    COMMUNICATION OF MIXED ACCESS MODE FOR INDEPENDENT OPERATION IN A SHARED MEDIA
    CROSS REFERENCE TO RELATED APPLICATIONS [001] This application claims the benefits of US provisional application No. 62 / 395,487, entitled MIXED-ACCESS MODE COMMUNICATION FOR STANDALONE OPERATION ON A SHARED COMMUNICATION MEDIUM, deposited on September 16, 2016, assigned to assignee of this application and expressly incorporated herein by reference in its entirety.
    FUNDAMENTALS [002] Aspects of this description generally refer to telecommunications, and more particularly to operations in a shared media and the like.
    [003] Wireless communication systems are widely developed to provide various types of communication content, such as voice, data, multimedia and so on. Typical wireless communication systems are multiple access systems capable of supporting communication with multiple users by sharing available system resources (for example, bandwidth, transmission power, etc.). Examples of such
    systems in access multiple include systems in Access Multiple per Division Code (CDMA), systems in Access Multiple per Division of time (TDMA), systems in Access
    Frequency Division Multiple (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA) systems, and others. These systems are often deployed in accordance with specifications, such as

    [004] In cellular networks, macro cell access points provide connectivity and coverage for a large number of users across a given geographic area. A macro network deployment is carefully planned, designed and implemented to provide good coverage across the geographic region. To improve internal geographic coverage or other specific geographic coverage, such as for residential and commercial buildings, an additional small cell, typically low-power access points, has recently been developed to supplement conventional macro networks. Small cell access points can also provide increased capacity growth, a richer user experience, and so on.
    [005] Small cell operations have been extended to the so-called unlicensed frequency spectrum, and slightly licensed, for example, such as the National Unlicensed Information Infrastructure (U-NII) band and the Radio Service band of Broadband for Citizens (GB). This extension of the small cell operation is designed to increase spectral efficiency and thus the capacity of the system as a whole. However, it can also result in varying degrees

    DETAILED DESCRIPTION [0022] This description generally refers to the communication of mixed access mode on a shared communication medium. In order to more effectively mitigate interference between devices belonging to different operators, a central coordination controller or similar can divide the communication medium into a competition-free partition, in which devices without mechanisms of coexistence Through-the-Air (OTA), such as Listen Before You Speak (LBT), can be developed and a competition-based partition, in which the devices have OTA competition capabilities, can be developed. In order to take advantage of the benefits of both, and increase spectral efficiency as a whole, some operators can be developed to occupy the resources in both the competition-free partition and the competition-based partition. For example, a given operator's access point and access terminal can communicate via the Primary Cell (PCell) deployed in the competition-based partition. Each cell can operate according to a Time Division Duplexing (TDD) configuration in the time domain, with the TDD configuration of one or more

    SCells (s) being fixed to that of PCell or adaptively depending on the frequency separation between the competition-free partition and the competition-based partition.
    [0023] More specific aspects of the description are provided in the following description and related drawings directed to various examples provided for purposes of illustration. Alternative aspects can be glimpsed without departing from the scope of the description. In addition, well-known aspects of the description may not be described in detail or may be omitted so as not to obscure the most relevant details.

For example, data, instructions, commands, information, signals, bits, symbols and chips that can be referenced throughout the description below can be represented by voltages,

    [0026] Figure 1 is a system level diagram illustrating a wireless network environment, illustrated by way of example as including two operator systems, a first A 100 operator system and a second B 150 operator system. Each system can be made up of different wireless nodes generally capable of receiving and / or transmitting over a wireless link, including information related to various types of communication (for example, voice, data, multimedia services, associated control signaling, etc.). ). The operator system A 100 is illustrated including an access point 110 and an access terminal 120 communicating with each other over a wireless link 130. The operator system B 150 is illustrated as including its own access point 160 and access terminal 170 communicating with each other via a separate wireless link 132.
    [0027] As an example, access point 110 and access terminal 120 of operator system A 100 can communicate over wireless link 130 according to Long Term Evolution (LTE) technology or a variation thereof (for example, MuLTEfire, Licensed Assisted Access (LAA), etc.), while access point 160 and access terminal 170 of operator system B 150 can communicate over wireless link 132, according to the same technology LTE or a different technology (for
    Petition 870190022439, of 03/08/2019, p. 13/58
    9/31 example, Wi-Fi technology), but developed by a different operator (for example, a different company or other entity controlling authorization, system timing, etc.). It will be appreciated that each system can support any number of wireless nodes distributed across an entire geographic region with the illustrated entities being illustrated for purposes of illustration only.
