Description

[0001] Cross-referencing This disclosure is part of a non-provisional application claiming priority to U.S. Patent Application No. 63 / 516,195, filed July 28, 2023, the contents of which are incorporated herein by reference in their entirety. Technical Field

[0002] This disclosure generally relates to mobile communications, and more specifically, to power headroom reports (PHRs) for user equipment (UE) and network devices in mobile communications for operation of multiple transmission reception points (MTRPs). Background Technology

[0003] Unless otherwise stated in this section, the methods described in this section are not prior art as listed in the following claims and will not be considered prior art by virtue of their inclusion in this section.

[0004] The UE's power headroom report (PHR) is used to report the UE's available power headroom. The PHR can be configured to report periodically or when downlink path loss changes reach a specific amount. For example, the UE can measure a path loss reference signal to determine if the path loss change exceeds a threshold. If so, the UE can be configured to trigger a power headroom report to the network node.

[0005] The types of UE power headroom reports are as follows: Type 1: UE power headroom PH, which is valid for the timing i of a physical uplink shared channel (PUSCH) transmission on an active uplink (UL) bandwidth part (BWP) b of carrier f in serving cell c. Type 3: UE power headroom PH, which is valid for the timing i of a sounding reference signal (SRS) transmission on an active UL BWP b of carrier f in serving cell c. PHR can be actual or virtual, depending on whether an actual PUSCH transmission occurs when the UE reports power headroom. For actual PHR, the power headroom is determined based on actual PUSCH transmissions. For virtual PHR, the power headroom is determined based on reference PUSCH transmissions.

[0006] In New Radio (NR), multi-TRP is introduced to improve reliability, coverage, and capacity performance through flexible deployment scenarios. In MTRP operation, two PHR modes can be configured, one of which can include two PH reports corresponding to different TRPs. In addition, one or more transmission configuration indicator (TCI) states can be indicated for multi-TRP.

[0007] In the current PHR framework of MTRP operation, the UE is configured to calculate a virtual PHR based on some default values. However, this configuration does not take into account the information indicated in the TCI states of multiple TRPs. The reported virtual PHR cannot reflect the correct UE transmission power. The current PHR determination scheme is not accurate enough for MTRP operation with indicated TCI states.

[0008] It is desirable for the UE to be able to determine the power headroom more dynamically and accurately. Therefore, how to improve PHR is an important issue in newly developed wireless communication networks. Therefore, it is necessary to provide appropriate solutions to determine the PHR for MTRP operation. SUMMARY

The invention can be practiced in many different forms and should not be construed as limited to the exemplary embodiments and implementations set forth herein.

In the following description, details of well-known features and techniques may be omitted to avoid unnecessarily obscuring the presented embodiments and implementations.

[0025] Overview Embodiments of this disclosure relate to various techniques, methods, schemes, and / or solutions for PHR (Programmable Response Heading) for MTRP (Multi-Level Processing) operation in relation to a UE (User Equipment) and network apparatus in mobile communications. According to this disclosure, many possible solutions can be implemented individually or in combination. That is, although these possible solutions may be described individually below, two or more of them may be implemented in one or another combination.

[0026] Power margin indicates how much transmission power a UE has remaining beyond its current transmission power consumption. It plays a crucial role in the effective management of uplink transmission power and resource allocation within the network. Essentially, it can be described by the following simple formula.

[0027] Power margin = UE maximum transmission power – PUSCH power The UE can use a Power Headroom Report (PHR) to report its calculated power headroom to the network, allowing the network to adjust the UE's power control and optimize resource allocation. The PHR can be used for UE power control, interference suppression, transmit / receive (TX / RX) settings, and / or network configuration.

[0028] More specifically, a Power Headroom (PHR) can be actual or virtual, depending on whether an actual PUSCH transmission exists when the UE reports power headroom. Whether an actual or virtual PHR is reported is based on uplink transmission scheduling information. For an actual PHR, the power headroom is determined based on actual PUSCH transmissions. For a virtual PHR, the power headroom is determined based on reference PUSCH transmissions (e.g., estimated / calculated power without actual PUSCH transmissions). For example, an actual PHR will be reported for uplink transmissions with configured scheduling information. A virtual PHR will be reported if there is no uplink transmission on the serving cell / carrier.

