of an enhanced measurement gap (E-MG) occasion. The method may also involve the apparatus scheduling data transmission or reception during the E-MG occasion to the UE on a carrier not indicated to be interrupted.
[0013] It is noteworthy that, although description provided herein may be in the context of certain radio access technologies, networks and network topologies such as LTE, LTE-Advanced, LTE-Advanced Pro, 5G, NR, 5G-Advanced, Internet-of-Things (IoT) , Narrow Band Internet of Things (NB-IoT) , Industrial Internet of Things (IIoT) , beyond 5G (B5G) , and 6th Generation (6G) , the proposed concepts, schemes and any variation (s) / derivative (s) thereof may be implemented in, for and by other types of radio access technologies, networks and network topologies.

[0021] Detailed embodiments and implementations of the claimed subject matters are disclosed herein. However, it shall be understood that the disclosed embodiments and implementations are merely illustrative of the claimed subject matters which may be embodied in various forms. The present disclosure may, however, be embodied in many different forms and should not be construed as limited to the exemplary embodiments and implementations set forth herein. Rather, these exemplary embodiments and implementations are provided so that description of the present disclosure is thorough and complete and will fully convey the scope of the present disclosure to those skilled in the art. In the description below, details of well-known features and techniques may be omitted to avoid unnecessarily obscuring the presented embodiments and implementations. Overview
[0022] Implementations in accordance with the present disclosure relate to various techniques, methods, schemes and / or solutions pertaining to measurement enhancements in mobile communications. According to the present disclosure, a number of possible solutions may be implemented separately or jointly. That is, although these possible solutions may be described below separately, two or more of these possible solutions may be implemented in one combination or another.
[0023] FIG. 1 is a diagram depicting an example scenario 100 under schemes in accordance with implementations of the present disclosure. Scenario 100 involves a user equipment (UE) 110 in wireless communication with a wireless network (e.g., an LTE network, a 5G / NR network, an IoT network or a 6G network) . The UE may connect to the network side. The network side may include one or more network nodes 120. The UE may be a smart phone, a wearable device, an IoT device, and a tablet, etc. Alternatively, the UE may be a notebook (NB) or personal computer (PC) inserted or installed with a data card which includes a modem and radio frequency (RF) transceiver (s) to provide the functionality of wireless communication. The network node may include a base station (BS) which may provide communication coverage for a geographic coverage area where communications with the UE is supported. In one example, the BS may be a Next Generation Node B (gNB) .
[0024] FIG. 2 is a diagram depicting an example scenario 200 under schemes in accordance with implementations of the present disclosure. Scenario 200 involves an example enhanced measurement gap (E-MG) occasion and the overall behavior of a UE during the E-MG occasion. As shown in FIG. 2, the E-MG occasion comprises a radio frequency retuning time (RRT) period and a measurement length (ML) period. The RRT period and the ML period are temporally consecutive, and in some implementations, the E-MG occasion further includes two RRT periods with the ML period therebetween.
[0025] In this embodiment, the UE interrupts data transmission and / or reception on carriers within per-radio frequency (per-RF) or per-band group or per-UE including a PCell and at least one SCell during the RRT period. The interruption during the RRT period enables the UE to retune its radio frequency (RF) circuitry from a serving frequency to a target frequency associated with a measurement configuration. Such RF retuning may include switching an RF circuitry, adjusting a local oscillator, reconfiguring filters, or stabilizing analog front-end circuitry. Due to hardware constraints, the UE may not be able to maintain uplink or downlink transmission during the RRT period.
[0026] During the ML period, the UE performs measurement operations on one or more reference signals, such as synchronization signal blocks (SSBs) or channel state information reference signals (CSI-RSs) . Unlike the RRT period, the UE does not interrupt data transmission and / or reception on all carriers during the ML period. Instead, the UE interrupts data transmission and / or reception only on at least one selected carrier that is impacted by the use of RF circuitry for measurement. Other carriers, including the PCell or one or more SCells, may continue data transmission and / or reception during the ML period. Accordingly, during the ML period, the UE interrupts data transmission and / or reception only on at least one selected carrier, rather than on all carriers.