    [0028] Unless otherwise noted, the terms access terminal and access point should not be specific or limited to any particular Radio Access Technology (RAT). In general, access terminals can be any wireless communication device that allows a user to communicate over a communications network (for example, a mobile phone, router, personal computer, server, entertainment device, Internet of Things (IOT) / device capable of Internet of Everything (IOE), in-vehicle communication device, etc.) and can be any one, alternatively referred to in different RAT environments as a User Device (UD), a Mobile Station ( MS), a Subscriber Station (STA), User Equipment (UE), etc. Similarly, an access point can operate according to one or more RATs when communicating with the access terminals, depending on the network in which the access point is developed, and can alternatively be referred to in different RAT environments, such as a User Device (UD), a Mobile Station (MS), a Subscriber Station (STA), a User Equipment (UE), etc. Similarly, an access point can operate according to one or more RATs in the communication
    Petition 870190022439, of 03/08/2019, p. 14/58
    10/31 with access terminals depending on the network in which the access point is developed, and can alternatively be referred to as a Base Station (BS), a Network Node, a NodeB, an evolved NodeB (eNB), etc. Such an access point can correspond to a small cell access point, for example. Small cells generally refer to a class of low power access points that may include or otherwise be referred to as femto cells, pico cells, micro cells, Wireless Local Area Network (WLAN) access points, other points small coverage area access, etc. Small cells can be developed to supplement macro cell coverage, which can cover few blocks within a neighborhood or several square kilometers in a rural setting, resulting in improved signaling, increased capacity growth, better user experience, and so on. .
    [0029] Returning to figure 1, the wireless link 130 used by the operator system A 100 and the wireless link 132 used by the operator system B 150 can operate through a shared communication medium 140. Such a communication medium it can be composed of one or more communication resources of frequency, time and / or space (for example, encompassing one or more channels through one or more carriers). As an example, communication means 140 may correspond to at least part of an unlicensed or slightly licensed frequency band. Although different licensed frequency bands have been reserved for certain communications (for example, by a government entity
    Petition 870190022439, of 03/08/2019, p. 15/58
    11/31 such as the Federal Communications Commission (FCC) in the United States), some systems, in particular those that use small cell access points, have an extended operation for unlicensed or slightly licensed customer bands, such as Unlicensed National Information Infrastructure band (UNII) and the Citizen Broadband Radio Service band (CB).
    [0030] Due to the shared use of communication medium 140, there is a potential for the appearance of cross link interference between wireless link 130 and wireless link 132, particularly if one of the operator systems A 100 and / or the B 150 operator system does not support mechanisms of coexistence or coordination through the air (OTA), such as competition or Listen Before Speaking (LBT) to arbitrate access to the media 140. As an example, a Released Channel (CCA) can be used, in which each device checks, through the medium that perceives the absence of other traffic in a shared communication medium, before closing (and, in some cases, reserving) the communication medium for its transmissions themselves. While OTA coexistence mechanisms can improve spectral efficiency and, therefore, overall capacity compared to a strict operator-based partition of the media 140, they can introduce latencies that are undesirable for some applications (for example , high quality of service (QoS) traffic such as voice traffic), and, in any case, not all operators and devices can support coexistence
    Petition 870190022439, of 03/08/2019, p. 16/58
    12/31
    OTA.
    [0031] Accordingly, in some projects, a central coordination server 180, such as the Spectrum Access Server (SAS) can be developed to more intelligently divide media 140 in order to mitigate interference. The partition can also be adapted as needed (for example, on a slow time scale or based on a triggered event). As illustrated in figure 1, the central coordination server 180 can communicate the partition to the operator system A 100 through a respective return access channel link 182 and to the operator system B 150 through an access channel link of respective return 184.
    [0032] Figure 2 illustrates an illustrative partition scheme that can be implemented on the communication medium 140. As illustrated, the communication medium 140 can generally be divided by the central coordination server 180 into a competition-free partition 202, where the devices without OTA competition capabilities can be deployed and a competition-based partition 204, in which devices with OTA competition capabilities can be developed. The competition-free partition 202 and the competition-based partition 204 can be separated by a protective band (GB) region 206 to reduce cross-interference.
