Description

A method and apparatus for use in wireless communication terminals and Internet of Things (IoT) devices.

[0001] This application claims priority to Chinese Patent Application No. 202411558165.0, filed on November 1, 2024, entitled "A Method and Apparatus for Wireless Communication in a Terminal and an Internet of Things Device", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to transmission methods and apparatus in wireless communication systems, and more particularly to schemes and apparatus for handling signal transmission conflicts in Internet of Things (IoT) communications. Background Technology

[0003] The application scenarios of future wireless communication systems are becoming increasingly diversified, and different application scenarios place different performance requirements on the system. To meet the diverse performance needs of various application scenarios, research on New Radio (NR) (or 5G) was initiated at the 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) #72 plenary meeting. With the widespread application of 5G, new business models and application scenarios are constantly emerging, such as the Ambient Internet of Things (IoT). Existing 5G standards cannot fully meet these new demands; therefore, 3GPP is preparing to begin related preliminary research. Summary of the Invention

[0004] The 5G NR system initiated research on Ambient Internet of Things (A-IoT) in Rel-19. In A-IoT, OOK is expected to be used for transmission between readers and IoT devices, and between IoT devices and readers. This research is still in its early stages. In A-IoT, considering the hardware or capability limitations of readers, reader devices are unlikely to support simultaneous uplink and R2D transmissions. Furthermore, research on collision handling at the reader level is still in its initial stages. Additionally, the applicant anticipates that A-IoT will become an important component of future 6G networks, and the signal transmission collision handling design for 5G NR is highly likely to be adopted in 6G networks.

[0005] To address the conflict between uplink and R2D transmission, this application discloses a solution. It should be noted that the description in this application uses the transmission between the reader and the IoT device as a typical application scenario or example; this application is also applicable to 6G networks or other scenarios facing similar problems in the future (e.g., other scenarios using OOK, or other scenarios supporting transmission time control, such as full-duplex scenarios, or user equipment-to-user equipment transmission scenarios, or for different application scenarios, such as eMBB, URLLC, full-duplex networks, non-terrestrial networks, sensor-integrated networks, smart metasurfaces, terahertz networks, V2X can also achieve similar technical effects). Furthermore, using a unified solution for different scenarios (including but not limited to eMBB, URLLC, full-duplex networks, non-terrestrial networks, sensor-integrated networks, smart metasurfaces, terahertz networks, V2X scenarios) or different application parameters helps reduce hardware complexity and cost. Where there is no conflict, the embodiments and features described in the terminal devices of this application can be applied to the IoT devices or base station devices described in this application, and vice versa.

[0006] This application discloses a method for use in a terminal, including:

[0009] There is an overlap between the time-domain resources allocated to the first uplink signal and the time-domain resources configured for the first PRDCH; the priority relationship between the first uplink signal and the first PRDCH depends on the relationship between the time-frequency resources occupied by the first uplink signal and the random access preamble.

[0010] As an example, when there is an overlap between the time-domain resources allocated to the first uplink signal and the time-domain resources configured for the first PRDCH, for a terminal that does not support simultaneous transmission of uplink and R2D transmission, the terminal can determine whether to transmit uplink or R2D transmission based on the priority relationship between the first uplink signal and the first PRDCH. The priority relationship between the first uplink signal and the first PRDCH depends on the relationship between the time-frequency resources occupied by the first uplink signal and the random access preamble, which improves transmission performance while reducing processing latency and complexity.

When there is an overlap between the time domain resources allocated to the second uplink signal and the time domain resources configured for the first PRDCH, the first PRDCH is transmitted with priority.

[0016] According to one aspect of this application, the above method is characterized in that whether the first PRDCH is preferentially transmitted also depends on at least one of the device type of the sender of the first PRDCH and the service type to which the first PRDCH is targeted, said device type and said service type depending on the indication of NAS or core network.

[0017] According to one aspect of this application, the above method is characterized in that the first PRDCH belongs to a first time window in the time domain, and the first time window includes at least one OFDM symbol;

