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 schemes and apparatus for delay design 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 signals (LP-WUS) and ambient Internet of Things (IoT) was initiated in Rel-18 and Rel-19 of the 5G NR system, respectively. On / off keying (OOK) is considered a potential key technology in both LP-WUS and Ambient Internet of Things. In the existing research and standardization process of 5G LP-WUS, OOK is only used for downlink LP-WUS transmission and not for uplink transmission. However, in Ambient Internet of Things, 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 broader IoT environment. Meanwhile, the applicant's research revealed that after extending OOK to a wider range of application scenarios in the environmental physical network, the latency relationship between OOK transmission and scheduling DCI also needs to be supported and defined, and there is no existing design that supports the latency relationship between OOK transmission and scheduling DCI.

[0005] To address the scheduling delay issue of signals using OOK in the future, this application discloses a solution. 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 OOK scheduling delay management, or other OOK-supporting scenarios, 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 in the embodiments used in the device of the first node in this application can be applied to the device of the second node in this application, and vice versa.

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.).

[0307] Example 4

[0308] Example 4 illustrates a schematic diagram of a first node and a second node according to an embodiment of this application, as shown in Figure 4.

[0309] The first node (410) may include a controller / processor 440, a data source / buffer 430, a receiver processor 412, a transmitter / receiver 416 and a transmitter processor 415, the transmitter / receiver 416 including an antenna 420.

[0310] The second node (450) may include a controller / processor 490, a data source / buffer 480, a receiver processor 452, a transmitter / receiver 456 and a transmitter processor 455, wherein the transmitter / receiver 456 includes an antenna 460.

[0311] In the transmission from the first node to the second node, upper-layer packets are provided to the controller / processor 440. The controller / processor 440 implements L2 layer and above functions. 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 and the first signal and the second signal are transmitted from the first node to the second node) and the first information block are generated in the controller / processor 440. Transmit processor 415 implements various signal processing functions for the L1 layer (i.e., the physical layer), including encoding, interleaving, scrambling, modulation, power control / distribution, precoding, and physical layer control signaling generation. For example, physical layer signals carrying a first signal and a second signal (when the first and second signals are transmitted from a first node to a second node) and physical layer signals carrying the first information block are processed in transmit processor 415. The generated modulation symbols are divided into parallel streams, and each stream is mapped to a corresponding multi-carrier subcarrier and / or multi-carrier symbol. These are then mapped by transmit processor 415 to antenna 420 via transmitter 416 and transmitted as radio frequency signals. At the receiving end, each receiver 456 receives the radio frequency signal 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 receiver processor 452. Receiver processor 452 implements various signal reception processing functions for the L1 layer. The signal reception and processing function includes receiving physical layer signals carrying the first and second signals of this application (when the first and second signals are transmitted from the first node to the second node) and physical layer signals carrying the first information block, 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. The controller / processor 490 is responsible for the L2 layer and above, and interprets higher-layer information, including interpreting the higher-layer information and the second information block 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.

[0312] 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, it undergoes various signal transmission processing functions for the L1 layer (i.e., the physical layer) by the transmitter processor 455. The transmitter processor 455 transmits the information as a radio frequency signal via the transmitter 456 mapped to the antenna 460. The first DCI in this application is generated in the transmitter processor 455. 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 implements 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 L2 layer functions implemented in the 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. The buffer 430 may be a computer-readable medium.
