[0016] 1. Mobile communication technology and environment

[0017] Figure 1 An example wireless communication network and / or system 100 is shown in accordance with an embodiment of the present disclosure, in which the techniques disclosed herein may be implemented. In the following discussion, the wireless communication network 100 may be any wireless network, such as a cellular network or a narrowband Internet of Things (NB-IoT) network, and is referred to herein as "network 100". Such an example network 100 includes a base station 102 (hereinafter referred to as "BS 102"; also referred to as a wireless communication node) and a user equipment 104 (hereinafter referred to as "UE 104"; also referred to as a wireless communication device) that may communicate with each other via a communication link 110 (e.g., a wireless communication channel), and a cluster of cells 126, 130, 132, 134, 136, 138, and 140 covering a geographic area 101. In Figure 1 1, BS 102 and UE 104 are contained within the respective geographic boundaries of cell 126. Each of the other cells 130, 132, 134, 136, 138, and 140 may include at least one base station operating with its allocated bandwidth to provide adequate radio coverage to its intended users.

[0018] For example, BS 102 may operate on an allocated channel transmission bandwidth to provide adequate coverage to UE 104. BS 102 and UE 104 may communicate via downlink radio frames 118 and uplink radio frames 124, respectively. Each radio frame 118 / 124 may be further divided into subframes 120 / 127, which may include multiple data symbols 122 / 128. In the present disclosure, the present application describes BS 102 and UE 104 as non-limiting examples of "communication nodes", which may generally practice the methods disclosed in the present application. According to various embodiments of the present solution, such communication nodes may be capable of wireless and / or wired communication.

[0019] Figure 2A block diagram of an example wireless communication system 200 for sending and receiving wireless communication signals (e.g., OFDM / OFDMA signals) according to some embodiments of the present solution is shown. The system 200 may include components and elements configured to support known or conventional operating features that need not be described in detail herein. In one illustrative embodiment, as described above, the system 200 may be used in applications such as Figure 1 The wireless communication environment 100 may be used to communicate (eg, transmit and receive) data symbols.

[0020] The system 200 generally includes a base station 202 (hereinafter referred to as "BS 202") and a user equipment 204 (hereinafter referred to as "UE 204"). The BS 202 includes a BS (base station) transceiver module 210, a BS antenna 212, a BS processor module 214, a BS memory module 216, and a network communication module 218, each of which is coupled and interconnected to each other via a data communication bus 220 as needed. The UE 204 includes a UE (user equipment) transceiver module 230, a UE antenna 232, a UE memory module 234, and a UE processor module 236, each of which is coupled and interconnected to each other via a data communication bus 240 as needed. The BS 202 communicates with the UE 204 via a communication channel 250, which can be any wireless channel or other medium suitable for data transmission as described in the present application.

[0021] As will be appreciated by those skilled in the art, the system 200 may also include Figure 2 Modules of any number outside the modules shown. It will be appreciated by those skilled in the art that various illustrative blocks, modules, circuits and processing logics relevant to the embodiments described in the present application can be realized with hardware, computer-readable software, firmware or any actual combination thereof. In order to clearly illustrate this interchangeability and compatibility of hardware, firmware and software, various illustrative components, blocks, modules, circuits and steps are generally described according to their functions. Whether this function is realized as hardware, firmware or software depends on the specific application and design constraints imposed on the entire system. People familiar with the concept described in the present application can realize such function in a manner suitable for each specific application, but such realization decision should not be interpreted as limiting the scope of the present disclosure.

