METHODS AND APPARATUSES FOR RELAXATION IN TRANSMITTER EMISSIONS OR RECEIVER BLOCKING REQUIREMENTS

CROSS REFERENCE TO RELATED PATENT APPLICATION (S)

The present disclosure is part of a non-provisional application claiming the priority benefit of U.S. Patent Application No. 63/505, 456, filed on 1 June 2023, U.S. Patent Application No. 63/507,482, filed 12 June 2023, and U.S. Patent Application No. 63/598,981, filed 15 November 2023. The contents of aforementioned applications are herein incorporated by reference in their entirety.

TECHNICAL FIELD

The present disclosure is generally related to mobile communications and, more particularly, to relaxation in transmitter emissions or receiver blocking requirements with respect to user equipment (UE) and network apparatus in mobile communications.

BACKGROUND

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.

In wireless radio access systems, such as Long-Term Evolution (LTE) and New Radio (NR) , uplink (UL) performance is traditionally a bottleneck to overall performance, due to the limited transmission power available at the mobile device (or called UE) . As short bursty data becomes more prominent, techniques are being developed to allow higher peak transmission power for different device types, while still fulfilling those traditional regulatory and equipment design obligations. However, in LTE and NR systems, one bottleneck that limits how much the transmission power can be increased is the need for the UE to comply with the transmitter emissions requirements defined by 3^rd generation partnership project (3GPP) standards. These requirements are developed by 3GPP as the result of extensive analysis, with values of parameters for those requirements normally chosen considering a scenario where two mobile network operators (MNOs) deploy their BS sites and adjacent channels such that they are “non-co-located” to the worst level possible, i.e., where the cell edge of Operator A’s channel is co-located with the base station (BS) site location of Operator B’s channel, as shown in FIG. 1. Similarly, in downlink (DL) direction, there is a need to meet receiver blocking requirements which constrain the reception capability of the UE. The receiver blocking requirements are traditionally also driven by adjacent channel performance in the same scenario as for the transmitter emissions requirements in UL direction.

It is observed that a UE is allowed to reduce its output power in order to comply with the transmitter emissions requirements. However, the reduction in UE transmission output power will cause the link performance drop in UL direction (i.e., the user data rate will decrease) or cause a more limited range at which the UE can deliver data signal to the network (i.e., the UE may be unable to deliver or receive any data signal from the network) . Alternatively, without such an allowance for output power reduction, the UE may consume more energy in order to achieve the same output power performance while complying with the transmitter emissions requirements, and this may be detrimental to the user experience because the UE battery may discharge faster, leading to more frequent recharge being required.

Therefore, there is a need to provide proper schemes to solve the aforementioned issues associated with the transmitter emissions and/or receiver blocking requirements.

DETAILED DESCRIPTION OF PREFERRED IMPLEMENTATIONS

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

Implementations in accordance with the present disclosure relate to various techniques, methods, schemes and/or solutions pertaining to relaxation in transmitter emissions or receiver blocking requirements. 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.

In LTE and NR systems, to comply with the transmitter emissions and/or receiver blocking requirements, a UE may suffer from link performance drop, limited delivery range, and battery power drain as described above. Generally, these issues come from the fact that the transmitter emissions or receiver blocking requirements are defined according to the assumption of non-co-located deployments between operators in adjacent spectrum (i.e., BS sites of different operators are not assumed to be co-located or shared in the same location) , and the need to protect adjacent operator deployments from unacceptable interference. However, these interference issues may not exist to the same degree in different scenarios of adjacent operator deployment (e.g., the scenario where BS sites deployed by operators of adjacent spectrum are collocated/shared) .