[0029] If the UE determines that the active type 1 power margin report of the serving cell is based on the actual PUSCH transmission, then for the PUSCH transmission timing i on the active UL BWPb of carrier f of serving cell c, the UE calculates the type 1 power margin report as follows.

[0030] ; , , , , , and Defined in the 3rd Generation Partnership Project (3GPP) technical specifications. It is the power adjustment during PUSCH transmission in the PUSCH transmission time i. It is the maximum output power configured by the UE for the carrier f of the serving cell c during PUSCH transmission time i. It is a component and components The parameters are composed of the sum of these two components, which are provided or predefined by the network, and j∈{0,1,…,J-1}. Configured or predefined by the network. This refers to the bandwidth allocated to PUSCH resources for the PUSCH transmission timing i on the active UL BWP b of carrier f in serving cell c, expressed as the number of resource blocks. It's an SCS configuration. The UE uses the reference signal (RS) index. The downlink path loss estimate calculated for the activated DL BWP of carrier f in serving cell c, in dB. It is the PUSCH power control adjustment state of the activated UL BWP b of carrier f in serving cell c during PUSCH transmission timing i. .

[0031] If the UE determines that the active type 1 PHR of the serving cell is based on the reference PUSCH transmission, then for the PUSCH transmission timing i on the active UL BWP b of the carrier f of the serving cell c, the UE calculates the type 1 power margin report as follows.

[0032] ; Assuming MPR=0 dB, A-MPR=0 dB, P-MPR=0 dB, and DTC=0 dB, calculate... MPR, A-MPR, P-MPR, and DTC are defined in [8-1, TS 38.101-1], [8-2, TS 38.101-2], and [8-3, TS 38.101-3], while other parameters are defined in 3GPP TS. Furthermore, when determining the virtual PHR (i.e., the PHR based on reference PUSCH transmission), some parameters are determined based on default values. For example, using... Obtained by p0-PUSCH-AlphaSetId=0 and The reference is obtained using pusch-PathlossReferenceRS-Id = 0. These values ​​do not take into account the latest power control information from the TRP. A determined virtual PHR may not reflect the actual UE transmission power. Therefore, power control between the UE and the network node may be inaccurate and inefficient.

[0033] For MTRP operation, the UE can be configured with two PHR modes to report multiple PHs for multiple TRPs. The two PHR modes mean that a single report can contain two PHs corresponding to different SRS resource sets. Each SRS resource set can be associated with a TRP. The UE can determine one PH for each TRP. The UE can include two PHs in a single report and send the report containing both PHs to the network side via the control element (CE) of the Media Access Control (MAC). The network side can access the two PHs and assign them to the corresponding TRPs.

[0034] For MTRP operation, the UE can send multiple PUSCH transmissions with the same content to multiple TRPs (e.g., PUSCH duplication). Multiple PHs associated with multiple TRPs can be identified and reported. How multiple PHs are identified can depend on the timing of the uplink transmissions associated with the M-TRP. Figure 1 Example scenarios 101-103 are illustrated under a scheme according to an embodiment of this disclosure. Scenario 101-103 involve at least one UE and two network nodes (e.g., two TRPs), which may be part of a wireless communication network (e.g., an LTE network, a 5G / NR network, an IoT network, or a 6G network). Scenario 101-103 illustrates an example of determining two PHs associated with the two TRPs. The UE can be scheduled for a first PUSCH timing (e.g., a PUSCH timing to TRP1) and a second PUSCH timing (e.g., a PUSCH timing to TRP2). The UE can determine the PH based on whether there is an actual PUSCH transmission at the PUSCH timing.

