NETWORK NODE, NODE, AND METHODS PERFORMED BY THE SAME IN A WIRELESS COMMUNICATION SYSTEM

[0001] The present application generally relates to the field of wireless communications, and more specifically, to a network node, a node, and methods performed by the network node and the node.

[0002] 5G mobile communication technologies define broad frequency bands such that high transmission rates and new services are possible, and can be implemented not only in "Sub 6GHz" bands such as 3.5GHz, but also in "Above 6GHz" bands referred to as mmWave including 28GHz and 39GHz. In addition, it has been considered to implement 6G mobile communication technologies (referred to as Beyond 5G systems) in terahertz bands (for example, 95GHz to 3THz bands) in order to accomplish transmission rates fifty times faster than 5G mobile communication technologies and ultra-low latencies one-tenth of 5G mobile communication technologies.

[0003] At the beginning of the development of 5G mobile communication technologies, in order to support services and to satisfy performance requirements in connection with enhanced Mobile BroadBand (eMBB), Ultra Reliable Low Latency Communications (URLLC), and massive Machine-Type Communications (mMTC), there has been ongoing standardization regarding beamforming and massive MIMO for mitigating radio-wave path loss and increasing radio-wave transmission distances in mmWave, supporting numerologies (for example, operating multiple subcarrier spacings) for efficiently utilizing mmWave resources and dynamic operation of slot formats, initial access technologies for supporting multi-beam transmission and broadbands, definition and operation of BWP (BandWidth Part), new channel coding methods such as a LDPC (Low Density Parity Check) code for large amount of data transmission and a polar code for highly reliable transmission of control information, L2 pre-processing, and network slicing for providing a dedicated network specialized to a specific service.

[0004] Currently, there are ongoing discussions regarding improvement and performance enhancement of initial 5G mobile communication technologies in view of services to be supported by 5G mobile communication technologies, and there has been physical layer standardization regarding technologies such as V2X (Vehicle-to-everything) for aiding driving determination by autonomous vehicles based on information regarding positions and states of vehicles transmitted by the vehicles and for enhancing user convenience, NR-U (New Radio Unlicensed) aimed at system operations conforming to various regulation-related requirements in unlicensed bands, NR UE Power Saving, Non-Terrestrial Network (NTN) which is UE-satellite direct communication for providing coverage in an area in which communication with terrestrial networks is unavailable, and positioning.

[0005] Moreover, there has been ongoing standardization in air interface architecture / protocol regarding technologies such as Industrial Internet of Things (IIoT) for supporting new services through interworking and convergence with other industries, IAB (Integrated Access and Backhaul) for providing a node for network service area expansion by supporting a wireless backhaul link and an access link in an integrated manner, mobility enhancement including conditional handover and DAPS (Dual Active Protocol Stack) handover, and two-step random access for simplifying random access procedures (2-step RACH for NR). There also has been ongoing standardization in system architecture / service regarding a 5G baseline architecture (for example, service based architecture or service based interface) for combining Network Functions Virtualization (NFV) and Software-Defined Networking (SDN) technologies, and Mobile Edge Computing (MEC) for receiving services based on UE positions.

[0006] As 5G mobile communication systems are commercialized, connected devices that have been exponentially increasing will be connected to communication networks, and it is accordingly expected that enhanced functions and performances of 5G mobile communication systems and integrated operations of connected devices will be necessary. To this end, new research is scheduled in connection with eXtended Reality (XR) for efficiently supporting AR (Augmented Reality), VR (Virtual Reality), MR (Mixed Reality) and the like, 5G performance improvement and complexity reduction by utilizing Artificial Intelligence (AI) and Machine Learning (ML), AI service support, metaverse service support, and drone communication.

[0007] Furthermore, such development of 5G mobile communication systems will serve as a basis for developing not only new waveforms for providing coverage in terahertz bands of 6G mobile communication technologies, multi-antenna transmission technologies such as Full Dimensional MIMO (FD-MIMO), array antennas and large-scale antennas, metamaterial-based lenses and antennas for improving coverage of terahertz band signals, high-dimensional space multiplexing technology using OAM (Orbital Angular Momentum), and RIS (Reconfigurable Intelligent Surface), but also full-duplex technology for increasing frequency efficiency of 6G mobile communication technologies and improving system networks, AI-based communication technology for implementing system optimization by utilizing satellites and AI (Artificial Intelligence) from the design stage and internalizing end-to-end AI support functions, and next-generation distributed computing technology for implementing services at levels of complexity exceeding the limit of UE operation capability by utilizing ultra-high-performance communication and computing resources.