In view of the above, the present disclosure proposes a number of schemes pertaining to relaxation in transmitter emissions or receiver blocking requirements. Specifically, the network node (e.g., BS) may transmit a signaling (e.g., via broadcast or dedicated signaling) to the UE to indicate a relaxation in transmitter emissions requirements and/or receiver blocking requirements, and the UE may apply relaxed transmitter emissions requirements for an UL transmission (optionally, the relaxed transmitter emissions requirements may be associated to tighter/decreased MPR requirements to increase maximum output power level) , or apply relaxed receiver blocking requirements for a DL reception. Additionally, or optionally, the UE may transmit capability information to the network node, wherein the capability information indicates that the UE supports the relaxation in the transmitter emissions requirements and optionally the corresponding ability to tighten MPR requirements and increase in maximum transmitted output power level, or supports the relaxation in the receiver blocking requirements. The transmitter emissions requirements may include the out-of-band emission requirements and/or the spurious emission requirements that are defined in 3GPP standards (e.g., 3GPP technical specification (TS) 38.101-1) . The receiver blocking requirements may include the out-of-band blocking requirements and/or the adjacent channel selectivity (ACS) requirements that are defined in 3GPP standards (e.g., 3GPP TS 38.101-1) . By relaxing the transmitter emissions requirements, the UE may decrease the MPR for UL transmissions (e.g., based on the relaxed transmitter emissions requirements) and therefore increase its maximum transmitted power level. Similarly, by relaxing the receiver blocking requirements, the UE may increase the required utilized spectrum within an operating channel of the UE (e.g., based on the relaxed receiver blocking requirements) . Accordingly, by applying the schemes of the present disclosure, the same level of output power reduction is not required for the UE, and the UL data rate and coverage for the UE can be improved (e.g. depending on the modulation scheme and waveform, a UE operating in the edge resource blocks (RBs) may have an improved UL performance by up to 1.5dB if the MPR was able to be tightened/decreased) . Furthermore, by applying the schemes of the present disclosure, the power consumption of the UE may be reduced for the same coverage and link performance.

It is noteworthy that the proposed schemes of the present disclosure are applicable for the scenario of co-located adjacent operator deployment, as well as the scenario where the operator’s operating spectrum block is wider than the UE’s allocated spectrum block, but the present disclosure is not limited thereto. For example, the proposed schemes of the present disclosure may also be applicable for the scenario of non-co-located adjacent operator deployment or in the case of a Non- Terrestrial Network deployment where near-far interference effects are less of an issue when compared to terrestrial deployments (due to the distance between UE and satellite) , and where spectrum may be partitioned even by the same operator (e.g. frequency reuse factor > 1) .

FIG. 2 illustrates an example scenario 200 of co-located adjacent operator deployment in accordance with an implementation of the present disclosure. Scenario 200 involves two networks of different MNOs (denoted as Operator A and Operator B) in adjacent operating channels, and the radio access network (RAN) site is shared between the MNOs (i.e., the BSs of different MNOs are co-located) . In particular, there is a strong drive from MNOs for cost reduction, as revenue growth has slowed at least in some regions of the world. RAN site acquisition is a major cost factor, and this has led to initiatives such as selective site sharing among MNO competitors, e.g., in rural and suburban areas. This trend is expected to grow further in the future, possibly with whole RAN infrastructure being shared between MNO competitors. As this trend grows, one can anticipate that the traditional coexistence modelling performed by 3GPP in setting the transmitter emissions and receiver blocking requirements will no longer be the only relevant scenario to consider. As such, relaxation in transmitter emissions requirements and/or receiver blocking requirements may be applied in the scenario of co-located adjacent operator deployment.

FIG. 3 illustrates an example scenario 300 of operator spectrum block wider than UE spectrum block in accordance with an implementation of the present disclosure. Scenario 300 involves an MNO holding the license for a wider spectrum block than the spectrum block allocated to a UE, and the MNO operates the whole spectrum block from the same network site. As such, relaxation in transmitter emissions requirements and/or receiver blocking requirements may be applied for the UE outside of the allocated spectrum block, since the adjacent spectrum is still within the overall block used by the same operator.

In telecommunications standards such as 3GPP, the out-of-band emission requirements are normally defined directly from the edge of the channel bandwidth of the UE. 3GPP standards are an example of this whereby 3GPP TS 38.101-1 clause 6.5 defines the transmitter emissions requirements by parameters, including occupied bandwidth, spectrum emission mask (SEM) , adjacent channel leakage ratio (ACLR) , and spurious emissions. FIG. 4 illustrates an example scenario 400 of existing out-of-band and spurious emissions requirements in current 3GPP standards. Scenario 400 depicts the existing out-of-band and spurious emissions requirements for 3GPP NR UE operating in a 20MHz channel bandwidth, with the aforementioned parameters being defined symmetrically relative to the lower edge and the upper edge of the “channel bandwidth” allocated to the UE.