    [0033] In the illustrated example, competition-free partition 202 is subdivided into a first dedicated subpartition 212 reserved for a first operator (OP-1), a second dedicated subpartition 214 reserved for a second operator (OP-2), and a third
    Petition 870190022439, of 03/08/2019, p. 17/58
    13/31 dedicated subpart 216 reserved for a third operator (OP-3). The competition-based partition 204 includes a shared partition 218 that is opened for competition-based access by a fourth operator (OP-
    4), a fifth operator (OP-5) and a sixth operator (OP-6). It will be appreciated that the number of operators, the layout of the operators and the relative bandwidths occupied by different partitions and subpartitions can be adapted, statically or dynamically, for any given application, as desired.
    [0034] The competition free partition 202 provides relatively free bandwidth, although reduced, for the first, second and third operators. Meanwhile, the competition-based partition 204 provides access to greater, though less reliable, bandwidth for the fourth, fifth and sixth operators.
    [0035] Returning to figure 2, as an additional improvement, some operators can be developed in order to occupy the resources in both the competition-free partition 202 and the competition-based partition 204 in order to take advantage of the benefits of each . In the illustrated example, the wireless link 130 between access point 110 and access terminal 120 of operator system A 100 can be adapted to communicate through the third dedicated subpartition 216 of the competition-free partition 202 (for example, effectively as the third operator (OP-3)) and also to communicate through shared partition 218 of the competition-based partition 204 (for example, effectively as the fourth operator (OP-4) as well). In other words, OP-3 and OP-4
    Petition 870190022439, of 03/08/2019, p. 18/58
    14/31 can represent the same operator (for example, operator A) in this example, with operator A allocated with both resources free of competition and based on competition between the respective partitions 202 and 204. This mixed access mode of communication can be implemented in different ways.
    [0036] Figure 3 illustrates an illustrative mixed access mode communication scheme that can be implemented for operator system A 100 in communication medium 140. In this example, access point 110 can operate wireless link 130 with the access terminal 120 through a plurality of cells, including a Primary Cell (PCell) 302 and one or more Secondary Cells (SCell (s)) 304, in respective component carriers (respective frequencies).
    [0037] As illustrated, the PCell connection 302 can operate through the third dedicated subpartition 216 of the competition-free partition 202, for example, and one or more SCell connections (s) 304 can operate through the shared partition 218 of the partition based on competition 204. In this way, PCell 302 can act as an anchor carrier similar to a licensed anchor (for example, as in LAA) and benefit from having significantly reduced interference from other operators. As an example, PCell 302 can operate using LTE, similar to the licensed LTE operation, and one or more SCell (s) 304 can operate using LAA as a LAA type SCell. The PCell 302 may therefore be suitable for carrying uplink and downlink control information, QoS sensitive traffic, another important signal (for example, mobility),
    Petition 870190022439, of 03/08/2019, p. 19/58
    15/31 etc. The one or more SCell (s) 304 may be suitable to carry other remaining data traffic and provide additional capacity for wireless link 130, which can carry other signaling as needed.
    [0038] In such a mixed access mode communication scheme, a relatively small bandwidth can be allocated to the competition-free partition 202 including PCell 302 and a relatively large bandwidth can be allocated to the competition-based partition 204 including one or more SCell (s) 304 (for example, by central coordination server 180). This can help improve spectral efficiency and, therefore, overall capacity, by proportionally allocating more bandwidth to the competition-based partition more efficiently 204. Furthermore, if all operators in a local region use this scheme of mixed access mode communication, so even less bandwidth can be allocated to the competition-free partition 202 including PCell 302 and even greater bandwidth can be allocated to the competition-based partition 204 including one or more SCell (s) 304.
    [0039] For an operator in mixed mode, some SCell can also be in the competition-free spectrum.
    [0040] Figure 4 is a timing diagram illustrating an illustrative Time Division Duplexing (TDD) frame structure that can be implemented for the A 100 operator system on communication medium 140.
    [0041] In general, both PCell 302 and one or more SCells 304 can be divided into time domain in
    Petition 870190022439, of 03/08/2019, p. 20/58
    16/31 a series of radio frames (RFs) and respective subframes (SFs). As an example, the LTE frame structure includes system frames that are divided into 1024 numbered radio frames composed of 10 subframes each, which together constitute a system frame cycle (for example, duration of 10.24 s for frames of 10 ms radio with 1 ms subframes).