[0035] If an actual repeat exists in the M-TRP PUSCH repeat within time slot #n, the UE provides a first PHR for the earliest PUSCH repeat (i.e., the actual PHR) in time slot #n, where the PUSCH repeat is associated with an SRS resource set (e.g., TRP1). If another actual PUSCH repeat exists in time slot #n associated with another SRS resource set (e.g., TRP2), the UE provides a second PHR for the first PUSCH repeat (i.e., the actual PHR) associated with the other SRS resource set in time slot #n (Scenario 101). If no PUSCH repeat exists in time slot #n associated with another SRS resource set (e.g., TRP2), the UE provides a second PHR for the reference PUSCH transmission (i.e., the virtual PHR) (Scenario 102). If no actual repeat exists in the M-TRP PUSCH repeat within time slot #n, the UE provides two PHRs for the two reference PUSCH transmissions (i.e., the two virtual PHRs) (Scenario 103).

[0036] The Power Response Rate (PHR) can be determined based on uplink transmissions within a single time slot. Since UE power control can differ across time slots, the PHR can be determined per time slot. Specifically, the UE can determine the PHR based on the start symbol of the PUSCH transmission. In scenario 101, two PUSCH events are scheduled within time slot #n, and the UE should determine the PHR based on both PUSCH events. For example, the UE can determine that the first PH is real and the second PH is real. In scenario 102, although part of the second PUSCH event is in time slot #n+1, the start symbol of the second PUSCH event is within time slot #n, therefore the UE should determine the PHR based on both PUSCH events. For example, the UE can determine that the first PH is real and the second PH is real. In scenario 103, two PUSCH events are scheduled within different time slots (e.g., time slot #n and time slot #n+1), and the UE should determine the PHR based on one PUSCH event within the time slot. For example, the UE can determine that the first PH is virtual and the second PH is virtual.

[0037] Within a unified TCI state framework, a common beam can be indicated for both downlink (DL) and uplink (UL) data and control transmission / reception. For a serving cell configured with a joint DL / UL TCI mode (e.g., unifiedTCI-StateType = "joint"), the entire set or any subset of {first joint TCI state, second joint TCI state} can be mapped to TCI code points in the TCI field of the existing downlink control information (DCI) format 1_1 / 1_2. For a serving cell configured with a separate DL / UL TCI mode (e.g., unifiedTCI-StateType = "separate"), the entire set or any subset of {first DL TCI state, first UL TCI state, second DL TCI state, second ULTCI state} can be mapped to TCI code points in the TCI field of the existing DCI format 1_1 / 1_2. A TCI state activation command (e.g., MAC-CE) should indicate whether each joint / DL / UL TCI state mapped to a TCI code point is the first or second joint / DL / UL TCI state.

[0038] Figure 2 An example TCI state activation method under an embodiment of the present disclosure is illustrated. Table 201 shows TCI state activation for a combined DL / UL TCI mode. "Serving Cell ID = y" and "BWP ID = z" can be used to indicate which serving cell and BWP should be applied to the TCI state activation command. The TCI state activation command can be used to activate the TCI state corresponding to a first TRP, and can be used to activate the TCI state corresponding to a second TRP. Table 202 shows TCI state activation for a separate DL / UL TCI mode. "Serving Cell ID = y" and "BWP ID = z" can be used to indicate which serving cell and BWP should be applied to the TCI state activation command. The TCI state activation command can be used to activate the DL TCI state and UL TCI state corresponding to the first TRP, and can be used to activate the DL TCI state and UL TCI state corresponding to the second TRP, respectively.

[0039] For TCI status indication via DCI, the TCI field in DCI format 1_1 / 1_2 can indicate the combined / DL / UL TCI status of one TRP or two TRPs. For example, DCI format 1_1 / 1_2 can indicate a first indicated TCI status for a first TRP and / or a second indicated TCI status for a second TRP. The UE needs to maintain both the first and second indicated TCI statuses. The TCI field in the DCI can indicate a TCI code point, and the UE can determine the corresponding TCI status from the TCI status mapped to the indicated TCI code point based on the MAC-CE TCI status activation. If only one TCI code point is mapped to a TCI status, no DCI indication is needed after MAC-CE activation; the TCI code point can be "indicated". If the UE receives a beam indication DCI that only indicates the TCI status of one TRP, the UE should update the indicated TCI status for that TRP and maintain the currently indicated TCI status for the other TRP.

