Description

Technical Field

[0001] This application relates to transmission methods and apparatus in wireless communication systems, and more particularly to schemes and apparatus related to signal encoding in wireless communication. 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) in Rel-19. In this Ambient Internet of Things, OOK (Outputless Kinematics) 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. The applicant anticipates that A-IoT will also become an important component of future 6G networks. Furthermore, the applicant's research has revealed that with the development of A-IoT and the expansion of OOK to a wider range of applications, the coding scheme for OOK transmissions will require a new definition.

[0004] This application discloses a solution to the problem of encoding control information and data information for signals using OOK in the future. It should be noted that the description in this application only uses the transmission from the reader to 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., scenarios where OOK encoding needs to be considered, or scenarios where control information and data information of OOK channels are multiplexed, such as scenarios supporting energy saving, or scenarios supporting user equipment to user equipment transmission, 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).

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 (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. 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. 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 the logical and transport channels. MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) within a cell among first-node 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 layer using RRC signaling between the IoT device and the terminal. 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.).

[0329] Example 4

[0330] 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 the attached diagram. Figure 4 As shown.

[0331] 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.

[0332] 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.

[0333] 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 first PRDCH and the first signal in this application, which are performed 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 first PRDCH and the first signal 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 terminal 410 on the physical channel, and then providing the data and control signals to controller / processor 490 (if supported by the IoT device). Controller / processor 490 is responsible for Layer 2 and above, and interprets higher-layer information, including the higher-layer information carried by the first PRDCH in this application. The controller / processor may be associated with memory 480, which stores program code and data. Memory 480 may be referred to as computer-readable media.

[0334] In transmissions from IoT devices to terminals, similar to those from terminals to IoT devices, higher-layer information is generated by the controller / processor 490 (if the IoT device supports it) and then processed by the transmitter processor 455 to perform various signal transmission processing functions for the L1 layer (i.e., the physical layer). Physical layer signals are transmitted by the transmitter processor 455 via transmitter 456 to antenna 460 as radio frequency signals. Receivers 416 receive the radio frequency signals through their respective antennas 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., the physical layer) and subsequently provides data and / or control signals to the controller / processor 440. The controller / processor 440 implements L2 layer functions, including interpreting 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.
