Description
METHODS AND APPARATUS FOR DETERMINING MEASUREMENT GAP REQUIREMENTS 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. Application No. 63 / 749,014, filed 24 January 2025, the content of which herein being incorporated by reference in its entirety.TECHNICAL FIELD
[0002] The present disclosure is generally related to wireless communications and, more particularly, to a method and apparatus for determining measurement gap requirements 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] In cellular communication systems, a user equipment (UE) is required to perform measurements on reference signals of serving and neighboring cells to support mobility. To perform inter-frequency measurements, the UE may require a "measurement gap" to tune its radio frequency (RF) chain to the target frequency. The network configures the UE with measurement objects (MOs) , and the UE reports whether a gap is needed for each target band.
[0005] A critical challenge in such systems is self-interference. When a UE transmits on an uplink band, non-linear characteristics of the RF components may generate harmonics that fall into downlink target bands designated for measurement.
[0006] An example is shown in FIG. 1, which illustrates a spectral distribution of such self-interference. As shown in FIG. 1, a UE operates on a source band (e.g., Band n3 NR) with a fundamental uplink frequency of fx. Due to RF non-linearity, this transmission generates harmonic products at integer multiples of the fundamental frequency, such as the second harmonic (2×fx) and the third harmonic (3×fx) .
[0007] In the example illustrated in FIG. 1, the second harmonic (2×fx) falls within Band n77 NR. The third harmonic (3×fx) falls within the frequency range of Band n46 NR (depicted as the gray block) .
[0008] Current 3GPP standards utilize a coarse reporting mechanism based on the target band. When the harmonic product (e.g., 3×fx) overlaps with the target band (Band n46) , generally, the UE is typically required to report a "need for gap" (gap-assisted measurement) .
[0009] However, a problem arises when considering the precise location of the reference signal. As shown in FIG. 1, the target band (Band n46) contains a specific reference signal, such as a synchronization signal block (SSB) of Band n46 NR (depicted as the black vertical bar) . In a problematic scenario (conceptually represented by the spectral arrangement in FIG. 1) , the harmonic (3×fx) might fall within the wide Target Band n46 but may not necessarily overlap with the specific bandwidth of the SSB.
[0010] When the SSB is located at a frequency offset from 3×fx (i.e., the harmonic hits the band but misses the SSB) , the interference does not actually degrade the measurement of the SSB. Despite this lack of actual interference on the SSB, existing UEs are configured to report a "gap" requirement solely because the harmonic falls within the Target Band limits.
[0011] This "per-band" reporting leads to the configuration of unnecessary measurement gaps, causing avoidable interruptions in data transmission and reducing spectral efficiency. Therefore, there is a need for a solution that determines gap requirements by considering the specific frequency relationship between the RF harmonics and the center frequency of the reference signals (e.g., SSBs) indicated in the MO.SUMMARY
[0012] 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.
[0013] An objective of the present disclosure is to propose solutions or schemes that address the aforementioned issue pertaining to determining measurement gap requirements in mobile communications.
[0014] In one aspect, a method may involve an apparatus receiving a measurement object (MO) from a network node. The method may also involve the apparatus transmitting a per MO indication to the network node for a measurement configured in the MO. The per MO indication indicates whether the apparatus requires a gap or an interruption to perform the measurement.
[0015] In another aspect, an apparatus may comprise a transceiver which, during operation, wirelessly communicates with a network node. The apparatus may also comprise a processor communicatively coupled to the transceiver. The processor, during operation, may perform operations comprising receiving, via the transceiver, a measurement object (MO) from the network node. The processor, during operation, may also perform operations comprising transmitting, via the transceiver, a per MO indication to the network node for a measurement configured in the MO. The per MO indication indicates whether the apparatus requires a gap or an interruption to perform the measurement.
[0016] It is noteworthy that, although description provided herein may be in the context of certain radio access technologies, networks and network topologies such as LTE, LTE-Advanced, LTE-Advanced Pro, 5G, NR, 5G-Advanced, Internet-of-Things (IoT) , Narrow Band Internet of Things (NB-IoT) , Industrial Internet of Things (IIoT) , beyond 5G (B5G) , and 6th Generation (6G) , the proposed concepts, schemes and any variation (s) / derivative (s) thereof may be implemented in, for and by other types of radio access technologies, networks and network topologies. Thus, the scope of the present disclosure is not limited to the examples described herein.BRIEF DESCRIPTION OF THE DRAWINGS

[0023] 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
[0024] Implementations in accordance with the present disclosure relate to various techniques, methods, schemes and / or solutions pertaining to determining measurement gap requirements 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.