    [0042] The illustrative frame structure of figure 4 is TDD since each subframe can be operated in different ways at different times as a downlink (D), uplink (U) or special (S) subframe. In general, downlink subframes are reserved for transmission of downlink information (for example, from access point 110 to access terminal 120), uplink subframes are reserved for transmission of uplink information (for example, from terminal access points 120 for access point 110) and special subframes can include a downlink part and an uplink part separated by a protection period. Different arrangements of downlink, uplink and special subframes can be referred to as different TDD configurations. Returning to the LTE example above, the TDD variation of the LTE frame structure includes 7 TDD configurations (TDD Config 0 to TDD Config 6), with each configuration having a different arrangement of downlink, uplink and special subframes. For example, some TDD configurations may have more downlink subframes and some may have more uplink subframes to accommodate different traffic situations. In the example shown in figure 4, a TDD configuration is used, similar to TDD Config 3 in LTE.
    Petition 870190022439, of 03/08/2019, p. 21/58
    17/31 [0043] Returning to figure 4, in the illustrated example, the TDD configurations for PCell 302 and one or more SCell (s) 304 are synchronized to a common TDD configuration (TDD Configuration Ά ') to avoid auto interference. While some technologies, such as MuLTEfire, may allow for a more flexible frame structure, a synchronized and thus fixed TDD configuration, it can help reduce interference for the PCell 302 while still providing greater bandwidth for one or more SCell (s) 304.
    [0044] For competition-based partition 204, access point 110 can compete for access to communication medium 140 for one or more SCell (s) 304 based on the location of the downlink subframes within the frame structure. Access terminal 120 can similarly compete for access to communication means 140, as needed, based on the location of the uplink subframes within the frame structure.
    [0045] Furthermore, the same TDD configuration can be designated for multiple operators (for example, for the A 100 operator system and the B 150 operator system), so that, in some designs or situations, essentially the entire communication medium 140 can be operated with the same TDD configuration through PCells and SCells from different operators.
    [0046] Figure 5 is another timing diagram illustrating another illustrative TDD frame structure that can be implemented for the operator system A 100 in communication medium 140. As in the example in figure 4, both PCell 302 and one or more SCell (s) 304
    Petition 870190022439, of 03/08/2019, p. 22/58
    18/31 can be divided in the time domain into a defined sequence or series of radio frames (RFs) and respective subframes (SFs) organized in a TDD configuration having a determined arrangement of downlink, uplink and special subframes.
    [0047] In this example, however, PCell 302 and one or more SCell (s) 304 can operate according to different TDD configurations (TDD Config Ά 'or' B '). For example, PCell 302 may employ a TDD configuration similar to TDD Config 1 in LTE, when one or more SCell (s) 304 may employ a TDD configuration similar to TDD Config 3 in LTE. Or, the TDD configuration of one or more SCell (s) 304 can be completely flexible, as in MuLTEfire or Embedded Linus & Android Alliance (eLAA), where it can be dynamically changed with each transmission burst by the access point 110.
    [0048] This design may be suitable when the communication medium 140 comprises two different frequency bands (for example, the 3.5 GHz CB band and the 5 GHz UNII band), or, more generally, when the protection bandwidth (GB) 206 is large enough (for example, above a threshold) to substantially isolate the competition-free partition 202 and the competition-based partition 204 from downlink cross-over to uplink or from uplink to downlink. Thus, the TDD configuration of one or more SCell (s) 304 can be fixed or adaptive depending on the separation between the competition-free partition 202 and the competition-based partition 204.
    [0049] Figure 6 is a flow chart illustrating
    Petition 870190022439, of 03/08/2019, p. 23/58
    19/31 an illustrative method 600 of communication, according to the techniques described above. Method 600 can be carried out, for example, by a central coordination server (for example, central coordination server 180 illustrated in figure 1), such as a SAS.
    [0050] As illustrated, the central coordination server can divide a shared communication medium (for example, shared communication medium 140) into a competition-free partition (for example, competition-free partition 202 of figure 2) where the medium Shared communication is reserved for devices (for example, access point 110 and / or access terminal 120) associated with a first set of operators (for example, OP-1, OP-2 and OP-3 in figures 2 and 3) and a competition-based partition (for example, competition-based partition 204 of figure 2) where devices (for example, access point 110 and / or access terminal 120) associated with a second set of operators (for example, OP-4, OP-5 and OP-6 in figures 2
    and 3) compete by access to middle of Communication shared according to with one protocol based in competition (for example, such how the access multiple in
    carrier sensor or CSMA) (block 602). In addition, at least one operator belongs to both the first and second sets of operators, as described above, with respect to operator A in figures 2 and 3.