[0105] a third node: a base station, wherein in an example, the base station is a node that directly transmits data with the first node, for example, the base station is a reader (e.g., a reader for an AIoT device); and in another example, the base station transmits data with the first node via the second node, i.e., the second node is a reader for the first node; in the present invention, the third node may also be referred to as a third device, but the following description still uses the "the third node";

[0106] a fourth node: a network device, wherein in an example, the device is a device of a core network, such as an access and mobility management function (AMF), a mobility management entity (MME); and in another example, the device is another network entity that can communicate directly or indirectly with the third node;

[0107] a fifth node: a base station, which is distinguished from the base station of the third node, wherein in an example, the base station is a node that transmits data directly with the first node, for example, the base station is a reader (e.g., a reader for an AIoT device), and in another example, the base station transmits data with the first node via other nodes (e.g., the second node), i.e., the other nodes are the reader for the first node.

[0108] The base station involved in the above third and fifth nodes may be one of the following types (other types of devices that can be used for user terminal access are not excluded):

[0109] * a long-term evolution (LTE) base station;

[0110] * a 5G base station;

[0111] * a 6G base station;

[0112] * a RAN node;

[0113] * a non-terrestrial network (NTN) base station;

[0114] * a high altitude platform station (HAPS) base station;

[0115] * a Drone base station; and

[0116] * a WIFI access point.

[0117] Ambient / passive IoT devices have low complexity and low or no energy storage capacity, so such devices cannot access and communicate with conventional base station devices like ordinary user terminals (terminals with higher processing power and energy storage capacity). In order to complete the management and data reading and writing of the ambient / passive IoT devices, network access and / or data transmission of the ambient / passive IoT devices can be carried out in the following two methods:

[0118] * Method 1: the base station manages the ambient / passive IoT devices directly or transmits data directly with the ambient / passive IoT devices; and

[0119] * Method 2: the base station manages the ambient / passive IoT devices or transmits data to the ambient / passive IoT devices through other UEs (e.g., the second node as described above).

[0120] In the above two methods, devices of ambient / passive IoT need to occupy certain wireless resources for network access or data transmission. Considering the particularity　of ambient / passive IoT devices (e.g., low complexity, low or no energy storage capacity, etc. as described above), how to allocate resources to the ambient / passive IoT devices is a problem to be solved urgently. In the present invention, the following description is set forth with the ambient / passive IoT as an example, but the method below is also applicable to other types of devices (e.g., a cell phone terminal, an IoT device, etc.), and in an example, if "the ambient / passive IoT device" or "the first node" or "the second node" in the description below is replaced with other types of devices, the method described below is also applicable.

[0121] In order to solve the above problem of resource allocations, the following elements will be comprised in the solutions designed by the present invention:

[0122] * a procedure or process: devices of ambient / passive IoT (e.g., the first node, the second node, or the third node as described above) will perform some different types of procedures or processes. The procedures in present invention may comprise at least one of: a data transmission procedure, an inventory procedure, a command procedure, an inventory+command procedure, or a random access procedure. However, the content in the present invention may also be applicable to other types of procedures. Further, procedures of the same type may also comprise many types of different procedures, such as inventory procedure 1, inventory procedure 2, etc., and these distinctions may be made by the fact that these procedures of the same type accomplish different tasks, or involve different UEs, or use different resources, and so forth. In order to distinguish these different types of procedures, they may be indicated by different identity information, as well as by different type indication information, and for different procedures within procedures of the same type, they may also be distinguished by different identity information. In the present invention, identity information for procedures (e.g., procedure ID, process ID and session ID) may be used to distinguish different types of procedures, or to distinguish different procedures within procedures of the same type. In addition, in the process of executing a procedure, data transmission occurs among nodes, and therefore, in the present invention, the "data transmission" is equivalent to "the procedure".

[0123] * an "accessing opportunity" or "accessing occasion": denotes a resource in a time domain or a frequency domain, wherein the length of the resource in the time domain may be fixed or not, or the length of the resource in the frequency domain may be fixed or not. For the sake of convenience, the present invention refers to this as the "accessing opportunity" or "accessing occasion", but also does not exclude the use of other names. Within resources indicated by the accessing occasion, the second node may complete a procedure (e.g., a data transmission procedure, a random access procedure, an inventory procedure, a command procedure, a reading operation procedure, a writing operation procedure, a disabling procedure, etc.) with one or more first nodes. In an example, the accessing occasion may be the smallest unit of resource allocations.

