Abstract
Description
METHODS AND APPARATUS FOR USER EQUIPMENT ACTIVE TIME ADAPTATION IN MOBILE COMMUNICATIONSCROSS REFERENCE TO RELATED PATENT APPLICATION (S)
[0001] The present disclosure is part of a non-provisional application claiming the priority benefit of U.S. Patent Application No. 63 / 635,667, filed 18 April 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 user equipment (UE) active time adaptation with respect to apparatus and network node in mobile communications.BACKGROUND
[0003] Unless otherwise indicated herein, approaches described in this section are not prior art to the claims listed below and are not admitted as prior art by inclusion in this section.
[0004] Wireless communication systems may be widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may use multiple-access technologies capable of supporting communication with multiple users by sharing available system resources. Examples of such multiple-access technologies may include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single-carrier frequency division multiple access (SC-FDMA) systems, and time division synchronous code division multiple access (TD-SCDMA) systems.
[0005] These multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different wireless devices to communicate on a municipal, national, regional, and even global level. An example telecommunication standard is 5G New Radio (NR) . 5G NR is part of a continuous mobile broadband evolution promulgated by Third Generation Partnership Project (3GPP) to meet new requirements associated with latency, reliability, security, scalability (e.g., with Internet of Things (IoT) ) , and other requirements. Some aspects of 5G NR may be based on the 4G long term evolution (LTE) standard. There exists a need for further improvements in 5G NR technology. These improvements may also be applicable to other multi-access technologies and the telecommunication standards that employ these technologies.
[0006] In conventional communication technologies, the user equipment (UE) discontinuous reception (DRX) may create multiple active windows for different traffic types. That is, each UE may have different DRX settings or DRX offsets for different traffic types. Therefore, the network node needs to frequently wake up to serve multiple UEs with different DRX settings or DRX offsets. As a result, the energy consumption for the network node and UEs may increase because of the complex DRX settings or DRX offsets.
[0007] Accordingly, how to avoid the frequent wake-up for the UE and network node for energy saving and how to increase the energy efficiency in the wireless communication environments becomes an important issue for the newly developed wireless communication network. Therefore, there is a need to provide proper schemes for cell-wise UE active time adaptation to achieve energy saving.SUMMARY
[0008] The following summary is illustrative only and is not intended to be limiting in any way. That is, the following summary is provided to introduce concepts, highlights, benefits and advantages of the novel and non-obvious techniques described herein. Select implementations are further described below in the detailed description. Thus, the following summary is not intended to identify essential features of the claimed subject matter, nor is it intended for use in determining the scope of the claimed subject matter.
[0009] One objective of the present disclosure is to propose schemes, concepts, designs, systems, methods and apparatus pertaining to user equipment (UE) active time adaptation with respect to apparatus and network node in mobile communications. It is believed that the above-described issue would be avoided or otherwise alleviated by implementing one or more of the proposed schemes described herein.
[0010] In one aspect, a method may involve a network node determining a group of UEs. The method may also involve the network node determining a configuration for an active window associated with the group of UEs. The active window may comprise a plurality of sub-windows respectively corresponding to each UE of the group of UEs. The method may further involve the network node transmitting the configuration to the group of UEs to indicate an active time of each UE of the group of UEs.
[0011] In another aspect, a method may involve an apparatus receiving a configuration for an active window associated with a group of UEs from a network node. The active window may comprise a plurality of sub-windows respectively corresponding to each UE of the group of UEs. The method may also involve the apparatus determining an active time of the apparatus in the active window according to the configuration.
[0012] It is noteworthy that, although description provided herein may be in the context of certain radio access technologies, networks and network topologies such as 5th Generation System (5GS) and 4G EPS mobile networking, the proposed concepts, schemes and any variation (s) / derivative (s) thereof may be implemented in, for and by other types of wireless and wired communication technologies, networks and network topologies such as, for example and without limitation, Ethernet, Universal Terrestrial Radio Access Network (UTRAN) , E-UTRAN, Global System for Mobile communications (GSM) , General Packet Radio Service (GPRS) / Enhanced Data rates for Global Evolution (EDGE) Radio Access Network (GERAN) , Long-Term Evolution (LTE) , LTE-Advanced, LTE-Advanced Pro, IoT, Industrial IoT (IIoT) , Narrow Band Internet of Things (NB-IoT) , 6th Generation (6G) , and any future-developed networking technologies.

