The method includes transmitting, by a relay wireless communication terminal, IoT information in an Internet of Things (IoT) wireless communication terminal to a wireless communication node, where the relay wireless communication terminal has a capability to control the IoT wireless communication terminal.

Description

[0001] This document relates generally to wireless communications and, more particularly, to fifth generation (5 th generation, 5G) communications or sixth generation (6 th generation, 6G) communications.

[0002] In recent years, the Internet of Things (IoT), based on narrowband IoT (NB-IoT) and enhanced Machine Type Communication (eMTC) technologies, has been widely deployed or tested in various applications, including smart grids, smart parking, smart transportation and logistics, and smart energy management systems. These applications span multiple vertical sectors, including smart cities and smart homes. This has rapidly driven the upgrading and transformation of traditional industries. For example, smart parking systems can meet the deep coverage requirements of underground scenarios and, based on a variety of sensor types, enable various functions such as parking space search, parking lot monitoring, and area information display. In smart grid systems, functions such as smart meter reading and automatic fault reporting can be implemented. IoT systems based on eMTC technology can achieve vehicle and item tracking and are applicable to the transportation and logistics industries, shared bicycles, and other industries.

[0003] The large-scale application of IoT technology will drive more diversified market and technological demands, and new IoT applications will continue to emerge. It is foreseeable that more sensors, IoT devices, or other types of modules will penetrate various traditional and emerging industries, such as agriculture, industry, environmental protection, urban management, and human health. For example, in a smart library, all books may be equipped with electronic tags, and their movement throughout the library can be fully tracked through real-time book search, location, and quantity or status statistics. The warehousing and logistics industries may already be highly automated, where administrators can use tags based on RFID (Radio Frequency Identification) technology to record, query, and track electronic items. However, the workload remains enormous, as specialized equipment is required to read each tag individually. People are looking forward to more intelligent operations. Due to economic constraints, traditional agriculture may not yet modernize as expected, but it will become more modern and intelligent in the future. Various sensors can be used to monitor crop growing conditions (such as soil, moisture, light, fertility, pests and diseases, etc.) and crop growth in real time. The monitoring data can be used to drive small controllers to adjust growing conditions in real time and respond to disasters in a timely manner. Some potential applications may involve advanced wearable devices or medical equipment, including patches that can be attached to teeth to monitor oral health or diet, and microrobots that can enter blood vessels to treat diseases. Overall, these applications will have significantly different requirements from existing IoT applications. For example, the number of such devices will be enormous, and many will be very small, requiring extremely simple hardware structures and even being unable to integrate batteries. Furthermore, even if these devices can integrate batteries, it may be difficult to ensure long-term battery life due to the diversity of business models. However, due to the large number of these devices, charging or replacing their batteries will become very difficult, requiring significant human and material resources, and may even be impossible.

[0093] Aspect 1 (Architecture 1) :

[0096] In some embodiments, if the IoT UE's Layer 2 PDU or Layer 3 PDU carries information such as control information regarding conflict resolution, the relay UE can disassemble the Layer 2 PDU or Layer 3 PDU to obtain the information and thereby control the IoT UE. The relay UE can also generate a specific message (e.g., for controlling the IoT UE) and assemble the message into a Layer 2 PDU or Layer 3 PDU to be transmitted to the IoT UE. In other words, the relay UE can have Layer 2 or Layer 3 functionality.

[0097] In some embodiments, the IoT Uu stack (eg, including IoT Uu Layer 1 and Layer 2) is located between the IoT UE and the relay UE (see Figure 4 ).

[0098] In some embodiments, the IoT Uu stack (eg, including IoT Uu Layer 1, Layer 2, and Layer 3) is located between the IoT UE and the relay UE (see Figure 5 ).

If the relay UE obtains some information or data packets to be sent to the node or core network, the relay UE can generate an RRC (Radio Resource Control) message that carries the information or data packet. The RRC message can be UL Information Transfer, UE information or other messages. The relay UE processes the RRC message through the PDCP (Packet Data Convergence) protocol entity (also known as PDCP), RLC (Radio Link Control) protocol entity (also known as RLC), MAC (Media Access Control) protocol entity (also known as MAC) and PHY (Physical Layer) protocol entity (also known as PHY), and transmits the RRC message to the node.

The relay UE can also generate a specific message (e.g., for controlling the IoT UE) and assemble the message into a Layer 2 PDU or Layer 3 PDU to be transmitted to the IoT UE. In other words, the relay UE can have Layer 2 or Layer 3 functionality.

In some embodiments, the IoT Uu layer 1, layer 2, and layer 3 (optional) of the IoT UE are used to parse (one or more) PDUs received from the relay UE, node, and / or CN.

[0116] In some embodiments, for the relay UE, the (one or more) PDUs from the IoT UE can be parsed, and the information in the PDU can be obtained through the IoT Uu layer 1, layer 2 and layer 3 (optional) of the relay UE. If the relay UE obtains some information or data packets to be sent to the node or core network, the relay UE can transmit this information or data packets to the node through the data radio bearer (DRB). The node can transmit this information or data packets to the CN through a PDU session or a QoS (quality of service) flow. In some embodiments, the relay UE can also receive some information or data packets through the DRB. The node can receive this information or data packets from the CN through a PDU session or a QoS flow.