[0022] According to some embodiments, the UE transceiver 230 may be referred to herein as an "uplink" transceiver 230, which includes a Radio Frequency (RF) transmitter and an RF receiver, each including circuitry coupled to an antenna 232. A duplex switch (not shown) may alternatively couple the uplink transmitter or receiver to the uplink antenna in a time duplex manner. Similarly, according to some embodiments, the BS transceiver 210 may be referred to herein as a "downlink" transceiver 210, which includes an RF transmitter and an RF receiver, each including circuitry coupled to an antenna 212. The downlink duplex switch may alternatively couple the downlink transmitter or receiver to the downlink antenna 212 in a time duplex manner. The operation of the two transceiver modules 210 and 230 may be coordinated in time such that the downlink receiver circuit is coupled to the downlink antenna 232 so as to receive transmissions over the wireless transmission link 250 while the downlink transmitter is coupled to the downlink antenna 212. Instead, the operation of the two transceivers 210 and 230 may be coordinated in time such that the downlink receiver coupled to the downlink antenna 212 receives transmissions over the wireless transmission link 250 at the same time as the uplink transmitter coupled to the uplink antenna 232. In some embodiments, tight time synchronization with minimal guard times between changes in duplex direction is provided.

[0023] The UE transceiver 230 and the base station transceiver 210 are configured to communicate via a wireless data communication link 250 and cooperate with an appropriately configured RF antenna arrangement 212 / 232 that can support a specific wireless communication protocol and modulation scheme. In some illustrative embodiments, the UE transceiver 210 and the base station transceiver 210 are configured to support industry standards such as Long Term Evolution (LTE) and emerging 5G standards. However, it should be understood that the present disclosure is not limited to application to specific standards and related protocols. On the contrary, the UE transceiver 230 and the base station transceiver 210 can be configured to support alternative or additional wireless data communication protocols, including future standards or variations thereof.

[0024] According to various embodiments, for example, BS 202 may be an evolved node B (eNB), a serving eNB, a target eNB, a femto base station, or a pico base station. In some embodiments, UE 204 may be embodied in various types of user equipment, such as a mobile phone, a smart phone, a personal digital assistant (PDA), a tablet computer, a laptop computer, a wearable computing device, etc. Processor modules 214 and 236 may be implemented or completed using a general-purpose processor, a content addressable memory, a digital signal processor, an application-specific integrated circuit, a field programmable gate array, any suitable programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof to perform the functions described herein. In this manner, the processor may be implemented as a microprocessor, a controller, a microcontroller, a state machine, etc. The processor may also be implemented as a combination of computing devices, such as a combination of a digital signal processor and a microprocessor, a plurality of microprocessors, one or more microprocessors combined with a digital signal processor core, or any other such configuration.

[0025] In addition, the steps of the method or algorithm described in conjunction with the embodiments of the present application can be directly embodied in hardware, firmware, software modules executed by processor modules 214 and 236, respectively, or any practical combination thereof. Memory modules 216 and 234 can be implemented as RAM memory, flash memory, ROM memory, EPROM memory, EEPROM memory, registers, hard disk, removable disk, CD-ROM, or any other form of storage medium known in the art. In this regard, memory modules 216 and 234 can be coupled to processor modules 210 and 230, respectively, so that processor modules 210 and 230 can read information from and write information to memory modules 216 and 234, respectively. Memory modules 216 and 234 can also be integrated into their respective processor modules 210 and 230. In some embodiments, memory modules 216 and 234 can each include a cache memory for storing temporary variables or other intermediate information during the execution of instructions executed by processor modules 210 and 230, respectively. Memory modules 216 and 234 may also each include non-volatile memory for storing instructions to be executed by processor modules 210 and 230, respectively.

[0026] The network communication module 218 generally represents the hardware, software, firmware, processing logic and / or other components of the base station 202 that enable bidirectional communication between the base station transceiver 210 and other network components and communication nodes configured to communicate with the base station 202. For example, the network communication module 218 can be configured to support Internet or WiMAX services. In a typical deployment, but not limited to, the network communication module 218 provides an 802.3 Ethernet interface so that the base station transceiver 210 can communicate with a traditional Ethernet-based computer network. In this way, the network communication module 218 can include a physical interface for connecting to a computer network (e.g., a mobile switching center (MSC)). The terms "configured for", "configured to" and their variants used in this application for a specific operation or function refer to devices, components, circuits, structures, machines, signals, etc., which are physically constructed, programmed, formatted and / or arranged to perform a specific operation or function.

