Description

A method and apparatus for use in terminals and base stations for wireless communication

[0001] This application claims priority to Chinese Patent Application No. 202411626028.6, filed on November 13, 2024, entitled "A Method and Apparatus in a Terminal and Base Station for Wireless Communication", 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 power control schemes and apparatus in wireless communication. 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, and the existing 5G standard cannot fully meet the new demands. Therefore, 3GPP is preparing to begin preliminary research on 6G.

[0004] 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

[0005] The 5G NR system initiated research on the Ambient Internet of Things (IoT) in Rel-19, where on / off keying (OOK) is considered a potential key technology. In the Ambient Physical Network (APN), OOK is expected to be used for transmission from readers to IoT devices, and this research is just beginning. The applicant's research has revealed that, with the expansion of OOK into Ambient Physical Networks and broader application scenarios, power control for OOK-based transmissions needs to be supported and defined, and currently, no existing power control scheme supports OOK.

[0006] To address the power control 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 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 power control or management, or other scenarios supporting power control or management, 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 also helps reduce hardware complexity and cost.

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 of a terminal (UE or gNB) and a base station (gNB or UE) 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 base station via PHY 301. L2 layer 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 base station. PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. PDCP sublayer 304 also provides security through encrypted data packets and supports inter-cell mobility between base stations. RLC sublayer 303 provides upper-layer data packet segmentation and reassembly, retransmission of lost data packets, and data packet reordering to compensate for out-of-order reception due to HARQ. 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 terminals. 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 base stations 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 base stations 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, 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. The SDAP sublayer 356 is responsible for mapping between QoS flows and data radio bearers (DRBs) to support service diversity. Although not illustrated, the terminal 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., remote UE, server, etc.).

[0247] Example 4

[0248] Example 4 shows a schematic diagram of a terminal device and a base station device according to an embodiment of the present application, as shown in Figure 4.

[0249] The terminal device (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.

[0250] The base station device (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, wherein the transmitter / receiver 416 includes an antenna 420.

[0251] In the DL (Downlink), upper-layer packets are provided to the controller / processor 440. The controller / processor 440 implements functions of Layer 2 and above. In the DL, the controller / processor 440 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to the terminal device 450 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 terminal device 450. The higher-layer information carried in the first information block 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 information block, 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 and provides the baseband information to the receive processor 452. The receive processor 452 implements various signal reception processing functions at Layer 1. These functions include receiving physical layer signals carrying the first information block of this application, demodulating the multicarrier symbols in the multicarrier symbol stream using various modulation schemes (e.g., Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK)), followed by descrambling, decoding, and deinterleaving to recover the data or control transmitted by the base station equipment 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 Layer 2 and above, and interprets higher-layer information. This includes interpreting the higher-level information carried in the first information block. 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.

[0252] In uplink (UL) transmission, similar to downlink transmission, after being generated by controller / processor 490, higher-layer information (including the second information block in this application) undergoes various signal transmission processing functions for the L1 layer (i.e., physical layer) by transmitter processor 455. Transmitter 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., physical layer) and subsequently provides data and / or control signals to controller / processor 440. Implementing L2 layer functions in controller / processor 440 includes interpreting higher-layer information. Controller / processor may be associated with buffer 430 storing program code and data. Buffer 430 may be computer-readable media.

[0253] In the transmission between the reader and the IoT device, similar to uplink and downlink transmissions, upper-layer packets (including upper-layer data included in the first PRDCH) are provided to the controller / processor 440. The controller / processor 440 implements L2 layer and above functions. The 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, such as the physical layer signal carrying the first PRDCH, which is completed in the transmit processor 415. The generated modulation symbols are split into parallel streams and each stream is mapped to a corresponding multicarrier subcarrier and / or multicarrier symbol, and then transmitted by the transmit processor 415 via transmitter 416 to antenna 420 as radio frequency signals. At the receiving end, each receiver 456 receives the radio frequency signal through its corresponding antenna 460, and each receiver 456 recovers the baseband information modulated onto the radio frequency carrier (if baseband processing is supported) and provides the baseband information to the receive processor 452. The receive processor 452 implements various L1 layer signal reception processing functions. 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 the memory 480 that stores program code and data.