[0040] In view of the foregoing, this disclosure proposes several schemes for determining the Power Headroom (PHR) for multiple Transmission Relationships (TRPs) in mobile communications, relating to the UE and network devices. According to the scheme of this disclosure, when determining the PHR for multiple TRPs, the UE needs to consider some UL power control parameters in the indicated TCI state. Different TRPs can be associated with different indicated TCI states, and the UE also needs to maintain multiple indicated TCI states for different TRPs. The UE can use the latest UL power control parameters provided in the indicated TCI state to determine the virtual PHR. Therefore, the UE power margin can be accurately reported to reflect the appropriate / true UE transmit power, thereby improving UE power control.

[0041] Figure 3 An example scenario 300 is illustrated under an embodiment of this disclosure. Scenario 300 involves at least one UE and multiple network nodes (e.g., TRPs), which may be part of a wireless communication network (e.g., an LTE network, a 5G / NR network, an IoT network, or a 6G network). Scenario 300 illustrates a framework for the operation of multiple TRPs in a communication system. The UE may establish connections with a first TRP (e.g., TRP 301) and a second TRP (e.g., TRP 302). The UE is capable of receiving / transmitting control signals and data from at least one first TRP and one second TRP.

[0042] Specifically, the UE can be configured via a higher-level network node configuration (e.g., Radio Resource Control (RRC) configuration) to provide at least two PHR modes and use two SRS resource sets configured for codebook-based or non-codebook-based (e.g., "codebook" or "nonCodebook") transmissions. One SRS resource set can correspond to one TRP. The UE can perform multiple TRP operations based on multiple configured SRS resource sets. When the first PHR is determined to be an actual PUSCH repetition (e.g., the actual PHR) for a PUSCH transmission associated with one SRS resource set, the UE can be configured to provide two Type 1 power headroom reports in slot n. The UE can determine the first PHR based on the actual PUSCH transmission. The first PUSCH transmission can be the earliest starting actual PUSCH repetition associated with one SRS resource set in the slot, and in that slot, the device does not transmit a PUSCH repetition associated with the other SRS resource set. For example, the UE can provide a first Type 1 PHR for the actual PUSCH repetition of the earliest starting PUSCH transmission associated with one SRS resource set in slot n. When the second PHR is determined to be an actual PUSCH repeat associated with another SRS resource set (e.g., the actual PHR), the UE can determine the second PHR based on the actual PUSCH transmission. The first PHR can be determined for the earliest actual PUSCH repeat starting in slot n, and the second PHR can be determined for actual PUSCH repeats overlapping with slot n. For example, if the UE transmits a PUSCH repeat associated with another SRS resource set in slot n, the UE can provide a second type 1 PHR for a first actual PUSCH repeat overlapping with slot n and associated with another SRS resource set.

[0043] When the second PHR is determined to be for a reference PUSCH transmission associated with another SRS resource set (e.g., a virtual PHR), the UE can determine the second PHR based on at least one parameter in the TCI state. The indicated TCI state may include a first indicated TCI state. When the other SRS resource set is a first SRS resource set, the UE can determine the second PHR based on at least one power control parameter and a path loss reference signal associated with the first indicated TCI state. Alternatively, the indicated TCI state may include a second indicated TCI state. When the other SRS resource set is a second SRS resource set, the UE can determine the second PHR based on at least one power control parameter and a path loss reference signal associated with the second indicated TCI state. For example, the UE can provide a second type 1 PHR for a reference PUSCH transmission associated with another SRS resource set. If the other SRS resource set is the first SRS resource set, and the UE is provided with a dl-OrJointTCI-StateList or TCI-UL-State having a first indicated TCI state and a second indicated TCI state, the UE can provide a second type 1 PHR based on the p0AlphaSetforPUSCH and PL-RS associated with the first indicated TCI state. If the other SRS resource set is the second SRS resource set, and the UE is provided with a dl-OrJointTCI-StateList or TCI-UL-State having a first indicated TCI state and a second indicated TCI state, the UE can provide a second type 1 PHR based on the p0AlphaSetforPUSCH and PL-RS associated with the second indicated TCI state.

