[0001] CROSS REFERENCE TO RELATED PATENT APPLICATION (S)
[0002] The present disclosure is part of a non-provisional application claiming the priority benefit of U.S. Patent Application No. 63 / 505,775, filed 02 June 2023 and U.S. Patent Application No. 63 / 508,293, filed 15 June 2023, the contents of which herein being incorporated by reference in their entirety.TECHNICAL FIELD
[0003] The present disclosure is generally related to mobile communications and, more particularly, to power saving in device collaborative communications with respect to primary user equipment (UE) , collaborating UE and network apparatus in mobile communications.BACKGROUND
[0004] 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.
[0005] Massive multiple-input multiple-output (MIMO) technology plays a crucial role in boosting spectral efficiency and signal robustness in fifth generation (5G) New Radio (NR) . With the evolution of practical antenna systems, accommodating large numbers of antenna ports at a network node becomes feasible from an implementation standpoint.
[0006] Although the MIMO enhancement has been achieved at the network side, physical hardware limitation at the user equipment (UE) side is still a bottleneck for MIMO gain improvement. To improve the overall MIMO performance at the UE side, device collaborative communications have been proposed.
[0007] Device collaborative communications involve a relay operation performed by a collaborating device to relay a radio frequency (RF) signal between the network node and a primary device. However, the relay operation may cause extra power consumption at the collaborating device and / or the primary device.
[0008] Accordingly, how to boost MIMO performance with the consideration of power saving becomes an important issue in the newly developed wireless communication network. Therefore, there is a need to provide proper schemes to reduce power consumption in device collaborative communications.SUMMARY

[0031] DETAILED DESCRIPTION OF PREFERRED IMPLEMENTATIONS
[0032] 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.
[0033] Overview
[0034] Implementations in accordance with the present disclosure relate to various techniques, methods, schemes and / or solutions pertaining to power saving in device collaborative 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.
[0035] FIG. 1 illustrates an example scenario 100 of a mobile communications network to implement device collaboration in accordance with implementations of the present disclosure. A personal area network (PAN) may support extended reality (XR) -like services, such as XR glasses with a mobile phone (e.g., a UE) or a customer premises equipment (CPE) . A public network may comprise one or more repeaters and a mobile phone. In some implementations, at least one device may be a collaborating device or a collaborating communication apparatus to facilitate augmentation in transceiving capability (e.g., antenna capability, diversity, rank, or others) of a primary device or a primary communication apparatus in the mobile communications network.
[0036] FIG. 2 illustrates an example scenario 200 of diversity augmentation based on device collaboration in accordance with implementations of the present disclosure. A high-capability device (e.g., a smartphone or a UE) may serve as a proxy to provide a good-quality data path for a low-capability device (e.g., XR glasses) . In this device collaboration scenario, the high-capability device may be a collaborating communication apparatus or a collaborating UE and the low-capability device may be a primary communication apparatus or a primary UE. A device-control path CTRL may be established between the primary UE and the collaborating UE to exchange control signaling or critical information, including channel state information (CSI) , repeater-mode enabling, power control etc.
[0037] The collaborating UE may communicate with a network node (such as a satellite, a base station (BS) or a network apparatus in the mobile communications network) in a first frequency band f1 and communicate with the primary UE in a second frequency band f2. The collaborating UE may perform inter-band frequency translation to translate the radio frequency (RF) carrier of the received signal from the first frequency band f1 to the second frequency band f2 and vice versa. This device collaboration is applicable to both uplink and downlink transmissions.
[0038] Compared to smartphones, a wearable device typically has less capability in terms of MIMO processing capability, number of transmitting (Tx) or receiving (Rx) antennas, carrier aggregation (CA) capability, etc. The smartphone may act as an advanced amplify and forward (AF) repeater with better Rx beamforming capability (i.e., more receive antennas) , and may purify signal quality by rejecting interference coming from un-expected directions, and forward processed signal to the low-capability wearable device.
