SIGNALING, RULES AND USER EQUIPMENT BEHAVIORS FOR SEPARATE CSI REPORTING IN SUBBAND FULL-DUPLEXING IN MOBILE COMMUNICATIONSCROSS REFERENCE TO RELATED PATENT APPLICATION (S)
[0001] The present disclosure claims the priority benefit of Indian Patent Application No. 202421011040, filed 16 February 2024, 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 signaling, rules and user equipment (UE) behaviors for separate channel state information (CSI) reporting in subband full-duplexing (SBFD) in mobile communications.BACKGROUND
[0003] In wireless communications such as mobile communications under the current 3rd Generation Partnership Project (3GPP) specification, the evolution of wireless communication technologies has been characterized by continuous advancements aimed at enhancing data rates, reducing latency, and increasing network capacity. Full-duplex communication, which enables simultaneous transmission and reception on the same frequency channel, has emerged as a promising solution within the realm of evolving wireless networks. Subband Full Duplex (SBFD) is at the forefront of addressing the ever-increasing demand for high-speed, low-latency wireless connectivity. In its essence, full-duplex communication allows a wireless device to transmit and receive data simultaneously on the same frequency band, effectively doubling the available bandwidth and improving spectral efficiency. This stands in contrast to traditional communication systems, which employ half-duplex operation, where a device can either transmit or receive data at a given moment. The promise of full-duplex operation lies in its potential to revolutionize wireless communication by mitigating the limitations of half-duplex systems, such as increased latency and reduced network capacity.
[0004] The SBFD system takes full-duplex communication a step further by utilizing a subband allocation approach. Instead of transmitting and receiving on the entire frequency band, this system divides the available spectrum into smaller subbands, with each subband allocated for specific transmission and reception tasks. The main benefits of SBFD include the support for low latency (round-trip time) and larger coverage. The availability of more frequent Downlink (DL) and Uplink (UL) resources can effectively reduce the latency for both DL and UL transmissions. Typically, UL coverage is the bottleneck in the network. By employing the repetition of UL data in consecutive or more frequent UL resources, the UL coverage can be significantly increased, addressing this bottleneck, and enhancing network performance.
[0005] While SBFD provides flexibility and offers more efficiency for the wireless system, it also poses new challenges, particularly in channel state information estimation, due to the potential additional interferences. These challenges require innovative solutions to ensure the effective implementation and performance of SBFD in wireless communication systems. Therefore, there is a need for a solution of signaling, rules and UE behaviors for separate CSI reporting in SBFD in mobile communications.SUMMARY

[0020] 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
[0021] Implementations in accordance with the present disclosure relate to various techniques, methods, schemes and / or solutions pertaining to signaling, rules and UE behaviors for separate CSI reporting in SBFD 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.
[0022] FIG. 1 illustrates an example network environment 100 in which various solutions and schemes in accordance with the present disclosure may be implemented. FIG. 2 ~ FIG. 8 illustrate examples of implementation of various proposed schemes in network environment 100 in accordance with the present disclosure. The following description of various proposed schemes is provided with reference to FIG. 1 ~ FIG. 8.
[0023] Referring to FIG. 1, network environment 100 may involve a UE 110, such as a mobile device or smartphone, in wireless communication with a wireless network 120 as part of a communication network. The wireless network 120 may be one or more public land mobile networks (PLMNs) including, for example, 5G / NR domain and / or 4G / LTE domain. UE 110 may initially be in wireless communication with wireless network 120 via a base station or network node 125 (e.g., an eNB, gNB or transmit-receive point (TRP) ) . In network environment 100, UE 110 and the wireless network 120 may implement various schemes pertaining to signaling, rules and UE behaviors for separate CSI reporting in SBFD in mobile communications in accordance with the present disclosure, as described herein.
