Description

Technical Field

[0001] This application relates to a transmission method and apparatus in a wireless communication system, and particularly to a solution and apparatus for handling signal reception conflicts in Internet of Things (IoT) communication. Background Art

[0002] The application scenarios of future wireless communication systems are becoming more and more diversified, and different application scenarios pose different performance requirements on the system. In order to meet the different performance requirements of various application scenarios, the research on new radio (NR) (or 5G) technology was initiated at the 72nd plenary session of 3GPP (3rd Generation Partner Project). With the wide application of 5G, new business models and new application scenarios are emerging continuously, such as Ambient Internet of Things. The existing 5G standards cannot fully meet the new requirements, so 3GPP is preparing to start relevant preliminary research. Summary of the Invention

[0003] In the 5G NR system, the research work on Ambient Internet of Things (A-IoT) was initiated in Rel-19. In Ambient Internet of Things, OOK is expected to be used for transmission between a reader and an IoT device and between an IoT device and a reader. This research work has just started. In Ambient Internet of Things, considering the hardware or capability limitations of the reader, the reader device is less likely to decode the D2R signal at the radio frequency end when there is a conflict between the downlink transmission of the base station and the D2R transmission. Moreover, the research on conflict handling for transmission or reception at the reader is still in its initial stage. In addition, the applicant anticipates through research that Ambient Internet of Things will also become an important part of future 6G networks, and the design for handling signal reception conflicts in 5G NR is very likely to be adopted in 6G networks.

[0004] Regarding the problem of conflict handling for downlink transmission and D2R transmission, this application discloses a solution. It should be noted that in the description of this application, the transmission between the reader and the Internet of Things device is taken as a typical application scenario or example; this application is also equally applicable to 6G networks or other scenarios facing similar problems in the future (such as other scenarios using OOK, or other scenarios supporting transmission time control, such as full-duplex scenarios, or scenarios supporting user equipment to user equipment transmission, or for different application scenarios, such as eMBB, URLLC, full-duplex networks, non-terrestrial networks, integrated communication and sensing networks, intelligent metasurfaces, terahertz networks, V2X can also achieve similar technical effects. In addition, adopting a unified solution for different scenarios (including but not limited to eMBB, URLLC, full-duplex networks, non-terrestrial networks, integrated communication and sensing networks, intelligent metasurfaces, terahertz networks, V2X scenarios) or different application parameters helps to reduce hardware complexity and cost.

[0255] Example 3

[0256] Embodiment 3 shows a schematic diagram of the radio protocol architecture of the user plane and the control plane according to an embodiment of the present application, as shown in the appendix Figure 3 as follows. Figure 3 It is a schematic diagram illustrating an embodiment of the radio protocol architecture for the user plane 350 and the control plane 300. Figure 3The radio protocol architecture of the control plane 300 for terminals and Internet of Things (IoT) devices is shown in three layers: Layer 1, Layer 2, and Layer 3. Layer 1 (L1 layer) is the lowest layer and implements various PHY (Physical Layer) signal processing functions. Layer 1 will be referred to as PHY 301 in this document. Layer 2 (L2 layer) 305 is on top of PHY 301 and is responsible for the link between the terminal and the IoT device via PHY 301. Layer 2 305 includes a MAC (Medium Access Control) sublayer 302, an RLC (Radio Link Control) sublayer 303 (if supported by the IoT device), and a PDCP (Packet Data Convergence Protocol) sublayer 304 (if supported by the IoT device), and these sublayers terminate at the IoT device. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. The PDCP sublayer 304 also provides security by encrypting data packets and provides mobility support for the terminal device among IoT devices. The RLC sublayer 303 provides segmentation and reassembly of upper layer data packets, retransmission of lost data packets, and reordering of data packets to compensate for disordered reception due to HARQ (if supported by the IoT device). The MAC sublayer 302 provides multiplexing between logical and transport channels. The MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) in a cell among terminal devices. The MAC sublayer 302 is also responsible for HARQ operations. The RRC (Radio Resource Control) sublayer 306 in Layer 3 (L3 layer) of the control plane 300 is responsible for obtaining radio resources (i.e., radio bearers) and configuring the lower layers using RRC signaling between the IoT device and the terminal. The radio protocol architecture of the user plane 350 includes Layer 1 (L1 layer) and Layer 2 (L2 layer). In the user plane 350, the radio protocol architecture for terminals and IoT devices is generally the same as the corresponding layers and sublayers in the control plane 300 for the physical layer 351, the PDCP sublayer 354 in L2 layer 355 (if supported by the IoT device), the RLC sublayer 353 in L2 layer 355 (if supported by the IoT device), and the MAC sublayer 352 in L2 layer 355, but the PDCP sublayer 354 also provides header compression for upper layer data packets to reduce radio transmission overhead.The L2 layer 355 in the user plane 350 further includes an SDAP (Service Data Adaptation Protocol) sub-layer 356 (if supported by the Internet of Things device). The SDAP sub-layer 356 is responsible for the mapping between QoS flows and data radio bearers (DRBs) to support the diversity of services.