[0024] 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
[0025] Implementations in accordance with the present disclosure relate to various techniques, methods, schemes and / or solutions pertaining to user equipment (UE) active time adaptation with respect to UE and network apparatus 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.
[0026] FIG. 1 illustrates an example scenario 100 of a communication environment in which various solutions and schemes in accordance with the present disclosure may be implemented. Scenario 100 involves a UE 110 in wireless communication with a network 120 (e.g., a wireless network including an NTN and a TN) via a terrestrial network node 125 (e.g., an evolved Node-B (eNB) , a Next Generation Node-B (gNB) , or a transmission / reception point (TRP) ) and / or a non-terrestrial network node 128 (e.g., a satellite) . For example, the terrestrial network node 125 and / or the non-terrestrial network node 128 may form a non-terrestrial network (NTN) serving cell for wireless communication with the UE 110. In some implementations, the UE 110 may be an IoT device such as an NB-IoT UE or an enhanced machine-type communication (eMTC) UE (e.g., a bandwidth reduced low complexity (BL) UE or a coverage enhancement (CE) UE) . In such communication environment, the UE 110, the network 120, the terrestrial network node 125, and the non-terrestrial network node 128 may implement various schemes pertaining to improved UE active time adaptation procedure in accordance with the present disclosure, as described below. 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.
[0027] According to the implementations of the present disclosure, a network node (e.g., the terrestrial network node 125 or the non-terrestrial network node 128) may determine a group of user equipments (UEs) . In an example, the network node may determine the group of UEs based on UE capability information or UE traffic type information (e.g., traffic service type) of one or more UEs. In addition, the network node may determine a configuration for an active window associated with the group of UEs. The active window may comprise a plurality of sub-windows (e.g., sub-window #1, sub-window #2, sub-window #3 and sub-window #4 shown in FIG. 2) respectively corresponding to each UE of the group of UEs. The network node may transmit the configuration to the group of UEs to indicate an active time of each UE of the group of UEs. In an example, the network node may transmit the configuration through a higher layer signaling (e.g., radio resource control (RRC) signaling) . In an event that a UE (e.g., UE 110) receives the configuration from the network node, the UE may determine an active time of the UE in the active window according to the configuration. Therefore, according to the implementations of the present disclosure, a unified active window between the network nodes and UEs may achieve energy saving and increase the energy efficiency for the network node and UEs.
[0028] In some implementations, the configuration may comprise at least one of a sector offset, a cycle length, an on duration (i.e., the duration of the active window) , the number of groups, a sub-window length, an inactivity timer, and a retransmission timer. In addition, the configuration may further comprise a pattern associated with the active window and a periodicity of each sub-window in the cycle length. The active time corresponding to the active window may comprise at least one of the on duration, the time while the inactivity timer is running, and the time while the retransmission timer is running.
[0029] The sector offset may be used to define where the active window starts. The cycle length may be used to define the periodicity of the active window. In an example, the cycle length may be indicated through the radio resource control (RRC) signaling. In another example, the cycle length may be calculated by the UE according to an offset. The cycle length may be set to different values for different traffic service types, e.g., 40 milliseconds (ms) for voice over internet protocol (VoIP) service, and 160 ms for file transfer protocol (FTP) service. The on duration may be used to indicate a duration at a beginning of the active window. In an implementation, for the mixed traffic service, the network node may configure the active window with a short cycle length to the UE and notify the UE to adapt the sub-window (or sub-group) periodicity through a downlink control information (DCI) .
[0030] The number of groups may be used to indicate the number of groups in the active window. The UEs may be divided into different groups in the active window. The sub-window length may be used to indicate of the length of each group (or each sub-window) in the active window. The sub-window length of each group (or each sub-window) in the active window may be the same or different. For example, if the pattern associated with the groups (or sub-windows) in the active window is [1, 1, 2, 5] , it means that there are 4 groups in the active window, and the sub-window length of the first group is 1, the sub-window length of the second group is 1, the sub-window length of the third group is 2, and the sub-window length of the fourth group is 5. In an example, the sub-window length may be indicated through the RRC. In another example, in an event that the length of each group in the active window is the same, the sub-window length may be calculated by the UE according to the on duration and the number of groups in the active window.