    [0051] With reference to figure 6, the central coordination server can notify (directly or indirectly) the devices associated with the first set of operators and the devices associated with the
    Petition 870190022439, of 03/08/2019, p. 24/58
    20/31 second set of partition operators (block 604). For example, block 604 notifications can find out which dedicated subpartitions between the competition free period are allocated to private operators, and can find out which operators can compete for access to the shared media, according to the competition-based protocol. Block 604 notifications can be sent to the return access channel link 182 and / or access channel link 184 of figure 1.
    [0052] Figure 7 is a flow chart illustrating an illustrative method 700 of communication, according to the techniques described above. Method 700 can be carried out, for example, by an access point (for example, access point 110 shown in figure 1) or an access terminal (for example, access terminal 120 shown in figure 1) operating on a shared means of communication.
    [0053] As illustrated, the access point or access terminal can communicate, in association with a first operator, through a competition-free partition of a shared communication medium that is reserved for the first operator (block 702). The access point or access terminal can also communicate, in association with the first operator, through a competition-based partition of the shared communication medium that is shared with a plurality of operators (block 704). For example, the first operator with respect to figure 7 can correspond to operator A as described above with respect to figures 2 and 3.
    [0054] As an example, communication through the competition-free partition (block 702) can
    Petition 870190022439, of 03/08/2019, p. 25/58
    21/31 understanding communication through a PCell and communication through the competition-based partition (block 704) can understand communication through one or more SCell (s). In addition, communications occurring in blocks 702 and 704 in figure 7 can occur in response to a partition notification from a central coordination server, as described above with respect to block 604 in figure 6.
    [0055] For general purposes, the access point 110 and the access terminal 120 are illustrated in figure 1 only in the relevant part. It should be appreciated, however, that access point 110 and access terminal 120 can be configured in various ways to provide, or otherwise support, the mixed access mode communication techniques discussed here.
    [0056] Figure 8 is a device level diagram illustrating illustrative components of access point 110 and access terminal 120 of operator system A 100 in more detail. As illustrated, access point 110 and access terminal 120 can each generally include a wireless communication device (represented by communication devices 830 and 850) to communicate with other wireless nodes via at least one RAT projected. Communication devices 830 and 850 can be configured in various ways to transmit and encode signals, and conversely, to receive and decode signals according to the projected RAT (for example, messages, indications, information, pilots and so on) .
    [0057] Communication devices 830 and
    Petition 870190022439, of 03/08/2019, p. 26/58
    22/31
    850 may include, for example, one or more transceivers, such as the respective primary RAT transceivers 832 and 852 and, in some designs, secondary RAT transceivers of the same location (optional) 834 and 854, respectively (corresponding, for example, to RAT employed by the B 150 operator system). As used here, a transceiver can include a transmitting circuit, a receiving circuit, or a combination thereof, but it does not need to provide transmit and receive functionality in all projects. For example, a low functionality receiver circuit can be employed in some projects to reduce costs when providing full communication is not necessary (for example, a radio chip or similar circuitry providing low level sniffing only). Additionally, as used here, the term of the same location (for example, radios, access points, transceivers, etc.) can refer to one of several provisions. For example, components that are in the same housing; components that are hosted by the same processor; components that are at a defined distance from each other; and / or components that are connected via an interface (for example, an Ethernet switch), where the interface meets the latency requirements of any necessary intercomponent communication (for example, sending messages).
    Access point 110 and access terminal 120 can each also generally include a communication controller (represented by communication controllers 840 and 860) to control the
    Petition 870190022439, of 03/08/2019, p. 27/58
    23/31 operation of their respective communication devices 830 and 850 (for example, targeting, modification, activation, deactivation, etc.). Communication controllers 840 and 860 can include one or more processors 842 and 862, and one or more memories 844 and 864 coupled to processors 842 and 862, respectively. Memories 844 and 864 can be configured to store data, instructions or a combination of them as built-in temporary storage memory, as separate components, a combination, etc. Processors 842 and 862 and memories 844 and 864 may be independent communication components or may be part of the functionality of the respective host system of access point 110 and access terminal 120.