[0024] It is noteworthy that, while the various proposed schemes may be individually or separately described below, in actual implementations some or all of the proposed schemes may be utilized or otherwise implemented jointly. Of course, each of the proposed schemes may be utilized or otherwise implemented individually or separately. Moreover, as used herein, a lower layer may refer to a layer in the 5GMM protocol stack that is lower than the radio resource control (RRC) layer, such as a packet data convergence protocol (PDCP) layer, a radio control link (RLC) layer, a medium access control (MAC) layer, a physical (PHY) layer, or so forth.
[0025] FIG. 2 illustrates an example scenario 200 under a proposed scheme in accordance with the present disclosure. Scenario 200 may pertain to SBFD frame structures, with a frame structure with a DUD configuration shown in part (A) of FIG. 2 and a frame structure with a DU configuration shown in part (B) of FIG. 2. Referring to part (A) of FIG. 2, in the SBFD frame structure with DUD, the frequency allocation consists of a downlink slot, an uplink slot, and another downlink slot, with a guard band in between. Referring to part (B) of FIG. 2, in the SBFD frame structure with DU, the frequency allocation consists of a downlink slot and an uplink slot, with a guard band in between. These SBFD frame structures represent different types of time-domain slots within the SBFD frame structure.
[0026] The slots of time-domain slots within the SBFD frame structure are categorized as follows: (1) DL-only (D) slot or DL-non-partitioned slot, (2) UL-only (U) slot or UL-non-partitioned slot, and (3) SBFD (X) slot DL-partitioned slot. In the DL-only (D) slot or DL-non-partitioned slot, the frequency resources are available only in the downlink direction, enabling downlink transmission exclusively. The UL-only (U) slot or UL-non-partitioned slot provides frequency resources that are available only in the uplink direction, facilitating uplink transmission exclusively. The SBFD (X) slot DL-partitioned slot features frequency resources that are shared in both the downlink and uplink directions, allowing for simultaneous transmission and reception within the same slot. This configuration represents the essence of Subband Full Duplex, where bidirectional communication occurs within a single slot, enhancing spectral efficiency and capacity.
[0027] FIG. 3 illustrates an example scenario 300 under a proposed scheme in accordance with the present disclosure. Scenario 300 may pertain to SBFD deployment examples. Specifically, the exemplary SBFD deployment scenarios may include a single-cell SBFD scenario, shown in part (A) of FIG. 3, as well as a multi-cell SBFD scenario, shown in part (B) of FIG. 3. In SBFD, several types of interference can occur, including: (1) gNB Self-Interference, (2) UE-UE Cross-Link Interference (CLI) , and (3) gNB-gNB CLI. The gNB Self-Interference is a type of interference that occurs when a gNB's own transmitted signal interferes with its own received signal. In SBFD That is, when the gNB simultaneously transmits and receives on the same frequency band, self-interference can occur due to imperfections in isolation between the transmit and receive paths. The UE-UE CLI occurs when the transmission from one UE interferes with the reception of another UE. In SBFD, where UEs are simultaneously transmitting and receiving on the same slot, cross-link interference can occur due to the proximity and concurrent activities of multiple UEs. The gNB-gNB CLI refers to the interference between different gNBs in the network. In SBFD, where gNBs are simultaneously transmitting and receiving on the same slot, cross-link interference can occur between neighboring gNBs due to the proximity and concurrent activities of multiple gNBs.
[0028] Table 1 below provides a comprehensive description of all the interferences present in single-cell and multi-cell SBFD scenarios, offering valuable insights into the interference landscape within these deployment scenarios. Table 1: Interference in SBFD scenarios
[0029] In a SBFD network, various entities may be assumed, including SBFD-capable gNB (s) , SBFD-capable UE (s) , SBFD-aware UE (s) , and SBFD-unaware UE (s) . In the present disclosure, a SBFD-capable gNB refers to a gNB that can support full duplexing and utilize the SBFD feature. Additionally, a SBFD-capable UE denotes a UE that can support full duplexing and utilize the SBFD feature. Moreover, a SBFD-aware UE denotes a UE that is unable to support full duplexing but is aware of the SBFD feature. Furthermore, a SBFD-unaware UE denotes a UE that cannot support full duplexing and is unaware of the SBFD feature.