[0261] Example 4

[0262] Embodiment 4 shows a schematic diagram of a terminal and an Internet of Things device according to an embodiment of this application, as shown in the appendix Figure 4 as shown.

[0263] The terminal (410) may include a controller / processor 440, a memory 430, a receiving processor 412, a transmitter / receiver 416, and a transmitting processor 415. The transmitter / receiver 416 includes an antenna 420.

[0264] The Internet of Things device (450) may include a controller / processor 490 (if supported), a memory 480, a receiving processor 452, a transmitter / receiver 456, and a transmitting processor 455. The transmitter / receiver 456 includes an antenna 460.

[0265] In the transmission from the terminal to the Internet of Things device, the upper layer packet is provided to the controller / processor 440. The controller / processor 440 implements the functions of the L2 layer and above. The controller / processor 440 provides packet header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation based on various priority metrics. The controller / processor 440 is also responsible for HARQ operations, retransmission of lost packets (if supported), and high layer signaling to the Internet of Things device 450. The high layer information carried by the first PRDCH in this application is generated by the controller / processor 440. The transmit processor 415 implements various signal processing functions for the L1 layer (i.e., the physical layer), including coding, interleaving, scrambling, modulation, power control / allocation, precoding, and physical layer control signaling generation, etc. For example, the physical layer signal carrying the first PRDCH is completed by the transmit processor 415. The generated modulation symbols are divided into parallel streams and each stream is mapped to the corresponding multi-carrier sub-carriers and / or multi-carrier symbols, and then mapped by the transmit processor 415 to the antenna 420 via the transmitter 416 and transmitted in the form of radio frequency signals. At the receiving end, each receiver 456 receives radio frequency signals through its corresponding antenna 460. Each receiver 456 recovers the baseband information modulated onto the radio frequency carrier (if baseband processing is supported), and provides the baseband information to the receive processor 452. The receive processor 452 implements various signal reception processing functions of the L1 layer. The signal reception processing functions include receiving the physical layer signal carrying the first PRDCH in this application, performing demodulation based on various modulation schemes (e.g., on-off keying (OOK), binary phase shift keying (BPSK)), followed by descrambling, decoding, and deinterleaving (if supported) to recover the data or control transmitted by the terminal 410 on the physical channel, and then providing the data and control signals to the controller / processor 490 (if the Internet of Things device supports it). The controller / processor 490 is responsible for the L2 layer and above. The controller / processor 490 interprets the high layer information. This includes interpreting the high layer information carried by the first PRDCH. The controller / processor may be associated with a memory 480 that stores program code and data. The memory 480 may be referred to as a computer-readable medium.

[0266] In the transmission from the IoT device to the terminal, similar to the transmission from the terminal to the IoT device, after the high-layer information carried by the first PDRCH is generated by the controller / processor 490 (if the IoT device supports it), various signal transmission processing functions for the L1 layer (i.e., the physical layer) are implemented by the transmission processor 455. The transmission processor 455 includes mapping the physical layer signal of the first PDRCH to the antenna 460 via the transmitter 456 and transmitting it in the form of a radio frequency signal. The receiver 416 receives the radio frequency signal through its corresponding antenna 420. Each receiver 416 recovers the baseband information modulated onto the radio frequency carrier and provides the baseband information to the receiving processor 412. The receiving processor 412 implements various signal reception processing functions for the L1 layer (i.e., the physical layer), and then provides data and / or control signals to the controller / processor 440. Implementing the functions of the L2 layer in the controller / processor 440 includes interpreting the high-layer information. The controller / processor may be associated with a memory 430 that stores program code and data. The memory 430 may be a computer-readable medium.

[0562] Example 14 illustrates a schematic diagram of the structure of an A-IoT device according to an embodiment of the present application, as shown in the appendix Figure 14 as follows.