[0025] FIG. 2 illustrates an example of a wireless communications system 200 in accordance with aspects of the present disclosure. The wireless communications system 200 includes base stations 205, UEs 215, and a core network 230. In some examples, the wireless communications system 200 may be a Long-Term Evolution (LTE) network, an LTE-Advanced (LTE-A) network, a 5G network, or a 6G new radio (NR) network. In some cases, wireless communications system 200 may support enhanced broadband communications, ultra-reliable (e.g., mission-critical) communications, low latency communications, or communications with low-cost and low-complexity devices.
[0026] Base stations 205 may wirelessly communicate with UEs 215 via one or more base station antennas. Base stations 205 described herein may include or may be referred to by those skilled in the art as a base transceiver station, a radio base station, an access point, a radio transceiver, a NodeB, an eNodeB (eNB) , a next-generation Node B or giga-nodeB (either of which may be referred to as a gNB) , a Home NodeB, a Home eNodeB, or some other suitable terminology. Wireless communications system 200 may include base stations 205 of different types (e.g., macro or small cell base stations) . The UEs 215 described herein may be able to communicate with various types of base stations 205 and network equipment, including macro eNBs, small cell eNBs, gNBs, relay base stations, and the like.
[0027] Each base station 205 may be associated with a particular geographic coverage area 210 in which communications with various UEs 215 are supported. Each base station 205 may provide communication coverage for a respective geographic coverage area 210 via communication links 225, and communication links 225 between a base station 205 and a UE 215 may utilize one or more carriers. Communication links 225 shown in wireless communications system 200 may include uplink transmissions from a UE 215 to a base station 205, or downlink transmissions from a base station 205 to a UE 215. Downlink transmissions may also be called forward link transmissions, while uplink transmissions may also be called reverse link transmissions.
[0028] The geographic coverage area 210 for a base station 205 may be divided into sectors making up only a portion of the geographic coverage area 210, and each sector may be associated with a cell. For example, each base station 205 may provide communication coverage for a macro cell, a small cell, a hot spot, or other types of cells, or various combinations thereof. In some examples, a base station 205 may be movable and therefore provide communication coverage for a moving geographic coverage area 210. In some examples, different geographic coverage areas 210 associated with different technologies may overlap, and overlapping geographic coverage areas 210 associated with different technologies may be supported by the same base station 205 or by different base stations 205. The wireless communications system 200 may include, for example, a heterogeneous LTE / LTE-A, 5G, or 6G NR network in which different types of base stations 205 provide coverage for various geographic coverage areas 210.
[0029] The term “cell” refers to a logical communication entity used for communication with a base station 205 (e.g., over a carrier) and may be associated with an identifier for distinguishing neighboring cells (e.g., a physical cell identifier (PCID) , a virtual cell identifier (VCID) ) operating via the same or a different carrier. In some examples, a carrier may support multiple cells, and different cells may be configured according to different protocol types (e.g., machine-type communication (MTC) , narrowband Internet-of-Things (NB-IoT) , enhanced mobile broadband (eMBB) , or others) that may provide access for different types of devices. In some cases, the term “cell” may refer to a portion of a geographic coverage area 210 (e.g., a sector) over which the logical entity operates.
[0030] UEs 215 may be dispersed throughout the wireless communications system 200, and each UE 215 may be stationary or mobile. A UE 215 may also be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable terminology, where the “device” may also be referred to as a unit, a station, a terminal, or a client. A UE 215 may also be a personal electronic device such as a cellular phone, a personal digital assistant (PDA) , a tablet computer, a laptop computer, or a personal computer. In some examples, a UE 215 may also refer to a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or an MTC device, or the like, which may be implemented in various articles such as appliances, vehicles, meters, or the like.
[0031] Base stations 205 may communicate with the core network 230 and with one another. For example, base stations 205 may interface with the core network 230 through backhaul links 232 (e.g., via an S1, N2, N3, or other interface) . Base stations 205 may communicate with one another over backhaul links 234 (e.g., via an X2, Xn, or other interface) either directly (e.g., directly between base stations 205) or indirectly (e.g., via core network 230) .