    [0059] Accordingly, it will be appreciated that the components in figure 8 can be used to perform the operations described above with respect to figures 1 to
    7. For example, access point 110 can communicate, via the primary RAT transceiver 832 and in association with a first operator, through a competition-free partition of a shared communication medium that is reserved for the first operator. Access point 110 can also communicate, via the primary RAT transceiver 832 and in association with the first operator, through a competition-based partition of the shared communication medium that is shared with a plurality of operators.
    [0060] As another example, the access terminal 120 can communicate, through the primary RAT transceiver 852 and in association with a first operator,
    Petition 870190022439, of 03/08/2019, p. 28/58
    24/31 through a competition-free partition of a shared media that is reserved for the first operator. The access terminal 120 can also communicate, via the primary RAT transceiver 852 and in association with
    the first operator, across an based partition in middle competition of communication shared that is shared with a plurality in operators.[0061] A figure 9 is one level diagram in
    device illustrating illustrative components of the central coordination server 180 (e.g., a SAS) in greater detail. As illustrated, the central coordination server 180 may include a wireless communication device (represented by communication devices 830 and 850), a network communication interface 905, which can be used to communicate over network access channel links. return 182-184 described above with reference to figure 1. In one example, the network communication interface 905 can be a wired transceiver component (for example, an Ethernet card or network switch).
    [0062] With reference to figure 9, the central coordination server 180 additionally includes a controller 910 to control the operation of the central coordination server 180 (for example, directing, modifying, activating, deactivating, etc.). The controller 910 can include at least one processor 915 and a memory 920 coupled to at least one processor 915. The memory 920 can be configured to store data, instructions or a combination thereof, as built-in storage memory, as separate components, a combination, etc.
    Petition 870190022439, of 03/08/2019, p. 29/58
    25/31 [0063] Accordingly, it will be appreciated that the components in figure 9 can be used to perform the operations described above with respect to figures 1 to 6. For example, the central coordination server 180 can, through controller 910 , divide a shared media into a competition-free partition, where the shared media is reserved for
    devices associated with one first set in operators and a partition with base in competition, where the devices associated with one second set in operators compete for access to the Communication shared , according with one protocol based in
    competition, at least one operator belonging to both the first and second sets of operators. The central coordination server 180 can, in addition, through the network communication interface 905, notify the devices associated with a first set of operators and the devices associated with the second set of operators about the partition.
    [0064] Figure 10 illustrates an illustrative device to implement the mixed access mode communication techniques discussed here on a central coordination server, represented as a series of interrelated functional modules. In the illustrated example, apparatus 1000 includes a divider module 1002 and a notification module 1004.
    [0065] The divider module 1002 can be configured to divide a shared media into a competition-free partition, in which the shared media is reserved for
    Petition 870190022439, of 03/08/2019, p. 30/58
    26/31 devices associated with a second set of operations and a competition-based partition, in which devices associated with a second set of operators compete for access to the shared media, according to a competition-based protocol, for least one operator belonging to both the first and the second set of operators. The notification module 1004 can be configured to notify the devices associated with the first set of operators and the devices associated with the second set of operators in the partition.
    [0066] Figure 11 illustrates an illustrative device for implementing the mixed access mode communication techniques discussed here at an access point and / or an access terminal represented as a series of interrelated functional modules. In the illustrated example, apparatus 1100 includes a communication module 1102 and a communication module 1104.
    [0067] The communication module 1102 can be configured to communicate, in association with a first operator, through a competition-free partition of a shared communication medium that is reserved for the first operator. The communication module 1104 can be configured to communicate, in association with the first operator, through a competition based partition of the shared communication medium that is shared with a plurality of operators.
    [0068] The functionality of the modules in figures 10 and 11 can be implemented in several ways consistent with the teachings presented here. In
    Petition 870190022439, of 03/08/2019, p. 31/58
    27/31 some projects, the functionality of these modules can be implemented as one or more electrical components. In some projects, the functionality of these blocks can be implemented as a processing system including one or more processor components. In some projects, the functionality of these modules can be implemented using, for example, at least a part of one or more integrated circuits (for example, an ASIC). As discussed here, an integrated circuit can include a processor, software, other related components, or some combination thereof. In this way, the functionality of different modules can be implemented, for example, as different subsets of an integrated circuit, such as
    many different subsets of one set in modules in software, or a combination From themselves. Beyond addition, it will be appreciated that a particular subset (per example, in an integrated circuit and / or of a set of modules in software) can provide fur any less an part gives
    functionality for more than one module.