More specifically, regarding the transmitter emissions requirements, ACLR is the ratio of the filtered mean power centered on the assigned channel frequency to the filtered mean power centered on an adjacent channel frequency. The spectrum emission mask of the UE applies to frequencies (Δf_OOB) starting from the ± edge of the assigned NR channel bandwidth. For frequencies offset greater than Δf_OOB, the spurious emission requirements in clause 6.5.3 of TS 38.101-1 are applicable. The out-of-band emission requirements lead to the permitted use of MPR by the UE, whereby the UE is permitted to reduce its maximum transmission power, when operating in certain uplink frequency resources (e.g., resource blocks (RBs) ) , to allow the UE to achieve the out-of-band emission requirements such as ACLR and SEM (i.e., the out-of-band emission requirements are associated with SEM and ACLR) . As defined in TS 38.101-1 (e.g., Table 6.2.2-1: MPR for power class 3) , it is shown that higher MPR is allowed towards the edge frequency resources (e.g., RBs) of the UL operating channel. Moreover, regarding the receiver blocking requirements, ACS is a measure of a receiver's ability to receive an NR signal at its assigned channel frequency in the presence of an adjacent channel signal at a given frequency offset from the center frequency of the assigned channel. Specifically, ACS is the ratio of the receive filter attenuation on the assigned channel frequency to the receive filter attenuation on the adjacent channel (s) .

Under a first proposed scheme of the present disclosure, a virtual channel bandwidth may be defined/configured to relax the transmitter emissions requirements and tighten/decrease the MPR needed at both edges of the channel bandwidth used by the UE. This channel bandwidth is virtual because the UE may not have the capability to actually transmit on such a wide channel bandwidth (i.e., the virtual channel bandwidth is larger than the maximum channel bandwidth supported by the UE) . In particular, the virtual channel bandwidth is defined for the purpose of establishing the reference and boundary for out-of-band emission requirements and spurious emissions, which is more relaxed than if it was applied to the 20MHz channel bandwidth directly. FIG. 5 illustrates an example scenario 500 of virtual channel bandwidth configuration for the out-of-band/spurious emission requirements in accordance with an implementation of the present disclosure. Scenario 500 depicts a 20MHz channel bandwidth being contained within a 40MHz virtual channel bandwidth. In one example, the network may transmit a configuration to the UE to indicate the 40MHz virtual channel bandwidth and the center frequency of the virtual channel bandwidth, even though the UE would actually only transmit across a maximum of 20MHz channel bandwidth. In the example, this configuration creates a 10MHz gap at both sides of the actually used 20MHz channel bandwidth. The created gaps leave more margin for the UE to perform UL transmission with higher power (i.e., the MPR is tightened/decreased compared to nominal standardized values) , while applying the out-of-band emission requirements and the spurious emission requirements with a 10MHz shift and with the out-of-band emission requirements scaling according to a 40MHz channel bandwidth reference. Of course, other virtual bandwidth sizes are possible, and the center point of the virtual bandwidth may not be equal to the center point of the channel bandwidth, hence leaving different and possibly asymmetrical gaps at each side of the UE channel bandwidth. Similarly, the virtual channel relaxation scheme may also be applied in the out-of-band blocking and/or ACS requirements to create a similar gap at both sides of the actually used 20MHz channel bandwidth, such that the UE may perform DL reception with more required utilized spectrum (e.g., orthogonal frequency-division multiplexing (OFDM) subcarriers) within the UE’s operating channel, compared to nominal standardized values.

Under a second proposed scheme of the present disclosure, a frequency-shifted out-of-band/spurious emission requirements may be defined/configured to relax the transmitter emissions requirements and tighten/decrease the MPR needed at both edges of the channel bandwidth used by the UE. This proposed scheme is similar to the first proposed scheme (i.e., using a virtual channel bandwidth) , in that it is defined for the purpose of establishing the reference and boundary for out-of-band emission requirements and spurious emissions, which is more relaxed than if it was applied to the 20MHz channel bandwidth directly. However, in this proposed scheme, beyond the shifted boundary from the channel edge, the out-of-band emission requirements are defined with respect to the channel bandwidth actually used by the UE. FIG. 6 illustrates an example scenario 600 of frequency-shifted out-of-band/spurious emission requirements in accordance with an implementation of the present disclosure. Scenario 600 depicts a 20MHz channel bandwidth with the reference and boundary of the out-of-band emission requirements shifted by 10MHz away from the channel edge. In one example, the network may transmit a configuration to the UE to indicate the frequency-shifted out-of-band/spurious emission requirements (i.e., to indicate a frequency shift at one or both edges of a channel bandwidth of the UE for the transmitter emissions requirements and/or the receiver blocking requirements) . This configuration creates a 10MHz gap at both edges of the actually used 20MHz channel bandwidth. The created gaps leave more margin for the UE to perform UL transmission with higher power (i.e., the MPR is tightened/decreased compared to nominal standardized values) , while applying the out-of-band emission requirements and the spurious emission requirements with a 10MHz shift and with the out-of-band emission requirements scaling according to a 20MHz channel bandwidth reference. As with the virtual bandwidth, other gap sizes for the shift are possible, and may not be symmetrical on both sides of the UE channel bandwidth. Similarly, the frequency-shifted relaxation scheme may also be applied in the out-of-band blocking and/or ACS requirements to create a similar gap at both sides of the actually used 20MHz channel bandwidth, such that the UE may perform DL reception with more required utilized spectrum (e.g., OFDM subcarriers) within the UE’s operating channel, compared to nominal standardized values.