[0027] The Open Systems Interconnection (OSI) model (referred to herein as the "OSI model") is a conceptual and logical layout that defines network communications used by systems (e.g., wireless communication devices, wireless communication nodes) that are open to interconnection and communication with other systems. The model is divided into seven subcomponents or layers, each representing a conceptual set of services provided to the layers above and below it. The OSI model also defines a logical network and effectively describes computer packet transmission by using different layer protocols. The OSI model may also be referred to as a seven-layer OSI model or a seven-layer model. In some embodiments, the first layer may be a physical layer. In some embodiments, the second layer may be a medium access control (MAC) layer. In some embodiments, the third layer may be a radio link control (RLC) layer. In some embodiments, the fourth layer may be a packet data convergence protocol (PDCP) layer. In some embodiments, the fifth layer may be a radio resource control (RRC) layer. In some implementations, the sixth layer may be one of a non-access stratum (NAS) layer or an Internet Protocol (IP) layer, and the seventh layer is another layer.

It is obvious to a person of ordinary skill in the art that, after reading this disclosure, various changes or modifications can be made to the examples described in this application without departing from the scope of the present solution. Therefore, the present solution is not limited to the exemplary embodiments and applications described and shown in this application. In addition, the specific order or hierarchy of steps in the method disclosed in this application is merely an example method. Based on design preferences, the specific order or hierarchy of the steps of the disclosed method or process can be rearranged while remaining within the scope of the present solution. Therefore, a person of ordinary skill in the art will understand that the methods and techniques disclosed in this application present various steps or actions in a sample order, and unless otherwise explicitly stated, the present solution is not limited to the specific order or hierarchy presented.

[0029] 2. System and method for UE capability reporting

[0030] In some systems (e.g., 5G New Radio (NR), Next Generation (NG) systems, 3GPP systems, and / or other systems), once the UE capabilities have been reported and / or have accessed the network, the characteristics / capabilities of UE 104 (e.g., UE capabilities) can be fixed in the communication. Specifically, after the UE capabilities are reported, it may be challenging to change such characteristics / capability information associated with UE 104. However, given the greater diversity of terminal types, applications, services, scenarios, and / or at least one of the different key performance indicators (KPIs), such as energy efficiency requirements and / or regulatory requirements, it may be desirable to update this information (e.g., UE capabilities) in the communication. The systems and methods of the technical solutions discussed in the present application may provide features, operations, and techniques that enable / support updating / changing / modifying the UE capability information in the communication after the characteristics / capabilities of the UE capabilities have been reported.

[0031] In various implementations, the mode of the UE 104 (e.g., UE mode) may refer to an RRC state (e.g., RRC connected, inactive, or idle) or a motion state (e.g., hovering, flying, stopped, paused, accelerating, high speed, descending, ascending, and / or stationary, etc.) of the UE 104. The UE 104 may determine its mode, for example, based on whether the UE 104 is moving, for example, based on readings / data from a motion sensor of the UE 104 or a change in altitude (e.g., via a barometer). The location / position of the UE 104 may refer to situations where the UE 104 is at different altitudes / heights (e.g., absolute or relative altitudes compared to the ground level or BS level) and / or regions (e.g., in some areas / regions, the transmission power of an airborne UE may be limited to meet regulatory requirements / conditions / standards), for example, deployment of the UE 104.

[0032] In some implementations, the traffic status may refer to the type of traffic transmitted and / or received by the UE 104, such as Ultra-Reliable Low Latency Communication (URLLC), etc. Different services may be indicated by corresponding indicators from at least one of the higher layers of the BS 102 and / or the UE 104. In some other implementations, the traffic status may refer to the Quality of Service (QoS) requirements / statuses of information (e.g., expected) to be transmitted and / or received by the UE 104.

