Description

A method and apparatus for use in a communication node for wireless communication

[0001] This application claims priority to Chinese Patent Application No. 202410488874.X, filed on April 22, 2024, entitled "A method and apparatus for use in a communication node 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 methods and apparatus for indicating uplink control information. Background Technology

[0003] Existing NR (New Radio) systems divide spectrum resources into FDD (Frequency Division Duplexing) and TDD (Time Division Duplexing) spectrum. For TDD spectrum, both base stations and user equipment (UE) operate in half-duplex mode, which reduces resource utilization and increases latency. To address these issues, the 3GPP (3rd Generation Partnership Project) RAN (Radio Access Network) 1#103e meeting adopted the "Study on Evolution of NR Duplex Operation" (Study Item, SI), which proposed subband non-overlapping full duplex (SBFD) to support base station equipment in simultaneously transmitting and receiving on two subbands. In 3GPP Release 19, a Work Item (WI) was further initiated for subband non-overlapping full duplex.

[0004] The application scenarios of future wireless communication systems are becoming increasingly diversified, and different application scenarios place high-speed and low-latency performance requirements on the system. To meet the diverse performance needs of various application scenarios, 3GPP RAN completed the standardization work for "XR Enhancements for NR" in Release 18. This introduced multi-PUSCH configured grants. To avoid resource waste, it supports indicative use of UCI (Uplink Control Information) on the CG (Configured Grant)-PUSCH to tell the UE whether it will transmit the CG-PUSCH on subsequent CG-PUSCH TO (Transmission Occasion). For unpaired spectrum operation, the CG-PUSCH TO indicated by UTO (Unused Transmission Occasion)-UCI must exclude invalid CG-PUSCH TOs that cause the UE not to send PUSCH due to a collision between PUSCH and a downlink symbol indicated by tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated (if provided) or a symbol collision with an SS / PBCH block indexed by ssb-PositionsInBurst. Summary of the Invention

[0005] The inventors discovered through research that UTO-UCI indication is a critical issue in full-duplex scenarios. Due to the introduction of full-duplex, invalid CG-PUSCH TOs that cause the UE to not send PUSCHs due to collisions between PUSCH and downlink symbols indicated by tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated (if provided), or with symbols in the SS / PBCH block indexed by ssb-PositionsInBurst, can potentially become valid CG-PUSCH TOs. If existing rules are reused, the UE will not send CG-PUSCHs in this CG-PUSCH TO and will not indicate this CG-PUSCH TO in the UTO-UCI, affecting the UE's uplink transmission.

[0006] To address the aforementioned problems, this application provides a solution for indicating control information. While the NR system is used as an example in the problem description, this application is also applicable to scenarios such as LTE (Long-Term Evolution) or LTE-A (Long-Term Evolution Advanced) systems, achieving similar technical effects to NR systems. Furthermore, although this application provides a specific implementation for the uplink, it can also be used in scenarios such as the downlink, achieving similar technical effects. Furthermore, adopting a unified design scheme for different scenarios helps reduce hardware complexity and cost. Furthermore, although this application provides a specific implementation for XR scenarios, it can also be used in uplink enhancement scenarios, achieving similar technical effects to XR systems. Furthermore, although this application provides a specific implementation for PUSCH (Physical Uplink Shared Channel), it can also be used in scenarios such as PRACH, PUCCH, or PUSCH repetition, achieving similar technical effects to PUSCH. Furthermore, although this application was initially intended for the Uu air interface, it can also be used for the PC5 interface to achieve similar technical effects. Furthermore, although this application was initially intended for terminal and base station scenarios, it is also applicable to V2X (Vehicle-to-Everything) scenarios, communication scenarios between terminals and relays, and between relays and base stations, achieving similar technical effects. Furthermore, although this application was initially intended for terminal and base station scenarios, it is also applicable to IAB (Integrated Access and Backhaul) communication scenarios, achieving similar technical effects. Furthermore, although this application was initially intended for terrestrial network (TN) scenarios, it is also applicable to non-terrestrial network (NTN) communication scenarios, achieving similar technical effects. In addition, adopting a unified solution for different scenarios 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 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. The L1 layer will be referred to herein as PHY 301. Layer 2 (L2 layer) 305 is above PHY 301 and includes a MAC (Medium Access Control) sublayer 302, an RLC (Radio Link Control) sublayer 303, and a PDCP (Packet Data Convergence Protocol) sublayer 304. 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 cross-area mobility support. RLC sublayer 303 provides upper-layer packet segmentation and reassembly, retransmission of lost packets, and packet reordering to compensate for out-of-order reception caused by HARQ (Hybrid Automatic Repeat Request). 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. MAC sublayer 302 is also responsible for HARQ operations. 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 using RRC signaling to configure the lower layers. The radio protocol architecture of user plane 350 includes Layer 1 (L1 layer) and Layer 2 (L2 layer). In user plane 350, the radio protocol architecture 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 is largely the same as the corresponding layers and sublayers in control plane 300. 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.