[0030] It is noteworthy that SBFD configuration signaling from the gNB cannot be read or understood by SBFD-unaware UEs. As a result, SBFD-unaware UEs cannot be scheduled for UL transmissions in the SBFD slots and are unable to enjoy the benefits of the SBFD feature. This distinction in signaling and scheduling may impact the ability of SBFD-unaware UEs to leverage the advantages of SBFD, highlighting the importance of SBFD awareness and support for optimal network performance.
[0031] FIG. 4 illustrates an example scenario 400 under a proposed scheme in accordance with the present disclosure. Scenario 400 may pertain to general signaling flow of downlink transmissions, detailing the various signaling and processing at both a gNB (e.g., network node 125) and a UE (e.g., UE 110) . In 5G NR mobile communications, the DL flow typically involves various Radio Resource Control (RRC) signaling for CSI report configuration and CSI resource configuration. These configurations are essential for the accurate reporting and utilization of CSI in the downlink direction. The RRC signaling for CSI report configuration and CSI resource configuration includes certain key aspects, including: (1) CSI Report Configuration, (2) CSI Resource Configuration, (3) RRC Signaling, (4) UE Processing, and (5) CSI Reporting. Regarding CSI Report Configuration, the gNB configures the UE with CSI report configurations, specifying the parameters and settings for reporting channel state information. This includes the periodicity, format, and details of the CSI reports to be transmitted by the UE to the gNB. Regarding CSI Resource Configuration, the gNB configures the UE with CSI resource configurations, specifying the resources and settings for measuring and reporting channel state information. This includes the allocation of specific resources for CSI-RS (CSI Reference Signals) and other reference signals used for channel estimation and reporting. Regarding RRC Signaling, the gNB transmits RRC signaling to the UE to convey the CSI report configuration and CSI resource configuration parameters. This signaling includes the setup, modification, and release of CSI reporting and measurement configurations based on the network requirements and conditions. Regarding UE Processing, the UE processes the received RRC signaling to configure its CSI reporting and measurement parameters accordingly. This involves setting up the periodicity, frequency, and other details for CSI reporting and measurement based on the gNB's instructions. Regarding CSI Reporting, based on the configured CSI report and resource configurations, the UE performs CSI measurements and reports the channel conditions back to the gNB using the specified CSI-RS and reference signals. Overall, the RRC signaling for CSI report configuration and CSI resource configuration enable the gNB to configure the UE with the necessary parameters for accurate and efficient reporting of channel state information in the downlink direction, facilitating advanced beamforming, multiple-input-multiple-output (MIMO) , and interference management in 5G NR.
[0032] The interference patterns exhibit differences between DL-only slots and DL resources of SBFD slots. In DL-only slots, DL reception is impacted by co-channel interference (CCI) , which arises from the simultaneous transmission of multiple signals on the same frequency channel. On the other hand, DL reception on DL resources of SBFD slots is additionally affected by UE-UE inter / intra subband CLI, which stems from the concurrent transmission and reception activities of User Equipment (UE) within the same or adjacent subbands.
[0033] Because of these distinct interference patterns, the CSI estimated on DL-only slots cannot be utilized for DL resources on SBFD slots, and vice versa, during scheduling and link adaptation. This limitation arises from the unique interference characteristics experienced in each slot type, necessitating separate CSI estimation, and reporting to accurately capture the interference environment and optimize link adaptation for both DL-only and SBFD slots.
[0034] FIG. 5 illustrates an example scenario 500 under a proposed scheme in accordance with the present disclosure. Scenario 500 may pertain to various options of separate CSI reporting for DL-only slots and DL resources of SBFD slots (e.g., Option 1, Option 2, Option 3 and Option 4) . In Option 1, the gNB signals to the UE two CSI Report Configurations. The first CSI Report Configuration is associated with SBFD slots / symbols, and the second is associated with non-SBFD slots / symbols. The first CSI Report Configuration is linked to a CSI-RS restricted to SBFD slots / symbols only, while the second CSI Report Configuration is linked to a CSI-RS restricted to non-SBFD slots / symbols only.