[0027] In some implementations, the UE determines the selected carrier based on one or a combination of UE capability, one or more measurement object configurations received from the network node, and one or more band combination configurations received from the network node. The one or more measurement object configurations may specify one or more reference signals (e.g., SSB) to be measured, frequency locations of the reference signals, and associated measurement purposes. The UE evaluates whether the measurement requires RF retuning or borrowing of RF circuitry that is currently used for data transmission and / or reception on a carrier. Based on this evaluation, the UE determines which carrier is impacted by the measurement and could be selected for interruption during the ML period.
[0028] After determining the selected carrier, the UE reports an indication / information indicating the selected carrier to the network node. The reported information may indicate which bands, or uplink (UL) and / or downlink (DL) carriers, or UL and / or DL cells are to be interrupted during the ML period. In some cases, the UE indicates whether data transmission and / or reception on the PCell are interrupted during the ML period, or whether data transmission and / or reception on a selected carrier of an SCell are interrupted.
[0029] FIG. 3 illustrates a diagram depicting an example scenario 300 under schemes in accordance with implementations of the present disclosure. Scenario 300 involves multiple carriers used in UE. The UE has multiple carriers configured, including carriers f1-f5, in which the carriers f1 and f2 are used for data transmission (Tx) and reception (Rx) on a PCell and an SCell, and the carriers f3-f5 are used for data reception (Rx) on SCells. The carrier f6 is associated with a measurement object (MO) to be measured. In an event that the UE determines that the measurement requires borrowing a used RF circuitry, for instance, an RF circuitry currently used for Rx operation on the SCell at the frequency of a carrier f5, the UE initiates an enhanced measurement gap (E-MG) operation. During a radio frequency retuning time (RRT) period of the E-MG occasion, the UE interrupts data transmission and / or reception on all carriers f1-f5 of the PCell and SCells. This full interruption during the RRT period enables the UE to retune and stabilize the RF circuitry without maintaining concurrent data transmission or reception.
[0030] After the RRT period, the UE performs measurement operations on reference signals associated with the measurement object configured at a frequency of a carrier f6 during the ML period of the E-MG occasion. To enable reception of the reference signals at the frequency of the carrier f6, the UE borrows the RF circuitry previously used for Rx operation on the SCell at the frequency of carrier f5 and retunes the borrowed RF circuitry to the frequency of carrier f6.
[0031] In this embodiment, only the carrier f5 is selected as a carrier to be interrupted during the ML period. That is, data transmission and / or reception on the carrier f5 are interrupted during the ML period, while data transmission and / or reception on other carriers, including carriers f1-f4 of the PCell or other SCells, may continue during the ML period. The carrier f6 is used by the UE to receive reference signals specified by the measurement object for performing the measurement.
[0032] Accordingly, the UE determines that the carrier f5 is a selected carrier to be interrupted during the ML period, based on the fact that the RF circuitry originally associated with carrier f5 is borrowed for measurement at carrier f6. The UE reports an indication indicating the selected carrier f5 to the network node, such as by indicating that the carrier f5 is to be interrupted during the ML period. In some implementations, the UE further reports a correspondence between the measurement object associated with the carrier f6 and the selected carrier f5.
[0033] In other implementations, the selected carrier to be interrupted during the measurement length (ML) period is not limited to the carrier f5 used for reception on an SCell. Depending on UE capability, carrier configuration, and measurement object requirements, different carriers f1-f4 of the PCell and SCells may be selected for interruption during the ML period.
[0034] In some implementations, the UE determines that the carrier f1 associated with transmission and reception on a PCell is to be interrupted during the ML period. The UE selects the carrier f1 as the selected carrier to be interrupted during the ML period, and reports the information selection to the network node.
[0035] In some implementations, the UE determines that one or more carriers f2-f4 associated with transmission and reception on one or more SCells are to be interrupted during the ML period. In such cases, the UE may select a single SCell carrier or multiple SCell carriers as the selected carrier (s) or set of selected carriers to be interrupted, based on which radio frequency circuitry is required for performing the measurement associated with a measurement object.