[0031] FIG. 2 illustrates an example scenario 200 for an active window in accordance with implementations of the present disclosure. Scenario 200 involves a UE and a network node (e.g., a (macro / micro) base station) of a serving cell which may be a part of a wireless network (e.g., an LTE network, a 5G / NR network, an IoT network or a 6G network. Referring to FIG. 2, the active window may comprise four sub-windows, e.g., sub-window #1, sub-window #2, sub-window #3 and sub-window #4. The sub-window length of each sub-window in the active window may be the same or different. The active window may start after the sector offset. The active window may correspond to a cycle length.
[0032] The inactivity timer may be used to indicate the duration after the physical downlink control channel (PDCCH) occasion in which a PDCCH may indicate a new uplink (UL) or downlink (DL) transmission for the medium access control (MAC) entity. The retransmission timer may be used to indicate the maximum duration until a DL retransmission or a grant for an UL retransmission is received. The data scheduling (e.g., new UL or DL transmission or DL retransmission) may trigger the inactivity timer or retransmission timer to extend the length of the sub-window.
[0033] In some implementations, the pattern associated with the active window (on duration) may comprise a bit-map which may be used to indicate the on durations. The periodicity of each sub-window in the cycle length may be updated through a layer 1 (L1) indication.
[0034] FIG. 3 illustrates an example scenario 300 for patterns associated with the active window (or on duration) in accordance with implementations of the present disclosure. Scenario 300 involves a UE and a network node (e.g., a (macro / micro) base station) of a serving cell which may be a part of a wireless network (e.g., an LTE network, a 5G / NR network, an IoT network or a 6G network. Referring to FIG. 3, the cycle length is 160 ms, and the length of the active window (or on duration) is 40 ms. In the cycle length, four active windows (or on durations) can be activated. Each active window may comprise four sub-windows (or four groups) , and the length of each sub-window is 10 ms, e.g., [10, 10, 10, 10] . Each sub-window (or group) may correspond to different traffic service types. In addition, each sub-window (or group) may correspond to different periodicities according to its corresponding traffic service type, e.g., UE traffic type 1, UE traffic type 2, UE traffic type 3 and UE traffic type 4.
[0035] In an example, referring to FIG. 3, in an event that the traffic load is low in the cycle length, the pattern associated with the active window (or on duration) in the cycle length may be [1, 0, 0, 0] . That is, in the cycle length, only one active window (or on duration) needs to be activated, i.e., the UEs corresponding to different sub-windows may only be activated in one active window (or on duration) in the cycle length to save energy. In addition, in the example, in the cycle length, the periodicity of each sub-window respectively corresponding to the UE traffic type 1, the UE traffic type 2, UE traffic type 3 and UE traffic type 4 may be 0.
[0036] In another example, referring to FIG. 3, in an event that the traffic load is high in the cycle length, the pattern associated with the active window (or on duration) in the cycle length may be [1, 1, 1, 1] . That is, in the cycle length, all active windows (or on durations) need to be activated. In addition, in the example, in the cycle length, the sub-windows respectively corresponding to the UE traffic type 1, the UE traffic type 2, UE traffic type 3 and UE traffic type 4 may correspond to different periodicities. That is, the UE may be activated according to its UE traffic type in the cycle length. For example, the periodicity of the sub-window corresponding to UE traffic type 1 (e.g., extended reality (XR) UE) may be 1, i.e., the UE divided into the group corresponding to the UE traffic type 1 may be activated every one sub-window in the cycle length. In another example, the periodicity of the sub-window corresponding to UE traffic type 2 (e.g., Voice over Internet Protocol (VoIP) ) may be 4, i.e., the UE divided into the group corresponding to the UE traffic type 2 may be activated every four sub-windows in the cycle length. In another example, the periodicity of the sub-window corresponding to UE traffic type 3 (e.g., File Transfer Protocol (FTP) UE) may be 8, i.e., the UE divided into the group corresponding to the UE traffic type 3 may be activated every eight sub-windows in the cycle length. In another example, the periodicity of the sub-window corresponding to UE traffic type 4 (e.g., FTP UE or Instant Messenger (IM) UE) may be 16, i.e., the UE divided into the group corresponding to the UE traffic type 4 may be activated every sixteen sub-windows in the cycle length.
