Description

Methods and apparatus related to rate matching in nodes used for wireless communication

[0001] This application claims priority to Chinese Patent Application No. 202410931141.9, filed on July 11, 2024, entitled "Method and Apparatus Related to Rate Matching in a 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 transmitting wireless signals in wireless communication systems supporting cellular networks. Background Technology

[0003] In existing NR (New Radio) systems, spectrum resources are statically divided into FDD (Frequency Division Duplex) and TDD (Time Division Duplex) spectrum. For TDD spectrum, both base stations and UEs (User Equipment) operate in half-duplex mode. This half-duplex mode avoids self-interference and mitigates the impact of cross-link interference (CLI), but it also leads to decreased resource utilization and increased latency. To address these issues, supporting flexible duplex modes or variable link directions (uplink, downlink, or flexible) on TDD or FDD spectrum has become a possible solution. The 3GPP (3rd Generation Partner Project) has agreed to conduct research on duplex technology (especially subband non-overlapping full duplex (SBFD) mode at the gNB (NR Node B) end); optimizing the system design accordingly is an important part of this research.

[0004] Rate matching is an important part of transmission channel processing. Summary of the Invention

[0005] For transmission signals spanning both full-duplex and non-full-duplex symbols, rate matching is a critical issue in system design; this application discloses a solution to this problem. It should be noted that this application is applicable to various wireless communication scenarios, such as scenarios using SBFD mode, scenarios using other types of full-duplex modes besides SBFD, and scenarios using more flexible duplex modes, achieving similar technical effects. Furthermore, using a unified solution across different scenarios (including but not limited to scenarios using SBFD mode, scenarios using other types of full-duplex modes besides SBFD, and scenarios using more flexible duplex modes) can help reduce hardware complexity and cost, or improve performance. Unless otherwise specified, embodiments and features in any node of this application can be applied to any other node. Unless otherwise specified, embodiments and features in any node of this application can be arbitrarily combined with each other.

Figure 3 shows the radio protocol architecture for a first communication node device (UE, gNB, or V2X (Vehicle to Everything) RSU (Road Side Unit), on-board equipment, or on-board communication module) and a second communication node device (gNB, UE, or V2X RSU, on-board equipment, or on-board communication module), or the control plane 300 between two UEs, using three layers: Layer 1 (L1), Layer 2 (L2), and Layer 3 (L3). L1 is the lowest layer and implements various PHY (Physical Layer) signal processing functions. L1 will be referred to herein as PHY301. Layer 2 (L2) 305 sits above PHY 301 and is responsible for the link between the first and second communication node devices and between the two UEs via PHY 301. 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 communication 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-region mobility between the second and first communication node devices. 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 (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 among the first communication node devices. MAC sublayer 302 is also responsible for HARQ operations. The RRC (Radio Resource Control) sublayer 306 in 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 the second and first communication node devices.The radio protocol architecture of user plane 350 includes Layer 1 (L1) and Layer 2 (L2). The radio protocol architecture for the first and second communication node devices 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 (Quality of Service) streams and Data Radio Bearers (DRBs) to support service diversity. Although not illustrated, the first communication node device may have several upper layers above the L2 layer 355, including a network layer (e.g., the IP (Internet Protocol) 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.).

[0176] Example 4

[0177] Example 4 illustrates a schematic diagram of a first communication device and a second communication device according to this application, as shown in Figure 4. Figure 4 is a block diagram of a first communication device 410 and a second communication device 450 communicating with each other in an access network.

[0178] The first communication device 410 includes a controller / processor 475, a memory 476, a receiver processor 470, a transmitter processor 416, a multi-antenna receiver processor 472, a multi-antenna transmitter processor 471, a transmitter / receiver 418, and an antenna 420.

[0179] The second communication device 450 includes a controller / processor 459, a memory 460, a data source 467, a transmitting processor 468, a receiving processor 456, a multi-antenna transmitting processor 457, a multi-antenna receiving processor 458, a transmitter / receiver 454, and an antenna 452.