    [0069] Additionally, the components and functions represented by figures 10 and 11, in addition to other components and functions described here, can be implemented using any suitable means. Such means can also be implemented, at least in part, using the corresponding structure as taught here. For example, the components described above in conjunction with the module components for figures 10 and 11 can also correspond to the functionality of means for similarly designated. Thus, in some respects, one or more of such means can be implemented
    Petition 870190022439, of 03/08/2019, p. 32/58
    28/31 using one or more of the processor components, integrated circuits, or other suitable structure as taught herein, including as an algorithm. Those skilled in the art will recognize in this description an algorithm represented in the text described above, as well as in sequences of actions that can be represented by pseudocode. For example, the components and functions represented by figures 10 and 11 can include the code to perform the LOAD operation, a COMPARE operation, a RETURN operation, an IF-THEN-ELSE circuit, and so on.
    [0070] It should be understood that any reference to an element using a designation such as first, second and so on, does not generally limit the quantity or order of those elements. Instead, these designations can be used here as a convenient method of distinguishing between two or more elements or cases of an element. Thus, a reference to the first and second elements does not mean that only two elements can be employed or that the first element must precede the second element in some way. In addition, unless otherwise stated, a set of elements may comprise one or more elements. In addition, the terminology of the form at least one of A, B or C or one or more of A, B or C or at least one of the group consisting of A, B and C used in the description or in the claims means A or B or C or any combination of these elements. For example, that terminology can include A, or B or C, or A and B, or A and C, or A and B and C, or 2A, or 2B or 2C, and so on.
    Petition 870190022439, of 03/08/2019, p. 33/58
    29/31 on.
    [0071] In view of the descriptions and explanations above, those skilled in the art will appreciate that the various illustrative logic blocks, circuit modules and algorithm steps described with respect to the aspects described here can be implemented as electronic hardware, computer software, or combinations of themselves. In order to clearly illustrate this ability to exchange hardware and software, several illustrative components, blocks, modules, circuits and steps have been described above generally in terms of their functionality. Whether such functionality is implemented as hardware or software depends on the particular application and the design restrictions imposed on the system as a whole. Those skilled in the art can implement the functionality described in various ways for each particular application, but such implementation decisions should not be interpreted as being responsible for departing from the scope of this description.
    [0072] Accordingly, it will be appreciated, for example, that an appliance or any component of an appliance can be configured (or made operational or adapted) to provide functionality as described here. This can be achieved, for example, by manufacturing (for example, manufacturing) the device or component so that it provides functionality; by programming the device or component so that it provides functionality; or through the use of some other appropriate implementation technique. As an example, an integrated circuit can be manufactured to provide the necessary functionality. As another example, an integrated circuit can be manufactured to withstand
    Petition 870190022439, of 03/08/2019, p. 34/58
    30/31 required functionality and then configured (for example, programmatically) to provide the required functionality. As another example, a processor circuit can execute the code to provide the necessary functionality.
    [0073] Furthermore, the methods, sequences and / or algorithms described in relation to the aspects described here can be embodied directly in hardware, in a software module executed by a processor, or in a combination of the two. A software module can reside in Random Access Memory (RAM), flash memory, Read Only Memory (ROM), Programmable and Erasable Read Only Memory (EPROM), Electrically Programmable and Erasable Read Only Memory (EEPROM), registers , hard disk, removable disk, CD-ROM, or any other form of storage medium known in the art, transient or non-transient. An illustrative storage medium is coupled to the processor so that the processor can read information from, and write information to, the storage medium. Alternatively, the storage medium can be integral to the processor (for example, temporary memory).
    [0074] Accordingly, it will also be appreciated, for example, that certain aspects of the description may include a transient or non-transitory computer-readable medium embodying a method for communication.
    [0075] While the description above illustrates the various illustrative aspects, it should be noted that several changes and modifications can be made to the illustrated examples without departing from the scope defined by
    Petition 870190022439, of 03/08/2019, p. 35/58
    31/31 attached claims. The present description should not be limited to specifically illustrated examples only. For example, unless noted otherwise, the functions, steps and / or functions of the method claims, in accordance with the aspects of the description described here do not need to be performed in any particular order. Additionally, although certain aspects may be described or claimed in the singular, the plural is contemplated unless the limitation to the singular is explicitly mentioned.