[0044] In some implementations, the indicated TCI state includes a first indicated TCI state and a second indicated TCI state. When the first PHR is determined to be for a reference PUSCH transmission associated with a first SRS resource set (e.g., a virtual PHR), the UE can determine the first PHR based on at least one power control parameter and a path loss reference signal associated with the first indicated TCI state. When the second PHR is for a reference PUSCH transmission associated with a second SRS resource set (e.g., a virtual PHR), the UE can determine the second PHR based on at least one power control parameter and a path loss reference signal associated with the second indicated TCI state. For example, the UE can provide a Type 1 PHR for the reference PUSCH transmission associated with the first SRS resource set and a Type 1 PHR for the reference PUSCH transmission associated with the second SRS resource set. If the UE is provided with a dl-OrJointTCI-StateList or TCI-UL-State having a first indicated TCI state and a second indicated TCI state, the UE can provide a first type 1 PHR based on p0AlphaSetforPUSCH and PL-RS associated with the first indicated TCI state, and a second type 1 PHR based on p0AlphaSetforPUSCH and PL-RS associated with the second indicated TCI state.

[0045] After determining the first PHR and / or the second PHR, the UE can be configured to send at least one first PHR and one second PHR to the network node.

[0046] In some implementations, if the UE is provided with twoPHRMode on the active UL BWP b of carrier f in serving cell c, and is provided with two SRS resource sets set to "codebook" or "nonCodebook" in srs-ResourceSetToAddModList or srs-ResourceSetToAddModListDCI-0-2, then the UE provides two Type 1 power headroom reports in slot n, wherein: If the UE provides a Type 1 power margin report for the actual PUSCH repetition associated with an SRS resource set that starts earliest in slot n; If the UE transmits a PUSCH repetition associated with another SRS resource set in slot n, the UE provides a Type 1 power margin report for the first actual PUSCH repetition that overlaps with slot n and is associated with another SRS resource set. Otherwise, the UE provides a Type 2 1 power headroom report for reference PUSCH transmissions associated with another SRS resource set, wherein: For Type 1 power margin report and use Obtained by p0-PUSCH-AlphaSetId=0 Obtain it using pusch-PathlossReferenceRS-Id = 0 (if the UE is not provided with enablePL-RS-UpdateForPUSCH-SRS), or Obtain from the PUSCH-PathlossReferenceRS-Id mapped to sri-PUSCH-MappingToAddModList where sri-PUSCH-PowerControlId = 0 (if the UE is provided with enablePL-RS-UpdateForPUSCH-SRS), and ; For Type 2 1 power margin report and use Obtained by p0-PUSCH-AlphaSetId = 1 Obtain it using pusch-PathlossReferenceRS-Id = 1 (if the UE is not provided with enablePL-RS-UpdateForPUSCH-SRS), or obtain it from PUSCH-PathlossReferenceRS-Id mapped to sri-PUSCH-PowerControlId = 0 in sri-PUSCH-MappingToAddModList2. (If the UE is provided with enablePL-RS-UpdateForPUSCH-SRS), and (If the UE is provided with twoPUSCH-PC-AdjustmentStates), or (If the UE is not provided with twoPUSCH-PC-AdjustmentStates); If the UE is provided with dl-OrJointTCI-StateList or TCI-UL-State, and is indicated with a first TCI-State or TCI-UL-State and a second TCI-State or TCI-UL-State, and if the reference PUSCH transmission is associated with the first TCI-State or TCI-UL-State and the second TCI-State or TCI-UL-State respectively, then the UE provides a Type 1 power margin report or a Type 2 power margin report using the p0AlphaSetforPUSCH and pathlossReferenceRS-Id-r17 values ​​associated with the first TCI-State or TCI-UL-State or the second TCI-State or TCI-UL-State respectively.

[0047] In another proposed scheme of this disclosure, MTRP operation may involve non-repeating PUSCH transmissions. The UE can be configured to send different PUSCHs (e.g., different layers of a single PUSCH) to different TRPs (e.g., multi-panel simultaneous transmission schemes). At least one configuration can be provided to the UE via higher-level configurations from network nodes (e.g., RRC configurations): two PHR modes, a multi-panel scheme, two SRS resource sets (using codebook-based or non-codebook-based settings, e.g., "codebook" or "nonCodebook") for transmission, and dl-OrJointTCI-StateList or TCI-UL-State. The UE can be indicated with two TCI states (e.g., a first indicated TCI state and a second indicated TCI state) via MAC-CE or DCI. One SRS resource set can correspond to one TRP. The UE can perform MTRP operations based on multiple configured SRS resource sets. The UE can be configured to provide two Type 1 power headroom reports in time slot n.