[0124] In order to solve the above problem of resource allocations, in the above method 1, the resource allocations may be performed by the base station, and in the above method 2, the resource allocations may be performed by the base station, for example, the base station allocates resources to other UEs, which use the allocated resources to communicate with the ambient / passive IoT devices, or the base station may also allocate a resource pool to other UEs, which allocate resources in the resource pool to the ambient / passive IoT devices. In the above method of resource allocations, the base station needs to decide the allocated resources, and the present invention proposes a method of allocating resources for communication of the ambient / passive IoT devices by the base station, which comprises the following signaling procedure for resource allocations, as shown in FIG. 2.

The allocated resources are used for data transmission, or for the third node or the second node to perform related procedures with the first node. In an example, the data transmission or related procedures is / are performed by the first node, and in another example, the data transmission or related procedures is / are performed by the second node (e.g., performed between the second node and the ambient / passive IoT devices).

[0326] ***** end time information indicating an ending time of the released (or terminated) resources;

[0327] ***** start frequency point information indicating information about a start position of the released (or terminated) resources in the frequency domain;

[0328] ***** end frequency point information indicating information about an end position of the released (or terminated) resources in a frequency domain;

[0329] ***** time-frequency resource information indicating time-domain and frequency-domain information of the released (or terminated) resources, wherein in an example, the information indicates time-frequency resources within a cycle, and in another example, the information indicates time-frequency resources of all the released (or terminated) resources, the information comprising at least one of:

[0330] ****** time-domain resource range information, e.g., a slot index / identity, a subframe index / identity, a symbol index / identity, an accessing occasion index / identity, etc., wherein the above indexes or identities may indicate a start position and / or a termination position;

[0331] ****** frequency-domain resource range information, e.g., a resource block index / identity, a subcarrier index / identity, a bandwidth part index / identity, wherein the above indexes or identities may indicate a start position and / or a termination position;

[0332] ****** resource size indication information indicating a size of the released (or terminated) resources, e.g., a length of the time-domain range, a length of the frequency-domain range, a number of accessing occasions, and the like.

[0333] Based on the above step 1-0, an implementation of a procedure for requesting resources may be as follows.

[0334] Step 1-0: the third node transmits a first configuration message to the second device;

[0335] Step 1-1: the second device transmits a first request message to the third node, the function of the message is to request resources, and the transmission of the message or the content of information comprised in the message may be determined according to the first configuration message in the above step. In an implementation, if the first request message is transmitted by a physical signal, different configurations of the physical signal are selected to transmit the physical signal according to different types of requests, that is, different resources are requested using different configurations of the physical signal; and if the first request message is transmitted by a MAC layer signaling, information carrying different logical channels or logical channel groups is selected to be transmitted according to different types of requests, that is, the different logical channels or logical channel groups are used to indicate different resource requests;

[0336] Step 1-2: the third node transmits a first resource configuration message to the second device.

[0337] In the above procedure, when the first node or the second node transmits a resource request to the third node, the third node may reject the request. In the above procedure, in the step 1-2, the third node may reject the resource request of the first node or the second node through the first resource configuration message, such as the above "second resource rejection information". In another example, the first node or the second node may decide on its own whether its resource request is rejected, as shown in the following procedure.

[0338] Step 2-1: the first node or the second node transmits a first request message to the third node, the message is used to request resources, and the specific description of the message may refer to the description in the above step 1-1. In a preferred example, the first node or the second node may request resources by transmitting a physical signal, and in another preferred example, the first node or the second node may request resources by transmitting a MAC CE;

[0339] Step 2-2: the first node or the second node determines whether the resource request is accepted. Specifically:

[0340] * If the first node or the second node receives the first resource configuration message in the above step 1-2, and the message comprises the allocated resources, the first node or the second node may determine that the resource request is accepted;

[0341] * If the first node or the second node receives the first resource configuration message comprising the "second resource rejection information", the first node or the second node determines the rejected resource request based on the information;

[0342] * If the first node or the second node does not receive the allocated resources, the first node or the second node may determine whether the resource request is rejected or whether the resource request is satisfied based on one of the following methods.

