In order to meet the different performance requirements of various application scenarios, the research on new air interface technology (NR, New Radio) (or 5G) 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 constantly emerging, such as Ambient Internet of Things.

This research work has just started. The applicant anticipates through research that the ambient Internet of Things will also become an important part of the future 6G network.

Figure 3is a schematic diagram illustrating an embodiment of a radio protocol architecture for a user plane 350 and a control plane 300, Figure 3The radio protocol architecture of the control plane 300 for terminals, base stations, 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 base station through PHY 301. Layer 2 305 includes a MAC (Medium Access Control) sublayer 302, an RLC (Radio Link Control Protocol) sublayer 303, and a PDCP (Packet Data Convergence Protocol) sublayer 304, and these sublayers terminate at the base station or 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 handover support for the terminal between base stations and mobility support for the terminal device between 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 out-of-order reception due to HARQ. 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 terminals. 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 base station and the terminal. The radio protocol architecture of the user plane 350 includes Layer 1 (L1 layer) and Layer 2 (L2 layer).

[0206] 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 layers. 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 first information block in this application and the high layer information carried by the first PRDCH in this application are 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 / assignment, precoding, and physical layer control signaling generation, etc. For example, the physical layer signal carrying the first information block in this application and the first PRDCH in this application are 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 are mapped by the transmit processor 415 via the transmitter 416 to the antenna 420 and transmitted in the form of radio frequency signals. At the receiving end, each receiver 456 receives the 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 receiving processing functions of the L1 layer. The signal receiving processing functions include the reception of the physical layer signal carrying the first information block in this application and the first PRDCH in this application, and are performed 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 the data and control signals are provided to the controller / processor 490 (if the Internet of Things device supports). The controller / processor 490 is responsible for the L2 layer and above layers. The controller / processor 490 interprets the high layer information. This includes interpreting the high layer information carried by the first information block in this application and the first PRDCH in this application. 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.

[0207] 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 is generated by the controller / processor 490 (if the IoT device supports it), the transmitting processor 455 performs various signal transmission processing functions for the L1 layer (i.e., the physical layer). The physical layer signals are mapped by the transmitting processor 455 to the antenna 460 via the transmitter 456 and transmitted in the form of radio frequency signals. The receiver 416 receives the radio frequency signals 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 performs 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. The functions implemented by the controller / processor 440 for the L2 layer include interpreting the high-layer information.

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 need 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, 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 temporarily needed for operation when the energy in the energy storage 1406 is available; the clock generator 1419 provides the required clock signal. 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 module 1409 and the Transmission related module 1417 may include different modules.

[0629] 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, a radio frequency envelope detector (RF-ED), a BB LPF 1411, and a comparator 1412. The transmitting related module 1417 may include a backscatter modulator.

The output of the BB logic 1413 is processed by the backscatter modulator and then transmitted by the antenna 1401.

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 backscattered signal from one frequency (e.g., the FDD-DL frequency) to another frequency (e.g., the FDD-UL frequency).

[0632] As a non-limiting example, the output of the matching network 1402 is sequentially processed by the RF BPF 1410, the LNA, the radio frequency 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.

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 Lowpass filter, a mixer, a LO / FLL( / PLL), and a Power amplifier.

The IF amplifier amplifies the IF signal. The IF filter filters out unwanted RF 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 RF signal to the IF stage. Depending on the implementation, there may be one or two mixers for the transmitter and the receiver.

[0636] 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.

[0637] 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 RF signal to the BB stage. Depending on the implementation, there may be one or two mixers for the transmitter and the receiver.

[0638] As a non-limiting example, the output of matching network 1402 is sequentially processed by RF BPF 1410, LNA, mixer, BB amplifier, BB LPF 1411, comparator / N-bit ADC 1412 and then input to BB logic 1413. The output of 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 antenna 1401.

[0639] In the above several embodiments, RF BPF 1410 is used to enhance selectivity. Based on implementation, RF BPF 1410 may not exist. BB LPF 1411 is used to filter out harmonics and high-frequency components to improve the input signal quality of comparator / ADC 1412. Based on implementation, BB LPF 1411 may not exist. Comparator 1412 is used to detect the high / low of the input signal. The backscatter modulator is used to convert impedance into a modulated backscatter signal carrying the transmit signal from BB logic 1413. LNA is used to increase 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 signal strength. The transmit modulator is used to modulate baseband bits according to the modulation method; the transmit modulator may be part of BB logic 1413. The digital-to-analog converter is used to convert digital signals into analog signals. The low-pass filter is used to filter out unwanted signals. The mixer in 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; FLL( / PLL) can be used for frequency synthesis. Based on implementation, FLL( / PLL) may not exist. The power amplifier is used to amplify the transmit signal.