[0205] Example 3

[0206] Example 3 illustrates a schematic diagram of the wireless protocol architecture for the user plane and control plane according to an embodiment of this application, as shown in Figure 3. Figure 3 is a schematic diagram illustrating an embodiment of the radio protocol architecture for the user plane 350 and control plane 300. Figure 3 shows the radio protocol architecture for the control plane 300 for terminals and IoT devices using 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. The L1 layer will be referred to herein as PHY 301. Layer 2 (L2 layer) 305 is above PHY 301 and is responsible for the link between the terminal and the IoT device through PHY 301. L2 layer 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), which terminate at the IoT device. PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. PDCP sublayer 304 also provides security through encrypted data packets and provides mobility support between IoT devices for terminal devices. RLC sublayer 303 provides upper-layer packet segmentation and reassembly, retransmission of lost packets, and packet reordering to compensate for out-of-order reception due to HARQ (if supported by the IoT device). MAC sublayer 302 provides multiplexing between logical and transport channels. MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) within a cell among terminal devices. MAC sublayer 302 is also responsible for HARQ operations. The RRC (Radio Resource Control) sublayer 306 in Layer 3 (L3) of the control plane 300 is responsible for acquiring radio resources (i.e., radio bearers) and configuring the lower layers using RRC signaling between IoT devices and terminals. The radio protocol architecture of user plane 350 includes layer 1 (L1 layer) and layer 2 (L2 layer). The radio protocol architecture for terminals and IoT devices in user plane 350 is largely the same as the corresponding layers and sublayers in control plane 300 for physical layer 351, PDCP sublayer 354 in L2 layer 355 (if supported by IoT devices), RLC sublayer 353 in L2 layer 355 (if supported by IoT devices) and MAC sublayer 352 in L2 layer 355. However, PDCP sublayer 354 also provides header compression for upper layer packets to reduce radio transmission overhead.The L2 layer 355 in the user plane 350 also includes an SDAP (Service Data Adaptation Protocol) sublayer 356 (if supported by the IoT device). The SDAP sublayer 356 is responsible for mapping between QoS streams and data radio bearers (DRBs) to support service diversity. Although not illustrated, the terminal may have several upper layers above the L2 layer 355, including a network layer (e.g., IP layer) terminating at the P-GW on the network side and an application layer terminating at the other end of the connection (e.g., a remote UE, server, etc.).

[0212] Example 4

[0213] Example 4 illustrates a schematic diagram of a terminal and an Internet of Things (IoT) device according to an embodiment of this application, as shown in Figure 4.

[0214] The terminal (410) may include a controller / processor 440, a memory 430, a receiver processor 412, a transmitter / receiver 416 and a transmitter processor 415, the transmitter / receiver 416 including an antenna 420.

[0215] The Internet of Things device (450) may include a controller / processor 490 (if supported), a memory 480, a receiver processor 452, a transmitter / receiver 456 and a transmitter processor 455, the transmitter / receiver 456 including an antenna 460.

[0216] In the transmission from the terminal to the IoT device, upper-layer packets are provided to the controller / processor 440. The controller / processor 440 implements functions of Layer 2 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 operation, retransmission of lost packets (if supported), and higher-layer signaling to the IoT device 450. The higher-layer information carried by the first PRDCH in this application is generated in the controller / processor 440. The transmit processor 415 implements various signal processing functions for Layer 1 (i.e., physical layer), including encoding, interleaving, scrambling, modulation, power control / allocation, precoding, and physical layer control signaling generation, such as the physical layer signal carrying the first PRDCH, which is completed in the transmit processor 415. The generated modulation symbols are divided into parallel streams, and each stream is mapped to a corresponding multicarrier subcarrier and / or multicarrier symbol. These are then transmitted by the transmit processor 415 via the transmitter 416 to the antenna 420 as radio frequency (RF) signals. At the receiver, each receiver 456 receives the RF signal through its corresponding antenna 460. Each receiver 456 recovers the baseband information modulated onto the RF carrier (if baseband processing is supported) and provides this baseband information to the receive processor 452. The receive processor 452 implements various signal reception and processing functions of the L1 layer. The signal reception and processing function includes receiving the physical layer signal carrying the first PRDCH in this application, performing 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 IoT device supports it). The controller / processor 490 is responsible for the L2 layer and above, and interprets higher-layer information, including the higher-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 computer-readable media.

[0217] In the transmission from IoT devices to terminals, similar to the transmission from terminals to IoT devices, the higher-layer information carried by the first PDRCH, after being generated by the controller / processor 490 (if supported by the IoT device), is processed by the transmitter processor 455 to perform various signal transmission processing functions for the L1 layer (i.e., physical layer). The transmitter processor 455, including the physical layer signal of the first PDRCH, is mapped to the antenna 460 via the transmitter 456 and transmitted as 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 receiver processor 412. The receiver processor 412 performs various signal reception processing functions for the L1 layer (i.e., physical layer) and then provides data and / or control signals to the controller / processor 440. The controller / processor 440 performs L2 layer functions, including interpreting the higher-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.

[0584] Example 12

[0585] Example 12 illustrates a structural block diagram of a processing device in a terminal according to an embodiment of this application, as shown in Figure 12. In Figure 12, the processing device 1200 in the terminal includes a first transceiver 1201. The first transceiver 1201 includes a transmitter / receiver 456 (including an antenna 460) as shown in Figure 4 of this application, a receive processor 452, and a controller / processor 490.

