[0047] 1. Mobile Communication Technology and Environment
[0048] FIG. 1 illustrates an example wireless communication network, and / or system, 100 in which techniques disclosed herein may be implemented, in accordance with an embodiment of the present disclosure. 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 herein referred to as “network 100. ” Such an example network 100 includes a base station 102 (hereinafter “BS 102” ; also referred to as wireless communication node) and a user equipment device 104 (hereinafter “UE 104” ; also referred to as wireless communication device) that can 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 overlaying a geographical area 101. In FIG. 1, the BS 102 and UE 104 are contained within a respective geographic boundary of cell 126. Each of the other cells 130, 132, 134, 136, 138 and 140 may include at least one base station operating at its allocated bandwidth to provide adequate radio coverage to its intended users.
[0049] For example, the BS 102 may operate at an allocated channel transmission bandwidth to provide adequate coverage to the UE 104. The BS 102 and the UE 104 may communicate via a downlink radio frame 118, and an uplink radio frame 124 respectively. Each radio frame 118 / 124 may be further divided into sub-frames 120 / 127 which may include data symbols 122 / 128. In the present disclosure, the BS 102 and UE 104 are described herein as non-limiting examples of “communication nodes, ” generally, which can practice the methods disclosed herein. Such communication nodes may be capable of wireless and / or wired communications, in accordance with various embodiments of the present solution.
[0050] FIG. 2 illustrates a block diagram of an example wireless communication system 200 for transmitting and receiving wireless communication signals (e.g., OFDM / OFDMA signals) in accordance with some embodiments of the present solution. 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, system 200 can be used to communicate (e.g., transmit and receive) data symbols in a wireless communication environment such as the wireless communication environment 100 of FIG. 1, as described above.
[0051] System 200 generally includes a base station 202 (hereinafter “BS 202” ) and a user equipment device 204 (hereinafter “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 module being coupled and interconnected with one another as necessary via a data communication bus 220. 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 module being coupled and interconnected with one another as necessary via a data communication bus 240. The BS 202 communicates with the UE 204 via a communication channel 250, which can be any wireless channel or other medium suitable for transmission of data as described herein.
[0052] As would be understood by persons of ordinary skill in the art, system 200 may further include any number of modules other than the modules shown in FIG. 2. Those skilled in the art will understand that the various illustrative blocks, modules, circuits, and processing logic described in connection with the embodiments disclosed herein may be implemented in hardware, computer-readable software, firmware, or any practical combination thereof. To clearly illustrate this interchangeability and compatibility of hardware, firmware, and software, various illustrative components, blocks, modules, circuits, and steps are described generally in terms of their functionality. Whether such functionality is implemented as hardware, firmware, or software can depend upon the particular application and design constraints imposed on the overall system. Those familiar with the concepts described herein may implement such functionality in a suitable manner for each particular application, but such implementation decisions should not be interpreted as limiting the scope of the present disclosure.
[0053] In accordance with some embodiments, the UE transceiver 230 may be referred to herein as an “uplink” transceiver 230 that includes a radio frequency (RF) transmitter and a RF receiver each comprising circuitry that is coupled to the antenna 232. A duplex switch (not shown) may alternatively couple the uplink transmitter or receiver to the uplink antenna in time duplex fashion. Similarly, in accordance with some embodiments, the BS transceiver 210 may be referred to herein as a “downlink” transceiver 210 that includes a RF transmitter and a RF receiver each comprising circuity that is coupled to the antenna 212. A downlink duplex switch may alternatively couple the downlink transmitter or receiver to the downlink antenna 212 in time duplex fashion. The operations of the two transceiver modules 210 and 230 may be coordinated in time such that the uplink receiver circuitry is coupled to the uplink antenna 232 for reception of transmissions over the wireless transmission link 250 at the same time that the downlink transmitter is coupled to the downlink antenna 212. Conversely, the operations of the two transceivers 210 and 230 may be coordinated in time such that the downlink receiver is coupled to the downlink antenna 212 for reception of transmissions over the wireless transmission link 250 at the same time that the uplink transmitter is coupled to the uplink antenna 232. In some embodiments, there is close time synchronization with a minimal guard time between changes in duplex direction.