[0563] In the appendix Figure 14In this case, the A-IoT device 1400 includes an antenna 1401, an energy-related module 1404, and a processing-related module 1408. The A-IoT device 1400 may further include a matching network 1402, which is used to match the impedance between the antenna 1401 and other components (including the radio frequency (RF) energy harvester 1403 and the reception-related module 1409). The A-IoT device 1400 may also include an energy harvester, which may be the RF energy harvester 1403 or a non-RF energy harvester 1407. The RF energy harvester 1403 may include a rectifier that performs the conversion of RF signals (AC) to DC. The RF energy harvester 1403 and the receiver / transmitter may share the antenna 1401, or the RF energy harvester 1403 and the receiver / transmitter may also use independent antennas. The energy-related module 1404 may include a Power management unit (PMU) 1405; the PMU 1405 is responsible for storing the energy from the energy harvester into the energy storage 1406 and supplying power to the active component blocks that require power supply. The energy-related module 1404 may also include an Energy storage 1406; the energy storage 1406 stores the energy collected from the energy harvester, and the energy storage 1406 may be a capacitor. The processing-related module 1408 may include BB (BaseBand) logic 1413 (if supported), a Memory 1418, and a clock generator 1419; the BB logic 1413 may include a decoder 1414, a controller 1415, and an encoder 1416; the Memory 1418 may include two types. One is a Non-Volatile Memory (NVM), such as EEPROM, which is used to permanently store the device ID; the other is a register, which is used to temporarily save the information that is only required temporarily for operation when the energy in the energy storage 1406 is available; the clock generator 1419 provides the required clock signals. The processing-related module 1408 may also include Reception related blocks 1409 and Transmission-related blocks 1417. For different A-IoT devices, the Reception related blocks 1409 and the Transmission-related blocks 1417 may include different modules.

[0564] As an example, for an A-IoT device 1400 with a peak power consumption of about 1 μW, the receiving-related module 1409 may include an RF BPF 1410, an RF envelope detector (RF-ED), a BB LPF 1411, and a comparator 1412. The transmitting-related module 1417 may include a Backscatter modulator.

[0565] As a non-limiting example, the output of the matching network 1402 is sequentially processed by the RF BPF 1410, the RF envelope detector, the BB LPF 1411, and the comparator 1412 and then input to the BB logic 1413. The output of the BB logic 1413 is processed by the Backscatter modulator and then transmitted by the antenna 1401.

[0566] As an example, for an A-IoT device 1400 with a peak power consumption less than or equal to a few hundred μW, if an External carrier wave is used, the receiving-related module 1409 may include an RF BPF 1410, an LNA (Low-noise amplifier), an RF envelope detector, a BB amplifier, a BB LPF 1411, and a comparator / N-bit ADC 1412. The transmitting-related module 1417 may include a Large Frequency shifter (e.g., dozens of megahertz), a Backscatter modulator, and a Reflection amplifier. At least one of R2D (Reader to device) / CW2D (Carrier-wave, or carrier-wave node, to device) and D2R (Device to reader) may be amplified by the Reflection amplifier or the LNA. The Large Frequency shifter transfers the Backscatter signal from one frequency (e.g., the FDD-DL frequency) to another frequency (e.g., the FDD-UL frequency).

[0567] As a non-limiting example, the output of the matching network 1402 is sequentially processed by the RF BPF 1410, the LNA, the RF envelope detector, the BB amplifier, the BB LPF 1411, and the comparator / N-bit ADC 1412 and then input to the BB logic 1413. The output of the BB logic 1413 is processed by the Large Frequency shifter, the Backscatter modulator, and the Reflection amplifier and then transmitted by the antenna 1401.

[0568] As an example, for an A-IoT device 1400 with a peak power consumption less than or equal to a few hundred μW, if an internally-generated carrier wave is adopted and an RF envelope detector receiver is used, the receiving-related module 1409 may include an RF BPF 1410, an LNA, an RF envelope detector, a BB amplifier, a BB LPF 1411, and a comparator / N-bit ADC 1412. The transmitting-related module 1417 may include a Tx Modulator, a Digital to Analog Converter (DAC), a low pass filter, a mixer, a LO (Local Oscillator, local oscillator) / FLL ( / PLL), and a Power Amplifier (PA).