[0039] FIG. 3 illustrates an example scenario 300 of rank augmentation based on device collaboration in accordance with implementations of the present disclosure. One smartphone and one collaborating device (such as a relay device, another smartphone, an indoor CPE, or others) collaborate to receive, at the smartphone, a resulting high-rank data signal transmitted from the network node (such as a satellite, a base station or a network apparatus in the mobile communications network) .
[0040] In this device collaboration scenario, the smartphone may be a primary communication apparatus or a primary UE and the aforementioned collaborating device may be a collaborating communication apparatus or a collaborating UE. The primary UE may communicate with the network node in a first frequency band f1 and communicate with the collaborating UE in a second frequency band f2. The collaborating UE may communicate with the network node in the first frequency band f1, and communicate with the primary UE in the second frequency band f2. The collaborating UE may perform inter-band frequency translation to translate the RF carrier of the received signal from the first frequency band f1 to the second frequency band f2 and vice versa. This device collaboration is also applicable to both uplink and downlink transmissions.
[0041] A device-control path CTRL may be established between the primary UE and the collaborating UE to exchange control signaling or critical information, including CSI, repeater-mode enabling, power control etc. The primary UE may utilize its CA capability to receive signals directed from the base station and the collaborating UE simultaneously in two bands f1 and f2 and processes the received signals jointly, as if having two sets of Rx antennas. The network node may transmit / receive a signal in frequency band f1 to an end-device that appears to be equipped with two sets of Rx antennas, so the rank of the end-to-end MIMO channel rank may be doubled.
[0042] Note that FIG. 1, FIG. 2 and FIG. 3 are illustrative only and are not intended to be limitation of the applications in any way. For example, in some implementations, a primary apparatus (e.g., the aforementioned primary device, primary UE or primary communication apparatus) (hereinafter named as the primary apparatus for brevity) and a collaborating apparatus (e.g., the aforementioned collaborating device, collaborating UE or collaborating communication apparatus) (hereinafter named as the collaborating apparatus for brevity) may camp on or may be associated with (e.g., establishing a connection with) the same network node. That is, intra-radio access technology (RAT) services may be provided to the primary apparatus and the collaborating apparatus.
[0043] For another example, in some implementations, the primary apparatus and the collaborating apparatus may camp on or may be associated with different network nodes of the same RAT (e.g., intra-RAT) or of different RATs (e.g., inter-RAT) .
[0044] To reduce power consumption in the collaborating apparatus (as well as in the primary apparatus) capable of supporting device collaborative communications, several power-saving schemes are introduced with respect to different aspects and different scenarios.
[0045] In a first aspect of the present disclosure, power-saving schemes regarding the apparatuses supporting intra-RAT services of the same operator are introduced. In the first aspect of the present disclosure, the collaborating apparatus and the primary apparatus may camp on or may be associated with the same network node (e.g., the same base station or the same operator) .
[0046] In some implementations in the first aspect, the power-saving schemes may be introduced in two scenarios, comprising a first scenario of which the primary apparatus is in a connected mode (e.g., a radio resource control (RRC) connected mode) and a second scenario of which the primary apparatus is not in the connected mode (e.g., the primary apparatus is in an idle mode (such as an RRC idle mode) , or in an inactive mode (such as an RRC inactive mode)) .
[0047] In some implementations in the first aspect, in an event that the primary apparatus is in the connected mode (the first scenario) and the collaborating apparatus is in the connected mode, power-saving information may be provided to the collaborating apparatus by the network node, by the primary apparatus, or both.
[0048] In some implementations in the first aspect, in an event that the primary apparatus is in the connected mode (the first scenario) and the collaborating apparatus is in the inactive mode, power-saving information may be provided to the collaborating apparatus by the network node (e.g., via small data transmission) , by the primary apparatus, or both.
[0049] Alternatively, in some implementations in the first aspect, in an event that the primary apparatus is in the connected mode (the first scenario) and the collaborating apparatus is in the inactive mode, the device collaboration may be terminated.