[0036] In these implementations, the UE determines the selected carrier based on which carrier’s radio frequency circuitry is borrowed or otherwise impacted for measurement, and reports an indication indicating the selected carrier to the network node. On the network side, the network node receives the indication indicating at least one selected carrier to be interrupted during the ML period of an E-MG occasion. Based on the received information, the network node schedules data transmission or reception to the UE on carriers that are not indicated to be interrupted during the ML period. The network node may further receive an indication indicating a need for interruption or an E-MG and correspondence information between measurement objects and selected carriers of SCells. Accordingly, interruption during the ML period can be flexibly applied to a carrier of the PCell or to one or more carriers of SCells, while other carriers continue data transmission and / or reception during the ML period.
[0037] The UE enables selective interruption of data transmission and / or reception during the ML period, such that only the one or more selected carriers are interrupted. This embodiment illustrates that, although all carriers may be interrupted during the RRT period, interruption during the ML period can be limited to one or more selected carriers, thereby reducing unnecessary interruption of data transmission and / or reception on other carriers.
[0038] In some implementations, the UE performs measurements for measuring resources outside an active bandwidth part (BWP) . Such measurements may require RF retuning and therefore may trigger the selective interruption mechanisms described herein.
[0039] The measurements may include Layer-1 (L1) measurements, such as measuring reference signal received power (RSRP) , signal-to-interference-plus-noise ratio (SINR) , and reference signal received quality (RSRQ) , for serving cells or neighboring cells. Alternatively, the measurements may include Layer-3 (L3) measurements, such as intra-frequency, inter-frequency, or inter-radio access technology measurements. In some implementations, when the UE performs L1 measurements (e.g., L1 Reference Signal Received Power (L1-RSRP) , L1 Signal-to-Interference-plus-Noise Ratio (L1-SINR) , Radio Link Monitoring (RLM) , Beam Failure Detection (BFD) , or Candidate Beam Detection (CBD) ) for a serving cell, such as a PCell, a Primary Secondary Cell (PSCell) , and / or a SCell, on resources configured for L1 measurements either within or outside the operating channel bandwidth, and the UE may need to perform Radio Frequency (RF) retuning, which may cause interruption on transmission and / or reception, then the UE may not interrupt control channels (e.g., Downlink (DL) control channel and / or Uplink (UL) control channel) , such as the Hybrid Automatic Repeat reQuest Acknowledgment (HARQ-ACK) and the Physical Downlink Control Channel (PDCCH) including the Downlink Control Information (DCI) .
[0040] The UE may further report a correspondence between measurement objects and a selected carrier of an SCell to be interrupted during the ML period. For example, the UE may indicate that when performing a measurement associated with a specific measurement object, a particular SCell will be interrupted. The UE may determine the selected carrier of the SCell based on factors including one or more band combination configurations of the UE, a frequency location of a synchronization signal block specified in the measurement object (s) , a band containing the SCell, a status of the SCell being activated or deactivated, and a center frequency of the synchronization signal block contained in the SCell.
[0041] In some implementations, the UE determines whether to interrupt control channels and / or data channels during the ML period based on a combination of the selected carrier determination and the location of reference signals relative to the operating channel bandwidth. In some cases, when reference signals specified by a measurement object are determined to be within the operating channel bandwidth, the UE determines not to interrupt control channels and selectively determines whether to interrupt data channels on the selected carrier. The UE reports an indication corresponding to no-gap and / or no-interruption to the network node, thereby allowing continued transmission of control information while measurements are performed.
[0042] In other cases, when reference signals specified by the measurement object are determined to be outside the operating channel bandwidth, the UE determines that radio frequency retuning is required and that interruption may be necessary. In such cases, the UE determines the selected carrier of the SCell to be interrupted during the ML period based on at least one of one or more band combination configurations of the UE, a frequency location of a synchronization signal block specified in the measurement object (s) , a band containing the SCell, a status of the SCell being activated or deactivated, and a center frequency of the synchronization signal block contained in the SCell. The UE reports an indication corresponding to the interruption to the network node, so that the UE can utilize the interruption to retune radio frequency circuitry and perform measurements on resources located outside the operating channel bandwidth.