Under a third proposed scheme of the present disclosure, a one-side relaxed out-of-band/spurious emission requirements may be defined/configured to relax the transmitter emissions requirements and tighten/decrease the MPR needed at both edges of the channel bandwidth used by the UE. In a typical OFDM system, it is possible that the entire channel bandwidth is not transmitted by the UE, and as defined in 3GPP TS 38.101-1, this is called the “transmission bandwidth configuration” and often called “partial RB allocation” . In this case, if the allocation of transmission resources has an implicit guardband within the channel to the edge of the channel bandwidth, then it would be possible for the UE to perform UL transmission with higher power and not require relaxations in the transmitter emissions requirements on one-side of the channel, but the UE would require such a guardband on the side that is closer to the transmitted resources. FIG. 7 illustrates an example scenario 700 of one-side relaxed out-of-band/spurious emission requirements in accordance with an implementation of the present disclosure. Scenario 700 depicts an approximately 10MHz of transmission resources (in red) within a 20MHz channel bandwidth. The left edge of the channel does not need the 10MHz shift described in the second proposed scheme of the present disclosure, because there is already a 10MHz gap between the first transmitted frequency resource and the left edge of the channel. However, at the right edge, the relaxation in out-of-band/spurious emission requirements is required. In one example, the network may transmit a configuration to the UE to indicate the one-side relaxed out-of-band/spurious emission requirements (i.e., to indicate a channel bandwidth where the UE is only allocated with a partial RB allocation of the channel bandwidth) . As shown in FIG. 7, the solution of frequency-shifted out-of-band/spurious emission requirements may be applied to create a 10MHz gap at the right edge of the channel. The limitation here is that the one-sided relaxation can only apply when the UE is allocated with a partial RB allocation of transmission bandwidth compared to the configured channel bandwidth. Alternatively, the one-side relaxed out-of-band/spurious emission requirements may be realized by applying the solution of virtual channel bandwidth configuration to create a gap at the right edge of the channel. In one example, the network may transmit a configuration to the UE to indicate the one-side relaxed out-of-band/spurious emission requirements, where corresponding MPR tightening/decreasing may only apply if the UE is allocated with a partial RB allocation of the channel bandwidth. FIG. 8 illustrates an example scenario 800 of one-side relaxed out-of-band/spurious emission requirements in accordance with another implementation of the present disclosure. Scenario 800 depicts a 30MHz virtual channel bandwidth applied around a 20MHz channel bandwidth, with a 10MHz gap created inside the channel due to the partial RB allocation, and another gap outside of the channel (i.e., the gap at the right edge) enabled via the out-of-band emission requirements relaxation with scaling according to a 30MHz channel bandwidth reference. In one example, the network may transmit a configuration to the UE to indicate the one-side relaxed out-of-band/spurious emission requirements (i.e., to indicate a channel bandwidth larger than a maximum channel bandwidth supported by the UE, where corresponding MPR tightening/decreasing may only apply if the UE is allocated with a partial RB allocation of the maximum channel bandwidth) . Similarly, the one-side relaxation scheme may also be applied in the out-of-band blocking and/or ACS requirements to create a 10MHz gap at one side of the actually used 20MHz channel bandwidth, such that the UE may perform DL reception with more required utilized spectrum (e.g., OFDM subcarriers) within the UE’s operating channel, compared to nominal standardized values.