[0050] In some implementations in the first aspect, in an event that the primary apparatus is in the connected mode (the first scenario) and the collaborating apparatus is in the idle mode, power-saving information may be provided to the collaborating apparatus by the primary apparatus.
[0051] Alternatively, in some implementations in the first aspect, in an event that the primary apparatus is in the connected mode (the first scenario) and the collaborating apparatus is in the idle mode, the device collaboration may be terminated.
[0052] In some implementations, the power-saving information may be provided to the collaborating apparatus, for the collaborating apparatus to be informed of when to relay or not to relay, and the energy usage may be thereby optimized.
[0053] In some implementations, the power-saving information may be associated with the primary apparatus and may comprise at least one of a discontinuous reception (DRX) configuration, a wake-up signal (WUS) indication, an activation of a configurated grant for a downlink (DL) reception or an uplink (UL) transmission (e.g., whether configured grant DL / UL is activated) , an occasion of the configurated grant for the downlink reception or the uplink transmission, physical downlink control channel (PDCCH) monitoring information (e.g., monitoring periodicity, skipping duration, etc. ) , search space set information, search space group information, whether the primary apparatus is in sleeping state, bandwidth part (BWP) information (e.g., frequency bandwidth and location) , whether data relay is necessary for a time duration (e.g., a dynamic indication) , a data relaying pattern (e.g., semi-static indication) , and transmission occasion or periodicity of a reference signal (e.g., a channel state information reference signal (CSI-RS) , a sounding reference signal (SRS) or a tracking reference signal (TRS)) .
[0054] Additionally, in some implementations in the first aspect, in an event that the primary apparatus is in the connected mode (the first scenario) , the collaborating apparatus may have or may be informed of the information regarding the PDCCH monitoring occasion and / or the cell Radio Network Temporary Identifier (C-RNTI) of the primary apparatus, and may help to monitor the PDCCH for the primary apparatus.
[0055] In some implementations, the collaborating apparatus may determine when to or not to relay data based on the received power-saving information. In some implementations, if the power-saving information is provided by the network node, the power-saving information may be provided by L1 (layer 1) signaling (e.g., downlink control information (DCI) (e.g., new DCI format or new DCI fields in scheduling DCI) or media access control (MAC) control element (MAC-CE) ) or higher layer signaling (e.g., UE-specific RRC signaling) .
[0056] In some implementations, additional information (e.g., the additional power-saving information) associated with the collaborating apparatus may be provided to the primary apparatus by the network node, by the collaborating apparatus, or both.
[0057] In some implementations, the additional information may comprise a DRX configuration, a WUS indication, an activation of a configurated grant for a downlink reception or a uplink transmission (e.g., whether configured grant DL / UL is activated) , an occasion of the configurated grant for the downlink reception or the uplink transmission, PDCCH monitoring information (e.g., monitoring periodicity, skipping duration, etc. ) , search space set information, search space group information, whether the collaborating apparatus is in sleeping state, whether data relay is necessary for a time duration (e.g., a dynamic indication) and a data relaying pattern (e.g., semi-static indication) .
[0058] In some implementations, the primary apparatus may determine when to have data relaying based on the additional information. For example, the primary apparatus may determine that data relaying occurs if the collaborating apparatus is in active state or if data relaying pattern indicates that ‘having data relaying’ . In some implementations, the network node may provide the additional information by L1 signaling (e.g., DCI (new DCI format or new DCI fields in scheduling DCI) or MAC-CE) or higher layer signaling (e.g., UE-specific RRC signaling) .
[0059] In some implementations, in an event that the additional information is not provided, the primary apparatus may assume that there is always data relaying when it is not in the sleep state. In some implementations, if the collaborating apparatus doesn’ t relay data for the primary apparatus, the network node may know this either reported by the collaborating apparatus or the primary apparatus.
[0060] FIG. 4 illustrates an example scenario under schemes in accordance with implementations of the present disclosure. Scenario 400 illustrates an example of using the power-saving information to align an active state or a sleep state of the primary apparatus and the collaborating apparatus. Scenario 400 sequentially depicts the DRX configuration of the collaborating apparatus (the original configuration) , the DRX configuration of the primary apparatus and the resulting DRX configuration with extended DRX active period of the collaborating apparatus obtained by aligning the active states of the primary apparatus and the collaborating apparatus.