[0043] In some implementations, when L3 measurements are performed for neighboring cells on measurement resources configured on a frequency layer different from that of the serving cell, the UE determines that RF retuning is required and that interruption may occur. In such cases, the UE may determine not to interrupt control channels carrying downlink control information or uplink control information, while selectively interrupting data channels on the selected carrier. In other implementations, when reference signals of the serving cell and the target neighboring cell are determined to have the same center frequency, the UE may determine that no interruption is required and report corresponding indications to the network node.
[0044] In some implementations, when reference signals of the serving cell and the target neighboring cell are determined to have different center frequencies, the UE may determine whether interruption is required and, if so, apply interruption during a limited period before and after a measurement occasion. The interruption may be applied according to an interruption length, interruption ratio, or interruption location, and may be scheduled to avoid overlapping with control channel resources. In this manner, the UE determines and applies interruption behavior during the ML period in coordination with selected carrier determination, while preserving critical control signaling and reducing unnecessary interruption of data transmission and reception.
[0045] In some implementations, when the UE is allowed to report whether interruption is required, the UE may perform an L1 or L3 measurement according to an interruption location for cell (s) (e.g., serving cell and / or neighboring cell) on resources configured by the network node outside the operating channel bandwidth. The UE may report the requirement for the interruption when necessary.
[0046] In some implementations, when the indication indicates that an interruption is required, the UE may perform an RF re-tuning to measure an L1 measurement. In other words, the UE may transmit a report indicating a requirement for interruption to perform the RF re-tuning, such as enlarging its operating bandwidth or changing the operating bandwidth to another frequency layer, in order to perform the L1 measurements (e.g., L1-RSRP, L1-SINR, and L1-RSRQ measurements) .
[0047] In some implementations, when the indication indicates that an interruption is required, the UE may perform at least one of an RLM measurement, a BFD measurement, and a CBD measurement. In other words, the UE may transmit a report for the requirement of interruption to perform the RLM, BFD, and / or CBD measurements.
[0048] In some implementations, the UE may perform measurements for a serving cell including a PCell, a PSCell, and / or an SCell.
[0049] In some implementations, the indication may be reported after a Radio Resource Control (RRC) re-configuration, a DCI or a Media Access Control-Control Element (MAC-CE) . In particular, the RRC re-configuration, DCI, or MAC-CE may provide new measurement configurations or scheduling information that determine the time-frequency resources to be measured. Accordingly, the UE may transmit the interruption indication only after receiving such signaling, since the requirement for interruption depends on the updated measurement configuration and the associated operating bandwidth.
[0050] In some implementations, an L3 reporting capability may be extended to support L1 measurement reporting. In other words, the existing reporting capability of L3 may be extended to enable the UE to report L1 level measurement information (such as interruption requirements or measurement results associated with reference signals) through an L3 signaling procedure (e.g., an RRC message) . Such an extension may be implemented without introducing a new UE capability, by reusing existing reporting information elements (IEs) or report formats, or with a new UE capability, by defining additional fields or signaling parameters to explicitly indicate the UE’s L1 measurement or interruption-reporting behavior.
[0051] In some implementations, the UE may report to the network node that the UE may maintain control channel continuity (i.e., no data channel interruption) . In other words, the UE may report to the network that the UE may not interrupt the control channel.
[0052] In some implementations, the UE may determine whether to interrupt a control channel and / or data channel depending on the UE’s capability. In particular, the determination may depend on whether the UE supports simultaneous communication and measurement operations, dual-receiver architecture, or an extended bandwidth capability. A UE having sufficient hardware resources or dual-RF capability may perform measurements without interruption, whereas a UE with limited capability may require temporary interruption to perform the measurement.

Illustrative Processes
[0060] FIG. 5 illustrates an example process 500 in accordance with an implementation of the present disclosure. Process 500 may be an example implementation of above scenarios / schemes, whether partially or completely, with respect to measurement enhancements in mobile communications. Process 500 may represent an aspect of implementation of features of communication apparatus 410. Process 500 may include one or more operations, actions, or functions as illustrated by one or more of blocks 510, 520 and 530. Although illustrated as discrete blocks, various blocks of process 500 may be divided into additional blocks, combined into fewer blocks, or eliminated, depending on the desired implementation. Moreover, the blocks of process 500 may be executed in the order shown in FIG. 5 or, alternatively, in a different order. Process 500 may be implemented by communication apparatus 410 or any suitable UE (e.g., the UE) or machine type devices. Solely for illustrative purposes and without limitation, process 500 is described below in the context of communication apparatus 410 as a UE. Process 500 may begin at block 510.