[0054] The UE transceiver 230 and the base station transceiver 210 are configured to communicate via the wireless data communication link 250, and cooperate with a suitably configured RF antenna arrangement 212 / 232 that can support a particular 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 the Long Term Evolution (LTE) and emerging 5G standards, and the like. It is understood, however, that the present disclosure is not necessarily limited in application to a particular standard and associated protocols. Rather, the UE transceiver 230 and the base station transceiver 210 may be configured to support alternate, or additional, wireless data communication protocols, including future standards or variations thereof.
[0055] In accordance with various embodiments, the BS 202 may be an evolved node B (eNB) , a serving eNB, a target eNB, a femto station, or a pico station, for example. In some embodiments, the UE 204 may be embodied in various types of user devices such as a mobile phone, a smart phone, a personal digital assistant (PDA) , tablet, laptop computer, wearable computing device, etc. The processor modules 214 and 236 may be implemented, or realized, with 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, designed to perform the functions described herein. In this manner, a processor may be realized as a microprocessor, a controller, a microcontroller, a state machine, or the like. A processor may also be implemented as a combination of computing devices, e.g., a combination of a digital signal processor and a microprocessor, a plurality of microprocessors, one or multiple microprocessors in conjunction with a digital signal processor core, or any other such configuration.
[0056] Furthermore, the steps of a method or algorithm described in connection with the embodiments disclosed herein may be embodied directly in hardware, in firmware, in a software module executed by processor modules 214 and 236, respectively, or in any practical combination thereof. The memory modules 216 and 234 may be realized as RAM memory, flash memory, ROM memory, EPROM memory, EEPROM memory, registers, a hard disk, a removable disk, a CD-ROM, or any other form of storage medium known in the art. In this regard, memory modules 216 and 234 may be coupled to the processor modules 210 and 230, respectively, such that the processors modules 210 and 230 can read information from, and write information to, memory modules 216 and 234, respectively. The memory modules 216 and 234 may also be integrated into their respective processor modules 210 and 230. In some embodiments, the memory modules 216 and 234 may each include a cache memory for storing temporary variables or other intermediate information during execution of instructions to be 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 the processor modules 210 and 230, respectively.
[0057] The network communication module 218 generally represents the hardware, software, firmware, processing logic, and / or other components of the base station 202 that enable bi-directional communication between base station transceiver 210 and other network components and communication nodes configured to communicate with the base station 202. For example, network communication module 218 may be configured to support internet or WiMAX traffic. In a typical deployment, without limitation, network communication module 218 provides an 802.3 Ethernet interface such that base station transceiver 210 can communicate with a conventional Ethernet based computer network. In this manner, the network communication module 218 may include a physical interface for connection to the computer network (e.g., Mobile Switching Center (MSC) ) . The terms “configured for, ” “configured to” and conjugations thereof, as used herein with respect to a specified operation or function, refer to a device, component, circuit, structure, machine, signal, etc., that is physically constructed, programmed, formatted and / or arranged to perform the specified operation or function.
[0058] The Open Systems Interconnection (OSI) Model (referred to herein as, “open system interconnection model” ) is a conceptual and logical layout that defines network communication used by systems (e.g., wireless communication device, wireless communication node) open to interconnection and communication with other systems. The model is broken into seven subcomponents, or layers, each of which represents a conceptual collection of services provided to the layers above and below it. The OSI Model also defines a logical network and effectively describes computer packet transfer by using different layer protocols. The OSI Model may also be referred to as the seven-layer OSI Model or the seven-layer model. In some embodiments, a first layer may be a physical layer. In some embodiments, a second layer may be a Medium Access Control (MAC) layer. In some embodiments, a third layer may be a Radio Link Control (RLC) layer. In some embodiments, a fourth layer may be a Packet Data Convergence Protocol (PDCP) layer. In some embodiments, a fifth layer may be a Radio Resource Control (RRC) layer. In some embodiments, a sixth layer may be a Non Access Stratum (NAS) layer or an Internet Protocol (IP) layer, and the seventh layer being the other layer.