[0377] In the transmission from the second communication device 410 to the first communication device 450, at the second communication device 410, upper-layer data packets from the core network are provided to the controller / processor 475. The controller / processor 475 implements L2 layer functionality. In the transmission from the second communication device 410 to the first communication device 450, the controller / processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to the first communication device 450 based on various priority metrics. The controller / processor 475 is also responsible for retransmitting lost packets and signaling to the first communication device 450. The transmit processor 416 and the multi-antenna transmit processor 471 implement various signal processing functions for the L1 layer (i.e., the physical layer). Transmit processor 416 performs encoding and interleaving to facilitate forward error correction (FEC) at the second communication device 410, and mapping of signal clusters based on various modulation schemes (e.g., Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK), M-Phase Shift Keying (M-PSK), M-QAM). Multi-antenna transmit processor 471 performs digital spatial precoding on the encoded and modulated symbols, including codebook-based and non-codebook-based precoding, and beamforming processing, generating one or more spatial streams. Transmit processor 416 then maps each spatial stream to subcarriers, multiplexes it with a reference signal (e.g., a pilot) in the time and / or frequency domains, and subsequently uses inverse fast Fourier transform (IFFT) to generate a physical channel carrying the time-domain multicarrier symbol stream. Multi-antenna transmit processor 471 then performs transmit analog precoding / beamforming operations on the time-domain multicarrier symbol stream. Each transmitter 418 converts the baseband multicarrier symbol stream provided by the multi-antenna transmitter processor 471 into an radio frequency stream, which is then provided to different antennas 420.

[0378] In the transmission from the second communication device 410 to the first communication device 450, at the first communication device 450, each receiver 454 receives a signal through its corresponding antenna 452. Each receiver 454 recovers the information modulated onto the radio frequency carrier and converts the radio frequency stream into a baseband multicarrier symbol stream, which is then provided to the receiver processor 456. The receiver processor 456 and the multi-antenna receiver processor 458 implement various signal processing functions of the L1 layer. The multi-antenna receiver processor 458 performs receive analog precoding / beamforming operations on the baseband multicarrier symbol stream from the receiver 454. The receiver processor 456 uses a Fast Fourier Transform (FFT) to convert the baseband multicarrier symbol stream after the receive analog precoding / beamforming operations from the time domain to the frequency domain. In the frequency domain, the physical layer data signal and the reference signal are demultiplexed by the receiver processor 456, where the reference signal is used for channel estimation, and the data signal is recovered in the multi-antenna receiver processor 458 after multi-antenna detection to recover any spatial stream destined for the first communication device 450. Symbols on each spatial stream are demodulated and recovered in the receive processor 456, generating soft decisions. The receive processor 456 then decodes and deinterleaves the soft decisions to recover the upper-layer data and control signals transmitted by the second communication device 410 over the physical channel. The upper-layer data and control signals are then provided to the controller / processor 459. The controller / processor 459 implements the functions of Layer 2. The controller / processor 459 may be associated with a memory 460 storing program code and data. The memory 460 may be referred to as computer-readable media. In the transmission from the second communication device 410 to the first communication device 450, the controller / processor 459 provides multiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transport and logical channels to recover upper-layer data packets from the core network. The upper-layer data packets are then provided to all protocol layers above Layer 2. Various control signals may also be provided to Layer 3 for Layer 3 processing.

[0379] In the transmission from the first communication device 450 to the second communication device 410, at the first communication device 450, a data source 467 is used to provide upper-layer data packets to the controller / processor 459. The data source 467 represents all protocol layers above the L2 layer. Similar to the transmission functions at the second communication device 410 described in the transmission from the second communication device 410 to the first communication device 450, the controller / processor 459 implements header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on radio resource allocation, implementing L2 layer functions for the user plane and control plane. The controller / processor 459 is also responsible for retransmitting lost packets and signaling to the second communication device 410. Transmit processor 468 performs modulation mapping and channel coding processing, while multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based and non-codebook-based precoding, and beamforming processing. Subsequently, transmit processor 468 modulates the generated spatial stream into a multi-carrier / single-carrier symbol stream. After analog precoding / beamforming operations in multi-antenna transmit processor 457, the stream is provided to different antennas 452 via transmitter 454. Each transmitter 454 first converts the baseband symbol stream provided by multi-antenna transmit processor 457 into a radio frequency symbol stream before providing it to antenna 452.

[0380] In the transmission from the first communication device 450 to the second communication device 410, the function at the second communication device 410 is similar to the receiving function at the first communication device 450 described in the transmission from the second communication device 410 to the first communication device 450. Each receiver 418 receives radio frequency signals through its corresponding antenna 420, converts the received radio frequency signals into baseband signals, and provides the baseband signals to the multi-antenna receiving processor 472 and the receiving processor 470. The receiving processor 470 and the multi-antenna receiving processor 472 jointly implement the L1 layer functions. The controller / processor 475 implements the L2 layer functions. The controller / processor 475 may be associated with a memory 476 that stores program code and data. The memory 476 may be referred to as computer-readable media. In the transmission from the first communication device 450 to the second communication device 410, the controller / processor 475 provides multiplexing between the transmission and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover upper-layer data packets from the UE 450.