[0061] In some implementations, in an event that the device collaboration or the pairing between the primary apparatus and the collaborating apparatus is known by the network node (i.e., not transparent to the network node) , the network node may align the DRX configuration for the primary apparatus and the collaborating apparatus via RRC (re) -configuration. In some implementations, an L1 signaling to indicate the collaborating apparatus to extend the DRX active time or period (which may be regarded as a virtual DRX on) may be transmitted by the network node. During the extended DRX active period, collaborating apparatus may not expect to monitor its DL control channel.
[0062] In some implementations, an L1 signaling to indicate ‘no data relaying’ to the collaborating apparatus may be transmitted by the network node. During the time or period indicated as no data relaying’ , collaborating apparatus may not expect to monitor its DL control channel.
[0063] In some implementations, in an event that the device collaboration or the pairing between the primary apparatus and the collaborating apparatus is not known by the network node (i.e., transparent to the network node) , the DRX information may be exchanged between the primary apparatus and the collaborating apparatus. In some implementations, the primary apparatus and the collaborating apparatus may negotiate about a preferred DRX configuration and report the preferred DRX configuration to the network node (e.g., via UE assistance information (UAI)) .
[0064] In some implementations, dynamic adaptation (e.g., wake-up indication and / or dynamic PDCCH adaptation information) regarding the primary apparatus may also be provided to the collaborating apparatus for power saving.
[0065] With respect to the termination of the device collaboration in the first aspect, a termination indication may be provided to the primary apparatus by one or a set of different approaches. In some implementations, the collaborating apparatus may provide a collaboration terminate indication to the primary apparatus via control signaling between primary apparatus and collaborating apparatus. In some implementations, the collaborating apparatus may stop transmitting an alive reference signal to the primary apparatus. The alive reference signal may be used to measure the signal quality between collaborating apparatus and the primary apparatus.
[0066] In some implementations, in an event that the device collaboration or the pairing between the primary apparatus and the collaborating apparatus is known by the network node, the network node may provide the collaboration terminate indication to the primary apparatus implicitly (e.g., via rank adaptation) or explicitly, where the explicit signaling may be carried out via L1 signaling or higher layer signaling (e.g., UE-specific RRC signaling) .
[0067] In some implementations in the first aspect, in an event that the primary apparatus is not in the connected mode (the seconds scenario) , the device collaboration may be terminated. In some implementations, the primary apparatus may provide the collaboration terminate indication to the collaborating apparatus via control signaling between primary apparatus and collaborating apparatus.
[0068] In some implementations, in an event that the device collaboration or the pairing between the primary apparatus and the collaborating apparatus is known by the network node (i.e., not transparent to the network node) , the network node may provide the collaboration terminate indication to the collaborating apparatus implicitly (e.g., via rank adaptation) or explicitly, where the explicit signaling may be carried out via L1 signaling or higher layer signaling (e.g., UE-specific RRC signaling) .
[0069] In some implementations in the first aspect, in an event that the primary apparatus is not in the connected mode (the seconds scenario) , the collaborating apparatus may not do data relaying, but may still help to monitor the paging message for the primary apparatus and wake up the primary apparatus if needed via control signaling between the primary apparatus and the collaborating apparatus. In some implementations, the collaborating apparatus may be configured with paging occasion and / or an identity of the primary apparatus, and the primary apparatus may determine not to monitor its paging channel in the paging occasion.
[0070] In some implementations, the collaborating apparatus may comprise not only a main transceiver but also a low-power transceiver. The low-power transceiver may be a dedicated transceiver for data relaying and / or for some predetermined operations. When the main transceiver is active, either the main transceiver or the low-power transceiver may be used for data relaying and / or monitoring the paging message. When the main transceiver is sleeping, the low-power transceiver may be used for data relaying and / or monitoring the paging message.