[0035] In Option 2, the gNB signals to the UE two CSI Report Configurations. The first CSI Report Configuration is associated with SBFD slots / symbols, and the second is associated with non-SBFD slots / symbols. Both CSI Report Configurations are associated with the same CSI-RS. The CSI report associated with one CSI Report Configuration is derived based on CSI-RS instances in SBFD slots / symbols only, and the CSI report associated with the second CSI Report Configuration is derived based on CSI-RS instances in non-SBFD slots / symbols only.
[0036] In Option 3, the gNB signals to the UE a single CSI Report Configuration. The CSI Report Configuration associated with both SBFD slots / symbols and non-SBFD slots / symbols. The CSI Report Configuration is associated with two CSI-RSs restricted to SBFD slots / symbols and non-SBFD slots / symbols, resulting in separate CSI measurements derived from each CSI-RS.
[0037] In Option 4, the gNB signals to the UE a single CSI Report Configuration. The CSI Report Configuration associated with both SBFD slots / symbols and non-SBFD slots / symbols. The CSI Report Configuration is associated with a single CSI-RS, and the CSI report is derived based on the CSI-RS, which can be in SBFD slots / symbols or non-SBFD slots / symbols in different time instances.
[0038] To enable the support of separate DL CSI for DL resources of SBFD slots and DL-only slots, 5G NR requires additional signaling, new rules, and behavior for UE 110. This includes the introduction of distinct CSI reporting configurations, signaling methods, and UE behaviors to accurately capture and report channel state information for both SBFD and non-SBFD slots.
[0039] In view of the above, to enable the support of separate DL CSI for DL resources of SBFD slots and DL-only slots, a base station such as gNB (e.g., network node 125) may signal separate CSI report configurations for DL resources of SBFD slots and DL-only slots to a UE (e.g., UE 110) , with each CSI report configuration being associated with a unique CSI resource configuration. The gNB may signal a new parameter 'slot type' as part of the CSI report configuration, and the 'slot type' parameter may take one of two option, namely: (1) partitioned slot or SBFD slot, and (2) non-partitioned slot or non-SBFD slot or DL-only slot. The CSI resource configuration may implicitly indicate the ‘slot type’ based on the association of the CSI report configuration and CSI resource configuration. The CSI resource configuration may explicitly indicate the ‘slot type’ parameter, and the 'slot type' parameter may take one of two options, namely: (1) partitioned slot or SBFD slot, and (2) non-partitioned slot or non-SBFD slot or DL-only slot.
[0040] Correspondingly, the UE may adhere to certain guidelines to ascertain the validity of CSI-RS. For instance, with respect to CSI-RS validity of CSI-ResourceConfig for partitioned slot / SBFD slot, if the UE identifies the CSI-RS instance in a partitioned slot, it may be considered valid, and the UE may proceed with the measurements and estimation. Moreover, if the UE identifies the CSI-RS instance in a non-partitioned slot, it may be considered invalid, and the UE may refrain from conducting the measurements and estimation. With respect to CSI-RS validity of CSI-ResourceConfig for non-partitioned slot / DL-only slot, if the UE identifies the CSI-RS instance in a non-partitioned slot, it may be considered valid, and the UE may proceed with the measurements and estimation. On the other hand, if the UE identifies the CSI-RS instance in a partitioned slot, it may be considered invalid, and the UE may refrain from conducting the measurements and estimation. Table 2 provides the above rules to be followed by the UE to determine the validity of CSI-RS. Table 2: Rules to determine the validity of CSI-RS
[0041] Regarding the behavior of a SBFD-aware UE in case such SBFD-aware UE identifies the CSI-RS as invalid, the SBFD-aware UE may not process the CSI-RS for CSI measurements. Moreover, the SBFD-aware UE may use the CSI-RS for physical downlink shared channel (PDSCH) rate-matching if the SBFD-aware UE is scheduled with some resources on the same slot.
