Description

A method and apparatus for wireless communication

[0001] This application claims priority to the Chinese Patent Application No. 202411359893.9, filed on September 27, 2024, and entitled "A method and apparatus for wireless communication", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to a method and apparatus in a wireless communication system, and in particular, to a solution and apparatus related to determining the existence of an AIoT device in the vicinity based on the cell not supporting the configuration of AIoT functions in a wireless communication system. BACKGROUND

[0003] In recent years, IoT (Internet of Things) has attracted much attention in the field of wireless communication, and hundreds of billions or even trillions of IoT devices can improve production efficiency and enhance life comfort. Most existing wireless communication devices need to be manually replaced or charged, which can lead to high maintenance costs, and even in some scenarios (such as wireless sensors in the power and oil industries), there are safety hazards. Today, automation and digitization in various industries open up many new markets, for example, most industries use barcodes and RFID (Radio Frequency Identification) technology 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-free devices or energy storage devices that do not require manual replacement or charging.

[0004] 3GPP (3rd Generation Partnership Project, the third generation partnership project) R (Release, version) 18 begins to study AIoT (Ambient Internet of Things, ambient Internet of Things), and the implementation of the system needs to rely on ultra-low complexity devices and ultra-low power consumption technology. These ultra-low complexity devices are called AIoT devices. AIoT devices are a kind of IoT devices powered by energy harvesting, either without battery or with limited energy storage capability (for example, using capacitors). In the AIoT system, the Reader function can be deployed in the UE (User Equipment, user equipment), which is mainly responsible for discovering nearby AIoT devices and performing AIoT-related command operations (such as reading / writing data, etc.) on them. Based on the progress of R19 research, the Reader can interact with nearby AIoT devices through wireless connections with AIoT devices according to the instructions of the node (for example, the core network element supporting AIoT function) controlling the AIoT function. SUMMARY

[0005] The applicant found through research that when the AIoT function is introduced, the UE deploying the Reader function needs to consider the support of the RAN node for configuring the AIoT function when determining whether there is an AIoT device nearby, otherwise it may not be able to guarantee the continuity and reliability of the Reader providing AIoT services.

[0006] To solve the above problems, a solution is disclosed in the present application.

In addition, using a unified solution in different scenarios also helps to reduce hardware complexity and cost.

[0244] Embodiment 4

[0245] Embodiment 4 illustrates a schematic diagram of a first communication device and a second communication device according to one embodiment of the present application, as shown in FIG. 4. FIG. 4 is a block diagram of a first communication device 410 and a second communication device 450 communicating with each other in an access network.

[0246] The first communication device 410 includes a controller / processor 475, a memory 476, a receive processor 470, a transmit processor 416, a multiple antenna receive processor 472, a multiple antenna transmit processor 471, a transmitter / receiver 418, and an antenna 420.

[0247] The second communication device 450 includes a controller / processor 459, a memory 460, a data source 467, a transmit processor 468, a receive processor 456, a multiple antenna transmit processor 457, a multiple antenna receive processor 458, a transmitter / receiver 454, and antennas 452.

[0248] In the transmission from the first communication device 410 to the second communication device 450, at the first communication device 410, upper layer packets from a core network are provided to the controller / processor 475. The controller / processor 475 implements functionality of the L2 layer. In the DL (DownLink), the controller / processor 475 provides header compression, ciphering, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocations for 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 multiple antenna transmit processor 471 implement various signal processing functions for the LI layer (i.e., physical layer). The transmit processor 416 implements coding 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 multiple antenna transmit processor 471 performs digital spatial precoding on the coded and modulated symbols, including codebook-based precoding and non-codebook-based precoding, and beamforming processing, generating one or more parallel streams. The transmit processor 416 then maps to each parallel stream to a subcarrier, multiplexes the modulated symbols in the time and / or frequency domain with reference signals (e.g., pilot signals), and then performs a fast Fourier transform (IFFT) to generate a time-domain OFDM stream. The multiple antenna transmit processor 471 then performs transmit analog precoding / beamforming operations on the time-domain multicarrier symbol streams. Each transmitter 418 converts the baseband multicarrier symbol streams provided by the multiple antenna transmit processor 471 into radio frequency streams, which are then provided to different antennas 420.