[0586] In embodiment 12, the first transceiver 1201 receives a first signaling, the first signaling configuring a first uplink signal, and the first uplink signal being used for the random access procedure of the terminal;

[0587] The first transceiver 1201 receives the first PDRCH, and the first PDRCH is the response to the first PDRCH;

[0588] There is an overlap between the time-domain resources allocated to the first uplink signal and the time-domain resources configured for the first PRDCH; the priority relationship between the first uplink signal and the first PRDCH depends on the relationship between the time-frequency resources occupied by the first uplink signal and the random access preamble.

[0589] As an example, when the first uplink signal carries a random access preamble or includes message A, the priority of the first PRDCH is higher than the priority of the first uplink signal; when the first uplink signal carries message 3 or the first uplink signal carries HARQ of message 4 or message B, the priority of the first uplink signal is higher than the priority of the first PRDCH.

[0590] As one embodiment, the priority transmission of either the first uplink signal or the first PRDCH depends on the capabilities of the terminal and the priority relationship between the first uplink signal and the first PRDCH. The capabilities of the terminal include the terminal's inability to simultaneously transmit both uplink transmission and R2D transmission.

[0591] As one embodiment, the first transceiver 1201 receives the second signaling;

[0592] The second signaling configures a second uplink signal, which is not used in the random access procedure of the terminal. When there is an overlap between the time domain resources allocated to the second uplink signal and the time domain resources configured for the first PRDCH, the first PRDCH is transmitted with priority.

[0593] As an example, whether the first PRDCH is prioritized for transmission also depends on at least one of the device type of the sender of the first PRDCH and the service type targeted by the first PRDCH, wherein the device type and the service type depend on the indication of the NAS or the core network.

[0594] As an example, the first PRDCH belongs to a first time window in the time domain, and the first time window includes at least one OFDM symbol;

[0595] Wherein, the start time of the first time window is later than the end time of the first PDRCH; the starting OFDM symbol included in the first time window is the earliest OFDM symbol that is later than the first PDRCH by a minimum time length, and the ending OFDM symbol included in the first time window is the latest OFDM symbol whose time interval with the first PDRCH is not greater than the maximum time length; the minimum time length is predefined or configured, and the maximum time length is equal to multiple OOK time units.

[0596] As an example, the first PRDCH uses OOK, and the target power value is equal to the transmit power value of the first PRDCH. The target power value is equal to the smaller of a first upper limit value and a first power value. At least one of the first upper limit value or the first power value depends on the number of OOK time units included in one OFDM symbol occupied by the first PRDCH in the time domain.

The second transceiver 1301 includes a transmitter / receiver 416 (including an antenna 460) as shown in Figure 4 of this application, a transmission processor 415, and a controller / processor 440.

[0599] The second transceiver 1301 sends the first PDRCH, and the first PDRCH is the response to the first PDRCH;

[0600] The first signaling configures a first uplink signal, which is used in the random access procedure of the receiver of the first PDRCH. The time-domain resources allocated to the first uplink signal and the time-domain resources configured for the first PDRCH overlap. The priority relationship between the first uplink signal and the first PDRCH depends on the relationship between the time-frequency resources occupied by the first uplink signal and the random access preamble.

[0601] As an example, when the first uplink signal carries a random access preamble or includes message A, the priority of the first PRDCH is higher than the priority of the first uplink signal; when the first uplink signal carries message 3 or the first uplink signal carries HARQ of message 4 or message B, the priority of the first uplink signal is higher than the priority of the first PRDCH.

[0602] As one embodiment, the priority transmission of either the first uplink signal or the first PRDCH depends on the capabilities of the receiver of the first PDRCH and the priority relationship between the first uplink signal and the first PRDCH. The capabilities of the receiver of the first PDRCH include whether the receiver of the first PDRCH supports simultaneous transmission of both uplink transmission and R2D transmission.

[0603] As an example, the second signaling configures a second uplink signal, which is not used in the random access procedure of the receiver of the first PDRCH. When there is an overlap between the time domain resources allocated to the second uplink signal and the time domain resources configured for the first PDRCH, the first PDRCH is transmitted with priority.

[0604] As an example, whether the first PRDCH is prioritized for transmission also depends on at least one of the device type of the IoT device and the service type targeted by the first PRDCH, wherein the device type and the service type depend on the indication of the NAS or the core network.

[0605] As an example, the first PRDCH belongs to a first time window in the time domain, and the first time window includes at least one OFDM symbol;

[0606] Wherein, the start time of the first time window is later than the end time of the first PDRCH; the starting OFDM symbol included in the first time window is the earliest OFDM symbol that is later than the first PDRCH by a minimum time length, and the ending OFDM symbol included in the first time window is the latest OFDM symbol whose time interval with the first PDRCH is not greater than the maximum time length; the minimum time length is predefined or configured, and the maximum time length is equal to multiple OOK time units.