[0042] To enable the support of separate DL CSI for DL resources of SBFD slots and DL-only slots, the base station or gNB may signal a single CSI report configuration to the UE, with the CSI report configuration being associated with one or two CSI resource configurations. For instance, the gNB may signal a new parameter 'slot type' as part of the CSI report configuration, and the 'slot type' parameter may take one of two options, namely: (1) Partitioned slot or SBFD slot, and (2) non-partitioned slot or non-SBFD slot or DL-only slot. The CSI resource configuration may implicitly indicate the ‘slot type’ based on the CSI-RS instance on the slot. Further, the gNB may configure the measurement restrictions to UE to realize accurate CSI measurement and report.
[0043] Under a first proposed scheme in accordance with the present disclosure, a gNB (e.g., network node 125) may perform certain operations pertaining to signaling, rules and UE behaviors for separate CSI reporting in SBFD in mobile communications. Under the proposed scheme, the gNB may signal a first new parameter ‘timeRestrictionOfSameSlotTypeForChannelMeasurements’ in CSI-ReportConfig. This first new parameter may take the following two options: (1) configured and (2) notConfigured. Here, ‘configured’ may denote that a UE (e.g., UE 110) is to derive the channel measurements for computing CSI based on only a non-zero power (NZP) CSI-RS of the most recent slot, and ‘notConfigured’ may denote that the UE is to derive the channel measurements for computing CSI based on the NZP CSI-RS of multiple slots, with the multiple slots being of a same slot type. Under the proposed scheme, this first new parameter may be valid only if the parameter ‘timeRestrictionForChannelMeasurements’ in CSI report configuration is set as notConfigured. On the other hand, this first new parameter may not exist if the parameter ‘timeRestrictionForChannelMeasurements’ is set as configured. Moreover, if the parameter 'timeRestrictionForChannelMeasurements' is configured, the first new parameter may take a low priority and become invalidated.
[0044] Under the proposed scheme, the gNB (e.g., network node 125) may, alternatively or additionally, signal a second new parameter ‘timeRestrictionOfSameSlotTypeForInterferenceMeasurements’ in CSI-ReportConfig, and this second new parameter may take the following two options: (1) configured and (2) notConfigured. Here, ‘configured’ may denote that a UE (e.g., UE 110) is to derive the interference measurements for computing CSI based on only the NZP CSI-RS and / or CSI-IM (Channel State Information Interference Measurement) of the most recent slot, and ‘notConfigured’ may denote that the UE is to derive the interference measurements for computing CSI based on the NZP CSI-RS and / or CSI-IM of multiple slots, with the multiple slots being of a same slot type. Under the proposed scheme, this second new parameter may be valid only if the parameter ‘timeRestrictionForInterferenceMeasurements’ in CSI report configuration is set as notConfigured. On the other hand, this second new parameter may not exist if the parameter ‘timeRestrictionForInterferenceMeasurements’ is set as configured. Furthermore, if the parameter timeRestrictionForInterferenceMeasurements’ is configured, the second new parameter may take a low priority and become invalidated.
[0045] Under a second proposed scheme in accordance with the present disclosure, a gNB (e.g., network node 125) may perform certain operations pertaining to signaling, rules and UE behaviors for separate CSI reporting in SBFD in mobile communications. Under the proposed scheme, the gNB may signal a third new parameter ‘timeRestrictionForChannelMeasurementsR19’ in CSI-ReportConfig, and this third new parameter may take the following three options: (1) configured, (2) notConfigured, and (3) sameSlotType. Here, ‘configured’ may denote that a UE (e.g., UE 110) is to derive the channel measurements for computing CSI based on only the NZP CSI-RS of the most recent slot. Additionally, ‘notConfigured’ may denote that the UE is to derive the channel measurements for computing CSI based on the NZP CSI-RS of multiple slots. Moreover, ‘sameSlotType’ may denote that the UE is to derive the channel measurements for computing CSI based on the NZP CSI-RS of multiple slots, with the multiple slots being of a same slot type. Under the proposed scheme, this third new parameter may take the top priority and invalidate ‘timeRestrictionForChannelMeasurements’ for SBFD-aware UEs in CSI report configuration.