[0033] refer to Figure 3 , depicting an example diagram 300 of regions / areas corresponding to corresponding thresholds. As shown, regions may be defined or associated with corresponding thresholds (e.g., 2D or 3D). For example, the threshold may indicate a location region, such as an altitude / height, latitude and / or longitude boundaries / coordinates of a region, and / or a maximum transmission power (e.g., associated with a specific location region), etc. In this case, the UE 104 may determine its location based on whether the UE 104 is in, exceeds, or is within certain boundaries or thresholds. Therefore, the UE 104 may associate its location with a corresponding region based on the threshold. The threshold may be indicated / provided / configured by a network and / or regulatory requirements. In addition to other network devices, regulatory requirements may be configured for the BS 102. As discussed in the present application, the system and method of the technical solution may update / modify / change / configure reported UE capabilities, for example, in response to changes in the mode and / or location of the UE 104.

[0034] Example Implementation 1

[0035] UE 104 (e.g., an airborne UE, a mobile phone, and / or other terminal) can connect to a network to communicate with one or more BSs 102 (e.g., gNBs). In response to connecting to the network, UE 104 can report a first UE capability set (e.g., a first capability information set) to at least one of the BSs 102.

[0036] In various arrangements, the UE 104 may report / provide a first capability information set that includes various capability subsets (e.g., multiple capability information) associated with the UE 104. Each capability subset may be associated or correspond to different criteria / conditions / parameters, such as a corresponding mode of the UE 104, a corresponding location of the UE 104, and / or a corresponding traffic condition. For example, in addition to other criteria, the capability subset may relate to or be associated with at least one of the number of beams supported for transmission and / or reception (e.g., the number of reference signals (RS) used for corresponding beam measurement), the maximum transmission power (e.g., the UE power class), and / or different values ​​(e.g., assumed to be different capabilities by airborne UEs at different locations). For example, each different value may be associated with a corresponding region. For example, with respect to beam information, no beamforming may be supported at ground level (e.g., in ground level mode). In flight mode, the UE 104 may consider or determine the number of beams supported for transmission. Regarding power level (e.g., maximum transmission power), UE 104 may consider or determine that a power level of 26 dBm is used at ground level, and the power may be reduced to 23 dBm once UE 104 is in flight mode. In some cases, for example, after UE 104 switches from ground level mode to flight mode, UE 104 may reduce the power from 23 dBm to 20 dBm.

[0037] In this case, BS 102 may receive / obtain a subset of capability information from UE 104. UE 104 may monitor or determine a change in a mode and / or location of UE 104, and / or a traffic condition (e.g., URLLC service, enhanced Mobile Broadband (eMBB) and / or Voice over IP (VoIP) service, etc.). In response to the determination, UE 104 may update capability information associated with UE 104 based on the current mode, location and / or traffic condition. For example, UE 104 may update / modify / change from a first set (or subset) of capability information to a second set (or subset) of capability information associated with a mode, location and / or traffic condition determined by UE 104.

[0038] refer to Figure 4, depicts an example flow chart 400 for updating UE capabilities. In some arrangements, UE 104 may report / signal / provide / transmit UE capabilities (e.g., capability information) based on or associated with a current state of UE 104, such as a current location (e.g., region) and / or mode (402) and / or traffic conditions of UE 104. For example, UE 104 may determine its current situation / state (e.g., location, mode, and / or traffic conditions) and associate the situation with corresponding capability information. For example, UE 104 may determine the current situation based on a threshold or regulatory requirement indicated by BS 102.