[0607] As an example, the first PRDCH uses OOK, and the target power value is equal to the transmit power value of the first PRDCH. The target power value is equal to the smaller of a first upper limit value and a first power value. At least one of the first upper limit value or the first power value depends on the number of OOK time units included in one OFDM symbol occupied by the first PRDCH in the time domain.

The A-IoT device 1400 may also include an energy harvester, which can be either an RF energy harvester 1403 or a non-RF energy harvester 1407. The RF energy harvester 1403 may include a rectifier that performs RF signal (AC) to DC conversion. The RF energy harvester 1403 and the receiver / transmitter may share the antenna 1401, or they may use separate antennas. The energy-related module 1404 may include a power management unit (PMU) 1405; the PMU 1405 is responsible for storing energy from the energy harvester in energy storage 1406 and supplying power to active component blocks that require power. The energy-related module 1404 may also include energy storage 1406; the energy storage 1406 stores energy collected from the energy harvester, and the energy storage 1406 may be a capacitor. The processing module 1408 may include BB (Baseband) logic 1413 (if supported), memory 1418, and 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 non-volatile memory (NVM), such as EEPROM, for permanent storage of the device ID; the other is a register for temporarily storing information needed for operation only when energy in energy storage 1406 is available; the clock generator 1419 provides the required clock signal. The processing module 1408 may also include reception-related blocks 1409 and transmission-related blocks 1417, which may include different modules for different A-IoT devices.

[0611] As an example, for an A-IoT device 1400 with a peak power consumption of approximately 1 μW, the receive correlation module 1409 may include an RF BPF 1410, an RF envelope detector (RF-ED), a BB LPF 1411, and a comparator 1412. The transmit correlation module 1417 may include a backscatter modulator.

[0612] As a non-limiting embodiment, the output of the matching network 1402 is processed sequentially by the RF BPF 1410, the RF envelope detector, the BB LPF 1411, and the comparator 1412 before being 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.

At least one of R2D (Reader to device) / CW2D (Carrier-wave, or carrier-wave node, to device) and D2R (Device to reader) can be amplified by the reflection amplifier or the LNA. The large frequency shifter shifts the backscattered signal from one frequency (e.g., an FDD-DL frequency) to another frequency (e.g., an FDD-UL frequency).

[0614] As a non-limiting embodiment, the output of the matching network 1402 is processed sequentially through an RF BPF 1410, an LNA, an RF envelope detector, a BB amplifier, a BB LPF 1411, and a comparator / N-bit ADC 1412 before being input to the BB logic 1413. The output of the BB logic 1413 is then processed by a large frequency shifter, a backscatter modulator, and a reflection amplifier before being transmitted by the antenna 1401.

The output of the BB logic 1413 is then processed by a transmit modulator, a digital-to-analog converter, a low-pass filter, a mixer, a LO / FLL ( / PLL), and a power amplifier before being transmitted by the antenna 1401.

[0617] As an example, for an A-IoT device 1400 with peak power consumption less than or equal to several hundred μW, if an internally generated carrier wave is used and an intermediate frequency envelope detector (IF) receiver is employed, the receive-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 transmit-related module 1417 may include a transmit modulator, a digital-to-analog converter, a low-pass filter, a mixer, a LO / FLL ( / PLL), and a power amplifier. The IF amplifier amplifies the IF signal. The IF filter filters unwanted RF and LO signals. The IF envelope detector detects the envelope from the IF signal. The mixer in the receive-related module 1409 down-converts the RF signal to the IF stage. Depending on the implementation, there can be one or two mixers for both the transmitter and receiver.

The output of the BB logic 1413 is processed by a transmit modulator, a digital-to-analog converter, a low-pass filter, a mixer, a LO / FLL ( / PLL), and a power amplifier before being transmitted by the antenna 1401.

[0619] As an example, for an A-IoT device 1400 with peak power consumption less than or equal to several hundred μW, if an internally-generated carrier wave is used and a zero-IF (ZIF) receiver is employed, the receive-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 transmit-related module 1417 may include a transmit modulator, a digital-to-analog converter, a low-pass filter, a mixer, a LO / FLL ( / PLL), and a power amplifier. The mixer in the receive-related module 1409 down-converts the RF signal to the BB stage. Depending on the implementation, there may be one or two mixers for both the transmitter and receiver.

The BB LPF 1411 is used to filter out harmonics and high-frequency components, improving the input signal quality of the comparator / ADC 1412; depending on the implementation, the BB LPF 1411 may not be present. 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 improve signal strength and receiver 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 improve signal strength. The transmit modulator is used to modulate the baseband bits according to the modulation scheme; the transmit modulator may be part of the BB logic 1413. The digital-to-analog converter is used to convert the digital signal to an analog signal. The low-pass filter is used to filter out unwanted signals. The mixer in the transmit correlation module 1417 is used to upconvert the baseband signal to the RF range.