[0048] When the first PHR is an actual PUSCH transmission for which only the first indication is applied (e.g., an actual PHR), the UE can determine the first PHR associated with the first indicated TCI state based on the actual PUSCH transmission. When the second PHR is a reference PUSCH transmission for which only the first indication is applied (e.g., a virtual PHR), the UE can determine the second PHR associated with the second indicated TCI state based on at least one parameter in the second indicated TCI state. For example, the UE can provide a first type 1 PHR associated with the first indicated TCI state for an actual PUSCH transmission for which only the first indicated TCI state is applied, and the UE can provide a second type 1 PHR associated with the second indicated TCI state for a reference PUSCH transmission based on p0AlphaSetforPUSCH and PL-RS associated with the second indicated TCI state.

[0049] In some implementations, when the first PHR is determined for a reference PUSCH transmission (e.g., a virtual PHR), the UE can determine the first PHR associated with the first indicated TCI state based on at least one parameter in the first indicated TCI state. When the second PHR is determined for an actual PUSCH transmission using only the second indicated TCI state (e.g., an actual PHR), the UE can determine the second PHR associated with the second indicated TCI state based on the actual PUSCH transmission. For example, the UE can provide a second type 1 PHR associated with the second indicated TCI state for an actual PUSCH transmission using only the second indicated TCI state, and the UE can provide a first type 1 PHR associated with the first indicated TCI state for a reference PUSCH transmission based on p0AlphaSetforPUSCH and PL-RS associated with the first indicated TCI state.

[0050] In some implementations, when the first PHR is the actual PUSCH transmission (e.g., the actual PHR) determining both the TCI state for applying the first indication and the TCI state for applying the second indication, the UE can determine the first PHR associated with the TCI state for the first indication based on the actual PUSCH transmission. When the second PHR is the actual PUSCH transmission (e.g., the actual PHR) determining both the TCI state for applying the first indication and the TCI state for applying the second indication, the UE can determine the second PHR associated with the TCI state for the second indication based on the actual PUSCH transmission. For example, the UE can provide a first type 1 PHR associated with the TCI state for the actual PUSCH transmission applying both indications, and a second type 1 PHR associated with the TCI state for the second indication.

[0051] In some implementations, when the first PHR is determined for a first reference PUSCH transmission (e.g., a virtual PHR), the UE can determine the first PHR associated with the first indicated TCI state based on at least one parameter in the first indicated TCI state. When the second PHR is determined for a second reference PUSCH transmission (e.g., a virtual PHR), the UE can determine the second PHR associated with the second indicated TCI state based on at least one parameter in the second indicated TCI state. For example, the UE can provide a first type 1 PHR associated with the first indicated TCI state for the first reference PUSCH transmission based on p0AlphaSetforPUSCH and PL-RS associated with the first indicated TCI state, and the UE can provide a second type 1 PHR associated with the second indicated TCI state for the second reference PUSCH transmission based on p0AlphaSetforPUSCH and PL-RS associated with the second indicated TCI state.

[0052] After determining the first PHR and / or the second PHR, the UE can be configured to send at least one first PHR and one second PHR to the network node.

For actual PUSCH transmission using a spatial domain filter corresponding only to the second TCI state or TCI-UL state, a second type 1 power headroom report and the maximum output power of the second configuration associated with the second TCI state or TCI-UL state; and for reference PUSCH transmission using p0AlphaSetforPUSCH and pathlossReferenceRS-Id-r17 values ​​associated with the first TCI state or TCI-UL state, a first type 1 power headroom report and the maximum output power of the first configuration associated with the first TCI state or TCI-UL state; For actual PUSCH transmissions using spatial domain filters corresponding to the first TCI state or TCI-UL state and spatial domain filters corresponding to the second TCI state or TCI-UL state, a first type 1 power margin report and a first configuration maximum output power associated with the first TCI state or TCI-UL state, and a second type 1 power margin report and a second configuration maximum output power associated with the second TCI state or TCI-UL state.