[0032] The core network 230 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 230 may be an evolved packet core (EPC) , which may include at least one mobility management entity (MME) , at least one serving gateway (S-GW) , and at least one Packet Data Network (PDN) gateway (P-GW) . The MME may manage non-access stratum (e.g., control plane) functions such as mobility, authentication, and bearer management for UEs 215 served by base stations 205 associated with the EPC. User IP packets may be transferred through the S-GW, which itself may be connected to the P-GW. The P-GW may provide IP address allocation as well as other functions. The P-GW may be connected to the network operators'IP services. The operator's IP services may include access to the Internet, Intranet (s) , an IP Multimedia Subsystem (IMS) , or a Packet-Switched (PS) Streaming Service.
[0033] At least some of the network devices, such as a base station 205, may include subcomponents such as an access network entity, which may be an example of an access node controller (ANC) . Each access network entity may communicate with UEs 215 through a number of other access network transmission entities, which may be referred to as a radio head, a smart radio head, or a transmission / reception point (TRP) . In some configurations, various functions of each access network entity or base station 205 may be distributed across various network devices (e.g., radio heads and access network controllers) or consolidated into a single network device (e.g., a base station 205) .
[0034] In wireless communications system 200, base station 205 or UE 215 may be equipped with multiple antennas, which may be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. For example, wireless communications system 200 may use a transmission scheme between a transmitting device (e.g., a base station 205) and a receiving device (e.g., a UE 215) , where the transmitting device is equipped with multiple antennas and the receiving devices are equipped with one or more antennas. MIMO communications may employ multipath signal propagation to increase the spectral efficiency by transmitting or receiving multiple signals via different spatial layers, which may be referred to as spatial multiplexing.
[0035] The multiple signals may, for example, be transmitted by the transmitting device via different antennas or different combinations of antennas. Likewise, the multiple signals may be received by the receiving device via different antennas or different combinations of antennas. Each of the multiple signals may be referred to as a separate spatial stream and may carry bits associated with the same data stream (e.g., the same codeword) or different data streams. Different spatial layers may be associated with different antenna ports used for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO) , where multiple spatial layers are transmitted to the same receiving device, and multiple-user MIMO (MU-MIMO) , where multiple spatial layers are transmitted to multiple devices.
[0036] Wireless communications system 200 may support efficient techniques for determining measurement gap requirements. In accordance with one novel aspect, the UE 215 may determine whether the UE 215 requires a gap or an interruption to perform a measurement in an event that a measurement is configured in the MO received from the base station 205. Specifically, the UE 215 may transmit an indication associated with the MO (i.e., per-MO indication) to the base station 205 to indicate whether the UE requires a gap or an interruption to perform the measurement.
[0037] FIG. 3 is a flowchart illustrating a procedure by which a UE determines and reports a measurement gap requirement to a base station in accordance with aspects of the present disclosure.
[0038] Referring to step S305, the UE receives a radio resource control (RRC) message (e.g., RRCReconfiguration) from the base station. The RRC message comprises a measurement object (MO) . The MO may include configuration information for the target frequency, specifying one or more frequency resources on which the UE may perform measurements. The configuration information for the target frequency may comprise at least one target carrier frequency, which may be represented using an absolute radio-frequency channel number (ARFCN) or an equivalent frequency index. The configuration information for the target frequency may further indicate a subcarrier spacing associated with the target carrier, an operating bandwidth or frequency range supported for measurements on the target carrier, or both. In certain embodiments, the configuration information for the target frequency may additionally identify at least one frequency position of reference signals within the target carrier, such as a frequency location corresponding to a synchronization signal block (SSB) or a channel state information reference signal (CSI-RS) . By including such information, the MO may enable the UE to determine the frequency domain scope for the measurement, to identify the measurement resources within the target carrier, and to assess whether a measurement gap, interruption, or other reception adjustment may be required to conduct the measurement. In addition, in the context of the present disclosure, the measurement is configured in the MO. This means that the MO provides the necessary configuration information for the UE to perform the measurement.
[0039] In step S310, in response to the UE being configured by the base station with the MO, the UE determines the requirements for performing the measurement configured in the MO. Specifically, the UE determines whether a gap and / or an interruption is required to perform the measurement.