[0039] After providing the UE capabilities (e.g., the first capability information set), the UE 104 may recognize or determine that the situation (e.g., the mode and / or location of the UE 104, and / or the traffic situation) has changed or is relatively close to changing or is about to change. For example, the UE 104 may determine that the mode has changed (e.g., RRC state or motion state) and / or the UE 104 is about to enter or has entered a different area (e.g., exceeds a threshold or boundary) to update the location with or without an additional offset value, e.g., H>=H. x –h_offset. In this example, H may refer to the current altitude of UE 104, H x may refer to the boundary of a region / area associated with the reported first capability information set, and h_offset may refer to the height and / or offset of the region.

[0040] In response to the change in mode, location, and / or traffic conditions, UE 104 may trigger reporting / updating UE capabilities in a second report, e.g., a second capability information set of UE 104. In some cases, the second capability information set may include at least a portion of similar information (e.g., UE capabilities) as the first capability information set (e.g., overlapping information). In some other cases, the second capability information set may include one or more different / changed features / capabilities (e.g., non-overlapping information) from the first capability information set.

[0041] In some implementations, in order to trigger a capability update process (e.g., in response to a mode of UE 104 and / or a location of UE 104, and / or a change in traffic conditions), UE 104 may send an RS to BS 102 (404). The RS may include content with an indicator / signaling / identifier for UE capability change / update. In some cases, UE 104 may not transmit the RS to BS 102. BS 102 may send scheduling information to UE 104 (406). For example, BS 102 may provide scheduling information to provide resources to UE 104 to report its capabilities. Therefore, in response to the change in the situation, UE 104 may report another set of capabilities (e.g., a second capability information set) to BS 102 (408). Compared to the first capability information set, the second capability information set may include one or more updated / modified / changed parameters and / or one or more similar parameters. In some aspects, the second report may include a flag for indicating that the capability information of UE 104 has been updated.

[0042] Example Implementation 2

[0043] Similar to the example implementation 1 discussed above, UE 104 (e.g., an air UE, a mobile phone, and / or other terminal) can connect to a network to communicate with one or more BSs 102 (e.g., gNBs). In response to connecting to the network, UE 104 can report a first UE capability set (e.g., a first capability information set) to at least one of the BSs 102.

[0044] In some arrangements, based on the state / situation or state change (e.g., mode, location, and / or traffic conditions) of the UE 104, the UE 104 may send / transmit / allocate (e.g., additional) information (e.g., sometimes referred to as assistance information) to the network (e.g., BS 102). The assistance information may provide / indicate one or more limitations (e.g., reduction of UE capabilities on multiple-input multiple-output (MIMO), power information, etc.) for communication between the UE 104 and the BS 102 and other devices. For example, based on the state of the UE 104, the UE 104 may send assistance information to limit or apply at least one limitation on the UE capabilities (e.g., limitation on a portion of the first capability information set), thereby reducing the capabilities of the UE 104. Reducing the capabilities of the UE 104 may improve communication between the UE 104 and the BS 102, for example, in lower bandwidth areas / regions (e.g., reducing MIMO), etc. In some cases, reducing the capabilities of the UE 104 may avoid interference with other communications, for example, by reducing the number of beams and / or reducing the maximum transmission power.

[0045] In some arrangements, the first capability information set may include one or more predefined UE capabilities (e.g., a basic portion of UE capabilities). For example, the basic portion of UE capabilities may refer to capability information shared by different modes, locations, and / or traffic conditions, such that changes in the mode of UE 104 and / or the location of UE 104, and / or the traffic conditions do not change these basic portions of UE capabilities. In response to a change in the current state or the state of UE 104 (e.g., mode, location, and / or traffic conditions), UE 104 may send additional information (e.g., assistance information) to BS 102 (e.g., the network) to provide / send some additional / extra features / capabilities in the previously reported first UE capability set (e.g., support for analog beamforming and / or QCL Type D and other features not included). In addition to or in lieu of the additional features / capabilities, the UE 104 may update / modify at least one previous value in a previously reported first UE capability set (e.g., updating supported power, modulation and coding scheme (MCS) and / or MIMO information) for communication between the UE 104 and the BS 102 and other devices of the network. Therefore, the system and method of the technical solution may provide reporting and / or updating of UE capability information in communication after an initial report of UE capabilities.

