Description

Technical Field

[0001] This application relates to a method and apparatus in a wireless communication system, and particularly to a solution and apparatus related to determining the presence of AIoT devices in the vicinity based on the non - support of cell - configured AIoT functions in a wireless communication system. Background Art

[0002] In recent years, IoT (Internet of Things) has received much attention in the field of wireless communication. Hundreds of billions or even trillions of IoT devices can improve production efficiency and enhance the comfort of life. Most existing wireless communication devices require manual battery replacement or charging, which leads to high maintenance costs and even potential safety hazards in some scenarios (such as wireless sensors in the power and oil industries). Nowadays, the automation and digitization in all walks of life have opened up many new markets. For example, most industries use barcode and RFID (Radio Frequency Identification) technologies to complete asset identification. However, it is difficult for RFID - enabled readers to achieve seamless coverage in densely - deployed scenarios. Therefore, new IoT technologies are needed to support battery - less devices without energy storage capabilities or energy - storage devices that do not require manual replacement or charging.

[0003] 3GPP (3rd Generation Partnership Project) R (Release) 18 began to study AIoT (Ambient Internet of Things). The implementation of this system relies on ultra - low - complexity devices and ultra - low - power technologies. These ultra - low - complexity devices are called AIoT devices. An AIoT device is an IoT device powered by energy harvesting, either battery - less or with limited energy - storage capabilities (e.g., using capacitors). In an AIoT system, the Reader function can be deployed in a UE (User Equipment), mainly responsible for discovering nearby AIoT devices and performing operations on them related to AIoT - related commands (e.g., reading / writing data, etc.). Based on the research progress of R19, the Reader can, according to the instructions of the node controlling the AIoT function (e.g., a core network element supporting the AIoT function), achieve data interaction with nearby AIoT devices through a wireless connection with the AIoT devices. Summary of the Invention

[0004] The applicant has found through research that when the AIoT function is introduced, the UE with the Reader function needs to consider the support of the RAN node for configuring the AIoT function to determine whether there is an AIoT device nearby. Otherwise, it may not be possible to ensure the continuity and reliability of the AIoT services provided by the Reader.

[0005] In view of the above problems, the present application discloses a solution. It should be noted that although the original intention of the present application is for the Uu interface, the present application can also be used for the interface between the Reader and the access network device to achieve similar technical effects as the Uu interface; although the original intention of the present application is for the N1 interface, the present application can also be used for the interface between the Reader and the node controlling the AIoT function to achieve similar technical effects as the N1 interface; although the original intention of the present application is for the NG interface, the present application can also be used for the interface between the access network device and the node controlling the AIoT function to achieve similar technical effects as the NG interface. In addition, adopting a unified solution in different scenarios helps to reduce the hardware complexity and cost.

Layer 1 (L1 layer) is the lowest layer and implements various PHY (Physical layer) signal processing functions. Layer 1 will be referred to as PHY301 in this article. Layer 2 (L2 layer) 305 is above PHY301 and is responsible for the link between the first communication node device and the second communication node device. Layer 2 305 includes a MAC (Medium Access Control) sub-layer 302, an RLC (Radio Link Control) sub-layer 303, and a PDCP (Packet Data Convergence Protocol) sub-layer 304, and these sub-layers terminate at the second communication node device.

[0243] Example 4

[0244] Example 4 illustrates a schematic diagram of a first communication device and a second communication device according to an embodiment of the present application, as shown in the appendix Figure 4 shown. The appendix Figure 4 is a block diagram of a first communication device 410 and a second communication device 450 that communicate with each other in an access network.

[0245] The first communication device 410 includes a controller / processor 475, a memory 476, a receiving processor 470, a transmitting processor 416, a multi-antenna receiving processor 472, a multi-antenna transmitting processor 471, a transmitter / receiver 418, and an antenna 420.

[0246] The second communication device 450 includes a controller / processor 459, a memory 460, a data source 467, a transmitting processor 468, a receiving processor 456, a multi-antenna transmitting processor 457, a multi-antenna receiving processor 458, a transmitter / receiver 454, and an antenna 452.