[0040] In step S315, the UE may then transmit a per MO indication associated with the MO to the base station via a complete message (e.g., RRCReconfigurationComplete) . The per MO indication may indicate whether a gap and / or interruption, or alternatively no gap or no interruption, is required for performing the measurement.
[0041] In one embodiment, the per MO indication associated with the MO transmitted by the UE to the base station may include a gap indication, an interruption indication, a no-gap indication, and / or a no-interruption indication. Specifically, the gap indication is transmitted in an event that the UE determines that a measurement gap is required to perform the measurement configured in the MO. The interruption indication is transmitted in an event that the UE determines that an interruption is required to perform the measurement. Conversely, the no-gap indication is transmitted in an event that the UE determines that a measurement gap is not required to perform the measurement. Furthermore, the no-interruption indication is transmitted in an event that the UE determines that neither a measurement gap nor an interruption is required to perform the measurement. Based on the received indication, the base station may optimize the scheduling for the UE.
[0042] In one embodiment, a specific scenario is considered where the UE is configured by the base station with the MO. In this scenario, a center frequency of a reference signal or an SSB of the MO is located within a target band that has been previously reported in a gap indication via a NeedForGap Information Element (IE) . Under these conditions, the UE may determine whether and how to report the per MO indication based on different strategies described below.
[0043] In some embodiments, the per MO indication is transmitted by the UE to the base station based on the reference signal or the SSB of the MO, regardless of whether the previous per target band gap indication has been transmitted by the UE via the NeedForGap IE for the target band containing the reference signal or the SSB. In such embodiments, the per MO indication is transmitted by the UE based on the reference signal or the SSB of the MO only. This ensures that the base station receives an explicit indication for the specific MO.
[0044] In some embodiments, the per MO indication is transmitted by the UE to the base station based on both the reference signal or the SSB of the MO and the previous per target band gap indication reported via the NeedForGap IE for the target band containing the reference signal or the SSB of the MO.
[0045] In other embodiments, the per MO indication is transmitted by the UE to the base station only in an event that the per MO indication is different from the previous per target band gap indication in the NeedForGap IE for the target band containing the reference signal or the SSB of the MO. For example, in an event that the UE has previously transmitted "gap" as the per target band gap indication in the NeedForGap IE, but the UE determines that the new gap indication for the specific MO is "no-gap" , the UE may transmit the new gap indication for the MO. In another example, in an event that the UE has previously transmitted "no-gap" as the gap indication in the NeedForGap IE, and the UE determines that the new gap indication for the specific MO is also "no-gap" , the UE may not transmit the new gap indication for the MO.
[0046] In some embodiments, a specific scenario is considered where the UE is configured by the base station with the MO, and the center frequency of the reference signal or the SSB in the MO is not located within any target band indicated in the NeedForGap IE.
[0047] In some embodiments, in an event that the center frequency is not located within any target band indicated in the NeedForGap IE, the per MO indication is transmitted by the UE to the base station based on the reference signal or the SSB of the MO, regardless of whether the previous per target band gap indication has been transmitted via the NeedForGap IE for a band containing the reference signal. Specifically, the per MO indication is transmitted by the UE based on the reference signal or the SSB of the MO only.
[0048] In some embodiments, the scope of the measurements performed by the UE covers various cell types. Specifically, the UE performs the measurement configured in the MO for a serving cell and / or a target neighboring cell. The serving cells may include a primary cell (PCell) , a primary secondary cell (PSCell) , or a secondary cell (SCell) .
[0049] In some embodiments, the UE transmits the per MO indication to the base station in response to a control message. The control message may be, for example, an RRC reconfiguration message, downlink control information (DCI) , and / or a medium access control-control element (MAC-CE) . This mechanism allows the base station to dynamically trigger the UE to update the UE’s gap or interruption requirements based on the latest configuration changes.