[0037] In some implementations, the network node may determine a start point of an offset for each sub-window according to a start point of a sector offset or a start point of the active window.
[0038] In some implementations, the network node may determine a length of each sub-window according to a UE capability information or a UE traffic type information. The network node may indicate the length of each sub-window through RRC parameters.
[0039] In some implementations, the UE may determine (or calculate) a length (or length offset) of the sub-window of the UE according to a UE identification (ID) , a beam direction or a transmission configuration indicator (TCI) index state. Specifically, in an example, the UE may determine the group (or sub-window) associated with the UE according to the UE ID to obtain the length (or length offset) of the sub-window of the UE. In another example, the UE may determine the synchronization signal block (SSB) index to obtain the beam direction, and then determine the group (or sub-window) associated with the UE according to the beam direction, e.g., beam 1 may be associated with group 1 and beam 2 may be associated with group 2, to obtain the length (or length offset) of the sub-window of the UE. In another example, the UE may determine the TCI index state associated with an SSB index, and then determine the group (or sub-window) associated with the UE according to the SSB index to obtain the length (or length offset) of the sub-window of the UE.
[0040] According to the implementations of the present disclosure, the network node may transmit a common signal configuration to the group of UEs. The common signal configuration may comprise a wake-up signal (WUS) configuration and a pre-configured adaptation. In an example, the common signal configuration may be transmitted through a DCI.
[0041] The WUS configuration may indicate the UE whether to wake up or not in the following sub-window. In an example, the UE may determine whether to wake up to monitor the DL control channel in the following sub-window according to the WUS configuration. In another example, if the network node does not configure the WUS configuration, the UE may determine whether to wake up to monitor the DL control channel in the following sub-window according to a default operation.
[0042] The pre-configured adaptation may be applied for the energy saving of the network node and / or the UE. The pre-configured adaptation may comprise at least one of a time domain adaptation (e.g., update the parameters in the active window) , a spatial domain adaptation, a carrier domain adaptation, a power domain adaptation, and a frequency domain adaptation.
[0043] According to the implementations of the present disclosure, the UE may have a low power receiver (LR) and a main receiver (MR) , e.g., the transceiver 816 of the communication apparatus 810 may comprise an LR and an MR. In an example, the WUS configuration may be received by the LR of the UE, and the pre-configured adaptation may be received by the MR of the UE. In another example, the WUS configuration and the pre-configured adaptation may be received by the MR of the UE.
[0044] In some implementations, a position of transmitting the common signal configuration may be outside the active window (e.g., the common signal shown in FIG. 4) or within each sub-window (e.g., the common signal shown in FIG. 5) . In an example, the UE may determine a position of the common signal configuration according to the active window (e.g., option 1 shown in FIG. 4 and FIG. 5) , a sub-window associated with the apparatus (e.g., option 2 shown in FIG. 4 and FIG. 5) , a synchronization signal block (SSB) burst (e.g., option 3 shown in FIG. 4) or a configured offset. In another example, the UE may determine the position of the active window according to the common signal configuration or a configured offset (e.g., FIG. 6) .
[0045] FIG. 4 illustrates an example scenario 400 for a position of the common signal configuration in accordance with implementations of the present disclosure. Scenario 400 involves a UE and a network node (e.g., a (macro / micro) base station) of a serving cell which may be a part of a wireless network (e.g., an LTE network, a 5G / NR network, an IoT network or a 6G network. Referring to FIG. 4, the position of transmitting the common signal configuration may be outside the active window. In an example, the UE may determine the position of the common signal configuration according to a start point of an active window (e.g., option 1) . In another example, the UE may determine the position of the common signal configuration according to a start point of sub-window associated with the UE (e.g., option 2) . In another example, the UE may determine the position of the common signal configuration according to a position of an SSB burst (e.g., option 3) . In another example, the UE may determine the position of the common signal configuration according to a configured offset.