[0046] Figure 5 A flow chart of a method 500 for reporting UE capabilities is shown. The method 500 may be used in conjunction with the present invention. Figures 1 to 4 In general, method 500 may include reporting a set of capability information (502). Method 500 may include receiving a set of capability information (504).

[0047] In various arrangements, a wireless communication device (e.g., UE) may report / send / transmit / provide / signal / indicate a first set of capability information (e.g., UE capabilities) to a wireless communication node (e.g., BS, gNB, or network node) (502). In response to the report, the wireless communication node may receive / obtain / acquire the first set of capability information from the wireless communication device. The first set of capability information may be associated with the wireless communication device. In response to a connection with a wireless communication node (e.g., other network device or node), the wireless communication device may send the first set of capability information.

[0048] In some arrangements, the first capability information set may include various capability information subsets associated with the wireless communication device. Each capability information subset may correspond to a corresponding mode and / or location and / or traffic condition of the wireless communication device. For example, a first capability information subset may correspond to a first mode and / or a first location, a second capability information subset may correspond to a second mode and / or a second location (e.g., the second mode and / or the second location may be similar to or different from the first mode and / or the first location), etc. The first capability information subset and the second capability information subset may also be associated with similar or different traffic conditions.

[0049] In some arrangements, in response to determining that a current mode and / or location (and / or traffic conditions in some cases) of the wireless communication device has changed or is relatively close to (e.g., about to) change, the wireless communication device may update / modify / change a first set of capability information to a second set of capability information.

[0050] In some implementations, the first capability information set and the second capability information set may overlap. For example, one or more capabilities of the first capability information set may overlap or be the same as one or more capabilities of the second capability information set.

[0051] In some implementations, the first capability information set and the second capability information set may not overlap. For example, at least one capability of the second capability information set may be different from a capability of the first capability information set.

[0052] In some arrangements, the wireless communication device may send auxiliary information (e.g., additional information) to the wireless communication node. The wireless communication device may send the auxiliary information to limit the capabilities of the wireless communication device, for example, based on at least one of a mode of the wireless communication device and / or a location of the wireless communication device, and / or a traffic condition. For example, each mode, location, and / or traffic condition may be associated with a corresponding capability. For example, certain modes, locations, and / or traffic conditions may be associated with reduced capabilities compared to the first capability information set. In this case, the wireless communication may provide at least one limitation on the capabilities of the wireless communication device, for example, as indicated in the first capability information set, to support communication between the wireless communication device and the wireless communication node.

[0053] In some arrangements, the wireless communication device may send auxiliary information to the wireless communication node to report updated capabilities of the wireless communication device that are not included in the first capability information set. For example, in order to enhance communication between the wireless communication device and the wireless communication node based on mode, location and / or traffic conditions, the wireless communication device may transmit additional information (e.g., additional features / capabilities / support) and / or update specific values ​​in the first capability information set. These values ​​may include supported power, MCS and / or MIMO information, etc.

[0054] Although various embodiments of the present solution have been described above, it should be understood that they are given only by way of example and not by way of limitation. Similarly, various figures may depict example architectures or configurations, which are provided to enable those of ordinary skill in the art to understand the exemplary features and functions of the present solution. However, these personnel will understand that the present solution is not limited to the example architectures or configurations shown, but may be implemented using a variety of alternative architectures and configurations. In addition, it will be appreciated by those of ordinary skill in the art that one or more features of an embodiment may be combined with one or more features of another embodiment described herein. Therefore, the breadth and scope of the present disclosure should not be limited by any of the above-described exemplary embodiments.