[0180] In the transmission from the first communication device 410 to the second communication device 450, at the first 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 first communication device 410 to the second 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 second communication device 450 based on various priority metrics. The controller / processor 475 is also responsible for retransmitting lost packets and signaling to the second 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 450, 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-Quadrature Amplitude Modulation (M-QAM)). Multi-antenna transmit processor 471 performs digital spatial precoding on the encoded and modulated symbols, including codebook-based precoding and non-codebook-based precoding, and beamforming processing to generate one or more spatial streams. Transmit processor 416 then maps each spatial stream to a subcarrier, multiplexes it with a reference signal (e.g., a pilot) in the time and / or frequency domains, and then uses an 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 multi-antenna transmit processor 471 into an RF stream, which is then provided to a different antenna 420.

[0181] In the transmission from the first communication device 410 to the second communication device 450, at the second 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 second 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 first 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 first communication device 410 to the second 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.

[0182] In the transmission from the second communication device 450 to the first communication device 410, at the second 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 first communication device 410 described in the transmission from the first communication device 410 to the second 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 first 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.

[0183] In the transmission from the second communication device 450 to the first communication device 410, the function at the first communication device 410 is similar to the receiving function at the second communication device 450 described in the transmission from the first communication device 410 to the second 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 second communication device 450 to the first 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. Upper-layer packets from the controller / processor 475 can be provided to the core network.

[0280] As one example, the first parameter group includes multiple parameters.

[0281] As an example, each of the plurality of parameters included in the first parameter group is a parameter used to configure a set of rate matching modes.

[0283] As an example, the first parameter is any parameter in the first parameter group, and the first parameter is a parameter used to indicate resource elements (REs) that are declared unavailable; only when the first parameter is configured, one bit included in the K1 bits in the first field of the first signaling indicates that the resource elements (REs) indicated by the first parameter that are declared unavailable are applied to the rate matching of the first sub-signal.

[0284] As an example, the first parameter is any parameter in the first parameter group, and the first parameter is a parameter used to indicate resource elements (REs) that are declared not to be available for PDSCH; only when the first parameter is configured, one bit included in the K1 bits in the first field of the first signaling indicates that the resource elements (REs) indicated by the first parameter that are declared not to be available for PDSCH are applied to the rate matching of the first sub-signal.

[0292] As an example, one bit in the first field of the first signaling can indicate both that the resource elements (REs) declared as unavailable as indicated by the first parameter are applied to the rate matching of the first sub-signal, and that the resource elements (REs) declared as unavailable as indicated by the second parameter are applied to the rate matching of the second sub-signal.

[0385] As one example, there are two time slots among the plurality of time slots:

[0386] In one of the two time slots, the corresponding portion of the time domain resources allocated to the first signal is subject to different in-slot symbol allocations compared to the corresponding portion of the time domain resources allocated to the first signal in the other of the two time slots.

[0387] As an example, in each of the plurality of time slots, a corresponding portion of the time domain resources allocated to the first signal is used for the transmission of the first signal in that time slot.

[0388] As an example, in each of the plurality of time slots: the corresponding portion of the time-domain resources allocated to the first signal includes only full-duplex symbols, or the corresponding portion of the time-domain resources allocated to the first signal includes only non-full-duplex symbols.

[0402] As one embodiment, the first signaling includes indication information of frequency domain resources allocated to the first signal in a full-duplex symbol.

[0403] As one embodiment, the first signaling includes indication information of frequency domain resources allocated to the first signal in a non-full-duplex symbol.

[0434] As an example, symbols indicated by the uplink / downlink TDD configuration signaling as downlink and usable for uplink transmission are full-duplex symbols; symbols indicated by the uplink / downlink TDD configuration signaling as downlink and not usable for uplink transmission are non-full-duplex symbols.

[0435] As an example, symbols indicated as uplink by the uplink / downlink TDD configuration signaling cannot be used for downlink transmission.