[0343] ** Method 1: a timer, wherein after the first node or the second node transmits the first request message, the first node or the second node starts the timer, and if the allocated resources are not received before the timer expired, it is considered that the resource request is rejected, and if the allocated resources do not complete the required data transmission, or if the allocated resources do not complete the corresponding procedure (for example, the procedure is not completed within a specified time), it is considered that the resource request has not been satisfied. In an example, the timer may be named as a resource request failure timer. The timer may be restarted, for example, when the third node allocates the requested resources, or when the resource request is satisfied, the first node or the second node restarts the timer;

[0344] ** Method 2: a counter, wherein after the first node or the second node transmits the first request message, the first node or the second node updates the counter, and if the allocated resources have not been received by the time the counter reaches a certain number, it is considered that the resource request is rejected, and if the allocated resources do not complete the required data transmission by the time the counter reaches a certain number, or if the allocated resources do not complete the corresponding procedure (for example, the procedure is not completed within the specified time), it is considered that the resource request has not been satisfied. In an example, the counter may be named as a resource request failure counter. The counter may be restarted, for example, when the third node allocates the requested resources, or when the resource request is satisfied, the first node or the second node restarts the counter.

[0345] A beneficial effect of the above procedure is to help the first node or the second node to know the resource allocation status of the third node timely, thereby determining whether to perform the AIoT procedure, and reducing unnecessary resource wastes.

[0346] When the first node or the second node occurs a handover or failure, the first node or the second node needs to perform a data transmission or procedure in a new accessed base station. During the handover or after the failure, the first node or the second node may determine at least one of the following behaviors according to the user configuration information comprised in the first configuration message in the above step 1-0.

[0347] There are at least one of the following behaviors.

[0348] * Behavior 1: suspending behavior, that is, determining suspended data, or suspended resources, or suspended procedures based on the "suspend-related information", wherein optionally, a timer (such as a timer configured by the suspended timer configuration information) will be started, and when the timer expired, the suspended data is released, the suspended procedure is terminated, and the suspended resources are released;

[0349] * Behavior 2: releasing behavior, that is, releasing the suspended data, terminating the suspended process, and releasing the suspended resources according to the "release-related information", wherein a timer (such as a timer configured by the release (or termination) timer configuration information) will be started, and when the timer expired, the suspended data is released, the suspended procedure is terminated, and the suspended resources are released;

[0350] * Behavior 3: saving the information received from the core network, such as the information in the first request message, and optionally starting a timer, and releasing the information received from the core network when the timer expired;

[0351] * Behavior 4: retaining the data that needs to be written to the AIoT device, and optionally, starting a timer, and releasing the data that needs to be written to the AIoT device when the timer expired;

[0352] Behavior 5: retaining the data read from the AIoT device, and optionally starting a timer, and releasing the data read from the AIoT device when the timer expired;

[0353] Behavior 6: retaining data that needs to be transmitted in the AIoT air interface, and optionally, starting a timer, and releasing the data that needs to be transmitted over the AIoT air interface when the timer expired;

[0354] Behavior 7: releasing (or terminating) the data transmitted over the AIoT air interface or the AIoT procedure or the AIoT resources, and flushing the AIoT data.

[0355] A beneficial effect of the above behaviors is to help the first node or the second node to retain completed data transmission or procedures, thereby reducing repeated data transmission or repeated procedure execution, and saving spectrum resources.

[0356] When the first node or the second node occurs a handover or failure, after the first node or the second node accesses a new base station, if there is data related to AIoT that needs to be transmitted to the core network at the first node or the second node, the first node or the second node may transmit a second request message to the third node, and an example of the request message is the above first request message, and further, in order to indicate that the data related to AIoT is present at the first node or the second node, the second request message may further comprise at least one of:

[0357] * AIoT data present indication information indicating the presence of data or signaling related to AIoT that is not transmitted at the first node or the second node, and these data or signaling may be transmitted to the core network, may be transmitted to the third node, may be transmitted to the first node by the second node, or may be transmitted to the second node by the first node; or

[0358] * data feature information indicating features of existing data, wherein in an example, the data feature information may refer to the "first feature information" in the above step 1-1.

[0359] A beneficial effect of the above procedure is to help the network side to know the storage status of AIoT data at the first node or the second node, transmit the data timely, and ensure the service quality of the AIoT procedure.