[0249] In transmission from the first communication device 410 to the second communication device 450, at the second communication device 450, each receiver 454 receives a signal through its respective antenna 452. Each receiver 454 recovers information modulated onto an RF carrier and converts the RF stream into a baseband, multicarrier symbol stream to be provided to a receive processor 456. The receive processor 456 and a multiple access receive processor 458 implement various signal processing functions of the Ll layer. The multiple access receive processor 458 performs receive analog precoding / beamforming operations on the baseband, multicarrier symbol stream from the receivers 454. The receive processor 456 converts the baseband, multicarrier symbol stream from the receive analog precoding / beamforming operations from the time domain to the frequency domain using a Fast Fourier Transform (FFT). In the frequency domain, the physical layer data signals and the reference signals are demultiplexed by the receive processor 456, with the reference signals to be used for channel estimation and the data signals to be recovered after multi-antenna detection in the multiple access receive processor 458 for any parallel streams destined to the second communication device 450. The symbols on each parallel stream are demodulated and recovered in the receive processor 456 and generate soft decisions. The receive processor 456 then 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 channels. The upper layer data and control signals are then provided to a controller / processor 459. The controller / processor 459 implements the functions of the L2 layer. The controller / processor 459 can be associated with a memory 460 that stores program codes and data. The memory 460 can be referred to as a computer-readable medium. In the DL, the controller / processor 459 provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, control signal processing to recover upper layer data packets from the core network. The upper layer data packets are then provided to all protocol layers above the L2 layer. Various control signals can also be provided to the L3 for L3 processing. The controller / processor 459 is also responsible for error detection using an acknowledgement (ACK) and / or negative acknowledgement (NACK) protocol to support HARQ operations.

[0250] 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 packets to a controller / processor 459. The data source 467 represents all protocol layers above the L2 layer. Similar to the transmit function described at the first communication device 410 in the DL, the controller / processor 459 implements header compression, ciphering, packet segmentation and reordering, and multiplexing between logical and transport channels based on radio resource allocations for the first communication device 410, implements L2 layer functionality for the user plane and 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, in conjunction with a multi-antenna transmit processor 457, performs modulation mapping, channel coding processing, digital multi-antenna spatial processing, including codebook-based and non-codebook-based precoding, and beamforming processing, and then the transmit processor 468 creates parallel streams of coded and modulated symbols for the different antenna ports, which are provided to different antennas 452 via separate transmitters 454 after analog precoding / beamforming at the multi-antenna transmit processor 457. Each transmitter 454 then converts the baseband streams into radio frequency signals and transmits the radio frequency signals via the antennas 452.

[0251] In the transmission from the second communication device 450 to the first communication device 410, the functionality at the first communication device 410 is similar to the functionality described in connection with the reception at the second communication device 450 in the transmission from the first communication device 410 to the second communication device 450. Each receiver 418 receives a radio frequency signal through its respective antenna 420, converts the received radio frequency signal into a baseband signal, and provides the baseband signal to a multi-antenna receive processor 472 and a receive processor 470. The receive processor 470 and the multi-antenna receive processor 472, in conjunction with the controller / processor 475, implement the L1 layer functions. The controller / processor 475 implements the L2 layer functions. The controller / processor 475 can be associated with a memory 476 that stores program codes and data. The memory 476 can be referred to as a computer-readable medium. The controller / processor 475 provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, control signal processing to recover upper layer packets from the second communication device 450. Upper layer packets from the controller / processor 475 can be provided to a core network. The controller / processor 475 is also responsible for error detection using an ACK and / or NACK protocol to support HARQ operations.