[0071] In some implementations, the low-power transceiver may be turned on or turned off based on the power-saving information. In some implementations, the low- power transceiver may also be used for control singling exchange between the primary apparatus and the collaborating apparatus.
[0072] In a second aspect of the present disclosure, power-saving schemes regarding the apparatuses not supporting intra-RAT services of the same operator are introduced. In the second aspect of the present disclosure, the collaborating apparatus and the primary apparatus may camp on or may be associated with the different network nodes of the same RAT, or may camp on or may be associated with the network nodes of different RATs (i.e., the inter-RAT techniques) .
[0073] In some implementations in the second aspect, the power-saving schemes may be introduced in two scenarios, comprising a first scenario of which the primary apparatus is in a connected mode (e.g., an RRC connected mode) and a second scenario of which the primary apparatus is not in the connected mode (e.g., the primary apparatus is in an idle mode (such as an RRC idle mode) , or in an inactive mode (such as an RRC inactive mode)) .
[0074] In some implementations in the second aspect, in an event that the primary apparatus is in the connected mode (the first scenario) , power-saving information may be provided to the collaborating apparatus by the primary apparatus via control signaling between the primary apparatus and the collaborating apparatus.
[0075] In some implementations, the power-saving information may be provided to the collaborating apparatus, for the collaborating apparatus to be informed of when to relay or not to relay, and the energy usage may be thereby optimized.
[0076] In some implementations, the control signaling may be transmitted based on the techniques on unlicensed band, e.g., Wi-Fi, Bluetooth, LoRa (Long Range) , Sigfox, or others. In some implementations, the control signaling may be transmitted based on the techniques on licensed band, e.g., NB-IoT, or others.
[0077] In some implementations, the power-saving information may be associated with the primary apparatus and may comprise at least one of a DRX configuration, a wake-up signal indication, an activation of a configurated grant for a downlink reception or an uplink transmission (e.g., whether configured grant DL / UL is activated) , an occasion of the configurated grant for the downlink reception or the uplink transmission, PDCCH monitoring information (e.g., monitoring periodicity, skipping duration, etc. ) , search space set information, search space group information, whether the primary apparatus is in sleeping state, BWP information (e.g., frequency bandwidth and location) , transmission occasion or periodicity of a reference signal (e.g., a CSI-RS, an SRS or a TRS) , whether data relay is necessary for a time duration (e.g., a dynamic indication) , a data relaying pattern (e.g., semi-static indication) , and a collaboration terminate indication (if the device collaboration is determined to be terminated) .
[0078] In some implementations, information regarding dynamic adaptation (such as a wake-up indication, dynamic PDCCH adaptation information, etc. ) regarding the primary apparatus may be also provided to the collaborating apparatus as the power-saving information for power saving. In some implementations, the collaborating apparatus may determine when to relay data based on the received power-saving information.
[0079] In some implementations, additional information (e.g., the additional power-saving information) associated with the collaborating apparatus may be provided to the primary apparatus by the collaborating apparatus via control signaling between the primary apparatus and the collaborating apparatus.
[0080] In some implementations, the additional information may comprise a DRX configuration, a duty cycle configuration, whether the collaborating apparatus is in sleeping state, whether there is data relaying during a time duration (e.g., a dynamic indication) , a data relaying pattern (e.g., semi-static indication) and a collaboration terminate indication (explicit or implicit signaling if the device collaboration is determined to be terminated) .
[0081] In some implementations, the primary apparatus may determine when to have data relaying based on the additional information. For example, the primary apparatus may determine that data relaying occurs if the collaborating apparatus is in active state or if data relaying pattern indicates that ‘having data relaying’ .
[0082] In some implementations, in an event that the additional information is not provided, the primary apparatus may assume that there is always data relaying when it is not in the sleep state. In some implementations, if the collaborating apparatus doesn’ t relay data for the primary apparatus, the network node may know this from the reporting of the primary apparatus. For example, the network node may assume no rank augmentation if the data relaying is in an off period (e.g., a relay-off duration) .