[0061] At block 510, process 500 may involve processor 412 of communication apparatus 410 interrupting data transmission and / or reception on carriers per-radio frequency (per-RF) or per-band group or per-UE including a PCell and at least one SCell during a radio frequency retuning time (RRT) period of an enhanced measurement gap (E-MG) occasion. Process 500 may proceed from block 510 to block 520.
[0062] At block 520, process 500 may involve processor 412 interrupting data transmission and / or reception on one selected carrier or a set of selected carriers during a measurement length (ML) period of the E-MG occasion. Process 500 may proceed from block 520 to block 530.
[0063] At block 530, process 500 may involve processor 412 reporting to a network node (e.g., as represented by network apparatus 420) an indication indicating the selected carrier or set of selected carriers to be interrupted during the ML period.
[0064] In some implementations, the indication indicating the selected carrier or set of selected carriers to be interrupted may include an indication of which bands, or uplink (UL) and / or downlink (DL) carriers, or UL and / or DL cells are to be interrupted during the ML period.
[0065] In some implementations, the indication indicating the selected carrier or set of selected carriers to be interrupted may include an indication of whether the data transmission and / or reception on the carriers of the PCell are interrupted during the ML period.
[0066] In some implementations, the indication indicating the selected carrier or set of selected carriers to be interrupted may include an indication of whether the data transmission and / or reception on the carriers of the at least one SCell are interrupted during the ML period.
[0067] In some implementations, the ML period has a duration sufficient to receive one or more reference signals.

Additional Notes
[0084] The herein-described subject matter sometimes illustrates different components contained within, or connected with, different other components. It is to be understood that such depicted architectures are merely examples, and that in fact many other architectures can be implemented which achieve the same functionality. In a conceptual sense, any arrangement of components to achieve the same functionality is effectively "associated" such that the desired functionality is achieved. Hence, any two components herein combined to achieve a particular functionality can be seen as "associated with" each other such that the desired functionality is achieved, irrespective of architectures or intermedial components. Likewise, any two components so associated can also be viewed as being "operably connected" , or "operably coupled" , to each other to achieve the desired functionality, and any two components capable of being so associated can also be viewed as being "operably couplable" , to each other to achieve the desired functionality. Specific examples of operably couplable include but are not limited to physically mateable and / or physically interacting components and / or wirelessly interactable and / or wirelessly interacting components and / or logically interacting and / or logically interactable components.
[0085] Further, with respect to the use of substantially any plural and / or singular terms herein, those having skill in the art can translate from the plural to the singular and / or from the singular to the plural as is appropriate to the context and / or application. The various singular / plural permutations may be expressly set forth herein for sake of clarity.
[0086] Moreover, it will be understood by those skilled in the art that, in general, terms used herein, and especially in the appended claims, e.g., bodies of the appended claims, are generally intended as “open” terms, e.g., the term “including” should be interpreted as “including but not limited to, ” the term “having” should be interpreted as “having at least, ” the term “includes” should be interpreted as “includes but is not limited to, ” etc. It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases "at least one" and "one or more" to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles "a" or "an" limits any particular claim containing such introduced claim recitation to implementations containing only one such recitation, even when the same claim includes the introductory phrases "one or more" or "at least one" and indefinite articles such as "a" or "an, " e.g., “a” and / or “an” should be interpreted to mean “at least one” or “one or more; ” the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should be interpreted to mean at least the recited number, e.g., the bare recitation of "two recitations, " without other modifiers, means at least two recitations, or two or more recitations. Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc. ” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention, e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and / or A, B, and C together, etc. In those instances where a convention analogous to “at least one of A, B, or C, etc. ” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention, e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and / or A, B, and C together, etc. It will be further understood by those within the art that virtually any disjunctive word and / or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B. ”