[0046] FIG. 5 illustrates another example scenario 500 for a position of the common signal configuration in accordance with implementations of the present disclosure. Scenario 500 involves a UE and a network node (e.g., a (macro / micro) base station) of a serving cell which may be a part of a wireless network (e.g., an LTE network, a 5G / NR network, an IoT network or a 6G network. Referring to FIG. 5, the position of transmitting the common signal configuration may be within each sub-window. In an example, the UE may determine the position of the common signal configuration according to a start point of an active window (e.g., option 1) . In another example, the UE may determine the position of the common signal configuration according to a start point of sub-window associated with the UE (e.g., option 2) .
[0047] FIG. 6 illustrates an example scenario 600 for determining a position of the active window configuration in accordance with implementations of the present disclosure. Scenario 600 involves a UE and a network node (e.g., a (macro / micro) base station) of a serving cell which may be a part of a wireless network (e.g., an LTE network, a 5G / NR network, an IoT network or a 6G network. Referring to FIG. 6, the UE may determine the position (or start point) of the active window according to the position of the common signal configuration.
[0048] In some implementations, the WUS configuration may comprise at least one of a validity time of WUS, an application delay and the number of bits for WUS.
[0049] In an example, in an event that the position of transmitting the common signal configuration is outside the active window, the validity time of WUS may be the timing of waking up the UE for the operations associated with the current active window, or for updating the configuration for the current active window (e.g., group 1 shown in FIG. 7) . In another example, in an event that the position of transmitting the common signal configuration is within each sub-window, the validity time of WUS may be the timing of waking up the UE for the operations associated with the current sub-window (e.g., group 2 shown in FIG. 7) .
[0050] FIG. 7 illustrates an example scenario 700 for a validity time of WUS in accordance with implementations of the present disclosure. Scenario 700 involves a UE and a network node (e.g., a (macro / micro) base station) of a serving cell which may be a part of a wireless network (e.g., an LTE network, a 5G / NR network, an IoT network or a 6G network. Referring to FIG. 7, in group 1, in an event that the position of transmitting the common signal configuration is outside the active window, the validity time of WUS may be the timing of waking up the UE for the operations associated with the current active window, or for updating the configuration for the current active window. In group 2, in an event that the position of transmitting the common signal configuration is within each sub-window, the validity time of WUS may be the timing of waking up the UE for the operations associated with the current sub-window.
[0051] In an example, the application delay may be X (e.g., an integer) times of a pattern (e.g., discontinuous reception (DRX) ) for different traffic. In another example, if the update information includes bandwidth (BW) switching, the application delay may be a BW switch delay. In another example, the application delay may be determined according to the UE capability (e.g., UE can report the time from receiving the signal to monitor PDCCH) . In another example, the UE may not expect to receive data or monitor PDCCH during the application delay.
[0052] The number of bits for the WUS may be determined according to the number of the sub-windows (or groups) in the active window, the UE-specific configuration (e.g., configuring one UE per group) or the number of the UEs. Illustrative Implementations

Communication apparatus 810 may further include one or more other components not pertinent to the proposed schemes of the present disclosure (e.g., internal power supply, display device and / or user interface device) , and, thus, such component (s) of communication apparatus 810 are neither shown in FIG. 8 nor described below in the interest of simplicity and brevity.
[0055] Network apparatus 820 may be a part of an electronic apparatus, which may be a network node such as a satellite, a BS, a small cell, a router or a gateway of an IoT network. For instance, network apparatus 820 may be implemented in a satellite or an eNB / gNB / TRP in a 4G / 5G / B5G / 6G, NR, IoT, NB-IoT or IIoT network. Alternatively, network apparatus 820 may be implemented in the form of one or more IC chips such as, for example and without limitation, one or more single-core processors, one or more multi-core processors, or one or more RISC or CISC processors.

Network apparatus 820 may further include one or more other components not pertinent to the proposed scheme of the present disclosure (e.g., internal power supply, display device and / or user interface device) , and, thus, such component (s) of network apparatus 820 are neither shown in FIG. 8 nor described below in the interest of simplicity and brevity.
[0056] In one aspect, each of processor 812 and processor 822 may be implemented in the form of one or more single-core processors, one or more multi-core processors, or one or more CISC processors.

[0085] 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.
[0086] 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.
[0087] 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.