[0083] FIG. 5 illustrates an example scenario under schemes in accordance with implementations of the present disclosure. Scenario 500 illustrates an example of using the power-saving information to align an active state or a sleep state of the primary apparatus and the collaborating apparatus.
[0084] In some implementations, information may be exchanged between the primary apparatus and the collaborating apparatus. For example, the primary apparatus and the collaborating apparatus may negotiate about a preferred DRX configuration. The primary apparatus may report the negotiation result (e.g., the preferred DRX configuration) to the network node (e.g., via UAI) and the collaborating apparatus may report the negotiation result to its service provider (e.g., a Wi-Fi access point (AP)) .
[0085] For another example, the primary apparatus and the collaborating apparatus may negotiate about a data relaying pattern and the data relaying is performed by the collaborating apparatus based on the data relaying pattern. The data relaying pattern may be known by the network node from the reporting of the primary apparatus.
[0086] In the data relaying on / active period, the collaborating apparatus may relay data of the primary apparatus. The primary apparatus may expect to receive the data relayed from the collaborating apparatus either for rank augmentation or diversity augmentation. In the data relaying off / inactive period, the collaborating apparatus does not relay data of the primary apparatus. Therefore, the primary apparatus may not expect to receive the data relayed from the collaborating apparatus.
[0087] In some implementations in the second aspect, in an event that the primary apparatus is not in the connected mode (the seconds scenario) , the device collaboration may be terminated. In some implementations, the primary apparatus may provide the collaboration terminate indication to the collaborating apparatus via control signaling between primary apparatus and collaborating apparatus.
[0088] In some implementations in the second aspect, in an event that the primary apparatus is not in the connected mode (the seconds scenario) , the collaborating apparatus may not do data relaying, but may still help to monitor the paging message for the primary apparatus and wake up the primary apparatus if needed via control signaling between the primary apparatus and the collaborating apparatus. In some implementations, the collaborating apparatus may be configured with paging occasion and / or an identity of the primary apparatus, and the primary apparatus may determine not to monitor its paging channel in the paging occasion. In some implementations, the collaborating apparatus may be capable of monitoring the paging channel (s) and / or decoding the paging message (s) of the primary apparatus.
[0089] In some implementations, the collaborating apparatus may comprise not only a main transceiver but also a low-power transceiver. The low-power transceiver may be a dedicated transceiver for data relaying and / or for some predetermined operations. When the main transceiver is active, either the main transceiver or the low-power transceiver may be used for data relaying and / or monitoring the paging message. When the main transceiver is sleeping, the low-power transceiver may be used for data relaying and / or monitoring the paging message.
[0090] In some implementations, the low-power transceiver may be turned on or turned off based on the power-saving information. In some implementations, the low-power transceiver may also be used for control singling exchange between the primary apparatus and the collaborating apparatus.
[0091] With respect to the operations of the collaborating apparatus for power saving in device collaborative communications, in either the first aspect and second aspect of the present disclosure, the collaborating apparatus may receive first power-saving information associated with the primary apparatus of device collaboration from at least one of the network node and the primary apparatus and may determine a relay-on duration for which a signal relaying is performed and a relay-off duration for which the signal relaying is not performed based on the first power-saving information. In some implementations, the collaborating apparatus may relay a signal between the primary apparatus and the network node in the relay-on duration (e.g., in the extended DRX active period as depicted in FIG. 4 and / or in the data relaying on / active period as depicted in FIG. 5) .
[0092] In some implementations, the first power-saving information may comprise at least one of a DRX configuration, a WUS indication, an activation of a configurated grant for a downlink reception or an uplink transmission, an occasion of the configurated grant for the downlink reception or the uplink transmission, PDCCH monitoring information, search space set information, search space group information, BWP information, a data relaying pattern, a reference signal transmission occasion or periodicity, a dynamic adaptation of the primary apparatus for power saving, a state of the primary apparatus and a collaboration terminate indication.

[0237] 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.

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.
