Description

Technical Field

[0001] This application relates to transmission methods and apparatus in wireless communication systems, and more particularly to schemes and apparatus for the ability to simultaneously receive signals in Internet of Things (IoT) communications. Background Technology

[0002] 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) technology 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

[0003] The 5G NR system initiated research on Ambient Internet of Things (A-IoT) at 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, the ability of reader devices to decode D2R signals at the RF end under the premise of conflict between downlink transmission and D2R transmission at the base station is still being considered. Furthermore, research on the hardware conditions and capabilities design of the readers is still in its initial stages. The applicant also anticipates that A-IoT will become an important component in future 6G networks, and the capability design of readers for 5G NR is highly likely to be adopted in 6G networks.

[0004] To address the issue of readers simultaneously transmitting downlink and D2R capabilities, this application discloses a solution. It should be noted that the description in this application only 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.

[0228] Example 3

[0229] Example 3 illustrates a schematic diagram of a wireless protocol architecture for the user plane and control plane according to an embodiment of this application, as shown in the attached diagram. Figure 3 As shown. Figure 3 This is a schematic diagram illustrating an embodiment of a radio protocol architecture for the user plane 350 and the control plane 300. Figure 3The radio protocol architecture for the control plane 300 used by terminals and IoT devices is illustrated 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. L1 layer will be referred to as PHY301 in this document. Layer 2 (L2 layer) 305 sits above PHY301 and is responsible for the link between the terminal and the IoT device via PHY301. L2 layer 305 includes a MAC (Medium Access Control) sublayer 302, an RLC (RadioLink 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. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. The PDCP sublayer 304 also provides security through encrypted data packets and provides mobility support between IoT devices for the terminal device.

[0243] 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.

[0244] 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.