[0569] As a non-limiting example, the output of the matching network 1402 is successively processed by an RF BPF 1410, an LNA, an RF envelope detector, a BB amplifier, a BB LPF 1411, and a comparator / N-bit ADC 1412 and then input to the BB logic 1413. The output of the BB logic 1413 is transmitted by the antenna 1401 after being processed by a Tx Modulator, a Digital to Analog Converter, a low pass filter, a mixer, a LO / FLL ( / PLL), and a Power Amplifier.

[0570] As an example, for an A-IoT device 1400 with a peak power consumption less than or equal to a few hundred μW, if an internally-generated carrier wave is adopted and an intermediate-frequency (IF) envelope detector receiver is used, the receiving-related module 1409 may include an RF BPF 1410, an LNA, a mixer, an IF amplifier, an IF filter, an IF envelope detector (IF-ED), a BB amplifier, a BB LPF 1411, and a comparator / N-bit ADC 1412. The transmitting-related module 1417 may include a transmit modulator, a digital-to-analog converter, a low-pass filter, a mixer, an LO / FLL( / PLL), and a power amplifier. The IF amplifier amplifies the IF signal. The IF filter filters out unwanted radio frequency and LO signals. The IF envelope detector detects the envelope from the IF signal. The mixer in the receiving-related module 1409 down-converts the radio frequency signal to the IF stage. Depending on the implementation, there may be one or two mixers for the transmitter and the receiver.

[0571] As a non-limiting example, the output of the matching network 1402 is sequentially processed by an RF BPF 1410, an LNA, a mixer, an IF amplifier, an IF filter, an IF envelope detector, a BB amplifier, a BB LPF 1411, and a comparator / N-bit ADC 1412 and then input to the BB logic 1413. The output of the BB logic 1413 is processed by a transmit modulator, a digital-to-analog converter, a low-pass filter, a mixer, an LO / FLL( / PLL), and a power amplifier and then transmitted by the antenna 1401.

[0572] As an example, for an A-IoT device 1400 with a peak power consumption less than or equal to a few hundred μW, if an internally-generated carrier wave is adopted and a zero-IF (ZIF) receiver is used, the receiving-related module 1409 may include an RF BPF 1410, an LNA, a mixer, a BB amplifier, a BB LPF 1411, and a comparator / N-bit ADC 1412. The transmitting-related module 1417 may include a transmit modulator, a digital-to-analog converter, a low-pass filter, a mixer, an LO / FLL( / PLL), and a power amplifier. The mixer in the receiving-related module 1409 down-converts the radio frequency signal to the BB stage. Depending on the implementation, there may be one or two mixers for the transmitter and the receiver.

[0573] As a non-limiting example, the output of the matching network 1402 is successively processed by the RF BPF 1410, LNA, mixer, BB amplifier, BB LPF 1411, comparator / N-bit ADC 1412 and then input to the BB logic 1413. The output of the BB logic 1413 is processed by a transmit modulator, digital-to-analog converter, low-pass filter, mixer, LO / FLL( / PLL) and power amplifier and then transmitted by the antenna 1401.

[0574] In the above several embodiments, the RF BPF 1410 is used to enhance selectivity. Based on implementation, the RF BPF 1410 may not exist. The BB LPF 1411 is used to filter out harmonics and high-frequency components to improve the input signal quality of the comparator / ADC 1412. Based on implementation, the BB LPF 1411 may not exist. The comparator 1412 is used to detect the high / low of the input signal. The backscatter modulator is used to convert the impedance into a modulated backscatter signal carrying the transmit signal from the BB logic 1413. The LNA is used to increase the signal strength and receive sensitivity. The RF envelope detector is used to detect the envelope from the RF signal. The BB amplifier is used to amplify the signal to increase the signal strength. The transmit modulator is used to modulate the baseband bits according to the modulation method; the transmit modulator may be part of the BB logic 1413. The digital-to-analog converter is used to convert the digital signal into an analog signal. The low-pass filter is used to filter out unwanted signals. The mixer in the transmit-related module 1417 is used to up-convert the baseband signal to the RF range. The LO is used to generate the carrier frequency; the FLL( / PLL) can be used for frequency synthesis. Based on implementation, the FLL( / PLL) may not exist. The power amplifier is used to amplify the transmit signal.

Specifically, according to the different functions and actual application scenarios of the A-IoT device, the A-IoT device may adopt the structure of the A-IoT device in this example, may also include only some modules in the structure of the A-IoT device in this example, or may also include Figure 14 other modules not shown.
