Description

A method and apparatus for a node used in wireless communication Technical Field

[0001] This application relates to transmission methods and apparatus in wireless communication systems, and more particularly to bit stuffing schemes and apparatus 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) 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, and the existing 5G standard cannot fully meet the new demands. Therefore, 3GPP is preparing to begin preliminary research on 6G.

[0003] With the diversification of application scenarios and the emergence of new business models, the demand for low-complexity and low-power transmission solutions is increasing day by day. Therefore, 6G needs to explore better adaptation and support for low-complexity and low-power wireless transmission methods. Summary of the Invention

[0004] Research on low-power wake-up signal (LP-WUS) and Ambient Internet of Things (AIoT) was initiated in Rel-18 and Rel-19, respectively. On / off keying (OOK) is considered a potential key technology in both LP-WUS and AIoT. In the existing 5G LP-WUS research and standardization process, OOK is only used for downlink transmission and not for transmitting higher-layer data blocks (such as transport blocks or coded blocks). However, in AIoT, OOK is expected to be used for transmission from readers to IoT devices, and this research is just beginning. The applicant anticipates that OOK will be more widely used in future 6G networks, such as in 6G uplink transmission, OOK transmission between user equipment, and support for OOK transmission in a wider range of AIoT networks. The applicant's research also found that with AIoT and the expansion of OOK to broader application scenarios, bit generation for OOK transmission requires a new definition.

[0005] This application discloses a solution to the bit stuffing problem of signals using OOK in the future. It should be noted that the description in this application only uses uplink transmission and reader-to-IoT device transmission 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 requiring physical layer bit stuffing, or other scenarios that do not support forward error correction coding, 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). Furthermore, adopting a unified solution for different scenarios (including but not limited to eMBB, URLLC, energy saving, IoT, full-duplex networks, non-terrestrial networks, sensor-integrated networks, smart metasurfaces, terahertz networks, V2X scenarios) or different application parameters can help reduce hardware complexity and cost. Where there is no conflict, the embodiments and features in the embodiments used in the device used as the first node in this application can be applied to the device used as the second node in this application, and vice versa.

Figure 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for a user plane 350 and a control plane 300. Figure 3 shows the radio protocol architecture for the control plane 300 for a first node device (UE, Reader, or Device) and a second node device (gNB or Device) 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. Layer 1 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 first node device and the second node device via PHY 301. Layer L2 305 includes a MAC (Medium Access Control) sublayer 302, an RLC (Radio Link Control) sublayer 303, and a PDCP (Packet Data Convergence Protocol) sublayer 304, which terminate at the second node device. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. It also provides security through encrypted data packets and supports cross-cell mobility between second node devices and the first node device. The 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. The MAC sublayer 302 provides multiplexing between logical and transport channels. It is also responsible for allocating various radio resources (e.g., resource blocks) within a cell among first node devices. Furthermore, the MAC sublayer 302 handles HARQ operations. In the control plane 300, the RRC (Radio Resource Control) sublayer 306 of Layer 3 (L3 layer) is responsible for acquiring radio resources (i.e., radio bearers) and configuring the lower layers using RRC signaling between the second node device and the first node device. The radio protocol architecture of the user plane 350 includes Layer 1 (L1 layer) and Layer 2 (L2 layer). The radio protocol architecture for the first and second node devices in the user plane 350 is largely the same as the corresponding layers and sublayers in the control plane 300 for Physical Layer 351, PDCP sublayer 354 in L2 layer 355, RLC sublayer 353 in L2 layer 355, and MAC sublayer 352 in L2 layer 355. However, 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 also includes an SDAP (Service Data Adaptation Protocol) sublayer 356, which is responsible for mapping between QoS flows and data radio bearers (DRBs) to support service diversity. Although not illustrated, the first node device 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.).

The controller / processor 440 provides 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, and higher-layer signaling to the second node 450. The higher-layer information carried by the first signal and the second signal in this application (when the first signal and the second signal carry higher-layer information) 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 signal and the second signal being 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 physical layer signals carrying the first and second signals of 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 second node device 410 on the physical channel, and then providing the data and control signals to the controller / processor 490 (if supported by the second node). The controller / processor 490 is responsible for the L2 layer and above, and interprets higher-layer information, including interpreting the higher-layer information carried by the first and second signals respectively. 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.

[0311] In the transmission from the second node to the first node, similar to the transmission from the first node to the second node, after the higher-layer information is generated by the controller / processor 490 (if the second node supports it), it undergoes various signal transmission processing functions for the L1 layer (i.e., the physical layer) by the transmit processor 455. The transmit processor 455 transmits the information as radio frequency signals via transmitter 456 mapped to antenna 460. 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 receiver processor 412. Receiver processor 412 implements various signal reception processing functions for the L1 layer (i.e., the physical layer) and subsequently provides data and / or control signals to controller / processor 440. The L2 layer functions implemented in controller / processor 440 include interpreting the higher-layer information. The controller / processor may be associated with a buffer 430 that stores program code and data. Buffer 430 may be a computer-readable medium.