[0060] 2. Systems and Methods for Task-driven Cooperative Intelligence Cluster Management
[0061] Industry standards (e.g., 3GPP standards) for group communications (e.g., in the 5G Core Network) focus on forming a collection of devices to operate, such as a collection of smart home equipment or wearables, as shown in FIG. 3. However, in certain systems (e.g., 5G-A and / or 6G) , when applications involve various automated devices, there can be a significant challenge in enabling intelligent cooperative operations within such a workgroup. Addressing this challenge may require overcoming several technical hurdles, such as dynamic cluster configuration, adaptive task-driven traffic management, or task-level QoS management, among others.
[0062] As shown in FIG. 4, inspection tasks can vary depending on the task complexity, inspected product line, or manufacturing environment (e.g., lighting, noise, temperature, etc. ) of a smart factory. Therefore, a single device may not be sufficient to guarantee efficient operations and provide real-time warnings. For instance, machine arms may have mobility but may have blind spots that they cannot inspect. As a result, the inspection task is to be cooperatively accomplished by machine arms together with high-definition cameras and sensors (e.g., gas sensors, temperature sensors, etc. ) . In such cases, a task-driven cooperative intelligent cluster (CIC) service, which can include different types of devices (e.g., UAVs, autonomous vehicles, robots, sensors, etc. ) controllable by a network, can support the accomplishment of tasks through intelligent collaboration among multiple nodes.
[0063] In a common CIC, there are (or can be) two roles: head and member. The head can be responsible for intra-CIC management, such as adding, modifying, or removing members; splitting tasks among the members; and allocating resources to the related members. The member can be responsible for following the commands from the head and processing the tasks it receives. The head may also allocate tasks to itself if available. The head may act as a control and command entity in the CIC, while the member may act as a working entity. The initial head for a CIC can be configured by the manufacturer, operator, or CIC owner. In certain configurations, the initial head can also be randomly selected by the core network (CN) or gNodeB (gNB) inside one or multiple CIC entities with head capability before / during the task allocation phase or CIC forming phase. In certain configurations, the initial head can be selected if an entity is the first to access the CIC with head capability.
[0064] In certain embodiments, for CN based CIC head selection, CN can fully decide / determine the head (or heads) of a CIC, as shown in FIG. 5. The head selection may be performed with or without CIC related PDU sessions. Without any CIC related PDU sessions, the head selection may be proceeded by using a newly introduced NGAP message or an existing NGAP UE context related message (e.g., initial context setup procedure, UE context modification procedure, etc. ) . The head selection may also not be performed until CIC related task is received by CN and CIC related PDU session may be setup / modified. CN may perform the head selection by using either a newly introduced NGAP message or an existing NGAP PDU related message (e.g., PDU session resource setup procedure, PDU session resource modify procedure, etc. ) .
[0065] For each related CIC (s) , CN may opt / prefer to configure the CIC head. The AMF can send NGAP message A to the NG-RAN node. For each involved CIC (s) , the NG-RAN node may be informed of at least one of the following information: CIC ID, which can be used to identify which CIC can be configured as a CIC head; UE ID, which can be used to identify a UE; CIC head indicator, which can be used to indicate that the aforementioned / particular UE is the head of this CIC; or CIC head information, which can include at least one UE ID indicating the CIC head (when one CIC has one or multiple heads) . NG-RAN node can receive the CIC head information and send the CIC head information to UE via RRC message A. In certain configurations, new RRC message or an existing one (e.g., RRC reconfiguration) may be used. The NG-RAN node may be informed of at least one of the following information: CIC ID, which can be used to identify which CIC can be configured as a CIC head; UE ID, which can be used to identify a UE; CIC head indicator, which can be used to indicate that the aforementioned / particular UE is the head of this CIC; or CIC head information, which can include at least one UE ID (s) indicating the CIC head (when one CIC has one or multiple heads) . The UE may receive the CIC head configuration and know / determine that the UE is the head of the relevant CIC (s) . The UE may then reply with / transmit RRC message B to NG-RAN node including the ACK information. The NG-RAN node may receive RRC message B and send / transmit NGAP message B to the AMF with / including the ACK information.