[0054] In some implementations, for each TCI state, the uplink power control parameters and the path loss-reference signal (PL-RS) can be provided via RRC configuration. For example, the parameter pathlossReferenceRS-Id-r17 (i.e., ) and ul-powerControl-r17 can be provided in the TCI state of the RRC configuration. ul-powerControl-r17 can include p0AlphaSetforPUSCH-r17.

[0092] Additional Notes The topics described herein sometimes illustrate different components contained within or connected to different other components. It should be understood that the architectures described are merely examples, and many other architectures with the same functionality can actually be implemented. In a conceptual sense, any arrangement of components that achieve the same functionality is effectively “associated” to achieve the desired functionality. Therefore, any two components combined in this document to achieve a particular function can be considered “associated” with each other to achieve the desired functionality, regardless of the architecture or intermediate components. Similarly, any two components so associated can also be considered “operationally connected” or “operationally linked” to each other to achieve the desired functionality, and any two components that can be so associated can also be considered “operationally linked” to each other to achieve the desired functionality. Specific examples of operable connections include, but are not limited to, physically matchable and / or physically interacting components and / or wirelessly interactable and / or logically interacting and / or logically interactable components.

[0093] Furthermore, regarding the use of virtually any plural and / or singular terms in this document, those skilled in the art can appropriately convert from plural to singular and / or from singular to plural depending on the context and / or application. For clarity, various singular / plural permutations may be explicitly described herein.

[0094] Furthermore, those skilled in the art will understand that, in general, the terms used herein, particularly those used in the appended claims, such as the body of the appended claims, are typically intended as “open-ended” terms; for example, the term “comprising” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “at least having,” and the term “comprising” should be interpreted as “including but not limited to.” Those skilled in the art will further understand that if a specific number of introduced claim statements are desired, such an intent will be explicitly stated in the claims, and without such a statement, such an intent does not exist. For example, to aid understanding, the following appended claims may contain the use of the introductory phrases “at least one” and “one or more” to introduce claim statements. However, the use of such phrases should not be construed as implying that a claim statement introduced by the indefinite article "a" or "an" limits any particular claim containing such a claim statement to an embodiment containing only one such statement, even when the same claim includes the introductory phrase "one or more" or "at least one," and indefinite articles such as "a" or "an," e.g., "an" and / or "an," should be interpreted as meaning "at least one" or "one or more." This also applies to the use of explicit texts introducing claim statements. Furthermore, even if a specific number of the introduced claims is explicitly listed, those skilled in the art will recognize that such a list should be interpreted as meaning at least the number listed; for example, a bare list of "two lists" without other modifiers means at least two lists, or two or more lists. Moreover, in those cases, the convention is similar to "at least one of A, B, and C, etc." Generally, in the conventional sense understood by those skilled in the art, the use of such a construct, such as "a system having at least one of A, B, and C," will include, but is not limited to, systems having a single A, a single B, a single C, A and B together, A and C together, B and C together, and / or A, B, and C together, etc., in those cases where the convention is similar to "at least one of A, B, or C." Generally, this construct is intended for use in the conventional sense understood by those skilled in the art; for example, "a system having at least one of A, B, or C" will include, but is not limited to, systems having a single A, a single B, a single C, A and B together, A and C together, B and C together, and / or A, B, and C together. Those skilled in the art will further understand that any extractive words and / or phrases that actually present two or more alternative terms, whether in the specification, claims, or drawings, should be understood to cover the possibility of including one, any, or both of the terms. For example, the phrase "A or B" will be understood to include the possibility of "A" or "B" or "A and B."

[0095] As will be understood from the foregoing, various embodiments of the invention have been described herein for illustrative purposes, and various modifications may be made without departing from the scope and spirit of the invention. Therefore, the various embodiments disclosed herein are not intended to be limiting, and their true scope and spirit are indicated by the appended claims.