[0050] In some embodiments, the MO is configured to the UE specifically for performing at least one of a layer 3 (L3) measurement and a layer 1 (L1) measurement. The L3 measurement may include, but is not limited to, an intra-frequency measurement, an inter-frequency measurement, or an inter-radio access technology (inter-RAT) measurement. The L1 measurement may include, but is not limited to, a radio link monitoring (RLM) , a beam failure detection (BFD) , or an L1-RSRP measurement. Illustrative Implementations

In which, communication apparatus 410 is implemented in or as a communication apparatus or a UE, and network apparatus 420 is implemented in or as a network node of a communication network (e.g., a base station) . Illustrative Processes
[0058] FIG. 5 illustrates an example process 500 in accordance with an implementation of the present disclosure. Process 500 may be an example implementation of the above scenarios / schemes, whether partially or completely, with respect to determining measurement gap requirements. Process 500 may represent an aspect of the implementation of features of communication apparatus 410. Process 500 may include one or more operations, actions, or functions as illustrated by one or more of blocks 510 and 520. Although illustrated as discrete blocks, various blocks of process 500 may be divided into additional blocks, combined into fewer blocks, or eliminated, depending on the desired implementation. Moreover, the blocks of process 500 may be executed in the order shown in FIG. 5 or, alternatively, in a different order. Process 500 may be implemented by communication apparatus 410 or any suitable UE (e.g., UE 215) or machine-type devices. Solely for illustrative purposes and without limitation, process 500 is described below in the context of communication apparatus 410 as a UE. Process 500 may begin at block 510.
[0059] At block 510, process 500 may involve processor 412 of communication apparatus 410 receiving, via transceiver 416, a measurement object (MO) from a network node (e.g., network apparatus 420) . Process 500 may proceed from block 510 to block 520.
[0060] At block 520, process 500 may involve processor 412 transmitting, via transceiver 416, a per MO indication to the network node for a measurement configured in the MO, wherein the per MO indication indicates whether the communication apparatus 410 requires a gap or an interruption to perform the measurement.
[0061] In some implementations, the per MO indication is associated with the MO and indicates that a gap is needed, or an interruption is needed, or no gap is needed, or no interruption is needed for performing the measurement.
[0062] In some implementations, in an event that a center frequency of a reference signal or an SSB of the MO is located within a target band and a previous per target band gap indication has been reported for the target band, the per MO indication is transmitted to the network node based on the reference signal or the SSB of the MO regardless of whether the previous per target band gap indication has been transmitted.
[0063] In some implementations, in an event that a center frequency of a reference signal or an SSB of the MO is located within a target band, and a previous per target band gap indication has been reported for the target band, the per MO indication is transmitted to the network node based on the reference signal or the SSB of the MO and the previous per target band gap indication.
[0064] In some implementations, the per MO indication is transmitted in an event that the per MO indication is different from the previous per target band gap indication.
[0065] In some implementations, in an event that a center frequency of a reference signal or an SSB of the MO is not located within a target band, the per MO indication is transmitted to the network node based on the reference signal or the SSB of the MO regardless of whether a previous per target band gap indication reported for the target band has been transmitted.
[0066] In some implementations, the measurement is performed for a serving cell or a target neighboring cell.
[0067] In some implementations, the per MO indication is transmitted after at least one of an RRC reconfiguration message, a downlink control information (DCI) and a medium access control-control element (MAC-CE) .
[0068] In some implementations, the per MO indication is transmitted via an RRC reconfiguration complete message.
[0069] In some implementations, the measurement comprises at least one of a layer 3 (L3) measurement and a layer 1 (L1) measurement. Additional Notes
[0070] 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 that 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.
[0071] 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.
[0072] Moreover, it will be understood by those skilled in the art that, in general, terms used herein, and especially in the appended claims, e.g., bodies of the appended claims, are generally intended as “open” terms, e.g., the term “including” should be interpreted as “including but not limited to, ” the term “having” should be interpreted as “having at least, ” the term “includes” should be interpreted as “includes but is not limited to, ” etc. It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases "at least one" and "one or more" to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles "a" or "an" limits any particular claim containing such introduced claim recitation to implementations containing only one such recitation, even when the same claim includes the introductory phrases "one or more" or "at least one" and indefinite articles such as "a" or "an, " e.g., “a” and / or “an” should be interpreted to mean “at least one” or “one or more; ” the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should be interpreted to mean at least the recited number, e.g., the bare recitation of "two recitations, " without other modifiers, means at least two recitations, or two or more recitations. Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc. ” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention, e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and / or A, B, and C together, etc. In those instances where a convention analogous to “at least one of A, B, or C, etc. ” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention, e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and / or A, B, and C together, etc. It will be further understood by those within the art that virtually any disjunctive word and / or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B. ”