[0066] In certain embodiments, for CN assisted CIC head selection, CN may not directly select a head for a CIC, as shown in FIG. 6. CN may provide criteria on how to select a CIC head for the NG-RAN node. Based on the received criteria, the NG-RAN node can select a head for the related CIC and notify CN of its decision. The AMF may provide the CIC head criteria to the NG-RAN node for each involved CIC (s) via NGAP message A. In certain configurations, NGAP message A may be a newly defined message or an existing one (e.g., NG setup request, AMF configuration update, etc. ) . For each involved CIC (s) , at least one of the following information may be informed / included: CIC ID information, which can be used to identify which CIC (s) can be configured as a head criteria; or CIC head criteria information, which can be the criteria on how to select a CIC head for CIC (with the above CIC ID (s) ) . An entity can select a CIC head by using at least one of the following information, for example: whether the aforementioned / particular head candidate has CIC head capability; the total and / or remaining and / or occupied hashrate of the head candidate may be higher or may not be lower than a level / value; the current battery / power status of the head candidate is at least a certain a level / value / ratio; the total battery / power status of the head candidate is at least a certain level / value; the restriction on mobility capability and status, including factors such as fly capability, whether the head candidate is flying, crawler capability, or the current speed of the head candidate, among others; the location restriction of the candidate (e.g., the head candidate can only be selected in limited cells or limited areas / locations) ; the other status of the head candidate (e.g., the regulation of the temperature, pressure, humidity, etc. ) ; the threshold of the real-time measured RSRP, RSRQ, or SINR; or the CIC head value / level is at least a certain value / level.
[0067] The CIC head value / level can be a comprehensive evaluation of each candidate head in a CIC. The evaluation of the value / level may consider multiple criteria for each head candidate. To avoid complex configuration, the CN may configure the CIC head value / level for the NG-RAN node as the criteria.

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 functionality. Whether such functionality is implemented as hardware, firmware or software, or a combination of these techniques, depends upon the particular application and design constraints imposed on the overall system. Skilled artisans can implement the described functionality in various ways for each particular application, but such implementation decisions do not cause a departure from the scope of the present disclosure.
[0115] Furthermore, a person of ordinary skill in the art would understand that various illustrative logical blocks, modules, devices, components, and circuits described herein can be implemented within or performed by an integrated circuit (IC) that can include 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 logical blocks, modules, and circuits can further include antennas and / or transceivers to communicate with various components within the network or within the device. A general purpose processor can be a microprocessor, but in the alternative, the processor can be any conventional processor, controller, or state machine. A processor can also be implemented as a combination of computing devices, e.g., a combination of a DSP and a microprocessor, a plurality of microprocessors, one or multiple microprocessors in conjunction with a DSP core, or any other suitable configuration to perform the functions described herein.
[0116] If implemented in software, the functions can be stored as one or multiple instructions or code on a computer-readable medium.

[0117] In this document, the term “module” as used herein, refers to software, firmware, hardware, and any combination of these elements for performing the associated functions described herein. Additionally, for purpose of discussion, the various modules are described as discrete modules; however, as would be apparent to one of ordinary skill in the art, two or more modules may be combined to form a single module that performs the associated functions according to embodiments of the present solution.
[0118] Additionally, memory or other storage, as well as communication components, may be employed in embodiments of the present solution. It will be appreciated that, for clarity purposes, the above description has described embodiments of the present solution with reference to different functional units and processors. However, it will be apparent that any suitable distribution of functionality between different functional units, processing logic elements or domains may be used without detracting from the present solution. For example, functionality illustrated to be performed by separate processing logic elements, or controllers, may be performed by the same processing logic element, or controller. Hence, references to specific functional units are only references to a suitable means for providing the described functionality, rather than indicative of a strict logical or physical structure or organization.
[0119] Various modifications to the embodiments described in this disclosure will be readily apparent to those skilled in the art, and the general principles defined herein can be applied to other embodiments without departing from the scope of this disclosure. Thus, the disclosure is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the novel features and principles disclosed herein, as recited in the claims below.
