Description

Technical Field

[0001] This application relates to transmission methods and apparatus in wireless communication systems, and more particularly to schemes and apparatus for multi-carrier transmission 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 more flexible and effective use of spectrum resources is increasing day by day. Therefore, 6G needs to explore new ways of using spectrum resources. Summary of the Invention

[0004] Both 4G and 5G systems support carrier aggregation (CA), which allows different frequency domain resources to be used together, increasing overall bandwidth and thus transmission rate and throughput. However, in existing 4G and 5G systems, each component carrier (CC) corresponds to a cell, and it does not support two or more component carriers corresponding to the same cell. This approach in existing 4G and 5G systems greatly limits the spectrum flexibility in carrier aggregation, especially limiting the use of many fragmented spectrum resources. As spectrum resources (especially low-frequency spectrum resources) become increasingly valuable, 6G networks need to find a flexible and efficient way to utilize spectrum resources. Having multiple carriers or spectrum distributed across multiple bands corresponding to the same cell, thus supporting uplink and downlink transmissions distributed across multiple carriers, is considered a more efficient means for 6G networks to utilize spectrum resources. When an uplink transmission is distributed across multiple carriers, the applicant's research found that when the PUSCH (Physical Uplink Shared Channel) carries uplink control information (UCI), it is mapped along with the entire transport block to all carriers included in the multiple carriers. Since the channel conditions on these carriers may differ, transmission performance on carriers with poor channel conditions is lower than that on carriers with good channel conditions, thus reducing the reliability of the transmitted uplink control information. Therefore, for scenarios where multiple carriers or spectrum distributed across multiple bands corresponds to the same cell, it is necessary to enhance the multiplexing of uplink control information to the uplink shared channel.

[0005] This application discloses a solution to the problem of reusing UCI to PUSCH. It should be noted that the description in this application uses multi-carrier single-cell (or single-cell multi-carrier) as a typical application scenario or example. This application is also applicable to 6G networks or other scenarios facing similar problems in the future (such as other scenarios that require the joint use of multiple carriers, or other scenarios that require the effective utilization of fragmented spectrum, such as 2G or 3G spectrum refarming, or other scenarios utilizing idle spectrum from non-cellular systems). For different application scenarios, such as eMBB, URLLC, full-duplex networks, IoT, sensor networks, integrated sensing networks, smart metasurfaces, and terahertz networks, V2X can also achieve similar technical effects. In addition, adopting a unified solution for different scenarios (including but not limited to eMBB, URLLC, full-duplex networks, IoT, sensor networks, integrated sensing networks, smart metasurfaces, terahertz networks, and V2X scenarios) or different application parameters can also help reduce hardware complexity and cost. Where there is no conflict, the embodiments and features in the embodiments used in the first node of this application can be applied to the embodiments used in the second node of this application, and vice versa.

[0358] Example 3

[0359] Example 3 illustrates a schematic diagram of a wireless protocol architecture for a user plane and a control plane according to 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 between the first node (UE or gNB) and the second node (gNB or UE) is illustrated 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. 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 first and second nodes via PHY301. 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 second node. 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 supports cross-regional mobility between the second and first nodes. 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. 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 the first nodes. 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 second and first nodes. The radio protocol architecture of user plane 350 includes Layer 1 (L1 layer) and Layer 2 (L2 layer). The radio protocol architecture for the first and second nodes 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 packets to reduce radio transmission overhead. L2 layer 355 in user plane 350 also includes SDAP (Service Data Adaptation Protocol) sublayer 356. SDAP sublayer 356 is responsible for mapping between QoS streams and Data Radio Bearers (DRBs) to support service diversity.Although not illustrated, the first node may have several upper layers above 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.).

[0367] Example 4

[0368] Example 4 illustrates a schematic diagram of a first node and a second node according to an embodiment of this application, as shown in the attached diagram. Figure 4 As shown.

[0369] The first node (450) may include a controller / processor 490, a memory 480, a receiver processor 452, a transmitter / receiver 456 and a transmitter processor 455, the transmitter / receiver 456 including an antenna 460.

[0370] The second node (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.

[0371] In the transmission from the second node (410) to the first node (450), upper-layer packets are provided to the controller / processor 440. The controller / processor 440 implements L2 and higher-layer functions. The controller / processor 440 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to the first node 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 first node 450. The higher-layer information carried in the first, second, third, and fourth information blocks of this application is 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 information block, a second information block, a third information block, and a fourth information block are generated 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 (RF) signals. At the receiving end, 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 receiver processor 452. Receiver processor 452 implements various L1 layer signal reception processing functions. The signal reception and processing function includes demodulating the physical layer signals carrying the first, second, third, and fourth information blocks of this application using multi-carrier symbols in a multi-carrier symbol stream based on various modulation schemes (e.g., Binary Phase Shift Keying (BPSK) and Quadrature Phase Shift Keying (QPSK)), followed by descrambling, decoding, and deinterleaving to recover the data or control signals transmitted by the second node device 410 on the physical channel. The data and control signals are then provided to the controller / processor 490. 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, second, third, and fourth information blocks. The controller / processor may be associated with a memory 480 that stores program code and data. The memory 480 may be referred to as a computer-readable medium.

[0372] In the transmission from the first node (450) to the second node (410), similar to the transmission from the second node (410) to the first node (450), higher-layer information, including a first signal (such as carrying higher-layer information), is generated by the controller / processor 490 and then processed by the transmitter processor 455 for various signal transmission processing functions for the L1 layer (i.e., the physical layer). The first signal is transmitted by the transmitter processor 455 via the transmitter 456 to the antenna 460 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 implements various signal reception processing functions for the L1 layer (i.e., the physical layer), including receiving and processing the first signal, and subsequently providing data and / or control signals to the controller / processor 440. The controller / processor 440 implements L2 layer functions, including interpreting higher-layer information such as the first signal (such as carrying higher-layer information). The controller / processor may be associated with memory 430, which stores program code and data. Memory 430 may be computer-readable media.

The first intermediate number, the number of bits included in the first control bit sequence, and the number of all REs in the frequency domain of the second symbol occupying the second symbol in the time domain that can be mapped to the first control bit sequence belonging to the partial carrier are used together to determine the distribution of all REs included in the first RE set occupying the second symbol in the time domain in the partial carrier.

[0502] As an example, all REs belonging to the partial carrier are occupied on non-last symbols, and the remaining control bits are distributed and mapped on the last symbol to obtain frequency selectivity gain and frequency diversity gain. This maximizes the use of existing standard mapping rules, and the design is simple with little standardization work.