[0055] It should also be understood that any reference to an element using names such as "first," "second," etc., in this application does not generally limit the number or order of those elements. Rather, these names may be used in this application as a convenient means of distinguishing between two or more elements or instances of an element. Thus, a reference to a first and a second element does not mean that only two elements may be used, or that the first element must be located before the second element in some manner.

[0056] In addition, those of ordinary skill in the art will appreciate that information and signals may be represented using any of a variety of different techniques. For example, data, instructions, commands, information, signals, bits, and symbols that may be referenced in the above description may be represented by voltages, currents, electromagnetic waves, magnetic fields or particles, optical fields or particles, or any combination thereof.

[0057] Those of ordinary skill in the art will further understand that any of the various illustrative logical blocks, modules, processors, devices, circuits, methods, and functions described in conjunction with this application may be implemented by electronic hardware (e.g., digital implementation, analog implementation, or a combination of both), firmware, various forms of programs or design codes containing instructions (for convenience, may be referred to as "software" or "software modules" in this application), or any combination of these technologies. In order to clearly illustrate this interchangeability of hardware, firmware, and software, various illustrative components, blocks, modules, circuits, and steps have been described above generally in terms of their functions. Whether such functionality is implemented as hardware, firmware, or software, or a combination of these technologies, depends on the specific application and the design constraints imposed on the overall system. Technicians may implement the described functionality in various ways for each specific application, but such implementation decisions will not cause a departure from the scope of this disclosure.

[0058] In addition, it will be understood by those skilled in the art that the various illustrative logic blocks, modules, devices, components and circuits described herein may be implemented or performed in an integrated circuit (IC) including a general purpose processor, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic device, or any combination thereof. The logic blocks, modules and circuits may further include antennas and / or transceivers to communicate with various components within a network or within a device. A general purpose processor may be a microprocessor, but alternatively, the processor may be any conventional processor, controller or state machine. The processor may also be implemented as a combination of computing devices, for example, a combination of a DSP and a microprocessor, a plurality of microprocessors, one or more microprocessors combined with a DSP core, or any other suitable configuration to perform the functions described herein.

[0059] If implemented in software, the functions may be stored as one or more instructions or codes on a computer-readable medium. Therefore, the steps of the method or algorithm disclosed in the present application may be implemented as software stored on a computer-readable medium. Computer-readable media include computer storage media and communication media, and communication media include any media that enables a computer program or code to be transferred from one place to another. The storage medium can be any available medium that a computer can access. As an example and not limitation, such computer-readable media may include RAM, ROM, EEPROM, CD-ROM or other optical disk storage, magnetic disk storage or other magnetic storage devices, and any other medium that can be used to store the desired program code in the form of instructions or data structures and can be accessed by a computer.

[0060] In this application, the term "module" used in this application refers to software, firmware, hardware, and any combination of these elements to perform the relevant functions described in this application. In addition, for the purpose of discussion, various modules are described as discrete modules; however, it is obvious to a person of ordinary skill in the art that two or more modules can be combined into a single module to perform the relevant functions according to the implementation of the present solution.

[0061] In addition, memory or other storage and communication components may be used in the implementation of the present solution. It should be understood that, for the sake of clarity, the above description has described the implementation of the present solution with reference to different functional units and processors. However, it will be apparent that any appropriate functional distribution between different functional units, processing logic elements or domains can be used without departing from the present solution. For example, functions illustrated as being performed by separate processing logic elements or controllers can be performed by the same processing logic elements or controllers. Therefore, references to specific functional units are only references to suitable devices for providing the described functions, rather than indicating a strict logical or physical structure or organization.

[0062] Various modifications to the embodiments described in the present disclosure will be apparent to those skilled in the art, and the general principles defined in this application may be applied to other embodiments without departing from the scope of the present disclosure. Therefore, the present disclosure is not intended to be limited to the embodiments shown in this application, but is to be given the widest scope consistent with the novel features and principles disclosed in this application, as described in the claims.
