Description

A method and apparatus used in a node for wireless communication and Internet of Things TECHNICAL FIELD

[0001] The present application relates to a signal transmission method and apparatus in a wireless communication system, and in particular to a method and apparatus for scheduling transmission. BACKGROUND

[0002] The application scenarios of future wireless communication systems are increasingly diversified, and different application scenarios have different performance requirements for the system. In order to meet the different performance requirements of various application scenarios, the research on New Radio (NR) (or 5G) was started at the 72nd plenary meeting of 3GPP (3rd Generation Partnership Project) RAN (Radio Access Network). With the wide application of 5G, new business models and new application scenarios are emerging, and the existing 5G standard cannot fully meet the new requirements, so 3GPP is preparing to start the preliminary research on 6G.

[0003] With the diversification of application scenarios and the emergence of new business models, the demand for low complexity and low power transmission schemes is increasing, so 6G needs to explore wireless transmission methods that better adapt to and support low complexity and low power. SUMMARY

[0004] 5G NR system started the research of low power wake up signal (LP-WUS) and ambient Internet of Things in Rel-18 and Rel-19 respectively, in which the ambient Internet of Things device is often woken up by receiving the excitation signal and starts to communicate with the surrounding terminal device. Since the ambient Internet of Things device has low cost and limited baseband capability, the transmission based on the excitation signal is often aimed at the reflection or feedback of the excitation signal. At the same time, since the transmission capability of the ambient Internet of Things device is limited, reporting the characteristics of the ambient Internet of Things device, such as the transmission and reception delay and power loss, to the network will help to exert the characteristics of the ambient Internet of Things device, and further improve the overall performance of the system.

[0005] Aiming at the problem of reporting the self characteristics of the environmental Internet of Things device, a solution is disclosed. It should be noted that in the description of the present application, only the uplink transmission and the transmission of the reader to the environmental Internet of Things device are taken as a typical application scenario or example; the present application is also applicable to 6G network or other scenarios facing similar problems in the future (for example, there are scenarios that need to perform physical layer bit padding, or other scenarios that do not support forward error correction code encoding, such as energy saving scenarios, or user equipment to user equipment transmission scenarios, or for different application scenarios, such as eMBB (Enhanced Mobile Broadband, Enhanced Mobile Broadband), URLLC (Ultra Reliable and Low Latency Communications, Ultra Reliable and Low Latency Communications), full-duplex network, non-terrestrial network, integrated sensing network, intelligent metasurface, terahertz network, V2X can also achieve similar technical effects. In addition, adopting a unified solution for different scenarios (including but not limited to eMBB, URLLC, energy saving, Internet of Things, full-duplex network, non-terrestrial network, integrated sensing network, intelligent metasurface, terahertz network, V2X scenarios) or different application parameters also helps to reduce hardware complexity and cost. In the case of no conflict, the embodiments and features in the embodiments of the device used for the first node in the present application can be applied to the device used for the second node in the present application, and vice versa.

[0211] Embodiment 4

[0212] 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.

[0213] The first communication device 410 includes a controller / processor 475, a memory 476, a receive processor 470, a transmit processor 416, a multi-antenna receive processor 472, a multi-antenna transmit processor 471, a transmitter / receiver 418, and an antenna 420.

[0214] 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 multi-antenna transmit processor 457, a multi-antenna receive processor 458, a transmitter / receiver 454, and an antenna 452.

[0215] In transmissions from the first communication device 410 to the second communication device 450, at the first communication device 410, upper layer packets from the core network are provided to the controller / processor 475. The controller / processor 475 implements functionality of L2. In DL, the controller / processor 475 provides header compression, ciphering, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocations for 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 Ll (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 mapping onto signal constellations based on various modulation schemes (e.g., binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), M-ary phase shift keying (M-PSK), M-ary quadrature amplitude modulation (M-QAM)). The multi-antenna transmit processor 471 performs digital spatial pre-coding of the coded and modulated symbols, including codebook-based and non-codebook-based pre-coding and beamforming processing, to generate one or more parallel streams. The transmit processor 416 then maps to each of the parallel streams to subcarriers, multiplexes the modulated symbols in time domain and / or frequency domain with reference signals (e.g., pilot) and then performs an inverse fast Fourier transform (IFFT) to generate time domain multicarrier symbol streams. The multi-antenna transmit processor 471 then performs transmit analog pre-coding / beamforming operations on the time domain multicarrier symbol streams. Each transmitter 418 converts the baseband multicarrier symbol streams provided by the multi-antenna transmit processor 471 into radio frequency signals that are transmitted via the corresponding antennas 420.

[0216] 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 receive processor 456. The receive processor 456 and the multi-antenna receive processor 458 implement various signal processing functions of the LI. The multi-antenna receive processor 458 performs receive analog precoding / beamforming operation 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 operation 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, where the reference signals will be used for channel estimation, and the data signals are recovered after multi-antenna detection in the multi-antenna 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 the controller / processor 459. The controller / processor 459 implements the functions of the L2. 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. 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 ACK and / or negative ACK (NACK) protocol to support HARQ operations.

[0217] 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 L2. 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 pre-coding including codebook-based and non-codebook-based precoding, and beamforming processing, and then the transmit processor 468 generates parallel streams of symbols that are modulated onto different carriers, and the modulated symbol streams are then provided to different antennas 452 via transmitters 454 after analog pre-coding / beamforming operations in the multi-antenna transmit processor 457. Each transmitter 454 converts a baseband symbol stream into a radio frequency signal that is transmitted via the corresponding antenna 452.

[0218] 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 together implement L1 functionality. A controller / processor 475 implements L2 functionality. 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.