[0247] In the transmission from the first communication device 410 to the second communication device 450, at the first communication device 410, upper layer data packets from the core network are provided to the controller / processor 475. The controller / processor 475 implements the functionality of the L2 layer. In the DL (DownLink), the controller / processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to the second communication device 450 based on various priority metrics. The controller / processor 475 is also responsible for HARQ operations, retransmission of lost packets, and signaling to the second communication device 450. The transmit processor 416 and the multi-antenna transmit processor 471 implement various signal processing functions for the L1 layer (i.e., the physical layer). The transmit processor 416 implements encoding and interleaving to facilitate forward error correction (FEC) at the second communication device 450, and constellation mapping based on various modulation schemes (e.g., on-off keying (OOK), binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), M-phase shift keying (M-PSK), M-quadrature amplitude modulation (M-QAM)). The multi-antenna transmit processor 471 performs digital space precoding on the encoded and modulated symbols, including codebook-based precoding and non-codebook-based precoding, and beamforming processing, to generate one or more parallel streams. The transmit processor 416 then maps each parallel stream to subcarriers, multiplexes the modulated symbols with reference signals (e.g., pilots) in the time domain and / or frequency domain, and then uses the inverse fast Fourier transform (IFFT) to generate a physical channel carrying the time domain O streams. Subsequently, the multi-antenna transmit processor 471 performs transmit analog precoding / beamforming operations on the time domain multi-carrier symbol stream. Each transmitter 418 converts the baseband multi-carrier symbol stream provided by the multi-antenna transmit processor 471 into a radio frequency stream and then provides it to different antennas 420.

[0248] In the transmission from the first communication device 410 to the second communication device 450, at the second communication device 450, each receiver 454 receives signals through its respective antenna 452. Each receiver 454 recovers the information modulated onto the radio frequency carrier and converts the radio frequency stream into a baseband multi-carrier symbol stream that is provided to the receive processor 456. The receive processor 456 and the multi-antenna receive processor 458 perform various signal processing functions of the L1 layer. The multi-antenna receive processor 458 performs receive analog precoding / beamforming operations on the baseband multi-carrier symbol stream from the receivers 454. The receive processor 456 uses the Fast Fourier Transform (FFT) to convert the baseband multi-carrier symbol stream after the receive analog precoding / beamforming operations from the time domain to the frequency domain. In the frequency domain, the physical layer data signal and the reference signal are demultiplexed by the receive processor 456, where the reference signal will be used for channel estimation, and the data signal recovers any parallel streams destined for the second communication device 450 after multi-antenna detection in the multi-antenna receive processor 458. The symbols on each parallel stream are demodulated and recovered in the receive processor 456, and soft decisions are generated. Subsequently, the receive processor 456 decodes and de-interleaves the soft decisions to recover the upper layer data and control signals transmitted by the first communication device 410 on the physical channel. Subsequently, the upper layer data and control signals are provided to the controller / processor 459. The controller / processor 459 performs the functions of the L2 layer. The controller / processor 459 may be associated with a memory 460 that stores program code and data. The memory 460 may be referred to as a computer-readable medium. In the DL, the controller / processor 459 provides demultiplexing between the transmission and the logical channels, packet reassembly, decryption, header decompression, control signal processing to recover upper layer data packets from the core network. Subsequently, the upper layer data packets are provided to all protocol layers above the L2 layer. Various control signals may also be provided to the L3 for L3 processing. The controller / processor 459 is also responsible for error detection using the acknowledgement (ACK) and / or negative acknowledgement (NACK) protocols to support HARQ operations.

[0249] In the transmission from the second communication device 450 to the first communication device 410, at the second communication device 450, a data source 467 is used to provide upper layer data packets to a controller / processor 459. The data source 467 represents all protocol layers above the L2 layer. Similar to the transmission function at the first communication device 410 described in DL, the controller / processor 459 implements header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on the radio resource allocation of the first communication device 410, and implements L2 layer functions for both the user plane and the control plane. The controller / processor 459 is also responsible for HARQ operations, retransmission of lost packets, and signaling to the first communication device 410. A transmit processor 468 performs modulation mapping and channel coding processing, and a multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming processing. Subsequently, the transmit processor 468 modulates the generated parallel streams into multi-carrier / single-carrier symbol streams, and after passing through analog precoding / beamforming operations in the multi-antenna transmit processor 457, provides them to different antennas 452 via a transmitter 454. Each transmitter 454 first converts the baseband symbol stream provided by the multi-antenna transmit processor 457 into a radio frequency symbol stream and then provides it to the antenna 452.

[0250] In the transmission from the second communication device 450 to the first communication device 410, the functions at the first communication device 410 are similar to the receiving functions at the second communication device 450 described in the transmission from the first communication device 410 to the second communication device 450. Each receiver 418 receives radio frequency signals through its corresponding antenna 420, converts the received radio frequency signals into baseband signals, and provides the baseband signals to a multi-antenna receive processor 472 and a receive processor 470. The receive processor 470 and the multi-antenna receive processor 472 jointly implement L1 layer functions. A controller / processor 475 implements L2 layer functions. The controller / processor 475 may be associated with a memory 476 that stores program code and data. The memory 476 may be referred to as a computer-readable medium. The controller / processor 475 provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover upper layer data packets from the second communication device 450. The upper layer data packets from the controller / processor 475 may be provided to the core network. The controller / processor 475 is also responsible for error detection using the ACK and / or NACK protocols to support HARQ operations.