Considering the scenario where the operator’s operating spectrum block is wider than the UE’s allocated spectrum block, it can be expected that if there is sufficient gap between the channel bandwidth actually used by the UE and the edge of the spectrum block provided by the operator, then relaxation in the transmitter emissions may be applied without causing harmful interference outside of the spectrum block where the channel bandwidth actually used by the UE is in. The same would apply for relaxed receiver blocking requirements with the gap helping the UE receiver’s ability to block interference from the adjacent spectrum when the relaxed receiver blocking applied. FIG. 9 illustrates an example scenario 900 of frequency-shifted out-of-band/spurious emission requirements with operator spectrum block wider than UE spectrum block in accordance with an implementation of the present disclosure. Scenario 900 depicts the frequency-shifted out-of-band/spurious emission requirements, with a 10MHz gap created at both edges of the actually used 20MHz channel bandwidth. In particular, the left gap is located between the channel bandwidth actually used by the UE and the edge of the spectrum block provided by the operator. The drawback of configuration is that there needs to be a gap between the spectrum block edge and the allocated channel, which leaves less freedom for deployment flexibility of the 20MHz channel. Alternatively, in order to overcome this drawback, the one-side relaxed out-of-band/spurious emission requirements can be applied. FIG. 10 illustrates an example scenario 1000 of one-side relaxed out-of-band/spurious emission requirements with operator spectrum block wider than UE spectrum block in accordance with an implementation of the present disclosure. Scenario 1000 depicts a 20MHz channel bandwidth allocated at the edge of the spectrum block of the operator, wherein the UE is only allocated with a partial RB allocation of 51 RBs (approximately 10MHz) to the right side of the 20MHz channel bandwidth. Both of the implementations in FIGs. 9 and 10 allow the UE to transmit with higher power due to relaxed transmitter emissions requirements, without causing more interference outside of the spectrum block than it normally would, thereby enabling the proposed schemes of the present disclosure for relaxing transmitter emissions and/or receiver blocking requirements in certain operating scenarios.

Overall, the level of allowed relaxation in the transmitter emissions and/or receiver blocking requirements, as well as the potential tightening/decrease of the MPR requirements and/or potential increase in required utilized spectrum, may depend on the frequency location of resources (e.g. RBs in NR) transmitted by the UE within its operating bandwidth, and the proximity in frequency of the channel bandwidth to the edge of a licensed spectrum block.

In some implementations, the relaxed transmitter emissions and/or receiver blocking requirements, and the tightened MPR requirements and/or the increase in required utilized spectrum may be specified in 3GPP standard (s) (e.g., TS 38.101-1) . For example, in 3GPP standard (s) , one or more entries may be added in one or more tables for specifying the values of parameters associated with the relaxed transmitter emissions and/or receiver blocking requirements and the tightened MPR requirements and/or the increase in required utilized spectrum.

In some implementations, the tightening/decrease of MPR requirements may only apply to outer physical RB and/or edge physical RB allocations within the channel.

In some implementations, the signaled configuration may only be applicable in the serving cell, and optionally other cells with the same carrier frequency.

In some implementations, the relaxation in transmitter emissions (and optionally the tightening/decrease in MPR requirements) and/or receiver blocking requirements may be applied only in certain operating conditions of the UE. For example, the certain conditions may include at least one of: (i) a radio condition, such as the pathloss from the BS site, (ii) a transmission power level, such as above a certain power level threshold, (iii) the UE is operating within a certain defined time window, and (iv) the level of UL/DL interference in the operating channel of the UE or in the adjacent channel (e.g., such information may be exchanged between network nodes) . Additionally, or optionally, the certain conditions may be signaled to the UE from the network.

In some implementations, the relaxation in transmitter emissions (and optionally the tightening/decrease in MPR requirements) and/or receiver blocking requirements may be applied only in certain operating conditions of the network, such as (i) the adjacent channel is sharing a site with the channel in which the UE is operating, (ii) the UE is configured with a smaller channel than operated by the network and operating at a certain spectral distance from the edge of that spectrum block.

In some implementations, the relaxation in transmitter emissions (and optionally the tightening/decrease in MPR requirements) and/or receiver blocking requirements may be applied only to a UE of certain characteristics differentiated from other types of defined device. For example, the relaxation in transmitter emissions (and optionally the tightening/decrease in MPR requirements) and/or receiver blocking requirements may be applied only to a reduced capability (RedCap) UE or an enhanced RedCap (eRedCap) UE (e.g., as defined in 3GPP Release 17 and later specifications) .

Additional Notes

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.

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.

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., “asystem 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., “asystem 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.