[0046] Under the proposed scheme, the gNB (e.g., network node 125) may, alternatively or additionally, signal a fourth new parameter ‘timeRestrictionForInterferenceMeasurementsR19’ in CSI-ReportConfig, and this fourth new parameter may take the following three options: (1) configured, (2) notConfigured, and (3) sameSlotType. Here, ‘configured’ may denote that a UE (e.g., UE 110) is to derive the interference measurements for computing CSI based on only the NZP CSI-RS or the CSI-IM of most recent slot. Additionally, ‘notConfigured’ may denote that the UE is to derive the interference measurements for computing CSI based on the NZP CSI-RS or the CSI-IM of multiple slots. Furthermore, ‘sameSlotType’ may denote that the UE is to derive the interference measurements for computing CSI based on the NZP CSI-RS or the CSI-IM of multiple slots, with the multiple slots being of a same slot type. Under the proposed scheme, this fourth new parameter may take a top priority and invalidate ‘timeRestrictionForInterferenceMeasurements’ for SBFD-aware UEs in CSI report configuration.
[0047] As an implementation example, under one or more of the proposed schemes in accordance with the present disclosure, network node 125 may signal two CSI report configurations and two CSI-RS resource configurations to a SBFD-aware UE (e.g., UE 110) , with one for SBFD symbols / slots and another for non-SBFD symbols / slots. Network node 125 may configure explicitly the valid symbol type for each CSI report. UE 110 may determine the validity of CSI-RS based on the CSI-RS instance (whether in SBFD symbols or non-SBFD symbols) and the valid symbol type provided by network node 125. In an event that UE 110 finds the valid CSI-RS for the required CSI report, UE 110 may proceed to measure the CSI and report the measurement result to network node 125.
[0048] Under the proposed schemes, network node 125 may transmit two CSI report configurations to UE 110, with a first configuration of the two CSI report configuration being applicable to one or more symbols of DL-only or DL-non-partitioned type, and with a second configuration of the two CSI report configuration being applicable to one or more symbols of SBFD or DL-partitioned type. Additionally, network node 125 may transmit a respective symbol using one or more CSI-RS resources corresponding to either or both of the two CSI report configurations to UE 110. In response, network node 125 may receive two CSI reports from UE 110. The CSI reports may be associated with CSI-RS resources across SBFD symbols and non-SBFD symbols in different slots. Moreover, each of the CSI-RS resources within a slot may have either all SBFD or all non-SBFD symbols. Additionally, the CSI reporting may be based on at least one of the following: (a) separate CSI reporting for SBFD symbols and non-SBFD symbols; and (b) same CSI reporting for SBFD symbols and non-SBFD symbols.
[0049] Under the proposed schemes, UE 110 may receive two CSI report configurations from network node 120, with a first configuration of the two CSI report configuration being applicable to one or more symbols of DL-only or DL-non-partitioned type, and with a second configuration of the two CSI report configuration being applicable to one or more symbols of SBFD or DL-partitioned type. UE 110 may also receive a respective symbol from one or more CSI-RS resources corresponding to each of the two CSI report configurations from network node 125. In response, UE 110 may determine the validity of the CSI-RS resources based on the CSI-RS instance. UE 110 may also measure the CSI based on the valid CSI-RS resource (s) . UE 110 may further transmit a CSI report, based on the CSI report configuration, to network node 125. Illustrative Implementations

[0074] 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.
[0075] 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.
[0076] 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. ”
